PZP - 3 finger self-centering
PZP - 3 finger self-centering
The 3-finger self-centering pneumatic gripper series PZP operates within a pressure range of 2-8 bar and a temperature range of -10°C to 90°C, extendable to 130°C upon request. It features wedge-hook kinematics, with housing made from high tensile hard-coated aluminium alloy and functional parts from treated ground steel. The grippers are pneumatic, requiring filtered compressed air, and are maintenance-free for up to 1.5 million cycles. They are suitable for both internal and external gripping and have an IP 40 rating, with dust protection available up to IP 64.
The document outlines the PZP series, which includes models ranging from PZP 40 to PZP 300, each with specific dimensions, gripping forces, and operational parameters. Key features include hose-free direct connection and optional features like top jaw blanks and quick-change jaw systems.
Gripping force at 6 bar varies by model, from 255 N for PZP 40 to 25,500 N for PZP 300. Air consumption and gripper weight are specified for each model, along with recommended part weights for transport and maximum finger length and weight.
Minimum operating pressure is 2 bar, with a maximum of 8 bar. Cycle times exclude valve switching and other delays. Transportable weight calculations use a coefficient of friction of 0.1 and a safety factor of 2.
The TDM version enhances gripping forces with an additional piston mechanism, achieving full force after several hundred cycles. It can include a force maintenance device for both closing and opening.
Options include dust protection, precision versions, and a spring-loaded pressure piece for workpiece positioning. Mounting kits for sensors are available for end position monitoring.
- PZP Series: Models include PZP 50 to PZP 300, with gripping force specified at 6 bar and variations based on finger length.
- Quick-Change Jaw System (TY): Allows rapid manual exchange of top jaws with form-fit locking and high replacement accuracy.
- Universal Intermediate Jaw (JUS): Enables tool-free adjustment and fast exchange of top jaws, made from anodized aluminum alloy.
- Ensure locking surfaces are grease and oil-free.
- Adhere to maximum permissible finger length and load values.
- Reduce air pressure if maximum finger weight is exceeded to prevent issues during jaw movement.
- TY System: Dimensions, weight, maximum force, and torque for each type (TY 50 to TY 300).
- JUS System: Dimensions, grid stroke, weight, maximum force, and torque for each type (JUS 40 to JUS 200).
- Material Specifications: Intermediate jaws are made from high tensile aluminum alloy, with options for steel or aluminum.
