It can effectively solve the problems in the background art.

[0017] 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.

[0018] Please see Figure 1-4This utility model provides a technical solution: an automated surface flaw detection device for thrust cylindrical roller bearings, comprising a base 1, a feeding conveyor belt 2 for conveying bearings to be inspected, a flaw detection device mounting base 3, a first discharge conveyor belt 4 for conveying bearings with no surface flaws after inspection, and a second discharge conveyor belt 5 for conveying bearings with surface flaws after inspection. The feeding conveyor belt 2, the flaw detection device mounting base 3, the first discharge conveyor belt 4, and the second discharge conveyor belt 5 are evenly distributed counterclockwise around the center of the base 1 on the outer side of the base 1. The inner or outer ring of the thrust cylindrical roller bearing to be inspected is conveyed by the feeding conveyor belt 2. The material is placed below the top plate 12. A stepper motor is installed inside the base 1. The output shaft of the stepper motor passes through the upper surface of the base 1 and is connected to the rotating column 11. The top plate 12 is fixedly installed at the top of the rotating column 11. Several drive motors 13 are evenly arranged near the edge of the upper surface of the top plate 12. The output shaft of the drive motor 13 passes through the lower surface of the top plate 12 and is connected to the rotating shaft 14 through a coupling. A three-jaw chuck 15 for fixing the bearing is installed at the bottom of the rotating shaft 14. The inner or outer ring of the thrust cylindrical roller bearing is clamped by the three-jaw chuck 15. A flaw detection device for detecting flaws on the bearing surface is installed on the flaw detection device mounting base 3. The stepper motor drives the top plate 12, the three-jaw chuck 15, and the inner or outer ring of the thrust cylindrical roller bearing to rotate via the rotating column 11 to the flaw detection device mounting base 3 for inspection. Based on the inspection results, the bearing is moved to the first discharge conveyor belt 4 or the second discharge conveyor belt 5. The first discharge conveyor belt 4 transports the thrust cylindrical roller bearings confirmed to be free of surface damage to the assembly workshop for assembly. The second discharge conveyor belt 5 transports the thrust cylindrical roller bearings found to have surface damage to the manual re-inspection area for re-inspection or repair. This automated process is used to inspect the surface of the thrust cylindrical roller bearings. Flaw detection greatly improves work efficiency and reduces labor costs. Compared with manual flaw detection, the consistency and accuracy of the detection results are also improved. At the same time, since the top plate 12 is equipped with four sets of drive motors 13, rotating shafts 14 and three-jaw chucks 15, they can work simultaneously to pick up the inner or outer ring of the thrust cylindrical roller bearing from the feeding conveyor belt 2, perform surface flaw detection on the inner or outer ring of the thrust cylindrical roller bearing at the flaw detection device mounting seat 3, and place the inner or outer ring of the thrust cylindrical roller bearing after inspection onto the first discharge conveyor belt 4 or the second discharge conveyor belt 5, further improving work efficiency.

[0019] In a preferred embodiment, a fixed seat 21 is provided between the feeding conveyor belt 2 and the base 1. An electric push rod 23 is installed on the upper surface of the fixed seat 21. A lifting platform 22 is fixedly provided on the upper surface of the movable end of the electric push rod 23. The feeding conveyor belt 2 transports the inner or outer ring of the thrust cylindrical roller bearing to the lifting platform 22. The electric push rod 23 drives the inner or outer ring of the thrust cylindrical roller bearing on the lifting platform 22 to rise to the three-jaw chuck 15, so that the three-jaw chuck 15 can clamp and fix it.

[0020] In a further preferred embodiment, guide rods 24 are installed at the four corners of the upper surface of the fixed base 21, and guide rod holes matching the guide rods 24 are opened at the four corners of the upper surface of the lifting platform 22, which can greatly improve the stability of the lifting platform 22 during the lifting process.

[0021] Furthermore, a limiting block 25 with a diameter larger than the guide rod hole is fixedly provided at the top of the guide rod 24 to limit the height of the lifting platform 22; there is a certain distance between the top surface of the limiting block 25 and the bottom surface of the three-jaw chuck 15 to avoid affecting the rotation of the three-jaw chuck 15 after fixing the inner or outer ring of the bearing and following the top plate 12.

[0022] In a preferred embodiment, the upper surface of the flaw detection device mounting base 3 is provided with a sliding groove 31, and a sliding seat 32 is slidably disposed in the sliding groove 31. An ultrasonic probe 35 is installed on the top side surface of the sliding seat 32. The ultrasonic probe 35 is connected to an external ultrasonic flaw detector. The position of the ultrasonic probe 35 can be adjusted by moving the sliding seat 32, thereby performing flaw detection on the inner or outer ring surface of thrust cylindrical roller bearings of different diameters. This method is suitable for flaw detection on the outer surface of the inner and outer rings of thrust cylindrical roller bearings of different diameters.

[0023] Optionally, an electric telescopic rod can be installed on the sliding seat 32, and the ultrasonic probe 35 is installed on the side surface of the movable end of the electric telescopic rod, so as to perform flaw detection on the outer surface of the inner and outer rings of the thrust cylindrical roller bearings at different heights. At the same time, the ultrasonic probe 35 can be raised and lowered by telescopic movement to detect the inner surface of the inner and outer rings of the thrust cylindrical roller bearings, making the flaw detection more comprehensive.

[0024] In a preferred embodiment, a screw 33 is rotatably disposed within the slide groove 31. The screw 33 is threadedly connected to a screw hole on the lower part of the side surface of the sliding seat 32. The end of the screw 33 extends through the side surface of the flaw detection device mounting base 3 and is connected to the rotating handle 34. By rotating the handle 34, the screw 33 can be rotated, thereby conveniently adjusting the position of the sliding seat 32.

[0025] In a preferred embodiment, an air pump 16 corresponding to the three-jaw chuck 15 is installed on the upper surface of the top plate 12 near the drive motor 13. Both the air pump 16 and the drive motor 13 are electrically connected to the external controller in the form of slip rings. The stepper motor, feeding conveyor belt 2, electric push rod 23, ultrasonic flaw detector, first discharge conveyor belt 4 and second discharge conveyor belt 5 are all electrically connected to the external controller. The external controller can be a commonly used PLC controller or a microprocessor such as a single-chip microcomputer, such as a Mitsubishi FX2N series PLC controller. The air pump 16 is connected to the three-jaw chuck 15 through a conduit and is used to control the fixing and loosening of the inner or outer ring of the thrust cylindrical roller bearing by the three-jaw chuck 15, so as to facilitate the picking up or putting down of the inner or outer ring of the thrust cylindrical roller bearing.

[0026] The controller, air pump 16, stepper motor, drive motor 13, feeding conveyor belt 2, electric push rod 23, ultrasonic flaw detector, first discharge conveyor belt 4 and second discharge conveyor belt 5 used in this application are all commonly used electronic components in the prior art.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
