Problems solved by technology

[0002] In the existing technology, the process of welding first and then assembling is adopted, which makes the cooling time of the welded parts longer, and the universal joint is assembled before the workpiece is completely cooled, which affects the flexibility of rotation, and the shape and position of the parts at both ends are not affected by the beating of the assembly. Considering the tolerance, the runout of the sub-assembly meets the requirements of the drawing, but the runout of the assembly is often out of tolerance after assembly, and the production cycle is long

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] As shown in the figure, the overall press-fit welding process of the heavy-duty transmission shaft, the steps are as follows:

[0019] (1) Universal joint assembly;

[0020] (2) Assembly press-fitting: including welding fork small assembly and shaft fork small assembly;

[0021] (3) The assembly is relatively straight and welded;

[0022] (4) Runout detection after welding, straighter;

[0023] (5) Dynamic balance detection.

[0024] According to the production forecast order, the welding fork small assembly and the shaft fork small assembly are assembled online first. When the product is switched, only the clamps at both ends need to be replaced to achieve fast switching and improve production efficiency. The overall alignment welding is adopted to calculate all the shape and position tolerances of the parts into the runout of the drive shaft assembly, so as to...

Abstract

The invention relates to an integral press-fitting and welding process for a heavy-duty transmission shaft. The integral press-fitting and welding process comprises the steps of 1, universal joint assembling; 2, assembly press fitting; 3, assembly straightening and welding; 4, post-welding run-out detecting and straightening; and 5, dynamic balance detecting. The process has the beneficial effectsthat personnel of a production line are reduced, the length of the production line is shortened, and assembling of universal joint assemblies can be completed in advance according to a forecast order; and in the producing procedure, for the same specification, just travel adjustment needs to be carried out according to the lengths of different shaft pipes, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to a welding process, in particular to an integral press-fit welding process of a heavy transmission shaft. Background technique [0002] In the existing technology, the process of welding first and then assembling is adopted, which makes the cooling time of the welded parts longer, and the universal joint is assembled before the workpiece is completely cooled, which affects the flexibility of rotation, and the shape and position of the parts at both ends are not affected by the beating of the assembly. Considering the tolerance, the runout of the sub-assembly meets the requirements of the drawing, but the runout of the assembly is often out of tolerance after assembly, and the production cycle is long. Contents of the invention [0003] The present invention solves the above-mentioned shortcomings of the prior art, and provides a more efficient overall press-fit welding process for heavy-duty transmission shafts. [0004] The ...
