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 will also not 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 needed. 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. Typically, the self-aligning and tilting method involves placing two contact probes on the reference end face and the reference cylindrical surface respectively, and rotating the self-aligning table. When the probe runout is within a certain range (usually about 2 micrometers), the measurement requirements are considered met, and the self-aligning is completed.

[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 measurement data of the inductance meters of the reference end face and the reference cylinder within a 360° range, calculate the eccentricity and eccentricity angle of the reference cylinder, and the tilt and tilt angle of the reference end face.

[0010] Based on the eccentricity angle, the eccentricity is decomposed into a first offset and a second offset in the two vertical directions X and Y. Based on the tilt angle, the tilt is decomposed into a third offset and a fourth offset in the two vertical directions A and B. Among them, 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°.

[0011] Based on the difference between the inductance meter reading and the corresponding offset, four remaining offsets are calculated, and the four remaining offsets are adjusted to zero in sequence.

[0012] Furthermore, the step of decomposing the eccentricity into first and second offsets in the X and Y vertical directions based on the eccentricity angle, and decomposing the tilt into third and fourth offsets in the A and B vertical directions based on the tilt angle, specifically involves:

[0013] Based on the eccentricity angle α, the eccentricity g1 of the reference cylinder is decomposed into the first offset g in the X and Y directions. 1-x Second offset g 1-y Based on the tilt angle β, the tilt amount g2 of the reference end face is decomposed into a third offset amount g in the A and B directions. 2-a Fourth offset g 2-b ;

[0014] The formula for calculating the offset after decomposition is as follows:

[0015]

[0016] Further, the step of calculating four remaining offsets based on the difference between the inductance meter reading and the corresponding offset, and then sequentially adjusting the four remaining offsets to zero, specifically includes the following steps:

[0017] 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;

[0018] Four remaining offsets are calculated based on the difference between the value of the inductance meter and the corresponding adjustment amount.

[0019] The four adjustment values ​​are dynamically adjusted sequentially until the corresponding four remaining offset values ​​are all zero.

[0020] Furthermore, the step of dynamically adjusting the four adjustment amounts sequentially until the corresponding four remaining offsets are all zero specifically involves:

[0021] 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.

[0022] Furthermore, the designated position is directly below the position of the inductance meter probe.

[0023] Furthermore, the step of calculating the eccentricity and eccentricity angle of the reference cylinder, and the tilt and tilt angle of the reference end face, based on the measurement data of the inductance meters of the reference end face and the reference cylinder within a 360° range, specifically includes the following steps:

[0024] Rotate knob A of the centering and tilting stage directly below the inductance meter and confirm that the position is 0°.

[0025] A rotating self-aligning and tilting stage is used to collect measurement data of the reference cylindrical surface and the reference end face within a 360° range;

[0026] After the data collection is completed, the corresponding eccentricity, eccentricity angle, tilt amount, and tilt angle are calculated.

[0027] The present invention also provides a guide-type self-aligning and tilting auxiliary system for an engine rotating body, comprising:

[0028] The calculation unit is used to calculate the eccentricity and eccentricity angle of the reference cylinder, and the tilt and tilt angle of the reference end face, based on the measurement data of the inductance meters of the reference end face and the reference cylinder within a 360° range.

[0029] The decomposition unit is used to decompose the eccentricity into a first offset and a second offset in two vertical directions, X and Y, based on the eccentricity angle, and to decompose the tilt into a third offset and a fourth offset in two vertical directions, A and B, based on the tilt angle; wherein 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°.

[0030] The adjustment unit is used to calculate four remaining offsets based on the difference between the reading of the inductance meter and the corresponding offset, and to adjust the four remaining offsets to zero in sequence.

[0031] Furthermore, the adjustment unit specifically includes:

[0032] A subunit is defined to determine the first offset, the second offset, the third offset, and the fourth offset as the adjustment amounts in the four directions of X, Y, A, and B, respectively.

[0033] The calculation subunit is used to calculate four remaining offsets based on the difference between the value of the inductance meter and the corresponding adjustment amount.

[0034] The adjustment subunit is used to dynamically adjust the four adjustment values ​​sequentially until the corresponding four remaining offsets are all zero.

[0035] The present invention also provides an electronic device, including a processor, a memory, and a bus, wherein:

[0036] The processor and the memory communicate with each other via the bus;

[0037] The processor can invoke a computer program in the memory to perform the steps of the above method.

[0038] The present invention also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the above-described method.

[0052] 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:

[0053] S100. Based on the measurement data of the inductance meters of the reference end face and the reference cylinder within a 360° range, calculate the eccentricity and eccentricity angle of the reference cylinder, and the tilt and tilt angle of the reference end face.

[0054] S200. Based on the eccentricity angle, the eccentricity is decomposed into first and second offsets in the X and Y vertical directions; based on the tilt angle, the tilt is decomposed into third and fourth offsets in the A and B vertical directions; where, for example... Figure 2 As shown, the four directions X, Y, A, and B are all located on the same horizontal plane, and the angle between any two adjacent directions is 90°.

[0055] S300. Calculate the four remaining offsets based on the difference between the inductance meter reading and the corresponding offset, and adjust the four remaining offsets to zero in sequence.

[0056] In the above implementation, 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 offset amount, and prompts the user through the software interface to adjust the remaining offset amount to "0.000".

[0057] 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.

[0058] As an optional implementation, step S100 specifically includes:

[0065] S403. Dynamically adjust the four adjustment values ​​sequentially until the corresponding four remaining offset values ​​are all zero.

[0066] Specifically, calculate the offset that the four knobs on the self-aligning platform—the self-aligning knobs (X, Y) and the tilt knobs (A, B)—should be adjusted, and display the offset on the software interface, as shown below:

[0067]

[0068] 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.

[0069] Specifically, the designated location is directly below the position of the inductance meter probe. Figure 3 The X knob can be adjusted at the indicated position. This allows for a one-to-one correspondence between the adjustment amount and the probe reading in terms of magnitude. The first inductance meter 1 and the second inductance meter are used to detect the corresponding reference cylinder and reference end face, respectively.

[0070] As an optional implementation, step S100 specifically includes the following steps:
