OG...A Two levers toggle gripper
FEATURES:
The OG toggle grippers in this range can clamp the workpiece externally; the levers open fully at the sides and they have been
designed to offer the following advantages:
- the 180° opening permits clamping of the workpiece without a linear approach movement,
- non-reversible clamping, also in the absence of pressure determined by the special toggle mechanism,
- good clamping couple in toggle position (0°)
- the reference marks for fixing of pincers on the levers have been designed to permit simple construction and precise positioning,
- the standard versions have a transversal hole on the levers for the insertion of a pin that allows the optimum adjustment of the toggle clamping point on the workpiece, avoiding the need for correction on the pincers (see diagram)
- mechanism guided throughout the stroke,
- adjustment of opening stoke,
- sturdy construction and the use of top quality materials mean great reliability and little maintenance,
- drilling marks on the gripper body permit precision in side and axial fixing with screws and position monitoring (reed or inductive on request) to avoid increasing its size
Note
To protect the gripper from overloads that may damage the mechanism, the pincers are to be as light in weight as possible and should not exceed the maximum values of moment of inertia md2 indicated for each model in the technical specifications.
Where m = pincer mass in Kg
d = distance from pincer barycentre to lever rotation fulcrum
It is essential to plan for the use of flow regulators that allow optimum regulation of the opening speed according to the specific application.
Optional
External proximity control on the jaws for the use of cylindrical or threaded proximity switches, with brackets and sensor pins.
For these optionals please see the specifications at the end of this family.
