Pneumatic Swing Clamp Cylinder
Pneumatic Swing Clamp Cylinder is a clamping actuator powered by compressed air. Its unique feature is that the piston rod first performs a swinging (rotational) movement before moving downward in a linear clamping motion when extending or retracting. This mechanism effectively eliminates interference during workpiece loading and unloading, making it highly suitable for automated fixture design.

Key Features
1. Double-acting design: swings and clamps downward when pressurized, lifts and returns when released.
2. Swing angle options: commonly 90° and 180°, available in both left-hand and right-hand rotation.
3. Compact structure: short cylinder body, ideal for installation in fixtures or CNC tooling.
4. Customizable clamping arms: adaptable with different jaws or clamp arms for various workpieces.
5. Fast action: pneumatic drive ensures quick clamping and releasing.
6. Safe and reliable: certain models feature dust-proof and coolant-resistant designs for longer service life.
7. Flexible installation: can be mounted from the top or bottom, and directly fixed onto the fixture plate with screws.
8. Magnetic ring & sensor compatibility: cylinder body is equipped with a magnetic ring. By installing sensors in the cylinder’s sensor slot, both clamping and unclamping positions can be detected, meeting automation requirements.

Applications
Pneumatic swing clamp cylinders are widely used in CNC machining, jigs & fixtures, and automated production lines. Typical applications include:
1. CNC machining fixtures: used on milling machines and machining centers, suitable for complex-shaped workpieces requiring quick clamping; prevents interference issues common with conventional straight push cylinders.
2. Automated assembly lines: for stations requiring positioning and holding of workpieces; swing clamps provide stable clamping for subsequent assembly operations.
3. Welding jigs: provides secure clamping in limited spaces and allows quick release after welding.
4. Inspection fixtures: holds test samples securely, ensuring stability during inspection and measurement.
5. Electronics or small workpiece clamping: offers gentle yet reliable clamping for fragile or easy-to-shift parts.

Conclusion
The greatest advantage of pneumatic swing clamp cylinders lies in their integrated motion: swing → downward clamping → quick release. This not only avoids interference but also enhances automation efficiency, making them one of the most common pneumatic components in CNC machining and fixture systems.
