Description

この発明は、内視鏡又は内視鏡部品を製造する際の内視鏡の部品どうしの仮止め固定方法に関する。   The present invention relates to a method for temporarily fixing and fixing parts of an endoscope when manufacturing an endoscope or an endoscope part.

内視鏡又は内視鏡部品を製造する際には、二つの部品をロー付け、半田付け或いは接着等で連結固着する作業が非常に多く必要とされ、送気送水又は吸引等のための配管パイプをその相手方部品である操作弁等に接続する場合には、相手方部品に形成された孔に配管パイプの端部を差し込んだ状態で銀ロー付け等で固着している。   When manufacturing endoscopes or endoscope parts, it is necessary to braze the two parts together and connect and fix them by soldering or bonding, etc., and piping for air supply / water supply or suction etc. When the pipe is connected to an operation valve or the like which is a counterpart component, the pipe is fixed by silver brazing or the like with the end of the pipe pipe inserted into a hole formed in the counterpart component.

ただし多くの場合、操作弁に対する配管パイプの突出方向は非常に厳密さが求められるので、ロー付けによる固着作業を行うのに先立って配管パイプを操作弁に対して設計通りの向きに仮止め固定して、固着作業の際に動かないようにしておく必要がある。   In many cases, however, the pipe pipe projecting direction with respect to the operation valve is required to be very strict, so the pipe pipe is temporarily fixed to the operation valve in the designed direction prior to fixing work by brazing. Therefore, it is necessary to keep it from moving during the fixing work.

そこで従来は、配管パイプが差し込まれる孔側にレーザによる肉盛溶接等で突起を形成したり、孔の縁部をポンチでかしめ（矢弦かしめ）て変形させることで、配管パイプを操作弁に仮止め固定していた（例えば、特許文献１）。
特開２００５−９５５８６、段落〔００５８〕〜〔００６９〕 Therefore, conventionally, a pipe pipe is used as an operation valve by forming a protrusion on the hole side into which the pipe pipe is inserted by laser welding or by staking the edge of the hole with a punch. It was temporarily fixed (for example, Patent Document 1).
JP 2005-95586, paragraphs [0058]-[0069]

しかし、上述のように配管パイプが差し込まれる孔側にレーザによる肉盛溶接等で突起を形成するのは、「仮止め固定」という補助的な工程のために大きなコストがかかって好ましくない。また、孔の縁部をポンチでかしめる作業を行うと、作業に非常に時間がかかるだけでなく、仮止め固定の対象である配管パイプをポンチで変形させてしまう場合がある。   However, it is not preferable to form a protrusion on the hole side into which the pipe is inserted as described above by laser welding or the like because of the auxiliary process of “temporarily fixing”. Further, when the work of caulking the edge of the hole with a punch, not only does the work take much time, but the piping pipe that is temporarily fixed may be deformed with the punch.

そこで本発明は、内視鏡に用いられる二つの部品の一方に形成された孔に他方の端部を差し込んでから二つの部品を互いにぐらつかない状態にするための仮止め固定を、低コストでしかも孔に差し込まれる部品を変形させることなく確実かつ容易に行うことができる内視鏡の部品どうしの仮止め固定方法を提供することを目的とする。   Therefore, the present invention provides low-cost temporary fixing for inserting the other end into a hole formed in one of the two parts used in the endoscope and preventing the two parts from wobbling with each other. Moreover, it is an object of the present invention to provide a method for temporarily fixing and fixing parts of an endoscope that can be reliably and easily performed without deforming a part inserted into a hole.

上記の目的を達成するため、本発明の内視鏡の部品どうしの仮止め固定方法は、内視鏡に用いられる二つの部品の一方に形成された孔に他方の端部を差し込んでから二つの部品を互いに固着する際に、その固着作業を行うのに先立って二つの部品を互いにぐらつかない状態に仮止め固定するための内視鏡の部品どうしの仮止め固定方法において、一方の部品に形成された孔の開口部に隣接して一方の部品の表面に溝を形成することにより、孔の開口部と溝との間に薄肉の隔壁を形成しておき、孔に他方の部品の端部を差し込んでから、溝内に工具の先端を差し込んで隔壁を他方の部品側に傾いた状態に塑性変形させることにより、二つの部品が仮止め固定されるようにしたものである。   In order to achieve the above object, the method of temporarily fixing and fixing parts of an endoscope according to the present invention includes inserting the other end into a hole formed in one of two parts used in an endoscope, and then When fixing two parts to each other, in the temporary fixing fixing method of the endoscope parts to fix the two parts temporarily without fixing each other prior to fixing the two parts, By forming a groove on the surface of one part adjacent to the opening of the formed hole, a thin partition is formed between the opening of the hole and the groove, and the end of the other part is formed in the hole. After inserting the part, the tip of the tool is inserted into the groove, and the partition wall is plastically deformed in a state inclined to the other part side, whereby the two parts are temporarily fixed.

なお、他方の部品がパイプ状の部品であってもよく、それが配管パイプであってもよい。また、溝が直線溝であってもよく、直線溝が相違する向きに複数形成されて、例えば略９０°相違する向きに二つ、或いは略６０°ずつ相違する向きに三つ形成されていてもよい。   The other part may be a pipe-like part, or it may be a piping pipe. Also, the groove may be a straight groove, and a plurality of linear grooves are formed in different directions, for example, two in different directions of about 90 °, or three in directions different from each other by about 60 °. Also good.

また、溝が孔の外縁に沿って環状に形成されていてもよく、隔壁の基部と溝の底面とをつなぐ壁面が円弧状に形成されていてもよい。   The groove may be formed in an annular shape along the outer edge of the hole, and the wall surface connecting the base of the partition wall and the bottom surface of the groove may be formed in an arc shape.

本発明によれば、一方の部品に形成された孔の開口部に隣接して一方の部品の表面に溝を形成して孔の開口部と溝との間に薄肉の隔壁を形成し、孔に他方の部品の端部を差し込んでから溝内に工具の先端を差し込んで隔壁を他方の部品側に傾いた状態に塑性変形させることで、二つの部品が仮止め固定されるようにしたことにより、仮止め固定を、低コストでしかも孔に差し込まれる部品を変形させることなく確実かつ容易に行うことができる。   According to the present invention, a groove is formed on the surface of one part adjacent to the opening of the hole formed in one part, and a thin partition is formed between the opening of the hole and the groove. The two parts were temporarily fixed by inserting the end of the other part into the groove and then inserting the tip of the tool into the groove and plastically deforming the partition wall to tilt toward the other part. Thus, the temporary fixing can be reliably and easily performed at a low cost and without deforming a component inserted into the hole.

内視鏡に用いられる二つの部品の一方に形成された孔に他方の端部を差し込んでから二つの部品を互いに固着する際に、その固着作業を行うのに先立って二つの部品を互いにぐらつかない状態に仮止め固定するための内視鏡の部品どうしの仮止め固定方法において、一方の部品に形成された孔の開口部に隣接して一方の部品の表面に溝を形成することにより、孔の開口部と溝との間に薄肉の隔壁を形成しておき、孔に他方の部品の端部を差し込んでから、溝内に工具の先端を差し込んで隔壁を他方の部品側に傾いた状態に塑性変形させることにより、二つの部品が仮止め固定されるようにする。   When the two parts are fixed to each other after inserting the other end into a hole formed in one of the two parts used in the endoscope, the two parts are wobbled to each other prior to performing the fixing operation. In the temporary fixing fixing method of the parts of the endoscope for temporarily fixing and fixing in a state where there is no, by forming a groove on the surface of one part adjacent to the opening of the hole formed in one part, A thin partition was formed between the opening of the hole and the groove, and the end of the other part was inserted into the hole, and then the tip of the tool was inserted into the groove and the partition was tilted toward the other part. By plastically deforming the two parts, the two parts are temporarily fixed.

図面を参照して本発明の実施例を説明する。
図２において、１は内視鏡の操作部であり、その上半部前面には送気送水操作弁２と吸引操作弁３が並んで配置されている。 Embodiments of the present invention will be described with reference to the drawings.
In FIG. 2, reference numeral 1 denotes an operation portion of the endoscope, and an air / water supply operation valve 2 and a suction operation valve 3 are arranged side by side on the front surface of the upper half.

吸引操作弁３のシリンダ体４はステンレス鋼等で形成されて操作部１内に配置されていて、シリンダ体４の側面及び底面に接続されたステンレス鋼管製の配管パイプ５に可撓性の配管チューブ６が接続され、配管パイプ５と配管チューブ６との接続部は固定環７により接続状態が固定されている。   The cylinder body 4 of the suction operation valve 3 is formed of stainless steel or the like and disposed in the operation portion 1, and a flexible pipe is connected to a pipe pipe 5 made of stainless steel pipe connected to the side surface and the bottom surface of the cylinder body 4. The tube 6 is connected, and the connection state between the pipe 5 and the pipe 6 is fixed by a fixed ring 7.

図３は配管パイプ５とシリンダ体４との接続部を示しており、シリンダ体４に形成された孔９に配管パイプ５の端部が差し込まれた状態で、シリンダ体４と配管パイプ５とが例えば銀ロー付けにより互いに固着されている。   FIG. 3 shows a connecting portion between the piping pipe 5 and the cylinder body 4. With the end of the piping pipe 5 inserted into the hole 9 formed in the cylinder body 4, Are fixed to each other by, for example, silver brazing.

図４は、製造に際してシリンダ体４の孔９に配管パイプ５が固着される前の状態を示しており、固着作業を行うのに先立って、シリンダ体４と配管パイプ５とを互いにぐらつかない状態に仮止め固定するために、シリンダ体４には、孔９の開口部に隣接して直線溝１０が形成され、それによって、孔９の開口部と直線溝１０との間に薄肉の隔壁１１が形成されている。   FIG. 4 shows a state before the pipe pipe 5 is fixed to the hole 9 of the cylinder body 4 in manufacturing, and the cylinder body 4 and the pipe pipe 5 do not wobble each other prior to performing the fixing operation. In order to temporarily fix the cylinder body 4 to the cylinder body 4, a straight groove 10 is formed adjacent to the opening of the hole 9, whereby a thin partition wall 11 is formed between the opening of the hole 9 and the linear groove 10. Is formed.

図５は、孔９と直線溝１０を正面から見た状態を示している。直線溝１０は略９０°相違する向きに二つ形成されており、IV−IV断面（二箇所）がいずれも前出の図４に図示される状態に形成されている。   FIG. 5 shows a state in which the hole 9 and the straight groove 10 are viewed from the front. Two straight grooves 10 are formed in directions different from each other by approximately 90 °, and both IV-IV cross sections (two locations) are formed in the state shown in FIG.

各直線溝１０は、VI−VI断面（二箇所）を図示する図６に示されるように、一つのカッターでシリンダ体４の表面から円弧状に掘り下げ加工することで、極めて容易に低コストで形成することができる。   As shown in FIG. 6 illustrating the VI-VI cross section (two places), each linear groove 10 is extremely easily and inexpensively formed by digging in a circular arc shape from the surface of the cylinder body 4 with one cutter. Can be formed.

図４に戻って、配管パイプ５の直径が例えば３〜５ｍｍ程度の場合、直線溝１０の深さｄと幅ｗは、例えばｄ＝０．５〜１．０ｍｍ程度、ｗ＝０．５〜１．０ｍｍ程度の範囲にあるのが適当であり、隔壁１１の厚みｔはｔ＝０．０５〜０．３ｍｍ程度の範囲にあるのがよい。   Returning to FIG. 4, when the diameter of the piping pipe 5 is, for example, about 3 to 5 mm, the depth d and the width w of the linear groove 10 are, for example, about d = 0.5 to 1.0 mm, w = 0.5 to It is appropriate that the thickness is in the range of about 1.0 mm, and the thickness t of the partition wall 11 is preferably in the range of about t = 0.05 to 0.3 mm.

本発明においては、このように構成された実施例のシリンダ体４と配管パイプ５とを銀ロー付けで固着する前に、図４に示される状態から図１に示されるように、シリンダ体４の孔９に配管パイプ５を差し込んだら、直線溝１０内に例えばマイナスドライバー状の工具１００の先端を差し込んで、隔壁１１を配管パイプ５側に傾いた状態に塑性変形させる。それによって、配管パイプ５の端部が側方から隔壁１１で押圧されて配管パイプ５がシリンダ体４に対して仮止め固定された状態になる。   In the present invention, before the cylinder body 4 and the pipe pipe 5 of the embodiment configured as described above are fixed by silver brazing, as shown in FIG. 1 from the state shown in FIG. When the piping pipe 5 is inserted into the hole 9, the tip of a flat screwdriver tool 100 is inserted into the straight groove 10, and the partition wall 11 is plastically deformed to be inclined to the piping pipe 5 side. Thereby, the end of the piping pipe 5 is pressed by the partition wall 11 from the side, and the piping pipe 5 is temporarily fixed to the cylinder body 4.

このような仮止め固定方法においては、直線溝１０を形成加工するだけで形成された薄肉の隔壁１１を、工具１００で変形させるだけの作業で配管パイプ５をシリンダ体４に対して仮止め固定することができるので、簡単な作業で低コストで実施することができ、仮止め固定するための力の調節が容易なので、配管パイプ５を変形させる恐れもない。   In such a temporary fixing method, the pipe 5 is temporarily fixed to the cylinder body 4 by simply deforming the thin partition wall 11 formed only by forming the linear groove 10 with the tool 100. Therefore, it is possible to carry out with a simple operation at a low cost, and since it is easy to adjust the force for temporarily fixing and fixing, there is no possibility of deforming the piping pipe 5.

なお、本発明は上記実施例に限定されるものではなく、例えば図７に示されるように直線溝１０が一つだけ形成されたもの、或いは、図８に示されるように、直線溝１０が略６０°ずつ相違する向きに三つ形成されたもの等であってもよい。   The present invention is not limited to the above-described embodiment. For example, as shown in FIG. 7, only one straight groove 10 is formed, or as shown in FIG. Three or the like formed in different directions by approximately 60 ° may be used.

また、図９に示されるように、隔壁１１を形成するための溝として、孔９の外縁に沿う環状溝２０を形成してもよい。また、図１０に示されるように、隔壁１１の基部と直線溝１０の底面とをつなぐ壁面１２を円弧状に形成すれば、隔壁１１を塑性変形させる際に隔壁１１の基部がひび割れする可能性等を小さくすることができる。   Further, as shown in FIG. 9, an annular groove 20 along the outer edge of the hole 9 may be formed as a groove for forming the partition wall 11. In addition, as shown in FIG. 10, if the wall surface 12 that connects the base portion of the partition wall 11 and the bottom surface of the linear groove 10 is formed in an arc shape, the base portion of the partition wall 11 may crack when the partition wall 11 is plastically deformed. Etc. can be reduced.

また、本発明は吸引操作弁３のシリンダ体４に対する配管パイプ５の接続固着部に限らず、送気送水操作弁２やその他の部分の二つの部品の接続固着部に適用することができ、ロー付け以外の半田付け、溶接或いは接着等により固着が行われる部分の仮止め固定にも適用することができる。   The present invention can be applied not only to the connection fixing portion of the pipe pipe 5 to the cylinder body 4 of the suction operation valve 3, but also to the connection fixing portion of the two parts of the air / water supply operation valve 2 and other parts, The present invention can also be applied to temporary fixing of a portion where fixing is performed by soldering, welding or adhesion other than brazing.
