The technical scheme that the utility model adopts is, a kind of full-automatic zoom lens assembly, comprise camera lens, and the object lens of camera lens rear end connection, junction at camera lens and object lens, be arranged with the motor base that matches with camera lens on the camera lens, described motor base is by upper, lower motor base is formed by fixedly connecting, upper motor base front is fixedly connected with motor, driving gear is housed on the motor drive shaft, outer face one edge of driving gear is fixedly connected with limited block, described upper motor base is left, right two outsides are arranged with respectively to grow motor base and grow the end xsect and are a trapezoidal left side, right two fixed blocks, a described left side, the place, inclined-plane that right two fixed blocks grow is a symmetrical left side that is fixedly connected with the induction limited block respectively, right two photoelectric limit switch; On the cylindrical of described motor base one side object lens, the follower gear of fixed installation one and driving gear engagement.
Have semicircle opening in the middle of below the described upper motor base, have the semicircle opening corresponding with upper motor base in the middle of above the motor base down.
The utility model has following beneficial effect compared to existing technology:
1, by the motor driven wheel is set, gear drive drives object lens and rotates, and has realized the full-automatic zoom of object lens;
2, measurement is convenient, fast, has improved work efficiency;
3, measured value has reduced degree of error closer to actual value.
