DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides a visual inspection device for automotive nuts as shown in Figures 1-4 Figure 1, which includes a fixing frame 1. A camera 2 is arranged at the top of the fixing frame 1. A light source 3 is arranged on one side of the fixing frame 1. An installation frame 4 for installing the light source 3 is fixedly connected to one side of the fixing frame 1. A base 6 is fixedly connected to the bottom end of the light source 3. A connecting piece 7 is arranged at the connection between the base 6 and the installation frame 4; The connecting piece 7 includes a limiting block 701 symmetrically and fixedly connected to the bottom end of the base 6. A limiting groove 702 is symmetrically opened at the center of the top end of the installation frame 4. A clamping piece 8 for restricting the movement of the limiting block 701 is arranged inside the limiting groove 702. The clamping piece 8 includes a clamping block 801. A driving piece 9 for driving the clamping block 801 to move is arranged on one side of the clamping block 801. The limiting block 701 is inserted into the inside of the limiting groove 702. The clamping piece 8 further includes a clamping groove 802 opened in the middle of the limiting block 701. The clamping block 801 is clamped inside the clamping groove 802.

[0023] It should be noted that the selection and configuration of the light source 3 depend on the specific requirements of the inspection, such as surface defect inspection or dimension measurement. When in use, the nut is irradiated by the uniform light source 3 to ensure clear image acquisition; The arranged camera 2 is used to capture the image of the nut. When in use, a high-resolution industrial camera is used to obtain an image with sufficient details; The arranged base 6 is fixed to the bottom end of the light source 3 by bolts. The arranged base 6 and the arranged limiting block 701 are fixed to the bottom end of the base 6, and the number of the limiting blocks 701 is two. Two limiting grooves 702 adapted to the limiting blocks 701 are opened at the top end of the installation frame 4. When in use, it is used to insert the limiting blocks 701 into the inside of the limiting grooves 702; One end of the clamping block 801 is inserted into the inner wall of one side of the limiting groove 702, and the length of the horizontal longitudinal section of the clamping block 801 is greater than the length of the horizontal longitudinal section of the limiting groove 702. When the clamping block 801 is inserted into the inside of the limiting groove 702, a part of the clamping block 801 is still inserted into the inner wall of one side of the limiting groove 702. The clamping groove 802 opened in the middle of the limiting block 701 is adapted to the arranged clamping block 801 and is used to insert the clamping block 801 into the inside of the clamping groove 802.

[0024] It should be noted that the reference numeral "Figure 1" in the translation of item is assumed because the original text seems to be missing the specific figure reference. If there is an actual figure number in the original that is not "1", it should be corrected accordingly.Further, when it is necessary to fix the position of the light source 3, first fix the base 6 to the bottom end of the light source 3 through bolts, then move the light source 3 and the base 6 to the top end of the mounting bracket 4, align the limiting block 701 on the base 6 with the limiting slot 702 at the top end of the mounting bracket 4, drive the clamping block 801 out of the limiting slot 702 by the driving member 9, and insert the limiting block 701 into the inside of the limiting slot 702, so that the clamping slot 802 on the limiting block 701 is aligned with the clamping block 801, and then drive the clamping block 801 to move by the driving member 9, so that the clamping block 801 moves into the inside of the clamping slot 802. Due to the restriction of the clamping block 801, the limiting block 701 cannot move out of the limiting slot 702, thereby fixing the position of the limiting block 701, and fixing the positions of the base 6 and the light source 3 through the limiting block 701 with a fixed position; when it is necessary to disassemble and maintain the light source 3, directly drive the clamping block 801 out of the clamping slot 802 and the limiting slot 702 by the driving member 9, and then take out the limiting block 701 from the limiting slot 702, thereby completing the disassembly of the light source 3.

[0025] Specifically, the driving member 9 includes a driving block 901 fixedly connected to one side of the clamping block 801. The bottom end of the driving block 901 is fixedly connected to a connecting block 902. One end of the connecting block 902 is fixedly connected to a pressing block 903 for driving the connecting block 902 to move. The driving member 9 further includes a spring 904 disposed on one side of the pressing block 903. A receiving groove 10 is formed on one side of the mounting bracket 4. The pressing block 903 and the spring 904 are both inserted into the inside of the receiving groove 10. A connecting groove 11 is formed on the inner wall of one side of the receiving groove 10. The connecting block 902 is inserted into the inside of the connecting groove 11. A plurality of sliding grooves 5 are symmetrically formed at the center of the inner wall of the top end of the connecting groove 11. The driving block 901 is inserted into the inside of the sliding grooves 5. The clamping block 801 is inserted into the inner wall of one side of the sliding grooves 5.

[0026] It should be noted that the formed receiving groove 10 is adapted to the provided pressing block 903. The pressing block 903 is inserted into the inside of the receiving groove 10. One end of the provided spring 904 is fixedly connected to the inner wall of one side of the receiving groove 10, and the other end of the spring 904 is fixedly connected to one side of the pressing block 903. When in use, it is used to push the pressing block 903 to the side away from the receiving groove 10. When the spring 904 drives the pressing block 903 to move to the side away from the receiving groove 10, the pressing block 903 drives the connecting block 902 and the driving block 901 to move. When the driving block 901 moves to fit with the inner wall of one side of the sliding groove 5, when the driving block 901 cannot move continuously, the movement of the connecting block 902 and the pressing block 903 is restricted by restricting the movement of the driving block 901.

[0027] Further, when it is necessary to move the clamping block 801 out of the limiting groove 702, press the pressing block 903 towards one side of the receiving groove 10. The spring 904 is squeezed and deformed. The connecting block 902, the driving block 901 and the clamping block 801 are driven to move through the pressing block 903, so as to move the clamping block 801 out of the limiting groove 702. When it is necessary to move the clamping block 801 into the limiting groove 702, release the pressing on the pressing block 903. The spring 904 resumes deformation and pushes the pressing block 903 towards the side away from the spring 904, and drives the connecting block 902, the driving block 901 and the clamping block 801 to move through the pressing block 903, so that the end of the clamping block 801 moves into the limiting groove 702.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
