Description

Technical Field

[0001] This application relates to the field of clamping, and in particular to a self-centering clamping rotary roller mechanism for ultrasonic testing of bearing rings by water immersion. Background Technology

[0002] Bearing rings are one of the core components of rolling bearings, referring to the annular parts that make up the inner and outer rings of a rolling bearing. They are usually combined with rolling elements (such as steel balls, rollers, etc.) and cages to form a complete rolling bearing, used to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.

[0003] During the production process, bearing races need to undergo water immersion ultrasonic testing. However, existing technology cannot quickly limit the bearing races, nor can it rotate the bearing races during the testing process, resulting in the bearing races not being fully tested. Utility Model Content

[0004] To address the problem that the existing technology cannot quickly limit the bearing rings and cannot rotate the bearing rings during the testing process, resulting in the bearing rings not being fully inspected, this application provides a self-centering clamping rotating roller mechanism for water immersion ultrasonic testing of bearing rings.

[0005] The self-centering clamping rotary roller mechanism for water immersion ultrasonic testing of bearing rings provided in this application adopts the following technical solution:

[0006] A self-centering clamping rotary roller mechanism for ultrasonic testing of bearing rings by water immersion includes a frame. A support frame is fixedly connected to the top of the frame. A first motor is fixedly mounted on the outer wall of the support frame. A left-hand and right-hand lead screw is fixedly connected to the output end of the first motor. A lead screw nut is provided on both sides of the left-hand and right-hand lead screws. A movable seat is provided on the outer side of the lead screw nut. A movable frame is fixedly connected to the top of the movable seat. There are two movable frames. A first rotating shaft and a second rotating shaft are rotatably connected to the inner side of each movable frame. A first roller is fixedly connected to the outer wall of the first rotating shaft, and a second roller is fixedly connected to the outer wall of the second rotating shaft. A tray is fixedly connected to the bottom of the frame. A mounting base is fixedly connected to the top of the tray. A rotating roller is rotatably connected inside the mounting base. A bearing ring workpiece is placed on top of the rotating roller.

[0007] By adopting the above technical solution, the output end of the first motor in this application can drive the left and right lead screws to rotate. Under the action of the lead screw nut, it can drive the two moving frames to move towards each other. Because the inner side of each moving frame is rotatably connected to a first rotating shaft and a second rotating shaft, and the outer sides of the first rotating shaft and the second rotating shaft are respectively fixedly connected to a first roller and a second roller, the first roller and the second roller on both sides can limit the bearing ring workpiece. Then, the first roller and the second roller on both sides rotate, so that the bearing ring workpiece can rotate on the bottom rotating roller, and the rotating roller has a guiding effect on the bearing ring workpiece, which can improve the rotation effect of the bearing ring workpiece, so that the bearing ring workpiece can be fully inspected in water immersion ultrasonic testing.

[0008] Preferably, a support base is fixedly connected to the top of the support frame, and a ball bearing is fixedly installed inside the support base. The left and right helical screws are rotatably connected to the ball bearing.

[0009] By adopting the above technical solution, the left and right lead screws will rotate within the ball bearings under the action of external force, and the ball bearings can improve the rotation effect of the left and right lead screws. In addition, the support base can stably support the ball bearings and the left and right lead screws.

[0010] Preferably, the outer wall of the support frame is fixedly connected to a guide rail, and the movable seat is slidably connected to the guide rail.

[0011] By adopting the above technical solution, when the movable seat receives external force, it will slide on the guide rail. The guide rail has a limiting and guiding effect on the movable seat, enabling the movable seat to move stably.

[0012] Preferably, a drag chain is provided on the outer side of the movable seat.

[0013] By adopting the above technical solutions, the cable chain can provide traction and protection for the built-in cables, oil pipes, air pipes, water pipes, etc., allowing electronic components to operate stably.

[0014] Preferably, a mounting plate is fixedly connected to the outer side of the movable frame, and a second motor is fixedly installed inside the mounting plate. The output end of the second motor is fixedly connected to the first rotating shaft. A first synchronous pulley is fixedly connected to the outer wall of the first rotating shaft. A synchronous belt is provided on the outer side of the first synchronous pulley, and a second synchronous pulley is provided on one side of the synchronous belt. The second synchronous pulley is fixedly connected to the second rotating shaft.

[0015] By adopting the above technical solution, the output end of the second motor can drive the first rotating shaft to rotate. Since the first rotating shaft is fixedly connected to the outside of the first rotating shaft, it can drive the first roller to rotate. Under the transmission of the first synchronous pulley, the synchronous belt, and the second synchronous pulley, it can drive the second rotating shaft to rotate. Since the second rotating shaft is fixedly connected to the outside of the second rotating shaft, it can drive the second roller to rotate.

[0016] Preferably, a coupling is provided between the output end of the second motor and the first rotating shaft.

[0017] By adopting the above technical solution, the coupling can conveniently fix the first rotating shaft to the output end of the second motor.

[0018] Preferably, the bottom of the frame is fixedly connected to a plurality of base plates arranged in a rectangular pattern.

[0019] By adopting the above technical solution, multiple rectangular base plates can stably support the frame, enabling the components on the frame to operate stably.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. When in use, the output end of the first motor can drive the left and right lead screws to rotate. Under the action of the lead screw nut, the moving seat can be moved, which in turn can drive the moving frames on both sides to move towards each other and move towards the bearing ring workpiece. In addition, each side of the moving frame is provided with a first roller and a second roller, so the bearing ring workpiece can be limited by the first roller and the second roller on both sides.

[0022] 2. This application can drive the first roller and the second roller, which are fixedly connected to the first rotating shaft and the second rotating shaft respectively, to rotate, so that the bearing ring workpiece can rotate on the bottom rotating roller. The rotating roller has a guiding effect on the bearing ring workpiece, which can improve the rotation effect of the bearing ring workpiece and enable the bearing ring workpiece to be fully inspected in water immersion ultrasonic testing.

[0030] This application discloses a self-centering clamping rotating roller mechanism for water immersion ultrasonic testing of bearing rings.

[0031] Reference Figures 2-4 A self-centering clamping rotary roller mechanism for ultrasonic testing of bearing rings by water immersion includes a frame 1, a support frame 2 fixedly connected to the top of the frame 1, a first motor 3 fixedly installed on the outer wall of the support frame 2, the support frame 2 can stably support the first motor 3, a left and right rotary screw 4 fixedly connected to the output end of the first motor 3, the first motor 3 can provide stable power to the left and right rotary screw 4, screw nuts 7 are provided on both sides of the left and right rotary screw 4, and a movable seat 8 is provided on the outer side of the screw nuts 7. When the left and right rotary screw 4 rotates, it can drive the movable seat 8 to move under the action of the screw nuts 7. A movable frame 10 is fixedly connected to the top of the movable seat 8, and the movable seat 8 can drive the movable frame 10 to move during the movement.

[0032] There are two movable frames 10. The inner side of each movable frame 10 is rotatably connected to a first rotating shaft 15 and a second rotating shaft 19. The movable frames 10 on both sides can move towards each other. A first roller 20 is fixedly connected to the outer wall of the first rotating shaft 15, and a second roller 21 is fixedly connected to the outer wall of the second rotating shaft 19. The first roller 20 and the second roller 21 can rotate under the action of the first rotating shaft 15 and the second rotating shaft 19, respectively.

[0033] A tray 22 is fixedly connected to the bottom of the frame 1, and a mounting base 23 is fixedly connected to the top of the tray 22. The tray 22 can support the mounting base 23. A rotating roller 24 is rotatably connected inside the mounting base 23. A bearing ring workpiece 25 is placed on top of the rotating roller 24. When the first roller 20 and the second roller 21 on both sides of the bearing ring workpiece 25 rotate, they will drive the bearing ring workpiece 25 to rotate on the rotating roller 24. The rotating roller 24 has a guiding effect on the bearing ring workpiece 25, which can improve the rotation effect of the bearing ring workpiece 25.

[0034] Reference Figure 3 A support base 5 is fixedly connected to the top of the support frame 2. A ball bearing 6 is fixedly installed inside the support base 5, and the left and right helical screws 4 are rotatably connected to the ball bearings 6. Under the action of external force, the left and right helical screws 4 will rotate within the ball bearings 6, and the ball bearings 6 can improve the rotation effect of the left and right helical screws 4. In addition, the support base 5 can stably support the ball bearings 6 and the left and right helical screws 4.

[0035] Reference Figure 3 The outer wall of the support frame 2 is fixedly connected to a guide rail 9, and the movable seat 8 is slidably connected to the guide rail 9. When the movable seat 8 receives an external force, it will slide on the guide rail 9. The guide rail 9 has a limiting and guiding function for the movable seat 8, so that the movable seat 8 can move stably.

[0036] Reference Figure 3 A cable chain 11 is provided on the outside of the movable seat 8. The cable chain 11 can provide traction and protection for the built-in cables, oil pipes, air pipes, water pipes, etc., so that the electronic components can operate stably.

[0037] Reference Figures 4-5 A mounting plate 12 is fixedly connected to the outer side of the movable frame 10. A second motor 13 is fixedly installed inside the mounting plate 12. The output end of the second motor 13 is fixedly connected to the first rotating shaft 15. A first synchronous pulley 16 is fixedly connected to the outer wall of the first rotating shaft 15. A synchronous belt 17 is provided on the outer side of the first synchronous pulley 16. A second synchronous pulley 18 is provided on one side of the synchronous belt 17. The second synchronous pulley 18 is fixedly connected to the second rotating shaft 19. The output end of the second motor 13 can drive the first rotating shaft 15 to rotate. Because a first roller 20 is fixedly connected to the outer side of the first rotating shaft 15, it can drive the first roller 20 to rotate. Under the transmission of the first synchronous pulley 16, the synchronous belt 17, and the second synchronous pulley 18, it can drive the second rotating shaft 19 to rotate. And because a second roller 21 is fixedly connected to the outer side of the second rotating shaft 19, it can drive the second roller 21 to rotate.

[0038] Reference Figure 5A coupling 14 is provided between the output end of the second motor 13 and the first rotating shaft 15. The coupling 14 facilitates the fixed connection of the first rotating shaft 15 to the output end of the second motor 13.

[0039] Reference Figure 1 The bottom of the frame 1 is fixedly connected to multiple rectangular base plates 26.

[0040] By adopting the above technical solution, multiple rectangularly distributed base plates 26 can stably support the frame 1, enabling the components on the frame 1 to operate stably.

[0041] The working principle of this self-centering clamping rotating roller mechanism for water immersion ultrasonic testing of bearing rings is as follows:

[0042] In use, the output of the first motor 3 drives the left and right lead screws 4 to rotate. Under the action of the lead screw nut 7, the movable seat 8 can move. Because the movable seat 8 is fixedly connected to the movable frame 10, it can drive the two movable frames 10 to move towards each other and move towards the bearing ring workpiece 25. Furthermore, because each movable frame 10 is provided with a first roller 20 and a second roller 21 on its inner side, the bearing ring workpiece 25 can be limited by the first roller 20 and the second roller 21 on both sides.

[0043] Next, the output of the second motor 13 on the moving frame 10 can drive the first rotating shaft 15 to rotate through the coupling 14. Under the transmission of the first synchronous pulley 16, the synchronous belt 17, and the second synchronous pulley 18, the second rotating shaft 19 can be driven to rotate. In turn, the first roller 20 and the second roller 21, which are fixedly connected to the first rotating shaft 15 and the second rotating shaft 19, can be driven to rotate, so that the bearing ring workpiece 25 can rotate on the bottom rotating roller 24. The rotating roller 24 has a guiding effect on the bearing ring workpiece 25, which can improve the rotation effect of the bearing ring workpiece 25 and enable the bearing ring workpiece 25 to be fully inspected in water immersion ultrasonic testing.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
