[0026] In this embodiment, during operation, the workpiece that needs fine milling is placed in the middle of the fine milling table 1, and the two motors 7 are started simultaneously by the same controller. After the two motors 7 are started, the threaded rod 8 is driven to rotate. After the threaded rod 8 rotates, the sleeve 9 is driven forward. When the sleeve 9 is pushed forward, the push bar 2 is driven forward synchronously until the three movable chucks 301 are against the outside of the workpiece, thereby achieving the purpose of facilitating quick clamping.

[0027] like Figure 4 As shown, guide rods 10 are fixedly installed at both ends of the push bar 2 near the transmission housing 6, and guide grooves 11 are provided on both sides of the transmission housing 6, and the guide rods 10 are slidably connected with the guide grooves 11;

[0028] In this embodiment, when the push bar 2 moves forward and backward, the guide rods 10 at both ends of the push bar 2 will slide along the inside of the guide groove 11, so that the sleeve 9 can move along a straight line, thereby achieving the purpose of facilitating guidance.

[0029] like Figure 1 and Figure 3 As shown, guide rails 401 are fixedly installed at both ends of the middle part of one side of the push bar 2 close to the movable clamp 301, and sliders 402 are movably installed on the inner sides of the two guide rails 401.

[0030] In this embodiment, when it is necessary to clamp a special-shaped workpiece, taking the case where there is a protrusion on the outside of the workpiece as an example, when the three movable chucks 301 are against the outside of the workpiece, the movable chuck 301 close to the protrusion will retreat, and when the movable chuck 301 at this position retreats, the two movable chucks 301 at other positions will translate outward, and at the same time, the connecting rod 302 drives the slider 402 to adaptively adjust its position laterally inside the guide rail 401 until the three movable chucks 301 stop after clamping the workpiece, thereby achieving the purpose of facilitating automatic adjustment.

[0032] In this embodiment, side blocks 403 are fixedly installed on both sides of the guide rail 401 , wherein the side blocks 403 are used to limit the lateral position of the slider 402 to prevent the slider 402 from falling off from both sides of the guide rail 401 .

[0033] Working principle: during operation, the workpiece to be fine-milled is placed in the middle of the fine-milling table 1, and the two motors 7 are started simultaneously by the same controller. After the two motors 7 are started, the threaded rod 8 is driven to rotate, and the threaded rod 8 is driven to push the sleeve 9 forward after rotating. When the sleeve 9 is pushed forward, the push bar 2 is pushed forward synchronously until the three movable chucks 301 are against the outside of the workpiece, thereby achieving the purpose of facilitating quick clamping; when it is necessary to clamp a special-shaped workpiece, taking the outside of the workpiece with a bump as an example, when the three movable chucks 301 are against the outside of the workpiece, the movable chuck 301 close to the bump position will retreat, and the opposite is true when a groove appears. When the movable chuck 301 at this position retreats, the two movable chucks 301 at other positions will translate outward, and the translation direction is opposite when a groove appears. At the same time, the connecting rod 302 drives the slider 402 to adaptively adjust its position laterally inside the guide rail 401 until the three movable chucks 301 clamp the workpiece and stop.
