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
- Double-acting design: swings and clamps downward when pressurized, lifts and returns when released.
- Swing angle options: commonly 90° and 180°, available in both left-hand and right-hand rotation.
- Compact structure: short cylinder body, ideal for installation in fixtures or CNC tooling.
- Customizable clamping arms: adaptable with different jaws or clamp arms for various workpieces.
- Fast action: pneumatic drive ensures quick clamping and releasing.
- Safe and reliable: certain models feature dust-proof and coolant-resistant designs for longer service life.
- Mounting method: install the external thread using a locknut directly on the fixture plate; the height relative to the workpiece is adjustable.
Applications
Pneumatic swing clamp cylinders are widely used in CNC machining, jigs & fixtures, and automated production lines. Typical applications include:
- 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.
- Automated assembly lines: for stations requiring positioning and holding of workpieces; swing clamps provide stable clamping for subsequent assembly operations.
- Welding jigs: provides secure clamping in limited spaces and allows quick release after welding.
- Inspection fixtures: holds test samples securely, ensuring stability during inspection and measurement.
- 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.
