Description

Technical Field

[0001] The utility model relates to the technical field of welding processing, in particular to a positioning mechanism for automatic welding equipment. Background Art

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Welding achieves the purpose of joining through the following three ways. Welding technology is mainly used on metal base materials. Commonly used methods include arc welding, argon arc welding, CO2 shielded welding, oxygen-acetylene welding, laser welding, electroslag pressure welding, etc. Non-metallic materials such as plastics can also be welded. There are more than 40 metal welding methods, which are mainly divided into three categories: fusion welding, pressure welding and brazing.

[0003] In the Chinese patent with publication number CN220217329U, an automatic welding positioning device is disclosed, including a workbench, which is driven by the output shaft of the first driving motor to rotate the bidirectional threaded rod, and the two sets of sliders cannot rotate under the cooperation of the second limit block and the slide groove, and can only move in a straight line, so that the two sets of connecting blocks and the positioning table move synchronously relative to each other, and the positions of the two sets of clamped steel plates are adjusted to make the ends of the two sets of steel plates fit together, and the piston rod of the second electric push rod is extended and retracted to drive the mounting frame to move downward, thereby driving the welding gun to move downward, and the output shaft of the second driving motor is rotated to drive the threaded rod to rotate, and the moving block cannot rotate under the cooperation of the first limit block and the limit groove, thereby driving the welding gun to move, and the two sets of steel plates are welded, so that the welding operation does not need to be manually held by the steel plate for welding, and the situation that the two steel plates are easily offset during welding is avoided, which improves the accuracy of welding to a certain extent and improves the welding efficiency.

[0004] The above scheme has the following shortcomings: in actual use, this scheme only presses the top of the steel plate through the first electric push rod and the pressure plate, and does not limit the two sides of the steel plate, resulting in the steel plate being easily shaken and shifted in position during welding, thereby reducing the welding accuracy of the steel plate and affecting the welding effect of the steel plate.
