Plate type workpiece welding clamp

Abstract

The invention relates to a plate type workpiece welding clamp. A bearing device is arranged on a pedestal; a locking button is divided into upper and lower parts; the upper part is arranged on a press positioning block; the lower part is arranged on the bearing device; the upper and lower parts are both positioned on a vertical plane; a to-be-machined workpiece is arranged in a clamping region between a bearing clamp and the press positioning block to be positioned and clamped by the locking button; the locking button comprises a front fixed end, a rectangular locking rod, a wrench, a rear fixed end, a spring and a connecting rod; the front fixed end is arranged on the press positioning block; the rear fixed end is arranged on the bearing device; the wrench is hinged with the rear fixed end through a pin shaft; the rectangular locking rod is arranged on the connecting rod with holes in the two ends; the spring sleeves between two open ends of the rectangular locking rod and the connecting rod; the connecting rod penetrates through the wrench with a hole to drive the rectangular locking rod to move with the wrench. A plate type workpiece can be quickly and accurately positioned and clamped to clamp plate type workpieces of 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
