[0030] When processing the ball valve, it is inevitable to rotate the ball valve. A circular groove 26 is provided on the upper surface of the bottom tray 18, and the ball valve can be placed on the circular groove 26, and at this time there is a gap between the ball valve and the bottom surface of the circular groove 26. A square channel 27 is also provided on the bottom tray 18, and the square channel 27 horizontally penetrates the bottom tray 18, that is, the square channel 27 extends along the radial direction of the bottom tray 18. At this time, the square channel 27 is connected with the circular groove 26, and a displacement long plate 28 passes through the square channel 27, and the displacement long plate 28 can contact the ball valve.

At this time, the displacement long plate 28 can be pulled out to achieve the rotation of the ball valve. However, it should be noted that the spherical clamping component 12 is rotatable at this time. In order to facilitate the pulling out of the displacement long plate 28, a ball is provided on the upper surface of the positioning disc 31 to reduce the friction between the two. By rotating the handle 32, the positioning disc 31 moves the displacement long plate 28 upward, so that the displacement long plate 28 is in close contact with the ball valve, and the pull rod 29 on the displacement long plate 28 is pulled to move the displacement long plate 28 along the length of the square channel 27. The ball valve can be rotated to achieve the purpose of rotating the ball valve. By analogy, all the punching work of the ball valve is completed.

[0032] During implementation, the component is in the initial state. First, the ball valve is placed in the spherical groove 16 on the bottom tray 18. At this time, the lower surface of the ball valve contacts the upper surface of the displacement long plate 28. The ball valve is rotated to make it located at the position where the hole is to be punched. The handle 10 on the push threaded rod 7 is rotated to move the movable clamping plate 4. At this time, the limit slider 19 on the movable plate 5 moves in the slide groove 33 in the workbench 1. At the same time, the vertical position of the spherical stabilizing component 12 on the first vertical support plate 2 and the fixed plate 6 is fine-tuned until the ball valve is tightly attached to the spherical stabilizing component 12 on the first vertical support plate 2 and the spherical stabilizing component 12 on the fixed plate 6. The locking nut 22 on the limit slider 19 and the locking disk 25 on the bottom tray 18 are tightened to determine the horizontal position of the ball valve. At this time, the ball valve is between the first vertical support plate 2 and the movable clamping plate 4. The handle 32 under the workbench 1 is rotated to adjust the displacement long plate 28 and the positioning disc 31 in the bottom tray 18. The distance between the two is such that the two are in close contact, that is, the displacement long plate 28 is in close contact with the ball valve, and then the bolts on the spherical stabilizing clamping component 12 are tightened to determine the vertical position of the ball valve. At this time, the ball valve can be punched. After the punching is completed, the pull rod 29 on the displacement long plate 28 is pulled. At this time, the spherical stabilizing clamping component 12 can be rotated to make the ball valve located at the next position to be processed. By analogy, the punching work of the ball valve is completed. After the punching is completed, the handle 32 under the workbench 1 is rotated to separate the displacement long plate 28 from the positioning disc 31, and there is a certain distance between the two. Then, the locking plate 25 on the bottom tray 18 and the bolts on the spherical stabilizing clamping component 12 are loosened. At this time, the vertical position of the ball valve can be moved, and then the handle 10 on the flat push threaded rod 7 is rotated to make the ball valve between the first vertical support plate 2 and the fixed plate 6, and does not contact them. At this time, the ball valve is not constrained, and the ball valve can be taken down from the assembly to enter the next processing link.
