The invention provides a gantry moving beam type vertical turning-milling combined
machining center. The gantry moving beam type vertical turning-milling combined
machining center is characterized in that a bottom
movement control system i5CNC based on
the Internet condition is in communication with other terminals directly through
the Internet, and an
EtherCAT bus protocol is used for controlling a PLC and motor driving; a vertical turning spindle unit is fixed to the horizontal plane of the front side of a gantry moving beam type frame lathe
bed; a vertical turning spindle is vertically fixed in a vertical turning supporting base, a central
solid chuck is coaxially fixed to the vertical turning spindle, a locking oil cylinder and a pull rod are fixed to the lower end of the vertical turning spindle, and the locking oil cylinder is controlled to drive the pull rod and the central
solid chuck to achieve clamping or loosening; and dual drive is adopted for the Y axis, a spindle
power unit is reversely arranged in a spindle box, a bamboo hat type tool changer is fixed to the rear side of the lathe
bed, and the tool taking function of the spindle is achieved through the X axis, the Y axis and the Z axis. The gantry moving beam type vertical turning-milling combined
machining center has the beneficial effects that one axis is added, both the milling function and the turning function can be integrally achieved in the spindle unit, and high-speed rotating and positioning can be achieved; and a turning tool sliding plate
assembly of the spindle unit is omitted, so that the cost is reduced, and the
cost performance is high. The gantry moving beam type vertical turning-milling combined machining center has better high-and-
low speed properties and dynamic performance.
