Abstract
The invention provides a machining process of a self-locking air spring and relates to the technical field of production of air springs. In the invention, a valve body blank and a hollow piston rod are welded into a whole by friction and then machining. Because friction welding is adopted, defects of the process of the self-locking air spring can be effectively overcome, and the concentricity and the connecting strength of a valve body and the hollow piston rod can be effectively ensured. According to the process disclosed by the invention, the processing precision of the self-locking air spring can be improved; and since a machining method of multi-components assembly and riveting is cancelled, the steps can be simplified, and the production efficiency can be improved.
Description
Technical field
The present invention relates to the production technical field of air spring.
Background technology
At present, the self-locking type air spring is that pressing by equipment was integral again after the valve body of inside (being piston) and hollow piston bar were processed.The big accumulated error of the system of leading, concentricity can not get effective assurance, directly influences product quality.
Summary of the invention
The object of the invention is to propose a kind of processing technology that can effectively improve the self-locking type air spring of valve body and hollow piston bar concentricity.
The present invention is integrally welded with valve body blank and the friction of hollow piston bar earlier, and then carries out machining.
The present invention adopts the friction weldering, can effectively overcome the deficiency of the above-mentioned technology of self-locking type air spring, can effectively ensure the concentricity and the bonding strength of valve body and hollow piston bar.This technology can be improved self-locking type air spring machining accuracy, because the processing method of the many part assemblings of cancellation riveted joint can be simplified working process, enhances productivity.
The specific embodiment
1, blanking
Need obtain valve body blank and hollow piston bar blank by design respectively.
2, welding
Valve body blank and hollow piston bar is integrally welded by friction.
3, machining.
Claims (1)
1. the processing technology of a self-locking type air spring is integrally welded with valve body blank and the friction of hollow piston bar earlier, and then carries out machining.
