Description

Technical Field

[0001] The utility model relates to a positioning mechanism for a steel pipe compression welding device. Background Art

[0002] A steel pipe refers to a steel material with a hollow cross-section and a length much larger than its diameter. According to its shape, it can be divided into round, square or special-shaped steel pipes, etc. During the processing of the steel pipe, the steel plate must first be bent by a bending device to make the steel plate present a tubular semi-finished pipe fitting after bending, and then the edges on both sides of the semi-finished pipe fitting are welded. During the welding process, the edges on both sides of the semi-finished pipe fitting tend to open due to elasticity, and external pressure is required to keep the edges on both sides of the semi-finished pipe fitting close together before it can be welded and fixed. In addition, when the steel pipe is used on a steel pipe tower, the specifications of the steel pipe are often large, and it is difficult to apply external pressure. For this reason, the prior art "CN202021614493.5 ", provides a steel pipe welding fixture clamping platform, which includes a vertical hydraulic rod, a pipe pressing column and a horizontal clamping seat. The three cooperate to position the semi-finished pipe fittings, so that the edges of the semi-finished pipe fittings on both sides are fitted, which is convenient for welding. However, after the supporting platform of the prior art positions the semi-finished pipe fittings, the semi-finished pipe fittings cannot be moved, and the staff or welding equipment needs to move relative to the semi-finished pipe fittings. In addition, the specifications of the steel pipes used in the iron tower field are large, which results in the staff needing to use auxiliary components to weld, and the auxiliary components need to be moved. If welding equipment is used, the welding equipment needs to be displaced a large distance as a whole, which is difficult to do. The position of the semi-finished pipe fittings is often adjusted during the welding process, which causes many inconveniences. Utility Model Content
