Problems solved by technology

At present, there are many technologies that can realize metal defect detection at home and abroad, such as eddy current flaw detection, magnetic particle flaw detection, ultrasonic flaw detection and radiographic flaw detection. Disadvantages of high radioactive hazard, many human factors, high cost and inconvenient operation
Domestic bevel gear full-tooth side defect detection mainly adopts manual detection method, which is time-consuming, laborious, poor in inspection consistency and difficult to meet the quality inspection needs of large-scale high-speed gear production, while the automatic, fast and stable bevel gear full-tooth direction detection method The detection method does not exist at home and abroad

Embodiment Construction

[0013] The present invention will be described in more detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the bevel gear full-tooth side defect multi-eye detection device includes a frame group 1 with a frame type bottom, and a gear fixing device 2 is placed on the top surface of the frame group 1, and the gear fixing device 2 is the same as the frame group 1. The rotation transmission structure of the set angle division system 3 is connected, and the top of the gear fixing device 2 has a protrusion 10 that can adapt to the bevel gear to be tested in the shaft sleeve. The inner top of the photographic acquisition unit 4 is provided with a top camera 11 whose lens faces the protrusion 10, and the inner top of the photographic acquisition unit 4 is also provided with a highlight lighting unit 5. In addition, the interior of the photographic acquisition unit 4 is provided with a uniform surrounding distribution There are seven side ca...

Abstract

The invention discloses a multicast detection device and method for full-depth tooth side face defects of a bevel gear. In the invention, a multi-camera synchronous acquiring and processing mode is adopted, and a multicast detection method for full-depth tooth side face defects of a bevel gear having the advantages of high speed, high accuracy, high recognition rate, low hardware cost and convenience for operating and maintaining is realized. The method further has the advantages of high automation degree and high security.

Description

technical field [0001] The invention belongs to the technical field of gear detection, in particular to a multi-eye detection device and a detection method for bevel gear full-tooth side defects. Background technique [0002] Bevel gears have a large number of teeth, different tooth surfaces, and various types of defects. For example, a planetary gear has 14 teeth and 28 tooth surfaces. The defects include bumps, cracks, insufficient filling, folds, scratches, depressions and protrusions. . How to realize the real-time on-line detection of different flank defects of bevel gear full teeth is the biggest difficulty in bevel gear full tooth flank inspection. At present, there are many technologies that can realize metal defect detection at home and abroad, such as eddy current flaw detection, magnetic particle flaw detection, ultrasonic flaw detection and radiographic flaw detection. It has the disadvantages of high radioactive hazard, many human factors, high cost and inconv...
