[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. To ensure the precision and quality of bearings, factories usually need to conduct appearance quality inspections on their internal parts (such as rollers, cages, inner rings, etc.) after the bearings are manufactured. The main contents of the inspection include identifying surface defects such as scratches, rust, cracks, and wear.

[0003] Currently, the identification of defects in the inner ring of bearings relies heavily on manual inspection using a manual inspection table with a magnifying glass or microscope. This method is not only time-consuming and labor-intensive, but also has low accuracy and poor stability. Utility Model Content

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] The bearing internal component appearance inspection table of this utility model embodiment is described below with reference to the accompanying drawings.

[0018] like Figures 1-5 As shown, the bearing internal component appearance inspection table of this utility model embodiment may include: support frame 1, conveying component 2, positioning mechanism 3 and inspection mechanism 4.

[0019] The conveying component 2 is mounted on the support frame 1.

[0020] Understandably, the conveyor assembly 2 is used to drive the bearing for automatic transport to achieve the functions of feeding and discharging materials.

[0021] The positioning mechanism 3 includes a fixed plate 301, a first positioning part 302, and a second positioning part 303.

[0022] The fixed plate 301 is located at the lower part of the conveying assembly 2, the first positioning part 302 is located at the lower part of the fixed plate 301, and the second positioning part 303 is located at the upper part of the fixed plate 301.

[0023] Understandably, the first positioning part 302 is used to keep the bearing transported in a straight line on the conveying assembly 2 to avoid deviation during the feeding process, and can be adjusted according to the diameter of bearings of different specifications; the second positioning part 303 is used to limit the bearing so that the bearing can remain stationary on the conveying assembly 2 during testing, and also isolates other bearings to be tested so that they remain stationary on the conveying assembly 2.

[0024] The testing mechanism 4 is located on the second positioning part 303.

[0025] Understandably, the inspection mechanism 4 can inspect the appearance of the inner ring of the bearing after the bearing is positioned by the second positioning part 303.

[0026] Specifically, when inspecting the inner ring of the produced bearing using the bearing internal component appearance inspection table, the relevant personnel first adjust the first positioning part 302 and the second positioning part 303 according to the diameter of the bearing, and then put the bearing into one end of the conveying component 2. The conveying component 2 is started to cooperate with the first positioning part 302 to position the bearing and control the bearing to run in a straight line.

[0027] The second positioning unit 303 is activated to position and fix the bearing, so that the first bearing remains stationary on the conveying assembly 2 after it runs to the lower part of the detection mechanism 4. At the same time, the detection mechanism 4 extends into the inner ring of the bearing, while the remaining bearings to be detected are limited and blocked by the second positioning unit 303 on the conveying assembly 2 and remain stationary.

[0028] The detection mechanism 4, in conjunction with the second positioning unit 303, drives the inner ring of the bearing to rotate. At this time, the detection mechanism 4 can photograph and identify scratches, pitting, cracks and wear on the surface of the bearing inner ring, and automatically determine the defects.

[0029] After the inspection is completed, the second positioning unit 303 is activated to lift and release the limit on the bearing, so that the next bearing to be inspected can move to the lower part of the inspection mechanism 4 for inspection. The inspected bearings are unloaded through the conveying component 2, and the relevant personnel sort out the unqualified bearings and continue to the next inspection process for qualified bearings.

[0030] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the first positioning part 302 includes a double-headed cylinder 3021, two connecting brackets 3022 and two baffles 3023.

[0031] The double-headed cylinder 3021 is installed on the lower part of the fixed plate 301, the two connecting frames 3022 are respectively connected to the two output ends of the double-headed cylinder 3021, and the two baffles 3023 are respectively connected to the corresponding connecting frames 3022 and located on the upper part of the conveying assembly 2.

[0032] Specifically, when positioning the bearing, the bearing is placed in the upper middle of the conveying assembly 2, and the double-headed cylinder 3021 is activated to drive the two connecting frames 3022 to move synchronously, so that the two baffles 3023 move closer or further apart. The spacing of the baffles 3023 is adjusted according to the diameter of the bearing, so that the bearing can always maintain a straight line when transported on the conveying assembly 2, and avoid the situation where the detection mechanism 4 is misaligned when the material is loaded due to deviation.

[0033] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the second positioning part 303 includes two first cylinders 3031, a mounting frame 3032, multiple limit rods 3033, multiple screws 3034, and multiple nuts 3035.

[0034] Two first cylinders 3031 are respectively installed at both ends of the upper part of the fixed plate 301, and the mounting frame 3032 is set between the upper ends of the two first cylinders 3031. Multiple through holes 3036 are opened on the front and rear sides of the mounting frame 3032, and multiple limit rods 3033 are respectively connected to the corresponding through holes 3036 through screws 3034 and nuts 3035.

[0035] It should be noted that the limiting rods 3033 described in this embodiment are all located between the two baffles 3023. There are two limiting rods 3033 installed on the front and rear sides of the mounting frame 3032, which can respectively position and fix the bearing being tested and the other bearings to be tested.

[0036] Specifically, after the spacing of the baffles 3023 is adjusted, the relevant personnel will install and fix the limiting rods 3033 onto the mounting frame 3032 by passing the screws 3034 through the corresponding through holes 3036 and with the nuts 3035, so that the spacing between two adjacent limiting rods 3033 is slightly smaller than the diameter of the bearing. The bearing is then placed from one end of the conveying assembly 2. As the conveying assembly 2 transports the bearing, it will be blocked when it moves to the limiting rods 3033. The control system built into the device will start the first cylinder 3031, which will push the mounting frame 3032 upward. The mounting frame 3032 will then drive the limiting rods 3033 upward, and all bearings will begin to be transported. When the first bearing is transported to the lower part of the detection mechanism 4, the first cylinder 3031 will retract, causing the mounting frame 3032 to descend. The mounting frame 3032 will then drive the lower limiting rods 3033 downward, simultaneously limiting and fixing the first bearing and the remaining bearings to be tested.

[0037] After the inspection mechanism 4 completes the appearance inspection of the inner ring of the first bearing, the first cylinder 3031 is started to drive the mounting frame 3032 and the limit rod 3033 to repeat the above operation steps, so that the next bearing is transported to the lower part of the inspection mechanism 4 for inspection. The inspected bearing is unloaded through the conveying assembly 2.

[0038] In one embodiment of this utility model, such as Figure 5 As shown, the detection mechanism 4 includes a support plate 401, a second cylinder 402, a slider 403, a motor 404, a rotating rod 405, a mounting rod 406, and a detection camera 407.

[0039] The support plate 401 is located in the middle of the mounting frame 3032. A through groove is opened inside the support plate 401. The second cylinder 402 is installed on the support plate 401. The slider 403 is connected to the output end of the second cylinder 402. The motor 404 is installed on the upper part of the slider 403. The rotating rod 405 is rotatably connected to the lower part of the slider 403 and passes through the through groove. The output end of the motor 404 is connected to the rotating rod 405. The mounting rod 406 is located at the lower part of the slider 403. The detection camera 407 is located at the lower end of the mounting rod 406.

[0040] It should be noted that the rotating rod 405 described in this embodiment is made of rubber and has anti-slip texture on its surface, which protects the inner ring of the bearing while increasing the friction with the inner ring of the bearing.

[0041] Specifically, when the bearing moves to the lower part of the rotating rod 405 and the detection camera 407, the limiting rod 3033 descends to position and fix the bearing. At the same time, the rotating rod 405 and the detection camera 407 also descend together into the inner ring of the bearing. The second cylinder 402 is activated to push the slider 403 to move. The slider 403 drives the rotating rod 405 and the mounting rod 406 to move. After the rotating rod 405 contacts the inner ring of the bearing, it stops. At this time, the motor 404 is started to drive the rotating rod 405 to rotate. The rotating rod 405 drives the inner ring of the bearing to rotate through friction. The detection camera 407 then performs a comprehensive inspection of the scratches, pitting, cracks and wear on the surface of the inner ring of the bearing, and automatically identifies and judges it as qualified or unqualified through the built-in control system.

[0042] In summary, the bearing inner component appearance inspection table of this utility model can automatically inspect the appearance quality of the bearing inner ring through the detection mechanism, positioning mechanism and conveying component, saving time and effort, improving the accuracy and efficiency of the inspection, and can be adjusted according to bearings of different specifications and sizes, with a wide range of applications.
