本考案は取付部材、例えばキャップを被取付部材、例えばエンジンのクランク 軸を回転可能に保持するコネクティングロッドに固定する取付ボルトに関する。 更に詳しくは締りばめの機能を有する取付ボルトに関するものである。 The present invention relates to a mounting bolt for fixing a mounting member such as a cap to a mounted member such as a connecting rod that rotatably holds a crankshaft of an engine. More specifically, it relates to a mounting bolt having an interference fit function.
【０００２】[0002]
この種の取付ボルトとして、基端に設けられた頭部と、コネクティングロッド に形成された通孔及びキャップに形成された透孔に挿通される軸部と、先端に形 成されナットが螺合される雄ねじ部とを有し、熱間鍛造により形成されたものが 知られている。このボルトの頭部以外の外周面は旋盤加工や研摩加工の機械加工 が施され、軸部は段付に形成され、軸部の最大外径部が通孔及び透孔の内径と略 同一に仕上げられる。この同一仕上げはコネクティングロッドの半円状凹部と、 キャップの半円状凹部を向い合せてこれらを一体化したときに真円度を確保する ために行われる。 As a mounting bolt of this type, a head provided at the base end, a shaft portion that is inserted through a through hole formed in the connecting rod and a through hole formed in the cap, and a nut formed at the tip are screwed together. It is known to have a male screw portion formed by hot forging. The outer peripheral surface other than the head of this bolt is machined by lathe processing and polishing, the shaft part is formed in steps, and the maximum outer diameter part of the shaft part is almost the same as the inner diameter of the through hole and the through hole. Can be finished. This same finishing is performed to ensure the roundness when the semicircular recess of the connecting rod and the semicircular recess of the cap are faced to each other and integrated.
【０００３】 しかし、上記取付ボルトは、熱間鍛造から頭部を除いた軸部を機械加工してい るため、高い精度を要するはめあい部以外の軸部にも旋盤加工を必要とし、結果 として加工工数が非常に多く、製造コストを押上げる問題点があった。However, since the mounting bolt is machined from the shaft portion excluding the head portion from hot forging, the shaft portion other than the fitting portion that requires high accuracy also needs to be machined, resulting in machining. The number of man-hours is very large, which causes a problem of increasing the manufacturing cost.
【０００４】 これらの点を解消するために、比較的高い精度の加工に適した冷間鍛造により 形成された取付ボルトが知られている。この取付ボルトでははめあい部以外の軸 部の加工は不要であって、はめあい部の軸部にのみ所定の幅を有する複数の斜目 のローレット目が所定の間隔をあけて付与される。これらの斜目のローレット目 が付与された外周面がセンタレス研摩盤により通孔及び透孔の孔径と略同一の外 径になるように研摩される。斜目のローレット目を付与するのは平目のローレッ ト目を付与すると外周面が不連続となり、センタレスではめあい部を研摩できな いためである。In order to solve these problems, a mounting bolt formed by cold forging that is suitable for relatively accurate machining is known. This mounting bolt does not require machining of the shaft part other than the fitting part, and only the shaft part of the fitting part is provided with a plurality of beveled knurls having a predetermined width at predetermined intervals. The outer peripheral surface provided with these knurled knurls is polished by a centerless polishing machine so that the outer diameter is approximately the same as the diameters of the through holes and the through holes. The sloped knurling is applied because the flat outer knurling causes discontinuity in the outer peripheral surface and it is not possible to polish the mating part with centerless.

しかし、上記取付ボルトでは、斜目のローレット目に締りばめの機能が付与さ れるため、このボルトを通孔に打込むときにこのボルトが斜目のローレット目に 沿って回転してしまう不具合があった。このため予めどれだけ回転するが見込ん で打込まなければならず、ボルトの組付作業が煩わしい問題点があった。 However, the above-mentioned mounting bolts have an interference fit function for the knurled ridges, which causes the bolts to rotate along the knurled ridges when driven into the through hole. was there. For this reason it must be implanted in advance how much is expected but is rotated, the assembly work of the bolt there has been a troublesome problem.
【０００６】 本考案の目的は、加工工数及び組付工数を低減することにより、製造コストを 低減でき、生産性を向上できる締りばめ機能を有する取付ボルトを提供すること にある。An object of the present invention is to provide a mounting bolt having an interference fit function that can reduce the manufacturing cost and the productivity by reducing the processing man-hours and the assembly man-hours.
