Description

本発明は、カラーの圧入構造に関する。 The present invention relates to a collar press-fit structure.

特許文献１には、内燃機関用のフィルタ装置が開示されている。
特許文献１に記載のフィルタ装置のサイクロン予分離機は、貫通孔が形成された樹脂製の固定部を備えている。貫通孔には、円筒状の金属製のブッシュが圧入されている。ブッシュにねじを挿通し、当該ねじをフィルタハウジングのブッシュに螺入することによって、サイクロン予分離機がフィルタハウジングに固定される。 Patent Document 1 discloses a filter device for an internal combustion engine.
The cyclone pre-separator of the filter device described in Patent Document 1 includes a resin fixing portion having through holes formed therein. A cylindrical metal bush is press-fitted into the through hole. The cyclone pre-separator is fixed to the filter housing by inserting a screw through the bush and screwing the screw into the bush of the filter housing.

特表２０１３−５０７２４８号公報Special Table 2013-507248

ところで、こうしたブッシュ（以下、カラーと称する。）の圧入構造においては、貫通孔の内径がカラーの外径よりも小さく設定されている。そのため、カラーを貫通孔に圧入する際に、貫通孔の内周面がカラーの端縁によって削られることにより削りかす、所謂バリが発生する。このようにして発生したバリが貫通孔からはみ出すことで、ねじの頭部とカラーの端面との間、あるいは固定対象とカラーの端面との間に挟まると、固定部を固定対象に対して規定の締め付けトルクにてねじ固定することができないおそれがある。こうしたことから、バリの発生量が低減されるように、固定部を成形する金型の設計やその修正に時間を要するといった問題や、圧入工程において発生したバリを除去する工程が別途必要となるといった問題が生じる。 By the way, in the press-fitting structure of such a bush (hereinafter referred to as a collar), the inner diameter of the through hole is set to be smaller than the outer diameter of the collar. Therefore, when the collar is press-fitted into the through hole, the inner peripheral surface of the through hole is scraped by the edge of the collar, which causes shavings, so-called burrs. When the burr generated in this way protrudes from the through hole and is sandwiched between the head of the screw and the end face of the collar, or between the fixing target and the end face of the collar, the fixing portion is defined with respect to the fixing target. It may not be possible to fix the screws with the tightening torque of. For these reasons, in order to reduce the amount of burrs generated, there is a problem that it takes time to design and modify the mold for molding the fixed part, and a separate process for removing burrs generated in the press-fitting process is required. Such a problem arises.

本発明の目的は、貫通孔からのバリのはみ出しを抑制できるカラーの圧入構造を提供することにある。 An object of the present invention is to provide a collar press-fitting structure capable of suppressing the protrusion of burrs from through holes.

上記目的を達成するためのカラーの圧入構造は、貫通孔が形成された樹脂製の固定部と、前記貫通孔に対して圧入される円筒状のカラーとを備える。前記貫通孔に対する前記カラーの圧入方向の前側及び後側を前側及び後側とするとき、前記貫通孔の内周面には、前記カラーの外周面に沿うとともに前記外周面に当接する当接部と、前記貫通孔の周方向の一部に設けられ、前記カラーが圧入されていない状態において前記当接部よりも内周側に突出する一方、前記カラーが圧入された状態において前記カラーの外周面を押圧する押圧部と、が設けられている。前記貫通孔の内周面のうち前記押圧部よりも前側には、前記カラーの外周面との間に隙間を形成する逃がし凹部が、前記押圧部よりも前側であり、且つ前記貫通孔の径方向において前記押圧部と重なり合う位置に設けられている。 The press-fitting structure of the collar for achieving the above object includes a resin fixing portion having a through hole formed therein and a cylindrical collar press-fitted into the through hole. When the front side and the rear side of the collar in the press-fitting direction with respect to the through hole are the front side and the rear side, the inner peripheral surface of the through hole is a contact portion that follows the outer peripheral surface of the collar and abuts on the outer peripheral surface. And, it is provided in a part of the circumferential direction of the through hole, and protrudes toward the inner peripheral side from the contact portion in a state where the collar is not press-fitted, while the outer periphery of the collar is provided in a state where the collar is press-fitted. A pressing portion for pressing the surface is provided. On the inner peripheral surface of the through hole on the front side of the pressing portion, a relief recess forming a gap with the outer peripheral surface of the collar is on the front side of the pressing portion and the diameter of the through hole. It is provided at a position where it overlaps with the pressing portion in the direction.

同構成によれば、貫通孔の内周面に設けられた押圧部によってカラーの外周面が押圧されることで貫通孔に対してカラーが圧入される。また、貫通孔の内周面に設けられた当接部によってカラーの外周面が当接されて支持されることにより、カラーのガタ付きが抑制される。ここで、貫通孔の内周面に設けられた逃がし凹部によってカラーの外周面と貫通孔との間に隙間が形成される。このため、貫通孔に対してカラーが圧入される際に、当接部よりも内周側に突出する押圧部がカラーの端縁によって削られることによって発生するバリが、カラーの圧入に伴って押し出されて上記隙間に収納されるようになる。したがって、貫通孔からのバリのはみ出しを抑制することができる。 According to the same configuration, the collar is press-fitted into the through hole by pressing the outer peripheral surface of the collar by the pressing portion provided on the inner peripheral surface of the through hole. Further, the outer peripheral surface of the collar is abutted and supported by the abutting portion provided on the inner peripheral surface of the through hole, so that the backlash of the collar is suppressed. Here, a gap is formed between the outer peripheral surface of the collar and the through hole by the relief recess provided on the inner peripheral surface of the through hole. For this reason, when the collar is press-fitted into the through hole, burrs generated by scraping the pressing portion protruding inward from the contact portion by the edge of the collar are caused by the press-fitting of the collar. It will be pushed out and stored in the above gap. Therefore, it is possible to suppress the protrusion of burrs from the through hole.

本発明によれば、貫通孔からのバリのはみ出しを抑制することができる。 According to the present invention, it is possible to suppress the protrusion of burrs from the through hole.

以下、図１〜図８を参照して、カラーの圧入構造の一実施形態について説明する。
図１及び図２に示すように、カラーの圧入構造は、貫通孔２０が形成された樹脂製の固定部１０と、貫通孔２０に対し、貫通孔２０の軸線方向に沿って圧入される円筒状のカラー３０とを備える。本実施形態のカラー３０は、金属製のカラーである。 Hereinafter, an embodiment of the color press-fitting structure will be described with reference to FIGS. 1 to 8.
As shown in FIGS. 1 and 2, the collar press-fitting structure is a resin fixing portion 10 in which the through hole 20 is formed and a cylinder that is press-fitted into the through hole 20 along the axial direction of the through hole 20. The shape of the collar 30 is provided. The color 30 of the present embodiment is a metal color.

まず、図１〜図４を参照して、カラー３０が貫通孔２０に圧入された状態の固定部１０における貫通孔２０の基本構成について説明する。なお、以降において、貫通孔２０に対するカラー３０の圧入方向Ａの前側及び後側を、単に「前側」及び「後側」として説明する。また、貫通孔２０の周方向を単に周方向として説明する。 First, with reference to FIGS. 1 to 4, the basic configuration of the through hole 20 in the fixing portion 10 in which the collar 30 is press-fitted into the through hole 20 will be described. Hereinafter, the front side and the rear side of the collar 30 in the press-fitting direction A with respect to the through hole 20 will be described simply as "front side" and "rear side". Further, the circumferential direction of the through hole 20 will be described simply as the circumferential direction.

図１〜図４に示すように、貫通孔２０の内周面２１には、カラー３０の外周面３１に沿うとともに当接する複数の当接部２２と、外周面３１を押圧する複数の押圧部２３とが周方向において交互に設けられている。本実施形態では、４つの当接部２２が、周方向において等間隔にて設けられている。また、４つの押圧部２３が、周方向において等間隔にて設けられている。 As shown in FIGS. 1 to 4, the inner peripheral surface 21 of the through hole 20 has a plurality of abutting portions 22 that abut along the outer peripheral surface 31 of the collar 30 and a plurality of pressing portions that press the outer peripheral surface 31. 23 and 23 are provided alternately in the circumferential direction. In this embodiment, four contact portions 22 are provided at equal intervals in the circumferential direction. Further, four pressing portions 23 are provided at equal intervals in the circumferential direction.

図１及び図３に示すように、貫通孔２０の内周面２１のうち押圧部２３よりも前側には、カラー３０の外周面３１との間に隙間Ｓを形成する逃がし凹部２４が設けられている。
図３に示すように、逃がし凹部２４の内周面は、前側ほど外周側に位置するように傾斜している。したがって、逃がし凹部２４の内周面とカラー３０の外周面３１との間隔は、前側ほど大きい。逃がし凹部２４は、貫通孔２０の前端２５まで延びている。 As shown in FIGS. 1 and 3, a relief recess 24 for forming a gap S between the inner peripheral surface 21 of the through hole 20 and the outer peripheral surface 31 of the collar 30 is provided on the front side of the pressing portion 23. ing.
As shown in FIG. 3, the inner peripheral surface of the relief recess 24 is inclined so as to be located on the outer peripheral side toward the front side. Therefore, the distance between the inner peripheral surface of the relief recess 24 and the outer peripheral surface 31 of the collar 30 is larger toward the front side. The relief recess 24 extends to the front end 25 of the through hole 20.

次に、図５〜図８を参照して、カラー３０が圧入されていない状態の貫通孔２０の構成について説明する。
図５及び図６に示すように、各当接部２２の内周面は、同一の仮想円Ｖ上に位置している。各押圧部２３は、各当接部２２、すなわち仮想円Ｖよりも内周側に突出している。各押圧部２３は、仮想円Ｖの接線方向に沿って延びている。なお、以降において、当接部２２よりも内周側に突出した状態の押圧部２３を押圧部２３Ｂとして区別して説明する。本実施形態では、押圧部２３Ｂの突出部分の体積は、逃がし凹部２４によって形成される隙間Ｓの容積よりも小さい。 Next, the configuration of the through hole 20 in a state where the collar 30 is not press-fitted will be described with reference to FIGS. 5 to 8.
As shown in FIGS. 5 and 6, the inner peripheral surfaces of the contact portions 22 are located on the same virtual circle V. Each pressing portion 23 projects toward each contact portion 22, that is, the virtual circle V on the inner peripheral side. Each pressing portion 23 extends along the tangential direction of the virtual circle V. Hereinafter, the pressing portion 23 in a state of protruding toward the inner peripheral side of the contact portion 22 will be described separately as the pressing portion 23B. In the present embodiment, the volume of the protruding portion of the pressing portion 23B is smaller than the volume of the gap S formed by the relief recess 24.

図５及び図７に示すように、逃がし凹部２４は、押圧部２３Ｂよりも前側であり、且つ貫通孔２０の径方向において押圧部２３Ｂと重なり合う位置に設けられている。図５に示すように、本実施形態では、４つの逃がし凹部２４が、４つの押圧部２３Ｂに対応する位置にそれぞれ設けられている。逃がし凹部２４の両端２４ａは、周方向において、押圧部２３Ｂの両端２３ａよりもそれぞれ外側に位置している。 As shown in FIGS. 5 and 7, the relief recess 24 is provided on the front side of the pressing portion 23B and at a position where it overlaps with the pressing portion 23B in the radial direction of the through hole 20. As shown in FIG. 5, in the present embodiment, four relief recesses 24 are provided at positions corresponding to the four pressing portions 23B, respectively. Both ends 24a of the relief recess 24 are located outside the both ends 23a of the pressing portion 23B in the circumferential direction.

図６に示すように、貫通孔２０の後側の開口２６には、前側ほど内径が小さくされた案内面２６ａが全周にわたって設けられている。
図７及び図８に示すように、貫通孔２０には、後端から前端にかけて、案内面２６ａ、押圧部２３Ｂ、及び逃がし凹部２４が順に隣り合っている。 As shown in FIG. 6, the opening 26 on the rear side of the through hole 20 is provided with a guide surface 26a having an inner diameter smaller toward the front side over the entire circumference.
As shown in FIGS. 7 and 8, the guide surface 26a, the pressing portion 23B, and the relief recess 24 are adjacent to each other in this order from the rear end to the front end in the through hole 20.

次に、本実施形態の作用について説明する。
図１及び図３に示すように、貫通孔２０の内周面２１に設けられた押圧部２３によってカラー３０の外周面３１が押圧されることで貫通孔２０に対してカラー３０が圧入される。また、貫通孔２０の内周面２１に設けられた当接部２２によってカラー３０の外周面３１が当接されて支持されることにより、カラー３０のガタ付きが抑制される。ここで、貫通孔２０の内周面２１に設けられた逃がし凹部２４によってカラー３０の外周面３１と貫通孔２０との間に隙間Ｓが形成される。このため、貫通孔２０に対してカラー３０が圧入される際に、当接部２２よりも内周側に突出する押圧部２３Ｂがカラー３０の端縁により削られて押圧部２３になることによって発生するバリが、カラー３０の圧入に伴って押し出されて上記隙間Ｓに収納されるようになる。 Next, the operation of this embodiment will be described.
As shown in FIGS. 1 and 3, the collar 30 is press-fitted into the through hole 20 by pressing the outer peripheral surface 31 of the collar 30 by the pressing portion 23 provided on the inner peripheral surface 21 of the through hole 20. .. Further, the outer peripheral surface 31 of the collar 30 is abutted and supported by the contact portion 22 provided on the inner peripheral surface 21 of the through hole 20, so that the backlash of the collar 30 is suppressed. Here, a gap S is formed between the outer peripheral surface 31 of the collar 30 and the through hole 20 by the relief recess 24 provided on the inner peripheral surface 21 of the through hole 20. Therefore, when the collar 30 is press-fitted into the through hole 20, the pressing portion 23B protruding toward the inner peripheral side of the contact portion 22 is scraped by the edge of the collar 30 to become the pressing portion 23. The generated burrs are pushed out as the collar 30 is press-fitted and are stored in the gap S.

次に、本実施形態の効果について説明する。
（１）貫通孔２０の内周面２１のうち押圧部２３よりも前側には、カラー３０の外周面３１との間に隙間Ｓを形成する逃がし凹部２４が、押圧部２３よりも前側であり、且つ貫通孔２０の径方向において押圧部２３と重なり合う位置に設けられている。 Next, the effect of this embodiment will be described.
(1) On the inner peripheral surface 21 of the through hole 20 on the front side of the pressing portion 23, a relief recess 24 forming a gap S with the outer peripheral surface 31 of the collar 30 is on the front side of the pressing portion 23. In addition, it is provided at a position where it overlaps with the pressing portion 23 in the radial direction of the through hole 20.

こうした構成によれば、上述した作用を奏することから、貫通孔２０からのバリのはみ出しを抑制することができる。
（２）複数の押圧部２３Ｂが、周方向において互いに間隔をおいて設けられており、複数の逃がし凹部２４が、複数の押圧部２３Ｂに対応する位置にそれぞれ設けられている。 According to such a configuration, since the above-mentioned action is obtained, it is possible to suppress the protrusion of burrs from the through hole 20.
(2) A plurality of pressing portions 23B are provided at intervals in the circumferential direction, and a plurality of relief recesses 24 are provided at positions corresponding to the plurality of pressing portions 23B, respectively.

こうした構成によれば、複数の押圧部２３Ｂが周方向において互いに間隔をおいて設けられているため、カラー３０の中心を貫通孔２０の中心に容易に合わせることができる。これにより、貫通孔２０に対するカラー３０の圧入を容易且つ安定して行うことができる。また、複数の押圧部２３Ｂが削られることによって発生するバリが、複数の押圧部２３Ｂに対応する位置にそれぞれ設けられた複数の逃がし凹部２４とカラー３０の外周面３１との間に形成される複数の隙間Ｓに収納されるようになる。したがって、貫通孔２０からのバリのはみ出しを効果的に抑制することができる。 According to such a configuration, since the plurality of pressing portions 23B are provided at intervals in the circumferential direction, the center of the collar 30 can be easily aligned with the center of the through hole 20. As a result, the collar 30 can be easily and stably press-fitted into the through hole 20. Further, burrs generated by scraping the plurality of pressing portions 23B are formed between the plurality of relief recesses 24 provided at positions corresponding to the plurality of pressing portions 23B and the outer peripheral surface 31 of the collar 30. It will be stored in a plurality of gaps S. Therefore, it is possible to effectively suppress the protrusion of burrs from the through hole 20.

（３）逃がし凹部２４は、貫通孔２０の前端２５まで延びている。
こうした構成によれば、逃がし凹部２４とカラー３０の外周面３１との間に形成される隙間Ｓの容積を大きくすることができ、当該隙間Ｓに多くのバリを収納することができる。 (3) The relief recess 24 extends to the front end 25 of the through hole 20.
According to such a configuration, the volume of the gap S formed between the relief recess 24 and the outer peripheral surface 31 of the collar 30 can be increased, and a large number of burrs can be stored in the gap S.

また、上記構成によれば、逃がし凹部２４が貫通孔２０の前端まで延びているため、逃がし凹部２４がアンダーカット形状となりにくく、固定部１０を成形する成形型の構成が簡単となる。これにより、貫通孔２０を有する固定部１０を容易に型成形することができる。 Further, according to the above configuration, since the relief recess 24 extends to the front end of the through hole 20, the relief recess 24 is unlikely to have an undercut shape, and the structure of the molding mold for molding the fixing portion 10 becomes simple. As a result, the fixed portion 10 having the through hole 20 can be easily molded.

（４）逃がし凹部２４の周方向における両端２４ａは、周方向において、押圧部２３Ｂの両端２３ａよりもそれぞれ外側に位置している。
こうした構成によれば、押圧部２３Ｂが削られることによって発生するバリの一部が、逃がし凹部２４とカラー３０の外周面３１との間に形成される隙間Ｓに収納されないといった不都合の発生を抑制できる。 (4) Both ends 24a of the relief recess 24 in the circumferential direction are located outside the both ends 23a of the pressing portion 23B in the circumferential direction.
According to such a configuration, it is possible to suppress the occurrence of inconvenience such that a part of the burr generated by scraping the pressing portion 23B is not stored in the gap S formed between the relief recess 24 and the outer peripheral surface 31 of the collar 30. it can.
