Description

Technical Field

[0002] In the machinery industry, roundness detection of large-diameter, long-span object structures (such as large pipes, containers, rotating parts, etc.) with roundness requirements has always been a major problem. In such complex scenarios, traditional roundness detection methods are often used for small or medium-sized objects due to the large size of the objects to be measured and the need for many measurement points. Traditional roundness measuring instruments are often used for small or medium-sized objects to be measured, and are difficult to adapt to the detection needs of large and long-distance objects to be measured. Operators usually need to operate the roundness instrument and the object to be measured at close range, which poses a great safety hazard. The operation at each measurement point is cumbersome and time-consuming. Most of the objects to be measured need to be adjusted and rotated during the measurement, making the entire detection process time-consuming and labor-intensive, affecting production efficiency. In addition, the installation process of traditional roundness measuring instruments is complicated and cumbersome to operate. The data collection workload is large and the repetition accuracy is low. It is difficult to unify the measurement points at the same axial position. Traditional roundness instruments are mostly contact-type measurements, and it is inevitable that scratches, wear and other damage will be caused to the surface of the object during the detection process.

[0032] In other embodiments, if the measuring component 3 includes a laser sensor 31 and a mounting base 32, the mounting base 32 is installed on the adjusting mechanism 2, and the laser sensor 31 is installed on the mounting base 32; the laser sensor 31 has high-precision non-contact measurement capabilities, effectively avoiding physical contact, reducing the risk of wear or scratches on the surface of the object to be measured, and can accurately detect tiny shape deviations of the object; the mounting base 32 serves as a supporting component between the laser sensor 31 and the adjusting mechanism 2, providing a stable installation foundation, ensuring that the laser sensor 31 maintains its position unchanged during the measurement process, effectively improving the stability of the measuring component 3, preventing the laser sensor 31 from shifting due to vibration or external force, and ensuring the accuracy of the measurement.

[0033] like Figure 1 As shown, in order to improve the flexibility and applicability of the multi-point roundness measuring device, multiple adjustment mechanisms 2 are further connected to the guide platform 1 in an adjustably positionable manner along the length direction of the guide platform 1. This design enables the multi-point roundness measuring device to adapt to objects to be measured of different lengths and diameters. For objects to be measured with large diameters or long spans, the position of the measuring component 3 can be adjusted by moving the adjustment mechanism 2, and the distribution and spacing of the measuring points can be flexibly adjusted to meet the measurement needs of objects to be measured of various specifications.

[0034] Combine Figure 1 and Figure 2 As shown, in order to facilitate the adjustment and movement of the multi-point roundness measuring device, in some embodiments, the guide platform 1 includes a column 11, a support frame 12 and a guide rail 13, the column 11 is detachably mounted on the ground, the support frame 12 is detachably mounted between the column 11 and the guide rail 13, and multiple adjustment mechanisms 2 are arranged on the guide rail 13; wherein the column 11 and the support frame 12 adopt a detachable design, so that the guide platform 1 can be easily assembled or disassembled, so that the device can be quickly disassembled and reassembled as needed during transportation, storage or on-site installation, thereby improving the flexibility of the equipment and being particularly suitable for the rapid deployment of large devices in different venues; by arranging multiple adjustment mechanisms 2 on the guide rail 13, the multiple adjustment mechanisms 2 can move freely along the direction of the guide rail 13, which enables the measuring component 3 to be flexibly positioned on the guide rail 13 according to the length of the object to be measured and the measurement requirements, thereby realizing multi-point measurement, ensuring the accurate distribution of the measurement points, and greatly improving the measurement coverage and comprehensiveness of the data.

[0035] like Figure 3As shown, in order to improve the accuracy of the multi-point roundness measuring device, in some embodiments, the adjustment mechanism 2 includes a height adjustment component 21, and the height adjustment component 21 includes a height guide and a height fixing component. The height guide is arranged on the guide platform 1, and the measuring component 3 can move on the height guide in an adjustable position along the axis direction of the object, and the height fixing component can fix the measuring component 3 at any height position of the height guide; wherein the height adjustment component 21 allows the measuring component 3 to accurately adjust its position on the height guide, so that each measuring point at the same axial position can be unified on the same height plane, ensuring the height consistency of the measuring points when measuring at different positions of the object to be measured, avoiding data errors caused by height differences of the measuring points; through the precise guidance provided by the height guide and the locking function of the height fixing component, the measuring component 3 can maintain a stable position during the measurement process, reducing measurement errors caused by vibration or displacement, greatly improving repeatability, and enabling consistent results to be obtained in multiple measurements. The measuring assembly 3 can slide freely on the height guide along the axis of the object to be measured, making it convenient for the operator to adjust the measurement point at different heights according to the size of the object to be measured and the measurement requirements, simplifying the adjustment process of the measurement point and improving the flexibility of operation. Specifically, the height guide can adopt a guide rail 13 structure, and the height fixing member can adopt a bolt structure. A guide groove is provided along the axis of the object on either the measuring assembly 3 or the guide rail 13, and a guide protrusion is provided on the other. The guide groove and the guide protrusion cooperate with each other, allowing the measuring assembly 3 to slide along the guide rail 13 to adjust its position. The bolt structure can pass through the measuring assembly 3 and be threadedly connected to the guide rail 13. After the measuring assembly 3 reaches the specified position, the operator can lock the measuring assembly 3 on the guide rail 13 by tightening the bolt. The above design takes into account the flexible adjustment and stability of the measuring assembly 3. In addition, as long as the height guide has a guiding function for the measuring assembly 3 and the height fixing has a locking function for the measuring assembly 3, the specific structures of the two are not limited.

[0036] Continue as Figure 3As shown, further, the adjustment mechanism 2 also includes an angle adjustment component 22, one end of the angle adjustment component 22 is installed on the height adjustment component 21, and can be adjusted in position along the axis direction of the object, and a measuring component 3 is installed on the other end of the angle adjustment component 22, and the measuring component 3 can rotate on the angle adjustment component 22 in a direction parallel to the length of the guide platform 1; the operator first ensures that the basic position of the measuring component 3 in the axial direction is roughly the same through the height adjustment component 21, and then further optimizes the axial position of the measuring component 3 through fine-tuning the angle adjustment component 22, so that the measuring point can be accurately adjusted to a uniform axial height, avoiding measurement errors caused by height differences, and the operator can easily adjust the angle and position of the measuring component 3 by rotating the angle adjustment component 22 to achieve precise fine-tuning without multiple manual adjustments, which greatly simplifies the operation process and reduces the difficulty of operation. Among them, the angle adjustment component 22 includes an angle adjustment platform 221, an angle adjustment plate 222 and a locking piece. The angle adjustment plate 222 is provided with an arc-shaped channel in a direction parallel to the length of the guide platform 1. The locking piece can be partially passed through the arc-shaped channel and connected to the angle adjustment platform 221. The other part of the locking piece is pressed against the side of the angle adjustment plate 222 away from the angle adjustment platform 221. The locking piece can make the angle adjustment plate 222 and the angle adjustment platform 221 in a locked or loose state. The measuring component 3 is installed on the angle adjustment platform 221. The measuring component 3 can be adjusted along the arc-shaped channel on the angle adjustment plate 222. shaped channel, the measuring component 3 can be precisely adjusted along the arc channel. The arc channel provides a finer adjustment space, so that the measuring component 3 can adjust its position more accurately along the arc channel. The arc channel makes the adjustment of the measuring component 3 smoother, avoiding the jamming or unevenness that may occur in the linear adjustment; the locking member can quickly lock or loosen the angle adjustment plate 222 and the angle adjustment platform 221. The operator only needs to perform simple adjustment and locking to complete the precise adjustment of the angle, which is more convenient to operate. At the same time, the angle adjustment platform 221 can be firmly locked in the specified position after adjustment, avoiding accidental movement of the angle adjustment platform 221 during the measurement process. Specifically, the locking member includes a fixed wrench 223, one end of which passes through an arc-shaped channel and is rotationally connected to the angle adjustment platform 221, wherein the fixed wrench 223 is connected to the angle adjustment platform 221 through a rotational connection and can provide a higher locking force; and the design of the fixed wrench 223 generally takes into account ergonomic principles, which is convenient for the operator to hold and adjust, making it more comfortable when performing locking or loosening operations.

[0037] To further improve the accuracy of the adjustment mechanism 2, in some embodiments, the height guide is provided with scale lines along the axis of the object to be measured; and / or, the angle adjustment plate 222 is provided with scale lines along the edge of the arc-shaped channel, wherein the provision of the scale lines enables the adjustment mechanism 2 to more accurately control the adjustment amplitude during operation, providing the operator with a clear numerical reference, helping the operator to more accurately locate the position of each measurement point. If a certain setting needs to be reproduced during the measurement process, the operator only needs to refer to the scale lines to adjust the adjustment mechanism 2 to the same position, ensuring comparability between multiple measurements. For situations where multiple calibrations and repeated measurements are required, the scale lines provide an intuitive reference standard to ensure the consistency of the measurement results.

[0038] To improve data processing efficiency, in some embodiments, the intelligent control component includes a data collector and a data processor, with the data collector connected to the measurement component 3 and the data processor connected to the data collector. By directly connecting the data collector to the measurement component 3, roundness data for each point detected by the measurement component 3 can be collected in real time during the measurement process, avoiding the delay of manual recording in traditional methods and reducing measurement errors. The data collector can also aggregate and transmit raw data from multiple measurement components 3 to the data processor, which can directly process, analyze, and calculate the data immediately after data collection is completed, quickly obtaining roundness data for the object to be measured. The data processor can be, but is not limited to, a computer. The data collector, data processor, and measurement component 3 can be connected via an RS485 serial port, which is not limited here.

[0039] The following is the detection process of the multi-point roundness measuring device:

[0040] First, the operator installs multiple adjustment mechanisms and multiple test components along the length of the guide platform 1 according to the size, shape and required measurement position of the object to be measured;

[0041] Secondly, according to the axis height of the object to be measured, the operator uses the height adjustment component 21 to adjust the height of each test component, so that the measuring ends of all test components can measure different positions of the object to be measured at the same axis height in a non-contact manner;

[0042] Then, open the test assembly, start the measuring instrument, observe the test point position of the test assembly, and use the angle adjustment assembly 22 to fine-tune the position of the test assembly so that each measuring point is precisely located at the same axial height of the object to be tested;

[0043] Afterwards, the intelligent control component is electrically connected to the measuring component 3, the rotating mold is started, and the testing component begins to collect the roundness data of the object to be tested. At the same time, the intelligent control component is responsible for collecting, transmitting and processing the roundness data from the testing component, and analyzing the roundness deviation of the object to be tested through a predetermined algorithm;

[0044] Finally, after waiting for the data collection to be completed, stop rotating the mold and perform data analysis.

[0045] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
