Description

Technical Field

[0001] The utility model relates to the technical field of workshop processing tooling equipment, in particular to a transferable tooling for a processing center. Background Art

[0002] Flat welding and butt welding are the welding methods for connecting flanges and pipes. Flat welding flanges only need single-sided welding and do not need to weld the inner port of the pipe and flange. Butt welding flanges require double-sided welding of flanges for welding installation. Therefore, flat welding flanges are generally used for low and medium pressure pipelines, and butt welding flanges are used for medium and high pressure pipelines. Butt welding flanges are generally at least PN2.5MPa. Butt welding is used to reduce stress concentration. Generally, butt welding flanges are mostly neck flanges, also called nipple flanges.

[0003] During welding, the pipe and the flange need to be positioned concentrically, and some pipes have large diameters, making it difficult to obtain effective fixation. For example, the patent application number CN201310615038.5, the patent name of which is a pipe flange welding positioning device, discloses a pipe flange welding positioning device, which includes a fixed seat, a first positioning mechanism installed on the fixed seat, a push-pull block installed on the fixed seat and abutting against the first positioning mechanism, and a push-pull driving mechanism matched with the push-pull block. The fixed seat is provided with a base and a central axis extending from the base along the axial direction of the pipe, and the first positioning mechanism is sleeved on the central axis.

A mutually matching inclined surface is provided between the first floating wedge and the push-pull block. The first positioning mechanism is arranged such that when the push-pull driving mechanism pushes and pulls the push-pull block along the axial direction, the first floating wedge moves radially inward or outward along the central axis under the action of the push-pull block and the first elastic element.
