[0035] like Figure 2 and Figure 4 as well as Figure 5As shown, the flipping device 5 includes an electric telescopic rod 55, which is installed on the side of the side plate 402 away from the bottom plate 401, and the output end of the electric telescopic rod 55 is fixedly connected to a pressing plate 56. By setting the electric telescopic rod 55, the pressing plate 56 can be controlled to move, so as to control the pressing plate 56 to flip the curved workpiece, which is convenient for detecting different surfaces of the curved workpiece.

[0037] Working principle: After the curved workpiece to be inspected is clamped by the curved workpiece inspection fixture, the curved workpiece to be inspected is moved close to the detector 3 by the conveyor belt 2 on the base 1, and then the detector 3 is used to inspect it. When the curved workpiece to be inspected needs to be clamped, the curved workpiece to be inspected is first moved close to the bottom plate 401, and then the motor 407 is started to drive the control screw 406 to rotate. The rotation of the control screw 406 drives the moving plate 404 to move close to the side plate 402, so that the moving plate 404 and the fixed plate 403 clamp the curved workpiece. During the movement of the moving plate 404, the control screw 406 rotates on the surface of the fixed plate 403, and the moving plate 404 slides on the surface of the slide bar 408. By setting the limit Plate 409 can ensure the connection between the slide bar 408 and the movable plate 404. By setting the rubber plate 405, the clamping effect of the curved workpiece can be increased. By setting the mounting frame 410, the motor 407 can be connected to the side plate 402. By setting the clamping device 4, it is convenient to clamp or release the curved workpiece to be inspected. At the same time, it can be ensured as much as possible that after the curved workpiece is clamped, the curved workpiece will not be deflected due to the moving curved workpiece inspection fixture.
[0038] After the curved workpiece to be inspected is fixed on the bottom plate 401, the moving slide plate 51 drives the slider 57 to slide on the surface of the slide groove on the side plate 402, thereby adjusting the position of the slide plate 51 so that the pressure plate 56 is aligned with the edge position of the curved workpiece, and then the limiting screw 52 is rotated to make the abutment plate 53 move closer to the side plate 402 to fix the position of the slide plate 51. When inspecting the curved workpiece, when it is necessary to inspect different surfaces of the curved workpiece, the motor 407 is started to move the moving plate 404 away from the fixed plate 403, so that the moving plate 404 and the fixed plate 403 can limit the position of the curved workpiece without affecting the rotation of the curved workpiece, and then the motor 407 is started to move the moving plate 404 away from the fixed plate 403. The electric telescopic rod 55 drives the pressure plate 56 to move closer to the curved workpiece, thereby controlling the curved workpiece to rotate, and then the motor 407 is started to limit the position of the curved workpiece by the movable plate 404 and the fixed plate 403, and then the electric telescopic rod 55 is started to move the pressure plate 56 away from the curved workpiece. By setting the arc plate 54, the electric telescopic rod 55 can be connected to the slide plate 51, and by setting the stabilizing plate 58, the working stability of the electric telescopic rod 55 can be increased. By setting the flipping device 5, the curved workpiece can be flipped during the inspection of the curved workpiece, so that different surfaces of the curved workpiece can be inspected, thereby maximizing the efficiency of inspecting the curved workpiece.
