Driven gear press-fitting machine

The invention discloses a driven gear press-fitting machine, comprising two C shaped upright column racks, main cylinder assemblies, an auxiliary cylinder, movable working platforms, a movable cylinder, a hydraulic system and an electric controlling system; the driven gear press-fitting machine is characterized in that the two C shaped upright column racks are connected and juxtaposed by different heights; extension parts on the upper surfaces of the high and the low upright column racks are respectively and internally provided withy a set of main cylinder assembly; elastic pressure head tips are arranged at the ends of cylinder piston rods; the auxiliary cylinder is arranged in a rack pedestal and vertically corresponds to the main cylinder assembly of the high upright column; pedestals of the two C shaped upright column rackracks are provided with two groups of movable working platforms and are connected with the movable cylinder; the two working platforms are horizontally distributed in a staggered manner; and the cylinder which is arranged at the lower ends of the pedestals of the C shaped upright column rackracks and used for measuring is provided with a displacement sensor. According to the driven gear press-fitting machine, the automation degree is high; the entire process of press-fitting and detaching is finished by electric and hydraulic controls; the press-fitting precision is high; by fixing the press-fitting through a central hole, the coaxiality is guaranteed, and the displacement is avoided; and the press-fitting precision is ensured.
