[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0021] The utility model provides a technical solution: Figure 1 and Figure 2 As shown, in this embodiment, a clamping device for producing projection lamp lenses includes a fixed bottom plate 1, a mounting vertical plate 2 is symmetrically installed on the top surface of the fixed bottom plate 1, a limit rod 3 is symmetrically arranged on the inner side of each mounting vertical plate 2, one end of the limit rod 3 is rotatably connected to the mounting vertical plate 2, the cross section of the limit rod 3 is "L"-shaped, a limit slot 4 is provided on the inner surface of the end of the limit rod 3, an adjustment component is provided at the bottom of the outer surface of one of the mounting vertical plates 2, the adjustment component includes a limit slider 6 fixed to the bottom end surface of one of the mounting vertical plates 2, a moving groove 5 for the limit slider 6 to move is provided at one end of the top surface of the fixed bottom plate 1, the cross section of the limit slider 6 is inverted "T" shape, and the bottom end surface of the limit slider 6 It is fitted and connected with the inner bottom surface of the movable groove 5, and a fixing groove 8 is opened at the bottom of the outer surface of the mounting vertical plate 2. A limiting plate 7 is installed at the temporal part of the fixing groove 8. The cross section of the limiting plate 7 is an inverted "L" shape. One end of the limiting plate 7 extends to the outside of the fixing groove 8. A limiting spring 9 is fixed between the top surface of the limiting plate 7 and the inner top surface of the fixing groove 8. A limiting rack 11 is evenly arranged on the bottom end surface of the limiting plate 7. The inner bottom surface of the movable groove 5 is evenly provided with connecting tooth grooves 10 for the engagement of the limiting rack 11, which is convenient for adjusting the distance between the two mounting vertical plates 2. It is simple and easy to operate, so that the clamping device can limit and clamp some lenses with smaller diameters, thereby improving applicability and good practicality.
[0022] like Figure 3 and Figure 4As shown, a protective component is arranged inside the limiting slot 4, and the protective component includes a protective sheet 12 arranged inside the limiting slot 4, and the inner wall of the limiting slot 4 is symmetrically provided with mounting slots 14 for engaging the two ends of the protective sheet 12, and limiting strips 15 are symmetrically fixed at the two ends of the protective sheet 12, and the longitudinal section of the end of the limiting strip 15 is circular, and the longitudinal section diameter of the limiting strip 15 is larger than the width of the opening of the mounting slot 14, and the protective sheet 12 is made of rubber material, and an elastic sheet 13 is arranged on the inner surface of the protective sheet 12, and the elastic sheet 13 is bonded to the protective sheet 12, so as to protect the inside of the limiting slot 4, so that the lens will not be squeezed and worn when it is engaged with the limiting slot 4, and it is also convenient to improve the stability of the lens when clamping, so that the lens is not easy to fall off during the processing, and the practical effect is better.
[0023] When the distance between the two mounting uprights 2 is adjusted appropriately, one end of the limiting plate 7 can be loosened, and the rebound force generated by the limiting spring 9 can act on the limiting plate 7, so that the limiting rack 11 on the bottom end surface of the limiting plate 7 can be separated from the inside of the connecting tooth groove 10 at the bottom of the inner side of the moving groove 5. Then, one of the mounting uprights 2 can be pushed to move on the top surface of the fixed bottom plate 1. At this time, the mounting uprights 2 can drive the limiting slider 6 to slide inside the moving groove 5 until the distance between the two mounting uprights 2 is adjusted appropriately. Then, one end of the limiting plate 7 can be loosened, and the rebound force generated by the limiting spring 9 can act on the limiting plate 7, so that the limiting rack 11 on the bottom end surface of the limiting plate 7 can be limitedly engaged with the corresponding connecting tooth groove 10, at this time, workers can limit and clamp some lenses with smaller diameters, which is convenient and quick to operate, with improved applicability and good practicality. When clamping the lens, the utility model first pushes the lens to move between the four limit rods 3, so that the edge of the lens is engaged with the inside of the limit slot 4. At this time, the lens will squeeze the protective sheet 12, thereby causing the protective sheet 12 to deform. At this time, the surface of the elastic sheet 13 will gradually approach the inner surface of the limit slot 4. At the same time, the two ends of the protective sheet 12 will also move to the outside of the installation slot 14, until the limit strips 15 at both ends of the protective sheet 12 are limited and engaged to the opening of the installation slot 14. At this time, the surface of the protective sheet 12 will be squeezed and fitted with the surface of the lens, which can protect the lens and prevent the lens from being worn by the inner wall of the limit slot 4 due to excessive squeezing force. At the same time, it is also convenient to improve the stability of the lens when clamping, and the practical effect is good.
