Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle production, in particular to a turnover and fitting mechanism for motorcycle shoe brake pads. Background Technique

[0002] Motorcycle brake pad accessories are an important part of the motorcycle braking system and are used for braking motorcycles. They are usually made of friction materials and are used to contact and rub against the brake disc (also known as the brake rotor) of the motorcycle, thereby decelerating or stopping the movement of the motorcycle. Motorcycle brake pads are usually made of friction materials (such as organic materials, semi-metallic materials or ceramic materials), which have good friction performance and wear resistance. The brake pads are fixed in the brake caliper. When the rider steps on the brake pedal, the brake caliper will squeeze the brake pads onto the brake disc, generating frictional force, thereby decelerating or stopping the rotation of the wheel.

[0003] In traditional turnover mechanisms, usually, the air pressure or hydraulic system is manually controlled to drive the clamping structure to clamp the brake pad body and then perform turnover and fitting operations. When discharging after the fitting is completed, it is necessary to control the air pressure or hydraulic system to release the limit of the clamping structure on the brake pad body and then proceed to the next step. This method highly relies on manual operation and control, usually cannot achieve automatic clamping and automatic discharging, and requires manual control of each step, reducing the automation level. Moreover, manual operation is prone to errors, which will lead to inconsistent clamping force and position, affecting product quality and operation stability. And in the clamping structure, since the outer arc of the brake pad cannot completely match the plane of the fixed bracket, it usually results in unstable clamping, and the brake pad is prone to sliding or offset during the clamping process, affecting the accuracy and stability of the operation.

[0015] The beneficial effects of the present utility model:

[0016] 1. For this kind of motorcycle hoof brake pad flipping and fitting mechanism, through the setting of the clamping assembly, through the linkage of the flipping assembly and the clamping assembly, the automatic processes of clamping, flipping, fitting and discharging of the hoof brake pad are realized, reducing the intervention of manual operation and improving the work efficiency.

[0017] 2. The flip - fitting mechanism of the motorcycle shoe brake pad. By setting a feeding component, when the feeding component is started, under the action of the third return spring, the push plate pushes the shoe brake pad body through the feeding groove to the other end of the feeding rack. When the shoe brake pad body passes through the gantry, it is limited by the limit elastic piece at the top inside the gantry and will not fall down. One end of the limit elastic piece is inclined, so that the shoe brake pad body can smoothly slide into the area of the limit elastic piece. At this time, the clamping component performs a clamping operation to clamp the shoe brake pad body. Due to the elastic design of the limit elastic piece, when the clamping component clamps the shoe brake pad body, the limit elastic piece will automatically give way and will not hinder the clamping operation. After clamping, the shoe brake pad body is smoothly taken out, and the limit elastic piece returns to its original position to prepare for the next feeding and clamping operation.

[0027] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the following further elaborates on the present utility model in combination with specific embodiments.

[0028] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present utility model should have the ordinary meanings understood by those with ordinary skills in the field to which the present utility model belongs. The "first", "second" and similar terms used in the present utility model do not indicate any order, quantity or importance, but are only used to distinguish different components.

The terms such as "connected" or "linked" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left" and "right" are only used to represent relative position relationships, and when the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0029] Such as Figures 1 to 6As shown, the motorcycle shoe brake pad flipping and fitting mechanism includes: a flipping assembly for driving the shoe brake pad to flip and fit; a clamping assembly disposed on the flipping assembly for cooperating with the flipping assembly to clamp the shoe brake pad for fitting operation; a feeding assembly inclinedly disposed on one side of the flipping assembly, on which a plurality of shoe brake pad bodies 32 are placed, and the feeding assembly is used for conveying the shoe brake pad bodies 32. The feeding assembly includes a fixed block 29 and a feeding frame 30 inclinedly installed on the fixed block 29. One end of the feeding frame 30 corresponds to the clamping assembly. A feeding groove 31 is formed inside the feeding frame 30, and a plurality of shoe brake pad bodies 32 are placed in the feeding groove 31. A push plate 33 is slidably installed at the bottom of the feeding groove 31. One end of the push plate 33 away from the shoe brake pad body 32 is provided with a third return spring 34, and one end of the third return spring 34 is fixedly connected to one end of the inner wall of the feeding groove 31;

[0030] The shoe brake pad body 32 enters the feeding assembly through the feeding groove 31. Under the action of the third return spring 34, the push plate 33 pushes the shoe brake pad body 32 to one end of the feeding groove 31 to dock it with the clamping assembly. The clamping assembly clamps the shoe brake pad body 32, and the flipping assembly starts to drive the clamping assembly to drive the shoe brake pad body 32 to perform a flipping operation so that it fits with the material conveyed by the conveyor belt (not shown in the figure) below, such as fitting with a friction plate. The tight fit between the shoe brake pad body 32 and the friction plate can ensure sufficient friction during braking, thereby improving the braking performance of the braking system. During the flipping process, the clamping assembly ensures the stability and accuracy of the shoe brake pad body 32. After the flipping is completed, the clamping assembly releases, and the flipping and fitting operation of the shoe brake pad is completed. At this time, the push plate 33 resets under the action of the third return spring 34 and is ready to push the next shoe brake pad body 32 to one end of the feeding groove 31. By repeating the above process, continuous automatic fitting operation is achieved.

[0031] As Figure 1 , Figure 6 As shown, the flipping assembly includes a fixed table 1. A first mounting block 2 is fixedly installed in the middle of the top of the fixed table 1. A cylinder 3 and a second mounting block 4 are respectively rotatably installed on both sides of the top of the fixed table 1. The telescopic end of the cylinder 3 is rotatably connected to a first rotating plate 5. The other end of the first rotating plate 5 is rotatably connected above one side of the second mounting block 4 through a rotating shaft. The rotating shaft penetrates through the second mounting block 4, and the other end of the rotating shaft is fixedly connected to a second rotating plate 8. A second rotating rod 9 is rotatably installed on the other side of the second rotating plate 8. A rotating seat 6 is rotatably installed on the top of the first mounting block 2. A first rotating rod 7 is slidably installed on the other side of the rotating seat 6. The other end of the first rotating rod 7 is connected to one end of the second rotating rod 9. Two connecting blocks 10 are also fixedly installed on both sides of the bottom of the second rotating rod 9;

[0032] The air cylinder 3 starts, pushing the first rotating plate 5 to rotate. The first rotating plate 5 drives the second rotating plate 8 to rotate through the rotating shaft. The rotation of the second rotating plate 8 drives the second rotating rod 9 to adjust the flipping angle. The second rotating rod 9 further drives the clamping assembly to perform the flipping and fitting operations of the shoe brake pads. During the flipping process of the second rotating rod 9, the first rotating rod 7 and the rotating seat 6 connected behind it rotate synchronously, ensuring the coherence and stability of the flipping action. The cooperation of the first rotating rod 7 and the rotating seat 6 provides additional support and stability, making the flipping operation smoother, reducing errors and improving the accuracy of flipping and fitting. The first rotating rod 7 and the rotating seat 6 together constitute the support and adjustment part of the flipping mechanism, ensuring the smooth progress of the flipping action. The first rotating rod 7 is connected to the second rotating rod 9 to realize the adjustment of the flipping angle, and the rotating seat 6 provides the rotational support, making the whole flipping process stable and accurate.

[0033] As Figure 3 、 Figure 4 、 Figure 5 shown, the clamping assembly includes a positioning frame 11 fixedly installed at the bottom ends of two connecting blocks 10 and a positioning plate 12 fixedly installed below the positioning frame 11. A number of positioning bolts 13 are arranged between the positioning frame 11 and the positioning plate 12 for fixation. Two mounting platforms are arranged at equal intervals at the bottom of the positioning plate 12. The first linkage frame 15 and the second linkage frame 16 are rotatably installed on both sides of the bottom of each mounting platform. The clamping plates 17 are rotatably installed at the bottoms of the first linkage frame 15 and the second linkage frame 16. Two trigger rods 18 are vertically and movably installed through the middle of the positioning plate 12. A number of trigger rods 18 are respectively adapted to the two mounting platforms. A connecting seat 19 is fixedly sleeved in the middle of the trigger rod 18. Linkage rods 20 are rotatably installed at both ends of the connecting seat 19. The two ends of the two linkage rods 20 are respectively rotatably connected to the middle parts of the two first linkage frames 15. A first return spring 21 is also sleeved on one side of the trigger rod 18. One end of the first return spring 21 is fixedly connected to the top of the connecting seat 19, and the other end is fixedly connected to the bottom of the mounting platform. The inner side of the clamping plate 17 is arranged in an arc shape, and the inner arc shape of the clamping plate 17 is consistent with the outer side radian of the shoe brake pad body 32. Pressing blocks adapted to the top of the shoe brake pad body 32 are also arranged at the bottom ends of the two trigger rods 18;

[0034] At the bottom of the positioning frame 11, two positioning sleeves 14 corresponding to the trigger rod 18 are arranged at equal intervals. At the top end of the trigger rod 18, a positioning rod 22 is fixedly installed. At the top end of the positioning rod 22, a first positioning block 23 is fixedly installed. A second positioning block 24 is slidably sleeved in the middle of the positioning rod 22. A tension spring is also arranged at the bottom of the second positioning block 24 and sleeved on the outer surface of the positioning rod 22. Through holes 25 are opened on both sides inside the positioning sleeve 14. Moving rods 26 are slidably installed inside the through holes 25. One end of the moving rod 26 located inside the positioning sleeve 14 is fixedly connected to a self-locking block 27. The bottom surface of the self-locking block 27 is arranged as an inclined surface adapted to the first positioning block 23 and the second positioning block 24. A second return spring 28 is also sleeved on the outer surface of the moving rod 26;

[0035] When clamping, the flipping assembly drives the clamping assembly to flip upward to pick up materials. At this time, the clamping plates 17 on both sides are respectively located on both sides of the brake pad body. The initial state of the clamping plates 17 is at the maximum opening degree, so they do not contact the brake pad body at this time. When the pressing block contacts the middle part of the top of the brake pad body and continues to be pressed downward, the trigger rod 18 is pushed upward by the pressing block, driving the linkage rods 20 on both sides to move and tighten, and then driving the first linkage frames 15 at the other ends of the linkage rods 20 to approach each other. At this time, the two second linkage frames 16 and the two clamping plates 17 will be driven to approach each other synchronously. Therefore, the bottom clamping plate 17 clamps the brake pad body through the arc-shaped groove adapted to the brake pad body. While the trigger rod 18 moves upward, the positioning rod 22 at the top of the trigger rod 18 is driven to move upward. First, the first positioning block 23 at the top of the positioning rod 22 is inserted into the positioning sleeve 14. The first positioning block 23 pushes the self-locking block 27 through the wedge surface at its top end, and smoothly moves the first positioning block 23 above the self-locking block 27, thereby performing limit. At this time, the brake pad body is just clamped firmly. When it is flipped down for fitting after clamping and contacts the material to be fitted below, and the bottom brake pad body is pressed downward again to fit it, the trigger rod 18 will continue to move upward a small distance at this time, so that the second positioning block 24 also passes through the self-locking block 27. At this time, both the first positioning block 23 and the second positioning block 24 are located above the self-locking block 27. At this time, under the action of the second return spring 28, the trigger rod 18 is driven to move downward. During the downward movement, the self-locking block 27 will drive the two positioning blocks to close. At this time, the limit can be easily released through the inclined surface at the bottom of the second positioning block 24, thereby opening the clamping plate 17 and achieving the states of automatic clamping, automatic fitting and discharging.

[0036] As Figure 2 shown, a gantry 35 is arranged at one end of the feeding frame 30 close to the clamping assembly. The gantry 35 is arranged in a loop shape. Two limiting elastic pieces 36 are arranged at the inner top of the gantry 35. One end of the limiting elastic piece 36 is arranged in an inclined shape;

[0037] When the feeding component is started, under the action of the third reset spring 34, the push plate 33 pushes the shoe brake pad body 32 to the other end of the feeding rack 30 through the feeding groove 31. When the shoe brake pad body 32 passes through the gantry 35, it is limited by the limiting elastic piece 36 at the inner top of the gantry 35 and will not fall downward. One end of the limiting elastic piece 36 is arranged in an inclined shape, so that the shoe brake pad body 32 can smoothly slide into the area of the limiting elastic piece 36. At this time, the clamping component performs a clamping operation to clamp the shoe brake pad body 32. Due to the elastic design of the limiting elastic piece 36, when the clamping component clamps the shoe brake pad body 32, the limiting elastic piece 36 will automatically give way and will not hinder the clamping operation. After the clamping is completed, the shoe brake pad body 32 is smoothly taken out, and the limiting elastic piece 36 returns to its original position to prepare for the next feeding and clamping operation.
