However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0018] Example 1

[0019] See Figures 1 to 6 As shown, the segmented stator core loading device involved in this embodiment includes a working platform 1 with a working hole (unmarked), a core clamping seat 2 in the working hole 1, a first linear reciprocating motion mechanism 100 for controlling vertical up and down movement at the bottom of the core clamping seat 2, a pressure block 3 above the core clamping seat 2, a second linear reciprocating motion mechanism 200 for controlling vertical up and down movement at the top of the pressure block 3, and a core clamping mechanism 300 below the working platform 1; it also includes a cage 4, which has a core placement channel 5 that runs vertically through the structure.

[0020] Furthermore, the iron core clamping mechanism 300 includes a clamping fixing plate 6 arranged coaxially with the working hole. A clamping movable plate 7 is rotatably connected to the top of the clamping fixing plate 6. The clamping fixing plate 6 is circumferentially distributed with a plurality of linear grooves 8 extending radially along the working hole and with adjacent intervals at equal angles. A linear slider 9 is slidably connected in the linear grooves 8. A chuck 10 is provided at one end of the linear slider 9 facing the axis of the working hole. A guide wheel 11 is rotatably connected to the top of the linear slider 9. The clamping movable plate 7 is circumferentially distributed with guide holes 12 corresponding to the linear grooves and extending tangentially along the working hole. Each guide wheel 11 is slidably connected in a guide hole 12. A radially extending arm 13 is provided on the side of the clamping movable plate 7. The iron core clamping mechanism 300 also includes a first electric push rod 14. The telescopic rod end of the first electric push rod 14 is hinged to the arm 13.

[0021] Furthermore, the first linear reciprocating motion mechanism 100 includes a mounting frame 15 fixed to the working platform 1. A lead screw nut 16 coaxially arranged with the working hole is fixedly connected to the mounting frame 15. A lead screw 17 is threadedly connected to the lead screw nut 16. The iron core clamping seat 2 is located at one end of the lead screw 17. The other end of the lead screw 17 is connected to a motor 18 for controlling rotation.

[0022] Furthermore, the second linear reciprocating motion mechanism 200 includes a pneumatic push rod 19, and the pressure block 3 is disposed at the telescopic end of the pneumatic push rod 19.

[0023] In this embodiment, firstly, the core clamping seat 2 extends out of the working hole 1 and is located above the upper end face of the working platform 1. At this time, the completed round core is taken out and positioned and clamped on the core clamping seat 2. The downward-moving pressure block 3 presses the core tightly onto the core clamping seat 2. Then, the first linear reciprocating motion mechanism 100 and the second linear reciprocating motion mechanism 200 simultaneously move the core clamping seat 2, which holds the core, downward until the core is inserted into the core clamping seat. Inside the mechanism 300, the pressure block 3 moves upward and resets, the iron core clamping mechanism 300 operates, and the iron core is circumferentially clamped. After the cage 4 is taken out, it is placed on the working platform 1 and set coaxially with the working hole 1. Finally, the pressure block 3 moves downward and presses against the iron core. Then the pressure block 3 and the iron core clamping seat 2 move upward synchronously. At the same time as moving upward, the iron core clamping mechanism 300 is released. After the iron core is inserted into the cage 4, the pressure block 3 and the iron core clamping seat 2 reset, thus completing the automatic cage insertion operation of the iron core.

[0024] The segmented stator core loading device involved in this utility model uses two sets of upper and lower linear reciprocating motion mechanisms to control the axial position adjustment of the core. When the cage is not removed, the core can be moved to the center position of the core clamping mechanism, which clamps it. After the cage is removed, the core clamping mechanism is released. At the same time as the release, the upper and lower linear reciprocating motion mechanisms control the core to move axially until it is inserted into the cage, thus achieving automatic loading. It has a high degree of automation, uniform assembly standards, complete overall functions, and strong practicality.
