[0071] As mentioned in the background art, conventional measurement is to measure the through hole on the large main bearing ring by using a measuring tool (such as an internal diameter micrometer, a depth gauge or a vernier caliper, etc.) or by image recognition.

[0072] Then, the above methods all require manual finding of the corresponding through holes and then measuring the through holes, which results in low detection efficiency.

[0073] In view of the above problems existing in the prior art, the present invention provides a bearing ring hole detection device and detection method. The bearing ring hole detection device includes a mounting platform, a first drive assembly, a second drive assembly, a third drive assembly and a probe assembly, and the probe assembly includes a probe body, a position sensor, a depth sensor and at least two radial sensing mechanisms. The present application drives the probe body to sequentially enter and exit multiple through holes on the bearing ring through the first drive assembly, the second drive assembly and the third drive assembly to complete the detection of the position coordinates, depth and diameter of each through hole. Compared with the manual detection method, the detection efficiency of the present application is high.

[0074] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0075] Reference Figures 1 to 5 As shown, the bearing ring hole detection device 10 provided in the present application includes a mounting platform 100 , a first drive assembly 200 , a second drive assembly 300 , a third drive assembly 400 and a probe assembly 500 .

[0076] The mounting platform 100 is disposed on the first driving assembly 200 , and the first driving assembly 200 is used to drive the mounting platform 100 to move circumferentially around the end surface of the bearing ring 20 .

[0077] The second drive assembly 300 is arranged on the mounting platform 100, the third drive assembly 400 is arranged on the second drive assembly 300, the probe assembly 500 includes a probe body 510, and the probe body 510 is arranged on the third drive assembly 400. The second drive assembly 300 is used to drive the third drive assembly 400 to move relative to the mounting platform 100 so that the probe body 510 is aligned with the through hole on the bearing ring 20, and the third drive assembly 400 is used to drive the probe body 510 to enter or exit the through hole.

[0078] The probe body 510 is provided with a position sensor 520 for determining the position coordinates of the through hole.

[0079] The probe body 510 is provided with a depth sensor 530 for measuring the depth of the through hole.

[0080] At least two radial sensing mechanisms 540 are disposed circumferentially on the circumference of the probe body 510 for measuring the diameter of the through hole.

[0081] It can be seen from the above description that the bearing ring hole detection device 10 of the present application drives the mounting platform 100 to perform circumferential movement around the end surface of the bearing ring 20 through the first driving component 200, so that the probe body 510 moves above the through hole to be detected, and under the action of the second driving component 300, the probe body 510 moves relative to the mounting platform 100, so that the alignment probe body 510 is aligned with the through hole to be detected, and then the probe body 510 is driven by the third driving component 400 to enter the through hole to be detected. After the probe body 510 enters the through hole to be detected, the position coordinates of the through hole are determined by the position sensor 520, the depth of the through hole is measured by the depth sensor 530, and the diameter of the through hole is measured by the radial sensing mechanism 540. After the detection of the through hole is completed, the probe body 510 detects the next through hole under the action of the first driving component 200, the second driving component 300 and the third driving component 400.

[0082] The present application drives the probe body 510 to sequentially enter and exit multiple through holes on the bearing ring 20 through the first drive assembly 200, the second drive assembly 300 and the third drive assembly 400 to complete the detection of each through hole. Compared with manual detection methods, the detection efficiency of the present application is high.

[0083] Exemplarily, the position sensor 520 can be a conventional position sensor. After the probe body 510 enters the through hole, the position sensor 520 records the current coordinates (x, y, z) of the through hole, wherein the coordinate system takes the depth direction of the through hole as the z direction, and then sends the coordinate system to an external control processing module. The external control processing module can be an implementation of a device including a single-chip microcomputer, an embedded chip, etc. The external control processing module can be used to control the first drive assembly 200, the second drive assembly 300, the third drive assembly 400, the position sensor 520, the depth sensor 530 and the radial sensor mechanism 540 to work.

[0084] Exemplarily, the depth sensor 530 may be a conventional depth sensor, and the depth sensor 530 is provided with a preload λ, and the value of λ may be set with reference to the accuracy of the depth sensor; before entering the through hole, the depth sensor 530 is pressed against the end surface of the bearing ring 20 to slide, and its preload reaches λ; after entering the through hole, the depth sensor 530 extends downward until it touches the bottom, and the depth measurement value h is obtained when the compression reaches λ. After completing the depth measurement, the depth sensor 530 retracts, and the retraction amount is h+2λ, and the depth sensor 530 is pressed against the end surface of the bearing ring 20 again.

[0085] It is understandable that there are at least two radial sensing mechanisms 540, and the number of radial sensing mechanisms 540 can be two, three, or more than three. The arithmetic mean of multiple diameter data measured by multiple radial sensing mechanisms 540 can be taken as the measurement value to ensure accuracy.

[0086] Reference Figure 2 and Figure 3 As shown, in some embodiments, the radial sensing mechanism 540 includes a movable rod 541, a telescopic rod 542, a telescopic sensing element and a telescopic rod driving assembly 543.

[0087] One end of the movable rod 541 is rotatably set on the probe body 510, one end of the telescopic rod 542 is set on the probe body 510, the end of the telescopic rod 542 away from the probe body 510 is connected to the movable rod 541, and the telescopic sensor is set on the telescopic rod 542 for detecting the telescopic amount of the telescopic rod 542.

[0088] The telescopic rod driving assembly 543 is disposed in the probe body 510 and is connected to the telescopic rod 542 to drive the telescopic rod 542 to extend or contract so as to move the movable rod 541 closer to or farther from the inner wall of the through hole.

[0089] In the above embodiment, after the probe body 510 enters the through hole, the probe body 510 can be centered in the through hole by the second driving assembly 300, and then the telescopic rod 542 is extended under the action of the telescopic rod driving assembly 543, so that the movable rod 541 rotates relative to the probe body 510 and abuts against the inner wall of the through hole. At this time, there is an angle θ between the movable rod 541 and the probe body 510, and the telescopic sensor detects the telescopic amount L' of the telescopic rod 542 at this time. The diameter d of the through hole can be calculated by the following formula:

[0090]

[0091] Among them, refer to Figure 6 As shown:

[0092] l1 is the distance between the end of the telescopic rod 542 on the probe body 510 and the end of the movable rod 541 on the probe body 510; l2 is the length of the movable rod 541; L is the initial length of the telescopic rod 542; L′ is the telescopic amount of the telescopic rod 542 detected by the telescopic sensor; d0 is the diameter of the probe body 510.

[0093] Exemplarily, the telescopic sensor may be a conventional telescopic sensor, which is mainly used to detect the telescopic amount of the telescopic rod 542 .

[0094] Specifically, refer to Figure 4 As shown, there are three radial sensing mechanisms 540 , which are evenly arranged on the circumferential side of the probe body 510 . After the three radial sensing mechanisms 540 respectively measure the diameter of the through hole, the arithmetic average value is taken as the measurement value.

[0095] Among them, refer to Figure 2 and Figure 3 As shown, a mounting chamber 560 is disposed in the probe body 510 , and the telescopic rod driving assembly 543 is disposed in the mounting chamber 560 .

[0096] Reference Figure 2 and Figure 3 As shown, in some embodiments, the telescopic rod driving assembly 543 includes a sliding rod 5431 , an elastic member 5432 , a pulley set 5433 and a traction rope 5434 .

[0097] A slide groove 5435 is provided in the probe body 510, and a sliding rod 5431 is slidably provided in the slide groove 5435, and one end of the sliding rod 5431 is exposed in the slide groove 5435, and an elastic member 5432 is provided between the sliding rod 5431 and the slide groove 5435, a pulley group 5433 is provided in the probe body 510, and a traction rope 5434 is wound around the pulley group 5433, one end of the traction rope 5434 is connected to the sliding rod 5431, and the other end of the traction rope 5434 is connected to the telescopic rod 542.

[0098] The sliding rod 5431 is configured so that the end away from the slide groove 5435 abuts against the end surface of the bearing ring 20, compresses the elastic member 5432, and puts the telescopic rod 542 into a retracted state through the traction rope 5434; the sliding rod 5431 enters the through hole, and under the action of the elastic member 5432, the sliding rod 5431 releases the restriction on the telescopic rod 542.

[0099] In the above embodiment, one end of the traction rope 5434 away from the telescopic rod 542 extends into the slide groove 5435 and is connected to the sliding rod 5431. When the probe body 510 has not entered the through hole, the sliding rod 5431 is abutted against the end face of the bearing ring 20 under the action of the third driving assembly 400 and squeezes the elastic member 5432. The elastic member 5432 is in an energy storage state. At this time, the sliding rod 5431 pulls the telescopic rod 542 through the traction rope 5434, and the telescopic rod 542 is in a contracted state, so that the movable rod 541 is close to the probe body 510.

[0100] After the probe body 510 enters the through hole, the elastic member 5432 drives the sliding rod 5431 to move, the sliding rod 5431 releases the restriction on the telescopic rod 542 , and the telescopic end of the telescopic rod 542 extends to drive the movable rod 541 to rotate relative to the probe body 510 .

[0101] After measuring the diameter of the through hole, the probe body 510 is retracted from the through hole through the third driving assembly 400, and the sliding rod 5431 is pressed against the end face of the bearing ring 20, compressing the elastic member 5432, and pulling the telescopic end of the telescopic rod 542 through the traction rope 5434 to put the telescopic rod 542 in a telescopic state. At this time, the movable rod 541 is moved toward the probe body 510.

[0102] When the mounting platform 100 moves under the action of the first driving assembly 200 , the sliding rod 5431 slides against the end surface of the bearing ring 20 .

[0103] Specifically, refer to Figure 3 As shown, the sliding rod 5431, the elastic member 5432, the pulley block 5433 and the traction rope 5434 are all arranged in the installation chamber 560 of the probe body 510. The telescopic rod 542 includes a sleeve portion and a telescopic portion, the sleeve portion is arranged on the probe body 510, the telescopic portion is slidably arranged in the sleeve portion, and one end of the traction rope 5434 extends into the sleeve portion and is connected to the telescopic portion.

[0104] Exemplarily, the elastic member 5432 may be a spring.

[0105] Wherein, in some embodiments, reference Figure 2 and Figure 3As shown, the depth sensor 530 may be disposed on one side of the end surface of the sliding rod 5431 facing the bearing ring 20 , so that the depth sensor 530 has a preload λ when the probe body 510 does not enter the through hole.

[0106] In some embodiments, the probe assembly 500 further includes at least two centering mechanisms (not shown in the figure), which are disposed on the circumference of the probe body 510 .

[0107] The centering mechanism includes a centering drive component and a pressure sensor component. Each pressure sensor component is correspondingly arranged at one end of each movable rod 541 away from the probe body 510. Each centering drive component is arranged on the probe body 510 and is correspondingly connected to each movable rod 541. The centering drive component is used to drive the movable rod 541 to rotate so that the pressure sensor component is close to or away from the inner wall of the through hole.

[0108] In the above embodiment, the centering mechanism can be used to ensure that the probe body 510 is in the center of the through hole. After the probe body 510 enters the through hole, the telescopic end of the telescopic rod 542 is extended, driving the movable rod 541 to rotate, and the pressure sensor is pressed against the inner wall of the through hole. When the probe body 510 is not centered, the pressures detected by each pressure sensor are different. At this time, the centering drive member can be used to drive the movable rod 541 to rotate until the pressures detected by each pressure sensor are the same, so as to improve the accuracy of the diameter measurement of the through hole.

[0109] Specifically, the self-aligning driving member may include a ball screw mechanism and a spring, wherein the spring connects the ball screw mechanism and the movable rod 541 , and the ball screw mechanism drives the spring to contract and extend, so that the movable rod 541 rotates.

[0110] It is understandable that there are at least two centering mechanisms, and the number of the centering mechanisms can be two, three, or more than three, as long as the number of the centering mechanisms is consistent with the number of radial sensing mechanisms 540, and the present application does not impose too many restrictions on this.

[0111] Among them, when the external control processing module determines that the pressures detected by each pressure sensor are the same, it can send instructions to the position sensor 520 to enable the position sensor 520 to determine the position coordinates of the through hole, which are the position coordinates of the center of the through hole, so as to improve the accuracy of subsequent analysis and processing of the through hole data.

[0112] Reference Figure 2 and Figure 3 As shown, in some embodiments, at least two movable rod mounting seats 550 are disposed on the probe body 510 , and each movable rod 541 is hinged to each movable rod mounting seat 550 .

[0113] In the above embodiment, the movable rod mounting seat 550 is mainly used for mounting the movable rod 541 so that the movable rod 541 can rotate relative to the probe body 510 .

[0114] It is understandable that there are at least two movable rod mounting seats 550 , and the number of movable rod mounting seats 550 can be two, three, or more than three, as long as the number of movable rod mounting seats 550 is consistent with the number of movable rods 541 , and the present application does not impose too many restrictions on this.

[0115] Reference Figure 1 As shown, in some embodiments, the first driving assembly 200 includes a first driving member, a traveling wheel set 210 and at least one guide wheel 220 disposed on the mounting platform 100;

[0116] The first driving member is connected to the traveling wheel set 210 , and the first driving member is configured to drive the traveling wheel set 210 to roll around the end surface of the bearing ring 20 ;

[0117] The guide wheel 220 is arranged so as to abut against the peripheral side of the bearing ring 20 .

[0118] In the above embodiment, the traveling wheel set 210 and the guide wheel 220 can both rotate relative to the mounting platform 100. The traveling wheel set 210 may include a driving wheel and a driven wheel that are rotatably connected, the driving wheel is connected to the first driving member, and the driving wheel and the driven wheel are both in contact with the end surface of the bearing ring 20. Under the action of the first driving member, the driving wheel and the driven wheel roll on the end surface of the bearing ring 20, so that the mounting platform 100 moves relative to the bearing ring 20.

[0119] The guide wheel 220 abuts against the circumferential side of the bearing ring 20 to play a guiding role, so that the mounting platform 100 moves circumferentially around the end surface of the bearing ring 20 .

[0120] Reference Figure 1 As shown, in some embodiments, the first driving assembly 200 further includes at least one adjusting rod 230 , and the adjusting rod 230 is disposed on the mounting platform 100 .

[0121] One end of each adjusting rod 230 away from the installation platform 100 is connected to each guide wheel 220 accordingly. The adjusting rod 230 is used to make the guide wheel 220 approach or move away from the installation platform 100.

[0122] In the above embodiment, when the bearing ring hole detection device 10 is installed on the bearing ring 20, the guide wheel 220 can be moved closer to or away from the mounting platform 100 by adjusting the adjustment rod 230 to adjust the contact position between the guide wheel 220 and the bearing ring 20 to ensure the stability of the movement.

[0123] Exemplarily, the adjustment rod 230 may be a screw rod, and a threaded hole may be provided on the mounting platform 100 , and the adjustment rod 230 is threadedly connected in the threaded hole.

[0124] It is understandable that there is at least one guide wheel 220 and at least one adjustment rod 230, as long as the number of guide wheels 220 and adjustment rods 230 is the same, and the present application does not impose too many restrictions on this.

[0125] Reference Figure 1 As shown, in some embodiments, the second driving assembly 300 includes a sliding seat 310 , a sliding rail and a guide rod 320 .

[0126] The slide rail is arranged on the mounting platform 100 , the sliding seat 310 is slidably disposed on the slide rail, the third driving assembly 400 is disposed on the sliding seat 310 , and the guide rod 320 is disposed between the probe mounting seat and the mounting platform 100 .

[0127] In the above embodiment, the sliding seat 310 can be driven to slide on the slide rail so that the probe body 510 on the third driving assembly 400 is aligned with the through hole to be detected. The guide rod 320 is mainly used to guide and improve the stability of the movement of the sliding seat 310.

[0128] Specifically, refer to Figure 1 As shown, a working opening is provided on the mounting platform 100, and the third driving assembly 400 and the probe body 510 both extend into the bottom of the mounting platform 100 through the working opening. When the sliding seat 310 slides on the slide rail, the third driving assembly 400 and the probe body 510 both move in the working opening, so that the overall structure is more compact.

[0129] Among them, refer to Figure 1 As shown, the second driving assembly 300 further includes a positioning plate 330 , the positioning plate 330 is disposed on the mounting platform 100 , and the guide rod 320 is disposed between the positioning plate 330 and the sliding seat 310 .

[0130] For example, the sliding seat 310 can be driven manually, which has a simple structure and low manufacturing cost. Of course, the sliding seat 310 can also be driven by a linear drive module such as a ball screw mechanism, a pulley conveying mechanism, etc., to save labor costs and improve detection efficiency.

[0131] Reference Figure 1 As shown, in some embodiments, the third drive assembly 400 can be a ball screw mechanism.

[0132] In the above embodiment, the ball screw mechanism is used to drive the probe body 510 to perform linear motion so that the probe body 510 can enter or exit the through hole.

[0133] Reference Figure 7 As shown, the bearing ring hole detection method provided by the present application uses the above bearing ring hole detection device 10 to detect the depth, diameter and position coordinates of each through hole on the bearing ring. The method includes:

[0134] S101. The first driving assembly 200 of the bearing ring hole detection device 10 drives the mounting platform 100 of the bearing ring hole detection device 10 to move circumferentially around the end surface of the bearing ring 20, so that the probe body 510 of the bearing ring hole detection device 10 moves to above the through hole to be detected.

[0135] In this step, the first driving assembly 200 drives the mounting platform 100 to move so that the probe body 510 on the mounting platform 100 moves to the top of the through hole to be detected, so as to facilitate the detection thereof. After completing the detection of the through hole, the first driving assembly 200 drives the mounting platform 100 to move toward the next through hole.

[0136] S102 , the second driving assembly 300 of the bearing ring hole detection device 10 drives the probe body 510 and the third driving assembly 400 of the bearing ring hole detection device 10 to move relative to the mounting platform 100 so that the probe body 510 is aligned with the through hole to be detected.

[0137] In this step, the second driving assembly 300 is mainly used to align the probe with the through hole to be inspected, so as to facilitate the subsequent entry of the probe body 510 into the through hole.

[0138] S103, the third driving component 400 drives the probe body 510 to enter the through hole to be detected, measures the diameter of the through hole to be detected by the radial sensing mechanism 540 of the bearing ring hole detection device 10, measures the depth of the through hole to be detected by the depth sensing component 530 of the bearing ring hole detection device 10, and determines the position coordinates of the through hole to be detected by the position sensing component 520 of the bearing ring hole detection device 10.

[0139] In this step, the third driving assembly 400 is used to drive the probe body 510 to enter the through hole to be inspected, and inspect the through hole through the position sensor 520, the depth sensor 530 and the radial sensor mechanism 540 to obtain the size data of the through hole.

[0140] S104 , the third driving assembly 400 drives the probe body 510 to exit the through hole, and the first driving assembly 200 drives the mounting platform 100 to move toward the next through hole to be detected.

[0141] In this step, after completing the inspection of one through hole, the probe body 510 continues to inspect the next through hole under the action of the first drive component 200, the second drive component 300 and the third drive component 400, and the cycle is repeated until all the through holes on the bearing ring 20 are inspected.

[0142] By means of this detection method, the detection efficiency of each through hole on the bearing ring 20 can be improved.

[0143] In some embodiments, the bearing ring hole detection method further includes:

[0144] S105 , after the mounting platform 100 moves around the bearing ring 20 for one circle, the depth, diameter and position coordinate data of each through hole are obtained.

[0145] In this step, the mounting platform 100 moves around the bearing ring 20 for one circle to obtain data such as position coordinates, depths, and diameters of all through holes on the bearing ring 20 .

[0146] The position coordinates are three-dimensional space coordinates (x, y, z), and z may be the depth direction of the through hole.

[0147] S106, comparing each through hole with a preset standard value, selecting each through hole that meets the diameter deviation range and the position deviation range, and performing least square fitting on the position coordinates to obtain the distribution position and distribution center diameter of each through hole.

[0148] In this step, the diameter deviation range may be d±0.2, and the position deviation range may be the distance range requirement between a preset standard through hole on the bearing ring and the axis of the bearing ring.

[0149] Preferably, in consideration of the position deviation range, the position deviation range can be converted into an influence on the diameter d, so that the diameter deviation range can be d±0.5.

[0150] When performing least square fitting on the position coordinates of the through holes that meet the conditions, only the (x, y) coordinates thereof may be selected for fitting.

[0151] S107, the qualified rate of the through holes on the bearing ring is obtained by calculating the ratio of the number of through holes involved in the least square fitting to the number of all through holes detected by the bearing ring hole detection device 10, and unqualified through holes are marked according to the position coordinates.

[0152] In this step, unqualified through holes are marked for subsequent qualification inspection.
