[0041] Furthermore, in order to be able to stack multiple groups of stator punching bodies 5, specifically, the stacking assembly 4 includes a cylinder 41, the cylinder 41 is fixedly connected to the upper side of the top plate 3, and a mounting plate 42 is fixedly connected to the output end of the cylinder 41. The mounting plate 42 is penetrated by the support column 2 and is slidably connected to the support column 2. An elastic telescopic head 44 and a hollow pressure block 43 are fixedly connected to the lower side of the mounting plate 42. By starting the cylinder 41, the output end of the cylinder 41 drives the mounting plate 42 to descend, causing the elastic telescopic head 44 and the hollow pressure block 43 to descend. When the hollow pressure block 43 squeezes the stator punching body 5, the stacking of multiple groups of stator punching bodies 5 is achieved.

[0042] In the embodiment of the present invention, in order to ensure that the multiple groups of stator punching bodies 5 are in a stable state during the lamination process, specifically, the limiting mechanism 7 includes a moving block 71, the moving block 71 is penetrated by a guide rod 72 and is slidably connected to the guide rod 72, the guide rod 72 is fixedly connected to the operating table of the machine body 1, the top of the moving block 71 is slidably connected to a push rod 73, and the end of the push rod 73 away from the moving block 71 is fixedly connected to a clamping block 74, and a groove 75 is provided on the lower side of the push rod 73.

The lower side of the slide plate 783 is fixedly connected to the limit rod 784, which penetrates the fixing plate 785 and is slidably connected to the fixing plate 785. Through the descent of the elastic expansion head 44 and the hollow pressure block 43, when the elastic expansion head 44 presses the sleeve 652 downward, the positioning arc plate 65 and the disc 61 are lowered, thereby driving the steel rope 77 to move, so that the moving block 71 moves, and the push rod 73 and the clamping block 74 move, so that the clamping block 74 is pressed against The stator punching body 5 is positioned. In the process of the elastic telescopic head 44 driving the socket 652 to continue to press down, the moving block 71 slides in the groove 75, compressing the connecting spring, and the extrusion rod 781 moves toward the fixed column 76. The extrusion rod 781 is squeezed by the fixed column 76, the hinge rod 782 moves, and the slide plate 783 drives the limit rod 784 to be close to the operating table of the body 1 to fix the moving block 71. At this time, when the elastic telescopic head 44 continues to squeeze the socket 652, the elastic telescopic head 44 will shrink, which is convenient for stacking stator punching bodies 5 with different diameters.

[0043] Further, in order to protect the staff during the device process, specifically, the protection mechanism 8 includes a protection plate 81, the protection plate 81 is hinged on the outer wall of the bracket 82, the bracket 82 is fixedly connected to the upper side of the body 1, a straight rod 83 is hinged on the outer wall of the protection plate 81, the end of the straight rod 83 away from the protection plate 81 is hinged to a guide block 84, the side of the guide block 84 away from the straight rod 83 is hinged to an inclined rod 85, the end of the inclined rod 85 away from the guide block 84 is hinged to a vertical rod 86, the top of the vertical rod 86 is fixedly connected to the vertical rod 86.

[0044] Furthermore, when the output end of the cylinder 41 drives the mounting plate 42 to rise and reset, it drives the vertical rod 86 to rise and reset, so that the inclined rod 85 drives the guide block 84 to move, and then under the action of the straight rod 83, the protective plate 81 rotates downward, making it easier for subsequent staff to place the stator punching body 5.

[0045] It should be noted that the above-mentioned electrical components are all existing technology products. Technical personnel in this field select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all universal standard parts or components known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. The applicant does not make specific restrictions here.

[0046] When in use, firstly, the stator punch body 5 is passed through multiple groups of positioning arc plates 65 and placed on the operating table of the machine body 1, and then the motor 63 is started, and the output shaft of the motor 63 rotates, driving the rotating ring 642 to rotate, and then driving the arc rod 641 to move, so that the sliding block 64 slides in the slide groove 62, driving the positioning arc plate 65 to move, and then the stator punch body 5 is positioned, and the inner wall of the stator punch body 5 can be tightly attached to the positioning arc plate 65, so that multiple groups of stator punch bodies 5 are stacked stably, and their centers are on the same vertical line, and then the cylinder 41 is started, and the output end of the cylinder 41 drives the mounting plate 42 to descend, so that the elastic telescopic head 44 and the hollow pressure block 43 descend, and the stator punch body 5 is squeezed in the hollow pressure block 43, so that the multiple groups of stator punch bodies 5 are stacked;

[0047] At the same time, during this process, the elastic expansion head 44 descends to press the sleeve 652 downward, causing the positioning arc plate 65 and the disc 61 to descend, thereby driving the steel rope 77 to move, causing the moving block 71 to move, driving the push rod 73 and the clamping block 74 to move, so that the clamping block 74 positions the stator punch body 5. In the process of the elastic expansion head 44 driving the sleeve 652 to continue to press downward, the moving block 71 slides in the groove 75, compressing the connecting spring, and the extrusion rod 781 moves toward the fixed column 76. The extrusion rod 781 is squeezed by the fixed column 76, the hinged rod 782 moves, and the slide plate 783 drives the limiting rod 784 to be close to the operating table of the body 1 to fix the moving block 71.

When the output end of the cylinder 41 drives the mounting plate 42 to rise and reset, the vertical rod 86 is driven to rise and reset, so that the inclined rod 85 drives the guide block 84 to move, and then under the action of the straight rod 83, the protective plate 81 is rotated downward, so that the subsequent staff can take out the stator punching body 5.
