WARNING: TOPPLE INJURY HAZARD
The robot's center of mass can cause the robot to fall over if the robot is
not secured with the mounting bolts.
NOTE:
Check the mounting bolts one week after initial installation, and then
recheck every 6 months. See Maintenance on page 111 for periodic maintenance.
3.3 Install the Tool Flange
This section provides information to install the tool flange.
The tool flange, which you mount on the robot's quill, is the attachment point for all external
tooling and end-effectors that allow the robot to perform work.
To ensure proper tool flange alignment with the grooves on the quill, there is a setscrew on the
flange that holds the rotational position of the flange on the quill shaft (refer to the following
figure). A steel ball behind the setscrew contacts the shaft in one of the quill's vertical-spline
grooves to keep the flange aligned.
Additional Information
: For flange dimensions, hole pattern, and location of
flange ground point, refer to Tool Flange Dimensions on page 149.
