Abstract
Description
A grinding device for easy fixing of brake discs Technical Field
[0001] This utility model relates to the field of brake disc processing technology, and in particular to a grinding device for brake discs that is easy to fix. Background Technology
[0002] During vehicle use, frequent braking can cause wear on the brake disc surface, resulting in scratches, grooves, hardened layers, or accumulated impurities. This leads to uneven contact between the brake pads and the brake disc, reducing the coefficient of friction and affecting braking performance, increasing braking distance, and potentially causing vibration and abnormal noise. Polishing can eliminate surface unevenness, remove hardened layers and impurities, restore good friction performance, allow the brake pads to better fit the brake disc, making the braking process smoother and more responsive. It also helps extend the service life of the brake discs and brake pads, reducing vehicle maintenance costs.
[0003] Chinese Patent Publication No. CN210649910U discloses a grinding device for automotive brake discs, comprising: a base plate; a worktable, the bottom of which is fixed to the top of the base plate, and the worktable having an internal movable groove; a fixed plate, the top and bottom of which are respectively fixed to the top and bottom of the inner wall of the movable groove, a motor fixedly connected to one side of the fixed plate, and a rotating shaft fixedly connected to the output shaft of the motor, one end of which passes through the worktable and extends to the top of the worktable. This utility model relates to the field of brake disc processing technology. This grinding device for automotive brake discs allows adjustment of the distance between the grinding block and the brake disc by moving the grinding block left and right, facilitating better grinding. The outer surface grinding is completed by the rotation of the brake disc. It is not only simple to operate and convenient to use, but also effectively improves the stability during grinding by using the rotation of the brake disc, indirectly improving the grinding effect.
[0004] While existing technologies can effectively improve stability during the grinding process and thus indirectly optimize the grinding effect, the brake disc fixing process requires workers to manually rotate the lead screw to complete the fixing operation. This manual fixing method results in low work efficiency. Summary of the Invention

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] Referring to Figures 1-5, a grinding device for easy fixing of brake discs includes an L-shaped base 1. A rotating housing 2 is rotatably connected inside the L-shaped base 1. A fixing component 3 is disposed inside the rotating housing 2. The fixing component 3 includes a limiting groove 301, a limiting slider 302, a clamping block 303, a transmission slider 304, a locking block 305, an electric push rod 306, a trapezoidal block 307, a transmission disc 308, and a rotary motor 309. The limiting groove 301 is arranged in a circular array at the front end of the rotating housing 2, and the limiting slider 302 is slidably connected to... Inside the limiting slide groove 301, the clamping block 303 is fixedly connected to the front end of the limiting slider 302, the transmission slider 304 is fixedly connected to the rear end of the limiting slider 302, the locking block 305 is fixedly connected to the opposite side of the limiting sliders 302, the electric push rod 306 is fixedly installed in the rear part of the rotating housing 2, the trapezoidal block 307 is fixedly installed in the telescopic end of the electric push rod 306, the transmission disc 308 is fixedly connected to the rear end of the rotating housing 2 and passes through the back of the L-shaped base 1, and the rotary motor 309 is fixedly installed in the L-shaped base 1.
[0025] The limiting slider 302 is adapted to the limiting slide groove 301, the trapezoidal block 307 and the transmission slider 304 are movably engaged by the locking block 305, and the transmission end of the rotary motor 309 is connected to the transmission disc 308 through the transmission belt.
[0026] The clamping block 303 has an arc-shaped side, which protects the brake disc during its contact with the inner ring of the brake disc. The trapezoidal block 307 has grooves on its four sides to accommodate the locking block 305. The fixing component 3 is set up so that by activating the electric push rod 306, the telescopic end of the electric push rod 306 drives the trapezoidal block 307 to move. During the movement, the trapezoidal block 307 continuously squeezes the transmission slider 304 and the locking block 305 through its side, so that the transmission slider 304 drives the limiting slider 302 to move inside the limiting groove 301. When the limiting slider 302 moves, it pushes the clamping block 303, thereby supporting and fixing the inside of the brake disc. Then, the rotary motor 309 is activated, so that the transmission end of the rotary motor 309 drives the transmission disc 308 and the rotating housing 2 to rotate through the belt, thereby further driving the brake disc to rotate. This utility model uses the movement of trapezoidal block 307 to push the surrounding transmission slider 304, thereby causing the limiting slider 302 to drive the clamping block 303 to unfold and support and fix the brake disc, effectively improving the safety and convenience of brake disc fixing and increasing the grinding efficiency of workers.
[0027] Furthermore, an adjustment component 4 is provided on the right side of the L-shaped base 1. The adjustment component 4 includes a second limiting slide groove 401, a threaded rod 402, a stepper motor 403, an L-shaped support rod 404, a second electric push rod 405, and a connecting block 406. The second limiting slide groove 401 is opened on the right side of the L-shaped base 1, and the threaded rod 402 is rotatably connected inside the second limiting slide groove 401.
[0028] Stepper motor 403 is fixedly installed at the front of the lower part of L-shaped base 1 and is connected to threaded rod 402 for transmission. L-shaped support rod 404 is slidably connected inside the limiting slide groove 401 and is threadedly connected to threaded rod 402. Electric push rod 405 is fixedly installed on the top of L-shaped support rod 404. Connecting block 406 is fixedly installed on the telescopic end of electric push rod 405. Grinding block 5 is fixedly installed on the side of connecting block 406.
[0029] The grinding block 5 is fixedly installed on the side of the connecting block 406 by bolts. The bottom of the L-shaped support rod 404 is adapted to the limiting slide groove 401. The adjustment component 4 is set up so that the stepper motor 403 is started, and the transmission end of the stepper motor 403 drives the threaded rod 402 to rotate. During the rotation of the threaded rod 402, the L-shaped support rod 404 can be moved due to its adaptation to the limiting slide groove 401 and its threaded connection with the threaded rod 402. The position of the L-shaped support rod 404 is adjusted. Then, the electric push rod 405 is started so that the telescopic end of the electric push rod 405 drives the grinding block 5 to extend and contact the brake disc. The grinding operation is achieved by rotating the brake disc. In this invention, a stepper motor 403 drives a threaded rod 402 to rotate, which in turn moves an L-shaped support rod 404, thereby facilitating the adjustment of the position of the grinding block 5. Furthermore, an electric push rod 405 drives the grinding block 5 to move, thus facilitating the grinding of the side of the brake disc by the grinding block 5.
[0030] Furthermore, a suction pipe 6 is fixedly connected to the upper part of the lower part of the L-shaped base 1, and a dust collection head 7 is fixedly connected to the top of the suction pipe 6. A barrier strip 8 is fixedly installed inside the dust collection head 7.
[0031] The suction pipe 6 is equipped with a fan to extract the dust generated during the grinding process. The dust collection head 7 expands the dust collection range of the suction pipe 6 to prevent dust from scattering. The installation of the barrier strip 8 can prevent large objects from falling into the suction pipe 6 and causing blockage inside the suction pipe 6.
[0032] Furthermore, the front end of the lower part of the L-shaped base 1 is provided with a ash discharge port 9, which is connected to the ash suction pipe 6. The bottom of the L-shaped base 1 is fixedly connected with anti-slip pads 10 in a rectangular array.
[0033] The ash discharge port 9 is used to discharge the dust inside the ash suction pipe 6. Workers can collect the discharged dust by placing a collection can at the ash discharge port 9. The installation of the anti-slip mat 10 increases the friction with the placement surface and improves the safety of placement.
[0034] In summary:
[0035] When using this utility model, first place the device in a suitable position and place the dust collection tank at the dust discharge port 9, and then the grinding operation can be carried out.
[0036] During the polishing process, the operator first hangs the brake disc on the outside of the clamping block 303. Then, the electric push rod 306 is activated, causing the telescopic end of the electric push rod 306 to move the trapezoidal block 307. As the trapezoidal block 307 moves, it continuously presses against the transmission slider 304 and the locking block 305 from the side. This causes the transmission slider 304 to move the limiting slider 302 inside the limiting groove 301. When the limiting slider 302 moves, it pushes the clamping block 303, thereby supporting and fixing the brake disc internally. Then, the rotary motor 309 is activated, causing the transmission end of the rotary motor 309 to drive the transmission disc 308 and the rotating housing 2 to rotate via a belt, thereby further rotating the brake disc.
[0037] Next, the stepper motor 403 is started, which drives the threaded rod 402 to rotate. During the rotation of the threaded rod 402, the L-shaped support rod 404 is adapted to the limit slide groove 401 and threadedly connected to the threaded rod 402, so the L-shaped support rod 404 can be moved to adjust its position. Then, the electric push rod 405 is started, which causes the telescopic end of the electric push rod 405 to extend the grinding block 5 and contact the brake disc. The grinding operation is then achieved by rotating the brake disc.
[0038] Finally, during the polishing process, the fan inside the dust suction pipe 6 is activated to extract the dust generated during polishing, and then the dust is discharged into the dust collection tank through the dust discharge port 9, which prevents the dust from scattering and improves environmental protection.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
