Embodiment
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
With reference to figure 1, the said optical lens micromatic setting of the utility model comprises: lens drum 1, lens 2, lens mount 3 and driving lever 4.First by built-in for lens 2 and be fixed in lens drum 1.Then by lens 2 and lens drum 1 integrally activity be placed in lens mount 3.One end of driving lever 4 is passed lens mount 3 and inserts in lens drum 1, hold the other end of driving lever 4, by stirring driving lever 4 before and after optical axis direction, make driving lever 4 drive lens 2 of that one end in insertion lens drum 1 and lens drum 1 integrally in lens mount 3, move forward and backward along optical axis direction, realize drive lens 2 along the movable object of carrying out finely tuning of optical axis 6.
By built-in for lens 2 and to be fixed on the mode of lens drum 1 a lot, for the utility model, fixing mode adopts the sidewall of lens 2 to coat uniform bonding agent, is then fixed on the madial wall of lens drum 1.Adopt bonding agent fixing len 2, simple and fast, adhesive effect is good, and with low cost.
Be the full sectional view of Fig. 2 along A-A direction with reference to figure 3, Fig. 3.Because lens 2 have certain thickness, in order to make lens 2 in the correct location of the madial wall of lens drum 1, therefore on the madial wall of lens drum 1, be also provided with an annular groove 13.The internal diameter of annular groove 13 and the outer circumference diameter of lens 2 suitable, the circumferential edges thickness of groove width and lens 2 is suitable.Therefore, bonding agent is spread and after being fixed in groove 13, then lens 2 have just been fixed on the madial wall of lens drum 1 when the outer circumference of lens 2 being coated with.
Please continue to refer to Fig. 3, in order to insert driving lever 4, the sidewall of lens mount 3 offers a through hole 31, lens drum 1 offers a blind hole 11.One end of driving lever 4 is first through through hole 31, and then insert in blind hole 11, by holding the other end of driving lever 4 and repeatedly finely tune lens drum 1 before and after optical axis 6, because lens 2 have been fixed on lens drum 1, when lens drum 1 is finely tuned in lens mount 3 before and after optical axis 6, then lens 2 are also inevitable moves forward and backward along optical axis 6, thus achieves the object of fine setting lens 2.Can finely tune before and after optical axis 6 in lens mount 3 by drive lens cylinder 1 in order to driving lever 4 can be made, then driving lever 4 must be freely movable in through hole 31 and blind hole 11, that is, the internal diameter of through hole 31 and the internal diameter of blind hole 11 must meet the condition of the diameter being all greater than driving lever 4.
Further, driving lever 4 prioritizing selection is circle club shaped structure, because bar is drawn materials conveniently, and relatively good processing.
Here need to explain, why blind hole 11 can not be set to the reason of through hole.If blind hole 11 is set to through hole, then that one end that driving lever 4 inserts lens drum 1 will touch lens 2, because lens 2 belong to accurate expensive product, can cause great waste like this.
Please continue to refer to Fig. 3 and Fig. 4, lens mount 3 offers the inner arc of the side of through hole 31, be arranged to off-centre operation arcuation.Outer circumference due to lens drum 1 is circular, and the inner side off-centre operation arcuation part of lens mount 3 is cut to 2 points mutually with the outer circumference of lens barrel 1, two such as, in Fig. 2 tangent point of contact B.Therefore, just there is certain gap d (see Fig. 2 and Fig. 3) in the eccentric arc part inside lens mount 3 and the outer circumference of lens drum 1, the purpose of design of this gap d has two: the first, in the process of driving lever 4 drive lens cylinder 1 fine setting before and after optical axis 6 in lens mount 3, the friction between the outer circumference of lens drum 1 and the inside circumference of lens mount 3 can be reduced, make the fine setting of lens 2 more smooth and easy; The second, when after the fine setting completing lens 2, after lens 2 accurately adjustment predeterminated position in the optical path, need with screw 5, lens drum 1 to be locked on lens mount 3.Therefore, the object of gap d design is conducive to screw 5 and locks, and increases the coupling mechanism force between lens mount 3 and lens drum 1.
Please continue to refer to Fig. 3, in order to lens drum 1 is locked on lens mount 3 with screw 5, need in the outer circumference being provided with eccentric arc of lens mount 3, arrange an elliptical hole 32 (see Fig. 1 and Fig. 3), simultaneously at the internal thread through hole 12 (see Fig. 1 and Fig. 3) that the setting of the inner side of lens drum 1 and screw 5 match.It should be noted that the design attitude of elliptical hole 32 and internal thread through hole 12 will avoid the position of lens 2 in lens drum 1, after being screwed into screwless 5, cause the infringement to lens 2.
With reference to figure 3 and Fig. 4, in the bottom of lens drum 1 inside circumference, be also placed with a baffle ring 7.The centre of baffle ring 7 is the manhole passed through for light source.The object arranging baffle ring 7 is, is finely tuning in the process of lens 2 along optical axis 6, prevents the outside of the bottom of lens 2 from touching the bottom of lens drum 1 inside circumference, causes the infringement to lens 2.
This optical lens micromatic setting, by lens are fixed in lens drum, then by lens together with lens drum together activity be placed in lens mount; Utilize the through hole of the sidewall of a driving lever scioptics seat, insert in lens drum, drive lens together with lens drum in lens mount along optical axis direction back and forth translation fine setting, until by lens adjustment to the position of presetting, finally with screw, lens are locked on lens mount, thus achieve the object of lens precise fine-adjustment; In addition, the inside circumference being inserted with driving lever of lens mount is arranged to eccentric shape, in the process that lens drum is finely tuned in lens mount before and after optical axis, frictional resistance between the lateral wall of lens drum and the madial wall of lens mount is less, therefore regulate lens drum more smooth and easy and laborsaving, reduce the labour intensity of assembly crewman, saved the time, also improved work efficiency.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
