Description

Technical Field

[0001] The present disclosure relates to the field of precision measurement, and in particular to a method, system, and electronic equipment for measuring the precision of a motion track of a cutting machine. Background Art

[0002] Cutting machine is one of the important production equipment of shipbuilding enterprises. In order to cut high-precision steel, the accuracy of the cutting machine must be improved. However, the actual situation is that most cutting machines are overloaded and the accuracy of cutting steel gradually decreases. Improving the cutting accuracy of the cutting machine is receiving more and more attention.

[0003] In the past, the method for measuring the accuracy of the cutting machine's motion track was still based on two-dimensional manual measurement. Steel wires were pulled at both ends of the cutting machine's motion track, and a tape measure was used to measure the distance between the steel wire and the track at the same distance on the track. The distance between the steel wire and the track was repeatedly measured from one end of the track to the other, which could be converted into the track straightness deviation value. Steel wires were pulled simultaneously on both tracks, and the deviation between the steel wires was measured at the same position using a tape measure to determine the parallelism of the tracks. A level was used to measure the horizontal value of the track to determine the horizontal deviation value of the track. This method of pulling steel wires, using a tape measure and a level to measure the straightness, horizontality, and parallelism of the track is relatively backward, and the manual measurement data has large errors, which greatly reduces the accuracy of the measurement data. The accuracy errors of the above three monitoring indicators are all within the range of ±1 mm. Therefore, the data measured by this method is less accurate and cannot meet the precision requirements of the cutting machine's motion track. Summary of the Invention

In the embodiments of the present disclosure, the use of prefixes such as ordinal numbers to distinguish description objects does not constitute a limitation on the described objects.

In addition, in the description of this embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

[0049] Example 1

[0050] Figure 1 This is a flow chart of a method for measuring the accuracy of a motion track of a cutting machine provided in this embodiment. The motion track includes a main track and a secondary track. The motion track accuracy measurement method includes the following steps:

[0051] S11. Establish a three-dimensional coordinate system based on the first reference point, the second reference point and the third reference point; wherein the first reference point and the second reference point are set on the main rail, and the third reference point is set on the secondary rail; the first reference point is the coordinate origin of the coordinate system, the line connecting the first reference point and the second reference point is the first coordinate axis, the line connecting the first reference point and the third reference point is the second coordinate axis, and the perpendicular direction of the plane formed by the first coordinate axis and the second coordinate axis is the third coordinate axis.

[0052] In this embodiment, the primary rail supports the primary movement of the cutting device within the cutting machine, typically supporting the longitudinal movement of the cutting device and ensuring the straightness and accuracy of the cutting path. The secondary rail assists the primary rail, providing additional support and guidance, helping to stabilize the primary rail and, in some cases, adjusting the lateral movement of the cutting device. Therefore, both the first and second reference points are located on the primary rail to ensure the straightness and accuracy of the cutting path.

[0053] S12. Obtain coordinates of a plurality of measurement points in the coordinate system; wherein the measurement points are connection points between the motion track of the cutting machine and the foundation.

[0054] S13. Calculate a deviation value based on the coordinates of the plurality of measurement points; wherein the deviation value includes at least one of a straightness deviation value, a parallelism deviation value, and a horizontal deviation value.

[0055] S14: In response to the deviation value exceeding the corresponding accuracy threshold range, it is determined that there is an accuracy problem with the installation of the corresponding measurement point on the motion track. In this embodiment, the accuracy threshold ranges for the straightness deviation value, the parallelism deviation value, and the horizontal deviation value are all within ±1 mm. In other specific implementations, different accuracy threshold ranges can be set as needed to meet the accuracy requirements of the cutting machine motion track.

[0056] In this embodiment, a coordinate system is established based on a reference point, and the coordinates of multiple measuring points in the coordinate system are obtained. The deviation value is calculated based on the coordinates of the multiple measuring points, thereby improving the measurement accuracy and meeting the accuracy requirements of the cutting machine motion track. When the deviation value exceeds the corresponding accuracy threshold range, it indicates that there is an accuracy problem in the installation of the motion track at the corresponding measuring point. Therefore, it is convenient for the staff to determine the position that needs to be reinstalled and adjusted based on the measuring point where the accuracy problem is detected, so as to correct the motion track of the cutting machine and improve the accuracy of the cutting machine.

[0057] Furthermore, the staff can correct the installation of the corresponding measuring points according to at least one of the straightness deviation value, parallelism deviation value and horizontal deviation value, and repeat the above measurement process. The operation method is simple and efficient until the deviation value meets the accuracy threshold range, thereby ensuring that the accuracy of the cutting machine's motion track meets the standard requirements, so as to ensure the accuracy of the material to be cut in subsequent cutting.

[0058] In a specific example, Figure 2 The schematic diagram of the structure of a cutting machine includes a cutting machine carriage 21, a cutting machine trolley 22, a cutting torch 23, a frame and a cutting platform 24. The frame includes a main frame 25, a sub-frame 26 and a crossbeam 27. The crossbeam 27 is provided with a cutting machine trolley track 28. Figure 2 The motion track in the vehicle includes a main track 29 and a secondary track 210 .

[0059] The cutting machine trolley 21 is arranged on the main frame 25 in the frame. The cutting machine trolley 21 moves along the main rail 29 of the cutting machine, thereby driving the frame to move on the motion track.

[0060] The cutting machine trolley 22 is connected to the cutting torch 23, and the cutting machine trolley 22 is used to drive the cutting torch 23 to move.

[0061] The cutting platform 24 is used to place the material to be cut. The cutting machine trolley 22 is used to move along a preset route on the cutting machine trolley track 28, so that the cutting torch 23 cuts the material to be cut on the cutting platform 24 along the preset route.

[0062] As can be seen, when there are accuracy issues with the installation of the motion track, the cutting accuracy of the cutting torch will be affected. Therefore, the motion track accuracy measurement method provided in this embodiment can effectively solve the motion track accuracy problem. Moreover, the motion track accuracy measurement method in this embodiment is simple. During the specific implementation process, all deviation values ​​​​as monitoring data can be extracted after a single measurement is completed, and a data report is generated. The data report is fed back to the maintenance worker. After manual and mechanical correction, the accuracy requirements are finally met, thereby improving the cutting accuracy of the cutting machine and achieving the ultimate goal of reducing costs and increasing efficiency.

[0063] In an optional embodiment, the first reference point is the starting point of the connection between the main rail and the foundation in the area to be measured, the second reference point is the final point of the connection between the main rail and the foundation in the area to be measured, and the third reference point is the starting point of the connection between the secondary rail and the foundation in the area to be measured; the first coordinate axis is the horizontal axis, the second coordinate axis is the vertical axis, and the third coordinate axis is the vertical axis.

[0064] The measuring points include several groups of correspondingly set first measuring points and second measuring points, wherein the first measuring points are the connection points between the main rail and the foundation, and the second measuring points are the connection points between the auxiliary rail and the foundation. In a specific example, since the moving track of the cutting machine is usually designed in sections, each section of the main rail and the auxiliary rail is set accordingly. Every two sections of the main rail in the moving track are connected by a connector to form a connection point; every two sections of the auxiliary rail are connected by a connector to form a connection point; the connection point is used to connect and fix with the foundation to ensure the stability of the moving track. Therefore, the connection point between the main rail and the foundation can be used as the first measuring point, and the measurement point between the auxiliary rail and the foundation can be used as the second measuring point.

[0065] In this embodiment, the coordinates of the first reference point are set to (0, 0, 0) as the origin of the three-dimensional coordinate system. The first coordinate axis is the horizontal axis (X-axis), the second coordinate axis is the vertical axis (Y-axis), and the third coordinate axis is the vertical axis (Z-axis). The position data of the measurement point is converted to the corresponding coordinates in the three-dimensional coordinate system, thereby facilitating the calculation of the deviation value of the motion trajectory.

[0066] In a specific embodiment, Figure 3 As shown, the starting point of the connection between the main rail and the foundation is taken as the first reference point A1, the final point of the connection between the main rail and the foundation is taken as the second reference point A2, and the starting point of the connection between the auxiliary rail and the foundation is taken as the third reference point A3. i and the second measuring point C iis a set of corresponding measurement points, wherein i takes any value among 1, 2, and 3. In addition, in other implementations, different groups of measurement points can be set according to actual conditions.

[0067] In an optional embodiment, the straightness deviation value includes a main rail straightness deviation value and a secondary rail straightness deviation value, and step S13 specifically includes:

[0068] According to the difference between the ordinates of the first measuring point and the coordinate origin, the straightness deviation value of the main track corresponding to the first measuring point is obtained. Figure 3 For example, calculate the first measurement point B i The difference between the ordinate and the coordinate origin (0, 0, 0) is used to obtain the main rail straightness deviation value corresponding to the first measuring point.

[0069] According to the difference between the ordinate of the second measuring point and the preset track gauge, the straightness deviation value of the secondary rail corresponding to the second measuring point is obtained. Figure 3 For example, calculate the second measurement point C i The difference between the gauge F and the preset gauge F is used to obtain the secondary rail straightness deviation value corresponding to the second measuring point.

[0070] In an optional embodiment, step S13 specifically includes:

[0071] According to the difference between the ordinates of the first measuring point and the corresponding second measuring point, the parallelism deviation value between the main rail and the auxiliary rail is obtained. Figure 3 For example, the differences between B1 and C1, B2 and C2, and B3 and C3 on the Y-axis coordinates are calculated to obtain the actual track gauges of the corresponding connection points of the main rail and the auxiliary rail. The actual track gauges are compared with the preset track gauge F to calculate the difference between the actual track gauge and the preset track gauge, that is, the parallelism deviation value of the main rail and the auxiliary rail.

[0072] In an optional embodiment, the horizontal deviation value includes a main rail horizontal deviation value and a secondary rail horizontal deviation value, and step S13 specifically includes:

[0073] According to the vertical coordinate difference between the first measurement point and the coordinate origin, the horizontal deviation value of the main track corresponding to the first measurement point is obtained. Figure 3 For example, calculate B i The vertical coordinate difference between the first measuring point and the coordinate origin (0, 0, 0) is used to obtain the horizontal deviation value of the main rail corresponding to the first measuring point.

[0074] According to the vertical coordinate difference between the second measurement point and the coordinate origin, the horizontal deviation value of the secondary track corresponding to the second measurement point is obtained. Figure 3 For example, calculate C iThe vertical coordinate difference between the vertical coordinate of the coordinate origin (0, 0, 0) and the horizontal deviation value of the secondary track corresponding to the second measuring point is obtained.

[0075] In an optional embodiment, before step S11, the method further includes:

[0076] The position data of the target point is obtained according to the total station; wherein the target point includes the first reference point, the second reference point, the third reference point and a plurality of measurement points, and the position data is used to generate the coordinates of the corresponding target point according to the coordinate system.

[0077] The position data includes a horizontal angle, a vertical angle, and a slant distance; the horizontal angle is the horizontal angle of the target point relative to the initial direction of the total station, the vertical angle is the vertical angle of the target point relative to the horizontal plane, and the slant distance is the straight-line distance from the target point to the total station.

[0078] In this embodiment, if Figure 4 As described, the target point is marked on the motion track. Specifically, a prism can be set at the target point to ensure that the center of the prism coincides with the target point, so that the measurement can be performed by aiming the total station at the prism on the target point. After confirming that the cutting machine to be measured is in a stopped state and the motion track is free of debris and obstructions, the total station is placed in front of the cutting machine and set to measurement mode to ensure that the motion track to be measured is within the measurement range of the total station. The position data of all target points can be collected, thereby facilitating the subsequent setting of the first reference point, the second reference point, and the third reference point to generate a three-dimensional coordinate system based on the position data of the three points.

[0081] Figure 5 This is a module diagram of a motion track accuracy measurement system for a cutting machine provided by an embodiment of the present invention. The motion track includes a main track and a secondary track. The motion track accuracy measurement system 50 for the cutting machine includes:

[0082] The coordinate system establishment module 501 is used to establish a three-dimensional coordinate system based on a first reference point, a second reference point and a third reference point; wherein the first reference point and the second reference point are set on the main rail, and the third reference point is set on the secondary rail; the first reference point is the coordinate origin of the coordinate system, the line connecting the first reference point and the second reference point is the first coordinate axis, the line connecting the first reference point and the third reference point is the second coordinate axis, and the perpendicular direction of the plane formed by the first coordinate axis and the second coordinate axis is the third coordinate axis.

[0083] The coordinate acquisition module 502 is used to acquire the coordinates of multiple measurement points in the coordinate system; wherein the measurement points are the connection points between the motion track of the cutting machine and the foundation.

The deviation value is calculated based on the coordinates of the multiple measuring points, thereby improving the measurement accuracy and meeting the accuracy requirements of the cutting machine motion track. When the deviation value exceeds the corresponding accuracy threshold range, it indicates that there is an accuracy problem in the installation of the motion track at the corresponding measuring point. Therefore, it is convenient for the staff to determine the position that needs to be reinstalled and adjusted based on the measuring point where the accuracy problem is detected, so as to correct the motion track of the cutting machine and improve the accuracy of the cutting machine.

[0087] Furthermore, the staff can correct the installation of the corresponding measuring points according to at least one of the straightness deviation value, parallelism deviation value and horizontal deviation value, and repeat the above measurement process.
