Description

Technical Field

[0001] This utility model relates to the technical field of eyeglass frame reshaping devices, specifically to a flexible adjustable multi-station eyeglass frame reshaping device. Background Technology

[0002] MIM (Metal Injection Molding) is a novel near-net-shape forming technology for metal parts, integrating plastic molding processes, polymer chemistry, powder metallurgy, and metal materials science. It has unparalleled advantages over conventional powder metallurgy, machining, and precision casting methods, and is widely used in the eyeglass frame manufacturing industry. By adding metal or ceramic powder to plastic, and then performing multiple processes such as MIM injection and sintering, eyeglass frames with high strength and good wear resistance are obtained. However, the material is prone to deformation during the sintering process, requiring subsequent shaping to ensure the quality of the final eyeglass frame. Shaping requires the use of a multi-station integrated shaping device to grind and process the eyeglass frame to ensure that the dimensions of the eyeglass frame meet the requirements and achieve the appearance requirements after assembly.

[0003] Chinese patent CN215470133U discloses a flexible grinding and polishing device for eyeglass frames. It is equipped with a universal joint. By loosening the bolts on the fixing plate, the mounting plate can be adjusted left and right via a hinge, thereby adjusting the angle of the grinding disc. The first rotating shaft inside the grinding disc causes the universal joint to swing accordingly, so that the bottom of the grinding disc can grind both sides of the eyeglass frame, avoiding the situation where the grinding disc cannot grind both sides of the eyeglass frame, and improving the grinding effect.

[0004] The existing technical solutions mentioned above have the following drawbacks: there is a lack of a monitoring structure for the size of the eyeglass frame during the polishing process. Since the size of the eyeglass frame is small, if there is over-polishing or under-polishing, the size of the eyeglass frame will deviate, resulting in the eyeglass frame failing to meet the quality standards.

[0005] To address this, a multi-position reshaping device for eyeglass frames with flexible adjustment is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a flexible adjustable multi-position eyeglass frame shaping device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A flexible adjustable multi-station eyeglass frame shaping device includes an operating table. Support legs are fixedly installed at the four corners of the bottom surface of the operating table. A lifting assembly is fixedly installed on the top surface of the operating table. A horizontally arranged electric guide rail is fixedly installed on the telescopic end surface of the lifting assembly. A mounting box is fixedly installed on the moving part of the electric guide rail. Two opposing clamping blocks are provided on the bottom surface of the mounting box.

A second electrically controlled distance adjustment mechanism for driving the fixing components to clamp the eyeglass frame is provided on the surface of the rotating disk.

[0009] Furthermore, the lifting assembly includes an electric telescopic rod and a driven telescopic rod, which are respectively fixedly installed on the left and right sides of the top surface of the operating platform, and the electric guide rail is fixedly installed on the telescopic end surfaces of the electric telescopic rod and the driven telescopic rod.

[0010] Furthermore, the first electrically controlled adjusting mechanism includes a first slide groove and a first motor. There are two first slide grooves, which are symmetrically opened on the bottom surface of the mounting box. The first motor is fixedly installed on the surface of the mounting box. The output end of the first motor is fixedly connected to a first double-ended threaded rod. The first double-ended threaded rod is rotatably arranged through the inner wall surface of the two first slide grooves. A moving block is slidably installed on the inner wall surface of the first slide groove. The two moving blocks are symmetrically threaded onto the surface of the first double-ended threaded rod. The clamping block is fixedly installed on the bottom surface of the moving block.

[0011] Furthermore, the anti-reverse drive assembly includes a part cavity, which is located inside the operating table. A worm gear is rotatably mounted on the inner wall surface of the part cavity. The worm gear is rotatably disposed through the side of the operating table. A worm wheel is meshed on the surface of the worm gear. A rotating shaft is fixedly mounted on the surface of the worm wheel. The rotating shaft is rotatably mounted on the bottom surface of the inner wall of the part cavity and rotatably disposed through the top surface of the operating table. A rotating disk is fixedly mounted on the top surface of the rotating shaft. A knob is fixedly mounted on the surface of one end of the worm gear that passes through the side of the operating table.

[0012] Furthermore, the top surface of the operating table is provided with an installation groove, the rotating disk is rotatably mounted against the inner wall surface of the installation groove, and the rotating shaft is rotatably mounted through the bottom surface of the inner wall of the installation groove.

[0013] Furthermore, the fixing component includes a first extrusion block and a second extrusion plate, the first extrusion block and the second extrusion plate are arranged opposite each other, the first extrusion block and the second extrusion plate are respectively fixedly installed on the moving part surface of the second electrically controlled adjusting mechanism, a support block is fixedly installed on the side surface of the second extrusion plate near the first extrusion block, a slot is opened on the surface of the first extrusion block, and the support block is slidably arranged to fit against the inner wall surface of the slot.

[0014] The beneficial effects of this utility model are as follows:

[0015] The first electronically controlled distance adjustment mechanism controls the movement of two clamping blocks, ensuring that the distance between the two sandpapers is the same as the target size of the part of the eyeglass frame to be polished. Then, the electric guide rail drives the clamping blocks and sandpaper to move left and right, thus polishing the surface of the eyeglass frame. This avoids over-polishing or insufficient polishing by the clamping blocks, effectively ensuring the dimensional accuracy of the polished part of the eyeglass frame and guaranteeing the shaping effect. The anti-reverse drive component drives the rotating disk to rotate, adjusting the angle of the eyeglass frame, which facilitates polishing different parts of the eyeglass frame.

[0026] like Figures 1 to 4As shown, a flexible adjustable eyeglass frame multi-station shaping device includes an operating table 1. Support legs 2 are fixedly installed at the four corners of the bottom surface of the operating table 1. A lifting assembly 3 is fixedly installed on the top surface of the operating table 1. A horizontally arranged electric guide rail 4 is fixedly installed on the telescopic end surface of the lifting assembly 3. An installation box 13 is fixedly installed on the moving part surface of the electric guide rail 4. Two front-to-back clamping blocks 6 are provided on the bottom surface of the installation box 13. A first electrically controlled distance adjustment mechanism 5 for adjusting the distance between the two clamping blocks 6 is provided on the surface of the installation box 13. Sandpaper 7 is fixedly installed on the opposite surfaces of the two clamping blocks 6. A rotating disk 8 is rotatably installed on the top surface of the operating table 1. A reverse rotation drive assembly 9 for driving the rotating disk 8 to rotate is provided on the surface of the operating table 1. A fixing assembly 12 is provided on the top surface of the rotating disk 8. There are two fixing assemblies 12, which are arranged left and right opposite each other. A second electrically controlled distance adjustment mechanism 11 for driving the fixing assembly 12 to clamp the eyeglass frame is provided on the surface of the rotating disk 8.

[0027] More specifically, the eyeglass frame to be shaped and polished is placed on the surface of the fixing component 12. Driven by the second electronically controlled adjustment mechanism 11, the fixing component 12 clamps and fixes the eyeglass frame. The telescopic end of the lifting component 3 moves to drive the electric guide rail 4, the first electronically controlled adjustment mechanism 5, and the clamping block 6 to rise and fall, so that the two clamping blocks 6 set in front and behind are respectively located on the front and back sides of the eyeglass frame. The first electronically controlled adjustment mechanism 5 controls the movement of the two clamping blocks 6 so that the distance between the two sandpapers 7 is the same as the target size of the part of the eyeglass frame to be polished. Then, the electric guide rail 4 drives the clamping blocks 6 and the sandpaper 7 to move left and right to polish the surface of the eyeglass frame, avoiding over-polishing or insufficient polishing of the clamping blocks 6, effectively ensuring the dimensional accuracy of the polished part of the eyeglass frame and ensuring the shaping effect. The anti-reverse drive component 9 drives the rotating disk 8 to rotate, adjusting the angle of the eyeglass frame, which facilitates polishing different parts of the eyeglass frame.

[0028] The lifting assembly 3 includes an electric telescopic rod 301 and a driven telescopic rod 302. The electric telescopic rod 301 and the driven telescopic rod 302 are respectively fixedly installed on the left and right sides of the top surface of the operating table 1. The electric guide rail 4 is fixedly installed on the telescopic end surfaces of the electric telescopic rod 301 and the driven telescopic rod 302.

[0029] Specifically, the electric telescopic rod 301 actively extends and retracts, driving the electric guide rail 4 to rise and fall. The driven telescopic rod 302, while assisting in supporting the electric guide rail 4, avoids asynchronous rising and falling of the left and right ends of the electric guide rail 4 through the passive extension and retraction of its own telescopic end. The rising and falling of the electric guide rail 4 drives the mounting box 13, the first electrically controlled distance adjustment mechanism 5, the clamping block 6, the sandpaper 7 and other structures to rise and fall synchronously.

[0030] The first electrically controlled adjusting mechanism 5 includes a first slide groove 501 and a first motor 502. There are two first slide grooves 501, which are symmetrically opened on the bottom surface of the mounting box 13. The first motor 502 is fixedly installed on the surface of the mounting box 13. The output end of the first motor 502 is fixedly connected to a first double-ended threaded rod 503. The first double-ended threaded rod 503 is rotatably set through the inner wall surface of the two first slide grooves 501. A moving block 504 is slidably installed on the inner wall surface of the first slide groove 501. The two moving blocks 504 are symmetrically threaded on the surface of the first double-ended threaded rod 503. A clamping block 6 is fixedly installed on the bottom surface of the moving block 504.

[0031] Specifically, the output end of the first motor 502 drives the first double-ended threaded rod 503 to rotate, causing two moving blocks 504 with symmetrical threads installed on the surface of the first double-ended threaded rod 503 and slidably installed on the inner wall surface of the first slide groove 501 to move synchronously towards or away from each other. By controlling the operation of the first motor 502, the distance between the moving blocks 504 is precisely controlled and adjusted, thereby adjusting the distance between the two clamping blocks 6, and finally adjusting the distance between the two sandpapers 7 to the target value of the grinding position, so as to achieve precise grinding and shaping of the eyeglass frame.

[0032] The anti-reverse drive assembly 9 includes a part cavity 901, which is located inside the operating table 1. A worm gear 902 is rotatably mounted on the inner wall surface of the part cavity 901. The worm gear 902 is rotatably mounted through the side of the operating table 1. A worm wheel 903 is meshed on the surface of the worm gear 902. A rotating shaft 904 is fixedly mounted on the surface of the worm wheel 903. The rotating shaft 904 is rotatably mounted on the bottom surface of the inner wall of the part cavity 901 and rotatably mounted through the top surface of the operating table 1. A rotating disk 8 is fixedly mounted on the top surface of the rotating shaft 904. A knob 905 is fixedly mounted on the surface of one end of the worm gear 902 that passes through the side of the operating table 1.

[0033] Specifically, rotating the knob 905 drives the worm 902 to rotate, causing the worm wheel 903 meshing on the surface of the worm 902 to rotate. This ultimately drives the rotating shaft 904, which is fixedly mounted on the surface of the worm wheel 903, to rotate. This, in turn, drives the rotating disk 8, which is fixedly mounted on the top surface of the rotating shaft 904, to rotate. By utilizing the unidirectional transmission characteristic of the meshing worm wheel 903 and worm 902, reliable positioning of the rotation angle of the rotating disk 8 is achieved, effectively preventing the rotating disk 8 from rotating erroneously during the grinding process. This ensures smooth grinding and guarantees grinding accuracy.

[0034] The top surface of the control panel 1 is provided with an installation groove 10, the rotating disk 8 is fitted to the inner wall surface of the installation groove 10 and rotates, and the rotating shaft 904 passes through the bottom surface of the inner wall of the installation groove 10 and rotates.

[0035] Specifically, the mounting groove 10 is used to accommodate and protect the rotating disk 8, so that when the rotating shaft 904 drives the rotating disk 8 to rotate, the rotating disk 8 is more stable and reliable, avoiding the rotating disk 8 from tilting or being damaged under external force, and extending the service life of the rotating disk 8.

[0036] The fixing component 12 includes a first pressing block 121 and a second pressing plate 122. The first pressing block 121 and the second pressing plate 122 are arranged opposite to each other. The first pressing block 121 and the second pressing plate 122 are respectively fixedly installed on the moving part surface of the second electrically controlled adjusting mechanism 11. A support block 123 is fixedly installed on the side surface of the second pressing plate 122 near the first pressing block 121. A slot 124 is opened on the surface of the first pressing block 121. The support block 123 is slidably arranged to fit against the inner wall surface of the slot 124.

[0037] Specifically, the structural principle of the second electronically controlled adjustment mechanism 11 is the same as that of the first electronically controlled adjustment mechanism 5. When the two front-to-back moving parts of the second electronically controlled adjustment mechanism 11 move synchronously towards or away from each other, they drive the front-to-back first pressing block 121 and the second pressing plate 122 to move synchronously towards or away from each other. When it is necessary to clamp and fix the eyeglass frame, the first pressing block 121 and the second pressing plate 122 move closer to each other, and the eyeglass frame is placed on the top surface of the support block 123. As the first pressing block 121 and the second pressing plate 122 move closer to each other, the support block 123 slides into the slot 124. The first pressing block 121 and the second pressing plate 122 cooperate to press and fix the eyeglass frame from the front and back sides. The support block 123 supports the eyeglass frame from the bottom, effectively ensuring the stability of the eyeglass frame during the grinding and shaping process.

[0038] In summary: The first electronically controlled distance adjustment mechanism 5 controls the movement of the two clamping blocks 6, ensuring that the distance between the two sandpapers 7 is the same as the target size of the part of the eyeglass frame to be polished. Then, the electric guide rail 4 drives the clamping blocks 6 and sandpapers 7 to move left and right, thus polishing the surface of the eyeglass frame. This avoids over-polishing or under-polishing of the clamping blocks 6, effectively ensuring the dimensional accuracy of the polished part of the eyeglass frame and guaranteeing the shaping effect. The anti-reverse drive component 9 drives the rotating disk 8 to rotate, adjusting the angle of the eyeglass frame and facilitating polishing of different parts of the eyeglass frame.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
