[0023] An automobile lamp cover detection device, referring to Figures 1-3 , includes a detection table 1, a spotlight 2 is arranged at one end of the detection table 1, a back plate 3 is arranged at the other end, and a clamping mechanism for clamping the lamp cover is arranged on the detection table 1 between the spotlight 2 and the back plate 3. The clamping mechanism includes a vertical plate 41 arranged on the detection table 1. A through circular groove 42 is formed on the vertical plate 41. A plurality of moving holes 43 are arranged around the circumferential side of the circular groove 42 on the vertical plate 41. An installation plate 44 is slidably arranged in each moving hole 43. A pressing plate 45 is hinged on the installation plate 44. An elastic member 46 is arranged between the pressing plate 45 and the installation plate 44. The pressing plate 45 presses the edge of the lamp cover against the installation plate 44 under the action of the elastic member 46.

[0024] Further, the moving hole 43 is a strip-shaped hole.

[0025] Further, a connecting rod 5 is arranged on the side of the installation plate 44 away from the pressing plate 45. One end of the connecting rod 5 passes through the moving hole 43 and is externally threaded with an anti-detaching cap 6.

[0026] Further, the elastic member 46 is a spring.

[0027] Further, sliding grooves 7 are symmetrically arranged on the detection table 1, and a slider 8 slidably matched with the sliding grooves 7 is arranged at the lower end of the back plate 3.

[0028] Further, the number of the moving holes 43 is 4.

[0029] The working principle of the present utility model is:

[0030] The assembled automobile lamp cover detection device is as Figure 1As shown in the figure, place the car lamp cover on the vertical plate 41 of the clamping mechanism. Then, first move the mounting plate 44. Since the pressing plate 45 is hinged on the mounting plate 44, the pressing plate 45 will move synchronously with the mounting plate 44 during the movement. Since an elastic member 46 is provided between the mounting plate 44 and the pressing plate 45, at this time, only need to rotate the pressing plate 45 to increase the distance between one end of the pressing plate 45 and the mounting plate 44. At this time, the elastic member 46 is in a stretched state. Then, place the edge of the lamp cover on the mounting plate 44 and release the pressing plate 45. Since the elastic member 46 resumes deformation, the elastic member 46 drives the pressing plate 45 to move towards the mounting plate 44 until the pressing plate 45 presses tightly on the edge of the lamp cover. Since a connecting rod 5 is provided on the side of the mounting plate 44 away from the pressing plate 45, and one end of the connecting rod 5 passes through the movable hole 43 and is threadedly connected with an anti-loosening cap 6, at this time, only need to tighten the anti-loosening cap 6 to fix the position of the connecting rod 5 on the movable hole 43. As Example 1, the present application takes 4 movable holes 43 as an example to illustrate the design concept of the present application. As Figure 1 shown, the 4 movable holes 43 are arranged around the circumference of the circular groove 42. The clamping principle of the mounting plate 44 of the 4 movable holes 43 on the edge of the lamp cover is the same, so the design principles of the other 3 are not described in detail herein. As Example 1, the movable hole 43 can be selected as a strip-shaped hole. The setting of the strip-shaped hole can be applicable to lamp cover edges of different widths. The circular groove 42 of the present application can also be a groove of other shapes, as long as it is adapted to the lamp cover, but the groove must be through, so that the light emitted by the spotlight 2 can pass through the lamp cover and fall on the back plate 3.

[0031] After the lamp cover is installed, turn on the spotlight 2 to ensure that the light emitted by the spotlight 2 can pass through the lamp cover and fall on the back plate 3. At this time, the inspector can observe whether there are cracks in the lamp cover from one side of the spotlight 2, and observe whether there are light spots or light leakage on the lamp cover from the back plate 3. During the process of observing the back plate 3, the inspector can further adjust the position of the back plate 3 to facilitate clearly observing the light spots or light leakage on the lamp cover.

[0032] In the above technology, in order to realize the movement of the back plate 3 on the inspection table 1, a slider 8 is provided at the lower end of the back plate 3, and a chute 7 for the slider 8 to slide fit is opened on the inspection table 1.

[0033] In order to solve the problems of shaking or falling of the lamp cover clamped by clips in the prior art, a vertical plate 41 is provided on the inspection table 1, and a plurality of strip-shaped holes are provided on the vertical plate 41. Each strip-shaped hole is provided with a mounting plate 44 and a pressing plate 45. Through the pressing action of the pressing plate 45 on the edge of the lamp cover, multiple acting points can appear on the edge of the lamp cover. With this setting, the problem that the lamp cover is not easy to shake or fall under external force is solved, thus ensuring the detection effect of the lamp cover.

[0034] Although the present utility model has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that various changes or modifications can be made to the present utility model without departing from the principle and spirit scope defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used for explanation, rather than for limiting the present utility model, and the scope of protection is defined by the content of the claims.
