Problems solved by technology

[0004] However, there are some defects in the above-mentioned grinding machine. For example, the left and right grinding heads need to be used together, which makes the equipment more complicated. This will affect the processing accuracy, resulting in low precision of the ground ball and deviation in roundness, resulting in water leakage after the valve core and seat of the ball valve are matched.

Abstract

The invention provides a ball grinding machine, belongs to the mechanical technical field and solves the technical problems that in the prior art, the ball grinding precision is not high, deviation isgenerated on roundness and the like. According to the technical scheme, the ball grinding machine comprises a rack. The rack is rotatably connected to a grinding head for grinding a target ball or amounting disc for fixing an external grinding cover; a supporting rod is also arranged above the rack; the outer end of the supporting end is fixedly connected to an output shaft of a driving source II and the driving source II can drive the supporting rod to rotate. The ball grinding machine provided by the invention can grind the outer spherical surface of the ball all around without dead angles. The ball and the grinding equipment are more easily aligned during processing, and the position needs not to be adjusted precisely.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a ball grinder. Background technique [0002] The ball mainly includes the spool of the ball valve. The spool of the ball valve generally has a central hole in the middle for assembly in the valve body of the ball valve. The spherical surface of the spool is in contact with the valve seat, and the function of opening and closing the ball valve is played by turning the spool. . The spherical surface of the valve core requires high precision in manufacturing, and it needs to be ground after rough machining to achieve higher precision and adaptability to the valve seat. In addition, the ball can also include other parts similar to this valve core structure but applied in other fields. [0003] The existing spherical grinding machine, such as a spherical automatic grinding machine disclosed in patent CN201420469091.9, includes a frame, a main shaft mechanism, and a grinding head mec...
