Welding electrode clamp holder for sealing gasket spot welding and measurement and compensation method of clamp holder

Abstract

The invention relates to a welding electrode clamp holder for sealing gasket spot welding. The welding electrode clamp holder comprises a servo motor, a ball lead screw nut pair is arranged at the output end of the servo motor, and a push plate is fixedly connected to the front end of the ball lead screw nut pair; linear bearings are fixedly arranged at the upper and lower ends of the push plate and matched with cylinder shafts, a motor fixing plate is arranged at the other ends of the cylinder shafts, and linear guide rail pairs are fixedly arranged at the other side of the motor fixing plate; first mounting blocks are further fixedly installed at the upper and lower ends of the push plate, connection rods are hinged to the first mounting blocks, and the other end of each connection rod is hinged to a second mounting block; the second mounting blocks are limited to slide up and down in the linear guide rail pairs, welding bases are further fixedly connected to the second mounting blocks, and welding electrodes are arranged on the welding bases. The welding electrode clamp holder has the following advantages that the grasping force can be precisely adjusted, for sealing gaskets ofdifferent number combinations, by setting parameters, the welding intensity of the clamp holder can be accurately adjusted, and the appearance quality after product spot welding is guaranteed.

Description

technical field [0001] The invention belongs to the field of sealing gaskets, and in particular relates to a sealing gasket spot welding electrode holder and a measurement and compensation method thereof. Background technique [0002] The quality of automobile engine sealing performance has become one of the important symbols to measure the quality of automobiles. The existing sealing gaskets are all clamped by the cylinder clamping device. When doing it manually, there are often many pieces and few pieces. Sometimes it is difficult to distinguish the naked eye when they stick together. In the end, the inspector often finds that the product has multiple pieces. In the case of a small number of pieces, although it was found, it had to be scrapped because it could not be repaired. [0003] Moreover, the metal gaskets are relatively soft. If multiple sheets are welded together, a force is first required to hold them tightly together, and then a current is applied to achieve a ...
