Second group of drive component of frame back and forth movement in fixed cylinder, the drive component includes the ball wire through second group of frame
Bar, described ball screw is provided with the feed screw nut that second group of frame motion can be driven when it is rotated.
A kind of device of ball screw camera lens as described above, it is characterised in that：It is provided with the side wall of the fixed frame
Cushion block, the fixed frame is provided with accommodating the holding tank of the feed screw nut above cushion block.
A kind of device of described ball screw camera lens as described above, it is characterised in that：First group of frame is provided with
First location hole, the cushion block is provided with the second location hole, and the two ends of the ball screw are respectively arranged on the first location hole and
In two location holes.
A kind of device of described ball screw camera lens as described above, it is characterised in that：Described the first location hole and
Bearing is respectively equipped with second location hole.
A kind of device of described ball screw camera lens as described above, it is characterised in that：The fixed frame and described
The guide shaft for being oriented to second group of frame is additionally provided between a group frame.
A kind of device of described ball screw camera lens as described above, it is characterised in that：The cushion block is tied for semicircle
Structure.
Compared with prior art, a kind of device of ball screw camera lens of the present utility model, has reached following effect：
1st, action piece of the present utility model is group's frame, feed screw nut, ball screw, and the weight of action piece greatly reduces, institute
The driving force for needing is reduced, and interface pressure is reduced.
2nd, drive component of the present utility model is ball screw and feed screw nut, and the hardness of both is very high, precision
Also very high, then its transmission accuracy is also greatly improved than existing structure accordingly, and hardness is high, improves big metal shot existing
The problem of structure endurance life.
3rd, structure of the present utility model changes anyway, and the fixed frame of ball screw is without the pressure for being subjected to relative motion
Power, what is born is static pressure, does not have relative motion, without abrasion, reduces noise during lens zoom, increases the camera lens life-span, is subtracted
The weight of few camera lens parts and camera lens.
