Description

Stator winding fixture

The invention is related to the winding treatment of a stator, in particular to a high winding efficiency and a non-integrally formed stator winding.

Traditionally, the winding of the motor stator can be divided into two types, one is winding directly on the stator tooth portion of the motor body, and the other is using a stator winding fixture, with a wire frame cover or a release paper (such as but not limited to a Mylar piece). ) to assist in the use.

The conventional stator winding jig has a body with an integrally formed structure and a wire frame. The body has a convex body (equal to the width of the stator teeth) for the wire frame to be sleeved on the periphery of the convex body. A copper wire is wound around the wire frame to form a coil. The conventional stator winding jig will squeeze the wire frame when the copper wire is tightly wound on the wire frame cover, so that the wire frame cover is damaged, the wound copper wire coil is loosened, or the wire frame cover is excessive. Extrusion does not easily detach from the projections, thus reducing overall winding efficiency.

In the practice of the practice, the use of alcohol copper wire instead of ordinary copper

Line, but its cost burden is high, which is not conducive to large-scale production of the industry. Moreover, since the body of the conventional stator winding jig is integrally formed, one body can only be matched with a single type of wire frame cover, and the use is less elastic.

Moreover, in order to customize the stator winding fixture that can be automatically produced, it is necessary to make a number of modules and then combine them. Usually, the suitable stator winding machine is expensive, and it cannot be directly installed on the conventional automatic stator winding machine. .

In view of this, how to eliminate the above-mentioned deficiencies is the technical difficulty point to be solved in this case.

An object of the present invention is to provide a stator winding jig, which can It is not easy to be damaged when the wire frame is detached, and the winding efficiency is improved.

Another object of the present invention is to provide a non-integrally formed stator winding jig that can be customized and can be applied to a conventional stator winding machine.

In order to achieve one or all of the above or other objects, the present invention provides a stator winding jig comprising a base, a transmission portion, a protrusion, a pushing member and a wire holder. The base has a top surface and a bottom surface. The transmission portion is disposed on the bottom surface of the base and provides a transmission source of the stator winding fixture. The protrusion has one end disposed on a top surface of the base. The pushing member has a through hole which is sleeved on the convex body and movable relative to the convex body. The wire rack sleeve has a hollow portion which is sleeved on the convex body, wherein the pushing member is disposed between the base and the wire frame sleeve.
