Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, an adjustable easy-to-detach welding fixture assists stepped cylindrical product 100 to weld, including base 1 and insert 2 for assisting the welding to product 100, insert 2 quantity is four and is located base 1, is equipped with logical groove 5 in the insert 2, and four insert 2 form the welding insert, are located product 100, weld the support to product 100.

Referring to fig. 2 and 3, a base 1 is provided with a limit pin 3 and an expansion block 4, the limit pin 3 limits an insert 2, the expansion block 4 is located at the center of the base 1, the top end of the expansion block 4 is a truncated cone-shaped structure, a concave curved surface 6 is arranged at the position of the insert 2 close to the expansion block 4, when the expansion block 4 moves vertically, the insert 2 stretches inside and outside, the concave curved surfaces 6 on the four inserts 2 form an extrusion cavity, the extrusion cavity corresponds to the expansion block 4, after the expansion block 4 enters the extrusion cavity, the expansion size of the insert 2 is controlled through the extrusion cavity, after the product 100 is placed on a welding insert formed by the four inserts 2, the product 100 can be welded, in the process of welding the product 100, because the welding amount of the product 100 is large, the product 100 can shrink in the welding process, the expansion block 4 can be screwed up or unscrewed, the deformation quantity of the product 100 is controlled, when the expansion block 4 is not screwed, the insert 2 is in a free placement state, the opening size of the product 100 cannot be increased, the product 100 is convenient to weld, when the expansion block 4 is screwed, the limit pin 3 limits the insert 2 and limits the opening size of the insert 2, so that the profiling size of the tool is controlled, the welding deformation quantity of the product 100 is controlled, and the welding precision is guaranteed.
