Abstract
The utility model discloses a kind of axle and can locate flexible direct driving motor, described direct driving motor comprises shell, the inwall of shell is provided with stator, hollow rotor is provided with in shell, the two ends of rotor are provided with bearing, the inwall of described rotor is provided with slide rail, is provided with ball screw in rotor, the nut of ball screw is provided with two keyways, described keyway can be free to slide along the slide rail of sleeve rotor inwall.In use, because axle can automatic telescopic, and motor is motionless to the utility model, can realize the action that a motor replaces two motors, avoids repeating motion and wastes electric energy, meets the requirement of environmental protection, and compact conformation, simple, easy to use.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of motor, particularly relates to a kind of axle and can locate flexible direct driving motor.
Background technology
Existing injection class machinery, such as injection molding machine, it is injected and feeds in raw material is by an injection cylinder and a default fluid motor-driven, or independently controlled by two motors, such as sky, sea, industry leaders Ningbo molding machine, Shen, Hangzhou reach manufacture, be all these two kinds of modes, wherein oil cylinder adds the type of drive more backwardness of hydraulic motor.And at present world advanced person Japanese Fa Nake, day essence machinery be also driven by two motors.
The injection of injection molding machine and reinforced be same screw rod, control respectively to keep straight on and rotated back two actions with two motors, too loaded down with trivial details in mechanical structure, and also injection and then retreats together with motor when reinforced, repeating motion causes the waste of electric energy, more brings the limitation of injection response speed.
Utility model content
Based on above problem, the purpose of this utility model is to provide one in use, and axle can automatic telescopic, and motor is motionless, can repeating motion be avoided and waste electric energy, meeting the requirement of environmental protection, and structure is simple, linear running response is fast, direct driving motor easy to use.
A kind of axle can locate flexible direct driving motor, described direct driving motor comprises shell, the two ends of shell are provided with stator, hollow rotor is provided with in shell, the surrounding of rotor is provided with bearing, the inwall of described rotor is provided with slide rail, is provided with ball screw in rotor, the nut of ball screw is provided with two keyways, described keyway can be free to slide along the slide rail of sleeve rotor inwall.
Preferably, described sleeve rotor the is built-in transportable ball-screw of slide block.
Preferably, motor is configured with cooling system, and cooling system is water-cooled.
The beneficial effects of the utility model: in use, because axle can automatic telescopic, and motor is motionless to the utility model, can avoid repeating motion and waste electric energy, meets the requirement of environmental protection, and structure is simple, and rectilinear motion response is fast, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of axle of the utility model can locate flexible direct driving motor;
Fig. 2 is the profile that a kind of axle of the utility model can locate flexible direct driving motor.
Number in the figure is described as follows: 1-shell, 2-stator, 3-rotor, 4-bearing, 5-slide rail, 6-ball screw, 7-nut, 8-keyway.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Fig. 1 and Fig. 2 is respectively structural representation and the profile that a kind of axle can locate flexible direct driving motor, described direct driving motor comprises shell 1, the inwall of shell 1 is provided with stator 2, hollow rotor 3 is provided with in shell 1, the surrounding of rotor 3 is provided with bearing 4, the inwall of described rotor 3 is provided with slide rail 5, is provided with ball screw 6 in rotor 3, the nut 7 of ball screw 6 is provided with two keyways 8, described keyway 8 can be free to slide along the slide rail 5 of sleeve rotor 3 inwall.Described sleeve rotor the is built-in transportable ball-screw of slide block, achieves the possibility of relative motion.The material of described shell 1 is aluminium alloy, and motor is configured with cooling system, and cooling system is water-cooled, achieves less volume and larger moment of torsion, and is removed by heat in time when being conducive to machine operation.
During utility model works, switch on power, rotor 3 starts to rotate, nut 7 rotates, when nut 1 forwards the rear portion of rotor 3 to, because screw top is bottom rotor 3 because the existence of key can only follow rotor 3, such motor shaft can only rotary motion, can not contract inward again, and when injection molding machine is injected time, motor inverted running, at this time because axle head is by the resistance from barrel, screw rod does not move ahead, and nut 7 moves ahead relatively, until arrive anterior, by clutch is fixing can not linear running again, then motor forward runs, at this time screw rod relative motion moves ahead, nut 7 is by the restriction of clutch, can only rotate can not rectilinear motion, going straight ahead during screw rod relative motion, when injection position arrives time, electric signal solenoidoperated cluthes are opened, motor continues to rotate, at this time nut 7 can the restriction cancellation of rectilinear motion, the end is expelled to due to screw rod front portion, so screw rod must be driven to rotate, rotate while retreat under the effect of reaction force again, complete a compound motion, until the end of back to, then motion is next time carried out.
In use, because axle can automatic telescopic, and motor is motionless to the utility model, can avoid repeating motion and waste electric energy, meets the requirement of environmental protection, and structure is simple, and rectilinear motion response is fast, easy to use.
Embodiment recited above is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that the common engineers and technicians in this area make the technical solution of the utility model and improvement, all should fall in protection range that claims of the present utility model determine.
