Problems solved by technology

With the conventional processing method, the elasticity of the part after processing is not good, and the shrinkage of the inner holes at both ends is not enough, which affects the working effect. In order to improve the processing situation, the nuclear power elastic jacket and its processing method are developed.

Abstract

The invention discloses a method for machining elastic nuclear power jackets, and relates to a method for machining elastic nuclear power jackets. The method includes steps of firstly, preparing materials; secondly, carrying out rough lathing; thirdly, carrying out heat treatment; fourthly, grinding inner holes; fifthly, grinding outer circular surfaces; sixthly, scribing open slots; seventhly, linearly cutting the various open slots; eighthly, fixedly clamping clips; ninthly, carrying out tempering heat treatment; tenthly, carrying out rounding, to be more specific, detaching the clips 5 at two ends of each elastic jacket by the aid of bench workers and rounding various edges to completely machine the elastic jackets. The method has the advantages that problems of poor elasticity of elastic jackets in the prior art, insufficient shrinkage of inner holes in two ends of each elastic jacket and influence on work effects can be solved by the aid of the method; the method is applied to the field of components of nuclear power welding machines.

Description

technical field [0001] The invention relates to a processing method of a nuclear power elastic jacket. Background technique [0002] The elastic collet is a working part of the nuclear power welding machine. It is elastically clamped during work. This part will have two processing difficulties. One is that it must have sufficient elasticity during work. It meets the working requirements of locking the inner holes at both ends. With the conventional processing method, the elasticity of the part after processing is not good, and the shrinkage of the inner holes at both ends is not enough, which affects the working effect. In order to improve the processing situation, the nuclear power elastic jacket and its processing method are developed. Contents of the invention [0003] The invention aims to solve the problem of poor elasticity of the elastic jacket in the prior art and insufficient shrinkage of the inner holes at both ends, which affects the working effect, and further...
