Description

A magnetizing device for an induction sleeve Technical Field

[0001] The present invention relates to the technical field of shaft sleeve magnetization, in particular to a magnetization device for an induction shaft sleeve. Background Art

[0002] Magnetic materials are divided into many tiny regions, each called a magnetic domain. Each domain has its own magnetic moment (i.e., a tiny magnetic field). Normally, the directions of the magnetic moments of each domain differ, canceling out the magnetic fields, resulting in the overall material appearing non-magnetic. When the directions of the domains align, the entire material becomes magnetized. Magnetization involves aligning the directions of the magnetic moments of the domains within a material. When a non-magnetic material is placed in a strong magnetic field, it becomes magnetized. However, not all materials can be magnetized; only a few metals and metal compounds can be magnetized.

[0003] At present, when magnetizing a sleeve, the sleeve to be magnetized is generally clamped and fixed by a claw plate on a machine tool, and then the claw plate is driven to drive the sleeve to rotate. Then, a worker holds a U-shaped magnet close to the sleeve to magnetize the sleeve. However, during this magnetization process, the worker magnetizes the sleeve by holding the U-shaped magnet. Due to the shaking of the human hand, the distance between the U-shaped magnet and the sleeve is unstable, resulting in an unsatisfactory magnetization effect. At the same time, the degree of magnetization of the sleeve cannot be judged and can only be judged based on the worker's experience, which is prone to large errors.

[0004] To this end, we propose a magnetizing device for an induction sleeve to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] As shown in Figures 1 to 5, a magnetization device for an induction sleeve includes a working box 1, an adjustment component, a clamping component and a measuring component, wherein the adjustment component, the clamping component and the measuring component are all arranged on the working box 1. When in use, the clamping component is first used to clamp and fix the position of the sleeve 26, and then the adjustment component is used to adjust the energized coil 5 inside it close to the sleeve 26 to a specified position, and then the sleeve 26 is driven to rotate a corresponding number of circles so that the sleeve 26 is magnetized by the energized coil 5; during this process, the measuring component can measure the magnetic induction intensity of the sleeve 26 so that the sleeve 26 can reach the preset magnetic induction intensity.

[0033] Regarding the setting of the above-mentioned adjustment component, the adjustment component includes a moving rod 2 and a driving member. The moving rod 2 is horizontally slidably installed inside the working box 1, and a horizontal plate 3 is fixedly provided at the bottom of the moving rod 2. Two clamping plates 4 are hingedly installed at the bottom of the horizontal plate 3. A clamping area with adjustable size is formed between the two clamping plates 4, and an energized coil 5 is provided on the clamping area; the driving member is arranged inside the working box 1, and the driving member is used to drive the moving rod 2 to slide horizontally.

[0034] After the sleeve 26 is fixed, the magnitude of the current can be controlled to control the magnetic field strength of the energized coil 5, so that the energized coil 5 can reach a preset magnetic field strength. The energized coil 5 can then be moved closer to the sleeve 26 using a driving member until the energized coil 5 reaches a specified position. The sleeve 26 can then be driven to rotate so that the energized coil 5 magnetizes the sleeve 26 circumferentially.

[0035] As shown in Figure 2, for the setting of the clamping area, the two clamping plates 4 can be arranged in an inverted eight shape, and limiting plates 14 are fixedly set at both ends of the horizontal plate 3. The two limiting plates 14 are respectively set corresponding to the two clamping plates 4, and the two limiting plates 14 are respectively provided with reset springs 15 fixedly connected to the corresponding clamping plates 4. The two reset springs 15 are always in a compressed state, and thus the two clamping plates 4 always have a tendency to move closer to each other, so that the energized coil 5 can be clamped and fixed.

[0036] Furthermore, the driving member mentioned above can be provided with a servo motor 7 and a special-shaped rod 8, a mounting bracket 9 is fixedly provided on the top inner wall of the working box 1, the servo motor 7 is fixedly provided on the mounting bracket 9, and the output shaft of the servo motor 7 is fixedly provided with a turntable 10, the middle position of the special-shaped rod 8 is hingedly installed inside the working box 1, a connecting rod 11 is hingedly installed on the turntable 10, and the connecting rod 11 is hingedly connected to one end of the special-shaped rod 8, and the other end of the special-shaped rod 8 is hingedly installed with a follower rod 12, and the follower rod 12 is hingedly connected to the moving rod 2. By driving the servo motor 7 to work, the turntable 10 can be rotated to a corresponding angle, which can then drive the connecting rod 11 and the special-shaped rod 8 to rotate accordingly, that is, the follower rod 12 can drive the moving rod 2 to move, and the movement of the moving rod 2 can drive the energized coil 5 to move; by providing the servo motor 7 and the turntable 10, etc., the moving rod 2 can drive the energized coil 5 to move accurately, which facilitates the magnetization treatment of different parts of the sleeve 26 and is convenient to use.

[0037] Regarding the arrangement of the moving rod 2 on the working box 1 , a horizontally arranged frame 13 may be fixedly provided inside the working box 1 , and the moving rod 2 may be horizontally slidably mounted on the frame 13 .

[0038] Regarding the setting of the measuring component mentioned above, the measuring component includes a magnetic field meter 6, which is movably set on the bottom inner wall of the working box 1 and located below the energized coil 5; after the energized coil 5 moves to a specified position close to the sleeve 26, the magnetic field meter 6 will also move to the corresponding position below the sleeve 26. During the process of the energized coil 5 magnetizing the sleeve 26, the magnetic field meter 6 can measure and process the sleeve 26. When the measured magnetic field strength reaches the predetermined magnetic field strength, the sleeve 26 stops rotating, that is, the magnetization process is stopped.

[0039] Furthermore, the measuring assembly also includes a one-way threaded rod 21 and a synchronous motor 22. The one-way threaded rod 21 is arranged horizontally and rotatably mounted on the bottom inner wall of the working box 1. The synchronous motor 22 is arranged at the bottom of the working box 1, and the output shaft of the synchronous motor 22 is fixedly connected to the one-way threaded rod 21. A chute 23 is provided on the bottom inner wall of the working box 1, and a support rod 24 is slidably mounted on the chute 23. The support rod 24 is threadedly sleeved on the one-way threaded rod 21, and the magnetic field measuring instrument 6 is fixedly mounted on the support rod 24. By driving the synchronous motor 22 to work, the one-way threaded rod 21 can be rotated, and the magnetic field measuring instrument 6 can be moved to a specified position and synchronized with the energized coil 5.

[0040] As shown in Figures 1 and 3, for the setting of the above-mentioned clamping assembly, the clamping assembly is arranged on the working box body 1, and the clamping assembly is used to clamp and fix the sleeve 26 between the energized coil 5 and the magnetic field measuring instrument 6; specifically, the clamping assembly includes a load-bearing bracket 16 and a drive motor 17, the load-bearing bracket 16 is fixedly arranged on the working box body 1, the drive motor 17 is fixedly installed on the load-bearing bracket 16, the output shaft of the drive motor 17 is fixedly provided with a storage seat 18, and two clamping jaws 20 are slidably installed on the storage seat 18, a bidirectional threaded rod 19 is rotatably installed on the storage seat 18, and the bidirectional threaded rod 19 has two threaded sections with opposite threads, one end of the two clamping jaws 20 is respectively threadedly sleeved on the two threaded sections, and the two clamping jaws 20 are used to clamp and fix the sleeve 26. The two-way threaded rod 19 can be used to drive the two clamping jaws 20 to move closer to each other, thereby achieving the clamping and fixation of the sleeve 26. After the energized coil 5 moves to a specified position close to the sleeve 26, the drive motor 17 can be activated, and the drive motor 17 can drive the storage seat 18 to rotate, thereby achieving the rotation of the sleeve 26. The energized coil 5 can perform circumferential magnetization on the sleeve 26.

[0041] In order to prevent the drive motor 17 from no longer driving the sleeve 26 to rotate after the sleeve 26 is magnetized to a preset magnetic field strength, the present invention can also fix a controller 25 inside the working box 1, and the magnetic field measuring instrument 6 and the drive motor 17 are both electrically connected to the controller 25, and the drive motor 17 is controlled by the controller 25; after the magnetic field measuring instrument 6 detects that the magnetic field strength of the sleeve 26 during the magnetization process reaches a preset value, it will send a signal to the controller 25, and the controller 25 will control the drive motor 17 to stop after processing the signal, so that the drive motor 17 will no longer drive the sleeve 26 to rotate, that is, the energized coil 5 stops magnetizing the sleeve 26.

[0042] Regarding the configuration of the controller 25 in the present invention, the controller 25 can be any suitable computing device, such as a personal computer, a server, a programmable logic controller (PLC), a single-chip microcomputer, etc., or an integrated computer device. The controller 25 has functions such as receiving information and sending control commands. The controller 25 can control the drive motor 17 to perform corresponding actions through wired or wireless communication. At the same time, the configuration of the energized coil 5 in the present invention can be equivalently replaced with a U-shaped magnet, and the configuration of the magnetic field measuring instrument 6 in the present invention can also be equivalently replaced with other measurement technologies in the prior art.

[0043] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
