Abstract
Description
Technical Field
[0001] This utility model relates to the field of gauge block calibration technology, and in particular to a gauge block calibration device that can automatically adjust optical interference fringes. Background Technology
[0002] In the field of precision metrology, gauge blocks serve as crucial reference tools for length measurement, and their accurate calibration is of paramount importance. Gauge block calibration devices are widely used in metrology laboratories, quality control departments of machinery manufacturing enterprises, and other settings to ensure the dimensional accuracy of gauge blocks, thereby guaranteeing the precision of dimensional measurements during the production process.
[0003] In existing gauge block calibration devices, the optical interference fringe correlation devices typically have a relatively fixed structure. They often employ a simple optical path design, where light emitted from a light source forms interference fringes after passing through fixed optical elements such as beam splitters. However, this traditional structure has significant shortcomings. Because it cannot automatically adjust the optical interference fringes, it cannot flexibly adjust the optical path parameters to obtain clear and stable interference fringes when dealing with gauge blocks of different sizes, due to differences in gauge block thickness and optical characteristics. This significantly reduces the testing accuracy, making it difficult to meet the requirements of high-precision gauge block calibration. Furthermore, when testing gauge blocks of different specifications, a considerable amount of time is required for manual device adjustment, severely impacting work efficiency. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a gauge block calibration device capable of automatically adjusting optical interference fringes. The device includes a main body 1, which serves as the foundational support structure for the entire device, bearing all other components. A bracket 3 is fixedly connected to the upper surface of the main body 1, primarily supporting and fixing the internal components. A guide rail 7 is fixedly connected inside the bracket 3, and a slider 4 is slidably connected to the outer wall of the guide rail 7. The guide rail 7 provides a precise guiding path for the slider 4, allowing it to move smoothly along the guide rail 7. This design effectively controls the movement direction and displacement accuracy of the slider 4, thereby achieving precise position adjustment of the components connected to the slider 4. The outer wall of the slider 4... A connecting block 6 is fixedly connected to one side of the support bracket 3. A laser lamp 5 is fixedly connected to the side of the connecting block 6 away from the slider 4. By sliding the slider 4 on the guide rail 7, the connecting block 6 and the laser lamp 5 can be adjusted in height, improving the flexibility and adaptability of the device. A limiting component is fixedly connected to the outer wall of the support bracket 3. The limiting component includes a limiting block 8. The outer wall of the limiting block 8 is fixedly connected to the outer wall of the support bracket 3, and the lower surface of the limiting block 8 is fixedly connected to the upper surface of the support plate 13. The function of the limiting block 8 is to limit the sliding range of the slider 4 and prevent the laser lamp 5 from colliding with the beam splitter 9 due to excessive movement. A support plate 13 is fixedly connected to the outer wall of the support bracket 3, and the beam splitter 9 is fixedly connected to the upper surface of the support plate 13. The support plate 13 provides support for the beam splitter 9. A stable mounting surface is provided to ensure that the beam splitter 9 will not shift or shake due to external factors during operation. The beam splitter 9 plays a key role in the device, splitting the light emitted by the light source and directing it towards the reference mirror 26 and the gauge block to form the optical path required for interference. A support rod 21 is fixedly connected to the upper surface of the main body 1 of the detection device. A slide rail 27 is fixedly connected to the upper surface of the support rod 21. A slider 22 is slidably connected to the inner wall of the slide rail 27. A connecting plate 24 is fixedly connected to the upper surface of the slider 22. A fixing plate 23 is fixedly connected to the inner wall of the connecting plate 24. A fixing rod 25 is rotatably connected inside the fixing plate 23. The reference mirror 26 is fixedly connected to the end of the fixing rod 25 away from the fixing plate 23. The support rod 21 is the upper slide rail 27 and related components. The system provides vertical support. The cooperation between the slide rail 27 and the slider 22 allows the reference mirror 26 to be adjusted horizontally to meet different optical path calibration and interference fringe adjustment requirements. By rotating the fixing rod 25, the angle of the reference mirror 26 can be finely adjusted to further optimize the quality of the optical path and interference fringes. Slide grooves 12 are provided on both sides of the outer wall of the bracket 3. The outer wall of the slider 4 is slidably connected inside the slide grooves 12. The cooperation between the slide grooves 12 and the slider 4 further enhances the stability and guidance of the slider 4's movement. A stage 11 is fixedly connected to the upper surface of the main body 1 of the detection device. The stage 11 can be used to place the gauge block to be tested, as well as related auxiliary tools and accessories. An operation panel 2 is fixedly connected to the upper surface of the main body 1 of the detection device.The operation panel 2 typically integrates various control buttons, a display screen, and other user interface elements, allowing operators to control and set various functions and parameters of the device.
[0024] Reference Figure 1 - Figure 3 A worktable 10 is fixedly connected to the upper surface of the main body 1 of the detection device, providing a stable support foundation for the components subsequently installed inside and above it. A guide rail 20 is fixedly connected inside the worktable 10, providing a precise and stable guide track for the sliding of the slider 17. Its high-precision design allows the slider 17 to move smoothly along a predetermined direction within the guide rail 20, effectively limiting any possible horizontal offset or wobbling of the slider 17. The slider 17 is slidably connected to the inner wall of the guide rail 20, enabling precise movement under the guidance of the guide rail 20. The precise displacement movement, achieved by the movement of slider 2 17, can drive the upper mounting block 18 and its connected components to adjust their position in the horizontal direction, adapting to the inspection requirements of gauge blocks of different sizes or performing different position operations on the gauge blocks during the inspection process. The mounting block 18 is fixedly connected to the outer wall of slider 2 17, and the mounting block 18 serves to support and connect the stabilizing wheel 19. The pressing block 14 is fixedly connected to the upper surface of the mounting block 18. Under the action of the spring 15, the pressing block 14 can apply a certain pressure inward, cooperating with the pressing plate 16 to clamp the gauge block from both sides. Its design position and shape can effectively adapt to gauge blocks of different shapes and sizes, ensuring that the gauge blocks maintain a stable position during the inspection process. A stabilizing wheel 19 is rotatably connected to the inner wall of the mounting block 18. As the slider 17 moves along the guide rail 20, the stabilizing wheel 19 rolls below the pressing block 14. The stabilizing wheel 19 supports and stabilizes the pressing block 14, preventing it from tilting or shifting under external force or its own weight. A spring 15 is fixedly connected to the inner side of the pressing block 14. The spring 15 is a key component providing clamping force. When the gauge block is placed... When the gauge block is pressed, the spring 15 will generate appropriate elastic deformation according to the size and shape of the gauge block, thereby adjusting the distance between the pressing block 14 and the pressing plate 16 so that they can fit tightly against the surface of the gauge block. It can also reduce the pressing force on the gauge block and prevent damage to the gauge block. The pressing plate 16 is fixedly connected to the end of the spring 15 away from the pressing block 14. The pressing plate 16 and the pressing block 14 work together to form a clamping structure for the gauge block. Under the elastic force of the spring 15, the pressing plate 16 can press tightly against the other side surface of the gauge block, and cooperate with the pressing block 14 to achieve stable clamping of the gauge block.
[0025] Working principle: First, the gauge block to be tested is placed on the worktable 10. At this time, the initial position of slider 17 within guide rail 20 can be initially adjusted according to the approximate size of the gauge block for subsequent clamping operations. After the gauge block is placed, under the action of guide rail 20, the pressing block 14 and pressing plate 16 will clamp the gauge block. Spring 15 will generate corresponding elastic deformation according to the actual size of the gauge block, ensuring that the gauge block is stably clamped without being damaged by excessive compression. The stabilizing wheel 19 in mounting block 18 ensures the stability of pressing block 14 during this process, preventing it from tilting or shifting. Next, the operator activates laser lamp 5 through the operation panel 2. The light emitted by laser lamp 5 is directed towards beam splitter 9. Beam splitter 9 splits the light into two beams, one beam is directed towards reference mirror 26, and the other beam is directed towards the gauge block. The light beam directed towards reference mirror 26 is reflected and returns along the original path. The light beam directed towards the gauge block is reflected on the surface of the gauge block and also returns to beam splitter 9. The returning light rays reconverge at beam splitter 9. Due to the optical path difference, optical interference fringes are formed. During the inspection process, if it is necessary to adjust the height of laser lamp 5 to optimize the interference fringes, the slider 4 can be controlled to slide on guide rail 7 via operation panel 2, thereby driving laser lamp 5 to adjust its height. At the same time, in order to further adjust the clarity and position of the interference fringes, the operator can adjust the horizontal position of reference mirror 26 by using the cooperation of slide rail 27 and slider 22 before work or during the inspection process, and finely adjust the angle of reference mirror 26 by rotating fixed rod 25. By continuously adjusting the position and angle of laser lamp 5 and reference mirror 26, the interference fringes can be optimized to enable accurate calibration of the gauge block. The operator can measure and analyze the parameters such as the size of the gauge block using the relevant functions on operation panel 2 or external equipment based on the characteristics and changes of the interference fringes, thereby determining whether the gauge block meets the accuracy requirements.
