Description

Technical Field

[0001] This utility model relates to the field of brake pad processing technology, specifically an integrated equipment for grinding and polishing automotive brake pads. Background Technology

[0002] Brake pad grinding and polishing is a repair operation that uses specialized tools to treat and correct the surface and shape of brake pads (brake friction blocks) when there are abnormal wear, hardening, or uneven wear on the surface or edges. The core purpose is to restore the normal friction performance of the brake pads, eliminate abnormal braking noise, and extend the service life of the brake pads in conjunction with the brake discs. It falls under the category of brake pad maintenance rather than replacement.

[0003] Chinese Patent No. 202023088370.5 discloses a grinding device for processing automotive resistance devices, including a housing, a cover plate movably connected to one side of the housing, a handle fixedly connected to one side of the cover plate, a base plate fixedly connected to the inner bottom wall of the housing, a roller movably connected to the front of the housing, and a support plate movably connected to the inner wall of the housing.

[0004] When this utility model is used, it performs a one-time grinding process, which puts a lot of pressure on the grinding mechanism. This not only leads to low grinding efficiency, but also affects the grinding efficiency of the brake pads. Utility Model Content

[0005] The purpose of this invention is to provide an integrated grinding and polishing equipment for automotive brake pads to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated grinding and polishing equipment for automotive brake pads, comprising a grinding and polishing device; the grinding and polishing device comprises a base, a rotating table, and a protective frame; a large bearing is installed at the bottom of the rotating table, the large bearing is installed on the upper side of the base; a power mechanism is installed between the bottom of the rotating table and the base; a support mechanism is installed between the rotating table and the base; multiple placement platforms are evenly installed on the upper part of the rotating table; a clamping mechanism is installed on the upper part of the placement platform; the protective frame is installed on the upper part of the base and covers the upper part of the rotating table; dust extraction mechanisms are installed at both ends of the outer side of the protective frame; lifting mechanisms are installed on both sides and the middle of the upper part of the protective frame; and multiple grinding and polishing mechanisms are installed at the bottom of the lifting mechanisms.

[0007] Preferably, the dust extraction mechanism consists of a dust extraction hood and a fan. The dust extraction hood is installed on both sides of the protective frame, a pipe is installed at the rear end of the dust extraction hood, and a fan is installed inside the dust extraction hood.

[0008] Preferably, the support mechanism consists of a support column and a ball bearing. The support column is mounted on the upper side of the base, and the ball bearing is rotatably mounted on the upper side of the support column. The upper end of the ball bearing is slidably connected to the rotary table.

[0009] Preferably, the power mechanism consists of a power motor, a drive gear, and an internal gear. The internal gear is installed inside the bottom of the rotary table, and the drive gear and the internal gear are meshed together. The bottom of the drive gear is installed on the upper side of the power motor, and the power motor is installed on one side inside the base.

[0010] Preferably, the clamping mechanism consists of a clamping plate, a multi-segment bidirectional lead screw, a lead screw nut, and a contour clamping plate. The multi-segment bidirectional lead screw is rotatably installed in the middle of the placement platform. One end of the multi-segment bidirectional lead screw extends out of the outer side of the placement platform and is provided with an insertion hole. The lead screw nut is rotatably installed on both sides of the upper end of the multi-segment bidirectional lead screw. The lead screw nut is installed at the bottom end of the clamping plate, and the upper end of the clamping plate extends out of the upper side of the placement platform.

[0011] Preferably, the lifting mechanism consists of a telescopic rod and a mounting frame. The telescopic rod is installed at the middle and both sides of the upper end of the protective frame, and the mounting frame is installed at the bottom end of the telescopic rod inside the protective frame.

[0012] Preferably, the grinding and polishing mechanism consists of a grinding motor and a grinding plate. The grinding motor is mounted on the upper side of the mounting frame, and the grinding plate is mounted on the bottom end of the grinding motor. The grinding coefficient of the grinding plate increases sequentially along the rotation direction of the rotary table.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Multiple grinding and polishing mechanisms sequentially grind and polish the brake pads conveyed on the rotary table in order of increasing grinding coefficient. Through gradual and fine grinding, the grinding quality of the car brake pads is effectively improved.

[0015] 2. When the pry bar is inserted into the insertion hole and the multi-segment double-acting screw is rotated, because the threads at both ends of the multi-segment double-acting screw are in opposite directions, the screw nuts installed on both sides of the upper end of the multi-segment double-acting screw will move in opposite or opposite directions along the screw. The screw nuts drive the connected clamping plates to move synchronously, causing the two clamping plates to move closer or further apart, thereby clamping or releasing the car brake pads placed on the placement table. The conforming clamping plates can better conform to the shape of the brake pads, ensuring a more secure and reliable clamping.

[0016] 3. When the height of the grinding and polishing mechanism needs to be adjusted, the telescopic rod drives the mounting bracket to move up and down through the telescopic action, thereby causing the grinding and polishing mechanism mounted on the mounting bracket to rise and fall accordingly, so as to adapt to the grinding needs of automotive brake pads of different thicknesses and ensure that the grinding and polishing mechanism and the brake pad maintain appropriate grinding pressure and distance.

[0017] 4. When the grinding motor starts, it drives the grinding plate to rotate at high speed. As the grinding coefficient of the grinding plate increases sequentially along the rotation direction of the rotary table, when the rotary table drives the car brake pads through each grinding and polishing mechanism in sequence, the grinding plate with the smaller grinding coefficient first performs preliminary grinding on the brake pads to remove the rougher parts of the surface. Then, the grinding plates with the gradually increasing grinding coefficient perform fine grinding and polishing, making the surface of the brake pads gradually become smooth and flat, and finally achieving the ideal grinding and polishing effect, realizing the integrated processing of grinding and polishing of car brake pads.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the present invention, an integrated grinding and polishing equipment for automotive brake pads includes a grinding and polishing device 1. The grinding and polishing device 1 comprises a base 2, a rotating table 3, and a protective frame 27. A large bearing 9 is installed at the bottom of the rotating table 3, and the large bearing 9 is installed on the upper side of the base 2. A power mechanism 7 is installed between the bottom of the rotating table 3 and the base 2. A support mechanism 4 is installed between the rotating table 3 and the base 2. Multiple placement platforms 12 are evenly installed on the upper end of the rotating table 3. A clamping mechanism 22 is installed on the upper end of the placement platform 12. The protective frame 27 is installed on the upper end of the base 2 and covers the upper side of the rotating table 3. Dust extraction mechanisms 19 are installed at both ends of the outer side of the protective frame 27. Lifting mechanisms 17 are installed on both sides and the middle position of the upper end of the protective frame 27. Multiple grinding and polishing mechanisms 16 are installed at the bottom end of the lifting mechanism 17.

[0026] The dust extraction mechanism 19 consists of a dust extraction hood 20 and a fan 21. The dust extraction hood 20 is installed on both sides of the protective frame 27. A pipe is installed at the rear end of the dust extraction hood 20. The fan 21 is installed inside the dust extraction hood 20. When the device performs grinding and polishing operations, a large amount of dust will be generated. The dust extraction hood 20 installed on the side of the protective frame 27 is aligned with the grinding area. After the fan 21 inside the dust extraction hood 20 is started, it generates negative pressure, which sucks in the dust generated during grinding through the dust extraction hood 20 and then transports it to the designated dust collection position through the pipe at the rear end. This achieves effective collection and treatment of dust during the grinding process and reduces the impact of dust on the working environment and operators.

[0027] The support mechanism 4 consists of a support column 10 and a ball bearing 11. The support column 10 is mounted on the upper side of the base 2, and the ball bearing 11 is rolled on the upper side of the support column 10. The upper end of the ball bearing 11 is slidably connected to the rotating platform 3. When the rotating platform 3 is driven by the power mechanism 7 to rotate, the bottom end of the rotating platform 3 contacts the upper end of the ball bearing 11 and slides relative to it. The ball bearing 11 rolls accordingly, converting the sliding friction between the rotating platform 3 and the base 2 into rolling friction. This reduces the friction force when the rotating platform 3 rotates, making the rotating platform 3 run more smoothly and stably. It also reduces the load on the power mechanism 7 and extends the service life of the equipment.

[0028] The power mechanism 7 consists of a power motor 6, a drive gear 5, and an internal gear 8. The internal gear 8 is installed inside the bottom of the rotary table 3. The drive gear 5 and the internal gear 8 are meshed together. The bottom of the drive gear 5 is installed on the upper side of the power motor 6. The power motor 6 is installed inside the base 2 on one side. When the power motor 6 starts, its output shaft drives the drive gear 5 at the upper end to rotate. Since the drive gear 5 and the internal gear 8 installed inside the bottom of the rotary table 3 mesh with each other, the rotation of the drive gear 5 will drive the internal gear 8 to rotate, thereby driving the entire rotary table 3 to rotate around the central axis of the large bearing 9, realizing the smooth rotation of the rotary table 3, and providing power for the automotive brake pads on the placement platform 12 to be sequentially transported to the positions of each grinding and polishing mechanism 16.

[0029] The clamping mechanism 22 consists of a clamping plate 23, a multi-segment bidirectional lead screw 25, a lead screw nut 26, and a contour clamping plate. The multi-segment bidirectional lead screw 25 is rotatably installed inside the middle of the placement platform 12. One end of the multi-segment bidirectional lead screw 25 extends out of the outer side of the placement platform 12 and is provided with an insertion hole 24. The lead screw nut 26 is rotatably installed on both sides of the upper end of the multi-segment bidirectional lead screw 25. The lead screw nut 26 is installed at the bottom end of the clamping plate 23, and the upper end of the clamping plate 23 extends out of the upper side of the placement platform 12. When the pry bar is inserted into the insertion hole 24 and the multi-segment bidirectional lead screw 25 is rotated, since the thread directions at both ends of the multi-segment bidirectional lead screw 25 are opposite, the lead screw nuts 26 installed on both sides of the upper end of the multi-segment bidirectional lead screw 25 will move in opposite or opposite directions along the lead screw. The lead screw nuts 26 drive the clamping plate 23 connected to it to move synchronously, so that the two clamping plates 23 move closer or further apart, thereby clamping or releasing the car brake pads placed on the placement platform 12. The contour clamping plate can better fit the shape of the brake pads, ensuring a more secure and reliable clamping.

[0030] The lifting mechanism 17 consists of a telescopic rod 18 and a mounting frame 15. The telescopic rod 18 is installed at the middle and both sides of the upper end of the protective frame 27. The mounting frame 15 is installed at the bottom of the telescopic rod 18 inside the protective frame 27. When it is necessary to adjust the height of the grinding and polishing mechanism 16, the telescopic rod 18 drives the mounting frame 15 to move up and down through the telescopic action, thereby causing the grinding and polishing mechanism 16 installed on the mounting frame 15 to rise and fall accordingly, so as to adapt to the grinding needs of automotive brake pads of different thicknesses and ensure that the grinding and polishing mechanism 16 and the brake pad maintain a suitable grinding pressure and distance.

[0031] The grinding and polishing mechanism 16 consists of a grinding motor 14 and a grinding plate 13. The grinding motor 14 is mounted on the upper side of the mounting bracket 15, and the grinding plate 13 is mounted on the bottom end of the grinding motor 14. The grinding coefficient of the grinding plate 13 increases sequentially along the rotation direction of the rotary table 3. When the grinding motor 14 starts, it drives the grinding plate 13 to rotate at high speed. Since the grinding coefficient of the grinding plate 13 increases sequentially along the rotation direction of the rotary table 3, when the rotary table 3 drives the car brake pads to pass through each grinding and polishing mechanism 16 in sequence, the brake pads are first initially ground by the grinding plate 13 with a smaller grinding coefficient to remove the rougher parts of the surface. Then, the brake pads are finely ground and polished by the grinding plates 13 with gradually increasing grinding coefficients, so that the surface of the brake pads gradually becomes smooth and flat, and finally the ideal grinding and polishing effect is achieved, realizing the integrated processing of grinding and polishing of car brake pads.

[0032] The working principle and usage process of this utility model are as follows: The base 2 serves as the basic support structure for the entire device, providing a stable mounting platform for each component. The rotary table 3 is mounted on the upper side of the base 2 via a large bearing 9 at the bottom, allowing the rotary table 3 to rotate flexibly around the base 2. The power mechanism 7 provides driving force for the rotation of the rotary table 3, while the support mechanism 4 provides auxiliary support during the rotation of the rotary table 3, ensuring its smooth operation. Multiple placement platforms 12 at the upper end of the rotary table 3 are used to support the automotive brake pads to be processed. The clamping mechanism 22 on each placement platform 12 can firmly fix the brake pads to prevent over-grinding. If displacement occurs during the process, the protective frame 27 covers the rotary table 3, which not only provides safety protection but also provides a mounting carrier for other components. The dust extraction mechanism 19 on the outside of the protective frame 27 can promptly remove the dust generated during grinding, keeping the working environment clean. The lifting mechanism 17 at the top of the protective frame 27 can drive the grinding and polishing mechanism 16 to move up and down to adapt to the grinding needs of brake pads of different thicknesses. Multiple grinding and polishing mechanisms 16 perform grinding and polishing operations on the brake pads conveyed from the rotary table 3 in sequence according to the increasing grinding coefficient. Through gradual and fine grinding, the grinding quality of automotive brake pads is effectively improved.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
