Product Specifications

Technical details and manufacturing context for Gripper or Fixture

Definition
A gripper or fixture is a critical component within a workpiece handling mechanism that provides secure, repeatable positioning and holding of materials or parts during operations such as machining, assembly, welding, or inspection. It ensures accuracy, safety, and efficiency in automated or manual production lines.
Working Principle
Grippers typically use mechanical, pneumatic, hydraulic, or magnetic force to clamp onto a workpiece. Fixtures are custom-designed structures that locate and restrain a workpiece against locating pins, clamps, or vices to prevent movement during processing forces.
Common Materials
Steel, Aluminum, Engineering Plastics
Technical Parameters
  • Gripping force, stroke length, jaw opening width, repeatability accuracy, and maximum workpiece weight capacity. (mm) Customizable
Components / BOM
  • Jaws/Fingers
    Direct contact surfaces that interface with and grip the workpiece. Often customizable.
    Material: Steel, Aluminum, Polyurethane
  • Actuator
    Provides the mechanical force to open and close the jaws (pneumatic cylinder, electric motor, etc.).
    Material: Steel, Aluminum
  • Body/Housing
    Main structural frame that houses internal components and provides mounting points.
    Material: Aluminum, Steel
Engineering Reasoning
0.5-15 kN gripping force, 0.01-0.1 mm positioning accuracy, -20°C to 80°C ambient temperature
Gripping force exceeds 18 kN causing structural yield, positioning error exceeds 0.15 mm causing misalignment, temperature exceeds 100°C causing polymer degradation
Design Rationale: Von Mises stress exceeding 250 MPa yield strength in aluminum alloy components, thermal expansion coefficient mismatch (23×10⁻⁶/°C aluminum vs 12×10⁻⁶/°C steel) causing binding, polymer seal degradation above glass transition temperature
Risk Mitigation (FMEA)
Trigger Hydraulic pressure surge exceeding 210 bar system rating
Mode: Cylinder seal extrusion and hydraulic fluid leakage
Strategy: Integrate 200 bar pressure relief valve with 10 ms response time
Trigger Cyclic loading at 5 Hz exceeding 10⁷ cycles at 12 kN
Mode: Fatigue crack propagation in jaw linkage pins
Strategy: Implement 4340 steel pins with shot peening to 0.4 mm compressive layer depth

Frequently Asked Questions

What materials are best for grippers in high-temperature applications?

For high-temperature environments, steel grippers are recommended due to their heat resistance and durability. Aluminum can be used for lighter applications with moderate heat, while engineering plastics are suitable for lower temperatures or where corrosion resistance is needed.

How do I choose between a gripper and a fixture for my manufacturing process?

Grippers are typically used for active manipulation and movement of workpieces, often in robotic or automated systems. Fixtures are stationary devices that securely hold workpieces in place during machining or assembly. Choose based on whether you need mobility or fixed positioning.

What maintenance do industrial grippers require?

Regular maintenance includes lubricating actuators, inspecting jaws/fingers for wear, checking body/housing for structural integrity, and ensuring proper alignment. Frequency depends on usage intensity and material handled—steel components generally require less frequent maintenance than aluminum or plastic.

Can I contact factories directly on CNFX?
