Embodiment
Referring to Fig. 1-5, a kind of optical lens aligning device, comprises turntable, is fixedly installed on the base 2 on turntable and is arranged on the adjustable plate 3 on base 2; Adjustable plate 3 centers are provided with camera lens installation place; On base 2, be provided with some through holes, base 2 is fixed on turntable by dog screw 4; Through-hole diameter is greater than the diameter of bolt, reserves enough positions and adjusts surplus; Adjustable plate 3 is arranged on base 2 by adjusting bolt 5, between adjustable plate 3 and the surface of contact of base 2, is provided with pressure spring; Adjustable plate 3 is curvature circumference convex surface with base 2 surface of contact; Base 2 is circular arc concave surface with adjustable plate 3 surface of contact; Adjusting bolt 5 comprises screw rod and the upper and lower nut for adjusting screw(rod) length.
Referring to Fig. 1, the present embodiment is the schematic diagram of the aligning equipment of a kind of optical lens on turntable, and camera lens is fixed on interface conversion plate, and interface conversion plate is fixed on adjustable plate, and camera lens is constant by interface conversion plate and location, adjustable plate position.
1) ginseng Fig. 2, is first fixed on base the screw loose unloading on turntable, and base can move horizontally on turntable, measures the offset of camera lens, and the offset that makes horizontal translation changes in a little scope;
2) ginseng Fig. 3, the nut loose unloading below adjustable plate bolt, can move and free inclination by the vertical direction adjustable plate;
3) ginseng Fig. 4, according to the difference of misalignment measurement value correspondence position, the top nut of respective bolt on rotation adjustable plate, the length d of the bolt between variation adjustable plate and base
n(n>=3), the spring between base and adjustable plate is at the pretightning force F of bolt
pretightning forcegravity G with adjustable plate
gravitythe lower reacting force N that forms of effect
f, and adjustable plate bottom convex surface is tangent with base concave surface, forms anchorage force T, four kinds of power formation mobile equilibrium, as shown in Figure 4.
4) ginseng Fig. 5, on adjustable plate, n bolt, just forms n(n >=3) individual equilibrium point, n equilibrium point determined a planimetric position, and location, the planimetric position of adjustable plate is motionless, and mechanical balance mechanics formula is as shown in Equation 1;
