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. Guaranteed; no lead time

Embodiment 1

[0014] Embodiment 1: Concrete process steps are as follows:

[0015] The first step: Part A assembly (called Part A assembly): install the universal joint on the flange fork with extrusion machine and workbench equipment, and then install the universal joint fork on the universal joint;

[0016] Step 2: Part B assembly (called Part B assembly): install the universal joint on the flange fork with extrusion machine and workbench equipment, and then install the spline shaft fork and spline hub on the universal joint ( or sliding fork and rear axle head) sub-assembly;

[0017] Step 3: Use an extruder and a universal fixture to extrude and assemble part A, part B and the shaft tube into a drive shaft assembly;

[0018] Step 4: Align and weld the transmission shaft assembly with a special welding machine and a general fixture;

[0019] Step 5: Use a dynamic balancing machine and a universal fixture to dynamically balance the drive shaft assembly.

[0020] The comparison between t...

Abstract

The invention relates to an assembling process of a drive shaft assembly. The process comprises the following steps: the first step: the assembling of part A: an extruder and a working platform device are adopted to arrange a universal joint on a flange fork and a universal joint fork on the universal joint; the second step: the assembling of part B: an extruder and a working platform device are adopted to arrange a universal joint on a flange fork and a spline shaft fork and a spline hub sub-assembly or a sliding fork and a rear shaft head sub-assembly on the universal joint; the third step: an extruder and a universal clip extrudes and assembles components of part A, components of part B and a shaft tube into a drive shaft assembly; the fourth step: a welding machine and a universal clip are adopted for alignment and welding of the drive shaft assembly; and the fifth step: a dynamic balancer and a universal clip are adopted for the dynamic balance of the drive shaft assembly. Therefore, the invention can increase the assembling precision and product quality of the drive shaft assembly, eliminates the part processing error, improves the labor efficiency, shortens the production period and decreases the production cost and labor intensity.

Description

Technical field: [0001] The invention relates to an assembly process of a transmission shaft assembly which can improve the assembly precision and product quality of the transmission shaft assembly, eliminate part processing errors, improve labor efficiency, and reduce production cost and labor intensity. 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, straightening, and welding three major parts (ie 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 a...
