Abstract

The invention relates to a machine tool for the running-in process of a ball and a valve seat of a ball valve. The machine tool comprises a beam, a left grinding head spindle assembly, a right grinding head spindle assembly, a left spindle feed and ball screw drive system, a right spindle feed and ball screw drive system, a ball motion control device and a valve seat clamping fixture, wherein the beam is provided with a guide rail, the left and the right grinding head spindle assemblies are arranged on the guide rail, the output ends of the spindle feed and ball screw drive systems are respectively connected with the grinding head spindle assemblies, the ball motion control device is arranged in the interspace between the left and the right grinding head spindle assemblies, and the valve seat clamping fixture is arranged on a cardan joint which is arranged on the output ends of the left and the right grinding head spindle assemblies. The invention aims at designing a machine tool which can run in and process the ball and the valve seat of the ball valve and achieve a high grinding precision and high efficiency. Compared with the prior art, the machine tool for the running-in process of the ball and the valve seat of the ball valve has the advantages that the grinding degrees and the grinding precision are controllable, the processing efficiency is high, and the cooperation between the ball and the valve seat can completely meet the hard seal requirements.

Description

technical field [0001] The invention relates to a spherical surface grinding technology, in particular to a machine tool for matching and grinding a ball and a valve seat in a ball valve. Background technique [0002] At present, there are two main methods of grinding the ball and seat in the ball valve: [0003] First, artificial grinding, using abrasive cloth for artificial surface finishing grinding, which is characterized by low efficiency; [0004] Second, use the corresponding grinding tool to grind the sphere with a single head type, which is characterized in that it is a non-matched grinding type, and the grinding accuracy and efficiency obtained in this way are lower than those of the present invention. Contents of the invention [0005] The object of the present invention is to design a machine tool for matching grinding and processing of the ball and the valve seat in the ball valve, so that it can carry out matching grinding and processing of the ball and the ...
