The bottom of the moving block 804 is fixedly connected with the transmission block 803, and the bottom of the transmission block 803 is fixedly connected with the top of the visual inspection device 7, the inner lower end of the frame 1 is fixedly connected with the U-shaped frame 6, the bottom of the U-shaped frame 6 is fixedly connected with the bottom plate 3, a rotating motor 5 is fixedly installed on one side of the U-shaped frame 6, the output end of the rotating motor 5 is fixedly connected with the fixing plate 2, the surface of the fixing plate 2 is penetrated with a fixing groove 4, the inside of the fixing groove 4 is movably provided with a clamping plate 10, and the ends of the two clamping plates 10 close to each other are fixedly connected with anti-slip pads 11;

[0028] Specifically, Figure 1 , Figure 2 and Figure 4As shown, when it is used, when it is necessary to carry out inspection work on the parts to be inspected, the parts to be inspected are first placed horizontally in the fixed groove 4, and then the parts are fixed. After the fixing is completed, the threaded rod 805 can be driven to rotate by the output end of the first forward and reverse motor 802, and the threaded rod 805 rotates to drive the moving block 804 to move rightward. The moving block 804 moves rightward and drives the visual inspection device 7 to move rightward through the transmission block 803, thereby completing the inspection work on one side of the parts in the fixed groove 4. After the inspection of one side of the parts is completed, the rotating motor 5 is started, and the output end of the rotating motor 5 can be used to drive the fixed plate 2 to rotate. The rotation of the fixed plate 2 drives the parts in the fixed groove 4 to rotate. When the fixed plate 2 rotates to the horizontal position again, the rotating motor 5 is controlled to be turned off, and then the threaded rod 805 can be driven to rotate in the opposite direction through the output end of the first forward and reverse motor 802, and finally the visual inspection device 7 is driven to move to the left, so as to complete the inspection of the other side of the parts in the fixed groove 4.

[0030] Specifically, Figure 3 and Figure 5As shown, when in use, after the parts to be detected are placed in the fixing groove 4, the two bidirectional screws 902 can be driven to rotate simultaneously through the output ends of the two second forward and reverse motors 907, and the rotation of the two bidirectional screws 902 drives the two threaded blocks 906 on the bidirectional screws 902 to move in a direction close to each other, and the movement of the two threaded blocks 906 drives the two second hinge blocks 908 to move, and the two second hinge blocks 908 move through the cooperation of the first hinge block 903 and the connecting rod 909, and drive the transmission plate 904 to move in a direction close to the parts to be detected, and the two transmission plates 904 move through the transmission rod 905 to drive the two clamping plates 10 to move in a direction close to the parts to be detected until they contact the outer walls of the two ends of the parts to be detected and effectively fix them. By effectively fixing the parts to be detected, it is convenient to flip the parts to be detected later, thereby improving the detection efficiency, and by setting the anti-slip pad 11, the friction between the clamping plate 10 and the parts to be detected can be increased, thereby improving the fixing effect.

[0031] Working principle: In the present application, when it is necessary to carry out inspection work on the parts to be inspected, the parts to be inspected are first placed horizontally into the fixed groove 4, and then the output ends of the two second forward and reverse motors 907 can drive the two bidirectional screws 902 to rotate simultaneously, and the rotation of the two bidirectional screws 902 drives the two threaded blocks 906 on the bidirectional screws 902 to move in a direction close to each other, and the movement of the two threaded blocks 906 drives the two second hinge blocks 908 to move, and the movement of the two second hinge blocks 908 drives the transmission plate 904 to move in a direction close to the parts to be inspected through the cooperation of the first hinge block 903 and the connecting rod 909, and the two transmission plates 904 move through the transmission rod 905 to drive the two clamping plates 10 to move in a direction close to the parts to be inspected until they contact the outer walls of the two ends of the parts to be inspected and effectively fix them. After the fixation is completed, the threaded rod 805 can be driven to rotate through the output end of the first forward and reverse motor 802, and the rotation of the threaded rod 805 drives the moving block 804 to move to the right, and the moving block 804 moves to the right and drives the visual inspection device 7 to move to the right through the transmission block 803, thereby completing the inspection work on one side of the component in the fixed groove 4. When the inspection of one side of the component is completed, start the rotating motor 5, and the output end of the rotating motor 5 can be used to drive the fixed plate 2 to rotate, and the rotation of the fixed plate 2 drives the components in the fixed groove 4 to rotate. When the fixed plate 2 rotates to a horizontal position again, the rotating motor 5 is controlled to be turned off, and then the threaded rod 805 can be driven to rotate in the opposite direction through the output end of the first forward and reverse motor 802, and finally drive the visual inspection device 7 to move to the left, thereby completing the inspection work on the other side of the component in the fixed groove 4. The operation is simple and the inspection efficiency is high.
