Multiple clamping devices with collet clamping attachments hesk in special design
The clamping fixture is a stationary device with a radial arrangement of six collet clamping attachments for standard draw-back collets. The lines for actuating the collet clamping attachment are connected to a rotational feed. The collet clamping attachments are activated hydraulically. Depending on the design of the rotational feed, a single device or several devices simultaneously can be actuated. The movement that clamps and opens the collet is created by means of hydraulic pressure. The collet is stationary in the axial direction and is secured against distortion by means of a slot nut.
To mount the collet, the clamping sleeve must be in the rear position, i.e. the position in which the collet is opened. Then the collet can be pushed into the clamping sleeve. Here attention should be paid to the mounting location of the slot nut. After this, the collet is drawn to the end stop with the key. When mounting or removing the collet, please note that the collet is always relieved, i.e. the clamping sleeve has to be in the rear position in which the collet is opened.
