Description

Technical Field

[0001] This utility model belongs to the field of chain disassembly and assembly, and particularly relates to a fixing fixture structure for disassembling links of transmission chains. Background Technology

[0002] Chain drives are a primary transmission method in various workshop machines. They are reliable, efficient, and suitable for humid and dusty working environments. After prolonged use, chains will experience wear and tear, requiring disassembly, repair, or replacement of the entire chain or some chain links. Although the reinstalled chain links may be of the same specifications, the chain length often does not match the sprocket. This necessitates removing one or more excess chain links. If the chain links are removed before installation, the chain installation becomes difficult and prone to damage. Therefore, in actual production, the chain is usually installed first, and then the excess chain links are removed. That is, one or more chain links are removed without disassembling the entire chain. However, the limited space at the chain installation location makes the chain link removal process difficult, labor-intensive, and inefficient.

[0003] For example, a Chinese utility model patent discloses a disassembly tool for a transmission chain link [application number: CN202321094646.1]. This utility model patent includes a fixed box, a hand-held handle connected to the bottom of the fixed box, two movable plates on the fixed box, an mounting plate on the top of the movable plates, and a second threaded sleeve on the mounting plate, one of which has an ejector threaded rod installed inside.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] This embodiment provides a fixing fixture structure for disassembling transmission chain links, combined with... Figure 1-3 As shown, the device includes an operating table 10, on which two support frames 11 are provided, forming a placement space between the two support frames 11. One support frame 11 is fixed on the operating table 10, and the other support frame 11 is slidably disposed on the operating table 10. The support frame 11 slidably disposed on the operating table 10 is provided with a first ejection hole 12. The side of the support frame 11 fixed on the operating table 10 away from the other support frame 11 is provided with an ejection frame 13. A top shaft 14 is slidably disposed on the ejection frame 13, and the position of the top shaft 14 corresponds to the first ejection hole 12.

[0021] In this embodiment, the transmission chain is placed between two support frames 11. One support frame 11 is moved closer to the other support frame 11 to clamp the transmission chain between the two support frames 11, so that one end of the pin on the transmission chain is aligned with the first ejection hole 12 and the other end is aligned with the top shaft 14. Then the top shaft 14 moves to push the pin on the transmission chain out of the transmission chain and into the first ejection hole 12.

[0022] The ejector frame 13 is provided with a second ejector hole 15. One end of the ejector shaft 14 extends out of the second ejector hole 15 and is screwed to the second ejector hole 15. The end holes of the first ejector hole 12 and the second ejector hole 15 that are close to each other are provided with a placement ring 16. The placement ring 16 is provided with a placement groove. The diameter of the placement groove is larger than the diameter of the ejector hole.

[0023] In this embodiment, when the transmission chain is placed between the two support frames 11, the connecting joint on the transmission chain is placed in the placement groove of the placement ring 16. During the process of the top shaft 14 pushing the pin, the placement ring 16 can lock the transmission chain by locking the connecting joint to prevent it from shaking.

[0024] The first ejection hole 12 is disposed in the first vertical moving block 17, the first vertical moving block 17 is connected to the linear driver and slides vertically on the support frame 11, the top shaft 14 is disposed on the second vertical moving block 18, the second vertical moving block 18 is connected to the linear driver and slides vertically on the ejection frame 13.

[0025] In this embodiment, the height of the first ejector hole 12 and the top shaft 14 can be adjusted according to the height of the pin on the transmission chain to accommodate transmission chains of different sizes.

[0026] The height of the support frame 11 fixedly mounted on the operating table 10 is lower than the height of the other support frame 11. The second vertical moving block 18 is located above the support frame 11 fixedly mounted on the operating table 10, and there is a gap between the second vertical moving block 18 and the support frame 11 below.

[0027] In this embodiment, since the support frame 11 fixed on the operating table 10 is relatively low, the second vertical moving block 18 has a larger moving space, which improves adaptability.

[0028] The support frame 11 is provided with a pushing structure.

[0029] In this embodiment, after clamping the transmission chain, the pushing structure can push the transmission chain to further align the pin with the first ejection hole 12 and the top shaft 14. After ejecting the pin, the pushing structure can move the processed transmission chain out of the support frame 11.

[0030] The support frame 11 has a cavity 19, and two rotating rollers 20 are rotatably arranged in the cavity 19. At least one rotating roller 20 is connected to a drive motor, and a drive belt 21 is sleeved between the two rotating rollers 20.

[0031] The cavity 19 has a backing plate 22 fixed on the support frame 11 on the side near the other support frame 11. The two ends of the backing plate 22 are respectively provided with connecting grooves 23 that communicate with the cavity 19. The driving belt 21 passes through the two connecting grooves 23 and abuts against the backing plate 22.

[0032] In this embodiment, the abutment 22 is used to support the drive belt 21 and clamp the transmission chain. When clamping the transmission chain, the position of the drive belt 21 is not shifted.

[0033] The support frame 11 and the ejector frame 13 extend into the operating table 10 and are slidably connected to the operating table 10 via a linear drive.

[0034] The placement slots are interconnected.

[0035] In this embodiment, during the movement of the transmission chain, the connector on the transmission chain is not restricted by the placement groove and can move back and forth. The specific embodiments described herein are merely illustrative examples of the spirit of this utility model. Those skilled in the art to which this utility model pertains can make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0036] Although this article frequently uses terms such as operating table 10, support frame 11, first ejection hole 12, ejection frame 13, top shaft 14, second ejection hole 15, placement ring 16, first vertical moving block 17, second vertical moving block 18, cavity 19, rotating roller 20, driving belt 21, abutment plate 22, connecting groove 23, etc., these terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would be contrary to the spirit of this utility model.
