Abstract
Description
Technical Field
[0001] This utility model belongs to the field of clamping technology, and in particular to a clamping fixture for processing neodymium iron boron magnets. Background Technology
[0002] Neodymium iron boron (NdFeB) is an intermetallic compound composed of the rare earth elements neodymium, iron, and boron. In existing technologies, NdFeB magnets have characteristics such as high magnetic energy product and high magnetic saturation magnetic induction intensity, and are widely used in magnetic equipment, motors, transmission systems, etc. NdFeB magnets require processing during production, usually through a processing machine. The NdFeB magnets are placed in the processing chamber of the processing machine and then fixed with bolts for processing.
[0003] Current clamping fixtures for processing neodymium iron boron magnets can only process the unclamped side during operation. The other clamped parts need to be re-clamped and fixed by the operator before processing can be carried out, which reduces work efficiency.
[0004] Therefore, in view of this situation, there is an urgent need to design and produce a clamping fixture for processing neodymium iron boron magnets to meet the needs of practical use. Utility Model Content
[0005] The purpose of this invention is to provide a clamping fixture for processing neodymium iron boron magnets, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping fixture for processing neodymium iron boron magnets, comprising an electric clamp for clamping neodymium iron boron magnets and a first fixing plate, a second fixing plate fixedly connected to the upper side of the first fixing plate, a first telescopic rod installed on the side of the second fixing plate, a locking block fixedly connected to the extended end of the first telescopic rod, a third fixing plate fixedly connected to the upper side of the first fixing plate, a second motor installed on the side of the third fixing plate near the second fixing plate, and the output end of the second motor fixed to the electric clamp.
[0007] Preferably, the third fixing plate has a first groove on its side, and the side of the first groove engages with the locking block.
[0008] Preferably, a fixing rod is fixedly connected to the side of the first fixing plate, and a moving block is fixedly connected to the side of the fixing rod away from the first fixing plate.
[0009] Preferably, the movable block is slidably connected to a base on its side, and a first motor is mounted on the side of the base.
[0010] Preferably, the output end of the first motor is fixedly connected to a threaded shaft, and a movable block is screwed to the side of the threaded shaft.
[0011] Preferably, a fixed platform is fixedly connected to the upper side of the base, and a second telescopic rod is installed on the upper side of the fixed platform.
[0012] Preferably, the extended end of the second telescopic rod is fixedly connected to a workbench, and a limit plate is installed on the side of the workbench.
[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0014] This clamping fixture for processing neodymium iron boron magnets uses a first motor to drive a threaded shaft to rotate, which in turn moves a fixed rod, a first fixed plate, and an electric clamp to clamp the neodymium iron boron magnet placed on the worktable. When processing other parts, a second motor is started to drive the electric clamp to rotate. During rotation, a first telescopic rod is activated to move a locking block, which engages with a first groove, providing a limiting effect on the rotation of the electric clamp. After processing of the unclamped parts, the neodymium iron boron magnet is clamped by the electric clamp on the other side, which facilitates clamping of the processed parts and processing of the unprocessed parts, reducing manpower consumption.

[0021] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0022] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0023] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0024] To address the issue that during operation, only the unclamped sides can be processed, while processing of the clamped areas requires re-clamping and securing by the operator, resulting in reduced work efficiency, such as... Figures 1 to 3 The fixture shown includes an electric clamp 12 for processing neodymium iron boron magnets and a first fixed plate 6. A second fixed plate 7 is fixedly connected to the upper side of the first fixed plate 6. A first telescopic rod 8 is installed on the side of the second fixed plate 7. A locking block 9 is fixedly connected to the extended end of the first telescopic rod 8. A third fixed plate 10 is fixedly connected to the upper side of the first fixed plate 6. A second motor 11 is installed on the side of the third fixed plate 10 near the second fixed plate 7. The output end of the second motor 11 is fixed to the electric clamp 12. After the unclamped part is processed, the neodymium iron boron magnet is clamped by the electric clamp 12 on the other side, which facilitates clamping of the processed part and reduces manpower consumption. A first groove 13 is opened on the side of the third fixed plate 10. The side of the first groove 13 is engaged with the locking block 9. The locking block 9 makes the rotation of the electric clamp 12 90°, providing a limit for the rotation of the electric clamp 12.
[0025] A fixing rod 5 is fixedly connected to the side of the first fixing plate 6. A movable block 4 is fixedly connected to the side of the fixing rod 5 away from the first fixing plate 6. The movable block 4 has a threaded hole for easy screwing with the threaded shaft 3. A base 1 is slidably connected to the side of the movable block 4. A first motor 2 is installed on the side of the base 1. The output end of the first motor 2 is fixedly connected to the threaded shaft 3. The movable block 4 is screwed to the side of the threaded shaft 3. A fixing platform 14 is fixedly connected to the upper side of the base 1. A second telescopic rod 15 is installed on the upper side of the fixing platform 14. A worktable 16 is fixedly connected to the extended end of the second telescopic rod 15. A limit plate 17 is installed on the side of the worktable 16.
[0026] All structures and instruments are treated with heat-resistant and waterproof materials.
[0027] The first motor 2, the second motor 11, the electric clamp 12, and the second telescopic rod 15 are all conventional devices. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. They are all controlled by remote control switches. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0028] Working principle
[0029] In use, the clamping fixture for processing neodymium iron boron magnets starts the first motor 2 to drive the threaded shaft 3 to rotate. The rotation of the threaded shaft 3 drives the moving block 4 to move. The movement of the moving block 4 drives the fixed rod 5 to move. The electric clamp 12 clamps the neodymium iron boron magnet. When processing the neodymium iron boron magnet, the second motor 11 is started to process other positions. At the same time, the first telescopic rod 8 is started to drive the clamping block 9 to move and limit the electric clamp 12.
