Professional Pneumatic Rotary Fixture

A: It is a compressed‑air powered device that clamps and rotates a workpiece in one action. Inside, a piston moves linearly; a spiral groove and roller mechanism turn that motion into rotation. Some models also have a separate rotary drive for continuous spinning.

A: Main uses:
(1)CNC machining- one setup allows multi‑side cutting, no re‑positioning errors;
(2)automation and robotic cells- they act as robot "hands" for welding, assembly, laser marking; (3) auto industry-for precise machining and welding of crankshafts and shafts. Also common in electronics, medical, and food packaging.

A: Look at these points: clamp force needed (based on part weight and cutting loads), shop air pressure (usually 0.3‑0.7 MPa), rotation angle and stroke (e.g., 90° or 180°), max load/torque rating, and mounting style (flange, base, or side). Always add a safety margin.

A: Use clean, dry air-filter to 5 µm or finer. Pressure: 0.3‑0.7 MPa (4‑10 bar). Install an F.R.L. unit (filter, regulator, lubricator) to protect the fixture. Normally, do not add an in‑line oiler unless specified-it may wash out factory grease. Flush pipes before connecting to avoid debris.

A: Yes, add speed control valves on the exhaust (meter‑out). Start from the slowest setting and increase gradually. Do not start from high speed, or you may overload the mechanism. If multiple fixtures are used, adjust each one separately.

A: Every shift: check air supply and drain filter water. Listen for leaks at the cylinder and rod. Run a cycle – look for sticking or odd noises. Lubricate rotating parts with grease regularly. Keep the surface clean. Periodically re‑check positioning accuracy.

A: Rotation jams or fails to start
Usually caused by contaminated air, chips caught in the groove, or worn rolling elements.Clean the air circuit and replace the balls and seals.
Clamping force feels weak
Often due to internal leaks, degraded seals, or insufficient line pressure.Swap out seals, readjust the regulator, and double‑check the air supply.
Rotation and clamping not in sync
Likely from excessive gear backlash or a sticky flow‑control valve.Realign or renew the gears, and flush the valve spool.
Loud clicking noise during operation
Points to worn gears or failing bearings.Take off the end cover and inspect the gear mesh.
Clamp arm shifts after clamping
The working pressure is set too low.Increase the pressure to at least the minimum specified value.

A: Do not mount horizontally – it shortens life and weakens clamping. The arm must clear the workpiece during its rotation path. Never move the part after clamping; release first if adjustment is needed. Do not pressurize both clamp and release ports at the same time. Inspect for shipping damage before fitting.

A: Good fixtures last over 10 million cycles with proper care. To extend life: keep air clean, use speed controls to avoid shocks, grease regularly, stay within rated torque, use the lowest pressure that still holds the part, and choose Viton seals for hot environments.

A: Yes,we can tailor to your part size, force, space, and special conditions (heat, dust, etc.).
