The ATI Robotic Tool Changer provides the flexibility to automatically change end-effectors or other peripheral tooling. These tool changers are designed to function reliably for millions of cycles at rated load while maintaining extremely high repeatability. For this reason, the ATI Tool Changer has become the number-one tool changer of choice around the world.

ATI Tool Changer models cover a wide range of applications, from very small payloads to heavy payload applications requiring significantly large moment capacity.


What is a Robotic Tool Changer?

Robotic Tool Changer: Component with two mating parts (master and tool) that have been designed to lock together automatically and are able to pass utilities (e.g. electrical signals, pneumatic supply, water, etc.). The master side of the tool changer mounts to a robot, CNC machine or other structure. The tool side of the tool changer mounts to tooling, such as grippers, welders, or deburring tools.  A robotic tool changer is also known as an automatic tool changer, robot tool changer, robot coupler, robotic coupler, and robotic connector.


All ATI Quick Change Tool Changers feature:

Extremely High Repeatability
The unique double-taper locking piston in combination with the two locating pins provides unmatched repeatability. Million-cycle testing, at rated load, shows that the typical repeatability is much better than the guaranteed values.
High Rigidity
The Quick-Change tool changer has a large moment capacity due to the locking piston's high coupling strength and large diameter. The coupled tool changer does not rock during high-inertia moves preventing locking failure or repeatability problems.
Excellent Reliability
The patented double-taper locking mechanism actually wears in instead of out. The pneumatic ports use uniquely-designed, long-life rubber bushings, which prevent any loss of air pressure. Spring probe electrical pins on the Master Plate insure contact with fixed pins on the Tool Plate. The Quick-Change robotic tool changer is built to last.
Superior Fail-safe Locking Mechanism
A new patented locking mechanism locks the Master Plate to the Tool Plate and remains locked even if pressure is accidentally removed.
Lightweight and Compact Design
World-wide sales volumes have allowed us to price the Quick-Change tool changer at or below the competition.
With a wide range of electrical, pneumatic, and fluid modules available, ATI Quick Change Tool Changers can be configured to fit most any application.
