HORN MOVING MECHANISM FOR SPOT WELDER AND SPOT WELDER WITH IT

摘要

PROBLEM TO BE SOLVED: To improve a conventional spot welder in which it is so difficult, and it takes much labor and time to make a horn move just a desired distance. SOLUTION: The spot welder has a rotational driving portion installed in a clamping block and a driven portion installed in the horns, when the rotational driving portion arranged at the side or down side of the horns in the clamping blocks, is rotated by rotating the rotational shaft, the driven portion is driven by the driving portions, the horn is moved in the axial direction, and by rotating the rotational shaft in reverse, the horn moves in the reverse direction.
