One end of the first drive screw 23 is fixedly connected to a knob 26 that fits against the outer wall of the frame 1;

[0028] The first sliding seat 21, the arc-shaped limiting arm 22 and the connecting driving arm 25 are provided in two groups and are symmetrically arranged on opposite sides of the first driving screw 23. During the rotation process, the first driving screw 23 can drive the two first sliding seats 21 to move closer to or away from each other through the two connecting driving arms 25.

[0029] When the core positioning mechanism 2 operates on the core body 5, in order to improve the verticality of the core body 5 during stacking and prevent the core body 5 from being offset during stacking, thereby affecting the stacking effect of the core body 5, the knob 26 can be rotated to drive the threaded slide 24 to slide along the inner wall of the first directional slide groove 12 through the rotation of the first drive screw 23. The sliding of the threaded slide 24 drives the first sliding seat 21 to slide along the inner wall of the through-slide groove 11 through the connection of the connecting drive arm 25. The sliding of the first sliding seat 21 drives the arc-shaped limiting arm 22 to clamp and protect the core body 5, thereby improving the stacking flatness of the core body 5 when the core body 5 is stacked.

[0030] Furthermore, the threaded slide 24 forms a sliding structure between the first drive screw 23 and the first directional slide groove 12, which is conducive to the rotation of the first drive screw 23, driving the threaded slide 24 to slide along the inner wall of the first directional slide groove 12, thereby realizing the control operation of the rotation of the connecting drive arm 25.

[0031] Furthermore, the connecting drive arm 25 forms a rotating structure between the screw-connected slide 24 and the first sliding seat 21, which is conducive to the sliding of the screw-connected slide 24 through the connection of the first sliding seat 21, driving the connecting drive arm 25 to rotate, thereby realizing the control operation of the sliding of the first sliding seat 21.

[0032] Furthermore, the first sliding seat 21 forms a sliding structure by connecting the driving arm 25 and the through-slide groove 11. Two groups of first sliding seats 21 are provided. The position distribution of the two groups of first sliding seats 21 is symmetrical about the central axis of the frame 1, which is conducive to the rotation of the connecting driving arm 25, driving the first sliding seat 21 to slide along the inner wall of the through-slide groove 11, thereby achieving the effect of effective sliding of the arc-shaped limiting arm 22.

[0033] Furthermore, the arc-shaped limit arms 22 form a protective structure between the first sliding seat 21 and the core body 5, and the outer wall contours of the two groups of arc-shaped limit arms 22 are semicircular, which is conducive to the sliding of the first sliding seat 21, driving the arc-shaped limit arms 22 to clamp and protect the core body 5, thereby achieving the effect of improving the stacking flatness of the core body 5 when the core body 5 is stacked.

[0034] Example 2: Figure 1 、 Figure 4 and Figure 5As shown, the present invention proposes a stator core processing device, wherein the core pressing mechanism 3 includes a pressing component 31 for pressing the core body 5, and a second sliding seat 32 slidably connected to the frame 1 and used to set the pressing component 31, and a driving plate 33 fixedly connected to the second sliding seat 32, and a second driving screw 34 rotatably connected to the frame 1, and a screw-connecting slide 35 slidably connected to the frame 1 and screwed to the second driving screw 34, and a rolling wheel 36 rotatably connected to the screw-connecting slide 35 and movably connected to the driving plate 33. The frame 1 is further provided with a driving motor 37 for driving the second driving screw 34, and a guide groove 331 for the rotation of the rolling wheel 36 is provided on the driving plate 33. The frame 1 is provided with a second directional slide 13 for the directional reciprocating sliding of the second sliding seat 32, and a third directional slide 14 for the directional reciprocating sliding of the screw-connected slide 35. The length directions of the second directional slide 13 and the third directional slide 14 are perpendicularly arranged, and the length direction of the guide groove 331 is inclined to the length directions of the second directional slide 13 and the third directional slide 14.

[0035] The pressing component 31 , the second sliding seat 32 and the driving plate 33 are provided in two groups and are symmetrically arranged on opposite sides of the second driving screw 34 . The second driving screw 34 can drive the two second sliding seats 32 to move closer to or away from each other through the two driving plates 33 during rotation.

[0036] When using the iron core pressing mechanism 3, it is necessary to first clamp and limit the iron core body 5 through the iron core positioning mechanism 2. In order to make the pressing component 31 adapt to the iron core bodies 5 of different sizes, the driving motor 37 can be turned on according to the size of the iron core body 5. Through the rotation of the second driving screw 34, the threaded slide 35 is driven to slide along the inner wall of the third directional slide groove 14. At the same time, the sliding of the threaded slide 35 drives the rolling wheel 36 to slide along the inner wall of the guide groove 331, and drives the second sliding seat 32 fixedly connected to the driving plate 33 to slide along the inner wall of the second directional slide groove 13, thereby driving the two sets of lifting drives 311 to slide relative to each other along the inner wall of the sliding guide rail 312, so as to improve the adjustable control operation applicable to the iron core bodies 5 of different sizes when the iron core pressing mechanism 3 is used to press the iron core body 5.

[0037] Finally, when the core body 5 is processed by the core pressing mechanism 3, in order to improve the positioning effect of the core bodies 5 at different heights, the lifting drive 311 can be turned on to drive the lifting mounting seat 313 to slide along the inner wall of the lifting slide 15. The movement of the lifting mounting seat 313 drives the pressing ring 314 to press the core body 5, thereby achieving the pressing effect of the core bodies 5 at different heights.

[0038] Furthermore, the threaded slide 35 forms a sliding structure between the second drive screw 34 and the third directional slide groove 14, which is conducive to the rotation of the second drive screw 34, driving the threaded slide 35 to slide along the inner wall of the third directional slide groove 14, thereby realizing the control operation of the sliding of the rolling wheel 36.

[0039] Furthermore, the rolling wheel 36 forms a sliding structure between the screw-connected slide 35 and the guide groove 331. The two guide grooves 331 on the two driving plates 33 are cross-arranged, which is conducive to the sliding of the screw-connected slide 35, driving the rolling wheel 36 to slide along the inner wall of the guide groove 331, thereby realizing the control operation of the relative sliding of the two groups of second sliding seats 32.

[0040] Furthermore, the second sliding seat 32 forms a sliding structure between the driving plate 33 and the second directional sliding groove 13, which is beneficial to the connection of the driving plate 33, driving the second sliding seat 32 to slide along the inner wall of the second directional sliding groove 13, thereby improving the control operation of the positioning and adjustment of the core bodies 5 of different sizes when processing and producing the core bodies 5.

[0041] Example 3: Figure 1 、 Figure 4 and Figure 5 As shown, a stator core processing device proposed in the present invention, compared with Example 2, as another embodiment of the present invention, the pressing component 31 includes a lifting driver 311 fixed on the second sliding seat 32, and a sliding guide rail 312 fixedly set on the frame 1 and used for the lifting driver 311 to be slidably connected, and a lifting mounting seat 313 set at the movable end of the lifting driver 311, and a pressure ring 314 set on the lifting mounting seat 313 and adapted to the lower core body 5. The lifting mounting seat 313 is longitudinally slidably connected to the frame 1, and a lifting slide groove 15 for the lifting mounting seat 313 to be slidably connected is provided on the frame 1, and the pressure ring 314 is arranged in a semicircular ring structure.

[0042] By setting the pressure ring 314, it is beneficial to perform pressurization operation on the core body 5. In order to improve the operation effect on the core bodies 5 at different heights, the lifting driver 311 can be turned on to drive the lifting mounting seat 313 to slide along the inner wall of the lifting slide 15. The movement of the lifting mounting seat 313 drives the pressure ring 314 to apply pressure to the core body 5, thereby playing the role of pressurizing the core bodies 5 at different heights.

[0043] Furthermore, the lifting drive 311 forms an adjustment structure between the second sliding seat 32, the second directional slide groove 13 and the sliding guide rail 312. There are two groups of lifting drives 311. The position distribution of the two groups of lifting drives 311 is symmetrical about the central axis of the frame 1, which is conducive to the second sliding seat 32 sliding along the inner wall of the second directional slide groove 13, driving the lifting drive 311 to slide along the inner wall of the sliding guide rail 312, thereby effectively adjusting the distance between the two groups of pressure rings 314.

[0044] Furthermore, the lifting mounting seat 313 forms a lifting structure through the lifting driver 311 and the lifting slide 15. There are two groups of lifting mounting seats 313. The position distribution of the two groups of lifting mounting seats 313 is symmetrical about the central axis of the iron core body 5, which is conducive to the driving of the lifting driver 311 to drive the lifting mounting seat 313 to slide along the inner wall of the lifting slide 15, thereby achieving the effect of adjusting the height of the pressure ring 314.

[0045] Example 4: Figure 2 As shown, a stator core processing device proposed by the present invention, compared with Example 1, as another embodiment of the present invention, the upper end of the first sliding seat 21 is telescopically connected with an adjusting protective block 27, and the adjusting protective block 27 is also provided with an arc-shaped limiting arm 22 that can interfere with the core body 5, and the first sliding seat 21 is provided with a telescopic connection groove 211 for the longitudinal telescopic sliding connection of the adjusting protective block 27, and the first sliding seat 21 is provided with a limiting clamping rod 28 for limiting the adjusting protective block 27, and the adjusting protective block 27 is provided with a limiting clamping hole 271 for inserting the limiting clamping rod 28, and there are multiple limiting clamping holes 271, and each limiting clamping hole 271 is arranged along the sliding direction of the adjusting protective block 27 on the first sliding seat 21, and the first sliding seat 21 is provided with an elastic member 29 that can keep the limiting clamping rod 28 always inserted in the limiting clamping hole 271.

[0046] During operation, by setting the adjustable protection block 27, it is beneficial to improve the adjustability of the protection of the core body 5 when the core bodies 5 of different heights are stacked. According to the needs of the protection height, the limit card rod 28 can be pulled. Under the connection of the elastic member 29, the limit card rod 28 slides from the inner wall of the limit card hole 271, and the adjustment protection block 27 is pulled. When it is pulled to the required protection height, the limit card rod 28 is loosened. Under the reaction of the elastic member 29, the limit card rod 28 is engaged and fixed to the protection block, thereby improving the effect of adjusting the protection at different heights when the core body 5 is stacked.

[0047] Example 5: Figure 1 and Figure 6As shown, a stator core processing device is shown, wherein the frame 1 is further provided with a core limiting mechanism 4 located in the inner ring of the core body 5, and the core limiting mechanism 4 includes a fixed column 41 fixed to the frame 1, and a driving slip ring 42 axially slidingly connected to the fixed column 41, and an electric push rod 43 provided on the fixed column 41 and used to drive the driving slip ring 42 to slide axially back and forth on the fixed column 41, and a telescopic rod 44 provided on the fixed column 41, and a limiting column 45 provided at the movable end of the telescopic rod 44 and capable of abutting against the inner ring wall of the core body 5, and a movable end rotatably connected to the telescopic rod 44. The rotating rod 46 between the driving slip ring 42 and the fixed column 41 is vertically located at the center of the iron core body 5, the length direction of the telescopic rod 44 is cross-set with the length direction of the fixed column 41, the length direction of the limit column 45 is consistent with the length direction of the fixed column 41, the telescopic rod 44 and the limit column 45 and the rotating rod 46 are provided in multiple groups and are arranged in a circular array structure with the fixed column 41 as the center. In the process of the electric push rod 43 driving the driving slip ring 42 to slide on the fixed column 41, the limit column 45 on the telescopic rod 44 can be driven to gradually approach or move away from the iron core body 5 through the rotating rod 46.

[0048] When using the core limiting mechanism 4, in order to improve the positioning effect of the core body 5 with different inner diameters and the degree of fit with the inner wall of the core body 5, the electric push rod 43 can be opened according to the inner diameter size of the core body 5 to drive the driving slip ring 42 to slide along the outer wall of the fixed column 41. The sliding of the driving slip ring 42 drives the limiting column 45 fixedly connected to the telescopic rod 44 to perform telescopic movement through the rotation of the rotating rod 46, thereby achieving the effect of abutting against the inner wall of the core body 5. Therefore, the lamination flatness of the core body 5 can be further improved by cooperating with the core positioning mechanism 2.

[0049] Furthermore, the driving slip ring 42 forms a lifting structure between the electric push rod 43 and the fixed column 41, which is conducive to the driving of the electric push rod 43 to drive the driving slip ring 42 to slide along the outer wall of the fixed column 41, thereby realizing the control operation of the rotation of the rotating rod 46.

[0050] Furthermore, the rotating rod 46 forms a rotating structure between the driving slip ring 42 and the telescopic rod 44. The rotating rod 46 is arranged in a ring shape on the outer wall of the fixed column 41, which is conducive to driving the sliding of the slip ring 42 through the connection of the telescopic rod 44, driving the rotating rod 46 to rotate, thereby realizing the control operation of the telescopic movement of the limit column 45.

[0051] Furthermore, the movable end of the telescopic rod 44 is fixedly connected to a mounting bracket (not shown) for mounting the limiting post 45. The mounting bracket is arranged in a U-shaped structure, and the ends of the limiting post 45 are rotatably connected to the two ends of the opening of the mounting bracket. This allows the limiting post 45 to be rotatably connected to the movable end of the telescopic rod 44 via the mounting bracket, thereby improving the contact between the limiting post 45 and the inner wall of the core body 5, thereby further improving the positioning effect of the core limiting mechanism 4 on the core body 5.
