摘要： A single power tool changing device of a CNC machining center includes a tool magazine unit, a cam-based tool changing unit, and a power clutch unit. The tool magazine unit includes a tool magazine body, a rotatable disk, and a plurality of tool sets. The cam-based tool changing unit includes a tool change base, a cam mechanism, and a tool changing mechanism. The power clutch unit includes a first force output axle that drives the tool magazine unit to operate, a second force output axle that drives the cam-based tool changing unit to operate, and a power mechanism, which selectively transmits power to the first or second force output axle. As such, the present invention allows for performance of both operations of tool selection and tool change with a single driving power source so as to achieve an advantage of reducing installation cost.
摘要翻译： CNC加工中心的单个电动工具更换装置包括刀库单元，基于凸轮的换刀单元和动力离合器单元。刀库单元包括刀库主体，可旋转盘和多个刀具组。凸轮式换刀单元包括工具更换底座，凸轮机构和工具更换机构。功率离合器单元包括驱动刀库单元操作的第一力输出轴，驱动基于凸轮的刀具更换单元进行操作的第二力输出轴，以及功率机构，其选择性地将动力传递到第一或第二力输出轴。因此，本发明允许通过单个驱动电源来实现刀具选择和刀具更换的两个操作，以便实现降低安装成本的优点。

摘要： The tool shank contains a taper member, a flange member, a holder member, a clamped member, and a number of slits. The taper member has a conic shape extended along an axial direction with a top section and a bottom section. The flange member is beneath the bottom section of the taper member. The holder member is extended downward from a bottom side of the flange member along the axial direction. The clamped member is extended upward from the top section of the taper member. The slits are configured at intervals around the bottom section surrounding the axial direction. Each slit defines a slightly outwardly bulge. The bulges increase the contact area with and avoid gaps to a tapered socket of a spindle. As such, the tool shank is tightly jointed to the spindle during high-speed rotation without causing vibration and damage.
摘要翻译：工具柄包括锥形构件，凸缘构件，保持构件，夹紧构件和多个狭缝。锥形构件具有沿轴向延伸的锥形，顶部和底部。凸缘构件位于锥形构件的底部下方。保持器构件沿着轴向从凸缘构件的底侧向下延伸。夹紧构件从锥形构件的顶部部分向上延伸。狭缝围绕围绕轴向的底部部分间隔配置。每个狭缝限定一个略微向外的凸起。凸起增加接触面积并避免与主轴的锥形插座的间隙。因此，在高速旋转期间，工具柄与主轴紧密接合，而不会引起振动和损坏。
