Rotary type winding machine of bicycle motor

Abstract

The invention is an automatic winding machine used for winding a winding of a bicycle motor. The winding machine mainly comprises the functional modules of a rotary winding motion mechanism, a wire pressing motion mechanism, a wire pressing supporting rack height adjusting mechanism, a bicycle motor iron core rotating mechanism, a counting mechanism, a tensioning mechanism and the like, wherein the most remarkable characteristics of the winding machine is that: two opposite circular arc-surface explorators are used for leading enamelled wires to a groove, and the uniform winding is realized by using the wire pressing mechanism to adjust the height of a winding coil. When the enamelled wires are wound around a supporting rack (2), because of the blocking of the circular arc-surface explorators of a back wire rack (36) and a front wire rack (37), the enamelled wires are limited and led to a wire groove between the supporting racks; and when the enamelled wires are wound to the outside of the left side (or right side) of the wire groove, a left wire pressing rack (16)(or right wire pressing rack (21)) is driven by a cam (15) (or a cam (20)) to easily press down the enamelled wires to a proper height. By reasonably adjusting the rotary speed of a left screw rod (17), the heights of the wire pressing supporting racks can be gradually adjusted, so that the uniform winding of the coil is realized, and the winding density of the enamelled wires can be dynamically adjusted and controlled. In the winding process, an enamelled wire roller (34) rotates in the same direction as the winding direction, so that the torsional stress of the enamelled wires generated in the process of winding the coil can be released. The winding machine is characterized in simple structure, high efficiency, low cost and automatic counting, and can be widely used for winding the coil of the motor of the bicycle and the coil similar to the armature.

Description

technical field [0001] The invention relates to a winding machine for winding motor coils, in particular to a rotary bicycle motor winding machine capable of winding high-density multi-slot iron core coils. Background technique [0002] Motor rotors, especially the rotor cores of integrated motors such as electric bicycles and motorcycles, usually have various types and complex structures. At present, the most commonly used motors for electric bicycles are brushed toothless motors and brushless toothless motors. The difference between a brushed motor and a brushless motor is that a brushed motor is mechanically commutated by a carbon brush and a commutator, while a brushless motor senses a signal through a Hall element and is electronically commutated by a controller. [0003] There are many types of brushed toothless motors. Brushed toothless motors are mainly composed of rotor coils, stator magnets, left and right side covers, carbon brushes, commutators, motor shafts and ...
