1results about How to "Improve Spot Welding Efficiency" patented technology

The utility model discloses a kind of clamp spot welding machines, it includes rack and spot welding mechanism, the rack includes platform, the platform has the concentricity of first ring line and second ring line from inside to outside;The spot welding mechanism includes multiple first electrode and multiple second electrode, each described first electrode is spaced distribution along the first ring line, each described second electrode is spaced distribution along the second ring line, and with each described first electrode one-to-one corresponding electric connection, each described first electrode can be reciprocating along the radial direction of the first ring line synchronous movement, to with each inner layer plate of clamp one-to-one corresponding abutting or separate, each described second electrode can be reciprocating along the radial direction of the second ring line synchronous movement, to with the outer ring of clamp abutting or separate.The beneficial effects of the utility model are: the clamp spot welding machine of the utility model can simultaneously spot welding multiple inner layer plates and outer ring when spot welding the clamp of the structure, and the spot welding efficiency is higher.
