The invention discloses a gantry moving milling-boring machine integrating direct-drive motor sliding platform supporting and self locking. The gantry moving milling-boring machine is characterized by comprising double machine bodies, wherein left and right vertical columns of a gantry are respectively arranged on the double machine bodies; a linear motor is arranged between one of the double machine bodies and one of the vertical columns of the gantry, a rotor of the linear motor is connected with the corresponding vertical column of the gantry, a stator of the linear motor is connected with the machine body, machine tool guide rails are arranged on two sides of the linear motor and positioned on the machine body, sliding platforms which are matched with the guide rails are arranged on the vertical columns of the gantry, and self locking devices are arranged on the sliding platforms; the gantry is in a form of moving along an X axis; rams which can move along a Y axis and a Z axis are arranged on a transverse beam of the gantry; and tools are clamped on the rams. The gantry moving milling-boring machine has the advantages that the movement of the gantry of a machine tool and the movement of the rams along the Y axis are directly driven by the linear motor, the movement along the X axis and the Y axis is realized, direct driving of an intermediate transfer mechanism is eliminated, and by using a device integrating the sliding platform supporting and the self locking, high positioning accuracy, high reliability and high rigidity of the machine tool can be more easily realized.
Description
technical field [0001] The invention relates to a gantry mobile milling and boring machine. Background technique [0002] In the existing milling and boring machines, the movement of the ram mainly depends on the servo motor + worm gear or gear or screw drive, which has defects in work reliability and positioning accuracy, which affects work performance. Contents of the invention [0003] The purpose of the present invention is to provide a gantry mobile milling and boring machine with reasonable structure, high positioning accuracy and good working reliability, which integrates the direct drive motor sliding table support and self-locking. [0004] Technical solution of the present invention is: [0005] A gantry mobile milling and boring machine with direct-drive motor sliding table support and self-locking integrated. A linear motor is arranged between them, and the mover of the linear motor is connected to the gantry column, the stator of the linear motor is connecte...
