Variable-angle automatic spot welding device moving along with profiling track

Abstract

The invention discloses a variable-angle automatic spot welding device moving along with a profiling track, which is used for realizing the automatic welding on an arc profile workpiece. The variable-angle automatic spot welding device moving along with the profiling track comprises a base, workpiece locating mechanisms, a welding machine, a welding machine space angle adjusting mechanism, a welding machine rotating mechanism, a welding machine movable driving mechanism and a profiling track seat, wherein the welding machine is fixedly arranged on the upper surface of the welding machine space angle adjusting mechanism through a welding machine fixing seat, the welding machine space angle adjusting mechanism is in assembling with the welding machine rotating mechanism, the welding machine rotating mechanism is arranged between the welding machine space angle adjusting mechanism and the welding machine movable driving mechanism, the welding machine movable driving mechanism and the profiling track seat are positioned on the base, and the left side and the right side on the upper surface of the base are symmetrically provided with the workpiece locating mechanisms. According to the variable-angle automatic spot welding device moving along with the profiling track, disclosed by the invention, the automation degree is high, the operation is simple, the labor intensity of an operator can be reduced, the working efficiency and the welding quality can be increased, the variable-angle automatic spot welding device has the characteristics similar to those of a mechanical arm, the input cost is lower, and the maintenance is more convenient.

Description

technical field [0001] The invention relates to an automatic spot welding device, in particular to an automatic spot welding device suitable for workpieces with curved and curved contours, and belongs to the field of welding technology. Background technique [0002] At present, in the welding process of the automobile body, small welding workpieces with arc-curved outlines (such as the rear section assembly of the front door and window frame) are generally welded and assembled by manual spot welding. The specific working process is as follows: the operator first places the main part with a certain arc shape (such as the front door and window frame) on the welding tool, then places the parts to be welded on the main part, and then starts the control valve to make the fixture clamp the workpiece. The operator takes the welding tongs to start welding, and after the welding is finished, the workpiece is taken out from the welding tool. Since the entire welding process is comple...

AI Technical Summary

Problems solved by technology

Since the entire welding process is completed manually, not only the labor intensity of the operators is high, but the work efficiency is low, and the welding quality is not easy to guarantee, which cannot meet the requirements of production consistency.
