Abstract
The utility model discloses a centering device for lens assembly, it includes two arc pieces along vertical axis symmetric distribution, and the arc piece includes: the first arc-shaped positioning concave part is arranged at the top of the arc-shaped part and consists of side walls with L-shaped sections, and the radius from the vertical inner wall of the first arc-shaped positioning concave part to the vertical axis is R1; the second arc-shaped positioning concave part is arranged at the lower part of the first arc-shaped positioning concave part arranged on the arc-shaped piece and is formed by the side wall with the L-shaped section, and the radius from the vertical inner wall of the second arc-shaped positioning concave part to the vertical axis is R2; a third arc-shaped positioning concave part which is arranged at the lower part of the second arc-shaped positioning concave part arranged on the arc-shaped piece and is formed by the side wall with the L-shaped section, wherein the radius from the vertical inner wall of the third arc-shaped positioning concave part to the vertical axis is R2; r1 < R2 < R3. The device can accomplish the centering operation of three lens fast, ensures that metal casing can embolia in one step, when improving the installation effectiveness, very big emergence of having avoided lens fish tail scheduling problem.
Description
Technical Field
The utility model belongs to the technical field of the lens assembly technique and specifically relates to a centering device for lens assembly is related to.
Background
The lens of current camera lens utilizes the hand (hold) lens to gather together to the centering is observed to the naked eye, and this kind of assembly mode has following drawback:
1. the error is large, the metal frame is often not placed in the metal frame, and the metal frame needs to be repeatedly placed for a plurality of times;
2. the dust is easy to fall off, so that the lens needs to be wiped again;
3. the lens is easy to scratch and break.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem, provide a centering device for lens assembly, it can effectual promotion work efficiency, also can avoid the lens to produce the problem that the fish tail collapses a mouthful and so on when once successfully accomplishing the lens assembly.
In order to solve the above technical problem, the utility model discloses an embodiment provides a centering device for lens assembly, and it includes: two arcs symmetrically distributed along a vertical axis, the arcs comprising:
the first arc-shaped positioning concave part is arranged at the top of the arc-shaped part and consists of side walls with L-shaped sections, and the radius from the vertical inner wall of the first arc-shaped positioning concave part to the vertical axis is R1;
the second arc-shaped positioning concave part is arranged at the lower part of the first arc-shaped positioning concave part arranged on the arc-shaped piece and is formed by side walls with L-shaped sections, and the radius from the vertical inner wall of the second arc-shaped positioning concave part to the vertical axis is R2;
a third arc-shaped positioning concave part which is arranged at the lower part of the second arc-shaped positioning concave part arranged on the arc-shaped piece and is formed by the side wall with the L-shaped section, wherein the radius from the vertical inner wall of the third arc-shaped positioning concave part to the vertical axis is R2;
wherein R1 < R2 < R3.
Further, the arc-shaped piece is integrally formed.
The utility model discloses following beneficial effect has: the device can accomplish the centering operation of three lens fast, ensures that metal casing can embolia in one step, when improving the installation effectiveness, very big emergence of having avoided lens fish tail scheduling problem.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the following embodiments.
Embodiments of the present invention provide a centering device for lens assembly, see fig. 1-2, which includes: two arc-shaped pieces 1 are symmetrically distributed along the vertical axis O and have three arc-shaped positioning concave parts which are gradually reduced in diameter from bottom to top.
Specifically, referring to fig. 2, the arc includes: set up in arc piece top and by the first arc location concave part 10 that is the lateral wall of L type cross-section and constitutes, the radius of the vertical inner wall to the vertical axis of first arc location concave part is R1, and first arc location concave part is used for fixing a position first piece lens, and set up in the arc piece and establish first arc location concave part lower part and by second arc location concave part 11 that the lateral wall of L type cross-section constitutes then be used for fixing a position second piece lens, the radius of the vertical inner wall to the vertical axis of second arc location concave part is R2, set up in the arc piece and establish second arc location concave part lower part and by third arc location concave part 12 that the lateral wall of L type cross-section constitutes then be used for fixing a position third piece lens, the radius of the vertical inner wall to the vertical axis of third arc location concave part is R2, wherein, R1 < R2 < R3.
The arc-shaped pieces can be integrally formed, and because the two arc-shaped pieces are of a common circle structure, after the third lens at the bottom is abutted by the third arc-shaped positioning concave parts of the two arc-shaped pieces, the second lens and the first lens which are positioned above the third lens can quickly complete the state of being coaxial with the third lens at the bottom under the positioning effect of the second arc-shaped positioning concave part and the first arc-shaped positioning concave part, and the assembling work of the lenses can be completed by sleeving the outer shell at the moment.
Protective coatings can be arranged on the inner side wall of the arc-shaped part, and the protective coatings can be polyfluorinated compound coatings and rubber coatings.
It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
