MRHQ Rotary Air Gripper User Guide
Product Overview
The MRHQ series rotary air gripper represents SMC's innovative solution that seamlessly integrates gripping and rotating functions into a compact unit. Designed specifically for handling and reversing workpieces on transfer lines, this all-in-one system eliminates the need for peripheral piping and wiring associated with traditional combinations of rotary tables and air grippers.
Featuring a modular construction, the MRHQ series supports five-directional mounting and is compatible with magnetic switches for position detection. Standard swing angles are 90° and 180°, each adjustable by ±10° for precise positioning control. This versatile gripper is ideal for automated production lines, assembly processes, and robotic systems, combining efficiency, precision, and space-saving design.

Operation Guide
-
Pre-start checks
- Confirm air supply pressure is within the specified range
- Check for correct piping connections
- Ensure operating temperature is within the allowable range
- Verify proper installation of fingers and fixtures
- Confirm swing range is correctly adjusted and no interference risks exist
-
Basic operation
- Control gripper opening/closing and swinging by supplying and exhausting compressed air
- Gripper opening/closing:
- Finger closing: Compressed air enters from the "close port"
- Finger opening: Compressed air enters from the "open port"
- Swing control:
- Forward swing: Compressed air enters from the "forward rotation port"
- Reverse swing: Compressed air enters from the "reverse rotation port"
-
Gripping force adjustment
- Adjust gripping force by regulating operating air pressure
- Higher air pressure results in greater gripping force
- Select appropriate gripping force based on workpiece weight and material
- Ensure sufficient gripping force to prevent workpiece slippage, but not excessive to cause workpiece deformation
-
Swing speed adjustment
- Adjust swing speed by regulating flow control valves
- Adjust both forward and reverse swing speeds to ensure smooth operation
- Avoid excessive speed that may cause impact and vibration
-
Position control
- Use magnetic switches to detect gripper opening/closing and swing positions
- Achieve precise position control through PLC or control system
- Adjust swing angle and position according to production requirements
