[0025] Furthermore, the terms used below are defined based on the functions of this utility model and may vary depending on the user's or operator's intent or convention. Therefore, these terms are defined based on the entire contents of this specification.

[0026] like Figures 1 to 6 As shown, a bearing outer ring leak detection device includes a vibratory feeder 1 and bearing outer rings 2. Multiple bearing outer rings 2 are arranged inside the vibratory feeder 1 and conveyed out by the vibratory feeder 1. Each bearing outer ring 2 has an inner hole 201. A mounting plate 3 is fixedly mounted on the outer wall of the vibratory feeder 1. A feed guide plate 4 is mounted on the mounting plate 3. The inlet of the feed guide plate 4 is connected to the outlet of the vibratory feeder 1 for conveying the bearing outer rings 2. Two connecting strips 6 are provided on the feed guide plate 4. A limiting strip 5 is provided at the bottom of the 6 to limit and protect the bearing outer ring 2 conveyed on the feed guide plate 4, preventing the bearing outer ring 2 from deviating. A worktable 7 is provided on the front of the mounting plate 3. Multiple support columns 8 are provided at the bottom of the worktable 7 to support the worktable 7 on the ground. A first limiting plate 10 and a second limiting plate 11 are provided on the worktable 7. The first limiting plate 10 and the second limiting plate 11 are arranged in parallel. The channel formed by the first limiting plate 10 and the second limiting plate 11 is directly opposite the discharge channel of the feed guide plate 4, which facilitates the conveying of the bearing outer ring 2.

[0027] like Figure 2As shown, a connecting sheet metal 12 is provided on the second limiting plate 11, and a first sensor 13 is threadedly connected to the side wall of the connecting sheet metal 12. A third limiting plate 14 is provided on the worktable 7, and a slide is formed between the side wall of the third limiting plate 14 and the second limiting plate 11. A push plate 16 is slidably arranged in the slide. A first cylinder 15 is provided on the side wall of the push plate 16. The first cylinder 15 pushes the push plate 16 to push the outer ring 2 of the bearing. The first sensor 13 controls the first cylinder 15 to push the push plate 16.

[0028] like Figure 2 As shown, a fixing plate 17 is provided on the workbench 7, which limits the bearing outer ring 2. A fixing sheet metal 18 is provided on the top of the fixing plate 17, and a second sensor 19 is provided on the fixing sheet metal 18. The second sensor 19 is used to detect whether the bearing outer ring 2 is in position. When the bearing outer ring 2 reaches below the second sensor 19, the first cylinder 15 is activated to push the push plate 16 to push the bearing outer ring 2 forward. A detection and adjustment mechanism 9 and a pressure block 20 are provided opposite each other on the workbench 7. A magnet 26 is embedded on the top of the workbench 7. The magnet 26 is located between the detection and adjustment mechanism 9 and the pressure block 20. The bearing outer ring 2 is temporarily held by the magnet 26. A contact strip 21 is engaged at the bottom of the pressure block 20. The contact part of the contact strip 21 with the bearing outer ring 2 is arc-shaped. A displacement sensor is embedded in the arc-shaped part of the contact strip 21. The detection and adjustment mechanism 9 and the displacement sensor are used to measure the inner wall thickness of the bearing outer ring 2 in order to detect whether there is any omission in the machining of the inner hole 201 of the bearing outer ring 2.

[0029] like Figure 5 As shown, the detection and adjustment mechanism 9 includes a fixed block 91, which is mounted on the workbench 7. A third cylinder 92 is mounted on the top of the fixed block 91, and a fourth cylinder 93 is fixedly mounted on the output end of the third cylinder 92. A movable block 94 is fixedly connected to the output end of the fourth cylinder 93. A receiving groove is provided on the top of the workbench 7. The movable block 94 has an L-shaped structure, and its bottom is located in the receiving groove. A detection head 941 is mounted on the end of the movable block 94. The detection head 941 is arc-shaped. The third cylinder 92 and the fourth cylinder 93 work together to drive the movable block 94 to move up, down, left, and right in the receiving groove, so that the detection head 941 abuts against the inner wall of the inner hole 201 of the outer ring 2 of the bearing. The detection head 941 is directly opposite the arc-shaped part of the contact strip 21, which facilitates the detection of the wall thickness of the inner hole 201 of the outer ring 2 of the bearing.

[0030] like Figure 1 and Figure 4As shown, a support block 23 is embedded in the top of the workbench 7. The top of the support block 23 is flush with the top of the workbench 7. Sliding grooves 231 are formed at both ends of the support block 23. Two baffles 24 are slidably disposed on the top of the support block 23. Sliding strips 25 are provided at both ends of the bottom of the two baffles 24, and the two sliding strips 25 are respectively slidably disposed within the two sliding grooves 231. A second cylinder 22 is disposed on the workbench 7. The output end of the second cylinder 22 is fixedly connected to the side wall of the baffle 24. The top of the workbench 7... The workbench 7 has a discharge port 71, which is directly opposite the baffle 24. The workbench 7 has a discharge bin 27 on its side wall, which is directly opposite the outlet channel of the bearing outer ring 2. The workbench 7 has a controller 28 on its other side wall, and a column 29 is provided at the bottom of the controller 28. The controller 28 has multiple indicator lights 30 on its front. The detection and adjustment mechanism 9, the first sensor 13, the first cylinder 15, the second sensor 19, and the second cylinder 22 are all connected to the controller 28.

[0031] Specifically, the bearing outer ring 2 is conveyed to the feed guide plate 4 via the vibratory feeder 1, and then transported to the worktable 7 via the feed guide plate 4. The bearing outer ring 2 advances along the channel formed by the first limiting plate 10 and the second limiting plate 11 until it slides below the second sensor 19. When the second sensor 19 detects that the bearing outer ring 2 has reached the position, it transmits a signal to the controller 28. The controller 28 controls the first cylinder 15 to start pushing the push plate 16 to slide, pushing the bearing outer ring 2 between the detection and adjustment mechanism 9 and the pressure block 20. At the same time, the magnet 26 attracts the bearing outer ring 2 temporarily. The first cylinder 15 drives the push plate 16 to reset. The first sensor 13 controls the stroke of the push plate 16. The controller 28 controls the operation of the detection and adjustment mechanism 9. The fourth cylinder 93 lifts the movable block 94 to a suitable height. The third cylinder 92 pushes the fourth cylinder 93 and the movable block 94 forward, so that the detection head 941 presses against the inner hole 201 of the bearing outer ring 2. On the inner wall, a displacement sensor embedded in the arc-shaped part of the contact strip 21 detects the thickness of the inner wall of the inner hole 201 of the bearing outer ring 2. The displacement sensor transmits the detected data to the controller 28 for analysis and comparison with the set thickness parameters. If the thickness is qualified, it passes between the support block 23 and the baffle 24 and finally falls into the qualified product collection box through the discharge bin 27. If the thickness is unqualified, it means that the inner hole 201 of the bearing outer ring 2 has been missed. When the unqualified bearing outer ring 2 enters between the support block 23 and the baffle 24, the controller 28 controls the second cylinder 22 to start. The second cylinder 22 pushes the baffle 24 to slide along the slide groove 231 of the support block 23, thereby sliding the unqualified bearing outer ring 2 to the discharge port 71 and falling into the unqualified product collection box. Then it is collected and reprocessed. The above process is repeated to detect and classify the bearing outer rings 2 transported by the vibratory plate 1, completing the entire missing processing detection process. The detection is accurate and efficient.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
