Internal thread automatic detection device

Abstract

The invention discloses an internal thread automatic detection device, and belongs to the technical field of mechanical automation. The internal thread automatic detection device solves the problem that in the prior art, an internal thread detection device is low in accuracy, poor in universality and low in detection speed. The internal thread automatic detection device comprises a machine cabinet, a rotating device and a detection device, wherein the rotating device is arranged in the middle of the machine cabinet, and the detection device is distributed on the periphery of the rotating device in an annular mode. A calibration device is further arranged on the surface of the machine cabinet. The detection device comprises a first detection mechanism, a second detection mechanism and a material taking mechanism, wherein the first detection mechanism, the second detection mechanism and the material taking mechanism are arranged along an index plate in the counterclockwise direction. According to the internal thread automatic detection device, the static and dynamic relative displacement changes between a detected part and a probe are accurately detected by the use of an eddy currenttechnology, and therefore internal thread detection cannot be affected by the inner surfaces of threaded products, the measuring accuracy is guaranteed, and the application range is broadened. Multidimensional non-contact detection is conducted on various types of products by use of the second detection mechanism, and therefore the accuracy of internal thread detection is improved. The first detection mechanism and the second detection mechanism are suitable for detecting different detected parts, and therefore the universality of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical automation, and in particular relates to an automatic detection device for internal threads. Background technique [0002] Threaded parts have the advantages of easy assembly and disassembly, making them widely used in machinery manufacturing, aerospace, nuclear power, chemical industry, military industry and other fields. In addition to the mechanical properties of threaded parts related to materials and processing technology, the processing quality of geometric parameters It is also an important factor affecting its performance. Internal threads are usually inspected by means of go-no-go gauges, endoscopes, standard gages, and visual sensors. However, the tolerance of plug gauge inspection is relatively large, and other inspection methods are suitable for single inspection. They have poor versatility and are easily affected by the internal processing quality of parts. , leading to problems s...
