Description

Technical Field

[0001] The invention relates to the technical field of brake disc processing, and in particular to a grinding device for brake disc processing. Background Art

[0002] In the brake disc processing industry, grinding is a key link to improve the surface quality of the brake disc and ensure stable braking performance. Traditionally, the grinding of brake discs relies mostly on manual operations or simple semi-automatic equipment, which have many shortcomings.

[0003] In the prior art, a common grinding device for brake disc processing uses a handheld grinding tool, and the worker directly controls the grinding head to grind the surface of the brake disc. Although this method is flexible, it is highly dependent on the worker's operating skills and experience, resulting in difficulty in ensuring the grinding quality, and there are problems such as uneven grinding, easy scratches and excessive wear. In addition, manual grinding is inefficient and labor-intensive, and it is difficult to meet the needs of large-scale production.

[0004] Another more advanced existing technology is to use partially mechanized grinding equipment. These devices usually achieve the reciprocating motion of the grinding head through a simple mechanical structure. Although this improves the grinding efficiency and stability to a certain extent, it still has many defects. For example, these devices often lack precise pressure control mechanisms, resulting in excessive impact force due to instantaneous contact in the initial stage of grinding, which can easily damage the brake disc surface or leave scratches. At the same time, the degree of automation of the equipment is limited, and more manual intervention and monitoring are required, which not only increases labor intensity but also reduces production efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] A series of mechanical linkage structures driven by the driving motor realize the reciprocating and uniform grinding of the brake disc body by the surface grinding parts. This mechanized grinding method is more precise and stable than manual operation, which effectively improves the grinding efficiency and quality. A smaller initial pressure is set at the initial stage of grinding to avoid damage or scratches on the brake disc surface caused by excessive impact force generated by instantaneous contact. As the grinding process proceeds, the pressure is gradually increased to ensure that the brake disc surface can be polished evenly and smoothly, effectively preventing excessive wear and uneven scratches. The combination of damping springs and counterweights is used to realize automatic resetting and cyclic movement of the sliding block, moving block and connecting rod. This design not only simplifies the operation process, but also improves the degree of automation of the equipment and the continuity of grinding, reducing the need for manual intervention.

[0019] Through the precise correspondence between the top column, the clamping rod and the mounting hole of the brake disc body, and the lifting mechanism driven by the first cylinder, the brake disc body can be installed quickly and accurately. The interference fit between the spline rod and the spline groove, and the synergistic effect of the pressure column and the top column ensure that the brake disc body is firmly fixed during the grinding process, avoiding the problem of uneven grinding caused by shaking or displacement. The design of the liquid collecting tank, drain hole and collection chamber enables the coolant generated during the grinding process to be effectively collected and discharged, which not only keeps the working area clean, but also helps to cool and lubricate the grinding surface, reduce heat accumulation and friction loss, and the control valve on the drain pipe allows flexible control of the discharge of the coolant, improving the practicality and convenience of the system.

[0020] By starting the second cylinder to drive the U-shaped frame to move laterally on the first crossbar, the surface grinding piece can be accurately positioned just above and just below the brake disc body, ensuring the accuracy and efficiency of grinding. At the same time, this design also provides flexible adjustment space to adapt to brake discs of different specifications and models. During the grinding process, the airbag is squeezed and extracted by the lateral reciprocating movement of the pressure plate 732, so that the automatic extraction and spraying of the coolant is realized, which not only effectively reduces the high temperature of the brake disc body caused by grinding, prevents thermal damage and deformation, but also prolongs the service life of the grinding piece and the brake disc. At the same time, the spraying of the coolant also helps to lubricate the grinding surface and reduce friction and wear. When the first crossbar rotates, the interaction between the gear and the ring gear realizes the self-rotation of the gear and drives the synchronous rotation of the synchronous pulley. This synchronous transmission mechanism ensures the stability and consistency of the grinding assembly during rotation, improves the grinding efficiency and quality. At the same time, the design of the bevel gear set enables the transmission column to drive the pressure plate to move laterally back and forth, further enhancing the flexibility and comprehensiveness of grinding.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: Combination Figure 1-Figure 10As shown, the present invention provides a technical solution: a grinding device for brake disc processing, comprising a box body 1 and a brake disc body 3, a placing table 2 is arranged on the top of the box body 1, the placing table 2 is used to place the brake disc body 3, the brake disc body 3 is connected to the top of the placing table 2, in order to fix the brake disc body 3, a fixing frame 4 is arranged on one side of the box body 1, a moving frame 5 is installed on the fixing frame 4, a first cross bar 6 is connected to one side of the moving frame 5, a grinding assembly 7 is arranged on the first cross bar 6, and is used to grind the upper and lower surfaces of the brake disc body 3;

[0034] The grinding assembly 7 includes a U-shaped frame 71 slidably mounted on the first crossbar 6, the inner side end of the U-shaped frame 71 is fixedly connected to a guide rod 736, the upper and lower ends of the guide rod 736 are slidably connected to a surface grinding piece 735, and the inner cavity of the U-shaped frame 71 is fixedly connected to positioning rods 72 on both sides, and the upper and lower ends of the positioning rods 72 are slidably connected to a sliding block 73 fixedly connected to the surface grinding piece 735. In order to enable the sliding block 73 to move smoothly, the outer wall of the positioning rod 72 is provided with a damping spring 737 located at the inner side end of the sliding block 73. In order to push the surface grinding piece 735 to move toward the surface of the brake disc body 3, intermittent pushing members are provided on both sides of one end of the sliding block 73.

[0035] The intermittent pusher includes two rotating rods 75 rotatably mounted on the inner wall of the U-shaped frame 71 through a rotating shaft, and the two rotating shafts are connected through a pulley transmission member 77. One end of one of the rotating rods 75 is provided with a driving motor 76, and the other ends of the two rotating rods 75 are rotatably connected with a V-shaped rod 78, and the other ends of the V-shaped rod 78 are rotatably connected with a connecting rod 710, and the other end of the connecting rod 710 is rotatably mounted on the U-shaped frame 71, and the middle position of the V-shaped rod 78 is rotatably connected with a moving rod 79, and a row of pushing blocks 711 for pushing the sliding block 73 to move are provided on the top of the moving rod 79;

[0036] In order to enable the sliding block 73 to move smoothly, a moving block 74 corresponding to the pushing block 711 is provided at the bottom of the sliding block 73, a connecting rod 715 is fixedly connected to one side of the moving block 74, a second cross bar 712 fixedly installed on the U-shaped frame 71 is provided on one side of the moving rod 79, a row of stoppers 713 are provided on the top of the second cross bar 712, the stoppers 713 are rotatably installed on the second cross bar 712, and a counterweight block 714 is fixedly connected to one side of the bottom end of the stopper 713. Under the action of its own gravity, the counterweight block 714 can be pressed on the second cross bar 712 and drive the stopper 713 to tilt to one side;

[0037] A water tank 725 is fixedly installed inside the U-shaped frame 71, and a water inlet pipe 726 is arranged on one side of the water tank 725. In order to support the water tank 725, a bracket 727 fixedly installed on the U-shaped frame 71 is arranged above the water tank 725. A driving shaft 728 is rotatably connected to one side of the bracket 727, and a transmission column 730 is fixedly connected to the outer wall of the driving shaft 728. A reciprocating groove 731 is opened on the outer wall of the transmission column 730. An extraction airbag 723 is arranged on the other side of the bracket 727, and a pressure plate 732 is arranged on the other side of the extraction airbag 723. A moving plate 733 is arranged at the other end of the extraction airbag 723, and a sliding column 734 slidably installed in the reciprocating groove 731 is arranged at the other end of the moving plate 733.

[0038] A transmission pipe 722 is connected to the water outlet of the extraction airbag 723, and a connecting pipe 721 is connected to the other end of the transmission pipe 722. Both ends of the connecting pipe 721 are connected to delivery pipes 719, and the two delivery pipes 719 are fixedly installed on the U-shaped frame 71 and are located on both sides of the surface polishing member 735. A row of nozzles 720 are arranged on the top of the delivery pipe 719. An extraction pipe 724 is connected to the water inlet of the extraction airbag 723, and the tail end of the extraction pipe 724 is located inside the water tank 725.

[0039] The top of the U-shaped frame 71 is rotatably connected to a transmission rod 716 , the upper end of the transmission rod 716 is fixedly connected to a second synchronous pulley 717 , and the bottom end is transmission-connected to a drive shaft 728 via a bevel gear set 729 .

[0040] In the embodiment of the present invention, when the driving motor 76 is started, its power is synchronously transmitted to the rotating rod 75 to drive it to rotate. This action further causes another rotating rod 75 to rotate synchronously through the clever cooperation of the pulley transmission member 77. During the movement, the rotating rod 75 closely cooperates with the connecting rod 710 and the V-shaped rod 78 to drive the moving rod 79 to reciprocate. During the reciprocating process of the moving rod 79, a harmonious interaction is formed with the pushing block 711. The pushing block 711 moves back and forth accordingly, and together with the moving block 74, guides the sliding block 73 and the surface polishing member 735 on its surface, so that they slide inward along the positioning rod 72, and at the same time compresses the damping spring 737;

[0041] In the process of the sliding block 73 and the moving block 74 moving inward, the connecting rod 715 also moves synchronously. It is particularly noteworthy that when the connecting rod 715 moves from one block 713 to another block 713, its kinetic energy is sufficient to drive the block 713 to rotate, and when the connecting rod 715 moves to the inner side of the second block 713, the first block 713 will be reset under the gravity of the counterweight block 714. At this time, the elastic force of the damping spring 737 begins to play a role, pushing the sliding block 73 to move outward. At this time, the block 713 will play a blocking role, ensuring that the sliding block 73, the moving block 74 and the connecting rod 715 reciprocate at their set positions;

[0042] Before the grinding process begins, we need to ensure that an appropriate initial gap is maintained between the two surface grinding pieces 735 and the upper and lower surfaces of the brake disc body 3 to reduce the impact force at the moment of contact. When the surface grinding piece 735 first contacts the brake disc body 3, pressure should be gradually applied to make it lightly fit on the surface of the brake disc body 3. This initial pressure must be strictly controlled to avoid excessive wear or uneven scratches on the brake disc surface. As the grinding process progresses, we can gradually increase the pressure of the surface grinding piece 735 on the brake disc body 3, but this increase process must be gradual to ensure that the surface of the brake disc body 3 can be evenly and smoothly ground.

[0043] While increasing the pressure, we should closely observe the changes on the brake disc surface to ensure that the grinding effect reaches the expected result. If the brake disc surface is found to be uneven or the scratches are too deep, the pressure should be adjusted immediately to ensure the smooth progress of the grinding work.

[0044] Embodiment 2: Combination Figure 2 , Figure 3 As shown, on the basis of the first embodiment, the movable frame 5 includes a device capable of sliding in the vertical direction, which is a lifting plate 51 mounted on the fixed frame 4. A component called a first cylinder 56 is mounted on the top of the lifting plate 51, and this component is also mounted on the top of the fixed frame 4. A servo motor is fixedly connected to the bottom of the lifting plate 51, and the output end of the servo motor is fixedly connected to the movable plate 52. In addition, a component called a first cross bar 6 is fixedly installed on the movable plate 52, and a pressure column 53 is rotatably connected to the bottom of the movable plate 52. A component called a spline rod 54 is fixedly installed at the bottom of the pressure column 53. A component called a gear ring 55 is also provided on the side wall of the lifting plate 51;

[0045] In the inner cavity of the box body 1, a space called a collecting chamber 11 is opened, and at the top of the box body 1, a space called a collecting tank 12 is opened, and this space is located outside the placement table 2. At the position of the collecting tank 12, a drainage hole 13 connected to the collecting chamber 11 is opened, and at the bottom of one side of the box body 1, a drainage pipe 14 is opened;

[0046] A component called a top column 21 is fixedly connected to the top of the placement table 2. A spline groove 22 that is compatible with the spline rod 54 is opened on the top of the top column 21. A clamping rod 23 for installing the brake disc body 3 is set on the outside of the spline groove 22. This clamping rod 23 is mainly used for the connection and engagement of the brake disc body 3.

[0047] In the embodiment of the present invention, the brake disc body 3 needs to be accurately installed on the top column 21. During this process, it is necessary to ensure that the mounting hole on the brake disc body 3 and the clamping rod 23 can accurately correspond to each other, thereby ensuring the accuracy and stability of the entire installation process.

[0048] Next, the operator needs to start the first cylinder 56, which will cause the lifting plate 51, the first crossbar 6, and the grinding assembly 7, the movable plate 52, the pressure column 53, and the spline rod 54 installed on the first crossbar 6 to move downward together. The main purpose of this action is to allow the spline rod 54 to smoothly enter the spline groove 22, thereby forming an interference fit. In this process, as the pressure column 53 moves downward, it can closely cooperate with the top column 21, so that the brake disc body 3 is firmly installed on the top column 21. At this time, the two surface grinding pieces 735 are respectively located above and below the outer side of the brake disc body 3, which is fully prepared for the next grinding work;

[0049] Subsequently, the operator needs to turn on the servo motor, which will drive the movable disc 52, the first crossbar 6 and the grinding assembly 7 to rotate synchronously. Through this step, the grinding assembly 7 can perform a comprehensive grinding process on the upper surface, the lower surface and the side wall of the brake disc body 3 placed on the placement table 2 during the rotation process, thereby ensuring the flatness and friction coefficient of the brake disc body;

[0050] During the grinding process, the collecting trough 12 and the drain hole 13 play a vital role. They are responsible for collecting the coolant generated during use and discharging it into the collecting chamber 11. In order to better control the flow of the coolant, a control valve is installed on the drain pipe 14. When the used coolant in the collecting chamber 11 needs to be discharged, the drain pipe 14 will play a role to ensure the cleanliness of the working environment and the normal operation of the equipment. This series of precise operations and the coordination of components jointly ensure the accuracy and efficiency of the grinding of the brake disc body.

[0051] Example 3: Combination Figure 2 , Figure 4 , Fig. 9 As shown, on the basis of Example 2, a second cylinder 61 is fixedly installed on the inner end of the first cross bar 6, and the output end of the second cylinder 61 is fixedly connected to the U-shaped frame 71, a rotating shaft is rotatably connected to one side of the first cross bar 6, and the upper and lower ends of the rotating shaft are respectively fixedly connected to a gear 62 and a first synchronous pulley 63, one side of the gear 62 is meshed with the gear ring 55, a third cylinder 64 is fixedly connected to the side wall of the first cross bar 6, a tensioning pulley 65 is provided on the output end of the third cylinder 64, and the tensioning pulley 65, the first synchronous pulley 63, and the second synchronous pulley 717 are transmission connected through the third synchronous pulley 718.

[0052] In the embodiment of the present invention, by starting the second cylinder 61, the U-shaped frame 71 can be driven to move laterally on the first cross bar 6, and the U-shaped frame 71 can be moved to the position of the brake disc body 3, so that the two surface grinding parts 735 are respectively located directly above and directly below the brake disc body 3. When the U-shaped frame 71 moves, the second synchronous pulley 717 will also move accordingly. At this time, the third cylinder 64 is started to drive the tensioning wheel 65 to move, and the third synchronous pulley 718 is tensioned. When the first cross bar 6 rotates, due to the action of the gear 62 and the ring gear 55, the gear 62 rotates with the rotation of the first cross bar 6, which enables the gear 62 to drive the first synchronous pulley 63 to rotate synchronously, and then the first synchronous pulley 63 can cooperate with the tensioning wheel 65 to drive the second synchronous pulley 717 to rotate synchronously. Therefore, the second synchronous pulley 717 can cooperate with the transmission rod 716 and the bevel gear set 729 to rotate, and then drive the drive shaft 728 and the transmission column 730 to rotate synchronously through the bevel gear set 729, so that the transmission column 730 can cooperate with the reciprocating groove 731, the sliding column 734 and the movable plate 733 to drive the pressure plate 732 to perform lateral reciprocating movement. In the process of reciprocating movement, the pressure plate 732 will squeeze the extraction airbag 723, so that the extraction airbag 723 is affected by the squeezing, and the extraction pipe 724 is used to transport the coolant inside the water tank 725 to the transmission pipe 722, and the transmission pipe 722 transports the coolant to the connecting pipe 721 and the delivery pipe 719. These pipes use the nozzle 720 to spray the coolant on the brake disc body 3, thereby avoiding the situation where the brake disc body 3 is damaged by excessive temperature due to grinding.

[0053] Working principle of grinding equipment for brake disc processing:

[0054] Step 1, install the brake disc body 3 on the top column 21, and the mounting hole of the brake disc body 3 corresponds to the clamping rod 23, and the lifting plate 51, the first cross bar 6, the grinding assembly 7 installed on the first cross bar 6, the movable plate 52, the pressure column 53, and the spline rod 54 are driven downward by turning on the first cylinder 56, so that the spline rod 54 enters the spline groove 22 to form an interference fit, and the brake disc body 3 can be fixedly installed on the top column 21 by cooperating with the top column 21 during the downward movement of the pressure column 53, so that the two surface grinding parts 735 are respectively located above and below the outer side of the brake disc body 3, and then the movable plate 52, the first cross bar 6 and the grinding assembly 7 are driven to rotate synchronously by turning on the servo motor;

[0055] Step 2, by turning on the second cylinder 61 at the same time, the U-shaped frame 71 can be driven to move horizontally on the first cross bar 6, so that the U-shaped frame 71 can be moved to the position of the brake disc body 3, so that the two surface grinding members 735 are respectively located directly above and directly below the brake disc body 3, and the rotating rod 75 is driven to rotate synchronously by turning on the driving motor 76. The rotating rod 75 cooperates with the pulley transmission member 77 to drive another rotating rod 75 to rotate synchronously, and the rotating rod 75 cooperates with the connecting rod 710 to drive the moving rod 79 to move back and forth through the V-shaped rod 78, so that the moving rod 79 cooperates with the pushing block 711 to move back and forth during the reciprocating movement, so that the pushing block 711 cooperates with the moving block 74 to push the sliding block 73 and the surface grinding member 735 located on the positioning rod 72 to slide inward, and The damping spring 737 is compressed, and when the sliding block 73 and the moving block 74 move inward, the connecting rod 715 can be driven to move synchronously. When the connecting rod 715 moves from one block 713 to another block 713, the block 713 can be driven to rotate. When the connecting rod 715 moves to the inner side of another block 713, the previous block 713 is reset under the gravity of the counterweight block 714, and the sliding block 73 is pushed to move outward under the elastic force of the damping spring 737, and the block 713 blocks the sliding block 73, the moving block 74, and the connecting rod 715 at the moving position of the block 713, and so on and so forth, driving the sliding block 73 and the surface grinding piece 735 to move little by little toward the surface of the brake disc body 3 and perform grinding processing;

[0056] Step 3, when the U-shaped frame 71 moves, the second synchronous pulley 717 moves accordingly. At this time, the third cylinder 64 is turned on to drive the tensioning wheel 65 to move, so that the tensioning wheel 65 tensions the third synchronous pulley 718. When the first cross bar 6 rotates, due to the gear 62 and the gear ring 55, the gear 62 can rotate with the rotation of the first cross bar 6, so that the gear 62 drives the first synchronous pulley 63 to rotate synchronously, so that the first synchronous pulley 63 cooperates with the tensioning wheel 65 to drive the second synchronous pulley 717 to rotate synchronously, so that the second synchronous pulley 717 cooperates with the transmission rod 716 and the bevel gear set 729 to rotate, and then through the bevel gear set 729 The driving shaft 728 and the transmission column 730 are driven to rotate synchronously, so that the transmission column 730 cooperates with the reciprocating groove 731, the sliding column 734 and the movable plate 733 to drive the pressure plate 732 to move back and forth laterally, so that the pressure plate 732 squeezes the extraction airbag 723 during the reciprocating movement, so that the extraction airbag 723 is affected by the squeezing, and the extraction pipe 724 is used to transport the coolant inside the water tank 725 to the transmission pipe 722, and then the transmission pipe 722 transports the coolant to the connecting pipe 721 and the delivery pipe 719, so that the connecting pipe 721 and the delivery pipe 719 use the nozzle 720 to spray the coolant on the brake disc body 3, so as to avoid the brake disc body 3 being damaged by excessive temperature due to grinding.
