固定布置以及可互换部件和锁定键
摘要：
本发明涉及固定布置以及可互换部件和锁定键，该固定布置用于将可互换部件(1)附连到保持装置(2)。其包括附连到或与可互换部件或保持装置中的一个形成一体的大致圆形轴(7)，以及形成在这两个中的另一个中的大致圆形安装孔(4)，用以防止可互换部件和保持装置相对于彼此旋转的防转装置(9、13)，以及用于将可互换部件和保持装置沿轴的中心轴线(3)的方向朝彼此紧固的致动器(14)。固定布置还包括轴套(17)，该轴套具有沿轴套的中心轴线的方向渐缩的壁厚，使得轴套的外包络面和/或内孔在其中心轴线的方向上为圆锥形，且轴套形成有至少一个狭缝，以及圆锥形部分(4′)，该圆锥形部分形成在安装孔(4)的内周上和/或轴的外周上。
摘要（英）：

The invention relates to a fixation arrangement for attachment of an interchangeable part (1) to a retaining device (2). It comprises a generally circular shaft (7), being attached to or integrated with one of the interchangeable part or the retaining device, and a generally circular mounting hole (4) formed in the other of these two, a rotary preventing means (9, 13) to prevent rotation of the interchangeable part and the retaining device in relation to each other, and an actuator (14) for tightening the interchangeable part and the retaining device towards each other in the direction of a center axis (3) of the shaft. The fixation arrangement also comprises a sleeve (17), which has a wall thickness that is tapering in a direction of a center axis of the sleeve, such that an outer envelope surface and/or an inner bore of the sleeve is conically shaped in the direction of its center axis, and which is formed with at least one slit, as well as a conical portion (4'), which is formed on the inner circumference of the mounting hole (4) and/or on the outer circumference of the shaft. The invention also relates to an interchangeable part as well as a lock key.
