Description

A kind of motor welding winding

Technical field

This technology designs machine winding.

Background technique

When the higher conductor production machine winding of use intensity, since conductor bends difficult, the general side using welding Conductor is connected to become winding by method, can only be using the method connection of end welding (welding) due to the space very little between conductor Conductor, as shown in Figure 1-3, two conductors 1,2 pass through the wire casing on iron core 3, the conductor tab 11 of conductor 1 and the conductor of conductor 2 Connector 21 is welded in their end 3, the conductor of this method welding, and the metal link section between two conductors is small, and welds Height is required to fusion joining process in the process, pad current flowing area is small, and accumulates irregularly, it is unfavorable for control of product quality, In addition, welding high temperature also easily causes the damage of enameled wire.

Summary of the invention

It is big that the purpose of the application is to provide the welding position melting area between a kind of conductor, reliable welding quality, winding More efficiently motor welds winding for production.

Motor described in this technology weld winding, the winding at least by two pass through winding slot of core conductor welding and At the connector faying face of two conductors mutually welds.

Above-mentioned motor welds winding, to two conductor tabs in the direction clamping perpendicular to faying face when welding.

Above-mentioned motor welds winding, when welding, first welds to the conductor tab close to iron core axis, then to first welding The connector connect is bent to close to iron core axis direction, after welded to far from the conductor tab of iron core axis；Alternatively, first to remote Conductor tab from iron core axis is welded, then to the connector first welded to far from iron core axis direction bend, after to close The conductor tab of iron core axis is welded；

The connector that first welds is because in the axial direction close to iron core end face, the weld clip being clamped to the connector of rear welding Tool will not interfere with the connector first welded.

Above-mentioned motor welds winding, and welding uses ultrasonic bonding or electric resistance welding.

Above-mentioned motor welds winding, and the conductor tab after welding is bent to close to or far from iron core axis direction, so that Conductor tab is in iron core axial direction close to iron core end face.

This patent the utility model has the advantages that this technology using conductor tab faying face weld, the end relative to conductor tab Welding, then can obtain biggish current flowing area, be beneficial to quality control, and the technique for faying face welding, such as super Sound wave welding, electric resistance welding etc. have higher efficiency and stability compared to end fusion joining process, therefore, faying face Welder Skill has very big advantage.

But faying face welding procedure must be used from the direction clamping conductor ability operation perpendicular to faying face, and around Group is often often that multiple welding points mutually abut in the radial direction of iron core, welding connects made of a plurality of conductor welding Not for the space of the welding fixture operation of clamping conductor between head.In order to solve this problem, when welding, first to close to iron mandrel The conductor tab of line is welded, then is bent to the connector first welded to close to iron core axis direction, after to far from iron core axis Conductor tab welded；Alternatively, first welded to far from the conductor tab of iron core axis, then to the connector first welded to Bent far from iron core axis direction, after welded to close to the conductor tab of iron core axis；The connector first welded is because in axis To the close iron core end face in direction, the welding fixture that the connector of rear welding is clamped will not be interfered with the connector first welded.According to Welding fixture clamping conductor so can be used and welded (such as Fig. 5).

This bending construction, other than working space is conceded in the welding that can be given between subsequent conductor, also shortens winding Axial length, keep winding more compact.

Specific embodiment

Embodiment

Referring to fig. 4, across the weld position schematic diagram of two conductors of winding slot of core, the connector of conductor 1 shown in 5 11 faying faces opposite with the connector 21 of conductor 2 mutually weld, and form welding section 4 in the faying face of the two.

For a motor welding winding, there are multiple windings, each winding there may be multiple welding points, in order to anti- Only narrow space can not use welding fixture between welding point, we use following operation.

Referring to Fig. 6, first two conductor tabs 5 far from iron core axis are welded, when welding uses welding fixture 7 The connector of two conductors is clamped on the direction perpendicular to faying face.After the completion of conductor tab 5 is welded, referring to Fig. 7, then to elder generation Soldered conductor tab 5 is bent to far from iron core axis direction, and conductor tab 5 is moved on the axis direction of iron core 3 Close to the position of core ends, welding is provided convenience for subsequent two conductor tabs 6 welding to close to iron core axis.Weldering When connecing conductor tab 6, clamped on the direction perpendicular to faying face using connector of the welding fixture 7 to two conductors.Because first The conductor tab 5 of welding has been bent close to core ends, will not generate interference with welding fixture 7.The conductor tab 6 welded afterwards After the completion of welding, then conductor tab 6 is folded into the state being substantially flush with the conductor tab 5 first welded, referring to Fig. 8.

Welding uses ultrasonic bonding, electric resistance welding or other welding for enabling to the faying face of conductor to weld together Method.

Certainly when welding, first the conductor tab 6 close to iron core axis can also be welded, then to the conductor first welded Connector 6 is bent to close to iron core axis direction, after welded to far from the conductor tab 5 of iron core axis.

This technology is welded to form the conductor of winding using wire bonding face, can obtain biggish current flowing area, have It is controlled beneficial to quality, and the technique for faying face welding, such as ultrasonic bonding, electric resistance welding, compared to end fusion joining process, It has higher efficiency and stability.

Being welded on the first winding set first, (iron core radial direction leans on the innermost winding or outermost of axial ray Winding) conductor tab, since other windings influence, what the first winding set can be convenient is clamped and is welded using welding equipment Connect conductor；(such as Fig. 6)

Then, then the first winding set is bent outwardly (if it is outermost winding set) or is curved inwardly (if it is Most inner side winding set), working space is conceded in the second winding set welding for that will operate；In this way, when welding the second winding set, according to Welding fixture clamping conductor so can be used and welded (such as Fig. 7).This curved configuration, in addition to subsequent winding set can be given Welding is conceded outside working space, is also shortened the axial length of winding, is kept winding (such as Fig. 8) more compact.

This technology realizes the high efficiency and high reliability production of winding conductor, compared to end welding procedure, efficiency It is higher, and winding is shorter, will play good impetus to the popularization and application of welding winding electric machine.

The present embodiment only illustrates tool, and there are two the winding constructions of winding set and technique, patent claims to be not limited to two A winding set.

The winding set: being welded together to form by least two or more conductor tabs, along iron core axis The conductor connection group of dispersed placement, a winding can be made of multiple winding sets.
