Embodiment 1

[0021] figure 1 As shown, the automatic coding wire take-up device provided in this embodiment includes a box body 1, and a rotatable wire reel 2 and an elastic member 3 providing a restoring force for the reel 2 are arranged in the case body 1, so that A length encoder 4 is also arranged in the box body 1, and the length encoder 4 has a code wheel 5, and an auxiliary wheel 6 is also arranged near the code wheel 5, and an outlet hole 7 is also provided on the box body 1, so that A coding line (not shown in the figure) is wound on the winding wheel 2 , and the end of the coding line passes through the position between the coding wheel 6 and the auxiliary wheel 7 and is drawn out from the wire outlet hole 7 .

[0022] In this structure, the entire coding line is wound on the winding wheel, and the function of the automatic coding line take-up is: when the coding line is stretched by external force, the coding line passes through the length encoder in between to obtain the stretc...

Embodiment 2

[0024] Based on the automatic coding wire take-up described in the first embodiment above, this embodiment also provides a stress nephogram imaging system, such as figure 2 As shown, it includes two automatic coding wire take-ups 101 and 102, and the two automatic coding wire take-ups are set at a certain distance apart. The system also includes a detection host 103, and the coding wire ends of the two automatic coding wire On the detection host 103, the detection host is used to detect and store the stress data of the parts to be inspected, and at the same time receive the length data uploaded by the two automatic encoding wire take-ups, combined with the distance between the two automatic encoding wire take-ups, accurate Calculate and display the precise position information of the testing host, and obtain the two-dimensional stress nephogram of the parts to be tested.

[0025] The main purpose of the invention is to obtain the stress nephogram of the parts to be inspected....

Embodiment 3

[0033] The automatic encoding wire take-up device provided in this embodiment is based on the first embodiment, and a circumferential encoder is installed on the outlet hole, and the end of the coding line is drawn out from the outlet hole, and bypasses the circumferential encoder. In the detection, the code line drives the length encoder and the circumference encoder at the same time. The information fed back to the detection host by the automatic encoding wire take-up includes the length information and angle information of the encoding line. Therefore, through polar coordinate positioning, the position of the detection host can be accurately known.

Abstract

The invention relates to the technical field of nondestructive detecting, and provides an automatic coding wire take-up device and a stress nephogram imaging system. The automatic coding wire take-updevice comprises a box body, the box body is internally provided with a rotatable wire winding wheel and an elastic piece for providing restoring force for the wire winding wheel, and a length coder is further arranged in the box body; the length coder is provided with a coding wheel, and an auxiliary wheel is further arranged nearby the coding wheel; and a wire outlet hole is further formed in the box body, a coding wire is wound around the wire winding wheel, and the tail end of the coding wire penetrates through the position between the coding wheel and the auxiliary wheel and then is led out form the wire outlet hole. In the preferred scheme, a circumference coder is further mounted in the wire outlet hole, and the tail end of the coding wire is led out from the wire outlet hole and then bypasses the circumference coder. According to the automatic coding wire take-up device and the stress nephogram imaging system, the original stress magnetic signal detection density is increased,on the basis of obtaining stress magnetic signal imaging, various eigenvalue calculation in the plane can be achieved, and original point detection and line detection are expanded to present surface detection and space detection.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing, and in particular relates to an automatic encoding wire take-up device and a stress nephogram imaging system. Background technique [0002] Conventional non-destructive testing techniques such as ultrasonic testing, radiographic testing, magnetic particle testing, magnetic flux leakage testing, eddy current and penetration testing, etc., are aimed at the detection of macroscopic volume defects of materials, and cannot detect defects caused by manufacturing, installation, use and other factors of the workpiece. Stress damage and deformation that form volume defects are detected. [0003] Magnetic memory stress detection technology is a detection method for metal fatigue damage. It was originally proposed by Russian scholar Dubov, and pointed out that the stress concentration area is characterized by the maximum value of the tangential component of the magnetic field and the zero-cr...
