Clamp for grinding spherical gaskets

Abstract

The invention discloses a clamp for grinding spherical gaskets. A narrow groove is formed in an outer spherical surface of each ground spherical gasket along the diameter direction; the clamp is characterized by comprising a clamp body, wherein a plurality of positioning pins are uniformly arranged on the circumference of the outer spherical surface of the clamp body; transverse grooves are formed in the tops of the positioning pins; in a grinding work process, the spherical gaskets arrayed on the outer spherical surface of the clamp body are tightened by a belt rope; the belt rope passes through the narrow grooves and the transverse grooves; one end of the belt rope is fixed on the clamp body and the other end of the belt rope penetrates through the outer spherical surface of the clamp body to enter an inner hole of the clamp body, and then is connected with a lower swinging end of a swinging crank; the swinging crank is rotationally arranged on a shaft rod and the shaft rod is fixedly connected with a flange plate; an upper swinging end of the swinging crank is connected with one end of a tension spring and the other end of the tension spring is connected with an inner hole wall of the clamp body. The clamp for grinding the spherical gaskets is used for grinding and machining the outer spherical surfaces of the spherical gaskets so that the rapid clamping and reliable fixation of the spherical gaskets can be realized and the 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
