[0032] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0033] This application discloses an automatic grinding and polishing device for brake pads.

[0034] Reference Figure 1-5An automatic brake pad grinding and polishing device includes a device body 1. Inside the device body 1 is a first support plate 7 for support. Two symmetrical L-shaped support frames 6 are fixedly connected to both sides of the first support plate 7. Two vertical L-shaped support frames 6 form a group, with a total of two groups. A threaded rod 15 for transmitting rotation is rotatably connected between the left-hand group of L-shaped support frames 6. The rear end of the threaded rod 15 passes through the L-shaped support frame 6 and is fixedly connected to a first motor 5. The first motor 5 is fixedly connected to the L-shaped support frame 6, and its output shaft can drive the threaded rod 15 to rotate. A sliding rod 9 for limiting sliding is fixedly connected between the right-hand group of L-shaped support frames 6. The sliding rod 9 is symmetrical to the threaded rod 15. A sliding block 13 for movement is threadedly connected to the surface of the threaded rod 15, and a sliding limiter is slidably connected to the surface of the sliding rod 9. The two sliders 13 have a first support frame 3 fixedly connected to their upper surfaces for support. A brush is provided on the side of the first support frame 3 near the first support plate 7. The brush is long enough not to affect the operation of the equipment. There are two symmetrical dust collection grooves 10 slidably connected inside the equipment body 1. There are two symmetrical trapezoidal blocks 11 fixedly connected to the surface of the equipment body 1. The upper side of the trapezoidal blocks 11 is an inclined surface to facilitate dust to slide into the inside of the collection grooves 10. When it is necessary to clean the surface of the first support plate 7, the operator starts the first motor 5. The first motor 5 drives the threaded rod 15 to rotate, which further controls the movement of the sliders 13. At the same time, the sliding rod 9 can limit the movement of the first support frame 3.

[0035] The first support plate 7 has a support groove 2 inside for support and limiting. The front and rear sides of the support groove 2 are connected to the outside. The inner walls of the support groove 2 are rotatably connected to bidirectional threaded rods 4 for transmitting rotation. One end of the bidirectional threaded rod 4 extends to the outside of the first support plate 7 and is equipped with a turning device to facilitate manual control of the rotation of the bidirectional threaded rod 4 by the operator. The surface of the bidirectional threaded rod 4 is threadedly connected to two symmetrical second support frames 8 for support. Both sides of the second support frames 8 extend out of the outside of the first support plate 7. The surface of the second support frames 8 is slidably connected to the inner wall of the support groove 2. The upper surface of the second support frames 8 is fixedly connected to... A U-shaped support frame 17 for clamping is provided. The inner surface of the U-shaped support frame 17 is slidably connected to the surface of the first support plate 7. Clamping mechanisms are provided on the adjacent surfaces of the two U-shaped support frames 17 to facilitate clamping of the brake pads. When it is necessary to clamp the brake pads, the operator places the brake pads on the upper surface of the first support plate 7, and then manually turns the turning device at one end of the double-threaded rod 4 to drive the double-threaded rod 4 to rotate, further controlling the two second support frames 8 to move towards the adjacent side, further controlling the two U-shaped support frames 17 to move towards the middle, and further controlling the clamping device to clamp the brake pads.

[0036] The device body 1 has a T-shaped support column 12 for support inside. A support disk 14 for support is fixedly connected to the upper surface of the T-shaped support column 12. A second motor 22 for transmission is installed inside the T-shaped support column 12. The output shaft of the second motor 22 passes through the support disk 14 and is fixedly connected to the lower surface of the first support plate 7. The lower surface of the first support plate 7 is slidably connected to the upper surface of the U-shaped support frame 17. A first support block 16 for supporting rotation is fixedly connected to the lower surface of the T-shaped support column 12. A U-shaped support block 18 for supporting rotation is fixedly connected inside the device body 1. A third motor 25 for transmission is fixedly connected to one side surface of the U-shaped support block 18. The output shaft of the third motor 25 passes through the U-shaped support block 18 and is fixedly connected to a transmission shaft 24 for support. The side of the transmission shaft 24 away from the third motor 25 is rotatably connected inside the U-shaped support block 18. A second support plate 19 for support is fixedly connected to the surface of the transmission shaft 24.

[0037] The two sides of the second support plate 19 are rotatably connected to two symmetrical first support rods 20 for support. The two first support rods 20 are rotatably connected to the two sides of the first support block 16. The lower surface of the T-shaped support column 12 is fixedly connected to a second support block 23 for support rotation. The two sides of the second support block 23 are rotatably connected to two second support rods 21 for support. The lower surfaces of the two second support rods 21 are rotatably connected to the interior of the equipment body 1. When the angle of the first support plate 7 needs to be adjusted for better grinding and polishing, the third motor 25 drives the transmission shaft 24 to rotate, which in turn drives the second support plate 19 to rotate, further controlling the rotation of the two first support rods 20, and further controlling the first support block 16 to push one end of the T-shaped support column 12 upward. At the same time, the second support rods 21 limit the rotation of the other side of the T-shaped support column 12 through the rotatably connected second support block 23, thereby realizing the offset of the angle of the T-shaped support column 12.

[0038] Related to the first motor 5 are also the wiring, controller and other structures, which are existing structures and will not be described in detail here.

[0039] The implementation principle of the automatic grinding and polishing device for brake pads in this embodiment is as follows: When the surface of the first support plate 7 needs to be cleaned, the operator starts the first motor 5 through the controller. The first motor 5 drives the threaded rod 15 to rotate, further controlling the movement of the slider 13. At the same time, the slide rod 9 can limit the movement of the first support frame 3, further controlling the movement of the first support frame 3. The brush further controls the cleaning of the surface of the first support plate 7. The cleaned dust falls into the collection tank 10 or falls into the collection tank 10 through the inclined surface on the upper side of the trapezoidal stop 11, thus collecting the dust. When the brake pad needs to be clamped, the operator places the brake pad on the upper surface of the first support plate 7, and then manually turns the turning device at one end of the bidirectional threaded rod 4, driving the bidirectional threaded rod 4 to rotate. This further controls the two second support frames 8 to move towards each other, further controls the two U-shaped support frames 17 on both sides to move towards the middle, and further controls the clamping device to clamp the brake pad. When clamping is required, and the angle of the first support plate 7 needs to be adjusted for better grinding and polishing, the operator starts the third motor 25. The third motor 25 drives the transmission shaft 24 to rotate, which in turn drives the second support plate 19 to rotate, further controlling the rotation of the two first support rods 20. This further controls the first support block 16 to push one end of the T-shaped support column 12 upwards. At the same time, the second support rod 21 limits the rotation of the other side of the T-shaped support column 12 through the rotating second support block 23, thereby achieving the offset of the angle of the T-shaped support column 12. This is further achieved by adjusting the angle of the first support plate 7 through the support disc 14, facilitating better grinding and polishing. At the same time, the tilted angle also makes it easier to clean dust. When the brake pads on the first support plate 7 need to be fully ground, the operator starts the second motor 22. The second motor 22 drives the support disc 14 to rotate, which in turn drives the first support plate 7 to rotate. Through rotation, the brake pads are ground more thoroughly, and the function is more comprehensive.

Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
