Abstract

The invention discloses a method for detecting the orifice of a conical bore, and the method comprises the steps: the size analysis of a to-be-detected part, the machining of a measuring tool, the setting of an upper deviation line, the setting of a lower deviation line, and the measurement. According to the invention, a conical body with the same taper as a to-be-detected conical bore is provided with the upper and lower deviation lines at an interval, and the conical body is put in the conical bore of the to-be-detected part. When an end face of the detected part is located within the two scribed lines on the conical body, the detected part is determined to be qualified; or else, the detected part is detected to be unqualified. Compared with a conventional measurement method employing a vernier caliper, the method is convenient for operation, is low in cost, is high in measurement precision, can greatly reduce the manpower and time consumption, and also can meet the high-precision requirements of measurement.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a measuring device for mechanical processing, and in particular to a method for detecting the opening of a conical hole. Background technique [0002] In the field of mechanical processing technology, it is often necessary to process a tapered hole on a part. The size of the tapered hole after processing is required to be relatively high, especially for some high-precision parts. In the process of traditional tapered hole processing, the main method is to rely on vernier calipers. Measuring the orifice size of the conical hole, since the conical orifice to be processed is located on a line, measuring the orifice of the conical hole with a vernier caliper cannot accurately measure the orifice size, which is not only slow and inefficient, but also requires a lot of manpower and It takes time and the cost is high. In addition, the traditional measurement method has poo...
