Description

Stator dip coating peg

Technical Field

The utility model belongs to the technical field of fans, and particularly relates to a stator paint dipping hanging rod.

Background

Patent publication No. CN214682405U discloses a stator dip coating support, which adopts an inverted U-shaped hanger formed by bending a metal strip to hang a stator winding on the dip coating support, and then the stator winding is placed in a glue coating machine for dip coating. In actual production, the hanger adopting the structure is found, paint liquid can be greatly adhered to the hanger, waste is caused (the cost of insulating paint is high), a large amount of adhesion is formed between the hanger and a stator winding, the hanger is difficult to break away in the later period, the hanger can be broken away by continuously forcefully knocking, and the hanger and even a paint dipping support are easily damaged.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a stator paint dipping hanging rod, which can reduce paint adhesion and waste.

In order to solve the technical problem, the utility model adopts the following technical scheme:

a stator dip coating hanging rod comprises a rod body and a hanging frame connected to the end face of the lower end of the rod body, wherein the hanging frame is provided with a plurality of supporting legs which are radially distributed and used for hooking inner hole steps between a stator and a winding, and a hanging hole is formed in the upper end of the rod body.

The pole body design is the three-section, and the lower extreme is the first broadening section that width is greater than interlude width, and the clearance is less than 2mm between first broadening section both sides portion and the stator hole, and the upper end is the second broadening section that width is greater than interlude width.

And two ends of the first broadening section are respectively provided with a chamfer.

According to the stator dip coating hanging rod, the hanging rack is hooked on the inner hole step between the stator and the winding, so that the stator is hung upside down on the dip coating support for dip coating, the hanging rod is less in contact with paint liquid, paint adhesion can be reduced, and waste is reduced; through the gap design of the first widening section, the stator can be prevented from vibrating and falling off from the hanging rack, the paint liquid adhesion at the position is reduced, and the subsequent hanging rod can be conveniently pulled out and separated; in addition, the chamfer design is adopted, so that paint liquid can be promoted to flow downwards, and the adhesion of the paint liquid is reduced.

Detailed Description

The stator dip coating hanging rod comprises a strip-shaped rod body 1 and a hanging frame 2 connected to the end face of the lower end of the rod body 1, wherein the hanging frame 2 is provided with a plurality of supporting legs 3 which are radially distributed and used for hooking inner hole steps 8 between a stator and a winding, the number of the supporting legs is usually three, the upper end of the rod body 1 is provided with a hanging hole 4, and the hanging hole 4 can be a calabash-like hole with a large lower part and a small upper part, and is conveniently sleeved and hung on a corresponding bolt 6 of a dip coating support 5. During the use, can penetrate the hole and wear out from the upper end from stator winding 7 lower extreme with body of rod 1 upper end, the lower extreme passes through stabilizer blade 3 hook on hole step 8, hangs upside down again on dip coating support 5 to make stator winding 7 submerge the lacquer liquid by this dip coating peg and carry out the dip coating. Compared with the existing inverted U-shaped lifting appliance, the contact between the support legs 3 and the stator windings 7 is less, the contact surface of the hanging rod is obviously less, and the phenomenon of paint adhesion is effectively improved.

The rod body 1 can be designed into three sections, the lower end of the rod body is a first widening section with the width larger than that of the middle section, and the gap L between two side parts of the first widening section and an inner hole of the stator is smaller than 2 mm; the upper end is a second widening section with the width larger than that of the middle section, the width is smaller than the diameter of an inner hole of the stator, and the widening design can play a role in increasing the strength of the position, reducing swing and improving stability; while the narrowest intermediate section also serves to reduce paint sticking.

In addition, the two ends of the first widening section are respectively provided with a chamfer 9, particularly the chamfer 9 at the lower end, so that the paint liquid can flow downwards, and the bonding effect of the paint liquid is reduced.

However, those skilled in the art should realize that the above embodiments are illustrative only and not limiting to the present invention, and that changes and modifications to the above described embodiments are intended to fall within the scope of the appended claims, provided they fall within the true spirit of the present invention.
