Referring to fig. 1 to 3, a clamping structure for a numerical control machine tool according to the present invention includes a housing 10, a transition plate 20, a pushing structure 30, a clamp 40, a first screw 50, and a second screw 60.
The housing 10 includes a connection plate 11, a body 12, and a first fastening member 13. The connecting disc 11 is fixed to the machine tool spindle. The first fastener 13 is a socket head cap screw. The body 12 is provided with a threaded bore 120.
The transition disc 20 comprises a fixed end 21 and a protrusion 22. The projection 22 extends from the fixed end 21, and the projection 22 has a cylindrical shape. The fixing end 21 is provided with a through hole.
The pushing structure 30 includes a push-pull sleeve 31, a taper sleeve 32, and a second fastener 33. The end of the cone sleeve 32 is provided with a conical surface 320. The second fastener 33 is a socket head cap screw.
The jig 40 includes a mounting portion 41 and a plurality of collets 42. A plurality of collets 42 extend from the mounting portion 41. A gap exists between two adjacent collets 42. A plurality of collets 42 form a gripping portion 43 therebetween. Each collet 42 is provided with a pressure receiving surface 420. The compression surface 420 is tapered, and the taper of the compression surface 420 is matched with the taper surface 320.
The first jackscrew 50 and the second jackscrew 60 are both provided with external threads.
When assembling the clamping structure for the numerical control machine tool, the taper sleeve 32 is sleeved on the clamp 40, the mounting portion 41 of the clamp 40 is provided with an internal thread, the protrusion 22 is provided with an external thread, and the internal thread of the mounting portion 41 is matched with the external thread of the protrusion 22, so that the mounting portion 41 is fixed on the protrusion 22. The push-pull sleeve 31 is inserted into the transition disc 20, and the second fastening member 33 is mounted on the push-pull sleeve 31 and is matched with the taper sleeve 32, so that the push-pull sleeve 31 and the taper sleeve 32 are fixedly connected to form the push structure 30. The pushing structure 30 is now movably mounted to the transition tray 20. The fixed end 21 of the transition disc 20 is located between the connection disc 11 and the main body 12. The first fastening member 13 is mounted to the body 12 and fitted to the connection plate 11 through the through hole of the fixing end 21 to fixedly connect the connection plate 11, the transition plate 20 and the body 12.
