摘要： A machining system and method of machining are provided for machining large, heavy workpieces, such as large aircraft components, that are oriented vertically affixed on a vertical, on-edge pallet. The machining system includes an upstanding workpiece support to which the transportable pallet is clamped. The pallet is large enough to support the large workpiece but is still relatively thin and light so that it can be easily transported to the machining station where the more massive workpiece support is located. The pallet lacks the necessary stiffness for accurate machining of the part thereon. The much thicker upstanding support is utilized to provide the pallet and affixed part the necessary stiffness when the pallet is clamped thereto, by a magnetic clamping arrangement. The magnetic clamping provides quick assembly and disassembly of the pallet with the support stand thereby decreasing cycle time and increasing production rates. Also, the magnetic clamping makes the pallet strong and rigid like the support stand during the machining operation. The magnets are arranged on the support stand so as to spread out and evenly balance the magnetic attraction force across the backside of the pallet. Registering members on the stand and pallet locate magnetizable areas on the pallet so that they are aligned with corresponding magnets on the stand. A controller fires the magnets in a predetermined sequence to draw the pallet against the magnets for clamping it thereto. The magnets are preferably of the electropermanent type so that they take a charge and do not need continuous power to keep generating the magnetic attraction force so as to keep the pallet clamped thereto during power interruptions.
摘要翻译： 提供了一种加工系统和加工方法，用于加工大型重型工件，如大型飞机部件，其垂直方向定位在垂直的边缘托盘上。 加工系统包括一个直立的工件支架，可移动的托盘被夹紧到该支架上。 托盘足够大以支撑大型工件，但是仍然相对较薄和轻，因此可以方便地将其运送到加工工位，其中位于较大的工件支架上。 托盘缺乏用于精确加工零件的刚性。 通过磁夹紧装置，当托盘被夹紧到其上时，利用更厚的直立支撑件来提供托盘并且将部件固定在其上。 磁性夹具可以快速地将托盘与支撑架组装和拆卸，从而减少循环时间并提高生产率。 此外，磁力夹紧使得托盘在加工操作期间像支撑架坚固和刚性。 磁体布置在支撑架上，以便平展磁铁吸引力跨越托盘的背面。 在支架和托盘上注册成员定位在托盘上的可磁化区域，使其与支架上的相应磁体对齐。 控制器以预定的顺序触发磁体，以将托盘靠在磁体上以将其夹紧到其上。 这些磁体优选地是电绝缘型的，因此它们进行充电并且不需要连续的电力来继续产生磁吸引力，以便在断电期间将托盘夹持在其上。

摘要： A passive lock assembly is suitable for use with a door mounted to a door frame. The passive lock assembly includes a housing, a bolt, an actuator, and a stop member. The housing is mounted on the door. The bolt extends from the housing and is moveable between an extended position and a retracted position. The actuator is supported by the housing and is operably connected to the bolt. Additionally, the actuator is moveable to move the bolt between the extended position and the retracted position. The stop member is pivotably connected to the housing and pivotable between a first position and a second position. In the first position, the stop member engages an engagement surface of the actuator to obstruct movement of the actuator and prevent movement of the bolt to the retracted position, and in the second position, the stop member does not obstruct movement of the actuator.
