The needle winding mechanism 3 is rotatably connected to the sliding plate 31, which means that the needle winding mechanism 3 can rotate relative to the sliding plate, so that the needle winding mechanism 3 is not hindered by the sliding plate 31 when rotating, but the sliding plate 31 moves along the guide rail 25 to drive the needle winding mechanism 3 to axially move, and thus, the insertion or needle pulling of the needle winding mechanism 3 can be realized by moving the sliding plate 31. Of course, when the revolving spindle 21 revolves, the guide rail 21, the sliding plate 31, and the needle winding mechanism 3 are rotated together.
Here, when inserting or withdrawing a pin, the lead screw motor 612 is operated to drive the lead screw 613 to rotate, the thread kit 614 on the lead screw 613 is guided by the lead screw base 611 and driven by the lead screw 613 to perform a translational motion, after the insert 622 and the slot 311 on the sliding plate 31 are axially aligned on the revolving spindle 21, the lead screw motor 612 stops operating, at this time, the telescopic cylinder 621 is controlled to extend, and the insert 622 is further driven to be inserted into the slot 311 through the through slot 8, and then the lead screw motor 612 is continuously started to drive the needle winding mechanism 3 to move forward or withdraw a pin.
Here, the length direction of the slot 311 on the sliding plate 31 is perpendicular to the axial direction of the needle winding mechanism 3, so that it can be ensured that the plug 622 can still be inserted into the slot 311 through the through slot 8 when the needle winding mechanism 3 rotates with the revolving spindle 21 within a certain angle range.
Preferably, the sliding plate 31 is an annular structure and is recorded as a sliding ring, the sliding ring is concentric with the revolution mandrel 21, the sliding ring is slidably connected with the guide rail 25, the sliding ring is connected with the winding needle mechanism 3 through the mounting seat, the winding needle mechanism 3 is rotatably connected with the mounting seat, a circular slot is formed in the circumferential direction of the sliding ring and is recorded as a circular slot, so that after the winding needle mechanism 3 rotates along with the revolution mandrel 21 and stops at any angle, as long as the through slot 8 on the revolution mandrel 21 and the through slot 8 on the mounting base 1 have a coincident position, the plug-in 622 can penetrate through the through slot 8 and be inserted into the circular slot, the number of the through slots 8 and the circumferential length can be set according to actual conditions, and the structural strength of the revolution mandrel and the mounting base can be guaranteed to the maximum extent.
The terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the feature.
Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
