Description

Technical Field

[0001] The present application relates to the technical field of magnetizing devices, and in particular to a magnetizing head with integrated magnetizing flux detection. Background Art

[0002] The magnetizing head is a magnetizing device for magnetizing magnetic materials. It can magnetize magnetic parts and make the workspace magnetic.

[0003] In the related art, after the magnetization process is performed on the workpiece to be magnetized, it is necessary to perform corresponding magnetic flux detection on the magnetized workpiece to detect whether the magnetic flux of the magnetized workpiece reaches the specified parameters. During the detection, the magnetized workpiece that has completed the magnetization step needs to be placed on the magnetic flux detection device for detection, and then qualified magnetized workpieces are screened out.

[0004] In the above-mentioned related technologies, after the magnetizing head completes the magnetization of the workpiece to be magnetized, the magnetized workpiece needs to be transported to the magnetic flux detection device for detection, which increases the waiting time in the middle and is not conducive to improving the overall work efficiency. Utility Model Content

[0005] In order to shorten the time spent on magnetizing and detecting magnetic flux of magnetic workpieces and improve work efficiency, the present application provides a magnetizing and magnetic flux detection integrated magnetizing head.

[0006] The present application provides a magnetizing flux detection integrated magnetizing head adopting the following technical solution:

[0007] A magnetizing head integrated with magnetizing flux detection, comprising:

[0008] The base is provided with a power connector for connecting to an external power source;

[0009] An iron core is fixed on the base, the iron core is connected to the power connector and is used to transmit current, and the iron core is provided with a placement slot for placing the workpiece;

[0010] A magnetizing coil connected to the iron core and arranged around the placement slot to generate a magnetizing magnetic field;

[0011] The magnetic flux detection coil is connected to the iron core and is arranged around the placement groove to detect the magnetic flux of the workpiece.

[0012] By adopting the above technical solution, after the workpiece enters the placement slot, it is magnetized by the magnetization coil, and then the workpiece magnetic flux is detected by the flux detection coil, so that the workpiece can be subjected to flux detection immediately after the magnetization is completed, which helps to shorten the time of magnetization and flux detection of the workpiece and improve processing efficiency.

[0013] Optionally, it also includes a water cooling component, which is arranged around the outer wall of the core and circulates water around the outer wall of the core.

[0014] By adopting the above technical solution, when the water cooling component is arranged around the outer wall of the iron core, the water flow is used to absorb and dissipate the heat generated during the operation of the iron core, so that the iron core is not prone to excessive temperature during continuous operation, thereby not easily damaging the magnetization coil and the flux coil.

[0015] Optionally, the water cooling assembly includes a sealing cover and a water flow valve. The sealing cover forms a water flow chamber when it is arranged on the outer wall of the core. The water flow valve is fixed on the outer wall of the sealing cover and communicates with the water flow chamber.

[0016] By adopting the above technical solution, the sealing cover and the water flow valve cooperate with each other so that the water flow can circulate into the sealing cover, so that the water flow can circulate in the water flow chamber to take away the dissipated heat, which helps to improve the cooling effect.

[0017] Optionally, the water flow valve includes a water inlet valve and a water outlet valve, and the water inlet valve and the water outlet valve are evenly arranged on the circumference of the sealing cover, the water inlet valve supplies water to flow into the water flow chamber, and the water outlet valve supplies water to flow out.

[0018] By adopting the above technical solution, the water inlet valve and the water outlet valve cooperate with each other, so that water can enter the water flow cavity and then quickly flow out from the water outlet valve, so that the water flow has higher fluidity and achieves good heat dissipation.

[0019] Optionally, at least two of the magnetizing coils and the magnetic flux detection coils are provided, and at least two of the magnetizing coils and the magnetic flux detection coils are arranged at intervals in an insertion direction of the workpiece into the placement slot.

[0020] By adopting the above technical solution, when at least two magnetizing coils and magnetic flux detection coils are arranged at intervals, the magnetizing coils can form a balanced magnetic field, which helps to improve the magnetization efficiency of the workpiece. In addition, when the magnetic flux detection coils are arranged at intervals, magnetic flux detection can be performed on the workpiece from both sides, which helps to improve detection sensitivity and accuracy.

[0021] Optionally, a guide piece is embedded in a groove side wall of the placement groove away from the base, and the guide piece is provided with a guide groove, which is concentrically arranged with the placement groove, and the guide groove is used for embedding and limiting the workpiece.

[0022] By adopting the above technical solution, the setting of the guide member allows the workpiece to be in a position concentric with the placement groove when placed in the guide groove, so that the magnetizing coil can act evenly on the workpiece when generating the magnetizing magnetic field, which helps to improve the magnetization effect.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. After the workpiece enters the placement slot, it is magnetized by the magnetization coil, and then the magnetic flux of the workpiece is detected by the magnetic flux detection coil. Therefore, the magnetic flux detection work is carried out immediately after the workpiece is magnetized, which helps to shorten the time of magnetization and magnetic flux detection of the workpiece and improve the processing efficiency;

[0025] 2. When the water cooling assembly is arranged around the outer wall of the core, the water flow is used to absorb and dissipate the heat generated during the operation of the core, so that the core is not likely to generate excessively high temperature during continuous operation, thereby not easily damaging the magnetizing coil and the flux coil;

[0026] 3. When at least two magnetizing coils and magnetic flux detection coils are arranged at intervals, the magnetizing coils can form a balanced magnetic field, which helps to improve the magnetization efficiency of the workpiece. In addition, when the magnetic flux detection coils are arranged at intervals, magnetic flux detection can be performed on the workpiece from both sides, which helps to improve detection sensitivity and accuracy.

[0030] The following is combined with Figure 1-2 In this embodiment, the direction indicated by the coordinate axis z in the figure is up, and the direction opposite to the z axis is down. The z axis is only used as a direction reference and is not used as a direction limitation in actual use.

[0031] The present application embodiment discloses a magnetizing head with integrated magnetizing flux detection. Figure 1 and Figure 2The magnetizing and flux detection integrated magnetizing head comprises a base 1, an iron core 2, a magnetizing coil 3 and a flux detection coil 4. The base 1 is electrically connected to an external power supply. An iron core 2 is fixedly arranged on the upper surface of the base 1. A placement groove 21 is provided on the upper side wall of the iron core 2 for the workpiece to be placed. The magnetizing coil 3 and the flux detection coil 4 are both fixedly arranged on the inner side wall of the placement groove 21. When working, the magnetizing coil 3 generates electromagnetic induction to realize magnetization of the workpiece. When the magnetization is completed, the workpiece will generate a weak current in the magnetic field. The flux detection coil 4 detects the current change to know whether the workpiece is a qualified product. Therefore, there is no need to remove the workpiece after the magnetization process is completed, and the flux detection work can be carried out, which shortens the overall processing time of the workpiece.

[0032] It should be further explained that, in the present embodiment, the workpiece being processed is a motor rotor, and the shape of the placement slot 21 is adapted to the outer shape of the workpiece, so that when the workpiece is inserted from top to bottom, a limit can be formed on the circumference of the workpiece.

[0033] Reference Figure 2 A guide member 6 is embedded in the slot of the placement slot 21. The guide member 6 is arranged in a disc shape. A guide convex ring 61 is extended downward from the center of the guide member 6. The guide convex ring 61 is arranged coaxially with the guide member 6 to form a guide slot 611. When the workpiece is placed in the guide convex ring 61, the inner wall of the guide slot 611 guides the workpiece, so that the workpiece is in a coaxial position with the iron core 2 when entering the placement slot 21, so that the workpiece can receive a uniform electromagnetic field force during the magnetization process.

[0034] Reference Figure 2 , the number of the magnetizing coils 3 and the number of the magnetic flux detection coils 4 are both at least two. In the present embodiment, an example is given in which two magnetizing coils 3 and two magnetic flux detection coils 4 are both provided. Each magnetizing coil 3 and magnetic flux coil form a group, one group of magnetizing coils 3 is arranged on the inner wall of the placement slot 21 close to the upper notch, and the other group is arranged on the inner wall of the notch of the placement slot 21 close to the lower side, so that during magnetization, a uniform magnetic field force can be provided in the vertical direction, as well as a more sensitive magnetic flux detection effect.

[0035] Reference Figure 1 The upper surface of the base 1 is also provided with a power connector 11, which is electrically connected to an external power source so that the external power source can provide power to the magnetizing coil 3 and the magnetic flux detection coil 4. During installation, an electrical connection is formed between the power source and the iron core 2, and the magnetizing coil 3 and the magnetic flux detection coil 4 are both electrically connected to the iron core 2.

[0036] Reference Figure 1 and Figure 2The outer wall of the iron core 2 is also provided with a water cooling assembly 5 for cooling the heat dissipated from the iron core 2. Specifically, the water cooling assembly 5 includes a sealing cover 51 and a water flow valve 52. The sealing cover 51 is provided on the horizontal outer wall of the iron core 2, so that a water flow chamber 511 is formed between the sealing cover 51 and the outer wall of the iron core 2. The water flow valve 52 includes an inlet valve 521 and an outlet valve 522. The inlet valve 521 and the outlet valve 522 are symmetrically arranged on the outer side of the sealing cover 51, and the inlet valve 521 and the outlet valve 522 are both connected to the water flow chamber 511. The water flow is circulated from the inlet valve 521 into the water flow chamber 511 and then output from the outlet valve 522. In this embodiment, the inlet valve 521 and the outlet valve 522 are both one-way valves.

[0037] The implementation principle of the integrated magnetizing and flux detection magnetizing head in the embodiment of the present application is as follows: when working, the workpiece is placed in the placement slot 21, and the workpiece is magnetized by the magnetizing coil 3. After the magnetization is completed, the flux detection coil 4 performs flux detection when the workpiece is removed, which can shorten the time spent on magnetizing and flux detection of the workpiece.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
