Description

Technical Field

[0001] The present invention relates to the technical field of disc brake pad processing equipment, and specifically relates to a disc brake pad grinding and rust removal equipment with a waste chip collection mechanism. Background Art

[0002] In the field of disc brake pad production and maintenance, grinding and rust removal equipment is used to remove rust and impurities on the surface of disc brake pads to restore their friction performance and appearance quality. The equipment realizes synchronous grinding of the upper and lower surfaces of the disc brake pads by driving the relative rotation of the grinding seat and the top ring through a motor, and performs all-round treatment on the side surface through the cooperation of the elastic sheet and the grinding pipe. At the same time, the collection tank and the pneumatically driven debris cleaning mechanism are used to ensure the high efficiency and cleanliness of the grinding process. It is applicable to the automated grinding operation of various disc brake pads and is of great significance for improving product quality and production efficiency.

[0003] Traditional disc brake pad grinding equipment has significant deficiencies. In terms of grinding efficiency, traditional equipment usually can only grind one side of the disc brake pad, requiring multiple turning operations, which is time-consuming and laborious, and it is difficult to ensure the consistency of grinding on the upper and lower surfaces. The sealing performance is poor, and there is a lack of an effective waste chip collection mechanism. Metal chips generated during the grinding process are prone to fly everywhere, not only polluting the working environment, but also possibly causing internal wear of the equipment or safety hazards to operators. In terms of structural design, traditional equipment cannot effectively grind the side surface of the disc brake pad, and often requires manual supplementary grinding, resulting in insufficient processing accuracy and extended production processes. In addition, the waste chip cleaning of traditional equipment relies on manual regular disassembly and cleaning, which is prone to affect the grinding effect due to chip accumulation, and even cause scratches on the surface of the disc brake pad or blockage of the equipment, restricting the improvement of production efficiency and product quality, and urgently needs to be improved through integrated grinding and intelligent waste chip collection technology.

[0020] First embodiment: Figures 1 to 8 As shown, the present invention provides a technical solution: a disc brake pad grinding and rust removal device with a waste chip collection mechanism, comprising a mounting plate 1, a bottom edge of the mounting plate 1 is fixedly connected with a leg 2, and further comprising: A grinding mechanism 3, which is fixedly mounted on the mounting plate 1; An auxiliary mechanism 4, the auxiliary mechanism 4 is fixedly installed inside the grinding mechanism 3; The grinding mechanism 3 includes a chassis 31, which is rotatably connected to the middle upper surface of the mounting plate 1, and a motor 32 is fixedly installed in the middle of the bottom surface of the mounting plate 1. The output shaft of the motor 32 passes through the mounting plate 1 and is fixedly connected to the middle of the bottom surface of the chassis 31.

[0021] A connecting pipe 33 is fixedly connected to the upper surface of the bottom plate 31 , a grinding seat 34 is fixedly connected to the top of the connecting pipe 33 , and a connecting ring 35 is fixedly connected to the upper edge surface of the grinding seat 34 .

[0022] The upper surface of the connecting ring 35 is movably inserted with a top ring 36. The upper surface of the middle part of the top ring 36 is rotatably connected with a mounting cover 37. The outer surface of the top of the mounting cover 37 is fixedly sleeved with a connecting frame 38. The two upper surfaces of the mounting plate 1 are symmetrically and fixedly connected with sliding rods 39. One end of the connecting frame 38 away from the mounting cover 37 is slidably sleeved on the sliding rod 39.

[0024] The upper surface of the middle part of the chassis 31 is fixedly connected with a grinding pipe 311. The grinding pipe 311 is arranged inside the connecting pipe 33. The grinding pipe 311 and the connecting pipe 33 are set on the same central axis. The top side surface of the grinding pipe 311 is fitted against the inner surface of the brake disc. The upper surface of the grinding pipe 311 and the upper surface of the top ring 36 are set on the same plane.

[0025] A polymerization groove 312 is penetrated and opened on the upper surface of the middle part of the grinding seat 34. The polymerization groove 312 communicates with the connecting pipe 33. A collecting groove 313 is opened on the upper surface of the grinding seat 34. The bottom surface of the collecting groove 313 is set as an inclined surface. The collecting groove 313 communicates with the polymerization groove 312. A cleaning groove 314 is opened on the outer surface of the top of the grinding pipe 311. A discharge groove 315 is penetrated and opened on the outer surface of the bottom of the connecting pipe 33.

[0026] The second embodiment: As Figures 1 to 8 shown, the auxiliary mechanism 4 includes an elastic sheet 41. The elastic sheet 41 is set as an arc shape. The elastic sheet 41 is fixedly connected to the inner surface of the connecting ring 35. The outer surface of the elastic sheet 41 is elastically pressed and fitted into the outer groove of the brake disc. The inner surface of the elastic sheet 41 is fixedly connected with a support bladder 42.

[0027] The inner surface of the top of the grinding pipe 311 is fixedly connected with a support ring 43. A limiting groove 44 is opened on the upper surface of the support ring 43. The upper surface of the support ring 43 is slidably connected with a first plugging plate 45 through the limiting groove 44. The two ends of the first plugging plate 45 are elastically and slidably inserted with a second plugging plate 46. The first plugging plate 45 and the second plugging plate 46 are combined into a ring shape.

[0028] The outer surface of the No. 2 plug-in plate 46 is fixedly connected with a sliding plate 47, which penetrates and slides on the top outer surface of the polishing tube 311, and the end of the sliding plate 47 away from the No. 2 plug-in plate 46 is fixedly connected with a polishing sheet 48, which is embedded in the top outer surface of the polishing tube 311. The inner surface of the No. 1 plug-in plate 45 is fixedly connected with an expansion bag 49, and the bottom of the expansion bag 49 is fixedly connected with a connecting pipe 410. The end of the connecting pipe 410 away from the expansion bag 49 penetrates the polishing tube 311, the connecting pipe 33 and the polishing seat 34 and is fixedly connected with the bottom of the support bag 42. The bottom surface of the collecting groove 313 is fixedly inlaid with a toggle plate 411, which is made of rubber material. A connecting groove 412 is opened on the inner side of the toggle plate 411, and the connecting groove 412 is connected to the internal cavity of the support bag 42.

[0029] When working, when it is necessary to grind the disc brake pads, the connecting frame 38 can be driven to move upward along the sliding rod 39. As the connecting frame 38 moves upward, the mounting cover 37 connected to it will move upward synchronously, and then move upward together with the top ring 36, opening the top of the grinding seat 34. Then, the disc brake pads to be ground are placed on the top of the grinding seat 34 and fitted into it, and then the connecting frame 38 is driven to move downward for reset. Finally, the edge of the top ring 36 is engaged and fixed with the connecting ring 35. At the same time, the fixing rod 310 inside the mounting cover 37 is inserted into the disc brake pads. Then, the motor 32 is started. As the motor 32 starts, it will drive the chassis 31 to rotate. The rotation of the chassis 31 will drive the grinding seat 34 to rotate through the connecting pipe 33, and then drive the top ring 36 to rotate through the connecting ring 35 fixedly connected to it, so that the grinding seat 34 and the top ring 36 rotate relative to the disc brake pads, thus completing the synchronous grinding of the upper and lower surfaces of the disc brake pads, greatly reducing the overall grinding time of the disc brake pads, improving the grinding efficiency. At the same time, through the fixed insertion of the top ring 36 and the connecting ring 35, the whole device is in a closed state during grinding, thus avoiding the problem that it is difficult to clean due to the flying of debris during grinding. When the grinding seat 34 rotates, the elastic piece 41 on the connecting ring 35 and the grinding pipe 311 on the chassis 31 rotate synchronously. By the contact and extrusion of the elastic piece 41 with the inner and outer side surfaces of the grinding pipe 311 and the disc brake pads, the side surfaces of the disc brake pads are ground synchronously while the upper and lower surfaces of the disc brake pads are ground, thus realizing the all-round grinding of the disc brake pads by this device, directly forming in one grinding, further reducing the grinding time and avoiding the problem of secondary grinding. When the grinding seat 34 grinds the lower surface of the disc brake pads, the debris generated by grinding will continuously enter the collection groove 313 with the relative rotation of the grinding seat 34 and the disc brake pads, and enter the polymerization groove 312 through the bottom inclined surface of the collection groove 313. Finally, the debris enters the connecting pipe 33 and is discharged and cleaned through the discharge groove 315 at the bottom of the connecting pipe 33, that is, the debris generated by grinding is cleaned synchronously when the disc brake pads are ground, avoiding the problem that the surface of the disc brake pads is scratched due to the repeated friction between the upper surface of the grinding seat 34 and the disc brake pads for a long time. When the elastic piece 41 grinds the side surface of the disc brake pads, it will be intermittently extruded continuously. Then, the inner support capsule 42 of it elastically supports the elastic piece 41 to help the elastic piece 41 reset, ensuring the extrusion force of the elastic piece 41 on the disc brake pads, thus ensuring the grinding effect. When the support capsule 42 is extruded and deformed, the air pressure inside it is conveyed to the expansion capsule 49 through the communication pipe 410, so that the expansion capsule 49 starts to expand and pushes the first plug-in board 45 and the second plug-in board 46 to expand, so as to drive the grinding piece 48 to move outward through the sliding plate 47. Finally, the grinding piece 48 firmly adheres to the inner side surface of the disc brake pads, thus realizing the extrusion force of the grinding pipe 311 on the inner side surface of the disc brake pads when the disc brake pads are ground.In this way, the grinding effect of the disc brake pad is ensured, and the problem that the grinding tube 311 cannot fit tightly with the inner surface of the disc brake pad as the use time increases is avoided, thereby greatly extending the use time of the device. When the support bag 42 is squeezed, its internal air pressure is simultaneously transmitted to the connecting groove 412, thereby increasing the air pressure in the connecting groove 412. Finally, under the action of the air pressure, the toggle plate 411 begins to expand intermittently to generate vibration, that is, the debris in the collection groove 313 is cleaned synchronously during grinding, avoiding the problem of clogging of the collection groove 313.
