[0002] Precision measurement refers to the process of measuring the size, shape, position, physical quantity, and other parameters of an object with high precision and accuracy under certain conditions using specialized instruments, methods, and techniques. It is widely used in many fields such as manufacturing, aerospace, scientific research, and medicine, and is a key link in ensuring product quality and achieving technological innovation.

[0003] In terms of workpiece clamping, traditional devices mostly rely on manual adjustment of the position of clamping components, which is not only cumbersome to operate, but also makes it difficult to ensure the balance of clamping forces on both sides. When the clamping forces are inconsistent, the workpiece is prone to tilting or shifting, resulting in deviations in the measurement reference and directly affecting the reliability of the measurement results. At the same time, most clamping structures are fixed designs and can only be adapted to workpieces of specific sizes or shapes. When facing diverse measurement needs, it is necessary to frequently change clamping components, which is complicated and time-consuming, and significantly reduces work efficiency.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a precision measuring device that is easy to read.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a precision measuring device that is easy to read, which can solve the problems of cumbersome operation of manually adjusting the clamping parts and uneven clamping force on both sides in traditional devices.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides the following technical solution: a precision measuring device for easy reading includes a support plate, on which two slides are provided, a slide plate is slidably connected inside each slide, a fixing block is fixedly connected inside each slide, both ends of each fixing block are connected to the slide plate by springs, a clamping assembly is provided on the outside of each slide plate, four fixing plates are fixedly installed at the bottom of the support plate, a rotating rod is connected between each group of fixing plates, two gears are fixedly installed on the outside of each rotating rod, the two gears mesh with each other, a pull rope is wound around the outside of each rotating rod, and the top end of each pull rope is connected to the slide plate.

[0024] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0025] like Figures 1 to 5As shown, a precision measuring device for easy reading in one embodiment of the present invention includes a support plate 1, on which two slides 9 are provided. A slide plate 8 is slidably connected inside each slide 9. A fixing block 10 is fixedly connected inside each slide 9. Both ends of each fixing block 10 are connected to the slide plate 8 through springs 12. A clamping assembly is provided on the outside of each slide plate 8. Four fixing plates 19 are fixedly installed at the bottom of the support plate 1. A rotating rod 21 is connected between each group of fixing plates 19. Two gears 7 are fixedly installed on the outside of each rotating rod 21. The two gears 7 mesh with each other. A pull rope 11 is wound around the outside of each rotating rod 21. The top end of each pull rope 11 is connected to the slide plate 8.

[0026] Specifically, through the linkage of the rotating rod 21, gear 7, pull rope 11 and spring 12, the two sliding plates 8 on both sides can be driven to move synchronously to clamp and release the workpiece without manual adjustment, simplifying the operation process. The meshing of gear 7 ensures the consistency of movement of the two sliding plates 8 on both sides, and the elasticity of spring 12 makes the clamping more stable, preventing the workpiece from loosening, laying the foundation for accurate measurement.

[0027] The clamping assembly includes two slots 18 on the outside of the slide plate 8. Each slot 18 houses a connecting block 13, and each connecting block 13 is externally fixed with a clamping block 14 by bolts. Each clamping block 14 has anti-slip textures on its exterior. Specifically, the engagement of the slots 18 and connecting blocks 13 with bolts facilitates quick replacement of clamping blocks 14 of different specifications, adapting to workpieces of different shapes and sizes, thus improving the device's versatility. The anti-slip textures on the exterior of the clamping blocks 14 increase friction with the workpiece, preventing slippage during measurement and enhancing clamping stability.

[0028] Each slide rail 9 is equipped with an anti-friction pad 15, and each pull rope 11 is in contact with the anti-friction pad 15. Specifically, the anti-friction pad 15 can reduce frictional wear between the pull rope 11 and the slide rail 9, extend the service life of the pull rope 11, and ensure the smoothness of the pull rope 11 when pulling the slide plate 8, avoiding the slide plate 8 from getting stuck due to excessive frictional resistance, and ensuring the stability of the clamping and measurement process.

[0029] The support plate 1 is fixedly mounted with a slide rail 5, which is slidably connected to two slide plates 8. Limiting blocks 6 are fixedly connected to both ends of the slide rail 5. Specifically, the slide rail 5 guides the movement of the slide plates 8, further ensuring the straightness of the slide plates 8 and preventing deviation from affecting measurement accuracy; the limiting blocks 6 prevent the slide plates 8 from sliding off the slide rail 5, ensuring the safety of the device, and at the same time limiting the range of movement of the slide plates 8 to prevent excessive movement from damaging the components.

[0030] Four limiting plates 20 are fixedly connected to the bottom of the support plate 1, and each limiting plate 20 is connected to the rotating rod 21. Specifically, the limiting plates 20 limit and support the rotating rod 21, preventing axial displacement or wobbling of the rotating rod 21 during rotation, ensuring the stability of gear 7 meshing and the accuracy of rope 11 winding, ensuring the reliable operation of the transmission system, and thus maintaining the accuracy of clamping and measurement. A support base 2 is fixedly installed at the bottom of the support plate 1, and four support pads 4 are fixedly installed at the bottom of the support base 2. Specifically, the support base 2 provides a stable support foundation for the entire device, improving the overall structural stability of the device; the support pads 4 increase the friction with the placement surface, preventing the device from sliding during use, while reducing the impact of external vibrations on the device, ensuring the stability of the measurement environment.

[0031] A handle 3 is externally connected to the support base 2. One end of the handle 3 passes through the support base 2 and connects to one of the rotating rods 21. Specifically, the handle 3 provides a convenient operating component for rotating the rotating rod 21. By manually turning the handle 3, the rotating rod 21 can be easily driven to rotate, thereby realizing the movement of the slide plate 8 and the clamping of the workpiece, reducing the difficulty of operation, improving the ease of use, and enabling operators to quickly get started. A scale 16 is fixedly installed on the front of the support plate 1, and a scale rod 17 is fixedly connected to the front end of one of the slide plates 8. Specifically, the scale rod 17 moves synchronously with the slide plate 8. In conjunction with the scale 16, it can intuitively reflect the measured dimensions of the workpiece. The operator can directly read the data without additional alignment operations, reducing reading errors and improving reading efficiency and accuracy.

[0032] Working principle: When a workpiece needs to be placed, the rotating rod 21 is driven to rotate. Since the gears 7 on the outside of the two rotating rods 21 mesh with each other, they will drive the two rotating rods 21 to rotate synchronously in opposite directions. When the rotating rod 21 rotates, the pull rope 11 wrapped around it is tightened, which in turn pulls the slide plate 8 connected to the top of the pull rope 11 to slide in the slide rail 9, pulling the two slide plates 8 apart. At this time, the slide plate 8 will stretch the springs 12 at both ends of the fixing block 10, so that its external clamping components move away from each other with the slide plate 8, making it easier to place the workpiece. After the workpiece is placed, the drive on the rotating rod 21 is released. The stretched spring 12 will use its own elasticity to contract and generate elastic restoring force, pushing the slide plate 8 to slide in the opposite direction in the slide rail 9. At the same time, the pull rope 11 is pulled, so that the rotating rod 21 rotates in the opposite direction and returns to its original position. The two slide plates 8 move closer to each other, and their external clamping components move accordingly, thereby achieving the clamping of the workpiece.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
