Expanding pullback clamping module |
摘要 |
A clamping module has a retractable drawbar and pivoting expansion members. The expansion members are pivotable from a first position having an effective diameter which is less than the minimum diameter of the workpiece hole through which the drawbar and expansion members are extended and a second position engaging the workpiece so as to transmit an axial force from the drawbar through the expansion members to the workpiece sufficient to secure the workpiece.
