Description

本発明は表面加工ツールに対するほこり吸引システムの２つの長さ部分を接続するための旋回コネクタに関する。   The present invention relates to a swivel connector for connecting two lengths of a dust suction system to a surface machining tool.

加工ツールによって環境内に散乱されるほこりに起因する問題は周知である。このようなほこりを吸引により除去することが可能であれば、ツールの動作状態が改善されるとともに、オペレータの作業環境も改善される。例えば、一例として、ほこりの吸引無しで、閉ざされた環境内で動作するオービタルポリッシャを想像されたい。   Problems due to dust scattered into the environment by processing tools are well known. If such dust can be removed by suction, the operating state of the tool is improved and the working environment of the operator is also improved. For example, as an example, imagine an orbital polisher operating in a closed environment without dust suction.

従来技術に見られる無視することのできない作業上の利益および存在価値にもかかわらず、吸引システムとツールとの組み合わせによっては、吸引管に煩雑さが追加されたり、これらの位置決めの際の柔軟性の欠如のために、人間工学上の問題が引き起こされることがある。事実、従来技術によるコネクタにおいては、吸引管は、たった１つの位置、典型的には、吸引平面に対して垂直あるいは並行のいずれの方向にしか配置することが許されない。   Despite the non-negligible operational benefits and value found in the prior art, some combinations of suction systems and tools add complexity to the suction tubes and provide flexibility in positioning these The lack of can cause ergonomic problems. In fact, in prior art connectors, the suction tube is only allowed to be placed in one position, typically either perpendicular or parallel to the suction plane.

この構成の典型的な短所は、ツールを吸引管の方向に操縦する際の操作性の低さにある。単に例示として、狭苦しい環境内で動作しなければならないオービタルポリッシャと、作業表面に対して垂直の吸引管アウトレットを有することができることの長所を想像されたい。同様に、ポリッシャは、好ましくは、その軸が壁に対して平行なコネクタを利用することで、２つの接近した壁の間で動作するために用いることもできる。これら両方の状況において、吸引管コネクタの方向を変更できる可能性が存在しない限り、ポリッシャは、機能できないことは明白である。   A typical disadvantage of this arrangement is its low operability when manipulating the tool in the direction of the suction tube. By way of example only, imagine the advantages of having an orbital polisher that must operate in a harsh environment and a suction tube outlet perpendicular to the work surface. Similarly, a polisher can also be used to operate between two adjacent walls, preferably utilizing a connector whose axis is parallel to the wall. Obviously, in both of these situations, the polisher cannot function unless there is a possibility to change the orientation of the suction tube connector.

本発明の目的は、従って、このような短所を克服することにある。   The object of the present invention is therefore to overcome these disadvantages.

本発明によると、この目的は、加工ツールに結合された吸引システムに対する旋回コネクタを介して達成される。   According to the invention, this object is achieved via a pivot connector for a suction system coupled to the processing tool.

本発明に従うコネクタは、２つのスリーブを含み、これらは互いに、吸引の方向に対して、とりわけ、４５°を向く、傾斜した旋回軸の周りを、各々のこれに対して垂直な旋回平面に沿って回転可能である。１つのスリーブは、吸引ホースに接続され、他方のスリーブは、ツール側に、特定の物質を吸引するために接続される。これら２つのスリーブ間のこのタイプの結合のために、各々の軸の相対位置を、必要に応じて、連続的なやり方にて、各々の軸が一致するか、あるいは互いに９０°だけ傾斜するように、選択することが可能となる。   The connector according to the invention comprises two sleeves, which are oriented with respect to the direction of suction with respect to each other, in particular around an inclined pivot axis, which is oriented at 45 °, along a pivot plane perpendicular to each other. And can be rotated. One sleeve is connected to the suction hose and the other sleeve is connected to the tool side to suck a specific substance. Due to this type of coupling between the two sleeves, the relative position of each axis is adjusted in a continuous manner, if necessary, so that each axis coincides or is inclined by 90 ° with respect to each other. It becomes possible to select.

本発明のこれらおよび他の特徴が、添付の図面に非制限的な例として示されている、本発明の実施例の以下の詳細な説明から明白となるものである。   These and other features of the present invention will become apparent from the following detailed description of embodiments of the invention, illustrated by way of non-limiting example in the accompanying drawings.

図面は本発明に従う第１のスリーブ１と第２のスリーブ２を含むコネクタ５０を示す。図１にはコネクタ５０および旋回連結器５１を介して管に接続されたポリッシャ５２が示されるが、この管自身は次に吸引マシーンに接続される。   The drawing shows a connector 50 comprising a first sleeve 1 and a second sleeve 2 according to the present invention. FIG. 1 shows a polisher 52 connected to a tube via a connector 50 and a swivel coupler 51, which in turn is connected to a suction machine.

第１のスリーブ１について図４および５を参照しながら説明されるが、ここには中空の円筒状の本体３が示されており、これは吸引マシーンに接続するための１つの自由端４と、１つの旋回端５とを備える。この旋回端５は、環状の部分７に終端する円筒状の突出部６から形成され、この環状の部分７は、直径において円筒状の部分６より広く、そして終端部分において直径において狭くなる。旋回端５の軸は、この純粋に例示的で非制限的な例においては、第１のスリーブ１の円筒セクション３の軸に対して４５°の方向を向く。この円筒状の突出部のもう１つの特徴と、環状の部分７のそれは、円筒状の部分の直径に沿って配置された対のノッチ８を有することであり、これは円筒状の部分６および環状の部分７を四分円に分割するが、これは、以下でより明白となるように、第２のスリーブ上の対応する空洞と咬み合うべき旋回端５の柔軟性を増加させるという目的と、スリーブ間の相対的な回転の動作が単にノッチ８と第２のスリーブ上の対応する突出部との咬み合いに起因するロッキングトルクに打ち勝つことで達成可能となるという目的の二重の目的を果たす。   The first sleeve 1 will be described with reference to FIGS. 4 and 5, in which a hollow cylindrical body 3 is shown, which has one free end 4 for connection to a suction machine and And one swivel end 5. This swivel end 5 is formed from a cylindrical projection 6 that terminates in an annular part 7 that is wider in diameter than the cylindrical part 6 and narrower in diameter at the terminal part. The axis of the pivot end 5 is oriented in the direction of 45 ° with respect to the axis of the cylindrical section 3 of the first sleeve 1 in this purely exemplary and non-limiting example. Another feature of this cylindrical protrusion and that of the annular portion 7 is that it has a pair of notches 8 arranged along the diameter of the cylindrical portion, which is the cylindrical portion 6 and Dividing the annular part 7 into quadrants, which aims to increase the flexibility of the swivel end 5 to be engaged with the corresponding cavity on the second sleeve, as will become more apparent below. The dual purpose of the objective is that the relative rotational movement between the sleeves can be achieved simply by overcoming the locking torque resulting from the engagement of the notches 8 and the corresponding protrusions on the second sleeve. Fulfill.

第２のスリーブ２が図６、７および８との関連で説明される。中空の円筒状の本体９が示されているが、これは加工ツールとの接続のための１つの自由端１０と、旋回端１１とを有する。旋回端１１は先細の孔１２を含み、この直径は、円筒状の突出部６および環状の部分７を、この中に、組み立てのために押し込むことができるように、内側に向かって細くなり、そして、この先細の孔は、少なくとも一対の突出部１３を有し、この突出部１３は、先細の孔１２の直径を、従って開口サイズを少し低減させるような寸法を有する。この第２のスリーブの突出部１３は、第１のスリーブの対応するノッチ８と、これらスリーブ間の相対的な回転の動作が、単に軽く押すだけで達成可能となるようなやり方にてかみ合い、こうして、例えば、これに取り付けられたマシーンが動作している間の自由な無制御の回転が阻止される。旋回端１１のもう１つの根本的な特徴は、この旋回端の軸は、この純粋に例示的な、非制限的な例においては、第１のスリーブ１の中空の円筒状の本体９の軸に対して、４５°方向を向くことである。   The second sleeve 2 is described in connection with FIGS. A hollow cylindrical body 9 is shown, which has one free end 10 for connection with a processing tool and a swivel end 11. The swivel end 11 includes a tapered hole 12 whose diameter tapers inward so that the cylindrical protrusion 6 and the annular portion 7 can be pushed into it for assembly, The tapered hole has at least a pair of projecting portions 13, and the projecting portions 13 have dimensions that slightly reduce the diameter of the tapered hole 12, and thus the opening size. This protrusion 13 of the second sleeve meshes with the corresponding notch 8 of the first sleeve in such a way that the relative rotational movement between the sleeves can be achieved with a simple press, Thus, for example, free and uncontrolled rotation while the machine attached to it is operating is prevented. Another fundamental feature of the swivel end 11 is that this swivel end axis is, in this purely exemplary, non-limiting example, the axis of the hollow cylindrical body 9 of the first sleeve 1. The direction is 45 °.

組立て時においては、第１のスリーブ１の円筒状の部分６および環状の部分７が、第２のスリーブ２の先細の孔１２内に、突出部１３とノッチ８とがうまく合うように注意しながら押し込められる。旋回端５および１１の２つの軸は、こうして一致し、こうして単一の旋回軸１４が形成され、第１のスリーブ１と第２のスリーブ２は旋回平面５３に沿って互いに結合されるが、この平面５３はこれら２つのスリーブの軸に対しては傾斜し、旋回軸１４に対しては垂直となる。突出部１３は、好ましくは、例えば、図６および８において最も明白なように、対角軸と一致するように配置され、他方、ノッチ８は、図４において最も明白なように、互いに直交する２つの対角軸と一致するように配置され、この結果として、本発明の目的に従って、２つの動作位置、すなわち、スリーブの軸が平行な位置と、スリーブの軸が垂直の位置において、一時的なロックが形成される。   At the time of assembly, care is taken that the cylindrical portion 6 and the annular portion 7 of the first sleeve 1 fit well with the protrusion 13 and the notch 8 in the tapered hole 12 of the second sleeve 2. It can be pushed in. The two axes of the pivot ends 5 and 11 are thus coincident, thus forming a single pivot axis 14 and the first sleeve 1 and the second sleeve 2 are coupled together along the pivot plane 53, This plane 53 is inclined with respect to the axes of these two sleeves and is perpendicular to the pivot axis 14. The protrusions 13 are preferably arranged to coincide with the diagonal axis, for example, as most apparent in FIGS. 6 and 8, while the notches 8 are orthogonal to each other, as is most apparent in FIG. Arranged so as to coincide with the two diagonal axes, and as a result, according to the purpose of the present invention, in two operating positions, i.e. a position where the sleeve axis is parallel and a position where the sleeve axis is vertical Lock is formed.

もし必要であるときは、０°および９０°以外の角度の追加の動作位置を、適当なロッキング要素を用い、これをこれら２つのスリーブ１および２に適用することで、提供することもできる。   If necessary, additional operating positions at angles other than 0 ° and 90 ° can be provided by using appropriate locking elements and applying them to these two sleeves 1 and 2.

更に、もう１つの実施例においては、スリーブ２は、ツール５２と一体化して形成することもできる。   Furthermore, in another embodiment, the sleeve 2 can be formed integrally with the tool 52.

図１０は、本発明に従うコネクタのもう１つの実施例を示すが、ここでは、第１と第２のスリーブ１と２は、各々の中空の円筒状の本体３と９を有し、これらは同一の自由端４と１０を有し、この中に同一あるいは異なる直径のブッシング２１、２２が回転可能に収容される。コネクタ５０は、こうして、吸引マシーンおよび加工ツールに回転可能に接続可能である。   FIG. 10 shows another embodiment of a connector according to the invention, in which the first and second sleeves 1 and 2 have respective hollow cylindrical bodies 3 and 9, which are Bushings 21 and 22 having the same free ends 4 and 10 and having the same or different diameters are rotatably accommodated therein. The connector 50 can thus be rotatably connected to the suction machine and the processing tool.
