摘要： A spade drill characterized in that the slotted blade clamping end of the holder has non-symmetrical oppositely disposed blade clamping faces, each of which extends close to the cutting end and cutting diameter of the blade on the side of the blade opposite to the side containing one cutting edge thus to provide firm support for said one cutting edge and is beveled at its end to provide a wide divergent passage for free passage of chips from the other cutting edge to the longitudinal obtuse angle groove of the holder which intersects such divergent passage at its wide end.

摘要： An overload detection mechanism for a robot is disclosed, wherein first and second members are relatively urged together by an urging means to urge the axis of the second member toward the Z axis of the first member. The second member is guided in any movements departing from coaxial alignment, and the first member is supported near the end of a robot arm. A tool mount or workpiece mount is connected to the second member. An electrical device is mounted on one of the members, and a device actuator on the other of the members, with the reaction means acting between the members to relatively move the members upon tilting from an X-Y plane normal to the Z axis, or axial thrust applied by the tool mount to the second member. In this manner, an overload of a tool in the tool mount establishes relative movement between the first and second members, so that the electrical device is actuated to change an electrical condition thereof and can be connected to stop movement of the robot.
摘要翻译：公开了一种用于机器人的过载检测机构，其中第一和第二构件通过推动装置相对地推动在一起，以将第二构件的轴线朝向第一构件的Z轴推动。第二构件在离开同轴对准的任何运动中被引导，并且第一构件被支撑在机器人手臂的端部附近。工具安装件或工件安装件连接到第二构件。电气设备安装在其中一个构件上，另一个构件上安装有一个装置致动器，反作用装置作用在构件之间，以便在垂直于Z轴的XY平面倾斜时相对移动构件，或轴向推力通过工具安装件施加到第二构件。以这种方式，工具架中的工具的过载建立了第一和第二构件之间的相对运动，使得电气装置被致动以改变其电气状态并且可以被连接以停止机器人的运动。

摘要： An adjustable insert cartridge is described in which a toolholder shank is threadedly engaged in a threaded adjusting sleeve having a flange with a rearwardly facing face. The rearwardly facing face is in rotatable sliding engagement with a forwardly facing face on a mounting collar which is attached to a boring bar. The rearwardly and forwardly facing faces are held in abutment by a spring which is compressed between a rear face of the mounting collar and an adjusting ring threadedly engaged on the adjusting sleeve.
摘要翻译：描述了一种可调整的插入盒，其中刀夹柄螺纹地接合在带有向后表面的凸缘的螺纹调节套筒中。面向后面的表面与安装套环上的面向前的面可旋转地滑动接合，所述安装套环附接到镗杆。向后和向前的面通过弹簧保持抵靠，该弹簧在安装轴环的后表面与螺纹接合在调节套筒上的调节环之间被压缩。
