Description

本発明は、長手方向に任意な間隔で公差を有して複数個の検査対象物が配設された長尺検査対象体において、前記検査対象物の相対位置を検査する相対位置検査方法及び装置に関する。 The present invention relates to a relative position inspection method and apparatus for inspecting a relative position of an inspection object in a long inspection object in which a plurality of inspection objects are provided with tolerances at arbitrary intervals in the longitudinal direction. About.

長手方向に所定の間隔で、公差を有して複数個の検査対象物が配設された長尺な中間工業製品が存在する。この様な中間工業製品においては、次工程の組立作業時に支障を来たさない様、事前に前記検査対象物の相対位置を検査する必要がある。 There is a long intermediate industrial product in which a plurality of inspection objects are provided with tolerances at predetermined intervals in the longitudinal direction. In such an intermediate industrial product, it is necessary to inspect the relative position of the inspection object in advance so as not to hinder the assembly work in the next process.

例えば、この様な中間工業製品の例として、ディーゼルエンジンのコモンレールシステム用リターンホースについて、添付図２を参照しながら説明する。図２は、コモンレールシステム用リターンホースを説明するための外形図である。このリターンホース１１は、４気筒ディーゼルエンジンの各気筒毎にあるインジェクター間を配管するリターンホースであり、前記インジェクターに接続するためのＬ字継手１２ａとＴ字継手１２ｂ〜１２ｄと燃料の逆流防止のための逆止弁１２ｅとを配設され、これらの継手１２ａ〜１２ｄと逆止弁１２ｅとを、各ホース１３により連結して構成されている。符号１４は、ホース１３を保護するためのプロテクタである。 For example, as an example of such an intermediate industrial product, a return hose for a diesel engine common rail system will be described with reference to FIG. FIG. 2 is an outline view for explaining a common rail system return hose. This return hose 11 is a return hose that pipes between the injectors for each cylinder of the four-cylinder diesel engine. The L-shaped joint 12a and T-shaped joints 12b to 12d for connecting to the injector and the backflow prevention of fuel are provided. The check valve 12e is disposed, and the joints 12a to 12d and the check valve 12e are connected to each other by the hose 13. Reference numeral 14 denotes a protector for protecting the hose 13.

そして、このリターンホース１１に配設されたＬ字継手１２ａ、Ｔ字継手１２ｂ〜１２ｄ及び逆止弁１２ｅの相対的位置は、夫々のホース１３によって連結され隣接する継手１２ａ〜１２ｄあるいは逆止弁１２ｅ夫々の間隔Ｌ１〜Ｌ４が、図２に示す如く所定の寸法公差に収まる様に組立てられていなくてはならない。しかしながら、この様な寸法公差は、例えば、左端のＬ字継手１２ａを基準として、右方向に各Ｔ字継手１２ｂ〜１２ｄと逆止弁１２ｅとの寸法を順次追って決められたものではないので、各間隔Ｌ１〜Ｌ４毎に検査する必要があり、マニュアルで検査するのが非常に煩雑であり検査精度も得にくい。 The relative positions of the L-shaped joint 12a, the T-shaped joints 12b to 12d and the check valve 12e disposed in the return hose 11 are connected by the respective hoses 13 and adjacent joints 12a to 12d or check valves. 12e must be assembled so that the intervals L1 to L4 fall within a predetermined dimensional tolerance as shown in FIG. However, such a dimensional tolerance is not determined, for example, by sequentially measuring the dimensions of the T-shaped joints 12b to 12d and the check valve 12e in the right direction with reference to the leftmost L-shaped joint 12a. It is necessary to inspect at intervals L1 to L4, and manual inspection is very complicated and it is difficult to obtain inspection accuracy.

一方、従来例に係る接点の溶接位置検査方法につき、添付図３を参照しながら説明する。図３は、従来例に係る接点の溶接位置検査方法を示す斜視図である。この従来例に係る接点の溶接位置検査方法によれば、基準孔３３を有する板ばね３１に接点３２が溶接されてなる接点ばね２１の製造において、検査治具５０に設けられた基準ピン５１に前記接点ばね２１の基準孔３３を嵌挿する。 On the other hand, a contact welding position inspection method according to a conventional example will be described with reference to FIG. FIG. 3 is a perspective view illustrating a contact welding position inspection method according to a conventional example. According to the welding position inspection method of the contact according to this conventional example, in the manufacture of the contact spring 21 in which the contact 32 is welded to the leaf spring 31 having the reference hole 33, the reference pin 51 provided on the inspection jig 50 is applied. The reference hole 33 of the contact spring 21 is inserted.

そして、前記検査治具５０の上面に開口し許容誤差範囲内に溶接された前記接点３２が挿入可能な溝５２と、この溝５２の側方に設けられ前記接点３２の位置が許容誤差範囲内であれば、前記接点３２の側方により遮蔽されるスリット５３を利用して、前記接点３２の溶接位置の良否判定を行うものである（特許文献１参照）。 A groove 52 into which the contact 32 opened to the upper surface of the inspection jig 50 and welded within the allowable error range can be inserted, and the position of the contact 32 provided on the side of the groove 52 is within the allowable error range. If so, the quality of the welding position of the contact 32 is judged using the slit 53 shielded by the side of the contact 32 (see Patent Document 1).

この様な接点の溶接位置検査方法を、上述した様なリターンホース１１を構成するＬ字継手１２ａ、Ｔ字継手１２ｂ〜１２ｄ及び逆止弁１２ｅの相対的位置検査に適用することは原理的には可能であるが、各間隔Ｌ１〜Ｌ４毎に前記検査治具５０に相当する検査治具を製作する必要がある上、何種類もある前記リターンホース１１全品種に対応して準備しなくてはならないという問題点がある。
特開平３−２１６２９１号公報 In principle, such a contact welding position inspection method is applied to the relative position inspection of the L-shaped joint 12a, the T-shaped joints 12b to 12d and the check valve 12e constituting the return hose 11 as described above. However, it is necessary to manufacture an inspection jig corresponding to the inspection jig 50 for each of the intervals L1 to L4, and there are many types of the return hose 11 and it is not necessary to prepare them. There is a problem that it must not.

The reason for this configuration is that the dimensional tolerances shown in FIG. 2 are defined for each of the intervals L1 to L4 between the inspection objects 12, so that these dimensional tolerances are prevented from being accumulated as errors. It is.

また、前記基台３に固定された前記基準支承手段２ｃは、このリターンホース１１に配設された複数個の検査対象物１２が図２に示す如く奇数個であれば、その一端側から数えて真中に位置する検査対象物１２を支承する支承手段２であるのが好ましい。一方、前記検査対象物１２の個数が偶数個の場合は、それらの真中に相当する検査対象物１２が存在しないため、真中に近い２個の検査対象物１２のうち何れか一方を支承する支承手段２を、基準支承手段２ｃとするのが好ましい。この様に構成すると、前記可動支承手段に積層して搭載する階層を低減して、相対位置検査装置１の構成を簡素化できるためである。 Further, the reference support means 2c fixed to the base 3 is counted from one end side if the plurality of inspection objects 12 arranged on the return hose 11 are odd as shown in FIG. It is preferable that the support means 2 support the inspection object 12 positioned in the middle. On the other hand, when the number of the inspection objects 12 is an even number, there is no inspection object 12 corresponding to the center of the inspection objects 12, so that one of the two inspection objects 12 close to the center is supported. The means 2 is preferably the reference support means 2c. This is because the configuration of the relative position inspection apparatus 1 can be simplified by reducing the number of layers stacked and mounted on the movable support means.

更に、本発明の実施の形態に係るリターンホースの継手や逆止弁の相対位置検査装置１には、前記基台３及び可動支承手段２ａ，２ｂ，２ｄ，２ｅのスライド台５ａ，５ｂ，５ｄ，５ｅに、各１本の触針６ａ，６ｂ，６ｄ，６ｅが取り付けられている。そして、前記触針６ａを挟み込む様に、前記可動支承手段２ａが搭載された可動支承手段２ｂのスライド台５ｂに、２本の電極７ａ，８ａが長手方向に対向して取り付けられている。 Further, the return hose joint and check valve relative position inspection device 1 according to the embodiment of the present invention includes the base 3 and the slide bases 5a, 5b, 5d of the movable support means 2a, 2b, 2d, 2e. , 5e, one stylus 6a, 6b, 6d, 6e is attached. Then, two electrodes 7a and 8a are attached to the slide base 5b of the movable support means 2b on which the movable support means 2a is mounted so as to sandwich the stylus 6a.

同様に、前記触針６ｂ，６ｄを夫々挟み込む様に、前記可動支承手段２ｂ，２ｄ各々が搭載された基台３に、２本の電極７ｂ，８ｂ及び７ｄ，８ｄが夫々長手方向に対向して取り付けられている。更に、触針６ｅを挟み込む様に、可動支承手段２ｅが搭載された可動支承手段２ｄのスライド台５ｄに、２本の電極７ｅ，８ｅが長手方向に対向して取り付けられている。 Similarly, two electrodes 7b, 8b and 7d, 8d are opposed to each other in the longitudinal direction on the base 3 on which the movable support means 2b, 2d are mounted so as to sandwich the stylus 6b, 6d, respectively. Attached. Further, two electrodes 7e and 8e are attached to the slide base 5d of the movable support means 2d on which the movable support means 2e is mounted so as to sandwich the stylus 6e.

更に、前記可動支承手段２ａ，２ｂ，２ｄ，２ｅのスライド台５の夫々に、水平方向に各１本取り付けられた触針６と、これらの可動支承手段２ａ，２ｂ，２ｄ，２ｅが搭載された基台３または可動支承手段５ｂ，５ｄの各々に取り付けられた電極７，８とを夫々含む図示しない通電回路が構成され、前記触針６が前記電極７，８の何れかに接触することにより通電して、ＮＧ信号を出力する様に構成されている。 Further, a stylus 6 attached to each of the slide bases 5 of the movable support means 2a, 2b, 2d, 2e and one movable support means 2a, 2b, 2d, 2e is mounted. In addition, an energization circuit (not shown) including electrodes 7 and 8 attached to the base 3 and the movable support means 5b and 5d, respectively, is configured, and the stylus 6 contacts either of the electrodes 7 and 8. Is configured to output an NG signal.

即ち、例えば、前記可動支承手段２ａにおいては、前記触針６ａと電極７ａとを接点とする通電回路が形成されると共に、前記触針６ａと電極８ａとを接点とする別の通電回路も形成されている。そして、前記触針６ａが前記電極７ａまたは８ａの何れかに接触することにより通電して、ＮＧ信号を出力する様に構成されている。その他の可動支承手段２ｂ，２ｄ，２ｅにおいても同様に、触針６ｂと電極７ｂまたは８ｂ、触針６ｄと電極７ｄまたは８ｄ及び触針６ｅと電極７ｅまたは８ｅを夫々の接点とする独立した通電回路が形成されている。 That is, for example, in the movable support means 2a, an energization circuit having the contact point between the stylus 6a and the electrode 7a is formed, and another energization circuit having the contact point between the stylus 6a and the electrode 8a is also formed. Has been. The stylus 6a is energized by contacting either the electrode 7a or 8a and outputs an NG signal. Similarly, in the other movable support means 2b, 2d, and 2e, independent energization using the stylus 6b and the electrode 7b or 8b, the stylus 6d and the electrode 7d or 8d, and the stylus 6e and the electrode 7e or 8e as respective contacts is performed. A circuit is formed.

そして、例えば、可動支承手段２ｂにおいて、基準支承部材４ｃの軸心を起点として前記可動支承手段２ｂを基台３上で可動させ、前記基準支承部材４ｃの軸心から支承部材４ｂの軸心までの間隔Ｌ２を、図２に示す如く、前記長尺検査対象体１１におけるＴ字継手１２ｂ，１２ｃ間の間隔の寸法公差における最少寸法（Ｓ２−０）としたとき、前記可動支承手段２ｂの触針６ｂに対応する２本の電極７ｂ，８ｂのうち前記基準支承手段２ｃと反対側の１本、即ち、電極７ｂが前記触針６ｂに接触して通電されるように配設されている。 For example, in the movable support means 2b, the movable support means 2b is moved on the base 3 with the axis of the reference support member 4c as a starting point, and from the axis of the reference support member 4c to the axis of the support member 4b. When the distance L2 is set to the minimum dimension (S2-0) in the dimensional tolerance of the distance between the T-shaped joints 12b and 12c in the long inspection object 11, as shown in FIG. Of the two electrodes 7b, 8b corresponding to the needle 6b, one electrode on the opposite side to the reference support means 2c, that is, the electrode 7b is arranged to come into contact with the stylus 6b and to be energized.

一方、前記基準支承部材４ｃの軸心を起点とし前記可動支承手段２ｂを基台３上で可動させ、前記基準支承部材４ｃの軸心から支承部材４ｂの軸心までの間隔Ｌ２を、図２に示す如く、前記長尺検査対象体１１のＴ字継手１２ｂ，１２ｃ間の間隔の寸法公差における最大寸法（Ｓ２＋Ｃ２）としたとき、前記可動支承手段２ｂの触針６ｂに対応する電極の他の１本、即ち電極８ｂが前記触針６ｂに接触して通電されるように配設されている。 On the other hand, the movable support means 2b is moved on the base 3 starting from the axis of the reference support member 4c, and the distance L2 from the axis of the reference support member 4c to the axis of the support member 4b is shown in FIG. When the maximum dimension (S2 + C2) in the dimensional tolerance of the interval between the T-shaped joints 12b and 12c of the long test object 11 is set as shown in FIG. 2, other electrodes corresponding to the stylus 6b of the movable support means 2b One electrode, that is, the electrode 8b is disposed so as to be in contact with the stylus 6b and energized.

但し、例えば、前記検査対象物１２の間隔Ｌ２の寸法が、１２０±１（ｍｍ）の如く、最少寸法公差がマイナス値で規定される場合は、１１９−０〜１１９＋２（ｍｍ）の如く、前記最少寸法公差が０となる様に書き換えて、前記電極７，８を配設することが肝要である。 However, for example, when the dimension of the interval L2 of the inspection object 12 is 120 ± 1 (mm) and the minimum dimensional tolerance is defined by a negative value, the above-described 119-0 to 119 + 2 (mm) It is important to arrange the electrodes 7 and 8 so that the minimum dimensional tolerance is zero.

そして、前記電極７，８の全数には、特定可能な識別記号、例えば、整数１，２，……やローマ字Ａ，Ｂ，……等が付与されている。そして、前記可動支承手段２ａ，２ｂ，２ｄ，２ｅの各々に取り付けられた触針６が、前記電極７，８の何れかに接触し通電してＮＧ信号を出力する際、何れの検査対象物１２間の間隔の最大寸法、最小寸法のうち、何れの相対位置が不合格かを特定可能な信号を出力可能とされているのが好ましい。即ち、ＮＧが検出された電極７，８に該当する識別記号が付与されたランプを点灯したり、該当する識別記号を表示器に表示したりすることが可能である。 Then, the total number of the electrodes 7 and 8 is given identifiable identification symbols, for example, integers 1, 2,..., Roman letters A, B,. When the stylus 6 attached to each of the movable support means 2a, 2b, 2d, 2e is in contact with any of the electrodes 7, 8 and outputs an NG signal, any inspection object It is preferable that a signal capable of specifying which relative position is unacceptable among the maximum dimension and the minimum dimension of the interval between 12 is output. That is, it is possible to turn on a lamp to which an identification symbol corresponding to the electrodes 7 and 8 in which NG is detected, or to display the corresponding identification symbol on a display.

更に、前記触針６が前記電極７，８の何れにも接触せず、前記ＮＧ信号が出力されない場合は、前記リターンホース１１の何処か、例えば、基準支承手段２ｃに装着されたＴ字継手１２ｄの上面に、自動的に合格マーキングするマーキング装置を備えたものが好ましい。前記マーキング装置としては、刻印装置や印字装置を用いることができる。 Further, when the stylus 6 does not contact any of the electrodes 7 and 8 and the NG signal is not output, somewhere in the return hose 11, for example, a T-shaped joint mounted on the reference support means 2c. What provided the marking apparatus which carries out the automatic marking automatically on the upper surface of 12d is preferable. A marking device or a printing device can be used as the marking device.

以上の通り、本発明に係る検査対象物の相対位置検査方法または装置によれば、この様な相対位置検査装置１において、これら各支承手段２にリターンホース１１の検査対象物であるＬ字継手１２ａ、Ｔ字継手１２ｂ，１２ｃ，１２ｄ及び逆止弁１２ｅを、各支承手段２の支承部材４に夫々装着し、前記可動支承手段２ａ，２ｂ，２ｄ，２ｅの各々に取り付けられた１本の触針６が、基台３及び可動支承手段２ｂ，２ｅの各々に取り付けられた電極７，８の何れかに接触することにより通電してＮＧ信号を出力するか否かを簡便に検査できるのである。 As described above, according to the relative position inspection method or apparatus for an inspection object according to the present invention, in such a relative position inspection apparatus 1, an L-shaped joint that is an inspection object of the return hose 11 is provided in each of the support means 2. 12a, T-shaped joints 12b, 12c, 12d and check valve 12e are mounted on the support member 4 of each support means 2, and are attached to each of the movable support means 2a, 2b, 2d, 2e. Since it is possible to easily check whether the stylus 6 is energized and outputs an NG signal by contacting any of the electrodes 7 and 8 attached to the base 3 and the movable support means 2b and 2e, respectively. is there.

＜実施例＞
今、図２に示したリターンホース１１の構成において、下記の設計寸法を有する長尺検査対称体を考える。そして、Ｌ字継手１２ａを基準として、各検査対象物１２間の間隔の寸法公差の最少値を右方向に順次加算した各継手１２ｂ，１２ｃ，１２ｄもしくは逆止弁１２ｅまでの最少寸法、及び前記寸法公差の最大値を右方向に順次加算した各継手１２ｂ，１２ｃ，１２ｄもしくは逆止弁１２ｅまでの最大寸法が、夫々表１の如く求められる。
Ｓ１＝Ｓ２＝Ｓ３＝１０８ｍｍ，Ｓ４＝１９１ｍｍ，
Ｃ１＝Ｃ２＝Ｃ３＝Ｃ４＝＋２ｍｍ <Example>
Now, in the configuration of the return hose 11 shown in FIG. 2, a long inspection symmetric body having the following design dimensions is considered. Then, with reference to the L-shaped joint 12a, the minimum dimension to the joints 12b, 12c, 12d or the check valve 12e obtained by sequentially adding the minimum value of the dimensional tolerance of the interval between the inspection objects 12 to the right, The maximum dimensions up to the joints 12b, 12c, 12d or the check valve 12e obtained by sequentially adding the maximum dimensional tolerance values in the right direction are obtained as shown in Table 1, respectively.
S1 = S2 = S3 = 108 mm, S4 = 191 mm,
C1 = C2 = C3 = C4 = + 2 mm

そして、実施例においては、図１に示した相対位置検査装置１を用い、前記リターンホース１１のサンプルにおいて、前記Ｔ字継手１２ｃを基準支承手段２ｃの支承部材４ｃに装着して支承させる一方、Ｌ字継手１２ａ、Ｔ字継手１２ｂ，１２ｄと逆止弁１２ｅの各々を、可動支承手段２ａ，２ｂ，２ｄ，２ｅの各支承部材４ａ，４ｂ，４ｄ，４ｅに装着して支承させ、前記リターンホース１１の各検査対象物１２の相対位置を検査した結果、特にＮＧ信号は出力されなかった。その後、このリターンホース１１の各検査対象物１２の間隔Ｌ１〜Ｌ４をノギスにより測定したところ、表１に示す如く、全て寸法公差内にあることが確認された。 In the embodiment, the relative position inspection device 1 shown in FIG. 1 is used, and in the sample of the return hose 11, the T-shaped joint 12c is attached to and supported by the support member 4c of the reference support means 2c. The L-shaped joint 12a, the T-shaped joints 12b, 12d and the check valve 12e are mounted on and supported by the respective support members 4a, 4b, 4d, 4e of the movable support means 2a, 2b, 2d, 2e. As a result of inspecting the relative position of each inspection object 12 of the hose 11, no NG signal was particularly output. Thereafter, when the distances L1 to L4 between the inspection objects 12 of the return hose 11 were measured with a caliper, as shown in Table 1, it was confirmed that they were all within dimensional tolerances.

一方、比較例における相対位置検査装置として、前記Ｌ字継手１２ａを支承する支承部材４ａを基台３に固定した図示しない基準支承手段とする一方、Ｔ字継手１２ｂ，１２ｃ，１２ｄと逆止弁１２ｅの各々を支承する各支承手段を、基台３上にのみ相対移動可能に搭載された図示しない可動支承手段として構成した。そして、前記リターンホース１１と同一の構成を有する他のサンプルを用いて、各検査対象物１２を前記支承手段に装着して支承させ、前記検査対象物１２の相対位置を検査した結果、特にＮＧ信号は出力されなかった。 On the other hand, as a relative position inspection device in the comparative example, the support member 4a for supporting the L-shaped joint 12a is used as a reference support means (not shown) fixed to the base 3, while the T-shaped joints 12b, 12c, 12d and the check valve Each support means for supporting each of 12e was configured as a movable support means (not shown) mounted on the base 3 so as to be relatively movable. Then, using another sample having the same configuration as that of the return hose 11, each inspection object 12 is mounted on and supported by the support means, and the relative position of the inspection object 12 is inspected. No signal was output.

その後、このリターンホースサンプルの各検査対象物１２の間隔Ｌ１〜Ｌ４をノギスにより測定したところ、表１に示す如く、間隔Ｌ２，Ｌ３，Ｌ４が寸法公差外にあることが判明した。この原因は、検査対象物１２の各可動支承手段を基台３上のみ相対移動可能に搭載して構成したため、各間隔Ｌ１〜Ｌ４が各検査対象物１２の相対位置とならないことに起因している。 Thereafter, when the distances L1 to L4 of each inspection object 12 of the return hose sample were measured with a caliper, it was found that the distances L2, L3, and L4 were outside the dimensional tolerances as shown in Table 1. This is because each movable support means of the inspection object 12 is mounted so as to be relatively movable only on the base 3, and therefore, the intervals L1 to L4 are not relative positions of the inspection objects 12. Yes.

以上説明した通り、本発明に係る検査対象物の相対位置検査方法または装置によれば、検査対象物を支承する支承手段と、これらの支承手段を直接または間接的に搭載する基台とを備えると共に、前記の支承手段が、前記基台に固定された基準支承手段と、この基準支承手段に隣接する前記検査対象物を夫々支承し、前記基台上に相対移動可能に搭載された可動支承手段と、前記可動支承手段の次に隣接する前記検査対象物を夫々支承し、前記可動支承手段に相対移動可能に順次繰り返し積層された可動支承手段とからなる。 As described above, according to the relative position inspection method or apparatus for an inspection object according to the present invention, the support means for supporting the inspection object and the base for directly or indirectly mounting these support means are provided. In addition, the support means supports the reference support means fixed to the base and the inspection object adjacent to the reference support means, and the movable support is mounted on the base so as to be relatively movable. And movable support means that successively supports the object to be inspected next to the movable support means, and is sequentially and repeatedly stacked on the movable support means so as to be relatively movable.

そして一方、前記可動支承手段の各々に取り付けられた１本の触針と、これらの可動支承手段が搭載された基台及び可動支承手段の各々に取り付けられた電極とを含む通電回路が夫々構成され、前記触針が前記電極の何れかに接触することにより通電して、ＮＧ信号を出力する様に構成されたので、長尺検査対象体の検査対象物を前記支承手段に装着することによって、複数個の前記検査対象物の相対位置を瞬時に検査可能である。 On the other hand, each energizing circuit includes one stylus attached to each of the movable support means, a base on which these movable support means are mounted, and an electrode attached to each of the movable support means. Since the stylus is energized by contacting any of the electrodes and outputs an NG signal, the inspection object of the long inspection object is attached to the support means. The relative positions of the plurality of inspection objects can be instantaneously inspected.
