BRIEF DESCRIPTION OF DRAWINGS

[0030] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, the drawings needed to be used in the embodiments or the prior art description will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present application, and other drawings can also be obtained by those skilled in the art without creative labor.

[0031] Figure 1 The flowchart of the electrical unroundness correction method of the cylindrical component provided by the embodiments of the present application is shown.

[0032] Figure 2 The structure block diagram of the electrical unroundness correction device of the cylindrical component provided by the embodiments of the present application is shown. DETAILED DESCRIPTION

[0033] For the rotor and other shaft-like components, the electrical unroundness is generally caused by two factors. On the one hand, the surface smoothness of the shaft-like component is insufficient, and there is mechanical runout, so that the uniformity of the electromagnetic characteristics of each different position on the surface of the shaft-like component is relatively poor. In addition, the material of the shaft-like component is not necessarily isotropic and uniform in density, which also leads to the problem that even if the surface of the shaft-like component does not have mechanical runout, the electrical unroundness of the surface is still unqualified, which increases the difficulty of the electrical unroundness correction of the shaft-like component to a certain extent.

[0034] In the traditional process of electrical unroundness correction of the shaft-like component, the electrical unroundness of each point on the surface of the shaft-like component is measured, and the points are polished according to the measurement results. The whole correction process is relatively complicated, and the correction effect is often not ideal.

[0035] Therefore, the present application provides a kind of component overall electrical unroundness automatic correction, reduce the difficulty of correction, improve correction effect.

[0036] For the person skilled in the art to better understand the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] As shown in Figure 1 , Figure 1 The flowchart of the electrical out-of-roundness correction method of the cylindrical component provided in the embodiments of the present application is shown. In the specific embodiments of the present application, the electrical out-of-roundness correction method of the cylindrical component can include:

[0038] S11: Collecting radius data of each position point on the outer surface of the cylindrical component to be corrected by using an eddy current displacement sensor.

[0039] It should be noted that the eddy current displacement sensor detects the radius data of the cylindrical component to be corrected based on the principle of electromagnetic induction to make the sensor produce eddy current effect, thereby detecting the induced voltage generated by each position point on the surface of the cylindrical component to be corrected, and converting the induced voltage to obtain the radius data. When the eddy current displacement sensor detects different positions on the surface of the cylindrical component to be corrected, the size of the detected induced voltage will fluctuate with the size of the radius of the measured point, so that the radius data of the measured position point can be obtained based on the conversion of the induced voltage measured by the eddy current displacement sensor.

[0040] However, since the eddy current displacement sensor measures the cylindrical component to be corrected according to the eddy current effect generated by electromagnetic induction, not only the radius of the measured point, but also the electromagnetic characteristics of the cylindrical component to be corrected affect the eddy current effect. As can be seen, the out-of-roundness condition reflected by the radius data detected by the eddy current displacement sensor is not only caused by the mechanical jumping of the cylindrical component to be corrected, but also caused by the electromagnetic characteristics, that is, even if there is no mechanical jumping at a certain position point, the radius data detected at this point may still show the problem of out-of-roundness.

[0041] Therefore, the radius data of the cylindrical component to be corrected detected by the eddy current displacement sensor in the present application is not the out-of-roundness in the conventional sense of mechanical size, but the electrical equivalent radius data representing the electromagnetic characteristics determined by the mechanical out-of-roundness and the unevenness of the material electromagnetic characteristics of the cylindrical component to be corrected. Subsequently, using the radius data as the data basis for correcting the cylindrical component to be corrected can effectively ensure the reliability of the data.

[0042] S12: Determining the radius correction amount of each position point on the outer surface of the cylindrical component to be corrected according to the radius data and the first standard radius data.

[0043] The radius data of the to-be-corrected cylindrical part in the embodiment should normally fluctuate within a standard radius data interval. The maximum value of the standard radius data interval is set as a first standard radius data, and the minimum value of the standard radius data interval is set as a second standard radius data. When the radius data is greater than the first standard radius data, it indicates that the position point corresponding to the radius data is at a peak position point of the electrical out-of-roundness fluctuation. When the radius data is less than the second standard radius data, it indicates that the position point corresponding to the radius data is at a trough position point of the electrical out-of-roundness fluctuation.

[0044] Optionally, the process of determining the radius correction amount for the peak position point on the to-be-corrected cylindrical part can include:

[0045] According to the radius data and the first standard radius data, it is determined that the radius correction amount of each position point on the outer surface of the to-be-corrected cylindrical part satisfies wherein a1 is the first standard radius data, and b is the radius data.

[0046] It should be noted that the first standard radius data in the embodiment is a standard for judging the peak position point on the to-be-corrected cylindrical part. When the radius data of a position point on the to-be-corrected cylindrical part is less than or equal to the first standard radius data, it can be considered that the radius of the position point is not too large and does not need to be corrected. When the radius of the position point is greater than the first standard radius data, the deviation value b-a1 that the radius data exceeds the first standard radius data.

[0047] It can be understood that the radius correction amount for the to-be-corrected cylindrical part in the embodiment is a correction amount for trimming the mechanical physical size of the to-be-corrected cylindrical part, that is, the mechanical radius of the to-be-corrected cylindrical part is reduced by the radius correction amount. However, as described above, the electrical out-of-roundness on the surface of the to-be-corrected cylindrical part can not be caused by mechanical structural unevenness, but can be caused by uneven electromagnetic properties of the material. In addition, the mechanical runout deviation of the to-be-corrected cylindrical part that has been polished and extruded has been controlled to be within 0.002 mm. Therefore, only correcting the position point with the measured radius data that is too large by the deviation amount b-a1 can not guarantee to eliminate the problem of electrical out-of-roundness caused by uneven electromagnetic properties. Therefore, in order to ensure the effect of correcting the radius data greater than the first standard radius data, the double deviation value can be used as the radius correction amount, that is, the corrected radius is still smaller than the first standard radius data by b-a1. That is, 2b-2a1 is used as the radius correction amount to correct the to-be-corrected cylindrical part.

[0048] In another optional embodiment of the present application, the process of determining the radius correction amount of each position point on the outer surface of the to-be-corrected cylindrical part can include:

[0049] The three-dimensional model of the to-be-repaired cylinder is created according to the radius data of each position point on the outer surface of the to-be-repaired cylindrical part.

[0050] The standard three-dimensional model is created according to the radius data of each position point on the outer surface of the to-be-repaired cylindrical part and the first standard radius data, and the radius satisfies , wherein a1 is the first standard radius data, and b is the radius data.

[0051] The three-dimensional model and the standard three-dimensional model are compared to determine the radius correction amount of each position point on the to-be-repaired cylindrical part.

[0052] It can be understood that for the position point on the to-be-repaired cylindrical part whose radius data is less than or equal to the first standard radius data, the radius in the three-dimensional model and the standard three-dimensional model is equal, and thus the radius correction amount of the corresponding position point is 0. Only the position point on the to-be-repaired cylindrical part whose radius data is greater than the first standard radius data has a corresponding non-zero radius correction amount.

[0053] In this embodiment, the three-dimensional model of the to-be-repaired cylinder and the standard three-dimensional model are established in a three-dimensional modeling manner, wherein the standard three-dimensional model is a structure model required to be corrected and formed by the to-be-repaired cylinder.

[0054] In the actual correction process of the to-be-repaired cylindrical part, the comparison difference of each surface position point between the three-dimensional model of the to-be-repaired cylinder and the standard three-dimensional model can be used to determine the radius correction amount of each position, and then the to-be-repaired cylindrical part is corrected according to each position point on the surface thereof. Similarly to the above embodiment, the radius correction amount of each position point whose radius data exceeds the first standard radius data is 2b-2a1.

[0055] S13: According to the radius correction amount, the ball cutter is controlled to correct and polish the to-be-repaired cylinder.

[0056] After the radius correction amount of the to-be-repaired cylindrical part is determined, the ball cutter can be controlled to polish the to-be-repaired cylindrical part according to the radius correction amount, and the to-be-repaired cylindrical part can be corrected.

[0057] Based on the above embodiment, the peak position point of the first standard radius data greater than the radius data of the to-be-corrected cylinder is corrected, that is, the peak position of the electrical roundness fluctuation of the to-be-corrected cylinder is corrected, and the valley position point of the electrical roundness fluctuation of the to-be-corrected cylinder also needs to be corrected. Therefore, in another optional embodiment of the present application, after the radius data of each position point on the outer surface of the to-be-corrected cylindrical part is collected by using the eddy current displacement sensor, before the radius correction amount of each position point on the outer surface of the to-be-corrected cylindrical part is determined according to the radius data and the first standard radius data, the following steps are further included:

[0058] The position point of the second standard radius data less than the radius data on the outer surface of the to-be-corrected cylindrical part is polished along the axis direction of the to-be-corrected cylindrical part, wherein the first standard radius data is greater than the second standard radius data.

[0059] As described above, the second standard radius data is a standard for judging whether the position point on the to-be-corrected cylindrical part is a valley position point. When the radius data corresponding to the position point on the to-be-corrected cylindrical part is less than or equal to the second standard radius data, it can be determined that the position point is a valley position point.

[0060] During the process of correcting the valley position of the electrical roundness fluctuation of the to-be-corrected cylindrical part, the roughness of the surface of the part can be damaged along the axial direction by using sandpaper, scouring cloth and the like, so as to improve the electrical roundness of the valley. Of course, in order to realize the automatic correction of the to-be-corrected cylindrical part, the to-be-corrected cylindrical part can be polished by using a grinding wheel driven by a lathe, so as to correct the valley position point of the electrical roundness fluctuation of the to-be-corrected cylindrical part.

[0061] As described above, in the process of correcting the electrical roundness of the cylindrical part in the present application, the radius data of each position point on the surface of the to-be-corrected cylindrical part is detected by using the eddy current displacement sensor. The eddy current displacement sensor is a sensor based on electromagnetic induction principle to generate eddy current effect, and the measured radius data is influenced by the electromagnetic characteristics of the to-be-corrected cylindrical part. Therefore, the measured radius data can be used as the data for correcting the electrical roundness of the surface of the to-be-corrected cylindrical part, which can ensure the accuracy of the correction result to a certain extent. On this basis, the surface of the to-be-corrected cylindrical part is automatically corrected by using the ball cutter driven by the measured radius data, which reduces the workload of manual operation and is beneficial to improving the correction effect.

The cylindrical part electrical roundness correction device described below can be correspondingly referred to the cylindrical part electrical roundness correction method described above.
