Abstract

This application discloses a probe holding mechanism for ultrasonic testing of bearing races in water immersion, relating to the field of clamping. It includes a frame, with a first motor fixedly mounted on the outer wall of the frame. A trapezoidal lead screw is provided at the output end of the first motor, a lead screw nut is provided on the outer side of the lead screw, and a movable seat is provided on the outer side of the lead screw nut. A first rotating shaft is rotatably connected inside the movable seat, and a first mounting plate is fixedly connected to the outer side of the first rotating shaft.

Description

Technical Field

[0001] This application relates to the field of clamping, and in particular to a probe clamping 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, water immersion ultrasonic testing of bearing rings is required using probes. However, the distance between the two probes in the existing technology cannot be adjusted, which prevents the probes from moving during testing and reduces the testing effect on the bearing rings. Utility Model Content

[0004] To address the problem in the prior art where the distance between the two probes cannot be adjusted, resulting in the probes being unable to move for testing and thus reducing the testing effect on bearing races, this application provides a probe holding mechanism for water immersion ultrasonic testing of bearing races.

[0005] The probe holding mechanism for water immersion ultrasonic testing of bearing rings provided in this application adopts the following technical solution:

[0006] A probe holding mechanism for ultrasonic testing of bearing rings by immersion includes a frame. A first motor is fixedly mounted on the outer wall of the frame. A trapezoidal lead screw is provided at the output end of the first motor. A lead screw nut is provided on the outer side of the trapezoidal lead screw. A movable seat is provided on the outer side of the lead screw nut. A first rotating shaft is rotatably connected inside the movable seat. A first mounting plate is fixedly connected to the outer side of the first rotating shaft. A first probe is fixedly mounted inside the first mounting plate. A second rotating shaft is rotatably connected inside the frame. A second mounting plate is fixedly connected to the outer wall of the second rotating shaft. A second probe is fixedly mounted inside the second mounting plate.

[0007] By adopting the above technical solution, the output end of the first motor of this application can drive the trapezoidal lead screw to rotate, and under the action of the lead screw nut, it can drive the moving seat to move. Since the first probe is set on the moving seat through the first mounting plate and the second probe is set on the frame through the second mounting plate, the first probe on the moving seat can move relative to the second probe on the frame, so that the height difference between the two probes can be adjusted, thereby improving the detection effect of the probe on the bearing ring.

[0008] Preferably, a coupling is provided between the output end of the first motor and the trapezoidal lead screw.

[0009] By adopting the above technical solution, the coupling can connect the output end of the first motor to the trapezoidal lead screw, so that the output end of the first motor can drive the trapezoidal lead screw to rotate.

[0010] Preferably, a mounting base is fixedly connected to the outer wall of the frame, and a ball bearing is fixedly installed inside the mounting base. The trapezoidal lead screw is rotatably connected to the ball bearing.

[0011] By adopting the above technical solution, when the trapezoidal lead screw receives power, it will rotate within the ball bearing, which improves the rotation efficiency of the lead screw. Furthermore, the ball bearing is fixedly installed inside the mounting base, which is fixedly connected to the frame, ensuring stable support for the trapezoidal lead screw.

[0012] Preferably, a first guide rail is fixedly connected to the outer wall of the frame, and the movable seat is slidably connected to the first guide rail.

[0013] By adopting the above technical solution, when the movable seat is subjected to external force, it will slide on the first guide rail. The first guide rail has a limiting and guiding function for the movable seat, so that the movable seat and the first probe on the outside can move stably.

[0014] Preferably, a bracket is fixedly connected to the outer wall of the movable seat near the frame; a second motor is fixedly installed on the outer wall of the bracket, a first synchronous pulley is fixedly connected to the output end of the second motor, a first synchronous belt is provided on the outer side of the first synchronous pulley, and a second synchronous pulley is provided on the other side of the first synchronous belt; the second synchronous pulley is fixedly connected to the first rotating shaft.

[0015] By adopting the above technical solution, the output end of the second motor can drive the first rotating shaft to rotate under the transmission of the first synchronous pulley, the first synchronous belt and the second synchronous pulley. Since the first mounting plate is fixedly connected to the outer side of the first rotating shaft and the first probe is fixedly installed on the inner side of the first mounting plate, the detection angle of the first probe can be adjusted to improve the detection effect of the probe on the bearing ring.

[0016] Preferably, a second guide rail is fixedly connected to the outer wall of the frame, and the second guide rail is slidably connected to the support.

[0017] By adopting the above technical solution, when the movable seat moves, it will drive the bracket to slide on the second guide rail. The second guide rail has a limiting and guiding function, which enables the bracket and the components on the bracket to move stably.

[0018] Preferably, a support plate is fixedly connected to the outer wall of the frame; a third motor is fixedly installed on the outer wall of the support plate, a third synchronous pulley is fixedly connected to the output end of the third motor, a second synchronous belt is provided on the outer side of the third synchronous pulley, and a fourth synchronous pulley is provided on the other side of the second synchronous belt; the fourth synchronous pulley is fixedly connected to the second rotating shaft.

[0019] By adopting the above technical solution, the output end of the third motor can drive the second rotating shaft to rotate under the transmission of the three synchronous pulleys, the second synchronous belt, and the fourth synchronous pulley. Since the second rotating shaft is fixedly connected to the second mounting plate, and the second probe is fixedly installed inside the second mounting plate, the detection angle of the second probe can be changed, thereby improving the detection effect of the probe on the bearing ring.

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

[0021] 1. When in use, the first motor can be started. The output end of the first motor drives the trapezoidal lead screw to rotate through the coupling. Under the action of the lead screw nut, the moving seat slides on the first guide rail, so that the moving seat can drive the first probe to move during the movement. This makes the height difference between the two probes adjustable and improves the detection effect of the probe on the bearing ring.

[0022] 2. During the testing process, this application can rotate the first mounting plate fixedly connected to the outer wall of the first rotating shaft, thereby changing the angle of the first probe set inside the first mounting plate. Additionally, it can rotate the second mounting plate fixedly connected to the outer wall of the second rotating shaft, thereby changing the angle of the second probe set inside the second mounting plate. This application allows for independent adjustment of the detection angles of the first and second probes, further improving the detection effect of the probes on the bearing rings.

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0029] This application discloses a probe holding mechanism for ultrasonic testing of bearing rings by water immersion.

[0030] Reference Figures 1-3 A probe holding mechanism for ultrasonic testing of bearing rings by water immersion includes a frame 1. A first motor 2 is fixedly installed on the outer wall of the frame 1, and the frame 1 can stably support the first motor 2. A trapezoidal lead screw 4 is provided at the output end of the first motor 2. The first motor 2 can provide power to the trapezoidal lead screw 4, so that the trapezoidal lead screw 4 rotates. A lead screw nut 7 is provided on the outer side of the trapezoidal lead screw 4, and a movable seat 8 is provided on the outer side of the lead screw nut 7. The trapezoidal lead screw 4 rotates and can drive the movable seat 8 to move under the action of the lead screw nut 7.

[0031] The movable base 8 is rotatably connected to a first rotating shaft 16, and a first mounting plate 17 is fixedly connected to the outside of the first rotating shaft 16. A first probe 18 is fixedly installed inside the first mounting plate 17. The first probe 18 can be set on the movable base 8 through the first rotating shaft 16 and the first mounting plate 17.

[0032] The frame 1 is rotatably connected to a second rotating shaft 24. The outer wall of the second rotating shaft 24 is fixedly connected to a second mounting plate 25. The second probe 26 is fixedly installed inside the second mounting plate 25. The second probe 26 can be mounted on the frame 1 through the second rotating shaft 24 and the second mounting plate 25.

[0033] Reference Figure 2 A coupling 3 is provided between the output end of the first motor 2 and the trapezoidal lead screw 4. The coupling 3 can connect the output end of the first motor 2 and the trapezoidal lead screw 4 together, so that the output end of the first motor 2 can drive the trapezoidal lead screw 4 to rotate.

[0034] Reference Figure 2A mounting base 5 is fixedly connected to the outer wall of the frame 1. A ball bearing 6 is fixedly installed inside the mounting base 5, and the trapezoidal lead screw 4 is rotatably connected to the ball bearing 6. When the trapezoidal lead screw 4 receives power, it will rotate within the ball bearing 6, which improves the rotation efficiency of the trapezoidal lead screw 4. Furthermore, the ball bearing 6 is fixedly installed inside the mounting base 5, which is fixedly connected to the frame 1, ensuring stable support for the trapezoidal lead screw 4.

[0035] Reference Figures 2-3 The outer wall of the frame 1 is fixedly connected to the first guide rail 9, and the movable seat 8 is slidably connected to the first guide rail 9. When the movable seat 8 is subjected to external force, it will slide on the first guide rail 9. The first guide rail 9 has a limiting and guiding function for the movable seat 8, so that the movable seat 8 and the first probe 18 on the outside can move stably.

[0036] Reference Figures 2-4 A bracket 10 is fixedly connected to the outer wall of the movable seat 8 near the frame 1. A second motor 12 is fixedly installed on the outer wall of the bracket 10. A first synchronous pulley 13 is fixedly connected to the output end of the second motor 12. A first synchronous belt 14 is provided on the outer side of the first synchronous pulley 13, and a second synchronous pulley 15 is provided on the other side of the first synchronous belt 14. The second synchronous pulley 15 is fixedly connected to the first rotating shaft 16. The output end of the second motor 12 can drive the first rotating shaft 16 to rotate under the transmission of the first synchronous pulley 13, the first synchronous belt 14, and the second synchronous pulley 15. Because a first mounting plate 17 is fixedly connected to the outer side of the first rotating shaft 16, and a first probe 18 is fixedly installed on the inner side of the first mounting plate 17, the detection angle of the first probe 18 can be adjusted to improve the detection effect of the probe on the bearing ring.

[0037] Reference Figures 2-3 The outer wall of the frame 1 is fixedly connected to a second guide rail 11, which is slidably connected to the bracket 10. When the movable seat 8 moves, it will drive the bracket 10 to slide on the second guide rail 11. The second guide rail 11 has a limiting and guiding function, so that the bracket 10 and the components on the bracket 10 can move stably.

[0038] Reference Figures 2-4A support plate 19 is fixedly connected to the outer wall of the frame 1. A third motor 20 is fixedly installed on the outer wall of the support plate 19. A third synchronous pulley 21 is fixedly connected to the output end of the third motor 20. A second synchronous belt 22 is provided on the outer side of the third synchronous pulley 21, and a fourth synchronous pulley 23 is provided on the other side of the second synchronous belt 22. The fourth synchronous pulley 23 is fixedly connected to the second rotating shaft 24. The output end of the third motor 20 can drive the second rotating shaft 24 to rotate under the transmission of the third synchronous pulley 21, the second synchronous belt 22, and the fourth synchronous pulley 23. Because the second rotating shaft 24 is fixedly connected to the second mounting plate 25, and a second probe 26 is fixedly installed inside the second mounting plate 25, the detection angle of the second probe 26 can be changed, thereby improving the detection effect of the probe on the bearing ring.

[0039] The working principle of the probe holding mechanism for water immersion ultrasonic testing of bearing rings is as follows:

[0040] When in use, the first motor 2 can be started. The output end of the first motor 2 drives the trapezoidal lead screw 4 to rotate through the coupling 3. Under the action of the lead screw nut 7, the moving seat 8 slides on the first guide rail 9. Since the first probe 18 is set on the moving seat 8 through the first rotating shaft 16 and the first mounting plate 17, and the second probe 26 is set on the frame 1 through the second rotating shaft 24 and the second mounting plate 25, the moving seat 8 can drive the first probe 18 to move during the movement, so that the height difference between the two probes can be adjusted, thereby improving the detection effect of the probe on the bearing ring.

[0041] Furthermore, during the detection process, the output of the second motor 12, under the action of the first synchronous pulley 13, the first synchronous belt 14, and the second synchronous pulley 15, drives the first rotating shaft 16 to rotate, which in turn drives the first mounting plate 17 fixedly connected to the outer wall of the first rotating shaft 16 to rotate, thereby changing the angle of the first probe 18 set inside the first mounting plate 17. Additionally, the output of the third motor 20, under the action of the third synchronous pulley 21, the second synchronous belt 22, and the fourth synchronous pulley 23, drives the second rotating shaft 24 to rotate, which in turn drives the second mounting plate 25 fixedly connected to the outer wall of the second rotating shaft 24 to rotate, thereby changing the angle of the second probe 26 set inside the second mounting plate 25. This application allows for the adjustment of the detection angles of the first probe 18 and the second probe 26 respectively, further improving the detection effect of the probes on the bearing rings.

[0042] 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.
