Abstract
The utility model belongs to Aircraft Tools manufacturing technology, relates to a kind of conveniently replaced location tapered sleeve.Location tapered sleeve is step cylinder; It is made up of spindle nose, groove, locating shaft and apical pore.The outside diameter size of spindle nose is greater than the outside diameter size of locating shaft; The outside diameter size of locating shaft is greater than the outside diameter size of groove; Taper hole is taper locating hole.The centerline hole of taper hole overlaps with the axial line of locating shaft.Apical pore is screwed hole; Apical pore overlaps with the centerline hole of taper hole; The internal diameter size of apical pore is less than the internal diameter size of taper hole.The utility model can facilitate, take out rapidly location tapered sleeve is installed from locating hole.Avoid frock to scrap new system; Avoid tool locating tapered sleeve installation site inconsistent overproof with the damage of tool locating part profile.
Description
Technical field
The utility model belongs to Aircraft Tools manufacturing technology, relates to a kind of conveniently replaced location tapered sleeve.
Background technology
After existing locating cone is enclosed within and installs in the locating hole of tool locating part, install owing to adopting interference fits between location tapered sleeve and mounting-positioning holes, in the time that product orientation aperture requires change, because without effective means, therefore take to scrap new system for small-sized tool locating part, take to destroy original lining installing hole and peripheral profiles thereof for large-scale tool locating part, take out after the tapered sleeve of original installation location the method that new system location tapered sleeve is installed after reaming again.
Take to scrap new system for small-sized tool locating part, need to spend manufacturing expense; Need the uncertain time to wait for the tool locating part of new system; Need the uncertain time in frock, to install the tool locating part of new system, the tool locating part of new system certainly exists with former tool locating part installation site inconsistent after installing.Take to install after reaming again the method for new system location tapered sleeve for large-scale tool locating part, certainly exist with former tool locating part installation site inconsistently, and tool locating part profile is damaged overproof.
Summary of the invention
The purpose of this utility model is: a kind of location tapered sleeve that can be convenient for changing in locating hole is provided.
The technical solution of the utility model is: a kind of location tapered sleeve that can be convenient for changing in locating hole, is characterized in that: location tapered sleeve is step cylinder; It is made up of spindle nose 1, groove 2, locating shaft 3 and apical pore 5.The outside diameter size of spindle nose 1 is greater than the outside diameter size of locating shaft 3; The outside diameter size of locating shaft 3 is greater than the outside diameter size of groove 2; Taper hole 4 is taper locating hole.The centerline hole of taper hole 4 overlaps with the axial line of locating shaft 3.Apical pore 5 is screwed hole; Apical pore 5 overlaps with the centerline hole of taper hole 4; The internal diameter size of apical pore 5 is less than the internal diameter size of taper hole 4.
The utility model has the advantages that: can facilitate, from locating hole, take out rapidly location tapered sleeve is installed.Avoid frock to scrap new system; Avoid tool locating tapered sleeve installation site inconsistent overproof with the damage of tool locating part profile.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below the utility model is described in further details.Referring to Fig. 1, a kind of location tapered sleeve that can be convenient for changing in locating hole, is characterized in that: location tapered sleeve is step cylinder; It is made up of spindle nose 1, groove 2, locating shaft 3 and apical pore 5.The outside diameter size of spindle nose 1 is greater than the outside diameter size of locating shaft 3; The outside diameter size of locating shaft 3 is greater than the outside diameter size of groove 2; Taper hole 4 is taper locating hole.The centerline hole of taper hole 4 overlaps with the axial line of locating shaft 3.Apical pore 5 is screwed hole; Apical pore 5 overlaps with the centerline hole of taper hole 4; The internal diameter size of apical pore 5 is less than the internal diameter size of taper hole 4.
Operation principle of the present utility model is:
Be screwed into common bolt of long stem in the apical pore 5 of location tapered sleeve, stop descendingly after the head of common bolt of long stem runs into locating hole bottom, in the time being rotated further common bolt of long stem, location tapered sleeve can upwards be pulled out locating hole along screw thread rotation direction is reverse.
