Example Embodiment

[0014] The accompanying drawings show the technical solutions and embodiments of the present invention. The relevant details and working principles of the embodiments will be further described below in conjunction with the accompanying drawings.

[0015] Such as Figure 1-2 As shown, the spherical gasket A ground in the present invention has an inner spherical surface, an outer spherical surface and a central inner hole, and the outer spherical surface is provided with a narrow groove A1 along the diameter direction of the spherical gasket.

[0016] Such as Figure 3-6 As shown, the outer spherical surface grinding fixture of the spherical gasket of the present invention includes a clamp body 6 having an outer spherical surface 4 and a flange 1 fixed to the clamp body 6. The outer spherical surface 4 radians of the clamp body 6 and the inner surface of the spherical gasket A The curvature of the spherical surface is the same. Six positioning pins 3 are evenly distributed on the top...

Abstract

The invention discloses a fixture for grinding outer spherical surfaces of spherical washers. The outer spherical surface of each ground spherical washer is provided with a narrow groove along the diameter direction. The fixture is characterized in that the fixture comprises a fixture body, a plurality of positioning pins are circumferentially and evenly distributed on the top of an outer spherical surface of the fixture body, and the top of each positioning pin is provided with a transverse groove. During grinding operation, the spherical washers arranged on the outer spherical surface of the fixture body are bound by a rope, the rope passes through the narrow grooves and the transverse grooves, the outer end surface of the fixture body is fixedly connected with an end cover, a rotating plate is arranged on the outer end surface of the end cover, the rotating plate is connected with the end cover through a locking screw, the locking screw movably passes through the central hole of the rotating plate and is then screwed in the end cover, and both ends of the rope pass through the outer spherical surface of the fixture to enter the hole of the fixture body, and then pass through the end cover to connect with the rotating plate. The fixture which is used for the grinding of the outer spherical surfaces of the spherical washers can rapidly clamp and reliably fix the spherical washers, and increases working efficiency.

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 ...
