Welding equipment for single-end-face square pipe

Abstract

The invention discloses welding equipment for a single-end-face square pipe. The welding equipment for the single-end-face square pipe comprises a welding robot, a fixed clamping disk mechanism, a movable clamping disk mechanism, a transverse pressing mechanism, a vertical pressing mechanism, a supporting transverse beam mechanism, a vertical supporting mechanism, an internal-supporting fixture and a workpiece moving mechanism. The workpiece moving mechanism is divided into two segments of a welding segment and a feeding-and-blanking segment. The welding robot is arranged in a manner that thewelding robot is close to the welding segment. The fixed clamping disk mechanism is fixed to one end of the workpiece moving mechanism. The movable clamping disk mechanism is arranged in a middle position of the workpiece moving mechanism. The transverse pressing mechanism and the vertical pressing mechanism are arranged on the two sides of the workpiece moving mechanism. The internal-supporting fixture is arranged between the fixed clamping disk mechanism and the movable clamping disk mechanism. The supporting transverse beam mechanism is arranged in a manner that the supporting transverse beam mechanism is corresponding to a middle position of the internal-supporting fixture. The vertical supporting mechanism is arranged in a position close to the movable clamping disk mechanism. Throughthe above-mentioned arrangement, square pipes with longer length can be welded by the welding equipment for the single-end-face square pipe, deficiencies of staggered edges and lack of weld do not occur in the welding process, and the welding quality is high.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to a single-end square pipe fitting welding equipment. Background technique [0002] Due to the design requirements of single-end square pipe fittings, two long plates need to be spliced ​​and welded into a square pipe, see attached Figure 10 As shown, the workpiece has a long length of about 3.5 meters, including an end panel and two long strips. The entire pipe has two symmetrical long welds and four short welds on the edge of the end panel. Due to technical reasons, the shape of "both ends are flat and the middle is convex" appears, and the long weld seam is longer, which makes the welding process prone to misalignment and welding leakage defects, which seriously reduces the welding quality. The existing welding tooling and welding equipment cannot be fast and effective. Weld the workpiece. Contents of the invention [0003] The technical problem mainly solved by the present ...
