We are an experienced developer and manufacturer of mandrel grippers for use on industrial robots.
When using industrial robots for roll manipulation, it is often only possible to work over the core. The following criteria for appropriate clamping tools are decisive:
WISTEC mandrel grippers meet all specified criteria and have been in successful use for years in combination with the different robot types and brands.
In principle, gripper systems with continuous clamping shells Leafs), or clamping wedges (Lugs) are used. If possible impressions on the inner sleeves must be avoided, mandrel grippers with clamping shells are recommended. In order to hold the outer part blanks securely, the shells are designed accordingly.
For higher dynamic loads, gripper systems with clamping wedges are preferred. Here, too, a secure hold of the outer partial rollers can be ensured by increasing the diameter of the clamping elements. This is clearly shown by the next wedges.
Even larger sleeve diameters can be handled with ease
