Assembly process method of automobile intermediate axle assembly

Abstract

The invention relates to an assembly process method of automobile parts, in particular to an assembly process method of an automobile intermediate axle assembly. The assembly process method comprisesthe following steps that after an axle housing is cleaned, a through shaft assembly is separately arranged outside an assembly line, and then the axle housing is put on the assembly line; and then a main reduction assembly, a brake assembly, a cam shaft, an adjusting arm, a hub assembly, an air chamber and a half shaft are sequentially assembled, after the half shaft is assembled, intermediate axle assembly air tightness detection is directly conducted, and the intermediate axle assembly is taken out of the assembly line after being qualified. According to the assembly process method, the assembling postures are kept consistent from the moment that the axle housing is put on the assembly line to the moment that the intermediate axle assembly is taken out of the assembly line, 180-degree overturning does not need to be conducted on the line any more, and an axle assembly assembling supporting frame does not need to be adjusted many times; in addition, the assembling content and the assembling difficulty of an operator can be reduced, the through shaft assembly is separately arranged outside the assembly line, the large plane of the axle housing is used for supporting, the supportingis stable, and the assembly quality of the intermediate axle assembly can be ensured; and the device also has the characteristics of high assembly efficiency and convenience and quickness in operation, and is easy to popularize and apply.

Description

technical field [0001] The invention relates to an assembly process method of automobile parts, in particular to an assembly process method of an automobile mid-axle assembly. Background technique [0002] The through-shaft assembly is assembled on the middle axle assembly of the automobile, and is connected with the rear axle assembly through the transmission shaft to realize power transmission. The assembly process of the intermediate axle assembly is generally as follows: process 1, axle housing cleaning, process 2, axle housing on-line, process 3, assembling main reduction assembly, process 4, assembling brake assembly, process 5, assembling camshaft, adjusting arm , process 6, assemble the wheel hub assembly, process 7, assemble the air chamber and adjust the brake clearance, process 8, assemble the half shaft, process 9, turn over the middle axle assembly 180°, process 10, assemble the through shaft assembly, process 11 : Air-tightness testing of the mid-axle assembly...

AI Technical Summary

Problems solved by technology

[0005] (3) Affected by the adjustment of the assembly support frame and the assembly rhythm of the whole line, after the mid-axle assembly is turned over, it may not be possible to ensure that the mid-axle assembly is placed on the assembly support frame in a stable posture, which will inevitably increase the difficulty of assembly in the online assembly of the through-shaft assembly process
