Exchange Gripper/Collet for Nozzle Changers

Product Specifications

Technical details and manufacturing context for Exchange Gripper/Collet

Definition

The Exchange Gripper/Collet is a critical part of a Nozzle Changer system, typically found in automated manufacturing and assembly lines, such as those for electronics, automotive, or precision machinery. Its primary role is to interface directly with the nozzle or tool head. It provides a secure, repeatable grip to facilitate the precise removal of a spent or unsuitable nozzle from a machine spindle and the subsequent installation of a new one. This enables rapid tool changes without manual intervention, minimizing downtime and maintaining production efficiency. The design ensures accurate alignment and clamping force to prevent tool slippage or damage during high-speed operations. The gripper/collet is available in a gripping diameter range of 3–20 mm, with a gripping force of 150–300 N at operating pressures of 0.4–0.8 MPa. Repeatability is ±0.02 mm, ensuring consistent nozzle alignment. Operating temperature range is -10°C to 80°C, above which seals may degrade and below which material brittleness may occur. Ingress protection is IP54–IP65 (IEC 60529), protecting against dust and water jets. The body is made of stainless steel 304 (ASTM A276) for corrosion resistance, and the weight ranges from 0.5–1.2 kg depending on size and configuration. Materials on file include tool steel, hardened alloy steel, and precision bearing steel. These values are directory reference ranges and must be confirmed for the actual model and application. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The gripper/collet operates mechanically, often via pneumatic or servo-electric actuation. A control signal from the nozzle changer's system triggers the actuator. This action either closes the gripper jaws or contracts the collet's internal diameter to clamp firmly onto the specific mating surface (e.g., a shank or groove) of the nozzle. To release the nozzle, the actuator reverses the motion, opening the jaws or expanding the collet. Precision machining and sometimes spring mechanisms ensure the gripping force is consistent and the centering is accurate for reliable tool seating.

Components / BOM

Collet Body / Gripper Jaws
The main structural element that makes direct contact with and clamps onto the nozzle shank.

Material: Hardened Tool Steel
Actuation Mechanism (e.g., Wedge, Taper, Linkage) Part
Converts the input force from the actuator (piston, motor) into the clamping motion of the jaws or collet.

Material: Alloy Steel
Retention Spring Part
Often used in collet designs to assist in returning the collet to its open position when actuation force is released.

Material: Spring Steel
Wear Sleeve/Insert Part
A replaceable liner or insert inside the gripper that contacts the nozzle, protecting the main body from wear and allowing for maintenance.

Material: Carbide or Hardened Steel

Frequently Asked Questions

What is the gripping diameter range of the Exchange Gripper/Collet?

The gripping diameter range is 3–20 mm, as listed in the directory. This is a reference range for standard nozzle shanks; custom sizes may be available. Confirm the exact range for your specific model with the manufacturer.

What operating pressure is required for the gripper/collet?

The operating pressure range is 0.4–0.8 MPa, with a note that below 0.4 MPa gripping force is insufficient. The standard is listed as a reference. Verify the required pressure for your application with the supplier.

What is the repeatability of the gripper/collet?

The repeatability is ±0.02 mm, ensuring consistent nozzle alignment. This value is a directory reference and should be confirmed for the actual model.

What are the temperature limits for the gripper/collet?

The operating temperature range is -10°C to 80°C. Above 80°C, seals may degrade; below -10°C, material brittleness may occur. Always verify these limits with the manufacturer for your specific environment.
