Pneumatic gripper with 2 concentric fingers
Finger self-locking closed gripper (toggle joint action)
Elastic absorption at opening
Options :
Inductive sensors
Opening screw limitation
Fingers with smooth holes
Interest of 180 ° angle grippers
Grippers with 180° opening angle are generally used to suppress a clearance movement because the open fingers allow the product to pass laterally, for example during a linear transfer or for maintaining a product on a turntable.
Self-locking on closing by toggle effect
These grippers use toggle technology that allows self-locking of the jaws in the last degree of closure and a large clamping force. They therefore remain locked even in the absence of air pressure. They can only be used for a grip from outside the piece and for parts with an identical grip dimension.
The detection cam mounted on the axis of rotation allows the 2 inductive sensors to detect any desired position.
The option “opening screw limitation” allows to adjust the opening stroke if the 180 ° are not sought (the interest to stay on this gripper is to keep the self-locking when closing and the significant tightening force). Without limiting screws, the grippers have an elastic damping at opening.
