In order to realize above-mentioned purpose of utility model, technical solution is as follows used by the utility model：
A kind of end fixing device of motor rotor coil, including mounting hole, are opened on the magnetic pole pole shoe of rotor；Pressure
Line bar, is fixed in the mounting hole；Binding strap, is wrapped on the end of rotor coil and is connected with the line pressing rod.
In certain embodiments, the outer wall of the line pressing rod is arranged with the wear-resisting casing that insulate.
Further, described sleeve pipe is in arch door shape, and the bottom of the arched door is close to rotor coil.
Further, the inner wall of described sleeve pipe is connected with protrusion；The described raised and outer wall of the line pressing rod is interference fitted.
Further, the protrusion is equipped with four and evenly distributedly ring is located on the inner wall of described sleeve pipe.
In certain embodiments, between magnetic pole pole shoe and iron core, the end fixing device of motor rotor coil is also
Include two catch respectively with the both sides compression fit of rotor coil.
In certain embodiments, a magnetic pole pole shoe includes two mounting holes.
In certain embodiments, the connection mode of the binding strap and the line pressing rod is winding.
The end fixing device of motor rotor coil of the utility model possesses following beneficial effect compared with the prior art：
The end of the binding strap bundled fixed rotor coil, prevents that rotor coil is loose or deforms.The line pressing rod
Be fixed at open up with the mounting hole on magnetic pole pole shoe, the line pressing rod with rotor coil compression fit and with it is described
Bind band connection, rotor coil integrally is fixed together with the line pressing rod, in rotor coil high-speed rotation, rotor coil and
The relative motion of iron core greatly reduces, and then largely reduces the frictional force between rotor coil and iron core, can be as far as possible anti-
The insulation film abrasion coated on rotation stop subcoil.
Brief description of the drawings
Fig. 1 is a kind of cross-sectional partial schematic diagram of end fixing device of motor rotor coil of the utility model embodiment；
Fig. 2 is the enlarged structure schematic diagram at A in Fig. 1.
Embodiment
In order to be fully understood from the purpose of this utility model, feature and effect, below with reference to attached drawing 1 and attached drawing 2 to this
The technique effect of the design of utility model, concrete structure and generation is described further.
A kind of end fixing device of motor rotor coil of the utility model embodiment as shown in Figure 1, including mounting hole
110, it is opened on the magnetic pole pole shoe 1 of rotor；Line pressing rod 5, is fixed in mounting hole 110；Binding strap 4, is wrapped in
It is connected on the end of rotor coil 3 and with line pressing rod 4.
Preferably, the outer wall of line pressing rod 5 is arranged with the wear-resisting casing 6 that insulate.Line pressing rod 5 is directly contacted with rotor coil 3,
Line pressing rod 5 can cause to wear to the insulation film coated on rotor coil 3, and casing 6 is insulation wear-resistant material, it is set in crimping
On bar 5, contacted with rotor coil 3, can effectively prevent the abrasion of insulation film.
Further, as shown in Fig. 2, casing 6 is in arch door shape, the bottom of arched door is close to rotor coil 3.The knot of arch door shape
Structure so that binding compactness of the binding strap 4 on casing 6 is higher, is not easy to loosen.
Further, the inner wall of casing 6 is connected with protrusion 610；Protrusion 610 and the outer wall of line pressing rod 5 are interference fitted.It is raised
610 are interference fitted with the outer wall of line pressing rod 5, and casing 6 is not easy with respect to sliding with line pressing rod 5, and tightness is preferable.
Further, protrusion 610 is equipped with four and evenly distributedly ring is located on the inner wall of casing 6.Four protrusions 610 are equal
Even distribution, the slip of multiple orientation limitation line pressing rods 5 and casing 6.
Preferably, between magnetic pole pole shoe 1 and iron core 7, which has further included difference
With two catch 2 of the both sides compression fit of rotor coil 3.Two catch 2 prevent the end of rotor coil 3 circumferential along rotor
