Embodiment Construction

[0006] First, remove the oil stains and rust on the parts to be assembled, dry them with compressed air, and place them on the corresponding stations on the assembly line. Then perform sequential assembly: separate the half shaft gear, the half shaft gear gasket, The planetary gears, planetary gear gaskets, and planetary gear shafts are installed in the inner cavity of the differential housing. Adjust the gap between the planetary gears and the side gears. When rotating the side gears, there should be no jamming or looseness. Align the planetary gear shafts. , The small hole on the differential housing is driven into the lock pin, the two ends of the rivet lock pin are tightened, and the driven gear is pressed into the differential housing on the hydraulic press with a special tool, and the driven gear is connected. Bolts, tighten to the specified torque, use special tools to press the bearings on both sides of the differential into the two ends of the differential housing one b...

Abstract

The invention discloses an assembly line assembly technology of an automobile front differential mechanism assembly. The assembly line assembly technology is characterized by comprising the following steps: oil stain and rust on to-be-assembled parts are removed away, the to-be-assembled parts are dried by compressed air, placed on corresponding stations of an assembly line, and assembled in sequence; the to-be-assembled parts are mounted in the inner cavity of a differential mechanism shell, the clearance between a planetary gear and a half axle gear is adjusted, clamping stagnation and loosening are avoided when the half axle gear is rotated, locking pins are hit into small holes in a planetary gear shaft and the differential mechanism shell in an alignment manner, two ends of the locking pins are punched and riveted for fastening; a special tool is used for pressing a driven gear into the differential mechanism shell on a hydraulic machine, a driven gear connecting bolt is mounted and fastened to a specified torque; and the special tool is used for pressing bearings on two sides of a differential mechanism into two ends of the differential mechanism shell one by one, and the mounted differential mechanism assembly is taken down from the assembly line to be a finished product. The assembly line assembly technology is high in assembling accuracy and production efficiency, excellent in product consistency, low in cost and simple and convenient to operate, and has popularization and application value.

Description

Technical field [0001] The invention relates to a mechanical assembly method, in particular to an assembly line assembly process of an automobile front differential assembly. Background technique [0002] At present, simple tooling and manual assembly are generally used for the assembly of the differential assembly in the front axle assembly of the automobile, with low assembly accuracy, poor product consistency, high labor intensity, low production efficiency and high cost. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide an assembly line assembly process for automobile front differential assembly with high assembly accuracy, good product consistency, high production efficiency, low cost, and simple operation . [0004] In order to achieve the above-mentioned purpose of the invention, the specific process method adopted by the present invention is to first remove the oil stains and r...
