[0032] Reference Figure 2As shown, the horizontal moving device 3 includes a horizontal drive motor 31, a horizontal lead screw 32, and a horizontal moving bracket 33. Both the horizontal drive motor 31 and the horizontal lead screw 32 are mounted on the test bracket 2, and the output end of the horizontal drive motor 31 is connected to one end of the horizontal lead screw 32. The horizontal moving bracket 33 is fixedly connected to the low-end nut of the horizontal lead screw 32. The vertical moving device 4 is mounted on the horizontal moving bracket 33.

[0035] In the above structure, the rotating connecting plate 52 includes a rectangular connecting plate 521 and two symmetrically arranged rotating plate bodies 522. The two symmetrically arranged rotating plate bodies 522 are respectively arranged on two opposite surfaces of the rectangular connecting plate 521. The rectangular connecting plate 521 and the two symmetrically arranged rotating plate bodies 522 are arranged in a U-shape. The cross-section of the rotating plate body 522 is semi-circular. The rotating plate body 522 is provided with several through holes 523 along the circumferential direction. The fixed bracket 51 is provided with through holes 512. The fixed pin 54 passes through the through holes 523 and through holes 512. The fixed bracket 51 is located between two symmetrically arranged rotating disk bodies 522. When the rotating disk body 522 rotates around the pin 53 to the desired position, the first through hole 523 and the second through hole 512 are aligned, and the fixing pin 54 is inserted into the first through hole 523 and the second through hole 512, thereby fixing the fixed bracket 51 and the rotating connecting disk 52.

[0037] Reference Figure 7As shown, the floating device 6 includes a housing 61, a power source 62, a pressure sensor 63, a floating plate 64, and a connecting rod 65. The housing 61 is connected to the angle adjustment device 5. The power source 62 is fixedly installed inside the housing 61, and its output end is connected to the floating plate 64 via the pressure sensor 63. The pressure sensor 63 is used to sense the pressure between the roller 7 and the curved surface of the part to be tested. One end of the connecting rod 65 extends into the housing 61 and connects to the floating plate 64, while the other end extends out of the housing 61 and connects to the roller 7. The power source 62 can be a hydraulic cylinder, an electric cylinder, or a pneumatic cylinder. A floating bracket 66 is provided inside the housing 61, and a linear guide rail 661 is provided on the floating bracket 66. A floating slider 67 is connected to the floating plate 64, and the floating slider 67 and the linear guide rail 661 are slidably connected. A displacement sensor 68 is provided on the floating bracket 66, and the displacement sensor 68 is used to sense the movement position of the floating plate 64.

[0038] The working principle of the above-mentioned floating device 6 is as follows:

[0039] First, the pushing function of the power source 62 causes the roller 7 to extend forward, so that the roller 7 can touch the sheet metal surface of the part to be tested. When the roller 7 suddenly turns from the flat area into the groove, the pressure sensor 63 will immediately detect it and transmit the detected information to the controller. After receiving the information, the controller will analyze it and synchronously feed back the information to the power source 62. The power source 62 will push the roller 7 to increase pressure (or decrease pressure) according to the computer's instructions, so that the pressure applied by the roller 7 to the sheet metal surface is consistent or similar, whether the roller 7 is in the flat area or the groove.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
