Description

Detachable elastic pin

Technical Field

The utility model relates to the technical field of elastic pin disassembly and assembly, in particular to a detachable elastic pin.

Background

The elastic pin is commonly used for positioning and fixing an operating mechanism of an automobile transmission and a differential gear shaft, and is an important connecting piece; the shapes of workpieces connected by the elastic pins are different, so that in the initial stage of development and trial production of the automobile transmission, the elastic pins cannot be pressed by a conventional press due to the structural limitation of transmission parts, and a large amount of manual disassembly and assembly are often required; the common elastic pin is not provided with a leading-in head, and when the elastic pin is pressed into the pin hole, the outer diameter of the elastic pin is larger than the aperture of the pin hole, so that the elastic pin is in interference fit with the pin hole. When the hammer or the metal rod is used for auxiliary assembly, the elastic pin is not positioned stably and stressed uniformly, so that the elastic pin is sometimes damaged or a workpiece is damaged, and even the hand is damaged because the elastic pin is knocked at the hand. When the elastic pin is knocked, an elastic pin striking rod is commonly used, and one end of the elastic pin striking rod is provided with a blind hole; when the elastic pin is removed, an elastic pin ejector rod is usually used. During assembly, the blind hole at one end of the elastic pin striking rod is firstly used, and then the elastic pin is struck to the bottom by replacing the other end. The following problems exist in the assembly of the elastic pin striking rod: 1. when the elastic pin is pressed, one end of the elastic pin striking rod provided with the blind hole cannot press the elastic pin to the bottom at one time, and the other end of the elastic pin striking rod needs to be replaced by a flat end for striking, so that the time is occupied; 2. the second point is that when the flat end of the elastic pin striking rod is used for striking the elastic pin, the elastic pin striking rod is easy to slip, so that the elastic pin or a workpiece is damaged, and even the hand is struck to cause work injury.

Through retrieval, the patent with the Chinese patent grant number of CN205166823U discloses an elastic pin removing tool, and relates to the technical field of elastic pin removing tools, comprising a clamping plate (1) and a combined screw rod; the combined screw is mainly composed of a screw (2) and a nut (3); the clamping plate (1) is provided with a perforation (4); the screw (2) passes through the perforation (4) and is matched with the nut (3) to combine the clamping plates (1) together and form a clamping plate combination seam; the middle part of the clamping plate (1) is provided with a pin dismounting groove (5); an adapter ring (6) is arranged in the pin dismounting groove (5). The clamping plate is simple in structure, after the clamping plates are clamped by the combined screw, the diameter of the elastic pin can be reduced, the friction force between the elastic pin and a workpiece is reduced, and the elastic pin is convenient to pull out; and the universality is strong, the adaptation rings with different thicknesses can be selected, the elastic pins with different diameters are removed by using the same tool, and the device can apply pressure to a workpiece in the process of pulling out the elastic pins conveniently although the elastic pins are convenient to pull out and the universality is strong in the prior art, so that the workpiece is damaged easily.
