Abstract
Description
A measuring device for optical lens processing Technical Field
[0001] This utility model relates to the field of optical lens measurement technology, and in particular to a measuring device for optical lens processing. Background Technology
[0002] Optical lenses are the core components of precision optical systems, and their manufacturing quality directly affects imaging performance. During lens manufacturing, high-precision measurement of key dimensions such as lens thickness and width is crucial for ensuring processing accuracy and assembly consistency. Traditional measuring devices are typically based on calipers or micrometers, reading dimensional values by measuring the relative displacement between a stop and a moving probe. These devices are widely used on lens production lines for rapid inspection of single or small batches of lenses.
[0003] However, existing optical lens measuring devices typically only have a single measuring structure, consisting of a fixed pair of measuring reference surfaces and a movable measuring point. Due to the significant differences in optical lens dimensions (e.g., small-diameter lenses are thin, while large-diameter lenses are thick or wide), a single measuring structure cannot simultaneously meet the measurement needs of lenses of different sizes. When measuring small, thin lenses, insufficient height of the measuring stop or limited travel of the movable probe often leads to operational inconvenience; while when measuring the thickness or width of large lenses, interference from the reference surface structure may prevent accurate contact with the measured surface. This forces operators to frequently change specialized measuring tools or repeatedly adjust the device, not only reducing inspection efficiency and increasing operational complexity but also potentially introducing human error due to multiple clamping operations, making it difficult to meet the demands of efficient, high-precision processing lines. Summary of the Invention
[0004] This invention provides a measuring device for optical lens processing that can adapt to lenses of different sizes and has multiple measurement modes.
[0005] The technical solution adopted by this utility model is as follows: a measuring device for optical lens processing, including a measuring ruler body, a fixed stop block integrally connected to one end of the measuring ruler body, a measuring slide sleeve and a fixed slide sleeve slidably sleeved on the measuring ruler body, a first measuring stop block fixedly connected to the bottom of the measuring slide sleeve near the fixed stop block, a guide rod slidably connected to the top of the measuring slide sleeve, a second measuring stop block fixedly connected to the end of the guide rod near the fixed stop block, the second measuring stop block and the measuring slide sleeve being connected by a spring sleeved on the outside of the guide rod, a lead screw passing through the fixed slide sleeve fixedly connected to the lower end of the measuring slide sleeve, and a knob threadedly connected to the lead screw at the lower end of the fixed slide sleeve.
[0006] As a further improvement of this utility model, the main surface of the measuring ruler is provided with a scale bar and the starting end of the scale bar is located at the fixed stop.
[0007] As a further improvement of this utility model, the fixed sliding sleeve is provided with an elastic locking block located at the top of the measuring ruler body, and the top of the fixed sliding sleeve is provided with a fastening bolt and the bottom end of the fastening bolt abuts against the top of the elastic locking block.
[0008] As a further improvement of this utility model, the fixed sliding sleeve is provided with a guide block that passes through the elastic locking block.
[0009] As a further improvement of this utility model, the lower end of the fixed sliding sleeve is provided with a groove, the knob is located in the groove and the lead screw passes through the groove.
[0010] As a further improvement of this utility model, the fixed stop block, which is higher than the main body of the measuring ruler, cooperates with the second measuring stop block to measure the thickness of a small-sized optical lens; the fixed stop block, which is lower than the main body of the measuring ruler, cooperates with the first measuring stop block to measure the thickness and width of a large-sized optical lens.
[0011] The beneficial effects of this utility model are as follows: By integrating a high and low dual measurement reference surface of the fixed stop and two independent measurement mechanisms (the first measurement stop and the second measurement stop), this utility model effectively solves the technical bottleneck that a single measurement structure cannot adapt to lenses of different sizes. The high surface of the fixed stop and the second measurement stop form a dedicated measurement channel for thin lenses, while the low surface and the first measurement stop constitute a thickness / width measurement system for large lenses. This allows for the coverage of measurement needs for both small-sized thin lenses and large-sized lenses without the need to change tools. Attached Figure Description

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.
[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0019] This utility model provides a measuring device for optical lens processing as shown in Figures 1-3, including a measuring ruler body 1. A fixed stop block 2 is integrally connected to one end of the measuring ruler body 1. A measuring slide sleeve 3 and a fixed slide sleeve 4 are slidably sleeved on the measuring ruler body 1. A first measuring stop block 5 is fixedly connected to the bottom of the measuring slide sleeve 3 near the fixed stop block 2. A guide rod 6 is slidably connected to the top of the measuring slide sleeve 3. A second measuring stop block 7 is fixedly connected to the end of the guide rod 6 near the fixed stop block 2. The second measuring stop block 7 and the measuring slide sleeve 3 are connected by a spring 8 sleeved on the outside of the guide rod 6. A lead screw 9 is fixedly connected to the lower end of the measuring slide sleeve 3 and passes through the fixed slide sleeve 4. A knob 10 is threadedly connected to the lead screw 9 at the lower end of the fixed slide sleeve 4.
[0020] As shown in Figures 1 and 2, the surface of the measuring ruler body 1 in this utility model is provided with a scale bar, and the starting end of the scale bar is located at the fixed stop 2, which makes it convenient for the operator to directly read the measurement value.
[0021] As shown in Figure 3, the fixed sliding sleeve 4 of this utility model is provided with an elastic locking block 11 located at the top of the measuring ruler body 1. The top of the fixed sliding sleeve 4 is provided with a fastening bolt 12 and the bottom end of the fastening bolt 12 abuts against the top of the elastic locking block 11. The fixed sliding sleeve 4 is provided with a guide block 13 that passes through the elastic locking block 11. Through the cooperation of the elastic locking block 11 and the fastening bolt 12, the fixed sliding sleeve 4 can be easily fixed in a suitable position on the measuring ruler body 1.
[0022] As shown in Figures 1-3, the lower end of the fixed sliding sleeve 4 in this invention has a groove, the knob 10 is located in the groove and the lead screw 9 passes through the groove, making the operation of the knob 10 more convenient, and also avoiding external interference affecting the measurement during use.
[0023] As shown in Figures 1-3, in this utility model, the fixed stop 2, which is higher than the main body 1 of the measuring ruler, cooperates with the second measuring stop 7 to measure the thickness of a small optical lens; the fixed stop 2, which is lower than the main body 1 of the measuring ruler, cooperates with the first measuring stop 5 to measure the thickness and width of a large optical lens.
[0024] In actual measurement, for the thickness measurement of small-sized optical lenses, the small-sized optical lens is placed between the fixed stop 2 (the part above the measuring ruler body 1) and the second measuring stop 7. Due to the action of the spring 8, the second measuring stop 7 can adaptively conform to the surface of the small-sized optical lens, and the operator can directly read the thickness value of the small-sized optical lens by observing the scale bar.
[0025] For measuring the thickness and width of large-size optical lenses, the large-size optical lens is placed between the fixed stop 2 (below the measuring scale body 1) and the first measuring stop 5. Rotating the knob 10 causes the lead screw 9 to slide the measuring sleeve 3 on the measuring scale body 1, gradually bringing the first measuring stop 5 closer to the large-size optical lens until it is in contact with it. Similarly, the operator reads the thickness or width value of the large-size optical lens by observing the scale bar.
[0026] Working Principle: In practical implementation, this invention first loosens the fastening bolt 12 and adjusts the position of the fixed sliding sleeve 4 on the measuring ruler body 1 to accommodate the measurement needs of optical lenses of different sizes. After adjustment, the fastening bolt 12 is tightened to ensure the elastic locking block 11 fits tightly against the measuring ruler body 1, fixing the fixed sliding sleeve 4 in place. When measuring small-sized optical lenses, the fixed stop 2 (higher than the measuring ruler body 1) and the second measuring stop 7 are used to place the small-sized optical lens into the measurement area. The second measuring stop 7 automatically fits against the lens surface under the action of the spring 8, and the thickness value is then read from the scale bar on the measuring ruler body 1. When measuring large-sized optical lenses, the fixed stop 2 (lower than the measuring ruler body 1) and the first measuring stop 5 are used. The knob 10 is rotated, and the lead screw 9 drives the measuring sliding sleeve 3 to move, allowing the first measuring stop 5 to approach and fit against the large-sized optical lens. Finally, the thickness or width value on the scale bar is read. This measurement method can quickly and accurately complete the measurement of optical lenses of different sizes, improving measurement efficiency and accuracy, and meeting the high-efficiency production needs of optical lens processing lines.
