A winding core mold with a reversible half shaft

Abstract

The present invention discloses a winding core mold with a rotatable half shaft, which includes a winding core mold. A rotating groove is formed on the winding core mold, and a half shaft assembly is arranged in the rotating groove. The half shaft assembly includes a connecting shaft and a half shaft. One end of the connecting shaft is provided with a driving assembly, and a plurality of limiting columns are arranged on the winding core mold. By the combined use of a driving motor, a driving assembly, and a half shaft assembly, when it is necessary to flip the half shaft, the driving motor drives the worm to rotate, so that the worm wheel rotates relative to the winding core mold, and then drives the connecting shaft and the half shaft to rotate relative to the winding core mold, thereby completing the flipping of the half shaft, adjusting the radius of the winding core mold following the rotation of the half shaft, and thus completing the winding radius of the winding core mold. At the same time, the fibers wound are limited by the limiting columns distributed on both sides of the winding path, avoiding the slippage of the glass fibers during winding. Only the threaded column on the side away from the half shaft needs to be removed, and the glass fibers can be quickly removed.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. By the combined use of a driving motor, a driving assembly, and a half - shaft assembly, when the half - shaft needs to be flipped, the driving motor drives the worm to rotate, causing the worm gear to rotate relative to the winding core mold. Then, the connecting shaft and the half - shaft rotate relative to the winding core mold, thus completing the flipping of the half - shaft and adjusting the radius of the winding core mold following the rotation of the half - shaft, and further completing the winding radius of the winding core mold.

[0012] 2. The present invention also, by the combined use of limit posts and threaded holes, limits the wound fibers through the limit posts distributed on both sides of the winding path to prevent slippage during winding. When removing the glass fiber, only the threaded post on the side away from the half - shaft needs to be removed, and the glass fiber can be quickly removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-3 , the present invention provides a technical solution: a winding core mold with a flippable half - shaft, including a winding core mold 1, a rotating groove 2 is opened on the winding core mold 1, a half - shaft assembly 3 is installed in the rotating groove 2, the half - shaft assembly 3 includes a connecting shaft 31 and a half - shaft 32, one end of the connecting shaft 31 is installed with a driving assembly 4, and a plurality of limit posts 6 are installed on the winding core mold 1;

[0019] The connecting shaft 31 is installed in the rotating groove 2 through bearings. The half shaft 32 is sleeved on the connecting shaft 31. An installation hole adapted to the winding machine for clamping and rotating the connecting shaft 31 is provided at the end of the half shaft 32. A cavity is provided in the winding core mold 1. One end of the connecting shaft 31 passes through the outer wall of the cavity to reach the inside of the cavity and is connected to the inner wall of the cavity through a bearing. The driving assembly 4 includes a worm gear 41 and a worm 42. The worm gear 41 is fixedly sleeved on the connecting shaft 31. The worm 42 is installed outside the worm gear 41 in the cavity through a bearing. The worm gear 41 meshes with the worm 42. By using the self-locking characteristic of the worm gear 41 and the worm 42, the connecting shaft 31 and the winding model are limited. One end of the worm 42 is connected with a driving motor 43 through a coupling. The driving motor 43 is connected to the inner wall of the cavity through bolts. The driving motor 43 is electrically connected to an external terminal controller. Eight threaded holes are provided on the winding core mold 1. The eight limiting columns 6 are respectively threadedly connected with the corresponding threaded columns. The eight limiting columns 6 are distributed on the side wall of the winding core mold 1 centered on the connecting shaft 31. The fibers during winding are limited by the limiting columns 6 distributed on both sides of the winding path to prevent the glass fibers from slipping during winding.

[0020] Working principle: When the invention is in use, the half shaft 32 is fixed to the winding machine for clamping and rotating the connecting shaft 31 through the installation hole. During winding, the fibers during winding are limited by the limiting columns 6 distributed on both sides of the winding path to prevent slipping during winding. When removing the glass fibers, only the threaded column on the side away from the half shaft 32 needs to be removed, and the glass fibers can be quickly removed. When the winding radius needs to be adjusted, the driving motor 43 is started. The driving motor 43 drives the worm 42 to rotate, so that the worm gear 41 rotates relative to the winding core mold 1, and then drives the connecting shaft 31 and the half shaft 32 to rotate relative to the winding core mold 1, thereby completing the flipping of the half shaft 32 and adjusting the radius of the winding core mold 1 following the rotation of the half shaft 32, and then completing the winding radius of the winding core mold 1. It has the advantages of a flippable half shaft 32, convenient use, and good use effect.
