Description

Technical Field

[0001] This application relates to the field of magnet testing equipment, and more particularly to a magnetic force testing device for magnet production. Background Technology

[0002] An electromagnet is a device that generates electromagnetism by passing an electric current through it. A conductive winding, matched to the power of the current, is wound around an iron core, making the current-carrying coil magnetic like a magnet. The iron core is usually shaped like a horseshoe to make it easier to magnetize.

[0003] After the electromagnet is manufactured, it needs to be tested. The test is usually done using a teslameter. When the electromagnet is energized, it generates a magnetic field. By inserting the probe of the teslameter into the cavity of the electromagnet, the teslameter can detect the magnetic induction intensity of the electromagnet. During the test, the user needs to move the probe of the teslameter multiple times to detect the magnetic field at multiple locations inside the electromagnet, thereby judging the overall production quality of the electromagnet.

[0004] The aforementioned technical solutions have the following drawbacks: when moving the probe of the Tesla meter, the error is relatively large due to the manual movement of the Tesla meter by the user. During the test, the probe of the Tesla meter needs to be kept stationary for a long time, which is inconvenient to operate and results in a large test error. Utility Model Content

[0005] To reduce the error in detecting the magnetic field of an electromagnet, this application provides a magnetic force testing device for magnet production.

[0006] The magnetic force testing equipment for magnet production provided in this application adopts the following technical solution: A magnetic force testing device for magnet production includes a teslameter, a displacement mechanism, a worktable, and a testing rod. The teslameter is mounted on the testing rod, which is horizontally mounted on the displacement mechanism. The displacement mechanism is used to control the movement of the testing rod. The worktable is located on one side of the displacement mechanism and is used to place the electromagnet to be tested.

[0007] By adopting the above technical solution, by installing a detection rod on the displacement mechanism, the displacement mechanism drives the detection rod to move, thereby enabling the detection rod to move the Tesla meter and maintain a stable position. This results in high accuracy of the moving distance of the Tesla meter when it is detected by the electromagnet, and low error during the detection process.

[0008] Optionally, the Tesla meter includes a body and an end head, the end head being connected to the body via a wire, the end head being mounted on the end of the detection rod, and the body being mounted on the detection rod.

[0009] By adopting the above technical solution, the body and end of the Tesla meter are connected by wires, allowing the end to be installed at the end of the detection rod. This results in a smaller cross-sectional area at the end of the detection rod, which can be inserted into a small cavity in the electromagnet, making it convenient to use.

[0010] Optionally, the displacement mechanism includes a first mounting plate, a first slide rail, a second mounting plate, a second slide rail, and a slide table. The second slide rail is horizontally set on the ground, the slide table is slidably connected to the second slide rail, the second mounting plate is slidably connected to the slide table, the first slide rail is fixed to the second mounting plate, the first mounting plate is slidably connected to the first slide rail, and the detection rod is mounted on the first mounting plate.

[0011] By adopting the above technical solution, by sliding the mounting plate one in the slide rail one and sliding the slide table on the slide rail two, the mounting plate one can slide vertically back and forth in the slide rail one through the ball screw, the mounting plate two can slide horizontally on the slide table, and the slide table can slide on the slide rail two, which further facilitates the user to control the movement of the Tesla meter's end.

[0012] Optionally, a placement rack is provided on the workbench. The placement rack is a circular plate structure and is horizontally set and rotatably connected to the workbench.

[0013] By adopting the above technical solution, and by setting up a placement rack on the workbench, the electromagnet to be tested can be placed on the placement rack. By rotating the placement rack, the user can quickly rotate the electromagnet, so that the end of the teslameter can cover a larger detection range, further improving the detection efficiency.

[0014] Optionally, the placement rack is provided with scale lines spaced equidistantly along the circumference.

[0015] By adopting the above technical solution, and by setting scale lines on the placement frame at equal intervals around the circumference of the placement frame, it is convenient for users to check the rotation range of the placement frame and the electromagnet, and to control the rotation of the placement frame.

[0016] Optionally, the workbench is equipped with a driving component, which is used to drive the placement rack to rotate.

[0017] By adopting the above technical solution, and by setting a driving component on the workbench, the driving component can drive the placement rack to rotate in both directions.

[0018] Optionally, the detection mechanism includes a ball bearing and a frame, with a groove on the detection rod, the ball bearing disposed on the groove, and the frame rotatably connected to the ball bearing.

[0019] By adopting the above technical solution, a groove is opened on the detection rod, and a ball is set in the groove. When the detection rod is tilted, the ball slides in the groove. When the detection rod is kept horizontal, the ball remains stationary at any position in the groove. This makes it convenient for users to check the levelness of the detection rod and reduces measurement errors.

[0020] Optionally, the frame is equipped with ropes and counterweights, with one end of the rope fixed to the counterweight and the other end fixed to the frame.

[0021] By adopting the above technical solution, a counterweight is installed on the frame to pull the rope, keeping the rope plumb, which makes it easier for users to check the horizontal status of the inspection rod.

[0022] In summary, the beneficial technical effects of this application are as follows: 1. By installing a detection rod on the displacement mechanism, the displacement mechanism drives the detection rod to move, thereby enabling the detection rod to move the Tesla meter and maintain a stable position. This results in high accuracy of the moving distance and low error during the detection process when the Tesla meter is detected by the electromagnet. 2. By sliding the mounting plate one in the slide rail one and sliding the slide table on the slide rail two, the mounting plate one can slide vertically back and forth in the slide rail one via the ball screw, the mounting plate two can slide horizontally on the slide table, and the slide table can slide on the slide rail two, which further facilitates the user to control the movement of the Tesla meter's end. 3. By setting up a placement rack on the workbench, the electromagnet to be tested can be placed on the placement rack. By rotating the placement rack, the user can quickly rotate the electromagnet, so that the end of the teslameter can cover a larger detection range, further improving detection efficiency.

Detailed Implementation

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses a magnetic force testing device for magnet production, referring to... Figure 1 and Figure 2 The system includes a teslameter 1, a displacement mechanism 2, a worktable 3, and a detection rod 4. The teslameter 1 includes a body 11 and an end 12, with the end 12 connected to the body 11 via wires. The teslameter 1 is used to detect the magnetic induction intensity of a magnet. The detection rod 4 is horizontally positioned, with one end mounted on the displacement mechanism 2 and the other end connected to the end 12. The body 11 is fixed to the detection rod 4. The displacement mechanism 2 drives the detection rod 4 to reciprocate linearly in different directions, thereby controlling the movement of the end 12. The worktable 3 is located on one side of the displacement mechanism 2. The bent iron 6 to be tested is placed on the worktable 3, and the end 12 extends horizontally into the bent iron 6 through the detection rod 4, thereby detecting the magnetic induction intensity of the bent iron 6 and thus the production quality of the bent iron 6. The displacement mechanism 2 can precisely control the movement of the detection rod 4, enabling the end 12 to move accurately within the bent iron 6 and maintain a stable position when detecting magnetic induction intensity, thus improving the accuracy of the detection data.

[0029] Reference Figure 1 and Figure 2 The displacement mechanism 2 includes a mounting plate 21, a slide rail 22, a mounting plate 23, a slide rail 24, and a slide table 25. The slide rail 24 is horizontally positioned on the ground, and the slide table 25 is slidably connected to the slide rail 24. The mounting plate 23 is slidably connected to the slide table 25, and the sliding direction of the mounting plate 23 is perpendicular to the sliding direction of the slide table 25. The slide rail 22 is vertically fixed to the mounting plate 23. The mounting plate 21 is slidably connected to the slide rail 22, and the detection rod 4 is mounted on the mounting plate 21. The mounting plate 21 can reciprocate vertically within the slide rail 22 via a ball screw, and the mounting plate 23 can move horizontally on the slide table 25 via a ball screw. The slide table 25 can move horizontally on the slide rail 24 via a motor drive. The displacement mechanism 2 can drive the end head 12 to move linearly in three degrees of freedom, thereby increasing the detection range of the Tesla meter 1.

[0030] Reference Figure 1A placement frame 31, a disc structure, is mounted on the worktable 3 and is horizontally positioned on the worktable 3. The placement frame 31 is rotatably connected to the worktable 3 and is used to hold the bent iron 6. When the placement frame 31 rotates on the worktable 3, the bent iron 6 can rotate relative to the detection rod 4, thereby adjusting the position of the end 12 within the bent iron 6, facilitating user control of the end 12's position within the bent iron 6. The placement frame 31 has graduation lines 32, equidistantly spaced along its circumference. Users can rotate the placement frame 31 using the graduation lines 32 to improve the accuracy of moving the bent iron 6. A drive unit 33, which can be a motor, is located on the underside of the worktable 3 and drives the placement frame 31 to rotate.

[0031] Reference Figure 3 A groove 41 is provided on the upper side of the detection rod 4, and the length direction of the groove 41 is parallel to the length direction of the detection rod 4. A detection mechanism 5 is provided in the groove 41. The detection mechanism 5 includes a ball bearing 51, a frame 52, a rope 53, and a counterweight 54. The ball bearing 51 is rotatably connected to the frame 52, which is fitted onto the detection rod 4. The ball bearing 51 is positioned on the groove 41 with its axis of rotation relative to the frame 52 in a horizontal direction and perpendicular to the detection rod 4. One end of the rope 53 is fixed to the frame 52, and the other end is connected to the counterweight 54. When the detection rod 4 is kept horizontal, the ball bearing 51 remains stationary at any position in the groove 41. When the detection rod 4 is tilted, the ball bearing 51 slides in the groove 41, which facilitates the user to judge the horizontality of the detection rod 4. When the detection rod 4 is inserted into the bent iron 6, it can keep the end 12 perpendicular to the magnetic field, improving the detection accuracy.

[0032] The implementation principle of this application embodiment is as follows: by installing the Tesla meter 1 on the detection rod 4, the detection rod 4 is moved by the displacement mechanism 2, so that the end 12 of the Tesla meter 1 can be inserted into the bent iron 6 to be tested and kept stable. During the detection process, the end 12 is moved by the displacement mechanism 2, which can control the movement accuracy of the end 12 and achieve high detection accuracy.

[0033] 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.
