Abstract

A vertical turning-milling complex machining center comprises a horizontally-arranged bed body (6) and a vertically-arranged column (7). The bed body (6) is provided with an X-axis lateral supporting linear track (2) and an X-axis guide screw (5). The bed body (6) is also provided with a uniaxial rotating table (1) which can reciprocate and is driven directly by a first external rotor torque motor. The column (7) is vertically provided with a Z-axis lateral supporting linear track (10), a Z-axis guide screw (9) and a crossbeam (11) that reciprocates up and down. The crossbeam (11) is provided with a transverse Y-axis linear track (13), a Y-axis guide screw (12) and a single-pendulum milling head seat frame that can reciprocate along the Y-axis guide screw (12). The single-pendulum milling head is driven directly by a second external rotor torque motor. The vertical turning-milling complex machining center uses direct-drive technology applied to a B-axis and a C-axis, the motor torque is greatly increased and functional parts can stably operate, therefore the integral rigidity and stability of the machining center are improved.
