This phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content

This facilitates the intermittent revolution of several vacuum pumps while they rotate on their own axis, thereby enabling gradual detection of defects on the outer wall of the vacuum pumps. This effectively improves the convenience of detection and solves the problem of detection stagnation caused by fixed vacuum pumps, which affects detection efficiency.

[0006] Preferably, the first driving gear is incompletely gear-shaped and meshes with the planetary gear, which facilitates the intermittent rotation of the planetary gear by the first driving gear.

Specifically, the movable shafts are distributed at equal angles along the axial center line of the movable disk, and the fixture is located at one end of the top of the movable shaft after passing through the outer wall of the movable disk, which facilitates the movable disk to drive the fixture to rotate around the workbench through the movable shaft, and then enables the detection probe on one side of the workbench to perform surface shooting on the vacuum pump after approaching, and transmits the拍摄的数据传输至检测器进行数据对比后,实现检测工作。

[0010] Preferably, the driven gears are distributed at equal angles along the axial center line of the movable disk, and the driven gears are meshed with the second driving gear, which facilitates the rotation of the driven gears.

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-4, the utility model provides a technical solution: an automobile vacuum pump quality inspection device, which includes two support frames 1. One end of the two support frames 1 close to each other is fixedly connected with a workbench 2. A detector 3 is arranged on the top of the workbench 2. A detection probe 4 matched with the detector 3 is fixedly connected to one side of the workbench 2. A support column 5 is fixedly connected to the bottom of the workbench 2. A driving motor 6 is fixedly connected to the inner wall of the support column 5. The output shaft of the driving motor 6 is fixedly connected with a driving shaft 7 through a coupling. The outer wall of the driving shaft 7 is fixedly connected with a first driving gear 8 and a second driving gear 9 from top to bottom. The outer wall of the support column 5 is movably connected with a movable disc 10 through a bearing. A planet carrier 11 is fixedly connected to the outer wall of the support column 5. A support shaft 12 is movably connected to the bottom of the planet carrier 11. A planet gear 13 is fixedly connected to the bottom of the support shaft 12. The inner wall of the movable disc 10 is movably connected with a movable shaft 14. A driven gear 15 is fixedly connected to the bottom of the movable shaft 14. A clamp 16 is fixedly connected to the top of the movable shaft 14, which facilitates driving several vacuum pumps to rotate intermittently while rotating, so as to gradually detect the outer wall defects of the vacuum pumps, effectively improving the convenience of detection, and solving the problem that the detection stagnates due to fixing the vacuum pump, thus affecting the detection efficiency.

[0021] Preferably, the first driving gear 8 is in the shape of an incomplete gear, and the first driving gear 8 is matched with the planet gear 13, which facilitates the first driving gear 8 to intermittently drive the planet gear 13 to rotate. Specifically, the planet gears 13 are equally angularly distributed along the axial center line of the first driving gear 8, thereby improving the stability when the planet gear 13 rotates to drive the movable disc 10 to rotate.

[0022] Preferably, tooth blocks are equally angularly arranged on the inner wall of the movable disc 10, and the movable disc 10 is connected with the planet gear 13 through the tooth blocks, which facilitates the planet gear 13 to rotate to drive the movable disc 10 to rotate. Specifically, the inner wall of the movable disc 10 is a hollow structure, and the outer wall of the movable disc 10 is distributed in a "convex" shape, which facilitates the first driving gear 8 to drive the planet gear 13 to rotate effectively inside the movable disc 10.

[0023] Preferably, the planet carrier 11 is distributed in a "cross" shape, and the planet gear 13 is rotatably connected with the planet carrier 11 through the support shaft 12, which facilitates the support of the support shaft 12. Specifically, the number of the support shafts 12 is the same as the number of the planet gears 13, thus ensuring the effective support of the support shafts 12 for the planet gears 13.

[0024] Preferably, the movable shaft 14 passes through the outer wall of the movable disk 10 via a bearing, and the movable shaft 14 is rotatably connected via the bearing. This facilitates the support of the movable shaft 14 by the movable disk 10, so that the movable disk 10 drives the movable shaft 14 to revolve after rotation. Specifically, the movable shaft 14 is distributed at equal angles along the axial center line of the movable disk 10, and the clamp 16 is located at the top end of the movable shaft 14 after it passes through the outer wall of the movable disk 10. This facilitates the movable disk 10 to drive the clamp 16 to rotate around the worktable 2 via the movable shaft 14, thereby allowing the detection probe 4 on one side of the worktable 2 to perform surface imaging of the vacuum pump that is close behind, and transmit the image data to the detector 3 for data comparison to achieve the detection work.

[0025] Preferably, the driven gears 15 are distributed at equal angles along the axial centerline of the movable disk 10, and the driven gears 15 mesh with the second driving gear 9, which facilitates the rotation of the driven gears 15. Specifically, the driven gears 15 are located at the bottom of the movable disk 10, which facilitates the rotation of the driven gears 15 and the driving gear 16 through the movable shaft 14 to revolve. This allows the detection probe 4 to take multi-angle pictures of the vacuum pump positioned on the clamp 16, improving the accuracy of surface inspection of the vacuum pump and solving the problem of insufficient inspection.

[0026] In use, first, the vacuum pump is fixed inside the fixture 16. Then, the drive motor 6 is started, causing the drive shaft 7 to rotate. The drive shaft 7 then rotates the first drive gear 8. Since the first drive gear 8 is an incomplete gear, the teeth on the outer wall of the first drive gear 8 will rotate when they approach the planetary gear 13, and stop rotating when they move away from the planetary gear 13. This intermittently drives the planetary gear 13 to rotate. When the planetary gear 13 rotates, it will drive the movable disk 10 to rotate. This causes the movable disk 10 to drive the fixture 16 to revolve via the movable shaft 14. This allows the fixture 16 to move the vacuum pump at different angles to gradually move in front of the detection probe 4. The information captured by the detection probe 4 is transmitted to the detector 3 for comparison and surface defect detection. During this process, since the movable disk 10 rotates intermittently, when the movable disk 10 stops rotating, another vacuum pump can be installed in another spare fixture 16 to perform continuous detection. When the drive shaft 7 rotates, it will simultaneously drive the second drive gear 9 to rotate, which in turn drives the driven gear 15 to rotate. The driven gear 15 drives the fixture 16 to rotate through the movable shaft 14. Thus, when the vacuum pump moves in front of the detection probe 4, it will rotate, allowing for a more comprehensive inspection of the surface of the vacuum pump and improving the accuracy of the inspection.
