Traditional sheet metal measurement methods, such as manual selection using measuring tools like rulers and offline measurement during production, present certain inconveniences during processing and use, mainly the following problems:

[0003] 1. Lack of automated material screening: Currently, the selection of boards mainly relies on manual experience and measuring tape, lacking intelligent measurement methods, resulting in low material selection efficiency and poor accuracy, making it difficult to meet the needs of high-precision processing;

[0004] 2. Lack of real-time dimensional monitoring capability: During the processing, it is impossible to dynamically detect the cutting state and dimensional changes of the sheet metal, making it difficult to correct processing errors in a timely manner and resulting in a high scrap rate;

[0005] 3. Large errors in manual measurement: Relying on traditional measuring tools, such as measuring tapes, is easily affected by human operation, resulting in poor measurement consistency and affecting the stability of processing quality;

[0006] 4. Lack of data management: Measurement data is not digitally recorded and analyzed, which makes it impossible to optimize subsequent processing techniques and hinders the development of intelligent manufacturing;

[0007] These shortcomings severely restrict the precision, efficiency, and intelligence level of machine tool processing, and there is an urgent need to introduce automated measurement and real-time monitoring technologies to improve processing quality. Utility Model Content

[0018] This invention employs a symmetrical dual-movement drive mechanism in conjunction with an electric slide rail and an electric cylinder to form an adaptive clamping system. This ensures the plate remains stable between the two clamping plates, maintaining tight clamping and facilitating accurate length readings. An integrated laser sensor, ultrasonic thickness gauge, and visual recognition module constitute a multimodal measurement system, enabling simultaneous high-precision detection of plate dimensions, thickness, and surface features. This solves the problem of large errors in manual measurement. A specially designed telescopic plate with laser-marked graduations provides redundant measurement channels, enhancing system reliability.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, such as Figure 1-3As shown, the specific design of the aforementioned key components is described below: A measuring mechanism for a machine tool includes a bottom platform 1. Two symmetrically arranged cavities 2 are formed above the bottom platform 1. Two symmetrically arranged moving drive mechanisms 3 are located within the two cavities 2. Two supports 4 are positioned above each moving drive mechanism 3. An electric slide rail 5 is shared above the two supports 4. Two movable seats 6 are slidably arranged above the electric slide rail 5. A second motor 7 is positioned above the movable seats 6. A vision recognition module 8 is positioned above the second motor 7. The vision recognition module 8 can be driven by the second motor 7 to perform... The self-rotating mechanism facilitates all-around observation of materials. A first electric cylinder 9 is installed on the side of each of the two movable seats 6 located on the same electric slide rail 5. A clamping plate 12 is installed on the output end of the first electric cylinder 9 via a connecting pipe 10. The first electric cylinders 9 of the two moving drive mechanisms 3 cooperate to form two mutually movable clamping plates 12, clamping the material between them. A laser sensor 11 is installed on the inner side of the clamping plate 12. A vertically positioned second electric cylinder 21 is installed slightly above the inner side of the clamping plate 12. An ultrasonic thickness sensor 22 is installed below the second electric cylinder 21. The moving drive mechanism 3 includes a first motor 301, a bearing 304, a threaded rod 302, and a slider 303. The first motor 301 is located at one end of the cavity 2, the bearing 304 is located at the end of the cavity 2 away from the first motor 301, the threaded rod 302 is located between the first motor 301 and the bearing 304, and the slider 303 is slidably mounted on the threaded rod 302. A bracket 4 is installed above the slider 303. An extension tube 16 is mounted on one side of the bottom platform 1 via a connecting post 15. A clamp 18 is mounted on the extension tube 16. Multiple through holes are provided through the extension tube 16 vertically. The clamp 18 is fixed in the through holes by a pin 19. An L-shaped plate 20 is mounted on the clamp 18, and a laser sensor 11 is mounted on the inner side of the L-shaped plate 20. A data box 23 is mounted on one side of the bracket 4. The data box 23 is electrically connected to the visual recognition module 8 and the laser sensor 11. A touch screen 24 is electrically connected above the data box 23.First, the structure is placed on the machine tool. The extended tube 16, connected by the connecting column 15, moves outwards and downwards to allow for measurement and screening outside the machine tool, performing preliminary screening. Based on the ranging results of the laser sensor 11, the position of the clamp 18 is adjusted. The clamp 18 is fixed by passing through the through-hole 17 with the insert pin 19. Then, the plates are placed one by one at the ends of the two L-shaped plates 20 for comparison. Only plates whose length meets the cutting requirements are retained; those that do not are discarded. After selecting the plates, the moving drive mechanism 3 is activated. In other words, the first motor 301 starts, driving the threaded rod 302 to rotate. The rotation of the threaded rod 302 drives the slider 303 to move. The movement of the slider 303 drives the bracket 4 to move. The movement of the bracket 4 drives the electric slide rail 5 to move. The electric slide rail 5 drives the upper moving seat 6 to move. The movement of the moving seat 6 drives the first electric cylinder 9 to move. Because the moving drive mechanism 3 is symmetrically arranged, there are two electric slide rails 5 symmetrically arranged above the two symmetrical electric slide rails 5. This configuration forms four movable seats 6, each with a first electric cylinder 9 on its side. The four first electric cylinders 9 are symmetrically distributed in pairs. The symmetrically distributed first electric cylinders 9 are connected to two clamping plates 12 via connecting pipes 10. The two clamping plates 12 can move relative to each other to clamp the sheet metal, ensuring there are no gaps between the clamping plates 12. This allows for precise measurement of the length of the clamping plates 12. Then, the ultrasonic thickness sensor 22 driven by the second electric cylinder 21 can detect the thickness of the sheet metal quickly, accurately, and conveniently. After measurement, the components above the moving drive mechanism 3 are moved to one end of the bottom platform 1, so as not to affect the machine tool's cutting of the sheet metal. When needed, the components above the moving drive mechanism 3 are driven over for measurement. The laser sensor 11 inside the clamping plate 12 performs effective measurement, and the data from the laser sensor 11 and the ultrasonic thickness sensor 22 is transmitted back to the data box 23. The touch screen 24 on the top of the data box 23 not only facilitates observation but also allows for corresponding operations, simplifying the operation process. This machine tool measuring mechanism achieves intelligent screening and high-precision measurement of sheet metal through modular design. The symmetrically arranged dual-movement drive mechanism 3, in conjunction with the electric slide rail system 5, can quickly adjust the spacing of the clamping plates 12 to achieve automatic clamping and positioning of the sheet metal. The integrated laser sensor 11 and ultrasonic thickness gauge constitute a multimodal measurement system, which can simultaneously detect the size and thickness of the sheet metal, improving efficiency by more than 5 times compared to manual measurement. The extended measurement is pre-screened through the adjustable L-shaped plate 20 to ensure that the materials meet the processing requirements. The intelligent terminal composed of the data box 23 and the touch screen 24 realizes the visualization management of measurement data and optimization of process parameters, effectively reducing the scrap rate. The overall design has the advantages of high measurement accuracy, convenient operation and space saving, and perfectly solves the problems of low measurement efficiency and large error in traditional sheet metal processing.

[0027] A supplementary light 26 is installed inside the bracket 4, and a material compartment 25 is installed outside the bracket 4. One of the clamping plates 12 has an inner groove 13 on its upper part, through which one end of a telescopic plate 14 is connected via a hinge. The telescopic plate 14 has laser-marked graduation lines. The other clamping plate 14 has the other end of the telescopic plate 14 fixed to its top with screws. When not in use, the two clamping plates 12 can be disconnected by removing the screws, facilitating maintenance and upkeep of other components. The clamping plates 12 have multiple perforations on both sides, which helps reduce their weight and ease of movement and control. The supplementary light 26 provides illumination in low-light conditions. The material compartment 25 can store various documents for easy access. Both clamping plates 12 are movable; moving one clamping plate 12 allows the telescopic plate 14 to be pulled. The length of the sheet material can be read by reading the scale data on the telescopic plate 14 between the two clamping plates 12, providing redundant measurement channels and enhancing system reliability. One end of the telescopic plate 14 is set in the inner groove 13, which provides storage space for the hinge, and the other end is set on top of the other clamping plate 12. The telescopic plate 14 has length values ​​on it, making it easy to observe the length of the sheet material. The outer material compartment 25 provides convenient document storage and retrieval space for the staff. The clamping plates 12 adopt a hollow design to reduce weight and reduce the load on the moving mechanism. The surface of the telescopic plate 14 is marked with laser scale lines to form a redundant measurement system. When the two clamping plates 12 move to clamp the sheet material, the length data can be read intuitively through the scale on the telescopic plate 14 at the same time, and cross-validated with the measurement results of the laser sensor 11, which greatly improves the reliability of the system. The inner groove 13 provides storage space for the hinge. These improvements enable the mechanism to maintain high-precision measurement while also being easy to operate, environmentally adaptable, and data reliable, perfectly solving the problems of messy tools, single data, and environmental limitations in traditional measurement, and improving overall work efficiency.
