Automatic Tool Changer_CRG

Automatic Tool Changer

An automatic tool changer enables an industrial robot to switch between EOAT tools automatically during a production cycle.

Installed between the robot wrist and the end-effector, the system supports fast, repeatable tool changes.

One robot-side unit can work with multiple tool-side units, reducing capital cost and changeover time. CRG tool changers feature a compact, corrosion-resistant design.

Why You Should Choose Us

Reliable Automatic Tool Changing

Safe and Secure

Three independent safety switches provide multiple layers of protection. The design supports reliable operation.

High Precision

High repeatability, verified through extensive lifecycle testing.

High Locking Force

A large-diameter locking piston delivers high locking force.

High Performance

A multi-taper locking mechanism, long-life seals, and high-quality spring contacts ensure secure mechanical and signal connections.

Boost in Productivity

Reduce fixture installation and changeover time to keep production moving.

Easy to Standardize

Standardized interfaces simplify operating procedures and reduce the risk of machine damage, setup errors, and dropped parts.

How the Tool System Works

When a robot must perform multiple tasks, the automatic tool changer quickly connects the required end-effector. It positions and locks each tool securely while automatically connecting pneumatic circuits and electrical signals.

CRG automatic tool changers support payloads up to 500 kg. Current models include QCA05, QCA15, QCA35, QCA50, QCA100, QCA200, QCA-S350, and QCA-S500. QCA-S350 and QCA-S500 options are available for heavy-duty applications, with maximum payloads of 350 kg and 500 kg respectively. The system is lightweight, easy to integrate, highly repeatable, and designed for up to one million cycles.

Selection Guide

How to Choose the Right Robot Tool Changer

A robot tool changer, also called an automatic quick changer, lets one industrial robot use several end-of-arm tools without manual intervention. The right configuration depends on the complete EOAT load, required utilities, cycle demands, and the robot application—not payload alone.

Automatic or Manual Change

Choose an automatic tool changer for programmed, frequent tool changes. For occasional changeovers where an operator can access the cell, a manual tool changer may be the simpler option.

Payload, Moment and Safety

Calculate the total mass of the gripper, workpiece and accessories. Also consider the center of gravity, dynamic moment, emergency-stop loads, locking confirmation and an appropriate safety margin.

Air and Electrical Connections

Confirm how many pneumatic circuits, electrical signals and optional modules the tool requires. CRG can configure robot-side and tool-side assemblies to suit the application interface.

Robot Tool Changer Selection Checklist

These application details help our engineers recommend the correct robot-side, tool-side and utility configuration.

  • Robot brand, model and wrist mounting pattern
  • Total EOAT and workpiece weight
  • Center of gravity and maximum operating moment
  • Required pneumatic ports and operating pressure
  • Electrical signals, sensors and connector type
  • Tool-change frequency and target cycle time
  • Working environment and contamination risks
  • Number of interchangeable tool-side units

For a complete EOAT assembly, the quick changer can be combined with CRG EOAT components, grippers, frame connectors and custom mounting plates.

Common Questions

Automatic Tool Changer FAQ

What is an automatic tool changer for a robot?

It is a coupling installed between the robot wrist and the end-effector. A robot-side unit locks to a compatible tool-side unit and can connect pneumatic circuits and electrical signals during an automated tool change.

How should I size a robotic tool changer?

Start with the combined weight of the EOAT, workpiece and accessories, then check dynamic loads, center of gravity, operating moment and safety margin. Send CRG the robot model and application data for configuration support.

Can one robot use several tool-side units?

Yes. One robot-side unit can work with multiple compatible tool-side units, allowing the same robot to switch between grippers or other EOAT tools within a production cell.

Can CRG customize the mounting and utility connections?

Yes. CRG can evaluate custom mounting plates, pneumatic circuits, electrical connections and EOAT integration based on your robot and application requirements.
