摘要： A mechanical press has a ram carried by a frame and movable to advanced and retracted positions by a ball screw assembly driven by a reversible motor to actuate a cam and follower assembly connected to the ram by a linkage system. The linkage system has a pair of pivot links pivotally connected at one end to a fixed pivot shaft connected to the press frame and connected at their opposite end to a follower nut for movement thereby as the follower nut travels along the length of the driven screw. A pair of roller followers are also driven by the follower nut to move between first and second positions within cam tracks formed in a pair of first lever arms operably connected to the ram. In use, when the motor drives the screw in one direction the first lever arms are rotated in one direction to move the ram to its advanced position wherein the ram urges a die or tool into engagement with a workpiece. When the motor is reversed, the first lever arm is rotated in the opposite direction to move the ram to its retracted position to disengage the die or tool from the workpiece.

摘要： A clamp (10) having a pneumatic cylinder (28) with an actuating rod (30) connected to one end of a drive arm (32) which has its other end attached to a crankshaft (19) which in turn has crankpins (20,22) eccentrically mounted thereon to drive inner and outer clamp arms (24,26) between retracted and advanced positions corresponding to open and closed positions of the clamp. The length of the drive arm (32), the extent to which the crankpins (20,22) are offset from the crankshaft (19), the specific portion of a quadrant through which the crankpins are rotated, and the distance between the application of the force to the clamp arms and the axes about which the clamp arms pivot all provide a significant mechanical advantage and an extremely large clamping force from relatively low pressure compressed air supplied to the pneumatic cylinder (28).
摘要翻译：具有气动缸（28）的夹具（10）具有连接到驱动臂（32）的一端的致动杆（30），其另一端连接到曲轴（19），曲轴（19）又具有曲柄销（20， 22），其偏心地安装在其上以在对应于夹具的打开和关闭位置的缩回位置和前进位置之间驱动内部和外部夹紧臂（24,26）。驱动臂（32）的长度，曲柄销（20,22）从曲轴（19）偏移的程度，曲柄销旋转通过的象限的特定部分，以及应用夹紧臂和夹紧臂枢转的所有轴的力提供了显着的机械优点和来自供应到气动缸（28）的相对低压的压缩空气的非常大的夹紧力。

摘要： A line boring apparatus comprising a motorized spindle and tool support mounted on a support frame for motion along two axes perpendicular to a rotational spindle axis. The spindle is also supported for motion along the spindle axis relative to the tool support. A tool cradle is supported beneath the spindle on the support frame and stores boring bars of differing outside diameters equipped with support bushings having outside diameters equal to an inner diameter of the tool support. A CNC is programmed to actuate an axes drive to cause the spindle to select a boring bar and bushing from the cradle. The CNC and axes drive then move the bar and bushing to a predetermined boring position axially aligned with an interrupted line bore to be machined in a workpiece. The CNC then commands the spindle to advance axially toward the tool support, removably engaging the bushing in the tool support and continuing to push the boring bar through the engaged bushing while rotating the bar and boring the interrupted line bore in the workpiece.
摘要翻译：一种线镗孔装置，包括安装在支撑框架上的电动主轴和工具支架，用于沿垂直于旋转主轴轴线的两个轴线运动。主轴也被支撑用于沿着主轴轴线相对于工具支撑件的运动。工具支架支撑在支撑架上的主轴下方，并且存储具有不同外径的镗杆，其具有外径等于工具支撑件内径的支撑衬套。 CNC被编程为启动轴驱动器，使主轴从支架中选择一个镗杆和衬套。然后CNC和轴驱动器将杆和衬套移动到与被加工成工件的中断的线孔轴向对准的预定的镗孔位置。 CNC然后命令主轴轴向前进到工具支撑件，可拆卸地接合工具支撑件中的衬套，并且继续将镗杆推动通过接合的衬套，同时旋转杆并钻削工件中的中断的线孔。

摘要翻译：机械压力机具有由框架承载的柱塞，并且可通过由可逆电动机驱动的滚珠丝杠组件移动到高级和缩回位置，以通过连杆系统致动连接到压头的凸轮和从动组件。连杆系统具有一对枢轴连杆，其一端枢转地连接到固定的枢转轴，该固定枢转轴连接到压力机架上，并且在它们的相对端连接到从动螺母，从而随着从动螺母沿着从动螺杆的长度行进。一对辊跟随器也由从动螺母驱动，以在可操作地连接到压头的一对第一杠杆臂中形成的凸轮轨道内的第一和第二位置之间移动。在使用中，当电动机沿一个方向驱动螺杆时，第一杠杆臂沿一个方向旋转，以将压头移动到其前进位置，其中，该压头迫使模具或工具与工件接合。当电动机反转时，第一杠杆臂沿相反方向旋转，以将压头移动到其缩回位置，以将模具或工具与工件脱离。
