Description

Technical Field

[0001] The utility model relates to the technical field of cold processing of glass lenses, and particularly relates to a glass lens edge rolling jig. Background Technique

[0002] Cold processing of glass lenses refers to a series of processing operations on glass at room temperature to obtain lenses with the required shape and optical properties.

[0003] Due to the molding method of glass lenses, there is precipitated glass on the outer edge of the product, and outer circle contour processing is required. However, the thickness is uneven and the shape is irregular, resulting in difficult cold processing. Laser processing takes a long time and the equipment cost is high. According to the current process, a grinding wheel is used for rolling the outer circle. The inner wall thickness of the mold is uneven and the shape is irregular, which easily leads to insufficient concentricity and roundness accuracy in processing, and the closing and installation of the mold are relatively cumbersome. Content of the Utility Model

[0006] (II) Technical Solutions

[0007] To achieve the above object, the utility model is realized through the following technical solutions:

[0008] A glass lens edge rolling jig includes a left base and a right base.

[0009] Preferably: a second chamber is opened inside the left bushing, a first chamber is opened inside the right bushing, and the materials of the left bushing and the right bushing are both bakelite, and the shapes are matched with the outer shapes of the lenses to be processed.

[0010] (III) Beneficial Effects

[0011] 1. By placing a glass lens between the left bushing and the right bushing, then connecting and fixing the left base and the right base to the processing equipment through the positioning spigot and fine-thread inside them.

[0019] In an embodiment of the present application, by providing a glass lens edge rolling fixture, it effectively solves the problems that when using a grinding wheel for outer circle rolling processing, the inner wall thickness of the mold is uneven, and the irregular shape easily leads to insufficient concentricity and roundness accuracy in processing. Moreover, the closing and installation of the mold are relatively cumbersome. By placing the glass lens between the left bushing and the right bushing, then, the left base and the right base are connected and fixed to the processing equipment through the positioning stop and fine thread inside them. When the left bushing and the right bushing need to be closed, the guiding plug will be inserted into the positioning hole to ensure that the left bushing and the right bushing can fit tightly. The interface between the left base and the left bushing is simple, can be reused, and has a low cost. The smooth internal design and the combined use of the guiding plug and the positioning hole can ensure the concentricity and roundness of the product.

[0020] Embodiment

[0021] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the technical solution in the embodiment of the present application effectively solves the technical problems that when using a grinding wheel for outer circle rolling processing, the inner wall thickness of the mold is uneven, the irregular shape easily leads to insufficient concentricity and roundness accuracy in processing, and the closing and installation of the mold are relatively cumbersome. The general idea is as follows:

[0022] In view of the problems existing in the prior art, the present utility model provides a glass lens edge rolling fixture, including a left base 11 and a right base 13. A left bushing 12 is fixedly installed at the side end of the left base 11, a right bushing 14 is fixedly installed at the side end of the right base 13, and at least two guiding plugs 15 are fixedly installed at the side end of the right base 13. The interiors of the left base 11 and the right base 13 are designed as cavities so that they can communicate with the left bushing 12 and the right bushing 14. When performing outer circle rolling processing on the glass lens, we place the glass lens between the left bushing 12 and the right bushing 14. Then, the left base 11 and the right base 13 are connected and fixed to the processing equipment through the positioning stop and fine thread inside them. At least two positioning holes 18 are provided at the side end of the left bushing 12.

[0023] A second chamber 17 is provided inside the left bushing 12, a first chamber 16 is provided inside the right bushing 14. The materials of the left bushing 12 and the right bushing 14 are both bakelite, and their shapes match the shape of the lens to be processed. One end of the left bushing 12 and the right bushing 14 matches the shape of the lens, which can better fix the lens during the processing and ensure the stable position of the lens during processing. At the same time, using a copper base can ensure the firmness and stability of the connection, while the bakelite bushing is relatively soft and can avoid scratching the optical surface of the lens during processing.

[0024] Working principle:

[0025] First step, the left base 11, left bushing 12, right base 13, and right bushing 14 are all made of copper material, and they together form an assembly with a hexagonal structure at the tail. Specifically, the interiors of the left base 11 and the right base 13 are designed as cavities, so that they can communicate with the left bushing 12 and the right bushing 14. When performing the outer circle rolling process on the glass lens, we will place the glass lens between the left bushing 12 and the right bushing 14. Then, the left base 11 and the right base 13 are connected and fixed to the processing equipment through the positioning stop and fine thread inside them. When the left bushing 12 and the right bushing 14 need to be closed, the guiding plug 15 will be inserted into the positioning hole 18 to ensure that the left bushing 12 and the right bushing 14 can fit tightly. If there is any deviation in the angle between the left bushing 12 and the right bushing 14 during the closing process, the guiding plug 15 will contact the surface of the left bushing 12, resulting in the guiding plug 15 not being aligned with the positioning hole 18, thus leaving a gap between the left bushing 12 and the right bushing 14. This design can remind the staff that there is a deviation in the docking angle between the left bushing 12 and the right bushing 14.

[0026] Since one end of the left bushing 12 and the right bushing 14 is shaped to match the outer shape of the lens, it can better fix the lens during the processing, ensuring the stable position of the lens during processing. At the same time, using a copper base can ensure the firmness and stability of the connection, while the bakelite bushing is relatively soft, which can avoid scratching the optical surface of the lens during processing. Through this carefully designed jig, we can effectively solve the problems of insufficient machining concentricity and roundness accuracy caused by uneven thickness and irregular shape of the product's precipitation edge. This jig not only improves the machining accuracy but also ensures the safety and stability of the lens during processing.

[0027] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
