Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel pipe welding tools, and more particularly to an adjustable round assembly fixture for steel pipes. BACKGROUND

[0002] Pressure steel pipes are often used as the main structure of the pipeline system in water and electricity construction projects. These pressure steel pipes are generally large in diameter. In the process of machining and producing pressure steel pipes, a half-round assembly welding construction process is usually adopted, and the round assembly steel pipes are butt-welded. Since the welding seams include horizontal straight seams and butt-round seams, a round assembly fixture is needed to clamp and limit the round assembly steel pipes, so as to stably limit the round assembly steel pipes during welding, improve the efficiency of round assembly welding, and balance and fix the butt-welding seams of the steel pipes by using the round assembly fixture composed of a U-shaped plate and a connecting rib plate. The distance between the U-shaped plate and the connecting rib plate is adjusted by using a tapped round steel and a nut, so as to ensure that the welding seam deviation is controlled within the process allowable range. The construction personnel can use the round assembly fixture to reinforce the steel pipes, avoid the risk of cracks on the surface of the pressure steel pipe caused by spot welding of the pressing plate, reduce the construction labor cost, and improve the construction efficiency. However, the fixture in the above-mentioned related technology still has the following defects: the U-shaped plate in the fixture in the above-mentioned related technology is difficult to cooperate with the pressing plate to clamp different diameter steel pipes, and the welding seams of the two steel pipes are blocked after the tapped round steel is threadedly connected with the nut, which affects the steel pipe welding work. Therefore, an adjustable round assembly fixture for steel pipes is proposed. CONTENT OF THE UTILITY MODEL

[0003] 1. TECHNICAL PROBLEM TO BE SOLVED

[0004] The purpose of the present application is to provide an adjustable round assembly fixture for steel pipes, which solves the technical problem that the fixture in the above-mentioned related technology is difficult to cooperate with the pressing plate to clamp different diameter steel pipes, and the welding seams of the two steel pipes are blocked after the tapped round steel is threadedly connected with the nut, which affects the steel pipe welding work. The fixture can stably place the two Y-shaped bases on the ground when the two steel pipes are butt-welded. After the two semicircles of the steel pipes are assembled, the horizontal welding seam meets the welding process. By rotating the stud, the fixed angle clamp block and the movable angle clamp block clamp the round assembly steel pipes of different diameters, so that the welding seam forms a straight line. The distance between the Y-shaped bases can be adjusted by rotating the distance adjusting rod, and different positions of the end of the steel pipe can be clamped. The horizontal welding seam and the butt-welding seam of the two clamped steel pipes can be separated from the ground and unblocked, which is convenient for welding.
