Welding fixture and welding cart

Abstract

The invention discloses a welding fixture. The welding fixture comprises a first clamping mechanism, a second clamping mechanism and a connecting mechanism; the first clamping mechanism comprises a first fixing arm and a first pressing arm; the second clamping mechanism comprises a second fixing arm and a second pressing arm; and the connecting mechanism comprises a first fixing block and a secondfixing block, the first fixing block is provided with a connecting plate, and the second fixing block is provided with a connecting hole connected with the connecting plate in a buckling mode. One end of a workpiece is compressed on the first fixing arm through the first pressing arm, the other end of the workpiece is compressed on the second fixing arm through the second pressing arm, the two ends of the workpiece are quickly clamped and driven to be connected in a folding butt-joint mode, rolling and sizing of a metal plate are achieved through buckling connection of the connecting plate and the connecting hole, in-place folding butt-joint connection is achieved, and the edge rolling uniformity of the metal plate workpiece is guaranteed. The invention further provides a welding cart based on the welding fixture.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a welding fixture and a welding cart. Background technique [0002] In the production process, straight cylindrical, arc-shaped or other shaped metal workpieces made of sheet metal are widely used, among which, straight cylindrical workpieces that are bent and welded into straight cylindrical shapes are widely used parts in the industry, and exist in Boiler, shipbuilding, automobile, metal structure and other machinery manufacturing industries. [0003] In the prior art, large-scale rolling equipment is required for rolling thicker metal sheets, and then welding is performed. However, it is obviously not suitable for rolling thinner metal plates or metal sheets, which has a complex structure and low investment. Large and costly rolling equipment. Therefore, most of the manufacturers who produce thin metal straight tube workpieces can only roll and weld by manual o...

Problems solved by technology

[0003] In the prior art, large-scale rolling equipment is required for rolling thicker metal sheets, and then welding is performed. However, it is obviously not suitable for rolling thinner metal plates or metal sheets, which has a complex structure and low investment. Large and costly rolling equipment

Therefore, most manufacturers who produce thin metal straight workpieces can only roll and weld manually.

However, the manual operation method not only has low efficiency of metal sheet rolling and high labor intensity, but also has the problem of low roundness of the metal straight cylinder after rolling and difficulty in aligning the connection positions at both ends of the metal sheet, which affects the forming of the metal straight cylinder. , thereby greatly reducing the quality of the finished product and the production efficiency of the subsequent stage of the process
