As preferably, the projection welding bottom electrode comprises cylindric bottom electrode body, and one of the bottom electrode body is embedded with the bottom electrode head, and the other end of bottom electrode body is connected with the connecting plate that through hole is set.The bottom electrode body is connected with transformer by cable.Connecting plate is connected with welding bench by screw.The projection welding bottom electrode is easy for installation, adjusts flexibly.A projection welding bottom electrode has a cable to link to each other with transformer, and weldingvoltage can guarantee.
As preferably, welding bench is provided with substrate, and substrate is provided with several through holes; Convenient welding table top dismounting projection welding bottom electrode and fixed mount, also convenient projection welding bottom electrode and the fixed mount installation site adjusted.
As preferably, the soldering turret frame is provided with and can makes the projection welding top electrode with respect to welding bench relative translation structure; Make things convenient for left and right adjusting projection welding top electrode position.
As preferably, the soldering turret frame is provided with and can makes the projection welding top electrode with respect to the relative rotational structure of welding bench; Regulate projection welding top electrode position before and after convenient.
As preferably, the soldering turret frame is provided with hinge, and hinge is connected with soldering turret; Make things convenient for up-down adjustment projection welding top electrode position.
Compared with prior art, the utility model beneficial effect is: the projection welding top electrode separates with the projection welding bottom electrode, and the welding work pieces area is not subjected to projection welder rack construction size restrictions, and the projection welder scope of application is wide.The convenient welding that realizes a plurality of nuts, these class smallclothes of bolt on the large tracts of land workpiece of one platform convex welding machine reduces workpiece and clamps number of times, alleviates labor strength; Do not need to increase nutplate, alleviate tare, save production cost.
