Xi lanh kẹp xoay dòng QDK

The rotary motion occurs at a constant height (zero vertical travel), making it more suitable than the QCK series for space-constrained environments;
Flexible mounting options are available, with choices between a front-cover boss type and a front-cover flat type;
Features a dual-pin rotary guide slot design, ensuring smooth operation and high repeatability;
Sensor mounting slots are integrated into all four sides of the cylinder body, eliminating the need for additional mounting accessories and offering greater convenience and flexibility.

QDK series Swing clamp cylinder is a horizontal rotary clamping cylinder (also known as a rotary pneumatic cylinder). Unlike the QCK model—which descends while rotating—the QDK maintains a constant height during rotation (zero vertical travel during the rotary phase) and only performs the vertical clamping stroke after rotation is complete; it is designed primarily for use in tooling fixtures within confined spaces.

Operating Principle:
1. Horizontal Swivel Phase: The swing arm rotates 90° within a single horizontal plane; the piston rod height remains unchanged, allowing the arm to clear the top of the workpiece.
2. Vertical Clamping Phase: Once rotation is complete, the piston rod moves vertically downward—a short stroke of 5 mm—to clamp the workpiece.

There is no mechanical self-locking mechanism; the clamp releases upon loss of air pressure, so a continuous air supply is required to maintain clamping force. Clamping force is generated only during the downward stroke; the arm cannot exert clamping force during the rotation phase.

Planar rotary structure: The rotary motion is completed at the same horizontal level—meaning the vertical travel during rotation is zero.

Available with a clamping arm; please contact us for details and separate purchase.

Multiple mounting options: Available in a panel-mount type with a raised boss on the front cover or a type with a flat front cover.

Dual-pin rotary guide slot, featuring high repeat positioning accuracy.

Integrated sensor mounting slots (magnetic switch mounting slots)
