AI Technical Summary

Technical Problem

Although the existing welded pipe welding fixture can achieve the fixation and rotation of the welded pipe, it requires manual alignment before welding and cannot achieve automatic limiting and movable docking, which affects the welding process efficiency.

Method used

A positioning structure for pipe welding is designed, which includes a positioning mechanism, a load-rotating structure and a limiting structure. The servo motor drives a bidirectional screw and an electric push rod to achieve precise horizontal and vertical positioning of the welded pipe, and the load-rotating wheel and the limiting structure ensure the stability of the welded pipe during the welding process.

Benefits of technology

It realizes automatic limiting and mobile docking of welded pipes, improves welding efficiency, ensures welding quality and stability, and reduces welding defects caused by inaccurate positioning.

Abstract

The utility model discloses an alignment structure for welding of welded pipes, which comprises a processing table, an alignment mechanism is arranged at the top of the processing table, two welded pipes needing to be welded are respectively placed on a carrying and rotating structure and a fixing sleeve which are arranged on two sides of the top of the processing table through the alignment mechanism, and the carrying and rotating structure is matched with the fixing sleeve to preliminarily support the welded pipes. Then, a limiting structure at the bottom of the support descends to slightly limit the welded pipe in the vertical direction so as to ensure that the welded pipes on the two sides are stably placed, then electric push rods on the front side and the rear side of a fixing sleeve are started to push a fixed sliding sleeve at the telescopic end to move in the direction of the welded pipe till the fixed sliding sleeve makes contact with the welded pipe and slightly clamps the welded pipe; then, a servo motor is started to drive a two-way screw rod to rotate, and due to the fact that the directions of threads on the two sides of the surface of the two-way screw rod are opposite, the two sliding blocks in threaded connection with the two-way screw rod can move in the sliding grooves in the same direction or in the opposite directions.
