Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical lens processing technology, and in particular to a mirror positioning fixture. Background Technology
[0002] The optical lens manufacturing process includes: material selection and pretreatment, blank forming, cutting and rounding, rough grinding and fine grinding, polishing, edging, coating, bonding, ink application, cleaning, inspection, and packaging. Key processes require controlling nanometer-level surface precision, and automated testing ensures accuracy of parameters such as refractive index, ultimately meeting the imaging requirements of the optical system.
[0003] Currently, a Chinese patent discloses a multi-angle adjustable optical lens processing fixture (authorization announcement number CN222779454U). The fixture uses a positioning component to facilitate the adjustment of the distance between two sets of first adjustment components according to the thickness of the lens. The first adjustment component can also be adjusted according to the curvature of the optical lens, and the second adjustment component can adjust the direction of the positioning stand according to the processing requirements for observation. Compared with traditional clamping methods, this fixture uses a curved surface fitting method, which not only firmly fixes the lens to ensure that it will not move during processing, but also makes it easier to observe or inspect the side of the lens for precise processing.
[0004] Since the circular slide rails and vertical bracket grooves used for auxiliary adjustment of the above-mentioned equipment are exposed, when the furniture is being sanded or polished, which will generate debris, the debris can easily enter the grooves. This will affect the user's subsequent adjustment of the clamps, resulting in low practicality. Utility Model Content
[0005] Therefore, it is necessary to provide a mirror positioning fixture to address the problem of low self-protection performance of existing mirror positioning fixtures for optical lenses.
[0006] A mirror positioning fixture, comprising:
[0007] Mounting base, the top of which is fitted with a mounting plate;
[0008] An angle adjustment mechanism, comprising an annular slide rail fixedly connected to the bottom of the mounting plate, an electric adjustment component embedded inside the annular slide rail, and an adjustment frame fixedly connected to the bottom of the electric adjustment component;
[0009] A locking mechanism is provided, comprising a lower suction cup clamp and an electric cylinder. The lower suction cup clamp and the electric cylinder are respectively fixedly connected to opposite ends of the adjusting frame. An upper suction cup clamp is fixedly connected to the end of the output shaft of the electric cylinder, which is positioned directly above the lower suction cup clamp. A rubber corrugated tube is fixedly connected between the upper suction cup clamp and the electric cylinder, and the rubber corrugated tube is sleeved on the outside of the output shaft of the electric cylinder.
[0010] In one embodiment, the electric adjustment assembly includes an internal gear ring rotatably connected inside an annular slide rail. The bottom of the internal gear ring is fixedly connected to an adjustment frame.

[0011] In one embodiment, a protective cover is fixedly connected inside the annular slide rail, and the spur gear and the output shaft of the servo motor are both arranged inside the protective cover.
[0012] In one embodiment, the vertical cross-sectional shape inside the annular slide rail and the vertical cross-sectional shape of the internal gear ring are both inverted convex shapes.
[0013] In one embodiment, the vertical cross-sectional shape of the adjustment frame is a "√" shape, and the partial cross-sectional shape of the connection part between the adjustment frame and the lower suction cup fixture and the electric cylinder is a "丨" shape.
[0014] In one embodiment, the ratio of the distance between the lower suction cup fixture and the upper suction cup fixture, the maximum extension length of the output shaft of the electric cylinder, and the maximum extension length of the rubber bellows is 1:2:3.
[0015] In one embodiment, the minimum inner diameter of the rubber bellows is greater than the diameter of the output shaft of the electric cylinder.
[0016] In one embodiment, a blocking ring is fixedly connected to the bottom of the mounting disc, and the annular slide rail is arranged inside the blocking ring.
[0017] Beneficial effects
[0018] The above-mentioned mirror positioning fixture forms multiple protections through the inverted convex shape engagement of the annular slide rail and the internal gear ring and in cooperation with the protective cover and the blocking ring, effectively isolating debris and cutting fluid, ensuring stable and precise angle adjustment driven by the servo motor; the rubber bellows wraps the output shaft of the electric cylinder and forms a dynamic seal with the upper suction cup fixture, preventing debris from invading the screw structure of the electric cylinder, extending the service life of the driving components and improving the clamping stability.
[0019] The adoptable replaceable lower suction cup fixture and upper suction cup fixture can not only reduce the probability of the surface of the optical lens being scratched during the clamping and fixing process, but also adapt to optical lenses with different curvatures and different sizes, realizing high-precision positioning and meeting the processing requirements of multiple processes.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0032] The following is combined Figures 1-4 This invention describes a mirror positioning fixture.
[0033] In one embodiment, a mirror positioning fixture includes: a mounting base 100, an angle adjustment mechanism 300, and a locking mechanism 400. A mounting plate 200 is mounted on the top of the mounting base 100, and bolt mounting holes are provided on the lower surface of the mounting base 100. Workers can lock the mounting base 100 at the corresponding processing position through bolts and bolt mounting holes.
[0034] like Figure 2 , Figure 3 and Figure 4As shown, the angle adjustment mechanism 300 includes an annular slide rail 310 fixedly connected to the bottom of the mounting plate 200. An electric adjustment component 320 is embedded and installed inside the annular slide rail 310. The bottom of the electric adjustment component 320 is fixedly connected to an adjustment frame 330. The electric adjustment component 320 includes an internal gear ring 321 rotatably connected inside the annular slide rail 310. The bottom of the internal gear ring 321 is fixedly connected to the adjustment frame 330. A spur gear 322 is meshed and connected to the inner side of the internal gear ring 321. The bottom of the spur gear 322 is fixedly connected to a servo motor 323 fixedly connected to the annular slide rail 310. A protective cover 324 is fixedly connected to the inner side of the annular slide rail 310. The output shafts of the spur gear 322 and the servo motor 323 are both arranged inside the protective cover 324. The vertical cross-sectional shape inside the annular slide rail 310 and the vertical cross-sectional shape of the internal gear ring 321 are both inverted convex shapes. The vertical cross-sectional shape of the adjustment frame 330 is a "√" shape. The partial cross-sectional shape of the connection part between the adjustment frame 330 and the lower suction cup fixture 410 and the electric cylinder 420 is a "丨" shape. A blocking ring 500 is fixedly connected to the bottom of the mounting plate 200. The annular slide rail 310 is arranged inside the blocking ring 500.
[0035] In this embodiment, when the staff needs to adjust the processing position of the locking mechanism 400 together with the optical lens, the staff only needs to correspondingly control the servo motor 323 to rotate a corresponding angle. The servo motor 323 drives the spur gear 322 to rotate a corresponding angle. The spur gear 322 drives the internal gear ring 321 to rotate a corresponding angle. The internal gear ring 321 drives the adjustment frame 330 to rotate a corresponding angle along the annular slide rail 310. The adjustment frame 330 drives the locking mechanism 400 together with the optical lens to rotate a corresponding angle around the mounting plate 200 until the optical lens is rotated and adjusted to the corresponding position. Since the connection part between the internal gear ring 321 and the annular slide rail 310 faces away from the optical lens and is arranged between the mounting plate 200 and the blocking ring 500, this can separate impurities such as debris and cutting fluid generated during processing from the connection part between the internal gear ring 321 and the annular slide rail 310, enabling the electric adjustment component 320 to operate in a clean environment to ensure that the processing position of the optical lens can be normally adjusted.
[0036] As Figure 2 and Figure 4As shown, the locking mechanism 400 includes a lower suction cup clamp 410 and an electric cylinder 420. The lower suction cup clamp 410 and the electric cylinder 420 are respectively fixedly connected to opposite ends of the adjusting frame 330. An upper suction cup clamp 430, located directly above the lower suction cup clamp 410, is fixedly connected to the end of the output shaft of the electric cylinder 420. A rubber bellows 440 is fixedly connected between the upper suction cup clamp 430 and the electric cylinder 420. The rubber bellows 440 is sleeved on the outside of the output shaft of the electric cylinder 420. It should be noted that the opposite ends of the lower suction cup clamp 410 and the upper suction cup clamp 430 can be detachably connected to mounting brackets. The lower mounting bracket is fixedly connected to the adjusting frame 330. Together, the upper mounting bracket is detachably connected to the end of the output shaft of the electric cylinder 420 and the top of the rubber bellows 440. The lower suction cup clamp 410 and the upper suction cup clamp 430 need to be selected according to whether the optical lens needs to rotate during the processing, so as to meet the processing requirements of the optical lens under different conditions. The ratio of the distance between the lower suction cup clamp 410 and the upper suction cup clamp 430, the maximum extension length of the output shaft of the electric cylinder 420 and the maximum extension length of the rubber bellows 440 is 1:2:3. The minimum inner diameter of the rubber bellows 440 is greater than the diameter of the output shaft of the electric cylinder 420.
[0037] In this embodiment, when the operator needs to clamp and fix the optical lens, the operator only needs to place the optical lens on the top of the lower suction cup clamp 410 and actively correct the position of the optical lens. Then, the operator manually controls the electric cylinder 420 to retract, and the electric cylinder 420 drives the upper suction cup clamp 430 to move down until the lower suction cup clamp 410 and the upper suction cup clamp 430 cooperate to clamp and fix the optical lens. Since the rubber bellows 440, together with the cylinder wall of the electric cylinder 420 and the upper suction cup clamp 430, can form a flexible movable sealed space that covers the output shaft of the electric cylinder 420, this can separate the chips, cutting fluid and other impurities generated during processing from the output shaft of the electric cylinder 420. This can ensure that the output shaft of the electric cylinder 420 operates in a clean environment, so as to ensure that the optical lens can be locked or unlocked normally.
[0038] It should be noted that the internal gear ring 321, spur gear 322, servo motor 323, lower suction cup clamp 410, electric cylinder 420, upper suction cup clamp 430, and rubber bellows 440 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the servo motor 323 and electric cylinder 420 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
