Spherical washer and fixture for grinding spherical washers

Abstract

The invention discloses a spherical washer and a fixture for grinding spherical washers. An outer spherical surface of the spherical washer is provided with a narrow groove along the diameter direction; the fixture comprises a fixture body with an outer spherical surface, and a plurality of positioning pins are circumferentially and evenly distributed on the top of the outer spherical surface of the fixture body. The fixture is characterized in that the top of each positioning pin is provided with a transverse groove, and the transverse grooves are arranged in the top circumferential direction of the outer spherical surface. During grinding operation, the spherical washers arranged on the outer spherical surface of the fixture body are bound by a rope, the rope surrounds the outer spherical surface of the fixture body for a circle, the rope passes through the narrow grooves and the transverse grooves, one end of the rope is fixed on the fixture body, the other end of the rope is connected with the outer circle of a rotating ring, the rotating ring is screwed on a screw, a locknut is arranged on the outer end surface of the rotating ring, and the locknut is also screwed on the screw. The spherical washer provided by the invention can be rapidly clamped and reliably fixed on the fixture disclosed by the invention, consequently, the spherical washers can be conveniently ground by machining equipment, and working efficiency is increased.

Description

【Technical field】 [0001] The invention relates to a spherical gasket and a fixture for grinding the spherical gasket. 【Background technique】 [0002] A spherical gasket is a gasket with an inner and outer spherical surface. The key to a spherical gasket lies in its spherical surface accuracy and smoothness. For quite a few spherical gaskets, the outer spherical surface has high requirements for accuracy and smoothness, and the outer spherical surface must be ground. Processing to achieve the required accuracy and finish. The technical solution provided by the patent number 200810121605.0 and the patent name "Jig for Grinding Spherical Gaskets" solves the above technical problems, but the disadvantage is that it can only be used for spherical gaskets made of iron materials. For spherical gaskets made of copper materials, there is no way to use the above-mentioned patented technology to carry out grinding processing. Later, the applicant also adopted some methods to solve the...

Problems solved by technology

The technical solution provided by the patent number 200810121605.0 and the patent name "Jig for Grinding Spherical Gaskets" solves the above technical problems, but the disadvantage is that it can only be used for spherical gaskets made of iron materials. For spherical gaskets made of copper materials, there is no way to use the above-mentioned patented technology to carry out grinding processing. Later, the applicant also adopted some methods to solve the above-mentioned technical problems, and also applied for related patents. Manually clamping the spherical gaskets one by one is slow and obviously cannot meet the requirements of mass production. What is more serious is that there are problems that the spherical gaskets cannot be reliably fixed on the fixture and the clamping is not reliable. Spherical gaskets are easy to come off during grinding
