Understand the role of the locking pins in the gripper’s mechanical setup
Context
This article explains the purpose of the two parallel locking pins included with Robotiq’s 2F85 and 2F140 adaptive grippers. These components are often overlooked but can be essential in certain use cases where mechanical stability is critical.
1. Purpose of the Locking Pins
-
The 2F85 and 2F140 grippers are designed with adaptive fingers that conform to a variety of part shapes.
-
The two parallel locking pins allow users to mechanically lock the fingers into a parallel configuration.
-
This locking ensures the fingers move symmetrically and stay parallel throughout the opening/closing motion.
-
Ideal for applications that require high precision or symmetrical gripping forces.
2. When to Use the Locking Pins
-
Use the pins when you need to:
-
Ensure parallel closing on flat or symmetrical parts
-
Avoid any adaptive or angled movement
-
Improve repeatability in high-precision tasks
-
-
Common in collaborative machine tending, bin picking, or tight-fitting part handling.
3. How to Install the Pins
-
Locate the designated holes on each gripper finger.
-
Insert the pins to lock the finger linkages in place.
-
Screw the two M3 screw on it by using the key.
4. Ordering Information
-
The locking pins are sold as a kit.
