Description

Technical Field

[0001] This utility model belongs to the field of motor winding mold technology, specifically referring to a motor winding mold with adjustable mold width. Background Technology

[0002] Wound-rotor motors are a type of asynchronous motor. Asynchronous motors are classified into wound-rotor and squirrel-cage types according to the rotor winding form. In the process of thickly stacked stator windings of the motor stator core, a winding mold is required.

[0003] In manual winding of motor stator windings, for stator windings of the same series but with different core thicknesses, a winding die is generally configured for each core thickness. However, when there are many core thicknesses, the number of winding dies will be large, making operation inconvenient and increasing die costs. Therefore, there is an urgent need for a motor winding die with adjustable die width to solve the above problems. Utility Model Content

[0004] The technical problem this utility model aims to solve is a method of configuring a winding mold for stacked iron cores. When there are many specifications of stacked iron cores, the number of winding molds is large, the operation is inconvenient, and the mold cost is high.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a motor winding die with adjustable die width, including multiple base plates and a rotating shaft through hole fixedly set on the base plate. The base plate is also fixedly provided with multiple sets of adjusting screw holes located on the upper and lower sides of the rotating shaft through hole. The base plate is provided with an upper die core, a lower die core and a tightening bolt on both sides, and the base plate is connected to the upper die core and the lower die core through the tightening bolt.

[0006] Furthermore, one of the base plates has a baffle on one side, and the base plate and the baffle are connected by an upper mold core, a lower mold core and a tightening bolt.

[0007] Furthermore, the base plate, the upper mold core, and the lower mold core are all provided with adjustment screw holes of the same specification, and the adjustment screw holes are compatible with the tightening bolts.

[0008] Furthermore, the upper mold core and the lower mold core are provided with a set of adjusting screw holes, and the base plate is provided with three sets of adjusting screw holes in a linear array.

[0009] Furthermore, the baffle is provided with a pivot hole and multiple adjusting screw holes, and the pivot holes on the baffle and the base plate are on the same horizontal line.

[0010] Furthermore, the two base plates are connected by an upper mold core, a lower mold core, and tightening bolts.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows:

[0012] The upper and lower mold cores are fixed by multiple adjusting screw holes between the two base plates. The distance between the upper and lower mold cores is determined according to the stacking thickness of the stator core. The upper and lower mold cores are fixed by tightening bolts screwed into the adjusting screw holes. This allows for the adaptation to stator core stacking thicknesses of different sizes, reducing the number of molds and saving costs. Attached Figure Description
