Description

Manual welding tongs for adjusting throat depth and throat width

Technical Field

The utility model relates to the technical field of manufacturing, in particular to manual soldering turret of adjusting throat depth, throat width.

Background

In the initial stage of manual electrode holder model selection, namely the no-object stage, the digital models of the electrode holder, the clamp and the workpiece are assembled together by means of digital model simulation, the welding path of the electrode holder is simulated, and then a proper electrode holder is selected. However, the method cannot truly show the special posture of the welding tongs, the labor intensity of an operator and the difficulty degree of operation. Therefore, in the physical stage, it often happens that the electrode holder selected in the simulation stage does not conform to the actual working condition, and the electrode holder is replaced again, in this case, how is the required electrode holder determined? Usually, a simple soldering turret model made of a wood board or a paper shell is used for simulating actual working conditions, and whether the size data of the soldering turret model meets the use requirements is judged. If not, the next model simulation is replaced. Repeating the steps, and determining the final welding clamp parameter specification. However, the difference in weight between the electrode holder model and the actual electrode holder is large, and the special posture of the electrode holder, the labor intensity of an operator and the difficulty degree of operation cannot be presented accurately; if the existing welding tongs are adopted for simulation, the welding tongs with various specifications and sizes are prepared according to the throat depth, the throat width, the shape and the size of the holding rod, and the operation process is time-consuming and labor-consuming. Therefore, a spot welding tongs which can truly and accurately present the special posture of the welding tongs, the labor intensity of an operator and the difficulty degree of operation and can adjust the throat depth and the throat width is needed to simulate the actual working condition.
