Problems solved by technology

This installation method can easily make the spring coil not within the elastic range after being enlarged, so that when the hand pliers tighten the spring coil, the spring coil cannot be completely restored. When the spring coil is expanded with hand pliers, the spring coil is partially deformed due to uneven force, In this way, the use effect or service life of the spring coil will be limited, and this assembly method is inefficient

Embodiment Construction

[0010] The present invention will be further described below in conjunction with specific examples.

[0011] see figure 1 and figure 2 , the spring coil installer includes a frustum-shaped guide body 1 and a push cylinder 3 that is clearance fit with the guide body 1, and the inner diameter of the push cylinder 3 is slightly larger than the maximum diameter of the guide body 1 and smaller than the Install the outer diameter of spring ring 9, the minimum diameter of described guide body 1 is less than the internal diameter of installed spring ring 9, and described guide body 1 is a small taper circular platform; The maximum diameter of described guide body 1 is slightly larger than the desired installation spring ring. The shaft diameter of the shaft, and on the end surface of the largest diameter of the guide body 1, there is a connecting threaded post 8, which is coaxial with the guide body 1.

[0012] This example is further explained by installing the spring ring 9 on th...

Abstract

The invention discloses a mounting tool for a spring ring. The mounting tool comprises a guiding body and a pushing sleeve, wherein the guiding body has a shape of circular platform; the pushing sleeve is in clearance fit with the guiding body; an inner diameter of the pushing sleeve is slightly more than a maximum diameter of the guiding body and is less than an outer diameter of a mounted spring ring; a minimum diameter of the guiding body is less than an inner diameter of the mounted spring ring; the guiding body is a circular platform at a small conical degree; the maximum diameter of the guiding body is slightly more than the diameter of an axle of the mounted spring ring; a connecting threaded pillar is arranged on an end face of a maximum-diameter end of the guiding body; and the threaded pillar is coaxial with the guiding body. The mounting tool for the spring ring has a simple structure, is portable and conveniently used, is capable of flexibly moving and can be used for mounting the spring ring. Under the guidance of the guiding body, the spring ring is uniformly expanded, thereby avoiding a situation of serious local deformation of the spring ring caused by an unevenly pressed local part, ensuring the precision of the outer surface of the axle of the mounted spring ring, and improving the service life of the spring ring and assembling efficiency.

Description

technical field [0001] The invention relates to an assembly tool, in particular to a spring coil installer. Background technique [0002] When the current coils are installed, the diameter of the coils is generally enlarged by means of hand pliers, then it is inserted in the groove where the coils need to be installed, and finally it is tightened with the clamps. This installation method can easily make the spring coil not within the elastic range after being enlarged, so that when the hand pliers tighten the spring coil, the spring coil cannot be completely restored. When the spring coil is expanded with hand pliers, the spring coil is partially deformed due to uneven force, In this way, the use effect or service life of the spring ring will be limited, and this assembly method is inefficient. Contents of the invention [0003] In view of the shortcomings of the prior art above, the present invention aims to provide a spring coil installer for quickly installing the spri...
