Description

Technical Field

[0001] The invention belongs to the technical field of friction plate production and relates to a device for grinding the outer arc surface of a friction plate. Background Art

[0002] Friction pads are also called brake pads or brake leathers. In the car's braking system, brake pads are the most critical safety parts. The quality of all braking effects is determined by the brake pads, so good brake pads are the protectors of people and cars.

[0003] Braking primarily works through friction, utilizing the friction between the brake pads and brake discs (drums), and between the tires and the road, to convert the vehicle's kinetic energy into frictional heat, ultimately stopping the vehicle. A well-functioning braking system must provide stable, sufficient, and controllable braking force, while also ensuring excellent hydraulic transmission and heat dissipation. This ensures that the force applied by the driver through the brake pedal is effectively transmitted to the master cylinder and each slave cylinder, and prevents hydraulic failure and brake fade caused by excessive heat. During the friction pad production process, after the friction pad blank is produced and drilling and other processes are completed, the inner and outer curved surfaces of the friction pad are polished to achieve the desired thickness.

Moving the flexible positioning members 46 can make the two flexible positioning members 46 be located inside or outside the two stable grooves 45 respectively.

[0076] A flexible operating cylinder 47 is provided at the end of the flexible positioning member with a larger diameter, and an operating ring 48 is provided on the outer wall of the end of the flexible operating cylinder 47 away from the flexible positioning member 46. The inner wall of the operating ring 48 and the inner wall of the flexible operating cylinder 47 are both movably fitted to the linkage member 44.

[0077] The present invention provides a device for grinding the outer arc surface of a friction plate. When grinding the outer arc surface of the friction plate, the inner arc surface of the friction plate needs to be fitted on the feed plate 3 first, and then the friction plate can be conveyed forward under the driving action of the protrusion 4; at the same time, the power rod 6 drives the grinding plate 7 and the grinding body 8 to rotate, and grinds the outer arc surface of the friction plate between the feed plate 3 and the grinding body 8, which is simple and convenient. According to the actual production situation, when different thicknesses need to be ground in different places of the friction plate, the movable support platform 5 can also move closer to or farther away from the feed plate 3 to grind different thicknesses at different positions of the friction plate; at the same time, during actual grinding, the rotation speed of the feed plate 3 is relatively slow, but the rotation speed of the grinding plate 7 is very fast, so that the outer arc surface of the friction plate can be quickly ground.

[0078] During actual grinding, first the first motor 10 drives the feeding rod 11 to rotate, and the feeding rod 11 drives the feeding tray 3 to rotate; at the same time, a plurality of friction plates are stacked vertically on the loading rack 25; the loading cylinder 27 (preferably a cylinder, or an electric push rod, etc.) pushes the outermost friction plate, thereby pushing the innermost friction plate to fit the outer wall of the feeding tray 3 (wherein the gap between the end of the loading rack 25 and the support ring 9 is very small, and the loading rack 25 and the support ring 9 are at the same height, so the friction plate can be easily transitioned to the support ring 9; at the same time, the "set distance", "set gap" or similar descriptions in this application all indicate that the two structures are in a non-contact state, and the specific gap size can be selected according to actual conditions), then the feeding tray 3 rotates, and drives the friction plate to move downstream through the protrusion 4, and moves to the grinding body 8 at the edge of the grinding disc 7 for grinding;

[0079] During the movement of the friction plate, only the friction plate attached to the feed tray 3 on the downstream side can pass between the limit plate 26 and the feed tray 3, and the other friction plates are limited by the limit plate 26 and cannot be driven under the equipment; secondly, before the friction plate is polished, the friction plate driven by the protrusion 4 is still limited by the friction plate in the original position and will not fall; at the same time, the support ring 9 at the bottom can also improve the position stability between the friction plate and the feed tray 3, and because the friction plate is arc-shaped, it can be more stably connected to the feed tray 3;

[0080] When the grinding is completed, the friction plate continues to be driven and driven by the feed tray 3 and the support ring 9 (the thickness of the support ring 9 is smaller than that of the friction plate and will not interact with the grinding body 8). When it moves to the blanking piece 28, the blanking piece 28 acts on the inner side or edge of the friction plate, thereby pushing the friction plate down from the feed tray 3 (the edge of the friction plate is inclined, and the blanking piece 28 acts on the position near the top of the friction plate, so it can drive the friction plate to fall from the feed tray 3); the friction plate falls onto the conveyor belt 30 under the action of gravity; at the same time, the fifth motor drives the conveyor frame 29 and the conveyor belt 30 to rotate, and transports the friction plate downstream until the friction plate slides from the conveyor belt 30 to the blanking roller 32 on the blanking frame 31, and then slides down under the action of gravity, and the workers carry out subsequent processing.

[0081] The present application is not only capable of grinding friction plates of different thicknesses, but also capable of grinding different thicknesses at different positions of the same friction plate. Specifically, during the grinding process, the second motor 14 is controlled by the controller to rotate forward or reverse, thereby driving the movable support platform 5 close to or away from the first support platform 1, and at the same time adjusting the distance between the grinding body 8 and the feed tray 3, so that the processing effect is better and friction plates with special requirements can be processed.

[0082] The first screw rod 15 is rotatably connected through the two first linkage blocks, so its position and structural strength are relatively large, and the second motor 14 only needs to control the first screw rod 15 to rotate; the cross-sections of the two first support rails 12 are both Ω-shaped, and the first matching rail 13 is buckled on the first support rail 12, thereby ensuring that the movable support platform 5 can only move along the length direction of the first support rail 12; the shape of the first support rail 12 is the same as that of the second support rail 34, and the shape of the first matching rail 13 is also the same as that of the second matching rail 35; the shape of the first support seat 16 is also the same as that of the second support seat 36, the shape of the first linkage block is the same as that of the second linkage block, and the shape of the first screw rod 15 is the same as that of the second screw rod 37.

[0083] In the actual production process, it is also necessary to grind friction plates of different widths, and at this time, the height of the first support platform 1 needs to be adjusted; when adjusting, only the fourth motor 23 needs to drive the lifting screw 22 to rotate; when the lifting screw 22 rotates, it can drive the first support platform 1 to rise or fall, and at the same time drive the height change of the feed tray 3, wherein the four stabilizing rods 24 and stabilizing holes 43 are passed between the first support platform 1 and the third support platform 21, so that the first support platform 1 can be stably raised and lowered; at the same time, the first motor 10 is fixedly connected to the bottom of the first support platform 1, so even if the height of the first support platform 1 changes, the first motor 10 can function normally.

[0084] In actual production, the grinding body 8 is long and the length direction of the grinding body 8 passes through the straight line where the axis of the grinding disc 7 is located; therefore, the wear rate of the grinding body 8 at different positions is different. In actual use, the position of the entire grinding disc 7 can be adjusted so that the grinding bodies 8 at different positions can be utilized, preventing the grinding body 8 from being discarded after only partially being used.

[0085] When adjusting the position of the entire grinding disc 7, the worker first drives the flexible operating cylinder 47 and the flexible positioning member 46 (both made of flexible materials, preferably silicone or rubber, etc.) through the operating ring 48 (preferably made of hard material) to move, and the flexible positioning member 46 moves out of the two stabilizing grooves 45;

[0086] The adjusting hand wheel 38 is then manually rotated, which drives the second screw rod 37 to rotate, thereby adjusting the position of the second support platform 2 and allowing the second support platform 2 to move stably along the length direction of the second support rail 34. When the second screw rod 37 rotates, it also drives the driving gear 42 to rotate, and the driving gear 42 drives the stabilizing screw rod 40 to rotate, thereby generating a relative displacement between the stabilizing screw rod 40 and the support frame 39. During this process, the second support platform 2 and the stabilizing screw rod 40 move in opposite directions.

[0087] The passive tooth 41 is in the shape of a long column. Therefore, during use, even if relative displacement occurs between the passive tooth 41 and the active tooth 42 , the active tooth 42 can still normally drive the passive tooth 41 to rotate.

[0088] When the position of the grinding body 8 reaches an appropriate level, the adjusting hand wheel 38 is kept stationary, and then the flexible operating cylinder 47 and the flexible positioning member 46 are slid through the operating ring 48, and the two flexible positioning members 46 are respectively engaged in the two stable grooves 45. At this time, the adjustment of the position of the grinding body 8 is completed, so that the grinding bodies 8 in different positions can be utilized, thereby increasing their service life and reducing their use costs.

[0089] During the processing, since the movable support platform 5 has a large mass and needs to move frequently, it is necessary to fully stabilize the position of the second support platform 2 so that the movable support platform 5 can stably perform processing; when the adjustment of the second screw rod 37 is completed, if the second support platform 2 has relative sliding with the fourth support platform 33, then it is necessary for the second screw rod 37 and the second linkage block to rotate relative to each other, and for the linkage member 44 and the adjustment screw rod to slide relative to each other;

[0090] However, when the second screw rod 37 is rotating and the linkage member 44 is moving relative to the stabilizing screw rod 40, the linkage member 44 and the stabilizing screw rod 40 are moving in the same direction, so the relative movement distance between the two will be magnified. At the same time, the two flexible positioning members 46 are respectively engaged in the two stabilizing grooves 45. In this way, when the linkage member 44 and the stabilizing screw rod 40 move relative to each other, the flexible positioning members 46 can prevent the two from sliding relative to each other by self-locking. And since there are two flexible positioning members 46, no matter whether the second support platform 2 is facing one direction or the other, the two flexible positioning members 46 can play a self-locking role for the linkage member 44 and the stabilizing screw rod 40.

[0091] If the position of the stabilizing screw 40 is fixed (without the active teeth 42 and the passive teeth 41), then the two flexible positioning members 46 can also play a positioning role for the linkage member 44. However, in this embodiment, the linkage member 44 and the stabilizing screw 40 can increase their movement speed and relative movement distance through the active teeth 42 and the passive teeth 41, thereby achieving a better locking effect.

[0092] The flexible positioning member 46 and the flexible operating cylinder 47 are both flexible, which can increase the friction between them and the linkage member 44. At the same time, the operating ring 48 can facilitate operation and reduce the difficulty of operation.

[0093] When the power rod 6 rotates, the third motor 17 drives the active disc 18 to rotate, and the active disc 18 drives the passive disc 19 to rotate through the transmission member 20 (belt), and finally drives the power rod 6 and the grinding disc 7 to rotate.

[0094] In another embodiment, the position of the stabilizing screw 40 is fixed, and there are no active teeth 42 and passive teeth 41 . In this case, the linkage member 44 is locked by two flexible positioning members 46 .

[0095] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.

[0096] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
