Problems solved by technology

[0003] The length of the boom barrel is relatively long. During the welding process of the boom barrel, only some simple process supports are used to fix the relevant dimensions of the product and welded. The welding time is long, the processing accuracy is poor, the production efficiency is low, and the product quality is not good. Stable, high requirements on workers' welding skills, high scrap rate, not suitable for mass production

Abstract

The invention discloses a bi-directional pressing device applicable to a lap welding tooling for a suspension arm cylinder. The bi-directional pressing device comprises a first pressing device used for applying pressing force to two half cylinder bodies forming the suspension arm cylinder in the first direction, and a second pressing device used for applying pressing force to the half cylinder bodies in the second direction, wherein the first pressing device and the second pressing device are connected; and the first direction is perpendicular to the second direction. According to the bi-directional pressing device applicable to the lap welding tooling for the suspension arm cylinder, during manufacturing of the suspension arm cylinder, the two half cylinder bodies can be accurately located, clamped and fixed, the processing accuracy and production efficiency of the suspension arm cylinder are improved, the stabilization for the quality of a suspension arm cylinder product is facilitated, the ejection rate is low, the requirement on skills of welding workers is reduced a lot, the labor intensity is reduced, and the bi-directional pressing device is applicable to large-batch production.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery processing equipment, in particular, the invention relates to a bidirectional pressing device suitable for lap welding tooling of a boom tube. Background technique [0002] Construction machinery such as hoisting machinery in the prior art all has a boom. The boom is one of the important components of the hoisting machinery and is used to lift heavy objects to a certain height. The safety, stability and reliability of the boom are The key element for judging the performance and quality of hoisting machinery, and the boom is mainly composed of multiple boom tubes, and the boom tube is a component welded by two half cylinders with a hollow interior. [0003] The length of the boom barrel is relatively long, and during the welding process of the boom barrel, only some simple process supports are used to fix the relevant dimensions of the product and welded. The welding time is long, the...
