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 would affect its positioning and clamping during grinding, thus impacting grinding accuracy. Therefore, deburring is usually necessary before grinding the brake disc. 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 overall grinding efficiency. Furthermore, some technologies perform the inner edge grinding, outer edge grinding, and circumferential surface grinding on separate grinding machines, further reducing grinding efficiency. Therefore, how to integrate the deburring process of brake discs with the inner edge, outer edge and annular surface grinding operations into the same processing equipment to improve grinding efficiency is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] 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 problem that the existing brake disc grinding equipment uses manual deburring and cannot perform inner edge, outer edge and annular surface grinding functions, resulting in low grinding efficiency.

[0005] 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 having opposing first and second sides, the first side having an annular surface processing area, and the second side having a pre-treatment area; a transfer robot disposed in the pre-treatment area for switching the brake disc between a vertical and horizontal placement state and transferring the brake disc between the pre-treatment area and the annular surface processing area; a first dressing mechanism disposed in the pre-treatment area and located at the distal end of the transfer robot, including a first deburring device for deburring the first annular surface of the horizontally placed brake disc from the transfer robot; and a second dressing mechanism disposed in the pre-treatment area and located at the distal end of the transfer robot. The proximal end of the transfer robot receives the brake disc after the first deburring operation, including a second deburring device arranged in parallel along the lateral direction for deburring the second annular surface of the horizontally placed brake disc and an inner edge grinding device for grinding the inner edge of the brake disc; an outer edge grinding mechanism, located in the pretreatment area and at the distal end of the transfer robot to receive the brake disc after the second deburring and inner edge grinding operations, includes an outer edge grinding device for grinding the outer edge of the vertically placed brake disc; and an annular grinding mechanism, located in the annular processing area, includes three annular grinding devices for grinding the first and second annular surfaces of the vertically placed brake disc after the outer edge grinding operation, and a rotating mechanism arranged between the three annular grinding devices for transferring the brake disc between the three annular grinding devices and the outer edge grinding device.

[0006] In summary, the multi-station brake disc grinding equipment provided in this application automates the deburring process of the brake disc and improves grinding efficiency by setting a pretreatment area on the base and including a first dressing mechanism for deburring the first annular surface of the brake disc and a second dressing mechanism for deburring the second annular surface and grinding the inner edge within the pretreatment area. Furthermore, by performing the deburring of the second annular surface and the inner edge grinding simultaneously, the processing time of the brake disc is further reduced.

[0007] The multi-station brake disc grinding equipment of this application integrates inner edge grinding, outer edge grinding, and toroidal grinding operations on the same grinding equipment by setting up a second dressing mechanism, an outer edge grinding mechanism, and a toroidal grinding mechanism, thereby further improving the grinding efficiency of the brake disc. Furthermore, by setting up a rotary mechanism for transfer between the three toroidal grinding devices and the outer edge grinding device, this application achieves the connection between the outer edge grinding operation and the toroidal grinding operation, ensuring automated, continuous, assembly-line grinding of the brake disc.

[0042] In view of the technical problems mentioned in the background art, this application discloses a multi-station grinding equipment for brake discs. By setting a pretreatment area on the base, and setting a first dressing mechanism for deburring the first annular surface of the brake disc and a second dressing mechanism for deburring the second annular surface and grinding the inner edge within the pretreatment area, the deburring process of the brake disc is automated, improving grinding efficiency. By performing the deburring of the second annular surface and the inner edge grinding simultaneously, the processing time of the brake disc is further reduced.

[0043] The multi-station brake disc grinding equipment of this application integrates inner edge grinding, outer edge grinding, and toroidal grinding operations on the same grinding equipment by setting up a second dressing mechanism, an outer edge grinding mechanism, and a toroidal grinding mechanism, thereby further improving the grinding efficiency of the brake disc. Furthermore, by setting up a rotary mechanism for transfer between the three toroidal grinding devices and the outer edge grinding device, this application achieves the connection between the outer edge grinding operation and the toroidal grinding operation, ensuring automated, continuous, assembly-line grinding of the brake disc.

[0044] 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 length extension direction 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).

[0045] 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.

[0046] In any embodiment provided in this application, the brake disc refers to a generally flat, annular structure. 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 1 As 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.

[0047] In practical applications, the outer edge 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.

[0048] 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.

[0049] The multi-station grinding equipment for brake discs described in this application is used for grinding brake discs 1. Please refer to... Figure 2 and Figure 3 The images 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 transfer robot 22, a first dressing mechanism 23, a second dressing mechanism 24, an outer edge grinding mechanism 25, and a ring surface grinding mechanism 26.

[0050] 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.

[0051] 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 3As 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.

[0052] 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 26 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 during the toroidal grinding operation. Similarly, the first dressing mechanism 23, the second dressing mechanism 24, and the outer edge grinding mechanism 25 are located in the pre-treatment area 212, and the range of the pre-treatment area 212 is the range occupied by the first dressing mechanism 23, the second dressing mechanism 24, and the outer edge grinding mechanism 25 during the deburring of the first toroidal surface, the deburring of the second toroidal surface, the inner edge grinding operation, and the outer edge grinding operation, respectively.

[0053] 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 23 is disposed in the pre-processing area 211 and located at the far end of the transfer robot 22. In this embodiment, the first trimming mechanism 23 includes a first deburring device 231, which is used to deburr the first annular surface of the horizontally placed brake disc from the transfer robot 22.

[0054] Please see Figure 5 The diagram shows a structural schematic of the deburring device in one embodiment of this application, as shown below. Figure 5As shown, the first deburring device 231 includes a base 2311 and a first deburring grinding wheel 2312. The base 2311 is disposed on the base 21. The axis of the first deburring grinding wheel 2312 is perpendicular to the base 2311 and is used to deburr the first annular surface of the horizontally placed brake disc 1.

[0055] In one embodiment, the base 2311 is used to support the main structure of the first dressing mechanism 23. In some examples, the base 2311 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 2311 has a mounting surface, which can be used to install structures or devices such as the first deburring wheel 2312. Specifically, as... Figure 5 As shown, the first deburring wheel 2312 is connected to the upper end of the first deburring spindle 2310, and the first deburring wheel 2312 is set on the base 2311 by the installation of the first deburring spindle 2310 on the mounting plane.

[0056] In one embodiment, the first deburring spindle 2310 is vertically inserted through the mounting plane, and a drive shaft is fixedly installed at its center. The drive shaft is connected to the center of the first deburring grinding wheel 2312, thereby driving the first deburring grinding wheel 2312 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 2312. In this embodiment, the first deburring grinding wheel 2312 also provides a working platform for grinding the first annular surface.

[0057] In one embodiment, such as Figure 5 As shown, the first deburring device 231 also includes a first grinding wheel drive structure 2313, which is disposed on the other side of the base 2311 and is used to drive the first deburring grinding wheel 2312 to rotate. Specifically, the first grinding wheel drive structure 2313 can drive the transmission shaft to rotate, thereby driving the first deburring grinding wheel 2312 to rotate, so as to grind the first annular surface of the brake disc 1.

[0058] In one embodiment, such as Figure 5As shown, the first grinding wheel drive structure 2313 includes a first grinding wheel drive motor 23131 and a transmission belt 23132. The first grinding wheel drive motor 23131 is vertically mounted on the base 2311, and the transmission belt 23132 is connected to the output shaft of the first grinding wheel drive motor 23131. Specifically, the output shaft of the first grinding wheel drive motor 23131 and the transmission belt 23132 are located on the lower side of the mounting plane to reduce installation space. The power generated by the first grinding wheel drive motor 23131 is transmitted to the transmission belt 23132 through the output shaft, and then transmitted by the transmission belt 23132 to the drive shaft of the first deburring spindle 2310, thereby allowing the first deburring grinding wheel 2312 to rotate around the drive shaft. In one example, the first grinding wheel drive motor 23131 is configured as a rotary motor.

[0059] In one embodiment, the first deburring wheel 2312 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 2312 is circular and has a through hole in the middle. The drive shaft of the first deburring spindle 2310 is connected to the first deburring wheel 2312 through the through hole. In some examples, the first deburring wheel 2312 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 2312 has vents for heat dissipation.

[0060] In one embodiment, such as Figure 6 As shown, the first deburring grinding wheel 2312 has multiple spaced arc-shaped cooling grooves 23121 through which coolant can pass. In one example, the coolant can be provided by a cooling device to cool the first deburring grinding wheel 2312, 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 23121 on the first deburring grinding wheel 2312 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.

[0061] In one embodiment, such as Figure 5As shown, a waterproof structure 2314 is provided on the periphery of the first deburring wheel 2312, which is used to prevent the coolant from splashing. Specifically, the waterproof structure 2314 can concentrate the coolant on the periphery of the first deburring wheel 2312, avoiding disorderly splashing of grinding fluid caused by the centrifugal force generated by the rotation of the first deburring wheel 2312.

[0062] In one implementation, the waterproof structure 2314 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 2312. 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 2312 deburrs the first annular surface, the waterproof cover lifting unit can lift the waterproof cover to surround the first deburring wheel 2312. 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.

[0063] In one embodiment, the diameter of the first deburring wheel 2312 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 held by the transfer robot 22 and placed on the first deburring wheel 2312 for grinding. Therefore, in this embodiment, the smaller diameter of the first deburring wheel 2312 compared to the brake disc 1 avoids mechanical collisions during the placement of the brake disc 1 by the transfer robot 22.

[0064] However, in embodiments where the diameter of the first deburring wheel 2312 is smaller than the diameter of the brake disc 1, the first deburring wheel 2312 can only grind the middle portion of the first annular surface, and cannot grind the entire annular surface. Therefore, in one embodiment, as... Figure 5 As shown, the first dressing mechanism 23 described in this application further includes a pressing and swaying device 232, which is disposed above the first deburring device 231 and is used to press and drive the brake disc 1 to sway. The pressing and swaying device 232 can expand the grinding range of the first deburring wheel 2312 on the first annular surface, thereby taking into account the grinding of the entire annular surface.

[0065] 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 232 includes a swing unit 2321, which can drive the brake disc 1 to swing. Figure 7In the illustrated embodiment, the rocking unit 2321 includes a rocking seat 23211, a mounting structure 23212, and a rocking drive structure 23213.

[0066] In one embodiment, the rocker seat 23211 is disposed on the base 2311. Specifically, as shown... Figure 5 As shown, the mounting plane of the base 2311 has a mounting hole 23111, and the rocker seat 23211 is generally cylindrical and is mounted on the base 2311 through the mounting hole 23111, for example, by screwing. In this embodiment, the rocker seat 23211 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 23211.

[0067] In one embodiment, such as Figure 7 As shown, the mounting structure 23212 is disposed on the rocker seat 23211. In one example, the second side of the mounting structure 23212 is connected to the rocker shaft of the rocker seat 23211, so that the first side of the mounting structure 23212 can rock around the rocker shaft, thereby causing the brake disc 1 to rock relative to the first deburring wheel 2312. In some examples, the mounting structure 23212 is configured as a rocker arm connected to the rocker shaft.

[0068] In one embodiment, such as Figure 7 As shown, a rocker arm 23214 for driving the brake disc 1 to rock is provided on one side of the mounting structure 23212. Specifically, the rocker arm 23214 can fix the brake disc 1 and, driven by the mounting structure 23212, cause the brake disc 1 to rock around the rocker axis relative to the first deburring wheel 2312, so as to achieve uniform and comprehensive grinding of the brake disc 1.

[0069] 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 23214 has a pressing surface 23215 on its lower side. The pressing surface 23215 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 2312 for oscillating grinding. In one example, the oscillating member 23214 is configured as an inverted disc-shaped structure, and the pressing surface 23215 is a circular plane with a diameter smaller than that of the brake disc 1.

[0070] In one embodiment, such as Figures 8 to 10As shown, a plurality of elastic limiting portions 23216 are provided on the pressing surface 23215, and the plurality of elastic limiting portions 23216 can fix the brake disc 1. Figure 10 As shown, the elastic limiting part 23216 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 23216 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 23216 can be inserted into the hole 121 to fix the brake disc 1. Furthermore, the elastic limiting part 23216 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 23216 ensures that the rocker member 23214 fixes the brake disc 1, while avoiding hard contact with the brake disc 1 when fixing it.

[0071] In one embodiment, such as Figure 9 As shown, 12 elastic limiting portions 23216 are arranged at intervals along the circumferential direction. Specifically, all 12 elastic limiting portions 23216 can extend into the inner edge of the brake disc. In some examples, not all elastic limiting portions 23216 can be inserted into the hole 121. In this example, the elastic limiting portions 23216 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 23216 inserted into the hole 121 is sufficient to stably fix the brake disc 1 with the rocker arm 23214. In this embodiment, the transfer robot 22 only needs to place the brake disc 1 on the first deburring wheel 2312 to complete the transfer operation, without having to adjust the orientation of the brake disc 1 so that the elastic limiting portions 23216 must correspond one-to-one with the holes 121, saving transfer time and thus improving processing efficiency.

[0072] In one embodiment, each time deburring is performed, at least four elastic limiting portions 23216 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 23216 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 23216 that cannot be inserted into the holes 121 corresponds to 8, 7, 6, 5, 4, 3, 2, 1, or 0, respectively.

[0073] In one embodiment, such as Figure 9As shown, auxiliary positioning portions 23217 are also provided on the pressing plane 23215, spaced apart from the elastic limiting portions 23216. Figure 9 In the example shown, the auxiliary positioning part 23217 is configured as a protrusion with a height lower than that of the elastic limiting part 23216, which helps to restrict the elastic limiting part 23216 to the inner edge of the brake disc.

[0074] As mentioned earlier, since the diameter of the first deburring wheel 2312 is smaller than the diameter of the brake disc 1, it is necessary to use the rocker arm 23214 to drive the brake disc 1 to swing so that the grinding range of the first deburring wheel 2312 completely covers the brake disc 1. Specifically, when the transfer robot 22 places the brake disc 1 on the first deburring wheel 2312, the brake disc 1 and the first deburring wheel 2312 have a relative initial position. During deburring, the rocker arm 23214 will drive the brake disc 1 to swing around the rocker axis between the first position and the second position under the mounting structure 23212.

[0075] 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 2312 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 2312 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 2312 coincides with the center O2 of the brake disc 1. Subsequently, the brake disc 1, driven by the rocker component 23214, swings counterclockwise around the axis O of the rocker shaft until... Figure 11 The 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 grinding wheel 2312 is fixed, while the center O2 of the brake disc 1 swings bidirectionally around the axis O.

[0076] It should be noted that, Figure 11 The first position shown and Figure 12The second position shown is merely illustrative, indicating the relative position of the brake disc 1 and the first deburring wheel 2312 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 2312 just covers the first annular surface of the brake disc 1. In practical applications, the swinging component 23214 can drive the brake disc 1 to swing at a larger angle to ensure comprehensive grinding.

[0077] In one embodiment, the swing member 23214 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 2312 and the diameter of the brake disc 1.

[0078] In one embodiment, such as Figure 7 As shown, the swing drive structure 23213 is disposed on one side of the swing base 23211 and is used to drive the mounting structure 23212 to swing around the swing axis to drive the swing component 23214 to swing.

[0079] In one embodiment, such as Figure 7 As shown, the swing drive structure 23213 includes a swing drive motor 23218, a first swing gear 23219, and a second swing gear 23220. The swing drive motor 23218 is disposed on the swing base 23211, the first swing gear 23219 is connected to the swing drive motor 23218, and the second swing gear 23220 is disposed on the mounting structure 23212 and meshes with the first swing gear 23219. The swing drive motor 23218 drives the first swing gear 23219 to rotate, thereby causing the mounting structure 23212 to swing around the swing axis.

[0080] In one embodiment, such as Figure 7 As shown, the pressing and swaying device 232 also includes a pressing unit 2322, which can press the brake disc 1 firmly onto the first deburring wheel 2312. Figure 7 In the example shown, the pressing unit 2322 includes a pressing drive structure 23221, which is disposed on the mounting structure 23212 and is used to drive the mounting structure 23212 to perform lifting and lowering movements, so as to cause the pressing surface 23215 of the rocker member 23214 to press or release the brake disc 1.

[0081] In one example, the clamping drive structure 23221 can be configured to include a clamping telescopic rod disposed vertically within the rocker seat 23211, and a clamping lifting cylinder disposed on the mounting structure 23212 for driving the clamping telescopic rod to extend and retract, thereby causing the mounting structure 23212 to move up and down. Specifically, the clamping lifting cylinder drives the clamping telescopic rod to extend, which can cause the mounting structure 23212 to rise, thereby causing the rocker component 23214 to rise to a height that does not interfere with the transfer robot 22's transfer operation. The clamping lifting cylinder drives the clamping telescopic rod to retract, which can cause the mounting structure 23212 to descend, thereby causing the rocker component 23214 to descend, so as to press the brake disc 1 onto the first deburring grinding wheel 2312, and ensure that the brake disc 1 is pressed onto the first deburring grinding wheel 2312 throughout the entire rocking motion, thereby ensuring the grinding effect of the deburring process.

[0082] In one embodiment, such as Figure 7 As shown, the mounting structure 23212 is further provided with a rotary drive structure 2323 adjacent to the clamping drive structure 23221. The rotary drive structure 2323 is used to drive the rocker member 23214 to rotate, thereby causing the brake disc 1 to rotate in the opposite direction relative to the first deburring wheel 2312. For example, if the first deburring wheel 2312 rotates clockwise, the rotary drive structure 2323 will drive the brake disc 1 to rotate counterclockwise; if the first deburring wheel 2312 rotates counterclockwise, the rotary drive structure 2323 will drive the brake disc 1 to rotate clockwise. In this embodiment, the first deburring wheel 2312 and the brake disc 1 rotate in opposite directions, further improving the efficiency of deburring. In one example, the clamping drive structure 23221 is configured to include a rotary motor.

[0083] In one embodiment, such as Figure 9 and Figure 10 As shown, the anti-swing device 232 also includes a nozzle 2324 disposed at the center of the swing member 23214 for discharging coolant to the brake disc 1. Specifically, the cooling device described in the foregoing embodiment can be disposed in the swing member 23214 and communicate with the nozzle 2324, so that coolant can be sprayed from the nozzle 2324 onto the brake disc 1, and then flow to the arc-shaped cooling groove 23121 on the first deburring wheel 2312, where it performs a cooling effect and is then collected by the waterproof structure 2314. In one example, the nozzle 2324 can spray the coolant in a fan shape to enhance the cooling effect.

[0084] 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 23 of this application is described in detail.

[0085] First, the transfer robot 22 transfers the brake disc 1 onto the first deburring wheel 2312. At this time, the brake disc 1 and the first deburring wheel 2312 are located at... Figure 11 The initial position is shown. Then, the pressing drive structure 23221 of the pressing rocker device 232 drives the mounting structure 23212 to descend, so that the elastic limiting part 23216 and the auxiliary positioning part 23217 on the pressing plane 23215 of the rocker member 23214 are positioned in the inner edge of the brake disc 1, while at least four elastic limiting parts 23216 are inserted into the holes 121 of the brake disc 1 to present a position. Figure 10 The state shown. At this time, the brake disc 1 is pressed between the first deburring wheel 2312 and the rocker element 23214 and presents... Figure 4 The state is shown. Then, the first deburring wheel 2312 rotates at high speed under the drive of the first wheel drive structure 2313, and the brake disc 1 rotates in the opposite direction to the first deburring wheel 2312 under the drive of the rotation drive structure 2323. At the same time, the brake disc 1 rotates in the opposite direction to the first deburring wheel 2312 under the drive of the swing drive structure 23213. Figure 12 The first position shown and Figure 13 The device swings between the second positions shown until the deburring of the first annular surface is completed. After the deburring is completed, the transfer robot 22 transfers the brake disc 1 to the second dressing mechanism 24 for deburring of the second annular surface and inner edge grinding.

[0086] In one embodiment, the transfer robot 22 may be configured to include a base, an articulated arm, and an end effector. The base is disposed on a base 21 and supports the articulated arm. The articulated arm provides the end effector with degrees of freedom of movement in space, enabling the end effector to transfer the brake disc. In one example, the transfer robot 22 is configured as a six-axis robot. In this example, the articulated arm is configured to include six axis assemblies, which may be individually or in combination disposed on the base, the articulated arm, and the end effector. Each axis assembly may provide rotational rotation about its axis or hinged rotation perpendicular to its axis.

[0087] In one embodiment, the end effector includes a first clamping plate, a second clamping plate, a clamping seat, and a clamping plate driving mechanism. The first clamping plate and the second clamping plate respectively form receiving spaces with the clamping seat for clamping the brake disc 1. Further, the first clamping plate and the second clamping plate are disposed at opposite ends of the clamping seat, and the clamping plate driving mechanism is used to drive at least one of the first clamping plate and the second clamping plate to move to adjust the clamping distance between the two clamping plates. In some examples, the clamping plate driving mechanism may include a lead screw and a driving source. The lead screw is disposed along the length direction of the clamping seat and associated with at least one of the first clamping plate and the second clamping plate. The driving source is used to drive the lead screw to rotate so that the associated at least one clamping plate moves along the length direction of the clamping seat. In some examples, the clamping plate driving mechanism may include a bidirectional lead screw and a driving source. The bidirectional lead screw is disposed along the length direction of the clamping seat and associated with the first clamping plate and the second clamping plate at both ends. The driving source is used to drive the bidirectional lead screw to rotate so that the first clamping plate and the second clamping plate move towards each other or away from each other along the length direction of the clamping seat. The clamping plate driving mechanism is not limited to this; it may also employ a telescopic rod and a driving cylinder or a driving hydraulic cylinder, etc.

[0088] In one embodiment, such as Figure 3 As shown, the second trimming mechanism 24 is disposed in the pre-processing area 212 and located near the transfer robot 22 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 24 includes a second deburring device 241 and an inner edge grinding device 242. The second deburring device 241 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 242 is used to perform grinding operations on the inner edge of the brake disc 1.

[0089] In one embodiment, such as Figure 14 As shown, the second dressing mechanism 24 also includes a support frame 243, which is laterally arranged on the base 21 for mounting the second deburring device 241 and the inner edge grinding device 242. In some examples, the support frame 243 may be configured as a gantry frame to support the components or structures in the second deburring device 241 and the inner edge grinding device 242, 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.

[0090] 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 14and 15 As shown, the second deburring device 241 includes a first grinding frame 2411 and a deburring assembly 2412. The first grinding frame 2411 is movably mounted on the support frame 243. The deburring assembly 2412 is used to deburr the second annular surface of the brake disc 1. In some examples, the first grinding frame 2411 serves as a carrier for the deburring assembly 2412 mounted on the support frame 243, and its specific form can be a beam, column, plate frame, bracket, etc.

[0091] In one embodiment, such as Figure 15 As shown, the deburring assembly 2412 includes a second deburring spindle 24121 and a second deburring grinding wheel 24122. The second deburring spindle 24121 is fixedly mounted vertically on the first grinding frame 2411, and the second deburring grinding wheel 24122 is disposed at the end of the second deburring spindle 24121 for deburring the second annular surface of the brake disc 1.

[0092] In one embodiment, the second deburring spindle 24121 includes a drive shaft connected to a second deburring wheel 24122. 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 24122 to rotate at high speed to deburr the second annular surface of the brake disc 1.

[0093] In one embodiment, the second deburring wheel 24122 is configured as a coarse grinding wheel. In one example, as... Figure 14 As shown, the diameter of the second deburring wheel 24122 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 24122 can completely cover the second annular surface of the rotating brake disc, thereby ensuring the comprehensiveness of the grinding.

[0094] In one embodiment, the second deburring device 241 further includes a first lateral moving structure and a first lifting structure. The first lateral moving structure is disposed on the support frame 243 and is used to drive the first grinding frame 2411 to move laterally on the support frame 243. The first lifting structure is disposed on the first grinding frame 2411 and is used to drive the deburring assembly 2412 to move up and down. In this embodiment, the deburring assembly 2412 moves relative to the support frame 243 along the first grinding frame 2411. Figure 15 The arrows in the diagram indicate horizontal and vertical movement.

[0095] 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 243. The first lateral movement drive motor drives the first lateral movement lead screw to rotate, thereby causing the deburring assembly 2412 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 2412 is moved on the first lateral movement guide rail.

[0096] In one embodiment, the first lifting structure includes a first lifting moving guide rail disposed vertically on the first grinding frame 2411, a first lifting moving slider disposed on the second outer edge grinding spindle 2213 and connected to the first lifting moving guide rail, and a first lifting moving cylinder disposed on the first grinding frame 2411 for driving the first lifting moving slider to slide on the first lifting moving guide rail to drive the deburring assembly 2412 to perform lifting and lowering movements.

[0097] In practical applications, to ensure stable lifting and lowering of the deburring assembly 2412 on the first grinding frame 2411, 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 2412, 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 2412 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 2412 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.

[0098] 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 242 includes a second grinding frame 2421 and an inner edge grinding assembly 2422. The second grinding frame 2421 is movably mounted on a support frame 243, and the inner edge grinding assembly 2422 is used to perform grinding operations on the inner edge of the brake disc. In some examples, the second grinding frame 2421 serves as a carrier for the inner edge grinding assembly 2422 mounted on the support frame 243, and its specific form can be a beam, column, plate, bracket, etc.

[0099] In one embodiment, such as Figure 16 As shown, the inner edge grinding assembly 2422 includes an inner edge grinding spindle 24221 and an inner edge grinding wheel 24222. The inner edge grinding spindle 24221 is vertically fixed on the second grinding frame 2421, and the inner edge grinding wheel 24222 is disposed at the end of the inner edge grinding spindle 24221 for performing inner edge grinding operations. The structure of the inner edge grinding spindle 24221 and the inner edge grinding wheel 24222 can be referred to the description of the second deburring spindle 24121 and the second deburring wheel 24122 in the previous embodiments, and will not be repeated here.

[0100] In one embodiment, the inner edge grinding device 242 further includes a second lateral moving structure and a second lifting structure. The second lateral moving structure is disposed on the support frame 243 and is used to drive the second grinding frame 2421 to move laterally on the support frame 243. The second lateral moving structure is disposed on the second grinding frame 2421 and is used to drive the inner edge grinding assembly 2422 to move vertically. 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.

[0101] In one embodiment, the second deburring device 241 and the inner edge grinding device 242 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 2412 and the inner edge grinding assembly 2422 to move laterally relative to each other, so that the second deburring wheel 24122 and the inner edge grinding wheel 24222 respectively reach above the brake disc 1. Subsequently, the first lifting structure and the second lifting structure simultaneously drive the deburring assembly 2412 and the inner edge grinding assembly 2422 to descend, so that the second deburring wheel 24122 and the inner edge grinding wheel 24222 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 24222 is smaller than the diameter of the second deburring wheel 24122, ensuring that the inner edge grinding wheel 24222 does not interfere with the second deburring wheel 24122 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 24222 is configured as a rough grinding wheel. In some examples, the working time of the second deburring device 241 in deburring the second annular surface is equal to the time of the inner edge grinding device 242 in performing inner edge grinding.

[0102] In one embodiment, such as Figure 14 As shown, the second dressing mechanism 24 also includes a grinding wheel dressing device 244 for dressing the second deburring grinding wheel 24122 and the inner edge grinding wheel 24222. Figure 14 In the example shown, the grinding wheel dressing device 244 is configured in two parts to dress the second deburring grinding wheel 24122 and the inner edge grinding wheel 24222 respectively, so as to avoid wear or dulling of the grinding wheel after long-term inner edge grinding operation, thereby ensuring grinding accuracy.

[0103] In one embodiment, the grinding wheel dressing device 244 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] In one embodiment, such as Figure 14 As shown, the second trimming mechanism 24 also includes a brake disc support device 245 disposed at the distal end of the support frame 243 for horizontally placing the brake disc 1. (See also...) Figure 17 The image shown is a structural schematic diagram of a brake disc support device in one embodiment of this application. Figure 17 As shown, the brake disc support device 245 includes a support base 2451 and a clamping unit 2452. The support base 2451 is disposed on the base 21, and the clamping unit 2452 is disposed on the support base 2451 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 23, the outer edge of the brake disc 1 can be clamped by the transfer robot 22 and transferred to the clamping unit 2452. The clamping unit 2452 clamps the outer edge for inner edge grinding and deburring of the second annular surface.

[0108] It should be noted here that, Figure 14 The brake disc support device 245 shown is surrounded by a cover. Figure 17The omission of the brake disc support device 245 structure of the cover should not be construed as a limitation on the embodiment.

[0109] In one embodiment, the support 2451 supports the clamping unit 2452 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 2451 is configured as a seat on the base 21, which may contain a rotating shaft so that the clamping unit 2452 can hold the brake disc and rotate it around the rotating shaft for grinding the brake disc.

[0110] In one embodiment, such as Figure 17 As shown, the clamping unit 2452 includes a support ring 24521 and a claw 24522. The support ring 24521 is used to support the brake disc, and the claw 24522 is disposed around the support ring 24521 to clamp the brake disc.

[0111] In one embodiment, the outer diameter of the support ring 24521 is smaller than the diameter of the brake disc, thereby avoiding mechanical collisions when the transfer robot 22 places the brake disc 1.

[0112] In one embodiment, the chuck 24522 is 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 chucks is 120°, thereby providing a uniform clamping force to the brake disc. In some examples, the side of the chuck 24522 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.

[0113] In one embodiment, the clamping unit 2452 further includes an opening and closing drive unit for driving the jaws 24522 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 24522 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.

[0114] 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 24 of this application is described in detail.

[0115] First, the transfer robot 22 transfers the brake disc, which has undergone deburring of the first annular surface, to the brake disc support device 245, where the outer edge of the brake disc is held by the jaws 24522. Then, the second deburring device 241 and the inner edge grinding device 242 operate simultaneously. The first and second lateral moving structures simultaneously drive the deburring assembly 2412 and the inner edge grinding assembly 2422 to move laterally relative to each other, so that the second deburring wheel 24122 and the inner edge grinding wheel 24222 reach above the brake disc 1. Afterward, the first and second lifting structures simultaneously drive the deburring assembly 24122 and the inner edge grinding assembly 24222 to descend, so that the second deburring wheel 24122 and the inner edge grinding wheel 24222 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.

[0116] In one embodiment, such as Figure 3 As shown, the outer edge grinding mechanism 25 is located in the pretreatment area 212 and at the distal end of the transfer robot 22 to receive the brake disc after completing the second deburring and inner edge grinding operations. See also... Figure 18 The diagram shows a schematic representation of the outer edge grinding mechanism in one embodiment of this application. Figure 18 As shown, the outer edge grinding mechanism 25 includes an outer edge grinding device 251 for grinding the outer edge of the vertically placed brake disc.

[0117] In one embodiment, such as Figure 18 As shown, the outer edge grinding mechanism 25 also includes a forward / backward drive device 252 disposed on the base 21, which is used to drive the outer edge grinding device 251 to move longitudinally. In some examples, the forward / backward drive device 252 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 251 to move on the longitudinal guide rail.

[0118] In one embodiment, such as Figure 18 As shown, the outer edge grinding mechanism 22 further includes a lateral drive device 253 disposed above the forward / reverse drive device 252 for driving the outer edge grinding device 251 to move laterally to approach the brake disc. In some examples, the lateral drive device 253 may include a lateral guide rail, a lateral movement screw, and a lateral movement drive motor disposed on the forward / reverse drive device 252, wherein the lateral movement drive motor drives the lateral movement screw to rotate, thereby driving the outer edge grinding device 251 to move on the lateral guide rail.

[0119] In one embodiment, such as Figure 18As shown, the outer edge grinding device 251 includes an outer edge grinding machine base 2511, a first outer edge grinding spindle 2512, and a second outer edge grinding spindle 2513. The first outer edge grinding spindle 2512 is fixedly mounted on the outer edge grinding machine base 2511, and the second outer edge grinding spindle 2513 is vertically and flexibly mounted on the upper side of the first outer edge grinding spindle 2512. Specifically, the outer edge grinding machine base 2511 is located above the transverse drive device 253, the first outer edge grinding spindle 2512 is mounted on the outer edge grinding machine base 2511, and the second outer edge grinding spindle 2513 is mounted on the upper side of the first outer edge grinding spindle 2512. That is, the first outer edge grinding spindle 2512 and the second outer edge grinding spindle 2513, driven by the outer edge grinding machine base 2511, approach the outer edge 11 of the brake disc 1 through the transverse drive device 253, and perform feed grinding on the outer edge 11 through the forward and backward drive device 252.

[0120] In one embodiment, such as Figure 18 As shown, the outer edge grinding device 251 also includes a lifting drive structure 2514, which is disposed on the outer edge grinding machine base 2511 and is used to drive the second outer edge grinding spindle 2513 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 2513, the contact depth between the second outer edge grinding spindle 2513 and the brake disc 1 can be adjusted. For example, if the lifting drive structure 2514 controls the second outer edge grinding spindle 2513 to move downwards, the second outer edge grinding spindle 2513 can make deeper contact with the outer edge 11 of the brake disc 1, thereby increasing the grinding amount; if the lifting drive structure 2514 controls the second outer edge grinding spindle 2513 to move upwards, the contact depth between the second outer edge grinding spindle 2513 and the outer edge 11 of the brake disc 1 can become shallower, thereby reducing the grinding amount.

[0121] In one embodiment, such as Figure 18 As shown, the proximal end of the first outer edge grinding spindle 2512 has a first grinding wheel 25121, and the proximal end of the second outer edge grinding spindle 2513 has a second grinding wheel 25131. The first outer edge grinding spindle 2512 and the second outer edge grinding spindle 2513 may have the same configuration.

[0122] In one embodiment, the first grinding wheel 25121 and the second grinding wheel 25131 are staggered. This staggered arrangement means that the first grinding wheel 25121 and the second grinding wheel 25131 are not completely aligned in space, causing the contact positions of their rims on the outer edge 11 of the brake disc 1 to be offset and spaced apart. This avoids repeated grinding at the same position on the outer edge 11 by the first grinding wheel 25121 and the second grinding wheel 25131. The collaborative processing of the two grinding wheels expands the coverage of a single grinding operation, thereby improving grinding efficiency.

[0123] Please see Figures 19 to 21 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 19 to 21 All are presented as top views. It should be noted here that... Figures 19 to 21 The relative positions of the first grinding wheel 25121 and the second grinding wheel 25131 are only schematically illustrated and should not be construed as limiting this application. Figures 19 to 21 In the example shown, the first grinding wheel 25121 and the second grinding wheel 25131 are connected to each other in the longitudinal direction. However, in some other examples, the first grinding wheel 25121 and the second grinding wheel 25131 may partially overlap or have a certain gap in the longitudinal direction, depending on the actual grinding requirements.

[0124] In one embodiment, such as Figures 19 to 21 As shown, the first grinding wheel 25121 and the second grinding wheel 25131 are misaligned, so that the first grinding wheel 25121 first grinds the outer edge 11 to form a first step structure A1 by moving laterally, and the second grinding wheel 25131 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 25121 and the second grinding wheel 25131 grind the first step structure A1 and the second step structure A2 in sequence by moving longitudinally to complete the outer edge grinding operation.

[0125] Specifically, such as Figure 19 As shown, the transverse drive device 253 drives the first grinding wheel 25121 and the second grinding wheel 25131 along... Figure 19 The arrow in the image approaches the outer edge 11, causing the first grinding wheel 25121 to perform the first grinding on the outer edge 11 to form the first step structure A1, thus presenting... Figure 20The state shown. Next, the second grinding wheel 25131, driven by the lifting drive structure 2514, descends to a preset position determined according to the grinding amount. Simultaneously, the first grinding wheel 25121 and the second grinding wheel 25131, driven by the forward and backward drive device 252, move along... Figure 20 The second grinding wheel 25131 moves in the direction of the arrow to contact the outer edge 11 for a second grinding process, thereby forming... Figure 21 The second step structure A2 is shown. Then, the first grinding wheel 25121 and the second grinding wheel 25131 move along the path driven by the forward and backward drive device 252. Figure 21 Move in the direction of the arrow until the grinding operation is completed on the outer edge 11.

[0126] The following combination Figures 18 to 21 The process of performing peripheral grinding operations using the peripheral grinding mechanism 25 of this application is described in detail.

[0127] First, the first grinding wheel 25121 and the second grinding wheel 25131 of the outer edge grinding device 251 are driven by the transverse drive device 253 along the edge... Figure 19 The arrow in the image approaches the outer edge 11, causing the first grinding wheel 25121 to perform the first grinding on the outer edge 11 to form the first step structure A1, thus presenting... Figure 20 The state shown. Next, within a preset time interval, the second grinding wheel 25131 descends to a preset position determined according to the grinding amount under the drive of the lifting drive structure 2514. Simultaneously, the first grinding wheel 25121 and the second grinding wheel 25131 move along the path driven by the forward and backward drive device 252. Figure 20 The second grinding wheel 25131 moves in the direction of the arrow to contact the outer edge 11 for a second grinding process, thereby forming... Figure 21 The second step structure A2 is shown. Then, the first grinding wheel 25121 and the second grinding wheel 25131 move along the path driven by the forward and backward drive device 252. Figure 21 Move in the direction of the arrow until the outer edge is ground.

[0128] In one embodiment, such as Figure 3 As shown, the annular grinding mechanism 26 is disposed in the annular processing area 211, and includes three annular grinding devices and a rotating mechanism 264. The three annular grinding devices are used to grind the first and second annular surfaces of the vertically placed brake disc, which have already undergone outer edge grinding. The rotating mechanism 264 is disposed between the three annular grinding devices and is used to transfer the brake disc between the three annular grinding devices and the outer edge grinding device 251. It should be noted here that, for ease of description and explanation, as... Figure 3As shown, in subsequent embodiments, the three annular grinding devices are referred to sequentially in a counterclockwise direction as the first annular grinding device 261, the second annular grinding device 262, and the third annular grinding device 263.

[0129] In one embodiment, the grinding time of the first toroidal grinding device 261, or the second toroidal grinding device 262, or the third toroidal grinding device 263 is one-third of the grinding time of the outer edge grinding device 221. For example, if the outer edge grinding device 251 performs outer edge grinding for 60 seconds, then the toroidal grinding time of the first toroidal grinding device 261, the second toroidal grinding device 262, and the third toroidal grinding device 263 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 264 to drive the brake disc to rotate between the outer edge grinding device 221 and the first annular grinding device 261, the second annular grinding device 262, and the third annular grinding device 263, the brake disc can complete the annular grinding operation in parallel while completing the outer edge grinding operation, which helps to improve the efficiency of the overall processing cycle and realize the continuous automated grinding of the brake disc.

[0130] In one embodiment, the grinding amount of the first annular grinding device 261, or the second annular grinding device 262, or the third annular grinding device 263 on the brake disc is 1 / 3 of the total annular grinding amount. For example, when the total annular grinding amount on 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.

[0131] In one embodiment, a first annular grinding device 261, a second annular grinding device 262, and a third annular grinding device 263 are arranged around the annular machining area 211. Figure 3 In the example shown, the first toroidal grinding device 261, the second toroidal grinding device 262, and the third toroidal grinding device 263 are arranged in a fan shape around the rotating mechanism 264. The included angles between the second toroidal grinding device 262 and the first toroidal grinding device 261, and between the second toroidal grinding device 262 and the third toroidal grinding device 263, are both 90°. Further, the included angle between the outer edge grinding device 251 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 264, realizing the automated rotation and alignment of the brake disc.

[0132] The first annular grinding device 261, the second annular grinding device 262, and the third annular grinding device 263 have the same configuration. The structure of each annular grinding device will be described below using the first annular grinding device 261 as an example. Please refer to... Figure 22 The image shown is a schematic diagram of the structure of the first annular grinding apparatus in one embodiment of this application. Figure 22 As shown, the toroidal grinding mechanism 26 further includes a first driving device 265 and a second driving device 266. The first driving device 265 is disposed on the base 21 and is used to drive the first toroidal grinding device 261 to approach the rotating mechanism 264. The second driving device 266 is disposed above the first driving device 265 and is used to drive the first toroidal grinding device 261 to approach the toroidal surface 13 of the brake disc for grinding. The specific structures of the first driving device 265 and the second driving device 266 can be found in the description of the forward and backward driving device 252 and the lateral driving device 253 in the foregoing embodiments, and will not be repeated here.

[0133] In one embodiment, such as Figure 22 As shown, the first annular grinding device 261 includes a first annular grinding spindle 2611 and a second annular grinding spindle 2612. The first annular grinding spindle 2611 and the second annular grinding spindle 2612 are arranged side by side above the second driving device 266 and can move towards each other along the second driving device 266 to grind the annular surfaces 13 on opposite sides of the brake disc respectively. Figure 22 In the example shown, both the first toroidal grinding spindle 2611 and the second toroidal grinding spindle 2612 have a grinding wheel. For ease of description, the grinding wheel of the first toroidal grinding spindle 2611 is referred to as the first toroidal grinding wheel 26111, and the grinding wheel of the second toroidal grinding spindle 2612 is referred to as the second toroidal grinding wheel 26121. The first toroidal grinding wheel 26111 and the second toroidal grinding wheel 26121 will not be described in detail thereafter.

[0134] Specifically, in this embodiment, the brake disc is rotated by the rotating mechanism 264 to a position between the first annular grinding wheel 26111 and the second annular grinding wheel 26121. The two annular grinding wheels move towards each other a certain distance under the drive of the second driving device 266 (this distance is determined according to the grinding amount). Then, the two annular grinding wheels approach the rotating mechanism 264 under the drive of the first driving device 265, thereby performing annular grinding on the brake disc 1.

[0135] Please see Figure 23 The image shown is a partially enlarged schematic diagram of the first annular grinding device in one embodiment of this application. Figure 23As shown, a liftable thickness detection device 267 for detecting the thickness of the brake disc 1 to determine the feed rate is provided between the first annular grinding spindle 2611 and the second annular grinding spindle 2612. Figure 23 In the illustrated embodiment, the thickness detection device 267 is configured to include a lifting mechanism 2671 and a detection head assembly 2672. The detection head assembly 2672 is used to detect the thickness of the brake disc 1. The lifting mechanism 2671 is used to drive the detection head assembly 2672 to move up and down vertically, so that the detection head assembly 2672 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 264 and the grinding operation when detection is not needed. In some examples, the lifting mechanism 2671 may be configured to achieve the lifting movement by means of electric screw lifting, cylinder drive, or servo motor drive.

[0136] Please see Figure 24 The diagram shows a schematic representation of the rotating mechanism in one embodiment of this application. Figure 24 As shown, the rotating mechanism 264 includes a rotating seat 2641, a rotating support 2642, and a shaft 2643.

[0137] In one embodiment, the rotating base 2641 is disposed on the base 21 and is used to support the vertically placed brake disc 1, having a rotating platform 26411 on it. In this embodiment, the rotating base 2641 is fixedly disposed on the base 21, and may be integrally formed with the base 21, for example. In some examples, to achieve stable support for components such as the brake disc 1 and the rotating bracket 2642, the rotating base 2641 may be configured to be made of materials such as cast iron or stainless steel. Figure 24 In the example shown, the swivel base 2641 is configured as a cylinder to minimize its footprint.

[0138] In one embodiment, the rotating table 26411 can rotate relative to the rotating base 2641 to drive the rotating support 2642 thereon to rotate, thereby causing the brake disc 1 to rotate between the outer edge grinding device 251, the first annular grinding device 261, the second annular grinding device 262, and the third annular grinding device 263. In some examples, the rotating table 26411 is equipped with an angle encoder to ensure that its rotation angle is 90° each time. In some examples, the rotating table 26411 is equipped 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 251 or any of the annular grinding devices.

[0139] Please see Figure 25 This application is displayed as such. Figure 24 A schematic diagram of the rotating bracket in the illustrated embodiment. Figure 24 and Figure 25 As shown, the rotating support 2642 includes four support arms 26421 disposed on the rotating table 26411, 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 251, the first annular grinding device 261, the second annular grinding device 262, and the third annular grinding device 263. In this embodiment, the four support arms 26421 are centrally symmetrically arranged on the rotating table 26411 along the axis of the rotating seat 2641. Specifically, under the support of a support arm 26421 on the rotating bracket 2642, the brake disc 1 completes the outer edge grinding operation using the outer edge grinding device 221. Then, the rotating bracket 2642 rotates 90° counterclockwise under the drive of the rotating table 26411, rotating the brake disc that has completed the outer edge grinding operation to the first annular grinding device 261 to start the annular grinding operation. Subsequently, one-third of the annular grinding operation is completed at the first annular grinding device 261, the second annular grinding device 262, and the third annular grinding device 263.

[0140] In one embodiment, such as Figure 24 and Figure 25 As shown, a shaft 2643 is vertically disposed at one end of each of the support arms 26421, and has a claw portion 26431 that can be opened and closed to fix the inner edge of the brake disc 1. In one example, the claw portion 26431 is configured as a three-claw structure, which is equidistantly arranged around the circumference of the shaft 2643. 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 2643 may be configured as a hollow structure, with an opening and closing drive structure inside for driving the claw portion 26431 to open and close, so as to drive the claw portion 26431 to retract towards the axis to fix the inner edge of the brake disc.

[0141] In one embodiment, such as Figure 25 As shown, the rotating mechanism 264 also includes a rotating drive device 2644, which is used to drive the brake disc 1 to rotate around its center. Figure 25 In the illustrated embodiment, the rotary drive device 2644 is disposed on the back side of the support arm 26421 (the side opposite to the side where the shaft 2643 is disposed). For an example of one rotary drive device 2644, please refer to [link to example document]. Figure 26 ,in, Figure 26 This application is displayed. Figure 25 A schematic diagram of the rotary drive device in the embodiment. Figure 26As shown, the rotary drive device 2644 includes a rotary drive motor 26441 disposed at the other end of the support arm 26421, and a conveyor belt 26443 connecting the output shaft 26442 of the rotary drive motor 26441 and the shaft body 2643. The rotary drive motor 26441 transmits power to the shaft body 2643 through the conveyor belt 26443, thereby causing the shaft body 2643 to drive the brake disc to rotate.

[0142] The following combination Figures 22 to 26 The process of performing toroidal grinding operations using the toroidal grinding mechanism 26 of this application is described in detail.

[0143] The aforementioned transfer mechanism 24 can transfer the brake disc, after inner edge grinding and deburring, to the shaft 2643 of the rotating mechanism 264, so that the outer edge grinding device 251 can complete the outer edge grinding operation. Subsequently, the rotating support 2642 rotates 90° counterclockwise under the drive of the rotating table 26411, rotating the brake disc, after outer edge grinding, to the first annular grinding device 261. Then, the thickness detection device 267 descends to both sides of the brake disc 1 to detect the thickness of the brake disc to determine the feed rate. After detection, the thickness detection device 267 rises to a position that does not interfere with the grinding operation.

[0144] The first toroidal grinding wheel 26111 and the second toroidal grinding wheel 26121 move towards each other under the drive of the second drive device 266, and then approach the rotating mechanism 264 under the drive of the first drive device 265, thereby performing one-third of the overall toroidal grinding operation on the brake disc 1. Afterwards, the rotating support 2642 rotates 90° counterclockwise under the drive of the rotating table 26411 to rotate the brake disc to the second toroidal grinding device 262. After completing two-thirds of the overall toroidal grinding operation, the rotating support 2642 rotates 90° counterclockwise again to rotate the brake disc to the third toroidal grinding device 263 to complete the remaining one-third of the toroidal grinding operation. Then, the transfer robot 22 can unload the brake disc after the inner edge grinding operation is completed.

[0145] In one embodiment, such as Figure 3 As shown, the multi-station brake disc grinding equipment 2 also includes a positioning mechanism 27, which is disposed on the base 21 and used to push the brake disc transferred to the claw 26431 by the transfer robot. In this embodiment, the positioning mechanism 27 can further ensure that the brake disc 1 is fixed in place on the rotating mechanism 264, thereby preventing the brake disc from detaching from the claw 26431 during the outer edge grinding operation or the toroidal grinding operation.

[0146] Please see Figure 27 The image shown is a schematic diagram of the positioning mechanism in one embodiment of this application. Figure 27As shown, the positioning mechanism 27 includes a push block 271, a positioning telescopic structure 272, and a positioning lifting structure 273. The push block 271 is used to push the brake disc, the positioning telescopic structure 272 is used to drive the push block 271 to move longitudinally, and the positioning lifting structure 273 is disposed on the base 21 to drive the push block 271 to rise and fall.

[0147] In one embodiment, such as Figure 27 As shown, the pusher block 271 is configured as a disc-shaped structure with a pusher plane. When pushing the brake disc, the center of the pusher plane coincides with the center of the brake disc 1, so that the brake disc is subjected to uniform force. In practical applications, the pusher block 271 pushes the center of the brake disc 1 under the action of the positioning telescopic structure 272 and the positioning lifting structure 273, so as to firmly fix the brake disc 1 on the claw portion 26431, so that the subsequent outer edge grinding operation and the ring surface grinding operation can be carried out smoothly.

[0148] In one embodiment, the positioning telescopic structure 272 includes a positioning telescopic rod and a positioning telescopic drive unit (not shown). The push block 271 is disposed at the end of the positioning telescopic rod, and the positioning telescopic drive unit is used to drive the positioning telescopic rod to perform telescopic movement to drive the push block 271 to move longitudinally. In some examples, the positioning telescopic drive unit is connected to the positioning telescopic rod, and when the positioning telescopic rod is extended, it drives the push block 271 to extend, thereby driving the push block 271 to move longitudinally to push the brake disc; when the positioning telescopic rod is retracted, it drives the push block 271 to retract away from the brake disc.

[0149] In one embodiment, the positioning and lifting structure 273 is configured to include a positioning and lifting screw and a positioning and lifting motor, wherein the positioning and lifting screw is arranged vertically and the positioning and lifting motor is connected to the positioning and lifting screw. Thus, the positioning and lifting motor drives the positioning and lifting screw to rotate, thereby realizing the lifting and lowering movement of the push block 271, allowing the push block 271 to rise to the center height of the brake disc 1 for pushing, and then lowering it back to the initial position after pushing the brake disc into place.

[0150] In one embodiment, such as Figure 2 and Figure 3As shown, the multi-station brake disc grinding equipment 2 also includes a loading conveyor mechanism 28 connected to the base 21 for loading the brake disc 1, and a unloading conveyor mechanism 29 for unloading. In this embodiment, the transfer robot 22 is used to transfer the brake disc 1 from the loading conveyor mechanism 28 to the first dressing mechanism 23, and from the toroidal grinding mechanism 26 to the unloading conveyor mechanism 29. Specifically, the transfer robot 22 transfers the brake disc 1 on the feeding conveyor 28 to the first dressing mechanism 23 for deburring the first annular surface. Then, the brake disc with the deburred first annular surface is transferred to the second dressing mechanism 24. After the brake disc has completed the deburring of the second annular surface and the inner edge grinding operation, it is transferred to the rotating mechanism 264, where the outer edge grinding mechanism 25 performs the outer edge grinding operation. The disc is then rotated by the rotating mechanism 264 to the third annular surface grinding device 263 to complete the annular surface grinding operation. After that, the transfer robot 22 transfers the brake disc with the completed annular surface grinding operation to the unloading conveyor 29 for unloading.

[0151] The loading conveyor mechanism 28 and the unloading conveyor mechanism 29 can have the same configuration. Taking the loading conveyor mechanism 28 as an example, please refer to [link / reference]. Figure 28 The image shown is a schematic diagram of the feeding and conveying mechanism in one embodiment of this application. Figure 28 As shown, the feeding and conveying mechanism 28 includes a conveying platform 281, a plurality of first bearing structures 282 and a plurality of second bearing structures 283.

[0152] In one embodiment, the conveyor table 281 is laterally connected to the base 21 and has an internal cavity 2811. In one example, the conveyor table 281 is configured as a hollow cuboid structure, the hollow portion forming the cavity 2811 to house the plurality of second support structures 283. In some examples, the conveyor table 281 may be configured as fixed to accommodate scenarios where the brake disc multi-station grinding equipment 2 is relatively fixed, or configured as sliding to facilitate operator movement.

[0153] In one embodiment, such as Figure 28 As shown, multiple first support structures 282 are fixedly straddling the conveyor table 281 to support multiple vertically placed brake discs 1. Each first support structure 282 has a clearance space in the middle, and there is a preset interval between each first support structure 282. Figure 28In the illustrated implementation, each first support structure 282 is configured to include two corresponding first support boxes respectively disposed on both sides of the support platform 281. 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 282 is configured to be 10.

[0154] In one embodiment, such as Figure 28 As shown, multiple second supporting structures 283 are movably disposed within the cavity. Please refer to... Figure 29 The diagram shows a second load-bearing structure disposed within a cavity in one embodiment of this application. It should be noted that the diagram is for illustrative purposes only, to clearly demonstrate the structure of the second load-bearing structure 283. Figure 29 The structure of the support platform 2811 and the first support structure 282 is omitted. For example... Figure 29 As shown, the second support structure 283 is configured to include a second support box disposed within the cavity 2811. 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 inside the first support box. Furthermore, the spacing between each of the second support structures 283 is equal to the preset interval between the first support structures 282, so that when the second support structure 283 rises from the clearance space, it can transfer all the brake discs loaded in the first support structure 282 into the second support box.

[0155] In one embodiment, the plurality of second support structures 283 may be fixed to a movable plate, such that the plurality of second support structures 283 may simultaneously actuate within the cavity 2811 to support the brake disc 1 in the first support structure 282. In some examples, the number of second support structures 283 is configured to be nine.

[0156] In one embodiment, the feeding and conveying mechanism 28 further includes a loading and unloading lifting drive structure for driving the plurality of second bearing structures 283 to perform lifting and lowering movements, and a loading and unloading lateral drive structure for driving the plurality of second bearing structures 283 to move laterally. That is, the plurality of second bearing structures 283 can perform lateral and lifting movements within the cavity 2811. 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 283 to perform lateral and lifting movements.

[0157] In one embodiment, the second support structure 283 is used to rise and support the first support structure 282 at the first end when it is empty, thereby causing the brake disc 1 to move laterally towards the first end by the predetermined interval. After filling the empty space of the first support structure 282 at the first end, it descends again and moves laterally to the second end of the cavity for the next filling. Specifically, please refer to... Figures 30 to 32 The figures shown are schematic diagrams illustrating the feeding and conveying process of the second load-bearing structure in one embodiment of this application.

[0158] like Figure 30 As shown, 10 first bearing structures 282 support 10 brake discs 1. The transfer robot 22 removes the brake discs 1 closest to the base 21 and transfers them to the first trimming mechanism 23. Figure 31 As shown, the first bearing structure 282 at the first end of the feeding conveyor mechanism 28 is in an empty state. At this time, the second bearing structure 283, driven by the loading and unloading lifting drive structure, pushes the remaining 9 brake discs out of the first bearing structure 282, and moves towards the first end under the drive of the loading and unloading lateral drive structure until it is aligned with the first bearing structure 282. Then it descends to load the 9 brake discs onto the first bearing structure 282, and presents a... Figure 32 The state shown is used to fill the gap in the first load-bearing structure 282 at the first end, while simultaneously leaving the first load-bearing structure 282 at the second end vacant. The transfer robot 22 can... Figure 32 In the indicated state, continue removing the brake disc from the first end, while simultaneously, the brake disc can be manually loaded onto the first load-bearing structure 282 at the second end. The second load-bearing structure 283 repeats the above actions to load the brake disc.

[0159] The following combination Figures 1 to 32 The process of deburring the first and second annular surfaces, grinding the inner edge, grinding the outer edge, and grinding the annular surface using the multi-station brake disc grinding equipment 2 provided in this application is described in detail.

[0160] First, the transfer robot 22 transfers the brake disc 1 from the feeding conveyor 28 to the first dressing mechanism 23 in the pretreatment area 212, and places it horizontally on the first deburring wheel 2312. Then, the pressing drive structure 23221 of the pressing swing device 232 drives the mounting structure 23212 to descend, so that the elastic limiting part 23216 is inserted into the hole 121 of the brake disc 1, and the brake disc 1 is pressed between the first deburring wheel 2312 and the swing member 23214 and presented as a single unit. Figure 4The state is shown. Then, the first deburring wheel 2312 rotates at high speed under the drive of the first wheel drive structure 2313, and the brake disc 1 rotates in the opposite direction to the first deburring wheel 2312 under the drive of the rotation drive structure 2323. At the same time, the brake disc 1 rotates in the opposite direction to the first deburring wheel 2312 under the drive of the swing drive structure 23213. 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.

[0161] After the deburring of the first annular surface is completed, the transfer robot 22 transfers the brake disc 1 to the second dressing mechanism 24 and places it horizontally on the brake disc support device 245, where the outer edge of the brake disc is held by the jaws 24522. Then, the second deburring device 241 and the inner edge grinding device 242 operate simultaneously. The first lateral moving structure and the second lateral moving structure can simultaneously drive the deburring assembly 2412 and the inner edge grinding assembly 2422 to move laterally relative to each other, so that the second deburring grinding wheel 24122 and the inner edge grinding wheel 24222 reach above the brake disc 1, respectively. Subsequently, the first lifting structure and the second lifting structure simultaneously drive the deburring assembly 2412 and the inner edge grinding assembly 24222 to descend, so that the second deburring grinding wheel 24122 and the inner edge grinding wheel 24222 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.

[0162] Subsequently, the transfer robot 22 transfers the brake disc 1 to the claw 26431 of the rotating mechanism 264. The push block 271 of the positioning mechanism 27 pushes the brake disc into place, and then the outer edge grinding mechanism 25 performs outer edge grinding. Specifically, the first grinding wheel 25121 and the second grinding wheel 25131 of the outer edge grinding device 251 are driven by the transverse drive device 253 along the edge. Figure 19 The arrow in the image approaches the outer edge 11, causing the first grinding wheel 25121 to perform the first grinding on the outer edge 11 to form the first step structure A1, thus presenting... Figure 20 The state shown. Next, within a preset time interval, the second grinding wheel 25131 descends to a preset position determined according to the grinding amount under the drive of the lifting drive structure 2514. Simultaneously, the first grinding wheel 25121 and the second grinding wheel 25131 move along the path driven by the forward and backward drive device 252. Figure 20 The second grinding wheel 25131 moves in the direction of the arrow to contact the outer edge 11 for a second grinding process, thereby forming... Figure 21 The second step structure A2 is shown. Then, the first grinding wheel 25121 and the second grinding wheel 25131 move along the path driven by the forward and backward drive device 252. Figure 21 Move in the direction of the arrow until the outer edge is ground.

[0163] Next, the rotating support 2642 rotates 90° counterclockwise under the drive of the rotating table 26411, rotating the brake disc, which has completed the outer edge grinding operation, to the first toroidal grinding device 261. Then, the thickness detection device 267 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 267 rises to a position that does not interfere with the grinding operation. The first toroidal grinding wheel 26111 and the second toroidal grinding wheel 26121 move towards each other under the drive of the second drive device 266, and then approach the rotating mechanism 264 under the drive of the first drive device 265, thereby performing one-third of the overall toroidal grinding operation on the brake disc 1. Afterwards, the rotating support 2642 rotates 90° counterclockwise again under the drive of the rotating table 26411 to rotate the brake disc to the second toroidal grinding device 262. After completing two-thirds of the overall toroidal grinding operation, the rotating support 2642 rotates 90° counterclockwise again to move the brake disc to the third toroidal grinding device 263 to complete the remaining one-third of the toroidal grinding operation. After the toroidal grinding operation is completed, the transfer robot 22 transfers the completed brake disc to the unloading conveyor 29 for unloading.

[0164] In summary, the multi-station brake disc grinding equipment provided in this application automates the deburring process of the brake disc and improves grinding efficiency by setting a pretreatment area on the base and including a first dressing mechanism for deburring the first annular surface of the brake disc and a second dressing mechanism for deburring the second annular surface and grinding the inner edge within the pretreatment area. Furthermore, by performing the deburring of the second annular surface and the inner edge grinding simultaneously, the processing time of the brake disc is further reduced.

[0165] The multi-station brake disc grinding equipment of this application integrates inner edge grinding, outer edge grinding, and toroidal grinding operations on the same grinding equipment by setting up a second dressing mechanism, an outer edge grinding mechanism, and a toroidal grinding mechanism, thereby further improving the grinding efficiency of the brake disc. Furthermore, by setting up a rotary mechanism for transfer between the three toroidal grinding devices and the outer edge grinding device, this application achieves the connection between the outer edge grinding operation and the toroidal grinding operation, ensuring automated, continuous, assembly-line grinding of the brake disc.

[0166] The above embodiments are merely illustrative of the inventive essence and beneficial effects of this application, and are not intended to limit this application. 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.
