    • In a vertical machining center, a spindle-drive sleeve is axially immovable in the machine frame, but rotates about its longitudinal axis to rotate a spindle mounted in the sleeve for rotation by the sleeve while axially slidable independent of the sleeve. A linear drive, non-rotating ball screw connected to the upper end of the spindle is driven axially by a rotationally powered, axially anchored ball nut to advance and retract the spindle in the sleeve. A drawbar coupling system extends inside the spindle from the top to the bottom to connect to any one of various toolholders in an index disk which is rotatable for positioning toolholders sequentially in line with the spindle axis. A pneumatically actuated drawbar operator shaft extends inside and coaxially with the ball screw from the top to the bottom. The shaft actuator is mounted to the top of the ball screw and drives the shaft axially inside the screw when a toolholder is to be approached for connection. Axial movement of the spindle by rotation of the ball nut in one rotational direction places the spindle in position for coupling to a toolholder in the index disk. Deactivation of the actuator enables a spring to secure a set of gripping fingers in the spindle onto the toolholder.
    • 在垂直加工中心中,主轴驱动套筒在机架中轴向不可移动,但绕其纵向轴线旋转,以使安装在套筒中的主轴旋转,以便套筒旋转,同时可独立于套筒轴向滑动。 连接到主轴上端的直线驱动非旋转滚珠丝杠由旋转动力的轴向固定的滚珠螺母轴向驱动,以推动和缩回套筒中的主轴。 牵引杆联接系统从主轴到底部延伸到主轴内部,以连接到分度盘中的各个刀柄中的任何一个,其可旋转以与主轴轴线顺序地定位。 气动牵引杆操作杆从滚珠丝杠的顶部向下延伸到内部并与滚珠丝杆同轴。 轴致动器安装到滚珠丝杠的顶部,并且当要夹持刀架以进行连接时,可以在螺钉内轴向驱动轴。 主轴通过滚珠螺母在一个旋转方向上的旋转的轴向运动将主轴放置在适当位置,以便联接到索引盘中的刀夹。 执行器的停用使得弹簧能够将主轴中的一组夹持指固定到刀架上。

    • A machine tool control simulator for a machine tool control having a plurality of first user-actuatable devices and a first display screen is disclosed. The machine tool control simulator may include a console and a laptop computer. The console may include a plurality of second user-actuatable devices each corresponding to a respective one of the first user-actuatable devices, and having a layout substantially similar to a layout of the first user-actuatable devices. The laptop computer includes a keyboard and an attached second display screen. The keyboard may be placed between a tabletop and the second user-actuatable devices. The computer receives user inputs from the second user actuatable devices and displays images on the second display screen to simulate images that would be displayed on the first display screen of the machine tool control in response to the user inputs.
    • 公开了一种用于具有多个第一用户可致动装置和第一显示屏的机床控制的机床控制模拟器。 机床控制模拟器可以包括控制台和膝上型计算机。 控制台可以包括多个第二用户致动装置,每个第二用户可致动装置对应于第一用户可致动装置中的相应一个,并且具有基本上类似于第一用户可致动装置的布局的布局。 膝上型计算机包括键盘和附接的第二显示屏。 键盘可以放置在桌面和第二用户可启动装置之间。 计算机接收来自第二用户可启动装置的用户输入,并在第二显示屏幕上显示图像,以模拟将响应于用户输入显示在机床控制的第一显示屏幕上的图像。
