Abstract

The invention relates to the technical field of aperture detecting tools, and in particular to a go gauge and no-go gauge detection device, and an inner hole aperture detection method. The go gauge and no-go gauge detection device comprises: a main body, the main body is provided with a no-go gauge portion, a go gauge portion and a detecting portion; when the distance of the no-go gauge portion inserted into a shaft hole of an object to be detected is equal to one third of the depth of the shaft hole, a position difference value between the object to be detected and the detecting portion is used as a preset value; and when the distance of the no-go gauge portion inserted into the shaft hole of the object to be detected is greater than one third of the depth of the shaft hole, the detectingportion indicates that the object to be detected does not meet the design requirement via the fact that the position difference value between the object to be detected and the detecting portion is less than a preset value. Therefore, only by comparing the position difference value between the object to be detected and the detecting portion disclosed on the no-go gauge portion, a certain product is an unqualified product can be easily detected and indicated, that is, the tolerance zone distribution of the inner hole aperture can be accurately and quickly identified, thereby shortening the detection time and speeding up the detection efficiency.

Description

technical field [0001] The present application relates to the technical field of aperture detection tools, in particular to a pass-stop detection device and an inner aperture detection method. Background technique [0002] At present, the aperture of existing mechanical parts is often measured with a go-no-go gauge, and the detection of the open end is relatively simple, but for some mechanical parts such as the inner aperture of the refrigerator compressor motor rotor, the inner hole size has a certain aperture tolerance Requirements, for example, for the inner diameter of the refrigerator compressor motor rotor, it is necessary to have certain skills and experience in the end-stop detection. In the end-stop measurement, quite a lot of states are that the stop end of the plug gauge will be slightly inserted into the inner hole. The process standard in this industry has a certain acceptable range, that is, the stop end can be inserted into the hole one-third of the hole dept...
