A precision pulley bracket welding assembly machine

Abstract

The invention relates to a precision pulley bracket welding and assembling machine. The precision pulley bracket welding and assembling machine comprises a rack, a clamping workbench, a workbench driving assembly, a workpiece fixture assembly, an argon arc welding assembly and a polishing assembly. The rack comprises a feeding and discharging station, an argon arc welding station and a polishing station. The clamping workbench is arranged on the rack and makes contact with the feeding and discharging station, the argon arc welding station and the polishing station at the same time. The workbench driving assembly is arranged below the clamping workbench and drives the clamping workbench to rotate horizontally. The workpiece fixture assembly is arranged on the clamping workbench and used for installing and fixing a pulley shaft and a pulley bracket which need to be welded and assembled. The argon arc welding assembly is arranged in the argon arc welding station, and argon arc welding is conducted on the pulley shaft and the pulley bracket on the workpiece fixture assembly. The polishing assembly is arranged in the polishing station, and the welding position of the pulley shaft and the pulley bracket is polished. Compared with the prior art, the assembling process, the welding process and the polishing process can be effectively completed automatically, the production efficiency is high, and the surface quality is good.

Description

technical field [0001] The invention relates to welding and assembling equipment, in particular to a precision pulley bracket welding and assembling machine. Background technique [0002] When welding the pulley bracket, the pulley shaft needs to be inserted into the sheet metal hole. The end surface of the shaft is 0.1mm lower than the sheet metal surface. The two workpieces are welded by argon arc welding. And there must be no traces of welding burns on the sheet metal plane. After welding to form a precision pulley bracket, the connection strength is required to be high, and the perpendicularity between the axis and the sheet metal plane is 0.05mm. During the welding process, arc start and end, welding arc distance, welding speed and current stability will all affect the processing results. [0003] The method in the prior art is to fix the shaft and the sheet metal parts with welding fixtures, weld them manually, take them out from the fixtures after welding, put them i...

AI Technical Summary

Problems solved by technology

The processing efficiency of the prior art method is very low, and it is difficult to control the height of the weld scar and the uniformity of the weld scar, which often results in excessive local accumulation of weld scars and over-melting, which makes the workpiece scrapped or subsequent processing is difficult. This technical problem hinders the improvement of efficiency and The bottleneck of stable quality
