Universal Robots UR3e PolyScope X - Mounting Description

Dimensioning the
Stand
Users have the option to incorporate added safety margins, factoring in the following
design considerations:
•
Static stiffness: A stand that is not sufficiently stiff will deflect during robot
motion, resulting in the robot arm not hitting the intended waypoint or path. Lack
of static stiffness can also result in a poor freedrive teaching experience or
protective stops.
•
Dynamic stiffness: If the eigenfrequency of the stand matches the movement
frequency of the robot arm, the entire system can resonate, creating the
impression that the robot arm is vibrating. Lack of dynamic stiffness can also
result in protective stops. The stand should have a minimum resonance
frequency of 45 Hz.
•
Fatigue: The stand shall be dimensioned to match the expected operating
lifetime and load cycles of the complete system.
CAUTION
•
If the robot is mounted on an external axis, the accelerations of
this axis must not be too high. You can let the robot software
compensate for the acceleration of external axes by using the
script command set_base_acceleration()
•
High accelerations might cause the robot to make safety stops.
WARNING
•
Potential for tip-over Hazards.
•
The robot arm's operational loads may cause movable
platforms, such as tables or mobile robots, to tip over, resulting
in possible accidents.
•
Prioritize safety by implementing adequate measures to
prevent the tipping of movable platforms at all times.
5.3. Mounting Description
Description
Robot arm
(Base)
Mounted with four 8.8 strength, 8.5mm bolts and four M8 mounting
holes at the base.
Tool (Tool
Flange)
Uses four M6 thread holes for attaching a tool to the robot. The M6
bolts shall be tightened with 8Nm, strength class 8.8. For accurate tool
repositioning, use a pin in the Ø6 hole provided.
Control
Box
The Control Box can be hung on a wall or placed on the ground.
Teach
Pendant
The Teach Pendant is wall mounted or placed onto the Control Box.
Verify the cable does not cause tripping hazard. You can buy extra
brackets for mounting the Control Box and Teach Pendant.
