1.1 Master Plate Assembly
The Master plate assembly includes an anodized aluminum body, a hardened stainless steel locking
mechanism, and hardened steel alignment pins (see
).
The body or Master plate has (6) flat sides for mounting of optional modules. In general, flat ‘A’ is reserved
for an air/valve adapter module and a control/signal module. Flats “B1”, “B2”, “C”, “D1”, and “D2”
are fully interchangeable and optional modules can be arranged to suit the application or robot dress, as
required.
The locking mechanism consists of a cam, a male coupling, and chrome steel ball bearings.
Tapered pins located on the Master plate mate with bushings in the Tool plate to ensure repeatable alignment
during the coupling process. An extreme pressure grease is applied to the cam, male coupling, ball bearings,
and pins to enhance performance and maximize the life of the Master plate assembly.
Proximity sensors are designed into the body of the Master plate to verify the lock/unlock position of the
piston and cam. The sensors provide the lock and unlock (L/U) signals through the control/signal module.
Proximity sensor assemblies are mounted to the body of the Master plate to verify Tool plate presence when
coupled. The sensors provide a ready‑to‑lock (RTL) signal through the control/signal module.
A mounting pattern is machined into the Master plate for mounting to a robot arm or a interface plate. Refer
to
for details.
