Abstract

The invention relates to a rotating spherical surface numerically controlled accurate grinding equipment with high hardness. The equipment comprises a bed body part, a main spindle box part, a wheel stand rotating table part, a tail seat part and a grinding wheel. The main spindle box part and the tail seat part are fixed on the bed body through a bolt; the wheel stand rotating table part is supported on a circular arc guide rail and a circular ring guide rail, a winding and fixed axle moves to and fro through a worm rod and a sector worm wheel under the driving of an actuating motor; the actuating motor drives a wheel stand slide seat to do direct feed motion on the guide rail on the wheel stand rotating table through a feed screw nut pair; the grinding wheel composed of a grinding wheel disc and a grinding wheel block is directly connected with an electric principal axis through a connecting shaft, thereby the propose that the grinding wheel with diameter is used for grinding a rotating spherical surface work piece with high hardness and different diameters though the high speed rotation movement of the grinding wheel, the rotation movement of the rotating spherical surface work piece, the feed movement of the grinding wheel stand and the reciprocating motion of the grinding wheel stand.

Description

technical field [0001] The invention relates to a numerical control grinding machine in the technical field of machine tools, in particular to a high-hardness rotary spherical surface numerical control precision grinding machine. Background technique [0002] High-hardness and high-precision balls are key components in high-temperature, high-pressure, and wear-resistant ball valves. Because the working conditions of this type of ball valve are very harsh, in order to improve its high temperature resistance and wear resistance, the ball surface of the ball valve is usually sprayed with high hardness materials such as WC and Ni60 with high wear resistance, which gives the surface Precision machining poses great difficulties. On the other hand, since this kind of ball valve generally works in a high temperature and high pressure environment, the sealing requirements are also quite high. In this case, a hard sealing method is often adopted. In this sealing method, the shape acc...
