Plate workpiece welding fixture

Abstract

The invention relates to a welding fixture for plate workpieces. The load-bearing device is installed on the base. The locking button is divided into upper and lower parts. The upper part is installed on the pressing positioning block, and the lower part is installed on the load-bearing device. The clamping area placed between the load-bearing fixture and the pressing positioning block is positioned and clamped by the locking button; the locking button includes a front fixed end, a rectangular locking lever, a wrench, a rear fixed end, a spring and a connecting rod, and the front The fixed end is installed on the pressing positioning block, the rear fixed end is installed on the load-bearing device, the wrench is hinged on the rear fixed end through the pin shaft, the rectangular locking rod is installed on the connecting rod with holes at both ends, and the spring sleeve Between the two open ends of the rectangular locking rod and the connecting rod, the connecting rod passes through the wrench with holes to drive the rectangular locking rod to move with the wrench. It can quickly and accurately position and clamp plate workpieces, and clamp plate workpieces with different thicknesses.

Description

technical field [0001] The invention relates to a welding fixture for plate workpieces, which belongs to the technical field of fixtures. Background technique [0002] Plate workpiece welding fixture is a special process device for assembling and welding stamped and formed plate parts. It is the key equipment that directly affects output and quality. Reasonable design of assembly welding fixture is the key to greatly reducing the workpiece processing cycle, improving production efficiency and reducing costs. fundamental way. Most of the welding fixtures are specially designed for the assembly and welding process of certain welding assemblies. Do. The design of the welding fixture is an important part of the production preparation work and the main task of the welding production process design.

Problems solved by technology

[0003] Traditional plate parts welding fixtures generally use simple two pressure plates and four compression bolts. It often takes a long time to loosen and tighten the bolts when clamping and positioning plate workpieces, and the workpiece also needs to be positioned multiple times. The effect is poor, the production efficiency is low, and the positioning fixture will cause indentations on the surface of the workpiece due to the over-tightening of the bolts, which will damage the processed or to-be-processed surface of the workpiece and reduce the processing accuracy of the workpiece
