An outer wall of the sleeve 3 is fixedly sleeved with a turntable 4. The turntable 4 is horizontally arranged. Upper and lower ends of the sleeve 3 extend outside the turntable 4. A plurality of through holes 15 are provided on the turntable 4 and are distributed at equal intervals in a circular shape. An inner diameter of the through hole 15 is larger than an outer diameter of the valve sphere. The through hole 15 is close to an outer edge of the turntable 4. A clamping block 16 is fixedly connected to an upper side wall of the turntable 4 on one side of the through hole 15. The clamping block 16 is located at the outer edge of the turntable 4, and the clamping block 16 and the through hole 15 on one side thereof are in the same radial direction of the turntable 4. An upper end of the sleeve 3 is fixedly connected with a support plate 7 located above the turntable 4. The support plate 7 is horizontally arranged and separated from the turntable 4.

[0020] A pushing and clamping mechanism is arranged on the support plate 7. The pushing and clamping mechanism includes a cylinder 11 fixed on the support plate 7. The cylinder 11 is horizontally arranged and a driving end thereof faces outward along the radial direction of the turntable 4. A driving end of the cylinder 11 is fixed with a clamping block 12 that matches the clamping block 16. The clamping block 16 and the clamping block 12 are used to jointly clamp and fix the valve sphere.

[0021] A plurality of support rods 8 are symmetrically arranged on the base 1. Upper ends of the support rods 8 are jointly fixedly connected with a backing plate 9 located below the turntable 4. The backing plate 9 is annularly arranged and provided with a notch. The notch disconnects the backing plate 9. An upper side wall of the backing plate 9 is smoothly arranged. A plurality of through holes 10 are provided on the backing plate 9 and are distributed at equal intervals. An inner diameter of the through hole 10 is larger than a diameter of a processing hole of the valve sphere and smaller than an outer diameter of the valve sphere.

Place the valve sphere to be processed in the first through hole 5 on the turntable 4 and support it through the backing plate 9. Start the motor 13, and the turntable 4 drives the sphere to move. When the sphere is at the position pointed by the driving end of the cylinder 11, start the cylinder 11. The cylinder 11 drives the second clamping block 12 to move towards the corresponding first clamping block 6, and clamp and fix the sphere at this position through the first clamping block 6 and the second clamping block 12, and then implement drilling processing. After the processing is completed, the motor 13 rotates again, and the first through hole 5 drives the processed sphere to move and drop materials from the notch of the backing plate 9. The staff only needs to replenish materials in the first through hole 5 in time, without the need for manual clamping and unloading operations on the sphere, reducing the labor intensity of workers and also improving the automation degree of sphere clamping.
