Air valve spring detection tool

Abstract

The invention provides an air valve spring detection tool which comprises at least one detection unit. The detection unit comprises an external diameter detection cylinder and an internal diameter detection cylinder, wherein the internal diameter detection cylinder is in the external diameter detection cylinder, the middle and upper part of them are separated by spring detection groove, and the lower part of them are connected as one body. The internal diameter of the external diameter detection cylinder is a limit external diameter of a standard air valve spring, the external diameter of the internal diameter detection cylinder is a limit internal diameter of the standard air valve spring, and the depth of the spring detection groove is greater than or equal to the height of the standard air valve spring. According to the air valve spring detection tool in the invention, the external diameter and internal diameter of the spring are respectively detected through the external diameter detection cylinder and the internal diameter detection cylinder, and the detection groove is used for detecting the height and verticality of the spring. Through detecting whether the spring can enter the groove normally or not and whether the height of the spring can reach a corresponding position or not, whether the related dimensions of the spring satisfy the requirement or not is determined. The air valve spring detection tool has a simple structure and is convenient in detection. In addition, the detection tools can be integrated as a detection board to detect a plurality of springs at a time and raise detection efficiency.

Description

technical field [0001] The invention relates to a detection tool for engine parts, in particular to a detection tool for valve springs on the engine. Background technique [0002] The valve springs of traditional engines have size requirements such as verticality, height, inner diameter, outer diameter, etc. These dimensions need to be tested with different tools, and because the valve spring is helical, it is difficult to detect the appropriate parts, resulting in difficult detection and inaccurate detection data. Contents of the invention [0003] The invention is a valve spring detection tool designed for the problem of difficulty in valve spring detection. The tool can simultaneously detect whether the inner diameter, outer diameter, verticality, height, etc. of the valve spring meet the requirements. [0004] Technical scheme of the present invention is as follows: [0005] A detection tool for a valve spring, which includes at least one detection unit, the detectio...
