Technical Field

[0001] The present invention relates to the field of brake pad processing, and particularly to a processing and treatment device for automotive brake pads. Background Art

[0002] An automotive brake pad grinding device is a special equipment for processing and repairing the surface precision of brake pads. Its core function is to ensure that the flatness, thickness, and friction performance of the contact surface between the brake pad and the brake disc meet the design requirements through high-precision grinding technology. It plays a key role in the production and manufacturing process of automotive brake pads, helps to improve the quality and reliability of brake pads, and ensures the safe and stable operation of the automotive braking system;

[0003] A Chinese patent with the publication number CN115533641B discloses a grinding device for automotive brake pads, which includes a number of brake pads and a rotating disc. There are a number of mounting grooves on the upper side of the rotating disc. A through hole is provided inside the mounting groove, and a mounting shell is provided inside the through hole. A mounting ring is detachably arranged inside the mounting groove. A support plate is provided on the right side of the rotating ring, and a top plate is fixed to the upper end of the left side of the support plate. A clamping device is provided between the mounting ring and the brake pad. A rotating mechanism is provided on the lower side of the rotating disc, and a grinding mechanism is provided between the rotating disc and the top plate.

[0004] Although this patent installs a fixture on the mounting shell and the mounting ring for clamping the brake pad for processing, the rotating disc rotates to bring the fixture to the processing area for processing, and multiple fixtures are installed on the rotating disc, enabling the replacement of the brake pad to be operated outside the processing area, improving the safety of the equipment. However, when grinding the brake pad, this patent performs single-pass grinding and cannot grind layer by layer, resulting in excessive instantaneous pressure on the grinding wheel and reducing its service life. Summary of the Invention

[0005] The main object of the present invention is to provide a processing and treatment device for automotive brake pads, which can effectively solve the technical problems in the background art.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:

A circular groove is provided through the top and bottom of the heightening block. A second pulley is fixedly connected to the top of the heightening block. A second pulley is also rotatably connected to the top of the column in the lower left corner of the bottom plate. Moreover, two interconnected second pulleys are rotatably connected to the tops of the two columns in the upper left and upper right corners of the bottom plate respectively. A wide belt is sleeved between two adjacent second pulleys at the same height.

[0014] As a further solution of the present invention, a working condition switching structure is provided on the top of the bottom plate. The working condition switching structure includes a pulley three and a lifting pulley. One side of the top of the bottom plate is fixedly connected with a fixing frame. The top of the fixing frame is fixedly connected with a supporting frame. The pulley three is rotatably connected to the top of the fixing frame. The lifting pulley is placed on the top of the pulley three. The top of the lifting pulley is fixedly connected with a lifting rod. The lifting rod penetrates through the top of the supporting frame. The top of the fixing frame and through the pulley three is rotatably connected with a driving cylinder. The inner wall of the driving cylinder is provided with a spiral driving groove.

[0018] The beneficial effects of the present invention are as follows:

[0019] By setting up a layer-by-layer grinding structure, layer-by-layer micro-grinding avoids single-pass over-cutting, ensures uniform thickness, and at the same time, the layered load dispersion reduces the instantaneous pressure of the grinding wheel, extends the service life, and also the layered load dispersion reduces the instantaneous pressure of the grinding wheel and extends the service life.

[0020] By setting up the support mode of the column, the sliding ring and the connecting rod, the stability of the connecting plate is enhanced, and the influence of vibration on the machining accuracy is reduced;

[0021] Four processing modes are realized through the working condition switching structure, covering the full-scenario requirements from high-precision single-piece processing to high-efficiency batch production, with both process flexibility, energy consumption controllability and equipment adaptability, meeting the technical requirements for the diversified production of automotive brake pads.

[0022] In working condition one, the four grinding wheels rotate clockwise synchronously to perform multi-directional and uniform grinding on a single brake pad, reducing single-point stress concentration, improving surface flatness, driving all grinding wheels synchronously, avoiding thickness deviation caused by different rotational speeds between the wheels, ensuring the same grinding depth for each layer, sharing the grinding force among the four grinding wheels, reducing the wear rate of a single grinding wheel, and extending the service life.

[0023] In working condition two, only one grinding wheel is enabled, which is suitable for small-batch or low-load processing scenarios, reducing energy consumption. Four brake pads are installed simultaneously and ground sequentially by a single grinding wheel, which is suitable for small-batch production of multiple varieties and improves the equipment utilization rate.

[0024] In working condition three, the four grinding wheels are synchronously matched with the four brake pads to achieve fully automated assembly line processing, greatly improving production capacity. All grinding wheels are driven synchronously to ensure high uniformity of parameters such as layer depth and surface roughness of multiple brake pads, completing four times the output per unit time, reducing the single-piece processing cost, and being suitable for large-scale standardized production.

[0025] In working condition four, the workbench triggers layer lowering once every 45 degrees of rotation. Four layers of grinding are completed in a single circle, achieving a denser inter-layer transition, improving the processing resolution. The high-frequency layer-lowering mode is suitable for progressive shaping of special-shaped brake pads, avoiding the risk of over-cutting.

[0026] During the movement of the grinding wheel, the hexagonal rod will be driven to rotate synchronously. And during this process, the hexagonal rod always passes through pulley two. Therefore, during the movement of the grinding wheel, pulley one can still be driven to rotate through the hexagonal rod, so that the grinding wheel will not stop rotating due to the change of position.

[0043] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0044] As Figure 1 - Figure 15 shown, a processing device for automobile brake pads includes a vertical frame 1. A bottom plate 2 is fixedly connected to the top of the vertical frame 1. An embedded groove 4 is opened on the top of the bottom plate 2. A working disk 3 is rotatably connected inside the embedded groove 4. Four pairs of fixing blocks 5 are symmetrically and fixedly connected to the top of the working disk 3. A cylinder 6 is fixedly connected to the side surface of each fixing block 5. The output shaft of the cylinder 6 penetrates through the side surface of the fixing block 5 and is fixedly connected to a clamping block 7. Four pairs of straight grooves 8 are symmetrically opened on the top of the working disk 3. The clamping block 7 is slidably connected with the straight groove 8. Four layer-by-layer grinding structures 9 are arranged on the top of the bottom plate 2;

[0045] The layer-by-layer grinding structure 9 includes a grinding wheel 11. A column 10 is fixedly connected to the top of the bottom plate 2. A through groove 19 is opened through the outer surface inside the column 10. A connecting plate 13 is slidably connected through the through groove 19 inside the column 10. The grinding wheel 11 is rotatably connected to the bottom of the connecting plate 13 near one end. Two belt pulleys 17 are rotatably connected to the top of the connecting plate 13. A first belt 18 is sleeved between the two belt pulleys 17. A lead screw 20 is rotatably connected to the top of the bottom plate 2 and inside the column 10. A large turntable 21 is rotatably connected to the bottom of the vertical frame 1. A small turntable 23 is rotatably connected to the bottom of the vertical frame 1. Four pairs of threaded grooves are opened on the bottom of the large turntable 21. A toggle rod 22 is threadedly connected to the top of the large turntable 21 through a pair of threaded grooves. Two toggle blocks 24 are symmetrically arranged on the bottom of the small turntable 23.

[0046] Place the automobile brake pad between a pair of clamping blocks 7, and then synchronously start the two cylinders 6 to drive the pair of clamping blocks 7 to slide close to each other along the two straight grooves 8, so as to clamp and fix the automobile brake pad. At this time, rotate the working disk 3, and the automobile brake pad can be driven to rotate together. At the same time, rotate the belt pulley 17 and drive the two belt pulleys 17 to rotate together through the first belt 18. Therefore, when the automobile brake pad rotates to the position of the grinding wheel 11, the top of the automobile brake pad can be ground;

[0047] Rotate the large turntable 21 to drive the working plate 3 and the toggle lever 22 to rotate together. When the toggle lever 22 rotates to the position of the small turntable 23, the toggle lever 22 will squeeze the two toggle blocks 24. At the same time, since one end of the toggle lever 22 is in a pear shape, when the toggle lever 22 squeezes the toggle block 24, it will force the two toggle blocks 24 and the small turntable 23 to rotate together. Therefore, when the automotive brake pad rotates past the grinding wheel 11, the toggle lever 22 will drive the small turntable 23 to rotate, thereby driving the lead screw 20 to rotate together. After the lead screw 20 rotates, it will drive the connecting plate 13 and the grinding wheel 11 to descend one layer along the through groove 19. Therefore, when the automotive brake pad rotates one circle and is ground by one layer, the grinding wheel 11 descends one layer to continue grinding the top of the automotive brake pad. Therefore, the effect of layer-by-layer grinding of the automotive brake pad is achieved.

[0048] In this embodiment, the connecting plate 13 is threadedly connected to the lead screw 20, and the top of the lead screw 20 penetrates through the top of the first pulley 17.

[0049] In this embodiment, three lifting grooves 12 are equidistantly arranged on the outer surface of the column 10. A sliding ring 14 is slidably connected to the outer surface of the column 10 through the three lifting grooves 12. Connecting blocks 15 are fixedly connected to the outer surface of the sliding ring 14 and the top of the connecting plate 13 respectively. Two connecting rods 16 are rotatably connected between the two connecting blocks 15;

[0050] During the process of the connecting plate 13 descending, it will drive the bottom connecting block 15 to descend together, thereby driving the top connecting block 15 and the sliding ring 14 to slide downward along the three lifting grooves 12 through the two connecting rods 16. Through the friction force between the two connecting rods and the sliding ring 14 and the lifting grooves 12, the top of the connecting plate 13 is supported to improve the stability of the connecting plate 13.

[0051] In this embodiment, a screw rod 27 is threadedly connected to the bottom of the small turntable 23. The toggle block 24 is rotatably connected to the outer surface of the screw rod 27. One end of the toggle lever 22 is in a pear shape, and one end of the toggle lever 22 is adaptively matched with the two toggle blocks 24.

[0052] In this embodiment, a connecting frame 25 is fixedly connected to the bottom of the vertical frame 1. A first motor 26 is fixedly connected to the bottom of the connecting frame 25. The output shaft of the first motor 26 is fixedly connected to the center position of the bottom of the large turntable 21;

[0053] Start the first motor 26, which can drive the large turntable 21 to rotate together, thereby driving the layer-by-layer grinding structure 9 to operate. At the same time, the connecting frame 25 is fixedly connected to both sides of the vertical frame 1 and has no connection relationship with the bottom of the vertical frame 1. Therefore, the connecting frame 25 will not block the toggle lever 22.

[0054] In this embodiment, a heightening block 32 is rotatably connected to the top of the column 10 at the lower right corner of the bottom plate 2. A circular groove is formed through the top of the heightening block 32. A second pulley 29 is fixedly connected to the top of the heightening block 32. A second pulley 29 is also rotatably connected to the top of the column 10 at the lower left corner of the bottom plate 2. Moreover, two interconnected second pulleys 29 are rotatably connected to the tops of the two columns 10 at the upper left and upper right corners of the bottom plate 2 respectively. A wide belt 30 is sleeved between two adjacent second pulleys 29 at the same height.

[0055] In this embodiment, a working condition switching structure 28 is provided on the top of the bottom plate 2. The working condition switching structure 28 includes a third pulley 33 and a lifting pulley 34. A fixing frame 38 is fixedly connected to one side of the top of the bottom plate 2. A support frame 36 is fixedly connected to the top of the fixing frame 38. The third pulley 33 is rotatably connected to the top of the fixing frame 38. The lifting pulley 34 is placed on the top of the third pulley 33. A lifting rod 35 is fixedly connected to the top of the lifting pulley 34. The lifting rod 35 penetrates through the top of the support frame 36. A driving cylinder 40 is rotatably connected to the top of the fixing frame 38 and penetrates through the third pulley 33. A spiral driving groove 45 is formed in the inner wall of the driving cylinder 40. An upper top block 42 is slidably connected to the inside of the driving cylinder 40. A driving block 44 is fixedly connected to the outer surface of the upper top block 42. A sliding rod 43 is fixedly connected to the top of the upper top block 42. A wide belt 30 is also sleeved between the third pulley 33 and the second pulley 29 near the lower left corner of the bottom plate 2. A narrow belt 31 is sleeved between the lifting pulley 34 and the adjacent second pulley 29 at the same level. The top of the sliding rod 43 is fixedly connected to the bottom of the lifting pulley 34;

[0056] Working condition one: From Figure 13 it can be seen that the spiral driving groove 45 is right-handed. Therefore, at this time, when the driving cylinder 40 is rotated clockwise, the spiral driving groove 45 can be driven to rotate clockwise, thereby forcing the driving block 44 together with the upper top block 42 to move downward. However, at this time, since the driving block 44 is located at the bottom end of the spiral driving groove 45, when the driving cylinder 40 is rotated clockwise, the driving block 44 together with the upper top block 42 and the sliding rod 43 can be driven to rotate clockwise together, thereby driving the lifting pulley 34 to rotate. The rotation of the driving cylinder 40 can directly drive the third pulley 33 to rotate. Therefore, the third pulley 33 and the lifting pulley 34 rotate clockwise synchronously. At this time, through all the wide belts 30 and narrow belts 31, all the second pulleys 29 are driven to rotate clockwise synchronously. Then, in cooperation with the four hexagonal rods 39 and the first belt 18, all the first pulleys 17 can be driven to rotate clockwise synchronously. Therefore, the four grinding wheels 11 are driven to rotate clockwise synchronously. At this time, an automotive brake pad is fixed on the working disk 3 and can be ground layer by layer by the four grinding wheels 11. Therefore, when grinding an automotive brake pad, by synchronously driving the four grinding wheels 11, the grinding precision can be improved;

[0057] Working condition 2: rotating the drive cylinder 40 counterclockwise can drive the drive block 44 to move upward through the spiral drive groove 45, thereby driving the upper block 42 and the slide rod 43 to move upward, thereby driving the lifting pulley 34 and the lifting rod 35 to move upward, so that the slide rod 43 is no longer located inside the drive cylinder 40, so that the lifting pulley 34 cannot rotate, and only the pulley 33 rotates counterclockwise, so that only the pulley 29 near the lower right corner of the bottom plate 2 can rotate counterclockwise, so that only one grinding wheel 11 rotates counterclockwise, and at the same time, according to the threaded connection between the screw rod 27 and the small turntable 23, the three pairs of toggle blocks 24 on the three small turntables 23 are removed, so that the large turntable 21 rotates, and only one layer-by-layer grinding structure 9 can be toggled to operate through the toggle rod 22, so that the working disk 3 rotates, driving four automobile brake pads to rotate, and being ground by a grinding wheel 11;

[0058] Working condition three: rotating the driving cylinder 40 clockwise to drive the four layer-by-layer grinding structures 9 to operate, that is, the four grinding wheels 11 rotate clockwise synchronously, and at the same time, four automobile brake pads are fixed on the working disk 3. Rotating the working disk 3 can drive the four automobile brake pads to rotate synchronously, and the four grinding wheels 11 grind them layer by layer synchronously;

[0059] Working condition 4: four toggle rods 22 are installed through four pairs of threaded holes opened at the bottom of the large turntable 21, so that the large turntable 21 rotates forty-five degrees, which can start a small turntable 23 to rotate one circle. At this time, a car brake pad is installed on the working disk 3, so that the working disk 3 rotates forty-five degrees, and one layer can be ground. The working disk 3 rotates one circle, so that the car brake pad is ground four layers.

[0060] In this embodiment, a through groove 46 is formed inside the column 10 through the top, the top of the pulley 17 is through the through groove 46 and the top is fixedly connected with a hexagonal rod 39, the hexagonal rod 39 passes through the pulley 29 and the hexagonal rod 39 also passes through the circular groove, the diameter of the hexagonal rod 39 is smaller than the diameters of the through groove 46 and the circular groove, the bottom of the hexagonal rod 39 is formed through the bottom, and the top of the screw rod 20 is slidably connected to the inside of the bottom groove 41;

[0061] During the movement of the grinding wheel 11, the hexagonal rod 39 will be driven to rotate synchronously, and during this process, the hexagonal rod 39 always penetrates the pulley 29. Therefore, during the movement of the grinding wheel 11, the pulley 17 can still be driven to rotate through the hexagonal rod 39, so that the grinding wheel 11 will not stop rotating due to the change of position.

[0062] In this embodiment, the driving block 44 is located inside the spiral driving groove 45 and close to the bottom end, and the top end and the bottom end of the spiral driving groove 45 differ by 180 degrees.

[0063] In this embodiment, the bottom of the fixing frame 38 is fixedly connected to the motor 2 37 , and the output shaft of the motor 2 37 is fixedly connected to the bottom of the driving cylinder 40 .

[0064] It should be noted that the present invention is a processing device for automobile brake pads. When in use, the automobile brake pad is placed between a pair of clamping blocks 7, and then two cylinders 6 are synchronously started to drive the pair of clamping blocks 7 to slide close to each other along two straight grooves 8, so that the automobile brake pad is clamped and fixed. At this time, the working disk 3 is rotated to drive the automobile brake pad to rotate together, and the pulley 17 is rotated at the same time, and the two pulleys 17 are driven to rotate together through the belt 18, so that when the automobile brake pad is rotated to the position of the grinding wheel 11, the top of the automobile brake pad can be ground;

[0065] The large turntable 21 is rotated to drive the working disc 3 and the toggle rod 22 to rotate together. When the toggle rod 22 is rotated to the position of the small turntable 23, the toggle rod 22 will be squeezed with the two toggle blocks 24. At the same time, since one end of the toggle rod 22 is pear-shaped, the toggle rod 22 will force the two toggle blocks 24 to rotate together with the small turntable 23 when squeezing with the toggle block 24. Therefore, when the automobile brake pad rotates through the grinding wheel 11, the toggle rod 22 will drive the small turntable 23 to rotate, thereby driving the screw rod 20 to rotate together. After the screw rod 20 rotates, it will drive the connecting plate 13 and the grinding wheel 11 to descend one layer along the through groove 19. Therefore, when the automobile brake pad rotates one circle and is ground one layer, the grinding wheel 11 descends one layer to continue grinding the top of the automobile brake pad, thereby achieving the effect of grinding the automobile brake pad layer by layer.

[0066] When the connecting plate 13 descends, the connecting block 15 at the bottom will be driven to descend together, so that the connecting block 15 near the top and the slip ring 14 are driven to slide downward along the three lifting grooves 12 through the two connecting rods 16. The friction between the two connecting rods and the slip ring 14 and the lifting grooves 12 supports the top of the connecting plate 13, thereby improving the stability of the connecting plate 13.

[0067] Starting the motor 1 26 can drive the large turntable 21 to rotate together, thereby driving the layer-by-layer grinding structure 9 to operate. At the same time, the connecting frame 25 is fixedly connected to both sides of the vertical frame 1 and has no connection with the bottom of the vertical frame 1. Therefore, the connecting frame 25 will not block the toggle rod 22;

[0068] Working condition 1: Figure 13It can be seen that the spiral driving groove 45 is right-handed. Therefore, at this time, rotating the driving cylinder 40 clockwise can drive the spiral driving groove 45 to rotate clockwise, thereby forcing the driving block 44 and the upper top block 42 to move downward. However, since the driving block 44 is located at the bottom end of the spiral driving groove 45 at this time, rotating the driving cylinder 40 clockwise can drive the driving block 44, the upper top block 42 and the sliding rod 43 to rotate clockwise together, thereby driving the lifting pulley 34 to rotate. The rotation of the driving cylinder 40 can directly drive the pulley three 33 to rotate. Therefore, the pulley three 33 and the lifting pulley 34 are The wheel 34 rotates synchronously clockwise, and at this time, all the wide belts 30 and the narrow belts 31 drive all the pulleys 29 to rotate synchronously clockwise, so that in combination with the four hexagonal rods 39 and the belt 18, all the pulleys 17 can be driven to rotate synchronously clockwise, thereby driving the four grinding wheels 11 to rotate synchronously clockwise. At this time, a car brake pad is fixed on the working disk 3, and can be ground layer by layer by the four grinding wheels 11. Therefore, when grinding a car brake pad, the grinding accuracy can be improved by synchronously driving the four grinding wheels 11;

[0069] Working condition 2: rotating the drive cylinder 40 counterclockwise can drive the drive block 44 to move upward through the spiral drive groove 45, thereby driving the upper block 42 and the slide rod 43 to move upward, thereby driving the lifting pulley 34 and the lifting rod 35 to move upward, so that the slide rod 43 is no longer located inside the drive cylinder 40, so that the lifting pulley 34 cannot rotate, and only the pulley 33 rotates counterclockwise, so that only the pulley 29 near the lower right corner of the bottom plate 2 can rotate counterclockwise, so that only one grinding wheel 11 rotates counterclockwise, and at the same time, according to the threaded connection between the screw rod 27 and the small turntable 23, the three pairs of toggle blocks 24 on the three small turntables 23 are removed, so that the large turntable 21 rotates, and only one layer-by-layer grinding structure 9 can be toggled to operate through the toggle rod 22, so that the working disk 3 rotates, driving four automobile brake pads to rotate, and being ground by a grinding wheel 11;

[0070] Working condition three: rotating the driving cylinder 40 clockwise to drive the four layer-by-layer grinding structures 9 to operate, that is, the four grinding wheels 11 rotate clockwise synchronously, and at the same time, four automobile brake pads are fixed on the working disk 3. Rotating the working disk 3 can drive the four automobile brake pads to rotate synchronously, and the four grinding wheels 11 grind them layer by layer synchronously;

[0071] Working condition 4: four toggle rods 22 are installed through four pairs of threaded holes opened at the bottom of the large turntable 21, so that the large turntable 21 rotates forty-five degrees, and a small turntable 23 can be started to rotate one circle. At this time, a car brake pad is installed on the working disk 3, so that the working disk 3 rotates forty-five degrees, and one layer can be ground. The working disk 3 rotates one circle, so that the car brake pad is ground four layers;

[0072] During the movement of the grinding wheel 11, the hexagonal rod 39 will be driven to rotate synchronously. And during this process, the hexagonal rod 39 always passes through the second belt pulley 29. Therefore, during the movement of the grinding wheel 11, the first belt pulley 17 can still be driven to rotate through the hexagonal rod 39, so that the grinding wheel 11 will not stop rotating due to the change of position.
