The invention relates to automatic assembling equipment, in particular to automatic assembling equipment for a valve body assembly of a reading valve. The automatic assembling equipment comprises a rotating disc, a first valve body feeding mechanism, a second valve body feeding mechanism, a valve body inner hole outer ring oiling mechanism, a first plastic inner ring feeding mechanism, a second plastic inner ring feeding mechanism, a knurled inner ring feeding mechanism, a valve body closing mechanism, an O-shaped ring feeding mechanism, an O-shaped ring outer ring oiling mechanism and a discharging mechanism, wherein the first valve body feeding mechanism, the second valve body feeding mechanism, the valve body inner hole outer ring oiling mechanism, the first plastic inner ring feeding mechanism, the second plastic inner ring feeding mechanism, the knurled inner ring feeding mechanism, the valve body closing mechanism, the O-shaped ring feeding mechanism, the O-shaped ring outer ringoiling mechanism and the discharging mechanism are sequentially arranged around the rotary disc in the circumferential direction. According to the automatic assembling equipment for the valve body assembly of the reading valve, by arranging a series of assembling mechanisms around the rotary disc, the assembling work of the valve body assembly of the reading valve can be automatically, accuratelyand reliably completed, and the assembling work efficiency is improved.
