Stator 211 and be located in the rotor 212 in described stator 211, be arranged on described motor and with described rotor 212 and drive the screw rod 202 being connected, be arranged on screw rod 202 for controlling screw rod 202 along the axial elevating movement of rotor 212, and the function conversion and control assembly 300 of following rotor 212 to rotate at screw rod 202 when rotor 212 is axially elevated to arbitrary position, and be arranged between screw rod 202 and function conversion and control assembly 300 for limiting screw rod 202 and function conversion and control assembly 300 limit structure 400 in relative rotation.
In the present embodiment, the effect of rotor 212 is, for screw rod 202 provides power, wherein, rotor 212 is preferably tapped hollow rotor, and screw rod 202 is spirally connected with rotor 212, and, when rotor 212 rotates, screw rod 202 follows rotor 212 to rotate.
The effect of function conversion and control assembly 300 is, controls screw rod 202 along the axial elevating movement of rotor 212 and follows rotor 212 to rotatablely move, and switching between these two motion states.
The effect of limit structure 400 is, limits screw rod 202 and relatively rotates with function conversion and control assembly 300, that is to say, when screw rod 202 rotates, this function conversion and control assembly 300, under the effect of limit structure 400, is followed screw rod 202 and is rotated, and vice versa.
Shown in Fig. 6, Fig. 6 is the sectional view of the utility model the second embodiment's two degree-of-freedom motion device, and described function conversion and control assembly 300 comprises:
Be set on screw rod 202 for conversion and control screw rod 202 along the axial elevating movement of rotor 212, and at screw rod 202, when rotor 212 is axially elevated to arbitrary position, follow the function conversion block 310 of rotor 212 rotations.
Be set in outside described function conversion block 310 and be arranged on stator 211 and fix this function conversion block 310 and force screw rod 202 along the first electromagnet 320 of rotor 212 axial liftings for adsorbing.
And be arranged on the first electromagnet 320 tops, inner side and on rotor 212 end faces, make it follow at least one elastic force of rotor 212 rotation to hold structure 330 for described function conversion block 310 is held.
Described screw rod 202 is successively through described electromagnet 330, function conversion block 320, and be threaded with rotor 212, particularly, in the first electromagnet 320 central positions, offer circular hole 320a, in function conversion block 310 central positions, offer circular hole 310a, screw rod 202 passes circular hole 320a, circular hole 310a successively, and is screwed onto in rotor 212.
Shown in Fig. 7, Fig. 7 is the plan view of the utility model the second embodiment's two degree-of-freedom motion device, and described limit structure 400 comprises:
Be arranged on the limit sliding chutes 410 of screw rod 202 outer surfaces on axially, and be arranged on function conversion block 310 corresponding positions and embed the spacing preiection 420 in this limit sliding chutes 410, should be specifically on the inwall of circular hole 310a.Particularly, after function conversion block 310 is socketed on screw rod 202,420 of spacing preiections embed in this limit sliding chutes 210, realize this function conversion 310 and side direction, screw rod 202 are limited, and limit it with rotor 212 rotations.Certainly, the spacing fit system that is not limited to above-mentioned limit sliding chutes and spacing preiection that coordinates between screw rod 202 and function conversion block 310.
Described the first electromagnet 320 tops, inner side offer through hole 321, and this through hole 321 is preferably three, axially arranges respectively around screw rod 202, and so, corresponding described elastic force holds 330, structure and is arranged in this through hole 321.Particularly, described elastic force holds structure 330 and comprises: ecto-entad is successively set on steel ball 331, the spring 332 in described through hole 321, and set screw 333, wherein, steel ball 331 is for holding described function conversion block 310 at rotor 212 end faces, by elastic force, hold structure 330 and from three points, function conversion block 310 is held respectively, the frictional force between function conversion block 310 and rotor 212 end faces is increased.
