The positioning block 2 and the pressure block 3 are respectively matched and connected with the valve ports at the upper and lower ends of the vacuum ball valve 10, and a through hole 6 is provided at the center position of the positioning block 2 and the pressure block 3. A positioning groove 7 matching the positioning block 2 is provided on the base 1, and a threaded hole 8 threadedly connected to one end of the screw 4 is provided at the center position of the positioning groove 7. The end of the screw 4 away from the threaded hole 8 passes through the positioning block 2, the vacuum ball valve 10 and the pressure block 2 in sequence and is threadedly connected to the nut 5, thereby fixing the vacuum ball valve 10 on the base 1.

[0021] In the above embodiment, first, the positioning block 2 is placed in the matching positioning groove 7, one end of the screw 4 passes through the through hole 6 on the positioning block 2 and is threadedly connected to the threaded hole 8 at the center of the positioning groove 7; then, the vacuum ball valve 10 to be processed is sleeved on the screw 4 and the valve port of one end of the vacuum ball valve 10 is docked with the positioning block 2, while the pressing block 3 is docked with the valve port of the other end of the vacuum ball valve 10 and the end of the screw 4 away from the positioning block 2 passes through the through hole 6 on the pressing block 3, and finally, the nut 5 is threadedly connected to the screw 4 so that the pressing block 3 and the positioning block 2 are fixedly positioned on the vacuum ball valve 10 to be processed, thereby realizing the rapid clamping and positioning of the vacuum ball valve 10. Therefore, the tooling in this application can make the processing process of the vacuum ball valve 10 more stable and smooth, effectively improve the processing efficiency, and ensure the processing quality of the product.

[0022] It should be noted that the cross-sections of the positioning block 2 and the pressing block 3 are both circular, and the positioning groove 7 is a circular groove; the through hole 6 can also be a threaded hole matching the screw; the screw 4 can also be a double-headed screw with no threads in the middle and threads at both ends.

[0027] In some embodiments, a gasket (not shown) is further included, which is located between the nut 5 and the pressing block 3.

[0028] In the above embodiment, the gasket is arranged between the nut 5 and the pressing block 3, which can avoid direct contact between the nut 5 and the pressing block 3, thereby reducing the friction loss between the nut 5 and the pressing block 3, thereby extending the service life of the components.

[0029] In some embodiments, the positioning block 2 and the positioning groove 7 are clearance-fitted.

[0030] In the above embodiment, the positioning block 2 and the positioning groove 7 are clearance-fitted, so that the center distance of the vacuum ball valve 10 to be processed can be fine-tuned by the positioning block 2, thereby making the vacuum ball valve 10 parallel and perpendicular to the center line. The pressure block 3 and the nut 5 can then be used to stably fix the vacuum ball valve 10 to be processed on the base 1, ensuring that the product will not move during the subsequent processing of the valve body.
