Description

Technical Field

[0002] Carbon fiber square tubes are made of thermosetting resin as the matrix and carbon fiber as the reinforcement material through a composite process. They have the characteristics of high specific strength, high specific modulus, fatigue resistance, corrosion resistance, and strong designability. Therefore, carbon fiber square tubes are usually used in fields that require lightweight and high-strength materials. Before using the carbon fiber square tube, it is necessary to ensure that it can meet the design requirements in actual applications and avoid the degradation of structural performance due to excessive bending. The curvature of the carbon fiber square tube needs to be tested. However, most of the existing carbon fiber square tubes use the human eye to detect the curvature, and the detection accuracy of the human eye detection is not high. At the same time, due to the long length of the carbon fiber square tube, the human eye detection requires the detection personnel to move frequently, which is time-consuming and makes the detection efficiency low.

Then, when the carbon fiber square tube is placed, it fits with the side of the clamping plate 3, and the clamping is driven by the guide assembly.

In the process of moving the carbon fiber square tube, the guide assembly drives the blowing assembly to work, and enables the blowing assembly to blow and clean dust and other impurities on the side of the carbon fiber square tube that needs to be inspected.

When the detection area inside the placement groove 10 is detected, the clamping of the carbon fiber square tube can be loosened and the carbon fiber square tube can be moved so that other areas can also enter the placement groove 10 for detection. The carbon fiber square tube can also be flipped over, so that the curvature of the four sides of the carbon fiber square tube can be detected as needed, and the lateral position of the laser detector 4 can be adjusted by the adjustment component, and the laser detector 4 can be adapted to the detection of carbon fiber square tubes of different widths, thereby making the device meet more usage requirements. The laser detector 4 in the device uses laser scanning to detect the surface of the square tube, obtains data on the surface of the tube body, and calculates the curvature of the tube body through software analysis of the external terminal.
