[0024] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] It should be pointed out that unless otherwise specified, all technical and scientific terms used in the present application have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0026] In the present invention, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the present invention.

[0027] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] In order to solve the problems of low efficiency and accuracy of manual detection of bearings in the prior art, the present invention provides a bearing detection and lubrication device and a detection system. Among them, the following detection system includes the following bearing detection and lubrication device.

[0029] Such as Figure 1 And Figure 3As shown in the figure, the bearing detection and lubrication device includes a workbench 10, a limit component 20, a first driving component 30, a rotating component 40, and a detection and lubrication component 50. The limit component 20 is disposed on the workbench 10 and is used to limit the outer ring of the bearing 100. The first driving component 30 is arranged on the workbench 10. The rotating component 40 is rotatably arranged on the workbench 10. One end of the rotating component 40 is used to abut against the inner ring of the bearing 100, and the other end is drivingly connected to the first driving component 30 and is used to drive the inner ring of the bearing 100 to rotate under the drive of the first driving component 30. The detection and lubrication component 50 is arranged on the workbench 10 to detect and lubricate the component 50 and is correspondingly located above the rotating component 40. The detection and lubrication component 50 is used to detect the end face runout accuracy of the bearing 100 and / or lubricate the bearing 100.

[0030] By limiting the outer ring of the bearing 100 through the limit component 20 and the way that the rotating component 40 abuts against the inner ring of the bearing 100, the first driving component 30 drives the rotating component 40 to rotate on the workbench 10, so as to realize the relative rotation of the inner and outer rings of the bearing 100. At this time, the detection and lubrication component 50 can abut against the end face of the bearing 100 to detect the runout accuracy of the end face of the bearing 100, or inject lubricating oil between the inner and outer rings of the bearing 100. Compared with the manual detection method, the detection of this application is more accurate and can inject lubricating oil in real time, thereby improving the accuracy of detection. At the same time, this application can continuously perform detection, thereby improving the detection efficiency.

[0031] As Figure 3 shown in the figure, the rotating component 40 includes a main body part 41 and a movable part 42. One end of the main body part 41 is drivingly connected to the first driving component 30. The movable part 42 is arranged at the other end of the main body part 41. The movable part 42 is telescopically arranged and is used to abut against the inner ring of the bearing 100.

[0032] Specifically, one end of the main body part 41 is sleeved on the pivot shaft on the top surface of the workbench 10 or partially extends into the workbench. The movable part 42 is telescopically arranged along the radial direction of the workbench 10 at the other end of the main body part 41. When the inner ring size of the bearing 100 is small, the movable part 42 extends a short distance to abut against the inner ring. When the inner ring size of the bearing 100 is large, the distance between the movable part 42 and the center line of the main body part 41 is greater than the diameter of the main body part 41. Optionally, the abutting surface of the movable part 42 for abutting against the inner ring of the bearing 100 has an anti-slip structure, and the anti-slip structure can prevent the movable part 42 from sliding relative to the inner ring of the bearing 100 when lubricating oil drips onto the inner ring of the bearing 100.

[0033] In this embodiment, the rotating component 40 is a multi-claw jaw structure, and the movable part 42 is a multi-claw jaw sleeve.

[0034] Specifically, the main body 41 is an electric gripper, and there are multiple movable parts 42. The multiple movable parts 42 are arranged on the top surface of the main body 41. By abutting against the inner ring of the bearing 100 through the multiple movable parts 42, the connection effect between the movable part 42 and the inner ring of the bearing 100 can be improved. The movable part 42 includes a supporting plate and an abutting column. The abutting column is arranged on the supporting plate. When in use, the bearing 100 is placed horizontally, the supporting plate abuts against the bottom surface of the inner ring at this time, and the abutting of the abutting column against the inner ring not only realizes the effect of the main body 41 driving the inner ring to rotate but also prevents the bearing 100 from falling off downward.

[0035] As Figures 1 to 2 shown in the figure, the limiting component 20 includes a mounting seat 21, a limiting member 22, and a second driving member 23. The mounting seat 21 is arranged on the workbench 10. There are two limiting members 22, and the two limiting members 22 are arranged at intervals and are both movably arranged on the mounting seat 21 for clamping and limiting the bearing 100. The second driving member 23 is arranged on the mounting seat 21 and is drivingly connected to the limiting member 22 for driving the two limiting members 22 to approach or separate from each other.

[0036] Specifically, the mounting seat 21 is connected to the workbench 10 by bolts. The two limiting members 22 are arranged at both ends of the mounting seat 21, and the second driving member 23 is arranged at one end of the mounting seat 21. By driving the two limiting members 22 to approach or separate from each other through the second driving member 23, the outer ring of the bearing 100 can be clamped or loosened.

[0037] As Figure 2 shown in the figure, the limiting component 20 further includes two first transmission wheels 24 and a first transmission belt 25. The two first transmission wheels 24 are arranged at intervals and are rotatably arranged on the mounting seat 21. The first transmission belt 25 is sleeved on the two first transmission wheels 24. The two limiting members 22 are respectively connected to the two sides of the first transmission belt 25 relative to the two first transmission wheels 24, and the second driving member 23 is drivingly connected to the first transmission belt 25.

[0038] Specifically, the two first transmission wheels 24 are respectively arranged at both ends of the mounting seat 21. The first transmission belt 25 is sleeved on the two first transmission wheels 24. The first transmission belt 25 is a belt. Optionally, multiple anti-slip protrusions are arranged on the first transmission wheel 24 to increase the friction between the first transmission wheel 24 and the first transmission belt 25 and avoid relative sliding between the two. The two limiting members 22 are arranged on two opposite sections of the first transmission belt 25. The two limiting members 22 are arranged at intervals and the distance between them is greater than the diameter of the bearing 100.

[0039] In this embodiment, the second driving member 23 is a cylinder. The second driving member 23 is connected to one end of the first transmission belt 25. By the telescopic movement of the second driving member 23, the first transmission belt 25 can be moved, and then the two limiting members 22 are driven to approach each other to clamp the bearing 100.

[0040] In this embodiment, a connecting member 90 is provided on the first transmission belt 25, and the output end of the second driving member 23 is connected to the connecting member 90. Optionally, the connecting member 90 is provided on one of the two limiting members 22 that is closer to the second driving member 23.

[0041] As Figure 2 shown, the two limiting members 22 are respectively provided with limiting notches 221 adapted to the bearing 100, and the two corresponding limiting notches 221 form a limiting space.

[0042] Specifically, the radian of the limiting notch 221 is equal to or slightly larger than the radian of the outer ring. During detection, the outer ring of the bearing 100 is exactly within the limiting space formed by the two limiting notches 221. Optionally, the cross-section of the limiting space is also a circle and is adapted to the outer ring.

[0043] As Figure 2 shown, the limiting assembly 20 further includes a guide rail 26. The guide rail 26 is provided on the mounting base 21, and the limiting member 22 is slidably connected to the guide rail 26.

[0044] Specifically, the length of the guide rail 26 is adapted to the length of the mounting base 21, and the two first transmission wheels 24 are located at both ends of the mounting base 21 in the length direction. There are two guide rails 26, and the two guide rails 26 are provided on both sides of the first transmission belt 25. The limiting member 22 is provided with a structure adapted to the guide rail 26. Thus, when the second driving member 23 drives the first transmission belt 25 to move, the limiting member 22 slides along the guide rail 26. At this time, the bottom of the limiting member 22 has two support points, which facilitates the movement of the limiting member 22. At the same time, since the first transmission belt 25 is a belt, setting the guide rail 26 can prevent a large angle from occurring between the limiting member 22 and the outer ring of the bearing 100, resulting in a decrease or even failure of the limiting effect.

[0045] As Figure 1 and Figure 3 shown, the bearing detection and lubrication device further includes a second transmission wheel 60 and a second transmission belt 70. The second transmission wheel 60 is sleeved on the output end of the first driving member 30. The second transmission belt 70 is sleeved on the second transmission wheel 60 and the other end of the rotating assembly 40.

[0046] Specifically, the second transmission wheel 60 is provided with an anti-slip structure to increase the friction with the second transmission belt 70. The bearing detection and lubrication device further includes a plurality of synchronous wheels 110. The plurality of synchronous wheels 110 are respectively located on both sides of the second transmission wheel 60, and the synchronous wheels 110 are spaced apart from the second transmission wheel 60. By cooperating with the synchronous wheels 110 and the second transmission wheel 60, the tension of the second transmission belt 70 is increased, so that the first driving member 30 can better drive the rotating assembly 40 to rotate, and then drive the inner ring to rotate.

[0047] AsFigure 1 and Figure 4 As shown in Figure 4 , the detection and lubrication assembly 50 includes a detection and lubrication member 51 and a third driving member 52. The detection and lubrication member 51 is located above the rotating assembly 40. The third driving member 52 is drivingly connected to the detection and lubrication member 51. The third driving member 52 drives the end of the detection and lubrication member 51 to approach or move away from the bearing 100, so that the end of the detection and lubrication member 51 abuts against the end face of the bearing 100 and / or the detection and lubrication member 51 injects lubricating oil into the bearing 100.

[0048] Specifically, the bearing detection and lubrication device further includes a fixing base 80. One end of the fixing base 80 is detachably connected to the workbench 10. The height of the fixing base 80 is greater than the height of the rotating assembly 40. The third driving member 52 is disposed at the other end of the fixing base 80. The detection and lubrication member 51 is connected to the third driving member 52. The third driving member 52 drives the detection and lubrication member 51 to move downward to detect the end face runout accuracy of the bearing 100, or the detection and lubrication member 51 is moved close to the inner ring, and then the detection and lubrication member 51 injects lubricating oil. Optionally, the third driving member 52 is a cylinder.

[0049] In this embodiment, both the rotating assembly 40 and the detection and lubrication assembly 50 are two. The two rotating assemblies 40 are disposed on both sides of the limiting assembly 20. Both the two rotating assemblies 40 are drivingly connected to the first driving member 30.

[0050] Specifically, the two detection and lubrication assemblies 50 and the two rotating assemblies 40 are arranged in one-to-one correspondence. The first driving member 30 drives the second transmission belt 70 to move, thereby driving the two rotating assemblies 40 to rotate, realizing single-machine double-station detection and greatly improving the detection efficiency. Correspondingly, both ends of the limiting member 22 are provided with limiting notches 221. The two limiting members 22 can limit the outer rings of the two bearings 100. Of course, the rotating assembly 40 can also be more.

[0051] The present application also provides a detection system. The detection system includes the above-mentioned bearing detection and lubrication device and a robotic arm. The robotic arm is arranged corresponding to the bearing detection and lubrication device.

[0052] Specifically, the robotic arm is one or two. When the robotic arm is one, one robotic arm sequentially places two bearings 100 on the bearing detection and lubrication device. After the two bearings 100 are placed, the detection starts simultaneously. When the robotic arm is two, the speed of placing the bearings 100 can be increased, thereby improving the automation degree of the detection system.

[0053] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: By providing a bearing detection and lubrication device including a workbench 10, a limiting component 20, a first driving member 30, a rotating component 40, and a detection and lubrication component 50, the limiting component 20 is disposed on the workbench 10 and is used to limit the outer ring of the bearing 100. The first driving member 30 is arranged on the workbench 10. The rotating component 40 is rotatably arranged on the workbench 10. One end of the rotating component 40 is used to abut against the inner ring of the bearing 100, and the other end is drivingly connected to the first driving member 30 and is used to drive the inner ring of the bearing 100 to rotate under the drive of the first driving member 30. The detection and lubrication component 50 is arranged on the workbench 10 to detect the lubrication component 50 and is correspondingly located above the rotating component 40. The detection and lubrication component 50 is used to detect the end face runout accuracy of the bearing 100 and / or lubricate the bearing 100. By limiting the outer ring of the bearing 100 through the limiting component 20 and abutting the rotating component 40 against the inner ring of the bearing 100, the first driving member 30 drives the rotating component 40 to rotate on the workbench 10, thereby realizing the relative rotation of the inner and outer rings of the bearing 100. At this time, the detection and lubrication component 50 can abut against the end face of the bearing 100 to detect the runout accuracy of the end face of the bearing 100, or inject lubricating oil between the inner and outer rings of the bearing 100. Compared with the manual detection method, the detection of the present application is more accurate and can inject lubricating oil in real time, thereby improving the accuracy of detection. At the same time, the present application can continuously perform detection, thereby improving the detection efficiency.
