Description

Technical Field

[0001] The utility model belongs to the technical field of glasses processing equipment, and in particular relates to a glasses frame hinge installation device. Background Art

[0002] The structure of glasses includes frames and lenses. From the perspective of materials, frame glasses can be divided into plate frames, titanium frames, metal alloy frames, etc. The frames include frames and legs. The frames and legs are usually connected by hinges to achieve folding and opening of the legs.

[0003] A hinge machine is a device that embeds hinges at both ends of a plastic eyeglass frame. Traditional eyeglass frame hinges require the eyeglass frame to be positioned on a mold when being fixed, so as to ensure the accuracy of the hinge installation position. Most existing eyeglass frames are first fixed on a mold with a matching lens, and then the eyeglass frame is placed on the lens for positioning. Since the eyeglass frame will come into contact with the lens during loading and unloading, the lens will be worn out due to multiple loading and unloading, resulting in a lower degree of precision fit between the eyeglass frame and the lens, and then the eyeglass frame will shake on the outside of the lens, causing the positioning accuracy to gradually decrease.

[0004] Therefore, a hinge installation device for a glasses frame is proposed. Utility Model Content

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The utility model provides a hinge installation device for eyeglass frames, such as Figure 1-5As shown, it includes a glasses frame positioning mold seat 1, a moving groove 2 is opened on the top of the glasses frame positioning mold seat 1, and there are ten moving grooves 2 in total, and the ten moving grooves 2 are symmetrically opened on the top of the glasses frame positioning mold seat 1, and a moving platform 3 is slidably connected inside the moving groove 2, and a threaded hole 4 is opened at the central position of the top of the moving platform 3, and a threaded rod 5 is connected to the inside of the threaded hole 4 through a threaded engagement, and a glasses frame positioning column 6 is welded to the top of the threaded rod 5. The glasses frame positioning column 6 is made of stainless steel, and a round knob 7 is welded at the central position of the top of the glasses frame positioning column 6, and an anti-slip groove is opened on one side of the outer wall of the round knob 7, and a conical head 8 is welded to the bottom end of the threaded rod 5, and a through groove 9 is opened on one side of the outer wall of the moving platform 3, and an extrusion block 10 is arranged inside the through groove 9, and an outer wall of one side of the extrusion block 10 A slider 11 is integrally formed on the upper part, and a slide groove 12 is opened on the inner wall of one side of the through groove 9 near the outer side of the slider 11. The slider 11 is located inside the slide groove 12, and the slider 11 and the slide groove 12 are slidably connected. A spring 13 is arranged between the inner wall of one side of the slide groove 12 and the outer wall of one side of the slider 11. A frustum 14 is integrally formed on the outer wall of one side of the extrusion block 10 adjacent to the slider 11. A fixing plate 15 is fixedly connected to the top of the eyeglass frame positioning mold seat 1 near the side position of the moving groove 2 by bolts. There are four fixing plates 15 in total, and the four fixing plates 15 are symmetrically arranged on the top of the eyeglass frame positioning mold seat 1. An electric push rod 16 is fixedly connected to the central position of the outer wall of one side of the fixing plate 15 by bolts, and the electric push rod 16 is fixedly connected to the top block 17 through the output end of one side thereof.

[0025] It should be noted that, when positioning the eyeglass frame, most existing nail hinge machines use matching lenses to first fix them on a mold, and then put the eyeglass frame on the lens for positioning. Since the eyeglass frame will be in contact with the lens during loading and unloading, the lens will be worn due to multiple loading and unloading, resulting in a lower precision fit between the eyeglass frame and the lens, and then the eyeglass frame will shake on the outside of the lens, causing the positioning accuracy to gradually decrease. The present embodiment replaces the traditional lens positioning method with an eyeglass frame positioning column 6. On the one hand, it effectively avoids the wear of the eyeglass frame positioning column 6 during loading and unloading of the eyeglass frame, ensures the accuracy of positioning after subsequent loading of the eyeglass frame, and then ensures the accuracy of the hinge installation on the eyeglass frame by the nail hinge machine. On the other hand, the movable characteristics of the eyeglass frame positioning column 6 can be utilized to adaptively adjust according to the shapes of different eyeglass frames, thereby facilitating the hinge installation requirements for eyeglass frames of different shapes.

[0026] Specifically, in the present embodiment, the present scheme mainly comprises a glasses frame positioning column 6. Before installing the glasses frame hinge, the glasses frame positioning mold seat 1 is fixedly mounted on the nail hinge machine, and the glasses frame to be hinged is positioned and placed on the glasses frame positioning mold seat 1. At this time, the moving platform 3 is moved by sliding the moving platform 3 in the moving groove 2, and the round knob 7 is pushed to realize the movement of the moving platform 3. When the glasses frame positioning column 6 is attached to the inner side of the lens groove on the glasses frame, the round knob 7 is rotated, and the glasses frame positioning column 6 and the threaded rod 5 at the bottom of the round knob 7 rotate synchronously. The threaded rod 5 and the threaded hole 4 are screwed together through the threaded connection, and the bottom conical head 8 of the threaded rod 5 rotates synchronously. And move downward, when the conical head 8 moves downward, the conical head 8 contacts the frustum 14, and through the sliding block 11 in the slide groove 12, the conical head 8 moves downward to extrude the frustum 14, and the extrusion block 10 pushes out of the through groove 9, and one end of the extrusion block 10 is squeezed on the inner wall of the moving groove 2, so as to fix the position of the moving platform 3 and the eyeglass frame positioning column 6. The eyeglass frame positioning column 6 is moved to fit the lens groove on the eyeglass frame, and can be adaptively adjusted according to the shape of the eyeglass frame. The eyeglass frame positioning column 6 is used to reduce the wear of the eyeglass frame during loading and unloading, thereby ensuring the accuracy of positioning after the subsequent eyeglass frame loading, thereby ensuring the accuracy of the hinge installation on the eyeglass frame by the nail hinge machine.

[0027] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the cross sections of the movable groove 2 and the movable platform 3 are both convex structures, and a cavity is provided inside the eyeglass frame positioning mold seat 1 near the position directly below the movable groove 2 .

[0028] In this embodiment, the "convex" shaped moving groove 2 and moving platform 3 can ensure the stability of the moving platform 3 in the moving groove 2, and the cavity setting can be used to provide space for the lifting and lowering movement of the extrusion block 10 and the horizontal movement of the cone 14.

[0029] In a further preferred embodiment of the present invention, Figure 3-4 As shown, the outer wall of one side of the conical head 8 and the frustum 14 fits closely together.

[0030] In this embodiment, when the conical head 8 moves downward, the conical head 8 moves downward to extrude the conical table 14 by utilizing the matching inclined surfaces on the conical head 8 and the conical table 14. By sliding the slider 11 in the slide groove 12, the extrusion block 10 is pushed out of the through groove 9, and one end of the extrusion block 10 is pressed on the inner wall of the moving groove 2, thereby fixing the position of the moving platform 3 and the eyeglass frame positioning column 6.
