Abstract
The utility model belongs to an aircraft tooling manufacturing technology and particularly relates to a positioning bushing capable of being replaced in a blind hole. In the positioning bushing capable of being replaced in the blind hole, the positioning bushing (1) consists of a working inner hole (2) matched with a product positioning aperture, a matched outer ring (3) and an ejection screw thread (4) communicated with the working inner hole (2); the working inner hole (2) is in a round shape or a polygonal shape; the matched outer ring (3) is a round working surface in an interference fit tolerance requirement; and the ejection screw thread (4) is a common screwed hole of which the diameter is less than or equal to the diameter of the working inner hole (2).
Description
Technical field
The utility model belongs to aircraft frock manufacturing technology, particularly relates to a kind of positioning adapter that can change in blind hole.
Background technique
After existing positioning adapter is installed in the blind hole of tool locating part, because adopting transition fit between positioning adapter and the installing and locating hole installs, when the product orientation aperture requires change, need change the tool locating part again, do not reuse existing tool locating part because there is effective means, therefore take scrap system for small-sized tool locating part, then take to destroy original lining mounting hole and peripheral profiles thereof for large-scale tool locating part, after taking out original installing and locating lining, the method for new system positioning adapter is installed after the reaming again.
Take to scrap new system for small-sized tool locating part, need the cost manufacturing expense; Need the uncertain time to wait for the tool locating part of new system; Need the uncertain time to install the tool locating part of new system in frock, the tool locating part of new system certainly exists with former tool locating part mounting point inconsistent after installing.Take to install after the reaming again the method for new system positioning adapter for large-scale tool locating part, certainly exist with former tool locating part mounting point inconsistently, and tool locating part profile is damaged overproof.
Summary of the invention
The purpose of this utility model is: a kind of positioning adapter that can be convenient for changing in blind hole is provided.
The technical solution of the utility model is:
A kind of positioning adapter that can in blind hole, change, positioning adapter 1 is by forming with work endoporus 2, the cooperation cylindrical 3 of product orientation aperture coupling and the screw thread 4 that ejects that communicates with work endoporus 2, work endoporus 2 is circle or polygonal endoporus, cooperating cylindrical 3 is the circular working surface of interference fit tolerance, ejects screw thread 4 is less than or equal to work endoporus 2 diameters for diameter regular screw threads hole.
The utility model has the advantages that:
The utility model can make things convenient for, take out rapidly the installing and locating lining from blind hole.Avoided frock to scrap new system; Avoided tool locating lining mounting point inconsistent overproof with the damage of tool locating part profile.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
When using the utility model, select and positioning adapter according to the product orientation aperture earlier with work endoporus 2 of its coupling, be inserted into the blind hole of tool locating part, after being used to complete, be screwed into ejecting in the screw thread 4 of positioning adapter 1 with common bolt of long stem, stop descendingly after the head of common bolt of long stem runs into the blind hole bottom, when being rotated further common bolt of long stem, positioning adapter 1 can upwards be pulled out blind hole along the screw thread rotation direction is reverse.
Claims (1)
1. the positioning adapter that can in blind hole, change, by with the work endoporus of product orientation aperture coupling, cooperate cylindrical to constitute, it is characterized in that described positioning adapter also comprises the screw thread that ejects that communicates with the work endoporus, the work endoporus is circle or polygonal endoporus, cooperating cylindrical is the circular working surface of interference fit tolerance, and ejecting screw thread is the regular screw threads hole that diameter is less than or equal to the work diameter of bore.The utility model can make things convenient for, take out rapidly the installing and locating lining from blind hole.Avoided frock to scrap new system; Avoided tool locating lining mounting point inconsistent overproof with the damage of tool locating part profile.
