Description

この発明は、例えば、自動車製造ラインの塗装工程において、ドアを所定開度に固定するためのドア固定治具及びドア固定治具を用いたドアの開閉方法に関するのもであり、特に、コンベヤによる搬送時の振動等が原因でドアが開閉することを防止し、ドアを所定開度に確実に保持すると共に治具の小型化を図り、更には治具から剥離した塗料が車体に付着して塗装不良を生じることを防止することができるドア固定治具及びドア固定治具を用いたドアの開閉方法に係るものである。   The present invention relates to, for example, a door fixing jig for fixing a door at a predetermined opening in a painting process of an automobile production line, and a door opening / closing method using the door fixing jig. The door is prevented from opening and closing due to vibration during transportation, etc., the door is securely held at a predetermined opening, the jig is downsized, and the paint peeled off from the jig adheres to the vehicle body. The present invention relates to a door fixing jig and a door opening / closing method using the door fixing jig that can prevent the occurrence of poor coating.

自動車製造ラインの塗装工程では、ドアと車体表面との塗料の色調や光沢等を同一にするため、塗装時においてはドアを車体に対して所定の開度で固定した状態にしておき、この状態で下塗り、中塗り、上塗り等の各種塗装作業を行っている。
例えば、下塗り塗装工程においては、洗浄液が車体内に入りやすくするため車体に対するドアの開度を大きくした状態に固定し、また、中塗り・上塗り塗装工程においては、ドアと車体との色調・光沢等を同一にする為、ドアを車体に対して閉じた状態に固定して塗装作業が行われる。このようにドアを塗装工程で車体に固定するために、ドア固定治具が用いられる。
例えば、特許文献1には、基板にバネ部材による緩衝器を介して板状の磁石を固定したドア開閉補助装置を車体のサイドシル部に装着し、磁石をドアのインナパネルに吸着して保持し、ドアを閉鎖状態に保持すると共に、ドアへの過剰な押圧力を緩衝器で吸収する技術が開示されている。
In the painting process of the automobile production line, the paint color tone and luster of the door and the body surface are the same, so the door is fixed at a predetermined opening with respect to the body during painting. Various coating operations such as undercoating, intermediate coating, and topcoating are performed.
For example, in the undercoating process, the door opening with respect to the vehicle body is fixed to make the cleaning solution easily enter the vehicle body. In the intermediate coating and overcoating process, the color tone and gloss of the door and the vehicle body are fixed. In order to make the same, the painting work is performed with the door fixed to the closed state with respect to the vehicle body. Thus, in order to fix a door to a vehicle body in a painting process, a door fixing jig is used.
For example, in Patent Document 1, a door opening / closing auxiliary device in which a plate-like magnet is fixed to a substrate via a shock absorber by a spring member is attached to a side sill portion of a vehicle body, and the magnet is attracted and held on an inner panel of the door. A technique for holding a door in a closed state and absorbing excessive pressing force on the door with a shock absorber is disclosed.

実開昭61−006481号公報Japanese Utility Model Publication No. 61-006481

しかしながら、上記従来技術においては、ドアのインナパネルに凹凸部が多く形成されているため、磁石とインナパネルを強固に吸着させることは困難であり、例えば車体を搬送する際の振動等によってドアに開放力が作用した場合に、ドアと磁石が離間し易く搬送時にドアが開放される虞がある。また、ドアの保持力を向上するためには予め大型の磁石を用いる必要がある。
また、緩衝器により過剰な押圧力を吸収できるものの、ドアはドアレギュレータやウインドウガラス等のドア構成部品が収納される袋状部と、ウインドウガラスの昇降をガイドするドアサッシュ部とから構成され、ドアサッシュ部は袋状部に比べ剛性が低いために撓み易く、搬送時の振動等によって車体上側のドア開口フランジ部とドアが接触し、双方に外傷が生じる虞がある。
更に、ドアのインナパネルの塗装後に治具を用いた場合、磁石の吸着面の塗膜が剥離したり、剥離した塗料が車体に付着して塗装不良が生じたり、治具に付着した塗料が、剥離してドアステップ、サイドシルなどに付着して塗装不良を生じる虞がある。
そこで、この発明は、搬送時の振動によりドアが開閉するのを防止し、ドアを確実に保持すると共に小型化を図ることができるドア固定治具及びドア固定治具を用いたドアの開閉方法を提供するものである。
However, in the above prior art, since many uneven portions are formed on the inner panel of the door, it is difficult to firmly adsorb the magnet and the inner panel. When an opening force is applied, the door and the magnet are likely to be separated from each other, and the door may be opened during conveyance. Moreover, in order to improve the holding force of a door, it is necessary to use a large sized magnet beforehand.
In addition, although the excessive pressure can be absorbed by the shock absorber, the door is composed of a bag-like portion in which door components such as a door regulator and a window glass are stored, and a door sash portion that guides the window glass to be raised and lowered, Since the door sash part is less rigid than the bag-like part, the door sash part is easy to bend, and the door opening flange part on the upper side of the vehicle body and the door may come into contact with each other due to vibration during transportation, etc.
Furthermore, when a jig is used after painting the inner panel of the door, the paint film on the magnet's attracting surface peels off, the peeled paint adheres to the vehicle body, resulting in poor painting, or paint that adheres to the jig. There is a risk that it will peel off and adhere to the door step, side sill, etc., resulting in poor coating.
Therefore, the present invention prevents a door from opening and closing due to vibration during conveyance, and can securely hold the door and reduce the size, and a door opening and closing method using the door fixing jig Is to provide.

連結部材10は丸棒状の鋼材で形成され、基端側がフレーム12の折曲部12bの上面に固着され、先端部が車体内側に向けて緩やかにクランク状に曲がった状態で延設されている。この連結部材10の先端部に角板状の吸着プレート11が吸着面11bを車体内側、正確には車体側方に指向させ、上部の貫通孔11aが連結部材10によって貫通された状態で連結部材10に取り付けられている。この吸着プレート11の吸着面11bは平坦に形成され、後述する連結治具Cの磁石23及びホルダ25に対して十分に吸着状態を確保できるようになっている。   The connecting member 10 is formed of a round bar-like steel material, the base end side is fixed to the upper surface of the bent portion 12b of the frame 12, and the tip end portion extends in a state of being gently bent in a crank shape toward the inside of the vehicle body. . A square plate-like suction plate 11 is directed to the tip of the connection member 10 so that the suction surface 11b is directed to the inside of the vehicle body, more precisely to the vehicle body side, and the upper through hole 11a is penetrated by the connection member 10. 10 is attached. The suction surface 11b of the suction plate 11 is formed flat so that a suction state can be sufficiently secured with respect to a magnet 23 and a holder 25 of a connecting jig C described later.

図4、図5に示すように、このように構成されたドア側治具Bの位置決め部材15の屈曲部15aをスティフナSFの前縁部に車体前後方向で位置決めして係合させると共に、係合部材14をドアサッシュDSの溝部DS1に係合させて、車体上下方向を軸とした場合に回り方向の位置決めをし、かつ下部に設けた係止部材16の雌ねじ部16aに、スティフナSF、インナパネルD2を貫通して車体内側から固定ボルト31(先端にネジを有する)を締め付けて車体上下方向の位置決めをしている。
尚、図3、図5に鎖線で示すように、フレーム12の折曲部12bに上方に立ち上がるL字状の把持用のフック32を固定することで、ドア側治具Bの取り付け取り外し作業を行い易くすることもできる。
As shown in FIGS. 4 and 5, the bent portion 15a of the positioning member 15 of the door side jig B configured in this way is positioned and engaged with the front edge of the stiffener SF in the longitudinal direction of the vehicle body. When the joint member 14 is engaged with the groove portion DS1 of the door sash DS and the vertical direction of the vehicle body is used as an axis, the rotational direction is positioned, and the female screw portion 16a of the locking member 16 provided at the lower portion is provided with a stiffener SF, Positioning in the vertical direction of the vehicle body is performed by passing through the inner panel D2 and tightening a fixing bolt 31 (having a screw at the tip) from the inside of the vehicle body.
3 and 5, the L-shaped gripping hook 32 rising upward is fixed to the bent portion 12 b of the frame 12, so that the door side jig B can be attached and removed. It can also be done easily.

図6は連結治具Cの斜視図、図7は連結治具の下面図を示している。
図6、図7に示すように、連結治具Cは、車体側治具Aの係合部2に着脱自在に装着される連結治具本体17と、この連結治具本体17に連結部材18を介して取り付けられるマグネット部19とを備えている。
6 is a perspective view of the connecting jig C, and FIG. 7 is a bottom view of the connecting jig.
As shown in FIGS. 6 and 7, the connecting jig C includes a connecting jig main body 17 that is detachably attached to the engaging portion 2 of the vehicle body side jig A, and a connecting member 18 attached to the connecting jig main body 17. And a magnet part 19 attached via the.

連結治具本体17は、丸棒状の鋼材を下方に略直角に屈曲して形成され先細り状の第1脚部20aと、この第1脚部20aに一定距離を隔てて平行に配設された第2脚部20bを備えている。ここで、第1、第2の脚部20a,20b間の距離は車体側治具Aの円筒部材8a,8b間の距離と同一に設定されている。第1、第2の脚部20a,20bは、車体側治具Aの円筒部材8a,8bの内径よりも若干小径に形成されガタツキなく挿入する用になっており、第1、第2の脚部20a,20bの付け根部にはリング部材21a,21bが各々圧入されている。このリング部材21a,21bにより、第1、第2の脚部20a,20bを車体側治具Aの円筒部材8a,8bに挿入した際に連結治具Cの座りを良くしてガタツキを無くしている。   The connecting jig main body 17 is formed by bending a round bar-shaped steel material downward substantially at a right angle, and is tapered in parallel to the first leg portion 20a with a certain distance from the first leg portion 20a. A second leg 20b is provided. Here, the distance between the first and second leg portions 20a, 20b is set to be the same as the distance between the cylindrical members 8a, 8b of the vehicle body side jig A. The first and second leg portions 20a, 20b are formed to have a slightly smaller diameter than the inner diameter of the cylindrical members 8a, 8b of the vehicle body side jig A, and are inserted without rattling. Ring members 21a and 21b are press-fitted into the base portions of the portions 20a and 20b, respectively. The ring members 21a and 21b improve the sitting of the connecting jig C and eliminates rattling when the first and second leg portions 20a and 20b are inserted into the cylindrical members 8a and 8b of the vehicle body side jig A. Yes.

尚、第1、第2の脚部20a,20bが2個設けられた場合を例にして説明したが連結治具Cが車体側治具Aに対して回動規制されれば個数や形状は限定されない。また、例えば第1、第2の脚部20a,20b各々角柱に円筒部材8a,8bを四角柱形状に形成してもよく、このような四角柱形状を採用した場合には第1、第2の脚部20a,20bは一箇所でも回動が規制されるため、円筒形状部は一つ設けるだけで済む。   The case where two first and second leg portions 20a and 20b are provided has been described as an example. However, if the connection jig C is restricted from rotating with respect to the vehicle body side jig A, the number and shape are not limited. It is not limited. In addition, for example, the cylindrical members 8a and 8b may be formed in a quadrangular prism shape on each of the first and second leg portions 20a and 20b, and when such a quadrangular prism shape is adopted, the first and second Since the rotation of the leg portions 20a and 20b is restricted even at one location, it is only necessary to provide one cylindrical portion.

マグネット部19は、連結部材18にボルト24で固定されたロッドエンド22を備えている。ロッドエンド22は先端部に球面内輪22aを備えた周知の滑り軸受け部材である。球面内輪22aにはロッドエンド22の長手方向に直角にボルト26が挿通されている。ボルト26には頭部26a側から圧縮バネ29及びワッシャ28を順次挿通され、ボルト26の先端には球面内輪22aから突出する部分にスペーサ27を介して円筒状のホルダ25がねじ込み固定されている。そして、ホルダ25の内部に磁石23が嵌入されている。ここで、ホルダ25は有底円筒形状の部材であるが、このホルダ25の開口縁25bと磁石23の外面が着磁面として構成され、ドア側治具Bの吸着プレート11の吸着面11bに当接して吸着することになる。   The magnet unit 19 includes a rod end 22 fixed to the connecting member 18 with a bolt 24. The rod end 22 is a known sliding bearing member provided with a spherical inner ring 22a at the tip. Bolts 26 are inserted into the spherical inner ring 22 a at right angles to the longitudinal direction of the rod end 22. A compression spring 29 and a washer 28 are sequentially inserted into the bolt 26 from the head 26a side, and a cylindrical holder 25 is screwed and fixed to the tip of the bolt 26 through a spacer 27 at a portion protruding from the spherical inner ring 22a. . A magnet 23 is inserted into the holder 25. Here, the holder 25 is a bottomed cylindrical member, and the opening edge 25b of the holder 25 and the outer surface of the magnet 23 are configured as magnetized surfaces, and are formed on the suction surface 11b of the suction plate 11 of the door side jig B. It will come into contact and adsorb.

ホルダ25の底部25aにはボルト26と螺合されるネジ孔25cが形成され、スペーサ27はホルダ25の底部25aに締め付け固定されている。
したがって、ホルダ25は圧縮バネ29の弾性力により水平に保持されると共に、ホルダ25が傾動方向の力を受けた場合には、球面内輪22aが傾動するためホルダ25はロッドエンド22に対して首振り可能に支持されることとなる。
A screw hole 25c screwed with the bolt 26 is formed in the bottom 25a of the holder 25, and the spacer 27 is fastened and fixed to the bottom 25a of the holder 25.
Therefore, the holder 25 is held horizontally by the elastic force of the compression spring 29, and when the holder 25 receives a force in the tilting direction, the spherical inner ring 22a tilts, so the holder 25 is necked with respect to the rod end 22. It will be supported in a swingable manner.

次に、作用について説明する。
先ず、ドアDを開いた状態で、図2に示すように、車体側治具Aのフレーム3のフック部3aを、センターピラーSに形成された部品取付孔S1に係合すると共に挟持部材5の溝部5aをセンターピラーSの前側縁S2に係合させ、車体のセンターピラーSに車体側治具Aを位置決めして装着する。
Next, the operation will be described.
First, with the door D opened, as shown in FIG. 2, the hook portion 3a of the frame 3 of the vehicle body side jig A is engaged with the component mounting hole S1 formed in the center pillar S and the clamping member 5 is engaged. The groove portion 5a is engaged with the front side edge S2 of the center pillar S, and the vehicle body side jig A is positioned and mounted on the center pillar S of the vehicle body.

また、図4、図5に示すように、ドア側治具Bの位置決め部材15を、インナパネルD2に接合されたスティフナSFの前縁部に係合させると共に係合部材14をドアサッシュDSの溝部DS1に係合させ、かつ下部に設けた係止部材16の雌ねじ部16aにスティフナSF、インナパネルD2を貫通して車体内側から固定ボルト31を締め付けて位置決め固定する。   4 and 5, the positioning member 15 of the door side jig B is engaged with the front edge portion of the stiffener SF joined to the inner panel D2, and the engaging member 14 of the door sash DS is engaged. The stiffener SF and the inner panel D2 are passed through the female threaded portion 16a of the locking member 16 provided at the lower portion and engaged with the groove portion DS1, and the fixing bolt 31 is tightened and fixed from the inside of the vehicle body.

次に、図8に示すように、車体側治具Aの円筒部材8a,8bに連結治具Cの第1、第2脚部20a,20bを挿入し、車体側治具Aに連結治具Cを装着する。
この時、連結治具Cの磁石23の先端部は、車体のドア取り付け開口部の下辺を構成する車体部材であるドアステップ(図示せず)より車内側に位置している。
そして、車体側治具A、ドア側治具B、連結治具Cが装着された状態でドアDを閉じると、ドア側治具Bの吸着プレート11の吸着面11bに、連結治具Cの磁石23及びホルダ25の開口縁25bが着磁面として吸着して連結治具Cが車体側治具Aとドア側治具Bとを連結して車体に対してドアDが固定される。
Next, as shown in FIG. 8, the first and second leg portions 20a and 20b of the connecting jig C are inserted into the cylindrical members 8a and 8b of the car body side jig A, and the connecting jig is inserted into the car body side jig A. Wear C.
At this time, the tip of the magnet 23 of the connecting jig C is located on the vehicle interior side from a door step (not shown) which is a vehicle body member constituting the lower side of the door attachment opening of the vehicle body.
Then, when the door D is closed with the vehicle body side jig A, the door side jig B, and the connection jig C mounted, the connection jig C is placed on the suction surface 11b of the suction plate 11 of the door side jig B. The opening edge 25b of the magnet 23 and the holder 25 is attracted as a magnetized surface, the connecting jig C connects the vehicle body side jig A and the door side jig B, and the door D is fixed to the vehicle body.

また、搬送時の振動等でドアDが開放側に力を受けたとしても、ボルト26がロッドエンド22の球面内輪22aの中心軸線回りに揺動可能となっており、磁石23を保持するホルダ25が首振り可能となっているため、磁石23及びホルダ25の開口縁25bは吸着プレート11に面接触していて磁力が均一になり、また圧縮バネ29の弾性力によってドアDを開放しようとする力が減衰され、振動に伴う衝撃力も吸収されるため、磁石23及びホルダ25と吸着プレート11が離間し難くなる。
尚、ドアDを開放する場合は、磁石23及びホルダ25と、吸着プレート11との着磁力以上の力でドアを引っ張ればよい。
Further, even if the door D receives a force on the open side due to vibration during transportation, the bolt 26 can swing around the central axis of the spherical inner ring 22a of the rod end 22 and holds the magnet 23 25 is swingable, the opening edge 25b of the magnet 23 and the holder 25 is in surface contact with the suction plate 11 so that the magnetic force is uniform, and the door D is opened by the elastic force of the compression spring 29. Since the force to be attenuated and the impact force due to vibration are absorbed, the magnet 23 and the holder 25 are not easily separated from the suction plate 11.
In addition, what is necessary is just to pull a door with the force more than the magnetizing force of the magnet 23 and the holder 25, and the adsorption | suction plate 11, when opening the door D. FIG.

ここで、ドアDを所定の位置で閉止した際に、連結治具Cの磁石23がドア側治具Bの吸着プレート11と吸着するように、予めドア側治具Bの連結部材10の長さが調整されているため、連結部材10の長さを変更するだけでドアDの開度を容易に変更することができる。
また、図3、図5に鎖線で示すように、ドア側治具Bのフレーム12の折曲部12bの上面にフック32を形取り付けることで、図示しないドア開閉装置または作業者によるドアDの開放操作を容易に行うことができる。
Here, when the door D is closed at a predetermined position, the length of the connecting member 10 of the door-side jig B is previously set so that the magnet 23 of the connecting jig C is attracted to the suction plate 11 of the door-side jig B. Therefore, the opening degree of the door D can be easily changed simply by changing the length of the connecting member 10.
3 and 5, a hook 32 is attached to the upper surface of the bent portion 12b of the frame 12 of the door side jig B, so that the door opening / closing device (not shown) or the door D by the operator The opening operation can be easily performed.

尚、図9はロック部材の斜視図である。自動車製造ラインの中塗り・上塗り塗装工程においては前述したように、車体側治具Aとドア側治具Bとを連結治具Cで連結してドアDを閉鎖した状態にしたが、その前工程である下塗り工程においては、図10に示すように、連結治具Cを取り付けずロック部材33を用いてドアDを車体に対して開度を大きくした状態で固定する。   FIG. 9 is a perspective view of the lock member. In the intermediate coating and top coating process of the automobile production line, as described above, the vehicle body side jig A and the door side jig B are connected by the connecting jig C so that the door D is closed. In the undercoating process, which is a process, as shown in FIG. 10, the door D is fixed with respect to the vehicle body with the opening degree increased using the lock member 33 without attaching the connecting jig C.

具体的には、ロック部材33は連結治具Cと同様の構成の第1、第2脚部33a,33bを備え、この第1、第2脚部33a,33bから車体外側に延びるアーム部34の端部に下側に延びる係止端35を備えている。アーム部34は車体内部に下塗り工程における電着液が流れ込むのに十分な開口が確保される長さに設定されている。ここで、第2脚部33bの基部にはリング部材34bが設けられている。このように構成されたロック部材33を連結治具Cと交換するだけで、ドアDの保持姿勢の変化、つまりドアDを開放した状態で保持する場合に対応できる。   Specifically, the lock member 33 includes first and second leg portions 33a and 33b having the same configuration as that of the connecting jig C, and an arm portion 34 extending outward from the first and second leg portions 33a and 33b. A locking end 35 that extends downward is provided at the end of each. The arm portion 34 is set to a length that ensures a sufficient opening for the electrodeposition liquid in the undercoating process to flow into the vehicle body. Here, a ring member 34b is provided at the base of the second leg portion 33b. By simply replacing the lock member 33 configured in this manner with the connecting jig C, it is possible to cope with a change in the holding posture of the door D, that is, when the door D is held open.

図11〜図13は、上述したドア固定治具を用いてドアDを固定した状態で車体を搬送する状況を示した図である。
図11に示すように、レール100上をガイドGを介して(図11中左側に)走行する台車本体101には、後端部を走行方向の上流側に向けた車体を載置する揺動プレート102が下流側の軸Jを中心にして傾動可能に配設され、揺動プレート102の後部には揺動プレート102の幅方向外側に一対のローラ103,103が配設されている。
FIGS. 11-13 is the figure which showed the condition which conveys a vehicle body in the state which fixed the door D using the door fixing jig mentioned above.
As shown in FIG. 11, the cart body 101 that travels on the rail 100 via the guide G (on the left side in FIG. 11) swings to place the vehicle body with the rear end facing upstream in the traveling direction. The plate 102 is disposed so as to be tiltable about the downstream axis J, and a pair of rollers 103 are disposed on the rear side of the swing plate 102 in the width direction of the swing plate 102.

図12に示すように、ドアDを開放する工程ではレール100,100の外側にローラ103に係合するガイドレール104,104が併設されている。このガイドレール104,104は両端部が斜め下側に傾斜して中央部に高床の水平部が形成されており、ローラ103,103がガイドレール104,104の走行方向上流側の端部に乗り上がり水平部に至ると揺動プレート102が軸Jを中心に走行方向に対して前傾し、車体が、車体の前端方向に対して前傾姿勢となる。   As shown in FIG. 12, in the step of opening the door D, guide rails 104 and 104 that engage with the roller 103 are provided outside the rails 100 and 100. Both ends of the guide rails 104 and 104 are inclined obliquely downward, and a horizontal portion of an elevated floor is formed in the center. The rollers 103 and 103 ride on the end of the guide rails 104 and 104 on the upstream side in the traveling direction. When the ascending horizontal portion is reached, the rocking plate 102 tilts forward with respect to the traveling direction about the axis J, and the vehicle body leans forward with respect to the front end direction of the vehicle body.

ここで、通常(ドア閉時)は揺動プレート102は走行方向の上流側が下側に下がる後傾状態となっていて(図11参照)、車体は前端方向に対して後傾した状態、すなわちドアDを支持する側(ヒンジ側)を、支持しない側よりも高い状態に傾斜させることで、ドアDに閉まり方向の力が作用しドアDの閉鎖状態が維持され、搬送時の振動等でドアDが開放することが防止される。
また、ドア開放時には、ローラ103,103がガイドレール104,104に乗り上がることにより揺動プレート102が走行方向の下流側に前傾されて、車体は前端方向に対して前傾した状態、すなわちドアDを支持する側(ヒンジ側)を、支持しない側よりも低い状態に傾斜させることで、ドアDに開放方向の力が作用し、開放後は自重により開放状態が維持される。
Here, normally (when the door is closed), the swing plate 102 is in a rearward tilted state where the upstream side in the traveling direction is lowered downward (see FIG. 11), and the vehicle body is tilted rearward with respect to the front end direction, that is, By tilting the side supporting the door D (the hinge side) to a higher state than the side not supporting the door D, a force in the closing direction acts on the door D to maintain the closed state of the door D. The door D is prevented from opening.
In addition, when the door is opened, the rollers 103 and 103 run on the guide rails 104 and 104 so that the swing plate 102 is tilted forward in the traveling direction, and the vehicle body is tilted forward with respect to the front end direction. By tilting the side that supports the door D (the hinge side) to a lower state than the side that does not support the door D, a force in the opening direction acts on the door D, and the opened state is maintained by its own weight after opening.

このような搬送コンベヤを用いることにより、通常ドアDを閉じて搬送する時は、揺動プレート102を車体前端方向に対して後傾させて車体を後傾姿勢に支持して搬送することで前ヒンジのドアDに閉じ方向の力が作用して閉鎖状態を維持することができると共に、ドア固定治具による磁力、つまりドア側治具Bの吸着プレート11と、連結治具Cの磁石23の着磁力でドアDを確実に固定することができる。   By using such a transport conveyor, when the door D is normally closed and transported, the swing plate 102 is tilted rearward with respect to the front end direction of the vehicle body, and the vehicle body is supported in a rearward tilted state and transported. The closing force can be applied to the hinge door D to maintain the closed state, and the magnetic force generated by the door fixing jig, that is, the suction plate 11 of the door side jig B and the magnet 23 of the connecting jig C can be maintained. The door D can be reliably fixed by the magnetic force.

また、ドアDの開放時にはローラ103,103がガイドレール104,104に乗り上がると、揺動プレート102を車体前端方向に対して前傾させ、車体を前傾姿勢に支持することでドアDに開放力が作用するため、ドア固定治具の磁石23と吸着プレート11との吸着状態を容易に解除でき、開放後はドアDの自重でドアDが開放される。
したがって、前述した中塗り・上塗り塗装工程の際には磁石23と吸着プレート11とで強固にドアDを車体に固定することができるため、次の工程においてドアDを開く必要がある際には、作業者のドアDの開放操作にはその分だけ余分な力が必要となるが、このように台車本体101の揺動プレート102をガイドレール104によって傾動状態を変更することで、ドアDの自重を利用し作業者にかかる負担を軽減することができる。
When the door 103 is opened, when the rollers 103 and 103 ride on the guide rails 104 and 104, the swing plate 102 is tilted forward with respect to the front end direction of the vehicle body, and the vehicle body is supported in a forward tilted posture. Since the opening force acts, the suction state between the magnet 23 of the door fixing jig and the suction plate 11 can be easily released, and the door D is opened by its own weight after opening.
Accordingly, the door D can be firmly fixed to the vehicle body by the magnet 23 and the suction plate 11 during the above-described intermediate coating / top coating process, so when the door D needs to be opened in the next process. An extra force is required for the operator's opening operation of the door D. By changing the tilting state of the swing plate 102 of the carriage body 101 by the guide rail 104 in this manner, It is possible to reduce the burden on the worker by using the own weight.

上記実施形態によれば、車体側治具Aに取り付けられる連結治具Cのボルト26がロッドエンド22の球面内輪22aの軸線回りに揺動することで、ホルダ25を車体側方を軸として首振り可能とすることができるため、ホルダ25及び磁石23はドア側治具Bの吸着プレート11の吸着面11bに面接触して磁力が均一になり、ドアDが開き方向に変位してもホルダ25及び磁石23と吸着プレート11が離間され難くなる。よって、ドアDを確実に固定することができる。   According to the above embodiment, the bolt 26 of the connecting jig C attached to the vehicle body side jig A swings around the axis of the spherical inner ring 22a of the rod end 22 so that the holder 25 is necked about the vehicle body side. Since the holder 25 and the magnet 23 can come into contact with the suction surface 11b of the suction plate 11 of the door side jig B, the magnetic force becomes uniform, and the holder D is displaced even when the door D is displaced in the opening direction. 25 and the magnet 23 and the adsorption | suction plate 11 become difficult to space apart. Therefore, the door D can be reliably fixed.

また、圧縮バネ29の弾性力によって、ドアDが開放しようとする方向へ力を受けた場合にこの力を減衰させることができると共に、搬送時などの衝撃力が吸収されるため、この点でもホルダ25及び磁石23と吸着プレート11が離間され難くなり、ドアDを確実に固定することができる。また、確実にホルダ25及び磁石23と吸着プレート11との吸着力を確保できるため磁石23を小型化できる。   Further, when the force is applied in the direction in which the door D is to be opened due to the elastic force of the compression spring 29, this force can be attenuated and the impact force during transportation is absorbed. It becomes difficult for the holder 25 and the magnet 23 and the attraction plate 11 to be separated from each other, and the door D can be reliably fixed. Further, since the attracting force between the holder 25 and the magnet 23 and the attracting plate 11 can be ensured, the magnet 23 can be downsized.

更に、連結治具Cの磁石23とドア側治具Bの吸着プレート11が、ドアステップよりも車内側で吸着される構成としたので、吸着プレート11等から剥離した塗料が、ドアステップ上に落下し塗装不良が生じるのを防止できる。
また、車体骨格部材であるセンターピラーS近傍でドアDを強固に固定するため、ドアDが撓んでドアDが車体のドア取り付け開口部の周縁フランジ等に接触することがなくなり、車体及びドアDの傷付きを防止できる。
Further, since the magnet 23 of the connecting jig C and the suction plate 11 of the door side jig B are sucked inside the vehicle from the door step, the paint peeled off from the suction plate 11 and the like is placed on the door step. It can prevent falling and poor painting.
Further, since the door D is firmly fixed in the vicinity of the center pillar S, which is a vehicle body skeleton member, the door D is not bent and does not come into contact with the peripheral flange or the like of the door mounting opening of the vehicle body. Can prevent scratches.

尚、この発明は上記実施形態に限られるものではなく、例えば、図14に示すように、連結治具Cはロッドエンド22を用いた構造に限られるものではない。例えば、ロッドエンド22を用いることなく、ボルト26を大径の孔30aを有する基板30に挿通し、この基板30に前述した実施形態と同様に圧縮バネ29、ワッシャ28、スペーサ27’を組み付けて、ホルダ25を水平にした状態でホルダ25を孔30aの範囲で孔30aを中心軸線回りに揺動可能としても良い。また、ボルト26を棒材とし、この棒材の先端にホルダ25を固着しても良い。
そして、圧縮ばね29やロッドエンド22に塗料が付着することを防止するため、例えば連結部材18の部分から圧縮ばね29やロッドエンド22の部分に渡ってカバー部材を被せるようにしてもよい。
更に、ドア側治具Bに吸着プレート11を、連結治具Cにマグネット部19を設けたが、ドア側治具Bにマグネット部19を、連結治具Cに吸着プレート11を設ける構成としてもよい。
また、対象となるドアDは右側のフロントサイドドアに限られず、左側のフロントサイドドアや、左右のリヤサイドドアにも適用できる。そして、ドア取り付け開口部の下辺を構成する車体部材としてはドアステップ以外にサイドシルも含まれる。
そして、磁石23とホルダ25の開口縁25bが吸着プレート11の吸着面11bに吸着する場合について説明したが、磁石23をホルダの内部に収め、ホルダ25の開口縁25bを吸着プレート11の吸着面11bに吸着させるようにしてもよい。この場合には、ホルダ25の首振り構造により、確実に吸着面11bに対してホルダ25の開口縁25bを一致させることができる効果がある。
In addition, this invention is not restricted to the said embodiment, For example, as shown in FIG. 14, the connection jig | tool C is not restricted to the structure using the rod end 22. As shown in FIG.
