Abstract
The utility model discloses a kind of stator punching, its drip irrigation device be described winding slot two side be distributed with several to punching body central tilt locking caulking groove, copper wire is around entering in winding slot, to embed in locking caulking groove around the part copper wire entered in winding slot, coating insulating varnish is being carried out to copper wire, make to be bondd by insulating varnish between copper wire and between copper wire and winding slot, because locking caulking groove tilts to punching body central, thus make the opening direction of locking caulking groove contrary with copper wire moving direction, after insulating varnish part drops, copper wire is subject to the resistance of locking caulking groove, and be subject to the locking copper wire of caulking groove resistance and the copper wire in winding slot and bondd by insulating varnish, effectively avoid copper wire to come off in winding slot, and locking caulking groove improves the contact area with copper wire, effectively raise the frictional force between copper wire, good positioning action is served to copper wire simultaneously, avoid copper wire and produce displacement or distortion.
Description
Technical field
The utility model relates to a kind of field of motor manufacturing, and more particularly, it relates to a kind of stator punching.
Background technology
Stator punching is after being stacked into stator, and copper wire is around on winding slot, and people copper wire surface more after fixation coat insulating varnish, and insulating varnish can prevent copper wire from leaking electricity, and also effectively makes the fixing of copper wire and stator punching.
Run at motor start, anxious the factor effect such as to stop under, copper cash is by the impact of electromagnetic force, thermal effect and mechanical stress, the vibration occurred under serious short-circuit conditions in addition and impact, the insulating varnish causing part to contact with stator punching drops, make copper cash may occur that distortion and displacement even produce at winding slot to come off, therefore need winding to be fixed in winding slot reliable, copper cash and winding slot must be made to have good Mechanical Contact, play anti-loosing effect.Traditional locking measure is wound around low-resistance irony asbestos yarn at copper cash outer surface, but anti-loosing effect is still not ideal enough.
Utility model content
For the deficiency that prior art exists, it is fixing more tight that the purpose of this utility model is to provide a kind of copper wire, avoids producing the stator punching come off.
For achieving the above object, the utility model provides following technical scheme: a kind of stator punching, comprise punching body, punching body excircle is provided with some cramp grooves, described punching body inner periphery is provided with some winding slots, and described winding slot two side is distributed with several locking caulking grooves tilted to punching body central.
Preferably, described locking caulking groove is provided with fixing hole away from winding slot one end, and described locking caulking groove communicates with fixing hole.
Preferably, the width of described locking caulking groove near fixing hole one end is less than the width of the other end.
Preferably, the angle that described locking caulking groove and winding slot sidewall are formed is 10-15 degree.
Preferably, the angle that described locking caulking groove and winding slot sidewall are formed is 15 degree.
Preferably, described locking caulking groove is uniformly distributed along winding slot side wall length direction.
Compared with prior art, the beneficial effects of the utility model are: copper wire is around entering in winding slot, to embed in locking caulking groove around the part copper wire entered in winding slot, coating insulating varnish is being carried out to copper wire, make to be bondd by insulating varnish between copper wire and between copper wire and winding slot, because locking caulking groove tilts to punching body central, thus make the opening direction of locking caulking groove contrary with copper wire moving direction, after insulating varnish part drops, copper wire is subject to the resistance of locking caulking groove, and be subject to the locking copper wire of caulking groove resistance and the copper wire in winding slot and bondd by insulating varnish, effectively avoid copper wire to come off in winding slot, and locking caulking groove improves the contact area with copper wire, effectively raise the frictional force between copper wire, good positioning action is served to copper wire simultaneously, avoid copper wire and produce displacement or distortion.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model stator punching embodiment;
Fig. 2 is the enlarged drawing of A in Fig. 1.
Reference numeral: 1, punching body; 2, cramp groove; 3, winding slot; 31, locking caulking groove; 32, fixing hole.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model stator punching embodiment is described further.
A kind of stator punching, comprise punching body 1, punching body 1 excircle is provided with some cramp grooves 2, described punching body 1 inner periphery is provided with some winding slots 3, described winding slot 3 two side is distributed with several to the centroclinal locking caulking groove 31 of punching body 1, copper wire is around entering in winding slot 3, embed in locking caulking groove 31 by around the part copper wire entered in winding slot 3, coating insulating varnish is being carried out to copper wire, make between copper wire and bondd by insulating varnish between copper wire and winding slot 3, because locking caulking groove 31 is centroclinal to punching body 1, thus make the opening direction of locking caulking groove 31 contrary with copper wire moving direction, after insulating varnish part drops, copper wire is subject to the resistance of locking caulking groove 31, and be subject to the locking copper wire of caulking groove 31 resistance and the copper wire in winding slot 3 and bondd by insulating varnish, effectively avoid copper wire to come off in winding slot 3, and locking caulking groove 31 improves the contact area with copper wire, effectively raise the frictional force between copper wire, good positioning action is served to copper wire simultaneously, avoid copper wire and produce displacement or distortion.
Locking caulking groove 31 is provided with fixing hole 32 away from winding slot 3 one end, described locking caulking groove 31 communicates with fixing hole 32, the copper wire entered in locking caulking groove 31 enters in fixing hole 32, enter the clogging locking caulking groove 31 of multiple copper wires in fixing hole 32, the copper wire entered in fixing hole 32 is effectively avoided to move in locking caulking groove 31, thus effectively avoid copper wire and come off, improve fixing effect.
The width of locking caulking groove 31 near fixing hole 32 one end is less than the width of the other end, when copper wire embeds locking caulking groove 31, side along locking caulking groove 31 enters in fixing hole 32, people are made to load copper wire to fixing hole 32 more convenient, and the effective width reducing connector between fixing hole 32 and locking caulking groove 31, effectively decrease the probability that copper wire departs from from fixing hole 32, effectively raise the fixed effect of copper wire.
The angle that locking caulking groove 31 and winding slot 3 sidewall are formed is 15 degree, and the direction that copper wire is departed from and locking caulking groove 31 direction are 165 degree, effectively prevent copper wire along the landing of locking caulking groove 31.
Locking caulking groove 31 is uniformly distributed along winding slot 3 side wall length direction, such arrangement is beneficial to processing and manufacturing, and locking caulking groove 31 is smaller, uniform words can make adjacent between intensity keep certain, avoid the individual intensity anti-loosing effect that causes not of uniform size to occur partial error's alienation.
