An installation tool for automatic guiding and limiting of steel wire retaining ring for holes

Abstract

The invention belongs to the technical field of tooling assembly, and relates to an installation tool for automatically guiding and limiting a steel wire retaining ring for a hole, comprising an end seat (1), a screw rod (2), a pressure sleeve (3), a guide sleeve (4), and an installation sleeve (5), pin (6), nut (7); the smooth surface of the right end of the end seat (1) is used for part positioning, the screw (2) and pin (6) are installed on the end seat (1), and the pressure sleeve (3) Set on the screw rod (2), limit the installation sleeve (5), the installation sleeve (5) limit the guide sleeve (4), the guide sleeve (4) limit the steel wire retaining ring, the nut (7) It is installed on the screw rod (2) through threaded connection, and the pressure sleeve (3) and the installation sleeve (5) are driven by the screw transmission between the two to realize the assembly of the steel wire retaining ring. Utilize the transfer positioning guide between the positioning shaft and the positioning sleeve, and convert the helical movement of the thread into axial displacement and compression, so as to realize the compression of the spring seat and spring and the positioning and movement of the wire retaining ring.

Description

technical field [0001] The invention belongs to the field of tooling assembly technology, and relates to the assembly technology of a hydraulic mechanical actuator of an aero-engine fuel control system, in particular to an installation tool for automatic guiding and positioning of a steel wire retaining ring for a hole, which can realize rapid positioning and installation. Background technique [0002] The retaining ring, also known as the retaining ring, is divided into the retaining ring for the hole and the retaining ring for the shaft, which acts as an axial limit and can prevent other parts from moving axially. For general retaining rings, snap ring pliers can be used to install them, while wire retaining rings (schematic diagram as figure 1 As shown) there is no good point of force, the elasticity is small, and it is easy to slip or even break with ordinary installation methods, and may damage the assembly parts. When assembling, the spring 10 and the spring seat 9 nee...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing installation tools have problems such as poor positioning effect, large compression deformation of the steel wire retaining ring, difficult operation during installation and use, and adjustment after installation.
