Products with different specifications can be positioned and connected quickly and conveniently by replacing different shaft sleeves 1321.

When the winding machine of the invention works, firstly, a product is placed on the shaft sleeve 1321, the lifting frame 131 descends, the pressing plate 133 is pressed and fixed on the product 17, the driving piece 121 starts to work and drives the movable seat 12 to move, and the first extrusion guide block 182 or the second extrusion guide block 183 is in extrusion contact with the product 17. The enameled wire at this time is threaded on the winding rod 142, and simultaneously the end of the enameled wire is clamped by the wire cutting and clamping mechanism 16, the driving part 181 drives and controls the feeding position of the shell block, then the motor 141 can start the work to control the winding rod 142 to rotate, and the enameled wire is wound on the product 17 after being guided by the wire guiding mechanism. When one tooth on the product 17 is wound, the first extrusion guide block 182 or the second extrusion guide block 183 releases the product, and the rotation driving part 132 starts and drives the product 17 to rotate by a set angle so as to switch the winding of the next tooth.

When other products need to be replaced for winding, the screw rod assembly 161 is controlled to drive the extrusion block 152 to extrude the outer annular plate 1331 by triggering a preset program, so that the outer annular plate 1331 slides to be aligned and connected with the inner plate 1332, and a structure for pressing and fixing the product with the first specification is formed. Or the lifting frame 131 is controlled to ascend so that the clamping blocks 1334 are in pressing contact with the unlocking piece 1511, and the plurality of clamping blocks 1334 are retracted in a sliding manner, so that the clamping blocks 1334 are disconnected with the clamping holes. Then, under the elastic force of the second spring 1333, the outer ring plate 1331 automatically slides in a direction away from the rotation driving part 132, so that the outer ring plate 1331 and the inner plate 1332 are dislocated, and a structure for pressing and fixing a product with the second specification is formed. Meanwhile, the shaft sleeve 1321 with the corresponding specification needs to be replaced manually through plugging operation.

On the other hand, when the driving rod 186 is manually turned, the connecting section 1861 can squeeze the first elastic positioning block 1872 or the second elastic positioning block 1873 to form a certain elastic movement space, so that the positioning column is convenient to separate from the first positioning hole or the second positioning hole. This causes the connector 188 to rotate about the first axis of rotation 1881, which causes the first and second extrusion guide blocks 182 and 183 to rotate and switch. The manual operation in the process is very simple operation, and the switching is very convenient.

This completes the winding and mode switching process of the winding machine according to the preferred embodiment.

The winding machine is capable of processing multiple products with smaller size specification differences in an adaptive manner through rapidly switching different first extrusion guide blocks and second extrusion guide blocks, and is convenient to operate and high in compatibility through the mode structure of the pressing plate driven by the lifting frame and the extrusion blocks.
