Tool device capable of controlling sheet welding gap

Abstract

The invention provides a tool device capable of controlling a sheet welding gap. The device comprises a fixing base, quick pressing heads, first bolts and second bolts; a groove is formed in the middle of the fixing base, and a plurality of gas spraying holes are uniformly formed in the bottom of the groove in the extending direction of the groove; first fastening screw holes and first connectingscrew holes are formed in the two sides of the groove, and the bolts are in screw joint in the first connecting screw holes; the quick pressing heads are oppositely arranged and fixed on the two sidesof the groove in the extending direction of the groove correspondingly, each fast pressing head comprises a support, a pressing arm assembly and a pressing head, the pressing arm assemblies are pivoted to the tops of the supports, the supports are fixed to the fixing base, the pressing heads are fixed at the ends, adjacent to the groove, of the pressing arm assemblies, the second bolts are in screw joint in the first fastening screw holes, and the pressing heads can be inserted into the first fastening screw holes. According to the tool device capable of controlling the sheet welding gap, theconsistency of gaps in the welding process can be simply and effectively controlled, and the problems of gap change and clamping failure caused by the fact that a sheet is deformed are prevented.

Description

technical field [0001] The invention relates to the technical field of welding tooling fixtures, in particular to a tooling device capable of controlling the welding gap of thin plates. Background technique [0002] At present, on the basis of CMT (Cold Metal Transfer Welding Technology) technology, further research and development, combining AC MIG / MAG welding technology into CMT technology, can realize AC CMT process, which is what we call CMT Advance (AC Change Polarity Cold Metal Transfer Technology). ) process. At this time, unlike the traditional MIG / MAG welding process, the welding process, the polarity of the welding wire is no longer always positive (PE), but in the process of continuous conversion of positive and negative polarities. Can achieve CMT transition. The heat input of CMTAdvance is smaller than that of CMT, and the arc force impact on the sheet is also small, so this mode has good bridging ability. In welding production, bridging capabilities are used...
