置。 A hollow rotary cylinder device having a chuck at the front and attached to the rear of a spindle passing through a machine body to open and close the chuck,
A piston fixed to the connecting rod for opening and closing the chuck is fitted into a cylinder fixed on the same axis to the spindle so as to be movable in the front and rear direction, and a cylindrical distributor shaft fixed on the same axis at the rear of the cylinder. , through the bearing,
A housing fixed to the machine body is rotatably fitted, and a perfect circular groove is formed on one side of the facing surface of the housing and the distributor shaft, extending all the way around the front and back, and on the other side, both perfect circular grooves are formed. A hole is formed that opens to the piston in the cylinder, and a conduit passage that opens on both sides of the piston in the cylinder is communicated with both the holes or both circular grooves through the cylinder and the distributor shaft, and a compressed air source is connected to both the circular grooves. and atmosphere can be connected alternately,
Alternatively, a compressed air source and the atmosphere can be connected alternately to both holes, and a heat-resistant and abrasion-resistant sealing material is interposed in a pressed state over the entire circumference of both sides of the surface facing the perfect circular groove and the hole. Hollow rotary cylinder device.
