Abstract
The utility model discloses a kind of chemical milling template Special drill bushing, there is on drill bushing main body under main body and drill bushing, on drill bushing, under main body and drill bushing, main body is respectively equipped with coaxial guide hole I and II, and on drill bushing, main body comprises base I and boss, and boss is provided with annular bulbous recess; The spherical convex tendon of annular that under drill bushing, main body comprises base II and matches with annular bulbous recess; On drill bushing, main body is also furnished with the parcel matched with base I profile and overlaps I, and under drill bushing, main body is furnished with the parcel matched with base II profile and overlaps II.This Special drill bushing structure is simple; easy to operate, by wrapping up exposed drill bushing outside model, can effectively prevent metal drill bushing from directly contacting with milling part diaphragm and causing scuffing; and then making chemical milling template installation drill bushing become possibility, drill bushing is quick and easy for installation simultaneously.
Description
Technical field
The utility model relates to covering manufacture field, is specifically related to a kind of chemical milling template Special drill bushing, mainly in covering process, for the Special drill bushing of chemical milling template locating hole.
Background technology
By the restriction of processing conditions, present stage, China's Aviation Manufacturing Enterprises was when producing covering class Varying-thickness part, and main processing mode is chemistry milling (abbreviation milling).Milling is put in aggressive chemistry solvent by the part to be processed scribbling part diaphragm, do not have part meeting and the chemical solvent generation chemical reaction of diaphragm, make piece surface dissolving metal, and then reach the object of milling.Key one step before milling processing is coated with diaphragm and rules with chemical milling template.Current existing chemical milling template is scratched to prevent diaphragm surface; locating hole on model does not install metal drill bushing; but directly get out effective aperture; therefore in the production of milling part and use procedure; locating hole on model in use has wearing and tearing, and then affects the line precision of subsequent parts.
Utility model content
In order to solve the deficiencies in the prior art; the utility model provides a kind of chemical milling template Special drill bushing; this Special drill bushing structure is simple; easy to operate; by wrapping up exposed drill bushing outside model; effectively can prevent metal drill bushing from directly contacting with milling part diaphragm and causing scuffing, and then make chemical milling template installation drill bushing become possibility, drill bushing is quick and easy for installation simultaneously.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of chemical milling template Special drill bushing, to have on drill bushing main body under main body and drill bushing, and on drill bushing, under main body and drill bushing, main body is respectively equipped with coaxial guide hole I and II, and on drill bushing, main body comprises base I and boss, and boss is provided with annular bulbous recess; The spherical convex tendon of annular that under drill bushing, main body comprises base II and matches with annular bulbous recess; On drill bushing, main body is also furnished with the parcel matched with base I profile and overlaps I, and under drill bushing, main body is furnished with the parcel matched with base II profile and overlaps II.
Described chemical milling template Special drill bushing, described annular bulbous recess and the spherical convex tendon interference fit of annular.
Described chemical milling template Special drill bushing, the height of described boss and the thickness of chemical milling template match.
Described chemical milling template Special drill bushing, is also provided with boss II between described base I and boss, and the height of described boss II matches with the thickness of parcel cover I.
Described chemical milling template Special drill bushing, described parcel cover I and II is rubber parcel cover.
Described chemical milling template Special drill bushing, the aperture of described guide hole II is greater than the aperture of guide hole I.
The utility model has following beneficial effect;
A kind of chemical milling template Special drill bushing of the utility model; structure is simple; install convenient to operation; make chemical milling template that drill bushing is installed and become possibility; this drill bushing not only can prevent metal drill bushing from directly contacting with milling part diaphragm and causing scuffing; also reduce the wearing and tearing of chemical milling template locating hole, improve the line precision of milling part.
This drill bushing is by the interference fit of annular bulbous recess and the spherical convex tendon of annular simultaneously, makes this drill bushing easy for installation and fastening difficult drop-off, facilitates the use of chemical milling template.A kind of chemical milling template Special drill bushing of the utility model, can be widely used in the field of machining that aviation, boats and ships etc. relate to the installation of chemical milling template drill bushing.

Detailed description of the invention
As shown in Figure 1-2, a kind of chemical milling template Special drill bushing, to comprise on drill bushing main body 2 under main body 1 and drill bushing, and on drill bushing, under main body 1 and drill bushing, main body 2 has coaxial guide hole I 11 and II 21 respectively, and the aperture of guide hole II 21 is greater than the aperture of guide hole I 11.
On drill bushing, main body 1 comprises base I 12 and boss 13, and boss 13 is provided with annular bulbous recess 14; On drill bushing, main body 1 is furnished with the parcel matched with base I 12 profile and overlaps I 15.The height of boss 13 and the thickness of chemical milling template 3 match.Also be provided with boss II 16 between base I 12 and boss 13, the height of boss II 16 matches with the thickness of parcel cover I 15.
The spherical convex tendon 23 of annular that under drill bushing, main body 2 comprises base II 22 and matches with annular bulbous recess 14; Under drill bushing, main body is furnished with the parcel matched with base II 22 profile and overlaps II 24.Annular bulbous recess 14 and annular spherical convex tendon 23 interference fit.Parcel cover I 15 and II 24 is rubber parcel cover.
In a pre-installation, first main body on drill bushing 1 and parcel cover I 15 are combined, under drill bushing, main body 2 is combined with parcel cover II 24.During installation, main body 1 on drill bushing with parcel cover I 15 is inserted in the locating hole of chemical milling template 3, then chemical milling template 3 is turned, installation is with main body 2 under the drill bushing of parcel cover II 24, spherical for the annular of main body under drill bushing 2 convex tendon 23 is placed on the annular bulbous recess 14 of main body 1 on drill bushing, main body 2 under the drill bushing utilizing mallet to knock with parcel cover II 24, makes annular spherical convex tendon 23 enter in annular bulbous recess 14.
