[0003] During the production process of bearings, there is a process link of assembling bearing retaining rings. During the assembly process, the retaining ring needs to be pressed into the inner cavity of the bearing at a certain angle so that several needle rollers are restrained in the inner cavity of the bearing. If the retaining ring is not installed properly during the assembly process, causing the retaining ring to tilt, or if multiple retaining rings are assembled at the same time, it is easy for the retaining ring to squeeze the space in the inner cavity of the bearing, thereby squeezing the needle rollers and causing damage, affecting the processing quality of the bearing.

The number of bearings to be measured is huge, and calculations are required to determine whether the size of each bearing after the retaining ring is assembled meets the use requirements, which leads to a large workload and easily causes inaccurate inspection data.

[0045] This embodiment discloses a detection device, such as Figure 2 and Figure 3 As shown, the detection device includes a detection module 1 and an output module, and the output module drives the detection module 1 to reciprocate between a first position and a second position along a height direction;

[0046] The detection module 1 comprises a main body 11 and a plurality of connecting parts 12, wherein the middle of the main body 11 comprises a first central hole 111 extending in the height direction, the plurality of connecting parts 12 are respectively connected to the outer side surfaces of the main body 11, the elastic components 13 are respectively arranged on the connecting parts 12, and the displacement sensors are respectively arranged on the connecting parts 12;

[0047] The output shaft of the output module passes through the first central hole 111 and is movably connected to the main body 11 .

[0048] Furthermore, the output module also has a connecting piece, and the output shaft of the output module is provided with a fitting portion, and the fitting portion has a step formed on the side where the output module is located, and the end of the fitting portion away from the side where the output module is located passes through the first center hole 111 and is detachably fixedly connected to the connecting piece, and the step is located at the end of the main body 11 away from the side where the connecting piece is located, and the connecting piece limits the main body 11 to the fitting portion.

[0049] Furthermore, a receiving groove is concavely provided at the bottom of each connecting portion 12 along the height direction;

[0050] The elastic component 13 includes a support member 131 and an elastic member, one end of the elastic member is fixed to the bottom of the container, and the other end of the elastic member is fixed to the top of the support member 131, and the bottom of the support member 131 passes through the open end of the container and is exposed outside the container;

[0051] The detection module 1 further includes a plurality of pressure sensors, and each of the pressure sensors is disposed on the elastic component 13 in a one-to-one correspondence.

[0052] In this embodiment, the detection device has a base, a bracket is fixed on the base along the height direction, and the output module is fixed on the bracket, so that the output axis of the output module extends downward along the height direction. The output module drives the detection module 1 to reciprocate between the first position and the second position along the height direction.

[0053] The base is provided with a mounting platform, on which the assembled bearing can be placed, so that the retaining ring of the bearing is located directly below the detection module 1. In the present application, the output module can be a cylinder or an electric cylinder, or other implementable structures, and the present application is not limited thereto.

[0054] Furthermore, the detection module 1 has a main body 11 and three connecting parts 12 extending outward along the periphery of the main body 11. In the present application, the three connecting parts 12 are arranged at equal intervals along the periphery of the main body 11. The number of the connecting parts 12 is not limited to this and can be reasonably arranged according to the actual detection environment. For example, four connecting parts 12 or more than four connecting parts 12 can be set. In the present application, the middle part of the main body 11 extends along the height direction with a first center hole 111, and the first center hole 111 is set through the main body to facilitate the active connection between the main body 11 and the output shaft of the output module. Each connecting part 12 is provided with a displacement sensor for receiving a feedback signal of the position movement of each connecting part 12.

[0055] Furthermore, the detection device also includes a connecting piece. Wherein, a fitting portion (not shown in the drawings) is provided at the end where the output shaft of the output module is located, and the fitting portion is arranged away from the side where the main body of the output module is located, and a step is formed on the fitting portion close to the side where the output module is located, and the step forms a step surface toward the end away from the side where the output module is located. In the present application, the fitting portion of the output shaft of the output module is partially connected to the connecting piece in a detachable manner through the first center hole 111, so that the main body is limited on the bearing sleeve and is located between the step surface and the connecting piece. In the present application, there is a gap between the fitting portion and the first center hole 111, so that the main body can shake relative to the fitting portion, thereby facilitating the completion of error-proofing detection of the bearing retaining ring. Wherein, the connecting piece can be a nut, and the outer periphery of the fitting portion is provided with threads, so that the connecting piece is threadedly connected to the fitting portion.

[0056] Furthermore, a receiving groove is recessed at the bottom of each connecting portion 12 along the height direction, so that a portion of the elastic component 13 is located in the receiving groove, and the remaining portion of the elastic component 13 is exposed outside the receiving groove, so that when the detection device needs to perform measurement, the output module can be driven so that the output shaft of the output module drives the detection module 1 to move downward along the height direction, thereby forcing the elastic components 13 on each connecting portion 12 to abut against the retaining ring of the bearing on the mounting platform to achieve detection.

[0057] Furthermore, the elastic component 13 includes a support member 131 and an elastic member, one end of the elastic member is fixed to the bottom of the receiving groove, and the other end of the elastic member is fixed to the top of the support member 131, so that the bottom of the support member 131 passes through the open end of the receiving groove and is exposed outside the receiving groove. Among them, the detection device also includes three pressure sensors, each of which is correspondingly arranged on one of the elastic members. In the present application, the elastic member can be an elastic ball or a compression spring, and the support member 131 can be a pin or other implementable components, and the present application is not limited to this.

[0058] In this embodiment, the detection device further includes a system processing module to calculate and process feedback signals obtained by the pressure sensor and the displacement sensor to improve the working efficiency of the detection device.

[0059] This embodiment also discloses a bearing retaining ring error prevention detection method, such as Figure 1 As shown, the following steps are included:

[0060] Obtain at least three sets of pressure sensing data sets of elastic components, wherein the pressure sensing data sets include at least three pressure sensing data sets; in the present application, when the output module drives the detection module to move downward in the height direction, the support members on the multiple connection parts of the detection module move downward and abut against the retaining ring of the bearing placed on the mounting platform, and the support members of each elastic component abut against different positions of the retaining ring, and the output module continues to drive the detection module to move downward, thereby forcing the elastic component to contract, so that the elastic component is in a compressed state, at which time the pressure sensor located on the elastic component will detect a feedback signal, thereby collecting the pressure sensing data of the elastic component. The pressure sensing data set preferably has three pressure sensing data sets.

[0061] The running state of the detection module is obtained according to the pressure sensing data set, and the detection mode is entered according to the running state; wherein, the safety pressure threshold of the elastic component is obtained, and if there is at least one pressure sensing data greater than or equal to the safety pressure threshold in the pressure sensing data set, the running state of the detection module enters the detection mode. In the present application, the elastic member in each group of elastic components has a safety pressure threshold, and the safety pressure threshold is the state in which the elastic member can be restored to the state before elastic deformation after being in a compressed state. wherein, in the process of the detection module moving downward, when at least one pressure sensing data reaches or exceeds the safety pressure threshold, the output module can be controlled to stop driving, thereby realizing that the detection module can enter a pause state from a running state, and thus enter the detection mode.

[0062] Acquire a monitoring displacement data set of at least three displacement sensors in operation, wherein the monitoring displacement data set includes at least three monitoring displacement data; in the present application, after entering the detection mode, the three displacement sensors can be used to obtain the distance feedback signals of the downward movement of the three connecting parts, so as to obtain the monitoring displacement data of each connecting part, and the monitoring displacement data is the actual distance after the elastic component of the detection module stops moving against the retaining ring.

[0063] Obtain the standard displacement data of the detection module in the detection mode; in this application, a standard bearing can be placed on the mounting platform, and after the detection module is driven downward by the output module, the downward drive can be stopped when there is at least one pressure sensing data in the pressure sensing data set that is greater than or equal to the safety pressure threshold. At this time, the feedback signal obtained by each displacement sensor is the standard displacement data. Among them, under the detection of the standard bearing, the three pressure sensing data are equal or within the allowable error range; the three monitoring displacement data sets are also equal or within the allowable error range, and the average value of the three monitoring displacement data sets is the standard displacement data.

[0064] A first error data set is obtained based on the monitoring displacement data set and the standard displacement data; in the present application, three displacement error data can be obtained by measuring the difference between the three monitoring displacement data obtained from the data of the retaining ring of the bearing after production and the standard displacement data, that is, the first error data set is obtained.

[0065] The first maximum error value is obtained according to the first error data set. If the first maximum error value is greater than the required threshold, an alarm signal is given and the detection is terminated; in the present application, it can be determined whether the maximum displacement error data (i.e., the first maximum error value) among the three displacement error data is greater than the required threshold; if so, the size of the retaining ring of the detected bearing does not meet the use requirements. The reason for this is that the tilt of the retaining ring forces the three monitoring displacement data to be abnormal, or the three monitoring displacement data are forced to be abnormal after two or more retaining rings are pressed. Therefore, the detection device gives an alarm signal to remind the detection personnel that the product size does not meet the use requirements. At the same time, the detection of the bearing is terminated so that the next bearing can be detected quickly. Among them, the required threshold is the maximum value allowed for the size error of the retaining ring after the crimping is completed.

[0066] In some embodiments, the detection method further comprises: if the first maximum error value is less than or equal to a required threshold, obtaining an average pressure data value of the pressure sensing data set;

[0067] Obtaining a second error data set based on the pressure sensing data set and the average pressure data value;

[0068] A second maximum error value is obtained according to the second error data set. If the second maximum error value is greater than the error pressure threshold, an alarm signal is given and the detection is terminated.

[0069] In this embodiment, when the first maximum error value is less than or equal to the required threshold, the detection device may appear at this time; when a single bearing retaining ring is pressed and tilted, causing the detection module to move downward, the pressure sensing data obtained by each pressure sensor caused by the downward movement of each connecting part is different, causing each displacement sensor to obtain the same monitoring displacement data. Therefore, it is necessary to review the three pressure sensing data of the pressure sensing data set, and the average pressure data value of the three pressure sensing data can be obtained through the system processing module, and the three error values ​​between the three pressure sensing data and the average pressure data value are obtained, that is, the second error data set is obtained, and then the maximum error value is selected to be greater than the error pressure threshold. If so, the size of the retaining ring of the detected bearing does not meet the use requirements due to the assembly tilt.

[0070] In some embodiments, the detection method further includes: if the second maximum error value is less than the error pressure threshold, the detection ends.

[0071] In this embodiment, when the second maximum error value is smaller than the error pressure threshold, the size of the retaining ring of the bearing assembly meets the use requirements.

[0072] This embodiment also discloses a bearing retaining ring error prevention detection method, comprising the following steps:

[0073] Acquire at least three sets of pressure sensing data sets of elastic components, wherein the pressure sensing data sets include at least three pressure sensing data;

[0074] Acquire the operating status of the detection module according to the pressure sensing data set, and enter the detection mode according to the operating status;

[0075] Acquire a monitoring displacement data set of at least three displacement sensors in an operating state, wherein the monitoring displacement data set includes at least three monitoring displacement data;

[0076] Obtain standard displacement data of the detection module in the detection mode;

[0077] Obtaining a first error data set according to the monitoring displacement data set and the standard displacement data;

[0078] A first maximum error value is obtained according to the first error data set. If the first maximum error value is greater than the required threshold, the average pressure data value of the pressure sensing data set is obtained. In this application, if the first maximum error value is greater than the required threshold, the size of the retaining ring of the bearing assembly does not meet the use requirements, that is, it is necessary to detect what is wrong with the retaining ring of the bearing assembly. A preliminary judgment can be made based on the data of the pressure sensing data set.

[0079] Obtaining a second error data set based on the pressure sensing data set and the average pressure data value;

[0080] A second maximum error value is obtained according to the second error data set, and if the second maximum error value is greater than the error pressure threshold, a first alarm signal is given and the detection is terminated. In the present application, when the second maximum error value is greater than the error pressure threshold, the retaining ring of the bearing assembly is in a tilted state, so that the size of the retaining ring of the bearing assembly does not meet the use requirements.

[0081] Furthermore, the detection method further comprises: if the second maximum error value is less than or equal to the error pressure threshold, a second alarm signal is given and the detection is terminated. In the present application, when the second maximum error value is less than or equal to the error pressure threshold, the bearing is equipped with two or more retaining rings, so that the size of the retaining rings equipped with the bearing does not meet the use requirements.

[0082] In summary, through the technical solution of the present invention, the pressure sensor data and the feedback signals of multiple displacement sensors are combined for judgment, so that the axial dimension parameters of the same type of bearings after the retaining rings are assembled can be quickly measured and the unqualified products can be screened out, which has the advantages of high measurement efficiency and good accuracy.
