[0027] Specifically, the four supporting arms 33 are arranged in an annular array, and the outer surfaces of the four supporting arms 33 are provided with anti-skid soft pads, which can uniformly support and fix the valve. The anti-skid soft pads increase the friction with the valve, avoid sliding of the valve during processing, improve the stability of positioning, one end of each of the four supporting arms 33 is fixedly connected with a guide block 36, one end of the vertical plate 2 is provided with a guide groove 34 matched with the four guide blocks 36, and the cooperation of the guide block 36 and the guide groove 34 ensures the linearity and accuracy of the movement of the supporting arm 33, and further enhances the reliability of the positioning tool.

[0028] As shown in Figures 1 to 4 , one end of the adjusting screw rod 35 away from the power motor 4 is fixedly connected with a limiting plate 31, the limiting plate 31 prevents the rotating block two 32 from falling off the adjusting screw rod 35, avoids faults and safety hazards caused by falling off of parts, prolongs the service life of the positioning tool, and ensures the safety and stability of the operation of the entire device.

[0029] Further, the rotating block one 37 is rotatably connected with the adjusting screw rod 35 through a bearing, which reduces the friction during rotation, reduces energy loss, and makes rotation smoother.

[0030] As shown in Figures 1 to 4 , the supporting mechanism 5 comprises a moving frame 52, the moving frame 52 is slidably connected with the workbench 1, the top end of the moving frame 52 is fixedly connected with two electric telescopic rods 53, the top ends of the two electric telescopic rods 53 are fixedly connected with a supporting rod 54, the moving frame 52 in the supporting mechanism 5 is slidable, the electric telescopic rods 53 are telescopic, and the supporting rod 54 can be adjusted in height according to valves of different heights, which improves the versatility and flexibility of the positioning tool and can adapt to the processing needs of valves of different specifications, thereby expanding the application range of the positioning tool.

[0031] It is worth noting that the top end of the support rod 54 is arc-shaped, which is more in line with the shape of the valve, can better support the valve, avoid damage to the surface of the valve, improve the support effect of the positioning tool on the valve, and at the same time ensure the stability of the valve during machining.

Therefore, the control mode and wiring arrangement of the motor will not be explained in detail.

[0034] Working principle and process: when working, the power motor 4 starts to drive the adjusting screw 35 to rotate. The rotation of the adjusting screw 35 will make the rotating block two 32 screwed on it move along the screw axis. Since the rotating block one 37 is rotatably connected with the adjusting screw 35, and the rotating block one 37 and the rotating block two 32 are rotatably connected with the supporting arm 33 through the connecting rod 38, the movement of the rotating block two 32 is converted into the linear sliding of the supporting arm 33 on the vertical plate 2 through the connecting rod 38. The four supporting arms 33 arranged in a ring array move inward or outward under the guidance of the guide block 36 and the guide groove 34, so as to fix or loosen the valve. At the same time, the moving frame 52 in the supporting mechanism 5 can slide on the electric sliding rail 51, so that the supporting device can support valves of different lengths. The sliding of the sliding block 551 in the sliding groove 55 ensures the stability of the movement of the moving frame 52. The height of the support rod 54 can be adjusted through the extension and retraction of the electric telescopic rod 53, and the arc-shaped design of the top end of the support rod 54 can better fit the valve and support the valve.
