Description

Technical Field

[0001] This invention relates to the field of honing wheel diagnostic technology, and specifically to a honing wheel diagnostic method and system. Background Technology

[0002] Honing is a commonly used precision machining method in machining, mainly used to improve the dimensional accuracy, shape accuracy, and surface quality of the inner holes of workpieces. The honing wheel, as a key tool in honing, directly affects the machining quality and efficiency through its performance and condition.

[0003] Currently, the replacement of honing wheels mainly relies on manual disassembly and judgment based on experience to determine whether replacement is necessary.

[0004] This traditional method of judgment has the following problems:

[0005] 1. Manual judgment is inefficient. To determine the wear condition of the honing wheel, it is necessary to frequently disassemble the honing wheel for inspection, which not only consumes a lot of time and manpower, but also leads to production interruptions and reduces production efficiency.

[0006] 2. The accuracy of manual judgment relies on personal experience. Different operators may have different judgment standards, leading to significant subjectivity in the results. Moreover, it is difficult to accurately assess the wear of the honing wheel based solely on visual observation and experience, which can easily result in misjudgments.

[0007] Therefore, there is an urgent need for a honing wheel diagnostic method and system to solve the above problems. Summary of the Invention

[0011] S2. Rotate the honing wheel and collect the distance data from the origin to the surface of the honing wheel measured by the laser displacement sensor in real time;

[0012] S3. Perform data transformation and coordinate transformation on the collected distance data in sequence to obtain the two-dimensional coordinates of each point on the surface of the honing wheel;

[0013] S4. Draw the outline of the honing wheel based on the two-dimensional coordinates of each point on the surface of the honing wheel, and compare it with the outline of the standard honing wheel. If the distance between multiple points on the drawn honing wheel outline and the corresponding points on the standard honing wheel outline is greater than the set threshold, it indicates that the honing wheel is currently worn beyond the limit and needs to be replaced; otherwise, it does not need to be replaced.

[0014] Preferably, in step S1, the moving laser displacement sensor irradiates the gear at the center of the honing wheel with its laser in a manner parallel to the end face of the honing wheel, specifically including:

[0015] A laser displacement sensor is placed on one side of the honing wheel, and the laser from the laser displacement sensor is directed to illuminate the gear of the honing wheel in a manner parallel to the end face of the honing wheel. Then, the laser displacement sensor is moved in a direction that is closer to or farther away from the honing wheel, and the distance data measured by the laser displacement sensor is collected in real time. When the distance data increases abnormally, the movement is stopped. Then, the laser displacement sensor is moved half the diameter of the honing wheel to the center position of the honing wheel.

[0016] Preferably, in step S3, the collected distance data undergoes data transformation processing, specifically including:

[0017] The maximum value function is used to obtain the maximum value in the distance data, and the correction value is obtained based on the maximum value and the root circle radius. Then, the actual distance data of each point is obtained based on the correction value.

[0018] Preferably, the formula for calculating the root circle radius is:

[0019] r f =d max ±d

[0020] Where, r f Let d be the radius of the tooth root circle. max The maximum value in the distance data is d, and the correction value is d.

[0021] The formula for calculating actual distance data is:

[0022] r i =r f +|d max -d i |

[0023] Where, r i d represents the actual distance data for each point. i This refers to the distance data of each point before correction.

[0024] Preferably, in step S3, coordinate transformation is performed to obtain the two-dimensional coordinates of each point on the surface of the honing wheel, specifically including:

[0025] Based on the actual distance data r of each point i and angle θ i The two-dimensional coordinates (x, y) of each point on the surface of the honing wheel are obtained. i y i ).

[0026] Preferably, the angle θ at each point i The formula for calculation is:

[0027] θ i =ωt i

[0032] Where, x i Let y be the x-coordinate of each point on the surface of the honing wheel. i Let be the ordinate of each point on the surface of the honing wheel.

[0033] Preferably, step S3 includes the following steps before performing data conversion on the collected distance data:

[0034] The collected distance data is preprocessed using either mean filtering or median filtering.

[0035] Preferably, in step S4, the selected area of ​​multiple points on the drawn honing wheel contour map is one or more areas where the deviation between the drawn honing wheel contour map and the standard honing wheel contour map is greater than a set deviation threshold.

[0036] Preferably, in step S4, the distance D between multiple points on the drawn honing wheel profile and the corresponding points on the standard honing wheel profile is... ij The calculation formula is:

[0037]

[0038] Where, x j The x-coordinates of the corresponding points on the profile diagram of a standard honing wheel are y = x.j These are the ordinates of the corresponding points on the profile of a standard honing wheel.

[0039] A second aspect of the present invention provides a honing wheel diagnostic system applied to the honing wheel diagnostic method described above, the honing wheel diagnostic system comprising:

[0040] The positioning module is used to move the laser displacement sensor so that its laser beam is parallel to the end face of the honing wheel and shines on the gear at the center of the honing wheel, and serves as the measurement origin of the laser displacement sensor.

[0041] The data measurement and acquisition module is used to rotate the honing wheel and acquire the distance data from the origin to the surface of the honing wheel measured by the laser displacement sensor in real time.

[0042] The data processing module is used to perform data conversion and coordinate transformation on the collected distance data to obtain the two-dimensional coordinates of each point on the surface of the honing wheel;

[0043] The replacement judgment module is used to draw the outline of the honing wheel based on the two-dimensional coordinates of each point on the surface of the honing wheel, and compare it with the outline of the standard honing wheel. If the distance between multiple points on the drawn honing wheel outline and the corresponding points on the standard honing wheel outline is greater than a set threshold, it indicates that the honing wheel is currently worn beyond the limit and needs to be replaced; otherwise, it does not need to be replaced.

[0044] According to the above technical solution, based on this honing wheel diagnostic method and system, the distance data from the origin to the surface of the honing wheel measured by a laser displacement sensor is collected. Then, the collected distance data is processed by data conversion and coordinate transformation to obtain the two-dimensional coordinates of each point on the surface of the honing wheel. Then, the contour map of the honing wheel is drawn based on the obtained two-dimensional coordinates of each point on the surface of the honing wheel, and compared with the contour map of a standard honing wheel. In practical applications, based on whether the distances between multiple points on the drawn contour map of the honing wheel and the corresponding points on the contour map of the standard honing wheel are all greater than a set threshold, it can be accurately determined whether the honing wheel is worn beyond the limit and needs to be replaced. This avoids manual replacement based on experience, which would lead to premature replacement of the honing wheel and increase the cost of use, and the impact on the processing quality of the product if the honing wheel is not replaced in time.

[0045] Figure 1 This is a flowchart of the honing wheel diagnostic method;

[0046] Figure 2 This is a specific implementation method of setting up a laser displacement sensor. Detailed Implementation

[0047] The following provides a detailed description of specific embodiments of the present invention. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the present invention.

[0048] The first aspect of this invention provides a method for diagnosing honing wheels, such as... Figure 1 As shown, the honing wheel diagnostic method includes the following steps:

[0049] S1. Move the laser displacement sensor so that its laser beam is parallel to the end face of the honing wheel and shines on the gear at the center of the honing wheel, and use it as the measurement origin of the laser displacement sensor.

[0050] S2. Rotate the honing wheel and collect the distance data from the origin to the surface of the honing wheel measured by the laser displacement sensor in real time;

[0051] S3. Perform data transformation and coordinate transformation on the collected distance data in sequence to obtain the two-dimensional coordinates of each point on the surface of the honing wheel;

[0052] S4. Draw the outline of the honing wheel based on the two-dimensional coordinates of each point on the surface of the honing wheel, and compare it with the outline of the standard honing wheel. If the distance between multiple points on the drawn honing wheel outline and the corresponding points on the standard honing wheel outline is greater than the set threshold, it indicates that the honing wheel is currently worn beyond the limit and needs to be replaced; otherwise, it does not need to be replaced.

[0053] According to the above technical solution, based on this honing wheel diagnostic method, the distance data from the origin to the surface of the honing wheel measured by a laser displacement sensor is collected. Then, the collected distance data is processed by data conversion and coordinate transformation to obtain the two-dimensional coordinates of each point on the surface of the honing wheel. Then, the outline of the honing wheel is drawn based on the obtained two-dimensional coordinates of each point on the surface of the honing wheel, and compared with the outline of a standard honing wheel. In practical applications, based on whether the distances between multiple points on the drawn outline of the honing wheel and the corresponding points on the outline of the standard honing wheel are all greater than a set threshold, it can be accurately determined whether the honing wheel is worn beyond the limit and needs to be replaced. This avoids manual replacement based on experience, which would lead to premature replacement of the honing wheel and increase the cost of use, and the impact on the processing quality of the product if the honing wheel is not replaced in time. Specifically, the number of points on the honing wheel outline that are more than a set threshold away from the corresponding points on the standard honing wheel outline can be changed. This can be set according to the actual processing quality requirements of the product. Generally, the higher the processing quality of the product, the fewer points that exceed the set threshold are required.

[0054] In the honing wheel diagnostic method of the present invention, preferably, in step S1, the moving laser displacement sensor irradiates the gear at the center of the honing wheel with its laser beam parallel to the end face of the honing wheel, specifically including:

[0055] A laser displacement sensor is positioned on one side of the honing wheel, and its laser beam is directed parallel to the end face of the honing wheel onto the gears. The sensor is then moved closer to or further away from the honing wheel, and the distance data measured by the sensor is collected in real time. Movement stops when the distance data abnormally increases. The sensor is then moved half the diameter of the honing wheel to its center position. In practical applications, this allows for precise positioning of the laser displacement sensor at the center of the honing wheel, avoiding manual operation that could lead to positioning errors and affect the accuracy of subsequent diagnostics.

[0056] In one specific implementation, such as Figure 2 As shown, a slide rail perpendicular to the end face of the honing wheel is provided below the honing wheel. A slider is mounted on the slide rail, and a universal joint is mounted on the slider. The laser displacement sensor is mounted on the universal joint. In practical applications, the laser from the laser displacement sensor is first directed by the slider and the universal joint to illuminate the gears of the honing wheel in a manner parallel to the end face of the honing wheel. Then, the slider moves along the slide rail, thereby causing the laser displacement sensor to move closer to or further away from the honing wheel, thus enabling the laser displacement sensor to achieve precise positioning at the center of the honing wheel.

[0057] In the honing wheel diagnostic method of the present invention, preferably, step S3 involves data conversion processing of the collected distance data, specifically including:

[0058] The maximum value function is used to obtain the maximum value in the distance data, and the correction value is obtained based on the maximum value and the root circle radius. Then, the actual distance data of each point is obtained based on the correction value.

[0059] In one specific implementation, the formula for calculating the root circle radius is:

[0060] r f =d max ±d

[0061] Where, r f Let d be the radius of the tooth root circle. max The maximum value in the distance data is d, and the correction value is d.

[0062] The formula for calculating actual distance data is:

[0063] r i =r f+|d max -d i |

[0064] Where, r i d represents the actual distance data for each point. i This refers to the distance data of each point before correction.

[0065] In step S3, coordinate transformation is performed to obtain the two-dimensional coordinates of each point on the surface of the honing wheel, specifically including:

[0066] Based on the actual distance data r of each point i and angle θ i The two-dimensional coordinates (x, y) of each point on the surface of the honing wheel are obtained. i y i ).

[0067] In one specific implementation, the angle θ at each point i The formula for calculation is:

[0068] θ i =ωt i

[0069] Where w is the rotational speed of the honing wheel, and t i The current moment;

[0070] Two-dimensional coordinates (x, y) of each point on the surface of the honing wheel i y i The formula for calculating ) is:

[0071] x i =r i ×sinθ i

[0072] y i =r i ×cosθ i

[0073] Where, x i Let y be the x-coordinate of each point on the surface of the honing wheel. i Let be the ordinate of each point on the surface of the honing wheel.

[0074] In this invention, the two-dimensional coordinates of each point on the surface of the honing wheel are obtained by sequentially performing data conversion and coordinate transformation on the collected distance data. Then, a contour map is drawn based on the two-dimensional coordinates of each point on the surface of the honing wheel and compared with the contour map of the standard honing wheel. Compared with the method of manually judging the wear degree of the honing wheel based on experience, this method can effectively improve the accuracy of diagnosing the wear degree of the honing wheel.

[0075] In the honing wheel diagnostic method of the present invention, preferably, step S3 includes the following steps before data conversion of the collected distance data:

[0076] The collected distance data is preprocessed using mean filtering or median filtering to avoid interference from outlier data that could affect the accuracy of diagnosing the wear level of the honing wheel. Specifically, for example, if the difference between a point and its surrounding points exceeds a certain threshold among several consecutive measurement points, that point is identified as an outlier and removed or corrected.

[0077] In the honing wheel diagnosis method of the present invention, preferably, in step S4, the selected area of ​​multiple points on the drawn honing wheel contour map is one or more areas where the deviation between the drawn honing wheel contour map and the standard honing wheel contour map is greater than a set deviation threshold.

[0078] In another preferred embodiment, in step S4, the distance D between multiple points on the drawn honing wheel profile and the corresponding points on the standard honing wheel profile is... ij The calculation formula is:

[0079]

[0080] Where, x j The x-coordinates of the corresponding points on the profile diagram of a standard honing wheel are y = x. j These are the ordinates of the corresponding points on the profile of a standard honing wheel.

[0081] In one specific embodiment, the step of drawing the contour diagram of the honing wheel based on the obtained two-dimensional coordinates of each point on the surface of the honing wheel specifically includes:

[0082] Based on the two-dimensional coordinates of each point on the surface of the honing wheel, each point is displayed as a waveform icon, and the points are connected in sequence to obtain the outline of the honing wheel.

[0083] In practical applications, the first step is to compare the drawn profile of the honing wheel with that of a standard honing wheel. Then, for one or more areas in the drawing where the difference is significant (i.e., the deviation exceeds a set deviation threshold), multiple points are selected to calculate whether the distance to the corresponding point on the standard honing wheel's profile exceeds a set threshold. If the distance exceeds a threshold, the wheel needs to be replaced; otherwise, replacement is not necessary. This process ultimately achieves an accurate diagnosis of the honing wheel's wear level. Specifically, the drawing of the profile and the comparison between the drawn profile and the standard honing wheel's profile can be implemented using LabVIEW.

[0084] A second aspect of the present invention provides a honing wheel diagnostic system applied to the honing wheel diagnostic method described above, the honing wheel diagnostic system comprising:

[0085] The positioning module is used to move the laser displacement sensor so that its laser beam is parallel to the end face of the honing wheel and shines on the gear at the center of the honing wheel, and serves as the measurement origin of the laser displacement sensor.

[0086] The data measurement and acquisition module is used to rotate the honing wheel and acquire the distance data from the origin to the surface of the honing wheel measured by the laser displacement sensor in real time.

[0087] The data processing module is used to perform data conversion and coordinate transformation on the collected distance data to obtain the two-dimensional coordinates of each point on the surface of the honing wheel;

[0088] The replacement judgment module is used to draw the outline of the honing wheel based on the two-dimensional coordinates of each point on the surface of the honing wheel, and compare it with the outline of the standard honing wheel. If the distance between multiple points on the drawn honing wheel outline and the corresponding points on the standard honing wheel outline is greater than a set threshold, it indicates that the honing wheel is currently worn beyond the limit and needs to be replaced; otherwise, it does not need to be replaced.

[0089] According to the above technical solution, based on this honing wheel diagnostic system, the distance data from the origin to the surface of the honing wheel measured by the laser displacement sensor is collected. Then, the collected distance data is processed by data conversion and coordinate transformation to obtain the two-dimensional coordinates of each point on the surface of the honing wheel. Then, the contour map of the honing wheel is drawn based on the obtained two-dimensional coordinates of each point on the surface of the honing wheel, and compared with the contour map of a standard honing wheel. In practical applications, the system can accurately determine whether the honing wheel is worn beyond the limit and needs to be replaced based on whether the distances between multiple points on the drawn contour map of the honing wheel and the corresponding points on the contour map of the standard honing wheel are all greater than a set threshold. This avoids manual replacement based on experience, which could lead to premature replacement of the honing wheel and increased usage costs, or the impact on the processing quality of the product due to the honing wheel not being replaced in time.

[0090] The present invention will be described in detail below through embodiments, but the scope of protection of the present invention is not limited thereto.

[0091] Example 1

[0096] S4. Draw the outline of the honing wheel based on the two-dimensional coordinates of each point on the surface of the honing wheel, and compare it with the outline of the standard honing wheel. If the distance between multiple points on the drawn honing wheel outline and the corresponding points on the standard honing wheel outline is greater than the set threshold, it indicates that the honing wheel is currently worn beyond the limit and needs to be replaced; otherwise, it does not need to be replaced.

[0097] In step S1, the movable laser displacement sensor irradiates the gear at the center of the honing wheel with its laser beam parallel to the end face of the honing wheel. Specifically, this includes:

[0098] A laser displacement sensor is placed on one side of the honing wheel, and the laser from the laser displacement sensor is directed to illuminate the gear of the honing wheel in a manner parallel to the end face of the honing wheel. Then, the laser displacement sensor is moved in a direction that is closer to or farther away from the honing wheel, and the distance data measured by the laser displacement sensor is collected in real time. When the distance data increases abnormally, the movement is stopped. Then, the laser displacement sensor is moved half the diameter of the honing wheel to the center position of the honing wheel.

[0099] Testing has shown that the honing wheel diagnostic method described in this invention can effectively improve the accuracy of honing wheel diagnosis compared to manual diagnosis based on experience, thus enabling timely replacement of the honing wheel when its wear exceeds the limit.

[0100] Example 2

[0101] Referring to Embodiment 1, the difference is that in step S3, the collected distance data undergoes data conversion processing, specifically including:

[0102] The maximum value function is used to obtain the maximum value in the distance data, and the correction value is obtained based on the maximum value and the root circle radius. Then, the actual distance data of each point is obtained based on the correction value.

[0103] The formula for calculating the radius of the tooth root circle is:

[0104] r f =d max ±d

[0105] Where, r f Let d be the radius of the tooth root circle. max The maximum value in the distance data is d, and the correction value is d.

[0106] The formula for calculating actual distance data is:

[0107] r i =r f +|d max -d i |

[0108] Where, r i d represents the actual distance data for each point. i To correct the distance data of each point before;

[0109] In step S3, coordinate transformation is performed to obtain the two-dimensional coordinates of each point on the surface of the honing wheel, specifically including:

[0110] Based on the actual distance data r of each point i and angle θ i The two-dimensional coordinates (x, y) of each point on the surface of the honing wheel are obtained. i y i );

[0111] Angle θ at each point i The formula for calculation is:

[0112] θ i =ωt i

[0113] Where w is the rotational speed of the honing wheel, and t i The current moment;

[0114] Two-dimensional coordinates (x, y) of each point on the surface of the honing wheel i y i The formula for calculating ) is:

[0115] x i =r i ×sinθ i

[0116] y i =r i ×cosθ i

[0117] Where, x i Let y be the x-coordinate of each point on the surface of the honing wheel. i Let be the ordinate of each point on the surface of the honing wheel;

[0118] Step S3, before performing data transformation on the collected distance data, includes:

[0119] The collected distance data is preprocessed, and the preprocessing method is mean filtering;

[0120] In step S4, the distance D between multiple points on the profile drawing of the honing wheel and the corresponding points on the profile drawing of the standard honing wheel is calculated. ij The calculation formula is:

[0121]

[0122] Where, x j The x-coordinates of the corresponding points on the profile diagram of a standard honing wheel are y = x. j These are the ordinates of the corresponding points on the profile of a standard honing wheel.

[0123] Testing revealed that the honing wheel diagnostic method described in this invention, compared to the scheme in Example 1, can further improve the accuracy of diagnosing the wear degree of the honing wheel, thereby enabling timely replacement when the wear degree of the honing wheel exceeds the limit.

[0124] Example 3

[0125] The implementation follows the same procedure as Example 2, except that in step S4, the selected area of ​​multiple points on the drawn honing wheel contour map is one or more areas where the deviation between the drawn honing wheel contour map and the standard honing wheel contour map is greater than a set deviation threshold.

[0126] Testing revealed that the honing wheel diagnostic method described in this invention, compared to the scheme in Example 2, can further improve the accuracy of diagnosing the wear degree of the honing wheel, thereby enabling timely replacement when the wear degree of the honing wheel exceeds the limit.

[0127] The honing wheel diagnostic method and system provided by this invention collects distance data from the origin to the honing wheel surface measured by a laser displacement sensor. Then, the collected distance data undergoes data conversion and coordinate transformation to obtain two-dimensional coordinates of each point on the honing wheel surface. Based on these two-dimensional coordinates, a contour map of the honing wheel is drawn and compared with a standard honing wheel contour map. In practical applications, the system can accurately determine whether the honing wheel is worn beyond its limit and needs replacement based on whether the distances between multiple points on the drawn honing wheel contour map and their corresponding points on the standard honing wheel contour map are all greater than a set threshold. This avoids premature replacement based on experience, which increases operating costs, and the impact on product processing quality caused by untimely replacement of the honing wheel.
