Abstract

The invention discloses a machining process of a durable low-carbon steel spline plug gauge, and aims to solve the technical problems of high material specificity, high machining difficulty and high machining cost of an existing spline plug gauge. The method generally includes the following steps of firstly, roughly and finely turning an excircle of a low-carbon alloy steel bar, grinding a plug gauge working position of the low-carbon alloy steel bar, hobbing the low-carbon alloy steel bar, roughly grinding spline teeth of the low-carbon alloy steel bar, carburizing, quenching and tempering the low-carbon alloy steel bar, grinding a center hole and the excircle of the plug gauge, and at last, finely grinding the tooth profile according to the size of a finished product to obtain the finished spline plug gauge. According to the process, the raw materials for machining of the spline plug gauge can be greatly expanded, the machining difficulty is lowered, the manufacturing period is shortened, and the machining cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of mechanical parts production, and in particular relates to a processing technology of a durable low-carbon steel spline plug gauge. Background technique [0002] Spline plug gauge is a commonly used inspection tool for quickly detecting the action size of involute splines. Existing professional tool factories generally use alloy tool steel materials with high carbon content to make spline plug gauges, such as Alloy tool steel CrWMn, etc. Alloy tool steel can obtain higher surface hardness (generally 60-64HRC) after quenching, so that it has good wear resistance and thus ensures the life of the inspection tool. However, in the current production field of spline plug gauges, because alloy tool steel is only used as special-purpose steel, the reserve is small and the processing cost is high. Quenching), and general non-professional tool production enterprises basically do not have such equipment suitable for tool stee...
