Description

Technical Field

[0001] The utility model relates to the technical field of spot welding machines, in particular to a positioning structure for spot welding machines. Background Art

[0002] Spot welding machine is a mechanical equipment that adopts the principle of double-sided double-point overcurrent welding. When working, two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode through the other electrode, an instantaneous heat weld is formed at the two contact resistance points, and the welding current instantly flows from the other electrode along the two workpieces to this electrode to form a loop, and will not damage the internal structure of the workpiece being welded.

[0003] In the process of using a traditional spot welding machine, the workpiece is often held by hand for spot welding, which not only poses certain risks, but also may not accurately position the welding point. For example, the patent CN219254456U of the Chinese utility model disclosure specification discloses a positioning structure for a desktop spot welding machine, including a workbench, the top of which is fixedly connected to a top frame, and two positioning grooves are arranged between two positioning blocks, so that the workpiece can be positioned and placed by being placed inside the positioning groove, and the mutual displacement clamping of the positioning blocks driven by the sliding of the sliding blocks in the sliding grooves by the telescopic power of the two second hydraulic rods, so that the two sides of the workpiece in the positioning grooves can be firmly fixed, so that the welding point can accurately and firmly correspond to the welding of the electrode rod, and the coordinated telescopic movement of the two second hydraulic rods during the period enables the workpiece to flexibly adjust the lateral position of the welding point left and right. In summary, the problem that the traditional spot welding machine is often held by hand for spot welding during use, which not only poses certain risks, but also may not accurately position the welding point, is solved.

[0004] The existing positioning structure for spot welding machines does not have the function of positioning special-shaped products. For example, the above-mentioned patent can position the welding points, but the clamping model is relatively fixed. In daily use, it is impossible to position products with special shapes such as diamonds and ellipses, which limits the scope of application of the positioning structure for spot welding machines.
