Multiple grooves 40, and the outside of the nut 38 be equipped with multiple protrusions 42 for separating along peripheral direction to the number groove
40 combine, so that the nut 38 and the rotor 24 are firmly combined.Furthermore the inside of the nut 38 has spiral helicine internal channel 44
To accommodate ball (not shown).The magnet 26 is looped around 24 outside of rotor.It can by the galvanomagnetic-effect that the stator 22 generates
Rotate together the rotor 24 with the nut 38.
The screw rod 20 has the inner end 46 and outer end 48 along the longitudinal subdivision, which passes through the nut 38 and hold
It is contained in the perforation 28 of the rotor 24, which stretches out in 32 outside of second end of the rotor 24.The bar diameter of the screw rod 20 is small
In the aperture of the perforation 28, and the outside of the screw rod 20 has spiral helicine outer channel 50, the outer channel 50 and the nut 38
Internal channel 44 it is opposite so that the ball in the nut 38 can be rolled in the outer channel 50.Thus, when the rotor 24 rotation,
The nut 38 rotated together with the rotor 24 will not be displaced, so that the screw rod 20 can be by driving and along this longitudinally opposed turn
Son 24 is mobile.
In the present embodiment, the ontology 14 have a front end 52, the front end 52 have one opening 53, the opening 53 with should
Room 15 inside ontology 14 is connected to.When the screw rod 20 is moved forward along the longitudinally opposed rotor 24, the screw rod 20
Outer end 48 can stretch out the front end 52 of the ontology 14 via the opening 53 (see Fig. 6).Furthermore the outer end 48 of the screw rod 20 combines one to go out
Power axis fixing plate 54, in the present embodiment, the outer end 48 of the screw rod 20 have a combined hole 56, pass through by a connection piece 58
The fixed plate 54 and locking the combined hole 56 combines the fixed plate 54 with the outer end 48 of the screw rod 20.In addition, the fixed plate 54
It is combined with the slide 16 by connector (such as screw) 60, so that the screw rod 20 is along longitudinally opposed 24 front and back of rotor
When mobile, the fixed plate 54 and the slide 16 longitudinally reciprocal can be moved along this together with the screw rod 20.
The motor mould group 10 further include one can elastic telescopic protective jacket 62.In the present embodiment, the opening of the ontology 14
One storage ring 64 of installation in 53, there is an axis hole 66 to be passed through with providing the screw rod 20 in the center of the storage ring 64, and the storage ring
64 outer end is equipped with a recess portion 68 to provide the protective jacket 62 receiving.In the present embodiment, which includes that diameter is different
Multiple cylinders 70, which can be made of metal material and mutually fitting links together to constitute and one stretch with elasticity
The multi-section type body of exhibition, and there is the body medium pore 72 to be passed through with providing the screw rod 20.Diameter is maximum in the protective jacket 62
Cylinder 70 be resisted against the storage ring 64 recess portion 68 inner wall, and the smallest cylinder 70 of diameter is resisted against the face of the fixed plate 54
To the end face of the front end 52, as shown in Figure 1.When the screw rod 20 is moved forward and backward along the longitudinally opposed rotor 24, the protection
Set 62 can be with stretching, extension or contraction.As shown in Figure 6, Figure 7, when the screw rod 20 is moved forward with respect to the rotor 24, the screw rod
20 outer end 48 can stretch out 52 1 sections of the front end preset length of the ontology 14, and the protective jacket 62 can utilize the elastic reaction of spring
Automatically it is extended into a long cylinder that 20 extension of screw rod is completely covered, so that 20 part of screw rod of the position in 14 outside of ontology
With dust-proof effect.Other direction, when the screw rod 20 is moved backward with respect to the rotor 24, the outer end 48 of the screw rod 20 can be protruded into
(see Fig. 1) in the opening 53 of the ontology 14, and the protective jacket 62 can be compressed and be become the short circle of a truncated cone shape by the fixed plate 54
Cylinder is to be accommodated in the storage ring 64.
As described above, 20 system of screw rod is threaded through the rotor 24 of the motor 18 in the motor mould group 10 of the utility model
It is interior and can be driven by the rotor 24 and be moved forward and backward along the longitudinally opposed rotor 24.Whereby, the motor mould of the utility model
Group 10 can more simplify the construction of motor mould group 10 other than it can be omitted the use of known shaft coupling.Specifically, when this
When 18 non-actuation of motor, the major part of the screw rod 20 is accommodated in the rotor 24 of the motor 18, thus, the motor mould can be reduced
The longitudinal length of group 10, and then reduce the volume of the electric cylinder 12.Furthermore when the motor 18 running, which will not be by
Rotation is driven, but the directly opposite rotor 24 is moved forward and backward to drive the sliding block 16 for linear motion in the rotor 24, is made
It obtains the screw rod 20 and is not required to the linear motion for being converted to the sliding block 16 via the connection of other elements again, can reach and simplify the horse
Up to mould group 10 structure and improve the application range and task performance of the motor mould group 10.In addition, when the screw rod 20 is with respect to this turn
When son 24 moves forward and stretches out the front end 52 of the ontology 14, which can stretch automatically and the screw rod 20 is completely covered
Exposed parts, so that the screw rod 20 has the effect of dust-proof and anti-aqueous vapor.
Aforementioned is to be described with regard to one specific embodiment of the utility model, and can do according to the design feature of the utility model more
Kind variation or modification are apprehensible.Therefore for being familiar with the obvious replacement and modification that this those skilled in the art can make, will be incorporated into
In the scope of the patents that the utility model is advocated.
