Description

Technical Field

[0002] The standard wheelset is a standard basis for wheelset processing quality assessment, a lathe measurement accuracy assessment device, and a measuring tool for calibration of wheelset running geometric parameter detection system. The existing basic tools for standard wheelset geometric parameters are: wheelset internal distance gauge, wheel position difference measuring device, digital axle full length ruler, scale axle shoulder distance gauge, diameter measuring instrument, micrometer and other conventional measuring tools for measurement. The measurement of these measuring tools is mainly based on manual measurement, recording and analysis, supplemented by additional measurement data input into the computer for statistical analysis. These tools have poor measurement accuracy and lack of traceability benchmarks and related measurement methods. In addition, the manual measurement and recording process is prone to problems such as inaccurate data, missed measurements and wrong recording, resulting in inaccurate and imperfect traceability of wheelset geometric parameters, which in turn causes the imperfect standard wheelset accuracy evaluation system and makes it difficult to achieve traceability.

[0067] The standard wheelset 5 is a wheelset that has been precisely manufactured and has dimensions that meet strict tolerance requirements. It consists of an axle 52, a first wheel 50, a second wheel 51, two brake discs 53 and other auxiliary structures. As a standard basis for wheelset processing quality assessment, a lathe measurement accuracy assessment device and a measuring tool for calibrating the wheelset running geometric parameter detection system, the accuracy of its geometric parameters will have a great impact on the lathe accuracy and the wheelset accuracy after lathe repair, and the measurement of wheelset geometric parameters. Therefore, the measurement accuracy of the standard wheelset 5 is particularly important. The wheel lathe is a special machine tool for daily and overhaul of wheels. The accuracy of its measurement affects not only the wheel processing quality, but also the safety of train operation. Comparing the geometric parameters measured by the standard wheelset 5 on the lathe with the actual geometric parameters of the standard wheelset 5 can realize the evaluation of the lathe accuracy retention, timely discover and correct the lathe deviation, keep the lathe processing performance in the best state, and provide a basic tool for the accuracy measurement of wheelset lathe repair.

[0068] As a special measuring tool for daily and periodic calibration of the lathe, the standard wheel set 5 itself will also produce wear. Therefore, it is necessary to accurately measure the geometric parameters of the standard wheel set 5 to ensure the accuracy of its geometric parameters.

[0069] Reference Figure 1 The fully automatic high-precision wheelset measurement traceability detection device according to an embodiment of the present invention includes a first support structure 6, a second support structure 7 and a scanning structure.

[0070] The first support structure 6 is used to support the axle 52 of the standard wheel set 5, and the first support structure 6 does not contact the first wheel 50, the second wheel 51 and the two brake discs 53, so as to avoid affecting the scanning of the wheel geometric parameters when supporting. The first support structure 6 can also rotate the standard wheel set 5, so that the scanning structure can completely scan the geometric parameters of the first wheel 50 and the second wheel 51 respectively without making significant adjustments. For example, when it is necessary to scan the first wheel 50, the first support structure 6 rotates the first wheel close to the scanning structure, and the scanning structure scans it; after the scanning of the first wheel 50 is completed, the first support structure 6 drives the standard wheel set 5 to rotate again, so that the second wheel 51 rotates close to the scanning structure without moving the scanning structure. At this time, the scanning structure can scan the geometric parameters of the second wheel 51.

[0071] The second support structure 7 is used to support the first wheel 50 and the second wheel 51 of the standard wheel set 5, and does not contact the axle 52 and the brake disc 53, so that the scanning structure can completely scan the positions of the axle 52 and the brake disc 53 that need to be detected, avoiding the second support structure 7 from affecting the scanning of the axle 52 and the brake disc 53 when supporting. In addition, the contact area between the second support structure 7 and the first wheel 50 and the second wheel 51 is small, which reduces the shielding of the rest of the first wheel 50 and the second wheel 51, so that the scanning structure can obtain more complete geometric parameter data.

[0072] Reference Figure 2 The first support structure 6 includes a driving structure 61 and a support structure 66. The driving structure 61 is connected to the support structure 66 and drives the support structure 66 to rotate. The support structure 66 contacts the axle 52 of the standard wheelset 5 and provides support. When supporting, the support structure 66 is located between the first wheel 50 and the second wheel 51 and the brake disc 53, so that the scanning area of ​​the first wheel 50 and the second wheel 51 is not blocked, so as to facilitate the complete scanning of the first wheel 50 and the second wheel 51. When it is necessary to rotate the standard wheelset 5, the driving structure 61 drives the standard wheelset 5 to rotate through the support structure 66, so that the first wheel 50 and the second wheel 51 can be rotated in turn to be close to the scanning structure, so that the scanning structure can complete the scanning of the geometric parameters. Using the first support structure 6 to rotate the standard wheelset 5 can reduce the errors caused by manual operation, more accurately determine the rotation angle and rotation direction, and improve the accuracy of subsequent measurements.

[0073] In some embodiments, reference Figure 2 The driving structure 61 includes a turbine bracket 64, a turbine assembly 65, a worm assembly 62 and a first motor 63. The turbine bracket 64 is used to accommodate and support the turbine assembly 65, the worm assembly 62 and the first motor 63, and the turbine assembly 65 is rotatably arranged in the turbine bracket 64. The worm assembly 62 is arranged on one side of the turbine bracket 64, and the worm assembly 62 is transmission-connected with the turbine assembly 65. The worm in the worm assembly 62 and the turbine in the turbine assembly 65 form a set of turbine worm structure. The first motor 63 is installed on one side of the turbine bracket 64, and is transmission-connected with the worm assembly 62, and drives the turbine to rotate through the turbine worm structure, thereby further driving the turbine assembly 65. In other implementations, the driving structure 61 can also be any structure in the prior art that can realize rotation, such as a motor, a cylinder, etc.

[0074] The support structure 66 is connected to the turbine assembly 65, and different methods can be used for connection according to actual conditions. For example, it is connected by a plurality of bolts 68, and the plurality of bolts 68 can be dispersedly distributed or arranged in an orderly manner, such as being arranged in two groups in an arc shape. When the driving structure 61 is required to drive the support structure 66 to rotate, the first motor 63 drives the worm in the worm assembly 62 to rotate, and the worm drives the turbine, and further drives the support structure 66 to rotate through the turbine assembly 65, so as to realize the rotation of the standard wheelset 5. The rotation driven by the first motor 63 and the turbine worm structure can reduce the error caused by manual operation, more accurately determine the rotation angle and rotation direction, and improve the accuracy of subsequent measurements.

[0075] In some embodiments, reference Figure 2 The support structure 66 includes a connection plate 67 and two support bodies 69. The connection plate 67 is connected to the turbine assembly 65. When the turbine assembly 65 rotates, the connection plate 67 also rotates. The two support bodies 69 are symmetrically connected to the two sides of the connection plate 67, and the top of the support body 69 is a fork. According to actual conditions, the fork can be in a variety of shapes, such as Y-shaped, U-shaped or trapezoidal. Figure 3 When the standard wheelset 5 is placed on the support structure 66, the axle 52 is placed in the two forked parts, and at this time, the two forked parts are located between the first wheel 50, the second wheel 51 and the two brake discs 53 of the standard wheelset 5. The support body 69 supports the axle 52 of the standard wheelset 5, and can effectively support the wheels and the brake discs 53 while avoiding the waiting measurement position, thereby avoiding the influence of the support body 69 on the geometric parameter detection of the standard wheelset 5.

[0076] Reference Figure 1 , Figure 4 , there are two second support structures 7, which are located on both sides of the first support structure 6. After the standard wheelset 5 located on the first support structure 6 is rotated, the vertical projections of the first wheel 50 and the second wheel 51 can correspond to the two second support structures 7 respectively, so that the standard wheelset 5 can be transferred from the first support structure 6 to the two second support structures 7 for support, so as to facilitate the detection of different parts of the standard wheelset 5. The two second support structures 7 are respectively used to contact and support the first wheel 50 and the second wheel 51 of the standard wheelset 5, so that the scanning structure can scan the geometric parameters of the rest of the standard wheelset, such as the wheel inner side distance, brake disc thickness and brake disc center distance of the standard wheelset.

[0077] The second support structure 7 can also move the standard wheelset 5 in the height direction, so that the standard wheelset 5 can be separated from the first support structure 6, so as to avoid the problem that the scanning area is blocked and the complete geometric parameters cannot be obtained when the scanning structure detects the rest of the standard wheelset. According to the actual situation, when multiple measurements are required to improve the data accuracy, the second support structure 7 can also drive the standard wheelset 5 to rotate, so that the scanning structure can perform multiple scans at different positions of the standard wheelset 5 along the circumferential direction, so as to calculate the average value, obtain more accurate geometric parameters, reduce measurement errors, and improve measurement accuracy.

[0078] In some embodiments, reference Figure 4 , the second support structure 7 includes a support frame 72, a lifting assembly 73, a support wheel 71, a driving wheel 74 and a second motor 76. The top of the lifting assembly 73 is connected to the support frame 72. The lifting of the lifting assembly 73 can drive the support frame 72 to move in the height direction, realize the lifting and lowering of the standard wheel set 5, avoid the risk of tilting and falling caused by manual operation, improve the degree of automation of measurement, reduce errors, and improve the detection accuracy. The lifting assembly may specifically be a lifting cylinder, a motor and other structures. The support wheel 71 and the driving wheel 74 are respectively rotatably connected to the two ends of the top surface of the support frame 72, contact the first wheel 50 and the second wheel 51 of the standard wheel set 5, and provide support for the standard wheel set 5. The driving wheel 74 can also drive the standard wheel set 5 to rotate around its axle 52, so as to facilitate multi-point scanning along the circumferential direction of the standard wheel set 5 and increase the accuracy of measurement. The second motor 76 is connected to the driving wheel 74 in a transmission manner to provide power for the driving wheel 74 to rotate.

[0079] In some embodiments, reference Figure 4 The second support structure 7 further includes a first synchronous pulley 77, a second synchronous pulley 78 and a synchronous belt 75. The first synchronous pulley 77 is connected to the end of the second motor 76, the second synchronous pulley 78 is connected to the end face of one side of the driving wheel 74, and the synchronous belt 75 is connected to the first synchronous pulley 77 and the second synchronous pulley 78 respectively. When the driving wheel 74 needs to be driven to rotate, the second motor 76 drives the first synchronous pulley 77 to rotate, and the first synchronous pulley 77 drives the synchronous belt 75 to rotate. The second synchronous pulley 78 rotates synchronously with the driving wheel 74, and driven by the synchronous belt 75, the second synchronous pulley 78 further drives the driving wheel 74 to rotate. The two driving wheels 74 drive the standard wheel pair 5 placed on the driving wheel 74 to rotate through the first wheel 50 and the second wheel 51. The second motor 76 is connected to the driving wheel 74 in transmission, providing power for the driving wheel 74 to rotate. The rotation of the standard wheel pair 5 enables the scanning structure to perform multi-point scanning along the circumferential direction of the standard wheel pair 5, thereby increasing the accuracy of the measurement.

[0080] In actual situations, the two second support structures 7 operate synchronously. That is to say, the lifting and lowering of the two lifting assemblies 73 and the rotation of the two driving wheels 74 driven by the two second motors 76 are all performed synchronously. Since the two second support structures 7 are in contact with and provide support for the first wheel 50 and the second wheel 51 respectively, when the two second support structures 7 cannot operate synchronously, the lifting heights and rotation speeds on both sides of the standard wheel set 5 are different, which will cause the standard wheel set 5 to tilt or even fall, causing an accident. At the same time, the synchronous operation of the second support structures 7 on both sides also allows the weight of the standard wheel set 5 to be effectively dispersed, avoiding structural damage caused by excessive pressure on the second support structure 7 on one side.

[0081] Reference Figure 1 The scanning structure includes a scanning component 4, a mechanical arm 3 and a moving component 1, which are used to obtain the geometric parameters of different positions of the standard wheelset 5. The scanning structure is arranged on one side of the first support structure 6 and the two second support structures 7, and is located between the two second support structures 7. According to actual conditions, the scanning structure can be arranged on the midline of the line connecting the two second support structures 7, or there may be a certain offset near the midline. The mechanical arm 3 is installed on the moving component 1, which is convenient for adjusting the mechanical arm 3 to a suitable position according to the position to be measured on the standard wheelset 5, so as to avoid the position to be measured being located at the edge or outside of the scanning area, resulting in inaccurate or missing measurement data, and affecting the accuracy of the measurement. The scanning component 4 is installed at the end of the mechanical arm 3, and the mechanical arm 3 drives the scanning component 4 to move to scan the geometric parameters of the standard wheelset 5.

[0082] In some embodiments, reference Figure 1 The moving assembly 1 includes a vertical moving structure 11 and a linear feeding structure 13. The vertical moving structure 11 is connected to the robot arm 3 and is used to drive the robot arm 3 along the height direction, that is, Figure 1 The vertical moving structure 11 is installed on the linear feeding structure 13, and the linear feeding structure 13 can drive the vertical moving structure 11 along the horizontal direction, that is, Figure 1 The vertical moving structure 11 and the linear feed structure 13 can move in the y-axis direction. The structures of the vertical moving structure 11 and the linear feed structure 13 can be the same or different. The vertical moving structure 11 and the linear feed structure 13 can adopt structures such as ball screw modules or linear guide modules to achieve movement in the straight line direction. For example, when the vertical moving structure 11 and the linear feed structure 13 are both ball screw slide modules, the vertical moving structure 11 is installed on the slide of the linear feed structure 13, and the robot arm 3 is set on the slide of the vertical moving structure 11. The movement of the position of the robot arm 3 is achieved by adjusting the two slides. By adjusting the vertical moving structure 11 and the linear feed structure 13, the robot arm 3 can be adaptively moved in the z-axis and y-axis directions according to the detection requirements, thereby improving the accuracy of the measurement of the geometric parameters of the wheelset and reducing the errors caused by manual measurement.

[0083] According to actual conditions, the moving assembly 1 may further include another structure that moves in a linear direction, which is used to adjust the position of the robot arm 3 in the x-axis direction. For example, when the straight line where the center line of the linear feed structure 13 is located is offset too much from the rotation center of the turbine assembly 65 of the first support structure 6, the robot arm 3 needs to be moved in the x-axis direction to avoid excessive geometric parameter measurement errors that affect the detection accuracy.

[0084] In some embodiments, reference Figure 5-Figure 6 The scanning assembly 4 includes a plurality of sensors 41 and a mounting plate 42. The mounting plate 42 is connected to the end of the mechanical arm 3 and is controlled by the mechanical arm 3 to detect different positions of the standard wheel set 5. A plurality of sensors 41 are mounted on both sides of the mounting plate 42 along the length direction. The width of the scanning area formed by the combination of the plurality of sensors 41 is greater than the thickness of the first wheel 50 and the second wheel 51, so as to measure the first wheel 50 and the second wheel 51 more completely and reduce the measurement error. The number of sensors 41 can be changed according to actual conditions. For example, two sensors 41 are respectively mounted on both sides of the mounting plate 42 along the length direction. When the first wheel 50 and the second wheel 51 are scanned with separate wheel geometric parameters, the two sensors 41 can simultaneously scan both sides of the wheel surface of the first wheel 50 or the second wheel 51 close to the two end surfaces. At this time, the robot arm 3 does not need to move back and forth on the two end surfaces of the first wheel 50 and the second wheel 51, so that the sensor 41 can obtain their geometric parameter data. When scanning the axle 52 and the brake disc 53, the two sensors can simultaneously scan the axle 52 and the brake disc 53 near both sides along their axes. At this time, the robot arm does not need to move back and forth on the axle 52 and the brake disc 53 in the circumferential direction, so that the sensor 41 can obtain their geometric parameter data. By setting up multiple sensors 41, the accumulated errors caused by the adjustment process of the robot arm 3 are reduced, and the accuracy of detection is improved.

[0085] The position of the scanning component 4 is adjusted by the moving component 1 and the mechanical arm 3. The scanning component 4 rotates around its rotation center during scanning. Before scanning the standard wheel pair 5, the rotation center coordinates of the scanning component 4 need to be adjusted by the mechanical arm 3. According to actual conditions, the mechanical arm 3 can use a 6-axis mechanical arm to achieve more precise and flexible adjustment, improve the degree of detection automation, and effectively improve the accuracy and efficiency of detection. In some embodiments, the detection device also includes a control structure. The control structure is respectively connected to the first support structure 6, the second support structure 7, the scanning component 4, the mechanical arm 3 and the moving component 1. The control structure can control the first support structure 6 and the second support structure 7 to drive the standard wheel pair 5 to rotate, control the moving component 1 to drive the mechanical arm 3 to drive the scanning component 4 to move, and control the mechanical arm 3 to drive the scanning component 4 to scan the geometric parameters of the standard wheel pair 5. The specific control process can refer to the following detection method. The control structure is adopted to improve the accuracy and automation of the measurement of the geometric parameters of standard wheelset 5, reduce the error caused by manual measurement, and provide more accurate and reliable data for subsequent value traceability, wheelset structure analysis, accuracy degradation analysis, wheelset service life prediction and determination of wheelset uncertainty level.

[0086] Reference Figure 7 The embodiment of the present invention provides a method for fully automatic high-precision wheel set measurement traceability detection. The detection method is based on the above-mentioned fully automatic high-precision wheel set measurement traceability detection device, and is used to measure the geometric parameters of the standard wheel set 5, and further process them to provide more accurate and reliable data for subsequent measurement traceability and determination of wheel set uncertainty level. When obtaining the geometric parameters, the standard wheel set 5 is divided into the first wheel 50, the second wheel 51 and the rest, and the detection method includes:

[0087] Step S1: Install the standard wheelset on the first support structure, and control the first support structure to drive the standard wheelset to rotate until the central axis of the standard wheelset is parallel to the moving direction of the linear feed structure and the first wheel is close to the moving assembly.

[0088] Specifically, refer to Figure 1 , Figure 3 When the standard wheelset 5 is placed on the first support structure 6, the two ends of the axle 52 between the first wheel 50 and the brake disc 53 and between the second wheel 51 and the brake disc 53 are in contact with the forked portion of the support body 69, and the standard wheelset 5 is suspended and supported by the support body 69. In order to scan the first wheel 50, it is necessary to rotate the standard wheelset 5 so that the first wheel 50 is close to the moving assembly 1, and the central axis of the standard wheelset 5 is parallel to the moving direction of the linear feed structure 13.

[0089] The control structure controls the first motor 63 to operate, and the worm of the worm assembly 62 drives the turbine, so that the turbine assembly 65 rotates in the turbine bracket 64. The turbine assembly 65 further drives the connecting plate 67 connected thereto to rotate, so that the bracket body 69 rotates, and drives the standard wheel set 5 to rotate in the direction of making the first wheel 50 close to the moving assembly 1, until the central axis of the standard wheel set 5 is parallel to the moving direction of the linear feed structure 13, so as to scan the first wheel 50 of the standard wheel set 5 next.

[0090] Step S2: setting a plurality of calibration points on the first wheel, controlling the scanning component to scan the plurality of calibration points of the first wheel, and calculating and obtaining the wheel radius and the wheel center of the first wheel.

[0091] A sensor 41 with a system accuracy of ±0.01 mm and a robot arm 3 with a trajectory accuracy of ±0.01 mm are selected in combination to reduce errors during scanning and ensure measurement accuracy. The system accuracy of the measurement obtained by the combination can be ±0.03 mm.

[0092] Reference Figure 8 , multiple calibration points at different positions on the same plane are marked on the raised rim of the first wheel 50. According to actual conditions, three calibration points can be set, namely point A, point B, and point C. By setting multiple calibration points to calibrate the scanning component 4, the error in the formal scanning can be reduced, the detection efficiency can be improved, and the measurement accuracy can be improved.

[0093] The control system controls the moving component 1 to move the scanning component 4 to scan the three calibration points of the first wheel 50. When the robot arm 3 reaches the maximum length and still cannot make the first wheel 50 fall into the scanning area, the sensor 41 cannot scan the three calibration points. The control structure controls the linear feed structure 13 to drive the vertical moving structure 11 and the robot arm 3 and the scanning component 4 to move toward the first wheel 50 until the first wheel 50 completely falls into the scanning area of ​​the scanning component 4 in the thickness direction. At this time, the plane where the three calibration points are located overlaps with the scanning area of ​​the sensor 41.

[0094] The control structure controls the mechanical arm 3 to drive the sensor 41 to pass through point A, point B, and point C respectively and scan them to obtain their position coordinates. According to the position coordinates of point A, point B, and point C, the wheel radius value and the wheel center coordinates of the first wheel 50 can be calculated, and the position of the wheel center is recorded as O1.

[0095] Step S3: determining a first rotation radius and a first rotation center of the scanning assembly according to the wheel radius and the wheel center of the first wheel.

[0096] Reference Figure 8-Figure 9After obtaining the wheel radius value and the coordinates of the wheel center O1 of the first wheel 50, the point coaxial with the wheel center O1 on the plane where the end of the mechanical arm 3 connected to the vertical moving structure 11 is located is taken as the first rotation center. The control structure calculates the value of the first rotation radius according to the coordinates of the rotation center around which the scanning component 4 rotates and the wheel radius, so that when the scanning component 4 rotates around the rotation center, the area formed by its first rotation radius can cover the area to be scanned of the first wheel 50. At this time, there is a deviation between the rotation center of the scanning component 4 when it rotates and the first rotation center, and the coordinates of the rotation center are marked as O2.

[0097] Step S4: controlling the rotation center of the scanning component to move to coincide with the first rotation center through the moving component, and adjusting the scanning radius of the scanning component to the first rotation radius through the mechanical arm.

[0098] Specifically, the control structure moves the rotation center O2 of the scanning component 4 according to the actual situation. When the rotation center O2 and the first rotation center are basically overlapped in projection on the x-axis, only the vertical moving structure 11 and the linear feed structure 13 are controlled to adjust the positions of the mechanical arm 3 and the scanning component 4 on the z-axis and the y-axis. Combined with the adjustment of the mechanical arm 3, the rotation center O2 can be moved to coincide with the first rotation center. When there is a certain offset between the rotation center O2 and the first rotation center in projection on the x-axis, that is, when the straight line where the center line of the linear feed structure 13 is located and the rotation center of the turbine assembly 65 are offset too much, the moving component 1 can also include another structure that moves in a straight line direction. The control structure controls the structure to adjust the positions of the mechanical arm 3 and the scanning component 4, and combines the adjustment of the mechanical arm 3 to realize the movement of the rotation center O2. At this time, the value of the first rotation radius is adjusted to the scanning radius of the scanning component 4.

[0099] Step S5: Control the mechanical arm to drive the scanning assembly to rotate and scan to obtain the geometric parameters of the first wheel.

[0100] The control structure controls the robot arm 3 to rotate the scanning assembly 4 around the rotation center O2 with a first rotation radius, so as to scan the geometric parameters of the entire circumferential direction of the first wheel 50. At this time, the first wheel 50 completely falls into the scanning area of ​​the scanning assembly 4 in the thickness direction, and multiple sensors 41 scan the first wheel 50 to obtain its geometric parameters. The geometric parameters obtained at this time include rim thickness, rim height, rim width and QR value, where the QR value is the axial distance from the wheel rim thickness measurement point to the vertex of the contour on the same side of the rim 2 mm downward. Based on these parameters, the measurement accuracy of the standard wheelset 5 can be preliminarily judged.

[0101] Step S6: Control the first supporting structure to drive the standard wheelset to rotate 180° so that the second wheel is close to the moving assembly.

[0102] After the geometric parameter scanning of the first wheel 50 is completed, the standard wheelset 5 needs to be rotated through the first support structure 6 so that the second wheel 51 is close to the scanning structure to scan the geometric parameters of the second wheel 51. The control structure controls the moving assembly 1 to move the scanning assembly 4 to prevent the standard wheelset 5 from colliding with the scanning assembly 4 when rotating. The control structure controls the first motor 63 to operate, and the worm of the worm assembly 62 drives the turbine, so that the turbine assembly 65 rotates in the turbine bracket 64, and further drives the connecting disk 67 connected thereto to rotate, so that the bracket body 69 rotates, and drives the standard wheelset 5 to rotate 180°, so that the second wheel 51 is close to the moving assembly 1.

[0103] Step S7: setting a plurality of calibration points on the second wheel, controlling the scanning component to scan the plurality of calibration points of the second wheel, and calculating and obtaining the wheel radius and wheel center of the second wheel.

[0104] In order to further improve the accuracy of measurement and provide more reliable data, it is necessary to calibrate the scanning component 4 again before the formal scanning of the second wheel 51. Mark multiple calibration points at different positions on the same plane on the raised rim of the second wheel 51. Three calibration points can be set according to actual conditions. The control system controls the moving component 1 to move the scanning component 4 to scan the three calibration points of the second wheel 51, and repeats the steps of scanning the calibration points on the first wheel 50. The moving component 1 adjusts the scanning position of the scanning component 4 so that the second wheel 51 completely falls into the scanning area of ​​the scanning component 4 in the thickness direction. Control the mechanical arm 3 to drive the sensor 41 to pass through the three calibration points respectively to obtain their position coordinates. According to the position coordinates of the three calibration points, the wheel radius value and the wheel center coordinates of the first wheel 50 can be calculated.

[0105] Step S8: Determine a second rotation radius and a second rotation center of the scanning assembly according to the wheel radius and the wheel center of the second wheel.

[0106] After obtaining the wheel radius value and the wheel center coordinates of the second wheel 51, the point coaxial with the wheel center on the plane where the end of the mechanical arm 3 connected to the vertical moving structure 11 is located is taken as the second rotation center, and the control structure calculates the value of the second rotation radius according to the coordinates of the rotation center around which the scanning component 4 rotates and the wheel radius, so that when the scanning component 4 rotates around the rotation center, the area formed by its second rotation radius can cover the area to be scanned of the second wheel 51. At this time, there is a deviation between the rotation center of the scanning component 4 when it rotates and the second rotation center.

[0107] S9: Control the rotation center of the scanning component to move to coincide with the second rotation center through the moving component, and adjust the scanning radius of the scanning component to the second rotation radius through the robotic arm.

[0108] Specifically, the control structure moves the rotation center O2 of the scanning component 4 according to the actual situation. Repeat the adjustment of the coordinate position of the rotation center by the mobile component 1. When the straight line where the center line of the linear feed structure 13 is located is offset too much from the rotation center of the turbine component 65, the mobile component 1 can also include another structure that moves in the straight line direction. The control structure controls the structure to adjust the position of the robot arm 3 and the scanning component 4, and combines the adjustment of the robot arm 3 to realize the movement of the rotation center O2. At this time, the value of the second rotation radius is adjusted to the scanning radius of the scanning component 4.

[0109] Step S10: Control the robotic arm to drive the scanning assembly to rotate and scan to obtain geometric parameters of the second wheel.

[0110] The control structure controls the robot arm 3 to drive the scanning assembly 4 to rotate around the center of the rotation circle at a second rotation radius to scan the geometric parameters of the entire circumferential direction of the second wheel 51. At this time, the first wheel 50 completely falls into the scanning area of ​​the scanning assembly 4 in the thickness direction, and the multiple sensors 41 scan the second wheel 51 to obtain its geometric parameters.

[0111] Step S11: Control the first support structure to drive the standard wheelset to rotate by a predetermined angle until the first wheel and the second wheel are located directly above the two second support structures.

[0112] After completing the scanning of the geometric parameters of the second wheel 51, the standard wheelset 5 needs to be rotated through the first support structure 6 so as to measure the remaining geometric parameters of the standard wheelset 5, namely, the wheel inner side distance, brake disc thickness and brake disc center distance of the standard wheelset. The control structure controls the moving component 1 to move the scanning component 4 to prevent the standard wheelset 5 from colliding with the scanning component 4 when rotating. The control structure controls the operation of the first motor 63, and drives the turbine through the worm of the worm assembly 62, so that the turbine assembly 65 rotates in the turbine bracket 64, and further drives the connecting disk 67 connected thereto to rotate, so that the bracket body 69 rotates, and drives the standard wheelset 5 to rotate a predetermined angle. According to actual conditions, the predetermined angle can be 90°, or an angle close to 90°, so that the first wheel 50 and the second wheel 51 are located directly above the two second support structures 7 after rotation.

[0113] Step S12: Control the two second support structures to rise simultaneously in the height direction until the support wheel and the drive wheel are in contact with the first wheel and the second wheel respectively, and further rise to lift the standard wheelset off the first support structure.

[0114] Specifically, refer to Fig.10The control structure controls the lifting assembly 73 to lift up the support frame 72, so that the support wheel 71 and the driving wheel 74 are simultaneously lifted up and contact the first wheel 50 and the second wheel 51. The lifting assembly 73 continues to lift up, so that the axle 52 is separated from the fork of the bracket body 69. At this time, the standard wheelset 5 is supported by the support wheels 71 and the driving wheels 74 of the two second support structures 7.

[0115] Step S13: Control the scanning component to scan the geometric parameters of the remaining parts of the standard wheelset.

[0116] The scanning component 4 is further used to scan the geometric parameters of the area of ​​the standard wheelset 5, and the geometric parameters of the remaining parts include: the inner distance of the wheelset, the distance between the brake discs, the thickness of the brake discs and the diameter of the brake discs. The control structure controls the moving component 1 to adjust the position of the scanning component 4 to further improve the accuracy of the measurement. The detection method uses a detection device to detect the standard wheelset 5, and obtains the scanning parameters for processing, which reduces the error caused by manual measurement and provides more accurate and reliable data for subsequent value traceability, wheelset structure analysis, accuracy degradation analysis, wheelset service life prediction and determination of wheelset uncertainty level. For example, when the scanning area of ​​the scanning component 4 cannot cover the area to be measured of the standard wheelset 5 at this time, such as the axle 52 and the brake disc 53, the linear feed mechanism is adjusted to move the scanning component 4 forward, or the vertical moving structure 11 is adjusted to move the scanning component 4 downward, combined with the adjustment of the mechanical arm 3, the scanning component 4 is finally brought close to the standard wheelset 5.

[0117] The scanning of the rest of the standard wheelset 5 is still achieved by the mechanical arm 3 driving the scanning assembly 4 to swing around the center of the rotation circle, and the data coordinates obtained by scanning are recorded with the center of the rotation circle as the reference. For example, when the scanning assembly 4 swings close to the first wheel 50, the first wheel 50 and the brake disc 53 on the side close to the first wheel 50 fall into the scanning area of ​​the scanning assembly 4. When the scanning assembly 4 swings close to the second wheel 51, the second wheel 51 and the brake disc 53 on the side close to the second wheel 51 fall into the scanning area of ​​the scanning assembly 4. Based on the coordinates of the center of the rotation circle and the swing radius during the swing, the wheelset inner side distance, brake disc spacing, brake disc thickness and brake disc diameter of the standard wheelset can be calculated.

[0118] At the same time, in order to obtain more accurate data, the standard wheelset 5 can be rotated to perform multiple scans on different positions along the circumference of the standard wheelset 5, and the accuracy of the measurement can be improved by calculating the average value or tolerance.

[0119] The control structure controls the operation of the second motor 76, drives the synchronous belt 75 to rotate through the first synchronous pulley 77, and drives the second synchronous pulley 78 to rotate. The second synchronous pulley 78 rotates synchronously with the driving wheel 74, so that the second motor 76 drives the driving wheel 74. The driving wheel 74 further drives the standard wheel set 5 to rotate around the axis of the axle 52. Since two second support structures 7 are provided, the two driving wheels 74 rotate synchronously for the first wheel 50 and the second wheel 51, thereby driving the standard wheel set 5 as a whole. According to the position to be scanned in actual conditions, the standard wheel set 5 can be rotated multiple times for scanning, or the standard wheel set 5 can be rotated to a state where multiple detection positions can be obtained at the same time, so as to reduce the error accumulation caused by the multiple rotations of the standard wheel set 5.

[0120] Step S14: Compare the geometric parameters with the theoretical geometric parameters of the standard wheelset to determine the accuracy level of the standard wheelset, where the accuracy level represents the geometric parameter status of the standard wheelset.

[0121] After completing the measurement of the geometric parameters of the standard wheelset 5, the control structure calculates the geometric parameters of the standard wheelset 5 and performs the next step of processing. For example, the geometric parameters are compared with the theoretical geometric parameters of the standard wheelset 5 to evaluate the accuracy level of the standard wheelset 5; the geometric parameters are compared with the wheelset at different use stages to obtain the accuracy degradation law and service life change trend of the standard wheelset 5, and then a comparative analysis is performed based on this, and the quality monitoring of the wheelset is realized in combination with the accuracy level.

[0122] When the control structure detects that the accuracy level of the measured values ​​of the geometric parameters of the standard wheelset 5 has changed significantly, or when there is doubt about the measured data of the geometric parameters of the standard wheelset 5, the measurement process such as steps S1-S13 is repeated to improve the accuracy and efficiency of the scan. At the same time, based on the measured geometric parameter data of the standard wheelset 5 during different cycles, a full life analysis of the standard wheelset 5 is performed. According to the influence of the standard wheelset 5 on the traceability of the standard wheelset value under different conditions, a reference value is set to evaluate whether the standard wheelset 5 needs to be repaired or replaced. When the measured values ​​of the geometric parameters of the standard wheelset 5 exceed the set reference value, the user is reminded to repair or replace the standard wheelset 5 to ensure the accuracy of the traceability of the standard wheelset value.

[0123] Step S15: storing geometric parameters and accuracy levels.

[0124] The processed geometric parameters are stored and the calculated geometric parameters are uploaded to the vehicle depot data management center to form a geometric parameter database of the standard wheelset 5, providing a basic database for subsequent lathe benchmark calibration.
