Mounting - Universal Robots UR3/CB3 User Manual

Mount the robot on a sturdy surface strong enough to withstand at least ten times
the full torque of the base joint and at least five times the weight of the robot arm.
Furthermore the surface shall be vibration free.
If the robot is mounted on a linear axis or a moving platform then the acceleration
of the moving mounting base shall be very low. A high acceleration might cause the
robot to stop, thinking it bumped into something.
Tool The robot tool flange has four M6 thread holes for attaching a tool to the robot.
The M6 bolts need to be tightened with 9 N m. If very accurate repositioning of the
tool is desired, the Ø6 hole is provided for use with a pin. Figure 4.2 shows where to
drill holes and mount the screws.
Control Box The control box can be hung on a wall, or it can be placed on the
ground. A clearance of 50 mm on each side is needed for sufficient airflow. Extra
brackets for mounting can be bought.
