2. Product Overview
The Tool Changer provides flexibility to robot applications by allowing the robot to change customer tooling (e.g.,
grippers, vacuum cup tooling, pneumatic and electric motors, weld guns, etc.) automatically. The Tool Changer
consists of a Master plate and a Tool plate. The Master plate is attached to a robot, while end-effectors such as
grippers, material handlers, etc. are attached to one or more Tool plates.
The Master plate locks to the Tool plate with a pneumatically driven locking mechanism. This locking mechanism
uses a patented, multi-tapered cam with ball locking technology and a patented fail-safe mechanism.
The robot can be programmed to select the desired customer tooling by coupling the Master plate to the Tool plate
attached to the tooling. Electrical signals, pneumatic power, and fluids can be transferred to the customer tooling
through the Master plate and Tool plate by optional modules. See the respective manuals for these options for more
details.

Notes: QC-150 Tool Changer Master and Tool plate assemblies with (-B and -E) part numbers have black anodized bodies
2.1 Master Plate Assembly
The Master plate assembly includes an anodized aluminum body, a hardened stainless-steel locking
mechanism, and hardened steel alignment pins. The locking mechanism consists of a cam, a male coupling,
and chrome-steel ball bearings. The Master plate provides (2) flats for mounting optional modules.

Air Connection
The air port provides lock and unlock air for the locking mechanism and pass through air for the end of arm
tooling.
Alignment pins on the Master mate with bushings on the Tool to ensure repeatable alignment during the
coupling process. An extreme pressure grease is applied to the cam, male coupling, ball bearings, and pins to
maximize the life of the Master plate assembly.
A cover plate attaches to the Master to protect the internal locking mechanism during shipment. This cover
plate can be removed during installation, if replaced by an interface plate or Sensor interface plate. Refer to
for details.
