Embodiment Construction

[0033] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0034] The present embodiment comprises a kind of sphere, comprises the sphere body 18 that metal is made, and sphere body 18 is provided with a center hole 19 along arbitrary axis, and the two ends of center hole 19 run through sphere body 18, and sphere body 18 is in the two ends of center hole 19. There is an annular plane 22 perpendicular to the axis of the central hole 19 at the end edge, the central axis of the annular plane 22 coincides with the central axis of the central hole 19, and the annular plane 22 surrounds the central hole 19 along the end edge line of the central hole 19 A keyway 20 is provided on the outer spherical surface, the keyway 20 is located between two annular planes 22, and the outer spherical s...

Abstract

The invention provides a sphere and a machining method thereof, and belongs to the technical field of machines. According to the sphere and the machining method thereof, the technical problems that inthe prior art, the grinding precision of the sphere is not high, and deviation of roundness exists are solved. According to the technical scheme, the sphere comprises a sphere body made of metal, a central hole is formed in the sphere body along any axis, and the two ends of the central hole penetrate through the sphere body. The machining method of the sphere comprises the steps that the lower end of a grinding sleeve is fixed to a mounting disc, the inner end of a supporting rod is inserted in the central hole of the sphere body, and the supporting rod and the sphere body are detachably fixed; and the sphere body is placed on the grinding sleeve, a first driving source is started to drive the grinding sleeve to rotate in the direction of the vertical axis, a second driving source is driven to drive the supporting rod to rotate in the direction of the horizontal axis, the supporting rod drives the sphere body to rotate synchronously, thus grinding movement with the perpendicularly staggered movement track is generated between the sphere body and the grinding sleeve, grinding is conducted till the outer spherical surface of the sphere body reaches the preset precision requirement,then grinding is stopped, and the sphere body is taken out and discharged.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a sphere and a processing method thereof. 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 mechani...
