KQ Front-mounted pneumatic chuck
Category:
Short cylinder front-lock screw connection form
The chuck is easy to install, with a connection method that complies with industry standards, eliminating the need to modify the original machine tool structure; the cylinder and chuck are integrally designed, allowing a single chuck to be mounted on both the front and rear sides of machine tools for simultaneous use.
The chuck features a large bore diameter, incorporates a one-way valve, and provides reliable clamping; moreover, when the chuck is rotating, the sealing device is disengaged, thereby ensuring a long service life.
Working principle: the clamping power source of the chuck is compressed air; when compressed air flows into the one-way valve through a distributing ring and then into the chuck cylinder, thus to drive the piston, so that the jaw clips a workpiece tightly; then, the reversing valve is powered off, and the air pressure within the cylinder is sealed by the one-way valve. The sealing device of the distributing ring is released, not to contact the chuck body, and the equipment can be started for normal work at this time.
Note: Because the chuck is ventilated in the clamping and released state, and the special sealing element on the distributing ring clamps the excircle of the chuck body tightly, so the machine tool spindle should stop rotating while the chuck is clamping and releasing the workpiece.
