Fixture for grinding outer spherical surface of spherical surface gasket

Abstract

The invention discloses a fixture for grinding the outer spherical surface of a spherical surface gasket. The spherical surface of a 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; the outer side end surface of the fixture body is fixedly connected with an end cover; the outer side end surface of the end cover is provided with a movable plate; the movable plate and the end cover are connected by a hinge pin; the hinge pin movably passes through the center hole of the movable plate to be fixedly connected to the end cover; compression springs are arranged between the movable plate and the end cover; two ends of the belt rope pass through the outer spherical surface of the fixture body to enter the inner hole of the fixture body and then pass through the end cover to be connected to two central symmetry ends of the movable plate. The fixture for the outer spherical surface 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
