Problems solved by technology

However, there is a hidden danger that the O-ring does not completely enter the ring groove. When installing the copper sleeve of the fuel injector, the O-ring is prone to be trimmed; It is easy to push the O-ring over the head, beyond the installation position (ring groove) of the O-ring, or even fall to the bottom of the hole. At this time, the O-ring needs to be taken out and reinstalled, resulting in low assembly efficiency; the O-ring is not complete The hidden danger of entering the ring groove, the O-ring is prone to be trimmed when installing the copper s...

Abstract

The invention discloses a method for installing an in-hole O-shaped seal ring. The method comprises the following steps that firstly, a locating mandrel is arranged, the front end of the locating mandrel is sleeved with the O-shaped seal ring positionably, and the locating mandrel is inserted into an installing hole, so that the O-shaped seal ring corresponds to an installing groove in the installing hole; and then a shifting fork capable of rotating around the cylindrical face of the locating mandrel is inserted into the gap between the locating mandrel and the installing hole, so that an inner ring of the O-shaped seal ring is extruded, thereby entering the installing groove in the installing hole completely, the locating mandrel is taken out, and installing work of the in-hole O-shapedseal ring is completed. A device for installing the in-hole O-shaped seal ring is further provided. According to assembly of the in-hole O-shaped seal ring, direct contact of fingers can be avoided, hand injury is prevented, assembly quality is stable, success is achieved once, and production efficiency is high.

Description

technical field [0001] The invention relates to the field of engine assembly, more specifically, it relates to a method and a device for installing an O-ring in a hole. Background technique [0002] Currently installing O-rings is a manual operation. Put the O-ring on the orifice of the fuel injector first, then use your index finger to push into the hole until it reaches the ring groove, press one side of the O-ring into the ring groove, and then use your index finger to slide along the ring groove Let the O-ring fully enter the ring groove. [0003] Although the cost of the existing installation method is relatively low, there is no tooling cost, and the operation is simple. However, there is a hidden danger that the O-ring does not completely enter the ring groove. When installing the copper sleeve of the fuel injector, the O-ring is prone to be trimmed; It is easy to push the O-ring over the head, beyond the installation position (ring groove) of the O-ring, or even f...
