Description

Technical Field

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

[0002] Motorcycle brake pads, also known as motorcycle brake shoe blocks, are composed of two semi-circular metal structures, and friction blocks are arranged on their outer surfaces. The brake shoe blocks of motorcycles are one of the key components of the motorcycle braking system. They are located inside the brake calipers and contact the brake disc during braking operations to generate resistance through friction to decelerate or stop the motorcycle. Usually, when processing brake pads, in order to maintain the integrity, stability, and adaptability of the brake shoe blocks during later installation, the two semi-circular shoe blocks are usually placed together for processing.

[0003] In the prior art, such as the "motorcycle drum brake structure" with the Chinese patent number: CN220791850U, which includes a brake shoe block one, a brake shoe block two, a tension spring one, a tension spring two, a pivot pin, a brake camshaft, a backing plate, and a rocker arm. A first limiting groove is arranged on the outer side of the pivot pin. Although this technology can simulate the actual use state of the brake shoe block and design a fixture to grind the brake shoe block, improving the manufacturing and processing efficiency, there are still some defects in its actual use: when processing the shoe blocks, the two shoe blocks are placed together for processing and fixed together with a tension spring. Since the shoe blocks need to be disassembled and installed later, using a tension spring to fix the shoe blocks together in this technology makes it very troublesome to disassemble these shoe blocks later, and manual disassembly operations are required. This not only affects work efficiency but also causes inconvenience in operation and potential safety hazards. Content of the Utility Model

[0008] Preferably, a fixing block is fixedly connected to the top inside the fixing frame. The outer shape of the fixing block is U-shaped, and the position of the fixing block is at the top of the middle part of the connecting plate. Return springs are fixedly connected to both ends of the bottom of the fixing block. A connecting block is fixedly connected to the bottom end of the return spring. A buffer spring is fixedly connected to the bottom end of the connecting block. A pressing plate is fixedly connected to the bottom end of the buffer spring. The length of the pressing plate corresponds to the positions when the two shoe blocks are fixed inside the fixing ring.

[0009] Preferably, the bottoms of both ends of the pressing plate are fixedly connected with blocking blocks respectively.

The height of the blocking blocks is lower than the height of the bottoms of the first clamping plate and the second clamping plate, and when the shoe block moves to the bottom of the blocking block, it contacts the bottom of the blocking block.

[0010] Preferably, clamping grooves are formed at both ends of the bottom plate. The two pressing blocks are slidably connected inside the clamping grooves. When the two U-shaped cards are placed on the top of the bottom plate, the two pressing blocks are just clamped inside the U-shaped cards.

[0014] The beneficial effects of the present utility model:

[0015] 1. Through the provided disassembly component, the rapid disassembly of the shoe block can be effectively realized, improving the work efficiency and avoiding the trouble of traditional manual disassembly. During disassembly, the linear guide rail drives the bottom plate to move, prompting the fixed ring to drive the shoe block to move to the bottom of the first clamping plate. At this time, the air cylinder is started to prompt the connecting plate to drive the first clamping plate and the second clamping plate to move downward, and then the first clamping plate and the second clamping plate clamp both sides of the fixed ring. At this time, the air cylinder is started again to drive the connecting plate to move upward. At this time, due to the blocking effect of the blocking block, the fixed ring is separated from the outside of the shoe block, and then the shoe block falls off by itself, thus completing the rapid disassembly of the shoe block and avoiding the trouble of traditional manual disassembly.

[0016] By means of the provided auxiliary component, it can assist the disassembly component in disassembly, thereby making the disassembly of the shoe block smoother, improving work efficiency. When the connecting plate moves downward, the alignment cylinder drives the alignment rod to move downward simultaneously, so that the bottom of the alignment rod touches the top of the trigger rod, causing the trigger rod to drive the L-shaped rod to descend. At this time, the connecting plate drives one end of the first connecting rod to move downward, and at the same time, the other end of the first connecting rod is pulled to drive the second connecting rod to move downward, thus causing the sector gear to move the rack, and further causing the two pressing blocks to respectively push the two U-shaped clamps towards one end of the first spring. At this time, the U-shaped clamps will move away from one side of the shoe block, which facilitates the later removal of the fixing ring away from the shoe block, and the shoe block can smoothly disengage from one side of the U-shaped clamp and the fixing ring, thus avoiding the problem that the shoe block gets stuck on one side of the U-shaped clamp and cannot fall off.

[0027] Refer to the present utility model Figures 1 to 5The shown motorcycle shoe brake disassembly and assembly mechanism includes a base 1, shoe blocks 3 and a fixing ring 4. There are two shoe blocks 3, and the two shoe blocks 3 are sleeved at both ends inside the fixing ring 4. U-shaped clamps 5 are respectively clamped on one side of the two shoe blocks 3 away from the fixing ring 4. One side of the two U-shaped clamps 5 away from the shoe blocks 3 is connected by a first spring 6. A fixing frame 2 is fixedly connected to the top of the base 1. A linear guide rail 7 is fixedly connected inside the base 1. A disassembly component for disassembling the shoe blocks 3 inside the fixing ring 4 is arranged inside the fixing frame 2. The disassembly component includes a cylinder 18 fixedly connected to the top of the fixing frame 2. The output end of the cylinder 18 is fixedly connected with a connecting plate 21. First turning plates 22 are fixedly connected to the bottoms of both ends of the connecting plate 21. One side of the bottom of the first turning plate 22 is respectively rotatably connected with a first clamping plate 23 and a second clamping plate 24 through a shaft; the positions of the first clamping plate 23 and the second clamping plate 24 at the bottoms of both ends of the connecting plate 21 respectively correspond to the positions on both sides of the fixing ring 4. An auxiliary component for assisting the disassembly component to disassemble is arranged inside the base 1. The auxiliary component includes a moving block 8 slidably connected to the top of the linear guide rail 7. A bottom plate 9 is fixedly connected to the top of the moving block 8. An L-shaped rod 11 is slidably connected inside the moving block 8. One end of the L-shaped rod 11 is fixedly connected with a connecting plate 12. First connecting rods 13 are respectively rotatably connected to both ends of the connecting plate 12 through a shaft. One end of the first connecting rod 13 away from the connecting plate 12 is rotatably connected with a second connecting rod 14 through a shaft. One end of the second connecting rod 14 away from the first connecting rod 13 is fixedly connected with a sector gear 15. One side of the sector gear 15 is rotatably connected to one side inside the moving block 8. One end of the sector gear 15 is meshed with a rack 16. A pressing block 17 is fixedly connected to the top of the rack 16;

[0028] Through the arranged disassembly component, the rapid disassembly of the shoe blocks 3 can be effectively realized, the work efficiency is improved, and at the same time, the trouble of traditional manual disassembly is avoided. During disassembly, the linear guide rail 7 drives the bottom plate 9 to move, prompting the fixing ring 4 to drive the shoe blocks 3 to move to the bottom of the first clamping plate 23. At this time, the cylinder 18 is started to prompt the connecting plate 21 to drive the first clamping plate 23 and the second clamping plate 24 to move downward, and then the first clamping plate 23 and the second clamping plate 24 clamp both sides of the fixing ring 4. At this time, the cylinder 18 is started again to drive the connecting plate 21 to move upward. At this time, due to the blocking effect of the blocking block 34, the fixing ring 4 is separated from the outside of the shoe blocks 3, and then the shoe blocks 3 fall off by themselves, thus completing the rapid disassembly of the shoe blocks 3, and avoiding the trouble of traditional manual disassembly. At the same time, by setting the cooperation of the fixing ring 4 and the U-shaped clamps 5 to fix the two shoe blocks 3, the later disassembly is facilitated. During fixation, the two shoe blocks 3 are respectively clamped between the U-shaped clamps 5 and the fixing ring 4. At this time, due to the action of the first spring 6, the positions of the shoe blocks 3 are fixed, which facilitates the processing of the shoe blocks 3 in the early stage.

[0029] Such as Figure 1 、Figure 4 and Figure 5 As shown in Figure 5 , the outer shapes of the first clamping plate 23 and the second clamping plate 24 are L-shaped, and the positions of the first clamping plate 23 and the second clamping plate 24 are mirror-symmetrically arranged. An arc-shaped opening 26 is provided on the opposite side of the bottom of the first clamping plate 23 and the second clamping plate 24. The distance between the arc-shaped opening 26 at the bottom of the first clamping plate 23 and the arc-shaped opening 26 at the bottom of the second clamping plate 24 is greater than the thickness of the fixing ring 4. One side of the bottom of the first clamping plate 23 is fixedly connected to a second spring 25, and the side of the second spring 25 away from the first clamping plate 23 is fixedly connected to one side of the second clamping plate 24. The tops of both ends of the connecting plate 21 are fixedly connected to telescopic rods 20. A fixing cylinder 19 is sleeved outside the top of the telescopic rod 20, and the top of the fixing cylinder 19 is fixedly connected to the top inside the fixing frame 2;

[0030] By setting the outer shapes of the first clamping plate 23 and the second clamping plate 24 to be L-shaped and the second spring 25, when clamping the fixing ring 4, according to the lever principle, when the first clamping plate 23 and the second clamping plate 24 come into contact with the fixing ring 4, the bottoms of the first clamping plate 23 and the second clamping plate 24 will move away from each other. At this time, it causes the top of the fixing ring 4 to contact the inside of the first clamping plate 23 and the second clamping plate 24. At this time, through the action of the second spring 25, it causes the first clamping plate 23 and the second clamping plate 24 to clamp the fixing ring 4, thus facilitating the disassembly of the shoe block 3. At the same time, by setting the arc-shaped opening 26, the contact area between the first clamping plate 23 and the second clamping plate 24 and the fixing ring 4 can be increased, so that the first clamping plate 23 and the second clamping plate 24 can accurately clamp the fixing ring 4. At the same time, by setting the telescopic rod 20 and the fixing cylinder 19, it can play a role in stabilizing the connecting plate 21, avoiding the problem that when the air cylinder 18 drives the connecting plate 21 to descend, the connecting plate 21 moves, resulting in misalignment when the first clamping plate 23 and the second clamping plate 24 contact the fixing ring 4.

[0031] As Figure 1 and Figure 4 shown in Figure 4 , a fixing block 29 is fixedly connected to the top inside the fixing frame 2. The outer shape of the fixing block 29 is U-shaped, and the position of the fixing block 29 is located at the top of the middle part of the connecting plate 21. The two ends of the bottom of the fixing block 29 are fixedly connected to return springs 30. The bottom ends of the return springs 30 are fixedly connected to a connecting block 31. The connecting block 31 is located below the connecting plate 21. The bottom end of the connecting block 31 is fixedly connected to a buffer spring 32. The bottom end of the buffer spring 32 is fixedly connected to a pressing plate 33. The length of the pressing plate 33 corresponds to the position when the two shoe blocks 3 are fixed inside the fixing ring 4. The bottom parts of both ends of the pressing plate 33 are respectively fixedly connected to a resisting block 34. The outer shape of the resisting block 34 is arc-shaped, and the material of the resisting block 34 is rubber. The height of the resisting block 34 is lower than the height of the bottom ends of the first clamping plate 23 and the second clamping plate 24, and when the shoe block 3 moves to the bottom of the resisting block 34, it contacts the bottom of the resisting block 34;

[0032] By means of the arranged return spring 30, connecting block 31 and buffer spring 32, while playing a role in stabilizing the pressing plate 33, it can also prompt the blocking block 34 to buffer when contacting the shoe block 3. This not only avoids damage to the shoe block 3 caused by friction, but also enables the blocking block 34 to be used for a long time, avoiding the problem that the blocking block 34 is often squeezed and deformed. At the same time, the outer shape of the blocking block 34 is set to be arc-shaped and the material of the blocking block 34 is set to be rubber material. The arc shape can prompt the blocking block 34 to contact the shoe block 3 with the largest area, thereby prompting the shoe block 3 to be smoothly separated. At the same time, the rubber material can avoid the loss of the shoe block 3 caused by extrusion. At the same time, by setting the height of the blocking block 34, when the linear guide rail 7 drives the bottom plate 9 to move to the bottom of the blocking block 34, it just contacts the bottom of the blocking block 34. In this way, when the first clamping plate 23 and the second clamping plate 24 clamp the fixing ring 4, it is convenient for the blocking block 34 to resist the shoe block 3 and not move, thereby facilitating the disassembly of the shoe block 3.

[0033] As Figures 1 to 3 shown, slots are opened at both ends of the bottom plate 9, two pressing blocks 17 are slidably connected inside the slots. When two U-shaped cards 5 are placed on the top of the bottom plate 9, the two pressing blocks 17 are just clamped inside the U-shaped cards 5. One end of the L-shaped rod 11 far from the connecting plate 12 is fixedly connected with a trigger rod 10. The end of the trigger rod 10 far from the L-shaped rod 11 penetrates the top of the bottom plate 9, and the height of the trigger rod 10 penetrating the top of the bottom plate 9 is lower than the height of the fixing ring 4. The bottom of the connecting plate 21 is fixedly connected with an alignment cylinder 27. A third spring is fixedly connected inside the alignment cylinder 27. An alignment rod 28 is slidably connected inside the bottom end of the alignment cylinder 27. One end of the alignment rod 28 slidably connected inside the alignment cylinder 27 is fixedly connected with one end of the third spring. The position of the alignment rod 28 corresponds to the position of the trigger rod 10 when the bottom plate 9 moves to the bottom of the blocking block 34. The height of the bottom end of the alignment rod 28 is higher than the height of the bottom end of the second clamping plate 24;

[0034] By means of the provided auxiliary component, it can play a role in assisting the disassembly component to carry out disassembly, thereby making the disassembly of the shoe block 3 smoother, improving work efficiency. When the connecting plate 21 moves downward, the alignment cylinder 27 drives the alignment rod 28 to move downward simultaneously, thereby causing the bottom of the alignment rod 28 to contact the top of the trigger rod 10, prompting the trigger rod 10 to drive the L-shaped rod 11 to descend. At this time, the connecting plate 12 drives one end of the first connecting rod 13 to move downward, and at the same time, the other end of the first connecting rod 13 is prompted to pull the second connecting rod 14 downward, thereby causing the sector gear 15 to move the rack 16, and further causing the two pressing blocks 17 to respectively push the two U-shaped clamps 5 towards one end of the first spring 6. At this time, the U-shaped clamp 5 will move away from one side of the shoe block 3, which facilitates the later removal of the fixing ring 4 away from the shoe block 3. The shoe block 3 can smoothly disengage from one side of the U-shaped clamp 5 and the fixing ring 4, thus avoiding the problem that the shoe block 3 cannot fall off when stuck on one side of the U-shaped clamp 5. At the same time, by arranging a spring inside the alignment cylinder 27 and setting the height of the bottom end of the alignment rod 28 and the top end of the trigger rod 10, and setting the height of the alignment rod 28, it is convenient for the first clamping plate 23 and the second clamping plate 24 to clamp. By setting the height of the trigger rod 10, it is convenient for the linear guide rail 7 to drive the shoe block 3 to move to the bottom of the first clamping plate 23, avoiding the problem that the trigger rod 10 blocks the movement of the shoe block 3. At the same time, by arranging a spring inside the alignment cylinder 27, when the first clamping plate 23 and the second clamping plate 24 clamp the fixing ring 4, the bottom of the alignment rod 28 will first contact the top of the trigger rod 10 and cause the trigger rod 10 to move downward. At this time, when the first clamping plate 23 and the second clamping plate 24 move upward, due to the action of the spring extrusion, the alignment rod 28 will contact and press the top end of the trigger rod 10, which facilitates the clamping of the first clamping plate 23 and the second clamping plate 24, thus avoiding the problem that the trigger rod 10 rises before the fixing ring 4 disengages from the shoe block 3, resulting in the return of the pressing block 17.

[0035] As Figure 1 shown, two L-shaped baffles 35 are fixedly connected to the top inside the fixing frame 2. The positions of the L-shaped baffles 35 are between the first clamping plate 23 and the second clamping plate 24 and on one side of the second spring 25, and the height of the bottom end of the L-shaped baffle 35 is higher than the height of the bottom end of the alignment rod 28;

[0036] By arranging the L-shaped baffle 35, when the first clamping plate 23 and the second clamping plate 24 clamp the fixing ring 4 and move upward, when moving to the bottom end of the L-shaped baffle 35, the bottom of the L-shaped baffle 35 will contact the top of the fixing ring 4, thereby causing the L-shaped baffle 35 to push the fixing ring 4 out of the inside of the first clamping plate 23 and the second clamping plate 24, which facilitates the automatic disengagement of the fixing ring 4 from the clamping of the first clamping plate 23 and the second clamping plate 24, and at the same time drops to the top of the bottom plate 9, thus facilitating the fixation of the next shoe block 3.
