Description
Technical field
The present invention relates to a kind of shaping mechanism of generator stator of vehicle winding coil, be particularly useful for the coiling moulding of seven pairs of utmost point stator winding coils.
Background technology
According to motor power transfer principle, the core component that motor winding is motor, in the each component parts of motor, its manufacture difficulty maximum, is worth the highlyest, is " motor heart ", therefore, the technical merit of motor winding manufacturing equipment and performance directly affect the manufacture level of motor.Motor winding divides again stator winding and its manufacture difficulty maximum of rotor winding, particularly stator winding, and the technical difficulty of corresponding stator winding manufacturing equipment is also maximum, is wherein equipped for stator winding coil coiling again.The method for winding of domestic traditional stator winding coil is to complete by multiple equipment and operation, and efficiency is lower.Along with the development of equipment technology, the at present domestic full-automatic coil coiling equipment that has also occurred a small amount of collection coiling, taken shape in one, its operation principle is that copper cash is first turned to a circle, then is squeezed into waveform with forming frock.But may causing copper cash to deform, this forming method is unfavorable for rule and the shaping in later stage.In addition, because the motor overwhelming majority is with 2,4,6,8 ... be number of pole-pairs Deng even number, stator winding coil coiling equipment is also corresponding even number number of pole-pairs, and the full-automatic winding coil coiling of 7 pairs of extremely such odd number numbers of pole-pairs is equipped also in space state.And the angle number that even number number of pole-pairs distributes is integer, the angle number that odd number number of pole-pairs distributes is non-integer, so the technical difficulty of the corresponding coiling of odd number number of pole-pairs equipment is higher.
Summary of the invention
The object of the invention is to change the winding mode of the first extrusion modling after circle of existing stator winding coil and a kind of stator winding coil shaping mechanism of limit around edge forming of realizing is provided.
Technical program of the present invention lies in: disc cam is connected in coiling housing big opening end through one with upper guide post; Inlet wire pipe outlet is stretched in the incoming line on disc cam; Disc cam lower surface is provided with curved groove.
Disc cam is loaded on fixed disk inner edge through uiform section thin-wall bearing; Fixed disk outer rim is connected with retainer ring; Retainer ring inwall is along the circumferential direction evenly equipped with N push rod shaping mechanism.
Described push rod shaping mechanism comprise be fixed on retainer ring inwall leg, guide post, be placed in the screw bolt-type outer ring and roll assembly in curved groove; Described guide post is vertical with disc cam central axis; The slide block that can slide along guide post is housed on guide post; On slide block, be connected with for pushing coil so that the push rod of coil molding; Between slide block and leg, be connected with fork; The bearing end of described screw bolt-type outer ring and roll assembly is placed in curved groove, and the bolt end of screw bolt-type outer ring and roll assembly is connected in fork.
Described curved groove is circular, wherein (360/N) degree central angle institute to circular arc radially outwards outstanding so that screw bolt-type outer ring and roll assembly through fork band movable slider slide push rod is moved backward avoid inlet wire pipe to travel forward again copper cash that propelling movement enters from inlet wire pipe enters mould.
Described N is 7.
One of them guide pillar is positioned at the incoming line place of disc cam, and inlet wire pipe is plugged in this guide pillar.
The present invention is by the characteristic of the curved groove track of disc cam own, in its rotary course, drive successively fork, slide block movement, the forming ejector pin on slide block stretches out successively, push the copper cash entering from inlet wire pipe and enter mould, curl up an edge forming on one side thereby realized stator winding coil.
The invention has the beneficial effects as follows: simple in structure, compact, realize the method for winding that stator winding coil curls up an edge forming on one side, not only further improve efficiency, and solved to a great extent and first in aftershaping method, be unfavorable for the problem of later stage rule and shaping because copper cash deforms.
