[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Reference Figure 1-4 As shown, a metal surface defect visual inspection device comprises a mounting box 1 with an open top, a visual camera 2 arranged on the open end of the mounting box 1, and a lifting component for expanding a manual operation space, wherein a cover plate 3 detachably connected to the open end of the mounting box 1 by screws is attached to the top of the visual camera 2;

[0024] By setting the lifting component, when the cover plate 3 is removed, the visual camera 2 can be quickly extended outward from the opening of the installation box 1 under the action of the lifting component, so that the visual camera 2 is quickly exposed, effectively expanding the operating space.

[0025] Specifically, refer to Figure 2 As shown, it is worth noting that the lifting component includes a movable plate 4 slidably arranged inside the installation box 1 and an elastic lifting component arranged between the movable plate 4 and the inner wall of the bottom end of the installation box 1, and the visual camera 2 is installed on the top surface of the movable plate 4;

[0026] The elastic lifting assembly includes a fixed cylinder 5 with a cavity inside and vertically fixed on the inner wall of the bottom end of the installation box 1, a sliding plate 6 slidably arranged in the inner cavity of the fixed cylinder 5, and a telescopic rod 7 vertically fixed on one side of the sliding plate 6. The end of the telescopic rod 7 passes through the fixed cylinder 5 and is fixedly connected to the bottom surface of the movable plate 4. A compression spring 8 is fixedly connected between the other side of the sliding plate 6 and the inner wall of the bottom end of the fixed cylinder 5.

[0027] When the cover plate 3 and the installation box 1 are to be assembled, the cover plate 3 is fitted to the top of the visual camera 2 in advance, and then the cover plate 3 is pressed down, so that the visual camera 2 and the movable plate 4 are forced to shrink toward the inner cavity of the installation box 1 as a whole. In this process, the telescopic rod 7 pushes down the slide 6, causing the slide 6 to slide down in the inner cavity of the fixed tube 5 and compress the compression spring 8 to deform. After the cover plate 3 moves to fit the open end of the installation box 1, the cover plate 3 is then fastened to the open end of the installation box 1 with screws, so that the reverse thrust of the compression spring 8 on the slide 6, the telescopic rod 7, the movable plate 4 and the visual camera 2 can be offset, thereby ensuring the stability of the visual camera 2 in the inner cavity of the installation box 1;

[0028] The cover plate 3 and the mounting box 1 cooperate to provide a good sealing space for the visual camera 2, so as to prevent the visual camera from being exposed to dust or moisture and affecting the detection quality;

[0029] On the contrary, when the visual camera 2 is to be inspected and maintained, it is only necessary to simply loosen the screws on the cover plate 3 to release the fixing effect of the cover plate 3 on the open end of the installation box 1. The slide 6 can push the telescopic rod 7 and the movable plate 4 as a whole under the elastic force of the compression spring 8, so that the visual camera 2 can be quickly extended to the outside of the opening of the installation box 1, thereby expanding the manual operation space and facilitating manual inspection and maintenance of the visual camera 2.

[0030] Further, refer to Figure 1 , Figure 3 as well as Figure 4 As shown, it is worth noting that it also includes a bearing component for ensuring the stability of the visual camera 2 during inspection and maintenance;

[0031] By setting the bearing components, when the visual camera 2 is extended from the lifting component to the outside of the opening of the installation box 1, the bearing components can provide auxiliary support to the movable plate 4 from the bottom, thereby ensuring the stability of the movable plate 4 in the open end of the installation box 1, so as to prevent the movable plate 4 from being forced to move toward the inside of the installation box 1 during inspection and maintenance, thereby affecting the progress of the work.

[0032] Further, refer to Figure 1 , Figure 3 as well as Figure 4 As shown, it is worth noting that the bearing component includes a movable groove extending through the inner wall of the open end of the installation box 1, a bearing block 9 slidably arranged in the movable groove, and a magnetic attraction component arranged on the side of the cover plate 3. A plurality of slide grooves are arranged on the inner wall at the bottom end of the movable groove, and a rebound component cooperating with the bearing block 9 is arranged in the slide groove;

[0033] The rebound assembly includes a slider 10 which is slidably arranged inside the slide slot and fixedly connected to the bearing block 9, and a return spring 11 is fixed between the slider 10 and the inner wall of one side of the slide slot;

[0034] The magnetic attraction assembly includes a bonding plate 12 vertically bonded to the side wall of the installation box 1 and fixedly connected to the cover plate 3, a magnetic plate 13 is fixedly embedded on the side of the bonding plate 12 facing the installation box 1, and a magnetic block 14 bonded to the magnetic plate 13 is fixed on one end of the bearing block 9;

[0035] As shown above, when the cover plate 3 is attached to the top of the visual camera 2, the attaching plate 12 can be attached to the side wall of the installation box 1 simultaneously, so that the magnetic plate 13 corresponds to the magnetic block 14 and forms an attraction force on the magnetic block 14, and the bearing block 9 can be forced to quickly shrink inside the movable groove, without hindering the subsequent shrinking process of the movable plate 4 and the visual camera 2 as a whole into the installation box 1;

[0036] During the process of the supporting block 9 moving into the movable groove, the slider 10 can synchronously slide in the slide groove and stretch the reset spring 11 to deform. When the cover plate 3 is subsequently removed to allow the visual camera 2 to extend from the inside of the installation box 1, the fitting plate 12 is detached from the side wall of the installation box 1. In this way, the magnetic plate 13 no longer corresponds to the magnetic block 14, and the slider 10 can reset the supporting block 9 under the elastic force of the reset spring 11, so that the supporting block 9 penetrates into the inner cavity of the installation box 1 and fits with the bottom surface of the movable plate 4, thereby assisting in supporting the movable plate 4 from the bottom.

[0037] Further, refer to Figure 1 and Figure 2 As shown, it is worth noting that a perspective glass 15 is fixedly embedded in the inner wall of one side of the installation box 1, and the perspective glass 15 corresponds to the detection end of the visual camera 2;

[0038] By providing the perspective glass 15 , the perspective effect of the detection end of the visual camera 2 can be ensured without affecting the sealing inside the installation box 1 , so that the visual camera 2 can perform defect detection on the surface of the armature component conveniently.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
