摘要： A tool holding device for holding a tool bit to a drive spindle (223) includes a body member (225) having an axially extending bore defined therein for receipt of a tool shank. The body member includes a plurality of axially extending segments (243) defining the bore. The segments (243) are defined by axially extending slits (244) in the body member (225). The slits (244) extend from a front face of the body member rearward. The segments are radially compressible to grip upon a tool shank inserted into the bore when a radially compressive force is applied to the segments (243) in the area of the slits (244). The bore defined by the segments (243) has a tapered diameter that is greater at the front face of the body member and tapers to a lesser diameter in the axially rearward direction.
摘要翻译：用于将工具头保持在驱动轴（223）上的工具保持装置包括主体构件（225），其具有限定在其中的用于接收工具柄的轴向延伸的孔。主体构件包括限定孔的多个轴向延伸段（243）。所述段（243）由主体构件（225）中的轴向延伸狭缝（244）限定。狭缝（244）从本体构件的前表面向后延伸。当径向压缩力施加到狭缝（244）的区域中的段（243）时，段可径向压缩以夹紧在插入孔中的工具柄上。由段（243）限定的孔具有在主体构件的前表面处更大的锥形直径，并且在轴向向后方向上逐渐变细至较小直径。

摘要： A quick release chuck device has a body member defining an axially extending bore for receipt of a tool shank. At least a portion of the bore is defined by a plurality of radially compressible and axially extending gripping segments. The gripping segments are equally spaced and defined by axial slots extending from a front face of the body member. At least two axially extending and aligned recesses are defined on each of the gripping segments. An operating member is coaxial with and surrounds at least the gripping segments of the body member. The operating member defines a varying radial width channel with the recesses formed on the outside of the gripping segments. The operating member is axially movable relative to the body member. Actuating elements, such as balls, are disposed within the varying radial width channels. The actuating elements are movable within the channels by axial movement of the sleeve member from a gripping position wherein the balls are in a reduced radial width section of the channels causing the gripping segments to compress radially inward, and a release position wherein the balls move into a greater radial width section of the channels allowing radial expansion of the gripping segments.
摘要翻译：快速释放卡盘装置具有限定用于接收工具柄的轴向延伸的孔的主体构件。孔的至少一部分由多个可径向压缩且轴向延伸的夹持段限定。夹持段由从主体构件的前表面延伸的轴向狭槽间隔开并限定。至少两个轴向延伸和对齐的凹部限定在每个夹紧段上。操作构件与身体构件的至少夹持段同轴并且至少围绕身体构件的夹持段。操作构件限定了形成在夹持段的外侧上的凹部的变化的径向宽度通道。操作构件可相对于主体构件轴向移动。诸如球的致动元件设置在变化的径向宽度通道内。致动元件可以在通道内通过套筒构件从夹紧位置的轴向移动而移动，其中球处于通道的减小的径向宽度部分中，使得抓握段径向向内压缩，并且释放位置，其中球移动到通道的较大的径向宽度部分允许夹持段的径向膨胀。

摘要： This invention has as its purpose the provision of a clamp screw in which the loss of clamping force is greatly reduced, a powerful clamping force can be obtained with a small rotational input, a sufficient clamping force can be obtained by a manual operation, and moreover, a sufficient clamping force can be obtained without excessive clamping by making effective use of the reverse thrust of the rotating tool. With the clamp screw of the invention, when the flange ring is in contact with the object to be attached, the rotation of the threaded member stops and a clamping state is entered, the rotation of the operating ring is screw fed by the balls moving around the thread grooves, and as a result of this movement of the operating ring due to the screw feed, pressure is exerted on the flange ring through the restraining ring thus clamping the tool to be attached.

摘要翻译：本发明的目的在于提供夹紧力大大降低的夹紧螺钉，通过小的旋转输入能够获得强大的夹持力，通过手动操作可获得足够的夹紧力，而且通过有效地利用旋转工具的反向推力，可以获得足够的夹紧力而无需过度的夹紧。利用本发明的夹紧螺钉，当凸缘环与待附接的物体接触时，螺纹构件的旋转停止并且进入夹紧状态，操作环的旋转由围绕着球的螺旋进给螺纹槽，并且由于螺旋进给而使操作环移动的结果，压力通过限制环施加在凸缘环上，从而夹紧待附接的工具。
