MHZ2 Parallel Type Air Gripper Operating Manual

1. Product Introduction

The MHZ2 Parallel Type Air Gripper by WENK Pneumatic is a high-precision pneumatic clamping tool featuring an integrated linear guide design that provides exceptional rigidity and accuracy. This product is suitable for industrial automation scenarios requiring precise clamping, particularly for robotic end-effectors, material handling, and precision assembly applications.

Key Features:

Integrated linear guide for high rigidity and precision

Parallel opening/closing motion ensuring uniform force distribution

High repeatability: ±0.01mm

Multiple bore sizes: 6mm, 10mm, 16mm, 20mm, 25mm, 32mm, 40mm

Both double-acting and single-acting operation modes

Multiple mounting configurations: five options on three sides

Magnetic switch compatibility for easy system integration

Standard, narrow, and flat finger options available

2. Working Principle

The MHZ2 gripper uses compressed air to drive the piston, achieving parallel opening and closing movements of the fingers:

Double-Acting Type:
- Clamping process: Compressed air enters one chamber of the cylinder, pushing the piston to move, causing the fingers to close parallelly through the transmission mechanism to clamp the workpiece
- Releasing process: Compressed air enters the other chamber of the cylinder, the piston moves in reverse, and the fingers open parallelly to release the workpiece
Single-Acting Type:
- Normally Closed (NC): Fingers remain closed when no air pressure is applied, open when compressed air is supplied
- Normally Open (NO): Fingers remain open when no air pressure is applied, close when compressed air is supplied

Key Operating Parameters:

Working medium: Clean compressed air (40μm filtration recommended)

Working pressure range:

Double-acting type: 0.15-0.7MPa

Single-acting type: 0.3-0.7MPa

Operating temperature range: -10-60℃

Lubrication: Non-lube

Repeatability: ±0.01mm

3. Installation and Connection

Installation Preparation:

Confirm that the installation environment meets temperature and humidity requirements

Prepare necessary installation tools and accessories

Check that the gripper exterior is intact without damage or deformation

Installation Steps:

Select Mounting Method:

Front mounting: Mount through the front flange

Side mounting: Mount through the side mounting holes

Bottom mounting: Mount through the bottom mounting holes

Five different mounting configurations are available based on actual needs

Secure the Gripper:

Use appropriate bolts (recommended strength grade 8.8 or higher)

Ensure the mounting surface is flat and bolt torque meets requirements

Avoid over-tightening which may cause cylinder body deformation

Air Pipe Connection:

Confirm air source pressure is within the specified range

Use appropriate air pipes and fittings to connect to air inlets

It is recommended to install filters and pressure regulators before the air inlet

Correctly connect air inlet and outlet according to markings on the cylinder body

Magnetic Switch Installation (optional):

Install magnetic switches in the reserved mounting slots on the cylinder body

Adjust switch position to ensure accurate piston position detection

Correctly connect electrical wiring according to switch instructions

4. Operating Instructions

Initial Use:

Slowly increase air pressure to working pressure, observe if the gripper moves smoothly

Test finger opening and closing movements, confirm no abnormal noise or jamming

Check if clamping force and repeatability meet working requirements

Daily Operation:

Workpiece Clamping:

Ensure workpiece dimensions are within the gripper's clamping range

Adjust workpiece position so that the clamping center aligns with the gripper center

Avoid eccentric clamping to prevent workpiece tilting or slipping

Select appropriate finger type based on workpiece characteristics

Pressure Adjustment:

Adjust working pressure according to workpiece weight and material

Use lower pressure for lighter or precision workpieces

Use higher pressure for heavier workpieces (not exceeding maximum working pressure)

Regularly check if pressure is stable

Maintenance:

Regularly check if air pipe connections are secure and free from leaks

Keep the gripper surface clean, prevent dust and impurities from entering

Check if fingers and guide rails are worn, replace if necessary

If not in use for a long period, release air pressure and keep fingers in open position

Safety Precautions:

Ensure all mounting bolts are securely tightened before operation

Avoid contact with moving parts when the gripper is working

Regularly check clamping status to ensure workpieces won't accidentally fall off

Must cut off air supply during maintenance or adjustment

Do not exceed maximum working pressure to avoid equipment damage

Ensure fingers are correctly fixed during installation to prevent loosening during operation

5. Troubleshooting

Common Problems and Solutions:

Gripper Does Not Move

Check if air source pressure is normal

Confirm if air pipe connections are correct and free from leaks

Check if there are foreign objects stuck inside the cylinder

Insufficient Clamping Force

Check if working pressure meets requirements

Confirm if workpiece weight is within the gripper's rated range

Check if piston seals are worn

Fingers Not Moving Parallelly

Check if linear guide has foreign objects or damage

Confirm if installation is correct and free from tilting

Check if transmission mechanism is worn or loose

Decreased Repeatability

Check if linear guide is worn

Confirm if mounting surface is flat

Check if working pressure is stable

Abnormal Noise

Check lubrication condition, add lubricating oil if necessary

Confirm if installation is secure and free from looseness

Check if moving parts are worn or damaged

Maintenance Recommendations:

If the fault cannot be resolved independently, please contact WENK Pneumatic technical support

Regularly check wear conditions of key components and replace wearing parts timely

Professional technical personnel are recommended for maintenance work

Original accessories are recommended when replacing parts to ensure compatibility and performance
