During use, control the first motor 452 to start, drive the driving shaft 451 and the gear 45 to drive the driven gear ring 44 and the driving ring 43 to rotate. Cooperating with the planar thread convex movably clamped in the planar thread groove, drive the plurality of positioning sliders 42 to move towards each other. On the contrary, control the first motor 452 to start, drive the driving shaft 451 and the gear 45 to drive the driven gear ring 44 and the driving ring 43 to rotate in the reverse direction. Cooperating with the planar thread convex movably clamped in the planar thread groove, drive the plurality of positioning sliders 42 to move away from each other, and flexibly adjust the distance between the plurality of positioning sliders 42 to adapt to the subsequent support, clamping and positioning of spheres 5 with different aperture sizes;

[0026] The structure of the top support member 402 is the same as that of the bottom support member 401. The top support member 402 and the bottom support member 401 are symmetrically distributed. By providing the bottom support member 401 and the top support member 402 with the same structure, it is convenient to support, clamp and position the lower half and the upper half of the sphere 5 subsequently.

Then, the sphere 5 is placed between a plurality of positioning sliding seats 42 in the bottom support member 401 and the top support member 402. The lifting cylinder 405 is controlled to be opened to drive the top support member 402 to move downward until the sphere 5 is movably clamped between a plurality of positioning sliding seats 42 in the bottom support member 401 and the top support member 402, and the outer wall of the sphere 5 contacts a plurality of anti-slip pads 421, so as to perform double cross-section support clamping and positioning on the upper half and the lower half of the sphere 5, prevent the subsequent sphere 5 from rolling in the fixture, affect the stable drilling of the subsequent sphere 5, and further improve the processing quality of the ball valve.

[0028] The flipping member 2 includes two support frames 21 distributed symmetrically. The support frames 21 are fixedly installed on the top end of the mounting seat 1.

The mounting frames 23 are fixedly installed on the base 3. A positioning column 24 is movably clamped in the middle of the support frame 21. The positioning column 24 is movably clamped at the bottom end of the corresponding mounting frame 23. An auxiliary frame 241 is fixedly installed on one side of the outer wall of the support frame 21 close to the positioning column 24. A telescopic cylinder 242 is fixedly installed in the middle of the auxiliary frame 241. The driving end of the telescopic cylinder 242 is fixedly installed with one end of the positioning column 24. By providing the positioning column 24, the positioning column 24 is movably clamped at the bottom end of the corresponding mounting frame 23 to limit the rotation of the mounting frame 23 and prevent the base 3 and the positioning member 4 from flipping, further improving the stability of the sphere 5 processing.

[0029] Worm wheels 25 are fixedly installed at the opposite ends of the rotation axis 22. A worm 251 is meshed and connected to the outer side of the worm wheel 25. The worm 251 is rotatably installed on the support frame 21. A second motor 252 is fixedly installed on one side of the outer wall of the support frame 21 close to the worm 251. The driving end of the second motor 252 and one end of the worm 251 are fixedly installed. After the sphere 5 is processed, the telescopic cylinder 242 is controlled to expand and contract, driving the positioning column 24 to slide and disengaging from the mounting frame 23. Subsequently, the second motor 252 is controlled to drive the worm 251 to drive the worm wheel 25 and the rotation axis 22 to rotate, thereby driving the mounting frame 23, the base 3, and the positioning member 4 to flip. Subsequently, the lifting cylinder 405 is controlled to extend, and the sphere 5 loses its positioning and automatically drops for automatic material discharging, thereby improving the processing efficiency of the sphere 5.

[0030] Working principle: During use, first, according to the different aperture sizes of the sphere 5, the distances between multiple positioning sliders 42 in the bottom support member 401 and the top support member 402 are adjusted. The first motor 452 is controlled to drive the drive shaft 451 and the gear 45 to drive the driven tooth ring 44 and the drive ring 43 to rotate. Cooperating with the flat thread protrusion being movably clamped in the flat thread groove, multiple positioning sliders 42 are driven to move towards each other. On the contrary, the first motor 452 is controlled to drive the drive shaft 451 and the gear 45 to drive the driven tooth ring 44 and the drive ring 43 to rotate in the reverse direction. Cooperating with the flat thread protrusion being movably clamped in the flat thread groove, multiple positioning sliders 42 are driven to move away from each other, flexibly adjusting the distances between multiple positioning sliders 42 to adapt to the subsequent support, clamping, and positioning of spheres 5 with different aperture sizes.

[0031] During clamping and positioning, the lifting cylinder 405 is controlled to drive the top support member 402 to move upward. Subsequently, the sphere 5 is placed between multiple positioning sliders 42 in the bottom support member 401 and the top support member 402. The lifting cylinder 405 is controlled to drive the top support member 402 to move downward until the sphere 5 is movably clamped between multiple positioning sliders 42 in the bottom support member 401 and the top support member 402. The outer wall of the sphere 5 contacts multiple anti-slip pads 421, providing double cross-sectional support, clamping, and positioning for the upper and lower halves of the sphere 5, preventing the subsequent sphere 5 from rolling in the fixture and affecting the stable drilling of the subsequent sphere 5, thereby improving the processing quality of the ball valve.

[0032] After the sphere 5 is processed, the telescopic cylinder 242 is controlled to expand and contract, driving the positioning column 24 to slide and disengaging from the mounting frame 23. Subsequently, the second motor 252 is controlled to drive the worm 251 to drive the worm wheel 25 and the rotation axis 22 to rotate, thereby driving the mounting frame 23, the base 3, and the positioning member 4 to flip. Subsequently, the lifting cylinder 405 is controlled to extend, and the sphere 5 loses its positioning and automatically drops for automatic material discharging, thereby improving the processing efficiency of the sphere 5.
