Problems solved by technology

[0004] When the spherical surface of the existing ball valve is ground, the trunnion is generally clamped by a fixture, and the fixture and the ball core are driven by the motor to rotate, and the grinding head is attached to the grinding work. However, this grinding device only It can process a ball core, and the grinding head must be replaced immediately when the grinding head is worn out. During the replacement period, processing cannot be performed, and the position accuracy of the replaced grinding head needs to be corrected, which is very troublesome to use and low in efficiency.

Abstract

The invention discloses a spherical surface grinding device for ball valve cores and particularly relates to the field of ball valve element machining. The spherical surface grinding device for the ball valve cores comprises a worktable, a rotating table is arranged at the top of the worktable, a multi-ball-core clamping mechanism is arranged at the top of the rotating table, outer grinding platesare arranged on the two sides of the multi-ball-core clamping mechanism respectively, the two outer grinding plates are driven through a reciprocating mechanism to do reciprocating linear movement and are used for grinding the spherical surfaces of ball cores fixed by the multi-ball-core clamping mechanism, tooth grooves are formed in the outer wall of the rotating table, and a driving gear engaged with the tooth grooves is arranged on the rear side of the rotating table. The spherical surface grinding device can grind multiple ball cores at the same time, and the working efficiency is greatly improved; besides, when the contact faces of the outer grinding plates and the ball cores are worn, position offset replacement of multiple ball core clamps can be achieved simply by driving the rotating table through the driving gear, and the grinding faces of the outer grinding plates and the ball cores are replaced; and the grinding device is very convenient to use, adjustment is quick, and the machining efficiency and the precision of the ball cores are not influenced.

Description

technical field [0001] The embodiment of the present invention relates to the field of ball valve core processing, in particular to a spherical surface grinding device for a ball valve core. Background technique [0002] The ball valve is one of the most widely used valves. Its working principle is the same as that of the plug valve. It is opened and closed by rotating the valve core, but it is lighter than the plug valve and relatively small in size. It can be made into a large-diameter ball valve. The ball valve has reliable sealing, simple structure and convenient maintenance. The sealing surface and the ball are often in a closed state, which is not easy to be eroded by the medium, so it is widely used in petroleum, chemical, metallurgical and other industries. [0003] A ball valve generally includes a valve body, a valve seat, and a ball placed in the seat. The ball generally includes two parallel and symmetrical end faces. The distance between the two end faces is sma...
