Fixture for grinding spherical surface gasket

Abstract

The invention discloses a fixture for a grinding spherical surface gasket. The outer spherical surface of a grinded spherical surface gasket is provided with a narrow groove along a diameter direction. The fixture is characterized in that the fixture comprises a fixture body, wherein the top circumstance of the outer spherical surface of the fixture body is evenly provided with a plurality of locating pins; the top of each locating pin is provided with a lateral groove; during grinding work, the spherical surface gaskets arranged on the outer spherical surface of the fixture body are tightened by a belt rope; the belt rope passes through the narrow groove and the lateral grooves; one end of the belt rope is fixedly arranged on the fixture body, and the other end of the belt rope is connected with the outer circle of a rotation ring; the rotation ring is rotatably arranged on a shaft lever; the shaft lever is fixedly connected with a flange plate; the outer side of the rotation ring is provided with a fixed ring; the fixed ring is fixedly arranged on the shaft lever; a torsion spring is arranged between the rotation ring and the fixed ring; one end of the torsion spring is inserted into the rotation ring, and the other end of the torsion spring is inserted into the fixed ring. The fixture is used for the grinding processing of the outer spherical surface of the spherical surface gasket, the quick clamping and the reliable fixing of the spherical surface gasket can be realized, and working efficiency is improved.

Description

【Technical field】 [0001] The invention relates to a grinding fixture used for grinding the outer spherical surface of a 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 ...

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
