The workbench 3 is provided with through holes 31 corresponding to the lifting rods 6 for the upper ends thereof to pass through.

[0039] The tire core 7 is a columnar structure and is vertically arranged at the center of the upper end surface of the workbench 3. The cross-sectional profile of the tire core 7 is adapted to the inner peripheral profile of the stator core 10 to be processed. An annular sink groove 71 is provided on the upper peripheral side of the tire core 7.

The lower end surface of the movable bottom plate 8 is used to contact and cooperate with the lifting rod 6. The lifting rod 6 lifts the movable bottom plate 8 to rise and fall relative to the tire core 7.

[0041] The constraint plate 9 is a circular ring structure formed by splicing a pair of semicircular ring-shaped constraint sub-plates 91. The constraint plate 9 is used to be detachably connected to the annular groove 71 at the upper end of the tire core 7, and the inner diameter of the constraint plate 9 is adapted to the outer diameter of the annular groove 71 provided at the upper end of the tire core 7. A pressing area for accommodating the stator core 10 to be processed is formed between the lower end surface of the constraint plate 9 and the upper end surface of the movable bottom plate 8.

[0042] Among them, in order to facilitate the assembly and fixation of the tire core 7, a tire jig base plate 72 is also provided between the tire core 7 and the workbench 3, and the tire jig base plate 72 is provided with a guide hole 721 corresponding to the lifting rod 6 for the lifting rod 6 to pass through the tire jig base plate 72; as a preferred optional implementation mode, the edge of the tire jig base plate 72 is provided with a first locking bolt 722 that passes through the tire jig base plate 72 and threadedly locks the tire jig base plate 72 on the workbench 3, and the workbench 3 is provided with a first thread groove 33 corresponding to the first locking bolt 722 for cooperating with the first locking bolt 722; the center of the lower end surface of the tire jig base plate 72 is provided with a second locking bolt 723 that passes through the tire jig base plate 72 and threadedly locks the tire jig base plate 72 and fixes the lower end of the tire core 7, and the bottom of the tire core 7 is provided with a second thread groove 73 that cooperates with the second locking bolt 723; the first thread groove 33 and the second thread groove 73 are both threaded countersunk grooves.

[0043] In addition, in order to facilitate the assembly of the base 1 and the workbench, the bottom of the base 1 corresponds to the support rod 2 and is provided with a third locking bolt 11 which is threaded through the base 1 and locks and fixes the lower end of the support rod 2 to the upper end surface of the base 1, and the lower end of the support rod 2 is correspondingly provided with a third threaded groove 21 which cooperates with the third locking bolt 11; the upper end surface of the workbench 3 corresponds to the support rod 2 and is provided with a fourth locking bolt 32 which is threaded through the workbench 3 and locks and fixes the upper end of the support rod 2 to the lower end surface of the workbench 3, and the upper end of the support rod 2 is correspondingly provided with a fourth threaded groove 22 which cooperates with the fourth locking bolt 32.

[0044] Since the movable plate 5 is driven to rise and fall by the lifting drive unit 4, and the movable plate 5 is the key to driving the lifting rod 6 to rise and fall, in order to improve the connection reliability, the lower end surface of the movable plate 5 is provided with a fifth locking bolt 52 corresponding to the lifting rod 6, which passes through the movable plate 5 through a thread and locks the lower end of the lifting rod 6 to the upper end surface of the movable plate 5; the lower end of the lifting rod 6 is correspondingly provided with a fifth threaded groove 61 that cooperates with the fifth locking bolt 52; the movable plate 5 is fixedly connected to the lifting drive end 41 of the lifting drive unit 4 through the sixth locking bolt 51.

[0045] Focus on reference Figures 1 to 3 When the device of the present embodiment is in use, it is only necessary to first sleeve and overlap the motor core 10 to be press-fitted from the tire core 7 and place it on the upper end surface of the movable bottom plate 8. When it is overlapped to a preset height, a pair of constraint sub-plates 91 of the constraint plate 9 are clamped and installed. Then, the lifting drive unit 4 is started, and the lifting drive end 41 of the lifting drive unit 4 drives the movable plate 5 to drive the lifting rod 6 to rise, so that the movable bottom plate 8 is connected to the motor core 10 stacked on the upper end surface of the movable bottom plate 8 and is lifted until it is against the constraint plate 10 and press-fitted. After the press-fitting reaches the preset requirement, it is only necessary to pause the lifting of the lifting drive unit 4, then remove the constraint plate 8, and then restart the lifting drive unit 4, so that the lifting drive end of the lifting drive unit 4 further lifts the motor core 10 that has been press-fitted, so that the press-fitted motor core 10 is gradually removed from the tire core 7 upward to realize tire withdrawal.

[0046] The device of this scheme can not only realize the compression assembly of the stator core, but also realize the stripping process of the stator core, so that the two processes that require two workstations and tooling to be realized in the traditional scheme are concentrated on one device, which improves production efficiency, facilitates operation and reduces management costs.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
