Clamping mechanism of cross beam welding fixture

Abstract

The invention provides a clamping mechanism of a cross beam welding fixture. The clamping mechanism comprises a base, wherein a fixture block is arranged on the left side of the upper end of the base;the right side of the upper end of the base is connected with a rotating arm through a shaft pin; an overturning cylinder is arranged on the right side of the base; the left side of the overturning cylinder is connected with the base through a shaft pin; the upper end of the overturning cylinder is connected with the right end of the rotating arm through a shaft pin; the left end of the rotatingarm is connected with a mounting plate; a first cylinder is arranged on the left side of the mounting plate; the lower end of the first cylinder is connected with a first pressing arm through a shaftpin; a second cylinder is arranged in the middle of the mounting plate; the lower end of the second cylinder is connected with a first pressing point; a third cylinder and a fourth cylinder are arranged on the right side of the mounting plate; the third cylinder is arranged on the front side of the fourth cylinder; the lower end of the third cylinder is connected with a second pressing arm througha shaft pin; and the lower end of the fourth cylinder is connected with a second pressing point. The clamping mechanism is scientific and reasonable in structural design, simple in structure, convenient to use, accurate in positioning, reliable in clamping and convenient to use.

Description

technical field [0001] The invention relates to the field of welding fixtures, in particular to a clamping mechanism for a beam welding fixture. Background technique [0002] The use of welding fixtures suitable for the product structure in modern welding production plays a very important role in improving product quality, reducing labor intensity of workers, and accelerating welding production to achieve mechanization and automation. The quality of the welding seam cannot be guaranteed during welding by simple self-made positioning plates or manual positioning, and it is easy to loosen during welding, resulting in welding deviation, resulting in high rejection rate, so it becomes very important to solve this problem. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a clamping mechanism for a beam welding fixture, which is respectively fixed by the first pressing arm and the first pressing point, the second pressing arm and the second pr...

[0002] The use of welding fixtures adapted to the product structure in modern welding production plays a very important role in improving product quality, reducing labor intensity of workers, and accelerating welding production to achieve mechanization and automation. Or through a simple self-made positioning plate or manual positioning, the quality of the weld cannot be guaranteed during welding, and looseness is likely to occur during welding, resulting in welding deviation, resulting in a high scrap rate, so it is very important to solve this problem
