Description

Technical Field

[0001] The utility model relates to the field of NdFeB production, in particular to a positioning device used for NdFeB production. Background Art

[0002] NdFeB, in simple terms, is a kind of magnet. Unlike the magnets we usually see, it is called the "king of magnets" because of its excellent magnetic properties. NdFeB contains a large amount of rare earth elements, neodymium, iron and boron. It is hard and brittle. The advantages of NdFeB are high cost performance and good mechanical properties; the disadvantages are low operating temperature, poor temperature characteristics, and easy powdering and corrosion. It must be improved by adjusting its chemical composition and taking surface treatment methods to meet the requirements of practical applications. In the production process of NdFeB, it needs to be clamped and positioned.

[0003] In a Chinese patent, a rapid positioning device for the production of NdFeB strong magnets is disclosed, and its patent number is CN217703111U. In the patent, a rapid positioning device for the production of NdFeB strong magnets includes a base, a threaded rod is movably connected to the surface of the base, and slide plates are threadedly connected to both sides of the threaded rod, a first connecting plate is movably connected to the top of the slide plate, and a second connecting plate is movably connected to one side of the first connecting plate. A rapid positioning device for the production of NdFeB strong magnets, the threaded rod drives the two slide plates to move so that the first connecting plate and the second connecting plate are folded so that the two clamping plates move to clamp and fix the NdFeB, the structure is simple, the operation is convenient, and the NdFeB of different sizes can be clamped and fixed, thereby improving the applicability of the device. The clamping plate can use the first spring to buffer the clamping plate during the movement, and the second gear is smaller than the first gear, which can reduce the rotation speed of the threaded rod, thereby facilitating the control of the clamping force of the NdFeB and avoiding excessive clamping force affecting the surface structure of the NdFeB.

[0004] The above-mentioned published patents have the following disadvantages:

[0005] (1) In the prior art, after the NdFeB material is fixed by a device, some corners are sometimes inconvenient to operate, which affects the production efficiency of the NdFeB material.

[0006] (2) In the prior art, the size and shape of NdFeB materials vary during production, resulting in the inability of existing devices to stably fix them on the surface of the device. During production, there is a gap between the NdFeB material and the fixture, which may cause sliding.

[0007] (3) After the fixing fixture in the prior art fixes the NdFeB material, it needs to be processed at different angles during production. If the NdFeB material is to be rotated, the entire device needs to be rotated, which is a complicated process. Utility Model Content

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] like Figures 1 to 5 As shown, a positioning device for NdFeB production includes a table top 1, a circular cavity is provided inside the table top 1 and supported by a support leg 101 installed on the bottom surface, and a rotating block 2 rotates inside the cavity. Under the control of a knob 203, the rotating rod 201 can drive the rotating block 2 to rotate, and a straight groove 301 is provided on a support plate 3 fixed above the rotating block 2 to drive the upper fixed cylinder 4 to move through a slider 303 sliding inside the support plate 3, and a cavity is provided inside the fixed cylinder 4 to fix a clamping assembly 5, and the clamping assembly 5 is provided with a driving motor 501, which drives a bidirectional screw 502 to rotate, so that a linkage ring 503 threadedly connected to the surface of the bidirectional screw 502 can drive a clamping head 6 on one end surface thereof to move through a moving block 504, so as to fix the NdFeB material.

[0032] The surface of the rotating rod 201 is connected to a limiting ring 202 fixed to the bottom surface of the table 1 , and an inserting rod 204 is arranged between the limiting ring 202 and the rotating rod 201 .

[0033] Through the above technical solution, after the knob 203 controls the rotating rod 201 to rotate to a suitable position, the insert rod 204 can be used to fix the rotating rod 201 and the limiting ring 202, thereby limiting the rotation angle of the rotating block 2.

[0034] An adjusting hole 302 is arranged inside the straight groove 301 to cooperate with a limiting rod 304 inside the straight groove 301 to limit the slider 303 , and a control member 305 that slides on the surface of the fixed cylinder 4 is fixed at one end of the limiting rod 304 .

[0035] Through the above technical solution, by controlling the operating member 305, the limiting rod 304 can be inserted into the inner side of the adjustment hole 302 at different positions to limit the slider 303, so as to facilitate the adjustment of the fixed position of the NdFeB.

[0036] The moving block 504 slides on the surface of the fixed cylinder 4 .

[0037] Through the above technical solution, the moving block 504 is moved by the limiting ring 202, and the fixed cylinder 4 can limit the moving block 504 to prevent the limiting ring 202 from rotating together with the bidirectional screw 502 during its rotation.

[0038] A groove 601 is provided on the inner side of the clamping head 6 to install the limit block 602 , and a screw rod 1 603 is fixed on the surface of the limit block 602 . The screw rod 1 603 is threadedly connected to the inner side of a screw barrel 604 controlled by a screw rod 2 605 .

[0039] Through the above technical solution, under the control of screw 2 605, the screw barrel 604 can rotate, so that the screw 1 603 connected to its inner side thread is limited by the limit block 602, so that the screw 1 603 is separated from the screw barrel 604 and the clamping head 6 is replaced.

[0040] The limit block 602 slidably connected to the inner side of the groove 601 is driven by the screw rod 1 603 , and the screw barrel 604 and the screw rod 2 605 rotate inside the clamping head 6 .

[0041] Through the above technical solution, the screw barrel 604 and the screw 2 605 rotating inside the clamping head 6 can drive the screw 1 603 to push the limit block 602 to move through the threaded structure, thereby realizing the separation of the clamping head 6 and the moving block 504.

[0042] When in use, when the user uses the positioning device produced by NdFeB, the NdFeB to be produced and processed is placed on the top of the fixed cylinder 4, and the screw rod 2 605 is rotated to make the screw cylinder 604 rotate accordingly, so that the screw rod 1 603 inside it can drive the limit block 602 to slide inside the groove 601, so as to separate the clamping head 6 from the moving block 504, replace the clamping head 6 with a suitable one, start the driving motor 501, so that the bidirectional screw rod 502 can rotate, thereby driving the linkage ring 503 to move the movable block 504. The movable block 504 slides on the surface of the fixed tube 4 and fixes the NdFeB through the clamping head 6. According to the needs of the operator, the control piece 305 is pushed upward to allow the insertion rod 204 to be separated from the inner side of the adjustment hole 302, so that the slider 303 is used to slide on the inner side of the straight groove 301 to adjust the position of the fixed tube 4 laterally. At the same time, the insertion rod 204 is pulled out, and the rotation of the rotating rod 201 is controlled by the knob 203, so that the rotating block 2 can drive the support plate 3 to rotate and adjust the orientation angle of the NdFeB material.
