Drive shaft assembly assembling method

Abstract

The invention relates to a drive shaft assembly assembling method. The drive shaft assembly assembling method includes of step 1, assembling of a subassembly A by mounting a universal joint on a flange yoke by an extruder and workbench equipment, and mounting a universal joint yoke on the universal joint; step 2, assembling of a subassembly B by mounting a universal joint on a flange yoke by the extruder and the workbench equipment, and mounting a spline shaft yoke and a splined hub subassembly or a slide yoke and a rear shaft head subassembly on the universal joint; step 3, assembling the subassembly A, the subassembly B and a shaft tube into a drive shaft assembly by means of extrusion by the extruder and a universal fixture; step 4, straightening and welding the drive shaft assembly by a special welding machine and the universal fixture; step 5, subjecting the drive shaft assembly to dynamic balance by a balance machine and the universal fixture. By the drive shaft assembly assembling method, assembling precision and product quality of the drive shaft assembly can be improved, processing errors of parts are eliminated, labor efficiency is improved, production cycle is shortened and production cost and labor intensity are lowered.

Description

technical field [0001] The invention relates to a transmission shaft assembly method, in particular to a transmission shaft assembly assembly method. Background technique [0002] As people have higher and higher requirements for the humanization of automobile design and the comfort of automobile passengers, the requirements for the dynamic balance accuracy and residual unbalance value of the transmission shaft assembly are also higher and higher. Before the new drive shaft assembly assembly process was used, the original assembly process used to assemble extrusion, alignment, and welding three major parts (that is, universal joint fork, shaft tube, shaft head or spline) Hub), then assemble the flange fork, universal joint, sliding fork (shaft fork), and finally carry out the dynamic balance test. The main disadvantages are: the residual unbalance value is too large, the design accuracy is not easy to guarantee, and the production efficiency is low; The process cycle is lon...

Problems solved by technology

Before the new drive shaft assembly assembly process was used, the original assembly process used to assemble extrusion, straightening, and welding three major parts (that is, universal joint fork, shaft tube, shaft head or spline) Hub), then assemble the flange fork, universal joint, sliding fork (shaft fork), and finally carry out the dynamic balance test. The main disadvantages are: the residual unbalance value is too large, the design accuracy is not easy to guarantee, and the production efficiency is low; The process cycle is long, time-consuming, labor-intensive, and labor-intensive, which cannot meet the actual production needs; moreover, the dynamic balance and actual loading state are not simulated during extrusion assembly and alignment welding, and the positioning references are inconsistent, resulting in error accumulation and difficult dynamic balance quality.
