Description

【0001】
【発明の属する技術分野】
本発明は、板金で形成された前側板、後側板、これら両側板に懸架される懸架部材、及び当該両側板の下部に接合されて両側板を支持するベース部材とからなる筐体を組み立てるための治具に関する。
【0002】
【従来の技術】
画像形成装置の枠組となる筐体として、角型の中空形状のパイプ(以下、角パイプという)を組み立てた筐体が使用されているが、製造コストを低減するために、板金をプレス加工で打ち抜いたものを前後面の側板として組み立てた筐体が提案されている。この板金製の筐体の組み立ては、ベース部材に対して前後面の側板を直交させた状態で位置決めして、前後面の側板の下部をベース部材に接合し、更に、ベース部材に接合した両側板の間に懸架部材を接合することによって行われている。
【0003】
【発明が解決しようとする課題】
しかしながら、上述のようにして板金製の筐体を組み立てる場合、ベース部材に対して前後側板を位置決めする作業、前後側板をベース部材に直交した姿勢で保持する作業、及び懸架部材を前後側板に位置決めする作業に手間を要する。また、ベース部材に対する前後側板の姿勢が不正確であったり、前後側板のベース部材に対する位置決め及び懸架部材の前後側板に対する位置決めが不正確であると、各部材の接合部分の強度が不十分になる。このことは、筐体の基体となる前後面の側板に撓み(ひずみ)が発生しやすく、筐体内に備え付けた内部機器の位置精度がひずみ等の影響で保てなくなるという問題の要因となる。
【0004】
本発明は、このような問題点を解決するためになされたものであり、板金製の筐体を組み立てるにあたり、前後側板のベース部材への位置決め、及びベース部材に対する前後側板の姿勢の保持を正確かつ簡単に行うことができる治具を提供することを目的とする。
【0005】
【課題を解決するための手段】
上記目的を達成するために請求項1に記載の発明は、板金で形成された前側板、後側板、これら両側板に懸架される懸架部材、及び当該両側板の下部に接合されて両側板を支持するベース部材とを有する筐体を組み立てるための治具であって、
前記ベース部材を保持するベース保持部と、
各側板用に前記ベース保持部上に並列して配置され、前記側板を前記ベース部材に略直交する姿勢で保持すると共に、前記懸架部材を前記前後側板の間に懸架された状態で保持する側板保持部とを有し、
少なくともいずれかの側板用の側板保持部は、前記ベース保持部上でスライド移動自在に設けられており、
前記ベース保持部及び側板保持部は、前記前後側板、懸架部材及びベース部材の接合ポイントを避けた位置において、前記前後側板、懸架部材及びベース部材を保持するものである。
【0006】
この構成によれば、ベース保持部に保持されたベース部材に対して、側板保持部によって前後側板が略直交した姿勢で保持されるため、ベース部材に対する前後側板の姿勢保持を簡単かつ正確に行うことができる。また、側板保持部がベース保持部に対してスライド移動自在とされているので、ベース部材に対する前後側板の位置決めを簡単に行うことができる。これにより、各部材を精度良く接合することができ、各部材の接合部分の強度の向上を図ることができる。
【0007】
また、請求項2に記載の発明は、請求項1に記載の筐体組み立て治具であって、前記並列して配置された各側板保持部の間に長尺状部材が挟み込まれ、側板保持部の上端部近傍に固定された状態で、前記接合作業が可能に構成されているものである。
【0008】
この構成によれば、上記長尺状部材によって、ベース保持部上に並列して配置されている両側板保持部の上端部近傍同士が固定され、当該上端部間の距離が一定に保たれるので、ベース保持部上における側板保持部のぶれが軽減され、側板保持部の姿勢が安定する。これにより、側板保持部のベース保持部への設置面積を大きくしなくても、ベース保持部上における側板保持部の姿勢を安定させることができ、治具のダウンサイジング化を図ることができる。
【0009】
また、請求項3に記載の発明は、請求項1又は請求項2に記載の筐体組み立て治具であって、前記側板保持部には、前記側板に対向する面に突出部が設けられており、前記側板に形成された孔部が当該突出部に嵌合されることによって、前記側板保持部に前記側板が位置決めされるものである。
【0010】
この構成によれば、側板保持部の突出部に側板の孔部を嵌合させることによって、簡単かつ正確に、側板保持部に対する側板の位置決めを行うことができる。
【0011】
また、請求項4に記載の発明は、請求項1乃至請求項3のいずれかに記載の筐体組み立て治具であって、前記側板保持部には、前記懸架部材に対向する面に突出部が設けられており、当該突出部に、前記側板及び懸架部材に形成された孔部が嵌合されることによって、前記側板に前記懸架部材が位置決めされるものである。
【0012】
この構成によれば、側板保持部の突出部に側板及び懸架部材の孔部を嵌合させることによって、簡単かつ正確に、側板に対する懸架部材の位置決めを行うことができる。
【0013】
【発明の実施の形態】
以下、本発明の一実施形態に係る筐体組み立て治具について図面を参照して説明する。図1は本発明に係る筐体組み立て治具を示す斜視図、図2は当該治具によって組み立てられる筐体を示す斜視図、図3は当該治具の正面図、図4は当該治具の右側面図、図5は当該治具の平面図である。
【0014】
本発明の筐体組み立て治具(以下、治具という)1は、コピー機,プリンタ等の画像形成装置の枠組となる筐体2を組み立てるためのものであり、筐体2は主に板金からなる部材が接合されてなるものである。
【0015】
筐体2は、その土台となるベース部材22と、ベース部材22に垂直な状態で接合され、下部がベース部材22に支持されている前側板23と、前側板23に並列させた状態で、ベース部材22に垂直な状態で取り付けられ、下部がベース部材22に支持されている後側板24とを有し、更に、前側板23及び後側板24の上部に、両側板23,24の間に懸架させるようにして接合された上板部材25と、前側板23及び後側板24の上部及び略中央部に、前側板23及び後側板24の間に懸架されるようにして接合されたステイ(懸架部材)261,262,263とからなる。前側板3及び後側板4は板金からなり、その上部、下部及び側部は約90度の角度で前方向に折り曲げられて接合代231,232,233,234,241,244等が形成されている。これら前側板23、後側板24、ベース部材22及びステイ261,262,263は、図2に溶接ポイントPで示す位置等において溶接される。
【0016】
治具1は、主に、ベース部材22を保持するベース保持部12と、前側板23をベース部材22に略直交する姿勢で保持する側板保持部13と、後側板24をベース部材22に略直交する姿勢で保持する側板保持部14とからなる。側板保持部13,14は互いに並列して配置された状態でベース保持部12上に配置されており、上記ステイ263を前側板23及び後側板24の間に懸架された状態で保持することが可能とされている。また、側板保持部13はベース保持部12上でスライド移動自在に設けられている。
【0017】
ベース保持部12及び側板保持部13,14は、ベース部材22、前側板23及び後側板24を位置決めした状態で、前側板23、後側板24及びステイ261,262,263に対する接合作業が可能となるように、接合作業に差し支えのない位置において、ベース部材22、前側板23、後側板24及びステイ261,262,263を保持するようになっている。
【0018】
ベース保持部12は、その上に載置されたベース部材22を略水平な姿勢で保持するものであり、ベース部材22の下面に当接し、ベース部材22を支える複数のベース部材載置部121が設けられている。
【0019】
側板保持部13は、前側板23に当接して前側板23の姿勢を支持する2つの側板支持部材131と、前側板23を側板支持部材131に固定する複数のホールド部132と、側板支持部材131の下部に接合され、水平方向にスライド移動自在に、ベース保持部12のレール123に取り付けられたスライド部133とを有している。側板支持部材131は、スライド部133(ベース保持部12)に対して略直交する姿勢で取り付けられており、側板支持部材131とスライド部133との接合部分には、側板支持部材131の姿勢の保持・接合部の補強のために、三角形状の補強板134が取り付けられている。
【0020】
前記ホールド部132として、側板支持部材131にあてがわれた前側板23の側板本体部230を側板支持部材131に押さえ付ける第1ホールド部132aと、前側板23の接合代232,234を側板支持部材131に押さえ付ける第2ホールド部132bとが複数備えられている。これらは、いずれも前側板23をベース部材22に接合する際の溶接や、ステイ261,262,263を前側板23に取り付ける際の溶接作業に支障を生じない位置に配置されている。
【0021】
なお、第1ホールド部132a及び第2ホールド部132bとしてはトグルクランプ等が使用され、レバー部分を回転させると、側板を押圧する先端部分が、側板に対して接離方向に移動するようになっている。このレバー部分を回転させることで、側板の支持部材への固定又はその解除が自在となっている。第1ホールド部132a及び第2ホールド部132bの先端部分は、側板溶接時の押圧力,作業性,耐久性を考慮して、金属で形成されることが好ましい。
【0022】
一方、後側板24を保持する側板保持部14は、ベース保持部12上に固定されている。側板保持部14も、側板保持部13と同様の構成でなる側板支持部材141及び補強板144、第1ホールド部142a及び第2ホールド部142bからなるホールド部142を有している。また、各側板保持部13,14の側板支持部材131,141には、撓みや歪みを防止するために補強部材131a,141aが各側板支持部材131,141の間に懸架されるようにして接合されている。
【0023】
また、両側板保持部13,14の上端部近傍には、ロッド(長尺状部材)16が側板保持部13,14の間に挟み込まれて固定されるようになっている。これは、一方の側板支持部材131,141の間には、その上端部近傍に設けられた輪状のロッド取付部135,145にロッド16が嵌め込まれることによって固定される。他方側の側板支持部材131,141の間へのロッド16の固定は、例えば、側板支持部材131,141の外側面から(側板支持部材131,141を貫通させて)、中空形状等とされたロッド16の中空部分にピンを嵌入することによって行われる。これにより、前側板23が保持される側板保持部13と、後側板24が保持される後側板保持部14との上部が固定され、当該上端部間の距離が一定に固定されるので、ベース保持部12上での側板保持部13,14のぶれが軽減され、側板保持部13,14の姿勢が安定する。これにより、補強板134,144の下部面積を大きくする等によって、側板保持部13,14のベース保持部12への設置面積を大きくしなくても、ベース保持部12上における側板保持部13の姿勢を安定させることができる。
【0024】
次に、側板保持部13,14への前側板23及び後側板24の位置決め及び取り付けについて説明する。図6は側板保持部13への前側板23の取り付けを示す斜視図、図7は治具1に筐体2の各部材が位置決め及び保持されている状態を示す斜視図、図8は前側板23及び後側板24とステイ263との接合部分を示す図である。各側板保持部13の側板支持部材131には、側板を側板支持部材131に位置決めするための位置決めピン(突出部)131bが設けられている。この位置決めピン131bは、本実施形態では、側板支持部材131上部の両側端部、及び下部の一側端部に設けられている。これら3点の位置決めピン131bに、前側板23に設けられた孔部23bが嵌合されることによって、側板支持部材131に対して前側板22が位置決めされる。後側板24にも同様に位置決めピンが設けられており、側板支持部材141に対する後側板24の位置決めも同様にして行われる。このようにして、前側板23及び後側板24を側板保持部13,14に位置決めした後、側板保持部13,14の第1ホールド部132a,142a及び第2ホールド部132b,142bによって、前側板23及び後側板24を側板支持部材131,141に固定する。
【0025】
なお、本実施形態では、位置決めピン131bは、側板保持部13に3つ設けられた形態を示しているが、側板保持部13,14に、これとは異なる数の位置決めピンが設けられた構成としてもよい。
【0026】
次に、前側板23及び後側板24に対するステイ261,262,263の位置決め及び保持について説明する。図8に示すように、側板保持部13,14の側板支持部材131の側部、すなわち、前側板23の接合代234及び後側板24の接合代244に対向する部分には、ステイ263を当該接合代234,244に対して位置決めするための突出部131cが設けられている。前側板23及び後側板24は、位置決めピンを利用して側板支持部材131,141に位置決めされると共に、前側板23及び後側板24の接合代234,244に形成されている孔部に突出部131cが嵌合されるようになっている。突出部131cは、前側板23及び後側板24の接合代234,244の孔部を貫通して突出するようになっており、この突出部131cにステイ263の孔部を嵌合させて、前側板23及び後側板24の接合代234,244に対してステイ263を位置決めする。ステイ263の孔部を突出部131cに嵌合させた後、ホールド部132b及び142bによってステイ263を前側板23及び後側板24に固定する。
【0027】
また、治具1は、図7及び図8に示すように、上記ベース保持部12、側板保持部13,14、側板支持部材131,141、ホールド部142は、前側板23、後側板24、ステイ261,262,263及びベース部材22を保持した状態で、前側板23、後側板24、ステイ261,262,263及びベース部材22に対する接合作業が可能となるように、各部材の溶接ポイントPを避けた場所で各部材を支持及び固定している。
【0028】
治具1を用いた筐体2の組み立て方法について説明する。図7は治具1に筐体2の各部材が保持・位置決めされた状態を示す斜視図である。まず、ベース保持部12のベース部材載置部121にベース部材22を載置する。そして、側板保持部14の側板支持部材141の位置決め用突出部に、後側板24の孔部を嵌合させて、側板支持部材141に後側板24を位置決めする。このとき、後側板24の側部の接合代244等に形成された孔部を、側板支持部材141側部の突出部141cに嵌合させる。この後、ホールド部142aで後側板24を側板支持部材141に固定する。
【0029】
次に、側板保持部13をベース保持部12上でスライド移動させ、ベース部材12に前側板23を取り付けようとする位置で停止させる。この位置において、側板保持部13の側板支持部材131の突出部131bに、前側板23の孔部23bを嵌合させて、側板支持部材131に対して前側板23を位置決めする。このとき、前側板23の接合代234等の孔部を、側板支持部材131の側部の突出部131cに嵌合させる。この後、ホールド部132によって前側板23を側板支持部材131に固定する。
【0030】
そして、ロッド16を側板保持部13及び側板保持部14の間に懸架させて、側板保持部13,14の上部に固定する。次に、側板保持部13,14に保持された前後側板23,24の接合代234,244の穴部から突出している突出部131c,141cに対して、ステイ263の孔部を嵌合させ、前後側板23,24に対するステイ263を位置決めする。この後、第2ホールド部131b及び142bによって、ステイ263を前側板23及び後側板24に固定する。
【0031】
更に、この状態において前側板23及び後側板24の上端部の両側に、ステイ261,262を両側板間に懸架させるようにしてあてがい、第2ホールド部132b及び142bによって前後側板23,24に固定する。なお、ステイ261,262についても、側板支持部材131及び141に突出部を設けておき、この突出部に前側板23及び後側板24の孔部及びステイ262,263の孔部を嵌合させることによって、前側板23及び後側板24に対する位置決めを行うようにしてもよい。
【0032】
このように、治具1によって筐体2の各部材が位置決めされた状態において、前側板23、後側板24、ベース部材22及びステイ261,262,263の溶接作業を行って各部材を接合する。接合後は、側板保持部13,14のホールド部132,142を解除し、側板保持部13をスライド移動させて筐体2から離間させて、治具1から筐体2を取り外すようにする。
【0033】
このように、本実施形態の治具1によれば、ベース部材22に対する前側板23及び後側板24の姿勢保持及び位置決めを簡単かつ正確に行うことができる。これにより、筐体2を構成する各部材を高精度で接合することができ、各部材の接合部分の強度の向上を図ることができる。
【0034】
なお、本発明は上記実施の形態の構成に限られず種々の変形が可能である。例えば、上記実施の形態では、側板保持部13,14に対する位置決めを、側板支持部材131,141の突出部に対して、前後側板23,24の孔部23b,24bを嵌合させて行っているが、かかる突出部を設けずに、側板支持部材131,141に前後側板23,24をあてがってホールド部132,142で固定することのみによって位置決めを行うようにしてもよい。同様に、前後側板23,24に対するステイ263の位置決めについても、突出部を設けずにホールド部132,142のみによって行うようにしてもよい。
【0035】
また、上記実施形態では、溶接作業時には、側板保持部13,14の上端部同士をロッド16によって固定するようにしているが、側板支持部材131,141に取り付けられた補強板134,144の下部面積を大きくすることによって、側板支持部材131,141の姿勢を安定させ、ぶれを防止するようにしてもよい。
【0036】
さらに、上記実施形態では、前側板23を保持する側板保持部13がベース保持部12上でスライド移動するように構成されているが、後側板24を保持する側板保持部14のみ、又は側板保持部13,14の両方がスライド移動可能となるように構成してもよい。
【0037】
【発明の効果】
以上のように本発明によれば、ベース保持部に保持されたベース部材に対して、側板保持部によって前後側板が略直交した姿勢で保持されるため、ベース部材に対する前後側板の姿勢保持を簡単かつ正確に行うことができる。また、側板保持部がベース保持部に対してスライド移動自在とされているので、ベース部材に対する前後側板の位置決めを簡単に行うことができる。これにより、各部材を高精度で接合することができ、各部材の接合部分の強度の向上を図ることができる。
【0038】
また、長尺状部材によって両側板保持部の上端部同士を固定するようにすれば、当該上端部間の距離が一定に保たれるので、ベース保持部上における側板保持部のぶれが軽減され、側板保持部の姿勢が安定する。これにより、側板保持部のベース保持部への設置面積を大きくしなくても、ベース保持部上における側板保持部の姿勢を安定させることができ、治具のダウンサイジング化を図ることができる。
【0039】
また、側板保持部の側板に対向する面に突出部を設け、側板の孔部に嵌合させることによって、側板保持部に対して側板を位置決めするようにすれば、側板保持部に対する側板の位置決めを簡単かつ正確に行うことができる。
【0040】
また、側板保持部の懸架部材に対向する面に突出部を設け、側板及び懸架部材の孔部を嵌合させることによって、側板に懸架部材を位置決めするようにすれば、側板に対する懸架部材の位置決めを簡単かつ正確に行うことができる。
