In upper figure, the corresponding relation between Reference numeral and component names is:
1 frock; 11 briquettings; 12 working bases; 2 tooling connectings; 3 coils; 4 rotation axiss; 5 straight line clamping tools.
Embodiment
Core of the present utility model can prevent that for a kind of end winding device preventing tilting is provided in the bulging process of coil, wire turn inclination inconsistent phenomenon appears in its end, guarantees the evenness of end winding wire turn.
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.Obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1 and Fig. 2, the end winding device preventing tilting that Fig. 1 provides for the utility model embodiment is the structural representation under operating state not; Structural representation under the end winding device preventing tilting operating state that Fig. 2 provides for the utility model embodiment.
As depicted in figs. 1 and 2, the end winding device preventing tilting that the utility model embodiment provides comprises the frock 1 with smooth surface, and this frock 1 is rotatably connected on tooling connecting 2, and the smooth surface of this frock 1 can fit with coil 3.
During work, the straight line portion of coil 3 is undertaken spacing by straight line clamping tool 5, guarantees the evenness of straight line portion wire turn; In the bulging process of the end of coil 3, adjust the position of tooling connecting 2, make frock 1 near the end of coil 3, frock 1 is rotated around tooling connecting 2 simultaneously, make smooth surface and the coil 3 of frock 1 fit, in the process of the Leading Edge Deformation of coil 3, the smooth surface of frock 1 is synchronoused working with the distortion of coil 3, remains and coil 3 is fitted.Thereby make at the wire turn of coil 3 in the process of distortion, its surface is subject to pressure from frock 1 all the time makes it keep applying with smooth surface, makes wire turn not tilt not misplace.Effectively guaranteed the evenness of end winding wire turn.The end bulging enters follow-up top arc operation after finishing, tooling connecting 2 withdrawals this moment.
In actual production process, the forming process of a coil 3 needs an expanding machine to carry out bulging work to four ends of coil 3, and the end winding device preventing tilting that therefore needs four the utility model to provide carries out cooperating.
As seen, the end winding device preventing tilting that the utility model provides by a simple frock, can satisfy the bulging demand of coil of the traction electric machine of different model.Namely not only can prevent the end winding dislocation of tilting, guarantee the evenness of end wire turn, also have simultaneously simple in structurely, easy for installation, versatility is advantage preferably.
