Description

Technical Field

[0001] This utility model relates to the field of tire analysis technology, and more specifically to a fixing device for tire section study. Background Technology

[0002] As is well known, tire cross-section scanning involves laterally slicing the tire and placing the extracted cross-section into a scanning device to extract the structural features inside the actual tire cross-section. Tires have high elasticity, and the outer contour of the extracted tire cross-section, due to the lack of constraint, differs significantly from that of the complete tire. Therefore, it is necessary to artificially constrain the tire cross-section to restore its structural components to their original positions before tire structure analysis can be performed. Research in this field contributes to improving the ability to predict material and structural design schemes during the tire design phase and enhancing the analytical capabilities of mechanical simulation work.

[0003] Currently, patents related to tire section fixing devices generally lack universality and practicality. On the one hand, it is difficult to accurately fix the outer contour of the tire section onto the specified actual contour; on the other hand, it lacks universality and often cannot be flexibly matched to various tire specifications. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this utility model provides a fixing device for tire cross-section research. Its purpose is to achieve the following: during tire cross-section scanning, the outer contour of the tire cross-section can be effectively made to match the target contour, which is generally the actual outer contour of the tire when it is loaded; the device structure can be easily and flexibly adjusted according to different tire cross-section specifications and used directly without the need for further processing of spare parts; and the device can reduce the error caused by operation during scanning and obtain accurate and clear tire cross-section images on the tire cross-section scanning instrument.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a fixing device for tire cross-section research, which is equipped with a fixing plate. The fixing plate is characterized by having a limiting groove machined on it, and two adjusting limiters are installed in the limiting groove. The adjusting limiter includes a limiting post and a limiting screw. The limiting screw is located at the bottom of the fixing plate. The limiting screw passes through the limiting groove to fix the limiting post to the side of the fixing plate. There are concave holes machined at the four corners of the side of the fixing plate. A support post is inserted into each concave hole. A positioning screw is installed at the upper end of each support post. Two height adjustment nuts are screwed on the positioning screw. Transparent cellophane printed with the outer contour of the tire is fitted onto the height adjustment nuts through the round holes at the four corners.

[0006] The beneficial effects of this utility model are that it can effectively make the outer contour of the tire cross section completely consistent with the target contour during tire cross section scanning, and can conveniently adjust the device structure according to different tire cross sections and use it directly, reducing the error caused by operation during scanning and obtaining accurate and clear tire cross section images.

[0013] In the figure, this utility model includes a fixing plate 1 with a hole in the middle. Limiting grooves 10 are distributed on the fixing plate 1, and two adjusting limiters are installed in each limiting groove 10. The two adjusting limiters in each limiting groove 10 provide partial fixation from the inside and outside of the tire section 9. Simultaneous fixation of multiple adjusting limiters can completely fix the tire section 9. Each adjusting limiter includes a limiting post 4, a limiting screw 5, and a washer 6. The limiting screw 5 and washer 6 are located at the bottom of the fixing plate 1. The limiting screw 5 passes through the washer 6 and the limiting groove 10 to fix the limiting post 4 to the upper side of the fixing plate 1. Recessed holes 11 are machined at the four corners of the upper side of the fixing plate 1. A support post 2 is inserted into each recessed hole 11. A replaceable positioning screw 7 is installed at the upper end of each support post 2. Two height-adjusting nuts 3 are screwed onto the positioning screw 7. Transparent cellophane 8, printed with the outer contour of the tire, is fitted onto the height-adjusting nuts 3 through the round holes at its four corners.

[0014] The method of using this utility model is as follows:

[0015] S1. Print the outline of the target tire onto transparent cellophane 8 using a printer, and fix it to the support pillars 2 located at the four corners through the round holes at the four corners of the transparent cellophane 8 using positioning screws 7 and adjusting nuts 3, and keep the transparent cellophane 8 horizontal by adjusting the adjusting nuts 3.

[0016] S2. Fix the adjusting limiter to the outside of the target contour using the limiting screw 5 and the washer 6, so that when the transparent cellophane 8 is viewed from directly above, the adjusting limiter is in close contact with the target contour line.

[0017] S3. Remove the transparent glass paper 8, place the tire section 9 on the fixing plate 1, tighten the adjusting limiter on the inside of the tire section 9 to complete the fixing of the tire section 9, and further check the matching of the tire section 9 with the target contour through the transparent glass paper 8.

[0018] S4. During scanning, the necessary annotations can be printed on paper and placed in the hole in the middle of the fixing plate 1 as markings. The actual size of the image can be determined by the square on the fixing plate 1. The square refers to... Figure 4 The 10 by 10 millimeter squares on the surface, i.e. the square relief on the surface, are used for size calibration.
