Abstract: A rotatable chuck for clamping a shank portion of a rotatably operating machining tool includes a rotatable chuck body provided with a cylindrical bore concentric with a rotation axis of the chuck body. The circumferential surfaces of a clamping portion of the bore are arranged to apply a clamping force around the circumference of the shank portion of the tool when it is mounted in the chuck to fixate the tool in the chuck. The chuck is provided with auxiliary pull out preventing means for preventing inadvertent pull out of the tool in the axial direction of the bore during machining operation, as well as auxiliary rotary preventing means for preventing inadvertent rotation in at least one direction in relation to the chuck during machining operation. The auxiliary pull out and rotary preventing means include an attachment member positionable in an inner portion of the bore and attachable to the shank portion to be clamped, such that the tool and the attachment member will be prevented from being pulled apart in the axial direction and from being rotated in at least one direction in relation to each other.

Abstract: A first coupling part interacts with a second coupling part of a tool coupling. The first coupling part has a first body and a conical pin, which extends from the first body along a center axis (x) to an end surface. The conical pin is insertable into a conical seat. The conical pin comprises a cavity, which extends from the end surface and comprises a number of first protuberances, which are separated and arranged at a distance from each other along a circumferential direction in respect to the center axis so that there are formed a corresponding number of first recesses. The first protuberances form a respective first contact surface and interact with a corresponding number of separated, second contact surfaces of a pull member of the second coupling part. The first contact surfaces form an acute angle with the center axis.

Abstract translation: 第一联接部件与工具联接件的第二联接部件相互作用。 第一联接部分具有第一主体和锥形销，该第一主体和第二主体沿着中心轴线（x）从第一主体延伸到端面。 锥形销可插入锥形座。 锥形销包括从端表面延伸并包括多个第一突起，该多个第一突起沿着相对于中心轴的圆周方向彼此间隔一定距离，使得形成相应的数字 的第一个凹槽。 第一突起形成相应的第一接触表面，并与第二联接部件的拉构件的相应数量的分离的第二接触表面相互作用。 第一接触面与中心轴形成锐角。
