    • In a machine tool of the present invention, a spindle head rotatably supports a vertical tool spindle. On the spindle head base, a guide mechanism is provided so as to guide the spindle head in mutually orthogonal first and second horizontal directions and in a vertical direction. A workpiece is supported on a workpiece supporting base provided at a front side of the spindle head base. The workpiece is surrounded with a side cover assembly on the workpiece support base so as to define a machining area therewithin. The upper end of the side cover assembly is covered with a top cover assembly. The top cover assembly has a spindle hole through which a nose portion of the spindle head passes so as to permit the tool spindle to reach the machining area, and is flexibly operable to follow the movements of the spindle head in the first and second horizontal directions.
    • 在本发明的机床中,主轴头可旋转地支撑垂直工具主轴。 在主轴头基座上设有引导机构,以便将主轴头沿相互正交的第一和第二水平方向以及垂直方向引导。 工件被支撑在设置在主轴头基座的前侧的工件支撑基座上。 工件被工件支撑基座上的侧盖组件围绕,以便在其中限定加工区域。 侧盖组件的上端被顶盖组件覆盖。 顶盖组件具有主轴孔,主轴头部的鼻部通过该主轴孔,以允许工具主轴到达加工区域,并且可灵活地操作以跟随主轴头在第一和第二水平方向上的移动 。

    • A pallet exchange apparatus has a bed and an arm assembly supported on the bed to be rotatable between a workpiece loading-and-unloading station and workpiece machining station. A pair of cylindrical holes are formed at both ends of the arm assembly for receiving the pallets. The apparatus is further provided with driving means for rotating the arm assembly, a turntable rotatably mounted on the bed at a position corresponding to the workpiece machining station, first engagement portions formed at the ends of the arm assembly, second engagement portions formed on the pallets so as to be engaged with the first engagement portions for preventing the rotation of the pallets, and a moving device disposed on the turntable for moving the pallet located at the workpiece machining station in the vertical direction. When the pallet is lowered by the moving device, the pallet is separated from the turntable and the second engagement portion of the pallet is engaged with the first engagement portion. When the pallet is raised, the pallet is thrust against the turntable and the second engagement portion is disengaged from the second engagement portion.
    • 托盘交换装置具有床和臂组件,其支撑在床上以在工件装载站和工件加工站之间旋转。 在臂组件的两端形成一对圆柱形的孔,用于接收托盘。 该装置还设置有用于使臂组件旋转的驱动装置,可转动地安装在床上的与工件加工台相对应的位置的转盘,形成在臂组件端部的第一接合部分,形成在托盘上的第二接合部 以便与用于防止托盘旋转的第一接合部分接合,以及设置在转台上用于沿垂直方向移动位于工件加工站的托盘的移动装置。 当托盘被移动装置降低时,托盘与转台分离,托盘的第二接合部分与第一接合部分接合。 当托盘升起时,托盘被推靠在转盘上,第二接合部分从第二接合部分脱离。
