A method for controlling coaxiality between parts and components

Abstract

The invention discloses a method for controlling the coaxiality between components. (1) Machining process: 1.1 Use the 2 ΦA holes on the reamer bracket; 1.2 Finish the 2 ΦA holes on the bracket; 1.3 Use the first coaxial mandrel to measure the coaxiality between the 2 ΦA holes on the bracket (2) Welding process: 2.1 Put the open retaining ring and the bearing into the bearing hole of the rocker arm to form the rocker arm assembly; 2.2 Use the second coaxial mandrel to wear the rocker arm assembly and the adjustment piece formed in step 2.1 2.3 Insert the second coaxial mandrel into the left hole of the mounting hole on the fixture. The invention has the characteristics of wide adaptability and simple and easy operation, can improve the qualified rate of coaxiality, can improve production efficiency, can ensure that when each part rotates around the transmission shaft, the rotation flexibility is good, and the performance index of the whole product can be improved. The beneficial effect of being enhanced.

Description

technical field [0001] The invention relates to a method for controlling the coaxiality, in particular to a method for controlling the coaxiality between components. Background technique [0002] In the process of assembly and use of parts and components, there is a need to meet the requirements of rotational flexibility after assembly of parts and components. Since the parts and components are assembled by welding parts such as machined parts and bearings, it involves machining, welding, Assembly and other links, and the batch is large. [0003] The company has failed to effectively solve the problem of poor product performance due to poor rotation flexibility of the component for many years, and users have repeatedly reported that the product is faulty. [0004] Therefore, through the research of product design drawings, our company's engineers found that the reason for the poor rotation flexibility of the component and the failure of the product with multiple feedbacks w...

[0003] The company has failed to effectively solve the problem of poor product performance caused by the poor rotation flexibility of the component for many years, and has been repeatedly reported by users that the product is faulty

[0004] Therefore, through the research of product design drawings, our company's engineers found that the reason for the poor rotation flexibility of the component and the failure of the product with multiple feedbacks was that the product design drawings did not stipulate the requirements for rotation flexibility or coaxiality; During the welding process, the requirements for the coaxiality between the porous parts are not identified and not effectively controlled. If the coaxiality between the parts is not well controlled during the machining process and the welding process, the rocker arm will rotate after assembling the drive shaft inflexibility problem
