摘要： A coupling mechanism interconnects a rotatable connecting end of a support on a broaching machine and a bit holder which includes a rotary hollow shaft and a mandrel received in the hollow shaft. The coupling mechanism includes a first coupling member that has a first disk part and a first neck part, and a second coupling member that has a second disk part and a second neck part. The first neck part is connected to the connecting end of the support. The first disk part has a plurality of posts projecting axially from the first disk part opposite to the first neck part. The second neck part extends into the hollow shaft for connection with the mandrel. The second disk part has slide holes which extend axially in the second disk part at locations radially outward of the second neck part so as to receive the posts. The second coupling member is guided by the posts and the slide holes for sliding axially relative to the first coupling member. Plural fastening holes extend through the first disk part and the posts. Plural fasteners are disposed in the fastening holes to engage the hollow shaft.

摘要： A device for stabilizing a workstock in a slotted broach tool guide sleeve while a key broach tool extending through the guide sleeve cuts a key slot in the annular bore wall of the workstock. In a preferred embodiment the device is characterized by a pair of top and bottom end plates, each provided with a semicircular notch for receiving the cylindrical guide sleeve at opposite ends of the workstock, after the workstock is positioned on the guide sleeve. Each end plate includes a beveled surface which engages the corresponding open end of the workstock and a plate mount bolt is extended through the end plates and the workstock bore and a nut is threaded on each end of the bolt to secure the end plates against the workstock. The guide sleeve with the assembled device is oriented in a vertical position, with the lower end of the guide sleeve typically secured between the adjacent support plates of a work bench or table and the bottom end plate resting on the work table. As a hydraulic press is operated to extend the key broach tool downwardly through the guide sleeve and workstock to cut a keyway in the annular bore wall of the workstock, the end plates assembled on the guide sleeve prevent lateral displacement of the workstock on the guide sleeve and stabilize the workstock against the cutting edge of the key broach tool. A semicircular keeper can be placed on the work table in engagement with the guide sleeve for stabilizing the key broach tool in the guide sleeve.
摘要翻译：一种用于在开槽的拉刀工具导向套筒中稳定工件的装置，而穿过引导套筒的钥匙拉刀在切割工件的环形孔壁中切割出一个键槽。在一个优选实施例中，该装置的特征在于一对顶端和底端板，每一个顶端和底端板均设置有半圆形槽口，用于在工件被定位在导向套筒上之后，在工件的相对端处接收圆柱形引导套筒。每个端板包括与工件的相应的开口端接合的斜面，并且板安装螺栓延伸穿过端板和工件孔，螺母在螺栓的每一端被螺纹固定，以将端板固定在工件上。具有组装的装置的导向套筒被定向在垂直位置，引导套筒的下端通常固定在工作台或工作台的相邻支撑板之间，底端板搁置在工作台上。当液压机被操作以将钥匙拉刀工具向下延伸穿过引导套筒和工件以切割工件的环形孔壁中的键槽时，组装在引导套筒上的端板防止工件在导向套筒上的横向移位并使工件相对于钥匙刀具的切割边缘稳定。可以将半圆形保持器放置在与导向套筒接合的工作台上，以稳定导向套筒中的钥匙拉刀。
