Technical problems to be solved provide one kind and possess compared with high workload efficiency, can bear high rotating speed, and make emulated robot arm
Speed and vigor can be compared with human arm a kind of straight line push-pull rod.
To achieve the above object, the present invention provides following technical solution：A kind of integration ball straight line push-pull rod, including sky
Spindle motor, ball nut, ball screw；Hollow shaft motor is internally provided with core motor axis, the egress end of core motor axis with
Ball nut is fixedly connected, and ball nut is internally provided with ball screw, and ball screw is done by ball with ball nut rotation
Push-and-pull movement, ball nut side is equipped with back pearl passage and playback is rolled in ball nut for ball.
Preferably, the egress end of the core motor axis is fixedly connected on ball nut and is directed to the larger mechanism of torsion
It can use and tapering screw thread is processed outside ball nut connecting pin, a plurality of groove for prolonging center line issue then be opened, with same belt transect
The fastening flare nut of taper is fastenedly connected end to compress core motor axis.
Preferably, be fixedly connected with ball nut can be with for the less mechanism of torsion for the egress end of the core motor axis
Horizontal and vertical groove is opened using ball nut connecting pin, clamping screw clamps core motor axis in openend.
Preferably, the core motor axis is by the size of expanded motor axis, and motor shaft is made hollow shaft.
Preferably, can be reduced to inside the core motor axis of hollow shaft motor when the ball screw retraction, so
The length of hollow shaft motor can be designed to greatest extent, it is as much as possible in finite length and diameter to be designed to hollow shaft electricity
The moment of torsion of the effective efficiency part increase motor of machine.
Compared with prior art, the beneficial effects of the invention are as follows：Hollow shaft motor is directly driven without middle other links
Energy consumption, ball screw can be reduced to when retraction inside the core motor axis of hollow shaft motor, and hollow shaft motor can design
Length to greatest extent, the effective efficiency part increase sky as much as possible for being designed to hollow shaft motor in finite length and diameter
The moment of torsion of spindle motor, can greatly improve efficiency, increase magnification, increase the energy density of unit volume, ball screw with
Ball nut has efficient and bears high-revolving characteristic, using ball-screw will not self-locking characteristic, it is same in more motors
When drive compound action joint can to fine motion make motor programming ignore thus greatly reducing operation program
Difficulty is programmed, for emulated robot arm, complete electric transmission can be close to the speed and vigor of the mankind.

Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
Please refer to Fig.1~4, in the embodiment of the present invention, a kind of integration ball straight line push-pull rod, including hollow shaft motor 1,
Ball nut 2, ball screw 3, are internally provided with core motor axis 7, core motor axis 7 is by increasing electricity in hollow shaft motor 1
Motor axis center is done sky by arbor size, and the egress end of core motor axis 7 is connected with ball nut 2, ball nut 2 with hollow turn
7 connecting pin of axis is equipped with taper thread, and opens a plurality of groove for prolonging center line issue, passes through the fastening flare nut with same taper
5 compression core motor axis 7 are secured to connect, can be horizontal and vertical using being opened in 2 connecting pin of ball nut when torsion is smaller
To groove, in openend, clamping screw 6 clamps core motor axis 7, and ball nut 2 is internally provided with ball screw 3, ball screw
