3.1 Master Interface
The Master plate is typically attached to the robot arm. An interface plate can adapt the Master plate to a
specific robot arm. Alignment features (dowel holes and bosses) accurately position and bolt holes secure
the Master plate to the robot arm or an interface plate. Custom interface plates are available from ATI upon
request. (Refer to the Drawing Section for technical information on the mounting features.)
CAUTION:
Do not use more than two alignment features when securing a Master plate
to a robot interface plate. Using more than two alignment features can cause damage
to equipment. Use either two dowel pins or a single dowel pin along with a boss/recess
feature to align the Master plate with the robot interface plate.
CAUTION:
Do not use dowel pins that are too long that will not allow the interface plate
and the Master body’s boss to mate flush with each other. Using dowel pins that are too
long will cause a gap between the interface plate and the Master body’s boss causing
damage to the equipment. Use the proper size dowel pins that will not extend further
than allowed by the Master body.

A gap is between the

and the flange

Note: A dowel pin and a boss/recess
or ((2) dowel pins) are used as
alignment features.
Correct Mounting of the Master Plate
If the customer chooses to design and build an interface plate, consider the following points:
•
The interface plate should include bolt holes for mounting and either (2) dowel pins or (1) dowel pin
and a boss for accurate positioning on the robot and Master plate. The dowel and boss features prevent
unwanted rotation. Refer to the robot manual for robot mounting features.
•
The thickness of the interface plate must be sufficient to provide the necessary thread engagement for
the mounting bolts.
•
Dowel pins must not extend out from the surface of the interface farther than the depth of the dowel
holes in the boss of the Master plate.
•
A recess of proper depth and diameter must be machined into the interface plate to correspond with the
boss on the Master plate.
•
Mounting bolts that are too long can create a gap between the interface plate and the Master plate,
which can damage the equipment.
•
The interface plate must provide rigid mounting to the Master plate.
•
The interface plate design must account clearances required for Tool Changer module attachments
and accessories.
