[0025] Example

[0026] like Figure 1 、 Figure 2 and Figure 4 As shown, an embodiment of the present invention proposes a curved surface non-destructive testing frame, including a base plate 1, and also includes: a support frame 2, fixed on the base plate 1; a turntable 3, rotatably connected to the support frame 2, and one side of the turntable 3 is fixedly connected to an array-distributed clamping mechanism 4 for positioning and clamping the pipe fitting, the clamping mechanism 4 includes a round rod 401 fixedly connected to one side of the turntable 3, and a horizontal plate 402 fixed to the end of the round rod 401, a track groove 407 is opened on the horizontal plate 402 along its length direction, and a slider 4011 is slidably connected to the track groove 407 of the horizontal plate 402, and the slider 4011 and the horizontal plate 402 are both rotatably connected to a shaft rod 404, one of the shaft rods 404 is fixed with a first positioning cylinder 405, and the other shaft rod 404 is fixed with a second positioning cylinder 406, the first positioning cylinder 405 and the second positioning cylinder 406 are in contact with the inner wall of the pipe fitting, thereby realizing the positioning and clamping of the pipe fitting.

[0027] It should be noted that the bottom plate 1 is the bottom support part of the device, and the support frame 2 is used to support and install the turntable 3. By setting an array of distributed clamping mechanisms 4 on one side of the turntable 3, the clamping mechanism 4 is used to clamp the pipe fittings, and then the non-destructive testing of the curved surface of the pipe fittings is carried out in batches. The clamping mechanism 4 is mainly composed of a horizontal plate 402, a shaft 404, a first positioning cylinder 405, a second positioning cylinder 406, a slider 4011, etc., wherein the slider 4011 can slide at the track groove 407 of the horizontal plate 402 , to realize the moving function of the second positioning cylinder 406. When in use, the pipe fitting is placed on the outside of the first positioning cylinder 405 and the second positioning cylinder 406. When the slider 4011 moves, it drives the second positioning cylinder 406 to move, so that the first positioning cylinder 405 and the second positioning cylinder 406 are in contact with the inner wall of the pipe fitting, forming a supporting effect on the inner side of the pipe fitting, and then positioning and clamping the pipe fitting. At the same time, the first positioning cylinder 405 can rotate by itself, and when rotating, it can make the pipe fitting rotate, and then realize the axial detection of the curved surface of the pipe fitting.

[0029] It should be noted that the first motor 403 can drive the shaft 404 and the first positioning cylinder 405 to rotate. After the first positioning cylinder 405 and the second positioning cylinder 406 support the inner wall of the pipe, the first positioning cylinder 405 rotates to realize the self-rotation of the pipe, and then the axial detection of the curved surface of the pipe is performed.

When the first screw rod 409 rotates, the slider 4011 can move along the track groove 407, adjust the distance between the first positioning cylinder 405 and the second positioning cylinder 406, and then achieve clamping of the inner wall of the pipe.

[0033] It should be noted that the fourth motor 6 can drive the turntable 3 to rotate, realize the revolution of the clamping mechanism 4, and then drive the corresponding pipe to rotate.

[0034] like Figure 1 and Figure 3 As shown, in some embodiments, a detection mechanism 5 is installed on the base plate 1, and the detection mechanism 5 includes a protective frame 501 fixedly connected to the base plate 1, and a second screw rod 502 rotatably connected to the inner side of the protective frame 501, a sliding plate 505 is threadedly connected to the second screw rod 502, and a support arm 506 is fixedly connected to the sliding plate 505, and a detection probe 508 is installed on the mounting seat 507 set on the top of the support arm 506, and non-destructive testing of the curved surface of the outer surface of the pipe fitting is achieved through the detection probe 508.

[0035] It should be noted that when the second screw 502 rotates, the sliding plate 505, the support arm 506, the mounting seat 507 and the detection probe 508 can move, and the detection probe 508 contacts the outer surface of the pipe fitting, thereby realizing non-destructive testing of the curved surface of the outer surface of the pipe fitting. Under the action of the first positioning cylinder 405, the pipe fitting can automatically rotate, and the detection probe 508 moves laterally during the process to realize axial detection of the pipe fitting, and the detection effect is perfect. Among them, the working principle and usage of the detection probe 508 are known existing technologies and will not be elaborated on.

[0036] like Figure 3 As shown, in some embodiments, a limiting rod 503 is fixedly connected to the inner side of the protective frame 501, and a limiting hole adapted to the limiting rod 503 is opened at the sliding plate 505 corresponding to the limiting rod 503, and a third motor 504 for driving the second screw rod 502 to rotate is installed on one side of the protective frame 501.

[0037] It should be noted that the setting of the limit rod 503 can realize the movement limit of the sliding plate 505, and the third motor 504 can drive the second screw rod 502 to rotate, thereby moving the sliding plate 505, the support arm 506 and the detection probe 508 to realize the detection of the curved surface of the pipe fitting.
