The invention proposes a transverse tappet production device. The transverse tappet production device comprises a sizing mechanism, an adjusting mechanism, a drilling and milling mechanism and a painting mechanism; a feed end of the sizing mechanism is communicated with a supply mechanism; transverse tappet blanks are fed in the sizing mechanism by the supply mechanism; the sizing mechanism performs the sizing and cutting treatment for the transverse tappet blanks according to specifications; a discharge end of the sizing mechanism is communicated with the adjusting mechanism; the sizing mechanism feeds the transverse tappet blanks after the sizing and cutting treatment into the adjusting mechanism; the adjusting mechanism performs the direction adjustment for the transverse tappet blanks; a discharge end of the adjusting mechanism is communicated with the drilling and milling mechanism; the adjusting mechanism feeds the transverse tappet blanks after the direction adjustment into the drilling and milling mechanism; the drilling and milling mechanism drills and mills the transverse tappet blanks; a discharge end of the drilling and milling mechanism is communicated with the painting mechanism; the drilling and milling mechanism feeds the drilled and milled transverse tappet blanks into the painting mechanism; and the painting mechanism paints the transverse tappet blanks. The production device realizes automation from sizing to gluing and tenoning of tappets so as to facilitate improvement of the production efficiency.
