DETAILED DESCRIPTION

[0017] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0018] Please refer to Figures 1-16 The present application provides a welding detection platform based on visual amplification structure of digital twinning, which comprises a box 1, a support plate 15 and a support sliding plate 4, the support plate 15 is fixedly connected to the inner wall bottom surface of the box 1, the support sliding plate 4 is slidingly arranged on the periphery of the support plate 15, and the top surface of the support sliding plate 4 is rotatably provided with a placing rotating plate 43 for placing a product to be measured; A first bevel gear 6 is rotatably arranged on one side of the periphery of the support sliding plate 4, and a second bevel gear 7 is arranged on the other side of the periphery of the support sliding plate 4 and moves towards the placing rotating plate 43 along with the sliding of the support sliding plate 4, the second bevel gear 7 and the first bevel gear 6 are connected to form a ring bevel gear 67; An adjusting mechanism is arranged on the top surface of the inner wall of the box 1 and moves along the circumference of the ring bevel gear 67, a power mechanism is arranged on the adjusting mechanism and drives the ring bevel gear 67 to rotate, and a detection mechanism is arranged at the shaft center of the power mechanism; A linkage mechanism is arranged between the second bevel gear 7 and the placing rotating plate 43 and drives the placing rotating plate 43 to rotate along with the ring bevel gear 67.

[0019] In this case, as Figure 1It can be seen that two discharge openings 11 are formed on the top surface of the box 1, which are used to place the products to be tested on the placing turn plate 43 through the discharge openings 11, and then the products to be tested are moved to the first bevel gear 6 by the sliding of the supporting slide plate 4. In the process of sliding of the supporting slide plate 4, the second bevel gear 7 can move synchronously, and the second bevel gear 7 approaches the supporting slide plate 4. When the products to be tested are moved to the specified position, the second bevel gear 7 and the first bevel gear 6 are mutually connected to form an annular bevel gear 67, and the products to be tested are located in the annular bevel gear 67 at this time, so as to detect the products to be tested by the detection mechanism. The position of the power mechanism can be changed by adjusting the position of the adjusting mechanism, and then the distance between the power mechanism and the products to be tested is changed. The detection mechanism is arranged at the axis of the power mechanism, and the products to be tested can be effectively detected by the detection mechanism.

[0020] Among them, a display screen for displaying the state of the detected products to be tested is arranged on the side of the box 1, which can display images on the display screen in real time for observation.

[0021] Supplementary explanation: as shown in Figure 4 , Figure 14 and Figure 16 , the first bevel gear 6 and the second bevel gear 7 are both semi-annular structures, and after being connected, they form a bevel gear with annular structure. The annular bevel gear 67 is sleeved on the periphery of the placing turn plate 43 after being formed. The top surface of the annular bevel gear 67 is lower than the top surface of the placing turn plate 43, which can avoid the products to be tested from touching the annular bevel gear 67 during movement. Figure 2 As can be seen in the figure, the first bevel gear 6 is located on one side of the placing turn plate 43, and the second bevel gear 7 is located on the other side of the placing turn plate 43. The distance between the second bevel gear 7 and the placing turn plate 43 is less than the distance between the first bevel gear 6 and the placing turn plate 43. When the power mechanism rotates along the annular bevel gear 67, the distance between the power mechanism and the placing turn plate 43 can be changed. When close-range detection is needed, the position of the power mechanism can be changed by driving the adjusting mechanism, so as to change the position of the detection mechanism and make the detection mechanism close to the products to be tested for detection, avoiding blurring during imaging and improving clarity. At the same time, it can realize the state of point detection, that is, when the detection mechanism approaches the products to be tested, it can detect the specified part of the products to be tested, and the detection image can be displayed more clearly on the display screen, avoiding manual magnification of the display screen during detection.
