[0014] (III) Beneficial Effects
[0015] Compared with the prior art, this utility model provides a high-precision positioning and detection device for bearing manufacturing, which has the following advantages:
[0016] This high-precision positioning and inspection device for bearing manufacturing utilizes a clamping device, a rotating device, and a depth camera. The clamping device employs a pressure sensor to monitor the clamping force, ensuring workpiece stability during inspection and preventing product damage caused by over-clamping. The V-groove design allows for the correct centering and clamping of bearings of different specifications, enhancing the device's versatility.

[0023] 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.
[0024] Please see Figure 1-4A high-precision positioning and detection device for bearing manufacturing includes a worktable 1, a turntable 2, a clamping device, a discharge device, and a rotating device. The turntable 2 is mounted on the top of the worktable 1 via the rotating device. Four sets of support blocks 3 are mounted in a ring shape on the top of the turntable 2. The discharge device is mounted on the side wall of each set of support blocks 3. A fixing block 4 is mounted on the top wall of the support block 3. The clamping device is mounted on the side wall of the fixing block 4. The clamping device includes a rectangular groove 5, a bidirectional screw 6, a slider 7, a clamping plate 8, a V-groove 9, a pressure sensor 10, and a first motor 11. The rectangular groove 5 is formed on the side wall of the fixing block 4. The bidirectional screw 6 is rotatably mounted in the rectangular groove 5. The left and right ends of the bidirectional screw 6 are... The sliders 7 are threadedly installed on both sets of sliders 7. Clamping plates 8 are fixedly installed on the sidewalls of both sets of sliders 7. A V-groove 9 is formed between the two sets of clamping plates 8. A pressure sensor 10 is installed on the sidewall of the V-groove 9. One end of the bidirectional screw 6 passes through the rectangular groove 5 and is fitted with the first motor 11. A support frame 12 is installed on the top wall of the worktable 1. A depth camera 13 is installed on the bottom wall of the support frame 12. A waste material guide frame 14 is installed on one end sidewall of the worktable 1, and a good material guide frame 15 is installed on the front sidewall of the worktable 1. In this embodiment, during use, first ensure that the entire device is correctly installed and all electrical connections are normal. Then, electrically connect the depth camera 13 to the control system, and then... The bearing is placed on the turntable 2 at one end away from the waste guide frame 14, or it can be fed by an external feeding device. Material supply can be automatic or manual. The clamping device is activated, and the first motor 11 drives the bidirectional screw 6 to rotate. This rotates the two sets of sliders 7 within the rectangular groove 5, causing the two sets of clamping plates 8 to move inward until the V-groove 9 between the two sets of clamping plates 8 just contacts and gently secures the bearing. The special design of the V-groove 9 allows the bearing to be centered and clamped within the clamping plates 8. At this point, the pressure sensor 10 monitors the applied pressure to ensure sufficient clamping force without damaging the workpiece. Then, the turntable 2 is rotated via a rotating device, rotating the clamped bearing from one end of the worktable 1 to directly below the support frame 12, aligning it with the shaft being tested. The system takes pictures to obtain the three-dimensional dimensional information of the bearing. By analyzing the data collected by the depth camera 13, the system can accurately measure various parameters of the bearing, such as inner and outer diameters and width, and compare them with preset standard values to determine whether they are qualified. When the bearing under the support frame 12 is being tested, the clamping device at the end away from the scrap guide frame 14 can clamp the second group of bearings to be tested, thereby realizing the connection test. When the test result is unqualified, the turntable 2 continues to rotate, and the second group of clamped bearings moves to the bottom of the depth camera 13. At the same time, the clamping device releases the first group of unqualified bearings, and the unqualified bearings are pushed into the scrap guide frame 14 by the discharge device below the corresponding clamping device. An external scrap frame is placed below the scrap guide frame 14.Non-conforming waste materials are collected. When the first set of bearings is qualified, the turntable 2 continues to rotate via a rotating device, aligning the qualified bearings with the good material guide frame 15. The qualified material is then pushed out through the corresponding discharge device and enters the external collection frame below the good material guide frame 15. This device uses a pressure sensor 10 to monitor the clamping force, avoiding product damage due to over-clamping and ensuring workpiece stability during inspection. A depth camera 13 is used for non-contact measurement. Combined with a precise mechanical structure design, high-precision inspection of bearing dimensions is achieved. It supports the inspection of bearings of different specifications; simply adjusting the position of the clamping device and setting the corresponding inspection parameters can adapt to various product requirements.
[0025] Preferably, in this embodiment, the discharge device includes an electric telescopic rod 16, a groove 17, and a push plate 18. The electric telescopic rod 16 is installed at the end of each set of support blocks 3 away from the clamping plate 8. The groove 17 is provided at the end of each set of support blocks 3 near the clamping plate 8. The push plate 18 is slidably installed within the groove 17. The output end of the electric telescopic rod 16 passes through the side wall of the support block 3 and connects to the push plate 18. After the bearing is fixed by the clamping device and its dimensions and other parameters are detected by the depth camera 13, the system will determine whether the bearing is qualified according to a preset standard. If the detection result shows that the bearing is unqualified, the control system will instruct the corresponding electric telescopic rod... When activated, the electric telescopic rod 16 extends, pushing the push plate 18 connected to it forward along the groove 17. Under the action of the electric telescopic rod 16, the push plate 18 slides from one end of the support block 3 to the other, directly contacting and pushing the bearing located on the support block 3. As the electric telescopic rod 16 continues to extend, the push plate 18 pushes the unqualified bearing out of the support block 3, causing it to fall into the pre-set waste guide frame 14 and into the external waste box for collection. For qualified products, the corresponding electric telescopic rod 16 is triggered, guiding them through the good material guide frame 15 and collecting them through the external collection box. This realizes the automatic sorting function after inspection, reduces the need for manual intervention, and improves production efficiency.
[0026] Preferably, in this embodiment, the rotating device includes a rotating shaft 19, a driven gear 20, a second motor 21, and a driving gear 22. The rotating shaft 19 is rotatably mounted on the bottom wall of the turntable 2, and the driven gear 20 is sleeved on the outer wall of the rotating shaft 19. The second motor 21 is mounted on the bottom wall of the worktable 1, and the driving gear 22 is mounted through the worktable 1 at the output end of the second motor 21. The driving gear 22 and the driven gear 20 are meshed together. When the position of the turntable 2 needs to be adjusted, the control system issues a command to start the second motor 21. The second motor 21 starts to run, driving the driving gear 22 mounted on its output end. Rotation occurs because the driving gear 22 meshes with the driven gear 20. The rotation of the driving gear 22 directly causes the driven gear 20 to rotate synchronously. The driven gear 20 is fixed on the rotating shaft 19, so it drives the rotating shaft 19 to rotate together. As the rotating shaft 19 rotates, the turntable 2 mounted on the top of the rotating shaft 19 also rotates until it reaches the required position or angle. During this process, the position of the turntable 2 can be precisely adjusted by controlling the speed and rotation direction of the second motor 21. Once the turntable 2 reaches the predetermined position, the control system commands the second motor 21 to stop running. At this time, the turntable 2 is accurately positioned and can proceed to the next step, such as inspection, loading and unloading materials.
[0027] Preferably, in this embodiment, a guide ring 23 is fixedly installed on the bottom wall of the turntable 2, and a guide groove 24 is provided on the top wall of the worktable 1. The guide ring 23 and the guide groove 24 are slidably connected. The sliding connection between the guide ring 23 and the guide groove 24 provides an additional support point for the turntable 2, which helps to maintain the levelness and stability of the turntable 2 during rotation. This can effectively reduce measurement errors caused by the shaking or offset of the turntable 2. By precisely sliding the guide ring 23 along the guide groove 24, it can be ensured that the turntable 2 can accurately return to the predetermined position after each rotation, which improves the repeatability of the entire system. This is especially important for applications that require high-precision detection of multiple identical positions.
[0028] Preferably, in this embodiment, both the first motor 11 and the second motor 21 are servo motors. Servo motors can provide very precise position control, which is crucial for ensuring that the clamping force is appropriate, avoiding damage to the workpiece, and ensuring that the turntable 2 rotates accurately to the required position.
[0029] Preferably, in this embodiment, support legs 25 are installed at the four corners of the bottom of the workbench 1. The support legs 25 at the four corners provide a stable foundation for the workbench 1, which helps to prevent the workbench 1 from shaking or tilting during operation.
[0030] Preferably, in this embodiment, the support frame 12 is an L-shaped design. The L-shaped design allows the support frame 12 to be installed close to the edge of the workbench 1 or other structures, minimizing the floor space occupied and providing more operating space for the operator.

The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
