具有膨胀槽的收缩卡盘
摘要：
本发明涉及具有膨胀槽的收缩卡盘。一个工具卡头(1)具有套段(2)形式的工具容纳体，它具有工具容纳孔(3)，具有与工具卡头(1)的旋转轴线(5)同心的配合面(4)，在其上使符合规定的安装在套段(2)的工具容纳孔(3)里面的工具的柄杆以压配合固定，其中套段(2)从配合面(4)一侧开始具有许多环绕的凹口(6)，其中所述凹口(6)将配合面(4)分成多个相互可比较的、在轴向上基本上自身刚性的配合面分段(4*)，其中这样选择凹口(6)的径向深度(ET)，使得在施加在套段(2)外圆周上的热量的影响下压配合在所有的配合面分段(4*)上基本上均匀地释放。
摘要（英）：

The invention relates to a tool holder (1) comprising a tool receptacle in the form of a sleeve part (2), which comprises a tool receptacle opening (3) comprising a mating surface (4) which is concentric with the axis of rotation (5) of the tool holder (1) and on which the shaft of a tool inserted in accordance with the intended purpose thereof into the tool receptacle opening (3) of the sleeve part (2) can be fixed in a press fit, wherein the sleeve part (2) comprises a number of circumferential recesses (6) from the side of the mating surface (4), wherein the recesses (6) divide the mating surface (4) into several mating surface segments (4*) which are comparable to each other and which are substantially inherently rigid in the axial direction, wherein the radial depth (ET) of the recesses (6); is selected such that the press fit releases substantially uniformly on all mating surface segments (4*) under the influence of heat applied over the outer circumference of the sleeve part (2).
