Rotary shaft welding fixture, workbench and rotary shaft automatic welding system

Abstract

The invention discloses a rotating shaft welding jig, a rotating shaft welding worktable and an automatic rotating shaft welding system. The rotating shaft welding jig comprises a rotating shaft clamp and a component fixing device, wherein the rotating shaft clamp is used for clamping a rotating shaft, and the component fixing device is used for fixing a rotating shaft component which needs to be welded to the rotating shaft. The rotating shaft clamp comprises a rotating shaft supporting and rotating mechanism and a rotating shaft supporting and clamping mechanism, wherein the rotating shaft supporting and rotating mechanism and the rotating shaft supporting and clamping mechanism are used for clamping the two ends of the rotating shaft respectively. The component fixing device is arranged between the rotating shaft supporting and rotating mechanism and the rotating shaft supporting and clamping mechanism and comprises a rotating shaft component clamping part and a clamping driving part. The rotating shaft component clamping part comprises a plurality of bases which are arranged on a base plate side by side, wherein the bases include at least one fixed locating base and a plurality of sliding bases. The clamping driving part is connected with the rotating shaft component clamping part and can drive the sliding bases to slide towards the locating base so that the adjacent bases can clamp and loosen the rotating shaft component. The rotating shaft welding jig can clamp the rotating shaft and the rotating shaft component at a time.

Description

technical field [0001] The invention relates to the field of processing and manufacturing of various workpieces based on a rotating shaft, in particular to a rotating shaft welding fixture, a workbench and an automatic rotating shaft welding system.

AI Technical Summary

Problems solved by technology

At present, the processing method of the shaft usually adopts low-efficiency forging, casting, convenient manual gas shielded welding equipment and technology, brazing, and efficient robot semi-automatic gas shielded welding. Because of its simple and easy operation, it is widely used in coal mines and rail vehicles. , automobiles, low-voltage electrical appliances and other industries have played a great role, but in many occasions, it is difficult to obtain good welding results with this equipment and technology, and its shortcomings are mainly manifested in high labor intensity, high energy consumption, and long cycles. , low efficiency; it is easy to cause many weld joints, uneven welding, large splashes, and poor product consistency; some parts will produce undercutting and local severe ablation; and cracks, slag inclusions, and Defects such as incomplete penetration and virtual welding
