Claims
- 1. A structure of bonding parts comprising:
a first member formed with a first hole having a tapered portion; a second member formed with a second hole; and a first tapered barrel embedded in said first hole, said first tapered barrel having a tapered portion, wherein said first and second members are fastened with a bolt inserted through said first and second holes arranged in alignment with each other, and the tapered portion of said first hole has a height substantially equal to a length of the tapered portion of said first tapered barrel.
- 2. A structure of bonding parts according to claim 1, wherein:
said first member is a soft member; and said first tapered barrel is formed of a material harder than said first member.
- 3. A structure of bonding parts according to claim 1, wherein:
said first member is a brittle member; and said first tapered barrel is formed of a material softer than said first member.
- 4. A structure of bonding parts according to claim 1, wherein:
said second hole is formed with a tapered portion; and said coupling structure further comprises a second tapered barrel embedded in said second hole, said second tapered barrel having a tapered portion.
- 5. A structure of bonding parts according to claim 4, wherein:
said first tapered barrel has a female thread; said second tapered barrel has a throughhole; and said first and second members are fastened together by a bolt inserted through said through hole and screwed into said female thread.
- 6. A structure of bonding parts according to claim 4, wherein:
said first tapered barrel has a stud bolt; said second tapered barrel has a throughhole; and said first and second members are fastened together by the stud bolt inserted through said throughhole and screwed into a nut.
- 7. A structure of bonding parts according to claim 4, wherein:
the tapered portion of said second hole has a height substantially equal to a length of the tapered portion of said second tapered barrel.
- 8. A structure of bonding parts according to claim 1, wherein:
said first tapered barrel has a female thread; said second hole is a throughhole; and said first and second members are fastened together by a bolt inserted through said throughhole and screwed into said female thread.
- 9. A structure of bonding parts according to claim 1, wherein:
said first tapered barrel has a throughhole; said second hole is formed with a female thread; and said first and second members are fastened together by a bolt inserted through said throughhole and screwed into said female thread.
- 10. A method of bonding parts comprising the steps of:
forming a first member with a first hole having a tapered portion; embedding a first tapered barrel having a tapered portion into said first hole; forming a second member with a hole extending there through; arranging said first and second members such that said first hole is in alignment with said second hole; and fastening said first and second members together by inserting a bolt through said first second holes, wherein the tapered portion of said first hole has a height substantially equal to a length of the tapered portion of said first tapered barrel.
- 11. A method of bonding parts according to claim 10, wherein:
said first member and said second member are coupled by said first tapered barrel formed of a material harder than said first member.
- 12. A method of bonding parts according to claim 10, wherein:
said first member and said second member are coupled by said first tapered barrel formed of a material softer than said first member.
- 13. A structure of bonding parts comprising:
a first member having an inner surface in a first tapered shape; a first barrel formed of a material harder than said first member and having a second tapered shape which matches said first tapered shape; a second member having an inner surface defining a first hole opposite to said first barrel, and a surface surrounding said inner surface in internal contact with said first barrel formed of a material harder than said first member; a male thread inserted into said first hole; and a female thread engaged with said male thread.
- 14. A structure of bonding parts according to claim 13, further comprising:
a second barrel made of a material harder than said second member, and having an outer surface in a third tapered shape and said female thread formed on an inner surface thereof, wherein said first hole has a surface in a fourth tapered shape which matches said second barrel; and said second barrel has a contact face at one end thereof.
- 15. A structure of bonding parts according to claim 13, wherein:
said second member is harder than said first member.
- 16. A structure of bonding parts comprising:
a first member having an inner surface in a first tapered shape; a first barrel formed of a material softer than said first member and having a second tapered shape which matches said first tapered shape; a second member having an inner surface defining a first hole opposite to said first barrel, and a surface surrounding said inner surface in internal contact with said first barrel formed of a material softer than said first member; a male thread inserted into said first hole; and a female thread engaged with said male thread.
- 17. A structure of bonding parts according to claim 16, further comprising:
a second barrel formed of a material softer than said second member, and having an outer surface formed in a third tapered shape and said female thread formed on an inner surface, said first hole having a surface in a fourth tapered shape which matches said second barrel, wherein said second barrel has a contact face at one end thereof.
- 18. A structure of bonding parts according to claim 16, wherein:
said second member is more brittle than said first member.
- 19. A method of coupling a first member and a second member together, comprising the steps of:
fitting a first barrel having a second tapered shape into an inner surface of said first member formed in a first tapered shape, said first barrel being harder than said first member; positioning said second member having a peripheral surface formed of a material harder than said first member around a screw insertion hole, and said first member such that said first barrel opposes said screw insertion hole; inserting a screw into said screw insertion hole; and fastening said screw such that said first tapered barrel comes in internal contact with said peripheral surface to couple said first member and said second member together.
- 20. A method of coupling a first member and a second member together, comprising the steps of:
fitting a first barrel having a second tapered shape into an inner surface of said first member formed in a first tapered shape, said first barrel being softer than said first member; positioning said second member having a peripheral surface formed of a material softer than said first member around a screw insertion hole, and said first member such that said first barrel opposes said screw insertion hole; inserting a screw into said screw insertion hole; and fastening said screw such that said first tapered barrel comes in internal contact with said peripheral surface to couple said first member and said second member together.
