Problems solved by technology

[0005] The purpose of the present invention is to provide a rivet tightness detection device and its use method. The present invention obtains the rivet deviation factor through the analysis of the rivet deviation analysis unit, and obtains the rivet fluctuation factor through the analysis and calculation of the rivet fluctuation analysis unit. Based on the rivet fluctuation factor and The rivet fastening coefficient obtained by the rivet deviation factor can not only detect rivets with different degrees of looseness, and has a wide range of applications, but also can obtain the fastening degree of rivets through detection and analysis, so as to realize the intuitive understanding of the fastening degree of rivets, and the detection results are accurate High performance, good use effect, solves the problem that currently only the rivets that are very loose can be detected, the scope of application is narrow, and the degree of fastening of the rivets cannot be intuitively understood, it is difficult to detect the degree of fastening of the rivets, and the detection results are inaccurate , the problem of poor use effect

Embodiment 1

[0058] as Figure 1-10 As shown, a rivet tightness detection apparatus proposed in the present invention, comprising a processor, and the processor and the shooting detection unit, rivet deviation analysis unit, tapping detection unit, rivet fluctuation analysis unit, display module and control terminal communication connection; Display unit displays inspection data, analysis data and tightening degree information to enable the operator to intuitively connect the inspection process and analysis results; The control terminal is used to issue control commands to control shooting and tapping, so that the inspector can control it; Shooting detection unit for shooting rivets and sending captured images to the processor, which transmits the captured images to the rivet deviation analysis unit; The image taken by the capture detection unit includes an image in four directions, namely the image of the X side, the image of the -X side, the image of the Y side and the image of the -Y side, a...

Embodiment 2

[0064] The present embodiment differs from Example 1 in that the present invention proposes a method of using a rivet fastness detection device, comprising the following steps:

[0065] Step 1, the inspector manually touches the rivet, and applies a force to the rivet, if the finger does not feel a significant displacement, then continue to the next step, if the finger feels a significant displacement, then there is no need for the next step;

[0066] Step 2: The inspector controls the shooting through the control terminal, and the shooting detection unit shoots the X side, -X side, Y side and -Y side of the rivet, and sends the captured image to the processor, and the processor transmits the captured image to the rivet deviation analysis unit;

[0067] Step 3: The rivet deviation analysis unit processes the obtained rivet image and analyzes the gap value between the rivet cap and the connected member, and the rivet deviation analysis unit calculates the rivet deviation factor WQj...

Abstract

The invention belongs to the technical field of rivet tightness detection, is used for solving the problems that at present, only rivets which are loosened very obviously can be detected, the application range is narrow, the tightness of the rivets is difficult to obtain through detection and analysis, and the detection result is inaccurate, and particularly relates to a rivet tightness detection device and a use method thereof. The processor is in communication connection with the shooting detection unit, the rivet deviation analysis unit, the knocking detection unit, the rivet fluctuation analysis unit, the display module and the control terminal; the rivet deviation factor is obtained through analysis of the rivet deviation analysis unit, the rivet fluctuation factor is obtained through analysis of the rivet fluctuation analysis unit, the rivet fastening coefficient is obtained based on the rivet fluctuation factor and the rivet deviation factor, rivets with different looseness degrees can be detected, the application range is wide, and the detection precision is high. And the fastening degree of the rivet can be obtained through detection and analysis, so that the fastening degree of the rivet can be intuitively known, and the accuracy of the detection result is high.

Description

Technical field [0001] The present invention relates to the field of rivet tightness detection technology, specifically a rivet tightness detection device and a method of use thereof. Background [0002] Rivets are nail-shaped objects, one end of which has a cap, in the riveting, which uses its own deformation or interference to connect the riveted parts, in the use of rivets, if the use of rivets for too long or when the riveting was not tightened, will lead to rivet loosening, when the rivets appear loose and undiscovered, it is easy to cause the connector to detach, which is easy to cause damage to the connector, so it is generally necessary to regularly detect the fastness of the rivets on the connector; [0003] At present, when the fastness of the rivets on the connected parts is detected, it is generally observed through the human eye whether the rivets are tilted, or the size of the gap between the rivet cap and the connected parts is observed, and the rivets are manually...
