DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] The motor 7 (model YS7134) mentioned in the utility model can be purchased from the market or obtained by private customization.

[0021] See also Figures 1 to 4 The utility model provides an embodiment: a magnetic core layering blanking combined clamp, including a base 1, a motor 7 is installed on the inner side of the base 1 through a motor cavity 6, a short shaft 8 is fixedly connected to the output end of the motor 7, and a rotating shaft 4 is fixedly connected to the upper end face of the short shaft 8. Four rotating layering mechanisms 5 are arranged on the outer surface of the rotating shaft 4, and a shielding mechanism 2 is arranged on the upper end face of the base 1. The shielding mechanism 2 includes an annular plate A201, and a through groove A202 is arranged on one side of the outer surface of the annular plate A201. Three conveying mechanisms 3 are arranged above the shielding mechanism 2. The conveying mechanism 3 includes a bottom plate 305, an annular plate B301 is fixedly installed on the outer side of the upper end face of the bottom plate 305, a circular groove 303 is arranged in the middle of the upper end face of the bottom plate 305, and a through groove B304 is arranged through one side of the annular plate B301 and the bottom plate 305.

[0022] Furthermore, an annular clamping plate is installed on the lower end surface of the annular plate A201, and an annular clamping groove is provided on the upper end surface of the base 1. The annular clamping plate is matched with the annular clamping groove, so that the annular plate A201 can be removed from the base 1.

[0023] A through hole 302 is provided on one side of the circular groove 303 . The diameter of the magnetic core is smaller than the aperture of the through hole 302 . The thickness of the bottom plate 305 is consistent with the thickness of the brushed zirconium powder used as isolation. The magnetic core to be layered can be placed inside the through hole 302 .

[0024] The rotating layering mechanism 5 includes a fixed ring 501, which is fixedly connected to the outer surface of the rotating shaft 4. An arc plate 502 is fixedly installed on one side of the outer surface of the fixed ring 501. The outer surface of the arc plate 502 is covered with a rubber pad. When the rotating shaft 4 rotates, the fixed ring 501 and the arc plate 502 can be driven to rotate, so that the arc plate 502 can separate the magnetic cores.

[0025] The annular plate A201 and the bottom annular plate B301, as well as every two annular plates B301, are movably connected via a locking mechanism. The locking mechanism includes a positioning hole and a positioning rod. The positioning rod is matched with the positioning hole.
