The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to maintenance, operation also comparatively stable full electric injection molding machine drive the linear electric motors of use.
The technical solution of the utility model is: a kind of direct-driven servo motor for full electric injection molding machine, comprise the stator and the rotor that match, stator is located at the rotor periphery, and rotor center arranges the ball wire rod member, and the feed screw nut in the ball wire rod member is fixedly connected with rotor one end.Adopt the ball wire rod member to replace traditional machine shaft, can realize rotatablely moving changes into accurate linear drives, makes motor be applied to preferably the drive system of injection machine.
Described ball wire rod member comprises ball, screw mandrel and feed screw nut, ball is located between screw mandrel and feed screw nut, and screw mandrel carries out rectilinear motion by ball, and its staring torque is less, use the creeping phenomenon that not there will be sliding and running on the equipment such as injection machine, can guarantee to realize accurate micro-feeding.
Described feed screw nut is fitted on the iron core endoporus of rotor, and rotor one end and feed screw nut's flange is fixedly connected with by screw, can effectively prevent dislocation.
Described rotor is the rare-earth permanent-magnetic synchronous rotor, and its starting current is little, and power factor is high, and rotating speed and load are irrelevant, and working stability, be convenient to accurate control.
Described stator two ends arrange respectively drive end bearing bracket and rear end cap, and feed screw nut's front end arranges fore bearing, and the feed screw nut rear end arranges rear bearing, and fore bearing is connected with drive end bearing bracket, and rear bearing is connected with rear end cap.
When these linear electric motors are applied to full electric injection molding machine, the end that screw mandrel is connected with injection machine is as the linear electric motors output, the linear electric motors operation principle is identical with conventional motors: after the linear electric motors starting, the rotation of rotor drives the feed screw nut and rotates, the feed screw nut rotatablely moves it to be converted into the rectilinear motion of screw mandrel by ball, thereby realizes the driving of injection machine.
The utility model, with respect to prior art, has following beneficial effect:
These linear electric motors adopt the connection of rare-earth permanent-magnetic synchronous rotor and ball wire rod member, will rotatablely move and be converted into linear drives, preferably by motor application in the drive system of injection machine, realize that high efficiency, high-precision driving control, guarantee accurate micro-feeding.
This structure of the linear motion actuator is simple, volume is little, lightweight, manufacture easy to maintenance, long service life, operating accuracy is high, the long-time reliable and stable work of energy, and environmental protection and energy saving, except can be applicable to full electric injection molding machine, also can be applicable in the equipment of other linear drives, therefore there is very large market potential.
These linear electric motors are applied on injection machine, environment-friendly advantage and production cost advantage with highly significant, experiment shows, with hydraulically powered injection machine, compare, its power consumption is the highest reduces 70%, and the pollution problem that does not exist hydraulic oil to reveal, saved the hydraulic oil cost in the hydraulic system, cooling water cost and system maintenance cost.
