The structure is characterized in that the iron core stack is driven to move by taking the wheel rotating disc and the rotating power mechanism as an automatic wheel rotating mechanism. Meanwhile, the stacking tray is used as a main mechanism for fixing the iron core stack, and a plurality of stacking frames on the stacking tray can be mutually converted in a working state and a non-working state, so that the feeding efficiency is improved.

The iron core positioning column is arranged on the outer side wall of the wheel turntable, and the upper end of the iron core positioning column is higher than the upper bottom surface of the wheel turntable; the connecting position of the lower hanging column and the stacking tray is close to the stacking rack. The four-station feeding device has the advantages that the efficiency and the cost can be well balanced through the quadrilateral structure, and the purpose of four-station feeding is achieved. And each side is provided with two stack-holding frames, so that the state that two stacks of iron cores are loaded simultaneously can be achieved, and iron core materials obtained by the two stacks of iron cores can be alternately stacked through transformation in the subsequent processing process, so that the efficiency is improved, and the thickness influence caused by material tolerance can be reduced. And the position of the lower hanging column is arranged at the position which is as close to the stack frame as possible, so that the bearing stability of the whole structure can be effectively improved.

In a further scheme, a guide inclined plane is arranged at the position, corresponding to the stacking rack, of the edge of the bottom surface of the wheel rotating disc. The situation that the iron core sheet is clamped at the position of the wheel turntable and cannot fall down due to random inclination of the iron core sheet sleeve on the iron core positioning column can be avoided through the arrangement of the guide inclined plane.

Compared with the prior art, the utility model discloses an iron core material loading carousel provides good stability through the upper and lower suspension type structure of wheel carousel and flourishing buttress dish. Utilize the cooperation of holding the buttress frame and iron core reference column to fix the iron core buttress simultaneously to realize the rotation of a plurality of stations. It should be noted that the iron core positioning column is not only used for positioning the iron core stack, but also can be used as a rail for lifting the iron core stack in a subsequent process, so as to be directly matched with subsequent automatic equipment. In conclusion, the iron core feeding turntable has the characteristics of stable structure, high rotation efficiency and capability of being effectively matched with subsequent mechanical automatic operation.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1.

As shown in fig. 1-3, this embodiment describes an iron core loading turntable, which includes a loading base a1 and a wheel turntable a2, the loading base a1 is connected to the center of the wheel turntable a2 through a rotary power device A3, lower hanging columns A4 are uniformly distributed on the circumference of the lower bottom surface of the wheel turntable a2, a holding tray A5 is fixedly connected to the lower end of the lower hanging column A4, the holding tray A5 is a regular polygon, an abdicating hole A6 avoiding interference with the rotary power device A3 is arranged at the center of the regular polygon, the outer side wall of the holding tray A5 and the outer side wall of the wheel turntable a2 are on the same plane, a holding tray A7 extending outwards and horizontally is arranged on the outer side wall of the holding tray A5, the width of the holding tray A7 is smaller than the maximum outer diameter of an iron core, an iron core positioning column A7 is provided with an iron core positioning column A8, the maximum outer diameter of the iron core positioning column A8 is matched with the inner hole of the iron core, and the iron core A8 is in a truncated cone-shaped structure, and the distance from the center of the iron core positioning column A8 to the outer side wall of the wheel turntable A2 is equal to the maximum radius of the iron core.

The iron core positioning column A8 is arranged on the outer side wall of the wheel turntable A2, the iron core positioning column A5 is a square, two stacking racks A7 are arranged on each outer side wall, and the upper end of the iron core positioning column A8 is higher than the upper bottom surface of the wheel turntable A2; the connecting position of the lower hanging column A4 and the tray A5 is close to the stacking rack A7. As shown in fig. 4, a guide inclined plane a9 is arranged on the position of the edge of the upper bottom surface of the wheel rotating disc a2 corresponding to the position of the palletizing frame a 7.

When the iron core stacking machine works, the inner holes of the iron core stacks are sleeved into the two iron core positioning columns A8 on one side of the stacking plate A5 through manual or other means, then the wheel rotating plate A2 drives the wheel to rotate, and the side containing the iron core stacks enters a production station. Meanwhile, other empty stacking racks A7 are continuously discharged. When the iron core plate is inclined to one side of the wheel turntable A2 due to inclination during discharging, the edge of the iron core plate contacts the guide inclined plane A9, so that the iron core plate returns to the normal state and continues to fall. During subsequent mechanical operation, the lifting machines are directly inserted into two sides of the stacking frame A7, the width difference between the stacking frame A7 and the iron core sheets is utilized to directly lift the whole stack of iron core sheets, and feeding is conducted through the guide of the iron core positioning column A8.
