摘要： A quick change device for mounting a tool in a support member such as a turret. The tool has a shank with radially outwardly movable balls therein and the mounting device includes a sleeve receivable on the shank and adapted for mounting in a bore in the support member. The shank includes an actuator ball causing the aforementioned balls to move radially outwardly and engage a shoulder at the end of the sleeve to pull the tool into a predetermined axial position and lock the tool in the aforementioned position while cooperating elements of key means in the tool in the support member prevent rotation of the tool in the support member.

摘要： A machine tool having an indexable turret in which the turret has a plurality of stations for supporting tools and with the tools in the stations being presented individually to workpiece operating position in a respective indexed position of the turret during a work cycle. At least two of the stations of the turret are provided with identical tools, forming a group, and on each work cycle one of the pair of stations is bypassed thereby providing a reserve tool which can be made effective without interrupting the work cycle of the machine. Advantageously, most of the tools carried by the turret are provided in groups so that substantially a complete set of reserve tools is provided. Each tool can be used for a certain number of work cycles, or the machine can be provided with adaptive, or tool sensing, controls which sense the dulling or breaking of a tool, or workpieces taken from the machine can be periodically guaged to determine when a particular tool has worn down to the allowable limit. The back up or reserve tools can then be called into play, either individually, or as a set. The invention is adapted for use with automatic machines with an automatic arrangement provided for changing from one tool of a group thereof to an identical tool of the same group. In this manner, a machine tool having a turret tooled up according to the present invention can be maintained in operation for a substantially longer period of time than has heretofore been possible thereby increasing production from the machine tool.
摘要翻译： 一种具有可转位转台的机床，其中所述转台具有用于支撑工具的多个工位，并且所述工位中的工具在工作循环期间分别呈现在所述转台的相应的分度位置中的工件操作位置。 转塔中的至少两个工位设置有相同的工具，形成一组，并且在每个工作循环中，旁路一对工位中的一个工位，从而提供一种可以在不中断机器的工作周期的情况下有效的备用工具 。 有利的是，转塔所携带的工具中的大多数工具是以组合的形式提供的，因此提供了大量一整套备用工具。 每个工具可以用于一定数量的工作循环，或者可以为机器提供自适应或工具感测控制，其感测到工具的钝化或断裂，或者可以定期地对从机器取出的工件进行调整以确定何时 特定的工具已经磨损到允许的极限。 然后，备份或预留工具可以单独调用或作为一组调用。 本发明适用于具有自动装置的自动机器，该自动装置用于从其组中的一个工具改变为相同组的相同工具。 以这种方式，具有根据本发明的加工的转塔的机床可以保持在比迄今为止可能更长的时间段的操作中，从而增加了机床的生产。
