Lifting mechanism for stator winding and stator three-needle winding equipment

Abstract

The invention relates to a lifting mechanism for stator winding and stator three-needle winding equipment. The lifting mechanism comprises an external spline shaft, a first spline nut, an internal spline shaft and a second spline nut, wherein the first spline nut is arranged on the external spline shaft and is driven by a first driving mechanism, the external spline shaft moves in a reciprocating way along a vertical direction with the first spline nut, the second spline nut is arranged on the internal spline shaft and is driven by a second driving mechanism, the internal spline shaft moves in a reciprocating way along the vertical direction with the second spline nut, the internal spline shaft is arranged in the external spline shaft, and the internal spline shaft and the external spline shaft are coaxially arranged. By the stator three-needle winding equipment, a cam and oil box type lifting mechanism in the prior art is improved, a dual-shaft spline structure is employed, a servo motor is used for directly driving, so that a product parameter is simpler and more intuitive to adjust, the winding efficiency is greatly improved, meanwhile, the equipment occupancy area is greatly reduced, and pollution is reduced.

Description

technical field [0001] The invention relates to a lifting mechanism for stator winding and stator three-needle winding equipment with the lifting mechanism, belonging to the technical field of motor production equipment. Background technique [0002] Currently used brushless motor outer stator core winding, such as compressor motor stator, washing machine motor, automobile water pump motor, etc. [0003] In the production process of the outer stator of the brushless motor, the combined telescopic mechanism of the eccentric wheel and the sleeve is used in the commonly used equipment. The stem of the sleeve is connected with the eccentric wheel. The rotation of the eccentric wheel drives the stem to move up and down, and can Circular winding movement of the stator block of a unit relative to the motor stator. [0004] The main disadvantages of this approach include: [0005] 1: The winding stroke is fixed, only suitable for a single size stator, and the scope of application ...

AI Technical Summary

Problems solved by technology

[0005] 1: The winding stroke is fixed, only suitable for a single size stator, and the scope of application is narrow;

[0006] 2: The equipment is bulky and occupies a large area;

[0007] 3: And the eccentric wheel often needs to be used with a lubricating oil tank, and the lubricating oil in the oil tank needs to be replaced regularly, which seriously pollutes the environment;

[0008] 4: Loud vibration and loud noise
