Auxiliary tool for welding of traction rod

Abstract

The invention provides an auxiliary tool for welding of a traction rod. The auxiliary tool comprises a bottom plate. Two shaft positioning assemblies are symmetrically arranged on the two sides of thebottom of the bottom plate. A jacking assembly is arranged on the top of the bottom plate. A jacking screw is arranged on the jacking assembly. A first quick clamping device is arranged on the lowerportion of the jacking assembly. A second quick clamping device is arranged in the middle of the bottom plate. Two brackets are symmetrically arranged on the two sides of the lower part of the secondquick clamping device. A baffle is arranged beside the bracket at one end. Positioning pin holes are formed in each shaft positioning assembly. The auxiliary tool has the beneficial effects that the traction rod is clamped at the position of the baffle and the brackets, then the traction rod is positioned and fixed jointly through the shaft positioning assemblies and the jacking assembly, and finally the positioned position is fixed by the two quick clamping devices, so that the coaxiality of a front shaft is quickly positioned and accurately determined; and meanwhile, due to the fastening ofworkpieces by the baffle and other positioning devices, the welding precision is improved, and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a welding auxiliary tool for a draw bar. Background technique [0002] The drawbar is an important connecting piece connecting the bogie and the car body, and realizes the function of the drawbar driving the vehicle with a load. It plays the role of transmitting traction and braking force. The quality of the drawbar assembly is directly related to the mechanical performance of the vehicle. Therefore, the processing accuracy of the drawbar directly affects the straightness of the car during driving. Therefore, high processing dimensional accuracy is required, and the product shape, position and coaxiality of the drawbar require high precision. At present, the commonly used welding method is to manually control the workpiece speed and manually weld. Due to the special shape of the drawbar, the workpiece is bulky, there are many positions to be processed...

AI Technical Summary

Problems solved by technology

Due to the special shape of the drawbar, the workpiece is bulky, there are many positions to be processed, and the strict process requirements make it difficult to clamp the workpiece. Using manual placement for welding will easily cause the welding position to shift, and the accuracy cannot be guaranteed, and the entire welding The welding quality of the process depends on the welding experience of the operator, and has high requirements for welding operators

It is difficult to manually control the welding position, and the accuracy of the coaxiality of the front axle cannot be guaranteed. The quality of welding formation is greatly affected by human factors, resulting in long processing time, low pass rate, and unguaranteed construction period.
