Compound movement winding machine for large-and-middle-scale motor coil

Abstract

The invention discloses a compound movement winding machine for a large-and-middle-scale motor coil, belongs to the technical field of the large-and-middle-scale motor coil winding machine, and mainly overcomes the shortcoming of drastic fluctuation of winding speed of the original large-and-middle-scale motor coil winding machine. A pure rotation winding way of the original large-and-middle-scale motor coil winding machine is replaced by a compound movement winding way which comprises movement and rotation; the biggest characteristic of the compound movement winding machine is that the problem of the drastic fluctuation of winding speed of the original winding machine is fundamentally solved; in addition, the winding machine is also simple in structure, practical, and reliable; and the compound movement winding machine is mainly used for a winding procedure of the large-and-middle-scale motor coil.

Description

technical field [0001] The invention belongs to the technical field of winding machines for large and medium-sized motor coils. Background technique [0002] At present, in all domestic and foreign motor manufacturing industries, the winding method of the coil is still generally: the coil winding die is fixed on the main shaft of the winding machine, and the winding die is driven by the main shaft of the winding machine to rotate at a constant speed , so that the electromagnetic wire is wound round by round on the winding die, thereby completing the winding process of the motor coil. This coil winding method is more suitable for small motors, but it seems somewhat insufficient for large and medium-sized motors. The reason is: in the manufacturing industry of large and medium-sized motors, the coils are generally designed and manufactured as long-waist (or long keyway) coils first, and the ratio of length to width is relatively large, generally 20 to 80 times. between.

Problems solved by technology

Even if the main shaft of the large and medium-sized motor coil winding machine (hereinafter referred to as: the original winding machine) is automatically speed-regulated (the technical measures of using different rotational angular speeds for the main shaft between 360 degrees of rotation), it is only Only the effect of a slightly smaller fluctuation range can be obtained, and it is impossible to fundamentally change the phenomenon of fluctuations in the winding speed and tension force of the original winding machine when winding.
