The Lock-up RCC Device is a device for correcting positional misalignment when robots or other automated assembly equipment are used for insertion tasks. The LUR Series incorporates a pneumatic lockup mechanism in a modified RCC Device which stops lateral vibration of the shaft when the robot arm moves. This allows for greater speed and acceleration in the operation and reduces cycle time, as the robot does not need to wait for the lateral vibration to stop before performing the insertion function.

Guide to Model Selection

Lateral stiffness (KL) and cocking stiffness (RC) are the two most important properties in selecting a suitable device. The values KL and RC required for correct assembly can be determined using the basic principles of dynamics. The following example of the insertion of a shaft into a hole demonstrates the significance of the values KL and RC.

From initial approach to complete insertion of the shaft

Guide to Model Selection

F： Insertion force (kgf)
X：Lateral misalignment (cm)
α：Cocking misalignment (rad)
D：Hole diameter (cm)
d：Shaft diameter (cm)
μ：Coefficient of friction
θ：Chamfer angle (deg)
C：Clearance ratio (D-d)/D

Relationship between insertion force and depth of insertion

※Complete insertion can only be achieved if the selected device has actual values for KL and RC which
   are less than the theoretical values calculated using the equations above.
   Taking this into consideration, as well as other factors such as dimensions and weight, choose the most suitable model
   for your requirement.
