Description

Lens trimming die

Technical Field

The utility model relates to a lens processing equipment technical field, concretely relates to lens deburring mould.

Background

The lens is a transparent material product with one or more curved surfaces, which is made of optical materials such as glass or resin. The thickness of the lens depends mainly on the refractive index and power of the lens. The near vision lens is thin in the center and thick in the periphery, while the far vision lens is the opposite. Generally, the higher the power, the thicker the lens; the higher the refractive index, the thinner the lens.

After the concave lens is milled and ground, the edge of the concave surface of the lens is not milled and ground sufficiently, and burrs are easily generated, so that the quality of the lens is affected.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned prior art not enough, provide a lens deburring mould, can carry out the deburring to concave lens edge and polish, improve the quality of lens to improve machining efficiency.

The utility model discloses a realize like this, a lens deburring mould, including the die body, the die body includes cambered surface and plane, be equipped with the boss on the plane of die body, the boss middle part is equipped with the erection column of last extension, be equipped with through-hole, screw hole and bell mouth in the erection column in proper order, the cambered surface is carried out the deburring and is polished concave lens edge when the die body rotates.

In some embodiments, the width of the plane is 330 mm.

In some embodiments, the bosses are as wide as the plane, and the bosses have a height of 10 mm.

In some embodiments, the radius of the arc is 220 mm.

In some embodiments, the sum of the depths of the through hole, the threaded hole, and the tapered hole is less than the height of the mounting post.

In some embodiments, the diameter of the through hole is greater than the diameter of the threaded hole.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: the die body that sets up includes cambered surface and plane, and the cambered surface is carried out the deburring and is polished to concave lens edge when the die body rotates to the realization is carried out the deburring and is polished to concave lens edge, improves the quality of lens, and improves machining efficiency, is equipped with through-hole, screw hole and bell mouth in proper order in the erection column of setting for the installation pivot, makes the die body can rotate automatically.

Drawings

In order to more clearly illustrate the technical solution of the present invention, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic structural view of a lens trimming mold according to an embodiment of the present invention.

Detailed Description

The foregoing and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the embodiments with reference to the accompanying drawings. The following description contains various specific details to aid in this understanding, but these details should be construed as merely exemplary. Moreover, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "top", "bottom", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.

As shown in fig. 1, the embodiment of the utility model provides a lens deburring mould, including die body 1, it is concrete, die body 1 adopts the hemisphere shape to set up, and die body 1 includes cambered surface 2 and plane 3, and wherein cambered surface 2's surface has the sand-plated layer, can carry out the deburring effectively to concave lens edge and polish. The die body 1 is provided with a boss 4 on the plane, the die body 1 and the boss 4 are integrally formed by cast iron, the middle part of the boss 4 is provided with an installation column 5 which extends upwards, and the installation column 5 is formed on the boss 4 through turning. Be equipped with through-hole 6 in the erection column 5 in proper order, screw hole 7 and bell mouth 8, when using, pass through-hole 6 and screw hole 7 with the pivot (the surface has the screw thread and the end is the toper) of lathe and assemble, and the end of pivot is installed in bell mouth 8, the pivot just can drive die body 1 and have rotated like this, it needs to point out that the direction of screwing of pivot and the installation of screw hole 8 is unanimous with the direction of rotation of pivot, rotate the in-process in the pivot like this and can not cause 1 slippage of die body to go out the pivot. When the mold body 1 rotates, the cambered surface 2 carries out trimming and grinding on the edge of the concave lens, and preferably, a sand coating layer is arranged on the surface of the cambered surface 2 to carry out trimming and grinding on the edge of the concave lens.

Preferably, the width of the plane 3 is 330 mm. The boss 4 is as wide as the plane 3, so that the die body 1 and the boss 4 are used as a whole, and the height of the boss 4 is 10 mm.

Preferably, the cambered surface 2 has a radius of 220mm, and is suitable for trimming and grinding the edge of a concave lens with the radius of less than 220 mm.

Preferably, the sum of the depths of the through hole 6, the threaded hole 7 and the tapered hole 8 is smaller than the height of the mounting column 5, so that the through hole 6, the threaded hole 7 and the tapered hole 8 are prevented from penetrating through the mounting column 5, and the structure is not stable.

Preferably, the diameter of the through hole 6 is larger than that of the threaded hole 7, so that the rotating shaft of the machine tool can be smoothly installed through the through hole 6 and the threaded hole 7.

The above description is only exemplary embodiments of the present invention, and should not be construed as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
