Multiple clamping devices for hydraulic clamping devices with mechanical operation
We manufacture multiple clamping devices with mechanically and hydraulically actuated clamping devices arranged around an indexing table. In the clamping fixture shown here, eight clamping devices surround a round baseplate, and pneumatic or hydraulic connections are not required. The individual clamping devices are equipped with plate spring clamping.
The plate springs press the clamping sleeve forwards so that the axially stationary drawback collet is closed. The collet is secured against distortion with a pin. The collet is unclamped by a mechanically operated piston. The piston housing contains oil that moves the clamping sleeve to the back when the mechanical piston is actuated. This means that the clamping device is self-retaining and a hydraulic connection is unnecessary.
To mount the collet, the clamping sleeve has to be in its rear position, that is, the position in which the collet is opened. Then the collet can be pushed inside the clamping sleeve. Here attention has to be paid to the location where the distortion protection has been mounted. After this, the key is used to draw the collet to the end stop. 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.
