[0018] See also Figures 1 to 3 , the utility model provides a technical solution:

[0019] A clamping structure for a numerically controlled machine tool comprises a base 1, a support frame 2 symmetrically mounted on the base 1, a workbench 3 mounted between the support frames 2 and a top seat 4 on the top, a slide groove is provided on one side of the support frame 2, a rotating shaft 6 is mounted in the slide groove, a sliding sleeve 5 is sleeved on the outer side of the rotating shaft 6, a driving shaft rotation driving assembly is mounted inside the top seat 4, a mounting seat 7 is provided between the sliding sleeves 5, an electric push rod 8 is fixed above the mounting seat 7, an output shaft end of the electric push rod 8 passes through the mounting seat 7 and is connected to a connecting plate 9, a clamp 10 is movably connected on the mounting seat 7 and on both sides of the connecting plate 9, the clamp 10 and the connecting plate 9 are movably connected through a plurality of connecting rods 11, and a clamp 12 is installed below the clamp 10.

[0020] During operation, the position of the clamp can be adjusted according to the actual processing needs. When it is necessary to clamp the suspended parts, the electric push rod 8 drives the connecting plate 9 to rise and fall. During the lifting process, the connecting plate 9 drives the connecting rod 11 to adjust the distance between the two clamps 10, so that the parts are clamped and fixed by the clamp 12. Then, the driving assembly drives the rotating shaft 6 to rotate, so that the sliding sleeve 5 drives the mounting seat 7 to move, so that the parts leave the workbench 3, thereby achieving the purpose of suspended clamping.

[0021] The driving assembly includes a bevel gear 1 and a bevel gear 2 which are symmetrically installed in the top seat 4 and meshed with each other. One end of the rotating shaft 6 extends into the top seat 4 and is connected to the bevel gear 1. A movable shaft 13 runs through the bevel gear 2. A servo motor 14 for driving the movable shaft 13 to rotate is installed outside the top seat 4. The servo motor 14 drives the movable shaft 13 to rotate when it works, and with the cooperation of the bevel gear 1 and the bevel gear 2, the two rotating shafts 6 are driven to rotate.

[0022] An L-shaped fixing frame is symmetrically arranged inside the top seat 4, and the rotating shaft 6 and the movable shaft 13 respectively pass through the two ends of the L-shaped fixing frame to play the role of limiting support.

[0023] A thread groove is formed on the outer surface of one end of the rotating shaft 6 located in the slide groove, and the sliding sleeve 5 is spirally connected to the thread groove. When the rotating shaft 6 rotates, the sliding sleeve 5 is driven to move vertically on the rotating shaft 6 through the thread groove.

[0024] A rubber wear-resistant pad is installed on one side of the clamp 12 to enhance the reliability of clamping.
