Abstract

The utility model discloses a mounting device of an O-shaped sealing ring of a fuel injector copper bush of an engine cylinder cover. The mounting device comprises a spindle, a guiding bar, an annular sleeve, a shift fork and a conical sleeve. A guiding bar mounting groove is formed in the side wall of the spindle from top to bottom in the axial direction, and a pin annular groove is formed in the upper portion of the spindle in the circumference direction. The annular sleeve is fixed on the guiding bar, an annular gap for the shift fork to move in circumference is formed between the annular sleeve and the spindle, and a circumferential annular rail corresponding to the pin annular groove is arranged on the lower portion of the annular sleeve. The shift fork is in a long strip shape, a pin penetrating hole is formed in the middle-upper portion of the shift fork, and the two ends of a pin penetrating through the pin penetrating hole are located in the pin annular groove of the spindle and the circumferential annular rail of the annular sleeve respectively. The conical sleeve is arranged at the tail end of the spindle in a sleeved mode, and a sealing ring squeezing and correcting conical face is arranged on the upper side wall of the conical sleeve. The mounting device can effectively avoid the potential quality hazards due to the fact that the O-shaped sealing ring does not enter the annular groove completely, prevent edges of the O-shaped ring from being cut and prevent hands from being hurt by sharp burrs on the edge of the annular groove in the operation process, and is stable in assembly quality and high in production efficiency.
