Description

Technical Field

[0001] This invention relates to the field of testing technology, and in particular to a device and method for testing the condition of the inner and outer rings of a bearing. Background Technology

[0002] A bearing is a mechanical component mainly used to support and guide rotating or linearly moving parts, reduce friction and improve efficiency. It achieves smooth movement by providing a sliding or rolling contact surface between the shaft and the supporting structure. In order to ensure the stability of the bearing during operation, it is necessary to inspect the inner and outer rings of the bearing.

[0003] Current bearing inner and outer ring condition testing devices can test both the inner and outer rings of the bearing, but they cannot test them simultaneously during the testing process. This makes the testing process complex and cumbersome, reducing the effectiveness of the device. Therefore, there is an urgent need to design a bearing inner and outer ring condition testing device. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a bearing inner and outer ring condition detection device and method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bearing inner and outer ring condition detection device includes a turntable and further includes:

[0007] The support component is located at the bottom of the turntable and is used to support the turntable, ensuring the stability of the turntable during operation.

[0008] There are four L-shaped frames, which are evenly and uniformly fixed in a ring on the top of the turntable.

[0009] The testing components consist of four parts, each mounted on one of four L-shaped brackets. These components are used to test the bearings placed on top of the turntable. Simultaneously, the inner and outer rings of the bearings can be cleaned and tested, ensuring the accuracy of the testing.

[0010] As a further technical solution of the present invention, the support component includes: a base, which is horizontally disposed below the turntable, and a U-shaped plate is fixedly installed on the top of the base. A rotating column is vertically rotatably installed on the top of the U-shaped plate, and the top of the rotating column is fixedly installed at the center of the bottom of the turntable. A drive motor is installed on the top of the base, and the output shaft of the drive motor is installed at the center of the end of the rotating column for driving the turntable to rotate.

[0011] As a further technical solution of the present invention, an annular groove is provided at the bottom of the turntable, and four sliding pillars are vertically fixed at the top of the base in a uniform annular distribution. The tops of the four sliding pillars are slidably installed inside the annular groove to limit the turntable and ensure the stability of the turntable when it rotates.

[0012] As a further technical solution of the present invention, the detection component includes: an upper disc, which is horizontally disposed below the horizontal edge of the L-shaped frame, and has external vertical rods vertically disposed at both ends of the bottom of the upper disc. The upper disc has a first inner cavity, and has a first horizontal groove communicating with the first inner cavity at both ends of the bottom of the upper disc. A first sliding plate is slidably disposed at both ends of the first inner cavity, and the top ends of the two external vertical rods pass through the first horizontal grooves and are rotatably mounted on the bottom of the two first sliding plates. Two symmetrically arranged electric telescopic rods are fixed on the surface of the upper disc, and the telescopic ends of the electric telescopic rods are fixedly mounted on the side of the first sliding plate for moving the first sliding plate and the external vertical rods through the electric telescopic rods.

[0013] As a further technical solution of the present invention, a lower disk is horizontally arranged below the upper disk, and two symmetrical inner vertical rods are vertically arranged at the bottom of the lower disk. A second inner cavity is opened inside the lower disk, and a second sliding plate is slidably arranged inside the second inner cavity. A second transverse groove communicating with the second inner cavity is opened at both ends of the bottom of the lower disk. The two inner vertical rods pass through the second transverse grooves and are rotatably installed at the bottom of the second sliding plate. A bidirectional lead screw is horizontally rotatably installed inside the second inner cavity, and the surface of the bidirectional lead screw is connected to the inside of the two second sliding plates by threads in opposite directions. A rotary motor is installed at one end inside the second inner cavity, and the output shaft of the rotary motor is installed at the center of the end face of the bidirectional lead screw, for driving the second sliding plate and the inner vertical rods to move through the bidirectional lead screw and the rotary motor.

[0014] As a further technical solution of the present invention, an outer clamping block is fixedly installed at the end of each of the two outer vertical rods, and an inner clamping block is fixedly installed at the end of each of the two inner vertical rods. A sponge is installed at the corresponding end of the inner and outer clamping blocks for cleaning the inner and outer rings of the bearing. An inner probe and an outer probe are fixedly installed at the bottom of the upper and lower discs, respectively, and the inner probe and the outer probe are used to detect the inner and outer rings of the bearing.

[0015] As a further technical solution of the present invention, a first gear is fixedly sleeved on the surface of each outer vertical rod, and a second gear is fixedly sleeved on the surface of each inner vertical rod. Two symmetrically arranged first racks are fixed at the bottom of the upper disk, and the protruding teeth on the first racks are connected by one-way elastic hinges. Two symmetrically arranged second racks are fixed at the bottom of the lower disk, and the protruding teeth on the second racks are connected by one-way elastic hinges. This is to ensure that the first gear and the second gear can only mesh with the first rack and the second rack in one direction, and the first gear and the first rack rotate 180 degrees in a single meshing with the second gear and the second rack.

[0016] As a further technical solution of the present invention, a first one-way bearing is installed on the top of the upper disk, and a second one-way bearing is installed on the top of the lower disk. A central shaft is fixedly installed on the inner ring of the first and second one-way bearings, and the central shaft passes through the upper disk.

[0036] Please see the appendix Figure 1 -Appendix Figure 8In a preferred embodiment, an outer clamping block 9 is fixedly installed at the end of each of the two outer vertical rods 11, and an inner clamping block 8 is fixedly installed at the end of each of the two inner vertical rods 10. Sponge wipes are installed at the corresponding ends of the inner clamping block 8 and the outer clamping block 9 for cleaning the inner and outer rings of the bearing. An inner probe 12 and an outer probe 13 are fixedly installed at the bottom of the upper disc 6 and the lower disc 7, respectively, and the inner probe 12 and the outer probe 13 are used to detect the inner and outer rings of the bearing, respectively.

[0037] Please see the appendix Figure 1 -Appendix Figure 8 In a preferred embodiment, a first gear 25 is fixedly sleeved on the surface of each outer vertical rod 11, and a second gear 27 is fixedly sleeved on the surface of each inner vertical rod 10. Two symmetrically arranged first racks 26 are fixedly fixed at the bottom of the upper disk 6, and the protruding teeth on the first racks 26 are connected by one-way elastic hinges. Two symmetrically arranged second racks 28 are fixedly fixed at the bottom of the lower disk 7, and the protruding teeth on the second racks 28 are connected by one-way elastic hinges. This allows the first gear 25 and the second gear 27 to mesh with the first racks 26 and the second racks 28 in only one direction, and the first gear 25 and the first rack 26 rotate 180 degrees in a single mesh with the second gear 27 and the second rack 28.

[0038] Please see the appendix Figure 1 -Appendix Figure 8 In a preferred embodiment, a first one-way bearing 22 is installed on the top of the upper disk 6, and a second one-way bearing 29 is installed on the top of the lower disk 7. A central shaft 21 is fixedly installed on the inner ring of the first one-way bearing 22 and the second one-way bearing 29, and the central shaft 21 passes through the upper disk 6. The first one-way bearing 22 and the second one-way bearing 29 are in opposite directions, so that only one of the upper disk 6 and the lower disk 7 rotates at a time.

[0039] Please see the appendix Figure 1 -Appendix Figure 8 In a preferred embodiment, a connecting plate 5 is horizontally arranged above the upper disc 6, and the top of the central shaft 21 is rotatably mounted on the bottom of the connecting plate 5. A U-shaped frame 19 is fixed on the top of the connecting plate 5. A forward and reverse motor 20 is installed on the bottom of the horizontal side of the U-shaped frame 19, and the output shaft of the forward and reverse motor 20 is installed at the center of the top of the central shaft 21. A hydraulic telescopic rod 4 is vertically installed on the top of the horizontal side of the L-shaped frame 3, and the telescopic end of the hydraulic telescopic rod 4 is fixedly installed on the bottom of the horizontal side of the U-shaped frame 19, which is used to drive the connecting plate 5 and its connecting parts to move up and down together.

[0040] When it is necessary to inspect the inner and outer rings of the bearing, first place the bearing on turntable 1;

[0041] Then, the hydraulic telescopic rod 4 drives the U-shaped frame 19 and the connecting plate 5 to move downward. The downward movement of the connecting plate 5 drives the central shaft 21, the first one-way bearing 22, the upper disc 6, the second one-way bearing 29 and the lower disc 7 to move upward. The downward movement of the upper disc 6 and the lower disc 7 drives the inner vertical rod 10, the inner clamping block 8, the outer vertical rod 11 and the outer clamping block 9 to move downward, so that the inner clamping block 8 can be placed inside the bearing and the outer clamping block 9 can be placed outside the bearing.

[0042] Then, the electric telescopic rod 23 drives the two first sliding plates 24 to move towards each other. The movement of the two first sliding plates 24 drives the two outer vertical rods 11 to move. The movement of the two outer vertical rods 11 drives the two outer clamping blocks 9 to move. The movement of the two outer clamping blocks 9 will clamp the bearing from the outer ring. It should be noted that since the protruding teeth on the first rack 26 are connected by a one-way elastic hinge, the movement of the first gear 25 does not mesh with the first rack 26. Therefore, the outer clamping blocks 9 will clamp the bearing. In addition, the rotary motor 32 drives the bidirectional lead screw 31 to rotate. The rotary motor 32 is a forward and reverse motor. The rotation of the bidirectional lead screw 31 drives the two second sliding plates 30 to move in opposite directions. The movement of the two second sliding plates 30 drives the two inner vertical rods 10 to move. The movement of the two vertical rods drives the two inner clamping blocks 8 to move in opposite directions. Thus, the sponge on the inner clamping block 8 can contact the inner ring of the bearing. It should be noted that since the protruding teeth on the second rack 28 are connected by a one-way elastic hinge, the movement of the second gear 27 does not mesh with the second rack 28. Therefore, the sponge on the inner clamping block 8 will clean the rotating inner ring of the bearing.

[0043] After the inner clamping block 8 and the outer clamping block 9 are adjusted, the forward and reverse motor 20 is started to rotate in the forward direction. The forward rotation of the forward and reverse motor 20 drives the central shaft 21 to rotate in the forward direction. The forward rotation of the central shaft 21 drives the upper disk 6 to rotate through the first one-way bearing 22. At this time, the central shaft 21 will not drive the lower disk 7 to rotate through the second one-way bearing 29. The rotation of the upper disk 6 drives the outer clamping block 9 and the clamped bearing to rotate. The inner probe 12 will then detect the inner ring of the bearing. At the same time, the sponge on the inner clamping block 8 will clean the inner ring of the bearing, ensuring the accuracy of the detection.

[0044] Next, the drive motor 15 drives the rotating column 18 to rotate, the rotating column 18 drives the rotating disk 1 to rotate, and the rotating disk 1 drives the components on it to rotate together, so that the four detection components can be switched in sequence. It should be noted that a controller is installed on the rotating disk 1, and all electrical equipment is electrically connected to the controller. The controller automatically controls the operation of the electrical equipment.

[0045] When the detection component is transferred to the next station, the controller controls the electric telescopic rod 23 to extend or retract once. When the electric telescopic rod 23 drives the outer vertical rod 11 to move away from the inner clamping block 8 via the first slide plate 24, the first gear 25 and the first rack 26 mesh, and the first gear 25 drives the outer vertical rod 11 and the outer clamping block 9 to rotate 180 degrees, so that the direction of the outer clamping block 9 driving the sponge is towards the outer ring of the bearing. When the electric telescopic rod 23 drives the outer vertical rod 11 to move closer to the inner clamping block 8 via the first slide plate 24, the first gear 25 and the first rack 26 do not mesh, and the sponge on the outer clamping block 9 will come into contact with the outside of the bearing. In addition, the rotary motor 32 drives the second slide plate 30 through the bidirectional lead screw 31. Each cycle of operation is performed once. Similarly, since the second gear 27 and the second rack 28 will cause the side of the inner clamping block 8 without sponge to face the inner ring of the bearing, the inner clamping block 8 will clamp the bearing from the inner ring. When the forward and reverse motor 20 drives the central shaft 21 to rotate in the opposite direction, the central shaft 21 rotates in the opposite direction and drives the lower disk 7 to rotate through the second one-way bearing 29. At this time, the central shaft 21 will not drive the upper disk 6 to rotate through the first one-way bearing 22. The rotation of the lower disk 7 drives the inner vertical rod 10 and the inner clamping block 8 to rotate. The rotation of the inner clamping block 8 will drive the clamped bearing to rotate. Then the outer probe 13 will detect the bearing from the outer ring of the bearing. During the detection, the sponge on the outer clamping block 9 will clean the outer ring of the bearing, ensuring the accuracy of the detection.

[0046] It should be noted that when the first gear 25 and the second gear 27 start to move following the outer vertical rod 11 and the inner vertical rod 10, they will not contact the first rack 26 and the second rack 28. In order to ensure that there is enough space for the outer clamping block 9 and the inner clamping block 8 to rotate when the outer vertical rod 11 and the inner vertical rod 10 rotate, so as to realize the replacement of the sponge;

[0047] In summary, by repeating the above steps, the inner and outer rings of the bearing can be inspected. During the inspection, the inner and outer rings of the bearing can be inspected automatically and continuously. The working state of the inner clamping block 8 and the outer clamping block 9 can be automatically switched during the inspection, from clamping blocks to sponge wipers, so that it has multiple functions, ensuring the quality of the bearing and the stability of its condition during use, thereby improving the effectiveness of the equipment.

[0048] 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.
