Description

Technical Field

[0001] This utility model relates to the field of clutch assembly, specifically to a clutch spacer disassembly device. Background Technology

[0002] In the automotive parts manufacturing industry, disassembling clutch spacers is a relatively complex process. Clutch assembly inevitably involves rework and disassembly, and the disassembly process largely determines the condition of the parts to be repaired. Therefore, it is essential to ensure the integrity of the parts as much as possible during disassembly.

[0003] Currently, the industry typically uses a split-type puller structure to disassemble the clutch spacer. This involves using a slot or serrated structure on the inside of the puller claw to fix it to the edge of the clutch spacer, and then separating the spacer from the clutch by axial pulling.

[0004] However, the split-type Lamb structure is not compatible with multiple specifications, and its installation and adjustment process is relatively complicated. During the axial pulling process, the claw may shift, which may lead to damage to the spacer ring. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a clutch spacer disassembly device, which aims to solve the problems that the current split-type puller structure cannot be compatible with multiple specifications, its installation and adjustment process is relatively cumbersome, and the puller may deviate during the axial pulling process, thus causing damage to the spacer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clutch spacer disassembly device, comprising a push rod mechanism, a rocker arm mechanism mounted on the push rod mechanism, and a gripping mechanism;

[0007] The push rod mechanism includes a screw rod, a positioning sleeve sleeved on the screw rod, and a push block disposed at one end of the screw rod;

[0008] The gripping mechanism includes a connecting frame disposed on the circumferential surface of the positioning sleeve and a plurality of hooks evenly distributed along the circumference of the connecting frame.

[0009] In this configuration, several of the hooks are wound around the top block. The rocker arm mechanism first drives the screw to rotate, so that the top block opens the hooks and hooks them inside the clutch spacer. The rocker arm mechanism then drives the positioning sleeve to rotate, so that the hooks move along the screw axis, thereby causing the clutch spacer to disengage.

[0010] In summary, the clutch spacer disassembly device proposed in this utility model involves rotating a screw to bring a top block against the end face of the clutch drive disc. Simultaneously, the hooks open to engage the inner side of the clutch spacer, driving the positioning sleeve upwards and the hooks along the screw axial direction, thus disengaging the spacer. Because the top block simultaneously lifts the hooks, the inner side of the spacer experiences uniform force, preventing damage. Specifically, the push rod mechanism includes a screw, a positioning sleeve fitted on the screw, and a top block at one end of the screw; the gripping mechanism includes a connecting frame on the circumferential surface of the positioning sleeve and several hooks evenly distributed along the circumference of the connecting frame; the hooks are wound around the top block. A rocker arm mechanism first drives the screw to rotate, causing the top block to open the hooks and engage them inside the clutch spacer. The rocker arm mechanism then drives the positioning sleeve to rotate, causing the hooks to move along the screw axial direction, thereby disengaging the clutch spacer.

[0011] According to one aspect of the above technical solution, the screw includes a first rotating part for movably connecting with the rocker arm mechanism, and a threaded part passing through the positioning sleeve, wherein the first rotating part is engaged with the rocker arm mechanism.

[0012] According to one aspect of the above technical solution, the positioning sleeve includes a second rotating part movably connected to the rocker arm mechanism and a circumferential part passing through the connecting frame. A cover plate is also provided at one end of the circumferential part away from the second rotating part, and the cover plate is fixedly connected to the circumferential part.

[0013] According to one aspect of the above technical solution, the rocker arm mechanism includes a first rocker arm that is engaged with a first rotating part and a second rocker arm that is engaged with a second rotating part, and the end of the first rocker arm away from the first rotating part is also provided with a handle.

[0014] According to one aspect of the above technical solution, the first rotating part and the second rotating part are square columns.

[0015] According to one aspect of the above technical solution, the connecting frame extends outward with several connecting pieces, and a hook is provided between two of the connecting pieces.

[0016] According to one aspect of the above technical solution, the hook and the connecting piece are connected by a pivot pin.

[0017] According to one aspect of the above technical solution, each of the hooks has a circular groove recessed at the same position, and an O-ring is provided on the circular groove of the plurality of hooks.

[0028] Please see Figures 1-4 The diagram shows a schematic representation of a clutch spacer disassembly device according to an embodiment of the present invention. The clutch spacer disassembly device includes a push rod mechanism 100, a rocker arm mechanism 200 mounted on the push rod mechanism 100, and a gripping mechanism 300, wherein:

[0029] In order to bring the gripping mechanism 300 into the clutch to separate the clutch spacer 500, the push rod mechanism 100 includes a screw 110, a positioning sleeve 120 sleeved on the screw 110, and a top block 130 provided at one end of the screw 110. In this embodiment, in order to facilitate the rocker arm mechanism 200 to drive the screw 110 to rotate, the screw 110 is provided with a first rotating part 111 for movably connecting with the rocker arm mechanism 200, and a threaded part 112 passing through the positioning sleeve 120 and movably connected to the positioning sleeve 120. The screw 110 is engaged with the rocker arm mechanism 200 through the first rotating part 111.

[0030] Furthermore, to facilitate the rotation of the positioning sleeve 120 by the rocker arm mechanism 200, the positioning sleeve 120 includes a second rotating part 121 movably connected to the rocker arm mechanism 200 and a circumferential part 122 passing through the connecting frame 310. The rocker arm mechanism 200 can engage with the second rotating part 121 to drive the positioning sleeve 120 to rotate on the screw connection part 112. It is worth noting that the screw 110 is recessed inward to form a square column (i.e., the first rotating part 111), and similarly, the positioning sleeve 120 is recessed inward to form a square column (i.e., the second rotating part 121). By engaging the rocker arm mechanism 200 on the first rotating part 111 and the second rotating part 121, the screw 110 and the positioning sleeve 120 are driven to rotate.

[0031] To drive the screw 110 and the positioning sleeve 120 to rotate, the rocker arm mechanism 200 includes a first rocker arm 210 that engages with the first rotating part 111, and a second rocker arm 230 that engages with the second rotating part 121. The end of the first rocker arm 210 away from the first rotating part 111 is also provided with a handle 220. Both the first rocker arm 210 and the second rocker arm 230 are provided with square holes for respectively adapting and engaging with the first rotating part 111 and the second rotating part 121. Furthermore, the length of the first rocker arm 210 is greater than the length of the second rocker arm 230. Based on the lever principle, only a small stress needs to be applied to the first rocker arm 210 to rotate it and drive the top block 130 downwards, so that the top block 130, while adhering to the end face of the clutch drive disc, simultaneously opens the gripping mechanism 300.

[0032] According to one aspect of the above technical solution, the gripping mechanism 300 includes a connecting frame 310 disposed on the circumferential surface of the positioning sleeve 120, and a plurality of hooks 320 evenly distributed along the circumference of the connecting frame 310. The connecting frame 310 extends outwards with a plurality of connecting pieces 311, and a hook 320 is disposed between two connecting pieces 311. The hooks 320 and the connecting pieces 311 are movably connected by pivot pins 312. Each hook 320 has a recessed circular groove 321 at the same position, and an O-ring 330 is disposed on the circular groove 321 of the plurality of hooks 320. Since a thrust bearing 400 is fitted at the bottom of the positioning sleeve 120, and the thrust bearing 400 connecting frame 310 is disposed above the thrust bearing 400, the arrangement of the thrust bearing 400 allows the connecting frame 310 to move with reduced effort and prevents the hooks 320 from rotating, only moving axially along the screw 110.

[0033] The O-ring 330 is fitted around the three hooks 320 in this embodiment, constraining the hooks 320 from being in a free and loose state, facilitating synchronous opening. The O-ring 330 is an elastic element, so that when the top block 130 moves downward to push open the hooks 320, the hooks 320 can slowly open and hook onto the inner side of the clutch spacer 500 at the same speed, ensuring that the inner side of the clutch spacer 500 is subjected to uniform force, avoiding damage, and ensuring that the clutch spacer 500 does not affect secondary use after separation.

[0034] In addition, a cover plate 123 is fixedly provided at the bottom of the circumferential part 122 of the positioning sleeve 120, which not only prevents the internal components from falling off, but also provides a certain support for the connecting frame 310.

[0035] The working principle of the clutch spacer 500 disassembly device in this example:

[0036] By cranking the handle 220, the first rocker arm 210 is rotated, which in turn moves the screw 110 downward. At this time, the top block 130 pushes open the hook 320, so that the hook 320 hooks the inner side of the clutch spacer 500. Continue to rotate the first rocker arm 210 until the top block 130 is pressed against the end face of the clutch drive disc, generating a downward pushing force. At this time, the first rocker arm 210 is fixed. Since the positioning sleeve 120 is rotatably connected to the screw connection 112, the second rocker arm 230 is rotated to drive the positioning sleeve 120 upward. The cover plate 123 pushes the connecting frame 310 upward. The connecting frame 310 drives the hook 320 to move axially along the screw 110, thereby separating the clutch spacer 500 from the clutch. After disassembly, the clutch spacer 500 and the hook 320 are taken out together. The screw 110 is driven in the opposite direction, and the O-ring 330 springs back, so that the hook 320 is reset. The clutch spacer 500 can then be removed.

[0037] In summary, the clutch spacer disassembly device proposed in this utility model involves rotating a screw to bring a top block against the end face of the clutch drive disc. Simultaneously, the hooks open to engage the inner side of the clutch spacer, driving the positioning sleeve upwards and the hooks along the screw axial direction, thus disengaging the spacer. Because the top block simultaneously lifts the hooks, the inner side of the spacer experiences uniform force, preventing damage. Specifically, the push rod mechanism includes a screw, a positioning sleeve fitted on the screw, and a top block at one end of the screw; the gripping mechanism includes a connecting frame on the circumferential surface of the positioning sleeve and several hooks evenly distributed along the circumference of the connecting frame; the hooks are wound around the top block. A rocker arm mechanism first drives the screw to rotate, causing the top block to open the hooks and engage them inside the clutch spacer. The rocker arm mechanism then drives the positioning sleeve to rotate, causing the hooks to move along the screw axial direction, thereby disengaging the clutch spacer.
