Abstract
The invention discloses a combined lead screw driving device. The combined lead screw driving device comprises an upper cross beam and a base plate. The upper cross beam and the base plate are connected through screws, so that a box is formed. A sliding lead screw penetrates through the middle of the upper cross beam. The bottom of the sliding lead screw is connected with the base plate. Two sets of guide columns and rolling lead screws are arranged and are axially symmetrical relative to the sliding lead screw. The two sets of guide columns and the rolling lead screws are both arranged in a diagonal mode. The sliding lead screw and the two sets of guide columns and rolling lead screws all penetrate through a driving sliding block. The driving sliding block can move up and down along the sliding lead screw. According to the combined lead screw driving device, cooling is conducted in the middle of the sliding lead screw and outside a sliding nut through cooling oil or compressed air, so that overheating of a friction pair is avoided; when an upper die makes contact with a part and starts punching, a servo motor drives a sliding lead screw to rotate, the driving sliding block is driven to move up and down, the rolling lead screws driven by another servo motor can move accordingly simply by being separated from the servo motor due to the fact that the rolling lead screws are not locked automatically, and thus punching is completed; the high bearing capacity of the sliding lead screw can be achieved.
