Description

Technical Field

[0001] The utility model relates to the field of bearing detection, in particular to an automatic detection system for heavy balls used in bearing assembly. Background Art

[0002] Certain types of bearings, such as crossed roller bearings, have unique internal structures that require alternating spacers and balls to maintain stability and performance. The spacers maintain the spacing between the balls, preventing them from rubbing against each other or tilting, while the balls roll and carry the load.

[0003] Alternating spacers and balls optimizes bearing performance. The spacers distribute loads, reduce vibration, and protect against contamination, while the balls increase friction and wear resistance. This combination enables the bearing to withstand greater loads, operate more smoothly, and be quieter.

[0004] However, during the installation of the spacers and balls, various situations (such as improper installation sequence, improper installation force causing the balls to shift, etc.) may result in the absence of a spacer between two adjacent balls, a phenomenon known as heavy ball phenomenon. This phenomenon can lead to a high bearing failure rate, including uneven load distribution, increased friction and wear, shortened bearing life, decreased operational stability, and increased failure risk. Therefore, during the installation and maintenance of bearings, ensure that the spacers and balls are correctly installed and configured to ensure the normal operation and long-term stability of the bearings.

[0005] In the past, heavy ball detection relied entirely on human visual identification, which could not guarantee 100% accuracy. After a heavy ball occurs, the bearing will directly cause abnormal noise after being assembled into the main engine, resulting in a sharp increase in negative quality feedback.

[0006] Therefore, there is a need for an automatic heavy ball detection system for bearing assembly that can automatically detect whether there is a heavy ball, accurately detect the result, and reduce the bearing failure rate. Utility Model Content

[0007] In order to solve the defects of the existing heavy ball phenomenon during bearing installation, inaccurate detection of heavy balls by naked eyes, and high bearing failure rate, the utility model provides an automatic heavy ball detection system for bearing assembly, which can automatically detect whether there is a heavy ball, has accurate detection results, and reduces the bearing failure rate.

[0008] The utility model describes an automatic detection system for heavy balls used in bearing assembly, wherein the bearing includes an inner ring, an outer ring, a steel ball and an isolation block. The automatic detection system for heavy balls includes a visual sensor and a visual signal processing unit. The output end of the visual sensor is communicatively connected to the visual signal processing unit. The visual sensor is used to identify the steel ball and the isolation block. The visual signal processing unit can determine the current relative relationship between the steel ball and the isolation block based on the signal provided by the visual sensor, and issue an alarm message when there is a continuous setting of the steel ball or the isolation block.

[0009] Furthermore: it also includes an alarm, the output end of the visual signal processing unit is communicatively connected to the input end of the alarm, the visual signal processing unit determines the current relative relationship between the steel ball and the isolation block based on the signal provided by the visual sensor, and triggers the alarm when the steel ball or the isolation block is continuously set, and the alarm sounds an alarm.

[0010] Furthermore: the alarm is a buzzer alarm, a light alarm and / or a vibration alarm.

[0011] Furthermore: it also includes a supporting component, which is used to support the inner ring and outer ring of the bearing.

[0012] Furthermore: the supporting component includes a chopping board and a sling. When the steel ball and the isolation block are installed with the inner ring stationary and the outer ring rotating, the chopping board is used to support the inner ring, and the sling is used to lift the outer ring so that the outer ring can rotate around the inner ring; when the steel ball and the isolation block are installed with the outer ring stationary and the inner ring rotating, the chopping board is used to support the outer ring, and the sling is used to lift the inner ring so that the inner ring can rotate inside the outer ring.

[0013] Furthermore: it also includes a magnetic base, and the visual sensor is adsorbed on the bearing to be detected through the magnetic base, so that the visual sensor is facing the gap between the inner ring and the outer ring.

[0015] Furthermore: any isolation block is set as a reference block, the reference block is color A, the remaining isolation blocks are color B, and the steel ball is color C, wherein color A, color B and color C are all different colors.

[0016] Furthermore: the visual sensor is a smart camera, an industrial camera or an RGB camera.

[0017] The beneficial effects of the utility model are:

The scope of protection of the present invention should be based on the scope of protection of the claims. The embodiments of the present invention are described in detail below. In order to facilitate the description of the present invention and simplify the description, the technical terms used in the specification of the present invention should be interpreted broadly, including but not limited to conventional replacement schemes not mentioned in this application, as well as direct implementation methods and indirect implementation methods.

[0028] Example 1

[0029] Combine Figure 1-Figure 4 This embodiment describes a heavy ball automatic detection system for bearing assembly, as shown in FIG. Figure 1As shown, the bearing includes an inner ring 11, an outer ring 12, a steel ball 13 and an isolation block 14. The heavy ball automatic detection system includes a visual sensor 2 and a visual signal processing unit 6. The output end of the visual sensor 2 is connected to the visual signal processing unit 6 for communication. The visual sensor 2 is used to identify the steel ball 13 and the isolation block 14. The visual signal processing unit 6 can determine the current relative relationship between the steel ball 13 and the isolation block 14 based on the signal provided by the visual sensor 2, and issue an alarm message when there is a continuous setting of the steel ball 13 or the isolation block 14. The visual signal processing unit 6 detects the visual signal of the visual sensor 2 in real time, as shown in FIG. Figure 2 As shown, the visual signal shows the relative relationship between the steel balls 13 and the isolation blocks 14, including that there is an isolation block 14 between every two steel balls 13, and there is a steel ball 13 between every two isolation blocks 14. At this time, it means that there is no heavy ball phenomenon in the bearing 1. If there is no isolation block 14 between the two steel balls 13, or there is no steel ball 13 between the two isolation blocks 14, it means that there is a heavy ball phenomenon in the current bearing 1, which is regarded as a fault. At this time, the visual signal processing unit 6 issues an alarm message.

[0030] The heavy ball automatic detection system also includes an alarm 3. The output end of the visual signal processing unit 6 is communicatively connected to the input end of the alarm 3. The visual signal processing unit 6 determines the relative relationship between the current steel ball 13 and the isolation block 14 based on the signal provided by the visual sensor 2. When the steel ball 13 or the isolation block 14 is continuously set, the alarm 3 is triggered, and the alarm 3 issues an alarm. After receiving the alarm information from the visual signal processing unit 6, the alarm 3 issues an alarm according to the alarm type of the alarm 3. For example, if the alarm 3 is a buzzer alarm, the buzzer alarm issues a buzzing sound warning; if the alarm 3 is a light alarm, the light alarm lights up to warn; if the alarm 3 is a vibration alarm, the vibration alarm issues a vibration warning. Other alarms that can realize alarms can be used. In addition, the above-mentioned different types of alarms 3 can be used in combination of multiple types.

[0031] The heavy ball automatic detection system further includes a support component 4, which is used to support the inner ring 11 and outer ring 12 of the bearing 1. The support component 4 includes a cutting board 41 and a sling 42. When the steel ball 13 and the isolation block 14 are installed in a manner such that the inner ring 11 is stationary and the outer ring 12 is rotated, the cutting board 41 is used to support the inner ring 11, and the sling 42 is used to suspend the outer ring 12 so that the outer ring 12 can rotate around the inner ring 11. Figure 3As shown, due to the height difference between the inner and outer rings of the bearing 1, when the bearing 1 is installed, the inner ring 11 is placed flat on the chopping board, and the inner ring 11 is in direct contact with the chopping board 41. The outer ring 12 is lifted by the sling 42 and three steel balls 13 are inserted into the raceway to play a supporting role. The outer ring 12 can then rotate relative to the inner ring 11. Since the friction starting torque of the bearing is very small, the outer ring can be rotated by pushing it by hand.

[0032] When the steel balls 13 and the isolation blocks 14 are installed in a manner such that the outer ring 12 is fixed and the inner ring 11 rotates, the chopping board 41 is used to support the outer ring 12, and the sling 42 is used to suspend the inner ring 11 so that the inner ring 11 can rotate within the outer ring 12. Figure 4 As shown, when the bearing 1 is installed, the outer ring 12 is placed flat on the chopping board 41, and the outer ring 12 is in direct contact with the chopping board 41. The inner ring 11 is lifted by the sling 42 and three steel balls are inserted into the raceway to play a supporting role. The inner ring 11 can be rotated relative to the outer ring 12 by pushing it by hand.

[0033] The heavy ball automatic detection system further includes a magnetic base 5 , through which the visual sensor 2 is adsorbed on the bearing 1 to be detected, so that the visual sensor 2 faces the gap between the inner ring 11 and the outer ring 12 .

[0034] When the steel ball and the isolation block 14 are installed by keeping the inner ring 11 stationary and the outer ring 12 rotating, the magnetic base 5 is adsorbed on the inner ring 11; when the steel ball and the isolation block 14 are installed by keeping the outer ring 12 stationary and the inner ring 11 rotating, the magnetic base 5 is adsorbed on the outer ring 12.

[0035] Any isolation block 14 is set as a reference block 141, the reference block 141 is color A, the other isolation blocks 14 are color B, and the steel ball 13 is color C, wherein colors A, B, and C are all different colors. For example, if color C is silver, then the steel ball 13 remains silver, if color B is white, then the nylon isolation block 14 remains white, and if color A is red, then the nylon reference block 141 is painted red, to distinguish the three colors, highlight the color difference of the three colors, and increase the recognition of the visual sensor 2. For example, the steel ball 13 can also be electroplated into other colors, such as black, that is, color C is black, the nylon isolation block 14 is painted yellow, that is, color B is yellow, and the reference block 141 is painted green, that is, color A is green, also to highlight the color difference of the three colors. As long as the three colors can meet the recognition requirements of the visual sensor 2, it is sufficient.

[0036] The visual sensor 2 is a smart camera, an industrial camera or an RGB camera. If an RGB camera is used, the color difference of the three colors can be accurately determined to the RGB level, so as long as the three colors ABC are different, it will be sufficient.

[0037] Example 2

[0038] This embodiment is described in conjunction with Example 1. The overall working principle of the heavy ball automatic detection system for bearing assembly disclosed in this embodiment is as follows:

[0039] The visual signal processing unit 6 has pre-set program rules, which is its own function and only requires simple configuration. This is the existing technology. The visual signal captured by the visual sensor 2 is automatically processed and the alarm 3 is controlled according to the rules to realize the alarm.

[0040] For example, the program rules are set as follows: the steel ball 13 is a spherical metallic color, and the isolation block 14 is a square white color. The rules require that the spherical metallic color and the square white color should appear alternately. When the spherical metallic color or the square white color are repeatedly recognized, it means that a heavy ball or a heavy block has occurred, and the alarm 3 repeatedly alarms at intervals. Any isolation block 14 is set as a reference block 141 and painted red. The visual sensor 2 begins the recognition process when it recognizes the red reference block 141 and stops the recognition process when it recognizes the repeated red reference block 141. In other words, at this point, one cycle of detection has been completed, and the alarm 3 will not repeat and continuously alarm. The alarm signal at this time is set to a different alarm mode from the alarm signal for detecting heavy balls or heavy blocks, and the detection is now complete.

[0041] Before the test begins, a red-painted reference block 141 is manually installed, and a visual sensor 2 with a magnetic base 5 is installed. The identification position is the assembly gap of the inner / outer ring of the bearing 1, and the heavy ball test can be performed while the steel ball 13 and the isolation block 14 are installed.
