| Zusammenfassung: | The invention discloses an engine valve head multi-positioning combined machining method. The method is applied to a machining lathe and comprises the steps of main positioning of the end of a valve rod and clamping of the valve rod; a valve is rotated in the x-axis freedom degree direction, and in the valve rotating process, a valve retainer conical surface is machined for the first time, so that a valve retainer conical surface auxiliary positioning face is obtained; the valve retainer conical surface is positioned through the valve retainer conical surface auxiliary positioning face, and then a valve retainer outer circle, a valve retainer side angle and a valve retainer end face are machined till machining of the valve retainer outer circle, the valve retainer side angle and the valve retainer end face is completed; and the valve retainer side angle is positioned to complete positioning of the valve retainer side angle, and then the valve retainer conical surface is machined for the second time, so that m |
