Description

Technical Field

[0001] The utility model relates to the technical field of spot welding machines, in particular to a spot welding machine which is convenient for lifting a plate to be welded. Background Art

[0002] Spot welding machine is a kind of mechanical equipment, which 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 to the other electrode, an instantaneous heat welding 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] According to the description of a spot welding machine disclosed in the patent website (authorization announcement number: CN 213764421 U), "This application discloses a spot welding machine, which relates to the technical field of welding equipment and reduces the labor burden of workers when welding plates. It includes a machine body, and the machine body is provided with an upper welding rod and a lower welding rod connected to a power source. A lower bracket is provided on the side of the machine body, and the lower welding rod is vertically fixed to the lower bracket. The upper welding rod is arranged directly above the lower welding rod. A support plate for placing the plate is horizontally slidably connected to the lower bracket, and two abutment bars that slide in a direction perpendicular to the long strip hole are slidably connected to the support plate. The workpiece is installed between the two abutment bars, and the two abutment bars are parallel to the long strip groove. The support plate and the abutment bar are provided with a locking assembly for fixing the abutment bar, and the abutment bar is provided with a locking mechanism for fixing the workpiece on the support plate. This application fixes the plate on the support plate, and the welding of the plate can be completed by sliding the support plate. The operation is convenient, the labor burden of the staff is effectively reduced, and the welding accuracy of the plate is improved."

[0004] In view of the above description, the applicant believes that there are the following problems:
