ELECTRIC PRESS MACHINE IT EXACTS, FOR THE ROTATIONAL MOTION BEING CHANGED TO THE LINEAR MOTION AND GUARANTEEING THE MINUTE ASSEMBLY WORK

摘要

PURPOSE: An electric press machine is provided so that it minutes and the pressurizing rod of the electromotive press is linear motion made smoothly and the exact press-fitting task is proceed.;CONSTITUTION: An electric press machine comprises a ball screw(130) and a rotary motion preventing unit which prevents the rotational motion of the ball screw nut in order to relatively move the ball screw nut(140). The rotational motion preventive measure comprises a tie rod(170), a press rod head unit(150), and a body cover(180). The lower part of the tie rod is combined in a flange(190) of frame and the rotational motion of the pressurizing rod head unit is prevented. The tie rod guide member(151) of the pressurizing rod head unit adheres closely to the tie rod to slide. It is integrally combined with the ball screw nut and the pressurizing rod head unit exercises to the straight line. It is combined between the frame flange and motor bracket and the body cover sanctions a distortional stress.;COPYRIGHT KIPO 2010
