Welding device and welding method for welding seam processing for steel structure parts processing

Abstract

The present invention belongs to the technical field of weld seam treatment, in particular, a welding device and welding method for weld seam treatment for processing steel structure parts. Extension rods are fixedly connected to both ends of the side outer wall, and buffer plates are fixedly connected to the outer walls of the two extension rods. The present invention is provided with an annular track, an annular guide groove and an arc-shaped adjustment block. When grinding the weld seam through the grinding plate, the position of the grinding plate is determined according to the height of the current welding torch body, and the arc-shaped adjustment block is driven by rotating the rotating rod. Slide on the inner wall of the annular guide groove. After the sliding, adjust the No. 2 hydraulic cylinder to drive each friction plate on the adjustment block to contact the inner wall of the annular guide groove to realize the fixation of the arc-shaped adjustment block, so that the equipment can be adjusted according to the current position. The environment is adjusted to improve the scope of application and use value of the equipment.

Description

technical field [0001] The invention relates to the technical field of weld seam treatment, in particular to a welding device and a welding method for weld seam treatment for processing steel structural parts. Background technique [0002] The weld seam is the joint part formed by the weldment after welding; after the welding of the steel structure is completed, the weld seam of the welding point needs to be polished, so as to improve the aesthetics of the weld point of the polished part after welding, and at the same time , can also prolong the service life of the welded steel structure. [0003] After the existing welding device welds the steel structure, when processing the weld seam, it generally uses grinding equipment to grind the weld seam. First, the grinding equipment has a large volume and is not easy to install on the welding device. When moving to the weld seam, when the weld seam is relatively narrow, the grinding equipment cannot grind the weld seam. Secondly,...

Problems solved by technology

[0003] After the existing welding device welds the steel structure, when processing the weld seam, it generally uses grinding equipment to grind the weld seam. First, the grinding equipment has a large volume and is not easy to install on the welding device. When moving to the weld seam, when the weld seam is relatively narrow, the grinding equipment cannot grind the weld seam. Secondly, during the welding seam grinding process, the height of the grinding plate needs to be adjusted, which is generally done by adjusting the hydraulic cylinder to drive the grinding plate. In the process of lifting and lowering, when the hydraulic cylinder drives the grinding plate to squeeze the weld seam, it is easy to over-extrude. If it is over-extruded, it is easy to make the weld seam sag, resulting in problems with the welding point. It performs secondary welding, reducing the use value of the welding seam processing equipment
