Description

Technical Field

[0001] This invention relates to the field of measuring device technology, and in particular to a non-contact, high-precision dimensional measuring device for magnesia-carbon bricks. Background Technology

[0002] Magnesia-carbon bricks are key refractory materials in high-temperature industrial applications. Their dimensional accuracy and surface quality directly affect the sealing performance and service life of the masonry. Especially in steelmaking converters and ladles, excessive dimensional deviations in the bricks can lead to leaks and safety hazards. Therefore, extremely high precision requirements are placed on the dimensional inspection of magnesia-carbon bricks. Currently, the dimensional measurement of magnesia-carbon bricks still mainly relies on traditional contact methods, which depend on manual measurement using tools such as calipers and micrometers. This method has significant drawbacks: First, contact measurement can easily scratch the surface of the brick, damaging the dense structure of the magnesia-carbon brick and affecting its high-temperature resistance. Second, manual operation is greatly affected by subjective factors, resulting in large measurements that are difficult to meet the requirements of high-precision production. Third, for mass-produced magnesia-carbon bricks, manual measurement is extremely inefficient, and the inspection of each brick is very time-consuming, severely restricting the production pace. Meanwhile, existing non-contact measuring equipment also has significant shortcomings: the fixing methods of some devices' measuring components are cumbersome, requiring the disassembly of multiple fasteners when replacing or maintaining the laser rangefinder, which is complex and prone to positioning deviations; industrial cameras used for appearance inspection are mostly rigidly fixed, making it difficult to dissipate the heat generated during long-term operation, which can easily lead to a decrease in image acquisition accuracy, and the disassembly and maintenance are inconvenient, increasing equipment downtime. In addition, the coordination between the measurement and inspection systems is poor, making it difficult to achieve simultaneous and efficient detection of dimensions and surface quality, and unable to meet the fast-paced demands of modern production lines. Therefore, it is necessary to design a non-contact high-precision dimensional measuring device for magnesia-carbon bricks to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a non-contact, high-precision dimensional measuring device for magnesia-carbon bricks to solve the above-mentioned problems.

[0004] The above-mentioned technical objective of this invention is achieved through the following technical solution: a non-contact high-precision dimensional measuring device for magnesia-carbon bricks, comprising: A measuring platform, which is equipped with a high-precision measuring mechanism and a detection and disassembly mechanism; The high-precision measuring mechanism includes a square base, a connecting base, an electric slider, and a laser rangefinder; The square base is fixedly installed around the measuring platform, the connecting seat is engaged with the square base, the electric slider is slidably installed on the connecting seat, and the laser rangefinder is fixedly installed on the electric slider.

[0005] A further configuration of the present invention is as follows: the detection and disassembly mechanism includes a main frame, a top frame, a hydraulic cylinder, a push plate, a hollow seat, an industrial camera, a first sealing plate, a second sealing plate, and a heat-conducting fixing plate. The main frame is fixedly installed on the measuring platform, the top frame is fixedly installed on the top of the main frame, the hydraulic cylinder is fixedly installed on the top of the top frame, the hydraulic rod of the hydraulic cylinder is fixedly connected to the push plate, the hollow seat is fixedly installed on the main frame, and a plurality of L-shaped holes are provided on the hollow seat. The first sealing plate and the second sealing plate are slidably and sealingly installed in the L-shaped holes, the L-shaped holes are filled with hydraulic oil, the heat-conducting fixing plate is fixedly connected to the second sealing plate, and the heat-conducting fixing plate abuts against the industrial camera.

[0006] A further embodiment of the present invention is that the detection and disassembly mechanism further includes a vertical plate, a connecting rod, and a baffle. The vertical plate is fixedly installed at the bottom of the push plate, the connecting rod is fixedly connected to the vertical plate, the bottom of the connecting rod is fixedly connected to the baffle, and the side of the baffle abuts against the connecting seat.

[0007] A further feature of the present invention is that a square hole is provided on the side of the connecting seat, the square seat is engaged with the square hole, and the side of the connecting seat is in contact with the measuring table.

[0008] A further feature of the present invention is that a groove is provided on the top of the connecting seat, and an electric slider is slidably installed in the groove.

[0009] A further provision of the present invention is that a magnesium-carbon brick is placed on top of the measuring platform.

[0010] A further configuration of the present invention is that the top of the industrial camera is in contact with the main frame.

[0011] A further feature of the present invention is that the number of the thermally conductive fixing plates is multiple, and the multiple thermally conductive fixing plates are arranged in a ring with equal spacing.

[0012] The beneficial effects of this invention are: This invention utilizes a high-precision measuring mechanism. A laser rangefinder slides along a connecting seat via an electric slider to perform non-contact scanning measurement of magnesia-carbon bricks. This avoids the scratch damage to the brick surface caused by traditional contact measurement, protecting the dense structure and high-temperature resistance of the magnesia-carbon bricks. At the same time, the symmetrically arranged laser rangefinders can calculate the dimensions through the reference distance difference, significantly reducing measurement errors and achieving accuracy far superior to manual measurement. This meets the requirements of high-precision production. The automated cooperation between the laser rangefinder and the electric slider significantly improves efficiency compared to manual measurement. Simultaneously, an industrial camera completes appearance inspection, achieving simultaneous detection of dimensions and surface quality, solving the problems of low efficiency and difficulty in adapting to mass production in traditional inspection methods. This invention utilizes a specially designed detection and disassembly mechanism. A hydraulic cylinder drives a push plate, and hydraulic oil within an L-shaped hole transmits power, allowing the heat-conducting fixing plates to quickly clamp or release the industrial camera without disassembling multiple fasteners. This simplifies camera maintenance. For laser rangefinders, the push plate moves the baffle up and down, quickly fixing or releasing the connector, facilitating the replacement and calibration of the ranging components. This avoids the complex operation and positioning errors associated with traditional fixing methods, reducing equipment downtime for maintenance. Multiple annularly distributed heat-conducting fixing plates effectively dissipate heat generated by the camera while fixing it, preventing overheating-induced image acquisition accuracy degradation and ensuring accurate appearance inspection. The collaborative design of the measurement and detection mechanisms further enhances the overall stability and reliability of the equipment. Attached Figure Description

[0021] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more unless otherwise explicitly specified.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] See Figures 1-6 This invention provides a non-contact, high-precision dimensional measuring device for magnesia-carbon bricks, comprising: Measuring table 1, which is equipped with a high-precision measuring mechanism and a testing and disassembly mechanism; The high-precision measuring mechanism includes a square base 2, a connecting base 3, an electric slider 4, and a laser rangefinder 5; Square base 2 is fixedly installed around the measuring platform 1, connecting base 3 is engaged with square base 2, electric slider 4 is slidably installed on connecting base 3, and laser rangefinder 5 is fixedly installed on electric slider 4.

[0027] With the above structure, the magnesia-carbon brick 6 is placed on top of the measuring platform 1. The laser rangefinder 5 and the electric slider 4 are started. The electric slider 4 drives the laser rangefinder 5 to move. During the movement, the two laser rangefinders 5 can measure the size of the magnesia-carbon brick 6. The measurement is obtained by subtracting the length of the magnesia-carbon brick 6 from the distance between the two laser rangefinders 5.

[0028] Specifically, the testing and disassembly mechanism includes a main frame 7, a top frame 8, a hydraulic cylinder 9, a push plate 10, a hollow seat 11, an industrial camera 12, a first sealing plate 13, a second sealing plate 14, and a heat-conducting fixing plate 16. The main frame 7 is fixedly installed on the measuring table 1, the top frame 8 is fixedly installed on the top of the main frame 7, the hydraulic cylinder 9 is fixedly installed on the top of the top frame 8, the hydraulic rod of the hydraulic cylinder 9 is fixedly connected to the push plate 10, the hollow seat 11 is fixedly installed on the main frame 7, and multiple L-shaped holes 15 are opened on the hollow seat 11. The first sealing plate 13 and the second sealing plate 14 are slidably sealed in the L-shaped holes 15, and the L-shaped holes 15 are filled with hydraulic oil. The heat-conducting fixing plate 16 is fixedly connected to the second sealing plate 14 and abuts against the industrial camera 12.

[0029] Through the above structure, the industrial camera 12 can record and process the magnesia-carbon brick 6 and transmit the data to the backend for comparison with the standard magnesia-carbon brick 6. Feedback processing can be performed when there are differences. This can effectively inspect the appearance of the magnesia-carbon brick 6. Placing the industrial camera 12 in the hollow seat 11 and activating the hydraulic cylinder 9 can cause the pusher plate 10 to move downwards. This allows the sealing plate 13 to move downwards. The sealing plate 13 pushes the hydraulic oil, which causes the sealing plate 14 to move the heat-conducting fixing plate 16. This allows multiple heat-conducting fixing plates 16 to quickly clamp and fix the industrial camera 12. When maintenance is required later, it is convenient to quickly remove the industrial camera 12 for maintenance. Moreover, the heat-conducting fixing plate 16 can effectively dissipate heat from the industrial camera 12, thus ensuring the working effect of the industrial camera 12.

[0030] Specifically, the testing and disassembly mechanism also includes a vertical plate 17, a connecting rod 18, and a baffle 19. The vertical plate 17 is fixedly installed at the bottom of the push plate 10, the connecting rod 18 is fixedly connected to the vertical plate 17, the bottom of the connecting rod 18 is fixedly connected to the baffle 19, and the side of the baffle 19 abuts against the connecting seat 3.

[0031] With the above structure, the connecting seat 3 is also snapped into the square seat 2. When the push plate 10 moves down, the vertical plate 17 can move down, which in turn allows the connecting rod 18 to drive the baffle 19 to move downward. The baffle 19 blocks the connecting seat 3, thus effectively limiting the position of the connecting seat 3. In the future, it is convenient to quickly remove the connecting seat 3 for maintenance.

[0032] Specifically, a square hole 21 is provided on the side of the connecting seat 3, and the square seat 2 is engaged with the square hole 21. The side of the connecting seat 3 is in contact with the measuring table 1, which facilitates the engagement of the connecting seat 3.

[0033] Specifically, the top of the connecting seat 3 is provided with a slide groove 20, and the electric slider 4 is slidably installed in the slide groove 20 to facilitate the movement of the electric slider 4 within the slide groove 20.

[0034] Specifically, a magnesia-carbon brick 6 is placed on top of the measuring table 1. The dimensions of the magnesia-carbon brick 6 are measured, and the appearance of the magnesia-carbon brick 6 is inspected.

[0035] Specifically, the top of the industrial camera 12 is in contact with the main frame 7, which can limit the position of the industrial camera 12.

[0036] Specifically, there are multiple heat-conducting fixing plates 16, and the multiple heat-conducting fixing plates 16 are arranged in a ring with equal spacing, which makes it convenient to clamp and fix the industrial camera 12, and also facilitates the rapid heat dissipation of the industrial camera 12.

[0037] Working principle: During the dimensional measurement stage, the magnesia-carbon brick 6 to be tested is placed on top of the measuring platform 1. The connecting seat 3 is positioned using the square bases 2 around the measuring platform. The connecting seat 3 is fixed to the square base 2 through the square holes 21 on its side, ensuring the initial position of the laser rangefinder 5 is stable. The electric slider 4 is activated, sliding along the groove 20 on the top of the connecting seat 3, driving the laser rangefinder 5 to move linearly. Since there are symmetrical laser rangefinders 5 around the measuring platform, two laser rangefinders in the same direction can simultaneously scan the corresponding sides of the magnesia-carbon brick. By calculating the difference between the reference distance between the two rangefinders and the distance to the brick surface measured by each rangefinder, the length, width, and other dimensional parameters of the magnesia-carbon brick can be accurately obtained. The entire process does not require contact with the brick, avoiding damage to the surface of the magnesia-carbon brick. During the appearance inspection and equipment fixing stage, the industrial camera 12 on the main frame 7 is responsible for capturing images of the magnesia-carbon brick surface and transmitting them to the backend for comparison with standard samples to identify defects such as cracks and dents. The installation and fixing of the industrial camera is completed through the inspection and disassembly mechanism: after the camera is placed in the hollow seat 11, the hydraulic cylinder 9 on the top frame 8 is activated, and its hydraulic rod pushes the push plate 10 down, causing the sealing plate 13 at the bottom of the push plate to squeeze the hydraulic oil in the L-shaped hole 15. The hydraulic oil transmits the pressure to the sealing plate 14, causing multiple annularly distributed heat-conducting fixing plates 16 to move synchronously towards the center, tightly clamping the industrial camera 12. This ensures the stability of the shooting and prevents the camera from overheating and affecting accuracy due to prolonged operation through the heat dissipation effect of the heat-conducting fixing plates. When maintaining equipment or replacing parts, the inspection and disassembly mechanism can quickly release the fixation: the hydraulic cylinder 9 is started in reverse, the push plate 10 moves upward, the sealing plate 13 is reset, the hydraulic oil pressure is released, the sealing plate 14 drives the heat-conducting fixing plate 16 to retract, and the industrial camera 12 is released for removal and maintenance. At the same time, when the push plate 10 moves downward, it drives the baffle 19 to move downward through the vertical plate 17 and the connecting rod 18. The side of the baffle 19 abuts against the connecting seat 3 to achieve secondary fixation. When maintaining the laser rangefinder 5, the push plate is moved upward to make the baffle separate from the connecting seat, and the connecting seat 3 and the ranging component on it can be easily removed, which greatly improves the efficiency of equipment maintenance. Throughout the entire process, non-contact laser measurement and image acquisition avoid physical damage to the magnesia-carbon bricks, while the modular disassembly and assembly design ensures the long-term stability and ease of maintenance of the equipment, achieving efficient and accurate detection.
