Light car drive axle assembly assembling product line

Abstract

The invention provides a light automobile driving axle assembly production line, comprising a differential sub-assembly assembly line, a main reducer-assembly assembly line, a main reducer assembly running test platform and a soundproof platform, a half-axle and brake sub-assembly assembly line and a driving axle assembly whole assembly line; the main reducer-assembly assembly line is an assembly line with a closed ring which is formed by the circular connection of two sets of assembly clamp travelling pallet swap vehicles and a lifting machine; the lower end of the differential sub-assembly assembly line is connected with the upper end of the main reducer-assembly assembly line; the driving axle assembly whole assembly line is a subsequent assembly line which is assembled with the half-axle and brake sub-assembly connection after the differential sub-assembly is assembled with the main reducer assembly; the connection of line shift operation is carried out by a circular air transport vehicle. In the technical proposal of the invention, all the assembly lines have compact structure in the arrangement, smooth object-flow and operation shift and high assembly operation efficiency and creates beneficial conditions for the matching and butt-assembly of the drive gears and driven gears in the drive gear pair and the driven gear pair of the main reducer assembly and for gaining online detection.

Description

technical field [0001] The application of the present invention relates to a light-duty vehicle drive axle assembly assembly line. Background technique [0002] The drive axle assembly of light-duty vehicles is a key component in the transmission system of light-duty vehicles. The main structure includes differential sub-assembly, final reducer assembly, half-shaft and brake sub-assembly and axle housing assembly. At present, the assembly of the drive axle assembly of light vehicles still adopts the production form of independent wiring based on the assembly line of the differential subassembly and the assembly line of the main reducer assembly, equipped with general tooling equipment, testing tools and primary instruments , assisting off-line detection; each assembly line is completed by a synchronous rigid conveyor line for moving between assembly processes, and its fixtures are fixedly installed on the rigid conveyor line to move, and only have two operating states of ful...

Problems solved by technology

At present, the assembly of light vehicle drive axle assembly still adopts the production form of independent wiring based on the assembly line of differential subassembly and the assembly line of main reducer assembly, equipped with general tooling equipment, testing tools and primary instruments , assisting off-line detection; each assembly line is completed by a synchronous rigid conveyor line for moving between assembly processes, and its fixtures are fixed and installed on the rigid conveyor line to move, and only have two operating states of full-line movement or full-line stop, which cannot meet the requirements of each assembly line. Requirements for relocation of different steps in the process or testing and measuring processes; in the operation of each assembly process, it is necessary to rely more on the experience of the operator, because too many human factors are involved, often unqualified products are reworked, and the assembly efficiency is low In addition, the decentralized form of the assembly line in the prior art leads to the paired driving gear and the driven gear in the driving and passive gear pairs can only be moved to the differential sub-assembly assembly line and the main reducer assembly assembly line for combined assembly. , because the production rhythms of the two assembly lines are often out of sync, it is easy to have the technical problem that the driving gear and the passive gear assembled in the same main reducer assembly are mixed and cannot obtain the best meshing accuracy in the contact area

Furthermore, the assembly line uses primary instruments for off-line measurement, which can only perform partial qualitative measurement of the key quality characteristics of the product, and cannot achieve the technical purpose of comprehensive quantitative measurement

To sum up, the current conventional light vehicle drive axle assembly assembly method is difficult to fully guarantee the requirements for improving product quality, assembly quality, and production efficiency.
