Grab mechanism of high-precision spot welding machine

Abstract

The invention provides a grab mechanism of a high-precision spot welding machine, and belongs to the technical field of spot welding machines. The problem of low welding quality in the prior art is solved. According to the grab mechanism of the high-precision spot welding machine, the high-precision spot welding machine comprises a work box which is provided with a welding bench, and one end of the welding bench is provided with an electrode I; and the other end of the welding bench is provide with an electrode II, and a weldment comprises a part seat and a part block welded with the part seat. The grab mechanism is characterized in that the grab mechanism is arranged above the welding bench, and comprises a base fixed to the work box, and the base is rotatably provided with a fourth screwrod as well as an erection column in parallel with the fourth screw rod; one end of the fourth screw rod is connected to a working motor which enables the fourth screw rod to rotate, and the fourth screw rod is in threaded connection with a nut III which is fixedly provided with a sliding seat II; the sliding seat II is provided with a sliding hole II, and the sliding seat II and the erection column are slidably arranged. The grab mechanism has the advantage that the welding quality is improved.
