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. Mounting method: available with top-flange or external-thread installation, fixed to the fixture plate by screws or locknut, with adjustable height relative to the workpiece.

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.
