Preferably, circular cone and driven pulley are provided on the main shaft, the circular cone is welded in main shaft leading portion, institute
It states driven pulley and main shaft back segment is mounted on by bolt.
Preferably, the circular cone front end is in hollow structure, and circular cone rear end offers through slot in cross distribution.
Preferably, the tab nose is welded with pull rod in cross distribution, and the pull rod is nested in through slot, and before pull rod
End is connected with connecting rod by shaft, and the connecting rod front end is connected with I-shaped sliding block by shaft, and the I-shaped sliding block is nested
In in sliding slot, I-shaped slip front is mounted with claw by bolt, and the claw front end is symmetrically welded with crushing block.
Preferably, first motor, the second motor and bearing block are provided on the pedestal, the first motor passes through bolt
It is mounted on pedestal top rear, and main pulley, second electricity are mounted with by bolt on first motor main shaft
Machine is mounted on pedestal top nose by bolt, and the second electric machine main shaft upper pin is connected with drive screw, the bearing
Seat is mounted on middle section at the top of pedestal by bolt, and bearing block is connect by bearing with the interference of drive screw rear end.
Preferably, the driven pulley and main pulley are cast iron quality, and driven pulley passes through belt and master
Belt pulley is connected.
Preferably, slide is threaded on the drive screw, the slide top is welded with support column, the support
Column top is welded with main pull ring, and the main pull ring is connect by bearing with pull ring interference.
Preferably, the first motor is electrically connected with digital control system respectively with the second motor.
Compared with prior art, the beneficial effects of the present invention are: driven pulley of the present invention passes through belt and main pulley
It is connected, easily main shaft can be driven to be rotated under the action of first motor;It is threaded with slide on drive screw, can lead to
Crossing drive screw easily drives slide straight line to be slided;Main pull ring is connect by bearing with pull ring interference, can be light by slide
Pine pulls pull ring;I-shaped sliding block is nested in sliding slot, can easily drive I-shaped sliding block along sliding slot by pull ring
It is clamped or unclamps simultaneously;Circular cone front end is in hollow structure, easily can carry out shrinkage operation to connecting rod;Connecting hole is in cross
It is distributed and is set on the outside of fixed disk, easily fixed disk can be installed on numerically-controlled machine tool.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Whole elaboration.
As shown in Figs. 1-5, a kind of numerically-controlled machine tool clamp structure, including fixed disk 1, pull ring 2 and pedestal 3 are set in fixed disk 1
It is equipped with connecting hole 4 and stepped hole 5, connecting hole 4 is opened in 1 outside of fixed disk in cross distribution, and stepped hole 5 is opened in fixed disk 1
Front end, and stepped hole 5 is connected with chuck 6 by bearing interference, sliding slot 7 and main shaft 8 is provided on chuck 6, sliding slot 7 is in cross point
Cloth is opened in 6 outside of chuck, and main shaft 8 is welded among 6 rear end of chuck, and pull ring 2 is set in 8 middle section of main shaft, and pedestal 3 is placed in master
8 lower section of axis.
Fixed disk 1: being mounted on numerically-controlled machine tool by specifically used mode by connecting hole 4, then by 8 rear end of main shaft
It is connect by bearing with numerically-controlled machine tool inner wall interference;When needing to carry out clamping to workpiece, pass through the second electricity of digital control system manipulation
Machine 18 is rotated, and the rotation of the second motor 18 drives drive screw 22 to be rotated, and the rotation of drive screw 22 drives slide 23 straight
Line is slided backward, and slide 23, which slides backward, drives support column 24 to pull pull ring 2, is driven after 2 under tension of pull ring
The connecting rod 13 of 12 front end of pull rod is slided backward along through slot 11, and connecting rod 13 slides backward and touches the inner wall of circular cone 9
After shunk, connecting rod 13 shrink drive claw 15 along sliding slot 7 inwardly simultaneously gather to workpiece carry out clamping;Finally by number
Control system manipulation first motor 17 is rotated, and the rotation of first motor 17 drives main pulley 20 to be rotated, main pulley 20
Rotation by belt 21 drive driven pulley 10 on main shaft 8 rotated, main shaft 8 rotation drive chuck 6 on workpiece into
Row rotation, while pull rod 12 drives pull ring 2 to be rotated around main pull ring 25 under the rotation of main shaft 8.
The above is present pre-ferred embodiments, for the ordinary skill in the art, according to the present invention
Introduction, in the case where not departing from the principle of the present invention and spirit, changes, modifications, replacement and change that embodiment is carried out
Type is still fallen within protection scope of the present invention.
