[0032] As Figures 1 - 4 shown, a lamp shade clamping fixture includes: a base 1, a rotating seat 2, a rotating frame 3, and a clamping assembly 4.

[0033] Among them, the rotating seat 2 is provided with a rotating upper seat 21 and a rotating lower seat 22. The rotating upper seat 21 is rotatably connected to the rotating lower seat 22, and the rotating lower seat 22 is connected to the base 1.

[0034] Among them, the rotating frame 3 is connected to the rotating upper seat 21.

[0035] Among them, the number of the clamping assemblies 4 is two, and both of the two clamping assemblies 4 are connected to the rotating frame 3 in a liftable manner.

[0036] Specifically, the rotating frame 3 is rotatably connected to the base 1 through the rotating seat 2, and the clamping assemblies 4 are connected to the rotating frame 3 in a liftable manner. After the two clamping assemblies 4 clamp the lamp shade, the position of the lamp shade is adjusted.

[0037] In this embodiment, after the lamp shade is clamped by the clamping assembly 4, the angle and height of the lamp shade can be adjusted as needed, so that it can flexibly adapt to lamp shades of different specifications for corresponding quality inspection, improving the versatility and efficiency of the inspection process.

[0038] As Figures 1 - 4As shown, on the basis of the above-described embodiment, the clamping assembly 4 includes a first clamping rod 41, a second clamping rod 42, and a first fastener 43. The head of the first fastener 43 can contact the second clamping rod 42, and the tail of the first fastener 43 can pass through the second clamping rod 42 and be threadedly connected to the first clamping rod 41.

[0039] Specifically, the tail of the first fastener 43 can pass through the second clamping rod 42 and be threadedly connected to the first clamping rod 41. When the first fastener 43 is rotated, the head of the first fastener 43 can approach or move away from the first clamping rod 41, thereby pushing the second clamping rod 42 closer to or away from the first clamping rod 41, and further clamping or disassembling the lamp cover.

[0040] In this embodiment, by adjusting the first fastener 43 to adjust the distance between the first clamping rod 41 and the second clamping rod 42, it is possible to easily adapt to lamp covers of different thicknesses. The operator can conveniently and quickly make fine adjustments according to the specific size of the lamp cover to ensure that the lamp cover can be firmly and properly clamped.

[0041] As Figures 1 - 4 shown, on the basis of the above-described embodiment, the number of the first fasteners 43 is two. The heads of the two first fasteners 43 can respectively contact the two ends of the second clamping rod 42, and the tails of the two first fasteners 43 can respectively pass through the second clamping rod 42 and be threadedly connected to the two ends of the first clamping rod 41.

[0042] In this embodiment, the two first fasteners 43 are provided at the two ends of the second clamping rod 42 and the first clamping rod 41, so as to be able to finely adjust the balance of the distances on both sides between the second clamping rod 42 and the first clamping rod 41, and fully clamp the lamp cover without damaging the lamp cover.

[0043] As Figures 1 - 4 shown, on the basis of the above-described embodiment, the clamping assembly 4 further includes a second fastener 44 and a slider 45. The rotating frame 3 is provided with a sliding groove 31. The head of the second fastener 44 can contact the first clamping rod 41, the tail of the second fastener 44 can pass through the first clamping rod 41 and be threadedly connected to the slider 45, and the slider 45 can move in the sliding groove 31.

[0044] Specifically, the slider 45 is slidably disposed in the sliding groove 31. After the clamping assembly 4 moves to a suitable height, the distance between the first clamping rod 41 and the slider 45 can be reduced by rotating the fastener until the slider 45 contacts the side wall of the sliding groove 31, thereby fixing the position of the first clamping rod 41 and further fixing the height of the clamping assembly 4.

[0045] In this embodiment, by adjusting the heights of the two clamping assemblies 4, it is possible to adapt to lamp shades of different sizes and adjust the height of the entire lamp shade. The position of the clamping assembly 4 can be quickly adjusted according to the specific dimensions of the lamp shade, so as to ensure that the lamp shade can obtain the best light irradiation angle during the detection process, and then complete the comprehensive detection in terms of light transmittance, size, shape, surface quality, etc.

[0046] As Figures 1 - 4 shown, on the basis of the above embodiment, the number of the second fasteners 44, the sliders 45 and the sliding grooves 31 is two. The heads of the two second fasteners 44 can respectively contact the two ends of the first clamping rod 41, and the tails of the two second fasteners 44 can respectively pass through the first clamping rod 41 and be threadedly connected to the sliders 45. The two sliders 45 can respectively move in the two sliding grooves 31.

[0047] Specifically, the sliding grooves 31 are located on both sides of the rotating frame 3 and are arranged in parallel, so that the clamping assembly 4 can smoothly move up and down following the sliders 45.

[0048] In this embodiment, by sliding the sliders 45 in the sliding grooves 31, the height of the clamping assembly 4 is controlled. The structure is simple and not easily damaged, and the operation is simple and convenient, and it can quickly adapt to different lamp shade sizes and different detection heights.

[0049] As Figures 1 - 4 shown, on the basis of the above embodiment, the rotating frame 3 includes a rotating outer frame 32 and a rotating inner frame 33. The rotating outer frame 32 is rotatably connected to the rotating upper seat 21, the rotating inner frame 33 is movably connected to the rotating outer frame 32, and the two clamping assemblies 4 are both liftably connected to the rotating inner frame 33.

[0050] Specifically, the rotating outer frame 32 is rotatably connected to the rotating inner frame 33, which enables the quality of the lamp shade at different irradiation angles to be detected by rotating the lamp shade while keeping the positions of tools for detecting the lamp shade, such as spotlights, unchanged.

[0051] In this embodiment, without moving the detection device, the lamp shade is irradiated by light from multiple directions, so as to comprehensively evaluate the light transmittance, reflection effect and any possible defects of the lamp shade under different lighting conditions, such as air bubbles, scratches, etc. This design simplifies the detection process and improves the detection efficiency.

[0052] As Figures 1 - 4As shown, on the basis of the above-described embodiment, the rotating inner frame 33 is provided with a rotating block 331 and a moving block 332. The moving block 332 is fixedly connected to the rotating inner frame 33. The rotating block 331 is movably connected to the moving block 332. The rotating inner frame 33 is rotatably connected to the rotating outer frame 32 through the rotating block 331.

[0053] Specifically, the moving block 332 is movably connected to the rotating block 331, so that the rotating inner frame 33 for clamping the lamp shade can move relative to the fixed rotating inner frame 33 successively, thereby controlling the distance between the lamp shade and the detection tool.

[0054] In this embodiment, the distance between the moving block 332 and the rotating block 331 can be adjusted, so that the rotating inner frame 33 can be moved back and forth, and the distance between the lamp shade to be measured and the detection tool can be controlled.

[0055] As Figures 1 - 4 shown, on the basis of the above-described embodiment, an adjusting rod 333 is further included. The adjusting rod 333 is rotatably connected to the rotating block 331. The adjusting rod 333 is threadedly connected to the moving block 332.

[0056] Specifically, the adjusting rod 333 is rotatably connected to the rotating block 331. When the adjusting rod 333 rotates, the moving block 332 threadedly connected to the adjusting rod 333 can move back and forth along the length direction of the adjusting rod 333.

[0057] In this embodiment, by threadedly connecting the adjusting rod 333 to the moving block 332, the rotational movement of the moving block 332 is converted into a movement along the direction of the adjusting rod 333. The operation of adjusting the front and rear positions of the moving block 332 is simple, and the accuracy and stability are high through threaded adjustment.
