Abstract
Disclosed is a processing method for shielding a motor rotator. Two shielding plates are covered on the shaft when a rotator is processed by rough machining; then the connection part between the shaft and the shielding plate is processed by argon arc welding; then a stainless steel thread is welded by fusion welding on the base to achieve a sealing function; then the rotator is processed by finish machining and a rotator shield cover is installed; and then the rotator is put into an oven and kept at the temperature of 250 DEG C for 4-5 hours to vaporize the moisture out of the rotator inner cavity from the leakage detecting hole by high temperature; after that, the rotator is taken out and the leakage detecting hole is immediately sealed by argon arc welding; and then the rotator can be moved to following processes. Compared with prior art, firstly, the method solves the problem of leaving moisture in the rotator and effectively avoids the bulge phenomena of the rotator shield cover; secondly, the rotator is sealed after being in 250 DEG C for long time, the shield cover can shrink and closely cling to the outer diameter of the rotator iron core after cooling, making the place thereof gapless; moreover, the shield cover will not distort in the future when the pump works because the shield cover performs a certain of thermal expansion and cooling contraction at the situation above the working status.
Description
Technical field
The present invention relates to electromechanical equipment manufacturing technology field, the concrete processing method that relates to a kind of shielding motor rotor.
Background technology
Shield electric machine generally is used to be installed in all kinds of HVAC water pumps, but because the problem of existing processing technology often makes motor in use for some time, rotor shielding sleeve produces and expands or bulge, thereby causes all kinds of problems.
Referring to Fig. 1, shielding motor rotor comprises, one 5, be with unshakable in one's determination 6 on the axle, 6 two ends unshakable in one's determination are provided with screen board 2,3,6 outsides unshakable in one's determination are with housing 4, its processing method is generally, two rotor screen boards 2,3 through after the heat in time hot charging on axle 5 shown in Figure 1, the contraction of screen board internal diameter seals with clamp shaft 5 after waiting its natural cooling, go up lathe fine finishining rotor diameter again, afterwards rotor shielding sleeve 4 shown in Figure 1 is pressed into rotor core 6 external diameters, then with housing 4 two ends and two screen boards 2,3 usefulness argon arc weldings are welded, and put into water by the compressed air that bores in advance good leak hunting aperture 1 and frock input certain pressure on the screen board again and hunt leak, and confirm to carry out the next procedure of rotor again with argon arc welding good seal leak hunting aperture after qualified.This processing technology exists certain defective, promptly in the course of processing, easily from leak hunting aperture 1, enter moisture, these moisture just exist in the rotor shielding sleeve 4 behind the good seal, and these moisture expanded by heating make 4 bags of its housing and stator can friction cause the housing breakage to cause the certain quality problem in the back actual motion that dispatches from the factory.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the problem that existing rotor processing method exists, and a kind of processing method of shielding motor rotor is provided.
In order to address the above problem technical scheme of the present invention is such:
A kind of processing method of shielding motor rotor is characterized in that, may further comprise the steps:
After rotor roughing, weld two screen boards on armature spindle, the fine finishining rotor diameter is installed rotor shielding sleeve in rotor core, leak detection, oven dry, sealing leak hunting aperture.
Described welding two screen boards are specially elder generation two screen boards directly are enclosed within on the axle on armature spindle, feel secure with argon arc welding in the junction of axle and screen board then, again with stainless steel strand melting welding sealing.
Described oven dry is specially and rotor part is put into baking oven kept under 250 ℃ state 4～5 hours, and the moisture of rotor internal cavity is evaporated from leak hunting aperture through high temperature.
Described sealing leak hunting aperture is specially after rotor takes out from baking oven, adopts the argon arc welding sealing immediately, avoids moisture to enter in the housing once more.
Beneficial effect, compared with prior art, the one, solved the leftover problem of internal rotor moisture, removed the phenomenon of rotor shielding sleeve bulge, eliminated the quality problems that very big part produces because of the rotor problem; The 2nd, rotor is sealed again after being under 250 ℃ of states for a long time, housing shrinks and to be close to the rotor core external diameter and to have no the gap between making it after the cooling, in addition housing be higher than passed through certain expanding with heat and contract with cold under the situation of working condition after, the situation of housing distortion can not appear when pump work later again.
Description of drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is a rotor structure schematic diagram of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 1, shielding motor rotor comprises, one 5, be with iron core 6 on the axle, 6 two ends unshakable in one's determination are provided with screen board 2,3,6 outsides unshakable in one's determination are with housing 4, processing method of the present invention is: after rotor roughing, two screen boards 2,3 directly are enclosed within on the axle 5, feel secure with argon arc welding in the junction of axle 5 and screen board 2,3 then, use the melting welding of stainless steel strand again, on this basis to reach sealing function; Then, go up lathe fine finishining rotor diameter again, rotor shielding sleeve shown in the figure 4 is pressed on rotor core 6 external diameters afterwards, putting into water by the compressed air that bores good leak hunting aperture 1 and frock input certain pressure on the screen board 2 in advance again hunts leak, after leak detection is qualified, rotor part is put into baking oven to be kept under 250 ℃ state 4～5 hours, the moisture of rotor internal cavity is evaporated from leak hunting aperture 1 through high temperature, takes out rotor afterwards and leak hunting aperture 1 usefulness argon arc welding good seal is entered next procedure more at once.
Compared with prior art, the one, solved the leftover problem of internal rotor moisture, removed the phenomenon of rotor shielding sleeve bulge, eliminated the quality problems that very big part produces because of the rotor problem; The 2nd, rotor is sealed again after being under 250 ℃ of states for a long time, housing shrinks and to be close to the rotor core external diameter and to have no the gap between making it after the cooling, in addition housing be higher than passed through certain expanding with heat and contract with cold under the situation of working condition after, the situation of housing distortion can not appear when pump work later again.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
