Abstract: A tool assembly includes a support body, a clamping device, and a tool holder clamped in a groove of the support body. A stopper block is disposed in the groove and abuts against the tool holder for positioning the tool holder along an axis. The stopper block is held in place by a wedge-type stopper clamp which applies a clamping force to the stopper block in a direction transversely of the axis. A wedge-type holder clamp is provided for applying a clamping force to the tool holder in a direction transversely of the axis. The stopper clamp is secured to the support body by a single fastening bolt, and the holder clamp is attached to the support body by a single fastening bolt. Each of the fastening bolts is provided with a part that forcefully pushes the respective clamp away from the support body in response to loosening of the fastening bolt. The arrangement is such that the tool holder can be inserted and removed without completely removing the holder clamp or its fastening bolt.

Abstract translation: 工具组件包括支撑体，夹紧装置和夹持在支撑体的凹槽中的工具夹具。 止动块设置在凹槽中并抵靠刀架以沿着轴线定位刀架。 止动块通过楔形止动器夹具保持在适当的位置，该止动器夹具沿横向于轴线的方向向止动块施加夹紧力。 提供了楔形夹持器夹具，用于沿横向于该轴线的方向向夹具施加夹紧力。 止动器夹具通过单个紧固螺栓固定到支撑体上，并且夹具夹具通过单个紧固螺栓附接到支撑体。 每个紧固螺栓设置有一个部件，其响应于紧固螺栓的松动而强制地将相应的夹具远离支撑体推动。 该布置使得可以插入和移除工具夹，而不必完全移除夹具夹或其紧固螺栓。
