Background

At present, the eccentricity of the waist wheel rotor is detected mainly by adopting a three-coordinate method, but the detection efficiency of the three-coordinate method is lower, and the requirement of preparing the waist wheel rotor in a large quantity cannot be met.

The apparatus and method for detecting lumbar wheels according to the present application will be described in detail with reference to specific examples.
Referring to fig. 1 to 4, the present application provides a lumbar wheel hub detecting device, which includes a base 100 and a detecting assembly 200. The detection device can be applied to the detection method of the waist wheel rotor 300.
Wherein, the base 100 is a basic component of the detection device of the lumbar wheel rotor 300 of the present application, and the base 100 can provide a mounting base for other at least partial components of the detection device of the lumbar wheel rotor 300 and serve the purpose of protecting the other at least partial components. The base 100 may be made of a metal material, so that the base 100 has better structural strength, thereby making the base 100 more durable and reliable. Of course, the base 100 may also be made of a polymer material, so that the base 100 has a certain structural strength and is relatively light in weight.
The base 100 includes a bearing portion 111 for bearing the lumbar wheel rotor 300, and the lumbar wheel rotor 300 may be fixed on the bearing portion 111 of the base 100, so that the lumbar wheel rotor 300 and the base 100 may be relatively fixed, and thus the lumbar wheel rotor 300 may remain stable, so as to improve the detection accuracy of the lumbar wheel rotor 300.
The waist wheel rotor 300 comprises a rotor body and a rotating shaft 320, wherein the rotor body is of a waist-shaped structure, a waist-shaped groove 310 is formed in the rotor body, and the waist-shaped groove 310 is located in the middle of the rotor body. The rotor body is further provided with fixing through holes 330 positioned at both sides of the kidney-shaped groove 310, and the two fixing through holes 330 are symmetrically arranged along the center of the rotor body. The base 100 includes a reference plane 120, and the line connecting the central axes of the two fixing holes 330 is parallel to the reference plane 120. The rotating shaft 320 is disposed through the middle part of the rotor body, the direction of the axis of the rotating shaft 320 is consistent with the direction of the axis of the kidney-shaped slot 310, and the axis of the rotating shaft 320 is also parallel to the reference plane 120. Ideally, the projection of the central axis of the rotating shaft 320 on the reference plane 120 should coincide with the projection of the central axis of the kidney-shaped slot 310 on the reference plane 120, but due to the limitation of the current preparation process, a certain deviation may exist between the projection of the central axis of the rotating shaft 320 on the reference plane 120 and the projection of the central axis of the kidney-shaped slot 310 on the reference plane 120, and the distance between the projection of the central axis of the kidney-shaped slot 310 on the reference plane 120 and the projection of the central axis of the rotating shaft 320 on the reference plane 120 is the eccentricity of the projection of the central axis of the kidney-shaped slot 310 on the reference plane 120 and the projection of the central axis of the rotating shaft 320 on the reference plane 120.
The lumbar wheel rotor 300 further includes a first portion 311 and a second portion 312, where the first portion 311 and the second portion 312 are located on the inner wall of the kidney-shaped slot 310 of the lumbar wheel rotor 300 and distributed on the inner walls of the two sides of the kidney-shaped slot 310. Specifically, the first portion 311 and the second portion 312 are located at two sides of a predetermined plane, where the predetermined plane is a plane passing through the central axis of the kidney-shaped slot 310 and perpendicular to the reference plane 120. The predetermined plane is the Y plane in fig. 3 and 4. The distance between the first portion 311 and the preset plane is the same as the distance between the second portion 312 and the preset plane, and when the lumbar wheel rotor 300 is disposed on the carrying portion 111, the detecting assembly 200 is configured to detect the height of the first portion 311 relative to the reference plane 120 and detect the height of the second portion 312 relative to the reference plane 120.
After the height of the first portion 311 of the lumbar wheel rotor 300 to be measured relative to the reference surface 120 and the height of the second portion 312 of the lumbar wheel rotor 300 to be measured relative to the reference surface 120 are obtained by the detection device for the lumbar wheel rotor 300 of the present application, the height of the first portion 311 of the lumbar wheel rotor 300 to be measured relative to the reference surface 120 and the height of the second portion 312 of the lumbar wheel rotor 300 to be measured relative to the reference surface 120 can be taken into the following formula: . Wherein, To measure the eccentricity of the central axis of the kidney-shaped groove 310 of the waist-shaped wheel rotor 300 and the central axis of the rotating shaft 320,To be measured is the height of the first portion 311 of the lumbar wheel rotor 300 relative to the reference surface 120,To determine the height of the second portion 312 of the lumbar wheel rotor 300 relative to the reference surface 120,As the height of the first portion of the reference lumbar wheel rotor relative to the reference plane 120,As the height of the second portion of the reference lumbar wheel rotor relative to the reference plane 120,Is the eccentricity of the middle shaft of the waist-shaped groove of the reference waist-shaped wheel rotor and the middle shaft of the rotating shaft,The value of (2) is-1.22 to-0.76.
Of course, it should be understood that, in order to obtain the height of the first portion 311 relative to the reference surface 120 and the height of the second portion 312 relative to the reference surface 120, the heights of the first portion 311 and the second portion 312 relative to other components may also be detected by the detecting unit 200, and the heights of the first portion 311 relative to the reference surface 120 and the second portion 312 relative to the reference surface 120 may be calculated by the height of the reference surface 120. The present application is not limited as to the manner in which the height of the first portion 311 with respect to the reference surface 120 and the height of the second portion 312 with respect to the reference surface 120 are specifically obtained.
It should be understood that the eccentricity of the central axis of the kidney-shaped groove of the reference waist wheel rotor and the central axis of the rotating shaft thereof is a known value, and the eccentricity of the central axis of the kidney-shaped groove of the reference waist wheel rotor and the central axis of the rotating shaft thereof can be obtained in other manners, specifically, the eccentricity of the central axis of the kidney-shaped groove of the reference waist wheel rotor and the central axis of the rotating shaft thereof can be obtained by a three-coordinate method. This brings the above-mentioned parameters into the formula: then, the eccentricity between the central axis of the kidney-shaped groove 310 of the lumbar wheel rotor 300 to be measured and the central axis of the rotating shaft 320 thereof can be obtained.
Specifically, when the lumbar wheel rotor 300 to be measured is detected by the lumbar wheel rotor detecting device of the present application, the height of the first portion of the reference lumbar wheel rotor with respect to the reference surface 120 and the height of the second portion of the reference lumbar wheel rotor with respect to the reference surface 120 may be detected by the lumbar wheel rotor detecting device. After the lumbar wheel rotor 300 to be measured is disposed on the mounting portion 111 of the base 100, the height of the first portion 311 of the lumbar wheel rotor 300 to be measured relative to the reference surface 120 and the height of the second portion 312 of the lumbar wheel rotor 300 to be measured relative to the reference surface 120 are obtained, and the above parameters are taken into the formula: Then, the eccentricity between the central axis of the kidney-shaped groove 310 of the lumbar wheel rotor 300 to be measured and the central axis of the rotating shaft 320 thereof can be obtained. When detecting different lumbar wheel rotors 300 to be detected, only the heights of the first parts 311 of the lumbar wheel rotors 300 to be detected relative to the reference surface 120 and the heights of the second parts 312 of the lumbar wheel rotors 300 to be detected relative to the reference surface 120 are detected, so that the eccentricity between the central axis of the waist-shaped groove 310 of the lumbar wheel rotor 300 to be detected and the central axis of the rotating shaft 320 of the waist-shaped groove is obtained, the efficiency of detecting the eccentricity between the central axis of the waist-shaped groove 310 of the lumbar wheel rotor 300 to be detected and the central axis of the rotating shaft 320 of the waist-shaped groove is greatly improved, and the preparation efficiency of the lumbar wheel rotor 300 is greatly improved.
In some embodiments, referring to fig. 1 and 5, it should be understood that the kidney-shaped groove 310 of the lumbar wheel rotor 300 to be measured is a groove-shaped structure extending along the axis of the rotating shaft 320, and correspondingly, the kidney-shaped groove 310 has different portions adjacent to two ends of the rotating shaft 320, and different portions of the kidney-shaped groove 310 in the axial direction thereof may also deviate from each other along with the corresponding central axis due to the limitation of the processing technology of the lumbar wheel rotor 300. In order to further improve the structural accuracy of the lumbar wheel rotor 300, the lumbar wheel rotor 300 of the present application may include at least two first portions 311 and at least two second portions 312, wherein the at least two first portions 311 are distributed along the axial direction of the kidney-shaped slot 310, the at least two second portions 312 are also distributed along the axial direction of the kidney-shaped slot 310, and the at least two first portions 311 are disposed in one-to-one correspondence with the at least two second portions 312.
Specifically, one first portion 311 of the at least two first portions 311 may form a detection portion group with a corresponding one second portion 312, so that the number of detection portion groups is also at least two. The first portion 311 and the second portion 312 of any one of the detecting portion groups are located on the inner wall of the kidney-shaped slot 310 of the lumbar wheel rotor 300, and are distributed on the inner walls of both sides of the kidney-shaped slot 310. Correspondingly, the at least two detecting portion groups are also distributed along the axial direction of the kidney-shaped slot 310, and the first portion 311 and the second portion 312 of the at least two detecting portion groups may correspond to different portions of the axial direction of the kidney-shaped slot 310.
When the lumbar wheel rotor 300 is disposed on the carrying portion 111, the detecting assembly 200 is configured to detect the height of the first portion 311 relative to the reference surface 120 and the height of the second portion 312 relative to the reference surface 120 in any one of the detecting portion groups. That is, the detecting assembly 200 may detect the heights of the plurality of first portions 311 relative to the reference surface 120 and the heights of the plurality of second portions 312 relative to the reference surface 120. This is accomplished by taking the heights of the plurality of first locations 311 relative to the datum 120 and the heights of the plurality of second locations 312 relative to the datum 120 into the formula: After that, the eccentricity of the central axis of the waist-shaped groove 310 between each part of the extending direction thereof and the central axis of the rotating shaft 320 can be obtained, so that the light-weight precision of the waist-shaped wheel rotor 300 can be more sufficiently detected, and the preparation precision of the waist-shaped wheel rotor 300 can be further improved in the process of preparing the waist-shaped wheel rotor 300.
In some embodiments, referring to fig. 1 and 2, in order for the detection assembly 200 to detect the height of the first portion 311 relative to the reference surface 120 and the height of the second portion 312 relative to the reference surface 120 in the plurality of detection portion groups, the detection assembly 200 may be configured to include a plurality of detection members 210.

This can improve the detection efficiency of the detection assembly 200, and thus the efficiency of detecting the eccentricity of the central axis of the kidney-shaped groove 310 of the waist-shaped wheel rotor 300 and the central axis of the rotation shaft 320 by the waist-shaped wheel rotor 300 detection device of the present application can be improved.
In some embodiments, referring to fig. 3 to 5, in order for the detecting member 210 of the present application to detect the height of the first portion 311 of the lumbar wheel 300 with respect to the reference surface 120 and the height of the second portion 312 with respect to the reference surface 120, the detecting member 210 may be configured as a dial indicator. The detecting member 210 has a detecting end 211, and the detecting end 211 is the end of the pointer of the dial indicator. When the lumbar wheel rotor 300 is not yet disposed at the bearing portion 111 of the base 100, the first portion 311 or the second portion 312 of the lumbar wheel rotor 300 is not in contact with the detecting end 211 of the detecting element 210, and the detecting end 211 of the detecting element 210 is in a natural state. When the lumbar wheel rotor 300 is disposed at the bearing portion 111 of the base 100, the detecting end 211 abuts against the first portion 311 or the second portion 312 of the lumbar wheel rotor 300, the detecting end 211 is pressed by the first portion 311 or the second portion 312 to shrink, and the distance between the detecting end 211 and the reference surface 120 can be changed, so that the detecting element 210 can generate a value, which is the height of the first portion 311 relative to the reference surface 120 or the height of the second portion 312 relative to the reference surface 120. Thus, the height of the first portion 311 relative to the reference surface 120 or the height of the second portion 312 relative to the reference surface 120 can be obtained by reading the value of the dial indicator, so that the process of obtaining the height of the first portion 311 relative to the reference surface 120 and the height of the second portion 312 relative to the reference surface 120 is simple and convenient. Finally, the efficiency of detecting the eccentricity of the central axis of the kidney-shaped groove 310 of the waist-shaped wheel rotor 300 and the central axis of the rotating shaft 320 by the waist-shaped wheel rotor 300 detecting device can be improved.
It should be understood that, when the lumbar wheel rotor 300 is disposed at the bearing portion 111 of the base 100, the plurality of detecting members 210 can detect the height of the first portion 311 of the plurality of detecting portion groups relative to the reference surface 120. Then, the lumbar wheel 300 may be rotated 180 degrees and then disposed at the bearing portion 111 of the base 100, and at this time, the heights of the second portions 312 in the plurality of detecting portion groups with respect to the reference surface 120 may be detected by the plurality of detecting members 210, so that the heights of the first portions 311 in the detecting portion group with respect to the reference surface 120 and the heights of the second portions 312 with respect to the reference surface 120 may be detected.
In some embodiments, referring to fig. 1, 2,5 and 6, when the detecting element 210 is a dial indicator, the detecting element 210 further includes a gauge body 220, and the gauge body 220 is a main body structure of the dial indicator. In order to enable the detection member 210 to be disposed on the base 100, the reference surface 120 is provided with a mounting hole 130, and the mounting hole 130 is a through hole. The detecting end 211 of the detecting element 210 may be disposed through the mounting hole 130, and the surface body is disposed above the reference surface 120, and correspondingly, the bearing portion 111 is disposed below the mounting hole 130, so that when the lumbar wheel rotor 300 is disposed on the bearing portion 111, the detecting end 211 of the detecting element 210 may face the lumbar wheel rotor 300.
Specifically, the base 100 may further include a fixing hole 140, where the fixing hole 140 is connected to the mounting hole 130, and an axis of the fixing hole 140 intersects with an axis of the mounting hole 130, and when a portion of the detecting member 210 is disposed through the mounting hole 130, the detecting member 210 may be fixed to the base 100 by passing through the fixing hole 140 and abutting against a side wall of the portion of the detecting member 210 located in the mounting hole 130. Specifically, the fixing member may be provided as a bolt, and the fixing hole 140 may be provided as a screw hole. Of course, the reference surface 120 of the base 100 may also be provided to support the watch body, so that the detecting member 210 may be fixed to the base 100.
In some embodiments, in order to ensure that the lumbar rotor is stable when disposed at the bearing portion 111, the lumbar rotor detection device of the present application further includes a limiting member 400, the limiting member 400 is disposed on the base 100, and the limiting member 400 is configured to limit two ends of the lumbar rotor 300 on the axis of the rotating shaft 320, so that when the lumbar rotor 300 is disposed at the bearing portion 111 after rotating 180 degrees, the distance between the first portion 311 and the second portion 312 and the preset plane can be kept consistent.
In some embodiments, the limiting member 400 may include two limiting portions 410, where the two limiting portions 410 are disposed on the base 100, and when the lumbar wheel rotor 300 is disposed on the bearing portion 111, the two limiting portions 410 abut against two ends of the lumbar wheel rotor 300 on the axis of the 320 rotation shaft. Such two limiting portions 410 limit the lumbar wheel rotor 300 between the two limiting portions 410, so that the lumbar wheel rotor 300 is stable during detection.
In some embodiments, referring to fig. 1 and 7, in order to make the lumbar wheel rotor 300 more stable when being disposed on the bearing portion 111 of the base 100, the base 100 and the two limiting portions 410 may also enclose to form a fixing groove 110, and the bearing portion 111 is located in the fixing groove 110. Therefore, when the lumbar wheel rotor 300 is disposed on the bearing portion 111, at least a portion of the lumbar wheel rotor 300 is located in the fixing groove 110. Specifically, the slot shape of the fixing slot 110 may be matched with the shape of the lumbar wheel rotor 300, so that when the lumbar wheel rotor 300 is disposed in the fixing slot 110, the outer wall of the lumbar wheel rotor 300 abuts against the bottom wall of the fixing slot 110, or has a smaller distance. The inner wall of the fixing groove 110 can serve the purpose of limiting the lumbar wheel rotor 300, and the lumbar wheel rotor 300 is prevented from shaking after being arranged at the bearing part 111.
The base 100 has a limiting surface 150, the limiting surface 150 is located in the fixing groove 110, and the limiting surface 150 is opposite to a notch of the fixing groove 110. When the lumbar wheel rotor 300 is located at the bearing portion 111, the limiting surface 150 limits the lumbar wheel rotor 300 in a direction parallel to the reference surface 120 and perpendicular to the axis of the rotating shaft 320. By the cooperation of the limiting surface 150 and the limiting portion 410, the lumbar wheel rotor 300 can be relatively fixed in the direction parallel to the reference surface 120, so that the detection of the lumbar wheel rotor 300 is more accurate.
In some embodiments, referring to fig. 1 and 7, the limiting portion 410 of the present application may further include a positioning surface 411, where the positioning surface 411 is located at one side of the slot of the fixing slot 110, and when the lumbar wheel rotor 300 is disposed on the bearing portion 111, the rotating shaft 320 of the lumbar wheel rotor 300 abuts against the positioning surface 411. Thus, the positioning surface 411 and the rotating shaft 320 can be mutually limited and fixed, so that the waist wheel rotor 300 and the positioning surface 411 can be mutually limited and fixed, and the waist wheel rotor 300 is more stable when being arranged on the bearing part 111.
In some embodiments, referring to fig. 1 and 7, since the number of the limiting portions 410 is two, and accordingly the number of the positioning surfaces 411 is also two, the two positioning surfaces 411 are located at two sides of the notch of the fixing slot 110, and when the lumbar-wheel rotor 300 is disposed at the bearing portion 111, two sides of the rotating shaft 320 of the lumbar-wheel rotor 300 respectively abut against the two positioning surfaces 411. In this way, the stress on both sides of the rotating shaft 320 is balanced, so that the rotating shaft 320 is more stable when being abutted against the positioning surface 411, and the lumbar wheel 300 is more stable when being arranged on the bearing part 111.
Referring to fig. 8, the application also provides a method for detecting the lumbar wheel rotor, which can be applied to the lumbar wheel rotor detection device. The method comprises the following steps:
S100, setting the lumbar wheel to be tested on a reference surface. At this time, the part of the waist wheel rotor to be measured is positioned in the fixed groove of the base, and the waist wheel rotor to be measured can keep stable in structure.
S200, acquiring the height difference of the first part of the waist wheel rotor to be tested relative to the reference surface and the height difference of the second part of the waist wheel rotor to be tested relative to the reference surface.
S300, according to a first formula, the eccentricity of the projection of the central axis of the waist-shaped groove of the waist-shaped wheel rotor to be measured on the reference surface and the projection of the central axis of the rotating shaft on the reference surface is obtained.
The first formula is:
Wherein L is the eccentricity of the projection of the middle shaft of the waist-shaped groove of the waist-shaped wheel rotor to be measured on the reference surface and the projection of the middle shaft of the rotating shaft on the reference surface, The height of the first part relative to the reference surface,And R is the radius of the circumference of the kidney-shaped groove, and d is the diameter of the rotating shaft.
Specifically, referring to fig. 9, M is the center of the rotating shaft, MN is the center of the rotating shaft, and a straight line perpendicular to the reference plane, O is the center of the circumference of the waist-shaped groove, B is the first portion, C is the second portion, and both the straight line AB and the straight line CD are parallel to the reference plane. h is the absolute value of the difference between the height difference between the first location and the reference plane and the height difference between the second location and the reference plane 120.
From the above equation, we can solve (A-1)
For the same type of lumbar wheel, the diameter d of the h and the rotating shaft are greatly different,,Therefore, the formula (A-1) can be simplified into (A-2)
H is proportional to the eccentricity L. Order the
,Is the difference between the height of the first part and the reference surface,Is the difference between the height of the second part and the reference planeWhen it is eccentric(A-2)
Is to be of (A-3)
It should be understood that in the above formula, the difference between the height of the first portion and the reference surface is greater than the difference between the height of the second portion and the reference surface. Of course, if the difference between the height of the second portion and the reference surface is greater than the difference between the height of the first portion and the reference surface, the formula isAnd (3) withAnd correspondingly exchanged.
In some embodiments, it should be understood that when the difference between the first location and the reference plane and the difference between the second location and the reference plane are obtained by the lumbar wheel rotation detection device of the present application, measurement errors caused by errors of the device itself need to be considered, and thus, correction of the measurement structure is also required.
Therefore, step S300 in the present application further includes:
S310, according to a second formula: And obtaining the eccentricity of the projection of the central axis of the waist-shaped groove of the waist-shaped wheel rotor to be measured on the reference surface and the projection of the central axis of the rotating shaft on the reference surface.
Wherein, For the eccentricity of the projection of the middle shaft of the waist-shaped groove of the waist-shaped wheel rotor to be measured on the reference surface and the projection of the middle shaft of the rotating shaft on the reference surface,Is the height of the first part of the waist wheel rotor to be measured relative to the reference surface,For the height of the second part of the waist wheel rotor to be measured relative to the reference surface,Is the height of the first part of the reference waist wheel rotor relative to the reference surface,Is the height of the second part of the reference waist wheel rotor relative to the reference surface,Is the eccentricity of the projection of the middle shaft of the waist-shaped groove of the reference waist-shaped wheel rotor on the reference surface and the projection of the middle shaft of the rotating shaft on the reference surface,The value of (2) is-1.22 to-0.76.
Specifically, the eccentricity of the projection of the middle axis of the waist-shaped groove of the reference waist-wheel rotor on the reference surface and the projection of the middle axis of the rotating shaft on the reference surface can be measured by other testing tools and testing methods, and can be measured by a three-coordinate method. The height of the first part of the lumbar wheel rotor to be measured relative to the reference surface and the height of the second part of the lumbar wheel rotor to be measured relative to the reference surface can be measured by the lumbar wheel rotor detection device.
