Description

Hollow cup coil winding shaping structure Technical Field The utility model relates to the technical field of hollow cup coils, in particular to a hollow cup coil winding shaping structure. Background The coreless rotor structure is widely applied to the high-precision fields of aerospace, precise instruments, medical equipment, servo motors and the like by virtue of the excellent performances of low inertia, high efficiency, quick response and the like. However, the production process of the traditional hollow cup coil has technical bottlenecks of low efficiency, poor precision, insufficient automation degree and the like for a long time, and severely restricts the large-scale application and cost control of the traditional hollow cup coil; in the prior art, the winding of the hollow cup coil mainly depends on semi-automatic or manual operation, a shaft branch (coil framework) is fixed by a manual or simple clamp, then a single-head winding machine is utilized for single-layer winding, dislocation or uneven density among coil layers is easily caused by shaft branch positioning deviation in the winding process, after the single-layer winding is completed, the shaft branch is required to be clamped again by a disassembling die for reverse winding, the operation is complex, and the symmetry of a double-layer coil is difficult to ensure. Disclosure of utility model Aiming at the defects in the technology, the utility model provides a hollow cup coil winding shaping structure. In order to achieve the purpose, the hollow cup coil winding shaping structure comprises a winding assembly and a limiting assembly, wherein the limiting assembly is arranged on the inner side wall of the winding assembly and is convenient for limiting the winding assembly, the winding assembly comprises a winding die holder and shaping blocks, at least two shaping blocks are arranged at one end of the winding die holder, shaping dies are arranged outwards of the shaping blocks, and at least two shaping dies are arranged on one side wall of the shaping blocks. As further illustration, the shaping block is provided with an axial branch extending inwards, the axial branch is arranged on the inner side wall of the shaping block, a winding product is sleeved on the axial branch extending inwards, and the winding product is arranged on the inner side wall of the axial branch, so that the winding of the coil is facilitated. As further illustration, the limiting component comprises an upward pressing protective sleeve, the upward pressing protective sleeve is arranged at one end of the shaft branch, and a downward pressing protective sleeve corresponding to the upward pressing protective sleeve is arranged at one end of the shaft branch. The shaping block is characterized by further comprising a groove and a limiting block, wherein the groove is formed in the inner side wall of the shaping block, and the limiting block is arranged on the inner side wall of the winding die holder and is convenient to limit the shaping block.
