Outer spherical surface grinding fixture for spherical gasket

Abstract

The invention discloses an outer spherical surface grinding fixture for a spherical gasket. The outer spherical surface of the spherical surface gasket is provided with a narrow groove. The outer spherical surface grinding fixture is characterized by comprising a fixture body, wherein a plurality of positioning pins are uniformly distributed on the top circumference of the outer spherical surface of the fixture body; the tops of the positioning pins are provided with transverse grooves. During grinding work, the spherical gasket distributed on the outer spherical surface of the fixture body is tied with a rope, and the rope passes through the narrow groove and the transverse grooves; the outer side end face of the fixture body is fixedly connected with an end cover; the outer side end face of the end cover is provided with a rotary plate and a check block; the rotary plate and the end cover are connected with each other through a pin shaft; the pin shaft movably passes through a center hole of the rotary plate, and is fixedly connected to the end cover; the outer side end face of the rotary plate is provided with a spring; the check block is fixed on the end cover; the two ends of the rope pass through the outer spherical surface of the fixture body to enter the inner hole of the fixture body, and pass through the end cover to be connected to the rotary plate. The outer spherical surface grinding fixture is applied to grinding of the outer spherical surface of the spherical gasket, rapid clamping and reliable fixing of the spherical gasket can be realized, and the working efficiency is increased.

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
