A kind of seamless steel pipe welding equipment and its welding method

Abstract

The invention discloses a seamless steel pipe welding equipment and a welding method thereof, comprising a support seat, a positioning plate is fixedly installed on both sides of the top of the support seat, and a fixed sleeve is fixedly installed inside the positioning plate, so that The internal thread of the fixed sleeve is connected with an adjustment rod, one end of the adjustment rod is rotated and installed with a clamping block, the other end of the adjustment rod extends to the outside of the fixed sleeve, and the front side of the middle end of the top of the support seat is fixedly installed with a fixed plate. In the present invention, one end of the steel pipe can be clamped and fixed by setting the adjusting rod and the clamping block, and the clamping part inside the clamping block is set in an arc shape which coincides with the shape of the steel pipe, which can ensure the stability after clamping, and at the same time Two clamping sleeves are set on the side of the support seat, which can fix the front end of the steel pipe after clamping. Not only the clamping effect is good, but also to ensure that there will be no shaking during welding, and the clamping distance can be adjusted according to the size of the steel pipe , Improve welding quality.

Description

Technical field [0001] The present invention relates to the field of steel pipe welding technology, and is specifically a welding apparatus for seamless steel tubes and a welding method thereof. Background technique [0002] Seamless steel tubes can be used to make a variety of equipment parts, often need to weld the tube wall, such as supporting the steering housing of the steering wheel in the automobile steering system, and the steering housing is one of the core components in the automobile steering system, which needs to be When the seamless steel pipe connection is performed, the conventional welding method is to position the seamless steel pipe in the drilling machine, clamping, using the welding equipment for welding, but this conventional welding method is during processing due to steel pipe during processing The clamp is unstable, and the steel pipe will slightly rotate during the welding process, which will not only cause the welding quality to decrease, but the weldin...

AI Technical Summary

Problems solved by technology

[0002] Seamless steel pipes can be used to manufacture a variety of equipment parts. Welding of the pipe wall is often required during processing, such as the steering housing under the steering wheel in the automobile steering system. The steering housing is one of the core components of the automobile steering system. Weld the joints of seamless steel pipes during processing. The traditional welding method is to position and clamp the seamless steel pipes on the drilling machine with a clamp and then use welding equipment for welding operations. However, this traditional welding method is due to the The clamping is unstable, and the steel pipe will rotate slightly during the welding process, which will not only reduce the welding quality, but also cause burrs to be left on the inner wall of the seamless steel pipe, which will affect the processing quality of the steel pipe
