Detection device for coaxiality between spindle hole and large oil seal hole of diesel engine body

Abstract

The invention discloses a detection device for the coaxiality between spindle hole and a large oil seal hole of a diesel engine body. The detection device comprises a center shaft whose internal is ofa hollow structure, a circular hollow plate is welded to one end of the center shaft, a nut is fixedly mounted in the center shaft via a mount, a screw is welded to the internal of the nut, the center shaft penetrates one end of the screw, a first spring is welded to one inner side of the circular hollow plate, a projection is welded to the other end of the first spring, the circular hollow plateis provided with a through hole corresponding to the projection, and four groups of first gaps are formed in the side, close to the first spring, of the projection. The screw and the first pole are additionally arranged so that the center shaft can be fixed in the spindle holes of different apertures of the diesel engine, a telescopic pipes, a second pole and a movable block are used cooperatively, so that the coaxiality between the spindle hole and the large oil seal hole of the diesel engine can be detected.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a coaxiality detection device for a main shaft hole of a diesel engine body and a large oil seal hole. Background technique [0002] A diesel engine is an engine that burns diesel to obtain energy release. The advantages of a diesel engine are large torque and good economic performance. The working process of a diesel engine has many similarities with a gasoline engine. Each working cycle also undergoes intake, compression, and work. , Exhaust four strokes, but because the fuel used in the diesel engine is diesel, its viscosity is higher than that of gasoline, it is not easy to evaporate, but its self-ignition temperature is lower than that of gasoline, so the formation of combustible mixture and the way of ignition are different from those of gasoline engines , the main difference is that the mixture in the cylinder of the diesel engine is compression-ignited instead of i...

Problems solved by technology

[0003] When installing a large oil seal hole on the main shaft hole of the diesel engine, if the main shaft hole of the diesel engine and the large oil seal hole are not located on the same center line, it is easy to cause oil leakage. In order to avoid this situation, it is necessary to
