[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figure 1 and Figure 2 As shown, a neodymium iron boron wire cutting fixture includes: a placement plate 20, which is a semi-capsule-shaped plate; a base block 21 is fixedly connected to the bottom of the placement plate 20; the base block 21 is a rectangular block; another placement plate 20 is also fixedly connected to the bottom of the base block 21; the two placement plates 20 on the upper and lower walls of the base block 21 are symmetrical to each other. This is existing technology and will not be described in detail here.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the conversion structure is set on the wall of the base block 21 to change the position of the symmetrical placement plates 20. The conversion structure includes: a rotating shaft 22, a frame 23, a limiting edge 30, a movable block 31, and a fixed plate 36. The rotating shaft 22 is fixedly connected to the side wall of the base block 21. The frame 23 is connected to the other end of the rotating shaft 22. The limiting edge 30 is symmetrically fixedly connected to the front and rear walls of each placement plate 20. The movable block 31 is slidably connected between each set of front and rear symmetrical limiting edges 30. The fixed plate 36 is fixedly connected to one side wall of each placement plate 20. The movable block 31, in conjunction with the fixed plate 36, can clamp the neodymium iron boron block.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the rotating shaft 22 is cylindrical, the frame 23 is an L-shaped plate, and a servo motor for driving the rotating shaft 22 is fixedly connected to one side of the frame 23. The end of the rotating shaft 22 is rotatably connected to the wall of the frame 23. The limiting edge 30 is a rod with an L-shaped cross section, and the movable block 31 is a right-angled trapezoidal block. The side wall plane of the movable block 31 faces the fixed plate 36, and a rectangular opening is provided on the inclined surface of the movable block 31. The conversion structure also includes a limiting groove 32, a limiting post 33, a stud 34, and a pressure block 35. The limiting groove 32 is a rectangular groove, and the limiting groove 32 is symmetrically opened on the front and rear wall surfaces of each movable block 31. The limiting post 33 is fixedly connected to the fixed plate. On the wall of the placement plate 20 at position 36 opposite to each other, the stud 34 is threadedly connected to the wall of the placement plate 20, the pressure block 35 is symmetrically rotated and connected to the wall of the stud 34, the movable block 31 can engage with each limiting groove 32, the stud 34 is cylindrical, the middle section of the stud 34 is threaded, the thread of the middle section of the stud 34 can be threadedly connected to the symmetrical placement plate 20, one side of the bottom of the pressure block 35 is inclined, the inclined surface of the pressure block 35 can contact the inclined surface of the movable block 31, the other side of the pressure block 35 can contact the wall of the limiting post 33, and the pressure block 35 can rotate on the wall of the stud 34;

[0030] In practical use, the NdFeB block to be clamped is first placed between the fixed plate 36 and the movable block 31 on the top of the uppermost placement plate 20. Then, the stud 34 is rotated. As the stud 34 rotates downward, it drives the pressure block 35 to move downward synchronously. As the pressure block 35 moves downward, its inclined surface gradually comes into contact with the inclined surface of the movable block 31. When the movable block 31 is pressed down and contacted by the pressure block 35, it can move along the symmetrical limiting edges 30 towards the fixed plate 36. After the movable block 31 and the fixed plate 36 have completely clamped the NdFeB block, wire cutting can be performed. After cutting is completed, the servo motor on the wall of the frame 23 is started. The motor drives the rotating shaft 22 to rotate half a turn. At this time, the base block 21 will be rotated by the rotating shaft 22, causing the positions of the upper and lower placement plates 20 to be reversed. The cut NdFeB will be located at the bottom, and the NdFeB block to be cut can be placed on the top of the empty placement plate 20 at the top. The pressure block 35 is controlled to slide downward in the same way, which drives the movable block 31 to cooperate with the fixed plate 36 to clamp the NdFeB block. As the stud 34 moves downward, the pressure block 35 below will move downward simultaneously. The movable block 31 that clamps the NdFeB block will unlock the position of the NdFeB below, and then the cut NdFeB below will fall downward. It can be collected before it falls, and this process is repeated.

[0031] In summary, by setting up a conversion structure, the two steps of unlocking the NdFeB position and installing the NdFeB can be completed simultaneously by changing the position of the placement plate 20, which originally required unlocking the NdFeB position. This effectively saves a lot of time and improves the efficiency of NdFeB wire cutting.

[0032] like Figure 3 As shown, multiple rectangular rods are fixedly connected to the wall surface of the movable block 31 facing the fixed plate 36, and multiple identical rectangular rods are also fixedly connected to the wall surface of the fixed plate 36 facing the movable block 31. The rectangular rods on the wall surface of the movable block 31 can be staggered with the rectangular rods on the wall surface of the fixed plate 36.

[0033] In practical use, the movable block 31 will drive the rectangular rod on its wall to contact and clamp the neodymium iron boron block in conjunction with the rectangular rod on the wall of the fixed plate 36;

[0034] In summary, by setting up the movable block 31 and the fixed plate 36, not only can it accommodate NdFeB blocks of different sizes, but it can also prevent NdFeB blocks from slipping and falling off through the rectangular rods on its walls.

[0035] Working principle: First, place the NdFeB block to be clamped between the fixed plate 36 and the movable block 31 on the top of the uppermost placement plate 20. Then, rotate the stud 34. As the stud 34 rotates downward, it drives the pressure block 35 to move downward synchronously. As the pressure block 35 moves downward, its inclined surface gradually comes into contact with the inclined surface of the movable block 31. When the movable block 31 is pressed down and contacted by the pressure block 35, it can move towards the fixed plate 36 along the symmetrical limiting edges 30. After the movable block 31 and the fixed plate 36 have completely clamped the NdFeB block, wire cutting can be performed. After cutting is completed, the servo motor on the wall of the frame 23 is started. The servo motor drives the rotating shaft 22 to rotate half a turn. At this time, the base block 21 will be rotated by the rotating shaft 22, causing the positions of the upper and lower placement plates 20 to be reversed. The cut NdFeB will be located at the bottom, and the NdFeB block to be cut can be placed on the top of the empty placement plate 20. The pressure block 35 is controlled to slide downward in the same way, which drives the movable block 31 to cooperate with the fixed plate 36 to clamp the NdFeB block. As the stud 34 moves downward, the pressure block 35 below will move downward synchronously. The movable block 31 holding the NdFeB block will unlock the position of the NdFeB below, and then the cut NdFeB below will fall downward. It can be collected before it falls.
