DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4 , the present utility model discloses a positioning fixture for lamp processing, including a spraying table 1 and a lampshade 12. The spraying table 1 is rotatably connected with a rotating table 2. The top of the rotating table 2 is evenly provided with support rods 3 along its circumferential direction. A fixing ring 4 is fixedly sleeved on each support rod 3. Both sides of the outer wall of the fixing ring 4 are hinged with a first movable rod 5. One end of the first movable rod 5 is movably connected to an inner support plate 6 in a T - shape. The inner support plate 6 is used to tighten the lampshade 12. The inner support plate 6 is hinged with a second movable rod 7 hinged to the first movable rod 5. The second movable rod 7 is movably connected to a nut seat 8. The top of the support rod 3 is rotatably connected with a ball screw 9 that cooperates with the nut seat 8.

[0019] Specifically, a motor for driving the ball screw 9 to rotate is installed inside the support rod 3.

[0020] Specifically, an anti - detachment block 10 is fixedly connected to the top of the ball screw 9.

[0021] In this embodiment, when the ball screw 9 is driven to rotate, it can drive the nut seat 8 to displace. The setting of the anti - detachment block 10 can limit the maximum displacement of the nut seat 8.

[0022] Specifically, a support block 11 is installed at one end of the inner support plate 6 away from the support rod 3.

[0023] In this embodiment, the support block 11 can cooperate with the inner support plate 6 to support the lamp shade 12.

[0024] Specifically, a first movable cavity 13 and a second movable cavity 15 which are connected and arranged up and down are formed inside the spraying table 1. The first movable cavity 13 and the second movable cavity 15 are in a T - shape. The rotating table 2 is rotatably connected and protrudes outside the first movable cavity 13. The bottom of the rotating table 2 is connected to a support shaft 14 which is rotatably connected to the bottom inner wall of the second movable cavity 15.

[0025] A toothed ring 16 is fixedly sleeved on the support shaft 14, and a gear 17 driven by a motor and meshing with the toothed ring 16 is arranged in the second movable cavity 15.

[0026] In this embodiment, when the motor drives the gear 17 to mesh with the toothed ring 16 and rotate, it can drive the support shaft 14 to drive the rotating table 2 to rotate, so as to adjust the position of each lamp shade 12 tightened and limited by the inner support plate 6, facilitating the loading and unloading of the lamp shade 12.

[0027] In summary, for this positioning fixture for lamp processing, through the cooperation of the inner support plate 6, it can tension the inner cavity of the lamp shade, fix the lamp shade 12, without blocking the lamp shade 12, and facilitate the spraying of the lamp shade 12. By arranging a plurality of support rods 3 provided with inner support plates 6 on the rotating table 2, it can facilitate the loading and unloading of the lamp shade 12 during the processing.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
