Description

Technical Field

[0001] The utility model belongs to the technical field of lens processing, in particular to a tire lens processing device. Background Art

[0002] Tire lens is also called complex curved mirror or combination mirror. It has two different curvatures in the x direction and y direction, respectively, and is shaped in the two directions. If the surface is coated with a reflective film, it is mostly used for large-angle reflection of light. After reflection, there is no image deformation problem of ordinary plane reflectors and single spherical reflectors, which reduces the use of optical lenses. A complex curved reflector can replace a combination of multiple plane reflectors, spherical reflectors and cylindrical mirrors, reducing the volume of the optical system, making the optical system debugging more convenient and simple, and improving the performance of the optical system.

[0003] At present, in the industry, the processing of toric mirrors generally adopts the principle of profiling and uses CNC grinding machines for processing. This processing method is suitable for mass production, but not for small batch production. The difficulty in small batch production of toric mirrors is the difficulty in clamping the lenses. In particular, the clamp that clamps multiple lenses at the same time needs to use a pressure fixing rod to press the lenses on the mold for fixing. If the pressure fixing rod is loosened, the lenses will fall off. At the same time, using this clamp requires a lot of preparation work before processing, and there is a problem of low processing efficiency.

[0004] The patent with publication number CN219026980U discloses a combined fixture and a complex curved mirror processing device containing the combined fixture. The stability of the processing is ensured by setting two fixtures for combination. However, in the fixture of this structure, the second cylindrical fixture is inserted into the first cylindrical fixture, and the lens is directly placed in the groove on the second cylindrical fixture. When in use, the second cylindrical fixture and the lens need to be supported, and then the lens is pressed against the mold by a pressure fixing rod. The use of this fixture to process complex curved mirrors has the problem of easy lens falling and low work efficiency. Utility Model Content

[0030] The main body 1 is provided with a clamping hole 13 on both sides of the bottom in the mounting groove 12, and a connecting hole 20 and a movable hole 17 are provided on both side walls of the main body 1, wherein the movable hole 17 is communicated with the clamping hole 13; the main body 1 is connected with the movable hole 17 through the mounting hole, and a clamping joint 16 is provided at the bottom of the mounting member 9; the mounting member 9 is provided with a negative pressure hole 6 at the bottom of the positioning groove 7, and the main body 1 is provided with an air intake hole 11 aligned with the negative pressure hole 6 at the bottom of the mounting groove 12;

[0031] The clamping part includes a connecting plate 3, a pull ring 4, a connecting column 19 and a movable column 15; the movable column 15 is fixedly connected to one side of the connecting plate 3, and the pull ring 4 is fixedly connected to the other side; the connecting column 19 is fixedly connected to the connecting plate 3 and is located on both sides of the movable column 15; the movable column 15 is movably connected to the movable hole 17, and the connecting column 19 is movably connected to the connecting hole 20; the end of the movable column 15 extends into the clamping hole 13, and the end of the movable column 15 is a trapezoidal structure with the inclined surface facing upward; a trapezoidal clamping groove 2 is provided on one side of the clamping joint 16 close to the bottom; a tension spring 18 is provided in the connecting hole 20, and the two ends of the tension spring 18 are respectively connected to the connecting column 19 and the main body 1.

[0032] Specifically, when in use, it is necessary to cooperate with a mold, a pressurized fixing rod, an air pump and a polishing machine. It should be noted that the above structures all adopt existing technologies, so the specific structure will not be repeated here. First, insert the mounting member 9 into the mounting groove 12, and the clamping joint 16 at the bottom of the mounting member 9 enters the inside of the clamping hole 13. Press the mounting member 9 downward so that the clamping joint 16 squeezes the inclined surface of the movable column 15. After being squeezed, the movable column 15 moves outward and drives the connecting plate 3 to move outward. The connecting plate 3 drives the connecting column 19 to move outward, and the connecting column 19 causes the tension spring 18 to extend. After the movable column 15 completely withdraws from the clamping hole 13, the clamping joint 16 can be inserted into the bottom of the clamping hole 13. After the clamping joint 16 is inserted into the bottom of the clamping hole 13, the tension spring 18 drives the connecting column 19 to reset, the connecting column 19 drives the connecting plate 3 to reset, the connecting plate 3 drives the movable column 15 to reset, the end of the movable column 15 is inserted into the clamping groove 2 at the bottom of the clamping joint 16 and fixes the position of the clamping joint 16. After the position of the clamping joint 16 is fixed, the mounting member 9 is also fixed. After the position of the mounting member 9 is fixed, the negative pressure hole 6 and the air suction hole 11 are connected. The lens is installed in the positioning groove 7. An air pump is used to suck air from the air suction hole 11 and form a negative pressure in the negative pressure hole 6 and the positioning groove 7. The negative pressure environment in the positioning groove 7 causes the lens to be close to the mounting member 9, and the lens can be stably fixed by this design. Multiple lenses can be clamped simultaneously by the mounting member 9, the stability of the mounting member 9 can be maintained by the clamping joint 16, and the position of the lens can be stabilized by creating a negative pressure environment. Then, the processing device of the present application is pressed onto the mold as a whole by using a pressurized fixing rod, and the pressurized fixing rod drives the processing device to move relative to the mold along the Y-axis direction, and the polishing machine allows the lens to be processed and the mold to move in the X-axis and Y-axis directions at the same time, thereby completing the processing of the complex surface. It should also be noted that the present application can process multiple lenses at the same time. When processing multiple lenses at the same time, the specifications of the multiple lenses can be consistent or inconsistent. If it is necessary to ensure that the curvature of multiple lenses is consistent, it is necessary to make the central axis of the circular positioning groove 7 on the mounting member 9 perpendicular to the surface of the mounting member.

[0033] In a preferred embodiment, Figures 1 to 4 As shown, the curvature of the arc structure on the main body is the same as the curvature required to be achieved in the X-axis direction of the lens. Further optimized, the curvature of the arc structure on the mounting member 9 is the same as the curvature required to be achieved in the Y-axis direction of the lens. Specifically, the main body and the mounting member 9 are both replaceable structures, and the corresponding main body and mounting member 9 can be selected according to actual needs. The main body and the mounting member 9 are designed in this way to ensure the accuracy of lens processing.

[0034] In a preferred embodiment, if Figures 1 to 4As shown, a plurality of clamping posts 14 are provided on the side wall of the mounting groove 12, and a clamping slot that cooperates with the clamping posts 14 is provided at the bottom of the side wall of the mounting member 9. When the mounting member 9 is inserted into the mounting groove 12, the clamping slot and the clamping posts 14 cooperate to prevent the mounting member 9 from shaking. Because in the actual processing process, it cannot be guaranteed that the mounting member 9 and the mounting groove 12 are perfectly fitted, it is necessary to stabilize the position of the mounting member 9 through the design of the clamping posts 14 and the clamping slots.

[0035] In a preferred embodiment, if Figures 1 to 4 As shown, a sealing groove 10 is provided on the mounting member 9 at the top edge of the positioning groove 7, and a sealing ring 5 is provided in the sealing groove 10. The sealing groove 10 and the sealing ring 5 are used to ensure the sealing between the lens and the mounting member 9, so that the lens can be stably adsorbed on the positioning groove 7. At the same time, the sealing ring 5 is relatively soft and can protect the lens and prevent the lens from being crushed.

[0036] In a preferred embodiment, if Figures 1 to 4 As shown, the mounting member 9 is provided with an air hole 8, and the positioning grooves 7 are interconnected through the air hole 8. Multiple positioning grooves 7 are connected through the air hole 8. With this design, only one negative pressure hole 6 is required on the mounting member 9, which reduces the number of air intake holes 11 on the main body. One air intake hole 11 and one negative pressure hole 6 are used to draw air from all the positioning grooves 7 on the mounting member 9 to form negative pressure.

[0037] In a preferred embodiment, if Figures 1 to 4 As shown, the bottom of the mounting member 9 is provided with a circle of notches on the outside of the negative pressure hole 6, and a sealing rubber ring is provided in the notch. The design of the notch and the sealing rubber ring can improve the sealing between the negative pressure hole 6 and the air intake hole 11.

[0038] In a preferred embodiment, if Figures 1 to 4 As shown, at least two mounting grooves 12 are provided on the main body. In the present application, three mounting grooves 12 are provided, that is, three mounting members 9 can be installed on one main body. By simultaneously providing multiple mounting members 9, multiple lenses can be processed simultaneously, thereby improving the processing efficiency. Further optimized, at least two positioning grooves 7 are provided on the mounting member 9, and the positioning grooves 7 are evenly spaced on the mounting member 9. Specifically, in the embodiment, three positioning grooves 7 are provided on each mounting member 9. By providing multiple positioning grooves 7, multiple lenses can be installed on one positioning member, that is, the number of lenses processed simultaneously is further increased, which can effectively improve the processing efficiency.
