2.4 Tool-Grip
®
with holding function
These tool-grippers are especially designed for even faster
changeovers. The already released tool is held safely in the spindle
with a defined force till the tool changer pulls the tool out of the
spindle.
Function:
By replacing the standard tool-gripper by a tool-gripper with holding function (p.11) faster
changeovers are possible.
Connection dimensions and the stroke are the same to the standard version. During the release of
the draw-bolt pushes the tool-holder 0.2 +0,2 mm out of the taper of the spindle. The tool-holder is
held on the 30° shoulder by clamping segments with small slots in a distance of 0,5 - 0,6mm to the
front plane surface of the spindle. When the tool-holder is pulled out by the tool-changer, the
clamping segments with the slots act as a spring with adjustable holding force. When the tool-
changer pushes a tool-holder in the spindle, the clamping segments were compressed and hold
the tool-holder on the 30°-shoulder in a distance of 0,5 - 0,6 mm to the front plane surface of the
spindle.
Your benefit:
-
Faster changeovers due to holding function
-
Simply replace the standard tool-gripper with same installation dimensions
-
Tool-grippers with different holding forces on demand
Technical advices:
-
Blow-out air: Force which occurs by blow-out air has to be lower than the holding force
-
Tool-weight: Limiting the tool weight is strongly recommended
-
Release velocity: To ensure a safe tool-holding, decreasing of the release velocity can be
necessary.
