Salt bath nitriding ring gauge

Abstract

The invention provides a salt bath nitriding ring gauge which is mainly composed of a ring gauge base (1), an oblique cut (2), a measurement plane (3), a step (4) and a salt bath nitriding layer (9). The salt bath nitriding ring gauge is characterized in that the surface of the ring gauge base (1) is provided with the nitriding layer (9) formed through the mode of salt bath nitriding. The thickness of all the salt bath nitriding layer (9) around the ring gauge base (1) is greater than 0.05mm. With application of the salt bath nitriding ring gauge in the further, multiple disadvantages that the conventional ring gauge is short in the service life and frequently replaced and unnecessary tool cost of the enterprise is increased can be overcome.

Description

Technical field: [0001] The invention belongs to a kind of piston ring detection tool, in particular to a salt bath nitriding ring gauge. Background technique: [0002] For the piston ring installed in the cylinder liner of an automobile engine, the size of the opening or whether there is light leakage on the outer surface is one of the main conditions to ensure the sealing of the cylinder. The size of the opening before the installation of the piston ring and the light leakage detection on the outer surface of the piston ring are essential In one process, the original ring gauge has a short service life, which brings many disadvantages such as high cost of tooling production, frequent replacement, and inaccurate measurement to the enterprise. Therefore, I specially invented this salt bath nitriding ring gauge. Invention content: [0003] The purpose of the present invention is to provide a salt bath nitriding ring gauge, which has a small size, can not only meet the needs...
