Detailed description of the invention
Below in conjunction with accompanying drawing the utility model braking device for main-shaft made and further illustrating.
A kind of braking device for main-shaft, is shown in Figure of description 1, comprises cylinder body 1, symmetrical two pistons 2 be arranged in cylinder body 1, clamping plate 3, gripper shoe 4, first oil pipe 5 being fixed on outer wall on cylinder body 1 and the second oil pipe 6;
Piston 2 comprises piston head 7 and piston rod 8, its all with cylinder body 1 contact internal walls, and can slide along cylinder body 1 inwall, two piston heads 7 and cylinder body 1 inwall form the first confined space 9, and piston head 7, piston rod 8 and cylinder body 1 inwall form the second confined space 10; Piston rod 8 one end is fixedly connected with symmetrically arranged clamping plate 3, and the other end is fixedly connected with piston head 7; Two clamping plates 3 are flexibly connected with gripper shoe 4 two ends respectively, make clamping plate 3 can be that axle swings with junction; First oil pipe 5 and the second oil pipe 6 are arranged on cylinder body 1, and the first oil pipe 5 communicates with the first confined space 9, and the second oil pipe 6 communicates with the second confined space 10.
Cylinder body 1 can also be provided with cylinder cap 11, see Figure of description 1, cylinder cap 11 communicates with the second confined space 10.
This braking device for main-shaft can also comprise the first support 12, second support 13 and spindle box body 14, sees Figure of description 2, and cylinder body 1 is fixedly connected with spindle box body 13 with the second support 12 by the first support 11.
