Technical Field
[0001] This utility model relates to the technical field of retaining ring removal tools, specifically to a retaining ring removal pliers suitable for self-locking elastic retaining rings. Background Technology
[0002] Self-locking elastic retaining rings (refer to the self-locking anti-disengagement elastic retaining ring disclosed in Chinese invention patent application number 202310808669.2) can prevent external expansion and disengagement during high-speed rotation. When disassembling self-locking elastic retaining rings, traditional retaining ring removal pliers (such as the shaft elastic retaining ring installation pliers disclosed in mechanical industry standard JB-T3411.47-1999) cannot directly remove the self-locking elastic retaining ring. Therefore, a retaining ring removal pliers are urgently needed to accommodate the disassembly of self-locking elastic retaining rings. Utility Model Content

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0005] A retaining ring removal pliers for self-locking resilient retaining rings, comprising:
[0006] A pair of pivotally connected clamp bodies, each end of which is provided with a clamp head and a drive unit; each clamp head is provided with a connecting structure, which is used to drively connect to the ends on both sides of the opening position of the elastic retaining ring; the drive unit is used to operate the pair of clamp bodies to rotate relative to each other. During the relative rotation of the pair of clamp bodies in a preset rotation direction, the clamp heads can open at least in the radial direction of the corresponding elastic retaining ring, so as to drive the ends on both sides of the opening position of the elastic retaining ring to separate in the radial direction of the corresponding elastic retaining ring through the connecting structure.
[0007] Furthermore, in the reset state, a pair of connecting structures can be connected to the ends on both sides of the opening position of the elastic retaining ring in the present application for a retaining ring removal pliers. At this time, the pair of pliers heads have a preset interval at least in direction A, and direction A is parallel to the rotation axis of the pliers body.
[0008] Furthermore, in the present application, a retaining ring removal pliers applicable to self-locking elastic retaining rings is provided, in the reset state, one end of the corresponding drive part of a pair of clamps is in an open state; during the process of the pair of clamps rotating relative to each other in a preset rotation direction, the pair of drive parts move in a mating direction.
[0009] Furthermore, one of the retaining ring removal pliers in this application is suitable for self-locking elastic retaining rings, and its connecting structure is a rod.
[0010] Furthermore, in this application, a retaining ring removal pliers suitable for self-locking elastic retaining rings has a connecting structure that extends towards the rotation axis of the pliers body in the direction of the pliers head.
[0011] Furthermore, in the present application, a retaining ring removal pliers suitable for self-locking elastic retaining rings has a pair of pliers heads spaced apart in direction A when in the reset state.
[0012] Furthermore, in this application, a retaining ring removal pliers applicable to self-locking elastic retaining rings has an operating handle as its driving part.
[0013] Furthermore, in this application, a retaining ring removal pliers suitable for self-locking elastic retaining rings is provided with an extension portion on the pliers body extending in a direction parallel to the rotation axis of the pliers body, and the pliers head is disposed on the extension portion.
[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects:
[0015] This application provides a retaining ring removal pliers suitable for self-locking elastic retaining rings. In use, a pair of connecting structures are first connected to the ends on both sides of the opening position of the elastic retaining ring. The driving unit is operated to make the pair of pliers rotate relative to each other in a preset rotation direction. The ends on both sides of the opening position of the elastic retaining ring open in the radial direction, causing the self-locking to fail, thereby enabling the retaining ring to be removed from the mounting shaft and improving the retaining ring removal efficiency.

[0022] like Figures 1 to 3 The retaining ring removal pliers shown include:
[0023] A pair of pivotally connected clamp bodies 1, each end of which is provided with a clamp head 11 and a drive unit; each clamp head 11 is provided with a connecting structure 111, which is used for transmission connection with the ends on both sides of the opening position of the elastic retaining ring; the drive unit is used to operate the pair of clamp bodies 1 to rotate relative to each other, such that during the relative rotation of the pair of clamp bodies 1 in a preset rotation direction, ... Figure 4 The pair of clamps 11 shown can open at least in the radial direction of the corresponding elastic retaining ring, so as to drive the ends on both sides of the opening position of the elastic retaining ring through the connecting structure 111. Figure 5 As shown, they separate in the radial direction of the corresponding elastic retaining ring.
[0024] Based on the above-mentioned device, this application provides a retaining ring removal pliers suitable for self-locking elastic retaining rings. In use, a pair of connecting structures 111 are first connected to the ends on both sides of the opening position of the elastic retaining ring (refer to the first end and second end of a self-locking elastic retaining ring in prior art patent 202310808669.2); the driving unit is operated to make the pair of clamp bodies 1 rotate relative to each other in a preset rotation direction, and the ends on both sides of the opening position of the elastic retaining ring open in the radial direction, so that the self-locking is invalidated, thereby enabling the retaining ring to be removed from the mounting shaft, improving the retaining ring removal efficiency.
[0025] In this embodiment, in the reset state, a pair of connecting structures 111 can be connected to the ends on both sides of the opening of the elastic retaining ring. At this time, the pair of clamp heads 11 have a preset interval at least in direction A, and direction A is parallel to the rotation axis of the clamp body 1. Specifically, in the reset state, the pair of clamp heads 11 are spaced apart in direction A.
[0026] In this embodiment, in the reset state, one end of the drive unit corresponding to the pair of clamps 1 is in an open state; during the process of the pair of clamps 1 rotating relative to each other in a preset rotation direction, the pair of drive units move in a closing direction.
[0027] In this embodiment, the connecting structure 111 is a rod. It is used to insert into the disassembly hole of a self-locking elastic retaining ring as described in prior art patent 202310808669.2. Specifically, as... Figure 3 As shown, the connecting structure 111 extends towards the clamp head 11 and is aligned with the rotation axis of the clamp body 1.
[0028] In this embodiment, the driving unit is the operating handle 12.
[0029] In this embodiment, the clamp body 1 is provided with an extension portion 13 extending along the direction parallel to the rotation axis of the clamp body 1, and the clamp head 11 is disposed on the extension portion 13. This is to avoid interference caused by excessively large clamp body volume and to adapt to compact installation space.
[0030] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on the explanation herein, those skilled in the art can conceive of other specific embodiments of this utility model without creative effort, and these embodiments will all fall within the scope of protection of this utility model.
