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

[0072] Then, the above methods all require manual work to find the corresponding through holes and then measure the through holes, resulting in low detection efficiency.

[0073] To address the aforementioned issues in the prior art, the present invention provides a bearing ring hole detection device and method. The bearing ring hole detection device comprises a mounting platform, a first drive assembly, a second drive assembly, a third drive assembly, and a probe assembly. The probe assembly comprises a probe body, a position sensor, a depth sensor, and at least two radial sensing mechanisms. The present invention utilizes the first, second, and third drive assemblies to drive the probe body into and out of multiple through-holes on the bearing ring in sequence, thereby detecting the position coordinates, depth, and diameter of each through-hole. Compared to manual detection methods, the present invention offers high detection efficiency.

[0074] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. 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 circumferentially provided on the circumference of the probe body 510 for measuring the diameter of the through hole.

[0081] From the above description, it can be seen that the bearing ring hole detection device 10 of the present application drives the mounting platform 100 to move circumferentially around the end face of the bearing ring 20 through the first drive component 200, so that the probe body 510 moves above the through hole to be detected, and under the action of the second drive 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 into the through hole to be detected by the third drive component 400. 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 sensor 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 drive component 200, the second drive component 300 and the third drive 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] For example, the position sensor 520 may be a conventional position sensor. After the probe body 510 enters the through hole, the position sensor 520 records the current coordinates of the through hole. , where the coordinate system is based on the depth direction of the through hole The coordinate system is then sent to an external control processing module. The external control processing module can be implemented as a single-chip microcomputer, an embedded chip, or other device. The external control processing module can be used to control the operation of 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 sensing mechanism 540.

[0084] For example, the depth sensor 530 may be a conventional depth sensor, and the depth sensor 530 is provided with a preload , The value can be set with reference to the accuracy of the depth sensor; when not entering the through hole, the depth sensor 530 is pressed against the end surface of the bearing ring 20 and slides, and its preload reaches After entering the through hole, the depth sensing member 530 extends downward until it touches the bottom, and the compression reaches Depth measurement is obtained when After the depth measurement is completed, the depth sensor 530 retracts by , the depth sensor 530 is again pressed against the end surface of the bearing ring 20.

[0085] It can be understood 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 average 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 member, 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, and the end of the telescopic rod 542 away from the probe body 510 is connected to the movable rod 541. 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 for driving the telescopic rod 542 to extend or retract so as to move the movable rod 541 closer to or away 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 between the movable rod 541 and the probe body 510. The telescopic sensor detects the telescopic amount of the telescopic rod 542 at this time , the diameter of the through hole It can be obtained by the following formula:

[0090]

[0091] Among them, reference Figure 6 As shown:

[0092] 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; is the length of the movable rod 541; is the initial length of the telescopic rod 542; The telescopic amount of the telescopic rod 542 detected by the telescopic sensor; 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 is taken as the measurement value.

[0095] Among them, reference Figure 2 and Figure 3 As shown, a mounting chamber 560 is provided 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 the 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, the elastic member 5432 is provided between the sliding rod 5431 and the slide groove 5435, the pulley group 5433 is provided in the probe body 510, and the 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 face 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, the 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 drive 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 withdrawn from the through hole again through the third drive 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 3As shown, the sliding rod 5431, the elastic member 5432, the pulley assembly 5433, and the traction rope 5434 are all disposed in the mounting chamber 560 of the probe body 510. The telescopic rod 542 includes a sleeve portion and a telescopic portion. The sleeve portion is disposed on the probe body 510, and the telescopic portion is slidably disposed within the sleeve portion. 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] In some embodiments, reference Figure 2 and Figure 3 As shown, the depth sensor 530 can be arranged on the side of the end surface of the sliding rod 5431 facing the bearing ring 20, so that the depth sensor 530 has a preload 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 figures), which are disposed on the circumference of the probe body 510 .

[0107] The centering mechanism includes a centering drive component and a pressure sensing component. Each pressure sensing 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 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 sensing component is close to or away from the inner wall of the through hole.

[0108] In the above embodiment, a centering mechanism ensures that the probe body 510 is centered within the through-hole. After the probe body 510 enters the through-hole, the telescopic end of the telescopic rod 542 extends, driving the movable rod 541 to rotate and causing the pressure sensing element to rest against the inner wall of the through-hole. If the probe body 510 is not centered, the pressures detected by the various pressure sensing elements will differ. In this case, the centering drive element can be used to rotate the movable rod 541 until the pressures detected by the various pressure sensors are the same, thereby improving the accuracy of the through-hole diameter measurement.

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

[0110] It can be understood that there are at least two centering mechanisms, and the number of centering mechanisms can be two, three, or more than three, as long as the number of centering mechanisms is consistent with the number of radial sensing mechanisms 540. This 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 sensing component 520 to enable the position sensing component 520 to determine the position coordinates of the through hole. The position coordinates 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 provided 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. This 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 come into contact with the peripheral side of the bearing ring 20 .

[0118] In the above embodiment, the traveling wheel assembly 210 and the guide wheel 220 can both rotate relative to the mounting platform 100. The traveling wheel assembly 210 can include a driving wheel and a driven wheel that are rotatably connected. The driving wheel is connected to the first driving member. The driving wheel and the driven wheel both abut against 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, thereby moving the mounting platform 100 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 adjustment rod 230 away from the installation platform 100 is correspondingly connected to each guide wheel 220 . The adjustment rod 230 is used to move the guide wheel 220 closer to or 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 through 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] For example, the adjusting rod 230 may be a screw rod, and a threaded hole may be provided on the mounting platform 100 , and the adjusting 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 this application does not impose too many restrictions on this.

After completing the inspection of the through hole, the first drive 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 into the through hole to be detected, measures the diameter of the through hole to be detected through the radial sensing mechanism 540 of the bearing ring hole detection device 10, measures the depth of the through hole to be detected through 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 through 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 into 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 inspected.

[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 using 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 the position coordinates, depth, and diameter of all through holes on the bearing ring 20 .

[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 can be The position deviation range can be the distance range requirement between the 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 the diameter The influence of the diameter deviation range can be .

[0150] Among them, when performing least square fitting on the position coordinates of the through holes that meet the conditions, only the Coordinates are fitted.

[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 squares 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 their position coordinates.

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