New energy automobile universal shaft recycling and remanufacturing repair process

Abstract

The invention provides a new energy automobile universal shaft recycling and remanufacturing repair process, and relates to the technical field of universal shaft recycling and machining. The new energy automobile universal shaft recycling and remanufacturing repair process comprises the following steps that S1, ultrasonic rust removal is carried out, specifically, a plurality of recycled universal shafts are put into an ultrasonic rust removal pool, and the surface of each universal shaft is subjected to rust removal through an ultrasonic pool transmitting device in the ultrasonic rust removal pool; and S2, overturning and rust removal are carried out, specifically, the multiple universal shafts in the ultrasonic rust removal pool in the step S1 are overturned, so that movable joints of the universal shafts rotate in a reciprocating mode. According to the new energy automobile universal shaft recycling and remanufacturing repair process, circulating rotation is carried out at the top end of a bottom treatment machine box through a transmission belt, all the universal shafts are dragged through the transmission belt to sequentially pass through the ultrasonic rust removal pool, a rust removal and draining pool, an oil pool and a drying and draining pool at the top end of the bottom treatment machine box, rust removal, draining, oil immersion, drying and other processes are carried out on the surfaces of the universal shafts through the four pools, the universal shafts can be processed by multiple workers through one-time installation, and the treating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cardan shaft recycling and processing, in particular to a process for recycling, remanufacturing and repairing cardan shafts of new energy vehicles. Background technique [0002] There are many types of universal joints on new energy vehicles, such as: cross shaft type, ball cage type, ball fork type, bump type, ball pin type, ball hinge type, ball hinge plunger type, triple pin type, Triple rod type, tripod pin type, hinge rod type, etc.; the most commonly used is the cross shaft type, followed by the ball cage type. In practical applications, according to the size of the transmitted torque, it is divided into heavy duty, medium duty, light duty and small duty. It is used to connect the two shafts together. The two shafts cannot be separated when the machine is running. Only after the machine stops and the connection is disassembled can the two shafts be separated. The cardan shaft is a component that ...

AI Technical Summary

Problems solved by technology

[0006] In view of the problems in the prior art, the purpose of the present invention is to provide a new energy vehicle cardan shaft recycling and remanufacturing repair process, to solve the problem of cardan shaft in the process of derusting, mainly by manually holding sandpaper on the cardan shaft. The surface of the shaft is rubbed and derusted. The process of manual friction and derusting is time-consuming and laborious. The efficiency of derusting is low, and it is easy to miss areas. As a result, a certain area of ​​the surface of the repaired cardan shaft is not derusted, which affects the production of the cardan shaft. Technical issues of overall yield rate after batch recycling and remanufacturing
