FIPA Expander grippers are available in a mini version, used for secure gripping of the smallest components / within all hollow shapes. The gripper is available in a mini design for handling particularly small work-pieces having an internal diameter of 4.5 to 8.7 mm.
A day that occurs frequently in gripper technology: Uneven injection molding parts made of plastic having various perforations must be removed from the mold. Alternatively, pipes need to be gripped securely. It is particularly for components having hollow openings and those difficult to grip that FIPA offers the Expander pneumatic expansion gripper.
The great benefit of the mini expansion gripper: It works safely even with non-circular openings and can, thus, be used with all hollow shapes. If special caution needs to be exercised for highly sensitive and thin-walled parts the gripping force of the mini expansion gripper can be controlled with the help of the supply pressure as required.
Functionally safe principle of operation
Be it a round borehole, rectangular recess or a slot hole. Where other grippers cannot get a secure grip, the Expander penetrates into the part to be moved, expands uniformly once it is inside by axial compression of the elastomer, and holds the work-piece tight as a result of the force directed outwards. This functionally safe type of gripping finds immense application opportunities in day-to-day production facilities.
More convincing arguments for the cost-conscious: The elastomers that are made of NBR or highly heat-resistant silicone have a long life if they, however, do get worn out, they can be replaced easily and cost-effectively.
