[0026] As Figs. 1 to 3As shown, a high-precision lightweight rotary chuck integrated with a chuck and a cylinder includes a base plate 1 and a collet chuck wrench 9. The base plate 1 is fixedly installed with a body 2. The body 2 is internally provided with a sliding sleeve 3 which can slide axially along the body 2 for transmitting the driving force of the cylinder. The sliding sleeve 3 is internally installed with a piston 4 which is in close cooperation with the sliding sleeve 3. The piston 4 moves up and down under the action of gas pressure to drive the sliding sleeve 3. The body 2 is provided with a static iron ring 5. The surface of the static iron ring 5 is provided with an A gas inlet hole 11 and a B gas inlet hole 12 for guiding high-pressure gas into different chambers of the cylinder to control the movement direction of the piston 4.

The inner hole of the spring collet 10 can be contracted or expanded for clamping or releasing workpieces. More specifically, when high-pressure gas enters the chuck from the A gas inlet hole 11 on the static iron ring 5, the high-pressure gas enters the hole below the static iron ring 5 and then enters the hole on the base plate 1, thereby continuing to enter the cylinder and then entering the gas chamber above the piston 4 to drive the piston 4 downward. The piston 4 is separated from the spring collet 10, and the spring collet 10 is expanded under the action of its own elastic force. At this time, the workpiece can be put in. The gas inlet direction is switched so that the high-pressure gas enters the chuck from the B gas inlet hole 12 on the static iron ring 5. The high-pressure gas enters the hole above the static iron ring 5, then enters the base plate 1, thereby continuing to enter the cylinder and then entering the gas chamber below the piston 4 to drive the piston 4 forward.

More specifically, through the high-precision cooperation of the sliding sleeve 3 and the piston 4, the precision and response speed of the gas pressure transmission are ensured, and the clamping and releasing actions of the chuck are rapid and accurate.

[0029] The copper sleeve 6 is made of self-lubricating copper alloy material. More specifically, the copper sleeve 6 is made of self-lubricating copper alloy material which has good wear resistance and does not need additional lubrication, thereby reducing maintenance costs and ensuring the smoothness of the long-term relative motion between the static iron ring 5 and the body 2.

[0030] The spring collet 10 is made of high-precision spring steel material with good elastic performance.
