Yes.

詳細には、サイドメンバの両外側に矢倉状フレーム体を立設すると共に、当該フレーム体により左右両端を支持される梁状の治具を、ルーフパネル上を横断するように当該フレーム上に配置する。そして、梁状治具に取付けた左右一対のクランプ治具でサイドメンバの上位溶接縁の前部とルーフの左右溶接縁の前部、および、サイドメンバの上位溶接縁の後部とルーフパネルの左右溶接縁の後部とを連結固定し、この連結状態でサイドメンバとルーフパネルとを仮付けする手段が開示されている。

JP 2003-146261 A

ところで、最近では、多様なニーズに応えるため、１つの製造ラインにつき複数の車種を対応させる必要性が増しており、これら多品種生産に適した製造ラインの整備が重要となっている。また、省エネルギー化の観点からも製造ラインの小型化は重要な課題となっている。   Recently, in order to respond to various needs, there is an increasing need to support a plurality of vehicle types per production line, and it is important to establish a production line suitable for production of these various products. In addition, downsizing of the production line is an important issue from the viewpoint of energy saving.

上記観点から、従来の仮付け方法を省みると、例えば特許文献１に開示の手段では、矢倉状フレーム等の位置決め専用設備が大型化するため、多大な設置スペースが必要となることがわかる。また、車種ごとにルーフパネルの車幅寸法が異なり、個別に専用の位置決め治具（クランプ治具）が必要となるため、これら専用の治具を保管しておくスペースが必要となる。もちろん、車種の分だけ専用の治具が必要なことから、多車種に対応するため多額の初期設備投資が必要となる。   From the above viewpoint, if a conventional tacking method is omitted, it can be seen that, for example, the means disclosed in Patent Document 1 requires a large installation space because the positioning dedicated equipment such as the arrow-shaped frame is enlarged. In addition, the vehicle width dimension of the roof panel is different for each vehicle type, and a dedicated positioning jig (clamp jig) is required individually. Therefore, a space for storing these dedicated jigs is required. Of course, since dedicated jigs are required for the number of vehicle types, a large amount of initial capital investment is required in order to support multiple vehicle types.

以上の事情に鑑み、本発明では、車体の仮付け時、車種に関らず車体部品の位置決めを高精度に行うことができ、かつ、位置決めに要する設備もしくはその保管スペースを低減することで設備投資の低廉化を図ることのできる車体部品の位置決め装置、および、位置決め方法を提供することを技術的課題とする。   In view of the above circumstances, in the present invention, when temporarily attaching a vehicle body, positioning of vehicle body parts can be performed with high accuracy regardless of the type of vehicle, and equipment required for positioning or reducing the storage space thereof can be provided. An object of the present invention is to provide a positioning device for a vehicle body part and a positioning method capable of reducing the investment.

前記課題を解決するため、本発明は、相互に重ね合わせたルーフパネルと左右のサイドメンバとの溶接縁部を溶接する際、ルーフパネルおよび左右のサイドメンバの位置決めを行う車体部品の位置決め装置であって、溶接縁部に形成される左右の溝部にそれぞれ挿入可能な一対の挿入部を備え、一対の挿入部はそれぞれ、溝部に挿入し共に車幅方向外側に移動することによりサイドメンバの内側面に当接する第１当接部と、溝部に挿入し共に車幅方向内側に移動することによりルーフパネルの外側面に当接する第２当接部とを有し、第１当接部間の離間距離と第２当接部間の離間距離とは共に可変で、かつ、それぞれ所定の大きさに設定可能とされている車体部品の位置決め装置を提供する。   In order to solve the above-described problems, the present invention provides a positioning device for a vehicle body part that positions a roof panel and left and right side members when welding welded edges of a roof panel and left and right side members that are overlapped with each other. A pair of insertion portions that can be respectively inserted into the left and right groove portions formed in the welded edge portion, and the pair of insertion portions are inserted into the groove portions and moved to the outside in the vehicle width direction. A first abutting portion that abuts against the side surface, and a second abutting portion that abuts against the outer surface of the roof panel by being inserted into the groove and moving inward in the vehicle width direction. Provided is a vehicle body part positioning apparatus in which both the separation distance and the separation distance between second contact portions are variable and can be set to predetermined sizes.

本発明は、仮付け時におけるサイドメンバの姿勢に着目して創出されたものである。すなわち、サイドメンバは、通常、鉛直方向よりも内側に傾いた姿勢で完成車体の外側面を構成することから、組付け時、その上部が自重により内側へたわむ、あるいは若干倒れ込むことがある。本発明はこの点に着目しなされたもので、上記構成によれば、左右の溝部にそれぞれ挿入された各挿入部の第１当接部間の離間距離を所定の距離に設定することで、サイドメンバが正規位置より内側に傾いている場合、左右の第１当接部がそれぞれ対応するサイドメンバの内側面を外側に向けて押す。これにより、サイドメンバの内側面間の離間距離（ピッチ）が所定の距離に設定され、サイドメンバ上部の水平方向への位置決めがなされる。また、左右の溝部に挿入された第２当接部間の離間距離を所定の距離に設定することで、左右の第２当接部の一方もしくは双方がルーフパネルの外側面を押す。これにより、ルーフパネルが車幅方向に移動し、サイドメンバに対するルーフパネルの位置決めがなされる。   The present invention was created by paying attention to the posture of the side member at the time of tacking. That is, since the side member normally constitutes the outer surface of the completed vehicle body in a posture inclined inward from the vertical direction, the upper part of the side member may be bent inward or slightly fall down due to its own weight when assembled. The present invention has been made paying attention to this point, and according to the above configuration, by setting the separation distance between the first contact portions of the respective insertion portions respectively inserted into the left and right groove portions to a predetermined distance, When the side member is inclined inward from the normal position, the left and right first abutting portions respectively push the inner side surfaces of the corresponding side members outward. Thereby, the separation distance (pitch) between the inner side surfaces of the side members is set to a predetermined distance, and the positioning of the upper side members in the horizontal direction is performed. Further, by setting the separation distance between the second contact portions inserted in the left and right groove portions to a predetermined distance, one or both of the left and right second contact portions press the outer surface of the roof panel. As a result, the roof panel moves in the vehicle width direction, and the roof panel is positioned with respect to the side member.

このように、車体部品と当接する各当接部間の離間距離（ピッチ）を可変とすることで、これら当接部と当接する左右のサイドメンバ間のピッチ、および、左右のサイドメンバに対するルーフパネルの位置決めを車種ごとに的確に行うことができる。よって、従来のように、車種ごとの専用治具やこれら治具を載置するための大掛かりな設備（矢倉状フレームなど）が不要となる。また、車種変更の際も、各当接部間の離間距離（ピッチ）を変更するだけで対応でき、車種ごとに専用の治具を準備する必要もないため、設備コストの低廉化が可能となる。もちろん、これら専用治具を保管するスペースも不要となるため、この分の設備スペースや作業スペースをさらに確保できる。   In this way, by making the separation distance (pitch) between the contact portions that contact the vehicle body parts variable, the pitch between the left and right side members that contact the contact portions, and the roof for the left and right side members The panel can be accurately positioned for each vehicle type. Therefore, as in the prior art, a dedicated jig for each vehicle type and large-scale equipment (such as a Yakura frame) for mounting these jigs are not required. In addition, when changing the vehicle type, it is possible to respond by simply changing the separation distance (pitch) between the contact parts, and it is not necessary to prepare a dedicated jig for each vehicle type, so the equipment cost can be reduced. Become. Of course, since the space for storing these dedicated jigs is not required, it is possible to further secure the equipment space and work space for this.

また、本発明に係る位置決め装置であれば、サイドメンバ間のピッチが常に正確に設定されることから、ルーフパネルの車幅寸法のばらつきを溝部の車幅寸法で吸収することができる。従い、反り度合い等によりルーフパネルの車幅寸法がばらつく場合であっても、各サイドメンバ上部における車幅方向の位置決め、および、左右のサイドメンバに対するルーフパネルの位置決めを高精度に行うことができる。   Further, in the positioning device according to the present invention, since the pitch between the side members is always set accurately, the variation in the vehicle width dimension of the roof panel can be absorbed by the vehicle width dimension of the groove portion. Therefore, even when the vehicle width dimension of the roof panel varies due to the degree of warpage or the like, the positioning in the vehicle width direction at the top of each side member and the positioning of the roof panel with respect to the left and right side members can be performed with high accuracy. .

また、この場合、サイドメンバの外側に、サイドメンバの外面と当接し、この外面を所定の車幅方向位置で押える押え手段をさらに有する構成とすることもできる。この構成によれば、サイドメンバの上部が正規位置より外側に傾いた場合であっても、サイドメンバを正規の車幅方向位置にて位置決めすることができる。特に、フロアパネルとサイドメンバ、サイドメンバとルーフパネルとを一体に仮組みした状態で１度に仮打ち溶接する場合など、サイドメンバの姿勢が不安定となる溶接態様の場合に有効である。また、別々の機構でサイドメンバの内側面および外面を押えるようにしたので、外側に配置される押え手段は他の作業を兼用することもできる。押え手段が押え専用の治具だとしても、押え部分を車幅方向にのみ移動させれば足りるためその構造は単純なもので済む。   In this case, it is also possible to have a structure further including a pressing means that contacts the outer surface of the side member on the outside of the side member and presses the outer surface at a predetermined position in the vehicle width direction. According to this configuration, even when the upper part of the side member is inclined outward from the normal position, the side member can be positioned at the normal vehicle width direction position. In particular, it is effective in the case of a welding mode in which the posture of the side member becomes unstable, such as when temporary welding is performed once in a state where the floor panel and the side member and the side member and the roof panel are temporarily assembled together. Further, since the inner surface and the outer surface of the side member are pressed by separate mechanisms, the pressing means arranged on the outside can also be used for other operations. Even if the presser means is a jig dedicated to the presser, it is sufficient to move the presser part only in the vehicle width direction, so that the structure is simple.

また、前記課題を解決するため、本発明は、相互に重ね合わせたルーフパネルと左右のサイドメンバとの溶接縁部を溶接する際、ルーフパネルおよび左右のサイドメンバの位置決めを行う車体部品の位置決め方法であって、溶接縁部に形成される左右の溝部に一対の第１挿入部をそれぞれ挿入し、互いに離反する向きに移動させることで左右のサイドメンバを共に外側に押し拡げ、左右のサイドメンバ間の離間距離を設定し、左右の溝部に一対の第２挿入部をそれぞれ挿入し、互いに近接する向きに移動させることでルーフパネルを車幅方向に押し動かし、ルーフパネルの車幅方向位置を設定する車体部品の位置決め方法を提供する。   In order to solve the above-mentioned problems, the present invention is directed to positioning a vehicle body part that positions the roof panel and the left and right side members when welding the welded edges of the roof panel and the left and right side members that are overlapped with each other. In this method, a pair of first insertion portions are respectively inserted into the left and right groove portions formed in the welded edge portions, and moved in directions away from each other, so that the left and right side members are both pushed outward and expanded to the left and right sides. Set the separation distance between the members, insert the pair of second insertion parts into the left and right groove parts respectively, and move the roof panel in the vehicle width direction by moving it in the direction approaching each other. A vehicle body part positioning method for setting

この方法によれば、各挿入部の挿入動作、および、車幅方向への移動のみをもってサイドメンバとルーフパネルの位置決めが可能となる。そのため、挿入部の車幅方向への移動精度さえ確保できれば、互いに車幅の異なる複数の車種が混合する製造ラインであっても、車種ごとに適切な離間距離を設定して、サイドメンバの車幅方向の位置決めを正確に行うことができる。また、挿入部は溝部に挿入できる程度の大きさで済み、かつ、その際に必要な移動機構は車幅方向に沿った移動のみの機構で足りる。これにより、挿入部全体のサイズを小さくして、その慣性を小さくすることができるので、挿入部の車幅方向への移動を高精度に行うことができる。逆にいえば、この挿入部を移動させるのにそれほど高精度な駆動機構（マニピュレータなど）は必要ないため、当該駆動機構に関しても小型化が可能となる。   According to this method, the side member and the roof panel can be positioned only by the insertion operation of each insertion portion and the movement in the vehicle width direction. Therefore, as long as the moving accuracy of the insertion portion in the vehicle width direction can be ensured, an appropriate separation distance is set for each vehicle type even on a production line in which a plurality of vehicle types having different vehicle widths are mixed with each other. Positioning in the width direction can be performed accurately. Further, the insertion portion may be of a size that can be inserted into the groove portion, and a moving mechanism required at that time may be a mechanism that only moves along the vehicle width direction. Thereby, since the size of the whole insertion portion can be reduced and the inertia thereof can be reduced, the insertion portion can be moved in the vehicle width direction with high accuracy. Conversely, since a drive mechanism (manipulator or the like) with such high accuracy is not required to move the insertion portion, the drive mechanism can be downsized.

以上のように、本発明に係る車体部品の位置決め装置もしくは位置決め方法によれば、車体の仮付け時、車種に関らず車体部品の位置決めを高精度に行うことができ、かつ、位置決めに要する設備もしくはその保管スペースを低減することで設備投資の低廉化を図ることができる。   As described above, according to the positioning device or positioning method for a vehicle body part according to the present invention, it is possible to position the vehicle body part with high accuracy regardless of the type of the vehicle when temporarily attaching the vehicle body, and it is necessary for the positioning. By reducing the equipment or its storage space, the capital investment can be reduced.

以下、本発明に係る車体部品の位置決め装置、および、車体部品の位置決め方法の一実施形態を図面に基づき説明する。   Hereinafter, an embodiment of a positioning device for a vehicle body part and a positioning method for a vehicle body part according to the present invention will be described with reference to the drawings.

図１は、車体溶接ライン１における溶接工程の流れを概念的に示す図である。同図に係る溶接工程は、ワーク仮組ステーションＳ１上で実施される車体２の仮組工程、ワーク仮打ちステーションＳ２上で実施される車体２の仮打ち工程、および、ワーク増打ちステーションＳ３上で実施される車体２の増打ち工程とを有する。以下、この溶接工程を、ワーク仮打ちステーションＳ２上における仮打ち工程を中心に説明する。   FIG. 1 is a diagram conceptually showing a flow of a welding process in the vehicle body welding line 1. The welding process shown in the figure includes a temporary assembly process for the vehicle body 2 performed on the workpiece temporary assembly station S1, a temporary assembly process for the vehicle body 2 performed on the workpiece temporary assembly station S2, and a workpiece additional application station S3. And the step of increasing the number of hits of the vehicle body 2. Hereinafter, this welding process will be described with a focus on the temporary placing process on the work temporary placing station S2.

まず、予め複数の構成部品を溶接等により一体化してなるフロアパネル５が搬送ライン３上をワーク仮組ステーションＳ１に向けて搬送される。ここでは、各搬送ライン３上にワーク搬送用パレット４が配置されており、予め一体化されているフロアパネル５はこのワーク搬送用パレット４上に載置された状態でワーク仮組ステーションＳ１上にまで搬送される。   First, a floor panel 5 formed by integrating a plurality of components in advance by welding or the like is transported on the transport line 3 toward the work temporary assembly station S1. Here, a workpiece transfer pallet 4 is arranged on each transfer line 3, and the floor panel 5 integrated in advance is placed on the workpiece transfer pallet 4 on the workpiece temporary assembly station S 1. It is conveyed to.

そして、ワーク仮組ステーションＳ１上に搬送されたフロアパネル５上に、対応する左右のサイドメンバ６，６が例えば図２に示すような態様で載置されると共に、適当な仮止め手段により各サイドメンバ６，６とフロアパネル５との間で仮止めがなされる。なお、図２では、左右一方のサイドメンバ６をフロアパネル５上に仮組みした後、他方のサイドメンバ６を仮組みする場合を概念的に示しているが、双方のサイドメンバ６，６を同時にフロアパネル５に対して仮組みすることができることはもちろんである。   Then, the corresponding left and right side members 6 and 6 are placed on the floor panel 5 conveyed onto the work temporary assembly station S1, for example, as shown in FIG. Temporary fixing is performed between the side members 6 and 6 and the floor panel 5. FIG. 2 conceptually shows a case where the left and right side members 6 are temporarily assembled on the floor panel 5 and then the other side member 6 is temporarily assembled. Needless to say, the floor panel 5 can be temporarily assembled at the same time.

このようにして両サイドメンバ６，６のフロアパネル５に対する仮組みがなされた後、双方のサイドメンバ６，６上に、これら双方のサイドメンバ６，６上に跨る形でルーフパネル７が載置される。これにより、フロアパネル５と左右のサイドメンバ６，６、および、ルーフパネル７とが一体に仮組みされた状態の車体２が形成される。   After the side members 6 and 6 are temporarily assembled to the floor panel 5 in this way, the roof panel 7 is mounted on both the side members 6 and 6 so as to straddle both the side members 6 and 6. Placed. Thereby, the vehicle body 2 in a state where the floor panel 5, the left and right side members 6, 6 and the roof panel 7 are temporarily assembled together is formed.

次に、仮組みされた状態の車体２がワーク搬送用パレット４を介して搬送ライン３上を搬送され、ワーク仮打ちステーションＳ２上の所定位置にて車体２が停止した状態で、各車体部品の位置決めおよび仮打ち溶接が実施される。   Next, the vehicle body 2 in the temporarily assembled state is conveyed on the conveyance line 3 via the workpiece conveyance pallet 4, and the vehicle body 2 is stopped at a predetermined position on the workpiece temporary placing station S2. Positioning and temporary welding are performed.

ここで、各車体部品の位置決めは、例えば図３に示すように複数箇所の位置決め基準に基づき実施される。詳細には、図３および図４に示すように、各サイドメンバ６の上縁部とルーフパネル７の左右縁部との重合部に形成される左右の溝部８，８内に、サイドメンバ６，６の車幅方向（図３中矢印Ｗで示す方向）の位置決めのための位置決め基準Ｌ１，Ｌ２が設けられる。また、同じく左右の溝部８，８内に、ルーフパネル７の車幅方向の位置決め基準Ｌ３，Ｌ４が設けられる。この他、図示は省略するが、各サイドメンバ６，６には、各サイドメンバ６，６の車体前後方向（図３中矢印Ｌで示す方向）の位置決め基準や、上下方向（図３中矢印Ｈで示す方向）の位置決め基準が設けられる。この際、サイドメンバ６，６の大きさ、形状を考慮して、上述の各位置決め基準を複数箇所に設けることも可能である。また、ルーフパネル７に、ルーフパネル７の車体前後方向もしくは上下方向の位置決め基準を設けることも可能である。   Here, the positioning of each vehicle body part is performed based on a plurality of positioning standards as shown in FIG. 3, for example. Specifically, as shown in FIGS. 3 and 4, the side members 6 are placed in the left and right groove portions 8 and 8 formed at the overlapping portion of the upper edge portion of each side member 6 and the left and right edge portions of the roof panel 7. 6, positioning references L1 and L2 for positioning in the vehicle width direction (the direction indicated by the arrow W in FIG. 3) are provided. Similarly, positioning references L3 and L4 in the vehicle width direction of the roof panel 7 are provided in the left and right groove portions 8 and 8, respectively. In addition, although not shown, each side member 6, 6 has a positioning reference in the longitudinal direction of the vehicle body (direction indicated by arrow L in FIG. 3) and the vertical direction (arrow in FIG. 3). A positioning reference in the direction indicated by H) is provided. At this time, in consideration of the size and shape of the side members 6 and 6, it is possible to provide the above-mentioned positioning references at a plurality of locations. Further, the roof panel 7 can be provided with a positioning reference for the roof panel 7 in the longitudinal direction or the vertical direction of the vehicle body.

また、各サイドメンバ６，６の前後方向中央の上部、ここでは、位置決め基準Ｌ１，Ｌ２の近傍に、それぞれ各サイドメンバ６，６の上部における車幅方向の位置決め基準Ｔ１，Ｔ２が設けられる。   Further, positioning references T1 and T2 in the vehicle width direction at the upper portions of the side members 6 and 6 and in the vicinity of the positioning references L1 and L2, respectively, in the vicinity of the positioning references L1 and L2, respectively.

次に、位置決め基準Ｌ１〜Ｌ４におけるサイドメンバ６，６およびルーフパネル７の位置決め方法について説明する。   Next, the positioning method of the side members 6 and 6 and the roof panel 7 in the positioning references L1 to L4 will be described.

図４（ａ）は、上記位置決め方法に使用される位置決め装置１０の正面図を示している。同図に示すように、この位置決め装置１０は、大きく分けて駆動部１１と、駆動部１１により所定の動作に制御駆動され、各サイドメンバ６，６およびルーフパネル７に対して直接的に位置決め作用を及ぼすための位置決め本体１２とからなる。駆動部１１は、傾動、回転、伸縮可能な関節構造を有するマニピュレータ１３を主要部としている。位置決め本体１２はマニピュレータ１３の先端に取付けられ、三次元移動が可能となるように構成される。   Fig.4 (a) has shown the front view of the positioning device 10 used for the said positioning method. As shown in the figure, the positioning device 10 is roughly divided into a drive unit 11 and a predetermined operation controlled by the drive unit 11 to directly position the side members 6 and 6 and the roof panel 7. It comprises a positioning body 12 for exerting an action. The drive unit 11 includes a manipulator 13 having a joint structure that can tilt, rotate, and expand / contract as a main part. The positioning body 12 is attached to the tip of the manipulator 13 and is configured to be capable of three-dimensional movement.

また、この実施形態では、図６に例示の如く、各サイドメンバ６，６の両外側に、サイドメンバ６，６の外面と当接可能で、かつ、この外面を所定に車幅方向位置で押えることのできる押え手段２０，２０がそれぞれ設けられている。この場合、これら押え手段２０，２０により位置決めされる箇所が、図３に示す各サイドメンバ６，６外面の位置決め基準Ｔ１，Ｔ２に対応する位置となる。   Further, in this embodiment, as illustrated in FIG. 6, the outer surfaces of the side members 6 and 6 can be brought into contact with the outer surfaces of the side members 6 and 6, and the outer surfaces are at predetermined positions in the vehicle width direction. Presser means 20 and 20 that can be pressed are provided. In this case, the positions positioned by the presser means 20 and 20 are positions corresponding to the positioning references T1 and T2 of the outer surfaces of the side members 6 and 6 shown in FIG.

上記構成の位置決め装置１０を用いた、サイドメンバ６，６およびルーフパネル７の位置決め方法の一例を図５〜図７に基づき説明する。   An example of a method for positioning the side members 6 and 6 and the roof panel 7 using the positioning device 10 having the above configuration will be described with reference to FIGS.

まず、位置決め本体１２を駆動部１１によりルーフパネル７の上方に移動させると共に、位置決め本体１２に設けた一方の第１スライド部１６の第１当接部１８を、図５に示すように、対応する一方の溝部８の上方に配置する（図５中１点鎖線で示す位置）。また、図示は省略するが、他方の第１当接部１８も対応する他方の溝部８の上方に配置する。そして、この状態から位置決め本体１２を下降させることで、左右の第１当接部１８，１８を溝部８，８内の前後方向所定位置、図３でいうと位置決め基準Ｌ１，Ｌ２に対応する位置にそれぞれ挿入する。同様に、位置決め本体１２を下降させることで、左右の第２当接部１９，１９を溝部８，８内の前後方向所定位置、図３でいうと位置決め基準Ｌ３，Ｌ４に対応する位置にそれぞれ挿入する。   First, the positioning body 12 is moved above the roof panel 7 by the drive unit 11, and the first abutting portion 18 of one first slide portion 16 provided in the positioning body 12 is adapted as shown in FIG. It arrange | positions above the one groove part 8 to perform (position shown with a dashed-dotted line in FIG. 5). Although not shown, the other first contact portion 18 is also disposed above the corresponding other groove portion 8. Then, by lowering the positioning main body 12 from this state, the left and right first abutting portions 18 and 18 are positioned at predetermined positions in the front and rear direction in the groove portions 8 and 8, that is, positions corresponding to the positioning references L1 and L2 in FIG. Insert into each. Similarly, by lowering the positioning body 12, the left and right second contact portions 19 and 19 are respectively positioned at predetermined positions in the front and rear direction in the groove portions 8 and 8, that is, positions corresponding to the positioning references L3 and L4 in FIG. insert.

そして、図６に示すように、左右の溝部８，８内の所定位置に挿入した状態の第１当接部１８，１８間の離間距離が狙いとする距離Ｗ１になるまでこれら第１当接部１８，１８を互いに離反する向きに移動させる。これにより、溝部８，８を形成するサイドメンバ６，６の内側面６ａ，６ａと第１当接部１８，１８とが当接し、サイドメンバ６，６が正規位置より車体内側に傾いている場合には、第１当接部１８，１８が、内側面６ａ，６ａ間の離間距離（ピッチ）が距離Ｗ１となるまでサイドメンバ６，６を共に車体外側に向けて押す。以上の第１当接部１８，１８による位置決め動作により、サイドメンバ６，６上部における車幅方向の位置決めがなされる。   Then, as shown in FIG. 6, these first abutments until the separation distance between the first abutment portions 18, 18 inserted at predetermined positions in the left and right groove portions 8, 8 reaches the target distance W <b> 1. The parts 18, 18 are moved away from each other. As a result, the inner side surfaces 6a, 6a of the side members 6, 6 forming the groove portions 8, 8 are in contact with the first contact portions 18, 18, and the side members 6, 6 are tilted to the inside of the vehicle body from the normal position. In this case, the first abutting portions 18 and 18 push the side members 6 and 6 toward the outside of the vehicle body until the distance (pitch) between the inner side surfaces 6a and 6a becomes the distance W1. Positioning in the vehicle width direction on the side members 6 and 6 is performed by the positioning operation by the first contact portions 18 and 18 described above.

また、図７に示すように、左右の溝部８，８内の所定位置に挿入した状態の第２当接部１９，１９を互いに近接する向きに移動させる。この際、第２当接部１９，１９間の車幅方向中央位置がルーフパネル７を狙いとする車幅方向位置においた場合の車幅方向中央位置と一致するよう第２当接部１９，１９を移動させる。これにより、内側面６ａ，６ａと共に溝部８，８を形成するルーフパネル７の外側面７ａ，７ａの一方と対応する側の第２当接部１９とが当接し、当接側からルーフパネル７を狙いとする車幅方向位置に向けて押す。以上の第２当接部１９，１９による位置決め動作により、ルーフパネル７のサイドメンバ６，６に対する車幅方向の位置決めがなされる。   Moreover, as shown in FIG. 7, the 2nd contact parts 19 and 19 of the state inserted in the predetermined position in the right-and-left groove parts 8 and 8 are moved to the direction which adjoins mutually. At this time, the second contact portion 19, 19 is arranged so that the center position in the vehicle width direction between the second contact portions 19, 19 matches the center position in the vehicle width direction when the roof panel 7 is aimed at the vehicle width direction position. 19 is moved. As a result, the second abutting portion 19 on the side corresponding to one of the outer side surfaces 7a, 7a of the roof panel 7 which forms the groove portions 8, 8 together with the inner side surfaces 6a, 6a abuts, and the roof panel 7 from the abutting side contacts. Push toward the position in the vehicle width direction aiming at. Positioning in the vehicle width direction with respect to the side members 6 and 6 of the roof panel 7 is performed by the positioning operation by the second contact portions 19 and 19 described above.

そして、他の位置決め基準においても適当なＮＣ装置や溶接ロボット、あるいはクランプ部材により、サイドメンバ６，６やルーフパネル７の位置決めがなされた状態で、所定の箇所にスポット溶接により仮打ちが実施される。これにより、相互に仮組みされた状態のフロアパネル５と左右のサイドメンバ６，６、および、左右のサイドメンバ６，６とルーフパネル７とがそれぞれ溶接部を介して一体に連結固定される。そして、さらに搬送方向前方に位置するワーク増打ちステーションＳ３上にて増打ちがなされ、車体２のアセンブリが完了する。   Also, with other positioning standards, temporary placement is performed by spot welding at a predetermined position in a state where the side members 6 and 6 and the roof panel 7 are positioned by an appropriate NC device, a welding robot, or a clamp member. The As a result, the floor panel 5 and the left and right side members 6 and 6 that are temporarily assembled with each other, and the left and right side members 6 and 6 and the roof panel 7 are integrally connected and fixed via the welded portions. . Further, the additional hitting is performed on the workpiece boosting station S3 located in front of the conveying direction, and the assembly of the vehicle body 2 is completed.

このように、上記位置決め方法によれば、各第１当接部１８，１８の溝部８，８への挿入動作、および、車幅方向外側への移動のみをもってサイドメンバ６，６上部における車幅方向の位置決めが可能になる。また、第２当接部１９，１９の溝部８，８への挿入動作、および、車幅方向内側への移動のみをもってルーフパネル７の車幅方向の位置決めが可能となる。そのため、位置決め本体１２の車幅方向の位置精度さえ確保できれば、互いに車幅の異なる複数種の車体２が混合する製造ラインであっても、車種ごとに適切な離間距離Ｗ１を設定して、サイドメンバ６，６の位置決めを正確に行うことができる。この場合、車種ごとの専用治具やこれら治具を載置するための大掛かりな設備が不要となるため、設備コストの低廉化が可能となる。もちろん、これら専用治具を保管するスペースも不要となるため、この分の設備スペースや作業スペースを確保できる。   Thus, according to the positioning method described above, the vehicle width at the upper part of the side members 6 and 6 can be obtained only by inserting the first contact portions 18 and 18 into the grooves 8 and 8 and moving outward in the vehicle width direction. Directional positioning is possible. Further, the roof panel 7 can be positioned in the vehicle width direction only by the insertion operation of the second contact portions 19 and 19 into the grooves 8 and 8 and the movement inward in the vehicle width direction. Therefore, as long as the positioning accuracy of the positioning body 12 in the vehicle width direction can be ensured, an appropriate separation distance W1 is set for each vehicle type even in a production line in which a plurality of types of vehicle bodies 2 having different vehicle widths are mixed. The members 6 and 6 can be accurately positioned. In this case, a dedicated jig for each vehicle type and a large-scale facility for mounting these jigs are not required, so that the facility cost can be reduced. Of course, since the space for storing these dedicated jigs is not required, the equipment space and work space can be secured.

また、この実施形態では、位置決め本体１２に関し、スライド部１６，１７を介して第１当接部１８，１８および第２当接部１９，１９がレール部１５上を車幅方向にスライド可能な構成としたので、双方の当接部１８，１９を位置決め本体１２に集約することができる。そのため、位置決め本体１２を駆動制御するマニピュレータ１３（駆動部１１）も１体で済み、設備スペースの大幅な節約が可能となる。また、ピン当接でもってサイドメンバ６，６やルーフパネル７の位置決めが可能となることから、必要となる動力が小さくて済み、かつ、位置決め本体１２全体も小さくできるのでこれを駆動するための駆動部１１も小型化できる。   Further, in this embodiment, with respect to the positioning main body 12, the first contact portions 18 and 18 and the second contact portions 19 and 19 can slide on the rail portion 15 in the vehicle width direction via the slide portions 16 and 17. Since it was set as the structure, both the contact parts 18 and 19 can be integrated in the positioning main body 12. FIG. Therefore, only one manipulator 13 (drive unit 11) for driving and controlling the positioning main body 12 is required, and the equipment space can be greatly saved. Further, since the side members 6 and 6 and the roof panel 7 can be positioned by the pin contact, the required power is small and the positioning body 12 as a whole can be made small. The drive unit 11 can also be reduced in size.

また、この実施形態では、サイドメンバ６，６の両外側に、サイドメンバの外面と当接し、この外面を所定の車幅方向位置で押える押え手段２０をそれぞれ配して、位置決め基準Ｔ１，Ｔ２において、各サイドメンバ６，６の外面を押えるようにした。この場合、各サイドメンバ６，６の上部における水平方向の位置決めは、実質的に第１当接部１８，１８と押え手段２０，２０とにより実施されることになる。そのため、サイドメンバ６，６の上部が正規位置より車体外側に傾いて仮組みされた状態であっても、サイドメンバ６，６の上部を正規の車幅方向位置に設定することができる。また、車体２（サイドメンバ６）の外側に配置された押え手段２０は、溝部８内に挿入された第１当接部１８と異なり、高い自由度をもって移動可能である。従い、位置決め基準Ｌ１，Ｌ２や位置決め基準Ｔ１，Ｔ２にてサイドメンバ６，６を所定位置に位置決めした状態で各基準の近傍を溶接した後であれば、押え手段２０による押えポイントを変更することも可能である。例えば、溶接順に従い、サイドメンバ６の外面における溶接箇所の近傍を押え手段２０で順に押えるようにその押えポイントを移動させていくことで、溶接時の位置精度を高めることができる。   In this embodiment, the pressing means 20 that contacts the outer surface of the side member and presses the outer surface at a predetermined position in the vehicle width direction is disposed on both outer sides of the side members 6 and 6, respectively. The outer surfaces of the side members 6 and 6 are pressed. In this case, the horizontal positioning of the upper portions of the side members 6 and 6 is substantially performed by the first contact portions 18 and 18 and the pressing means 20 and 20. Therefore, even if the upper parts of the side members 6 and 6 are temporarily assembled to the outside of the vehicle body from the normal position, the upper parts of the side members 6 and 6 can be set to the normal vehicle width direction position. Further, unlike the first contact portion 18 inserted into the groove portion 8, the presser means 20 disposed outside the vehicle body 2 (side member 6) can move with a high degree of freedom. Therefore, if the vicinity of each reference is welded in a state where the side members 6 and 6 are positioned at predetermined positions based on the positioning references L1 and L2 and the positioning references T1 and T2, the presser point by the presser 20 is changed. Is also possible. For example, the position accuracy at the time of welding can be improved by moving the pressing point so that the vicinity of the welded portion on the outer surface of the side member 6 is sequentially pressed by the pressing means 20 according to the welding order.

以上、仮打ち工程における車体部品の位置決め方法の一実施形態につき説明したが、当該位置決め方法および位置決め装置１０は、上記実施形態に限定されることなく種々の形態を採ることができる。   As mentioned above, although one Embodiment of the positioning method of the vehicle body part in the temporary hitting process was described, the positioning method and the positioning device 10 can take various forms without being limited to the above-described embodiment.

例えば、位置決め装置１０に関し、サイドメンバ６，６の位置決めを行うための第１当接部１８，１８と、ルーフパネル７の位置決めを行うための第２当接部１９，１９とを、それぞれ別体となるマニピュレータ１３（ないし駆動部１１）に取り付けた構成を採ることも可能である。また、第１当接部１８，１８が車幅方向に沿って互いに離反もしくは近接できる限りにおいてその移動機構は問わない。上記例示のように、レール部１５とスライド部１６との組合せに係る一方向移動機構に限らず、他の任意の移動機構（一方向もしくは他方向）を採用することもできる。適当なリンク機構等を介して左右の第１当接部１８，１８を同期して離反もしくは近接させることも可能である。第２当接部１９，１９に関しても、第１当接部１８，１８と同様に種々の移動機構を採用することが可能である。   For example, regarding the positioning device 10, the first contact portions 18 and 18 for positioning the side members 6 and 6 and the second contact portions 19 and 19 for positioning the roof panel 7 are separately provided. It is also possible to adopt a configuration attached to the manipulator 13 (or the drive unit 11) as a body. Further, as long as the first abutting portions 18 and 18 can be separated from or close to each other along the vehicle width direction, the moving mechanism is not limited. As illustrated above, not only the one-way moving mechanism related to the combination of the rail portion 15 and the slide portion 16 but also any other moving mechanism (one direction or another direction) may be employed. It is also possible to move the left and right first abutting portions 18 and 18 apart or close to each other in synchronization via an appropriate link mechanism or the like. As with the first contact portions 18 and 18, various moving mechanisms can be employed for the second contact portions 19 and 19.

また、第１当接部１８に関し、少なくともその一部が溝部８内に挿入可能でかつ挿入部分が内側面６ａと当接可能である限りにおいてその形状は任意である。例えば、第１当接部１８が、サイドメンバ６の内側面６ａと面接触する当接面形状を有するものであってもよい。第２当接部１９に関しても、第１当接部１８と同様に種々の形状を採ることが可能である。   Further, the shape of the first contact portion 18 is arbitrary as long as at least a part of the first contact portion 18 can be inserted into the groove portion 8 and the insertion portion can contact the inner side surface 6a. For example, the first contact portion 18 may have a contact surface shape that makes surface contact with the inner surface 6 a of the side member 6. As with the first contact portion 18, various shapes can be adopted for the second contact portion 19.

また、上記実施形態では、ワーク仮組ステーションＳ１上でフロアパネル５に対しサイドメンバ６，６およびルーフパネル７を一体に仮組みした後、搬送ライン下流に位置するワーク仮打ちステーションＳ２上でフロアパネル５とサイドメンバ６，６、および、サイドメンバ６，６とルーフパネル７とを仮打ちする場合を例示したが、もちろん、サイドメンバ６，６を一旦フロアパネル５に仮組して仮打ちにより固定した後、これらサイドメンバ６，６上にルーフパネル７を仮組して仮打ちにより固定する工程順を採ることも可能である。これに伴い、位置決め基準に関しても、図３に例示の形態に限ることなく、他の形態に係る位置決め基準を設定することも可能である。   In the above embodiment, after the side members 6 and 6 and the roof panel 7 are temporarily assembled integrally with the floor panel 5 on the workpiece temporary assembly station S1, the floor is formed on the workpiece temporary placement station S2 located downstream of the transfer line. Although the case where the panel 5 and the side members 6 and 6 and the side members 6 and 6 and the roof panel 7 are temporarily placed is illustrated, of course, the side members 6 and 6 are temporarily provisionally assembled to the floor panel 5 and temporarily placed. It is also possible to adopt a process sequence in which the roof panel 7 is temporarily assembled on the side members 6 and 6 and fixed by temporary striking after the fixing. Along with this, the positioning reference is not limited to the example illustrated in FIG. 3, and a positioning reference according to another form can be set.
