Paper inserting machine of stator core wire embedding slots

Abstract

The invention discloses a paper inserting machine of stator core wire embedding slots, which comprises a worktable, a die device arranged on the worktable and used for assembling stator cores, a paper advance mechanism arranged on the worktable, and an uplifting mechanism arranged on the worktable and used for uplifting shaped insulating paper to the stator core wire embedding slots. The paper inserting machine is characterized by also comprising an indexing mechanism arranged on the worktable, an insulating paper shaping device which can shape insulating paper suitable for various slots, and a controller used for controlling the operation of the indexing mechanism, the insulating paper shaping device and the paper advance mechanism. The output end of the indexing mechanism is engaged with a die gear on the die device, the insulating paper shaping device is located at one side of the paper advance mechanism, and the insulating paper shaping device is located under the die gear of the die device. The invention can complete insulating paper setting in all wire embedding slots to the stator core provided with a plurality of wire embedding slots in one step, and has the advantage of high production efficiency.

Description

technical field [0001] The invention relates to a device for inserting insulating paper into a wire slot of a motor stator core, in particular to a paper insertion machine for a stator core slot. Background technique [0002] On the stator core, there are often multiple embedding slots and embedded field windings to ensure that the motor can work normally. Since the field winding is composed of wires, in order to avoid the conduction between the field winding and the stator core, even if the stator core and the field winding are insulated, there are many methods currently used. First, the stator core is made of injection molding In the first way, an insulating layer with a thickness of 0.5 to 1mm is formed on the wire groove of the iron core and the surface of the iron core; secondly, the insulating paper is inserted into the wire groove by using a paper insertion device. [0003] For the above-mentioned first method, the injection molding process is as follows: firstly, th...

Problems solved by technology

This is not only inefficient, but also during the paper insertion process, the stator core needs to be moved between these devices, and the labor intensity of the operator is also very high
