Description

Technical Field

[0001] This utility model relates to the field of spot welding machine technology, specifically a welding clamp for a medium-frequency suspended spot welding machine. Background Technology

[0002] Suspended spot welding machines, also known as suspended welding machines, are a type of resistance welding. They involve applying pressure through electrodes after workpieces are assembled, and utilizing the resistance heat generated by current passing through the contact surface and adjacent areas of the joint to perform welding. Types include spot welding, projection welding, butt welding, and roll welding.

[0003] Currently, when spot welding parts in the workshop, due to the large batch size and the long service life of the suspended spot welding machine, a series of serious problems have been exposed in the welding clamp. The existing welding clamp adopts a one-piece molding design, which leads to significant wear on the electrode rod after long-term use. If it needs to be replaced, the whole machine needs to be replaced, which increases the cost of use and reduces its practicality. Summary of the Invention

[0006] Preferably, the external thread is adapted to the internal thread.

[0007] Preferably, the external thread is adapted to the fastening nut.

[0008] Preferably, the welding clamp body has a first connecting cavity, the electrode rod has a second connecting cavity, and the first connecting cavity and the second connecting cavity communicate with each other.

[0009] Preferably, an electrode head is fixedly installed at the end of the electrode rod away from the connecting rod, and a through hole is opened on the surface of the electrode head, and the through hole communicates with the second connecting cavity.
