The output end of the first hydraulic cylinder 12 is connected to the first opening and closing coil 13. The outer end of the first opening and closing coil 13 is movably engaged between the second opening and closing coil 15 and the triangular fixing plate.
[0025] By combining the opening and closing coil module 4 and the rotating magnetic field magnetized shell 5, the position of the opening and closing coil module 4 can be adjusted by moving the movable base 9 on the surface of the guide rail during use, thereby performing magnetic particle inspection on various positions on the surface of the axle 7, making the device easy to use for axles 7 of different lengths.
[0026] The movable support module 3 includes a movable support 16, a first handle 17, a first electrode clamping cylinder 18, and movable rollers 20. The movable support 16 is movably installed on one side surface of the top of the bed 1. The first handle 17 is movably installed on the outer end of the movable support 16. The first electrode clamping cylinder 18 is fixedly installed on the top of the movable support 16. Two axle support rollers 19 are movably installed on the end of the movable support 16 near the opening and closing coil module 4. A magnetized electrode is provided on the end of the first electrode clamping cylinder 18 near the axle support roller 19. Four movable rollers 20 are provided on the bottom end of the movable support 16.
[0027] The fixed support module 2 includes a geared motor 21, a fixed support 22, a transmission shaft 23, a second handle 24, and a second electrode clamping cylinder 25. The fixed support 22 is fixedly installed on the other side of the bed 1. The geared motor 21 is fixedly installed at the top of the fixed support 22. The output end of the geared motor 21 is connected to the transmission shaft 23 through a coupling. The end of the transmission shaft 23 is connected to a drive gear. Both sides of the top of the drive gear are meshed with driven gears. The outer ends of the driven gears are fixedly installed with axle support rollers 19. The top of the fixed support 22 is fixedly installed with a top plate. The top of the top plate is fixedly installed with the second electrode clamping cylinder 25. The end of the second electrode clamping cylinder 25 near the opening and closing coil module 4 is provided with a magnetizing electrode. The second handle 24 is movably installed at the outer end of the fixed support 22.
[0028] By cooperating with the fixed support module 2 and the movable support module 3, the position of the magnetized electrodes on both sides can be adjusted by the first electrode clamping cylinder 18 and the second electrode clamping cylinder 25 during use, thereby adjusting the size of the axle 7 that the device can clamp, making it convenient to clamp axles 7 of different sizes.
[0029] A control cabinet is provided on one side of the bed 1. A control console 8 is provided on the outer surface of the bed 1. The control console 8 is electrically connected to the control cabinet. Both ends of the axle 7 rest on the top surface of two axle support rollers 19. Wheels are provided on the outer surface of the axle 7. The wheels are inserted into the interior of the rotating magnetic field magnetization shell 5. Multiple nozzles are provided at the top of the rotating magnetic field magnetization shell 5.
[0030] In use, the magnetic particle inspection device for axles and gears first mounts both ends of the axle 7 onto the surfaces of the axle support rollers 19 on both sides, and then places the wheels or gears inside the magnetized housing 5 of the rotating magnetic field. The position of the opening and closing coil module 4 is then adjusted by moving the base 9 on the surface of the guide rail, thereby performing magnetic particle inspection on various locations on the surface of the axle 7. This allows the device to be used on axles 7 of different lengths.
[0031] When placing the axle 7, the positions of the magnetized electrodes on both sides can be adjusted by the first electrode clamping cylinder 18 and the second electrode clamping cylinder 25, respectively, so that the magnetized electrodes on both sides clamp the two ends of the axle 7, thereby adjusting the size of the axle 7 that the device can clamp, making the device convenient for clamping axles 7 of different sizes.
[0032] During magnetic particle testing, the opening and closing coil module 4 is moved forward on the surface of the movable base 9 by the forward and backward moving cylinder 11. After the opening and closing coil module 4 moves to the position of the axle 7, the first hydraulic cylinder 12 and the second hydraulic cylinder 14 drive the first opening and closing coil 13 and the second opening and closing coil 15 to rotate, so that the first opening and closing coil 13 and the second opening and closing coil 15 form a circle and clamp the axle 7 in the middle, which facilitates the magnetic particle testing operation. After the magnetic particle testing is completed, the first hydraulic cylinder 12 and the second hydraulic cylinder 14 drive the first opening and closing coil 13 and the second opening and closing coil 15 to rotate back, and then the opening and closing coil module 4 is driven backward by the traveling roller 10, so that the rotating magnetic field magnetized shell 5 is removed from the position of the wheel, so as not to obstruct the axle 7, thus facilitating the replacement of the axle 7.
[0033] By placing the wheel or gear of the axle 7 inside the rotating magnetic field magnetization housing 5, the rotating magnetic field magnetization module 6 can magnetize the wheel or gear, thus avoiding blind spots and omissions when the wheel or gear is large.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
