Abrasion loss measurement device for engine valve guide pipe

Abstract

The invention discloses an abrasion loss measurement device for an engine valve guide pipe, belonging to the technical field of engine overhauling. The abrasion loss measurement device comprises a regulation cross rod and a regulation vertical rod, a measurement meter, a fixing base, a vertical regulation sleeve, a V-shaped chuck and a lower regulation mechanism, wherein a telescopic rod sleeve fixing mechanism is matched on the rod body of the regulation cross rod, one end of the regulation cross rod, facing towards the regulation vertical rod, is provided with a regulation vertical rod fixing base, the regulation vertical rod fixing base is clamped on the regulation vertical rod; the measurement meter with a measurement meter telescopic rod is fixed on the telescopic rod sleeve fixing mechanism; the V-shaped chuck is fixed on the end part of the measurement meter telescopic rod; the fixing base is matched on the rod body of the regulation vertical rod; the vertical rod regulation sleeve is connected with the regulation vertical rod; and the lower regulation mechanism is connected with a vertical rod regulation sleeve and is arranged corresponding to the downside of the regulation cross rod. The abrasion loss measurement device has the advantages of ideal adaptability of carrying out indirect measurement on abrasion loss of different modes of cylinder cover valve guide pipes,simple integral structure and convenience for operation, and can be suitable for being applied to various kinds of engine repair departments.

Description

technical field [0001] The invention belongs to the technical field of engine maintenance, and in particular relates to an engine valve guide wear amount measuring device, which is used for detecting the sloshing amount of an engine valve in the valve guide, so as to know the wear degree of the engine valve guide. Background technique [0002] As known in the industry, the valve guide not only ensures the linear reciprocating motion of the valve, so that the valve and the valve seat can fit correctly, but also plays a role of heat conduction between the valve stem and the cylinder head. There is generally a suitable gap (depending on the engine model) between the valve stem and the valve guide, so that the valve stem can move freely in the guide. When the valve stem moves in the guide tube, it is lubricated only by the oil splashed from the valve mechanism, which is easy to wear. The typical wear situation of the valve guide tube is that the upper and lower ends wear the mos...

AI Technical Summary

Problems solved by technology

The patent scheme uses stop and plug gauges to determine whether the engine valve guide hole is qualified; it is suitable for engine manufacturers with a single specification and model; it cannot be applied to the detection of worn out valve guide holes in the shape of oblate bell mouth

Therefore, this scheme exists the shortcoming that can not be used for such as the auto repair department of wide range, large amount, many models.
