[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] As mentioned in the background section of this application, research has found that the common existing inspection method is to place the bearing flat on the inspection table for visual inspection. However, this inspection method has certain defects. It cannot effectively combine the flat inspection, vertical inspection and rotation inspection of the bearing 13. The inspection process is not comprehensive enough and the inspection results are not accurate enough.
[0026] To address the aforementioned deficiencies, this application discloses a testing device for the outer ring of an outer spherical bearing, which effectively combines the flat-lay testing, vertical testing, and rotation testing of the bearing 13, making the testing process more comprehensive and thereby improving the accuracy of the testing results.
[0027] The following will describe in detail, with reference to the accompanying drawings, how the solution of this application solves the above-mentioned technical problems.
[0028] Please see Figures 1-5 In this embodiment of the present invention, a testing device for the outer ring of an outer spherical bearing includes a worktable 1. A vertical plate 2 is fixedly connected to one side of the top surface of the worktable 1, and a horizontal plate 3 is fixedly connected to the top side of the vertical plate 2. A movable visual inspection mechanism is provided on the bottom surface of the horizontal plate 3. A rotating groove 7 is provided near the middle of the top surface of the worktable 1, and an L-shaped rotating plate 8 is rotatably connected inside the rotating groove 7. Multiple fixing parts are provided along the length of the top surface of the L-shaped rotating plate 8, and a driving part for driving the fixing parts to rotate is provided inside the L-shaped rotating plate 8. A calibration part is provided on the side of the vertical plate 2. This application, through the setting of the L-shaped rotating plate 8, fixing parts, driving part and calibration part, can effectively combine the flat-lay inspection, vertical inspection and rotation inspection of the bearing 13, making the inspection process more comprehensive and thus improving the accuracy of the inspection results.
[0029] In this embodiment, the fixing component specifically includes: a positioning screw 16 rotatably connected to the top surface of the L-shaped rotating plate 8; a ring 18 fixedly connected to the bottom end of the outer side of the positioning screw 16; and a positioning nut 19 threadedly connected to the top end of the outer side of the positioning screw 16. The fixing component can fix the bearing 13 to be tested for subsequent testing.
[0030] In this embodiment, the driving component specifically includes: a driving cavity 14 formed inside the L-shaped rotating plate 8; multiple evenly distributed pulleys 15 are rotatably connected inside the driving cavity 14; each pulley 15 corresponds to a positioning screw 16 of a fixing component and is fixedly connected via a connecting rod 17; a transmission belt 25 is provided between two adjacent pulleys 15; a driving motor 11 is fixedly connected to the bottom end face of the L-shaped rotating plate 8; and the output shaft of the driving motor 11 passes through the driving cavity 14 and is fixedly connected to one of the pulleys 15. A placement groove 10 matching the driving motor 11 is provided on the other side of the top surface of the worktable 1. The driving component can drive each bearing 13 to rotate, thereby performing comprehensive testing on the bearings 13.
[0031] In this embodiment, calibration strips 12 are embedded on both sides of the top surface of the L-shaped rotating plate 8. The calibration strips 12 can serve as references when testing the bearing 13.
[0032] In this embodiment, the calibration component specifically includes: two cylinders 20 arranged side-by-side inside the side wall of the vertical plate 2. A diaphragm 21 is fixedly connected to the output shaft of each cylinder 20, and a support rod 22 is fixedly connected to the side of the diaphragm 21 away from the cylinder 20. A round head 23 is fixedly connected to one end of each support rod 22, and a rope 24 is provided between the round heads 23 of the two support rods 22, and the rope 24 is always kept taut. The calibration component can provide a reference point for the bearing 13 during vertical testing.
[0033] In this embodiment, the mobile visual inspection mechanism specifically includes: a linear guide rail 4 fixed to the bottom surface of the horizontal plate 3, a linear motor 5 movably connected to the outer side of the linear guide rail 4, and a camera 6 fixedly connected to the bottom surface of the linear motor 5. The mobile visual inspection mechanism can adjust the position of the camera 6 as needed to perform visual inspection.
[0034] In this embodiment, a rotary motor 9 is embedded in the inner walls of both sides of the rotating groove 7, and the output shaft of the rotary motor 9 is fixedly connected to the L-shaped rotating plate 8. The rotary motor 9 can drive the L-shaped rotating plate 8 to rotate.
[0035] The working principle of this utility model is as follows: First, the bearing 13 to be inspected is secured sequentially using fasteners. Specifically, the inner ring of the bearing 13 is fitted onto the positioning screw 16, and then the positioning nut 19 is screwed in, so that the bearing 13 is firmly clamped between the positioning nut 19 and the ring body 18. Subsequently, the camera 6 of the mobile visual inspection mechanism captures an image of the bearing 13 below and sends the captured image to the back-end control terminal for image recognition and analysis to determine whether there are defects or deformations in the outer ring contour of the bearing 13. It should be noted that visual inspection and analysis of surface defects is a well-known existing technology, and therefore will not be described in detail. During the testing process, the drive unit operates, causing each bearing 13 to rotate synchronously. Specifically, the drive motor 11 drives the corresponding pulley 15 to rotate, and the other pulleys 15 rotate synchronously under the transmission action of the transmission belt 25. The corresponding connecting rod 17 and positioning screw 16 rotate accordingly, thereby causing each bearing 13 to rotate synchronously. It should be noted that the calibration strip 12 can be used as a reference to determine whether there is deformation on the outer ring of the bearing 13. If the distance between a certain point on the outer ring of the bearing 13 and the calibration strip 12 is not the preset value, it indicates that there is a defect in the bearing 13 at that point.
[0036] After the bearing 13 is tested horizontally, it is then tested vertically. Specifically, the rotary motor 9 drives the L-shaped rotating plate 8 to rotate 90 degrees within the rotating groove 7, while the linear motor 5 moves slowly along the linear guide rail 4 to a preset position. At this point, the camera 6 reaches above the vertically erected bearing 13. Subsequently, the camera 6 continues to capture images of the outer ring of the bearing 13 below, while the drive unit continues to rotate each bearing 13 synchronously. During this process, the cylinder 20 of the calibration component extends its output shaft, causing the support rod 22 and the round head 23 to extend as well, finally bringing the rope 24 close to the bearing 13 as a reference. In this embodiment, the linear motor 5 is model YLB45, the rotary motor 9 is model 86GY, the drive motor 11 is model 42BYGH23, and the cylinder 20 is model MAL-B. This application, through the L-shaped rotating plate 8, fixing parts, driving parts and calibration parts, can effectively combine the flat-laying test, vertical test and rotation test of bearing 13, making the test process more comprehensive and thus improving the accuracy of the test results. In addition, this application can also test multiple bearings 13 at the same time, improving the test efficiency.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
