High-power, slow-speed of revolution frequency control roughing motor is the roughing motor of capacity 7200kW, and number of poles is 16P, and voltage is 3000V, and rotating speed is 40～80r/min, and rotor diameter is 3030mm, and length overall is 7407mm.Usually the processing method of motor pole is that the pole coil insulation against ground is made on the pole body of pole core, also be that pole coil is placed turn-to-turn insulation during coiling on bobbin, installing to iron core at cover goes forward, a series of insulating barriers are being set on the pole body and are being coated with insulating varnish suit coil again after curing, so that the pole coil insulation against ground.This kind method can only be used for short iron core and less magnetic pole, because the pole core length on this roughing motor belongs to king-size, pole coil insulation resistance over the ground will be up to more than 100 megaohms, therefore the insulation against ground of pole coil is the most important thing of this magnetic pole processing, must the corresponding processing tool of supporting employing.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of compaction tool that is used for pole coil is provided, it can guarantee insulation processing effect behind the pole core suit coil, can improve the insulation against ground performance of pole coil effectively and make more fastening that pole coil press-fits.
A kind of technical scheme that realizes above-mentioned purpose is: a kind of compaction tool that is used for pole coil, described magnetic pole comprises pole core and the some dress utmost point screw rods that axially is distributed on the pole core bottom surface with pole body and pole shoe, described pole coil is sleeved on the pole body and is respectively equipped with the magnetic pole liner on the upper and lower end face, described compaction tool is located under the magnetic pole liner of pole coil lower end, and it comprises:
One backing plate, it is a middle frame plate of engraving an oblong aperture, the lower surface of its frame wall and magnetic pole liner are fitted;
With the identical pressing plate of quantity of dress utmost point screw rod, they are an arch lath and offer one respectively in the centre and are used to adorn the through hole that utmost point screw rod passes through, and they axially are connected the upper surface of backing plate in uniform way and removably;
Described dress utmost point screw rod makes magnetic pole be connected with compaction tool by dress utmost point nut after passing the through hole of pressing plate.
The above-mentioned compaction tool that is used for pole coil, wherein, a joint hinge hole is offered at two of described backing plate frame wall respectively.
The above-mentioned compaction tool that is used for pole coil, wherein, two of described pressing plate lower surface is the plane of fitting with the frame wall upper surface of backing plate.
The above-mentioned compaction tool that is used for pole coil, wherein, the centre of described every block pressur plate is provided with a boss, and described through hole is opened in this boss.
The above-mentioned compaction tool that is used for pole coil, wherein, described backing plate is made by the thick A3 steel of 40～44mm.
After having adopted the technical scheme of the compaction tool that is used for pole coil of the present utility model, guarantee the pole insulation treatment effect, can improve the insulation against ground performance of pole coil effectively, make more fastening that pole coil press-fits.In addition, backing plate and pressing plate in the instrument are made composite type, make this instrument have versatility, change as pole dimension, as long as backing plate is changed, have also saved production cost.
