Second group of frame is additionally provided with the fixed cylinder that states, and is connected with for driving described second group between described fixed frame and first group of frame
The drive component of frame back and forth movement in the fixed cylinder, the drive component includes the ball screw through second group of frame, institute
The ball screw that states is provided with the feed screw nut that can drive second group of frame motion when which rotates.
A kind of structure of ball screw camera lens as 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 in the top of cushion block.
A kind of structure of described ball screw camera lens as 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
Two positioning in the holes.
A kind of structure of described ball screw camera lens as above, it is characterised in that：Described the first location hole and
Second positioning in the hole is respectively equipped with bearing.
A kind of structure of described ball screw camera lens as above, it is characterised in that：The fixed frame and described
The guide shaft being additionally provided between a group frame for being oriented to second group of frame.
A kind of structure of described ball screw camera lens as above, it is characterised in that：The cushion block is semicircle knot
Structure.
Compared with prior art, a kind of structure of ball screw camera lens of the present invention, has reached following effect：
1st, the action piece of the present invention is that group's frame, feed screw nut, ball screw, the weight of action piece greatly reduces, required
Driving force is reduced, and interface pressure is reduced.
2nd, the drive component of the present invention is ball screw and feed screw nut, and the hardness of both is very high, and precision is also non-
Chang Gao, then its transmission accuracy also greatly improve than existing structure accordingly, hardness height then improve big metal shot existing structure
The problem of endurance life.
3rd, the structure of the present invention changes anyway, and the fixed frame of ball screw need not bear the pressure of relative motion, hold
Received is static pressure, without relative motion, does not wear and tear, reduces noise during lens zoom, increase the camera lens life-span, reduces camera lens
Parts and the weight of camera lens.
