Spot welding tooling of machine body of press machine and spot welding method employing spot welding tooling

Abstract

The invention relates to the field of welding process devices, and in particular relates to spot welding tooling with a simple structure and high spot welding efficiency for the machine body of a press machine and a spot welding method employing the spot welding tooling. The spot welding tooling comprises spot welding workbenches, wherein main baffle plates used for positioning two main plates of the machine body from the outer side are oppositely arranged on the left side and the right side of the spot welding workbenches; a bracket 1 and a bracket 3 which are used for positioning the two main plates of the machine body from the inner side are respectively arranged on the inner sides of the two main baffle plates; limiting stoppers are respectively arranged on the spot welding workbenches of the front end of the main baffle plate at the front end and the rear end of the main baffle plate at the rear end; adjusting bolts used for tightening the main plates of the machine body are respectively and correspondingly arranged on the main baffle plates, the bracket 1, the bracket 3 and the limiting stoppers; a bracket 2 as high as the bracket 1 is arranged on the front side of the bracket 1 side by side; the bracket 1 and the bracket 2 are used for supporting and positioning a rear drive plate; an adjusting bracket with an adjustable height is arranged on the rear drive plate; a bracket 4 as high as the bracket 3 is arranged on the front side of the bracket 3 side by side; the bracket 3 and the bracket 4 are used for supporting a workbench sliding plate; a clutch overlapping bracket is also arranged on each spot welding workbench.

Description

technical field

[0001] The invention relates to the field of welding process devices, in particular to a spot welding tool for a press fuselage and a spot welding method using the tool. Background technique

[0002] The fuselage is a basic part of the press. In order to facilitate the customization of the size and parameters of the press, the fuselage of most presses adopts a steel plate welded structure. The whole welded fuselage can be split into several steel plates of different thickness and shape, such as figure 1 As mentioned above, it mainly includes two fuselage main boards parallel to the left and right. The rear side between the main boards of the fuselage is respectively fixed with a rear transmission plate, a rear support plate and a front support plate from bottom to top, and a top rib is vertically fixed between the rear support plate and the front support plate, and one of the bottom of the rear transmission plate The inner side of the fuselage main board is...
