A clamp welding integrated welding tongs

Abstract

The invention discloses a clamping and welding integrated welding tongs, which includes a mechanism frame, a welding mechanism, a clamping mechanism and a driving cylinder. The welding mechanism and the clamping mechanism connected in linkage are connected to the mechanism frame. The welding mechanism includes two welding swing arms that can be relatively rotated to approach or move away from each other. The upper and inner sides of the welding swing arms are correspondingly provided with electrode caps, and the two electrode caps are detachable against the two sides of the sheet metal. The clamping mechanism includes two clamping swing arms that can be rotated relatively close to or far away from each other. The upper part of the clamping swing arm is provided with clamping positioning blocks correspondingly on the inner side, and the two clamping positioning blocks are releasably offset against the two sides of the sheet metal. . The clamping and welding integrated welding tongs of the present invention has a simple structure, clamps first and then welds, not only eliminates the gap, but also determines the position of the electrode cap and the sheet metal, effectively controls the welding deformation, reduces the breakdown phenomenon during welding, and improves the welding quality .

Description

technical field [0001] The invention relates to a welding tongs, in particular to a clamp welding integrated welding tongs used in the automobile manufacturing industry. Background technique [0002] At present, the traditional general automatic welding tongs, such as figure 1 As shown, it includes: a fixed support 1, a welding cylinder 2, a cylinder joint connecting rod 3, and two electrodes 4,5. In order to determine that the electrodes 4 and 5 are in place, an induction signal switch 7 is also provided, and the cylinder joint connecting rod 3 connects the welding cylinder with the induction signal switch 7, etc., and the two electrodes 4 and 5 rotate around the electrode rotation point 6 and approach for welding. Or away from the end solder. However, the disadvantage of such automatic welding tongs is that it has many disadvantages, such as a large installation space, a long distance between the welding point and the clamping point, there may be gaps between the sheet m...

Problems solved by technology

[0003] The present invention is completed in order to solve the deficiencies in the prior art. The purpose of the present invention is to provide a simple structure, which makes the clamping mechanism and the welding mechanism linked, first clamps and then welds, and not only eliminates the need for welding during the clamping process. The gap between the sheet metal parts also determines the position of the electrode cap and the sheet metal part, which can effectively control the welding deformation, reduce the breakdown phenomenon during welding, and improve the welding quality.
