ABSTRACT:
This invention discloses an automatic pivot pin installation apparatus. It mainly consists of two up and down air-cylinders on different sides of a table base. The upper cylinder puts the steel wire into the position of the mold and a cutter driven by the back side cylinder cuts the wire. Pieces of wires then are pressed down to prearranged installation position of the pivot pin. Then the pins are pushed simultaneously into the pin holes of the object fixed at the central mold of the structure base by means of the lower cylinders of each side.
