변속기 다부품 유연 압입 공법 개발

In this paper, a press-fit machine using a robot with servo press is proposed to change an existing press-fit machine for flexible manufacturing line. The existing machine carries out a process at a station but the new developed machine can conduct two processes and is more flexible by using a Robot because positions where parts are pressed can be freely changed. To develop this machine, centering device is used for correcting centers of the parts. The centering device has a function of locking to prevent the oscillation of the parts during moving. The locking function can prevent the extension of cycle time. Also, frame for supporting tons of repulsive force during pressing-fit is used. The frame is a plate made of steel and contact with the bracket of servo press and transfer the repulsive force to base plate fixed at floor. As a test result, the quality of press fit with bearing race and dowel pin is very good. The flexible press fit machine can be applied to parts such as plug, steel ball in engine assembly line..
