Abstract
This disclosure relates to a shrink-fit device for inductively heating shrink-fit chucks for shank tools, having an accommodating region for accommodating a shrink-fit chuck, an induction coil arrangement which surrounds the accommodating region concentrically with respect to a coil axis, and a measuring unit for controlling the temperature of the shrink-fit chuck. For controlling heating, a measuring channel, which opens into the accommodating region, passes through the induction coil arrangement. The measuring unit has a temperature sensor which engages in the measuring channel for detecting a casing temperature of the shrink-fit chuck.
Claims23
A shrink-fit device for inductively heating shrink-fit chucks for shank tools, the device comprising:
- an accommodating region configured to accommodate a shrink-fit chuck;
- an induction coil arrangement surrounding the accommodating region concentrically with respect to a coil axis;
- a measuring channel passing through the induction coil arrangement and opening into the accommodating region;
- and
- a measuring unit configured to control the temperature of the shrink-fit chuck, the measuring unit including a temperature sensor configured for detecting via the measuring channel a casing temperature of the shrink-fit chuck.
A method for inductively heating a shrink-fit chuck in a shrink-fit device, the method comprising:
- placing a shrink-fit chuck into an accommodating region of the shrink-fit device;
- heating an induction coil arrangement that concentrically surrounds the accommodating region and thereby inductively heating the shrink-fit chuck, whereby the shrink-fit chuck thermally expands;
- and
- controlling the temperature of the shrink-fit chuck using a measuring unit in which a casing temperature of the shrink-fit chuck is detected via a measuring channel passing through the induction coil arrangement.
