Abstract
The invention relates to a motor rotor with a vacuum welding structure. The motor rotor with the vacuum welding structure comprises a guide bar and an end ring, wherein the end ring is arranged at one end of the guide bar in a vacuum welding mode, the size of a gap I between the guide bar and each of the two ends of the end ring is smaller than that of a gap needed by capillarity, a gap II between the guide bar and the middle of the end ring is matched with the gap needed by capillarity, and a brazing filler metal groove is formed in the outer surface of the guide bar or the inner surface of the end ring, and is formed in the position of the gap II. According to the motor rotor with the vacuum welding structure, due to the fact that the size of the gap I between the guide bar and each of the two ends of the end ring is smaller than that the gap needed by capillarity, after brazing filler metal melts, the brazing filler metal cannot flow away; due to the fact that the gap II between the guide bar and the middle of the end ring is just matched with the gap needed by capillarity, when heating is carried out in a vacuum environment, the brazing filler metal in the brazing filler metal groove permeates the position, needing brazing, between the guide bar and the end ring due to capillarity until the position is full of the brazing filler metal, and welding is complete.
Description
Technical field
The present invention relates to field of motor manufacturing, relate in particular to a kind of rotor of vacuum welding structure.
Background technology
Application number is: 201210485710, name is called " a kind of vacuum welding method of rotor ", a kind of vacuum welding method of rotor is disclosed, rotor in this method is formed by sliver and end ring welding, the sliver of this rotor and end ring position structure are: be inserted on sliver in end ring gap, be provided with solder layer at gap location, for the abundant welding that realizes end ring and sliver is provided with supplemental layers, the rotor of this structure is because the gap of sliver and end ring cylindrical hole is very little, after solder fusing, enter the distance in sliver and end ring cylindrical hole gap by capillarity limited, can not fill fully the gap of sliver and end ring cylindrical hole and leave part defect, and supplemental layers does not have the solder effect that supplements after fusing because Action of Gravity Field can partly flow out the mating surface of end ring and sliver.
Summary of the invention
The object of the invention is to overcome above defect, a kind of rotor that welds sufficient vacuum welding structure is provided.
Technical scheme of the present invention is: a kind of rotor of vacuum welding structure, it comprises sliver and end ring, end ring is the one end at sliver by vacuum welding, the gap I at described sliver and end ring two ends is less than the required gap of capillarity, the required gap of gap II in the middle of sliver and end ring and capillarity matches, in the position of gap II section, in described sliver appearance or end ring, table is provided with solder trough.
Preferably, described solder trough is located at sliver appearance.
Stressed in order to be beneficial to, described solder trough is located at the outer end of II position, sliver gap section.
Preferably, after vacuum welding, after vacuum welding, described end ring end face is carried out to overall processing processing, end ring and sliver outer end portion along solder trough place whole removing except solder trough and respective width.
Preferably, in order to reduce processing capacity, after vacuum welding, described end ring end face is carried out to local processing processing, remove end ring and the sliver outer end portion of solder trough and matched position along solder trough place.
Useful technique effect of the present invention is, the gap between two ends I of sliver and end ring is less than the required gap of capillarity, after solder fusing, can not flow away, the intermediate space II of sliver and end ring just in time matches with the required gap of capillarity, while heating under vacuum, solder in solder trough permeates soldering place that needs of full sliver and end ring under capillarity, and welding fully.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Embodiment mono-: with reference to accompanying drawing, a kind of rotor of vacuum welding structure, it comprises end ring 1, sliver 2, iron core 3 and motor shaft 4, described motor shaft 4 is inserted in iron core 3 by designing requirement, described sliver 2 is all inserted in the corresponding sliver groove of iron core 3, and the center line that guarantees all sliver 2 end cylinders at the center take motor shaft 4 on the same circle in the center of circle, and the end face of all slivers 2 ends is in one plane, described end ring 1 is the two ends at sliver 2 by vacuum welding.The end of sliver 2 adopts the structure of step column type, the end of sliver 2 is lead 6 foremost, the front end of lead 6 does rounded corner processing, after lead 6, be provided with solder trough 7, after solder trough 7, be provided with capillary channel 8, after capillary channel 8, be provided with reference column 9, the middle part of sliver 2 be trapezoidal and with iron core 3 on the size of sliver groove match.Described lead 6, reference column 9 are less than the required gap of capillarity with the gap I at end ring 1 two ends, hole, and the required gap of the gap II in the middle of capillary channel 8 and end ring 1 hole and capillarity matches.
With reference to accompanying drawing 2, sliver 2 and end ring 1 process after the size that meets designing requirement, before assembling, need first the impurity such as oxide and greasy dirt on sliver 2 and end ring 1 to be cleaned out, first by interior the solder trough of the sliver processing 27 preset approximately 5 grams with the fixing powdered filler metal 5 of binding agent or brazing wire 5, then by the lead 6 on sliver 2, sliver 2 is inserted in end ring 1 hole, guarantee the gap uniformity of the outer wall of capillary channel 8 and the inwall in end ring 1 hole by the acting in conjunction of lead 6 and reference column 9.End ring 1 is enclosed within to the two ends of sliver 2, requires the whole end ring hole on end ring 1 corresponding one by one with the center line of whole sliver 2 end cylinders, then rotor carries out vacuum brazing.Complete after vacuum welding at rotor, retain solder trough 7 and lead 6 on rotor, the final rotor that meets designing requirement that forms.
Embodiment bis-: with reference to embodiment mono-, wherein the postwelding structure of rotor is treated to: complete after vacuum welding at rotor, end ring 1 is carried out to local processing processing, remove solder trough 7 and lead 6 on rotor, as shown in Figure 4, the final rotor that meets designing requirement that forms, all the other are identical with embodiment mono-.
