Abstract
The utility model belong to the technology of airplane assembly, relates to a bushing extractor for taking a bushing of a tool positioning member out of an installation hole. The bushing extractor is characterized in that the extractor comprises a pin [1] and a pressing sleeve [2]; the pin [1] is a cylindrical shaft; a convex shoulder [1a] is arranged at the upper end of the pin [1]; the pressing sleeve [2] is a sleeve with a multi-step shaft shape. The bushing extractor has the advantages that the bushing extractor can prevent the positioning hole of the tool positioning member from being damaged during taking out the bushing, avoids adding the repair procedures of expanding the positioning hole and the like, and ensures the positioning accuracy and quality of the product.
Description
Technical field
The utility model belongs to the aircraft mounting technology, relates to a kind of bush extractor that lining on the tool locating part is taken out from installing hole.
Background technology
Lining is a kind of part commonly used in the aircraft tool locating part, through using for a long time, usually has the lining internal diameter overproof, and the phenomenon that can not satisfy positioning requirements occurs, and needs overproof lining to be taken out the lining that more renews.Mostly the method for taking out lining now is directly lining to be knocked with hammer; Easy like this damage is caused in the tool locating hole; Influence the precision of locating hole; Need position the repair procedure such as reaming in hole, not only increase processing cost but also influenced frock quality and positioning accuracy, and then influence product orientation precision and quality.
Summary of the invention
The purpose of the utility model is: a kind of bush extractor that can prevent to damage tool locating part locating hole is provided, to avoid increasing the repair procedure such as reaming of locating hole, guarantees the positioning accuracy and the quality of product.
The technical scheme of the utility model is: a kind of bush extractor; It is characterized in that; It is made up of pin 1 and gland 2; Pin 1 is a cylinder axis, and the endoporus matched in clearance of lining 3 to be removed on the diameter of this cylinder axis and the tool locating part 4 has the convex shoulder 1a of a diameter greater than pin 1 diameter in the upper end of pin 1; Gland 2 is the sleeves with step axle profile; The external diameter of the epimere 2a of gland 2 is greater than the external diameter of the hypomere 2b of gland 2; The external diameter of gland 2 hypomere 2b is less than the external diameter of lining 3 to be removed, and the diameter of bore of gland 2 hypomere 2b equals the internal diameter of lining 3 to be removed, and the endoporus of gland 2 epimere 2a is a stepped hole; The aperture of the last sector hole of this stepped hole is greater than the external diameter of pin 1 convex shoulder 1a, and the endoporus of the following sector hole of this stepped hole and gland 2 hypomere 2b is same hole; In the endoporus of the cylinder axis insertion gland 2 hypomere 2b of pin 1 and the endoporus of lining to be removed 3; The step end face of lower surface and gland 2 epimere 2a endoporus of 1 convex shoulder 1a of pinning is fitted; The pin upper surface of 1 convex shoulder 1a flushes with the upper surface of gland 2, and the length of gland 2 hypomere 2b is greater than the length of lining 3 to be removed.
The utility model has the advantages that: can prevent to damage the locating hole of tool locating part when taking out lining, avoid increasing the repair procedure such as reaming of locating hole, guarantee the positioning accuracy and the quality of product.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Explain further details in the face of the utility model down.Referring to Fig. 1, a kind of bush extractor is characterized in that; It is made up of pin 1 and gland 2; Pin 1 is a cylinder axis, and the endoporus matched in clearance of lining 3 to be removed on the diameter of this cylinder axis and the tool locating part 4 has the convex shoulder 1a of a diameter greater than pin 1 diameter in the upper end of pin 1; Gland 2 is the sleeves with step axle profile; The external diameter of the epimere 2a of gland 2 is greater than the external diameter of the hypomere 2b of gland 2; The external diameter of gland 2 hypomere 2b is less than the external diameter of lining 3 to be removed, and the diameter of bore of gland 2 hypomere 2b equals the internal diameter of lining 3 to be removed, and the endoporus of gland 2 epimere 2a is a stepped hole; The aperture of the last sector hole of this stepped hole is greater than the external diameter of pin 1 convex shoulder 1a, and the endoporus of the following sector hole of this stepped hole and gland 2 hypomere 2b is same hole; In the endoporus of the cylinder axis insertion gland 2 hypomere 2b of pin 1 and the endoporus of lining to be removed 3; The step end face of lower surface and gland 2 epimere 2a endoporus of 1 convex shoulder 1a of pinning is fitted; The pin upper surface of 1 convex shoulder 1a flushes with the upper surface of gland 2, and the length of gland 2 hypomere 2b is greater than the length of lining 3 to be removed.
The method for using of the utility model is: in the endoporus of the 1 insertion gland 2 of at first will pinning; To pin then 1 insert lining 3 to be removed endoporus; The lower surface and lining to be removed 3 end faces of gland 2 are fitted, knock bush extractor with hammer, because location, the guiding function of pin 1 are arranged; Lining 3 to be removed is just by vertical taking-up, thereby avoided the damage to lining 3 installing holes on the tool locating part.
Embodiment 1: the external diameter of lining 3 to be removed is φ 15r6, and the internal diameter of lining 3 is φ 10H7, and the length of lining 3 is 10mm.The external diameter of pin 1 is φ 10r6.The external diameter of gland 2 is φ 13, and the internal diameter of gland 2 is φ 10H7, and length is 15mm.
Embodiment 2: the external diameter of lining 3 to be removed is φ 20r 6, and the internal diameter of lining 3 is φ 15H7, and the length of lining 3 is 15mm.The external diameter of pin 1 is φ 15r 6.The external diameter of gland 2 is φ 18, and the internal diameter of gland 2 is φ 15H7, and length is 20mm.
Embodiment 3: the external diameter of lining 3 to be removed is φ 10r6, and the internal diameter of lining 3 is φ 6H7, and the length of lining 3 is 10mm.The external diameter of pin 1 is φ 4r6.The external diameter of gland 2 is φ 8, and the internal diameter of gland 2 is φ 4H7, and length is 15mm.
