Description

Technical Field

[0001] This utility model relates to the field of roller seam measuring instrument technology, and in particular to a roller seam measuring instrument arc calibration table. Background Technology

[0002] In the metallurgical rolling process, roll gap gauges measure the roll gap angle or curvature using their built-in tilt sensors to ensure the accuracy and quality of the rolled products. However, due to long-term use, external environmental interference (such as vibration and temperature changes), or error accumulation, tilt sensors often experience linear deviations in the measurement data, which in turn affects the measurement accuracy of the roll gap gauge, resulting in uneven thickness or quality defects in the rolled products. In existing technologies, calibration equipment is mostly general-purpose machine tool error compensation systems or air gap sensor calibration devices, lacking specialized tools for measuring the curvature of the roll gap gauge's tilt sensor. The calibration process is complex, inefficient, and fails to meet the portability and high-precision requirements of on-site operation.

[0003] Currently available roll gap gauge tilt sensors suffer from linear deviation issues due to external interference and error accumulation during long-term use. This deviation often leads to a decrease in the accuracy of arc measurement, which in turn affects the overall accuracy of the metallurgical rolling process. Traditional general calibration methods have limitations such as frequent manual adjustments or high costs associated with automated equipment, resulting in a complex and inefficient calibration process.

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1: Reference Figure 1-5A roller seam gauge calibration platform includes a panel 1 and a counter-arc plate 2. The panel 1, as the main platform of the calibration platform, supports the core component of the entire calibration system. It provides a stable plane for mounting the base 3 and other calibration components. The panel 1 is made of A3 material, and its robust structure ensures overall stability during the calibration process, providing a reliable physical basis for accurate measurement. The counter-arc plate 2 is a key component in the roller seam gauge for mounting tilt sensors. During calibration, it is fixed to the vertical plate 8 of the calibration platform. Its design is compatible with the baffle 11 and L-shaped pressure block 10 on the side plate 9, ensuring that the sensor can be stably positioned during calibration. To prevent positional shifts and ensure the accuracy of angle measurements and the stability of data acquisition, a base 3 is provided on the surface of panel 1, and an indexing plate 4 is provided on the surface of base 3. A rocker arm 7 and a locking handle 6 are located on the side of the indexing plate 4. An transition plate 5 is provided on the surface of the indexing plate 4. The base 3 is fixed to the surface of panel 1, supporting the indexing plate 4. It provides a stable mounting base for the core rotating component of the calibration system, ensuring that the indexing plate 4 maintains a precise geometric position when adjusting angles. Simultaneously, the secure connection with panel 1 enhances the structural rigidity of the entire calibration table. The indexing plate 4 is the core component for calibrating angles. The core component, with precise graduations on its surface, indicates standardized calibration angles such as 0°, 30°, 60°, and 90°. The angle of the indexing plate 4 is manually adjusted via the side rocker arm 7 and secured by the locking handle 6, ensuring the tilt sensor collects data at the preset angle. Its high-precision graduation design guarantees the accuracy of angle adjustment. The transition plate 5, located on the surface of the indexing plate 4, serves as a transitional connection between the indexing plate 4 and the vertical plate 8. It ensures the vertical plate 8 is stably fixed to the indexing plate 4 and adjusts its angle synchronously with the rotation of the indexing plate 4. Simultaneously, it provides a stable mounting platform for the vertical plate 8, reducing mechanical vibration during calibration. To prevent deviation, the locking handle 6 is located on the side of the indexing plate 4. It is used to lock the position of the indexing plate 4 after the rocker arm 7 is adjusted to the target angle, ensuring the stability of the angle during the calibration process and preventing angle drift caused by external force or operation. This ensures the accuracy of sensor data acquisition and reduces the trouble of repeated adjustments due to unstable angle. The rocker arm 7 is installed on the side of the indexing plate 4 and is the operating component for manually adjusting the angle of the indexing plate 4. By shaking the rocker arm 7, the user can rotate the indexing plate 4 to preset angles such as 0°, 30°, 60° or 90°. Combined with the fixing function of the locking handle 6, the angle adjustment process is simplified and the calibration efficiency is improved.

[0018] The surface of the transition plate 5 is provided with a vertical plate 8, the surface of the vertical plate 8 is provided with a side plate 9, and the surface of the vertical plate 8 is provided with a pressure block 10. The pressure block 10 is arranged axially symmetrically on the surface of the vertical plate 8 and is L-shaped. The surface of the side plate 9 is provided with a baffle 11. The shape and position of the baffle 11 are adapted to the arc plate 2. The shape and position of the pressure block 10 are adapted to the arc plate 2. The vertical plate 8 is fixed to the surface of the transition plate 5, serving as a direct mounting platform for the arc plate 2. Its surface is provided with the L-shaped pressure block 10 and the side plate 9 to fix the arc plate 2 and ensure the positional stability of the tilt sensor during the calibration process. The vertical plate 8 rotates with the indexing plate 4, enabling the sensor to accurately align with the preset angle and support high-precision calibration. The side plate 9 is set on the surface of the vertical plate 8, forming a fixing system for the arc plate 2 together with the L-shaped pressure block 10 and the baffle 11. The baffle 11 mounted on its surface is adapted to the shape and position of the arc plate 2, restricting the lateral movement of the arc plate 2 and ensuring that it maintains the correct posture during calibration, thus enhancing the stability of the fixed structure. The pressure block 10 is L-shaped and axially symmetrically arranged on the surface of the vertical plate 8, adapted to the shape and position of the arc plate 2. The L-shaped structure tightly presses the arc plate 2, forming a three-point fixing mechanism with the baffle 11 on the side plate 9, firmly locking the arc plate 2 and preventing displacement caused by vibration or external force during calibration, thereby improving the reliability of data acquisition. The baffle 11 is located on the surface of the side plate 9, and its shape and position are precisely adapted to the arc plate 2, playing the role of restricting the lateral movement of the arc plate 2. Together with the L-shaped pressure block 10, it constitutes the fixing system of the arc plate 2, ensuring that the sensor is stable in position during calibration.

[0019] The bottom surface of panel 1 is provided with a support frame 12, the bottom surface of support frame 12 is provided with a support base 13, the surface of support base 13 is provided with support feet 14, the bottom surface of support base 13 is provided with casters 15, the side of support frame 12 is provided with corner blocks 16, and the corner blocks 16 are respectively provided on the surface of support frame 12, panel 1, and support base 13. The side of panel 1 is provided with a handle 17, and the surface of panel 1 is provided with a level 18. Support frame 12 is fixed to the bottom surface of panel 1, connecting panel 1 and support base 13, and plays the role of supporting the entire calibration platform. The corner blocks 16 on the side enhance the connection strength with panel 1 and support base 13, ensuring the overall stability of the equipment when moving or calibrating. Support base 13 is located on the bottom surface of support frame 12, serving as the direct connection between the calibration platform and the ground. The contact components include support feet 14 mounted on the surface of the support base 13, used to adjust the level of the calibration platform. By rotating the support feet 14 and cooperating with the level indicator 18 on the panel 1, the user can adjust the calibration platform to a level position in one go, ensuring the stability of the calibration environment and significantly reducing the limitations of traditional methods that require frequent manual adjustments due to unstable environments. Casters 15 are mounted on the bottom surface of the support base 13, making the calibration platform portable and easy to move in metallurgical sites or other working environments. Combined with the handle 17, the user can easily push the calibration platform to a flat surface for calibration, reducing the complexity of moving traditional fixed calibration equipment between different locations. Corner blocks 16 are respectively mounted on the surfaces of the support frame 12, panel 1, and support base 13, serving to strengthen the structural connections. By enhancing the rigidity between components, they prevent structural deformation caused by external forces during calibration, ensuring the overall stability and calibration accuracy of the calibration platform. Specific Implementation Example 2: A roller seam gauge arc calibration platform, based on the basic structure in Specific Embodiment 1, further discloses the following: When calibrating the roller seam gauge arc calibration platform, firstly, the calibration platform is moved to a flat and hard ground using the handle 17 on the side of the panel 1 and the casters 15 on the bottom of the support base 13. Then, the support feet 14 on the surface of the support base 13 are rotated, and the calibration platform is adjusted to a horizontal state in conjunction with the level 18 on the panel 1. The support feet 14 are then locked to ensure stability. Next, the arc-aligning plate 2 (including the tilt sensor) of the roller seam gauge is placed in the fixing system on the surface of the vertical plate 8, sliding in along the baffle 11 on the side plate 9, so that the arc-aligning plate 2 is adapted to the baffle 11 and the L-shaped pressure block 10. After adjusting the position of the arc-aligning plate 2, the L-shaped pressure block 10, which is symmetrically arranged on the surface of the vertical plate 8, is locked, forming a stable three-point fixation with the baffle 11. First, ensure the sensor position remains fixed. Then, manually rotate the indexing plate 4 to a preset angle (0°, 30°, 60°, or 90°) using the rocker arm 7 on the side of the indexing plate 4. After confirming the angle is accurate using the precise scale on the surface of the indexing plate 4, tighten the locking handle 6 to fix the indexing plate 4 and prevent angle deviation. Open the calibration module of the host computer software, read the output data of the tilt sensor on the arc plate 2 at the current angle, and record and save it. Then, loosen the locking handle 6 and adjust to the next preset angle using the rocker arm 7. Repeat the locking and data acquisition steps until all angles are calibrated. After calibration, the software automatically saves the deviation data to the roll gap meter to form correction parameters, which are used to automatically correct the sensor output during subsequent roll gap measurements, thereby ensuring the accuracy and reliability of arc measurement in the metallurgical rolling process.

[0021] In summary: 1. Adopting a standardized fixed angle calibration mechanism and integrated portable structural design, the sensor is manually adjusted to preset angles such as 0°, 30°, 60° and 90° via the rocker arm 7 on the side of the indexing plate 4 and fixed by the locking handle 6, ensuring that the sensor can quickly collect data in a stable position, thereby reducing the adjustment frequency and improving operating efficiency. At the same time, the L-shaped pressure block 10 symmetrically arranged on the surface of the vertical plate 8 and the baffle 11 on the side plate 9 are adapted to fix the arc plate 2, realizing the stable locking of the sensor position. Combined with the support frame 12 on the bottom of the panel 1, the support feet 14 on the support base 13 and the universal wheels 15, as well as the portable design of the side handle 17, it is easy to move on site and level in one go, significantly reducing the complexity of the calibration environment. The deviation data is automatically recorded and saved to the roll gap meter through the host computer software, forming correction parameters that can be reused for a long time, thereby comprehensively improving the measurement accuracy and overall reliability in the metallurgical rolling process.
