Coil winding machine for large power three-phase stator coils

Abstract

The invention discloses a coil winding machine for large power three-phase stator coils, comprising a shaft box, a wire laying mechanism, a wire hanging mechanism and a coiling die mechanism, and characterized in that the coiling die mechanism comprises an upper die and a lower die. The upper die and the lower die are symmetrically arranged to the center of a rotary main shaft. The bottom of the upper die and the bottom of the lower die are respectively provided with a pedestal. The upper die and the lower die are connected with a rotating table by a demoulding apparatus through the corresponding pedestal. The demoulding apparatus comprises a contraction cylinder, a central shaft in connection with the contraction cylinder, a contraction linkage in connection with the tip of the central shaft and a guiding mechanism vertically arranged to the rotary main shaft. The central shaft is in sliding connection with the rotary main shaft. The coil winding machine is formed by the upper die and the lower die arranged symmetrically and the dies are connected with the rotary table by the demoulding apparatus, realizing the coiling and automatic demoulding for large power coils with improved production efficiency and coil performance and mitigated labor intensity.

Description

technical field [0001] The invention relates to a winding machine for an induction coil, in particular to a high-power three-phase stator coil winding machine. [0002] Background technique [0003] Three-phase motor means that when the three-phase stator windings of the motor (each with a phase difference of 120 degrees of electrical angle), a rotating magnetic field will be generated after the three-phase alternating current is connected, and the rotating magnetic field will cut the rotor winding, thereby generating an induced current in the rotor winding (rotor The winding is a closed path), and the current-carrying rotor conductor will generate electromagnetic force under the action of the rotating magnetic field of the stator, thereby forming an electromagnetic torque on the motor shaft, driving the motor to rotate, and the direction of rotation of the motor is the same as that of the rotating magnetic field. [0004] The stator coil is one of the important components ...

AI Technical Summary

Problems solved by technology

[0005] The three-phase stator coil winding machine in the prior art is generally used for winding stator coils with a maximum rotation diameter of 0.5m, and is suitable for ordinary low-power three-phase motors such as fan motors, water pump motors, washing machine motors, and air conditioner motors. , when it is necessary to wind a high-power stator coil with a rotation diameter of 0.5m or more, or even 1.2m, because the rotation diameter is too large, the existing mold structure is used again, and the mold unloading and loading are repeated, the labor intensity is too large, and the rotation takes up The volume is too large and difficult to achieve, so it can only be rewinded to manual winding, which greatly affects work efficiency, and the coil consistency is poor
