Axle lock-up device of press

The utility model provides an intaglio printing machines axis plating devices. The utility model contains two plate-roll installing seats which are fixed on the inside of the press wallboard, a crescent sliding block, and a printing plate-roll which is provided with the roll bearing and the bearing support sleeve. The printing plate-roll is arranged in the crescent sliding block. The rotation of the crescent sliding block is controlled by a cylinder and a cylinder connecting rod, so the printing plate-roll can be quickly installed, fixed, and changed. The intaglio printing machines axis plating devices also contain a horizontal register device which connects to an end of the printing plate-roll, the horizontal register device connects to the sliding block through a small shaft (which is connected with the printing plate-roll) and a horizontal register bearing, the sliding block is parallelly provided with a guiding axle, a roller leading screw, a spring, a worm, and a turbine. The worm driving the turbine, the turbine driving the roller leading screw to rotate, let the sliding block move axially under the guidance of the guiding axle. The horizontal register device process register through the small shaft driving the printing plate-roll for horizontal movement, Thereby the horizontal register of the axis register devices and the gap eliminating is realized, the register precision and printing process requirements are ensured.
