For injection moulding is fixed between described boss and coil panel 10.
Described coil panel 10 is provided with stop tooth 101.
Also comprise commutator 14, carbon brush 11, described commutator 14 is fixed on the minor axis end of motor shaft 1, and minor axis end is positioned at electric machine casing 8; Carbon brush 11 is fixed on brush station 16 by torsion spring 13 and carbon brush fixed axis 12; Brush station 16 is fixed on electric machine casing 8; Wherein, the distance of back-up ring 4 to motor magnetite seat 6 end face is greater than to the distance of carbon brush fixed axis 12 bottom commutator 14.
Go out axle head at described commutator 14 to add an insulation spacer 22 and adding a metallic gasket 15, and metallic gasket 15 is welded on motor shaft 1 tail end.
Present invention also offers a kind of fuel gas shooting nail device, comprise anti-knock shock resistance force motor, the end that the motor shaft 1 of described anti-knock shock resistance force motor stretches out described electric machine casing 8 is fixed with ventilating fan 26.
Below in conjunction with Fig. 6 and Fig. 1 to Fig. 5, the fuel gas shooting nail device of the present embodiment and the course of work of anti-knock shock resistance force motor thereof are described in detail, when fuel gas shooting nail device, combustion gas is in cavity implode, and the blade of ventilating fan 26 is subject to the jerk power in A direction in the axis of motor shaft 1; The blade drive motor axle 1 of ventilating fan 26 and locating snap ring 2 are rapidly to A direction and move, and locating snap ring promotes back-up ring 4, and back-up ring 4 promotes clutch shaft bearing 5, and then extruding Compress Spring 7, when the outer ring of back-up ring 4 touches motor magnetite seat 6, stop mobile.Because locating snap ring 2 and back-up ring 4 are subject to motor magnetite seat 6 reaction force each other, therefore locating snap ring 2 and the fixed form of motor shaft 1 need very firm.Preferably add alignment pin in the present embodiment and run through motor shaft 1 and the fixed form adding welding, thus when solving Reusability locating snap ring 2 loosen and the problem that comes off.
Move because rotor is rapidly to A direction after gas explosion, when back-up ring 4 touches motor magnetite seat 6, coil 9 and coil panel 10, between coil panel 10 and motor shaft 1 because inertia produces relative tension, therefore coil 9 and coil panel 10, that fixed form between coil panel 10 and motor shaft 1 needs is very firm.In the present embodiment, coil panel 10 is provided with stop tooth 101 pairs of coils 9 to be fixed, the minor axis end of motor shaft 1 is provided with boss 81, coil panel 10 injection moulding is fixed on boss 81, thus solves coil 9 and coil panel 10, coil panel 10 and motor shaft 1 displacement each other and loosening problem when being subject to axial vibrations and impacting.
Due to fuel gas shooting nail device in use, need after gas explosion, fast to ventilation in cavity 35 with stir, to need motor to run immediately, and the outer ring of now back-up ring 4 contacts with motor magnetite seat 6, frictional force can cause the poor starting of motor, therefore needs back-up ring 4 to be separated as early as possible with motor magnetite seat 6.In the present embodiment, bearing indoor location Compress Spring 7 residing for clutch shaft bearing 5, when fuel gas shooting nail device uses, play cushioning effect to the axial force produced after gas explosion, the thrust that simultaneously can also produce B direction is separated to promote back-up ring 4 with motor magnetite seat 6.
In the actual use of the present embodiment, although the interaction energy of Compress Spring 7 makes motor be subject to axial force back-up ring 4 and magnetite seat 6 collision rift quick separating, because motor shaft 1 use procedure high speed rotates, back-up ring 4 and magnetite seat 6 have friction, use can make magnetite seat 6 be ground dented by back-up ring 4 frequently, cause motor shaft 1 to be shifted, therefore this example is preferably at back-up ring 4 and magnetite seat 6 appearance hard chrome plating, and is coated with high temperature resistant luboil fat.
In addition, in the present embodiment, the distance of back-up ring 4 (being specially outer ring) to motor magnetite seat 6 end face is greater than to the distance of carbon brush fixed axis 12 bottom commutator 14, add the surperficial hard chrome process of back-up ring 4 and magnetite seat 6, thus ensure that motor shaft 1 is when being subject to axial impact force, commutator 14 is not damaged.
To sum up, the fuel gas shooting nail device of the present embodiment and the advantage of motor as follows:
1, the rear end of the anti-knock shock resistance force motor motor shaft of the present embodiment devises boss, coil panel devises stop tooth, adopt alignment pin to fix between locating snap ring with motor shaft to weld again, thus when solving motor by axial impact force, the displacement of motor associated components and loosening problem;
Laid Compress Spring in the bearing chamber of 2, the anti-knock shock resistance force motor of the present embodiment, and bearing can be free to slide, thus solve fuel gas shooting nail device in use to the axial impact force of motor, protection internal structure of motor.
3, the back-up ring of the anti-knock shock resistance force motor of the present embodiment and motor shaft loose fit, and on back-up ring, increase locating snap ring, alignment pin, ensure back-up ring and motor magnetite seat and bearing keeping parallelism state, when motor shaft is by jerk, the power that back-up ring acts on bearing and motor magnetite seat is horizontal homogeneous, to increase the whole service life of motor.
4, the back-up ring of the anti-knock shock resistance force motor of the present embodiment and magnetite seating face adopt hard chrome plating process, and be coated with high temperature-resistant grease, avoid, because described back-up ring and the described magnetite seat magnetite seat depression etc. frequently touching, in spin friction process causes the displacement of motor shaft, damaging carbon brush for electric machine.
Laid Compress Spring in the bearing chamber of 5, the anti-knock shock resistance force motor of the present embodiment, motor can Rapid reset after fuel gas shooting nail device nailing, thus solves after fuel gas shooting nail device goes out iron nail, the quick starting problem of motor.Also solve fuel gas shooting nail device in addition after injection iron nail, the waste gas in cavity is discharged and oxygen sucks problem.
6, the commutator afterbody of the anti-knock shock resistance force motor of the present embodiment fills an insulation spacer and adds a metallic gasket again, and metallic gasket and motor shaft is welded together, commutator and motor shaft loose shift when being given a shock impulsive force to avoid motor shaft.
It should be noted that, although the anti-knock shock resistance force motor in the present embodiment is example for fuel gas shooting nail device, but it will be appreciated by those skilled in the art that this anti-knock shock resistance force motor also may be used for other suitable field, be not limited to fuel gas shooting nail device.
Above-described embodiment, just the present invention's more preferably embodiment is several, and the usual change that those skilled in the art carries out within the scope of technical solution of the present invention and replacing all should be included in protection scope of the present invention.
