As shown in fig. 4 to 6, the wire clamping assembly 43 includes a fixed frame 431 connected to the rotating base 42, the fixed frame 431 is provided with a fixed chuck 432 and a movable rod 433 capable of moving back and forth relative to the fixed frame 431, one end of the movable rod 433 is provided with a movable chuck 434 capable of being matched with the fixed chuck 432, the other end of the movable rod 433 is provided with a matching part 435 capable of being matched with the first driving part 411 and the second driving part 412 on the fixed base 41, a return spring 436 capable of pushing the movable rod 433 to return is further disposed between the movable rod 433 and the fixed frame 431, the first driving part 411 is a convex surface disposed on the fixed base 41, and the second driving part 412 is a concave surface disposed on the fixed base 41 and connected with the convex surface. When the wire clamping assembly 43 moves along with the rotating seat 42 and moves from the concave surface to the convex surface, the convex surface on the fixed seat 41 contacts with the matching part 435, the convex surface presses against the matching part 435, so that the moving rod 433 moves relative to the fixed frame 431, and the movable chuck 434 and the fixed chuck 432 clamp the wire 20, and after the wire clamping assembly 43 rotates with the wire 20 at a certain angle (at this time, the wire 20 winds a circle on the annular workpiece 10), the matching part 435 of the wire clamping assembly 43 moves from the convex surface to the concave surface, and in the process of moving from the convex surface to the concave surface, the return spring 436 pushes the moving rod 433 to return, and the movable chuck 434 releases the clamped wire 20, so that the wire 20 can be pulled downwards by the crochet hook 3 to pass through the annular workpiece 10.

As shown in fig. 1, 2 and 7, a retractable clip 6 is further disposed below the thread clamping assembly 43, through which the crochet hook 3 can pass up and down and the thread material 10 can pass, when the thread clamping assembly 43 rotates from bottom to top and contacts with the retractable clip 6, the retractable clip 6 is pushed by the thread clamping assembly 43 to open, and when the thread clamping assembly 43 is separated from the retractable clip 6, the retractable clip 6 is automatically closed. When the wire clamping assembly 43 does not clamp the wire 20, the retractable split clamp 6 is in a closed state, the wire 20 also penetrates through the retractable split clamp 6, the retractable split clamp 6 can limit the wire 20, the sloshing condition can not occur, the wire clamping assembly 43 can clamp the wire 20 easily, when the wire clamping assembly 43 clamps the wire 20 and rotates, the retractable split clamp 6 needs to be opened, the wire 20 can come out from the opening and is wound on the annular workpiece 10, the retractable split clamp 6 is driven by the wire clamping assembly 43 to be opened when the wire clamping assembly 43 rotates, the retractable split clamp 6 is linked with the wire clamping assembly 43, the design is ingenious, and automation is realized.

When the wire clamping assembly 43 clamping the wire 20 rotates, the connecting tube 4315 of the wire clamping assembly 43 abuts against the inclined rod 64, the inclined rod 64 moves in the inclined groove 63, in the process, the inclined rod 64 drives the locking rod to axially move in the sleeve 62, so that the opening of the telescopic open clamp 6 is opened, and after the wire clamping assembly 43 drives the wire 20 out of the opening, the connecting tube 4315 is separated from the inclined rod 64, at the moment, the tension spring 65 pulls the inclined rod 64 to reset, so that the locking rod resets to close the opening, and the wire 20 hooked by the crochet needle 3 again passes through the telescopic open clamp 6 and is limited.

As shown in fig. 2 to 4, the clamping mechanism 1 includes a front clamping assembly 11 and a rear clamping assembly 11, and the fixed seat 41 and the rotating seat 42 are annular structures and are sleeved outside the rear clamping assembly 12. Therefore, the whole automatic hooking and winding device is simple and compact in structure and small in occupied space.

As shown in fig. 1 and 2, a cutting mechanism 7 for cutting the wire 20 after the winding is completed is further provided below the clamping mechanism 1. After the winding of the wire 20 on the entire annular workpiece 10 is completed, the cutting mechanism 7 cuts the wire 20, and then the wound annular workpiece 10 is removed.

In the present embodiment, the annular workpiece 10 is a magnetic ring, but the annular workpiece 10 may be other annular parts requiring winding.
