Polishing fixture for conical orifice

Abstract

The invention discloses a polishing fixture for a conical orifice. The polishing fixture for the conical orifice comprises a body (1) and a locking nut (3), wherein one side of the body (1) is of a cylindrical structure, and a platform is arranged at the other side of the body (1); a groove is formed in a direction from the platform to the cylindrical structure; a circular hole (6) is formed in one end part of the body (1); one end of the circular hole (6) communicates with the groove; and the locking nut (3) is arranged on the end part of a valve body part (2) in a sleeving manner. Accordingto the polishing fixture for the conical orifice, an inner groove for placing the valve body part is formed in a body, and the valve body part is locked onto the body by the locking nut and through anexternal thread on a valve body part connector after being placed in the groove, so that the problem of difficult centering and alignment for a sealing surface is thoroughly solved, polishing for theconical orifice of a specially-shaped part is realized, and then the sealing reliability of the product is ensured.

Description

technical field [0001] The invention belongs to the technical field of orifice processing, and more specifically relates to a tapered orifice polishing tool. Background technique [0002] With the development of industry, more and more requirements for industrial products have also been improved. Many devices need to be polished during the production process to increase the gloss of the device surface and achieve the effect of beautiful appearance and fine workmanship. [0003] The valve shell parts are difficult-to-machine parts. There is an external thread interface on the side of the valve body, and a Ra0.8 cone sealing surface on the end face. Traditional polishing is manual polishing, and its polishing device generally includes a fixture, a polishing wheel and a polishing liquid tube. The fixture clamps the workpiece close to the rotating polishing wheel, and the polishing wheel is used to polish the workpiece. The polishing wheel ejects polishing fluid to cool the pol...
