[0002] When producing permanent magnet motors, it is necessary to cut the iron core of the permanent magnet motor according to actual needs. When cutting, it is necessary to ensure the stability of the iron core, which is generally fixed by a locking clamp.

[0003] The current prior art CN212385079U discloses a core cutting and locking clamp for permanent magnet synchronous motor production, including a support frame and an iron core. The position of the limit block can be changed by changing the position of the adjusting rod in different inclined slots in the adjusting slot, thereby limiting the movable range of the first positioning block. The position of the second positioning block can be adjusted by the rotating rod. At the same time, the second positioning block and the rotating rod can slide relative to each other. When the core piece is locked and fixed, the position of the inclined slot where the adjusting rod is located is changed according to the size of the iron core, and the position of the second positioning block on the rotating rod is adjusted at the same time, so that the iron cores of different sizes can be locked and fixed, thereby solving the problem that the common clamps for locking the iron cores are difficult to lock and fix the iron cores of different sizes.

[0004] However, when using the above method, since the core of the permanent magnet motor includes left and right sides, after cutting the left side of the core, when the right side of the core needs to be cut, the staff needs to manually remove the core from the clamp, adjust the direction, and then re-lock it, which takes a lot of time.

[0027] According to this specific embodiment, the base 101 is used to support the locking assembly 102 .

[0028] Among them, the rotating shaft 103 is rotatably connected to the base 101 and is located on the side of the base 101; the worm wheel 104 is fixedly connected to the rotating shaft 103 and is located on the side of the rotating shaft 103; the worm 105 is rotatably connected to the base 101 and meshes with the worm wheel 104; the motor 106 is fixedly connected to the base 101, and the output end of the motor 106 is fixedly connected to the worm 105 and is located on the side of the base 101; the placement table 107 is fixedly connected to the rotating shaft 103 and is located on the top of the rotating shaft 103; the two locking parts 108 are mirror-arranged on both sides of the placement table 107. When in use, the base 101 is installed next to the core cutting device, and the staff places the core of the permanent magnet motor 106 on the placement table 107, and locks and fixes the core through the two locking parts 108, and then cuts the left side of the core through the cutting device. After the left side of the core is cut, the motor 106 is started to drive the worm 105 to rotate, and the worm 105 drives the worm wheel 104 to rotate. The worm wheel 104 drives the placement table 107 to rotate via the rotating shaft 103, thereby driving the core to rotate, so that the right side of the core rotates to the side of the cutting device; the present application can quickly adjust the position of the core so as to cut the left and right sides of the core.

[0029] Secondly, the cylinder 109 is fixedly connected to the placement platform 107 and is located at the bottom of the placement platform 107; the connecting rod 110 is fixedly connected to the output rod of the cylinder 109 and is located at the side of the cylinder 109; the connecting piece 111 is arranged at the side of the connecting rod 110; and the profiling clip 112 is arranged at the side of the connecting piece 111. The profiling clip 112 is adapted to the shape of the iron core, and the iron core of the permanent magnet motor 106 is placed on the placement platform 107. The connecting rod 110 is driven to move by the cylinder 109, and the connecting rod 110 drives the connecting piece 111 and the profiling clip 112 to approach the iron core. The iron core is locked and fixed by the two profiling clips 112 to prevent movement when the iron core is cut.

[0030] At the same time, the guide rail 113 is fixedly connected to the connecting rod 110 and is located on the side of the connecting rod 110; the bidirectional threaded screw 114 is rotatably connected to the guide rail 113 and is located on the side of the guide rail 113; the two sliders 115 are respectively slidably connected to the guide rail 113, and are respectively threadedly connected to the bidirectional threaded screw 114, and are located at both ends of the bidirectional threaded screw 114; the two insertion rods 116 are respectively fixedly connected to the two sliders 115, and are respectively located on the sides of the two sliders 115; the contour clip 112 has two slots 118, and the two slots 118 are located on both sides of the contour clip 112. When it is necessary to cut iron cores of different types, there may be a situation where the profiling clip 112 cannot adapt to the outer shape of the iron core. At this time, the staff reverses the bidirectional threaded screw 114. Both ends of the bidirectional threaded screw 114 have threads in the thread direction, and the two sliders 115 are located at the two ends of the bidirectional threaded screw 114 with opposite thread directions. The bidirectional threaded screw 114 is reversed so that the two sliders 115 slide in directions away from each other until the insertion rod 116 is moved out of the slot 118. Then the profiling clip 112 that is adapted to the outer shape of the iron core can be replaced, and the replaced profiling clip 112 is placed between the two insertion rods 116. The staff rotates the bidirectional threaded screw 114 forward to insert the insertion rod 116 into the slot 118 on the profiling clip 112, thereby completing the fixation of the profiling clip 112; through this fixing method, it is easy to replace the profiling clip 112, so that different types of iron cores can be locked.

The connecting rod 110 drives the connecting piece 111 and the contour clamp 112 to approach the core, and the core is locked and fastened by the two contour clamps 112. Then, the left side of the core is cut by the cutting device. After the left side of the core is cut, the motor 106 is started to drive the worm 105 to rotate, and the worm 105 drives the worm wheel 104 to rotate. The worm wheel 104 drives the placement table 107 to rotate via the rotating shaft 103, thereby driving the core to rotate, so that the right side of the core rotates to the side of the cutting device; the present application can quickly adjust the position of the core so as to cut the left and right sides of the core. When it is necessary to cut iron cores of different types, there may be a situation where the profiling clip 112 cannot adapt to the outer shape of the iron core. At this time, the staff reverses the bidirectional threaded screw 114. Both ends of the bidirectional threaded screw 114 have threads in the thread direction, and the two sliders 115 are located at the two ends of the bidirectional threaded screw 114 with opposite thread directions. The bidirectional threaded screw 114 is reversed so that the two sliders 115 slide in directions away from each other until the insertion rod 116 is moved out of the slot 118. Then the profiling clip 112 that is adapted to the outer shape of the iron core can be replaced, and the replaced profiling clip 112 is placed between the two insertion rods 116.
