Abstract
Description
Technical Field
[0001] This application relates to the technical field of brake disc grinding, and more particularly to a multi-station brake disc grinding equipment. Background Technology
[0002] As a key component of the automotive braking system, the brake disc is usually used in conjunction with the brake caliper and brake pads. When the vehicle needs to decelerate or brake, the brake caliper pushes the brake pads to clamp the brake disc, using friction to convert the vehicle's kinetic energy into heat energy, thereby reducing the vehicle speed or stopping it.
[0003] Brake discs are typically formed through mold casting. Due to metal residue, burrs or raised edges may form on their circumferential surface. These burrs make the surface rough and uneven. Directly grinding the inner edge, outer edge, or circumferential surface of the brake disc can affect its positioning and clamping during grinding, thus impacting grinding accuracy. Therefore, deburring is usually necessary before grinding. However, most manufacturers manually remove these burrs using files or sandpaper before grinding the disc. This manual deburring method increases the overall grinding time and reduces grinding efficiency. Furthermore, some processes require chamfering. Since chamfering is based on the intersection of the outer edge and the circumferential surface, grinding the circumferential surface after chamfering will change the intersection, causing the chamfer angle or position to deviate from the process requirements, thus affecting grinding accuracy.
[0004] Therefore, how to integrate the deburring of brake discs with the inner edge, outer edge, and annular surface grinding and chamfering operations into the same processing equipment, while optimizing the processing sequence to ensure grinding accuracy, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0005] In view of the shortcomings of the above-mentioned related technologies, the purpose of this application is to provide a multi-station brake disc grinding equipment to solve the technical problems of low efficiency in deburring by manual labor in existing brake disc grinding equipment, and the unreasonable processing sequence of inner edge, outer edge, annular surface grinding and chamfering operations, which leads to low grinding accuracy.
[0006] To achieve the above and other related objectives, this application provides a multi-station brake disc grinding apparatus for grinding brake discs. The brake disc is generally annular, having an inner edge, an outer edge, and opposing first and second annular surfaces. The multi-station brake disc grinding apparatus includes: a base with opposing first and second sides, the first side having an annular surface processing area, and the second side having a pre-treatment area; a pre-treatment mechanism for deburring the brake disc before outer edge grinding, including a first dressing mechanism located at the distal end of the pre-treatment area for deburring the first annular surface of the horizontally placed brake disc, and a second dressing mechanism located at the proximal end of the pre-treatment area for simultaneously deburring the second annular surface of the brake disc and grinding the inner edge; and an outer edge grinding mechanism located in the pre-treatment area and on the first side of the pre-treatment mechanism for performing outer edge grinding after the annular surface grinding operation. The pretreatment and chamfering processes include an outer edge grinding device for performing outer edge grinding and chamfering operations on the vertically placed brake disc; a flipping device located near the outer edge grinding device for switching the brake disc between a horizontal and vertical placement state; and a transport device straddling the flipping device for transporting the vertically placed brake disc. A transfer mechanism located in the center of the pretreatment area is used to rotate the brake disc between the first dressing mechanism, the second dressing mechanism, and the flipping device. An annular grinding mechanism located in the annular processing area includes three annular grinding devices for simultaneously grinding the first and second annular surfaces of the vertically placed brake disc from the transport device; and a rotating mechanism located between the three annular grinding devices and the outer edge grinding device for rotating the brake disc, after annular grinding, to the outer edge grinding device.
[0007] In summary, the multi-station brake disc grinding equipment provided in this application integrates deburring, inner edge grinding, toroidal grinding, outer edge grinding, and chamfering operations into a single processing flow by sequentially arranging a pretreatment area and a toroidal processing area on the same base. The equipment utilizes a first dressing mechanism and a second dressing mechanism in the pretreatment area to perform deburring on the first and second toroidal surfaces of the brake disc, respectively, while simultaneously completing inner edge grinding in the second dressing mechanism. This achieves automation and coordination of deburring and inner edge grinding, significantly improving pretreatment efficiency and eliminating human error. Furthermore, by setting up a toroidal grinding mechanism and an outer edge grinding mechanism in the toroidal processing area, and combining them with the linkage control of a transfer mechanism, a tilting device, a handling device, and a rotating mechanism, the brake disc can be automatically tilted and sequentially transferred in both horizontal and vertical states, thereby achieving high-precision connection and synchronized cycle time between the grinding stations. This design not only shortens the overall processing cycle and improves the automation and production efficiency of multi-station grinding of brake discs, but also effectively avoids the impact of chamfer offset and positioning error on grinding accuracy by optimizing the processing sequence and positioning method, thus ensuring the dimensional consistency and surface quality stability of the finished brake discs.

[0045] In view of the technical problems mentioned in the background art, this application discloses a multi-station grinding equipment for brake discs. By sequentially arranging a pretreatment area and a toroidal processing area on the same base, the deburring, inner edge grinding, toroidal grinding, outer edge grinding, and chamfering operations of the brake disc are integrated into a single processing flow. The equipment, by setting a first dressing mechanism and a second dressing mechanism in the pretreatment area to perform deburring on the first and second toroidal surfaces of the brake disc respectively, and simultaneously completing inner edge grinding in the second dressing mechanism, achieves automation and coordination of deburring and inner edge grinding, significantly improving pretreatment efficiency and eliminating human error. Furthermore, by setting a toroidal grinding mechanism and an outer edge grinding mechanism in the toroidal processing area, and combining the linkage control of a transfer mechanism, a tilting device, a handling device, and a rotating mechanism, the brake disc can achieve automatic tilting and sequential transfer in both horizontal and vertical states, thereby achieving high-precision connection and synchronous cycle between the grinding stations. This design not only shortens the overall processing cycle and improves the automation and production efficiency of multi-station grinding of brake discs, but also effectively avoids the impact of chamfer offset and positioning error on grinding accuracy by optimizing the processing sequence and positioning method, thus ensuring the dimensional consistency and surface quality stability of the finished brake discs.
[0046] To clarify the definition of direction and the operation between different structures, the embodiments disclosed in this application define a three-dimensional space defined by the horizontal, vertical, and longitudinal directions, where the horizontal, vertical, and longitudinal directions are all straight lines and are mutually perpendicular. For example, the direction of the length extension of the base bottom is defined as horizontal (as shown in the figure). Figure 2 The direction of the arrow X in the diagram is defined as the longitudinal direction (as shown by the arrow X in the diagram). Figure 2 The direction of the arrow Y in the diagram is used to define the vertical direction, also known as the vertical direction or the up-down direction (as shown in the diagram). Figure 2 (The direction of arrow Z in the image).
[0047] To clearly illustrate the positional relationships between the various devices, components, structures, or mechanisms in the embodiments of this application, along the longitudinal direction of the base, the side where the second dressing mechanism is located in the multi-station brake disc grinding equipment is defined as the proximal end, and the side of the multi-station brake disc grinding equipment away from the second dressing mechanism is defined as the distal end. That is, the proximal end and the distal end correspond to opposite sides of the multi-station brake disc grinding equipment, which are opposite to each other or far apart.
[0048] In any embodiment provided in this application, the brake disc refers to a generally annular shape; specifically, please refer to [link to relevant documentation]. Figure 1 The image shown is a schematic diagram of the shape of the brake disc in one embodiment of this application, as follows: Figure 1As shown, the brake disc 1 has an outer edge 11, an inner edge 12, and an annular surface 13. Further, the annular surface 13 includes a first annular surface and a second annular surface facing each other. It should be noted that the first annular surface and the second annular surface are only used to distinguish two opposing annular surfaces on the brake disc 1, and do not specifically refer to any one annular surface. In the embodiments described in this application, the first annular surface refers to the downward-facing annular surface when the brake disc is in a horizontal position, and the second annular surface refers to the upward-facing annular surface when the brake disc is in a horizontal position. Furthermore, unless otherwise specified, the annular surface mentioned in subsequent embodiments of this application refers to two opposing annular surfaces; for example, the annular surface grinding operation refers to grinding both annular surfaces of the brake disc simultaneously.
[0049] In practical applications, the outer edge 11 may have ventilation slots or holes to enhance heat dissipation, and the inner edge 12 may have holes 121 for fixing and connecting the wheel hub. These holes 121 are located on the protruding structure 122 of the inner edge. In some embodiments, the brake disc is also referred to as a brake disc. In the embodiments described in this application, the outer edge 11 of the brake disc 1 has a diameter of approximately 840 mm, the inner edge 12 has a diameter of approximately 356 mm, and a thickness of approximately 80 mm.
[0050] It should be understood that the brake disc is typically formed by mold casting. During the manufacturing process, burrs or protrusions may form on the annular surface of the brake disc due to metal residue. These burrs or protrusions are the burrs described in the foregoing and subsequent embodiments. These burrs make the annular surface uneven, which in turn affects the positioning and clamping of the brake disc during the grinding process, causing wobbling during grinding and thus affecting the grinding accuracy. In view of this, before performing the formal grinding operation on the brake disc, a pretreatment operation such as deburring is required.
[0051] The multi-station grinding equipment for brake discs described in this application is used for grinding brake disc 1. Please refer to... Figure 2 and Figure 3 The figures shown are schematic diagrams of the multi-station brake disc grinding equipment in one embodiment of this application, viewed from different angles. Figure 2 and Figure 3 As shown, the brake disc multi-station grinding equipment 2 includes a base 21, a pretreatment mechanism 22, an outer edge grinding mechanism 23, a transfer mechanism 24, and a ring surface grinding mechanism 25.
[0052] In one embodiment, the base 21, as the main component of the multi-station brake disc grinding equipment 2 of this application, can be configured with a heavy material such as stainless steel or cast iron to provide robust overall stability. In some examples, the base 21 includes fixing or limiting structures for supporting different mechanisms or components in the multi-station brake disc grinding equipment 2, such as a base, column, or frame. In some examples, the base 21 can be a single, integrated base. In some examples, the base 21 can include multiple independent bases.
[0053] In one embodiment, the base 21 has opposing first and second sides, in Figure 3 In the example shown, the first side corresponds to the space region on the left side of the base 21, and the second side corresponds to the space region on the right side of the base 21. In this example, as... Figure 3 As shown, the first side has an annular machining area 211, and the second side has a pretreatment area 212. It should be noted that, in subsequent embodiments, to clearly illustrate the relative positions of various components, structures, assemblies, mechanisms, members, or devices in the brake disc multi-station grinding equipment 2, the annular machining area 211 and the pretreatment area 212 of the base 21 are used as a reference for differentiation. The side (or end) of each component, structure, assembly, mechanism, member, or device that is relatively closer to the annular machining area 211 is referred to as the first side (or first end), and the side (or end) that is relatively closer to the pretreatment area 212 is referred to as the second side (or second end). Furthermore, given that... Figure 3 Taking the annular processing area 211 located on the left and the pre-processing area 212 located on the right as an example, in subsequent embodiments, the first side will also be referred to as the left side, the second side as the right side, the first end as the left end, and the second end as the right end.
[0054] In one embodiment, it is presented as follows Figure 3 As indicated by the dashed lines, the base 21 has a toroidal machining area 211 and a pre-treatment area 212. It should be noted that in the examples provided in this application, each machining area is defined by the travel path and range of the machining device corresponding to that area. For example, the toroidal grinding mechanism 25 is located in the toroidal machining area 211, and the range of the toroidal machining area 211 is the area occupied by the toroidal grinding mechanism 25 during the toroidal grinding operation. Similarly, the pre-treatment mechanism 22 and the outer edge grinding mechanism 23 are located in the pre-treatment area 212, and the range of the pre-treatment area 212 is the area occupied by the pre-treatment mechanism 22 and the outer edge grinding mechanism 25 during the deburring, outer edge grinding, and chamfering operations, respectively.
[0055] In one embodiment, the pretreatment mechanism 22 is used to deburr the brake disc before the outer edge is ground. For example... Figure 3As shown, the pretreatment mechanism 22 includes a first trimming mechanism 221 and a second trimming mechanism 222. The first trimming mechanism 221 is located at the far end of the pretreatment area 212 and is used to deburr the first annular surface of the horizontally placed brake disc. The second trimming mechanism 222 is located at the near end of the pretreatment area 212 and is used to simultaneously deburr the second annular surface of the brake disc and perform grinding operations on the inner edge.
[0056] Please see Figure 4 The image shown is a schematic diagram of the structure of the first trimming mechanism in one embodiment of this application. Figure 4 As shown, the first trimming mechanism 221 includes a first deburring device 2211, which is used to deburr the first annular surface of the horizontally placed brake disc.
[0057] Please see Figure 5 The diagram shows a structural schematic of the deburring device in one embodiment of this application, as shown below. Figure 5 As shown, the first deburring device 2211 includes a base 2212 and a first deburring wheel 2213. The base 2212 is disposed on the base 21. The axis of the first deburring wheel 2213 is perpendicular to the base 2212 and is used to deburr the first annular surface of the horizontally placed brake disc 1.
[0058] In one embodiment, the base 2212 is used to support the main structure of the first dressing mechanism 23. In some examples, the base 2212 may be configured as a high-strength material such as cast iron, carbon structural steel, or aluminum alloy to ensure its support stability. In some examples, the base 2212 has a mounting surface, which can be used to install structures or devices such as the first deburring wheel 2213. Specifically, as... Figure 5 As shown, the first deburring wheel 2213 is connected to the upper end of the first deburring spindle 2210, and the first deburring wheel 2213 is set on the base 2212 by the installation of the first deburring spindle 2210 on the mounting plane.
[0059] In one embodiment, the first deburring spindle 2210 extends vertically through the mounting plane, and a drive shaft is fixedly mounted at its center. The drive shaft is connected to the center of the first deburring grinding wheel 2213, thereby driving the first deburring grinding wheel 2213 to rotate, so as to deburr the first annular surface of the brake disc 1 through the upper surface of the first deburring grinding wheel 2213. In this embodiment, the first deburring grinding wheel 2213 also provides a working platform for grinding the first annular surface.
[0060] In one embodiment, such as Figure 5As shown, the first deburring device 2211 further includes a first grinding wheel drive structure 2214, which is disposed on the other side of the base 2212 and is used to drive the first deburring grinding wheel 2213 to rotate. Specifically, the first grinding wheel drive structure 2214 can drive the transmission shaft to rotate, thereby driving the first deburring grinding wheel 2213 to rotate, so as to grind the first annular surface of the brake disc 1.
[0061] In one embodiment, such as Figure 5 As shown, the first grinding wheel drive structure 2214 includes a first grinding wheel drive motor 22141 and a transmission belt 22142. The first grinding wheel drive motor 22141 is vertically disposed on the base 2212, and the transmission belt 22142 is connected to the output shaft of the first grinding wheel drive motor 22141. Specifically, the output shaft of the first grinding wheel drive motor 22141 and the transmission belt 22142 are disposed on the lower side of the mounting plane to reduce the installation space. The power generated by the first grinding wheel drive motor 22141 is transmitted to the transmission belt 22142 through the output shaft, and then transmitted by the transmission belt 22142 to the drive shaft of the first deburring spindle 2210, thereby allowing the first deburring grinding wheel 2213 to rotate around the drive shaft. In one example, the first grinding wheel drive motor 22141 is configured as a rotary motor.
[0062] In one embodiment, the first deburring wheel 2213 is configured as a coarse grinding wheel. See also... Figure 6 The image shows a schematic diagram of the structure of the first deburring wheel in one embodiment of this application. Figure 6 As shown, the first deburring wheel 2213 is circular and has a through hole in the middle. The drive shaft of the first deburring spindle 2210 is connected to the first deburring wheel 2213 through the through hole. In some examples, the first deburring wheel 2213 is formed by bonding abrasive grains with a binder, forming a surface with abrasive grains that rotates in contact with the first annular surface of the brake disc 1 to be ground. The abrasive grains have a certain abrasive grain size and density. In some examples, the abrasive grains can be made of materials with a hardness greater than that of the brake disc 1 material, such as aluminum oxide, silicon carbide, or cubic boron diamond nitride, depending on the needs of grinding the brake disc 1. In some examples, the first deburring wheel 2213 has vents for heat dissipation.
[0063] In one embodiment, such as Figure 6As shown, the first deburring grinding wheel 2213 has multiple spaced arc-shaped cooling grooves 22131 through which coolant can pass. In one example, the coolant can be provided by a cooling device to cool the first deburring grinding wheel 2213, reducing surface damage during grinding and improving grinding efficiency and service life. In one implementation, the cooling device includes a cooling source through which coolant can be drawn to the arc-shaped cooling grooves 22131 on the first deburring grinding wheel 2213 to cool the first annular surface of the brake disc. In this embodiment, the arc-shaped design of the cooling grooves increases the residence time of the coolant within the grooves, thereby ensuring a cooling effect. In some examples, the coolant is configured as cooling water.
[0064] In one embodiment, such as Figure 5 As shown, a waterproof structure 2215 is provided on the periphery of the first deburring wheel 2213 to prevent the coolant from splashing. Specifically, the waterproof structure 2215 can concentrate the coolant on the periphery of the first deburring wheel 2213, avoiding disorderly splashing of grinding fluid caused by the centrifugal force generated by the rotation of the first deburring wheel 2213.
[0065] In one implementation, the waterproof structure 2215 is configured to include a waterproof cover and a waterproof cover lifting unit. The waterproof cover is annular and surrounds the periphery of the first deburring wheel 2213. In one example, the waterproof cover has a bottom surface and an annular sidewall surrounding the bottom surface. In this example, when the first deburring wheel 2213 deburrs the first annular surface, the waterproof cover lifting unit can drive the waterproof cover to rise and surround the first deburring wheel 2213. Under the shielding effect of the sidewall of the waterproof cover, the coolant is trapped and carried into the interior of the waterproof cover. In one example, the waterproof cover lifting unit is configured as a lifting motor connected to the waterproof cover.
[0066] In one embodiment, the diameter of the first deburring wheel 2213 is smaller than the diameter of the brake disc 1. It should be understood that before deburring the first annular surface, the brake disc 1 needs to be clamped by the transfer mechanism 24 described in a subsequent embodiment and placed on the first deburring wheel 2213 for grinding. Therefore, in this embodiment, the first deburring wheel 2213, with a diameter smaller than that of the brake disc 1, avoids mechanical collisions when the transfer robot 22 places the brake disc 1.
[0067] However, in embodiments where the diameter of the first deburring wheel 2213 is smaller than the diameter of the brake disc 1, the first deburring wheel 2213 can only grind the middle portion of the first annular surface, and cannot grind the entire annular surface. Therefore, in one embodiment, as... Figure 5As shown, the first dressing mechanism 221 described in this application further includes a pressing and swaying device 2216, which is disposed above the first deburring device 2211 and is used to press and drive the brake disc 1 to sway. The pressing and swaying device 2216 can expand the grinding range of the first deburring wheel 2213 on the first annular surface, thereby taking into account the grinding of the entire annular surface.
[0068] Please see Figure 7 and combined Figure 4 ,in, Figure 7 The diagram shown is a structural schematic of the anti-rocking device in one embodiment of this application. Figure 7 As shown, the anti-swing device 2216 includes a swing unit 2217, which can drive the brake disc 1 to swing. Figure 7 In the illustrated embodiment, the rocking unit 2217 includes a rocking base 22171, a mounting structure 22172, and a rocking drive structure 22173.
[0069] In one embodiment, the rocker seat 22171 is disposed on the base 2212. Specifically, as shown... Figure 5 As shown, the mounting plane of the base 2212 has a mounting hole 22121, and the rocker seat 22171 is generally cylindrical and is mounted on the base 2212 through the mounting hole 22121, for example, by screwing. In this embodiment, the rocker seat 22171 has a rocker shaft inside, and the axis of the rocker shaft is perpendicular to the mounting plane, allowing it to rotate relative to the rocker seat 22171.
[0070] In one embodiment, such as Figure 7 As shown, the mounting structure 22172 is disposed on the rocker seat 22171. In one example, the second side of the mounting structure 22172 is connected to the rocker shaft of the rocker seat 22171, so that the first side of the mounting structure 22172 can rock around the rocker shaft, thereby causing the brake disc 1 to rock relative to the first deburring wheel 2213. In some examples, the mounting structure 22172 is configured as a rocker arm connected to the rocker shaft.
[0071] In one embodiment, such as Figure 7 As shown, a rocker arm 22174 for driving the brake disc 1 to rock is provided on one side of the mounting structure 22172. Specifically, the rocker arm 22174 can fix the brake disc 1 and, driven by the mounting structure 22172, cause the brake disc 1 to rock around the rocker axis relative to the first deburring wheel 2213, so as to achieve uniform and comprehensive grinding of the brake disc 1.
[0072] Please see Figures 8 to 10 ,in, Figure 8 and Figure 9 The following are schematic diagrams of the swing member from different perspectives in one embodiment of this application. Figure 10 The diagram shown is a cross-sectional view of the oscillating member fixing the brake disc in one embodiment of this application. Figure 9 and Figure 10 As shown, the oscillating member 22174 has a pressing surface 22175 on its lower side, which can contact the second annular surface of the brake disc, thereby pressing the first annular surface of the brake disc 1 against the first deburring wheel 2213 for oscillating grinding. In one example, the oscillating member 22174 is configured as an inverted disc-shaped structure, and the pressing surface 22175 is a circular plane with a diameter smaller than that of the brake disc 1.
[0073] In one embodiment, such as Figures 8 to 10 As shown, a plurality of elastic limiting portions 22176 are provided on the pressing surface 22175, and the plurality of elastic limiting portions 22176 can fix the brake disc 1. Figure 10 As shown, the elastic limiting part 22176 is configured as a rod-shaped structure, and an elastic element is disposed at the top end of the rod-shaped structure so that the elastic limiting part 22176 and the brake disc 1 are in elastic contact. Please refer to... Figure 1 As mentioned above, the inner edge 12 of the brake disc 1 has a hole 121, and the elastic limiting part 22176 can be inserted into the hole 121 to fix the brake disc 1. Furthermore, the elastic limiting part 22176 is in a relaxed state when inserted into the hole 121, and in a compressed state when not inserted into the hole 121 and in contact with the protruding structure 122. In this embodiment, the elastic limiting part 22176 ensures that the rocker arm 22174 fixes the brake disc 1, while avoiding hard contact with the brake disc 1 when fixing it.
[0074] In one embodiment, such as Figure 9 As shown, 12 elastic limiting portions 22176 are arranged at intervals along the circumference. Specifically, all 12 elastic limiting portions 22176 can extend into the inner edge of the brake disc. In some examples, not all elastic limiting portions 22176 can be inserted into the hole 121. In this example, the elastic limiting portions 22176 that cannot be inserted into the hole 121 can fall freely on the protruding structure 122 to be in a compressed state, or fall in the gap between the protruding structures 122 to be in a relaxed state. It is only necessary to ensure that the number of elastic limiting portions 22176 inserted into the hole 121 is sufficient to stably fix the brake disc 1 with the rocker arm 22174. In this embodiment, the transfer mechanism 24 only needs to place the brake disc 1 on the first deburring wheel 2213 to complete the transfer operation, without adjusting the orientation of the brake disc 1 so that the elastic limiting portions 22176 must correspond one-to-one with the holes 121, saving transfer time and thus improving processing efficiency.
[0075] In one embodiment, each time deburring is performed, at least four elastic limiting portions 22176 can be inserted into the holes 121 on the inner edge of the brake disc 1 to fix the brake disc 1. In some examples, the number of elastic limiting portions 22176 that can be inserted into the holes 121 can be 4, 5, 6, 7, 8, 9, 10, 11, or 12, etc., and the number of elastic limiting portions 22176 that cannot be inserted into the holes 121 corresponds to 8, 7, 6, 5, 4, 3, 2, 1, or 0, respectively.
[0076] In one embodiment, such as Figure 9 As shown, auxiliary positioning portions 22177 are also provided on the pressing plane 22175, spaced apart from the elastic limiting portions 22176. Figure 9 In the example shown, the auxiliary positioning part 22177 is configured as a protrusion with a height lower than that of the elastic limiting part 22176, which helps to limit the elastic limiting part 22176 to the inner edge of the brake disc.
[0077] As mentioned earlier, since the diameter of the first deburring wheel 2213 is smaller than the diameter of the brake disc 1, it is necessary to use the rocker arm 22174 to drive the brake disc 1 to swing so that the grinding range of the first deburring wheel 2213 completely covers the brake disc 1. Specifically, when the transfer mechanism 24 places the brake disc 1 on the first deburring wheel 2213, the brake disc 1 and the first deburring wheel 2213 have a relative initial position. During deburring, the rocker arm 22174 will drive the brake disc 1 to swing around the rocker axis between the first position and the second position under the mounting structure 22172.
[0078] Please see Figures 11 to 13 ,in, Figure 11 The diagram shown is a schematic representation of the brake disc and the first deburring wheel in their initial positions according to one embodiment of this application. Figure 12 The diagram shown is a schematic representation of the brake disc and the first deburring wheel in a first position according to one embodiment of this application. Figure 13 This application presents a schematic diagram of the brake disc and the first deburring wheel in a second position in one embodiment. It should be noted that... Figures 11 to 13 The first deburring grinding wheel 2213 is indicated by a dashed line, the brake disc 1 by a solid line, the axis of the oscillating shaft by point O, the center of the first deburring grinding wheel 2213 by point O1, and the center of the brake disc 1 by point O2. (See diagram below.) Figure 11 As shown, in the initial position, the center O1 of the first deburring wheel 2213 coincides with the center O2 of the brake disc 1. Subsequently, the brake disc 1, driven by the rocker component 22174, swings counterclockwise around the axis O of the rocker shaft until... Figure 11The first position shown is then rotated clockwise around the axis O of the swing shaft until... Figure 12 The second position is shown. In other words, during the deburring process of the first annular surface, the center O1 of the first deburring wheel 2213 is fixed, while the center O2 of the brake disc 1 oscillates bidirectionally around the axis O.
[0079] It should be noted that, Figure 11 The first position shown and Figure 12 The second position shown is merely illustrative, indicating the relative position of the brake disc 1 and the first deburring wheel 2213 when the brake disc 1 has its smallest swing angle. That is, when the brake disc 1 swings between the first and second positions, the grinding range of the first deburring wheel 2213 just covers the first annular surface of the brake disc 1. In practical applications, the swinging component 22174 can drive the brake disc 1 to swing at a larger angle to ensure comprehensive grinding.
[0080] In one embodiment, the swing member 22174 drives the brake disc 1 to swing at an angle of 5-10°. For example, it can be approximately 5°, 6°, 7°, 8°, 9°, or 10°, but it is not limited to this. The specific angle should be determined according to the difference between the diameter of the first deburring wheel 2213 and the diameter of the brake disc 1.
[0081] In one embodiment, such as Figure 7 As shown, the swing drive structure 22173 is disposed on one side of the swing base 22171 and is used to drive the mounting structure 22172 to swing around the swing axis to drive the swing component 22174 to swing.
[0082] In one embodiment, such as Figure 7 As shown, the swing drive structure 22173 includes a swing drive motor 221731, a first swing gear 221732, and a second swing gear 221733. The swing drive motor 221731 is disposed on the swing base 22171. The first swing gear 221732 is connected to the swing drive motor 221731. The second swing gear 221733 is disposed on the mounting structure 22172 and meshes with the first swing gear 221732. The swing drive motor 221731 drives the first swing gear 221732 to rotate, thereby causing the mounting structure 22172 to swing around the swing axis.
[0083] In one embodiment, such as Figure 7 As shown, the pressing and swaying device 2216 also includes a pressing unit 2219, which can press the brake disc 1 against the first deburring wheel 2213. Figure 7In the example shown, the pressing unit 2219 includes a pressing drive structure 22191, which is disposed on the mounting structure 22172 and is used to drive the mounting structure 22172 to perform lifting and lowering movements, so as to cause the pressing surface 22175 of the rocker member 22174 to press or release the brake disc 1.
[0084] In one example, the clamping drive structure 22191 may be configured to include a clamping telescopic rod disposed vertically within the rocker seat 22171, and a clamping lifting cylinder disposed on the mounting structure 22172 for driving the clamping telescopic rod to extend and retract, thereby causing the mounting structure 22172 to move up and down. Specifically, the clamping lifting cylinder drives the clamping telescopic rod to extend, which can cause the mounting structure 22172 to rise, thereby causing the rocker component 22174 to rise to a height that does not interfere with the transfer mechanism 24 in its transfer operation. The clamping lifting cylinder drives the clamping telescopic rod to retract, which can cause the mounting structure 22172 to descend, thereby causing the rocker component 22174 to descend, so as to press the brake disc 1 onto the first deburring grinding wheel 2213, and ensure that the brake disc 1 is pressed onto the first deburring grinding wheel 2213 throughout the entire rocking motion, thereby ensuring the grinding effect of the deburring process.
[0085] In one embodiment, such as Figure 7 As shown, the mounting structure 22172 is further provided with a rotary drive structure 22192 adjacent to the clamping drive structure 22191. The rotary drive structure 22192 is used to drive the rocker member 22174 to rotate, thereby causing the brake disc 1 to rotate in the opposite direction relative to the first deburring wheel 2213. For example, if the first deburring wheel 2213 rotates clockwise, the rotary drive structure 22192 will drive the brake disc 1 to rotate counterclockwise; if the first deburring wheel 2213 rotates counterclockwise, the rotary drive structure 22192 will drive the brake disc 1 to rotate clockwise. In this embodiment, the first deburring wheel 2213 and the brake disc 1 rotate in opposite directions, further improving the efficiency of deburring. In one example, the clamping drive structure 22191 is configured to include a rotary motor.
[0086] In one embodiment, such as Figure 9 and Figure 10 As shown, the pressure-operated rocking device 2216 also includes a nozzle 2218 disposed at the center of the rocking member 22174 for discharging coolant to the brake disc 1. Specifically, the cooling device described in the foregoing embodiment can be disposed in the rocking member 22174 and communicate with the nozzle 2218, so that coolant can be sprayed from the nozzle 2218 onto the brake disc 1, and then flow to the arc-shaped cooling groove 22131 on the first deburring wheel 2213, where it exerts a cooling effect and is then collected by the waterproof structure 2215. In one example, the nozzle 2218 can spray the coolant in a fan shape to enhance the cooling effect.
[0087] The following combination Figures 4 to 13 The process of deburring the first annular surface of the brake disc 1 using the first trimming mechanism 22 of this application is described in detail.
[0088] First, the transfer mechanism 24 transfers the brake disc 1 onto the first deburring wheel 2213. At this time, the brake disc 1 and the first deburring wheel 2213 are located at... Figure 11 The initial position is shown. Then, the pressing drive structure 22191 of the pressing rocker device 2216 drives the mounting structure 22172 to descend, so that the elastic limiting portion 22176 and the auxiliary positioning portion 22177 on the pressing plane 22175 of the rocker member 22174 are positioned in the inner edge of the brake disc 1, while at least four elastic limiting portions 22176 are inserted into the holes 121 of the brake disc 1 to present... Figure 10 The state shown. At this time, the brake disc 1 is pressed between the first deburring wheel 2213 and the rocker element 22174 and presents... Figure 4 The state is shown. Then, the first deburring wheel 2213 rotates at high speed under the drive of the first wheel drive structure 2214, and the brake disc 1 rotates in the opposite direction to the first deburring wheel 2213 under the drive of the rotation drive structure 22192. At the same time, the brake disc 1 rotates in the opposite direction to the first deburring wheel 2213 under the drive of the swing drive structure 22173. Figure 12 The first position shown and Figure 13 The brake disc 1 is oscillating between the second positions shown until the deburring of the first annular surface is completed. After the deburring is completed, the transfer mechanism 24 transfers the brake disc 1 to the second dressing mechanism 222 for deburring of the second annular surface and inner edge grinding.
[0089] In one embodiment, such as Figure 3 As shown, the second trimming mechanism 222 is disposed in the pretreatment area 212 and located near the transfer mechanism 24 to receive the brake disc 1 after the first deburring operation. Please refer to... Figure 14 The diagram shows a schematic representation of the structure of the second trimming mechanism in one embodiment of this application. Figure 14 As shown, the second finishing mechanism 222 includes a second deburring device 2221 and an inner edge grinding device 2222. The second deburring device 2221 is arranged in parallel along the transverse direction and is used to deburr the second annular surface of the horizontally placed brake disc 1. The inner edge grinding device 2222 is used to perform grinding operations on the inner edge of the brake disc 1.
[0090] In one embodiment, such as Figure 14As shown, the second trimming mechanism 222 also includes a support frame 2223, which is laterally arranged on the base 21 for mounting the second deburring device 2221 and the inner edge grinding device 2222. In some examples, the support frame 2223 may be configured as a gantry frame to support the components or structures in the second deburring device 2221 and the inner edge grinding device 2222, but it is not limited to this. It may be configured as any frame, beam, or box, as long as it can provide stable load-bearing capacity.
[0091] Please see Figure 15 and combined Figure 14 ,in, Figure 15 The diagram shown is a structural schematic of the second deburring device in one embodiment of this application. Figure 14 and 15 As shown, the second deburring device 2221 includes a first grinding frame 22211 and a deburring assembly 22212. The first grinding frame 22211 is movably mounted on the support frame 2223. The deburring assembly 22212 is used to deburr the second annular surface of the brake disc 1. In some examples, the first grinding frame 22211 serves as a carrier for the deburring assembly 22212 mounted on the support frame 2223, and its specific form can be a beam, column, plate frame, bracket, etc.
[0092] In one embodiment, such as Figure 15 As shown, the deburring assembly 22212 includes a second deburring spindle 22213 and a second deburring grinding wheel 22214. The second deburring spindle 22213 is fixedly mounted vertically on the first grinding frame 22211, and the second deburring grinding wheel 22214 is disposed at the end of the second deburring spindle 22213 for deburring the second annular surface of the brake disc 1.
[0093] In one embodiment, the second deburring spindle 22213 includes a drive shaft connected to a second deburring wheel 22214. In some examples, the drive shaft may be connected to a rotary drive motor that drives the drive shaft to rotate at high speed, thereby causing the second deburring wheel 22214 to rotate at high speed to deburr the second annular surface of the brake disc 1.
[0094] In one embodiment, the second deburring wheel 22214 is configured as a coarse grinding wheel. In one example, as... Figure 14 As shown, the diameter of the second deburring wheel 22214 is larger than the width of the annular surface of the brake disc 1, so that when performing deburring, the grinding range of the second deburring wheel 22214 can completely cover the second annular surface of the rotating brake disc, thereby ensuring the comprehensiveness of the grinding.
[0095] In one embodiment, the second deburring device 2221 further includes a first lateral moving structure and a first lifting structure. The first lateral moving structure is disposed on the support frame 2223 and is used to drive the first grinding frame 22211 to move laterally on the support frame 2223. The first lifting structure is disposed on the first grinding frame 22211 and is used to drive the deburring assembly 22212 to move vertically. In this embodiment, the deburring assembly 22212 moves relative to the support frame 2223 under the drive of the first grinding frame 22211. Figure 15 The arrows in the diagram indicate horizontal and vertical movement.
[0096] In one embodiment, the first lateral movement structure may include a first lateral movement guide rail, a first lateral movement lead screw, and a first lateral movement drive motor disposed on the support frame 2223. The first lateral movement drive motor drives the first lateral movement lead screw to rotate, thereby causing the deburring assembly 22212 to move on the first lateral movement guide rail. In some other examples, the first lateral movement structure may be configured to include a lateral movement rack, a lateral movement gear, and a lateral movement gear drive motor, in addition to the first lateral movement guide rail. The lateral movement rack may be arranged parallel to the first lateral movement guide rail. The lateral movement drive gear meshes with the lateral movement rack. The lateral movement gear drive motor is associated with the lateral movement gear. The lateral movement gear drive motor drives the connected lateral movement gear to rotate. Through the meshing of the lateral movement gear and the lateral movement rack, the deburring assembly 22212 is moved on the first lateral movement guide rail.
[0097] In one embodiment, the first lifting structure includes a first lifting moving guide rail disposed vertically on the first grinding frame 22211, a first lifting moving slider disposed on the second deburring spindle 22213 and connected to the first lifting moving guide rail, and a first lifting moving cylinder disposed on the first grinding frame 22211 for driving the first lifting moving slider to slide on the first lifting moving guide rail to drive the deburring assembly 22212 to perform lifting and lowering movements.
[0098] In practical applications, to ensure stable lifting and lowering of the deburring assembly 22212 on the first grinding frame 22211, a dual-rail design can be adopted, i.e., two first lifting and lowering guide rails can be used, which can be arranged in parallel. Furthermore, the first lifting and lowering cylinder can be further configured to include a first lifting and lowering lead screw and a first lifting and lowering motor, wherein the first lifting and lowering lead screw is vertically aligned and connected to the deburring assembly 22212, and the first lifting and lowering motor is connected to the lead screw. Thus, the first lifting and lowering motor drives the first lifting and lowering lead screw to rotate, thereby enabling the deburring assembly 22212 to move up and down along the first lifting and lowering guide rails. The implementation of the first lifting structure is not limited to this; other components that can drive the deburring assembly 22212 to move up and down along the vertical guide rails are also applicable. For example, the first lifting structure may include a first lifting and lowering rack, a first lifting drive gear meshing with the first lifting and lowering rack, and a first lifting drive motor that drives the first lifting drive gear to rotate.
[0099] Please see Figure 16 and combined Figure 14 ,in, Figure 16 The diagram shown is a structural schematic of an inner edge grinding device in one embodiment of this application. Figure 14 and Figure 16 As shown, the inner edge grinding device 2222 includes a second grinding frame 22221 and an inner edge grinding assembly 22222. The second grinding frame 22221 is movably mounted on a support frame 2223. The inner edge grinding assembly 22222 is used to perform grinding operations on the inner edge of the brake disc. In some examples, the second grinding frame 22221 serves as a carrier for the inner edge grinding assembly 22222 on the support frame 2223, and its specific form can be a beam, column, plate, bracket, etc.
[0100] In one embodiment, such as Figure 16 As shown, the inner edge grinding assembly 22222 includes an inner edge grinding spindle 22223 and an inner edge grinding wheel 22224. The inner edge grinding spindle 22223 is vertically fixed on the second grinding frame 22221, and the inner edge grinding wheel 22224 is disposed at the end of the inner edge grinding spindle 22223 for performing inner edge grinding operations. The structure of the inner edge grinding spindle 22223 and the inner edge grinding wheel 22224 can be referred to the description of the second deburring spindle 22213 and the second deburring wheel 22214 in the previous embodiments, and will not be repeated here.
[0101] In one embodiment, the inner edge grinding device 2222 further includes a second lateral moving structure and a second lifting structure. The second lateral moving structure is disposed on the support frame 2223 and is used to drive the second grinding frame 22221 to move laterally on the support frame 2223. The second lateral moving structure is disposed on the second grinding frame 22221 and is used to drive the inner edge grinding assembly 22222 to perform lifting movements. The second lateral moving structure may have the same configuration as the aforementioned first lateral moving structure, and the second lifting structure may have the same configuration as the aforementioned first lifting structure; details can be found in the preceding description and will not be repeated here.
[0102] In one embodiment, the second deburring device 2221 and the inner edge grinding device 2222 operate simultaneously to perform deburring on the second annular surface of the brake disc while simultaneously grinding the inner edge of the brake disc. Specifically, the first lateral moving structure and the second lateral moving structure can simultaneously drive the deburring assembly 22212 and the inner edge grinding assembly 22222 to move laterally relative to each other, so that the second deburring wheel 22214 and the inner edge grinding wheel 22224 respectively reach above the brake disc 1. Subsequently, the first lifting structure and the second lifting structure simultaneously drive the deburring assembly 22212 and the inner edge grinding assembly 22222 to descend, so that the second deburring wheel 22214 and the inner edge grinding wheel 22224 respectively contact the second annular surface and the inner edge of the brake disc 1. In this embodiment, the diameter of the inner edge grinding wheel 22224 is smaller than the diameter of the second deburring wheel 22214, ensuring that the inner edge grinding wheel 22224 does not interfere with the second deburring wheel 22214 performing rough grinding on the second annular surface when it extends into the inner edge of the brake disc to perform inner edge grinding. In one example, the inner edge grinding wheel 22224 is configured as a rough grinding wheel. In some examples, the working time of the second deburring device 2221 in deburring the second annular surface is equal to the time of the inner edge grinding device 2222 in performing inner edge grinding.
[0103] In one embodiment, such as Figure 14 As shown, the second dressing mechanism 222 also includes a grinding wheel dressing device 2224 for dressing the second deburring wheel 22214 and the inner edge grinding wheel 22224. Figure 14 In the example shown, the grinding wheel dressing device 2224 is configured as two to dress the second deburring grinding wheel 22214 and the inner edge grinding wheel 22224 respectively, so as to avoid wear or dulling of the grinding wheel after long-term inner edge grinding operation, thereby ensuring grinding accuracy.
[0104] In one embodiment, the grinding wheel dressing device 2224 includes a grinding wheel dressing assembly, a dressing drive structure, and a support. The grinding wheel dressing assembly is used to dress the grinding wheel, and the dressing drive structure is disposed below the grinding wheel dressing assembly to drive the grinding wheel dressing assembly toward the grinding wheel. The support is disposed below the dressing drive structure to enable the grinding wheel dressing assembly to reach a preset dressing height. The preset dressing height refers to the height of the dressing surface of the grinding wheel dressing assembly relative to the base 21 when dressing the rim of the grinding wheel.
[0105] In one embodiment, the support is a supporting structure for the grinding wheel dressing assembly and the dressing drive structure. In some examples, its bottom end can be fixedly connected to the base 21 by means of screws or other methods. In some examples, the height of the support is fixed; in practical applications, the installation height of the support can be determined in advance according to the preset dressing height. In other examples, the height of the support is adjustable; in practical applications, the specific dressing height can be adjusted manually or automatically. In this example, a locking structure can be provided on the support; when the support is adjusted to the required dressing height, the locking structure can lock the support to the corresponding position.
[0106] In one embodiment, the grinding drive structure is configured to include a grinding rotary drive motor for driving the grinding wheel grinding assembly to rotate toward or away from the grinding wheel as a whole, so that the grinding wheel grinding assembly rotates toward the grinding wheel to perform grinding operations, and rotates in the opposite direction after grinding to a position that does not interfere with the inner edge grinding operation or deburring treatment.
[0107] In one embodiment, the grinding wheel dredging assembly is positioned facing the grinding wheel and includes a tool setting detector and a grinding stone. The tool setting detector determines whether the grinding wheel needs dredging, and the grinding stone is used to dredging the grinding wheel. Specifically, before dredging, the tool setting detector first moves to a position close to the grinding wheel. After confirming that the grinding wheel needs dredging, the tool setting detector retracts to a position that does not interfere with the work of the grinding stone, and then the grinding stone contacts the grinding wheel for dredging. After dredging is completed, the tool setting detector moves close to the grinding wheel again for inspection to ensure that the dredging operation meets the dredging requirements. In some examples, the grinding stone may be configured as an oilstone to remove passivated abrasive grains from the surface of the grinding wheel.
[0108] In one embodiment, such as Figure 14 As shown, the second trimming mechanism 222 also includes a brake disc support device 2225 disposed at the distal end of the support frame 2223 for horizontally placing the brake disc 1. Please refer to... Figure 17 The image shown is a structural schematic diagram of a brake disc support device in one embodiment of this application. Figure 17As shown, the brake disc support device 2225 includes a support seat 22251 and a clamping unit 22252. The support seat 22251 is disposed on the base 21, and the clamping unit 22252 is disposed on the support seat 22251 for supporting the brake disc 1. Specifically, after the first annular surface of the brake disc 1 is deburred under the operation of the first dressing mechanism 221, the outer edge of the brake disc 1 can be clamped by the transfer mechanism 24 and transferred to the clamping unit 22252. The clamping unit 22252 clamps the outer edge for inner edge grinding and deburring of the second annular surface.
[0109] It should be noted here that, Figure 14 The brake disc support device 2225 shown is surrounded by a cover. Figure 17 The omission of the brake disc support device 2225 structure of the cover should not be construed as a limitation on the embodiment.
[0110] In one embodiment, the support 22251 supports the clamping unit 22252 and the brake disc. In some examples, it may be made of stainless steel, cast iron, or other materials to ensure support stability. In some examples, the support 22251 is configured as a seat on the base 21, and a rotating shaft may be disposed therein, so that the clamping unit 22252 can hold the brake disc and rotate it around the rotating shaft for grinding the brake disc.
[0111] In one embodiment, such as Figure 17 As shown, the clamping unit 22252 includes a support ring 22253 and a claw 22254. The support ring 22253 is used to support the brake disc, and the claw 22254 is disposed around the support ring 22253 to clamp the brake disc.
[0112] In one embodiment, the outer diameter of the support ring 22253 is smaller than the diameter of the brake disc, thereby avoiding mechanical collisions of the transfer mechanism 24 when placing the brake disc 1.
[0113] In one embodiment, the jaws 22254 are configured as a three-jaw structure, which can retract inward relative to the rotational axis to clamp the brake disc or open outward to release the brake disc. Further, the angle between adjacent jaws is 120°, thereby providing a uniform clamping force to the brake disc. In some examples, the side of the jaws 22254 used to clamp the outer edge of the brake disc may be covered with a rubber sheet to enhance the clamping stability of the brake disc.
[0114] In one embodiment, the clamping unit 22252 further includes an opening and closing drive unit for driving the jaws 22254 to perform opening and closing movements to clamp or release the brake disc. The opening and closing drive unit can be configured to drive the jaws 22254 in a helical drive mode or a linear drive mode to push them to retract inward or open outward to achieve clamping or releasing of the brake disc.
[0115] The following combination Figures 14 to 17 The process of deburring the second annular surface of the brake disc 1 and grinding the inner edge using the second dressing mechanism 222 of this application is described in detail.
[0116] First, the transfer mechanism 24 transfers the brake disc, which has undergone deburring of the first annular surface, to the brake disc support device 2225, where the outer edge of the brake disc is held by the jaws 22254. Then, the second deburring device 2221 and the inner edge grinding device 2222 operate simultaneously. The first and second lateral movement structures simultaneously drive the deburring assembly 22212 and the inner edge grinding assembly 22222 to move laterally relative to each other, so that the second deburring wheel 22214 and the inner edge grinding wheel 22224 reach above the brake disc 1. Afterward, the first and second lifting structures simultaneously drive the deburring assembly 22212 and the inner edge grinding assembly 22222 to descend, so that the second deburring wheel 22214 and the inner edge grinding wheel 22224 contact the second annular surface and the inner edge of the brake disc 1, respectively, until the deburring of the second annular surface and the grinding of the inner edge are completed.
[0117] In one embodiment, such as Figure 3 As shown, the transfer mechanism 24 is located in the middle of the pretreatment area 212 and is used to transfer the brake disc 1 between the first dressing mechanism 221 and the second dressing mechanism 222 in a rotating manner. Specifically, the transfer mechanism 24 can place the brake disc 1 horizontally on the first deburring grinding wheel 2213 of the first dressing mechanism 221. After the deburring of the first annular surface is completed, the transfer mechanism 24 can transfer the brake disc 1 and place it horizontally on the support ring 22253 of the second dressing mechanism 222 for deburring of the second annular surface and inner edge grinding.
[0118] Please see Figure 18 The diagram shown is a structural schematic of the transfer mechanism in one embodiment of this application. Figure 18 As shown, the transfer mechanism 24 includes a transport seat 241, a rotating shaft 242, and a clamping unit 243. It should be noted that, to distinguish it from the first clamping unit included in the handling device 233 described in subsequent embodiments, the clamping unit 243 included in the transfer mechanism 24 is referred to as the second clamping unit 243. The second clamping unit 243 will not be described further in subsequent references.
[0119] The transport seat 241 is disposed on the base 21, and the rotating shaft 242 is disposed vertically on the transport seat 241. The second clamping unit 243 is disposed above the transport seat 241 and can rotate around the rotating shaft 242 for clamping the horizontally placed brake disc 1. In this embodiment, the second clamping unit 243 can clamp the brake disc 1 around the rotating shaft 242 relative to the transport seat 241. Figure 18 The dashed lines in the diagram indicate clockwise and counterclockwise rotation to facilitate the transfer of the brake disc 1 between the first dressing mechanism 221 and the second dressing mechanism 222. In some examples, the carrier 241 may be made of high-strength materials such as cast iron or stainless steel to ensure sufficient rigidity and stability.
[0120] In one embodiment, the rotating shaft 242 may be configured as a hollow structure, and a bearing may be disposed between the transport seat 241 and the rotating shaft 242. In some examples, an angle encoder may be disposed inside the rotating shaft 242, which provides rotation information of the rotating shaft 242 driving the second clamping unit 243. The rotation information may include, for example, a rotation angle and a rotation direction, which may be determined by the relative position of the brake disc 1 before and after transfer. For example, in an example where the angle formed by the line connecting the center of the first deburring wheel 2213 of the first dressing mechanism 221, the axis of the rotating shaft 242, and the center of the support ring 22253 of the second dressing mechanism 222 is 180°, the transfer mechanism 24 may clamp the brake disc 1 and rotate it clockwise by 180° to transfer it from the first dressing mechanism 221 to the second dressing mechanism 222.
[0121] In one embodiment, a brake positioner is provided on the rotating shaft 242. The brake positioner stops the rotational movement of the second clamping unit 243 and also prevents the second clamping unit 243 from rotating due to external forces when it stops, thereby ensuring the positioning accuracy of the brake disc. In one implementation, the brake positioner may be configured to include a brake actuator and a locking pin. The brake actuator controls the movement of the locking pin to lock it onto the rotating shaft 242, thereby stopping the rotational movement of the second clamping unit 243. The brake actuator may be, for example, a motor.
[0122] In one embodiment, the second clamping unit 243 includes a clamping part 2431 and a telescopic drive structure 2432. The clamping part 2431 is used to clamp the brake disc 1, specifically, it opens and closes radially from the brake disc to clamp the brake disc 1. The telescopic drive structure 2432 is disposed on the rotating shaft 242 and connected to the clamping part 2431, and is used to drive the clamping part 2431 to perform telescopic movement. When the second clamping unit 243 clamps the brake disc 1 and rotates around the rotating shaft 242 to the first dressing mechanism 221 and the second dressing mechanism 222, the telescopic drive structure 2432 can drive the clamping part 2431 to extend to clamp the brake disc 1 and place it at the target position, or the telescopic drive structure 2432 can drive the clamping part 2431 to retract to clamp the brake disc 1 and remove it from the target position. The target position refers to the transfer mechanism 24 in the multi-station grinding equipment for brake discs, such as the first deburring wheel 2213 and the retaining ring 22253.
[0123] Please see Figure 19 and combined Figure 18 ,in, Figure 19 The diagram shown is a structural schematic of the telescopic drive structure in one embodiment of this application, as follows: Figure 18 and Figure 19 As shown, the telescopic drive structure 2432 includes a fixed part 24321, a movable part 24322, a telescopic rod 24323, and a drive cylinder 24324. The fixed part 24321 is connected to a rotating shaft 242. The movable part 24322 is disposed between the fixed part 24321 and the clamping part 2431 to drive the clamping part 2431 to extend and retract. The telescopic rod 24323 is disposed inside the movable part 24322 and connected to the clamping part 2431. The drive cylinder 24324 is disposed inside the fixed part 24321 to drive the telescopic rod 24323 to extend and retract. In this example, both the fixed part 24321 and the movable part 24322 are configured as a housing. The interior of the fixed part 24321 has space for arranging the drive cylinder 24324. The movable part 24322 is sleeved on the outside of the fixed part 24321 and can extend and retract relative to the fixed part 24321. Furthermore, the telescopic rods 24323 can be configured as three parallel rods, with each telescopic rod 24323 having a drive cylinder 24324 and a clamping part 2431 connected to its two ends respectively. While driving the clamping part 2431 to extend and retract, the moving part 24322 can also slide and extend and retract on the fixed part 24321.
[0124] Specifically, the drive cylinder 24324 drives the telescopic rod 24323 to extend, thereby causing the clamping part 2431 to clamp the brake disc 1 and extend, while simultaneously causing the moving part 24322 to extend relative to the fixed part 24321; the drive cylinder 24324 drives the telescopic rod 24323 to retract, thereby causing the clamping part 2431 to clamp the brake disc 1 and retract, while simultaneously causing the moving part 24322 to retract relative to the fixed part 24321.
[0125] In one embodiment, such as Figure 19 As shown, the clamping part 2431 includes a base plate 24311, a first gripper 24312, and a second gripper 24313. The base plate 24311 is connected to a telescopic rod 24323. The first gripper 24312 and the second gripper 24313 can be translated relative to the base plate 24311 to clamp the outer edge of the brake disc 1 in an openable and closable manner. In one implementation, the clamping part 2431 further includes a gripper opening and closing drive part, which is used to drive the first gripper 24312 and the second gripper 24313 to retract inward or open outward relative to the base plate 24311 through a helical drive or a linear drive to achieve an opening and closing movement.
[0126] In one embodiment, the inner sides of the clamping ends of the first gripper 24312 and the second gripper 24313 are provided with anti-slip strips that can contact the outer edge of the brake disc 1. In some examples, the anti-slip strips are preferably made of a material with a high coefficient of friction and a certain degree of elasticity, such as nitrile rubber, polyurethane, or wear-resistant silicone, to increase the friction with the outer edge of the brake disc during clamping, while also providing cushioning and protection to prevent the brake disc surface from being damaged by the grippers. In some examples, the surface of the anti-slip strips may be designed with fine anti-slip textures or micro-protrusions to further improve anti-slip performance. In some examples, the anti-slip strips may have a replaceable structure, allowing for quick replacement when wear reaches a limit, reducing maintenance costs.
[0127] In one embodiment, such as Figure 19 As shown, the bottom of the clamping ends of the first jaw 24312 and the second jaw 24313 are provided with a support block 24314 for supporting the annular surface of the brake disc 1. In this embodiment, the support block 24314 provides support when the first jaw 24312 and the second jaw 24313 clamp the brake disc to prevent the brake disc from slipping. In some examples, the support block 24314 can be fixed to the bottom of the clamping end by screws or pins.
[0128] In one embodiment, the clamping length of the first gripper 24312 and the second gripper 24313 is greater than the radius of the brake disc 1. The clamping length refers to the vertical projection distance between the first gripper 24312 and the second gripper 24313. In this embodiment, setting the clamping length to be greater than the radius of the brake disc 1 ensures stable clamping of the brake disc 1.
[0129] In one embodiment, such as Figure 18As shown, the transfer mechanism 24 further includes a rotary drive unit 244 and a lifting drive unit 245. The rotary drive unit 244 is disposed within the transport base 241 and is used to drive the second clamping unit 243 to rotate around the rotating shaft 242. The lifting drive unit 245 is disposed side by side with the rotary drive unit 244 and is used to drive the second clamping unit 243 to perform lifting movements. In one implementation, the transport base 241 has a space inside to accommodate the rotary drive unit 244 and the lifting drive unit 245, and has a protective housing on the outside. It should be noted that... Figure 18 The housing is omitted to show the internal structure of the carrier. Specifically, in Figure 18 In the example shown, the rotary drive unit 244 is positioned in the middle of the carrier 241, and its output shaft is connected to the rotating shaft 242; two lifting drive units 245 are configured and located on both sides of the rotary drive unit 244, for uniformly lifting the second clamping unit 243. In some examples, the rotary drive unit 244 is configured as a rotary cylinder, and the lifting drive unit 245 is configured as a lifting cylinder.
[0130] In one embodiment, such as Figure 18 As shown, a cable chain groove 246 and a bidirectional cable chain 247 disposed within the cable chain groove 246 are provided above the transport base 241. One end of the bidirectional cable chain 247 is connected to the rotating shaft 242, and the other end is connected to the tail end of the fixing part 24321. In one example, the cable chain groove 246 is configured as a circular groove between the second clamping unit 243 and the transport base 241 to provide accommodating space for the bidirectional cable chain 247. Of course, in some other examples, it can also be configured as a U-shaped structure, and the width and depth of the groove can be designed according to the bidirectional cable chain 247. In this embodiment, the rotation drive unit 244 drives the rotating shaft 242 to rotate, at which time the bidirectional cable chain 247 drives the fixing part 24321 to rotate clockwise or counterclockwise around the rotating shaft 242.
[0131] The following combination Figure 18 and Figure 19 The process of transferring the brake disc 1 using the transfer mechanism 24 of this application is described in detail.
[0132] First, the second clamping unit 243 of the transfer mechanism 24 clamps the horizontally placed brake disc. Driven by the rotation drive unit 244, it rotates to a position facing the first dressing mechanism 221. Driven by the lifting drive unit 245, the second clamping unit 24 is raised and lowered so that the height of the clamped brake disc is flush with the first deburring wheel 2213. Then, driven by the telescopic drive structure 2432, the second clamping unit 243 extends the clamping part 2431 to clamp the brake disc 1 and place it on the first deburring wheel 2213. The first jaw 24312 and the second jaw 24313 open under the drive of the jaw opening and closing drive unit to release the brake disc onto the first deburring wheel 2213, thereby realizing the transfer of the brake disc to the first dressing mechanism 221. The transfer mechanism 24 can repeat the above operation to realize the transfer of the brake disc between two positions or two components under the drive of the telescopic drive structure 2432, the rotary drive unit 244, the lifting drive unit 245, and the gripper opening and closing drive unit, respectively.
[0133] In one embodiment, such as Figure 2 and Figure 3 As shown, the multi-station brake disc grinding equipment further includes a loading conveyor mechanism 26 and a unloading conveyor mechanism 27 connected to the base 21 for loading and unloading the brake discs respectively. The loading conveyor mechanism 26 and the unloading conveyor mechanism 27 are inclined relative to the base 21 in accordance with the transfer mechanism 24. In this embodiment, the transfer mechanism 24 is also used to transfer the brake disc to be ground from the loading conveyor mechanism 26 to the first dressing mechanism 221, and to transfer the brake disc that has completed the outer edge grinding and chamfering operations from the flipping device described in a later embodiment to the unloading conveyor mechanism 27. The loading conveyor mechanism 26 and the unloading conveyor mechanism 27 can have the same configuration. The following description uses the loading conveyor mechanism 26 as an example in the embodiment.
[0134] Please see Figure 20 The image shown is a schematic diagram of the feeding and conveying mechanism in one embodiment of this application. Figure 20 As shown, the feeding and conveying mechanism 26 includes a conveying platform 261, a plurality of first bearing structures 262 and a plurality of second bearing structures 263.
[0135] In one embodiment, the conveyor stage 261 is connected to the base 21 and has an internal cavity 2611. In one example, such as Figure 2 and Figure 3The conveyor table 261 is connected to the base 21 at a certain angle, which can be determined according to the extension direction of the transfer mechanism 24. In one example, the conveyor table 261 is configured as a hollow cuboid structure, the hollow portion forming the cavity 2611 to house the plurality of second bearing structures 263. In some examples, the conveyor table 261 can be configured as fixed to accommodate the relatively fixed scenario of the brake disc multi-station grinding equipment 2, or configured as sliding to facilitate operator movement.
[0136] In one embodiment, such as Figure 20 As shown, multiple first supporting structures 262 are fixedly straddling the conveyor table 261 to support multiple vertically placed brake discs 1. Each first supporting structure 262 has a clearance space in the middle, and there is a preset interval between each first supporting structure 262. Figure 20 In the illustrated implementation, each first support structure 262 is configured to include two corresponding first support boxes respectively disposed on both sides of the support platform 261. The width of the first support box matches the width of the brake disc 1, allowing the brake disc 1 to be placed vertically within the first support box. This embodiment conveys vertically placed brake discs, which, compared to the method of conveying horizontally placed brake discs in related technologies, increases the number of brake discs conveyed per unit area, thus improving the feeding and conveying efficiency. In some examples, the number of first support structures 262 is configured to be 10.
[0137] In one embodiment, the first support structure 262 near the base 21 is flip-up to switch the supported brake disc 1 between a horizontal and vertical placement state. See also... Figure 21 and combined Figure 20 ,in, Figure 21 This diagram illustrates a first supporting structure flipped into an upright position in one embodiment of this application. In one implementation, the first supporting structure 262 may be connected to a flipping motor to move along... Figure 20 The arrow indicated by the dashed line rotates 90° clockwise or counterclockwise. Specifically, the first load-bearing structure 262 is in... Figure 21 In the vertical configuration shown, the first supporting structure 262 can support a vertically placed brake disc and transport the brake disc toward the first end. Figure 20 The horizontal position shown facilitates the transfer of the brake disc by the first gripper 24312 and the second gripper 24313 of the transfer mechanism 24.
[0138] In one embodiment, such as Figure 20As shown, multiple second support structures 263 are movably disposed within the cavity. In one example, the second support structure 263 is configured to include a second support box disposed within the cavity 2611. The width of the second support box is equal to the width of the first support box, and its length is not greater than the length of the clearance space, so that the second support box can rise from the clearance space to support and load the brake disc 1 within the first support box. Further, the spacing between each of the second support structures 263 is equal to the preset interval between the first support structures 262, so that when the second support structure 263 rises from the clearance space, it can transfer all the brake discs loaded in the first support structure 262 into the second support box.
[0139] In one embodiment, the plurality of second support structures 263 may be fixed to a movable plate, such that the plurality of second support structures 263 may simultaneously actuate within the cavity 2611 to support the brake disc 1 in the first support structure 262. In some examples, the number of second support structures 263 is configured to be nine.
[0140] In one embodiment, the feeding and conveying mechanism 26 further includes a loading and unloading lifting drive structure for driving the plurality of second bearing structures 263 to perform lifting and lowering movements, and a loading and unloading lateral drive structure for driving the plurality of second bearing structures 263 to move laterally. That is, the plurality of second bearing structures 263 can perform lateral and lifting movements within the cavity 2611. The specific structures of the loading and unloading lifting drive structure and the loading and unloading lateral drive structure can be referred to the description in the foregoing embodiments, and will not be repeated here, as long as they can enable the second bearing structures 263 to perform lateral and lifting movements.
[0141] In one embodiment, the second support structure 263 is used to rise and support the first support structure 262 located at the first end (left end) when it is empty, and drive the brake disc 1 to move laterally toward the first end by the predetermined interval distance, and after filling the empty space of the first support structure 262 at the first end, it descends again and moves laterally to the second end (right end) of the cavity for the next filling.
[0142] Specifically, ten first support structures 262 support ten brake discs 1. The transfer mechanism 24 removes the brake discs 1 near the base 21 and transfers them to the first trimming mechanism 23. Then, the first support structure 262 at the first end of the feeding conveyor mechanism 26 is empty. At this time, the second support structure 263, driven by the loading and unloading lifting drive structure, pushes the remaining nine brake discs from the first support structure 262 and moves towards the first end until it aligns with the first support structure 262, driven by the loading and unloading lateral drive structure. It then descends to load the nine brake discs onto the first support structure 262, filling the gap in the first support structure 262 at the first end, while simultaneously making the first support structure 262 at the second end empty. Next, the first support structure 262 at the first end flips over to... Figure 20 In the horizontal position shown, the transfer mechanism 24 can clamp and remove the brake disc at the first end and transfer the brake disc to the first deburring wheel 2213. At the same time, the brake disc can be manually loaded onto the first bearing structure 262 at the second end. The second bearing structure 263 repeats the above actions to feed the brake disc, and the transfer mechanism 24 continuously transfers the brake disc to achieve feeding.
[0143] In one embodiment, such as Figure 2 and Figure 3 As shown, the outer edge grinding mechanism 23 is disposed in the pretreatment area 212 and located on the first side of the pretreatment mechanism 22, and is used to perform outer edge grinding and chamfering operations on the brake disc that has completed the toroidal grinding operation. Figure 3 As shown, the outer edge grinding mechanism 23 includes an outer edge grinding device 231, a flipping device 232, and a conveying device 233. The flipping device 232 is disposed near the outer edge grinding device 231 to switch the brake disc between a horizontal placement state and a vertical placement state. The conveying device 233 is straddling the flipping device 232 to convey the vertically placed brake disc.
[0144] Please see Figure 22 and Figure 23 ,in, Figure 22 The diagram shown is a schematic representation of the flipping device before flipping in one embodiment of this application. Figure 23 This is a schematic diagram of the flipping device after flipping in one embodiment of this application. The transfer mechanism 24 holds the horizontally placed brake disc 1, which has undergone deburring and inner edge grinding of the second annular surface by the second dressing mechanism 222, and places it horizontally on the flipping device 232 to form a... Figure 22 As shown in the diagram, the flipping device 232 then rotates 90° clockwise to present the desired state. Figure 23The state shown allows the brake disc to be changed from a horizontal to a vertical placement, and then the transport device 233 transports the brake disc to the toroidal grinding mechanism 25 for toroidal grinding. Alternatively, after the brake disc has undergone outer edge grinding and chamfering operations by the outer edge grinding device 231, the transport device 233 transports the vertically placed brake disc to the tilting device 232, which rotates 90° counterclockwise. Figure 22 The state transition shown is to Figure 21 As shown in the diagram, the brake disc changes from a vertical to a horizontal position. Subsequently, the transfer mechanism 24 can transfer the brake disc to the unloading conveyor 27 for unloading.
[0145] In one embodiment, such as Figure 22 and Figure 23 As shown, the flipping device 232 includes a flipping base 2321, a flipping frame 2322, and a flipping drive unit 2323. The flipping base 2321 is disposed on the base 21 and has a flipping platform 2324. The flipping frame 2322 is used to support the brake disc 1 and is rotatably connected to the flipping platform 2324 through a flipping shaft 2325. The flipping drive unit 2323 is disposed on the flipping platform 2324 and is used to drive the flipping frame 2322 to rotate around the flipping shaft 2325, so as to drive the brake disc 1 to switch between a horizontal placement state and a vertical placement state.
[0146] In one embodiment, the tilting platform 2324 is a horizontally arranged platform above the tilting base 2321, used to mount the tilting frame 2322, the tilting drive unit 2323, the tilting shaft 2325, and to support the brake disc 1. In one embodiment, the tilting frame 2322 is a frame structure located at the bottom of the brake disc 1, such as... Figure 22 and Figure 23 As shown, one side of the tilting frame 2322 can be connected to the tilting shaft 2325 via a bearing assembly to achieve a stable tilting action.
[0147] In one embodiment, such as Figure 22 and Figure 23 As shown, the tilting platform 2324 is provided with a stop 2326 to prevent the brake disc 1 from falling. In one example, the stop 2326 is fixedly connected to the right end of the tilting platform 2324, and the brake disc 1 is tilted by the tilting frame 2322 to... Figure 23 In the vertical placement state shown, the two annular surfaces of the brake disc 1 are clamped by the flipping frame 2322 and the blocking part 2326 respectively to confine it to the vertical placement state.
[0148] Please see Figure 24 The image shown is a schematic diagram of the transport device in one embodiment of this application. Figure 24As shown, the conveying device 233 includes a mounting frame 2331, a first clamping unit 2332, a lifting drive unit 2333, and a longitudinal movement drive unit. The first clamping unit 2332 is disposed on the lower side of the mounting frame 2331 and can be opened and closed to clamp the vertically placed brake disc 1. The lifting drive unit 2333 is connected to the first clamping unit 2332 and is used to drive the first clamping unit 2332 to move up and down relative to the mounting frame 2331. The longitudinal movement drive unit is used to drive the first clamping unit 2332 to move longitudinally to transfer the brake disc 1 located on the flipping device 232 to the rotating mechanism of the toroidal grinding mechanism 25 described in the subsequent embodiment for toroidal grinding operation, or to transfer the brake disc 1 located on the rotating mechanism that has completed the outer edge grinding operation and the chamfering operation to the flipping device 232.
[0149] In one embodiment, such as Figure 24 As shown, the mounting bracket 2331 serves as the main support structure of the handling device 233, supporting the first clamping unit 2332 and providing guidance and mounting reference for the lifting drive unit 2333 and the longitudinal movement drive unit. In one example, the mounting bracket 2331 adopts a rectangular frame structure, which may be made of high-strength steel or aluminum alloy, and the first clamping unit 2332 is suspended on the lower side of the mounting bracket 2331.
[0150] In one embodiment, the first clamping unit 2332 is disposed towards the distal end for clamping the brake disc on the rotating mechanism or flipping device 232. In one implementation, the first clamping unit 2332 may be configured to include a first clamping seat, a first clamping member, and a second clamping member. The first clamping seat is connected to the lower end of the lifting drive unit 2333, and the first clamping member and the second clamping member are disposed on opposite sides of the first clamping seat for opening and closing clamping the outer edge 11 of the brake disc 1.
[0151] In one embodiment, the first clamping unit 2332 may further include a first clamping member driving structure for driving at least one of the first and second clamping members to move to adjust the clamping distance between the two clamping members. In some examples, the first clamping member driving structure may be configured to include a lead screw and a driving source, the lead screw being disposed along the length direction of the first clamping seat and associated with at least one of the first and second clamping members, the driving source being used to drive the lead screw to rotate so that the associated at least one clamping member moves along the length direction of the first clamping seat. In other examples, the first clamping member driving structure may be configured to include a bidirectional lead screw and a driving source, the bidirectional lead screw being disposed along the length direction of the first clamping seat and associated with the first and second clamping members, the driving source being used to drive the bidirectional lead screw to rotate so that the first and second clamping members move towards each other or away from each other along the length direction of the first clamping seat. The first clamping member driving structure is not limited to this, and may also employ a telescopic rod and a driving cylinder or a driving hydraulic cylinder, etc.
[0152] In one embodiment, the first and second clamping members each have an arc-shaped groove on the side facing the brake disc. The curvature of the arc-shaped groove conforms to the outer edge 11 of the brake disc 1 so that the brake disc 1 can engage with the arc-shaped groove. In this embodiment, the arc-shaped groove provides a geometric fit with the outer edge 11 of the brake disc 1, allowing the brake disc 1 to be automatically guided into place when inserted into the first clamping unit; furthermore, the arc-shaped structure of the arc-shaped groove can circumferentially cover the brake disc, thereby effectively preventing the brake disc from sliding or shifting during transport. Furthermore, the arc-shaped groove allows the brake disc 1 to form surface contact with each clamping member, dispersing the clamping force and thus avoiding clamping damage to the brake disc 1.
[0153] In one embodiment, the lifting drive unit 2333 is configured to include a lifting rod and a lifting movement drive unit. The lifting rod is vertically inserted through the mounting frame 2331 and connected to the first clamping unit 2332. The lifting movement drive unit is used to drive the lifting rod to perform telescopic movement to drive the first clamping unit 2332 to move up and down.
[0154] In one embodiment, the longitudinal movement drive unit is configured to include a longitudinal movement guide rail disposed on the mounting bracket 2331, a longitudinal movement slider connecting the longitudinal movement guide rail and the lifting drive unit 2333, and a longitudinal movement drive motor for driving the longitudinal movement slider to move longitudinally along the longitudinal movement guide rail to simultaneously drive the lifting drive unit 2333 and the first clamping unit 2332 to move longitudinally. When the longitudinal movement drive motor drives the lifting drive unit 2333 and the first clamping unit 2332 to move longitudinally from the proximal end to the distal end, the brake disc 1 located on the flipping device 232 can be transferred to the rotating mechanism for toroidal grinding. When the longitudinal movement drive motor drives the lifting drive unit 2333 and the first clamping unit 2332 to move longitudinally from the distal end to the proximal end, the brake disc 1 located on the rotating mechanism, which has completed the outer edge grinding and chamfering operations, can be transferred to the flipping device 232.
[0155] In one embodiment, the outer edge grinding device 231 is used to perform outer edge grinding and chamfering operations on the vertically placed brake disc. See also... Figure 25 The image shown is a schematic diagram of the outer edge grinding device in one embodiment of this application.
[0156] In one embodiment, such as Figure 25 As shown, the outer edge grinding mechanism 23 also includes a forward / backward drive device 232 disposed on the base 21, which is used to drive the outer edge grinding device 231 to move longitudinally. In some examples, the forward / backward drive device 232 may include a longitudinal guide rail, a longitudinal moving lead screw, and a longitudinal moving drive motor disposed on the base 21, wherein the longitudinal moving drive motor drives the longitudinal moving lead screw to rotate, thereby driving the outer edge grinding device 231 to move on the longitudinal guide rail.
[0157] In one embodiment, such as Figure 25 As shown, the outer edge grinding mechanism 22 further includes a lateral drive device 233 disposed above the forward / reverse drive device 232 for driving the outer edge grinding device 231 to move laterally to approach the brake disc. In some examples, the lateral drive device 233 may include a lateral guide rail, a lateral movement screw, and a lateral movement drive motor disposed on the forward / reverse drive device 232, wherein the lateral movement drive motor drives the lateral movement screw to rotate, thereby driving the outer edge grinding device 231 to move on the lateral guide rail.
[0158] In one embodiment, such as Figure 25As shown, the outer edge grinding device 231 includes an outer edge grinding machine base 2311, a first outer edge grinding spindle 2312, and a second outer edge grinding spindle 2313. The first outer edge grinding spindle 2312 is fixedly mounted on the outer edge grinding machine base 2311, and the second outer edge grinding spindle 2313 is vertically and flexibly mounted on the upper side of the first outer edge grinding spindle 2312. Specifically, the outer edge grinding machine base 2311 is located above the transverse drive device 233, the first outer edge grinding spindle 2312 is mounted on the outer edge grinding machine base 2311, and the second outer edge grinding spindle 2313 is mounted on the upper side of the first outer edge grinding spindle 2312. That is, the first outer edge grinding spindle 2312 and the second outer edge grinding spindle 2313, driven by the outer edge grinding machine base 2311, approach the outer edge 11 of the brake disc 1 through the transverse drive device 233, and perform feed grinding on the outer edge 11 through the forward and backward drive device 232.
[0159] In one embodiment, such as Figure 25 As shown, the outer edge grinding device 231 also includes a lifting drive structure 2314, which is disposed on the outer edge grinding machine base 2311 and is used to drive the second outer edge grinding spindle 2313 to perform lifting and lowering movements to adjust the grinding amount. It should be understood that by controlling the lifting and lowering of the second outer edge grinding spindle 2313, the contact depth between the second outer edge grinding spindle 2313 and the brake disc 1 can be adjusted. For example, if the lifting drive structure 2314 controls the second outer edge grinding spindle 2313 to move downwards, the second outer edge grinding spindle 2313 can make deeper contact with the outer edge 11 of the brake disc 1, thereby increasing the grinding amount; if the lifting drive structure 2314 controls the second outer edge grinding spindle 2313 to move upwards, the contact depth between the second outer edge grinding spindle 2313 and the outer edge 11 of the brake disc 1 can be shallower, thereby reducing the grinding amount.
[0160] In one embodiment, such as Figure 25 As shown, the proximal end of the first outer edge grinding spindle 2312 has a first grinding wheel 23121, and the proximal end of the second outer edge grinding spindle 2313 has a second grinding wheel 23131. The first outer edge grinding spindle 2312 and the second outer edge grinding spindle 2313 may have the same configuration.
[0161] In one embodiment, the first grinding wheel 23121 and the second grinding wheel 23131 are staggered. This staggered arrangement means that the first grinding wheel 23121 and the second grinding wheel 23131 are not completely aligned in space, so that the contact positions of their rims on the outer edge 11 of the brake disc 1 are offset and spaced apart. This avoids repeated grinding at the same position on the outer edge 11 by the first grinding wheel 23121 and the second grinding wheel 23131. The collaborative processing of the two grinding wheels expands the coverage of a single grinding operation, thereby improving grinding efficiency.
[0162] Please see Figures 26 to 28 The diagrams shown are schematic representations of the outer edge grinding operation performed using a first grinding wheel and a second grinding wheel in one embodiment of this application. To facilitate illustrating the outer edge grinding process and the relative positions of the first and second grinding wheels, Figures 26 to 28 All are presented as top views. It should be noted here that... Figures 26 to 28 The relative positions of the first grinding wheel 23121 and the second grinding wheel 23131 are only schematically illustrated and should not be construed as limiting this application. Figures 26 to 28 In the example shown, the first grinding wheel 23121 and the second grinding wheel 23131 are connected to each other in the longitudinal direction. However, in some other examples, the first grinding wheel 23121 and the second grinding wheel 23131 may partially overlap or have a certain gap in the longitudinal direction, depending on the actual grinding requirements.
[0163] In one embodiment, such as Figures 26 to 28 As shown, the first grinding wheel 23121 and the second grinding wheel 23131 are misaligned, so that the first grinding wheel 23121 first grinds the outer edge 11 to form a first step structure A1 by moving laterally, and the second grinding wheel 23131 grinds the outer edge 11 to form a second step structure A2 that connects with the first step structure A1 by moving downward. The first grinding wheel 23121 and the second grinding wheel 23131 grind the first step structure A1 and the second step structure A2 in sequence by moving longitudinally to complete the outer edge grinding operation.
[0164] Specifically, such as Figure 26 As shown, the transverse drive device 233 drives the first grinding wheel 23121 and the second grinding wheel 23131 along... Figure 26 The arrow in the image approaches the outer edge 11, causing the first grinding wheel 23121 to perform the first grinding on the outer edge 11 to form the first step structure A1, thus presenting... Figure 27The state shown. Next, the second grinding wheel 23131, driven by the lifting drive structure 2314, descends to a preset position determined according to the grinding amount. Simultaneously, the first grinding wheel 23121 and the second grinding wheel 23131, driven by the forward and backward drive device 232, move along... Figure 27 The second grinding wheel 23131 moves in the direction of the arrow to contact the outer edge 11 for a second grinding, thereby forming... Figure 28 The second step structure A2 is shown. Then, the first grinding wheel 23121 and the second grinding wheel 23131 move along the path driven by the forward and backward drive device 232. Figure 28 Move in the direction of the arrow until the grinding operation is completed on the outer edge 11.
[0165] The following combination Figures 25 to 28 The process of performing edge grinding and chamfering operations using the edge grinding mechanism 23 of this application is described in detail.
[0166] First, the first grinding wheel 23121 and the second grinding wheel 23131 of the outer edge grinding device 231 are driven by the transverse drive device 233 along the edge... Figure 26 The arrow in the image approaches the outer edge 11, causing the first grinding wheel 23121 to perform the first grinding on the outer edge 11 to form the first step structure A1, thus presenting... Figure 27 The state shown. Next, within a preset time interval, the second grinding wheel 23131 descends to a preset position determined according to the grinding amount under the drive of the lifting drive structure 2314. Simultaneously, the first grinding wheel 23121 and the second grinding wheel 23131 move along the path driven by the forward and backward drive device 232. Figure 27 The second grinding wheel 23131 moves in the direction of the arrow to contact the outer edge 11 for a second grinding, thereby forming... Figure 28 The second step structure A2 is shown. Then, the first grinding wheel 23121 and the second grinding wheel 23131 move along the path driven by the forward and backward drive device 232. Figure 28 Move in the direction of the arrow until the outer edge is ground. After the outer edge grinding is completed, the second grinding wheel 23131 can be used to chamfer the two outer rings of the brake disc 1.
[0167] In one embodiment, such as Figure 3 As shown, the annular grinding mechanism 25 is disposed in the annular processing area 211, including three annular grinding devices and a rotating mechanism 254. The three annular grinding devices are used to perform grinding operations on the first and second annular surfaces of the vertically placed brake disc from the conveying device 233. The rotating mechanism 254 is disposed between the three annular grinding devices and is used to rotate the brake disc that has completed the annular grinding operation to the outer edge grinding device 231 for transfer.
[0168] It should be noted here that, for ease of description and explanation, such as Figure 3 As shown, in subsequent embodiments, the three annular grinding devices are referred to sequentially in a counterclockwise direction as the first annular grinding device 251, the second annular grinding device 252, and the third annular grinding device 253. Specifically, after the transport device 233 transfers the brake disc 1, which is placed vertically on the flipping device 232, to the rotating mechanism 254, the rotating mechanism 254 rotates counterclockwise by 90° in sequence to perform annular grinding using the first annular grinding device 251, the second annular grinding device 252, and the third annular grinding device 253, respectively. After the annular grinding operation is completed, the rotating mechanism 254 rotates clockwise by 270° to transfer the brake disc to the outer edge grinding device 231 for outer edge grinding and chamfering operations.
[0169] In one embodiment, the grinding time of the first toroidal grinding device 251, or the second toroidal grinding device 252, or the third toroidal grinding device 253 is one-third of the grinding time of the outer edge grinding device 231. For example, if the outer edge grinding device 231 performs outer edge grinding for 60 seconds, then the toroidal grinding time of the first toroidal grinding device 251, the second toroidal grinding device 252, and the third toroidal grinding device 253 is 20 seconds each. In other words, the 60 seconds required for the outer edge grinding operation is exactly equal to the total time of 20 seconds for each of the three annular grinding devices. By using the rotating mechanism 254 to drive the brake disc to rotate between the outer edge grinding device 221 and the first annular grinding device 251, the second annular grinding device 252, and the third annular grinding device 253, the brake disc can complete the outer edge grinding operation and the chamfering operation in parallel while completing the annular grinding operation. This helps to improve the efficiency of the overall processing cycle and realize the continuous automated grinding of the brake disc.
[0170] In one embodiment, the grinding amount of the first annular grinding device 251, or the second annular grinding device 252, or the third annular grinding device 253 on the brake disc is 1 / 3 of the total annular grinding amount. For example, when the total annular grinding amount of the brake disc 1 is 0.3 mm when the annular grinding operation is completed, the grinding amount of each of the above-mentioned annular grinding devices on the brake disc is 0.1 mm. In this way, each annular grinding device only needs to complete 1 / 3 of the total grinding amount, which helps to achieve the above-mentioned processing cycle while reducing the workload of each annular grinding device, thereby extending the service life of each annular grinding device.
[0171] In one embodiment, a first annular grinding device 251, a second annular grinding device 252, and a third annular grinding device 253 are arranged around the annular machining area 211. Figure 3In the example shown, the first toroidal grinding device 251, the second toroidal grinding device 252, and the third toroidal grinding device 253 are arranged in a fan shape around the rotating mechanism 254. The included angles between the second toroidal grinding device 252 and the first toroidal grinding device 251, and between the second toroidal grinding device 252 and the third toroidal grinding device 253, are both 90°. Furthermore, the included angle between the outer edge grinding device 231 and each adjacent grinding device among the three toroidal grinding devices is 90°. In this embodiment, the included angles between each grinding device are 90° to form a cross-shaped layout, thereby facilitating the cooperation between the grinding devices and the rotating mechanism 254, achieving automated rotation and alignment of the brake disc.
[0172] The first annular grinding device 251, the second annular grinding device 252, and the third annular grinding device 253 have the same configuration. The structure of each annular grinding device will be described below using the first annular grinding device 251 as an example. Please refer to... Figure 29 The image shown is a schematic diagram of the structure of the first annular grinding apparatus in one embodiment of this application. Figure 29 As shown, the toroidal grinding mechanism 25 further includes a first driving device 255 and a second driving device 256. The first driving device 255 is disposed on the base 21 and is used to drive the first toroidal grinding device 251 to approach the rotating mechanism 254. The second driving device 256 is disposed above the first driving device 255 and is used to drive the first toroidal grinding device 251 to approach the toroidal surface 13 of the brake disc for grinding. The specific structures of the first driving device 255 and the second driving device 256 can be found in the description of the forward and backward driving device 232 and the lateral driving device 233 in the previous embodiments, and will not be repeated here.
[0173] In one embodiment, such as Figure 29 As shown, the first annular grinding device 251 includes a first annular grinding spindle 2511 and a second annular grinding spindle 2512. The first annular grinding spindle 2511 and the second annular grinding spindle 2512 are arranged side by side above the second drive device 256 and can move towards each other along the second drive device 256 to grind the annular surfaces 13 on opposite sides of the brake disc respectively. Figure 29 In the example shown, both the first toroidal grinding spindle 2511 and the second toroidal grinding spindle 2512 have a grinding wheel. For ease of description, the grinding wheel of the first toroidal grinding spindle 2511 is referred to as the first toroidal grinding wheel 25111, and the grinding wheel of the second toroidal grinding spindle 2512 is referred to as the second toroidal grinding wheel 25121. The first toroidal grinding wheel 25111 and the second toroidal grinding wheel 25121 will not be described again in the following references.
[0174] Specifically, in this embodiment, the brake disc is rotated by the rotating mechanism 254 to a position between the first annular grinding wheel 25111 and the second annular grinding wheel 25121. The two annular grinding wheels move towards each other a certain distance under the drive of the second driving device 256 (this distance is determined according to the grinding amount). Then, the two annular grinding wheels approach the rotating mechanism 254 under the drive of the first driving device 255, thereby performing annular grinding on the brake disc 1.
[0175] Please see Figure 30 The image shown is a partially enlarged schematic diagram of the first annular grinding device in one embodiment of this application. Figure 30 As shown, a liftable thickness detection device 257 for detecting the thickness of the brake disc 1 to determine the feed rate is provided between the first annular grinding spindle 2511 and the second annular grinding spindle 2512. Figure 30 In the illustrated embodiment, the thickness detection device 257 is configured to include a lifting mechanism 2571 and a detection head assembly 2572. The detection head assembly 2572 is used to detect the thickness of the brake disc 1. The lifting mechanism 2571 is used to drive the detection head assembly 2572 to move up and down vertically, so that the detection head assembly 2572 descends to both sides of the brake disc 1 when detection is needed, and rises to a position that does not interfere with the rotation of the rotating mechanism 254 and the grinding operation when detection is not needed. In some examples, the lifting mechanism 2571 may be configured to achieve the lifting movement by means of electric lead screw lifting, cylinder drive, or servo motor drive.
[0176] Please see Figure 31 The diagram shows a schematic representation of the rotating mechanism in one embodiment of this application. Figure 31 As shown, the rotating mechanism 254 includes a rotating seat 2541, a rotating support 2542, and a shaft 2543.
[0177] In one embodiment, the rotating base 2541 is disposed on the base 21 and is used to support the vertically placed brake disc 1, having a rotating platform 25411 on it. In this embodiment, the rotating base 2541 is fixedly disposed on the base 21, and may be integrally formed and connected to the base 21, for example. In some examples, to achieve stable support for components such as the brake disc 1 and the rotating bracket 2542, the rotating base 2541 may be configured to be made of materials such as cast iron or stainless steel. Figure 31 In the example shown, the swivel base 2541 is configured as a cylinder to minimize its footprint.
[0178] In one embodiment, the rotating table 25411 can rotate relative to the rotating base 2541 to drive the rotating support 2542 thereon to rotate, thereby causing the brake disc 1 to rotate between the outer edge grinding device 231, the first annular grinding device 251, the second annular grinding device 252, and the third annular grinding device 253. In some examples, the rotating table 25411 is provided with an angle encoder to accurately set the rotation angle of the rotating mechanism. In some examples, the rotating table 25411 is provided with a positioning device so that it can stop rotating the brake disc 1 after it reaches the grinding position, thereby fixing the brake disc 1 in the grinding position for subsequent grinding operations using the outer edge grinding device 231 or any of the annular grinding devices.
[0179] Please see Figure 32 This application is displayed as such. Figure 31 A schematic diagram of the rotating bracket in the illustrated embodiment. Figure 31 and Figure 32 As shown, the rotating support 2542 includes four support arms 25421 disposed on the rotating table 25411, with an included angle of 90° between each adjacent support arm, used to drive the brake disc to rotate between the outer edge grinding device 231, the first annular grinding device 251, the second annular grinding device 252, and the third annular grinding device 253. In this embodiment, the four support arms 25421 are centrally symmetrically arranged on the rotating table 25411 along the axis of the rotating seat 2541. Specifically, under the support of a certain support arm 25421 on the rotating bracket 2542, the rotating bracket 2542 rotates counterclockwise by 90° in sequence under the drive of the rotating table 25411, and completes one-third of the annular grinding operation at the first annular grinding device 251, the second annular grinding device 252, and the third annular grinding device 253 in sequence. After that, the rotating bracket 2542 rotates clockwise by 270° under the drive of the rotating table 25411, and rotates the brake disc that has completed the annular grinding operation to the rear outer edge grinding device 231 to start the outer edge grinding operation and chamfering operation.
[0180] In one embodiment, such as Figure 31 and Figure 32As shown, a shaft 2543 is vertically disposed at one end of each of the support arms 25421, and has a claw portion 25431 that can be opened and closed to fix the inner edge of the brake disc 1. In one example, the claw portion 25431 is configured as a three-claw structure, which is equidistantly arranged around the circumference of the shaft 2543. The end of the claw portion used to fix the inner edge of the brake disc has a clamping surface that fits against the inner edge. The clamping surface may be covered with a rubber sheet to enhance the clamping stability of the brake disc. In some examples, the shaft 2543 may be configured as a hollow structure, with an opening and closing drive structure inside for driving the claw portion 25431 to open and close, so as to drive the claw portion 25431 to retract towards the axis to fix the inner edge of the brake disc.
[0181] In one embodiment, such as Figure 32 As shown, the rotating mechanism 254 further includes a rotating drive device 2544, which is used to drive the brake disc 1 to rotate around its center. Figure 32 In the illustrated embodiment, the rotary drive device 2544 is disposed on the back side of the support arm 25421 (the side opposite to the side where the shaft 2543 is disposed). For an example of one rotary drive device 2544, please refer to [link to example document]. Figure 33 ,in, Figure 33 This application is displayed. Figure 32 A schematic diagram of the rotary drive device in the illustrated embodiment. Figure 33 As shown, the rotary drive device 2544 includes a rotary drive motor 25441 disposed at the other end of the support arm 25421, and a conveyor belt 25443 connecting the output shaft 25442 of the rotary drive motor 25441 and the shaft body 2543. The rotary drive motor 25441 transmits power to the shaft body 2543 through the conveyor belt 25443, thereby causing the shaft body 2543 to drive the brake disc to rotate.
[0182] The following combination Figures 29 to 33 The process of performing toroidal grinding operations using the toroidal grinding mechanism 25 of this application is described in detail.
[0183] The aforementioned transfer mechanism 24 can transfer the brake disc, which has undergone inner edge grinding and deburring, to the tilting device 232, which changes the brake disc from a horizontal to a vertical position. Then, the transport device 233 transfers the vertically placed brake disc to the shaft 2543 of the rotating mechanism 254. Subsequently, the rotating support 2542 rotates 90° counterclockwise under the drive of the rotating table 25411, rotating the brake disc, which has undergone outer edge grinding, to the first annular grinding device 251. Next, the thickness detection device 257 descends to both sides of the brake disc 1 to detect the thickness of the brake disc to determine the feed rate. After the detection is completed, the thickness detection device 257 rises to a position that does not interfere with the grinding operation.
[0184] The first toroidal grinding wheel 25111 and the second toroidal grinding wheel 25121 move towards each other under the drive of the second drive device 256, and then approach the rotating mechanism 254 under the drive of the first drive device 255, thereby performing one-third of the overall toroidal grinding operation on the brake disc 1. Afterwards, the rotating support 2542 rotates 90° counterclockwise under the drive of the rotating table 25411 to rotate the brake disc to the second toroidal grinding device 252. After completing two-thirds of the overall toroidal grinding operation, the rotating support 2542 rotates 90° counterclockwise again to rotate the brake disc to the third toroidal grinding device 253 to complete the remaining one-third of the toroidal grinding operation. Subsequently, the rotating support 2542 rotates 270° clockwise under the drive of the rotating table 25411 to perform outer edge grinding and chamfering operations on the brake disc after the toroidal grinding operation using the outer edge grinding device 231. Then, the conveying device 233 transfers the brake disc that has completed the above processes to the tilting device 232, which changes the brake disc from a vertical position to a horizontal position. Finally, the transfer mechanism 24 transfers the completed brake disc to the unloading conveying mechanism 27 for unloading.
[0185] The following combination Figures 1 to 33 The process of deburring the first and second annular surfaces, grinding the inner edge, grinding the annular surface, grinding the outer edge, and chamfering the brake disc multi-station grinding equipment 2 provided in this application is described in detail.
[0186] First, the transfer mechanism 24 transfers the brake disc 1 from the feeding conveyor 26 to the first dressing mechanism 221 in the pretreatment area 212, and places it horizontally on the first deburring wheel 2213. Then, the pressing drive structure 22191 of the pressing swing device 2216 drives the mounting structure 22172 to descend, so that the elastic limiting part 22176 is inserted into the hole 121 of the brake disc 1, and the brake disc 1 is pressed between the first deburring wheel 2213 and the swing member 22174, presenting a position where... Figure 4 The state is shown. Then, the first deburring wheel 2213 rotates at high speed under the drive of the first wheel drive structure 2214, and the brake disc 1 rotates in the opposite direction to the first deburring wheel 2213 under the drive of the rotation drive structure 22192. At the same time, the brake disc 1 rotates in the opposite direction to the first deburring wheel 2213 under the drive of the swing drive structure 22173. Figure 12 The first position shown and Figure 13 The device swings between the second position shown until the deburring of the first annular surface is completed.
[0187] After the deburring of the first annular surface is completed, the transfer mechanism 24 transfers the brake disc 1 to the second dressing mechanism 222 and places it horizontally on the brake disc support device 2225, where the outer edge of the brake disc is held by the jaws 22254. Then, the second deburring device 2221 and the inner edge grinding device 2222 operate simultaneously. The first lateral moving structure and the second lateral moving structure can simultaneously drive the deburring assembly 22212 and the inner edge grinding assembly 22222 to move laterally relative to each other, so that the second deburring grinding wheel 22214 and the inner edge grinding wheel 22224 reach above the brake disc 1 respectively. Subsequently, the first lifting structure and the second lifting structure simultaneously drive the deburring assembly 22212 and the inner edge grinding assembly 22222 to descend, so that the second deburring grinding wheel 22214 and the inner edge grinding wheel 22224 contact the second annular surface and the inner edge of the brake disc 1 respectively, until the deburring of the second annular surface and the grinding of the inner edge are completed.
[0188] Subsequently, the transfer mechanism 24 horizontally places the brake disc 1 onto the tilting device 232 to form a... Figure 22 As shown in the diagram, the flipping device 232 then rotates 90° clockwise to present the desired state. Figure 23 The brake disc is positioned so that it changes from a horizontal to a vertical placement. The transport device 233 then moves the brake disc to the claw 25431 of the rotating mechanism 254. The rotating support 2542 rotates 90° counterclockwise under the drive of the rotating table 25411, rotating the brake disc to the first annular grinding device 251. Next, the thickness detection device 257 descends to both sides of the brake disc 1 to detect the thickness of the brake disc and determine the feed rate. After detection, the thickness detection device 257 rises to a position that does not interfere with the grinding operation. The first annular grinding wheel 25111 and the second annular grinding wheel 25121 move towards each other under the drive of the second drive device 256, and then approach the rotating mechanism 254 under the drive of the first drive device 255, thus performing one-third of the overall annular grinding operation on the brake disc 1. Subsequently, the rotating support 2542, driven by the rotating table 25411, rotates 90° counterclockwise again to rotate the brake disc to the second annular grinding device 252. After completing two-thirds of the overall annular grinding operation, the rotating support 2542 rotates 90° counterclockwise again to rotate the brake disc to the third annular grinding device 253 to complete the remaining one-third of the annular grinding operation.
[0189] After the toroidal grinding operation is completed, the rotating mechanism 254 rotates 270° clockwise, transferring the brake disc to the outer edge grinding device 231 for outer edge grinding and chamfering operations. Specifically, the first grinding wheel 23121 and the second grinding wheel 23131 of the outer edge grinding device 231 are driven by the transverse drive device 233 along... Figure 26The arrow in the image approaches the outer edge 11, causing the first grinding wheel 23121 to perform the first grinding on the outer edge 11 to form the first step structure A1, thus presenting... Figure 27 The state shown. Next, within a preset time interval, the second grinding wheel 23131 descends to a preset position determined according to the grinding amount under the drive of the lifting drive structure 2314. Simultaneously, the first grinding wheel 23121 and the second grinding wheel 23131 move along the path driven by the forward and backward drive device 232. Figure 27 The second grinding wheel 23131 moves in the direction of the arrow to contact the outer edge 11 for a second grinding, thereby forming... Figure 28 The second step structure A2 is shown. Then, the first grinding wheel 23121 and the second grinding wheel 23131 move along the path driven by the forward and backward drive device 232. Figure 28 The grinding wheel moves in the direction of the arrow until the outer edge is ground. After the outer edge grinding is completed, the second grinding wheel 23131 can be used to chamfer the two outer rings of the brake disc 1. Then, the transport device 233 transfers the brake disc that has completed the above process to the flipping device 232, which changes the brake disc from a vertical position to a horizontal position. Finally, the transfer mechanism 24 transfers the completed brake disc to the unloading conveyor 27 for unloading.
[0190] In summary, the multi-station brake disc grinding equipment disclosed in this application achieves fully automated processing of brake discs, including deburring, inner edge grinding, toroidal grinding, outer edge grinding, and chamfering, all on a single machine. Through integrated station design, continuous process transfer, and controllable positioning, the multi-station brake disc grinding equipment disclosed in this application significantly improves processing efficiency and grinding accuracy, offering the following beneficial effects:
[0191] First, the equipment has a pre-treatment area and a ring-shaped machining area on the base. By arranging the first dressing mechanism and the second dressing mechanism in sequence in the pre-treatment area, the brake disc can automatically complete the deburring of the first and second ring surfaces before entering the formal grinding. Simultaneously, the inner edge grinding is performed in the second dressing mechanism. This pre-treatment structure that integrates deburring and inner edge grinding not only completely eliminates the error of manual grinding and manual positioning, but also significantly shortens the pre-treatment cycle through the simultaneous operation of two stations, providing a smooth and stable reference surface for subsequent grinding.
[0192] Secondly, by setting up a coordinated linkage structure of the flipping device, the transfer mechanism and the handling device, the automatic flipping and orderly transfer of the brake disc between horizontal and vertical states are realized, so that the brake disc can achieve continuous conversion and precise connection of spatial posture in different grinding stages. This significantly improves the alignment accuracy and cycle synchronization between each grinding station. This application effectively avoids the secondary positioning error and workpiece clamping deviation caused by traditional multi-equipment transfer, and ensures the consistency of processing accuracy.
[0193] Furthermore, through the cooperation of the three equally angularly distributed toroidal grinding devices and the rotary mechanism in the toroidal grinding mechanism, the brake disc can complete the segmented grinding of both sides of the toroidal surface during continuous rotation. The entire grinding process forms a structured rhythm of three-part sequential grinding, which not only realizes multi-process parallel operation, but also greatly improves the efficiency and uniformity of toroidal grinding. Moreover, the rotary mechanism automatically indexes 90° after each third of grinding is completed, which makes the grinding load evenly distributed, significantly reduces thermal deformation and surface stress concentration, and improves the flatness and thickness consistency of the brake disc.
[0194] In addition, the outer edge grinding device adopts a dual-spindle staggered layer grinding structure. The first grinding wheel and the second grinding wheel complete rough grinding and fine grinding of different steps in sequence, and then complete the chamfering operation through longitudinal linkage motion. The design of this outer edge grinding device not only ensures the consistency of the outer edge size and chamfer angle, but also realizes continuous operation from rough grinding, fine grinding to chamfering, avoiding angle deviation and uneven chamfering caused by repeated clamping.
[0195] Finally, through the cyclical control of the transfer mechanism, the entire machine achieves closed-loop automated control of the brake disc's entire process, from loading, pretreatment, flipping, grinding, chamfering, to unloading. The processing sequence between each mechanism is naturally connected, and the action rhythm is coordinated, enabling the equipment to achieve a highly efficient, highly consistent, and low-reliability intelligent production mode. Therefore, this application not only significantly improves the multi-station grinding efficiency and automation level of brake discs, but also effectively ensures grinding accuracy and product consistency through optimized processing sequence and structural synergy, demonstrating significant industrial application value.

Any person skilled in the art can modify or alter the above embodiments without departing from the principles and scope of this application. Therefore, all equivalent modifications or alterations achieved by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
