Description

Technical Field

[0001] The invention relates to a supporting wheel type composite barrel section inner profile detection device and a use method thereof. Background Art

[0002] Composite barrel section refers to a cylindrical structural part made of composite materials. It has the advantages of light weight, high strength, and designable performance. It also has the characteristics of heat insulation, heat conduction, shock absorption, high (low) temperature resistance, corrosion resistance, wave transmission, and wave absorption. Therefore, it is an important structural material in the fields of aerospace, transportation, energy and chemical industry. However, due to the heterogeneity and anisotropy of composite materials, improper control of molding process parameters or insufficient curing during the preparation of barrel sections will lead to surface defects; and after the barrel sections are formed, complex cutting and surface processing procedures are required, which also creates conditions for the formation of surface morphology defects of the parts. The surface defects of composite barrel sections will not only reduce the structural strength of the parts, affect durability, and shorten the service life, but may also lead to serious safety risks. Especially in the application of key components such as aerospace, the defects of the surface of the parts may affect the overall reliability and safety of the structure. Therefore, accurate detection of surface defects in composite manufacturing is crucial to ensure the service performance of components.

[0003] The detection of the inner profile contour of composite barrel sections is an important part of the surface detection of composite barrel sections. It refers to the measurement and evaluation of the geometric shape and dimensional accuracy of the inner surface of the barrel section to ensure that it meets the design and functional requirements. Contour describes the degree of deviation of the actual contour of the composite barrel section from the ideal contour. It includes a comprehensive assessment of errors such as shape, direction, and position. The existing barrel section inner wall profile detection is done manually, that is, the operator climbs into the barrel section and uses a laser tracker to measure. This detection method is not only inefficient, but also difficult to implement due to the large size of the human body when detecting barrel sections with smaller apertures due to insufficient internal space for movement. In addition, the human body can easily block the light of the laser tracker, resulting in inaccurate detection and the risk of damaging the barrel section product.

[0036] In this embodiment, the rolling assembly 13 includes an adjusting sleeve 131 and a supporting roller 132, which are mounted on the connecting arm 123 by means of a set screw 4; the supporting roller 132 is arranged at one end of the adjusting sleeve 131, and the other end of the adjusting sleeve 131 is provided with a cavity whose shape and aperture match the outer contour of the connecting arm 123, and at least two positioning and mounting holes are arranged on the side wall of the adjusting sleeve 131, and the connecting arm 123 is inserted into the cavity of the adjusting sleeve 131, and the rolling assembly 13 is adjusted and fixed to a suitable position by means of the set screw 4, so that the supporting roller 132 can be supported on the inner wall of the barrel section and roll smoothly.

[0040] Example 2

[0041] This embodiment uses the support wheel type composite barrel section inner profile detection device described in Example 1 to detect the inner profile of a barrel section structure. Figure 6 As shown in the figure, the length of the barrel section structure is 7m, the diameter is 0.7m, and the theoretical diameter of the inner cavity is 0.538m. Since the diameter of the structure is small, manual inspection is difficult to implement and it is also very easy to damage the surface structure of the barrel section. Therefore, the inspection device of the present invention is used for inspection. The specific inspection process includes the following steps:

[0042] 1) Place the support mechanism 1 of the detection device into the composite tube section 3, as shown in FIG. Figure 7 As shown, a detection pull rope is tied to the pulling ring 5 of the bracket mechanism 1;

[0043] 2) Adjust the connection length between the connecting arm 123 and the adjusting sleeve 131 by means of the set screw 4, adjust the supporting rollers 132 to a suitable position so that they can be supported on the inner wall of the barrel section and roll smoothly, and then fix them;

[0044] 3) The connection length between the supporting circular tube 23 of the detection mechanism 2 and the plug-in sleeve 21 is adjusted by the positioning pin, so that the position of the detection target ball 24 on the inner surface of the composite tube section 3 slightly exceeds the theoretical position by 0.1 mm.

[0045] 4) Start the test, record the value measured by the test target ball 24, and use the test rope to pull the test device to move inside the composite barrel section 3 to fully test the inner surface profile of the composite barrel section 3. Part of the test data is shown in Table 1.

[0046]

[0047]

[0048] In the table, the rear end inner surface 10mm means that the measuring point is 10mm away from the end face; the measurement item is the inspection item required by the product engineering, the roundness is to evaluate the degree to which the product is close to the theoretical circle in the measured cross section, and the value is the difference between the maximum diameter and the minimum diameter of the measured cross section; the nominal value is the theoretical value, the tolerance is the allowable variation of the value of the measurement item, and the deviation is the value of the measurement item exceeding the theoretical allowable variation. Defects exist.

[0049] In this test, 18 test points were selected for measurement at a certain distance from the inner wall of the cylinder to the front and rear ends. The results of the measurement and analysis of 15 cross sections showed that the roundness of the inner wall of the cylinder met the engineering requirements; 7 of the diameter measurement items of the 15 cross sections were out of tolerance, which exceeded the engineering requirements and had defects. The out-of-tolerance values ​​were all negative, that is, the cylinder had defects of small diameter and thin wall in some areas.

[0050] It can be seen that the supporting wheel type composite barrel section inner profile detection device of the present invention can perfectly replace manual entry into the barrel section for detection, which is not only convenient for detection, but also more convenient and quicker than the existing detection method; and there is no need for manual entry into the barrel section, eliminating the possibility of personnel damaging the product during detection inside the barrel section, while reducing the number of personnel required for detection and reducing labor costs. At the same time, the detection mechanism is carried inside the barrel section by the detection frame mechanism, which has a simple structure and a small size, will not block the light of the laser tracker, and has accurate detection, and can be applied to the detection of the inner profile of composite barrel sections with different apertures, and is convenient to use, easy to control, and has good practical value.

[0051] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations within the meaning and scope of the elements of the claims be included in the invention.
