Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing will the present invention is described in more detail.
With reference to the accompanying drawings 1, make a clamping device that is used for the small-bore optical mirror slip of clamping of the present invention.
This instrument comprises a control handle 6, control handle 6 adopts metal or engineering plastics (for example teflon) to process, axis direction processing is portalled, this bore dia should be slightly larger than the thin end of piston and have the external thread diameter that cooperates with described nut 7, and the handle sharp processing becomes handwheel shape or sphere to hold handle with the handled easily person.
Also comprise a sleeve 1, this sleeve 1 adopts metal or engineering plastics (for example teflon) to be processed into the tube with a through hole, sleeve 1 inner chamber is stepped, center section with respect to sleeve 1 inner chamber, the inner chamber maximum of sleeve 1 latter end part, its top inner chamber minimum has internal thread 8 on the chamber wall of intermediate cavity; The length of the diameter of inner chamber and inner chamber each several part, those skilled in the art can design according to actual needs and implement.Sleeve 1 top inner chamber and lower lumen chamber wall want finishing to guarantee lower surfaceness, from practicality and processing cost angle, and suggestion surface roughness value R
a=0.8, the intermediate cavity of sleeve 1 processes internal thread 8, sleeve 1 outer wall can also process travers, with the handled easily person sleeve of better holding with a firm grip, process ring groove on the end face of the bottom port of this sleeve 1 placing first O-ring seal 3, the degree of depth of groove is put into first O-ring seal 3 and is exposed end face 1～2mm relatively behind the groove and be advisable;
One piston 2, these piston 2 bodies adopt metal or engineering plastics (for example common duralumin), be processed into the thin head of an end, the multidiameter that the afterbody that one end is thick is formed, a thin end has the external thread that cooperates with nut 7, a thick end has 2 continuous annular projections along the circumferencial direction of axle, wherein the matching relationship of the intracavity diameter of the diameter of latter end annular projection and sleeve 1 latter end part is for being slidingly matched, around the outer wall of this latter end annular projection first groove is set, described first groove is embedded in second O-ring seal 4; The diameter of second annular projection is littler than the diameter of latter end annular projection, has external thread 9 on the outer wall of this second annular projection, and internal thread 8 is identical with external thread 9 thread parameters; The end that piston only is thin penetrates and passes sleeve 1 top inner chamber, and the external thread that this thin end has is fixed together by described nut 7 and described control handle 6, drives described piston 2 and moves together, finish after the assembling state as shown in Figure 2;
Piston only will carry out finishing to guarantee lower surfaceness, suggestion surface roughness value R
a=0.8.
Can also on the outer wall of the afterbody latter end annular projection of piston 2 bodies, second groove be set and be embedded in the 3rd O-ring seal 5 at second groove;
First O-ring seal 3, second O-ring seal 4 and the 3rd O-ring seal 5 are the standard components that can buy on market, and the O-ring seal of for example selecting for use is that the Chinese rises the O-ring seal that sealing science and technology is produced; Described second O-ring seal 4, the 3rd O-ring seal 5 are fixed in the piston crown ring groove, follow piston and slide along sleeve lining; For prevent that O-ring seal from rolling when piston moves, used O-ring seal 4, the O-ring seal 5 of present embodiment selected the star O-ring seal for use; Piston movement speed is not under the very fast situation, can adopt O-ring seals yet.
During real work, treat that clipped lens 10 contacts with first O-ring seal 3, the operator grasps control handle drives piston and moves upward, piston motion is when contacting with bush whorl, the operator clockwise rotates control handle and pins piston position, therefore 10 on piston end surface and eyeglass form a reliable depression, thereby hold eyeglass 10.The operator rotates counterclockwise control handle after eyeglass 10 is moved to the relevant position, promotes piston simultaneously and moves downward, and above-mentioned depression disappears, and eyeglass 10 breaks away from clamping device.
