Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe surfacing welding, and particularly relates to an anti-displacement tooling for steel pipe surfacing welding. Background Technique

[0002] As an economical and rapid process method for material surface modification, surfacing welding is more and more widely used in the manufacturing and repair of parts in various industrial departments. Surfacing welding on the inner wall of a steel pipe can improve the strength, corrosion resistance and other properties of the steel pipe, so as to meet the application of the steel pipe in various environments.

[0003] Chinese Patent with the authorization announcement number CN204954137U discloses an anti-displacement tooling for surfacing welding on the inner wall of a steel pipe. It is installed by the cooperation of the V-shaped groove on the driving wheel and the V-shaped boss of the positioning ring. The steel pipe will not generate any front-back displacement during the welding process. By sleeving the positioning ring on the appropriate position of the steel pipe and then tightening the bolts, the steel pipe can be locked. The above device has the following drawbacks: Since there is no biting relationship between the V-shaped groove on the driving wheel and the V-shaped boss of the positioning ring, when the speed of the driving wheel is relatively high, there may be a slipping phenomenon between the driving wheel and the positioning ring, thus affecting the surfacing welding effect of the steel pipe; moreover, since each bolt needs to be operated separately, the central axis of the steel pipe and the central axis of the positioning ring cannot coincide, thus affecting the surfacing welding quality of the steel pipe. Therefore, it is urgent to study an anti-displacement tooling for steel pipe surfacing welding to solve the above problems. Summary of the Utility Model
