Description

この発明は、一方の板金を他方の板金に取付ける際の位置決め構造とそれを用いて形成されてなる画像形成装置に関する。   The present invention relates to a positioning structure for attaching one sheet metal to the other sheet metal and an image forming apparatus formed using the same.

例えば、画像形成装置のようにその本体が各種の板金から形成されている場合には、これらの板金同士を、図６に示すように、互いに組付ける際に、位置決めの目安となる板金の位置決め構造が該板金に備えられていることが、作業性の観点から好ましい。そして、従来の板金の位置決め構造１０１は、図７に示すように、一方の板金１０２ａに形成された薄板状の突出部１０３を、他方の板金１０２ｂに形成された開口部１０４の内部に対向して設けられた２つの円弧状の膨出部１０５ａが、突出部１０３を厚み方向に挟持することで板金１０２同士の位置決めを行うものが考案されている。また、図８に示すように、一方の板金１０２ａに形成された薄板状の突出部１０３を、他方の板金１０２ｂに形成された開口部１０４の内部に対向して設けられた円弧状の膨出部１０５ａと水平部を有する膨出部１０５ｂが、突出部１０３を厚み方向に挟持することで板金１０２同士の位置決めを行うものが考案されている。   For example, in the case where the main body is formed of various types of sheet metal as in the image forming apparatus, as shown in FIG. It is preferable from the viewpoint of workability that the sheet metal is provided with a structure. In the conventional sheet metal positioning structure 101, as shown in FIG. 7, the thin plate-like protrusion 103 formed on one sheet metal 102a is opposed to the inside of the opening 104 formed on the other sheet metal 102b. Have been devised in which two arcuate bulged portions 105a provided to position the metal plates 102 by sandwiching the protruding portion 103 in the thickness direction. Further, as shown in FIG. 8, a thin plate-like protruding portion 103 formed on one sheet metal 102a is swelled in an arc shape provided facing the inside of an opening 104 formed on the other sheet metal 102b. The bulging part 105b which has the part 105a and a horizontal part is devised what positions the sheet metal 102 by pinching the protrusion part 103 in the thickness direction.

そして、これらの図７及び図８に示す開口部１０４を形成するためには、打抜きプレス加工、すなわち、図９に示すような、目的の開口部１０４の形状と略同形状に形成された打抜き型１０６を用いて、プレス機により板金を打抜くことにより開口部１０４を形成する方法が用いられている（例えば特許文献１）。   In order to form the opening 104 shown in FIGS. 7 and 8, punching press processing, that is, punching formed in substantially the same shape as the target opening 104 as shown in FIG. A method of forming the opening 104 by punching a sheet metal with a press using a mold 106 is used (for example, Patent Document 1).

特許３２１４１７７号公報Japanese Patent No. 3214177

しかし、例えば、画像形成装置に使用されるような板金１０２は非常にその厚みが薄く、一方の板金１０２ａに形成される突出部１０３の厚みも小さくなる。そのため、図７や図８に示すような、開口部１０４内に形成される膨出部１０５の間隔も非常に小さいものとなり、相対向する膨出部の離間距離が最小となる狭窄部分１０７を有する開口部１０４を形成するためには、図９に示すような、略同形状の狭窄箇所１０８を有する打抜き型１０６が必要となる。   However, for example, the sheet metal 102 used in the image forming apparatus is very thin, and the thickness of the protrusion 103 formed on one sheet metal 102a is also small. Therefore, as shown in FIG. 7 and FIG. 8, the interval between the bulging portions 105 formed in the opening 104 is very small, and the constricted portion 107 in which the distance between the bulging portions facing each other is minimized. In order to form the opening 104 having the punching die 106, a punching die 106 having a narrowed portion 108 having substantially the same shape as shown in FIG. 9 is required.

しかし、狭窄箇所１０８を有する打抜き型１０６を作成することは、技術上可能であるが、間隔の小さい該狭窄箇所１０８の物理的な強度が弱くなる。そのため、それらを繰返し使用した際には、図９に示すように、狭窄箇所１０８のエッジ部１０９が磨耗や破損することがある。そして、板金１０２を打抜き加工する際に、エッジ部１０９が磨耗や破損した打抜き型１０６を使用した場合には、打抜き加工後の開口部１０４の狭窄部分１０７に、図９に示すような、バリ１１０が発生したり、打抜くことが不可能になる等の成型不良が発生する問題がある。   However, although it is technically possible to produce the punching die 106 having the constricted portion 108, the physical strength of the constricted portion 108 having a small interval is weakened. Therefore, when they are used repeatedly, as shown in FIG. 9, the edge portion 109 of the narrowed portion 108 may be worn or damaged. When punching the sheet metal 102, if a punching die 106 whose edge portion 109 is worn or damaged is used, a burrs as shown in FIG. 9 are formed in the narrowed portion 107 of the opening 104 after punching. There is a problem in that molding defects such as 110 occur or it becomes impossible to punch.

また、図７に示すような、開口部１０４は、薄板状の突出部１０３を挟持する際に、該突出部１０３の厚み方向が、対向する２つの円弧状の膨出部１０５ａにしか保持されていない。そのため、２点のみで突出部１０３の厚み方向が支持されており、開口部１０４と突出部１０３との幅方向において組付け誤差等により若干の隙間が生じた際には、図７に示すように、開口部１０４に対して突出部１０３が回転可能、すなわち、他方の板金１０２ｂに対して一方の板金１０２ａが回転する可能性がある。結果として、板金１０２同士の位置決めを正確に行うことができないといった問題が生じる。   Moreover, as shown in FIG. 7, when the opening 104 is sandwiched between the thin plate-like protrusions 103, the thickness direction of the protrusions 103 is held only by the two arcuate bulging portions 105a facing each other. Not. For this reason, the thickness direction of the protrusion 103 is supported only at two points. When a slight gap occurs due to an assembly error or the like in the width direction between the opening 104 and the protrusion 103, as shown in FIG. In addition, the protrusion 103 can rotate with respect to the opening 104, that is, one sheet metal 102a can rotate with respect to the other sheet metal 102b. As a result, there arises a problem that the sheet metals 102 cannot be positioned accurately.

また、板金１０２に使用される金属は、例えば、画像形成装置等の電子機器を始めとした各分野においては、機器本体の軽量化に伴いこれらに使用される板金１０２の厚みが薄くなると共に、該板金１０２の強度も高くなってきている。さらに、前記機器本体の小型化に伴い、各板金１０２の形状が小さくなり、加工精度も求められている。しかし、図７や図８に示すような、板金の位置決め構造１０１を作成する際には、突出部１０３の厚みと略同等の狭窄箇所１０８を有する打抜き型１０６が必要となるため、これらの要求を満たすことが困難である。   The metal used for the sheet metal 102 is, for example, in each field including an electronic device such as an image forming apparatus. The strength of the sheet metal 102 is also increasing. Furthermore, with the miniaturization of the device main body, the shape of each sheet metal 102 is reduced, and processing accuracy is also required. However, when creating the sheet metal positioning structure 101 as shown in FIGS. 7 and 8, a punching die 106 having a narrowed portion 108 substantially equal to the thickness of the protruding portion 103 is required. It is difficult to satisfy.

この発明は、上記のような種々の課題を解決することを目的としてなされたものであって、打抜きプレス加工により開口部を形成する際に用いる打抜き型の最小肉厚箇所の肉厚を大きくすることができ、磨耗や破損を防ぎ、該開口部の加工精度を向上させ、さらに確実に板金同士の位置決めを行うことのできる、板金の位置決め構造とそれを用いた画像形成装置に関する。   This invention was made for the purpose of solving the various problems as described above, and increases the thickness of the minimum thickness portion of the punching die used when forming the opening by punching press processing. The present invention relates to a sheet metal positioning structure and an image forming apparatus using the same, which can prevent wear and breakage, improve the processing accuracy of the opening, and can reliably position the metal sheets.

上記目的を達成するために、請求項１記載の板金の位置決め構造は、一方の板金に形成された薄板状の突出部を、他方の板金に形成された開口部の内部に対向して設けられた膨出部が厚み方向に挟持することで板金同士の位置決めを行う板金の位置決め構造において、前記膨出部が、前記突出部の一方の面に当接する少なくとも１つの一方側膨出部と、該一方側膨出部を挟んだ左右両側に該一方側膨出部と対向するように膨出されて、前記突出部の他方の面に当接する他方側膨出部とを具備することを特徴としている。   In order to achieve the above object, the sheet metal positioning structure according to claim 1 is provided with a thin plate-like protrusion formed on one sheet metal facing the inside of an opening formed on the other sheet metal. In the sheet metal positioning structure in which the sheet metal is positioned by sandwiching the bulged part in the thickness direction, the bulged part is at least one one-side bulged part that comes into contact with one surface of the protruding part, The left and right sides sandwiching the one side bulging portion are bulged so as to face the one side bulging portion, and the other side bulging portion is in contact with the other surface of the protruding portion. It is said.

請求項２記載の板金の位置決め構造は、前記開口部の幅方向の長さが、前記突出部の幅方向の長さと略等しく形成されていることを特徴としている。   The sheet metal positioning structure according to claim 2 is characterized in that a length of the opening in the width direction is formed substantially equal to a length of the protrusion in the width direction.

請求項３記載の画像形成装置は、請求項１又は請求項２記載の板金の位置決め構造を用いて形成されてなることを特徴としている。   An image forming apparatus according to a third aspect is formed by using the sheet metal positioning structure according to the first or second aspect.

請求項１記載の板金の位置決め構造によれば、一方側膨出部と他方側膨出部との距離を、突出部の厚みよりも大きくすることができ、打抜きプレス加工により開口部を形成する際に使用する打抜き型における、相対向する膨出部の離間距離が最小となる狭窄箇所、すなわち、最小肉厚箇所の肉厚を大きく設計することができる。   According to the sheet metal positioning structure of claim 1, the distance between the one side bulging portion and the other side bulging portion can be made larger than the thickness of the protruding portion, and the opening is formed by punching press processing. In the punching die used at this time, the thickness of the narrowed portion where the separation distance between the bulging portions facing each other is minimized, that is, the minimum thickness portion can be designed to be large.

そのため、打抜き型の物理的強度が高くなり、該打抜き型を繰返し使用したとしても、狭窄箇所のエッジ部分が磨耗や破損することがなく、形成された開口部にバリが発生したり、打抜くことが不可能になる等の成型不良が発生することがない。さらに、常に精度の高い開口部を形成することができるだけでなく、板金が使用される機器等の小型化、軽量化に対応した、板金の厚みが薄く、高強度、高精度、小形状が要求される箇所や、部材にも使用することができる。また、開口部に対して突出部が回転、すなわち、他方の板金に対して一方の板金が回転することがなく、結果として、板金同士の位置決めを正確に行うことができる。   Therefore, the physical strength of the punching die is increased, and even if the punching die is used repeatedly, the edge portion of the narrowed portion is not worn or damaged, and the formed opening is burred or punched. This prevents the occurrence of molding defects such as impossible. Furthermore, not only can the openings with high accuracy be formed at all times, but the thickness of the sheet metal is thin, high strength, high accuracy, and small shape are required in order to reduce the size and weight of equipment that uses sheet metal. It can also be used for parts and members to be used. In addition, the protrusion does not rotate with respect to the opening, that is, one sheet metal does not rotate with respect to the other sheet metal, and as a result, the sheet metals can be accurately positioned.

請求項２記載の板金の位置決め構造によれば、突出部を開口部に挿通した際には、開口部の幅方向の両側面に、突出部の幅方向の両側面が当接する。これにより、上述の効果に加えて、板金同士の位置決めを行う際には、開口部に突出部を挿通するが、その場合にも該開口部に挿通された突出部が幅方向にずれることがなく、すなわち、他方の板金に対して一方の板金が幅方向にずれることがないため、結果として板金の位置決めをより正確に行うことができる。   According to the sheet metal positioning structure of the second aspect, when the projecting portion is inserted into the opening, both side surfaces in the width direction of the projecting portion are brought into contact with both side surfaces in the width direction of the opening. Thereby, in addition to the above-mentioned effect, when positioning the metal plates, the protruding portion is inserted into the opening portion. In this case, the protruding portion inserted through the opening portion may be shifted in the width direction. In other words, since one sheet metal does not shift in the width direction with respect to the other sheet metal, the sheet metal can be positioned more accurately as a result.

請求項３記載の画像形成装置によれば、請求項１又は請求項２記載の板金の位置決め構造を用いて形成されていることで、上述の効果に加えて、該画像形成装置に使用されている板金の組付けを正確且つ迅速に行うことができるため、生産効率を向上することができる。また、打抜き型の磨耗や損傷を防ぐことができ、さらに、開口部の成型不良が生じることがなく打抜きプレス加工の歩留まりを向上できるので、画像形成装置の生産コストを削減することができる。   According to the image forming apparatus of the third aspect, since the sheet metal positioning structure according to the first or second aspect is used, in addition to the above-described effects, the image forming apparatus is used in the image forming apparatus. Since the sheet metal can be assembled accurately and quickly, the production efficiency can be improved. Further, wear and damage of the punching die can be prevented, and further, the yield of punching press working can be improved without causing defective molding of the opening, so that the production cost of the image forming apparatus can be reduced.

以下、この発明の実施形態に係る板金の位置決め構造１、及びこれを用いて形成されてなる画像形成装置２について説明する。本発明に係る板金の位置決め構造１は、図４に示すように、一方の板金３ａに形成された薄板状の突出部４を、他方の板金３ｂに形成された開口部５の内部に対向して設けられた膨出部６が厚み方向に挟持することで板金３同士の位置決めを行う板金の位置決め構造１において、前記膨出部６が、前記突出部４の一方の面に当接する少なくとも１つの一方側膨出部６ａと、該一方側膨出部６ａを挟んだ左右両側に該一方側膨出部６ａと対向するように膨出されて、前記突出部４の他方の面に当接する他方側膨出部６ｂとを具備している。そして、必要に応じて、前記開口部５の幅方向の長さが、前記突出部４の幅方向の長さと略等しく形成されている。   Hereinafter, a sheet metal positioning structure 1 according to an embodiment of the present invention and an image forming apparatus 2 formed using the same will be described. As shown in FIG. 4, the sheet metal positioning structure 1 according to the present invention has a thin plate-like protrusion 4 formed on one sheet metal 3a facing the inside of an opening 5 formed on the other sheet metal 3b. In the sheet metal positioning structure 1 for positioning the sheet metals 3 by sandwiching the bulging part 6 provided in the thickness direction, the bulging part 6 contacts at least one surface of the projecting part 4. One side bulging portion 6a and the left and right sides sandwiching the one side bulging portion 6a are bulged so as to face the one side bulging portion 6a and come into contact with the other surface of the protruding portion 4 And the other side bulging portion 6b. And the length of the width direction of the said opening part 5 is formed substantially equal to the length of the width direction of the said protrusion part 4 as needed.

そして、上述のように構成される、板金の位置決め構造１を用いて、図１に示すように、画像形成装置２が形成されている。そして、例えば、板金の位置決め構造１は、図２に示すように、画像形成手段を収容してなる画像形成装置２本体の上面に設けられた板金３ａ（一方の板金）と、画像読取手段を収容してなる筺体７の底面を受ける板金３ｂ（他方の板金）との位置決めに用いられている。   An image forming apparatus 2 is formed using the sheet metal positioning structure 1 configured as described above, as shown in FIG. For example, as shown in FIG. 2, the sheet metal positioning structure 1 includes a sheet metal 3a (one sheet metal) provided on the upper surface of the main body of the image forming apparatus 2 containing the image forming means, and an image reading means. It is used for positioning with the sheet metal 3b (the other sheet metal) that receives the bottom surface of the housing 7 that is housed.

前記突出部４は、一方の板金３ａに薄板状に形成されている。そして、本発明の実施形態においては、突出部４は、図３に示すように、切込み加工や曲げ加工等のプレス加工により、略平面状の一方の板金３ａに切込みを入れ、該一方の板金３ａの水平面部から略垂直方向に立上がるように形成されている。そのため、図４に示すように、突出部４の厚みＳは、使用される一方の板金３ａの厚みに依存している。また、突出部４が形成されている位置は、本発明の実施形態においては、図３に示すように、一方の板金３ａの略垂直に折り曲げられた箇所の端部に形成されているが、該突出部４の形成される位置は、一方の板金３ａの平面内部に形成されていてもよい。また、突出部４の形成方法は、本発明の実施形態のようにプレス加工に限定されるものではなく、略平面状の一方の板金３ａに対して略垂直方向に溶接等によって別途薄板状の板金を取付けるようにしてもよく適宜変更することが可能である。   The protrusion 4 is formed in a thin plate shape on one sheet metal 3a. And in embodiment of this invention, as shown in FIG. 3, the protrusion part 4 cuts into the substantially planar one sheet metal 3a by press processes, such as a cutting process and a bending process, and this one sheet metal. It is formed so as to rise in a substantially vertical direction from the horizontal surface portion 3a. Therefore, as shown in FIG. 4, the thickness S of the protrusion part 4 is dependent on the thickness of the one sheet metal 3a used. Further, in the embodiment of the present invention, the position where the protruding portion 4 is formed is formed at the end portion of the portion bent substantially vertically of one sheet metal 3a, as shown in FIG. The position where the protrusion 4 is formed may be formed inside the plane of one sheet metal 3a. In addition, the method of forming the protrusions 4 is not limited to the press work as in the embodiment of the present invention, and a separate thin plate shape is formed by welding or the like in a substantially vertical direction with respect to the substantially flat sheet metal 3a. A sheet metal may be attached and can be appropriately changed.

前記開口部５は、図４に示すように、略矩形状に形成された該開口部５の内部に対向して設けられた膨出部６により前記突出部４を厚み方向に挟持している。そして、開口部５には該開口部５の厚み方向の一方面８側に少なくとも２つの一方側膨出部６ａが形成されると共に、該一方面８側の互いに隣接する前記一方側膨出部６ａ間の他方面９側に少なくとも１つの他方側膨出部６ｂが形成されている。そして、本発明の実施形態においては、図４に示すように、開口部５の厚み方向の一方面８側に２つの円弧状の一方側膨出部６ａと、該一方側膨出部６ａの間であって他方面９側に１つの円弧状の他方側膨出部６ｂが形成されている。   As shown in FIG. 4, the opening 5 sandwiches the protruding portion 4 in the thickness direction by a bulging portion 6 provided facing the inside of the opening 5 formed in a substantially rectangular shape. . The opening 5 is formed with at least two one-side bulges 6a on the one surface 8 side in the thickness direction of the opening 5, and the one-side bulges adjacent to each other on the one surface 8 side. At least one other side bulging portion 6b is formed on the other surface 9 side between 6a. In the embodiment of the present invention, as shown in FIG. 4, two arc-shaped one side bulging portions 6 a on the one surface 8 side in the thickness direction of the opening 5, and the one side bulging portion 6 a One arcuate other side bulging portion 6b is formed on the other surface 9 side.

また、これらの膨出部６が形成されてなる開口部５は、打抜きプレス加工等により形成されているため、加工に使用される打抜き型は該開口部５の形状と略同形状となる。そのため、図４に示すように、膨出部６を成形することで、突出部４の厚みＳに対して、開口部５における相対向する膨出部の離間距離が最小となる部分である狭窄部分の幅Ｔを大きく形成することが可能となり、打抜き型の最小肉厚箇所の肉厚を大きくすることで、該打抜き型のエッジ部分の磨耗や損傷を防ぐことができ、また、板金３の厚みが小さくなった際にも精度よく開口部５を形成することができる。   Moreover, since the opening 5 formed with these bulging portions 6 is formed by punching press processing or the like, the punching die used for processing has substantially the same shape as the shape of the opening 5. Therefore, as shown in FIG. 4, by forming the bulging portion 6, a narrowing that is a portion where the separation distance of the bulging portions facing each other in the opening 5 is minimum with respect to the thickness S of the protruding portion 4. The width T of the portion can be increased, and by increasing the thickness of the minimum thickness portion of the punching die, wear and damage of the edge portion of the punching die can be prevented. The opening 5 can be formed with high accuracy even when the thickness is reduced.

また、図４に示す開口部５における、側面１０と膨出部６の間や、互いに隣接する一方側膨出部６ａの間等を、図５に示す開口部５のように、ほぼ曲線で形成することで、該開口部５を形成するために使用する打抜き型の磨耗や損傷を防ぐことができる。   Further, in the opening 5 shown in FIG. 4, the space between the side surface 10 and the bulging portion 6 or between the adjacent one-side bulging portions 6a is substantially curved like the opening 5 shown in FIG. By forming, the wear and damage of the punching die used for forming the opening 5 can be prevented.

そして、膨出部６の形状は、図４に示す円弧状や、図５に示す角がなく丸みを帯びた形状であるほうが、開口部５を形成する際に用いられる打抜き型の磨耗や損傷が生じにくく好適であるが、これらの形状は本発明の実施形態に限定されるものではなく、適宜変更することができる。また、一方面８側の２つの一方側膨出部６ａに対する他方面９側の１つの他方側膨出部６ｂの位置は、該２つの一方側膨出部６ａの略中央であって他方面９側に１つの他方側膨出部６ｂが形成されていることが、狭窄部分の幅Ｔを大きくすることができ、結果として、打抜き型の最小肉厚箇所の肉厚を大きくすることができるため好ましいが、これらの配置は適宜変更することができる。   The shape of the bulging portion 6 is worn or damaged in the punching die used when forming the opening 5 if the arc shape shown in FIG. 4 or the rounded shape shown in FIG. However, these shapes are not limited to the embodiments of the present invention, and can be appropriately changed. The position of one other side bulging portion 6b on the other surface 9 side with respect to the two one side bulging portions 6a on the one surface 8 side is substantially the center of the two one side bulging portions 6a and the other surface The fact that one other-side bulging portion 6b is formed on the 9 side can increase the width T of the narrowed portion, and as a result, the thickness of the minimum thickness portion of the punching die can be increased. Therefore, although it is preferable, these arrangements can be changed as appropriate.

そして、上述のように形成され膨出部６に挟持された突出部４は、厚み方向に移動することなく、また、回転することもない。さらに、本発明の実施形態においては、図４や図５に示すように、前記開口部５の幅方向の長さが、前記突出部４の幅方向の長さと略等しく形成されている。そのため、開口部５の膨出部６に挟持された突出部４が、開口部５の幅方向の両側面１０に当接保持されるため該突出部４が幅方向にも移動することもなく、正確に板金３同士の位置決めを行うことができるのである。   And the protrusion part 4 formed as mentioned above and clamped by the bulging part 6 does not move in the thickness direction, and does not rotate. Furthermore, in the embodiment of the present invention, as shown in FIGS. 4 and 5, the length of the opening 5 in the width direction is formed substantially equal to the length of the protrusion 4 in the width direction. For this reason, since the protrusions 4 sandwiched between the bulging portions 6 of the opening 5 are held in contact with both side surfaces 10 of the opening 5 in the width direction, the protrusion 4 does not move in the width direction. Thus, it is possible to accurately position the metal plates 3 with each other.

また、その他にも図２に示すような、画像形成装置２本体の側面部１１等にも板金３が使用されており、このような場所に関しても上述したような板金の位置決め構造１を用いて、板金３同士の位置決めを行うことができる。このように、板金の位置決め構造１は、画像形成装置２の各種部分に使用される板金３同士の位置決めだけでなく、例えばパソコンのような他の電子機器等にも適宜使用することができる。   In addition, as shown in FIG. 2, the sheet metal 3 is also used for the side surface portion 11 and the like of the main body of the image forming apparatus 2, and the above-described sheet metal positioning structure 1 is also used for such a place. The positioning between the sheet metals 3 can be performed. As described above, the sheet metal positioning structure 1 can be used not only for positioning the sheet metals 3 used in various parts of the image forming apparatus 2 but also for other electronic devices such as personal computers.

この発明の板金の位置決め構造は、画像形成装置だけでなく、例えばパソコン等の電子機器、さらには、車や工作機械等にも適用することが可能である。   The sheet metal positioning structure of the present invention can be applied not only to an image forming apparatus, but also to electronic devices such as personal computers, vehicles, machine tools, and the like.
