Abstract
Description
Technical Field
[0001] This invention relates to the field of contact measurement technology, and specifically to a guide-type self-aligning and tilting auxiliary method and system for engine rotating bodies. Background Technology
[0002] When measuring the rotating body of an engine, since the surface of the measuring equipment cannot be perfectly parallel to the ground plane, the reference plane of the measuring equipment cannot be perfectly parallel to the ground plane when it is placed on the measuring equipment. Therefore, a self-aligning table with adjustable tilt angle and axis is required. The rotating body is placed on the self-aligning table, and the tilt angle and axis of the self-aligning table are adjusted so that the reference plane of the rotating body is parallel to the ground plane and the axis coincides with the center of rotation. Usually, when the workpiece uses the common axis of two cross sections as a reference, the upper and lower cross sections of the workpiece need to be aligned concentrically and parallel to the ground. Existing technology generally relies on the operator's visual judgment of the inductance meter pointer display or observation of the probe's fluctuation curve, without the aid of software tools, to judge the adjustment amount of each knob on the self-aligning table based on experience, until the inductance meter pointer fluctuation is less than 2 micrometers, at which point the self-alignment is complete.
[0003] Because the traditional self-alignment and tilting methods relied entirely on human visual judgment, operators needed to monitor the probe's readings during rotation and adjust the angle of the self-aligning platform to ensure the probe's runout was below a certain value. This process was highly dependent on the operator's experience, and for operators without the necessary skills, completing the self-alignment and tilting adjustments was extremely time-consuming.
[0004] Therefore, the inventors provide a guide-type self-aligning and tilting auxiliary method and system for engine rotating bodies. Summary of the Invention
[0005] (1) Technical problems to be solved
[0006] This invention provides a guided self-alignment and tilting auxiliary method and system for engine slewing bodies, solving the technical problem that the adjustment process of traditional self-alignment and tilting methods is time-consuming.
[0007] (2) Technical solution
[0008] This invention provides a guided self-aligning and tilting auxiliary method for an engine rotating body, comprising the following steps:
[0009] Based on the inductance measurements of the upper and lower reference cylinders within a 360° range, the first eccentricity, first eccentricity angle, second eccentricity, and second eccentricity angle of the two reference cylinders are calculated respectively.
[0010] Based on the first eccentricity angle, the first eccentricity is decomposed into a first offset and a second offset along the two vertical directions X and Y. Based on the second eccentricity angle, the second eccentricity is decomposed into a third offset and a fourth offset along the two vertical directions X and Y. The first relative eccentricity and the first relative eccentricity angle of the upper reference cylinder relative to the lower reference cylinder are determined.
[0011] Based on the first relative eccentricity angle and the height difference between the upper reference cylinder and the lower reference cylinder, calculate the inclination angle between the upper reference cylinder and the lower reference cylinder;
[0012] Based on the tilt angle, the height of the lower reference cylinder to the plane of the self-aligning table, and the height of the self-aligning platform to the center of the self-aligning table, calculate the second relative eccentricity of the lower reference cylinder relative to the center of the axis.
[0013] Based on the first relative eccentricity angle, the second relative eccentricity, the first offset, and the second offset, the adjustment amounts corresponding to the four directions X, Y, A, and B of the centering table are determined respectively;
[0014] Four remaining offsets are calculated based on the difference between the inductance meter reading and the adjustment amount, and the four remaining offsets are adjusted to zero in sequence.
[0015] Further, the step of decomposing the first eccentricity into a first offset and a second offset along the two perpendicular directions X and Y based on the first eccentricity angle, and decomposing the second eccentricity into a third offset and a fourth offset along the two perpendicular directions X and Y based on the second eccentricity angle, to determine the first relative eccentricity and the first relative eccentricity angle of the upper reference cylinder relative to the lower reference cylinder, specifically includes the following steps:
[0016] Based on the first eccentricity angle and the second eccentricity angle, the first eccentricity and the second eccentricity are respectively decomposed into the first offset, the second offset, the third offset and the fourth offset in the X and Y directions;
[0017] The first relative eccentricity is determined based on the first difference between the first offset and the third offset, and the second difference between the second offset and the fourth offset.
[0018] The first relative eccentricity angle is determined based on the first relative eccentricity, the first difference, or the second difference.
[0019] Furthermore, the calculation formulas for the adjustment amounts corresponding to the four directions X, Y, A, and B of the self-aligning table are as follows:
[0020]
[0021] In the formula, g1-x For the first offset, g 1-y λ is the second offset, λ is the first relative eccentricity, and p 1o This is the second relative eccentricity.
[0022] Further, the step of calculating four remaining offsets based on the difference between the inductance meter reading and the adjustment amount, and sequentially adjusting the four remaining offsets to zero, specifically includes the following steps:
[0023] The first offset, the second offset, the third offset, and the fourth offset are respectively determined as the adjustment amounts in the four directions of X, Y, A, and B;
[0024] Four remaining offsets are calculated based on the difference between the value of the inductance meter and the corresponding adjustment amount.
[0025] The four adjustment values are dynamically adjusted sequentially until the corresponding four remaining offset values are all zero.
[0026] Furthermore, the step of dynamically adjusting the four adjustment amounts sequentially until the corresponding four remaining offsets are all zero specifically involves:
[0027] When the knob is placed in the designated position and "Start Adjustment" is clicked, the reading value of the inductance meter at that moment is recorded. When the change in the reading value is the same as the adjustment amount, the adjustment is complete.
[0028] Furthermore, the designated position is directly below the position of the inductance meter probe.
[0029] Furthermore, the step of calculating the first eccentricity, first eccentricity angle, second eccentricity, and second eccentricity angle of the two reference cylinders based on the measurement data of the inductance meters of the upper and lower reference cylinders within a 360° range specifically includes the following steps:
[0030] Rotate knob A of the centering and tilting stage directly below the inductance meter and confirm that the position is 0°.
[0031] Rotate the self-aligning and tilting stage to collect measurement data of the upper and lower reference cylindrical surfaces within a 360° range;
[0032] After the data collection is completed, the corresponding first eccentricity, first eccentricity angle, second eccentricity, and second eccentricity angle are calculated.
[0033] The present invention also provides a guide-type self-aligning and tilting auxiliary system for an engine rotating body, comprising:
[0034] The first calculation unit is used to calculate the first eccentricity, the first eccentricity angle, the second eccentricity, and the second eccentricity angle of the two reference cylinders based on the measurement data of the inductance meters of the upper and lower reference cylinders within a 360° range.
[0035] The decomposition unit is used to decompose the first eccentricity into a first offset and a second offset along the two vertical directions X and Y based on the first eccentricity angle, and to decompose the second eccentricity into a third offset and a fourth offset along the two vertical directions X and Y based on the second eccentricity angle, thereby determining the first relative eccentricity and the first relative eccentricity angle of the upper reference cylinder relative to the lower reference cylinder.
[0036] The second calculation unit is used to calculate the inclination angle between the upper reference cylinder and the lower reference cylinder based on the first relative eccentricity angle and the height difference between the upper reference cylinder and the lower reference cylinder.
[0037] The third calculation unit is used to calculate the second relative eccentricity of the lower reference cylinder relative to the axis based on the tilt angle, the height of the lower reference cylinder to the plane of the self-aligning table and the height of the self-aligning platform to the self-aligning table adjustment axis.
[0038] The determining unit is used to determine the adjustment amount corresponding to the four directions X, Y, A, and B of the centering table based on the first relative eccentricity angle, the second relative eccentricity, the first offset, and the second offset, respectively.

[0055] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0057] Figure 1 This is a flowchart illustrating a guided self-aligning and tilting auxiliary method for an engine rotating body provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the method may include the following steps:
[0058] S100. Based on the measurement data of the inductance meters of the upper and lower reference cylinders within a 360° range, calculate the first eccentricity, the first eccentricity angle, the second eccentricity, and the second eccentricity angle of the two reference cylinders respectively.
[0059] S200. Based on the first eccentricity angle, the first eccentricity is decomposed into the first offset and the second offset along the two vertical directions of X and Y. Based on the second eccentricity angle, the second eccentricity is decomposed into the third offset and the fourth offset along the two vertical directions of X and Y. The first relative eccentricity and the first relative eccentricity angle of the upper reference cylinder relative to the lower reference cylinder are determined.
[0060] S300. Based on the first relative eccentricity angle and the height difference between the upper and lower reference cylinders, calculate the inclination angle between the upper and lower reference cylinders.
[0061] S400. Based on the inclination angle, the height of the lower reference cylinder from the self-aligning table plane and the height of the self-aligning platform from the self-aligning table adjustment axis, calculate the second relative eccentricity of the lower reference cylinder relative to the axis.
[0062] S500. Based on the first relative eccentricity angle, the second relative eccentricity, the first offset, and the second offset, determine the adjustment amounts corresponding to the four directions X, Y, A, and B of the centering table respectively.
[0063] S600. Calculate four remaining offsets based on the difference between the inductance meter reading and the adjustment amount, and adjust the four remaining offsets to zero in sequence.
[0064] In the above embodiments, such as Figure 2 As shown, the four directions X, Y, A, and B are all located on the same horizontal plane, and the included angle between any two adjacent directions is 90°.
[0065] like Figure 3As shown, the second inductance meter 2 and the first inductance meter 1 are placed on the two reference cylindrical positions, one above the other. Based on the measurement data of the upper and lower reference cylindrical positions within a 360-degree range, the eccentricity of the two cross sections is calculated. The first eccentricity of the lower cross section is g1, and the first eccentricity angle is α1. The second eccentricity of the upper cross section is g2, and the second eccentricity angle is α2.
[0066] The calculated adjustment amount is displayed on the software interface. When the user adjusts the knob, the software interface calculates the remaining offset based on the difference between the change in the inductance meter value and the adjustment amount, and prompts the user through the software interface to adjust the remaining offset to "0.000".
[0067] By utilizing software algorithms, operators can quickly, intuitively, and accurately complete centering and tilting adjustments, requiring only a few iterations (the workpiece rotates completely several cycles, usually within five times), which is relatively time-efficient.
[0068] As an optional implementation, step S200 specifically includes the following steps:
[0069] S201. Based on the first eccentricity angle and the second eccentricity angle, the first eccentricity and the second eccentricity are decomposed into the first offset, the second offset, the third offset and the fourth offset in the X and Y directions, respectively.
[0070] S202. Determine the first relative eccentricity based on the first difference between the first offset and the third offset and the second difference between the second offset and the fourth offset;
[0071] S203. Determine the first relative eccentricity angle based on the first relative eccentricity, the first difference, or the second difference.
[0072] Specifically, the two eccentricities of the upper and lower sections are decomposed into offsets g in the X and Y directions based on the eccentricity and eccentricity angle, respectively. 1-x g 1-y g 2-x g 2-y The formula for calculating the offset after decomposition is as follows:
[0073]
[0074] The differences between the upper and lower sections in the X and Y directions are p, respectively. x =g 2-x -g 1-x p y =g 2-y -g 1-y The coaxiality of the two cross sections, that is, the first relative eccentricity of the upper cross section relative to the lower cross section, is: The first relative eccentricity angle is
[0075] The angle formed by the line connecting the two eccentric cylindrical surfaces in space and the vertical axis is the inclination angle. Let the height difference between the upper and lower sections be d. 12 The formula for calculating the tilt angle is as follows:
[0076]
[0077] Calculate the distance between the eccentricity of the lower section and the axis proportionally, and let the height of the lower section from the self-aligning table plane be d. 1t The height of the self-aligning platform from the self-aligning table to the center of the shaft is d. to The formula for calculating the eccentricity of the lower section relative to the axis, i.e., the eccentricity of the lower section relative to the axis, is as follows:
[0078] p 1o =tanθ×(d 1t -d to ).
[0079] As an optional implementation method, the calculation formulas for the adjustment amounts corresponding to the four directions X, Y, A, and B of the self-aligning table are as follows:
[0080]
[0081] In the formula, g 1-x For the first offset, g 1-y The second offset is λ, the first relative eccentricity is p. 1o This is the second relative eccentricity.
[0082] As an optional implementation, step S400 specifically includes the following steps:
[0083] S401. Determine the first offset, second offset, third offset, and fourth offset as the corresponding adjustment amounts in the four directions of X, Y, A, and B, respectively.
[0084] S402. Calculate the four remaining offsets based on the difference between the inductance meter reading and the corresponding adjustment amount.
[0085] S403. Dynamically adjust the four adjustment values sequentially until the corresponding four remaining offset values are all zero.
[0086] As an optional implementation method, step S403 specifically involves: when the knob is placed in the designated position and "Start Adjustment" is clicked, the reading value of the inductance meter at that moment is recorded; when the change in the reading value is the same as the adjustment amount, the adjustment is completed.
[0087] Specifically, the method for dynamically prompting the user to adjust the value to "0.000" is as follows: When the user places the knob in the designated position and clicks "Start Adjustment," the software immediately records the inductance meter reading at that moment and correlates it with the knob's adjustment value. Whenever the inductance meter reading changes by a certain value (e.g., 0.1), the adjustment value also dynamically changes by 0.1. Thus, when the inductance meter reading changes to match the adjustment value, the user has adjusted the value to "0.000," completing the adjustment.
[0088] As an optional implementation, the designated position is directly below the inductance meter probe.
[0089] Specifically, Figure 3 The X knob can be adjusted at the indicated position, thus achieving a one-to-one correspondence between the adjustment amount and the probe reading in terms of magnitude.
[0090] As an optional implementation, step S100 specifically includes the following steps:
[0091] S101. Rotate the A knob of the centering and tilting stage to the position directly below the inductance meter, and confirm that the position is 0°.
[0092] S102, Rotary self-aligning and tilting stage, to collect measurement data of the upper and lower reference cylindrical surfaces within a 360° range;
[0093] S103. After the data acquisition is completed, calculate the corresponding first eccentricity, first eccentricity angle, second eccentricity and second eccentricity angle.

The determining unit is used to determine the adjustment amount corresponding to the four directions X, Y, A, and B of the centering table based on the first relative eccentricity angle, the second relative eccentricity, the first offset, and the second offset, respectively. The adjustment unit is used to calculate four remaining offsets based on the difference between the reading of the inductance meter and the adjustment amount, and to adjust the four remaining offsets to zero in sequence.
