The three guide grooves 9 are each slidably installed with a clamping rod 4. When in use, the control valve to be processed can be placed between the three clamping rods 4. At this time, the tightening rod 7 is driven by a wrench to rotate clockwise. When the tightening rod 7 rotates clockwise, it drives the rotating shaft 5 to rotate forward through the bevel gear 8. At this time, the adjusting frame 6 outside the rotating shaft 5 will also rotate forward. Therefore, the cylindrical block at the left end of the clamping rod 4 can be used to push the clamping rod 4 to slide in the guide groove 9 toward the end near the middle position of the clamping head 3.

When the fastening rod 7 rotates, the bevel gear 8 at its bottom end can cooperate with the bevel gear 8 on the outside of the rotating shaft 5 to drive the rotating shaft 5 to rotate synchronously, so that the adjusting frame 6 can drive the clamping rod 4 to move.

[0031] In the embodiment of the present disclosure, Figure 2-Figure 6As shown, the guide grooves 9 are all arc-shaped grooves, and one end of the three guide grooves 9 is close to the center position of the clamping head 3, and the other end of the guide groove 9 is close to the edge position of the clamping head 3. When the adjusting frame 6 rotates in the reverse direction, the cylindrical block at the left end of the clamping rod 4 can be used to push the clamping rod 4 to slide in the guide groove 9 toward the end close to the edge position of the clamping head 3. During this process, the clamping rod 4 will gradually move away from the middle position of the clamping head 3, and then the control valve to be processed can be placed between the three clamping rods 4.

Therefore, the cylindrical block at the left end of the clamping rod 4 can push the clamping rod 4 to slide in the guide groove 9 toward the end close to the edge of the clamping head 3. In this process, the clamping rod 4 will gradually move away from the middle position of the clamping head 3, and the cylindrical block at the left end of the clamping rod 4 will also move in the adjusting frame 6. When the tightening rod 7 rotates clockwise, the tightening rod 7 will drive the rotating shaft 5 to rotate forward through the bevel gear 8. At this time, the adjusting frame 6 on the outside of the rotating shaft 5 will also rotate forward. Therefore, the cylindrical block at the left end of the clamping rod 4 can be used to push the clamping rod 4 to slide in the guide groove 9 toward the end close to the middle position of the clamping head 3.

Therefore, the clamping rod 4 can be tightly attached to the outer wall of the control valve, so that the control valve can be firmly clamped and fixed. Then, the CNC lathe can be controlled by the controller 2 to process the control valve.
