Description

Technical Field

[0001] The present invention relates to the technical field of fixtures, and particularly to a three-dimensional rotary magnetizing fixture. Background Art

[0002] A three-dimensional rotary magnetizing fixture is a device used for magnetizing magnetic materials, mainly used in industry and laboratories to effectively magnetize magnetic materials. The three-dimensional design allows the fixture to rotate freely in multiple directions, enabling the magnetized material to receive the magnetic field at different angles, thereby ensuring the uniformity and effectiveness of magnetization.

The magnetizing fixture includes a substrate, on the surface of which there is a circular groove for accommodating the magnetic sheet. Radially of the circular groove on the surface of the substrate, there are four evenly distributed grooves, and in each groove, there is a cylinder adapted thereto.

A sensor for detecting the displacement of the piston rod provided therein is provided on the side wall of the groove, and the sensor can transmit a signal to the control unit.

[0004] Currently, when magnetizing a tubular magnetic material, since the part of the clamping member in most existing three-dimensional rotary magnetizing fixtures that fixes the tubular magnetic material is simply a positioning groove, and the length of the positioning groove is fixed and cannot be adjusted according to the length of the tubular magnetic material. When the tubular magnetic material is too long or too short, the distance between the two clamping members cannot be adjusted as needed, thus reducing the practicality of the three-dimensional rotary magnetizing fixture.

[0005] Therefore, we propose a three-dimensional rotary magnetizing fixture to solve the problems raised above. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When it is necessary to magnetize a tubular magnetic material using a three-dimensional rotary magnetization fixture, first adjust the vertical distance between the second fixture and the first fixture according to the length of the tubular magnetic material to match the length of the tubular magnetic material.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figure 1-8 , the present invention provides a technical solution: a three-dimensional rotary magnetization fixture, including a compression plate 1, a magnetization assembly 2 is arranged near the center at the top of the compression plate 1, a clamping assembly 3 is arranged at the top of the compression plate 1, the clamping assembly 3 includes two limit rods 301, multi-stage electric telescopic rods 302 are arranged at the tops of the two limit rods 301, a lifting frame 303 is fixedly installed between the tops of the two multi-stage electric telescopic rods 302, a first fixture 304 is fixedly installed on the inner top surface of the lifting frame 303, a positioning rod 305 is movably connected inside the first fixture 304, a second fixture 306 is movably sleeved on the outer surface of the positioning rod 305, a Hall sensor 307 is arranged on the outer surface of the first fixture 304, a servo motor 308 is fixedly installed near one side edge at the top of the lifting frame 303 through screws, the output end of the servo motor 308 is fixedly connected with a lead screw 309, the bottoms of the two limit rods 301 are fixedly connected with the top of the compression plate 1, the top of the positioning rod 305 movably penetrates to the outside of the first fixture 304, the bottom end of the lead screw 309 sequentially movably penetrates through the lifting frame 303 to the outside of the first fixture 304, and the outer surface of the lead screw 309 is in threaded connection with the inside of the second fixture 306.

[0033] In this embodiment, when it is necessary to magnetize the tubular magnetic material using the three-dimensional rotary magnetization fixture, first, the servo motor 308 is started according to the length of the tubular magnetic material to drive the lead screw 309 to rotate, and then drive the second fixture 306 to move up or down until the vertical distance between the second fixture 306 and the first fixture 304 matches the length of the tubular magnetic material. Among them, the positioning rod 305 plays a role in limiting the second fixture 306, so that it can only move vertically up and down and cannot rotate. Then, the pipe object can be inserted into the round holes in the first fixture 304 respectively, so that the bottom end of the tubular magnetic material is inserted into the round hole in the second fixture 306 to the bottom of the round hole. Among them, as Figure 7 shown, the round holes in the first fixture 304 and the second fixture 306 are in one-to-one correspondence. The purpose is to facilitate the support and limitation of the pipe object. After multiple tubular magnetic materials are placed, the two multi-stage electric telescopic rods 302 can be started through the controller 202 to shorten them, drive the lifting frame 303 to move downward, and then drive the first fixture 304 and the second fixture 306 to move downward to between the outer surfaces of the first coil 207 and the second coil 209, so as to magnetize the tubular magnetic material. When the magnetization of the tubular magnetic material is completed, the two multi-stage electric telescopic rods 302 are started again to make them extend, drive the lifting frame 303 to move upward, so as to move the first fixture 304 and the second fixture 306 upward to the outside of the magnetization assembly 2. Then, the servo motor 308 can be started again to drive the lead screw 309 to rotate, and then drive the second fixture 306 to move upward, so as to drive the bottom of the tubular magnetic material to move upward, which is convenient for the staff to take out the magnetized tubular magnetic material. Through the action of the clamping assembly 3, the three-dimensional rotary magnetization fixture can adjust the distance between the two clamping members according to the length of the tubular magnetic material, increasing the practicability of the fixture, and solving the problem that most vertical magnetization fixtures in the prior art cannot adjust the distance between the clamping members according to the length of the tubular magnetic material, reducing the practicability.

[0034] As Figures 1-5As shown in the figure, a three-dimensional rotary magnetization fixture includes a compression plate 1. A magnetization assembly 2 is arranged near the center at the top of the compression plate 1. A clamping assembly 3 is arranged at the top of the compression plate 1. The clamping assembly 3 includes two limiting rods 301. Multi-stage electric telescopic rods 302 are arranged at the tops of the two limiting rods 301. A lifting frame 303 is fixedly installed between the tops of the two multi-stage electric telescopic rods 302. A first clamp 304 is fixedly installed on the inner top surface of the lifting frame 303. A positioning rod 305 is movably connected inside the first clamp 304. A second clamp 306 is movably sleeved on the outer surface of the positioning rod 305. A Hall sensor 307 is arranged on the outer surface of the first clamp 304. The magnetization assembly 2 includes a base 201. The bottom of the base 201 is fixedly connected to the top of the compression plate 1. A controller 202 is arranged on the outer surface of the base 201. A limiting groove 203 is opened near the center at the top of the base 201. A rotating shaft 204 is rotatably connected inside the limiting groove 203. The top of the rotating shaft 204 movably penetrates to the outside of the limiting groove 203. A driven gear 205 is fixed at the top of the rotating shaft 204. A first fixing disk 206 is fixed near the outside at the top of the driven gear 205. A first coil 207 is arranged on the inner wall of the first fixing disk 206. A second fixing disk 208 is fixed near the inside at the top of the driven gear 205. A second coil 209 is arranged on the outer surface of the second fixing disk 208. A driving motor 210 is arranged at the top of the compression plate 1. The output end of the driving motor 210 is fixedly connected to a driving shaft 211. A driving gear 212 is fixed at the top of the driving shaft 211. The outer surface of the driving gear 212 is meshed with the outer surface of the driven gear 205.

[0035] In this embodiment, after the tubular magnetic material is positioned, the external power supply can be electrically connected to the first coil 207 and the second coil 209. According to Ampere's law, when an electric current passes through the coil, a magnetic field will be generated around the coil. When the coil is energized, the formed magnetic field is around the coil, and the magnetic field lines show a direction from one end point of the coil to the other end point. When the tubular magnetic material to be magnetized is placed inside the coil, the magnetic field will penetrate into the material. Under the action of the external magnetic field, the tiny magnetic domains inside the material start to align. During the magnetization process, as the applied magnetic field strength increases, the magnetic domains of the material gradually change from a random distribution state to a unified direction, so that the tubular magnetic material itself also obtains magnetism and generates a magnetic field respectively. At the same time, the driving motor 210 is started through the controller 202 to drive the driving shaft 211 to rotate, and then drive the driving gear 212 to rotate, so that the driven gear 205 rotates. Among them, as Figure 5As shown, the cross-section of the rotating shaft 204 matches the cross-section of the limiting groove 203, both of which are T-shaped. The purpose is to limit the rotating shaft 204 while facilitating its rotation. The rotation of the driven gear 205 drives the rotation of the first fixed disk 206 and the second fixed disk 208, and then drives the rotation of the first coil 207 and the second coil 209 respectively, so as to magnetize the tubular magnetic material arranged between the first coil 207 and the second coil 209 in all directions. At the same time, the Hall sensor 307 is started through the controller 202, and the magnetization effect of the tubular magnetic material is detected through the Hall sensor 307. Among them, when the object is magnetized, the generated magnetic field nearby will affect the Hall sensor 307. When an external magnetic field is detected, the current inside the Hall sensor 307 will be affected, so as to generate a certain Hall voltage signal at the output end of the sensor. The Hall voltage output by the Hall sensor 307 is proportional to the detected magnetic field strength. By amplifying and processing this voltage signal, the magnetic field strength of the tubular magnetic material can be measured. When the magnetic field strength in the tubular magnetic material reaches the required value, the first coil 207 and the second coil 209 are respectively disconnected from the external power supply. By rotating the coils, it is ensured that the magnetic field is evenly distributed around the tubular magnetic material, reducing the magnetization effect difference caused by the uneven magnetic field, thereby improving the uniformity of magnetization. In addition, through the rotational magnetization of the coils, the friction generated by the object to be magnetized in the vertical rotation magnetization fixture during the rotation process is effectively prevented.

[0036] Usage method and working principle of this device: When it is necessary to use the vertical rotation magnetization fixture to magnetize the tubular magnetic material, first start the servo motor 308 according to the length of the tubular magnetic material, drive the lead screw 309 to rotate, and then drive the second fixture 306 to move up or down until the vertical distance between the second fixture 306 and the first fixture 304 matches the length of the tubular magnetic material. Then the pipeline object can be inserted into the round holes in the first fixture 304 respectively, so that the bottom end of the tubular magnetic material is inserted into the round hole in the second fixture 306 to the bottom of the round hole, as Figure 7As shown, the round holes in the first fixture 304 and the second fixture 306 correspond one by one. After multiple tubular magnetic materials are placed, the controller 202 can be used to start the two multi-stage electric telescopic rods 302, causing them to shorten, driving the lifting frame 303 to move downward, and then driving the first fixture 304 and the second fixture 306 to move downward to between the outer surfaces of the first coil 207 and the second coil 209. Then, the external power supply can be electrically connected to the first coil 207 and the second coil 209. According to Ampere's law, when an electric current passes through a coil, a magnetic field will be generated around the coil. When the coil is energized, the formed magnetic field surrounds the coil, and the magnetic field lines show a direction from one end of the coil to the other end. When the tubular magnetic material to be magnetized is placed inside the coil, the magnetic field will penetrate into the material. Under the action of the external magnetic field, the tiny magnetic domains inside the material begin to align. During the magnetization process, as the applied magnetic field strength increases, the magnetic domains of the material gradually change from a random distribution state to a unified direction, so that the tubular magnetic material itself also obtains magnetism, generating magnetic fields respectively. At the same time, the controller 202 is used to start the drive motor 210, driving the drive shaft 211 to rotate, and then driving the driving gear 212 to rotate, so that the driven gear 205 rotates, and then driving the first fixed disk 206 and the second fixed disk 208 to rotate, respectively driving the first coil 207 and the second coil 209 to rotate, and then magnetizing the tubular magnetic materials arranged between the first coil 207 and the second coil 209 in all directions. At the same time, the controller 202 is used to start the Hall sensor 307, and the magnetization effect of the tubular magnetic material is detected through the Hall sensor 307. When the magnetic field strength in the tubular magnetic material reaches the required value, the first coil 207 and the second coil 209 can be disconnected from the external power supply respectively. By rotating the coils, it is ensured that the magnetic field is evenly distributed around the tubular magnetic material, reducing the difference in magnetization effect caused by uneven magnetic field, thereby improving the uniformity of magnetization. In addition, through the rotational magnetization of the coils, it effectively prevents the object to be magnetized in the vertical rotational magnetization fixture from generating friction during the rotation process. After the magnetization of the tubular magnetic material is completed, the two multi-stage electric telescopic rods 302 are started again, causing them to extend, driving the lifting frame 303 to move upward, thereby moving the first fixture 304 and the second fixture 306 upward to the outside of the magnetization assembly 2. Then, the servo motor 308 can be started again, driving the lead screw 309 to rotate, and then driving the second fixture 306 to move upward, thereby driving the bottom of the tubular magnetic material to move upward, facilitating the staff to take out the magnetized tubular magnetic material. Among them, the controller 202 is electrically connected to the drive motor 210, the multi-stage electric telescopic rod 302, the Hall sensor 307, and the servo motor 308.

[0037] The wiring diagrams of the controller 202, drive motor 210, multi-stage electric telescopic rod 302, Hall sensor 307, and servo motor 308 in the present invention belong to the common knowledge in the art. Their working principles are already well-known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the controller 202, drive motor 210, multi-stage electric telescopic rod 302, Hall sensor 307, and servo motor 308 will not be explained in detail.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
