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
