Abstract

The utility model relates to an internal arrangement stator direct wire winding device, which is composed of a synchronizing wheel, a big spline, and a big shaft coupling, wherein the dynamic force in rotary movement can be converted into vertical direction movement by the big shaft coupling and a small shaft coupling which are arranged on the utility model, and then, the vertical direction movement is converted into straight line telescopic movement of a wire mouth by a winding displacement shifting fork; thereby, the winding displacement and the wire winding functions of an inner part can be realized. The utility model has the advantage of compact structure; furthermore, the utility model can fully utilize the space in a groove, and stators with higher groove-filling rate can be wound.

Description

The direct Winder of internal discharging type stator

Technical field: the utility model relates to a kind of Winder, particularly relates to the direct Winder of a kind of internal discharging type stator.

Technical background: existing direct coil winding machine, mainly be that the line mouth is when walking fixation locus, on distinctive slip mould, line slips into the tooth portion of stator again by the gradient of mould with wire-wound, thereby reaches the purpose of winding displacement by the drop point of winding displacement mould rectilinear motion change line in the horizontal direction.Its shortcoming mainly contain following some:

1, when coiling must be with wire-wound externally on the mould, and the gradient by mould slips into the tooth portion of stator with enamelled wire, so the line mouth must be according to bigger orbiting motion during winding displacement.The negative effect of the bigger band rice of the track that the line mouth is walked then is: the drop point of enamelled wire can be very inaccurate when a, winding displacement, thereby it is netted that coil is lined up.Space between line and the line can't obtain utilizing, and the winding volume that winds up like this will be bigger than normal.The tension force of b, coil is inhomogeneous, and enamelled wire might be by drawing-down, break.In the time of the higher stator of coiling copper factor, very possible like this because coil is excessive, when move, the line mouth abrades enamelled wire in groove, cause the bad of product.

2, the product quality is subjected to the influence of slip mould bigger.When enamelled wire slides, can influence the quality of product because factors such as the gradient of rough, the mold design of mould, turning cause the damage of enamelled wire on mould.

3, coil is irregular.

The purpose of this utility model will provide a kind of internal discharging type stator direct Winder exactly, when coiling, linear telescopic motion by line mouth horizontal direction realize inner row around, can make coil arrangement neat, reduce the volume of coil, make full use of the interior space of groove of stator, can the higher stator of coiling copper factor.

Summary of the invention: the purpose of this utility model is to realize like this, internal discharging type linear stator Winder is made up of synchronizing wheel, big spline, big shaft coupling, it is characterized in that: between shift fork push-plate and synchronizing wheel, be provided with big shaft coupling and little shaft coupling, use big splined between described synchronizing wheel and the big shaft coupling, adopt little splined between described little shaft coupling and the shift fork push-plate; Described shift fork push-plate is provided with the winding displacement shift fork, and an end of winding displacement shift fork connects with the line mouth.The utility model compact conformation does not need outside any mould, has reduced because of the damage of other external factor to enamelled wire.

Description of drawings: the structural representation of Fig. 1 unabridged version utility model.

1, line mouth 2, stator core 3, winding displacement shift fork 4, shift fork push-plate 5, little spline 6, little shaft coupling 7, big shaft coupling 8, big spline 9, synchronizing wheel

Concrete execution mode: down and the utility model is described in further detail in conjunction with the accompanying drawings

In the drawings, the direct Winder of the utility model internal discharging type stator is made up of synchronizing wheel 9, big spline 8, big shaft coupling 7, it is characterized in that: between shift fork push-plate 4 and synchronizing wheel 9, be provided with big shaft coupling 7 and little shaft coupling 6, connect with big spline 8 between described synchronizing wheel 9 and the big shaft coupling 7, the little spline 5 of employing connects between described little shaft coupling 6 and the shift fork push-plate 4; Described shift fork push-plate 4 is provided with winding displacement shift fork 3, and an end of winding displacement shift fork 3 connects with line mouth 1.The utility model compact conformation does not need outside any mould, has reduced because of the damage of other external factor to enamelled wire.During concrete enforcement, power is transferred on the synchronizing wheel 9, utilize the principle of screw thread pair, power is through will the rotatablely move motion of the vertical direction that changes inner spindle into of big shaft coupling 7, little shaft coupling 6, utilize two cover shaft joints to eliminate the rotatablely move component of shift fork push-plate 4 simultaneously, reach the purpose of transmission with respect to spindle rod; Again vertical motion is changed into the motion that line mouth 1 is made horizontal direction through winding displacement shift fork 3, with wire-wound to stator core, when coiling, linear telescopic motion by line mouth horizontal direction realizes inner winding displacement, can make coil arrangement neat, reduce the volume of coil, make full use of space in the stator slot, can the higher stator of coiling copper factor.Advantage of the present utility model has: 1, utilize servo motor to drag synchronizing wheel rotation, can realize line mouth row around the time linear uniform motion, and the speed can control winding displacement very easily time the and the position of line mouth winding displacement.2, do not need outside any mould, reduced because of other external factor enamelled wire is damaged.3, the main shaft very little track that only need move just can be with wire-wound to stator, and it is neat to help coil arrangement, dwindles the volume of coil, improves the attractive in appearance and quality of product.4, mechanism is simple and reliable.
