Description

【0001】
[産業上の利用分野]
任意の複雑な形状をした薄板を、変形を避けて支持することが要求される、例えば、印刷、配線、溶着等に関する分野。
【0002】
[従来技術]
(1)ロッドにテーパー部を設け、このテーパー部に鋼球を食い込ませるタイプの多点ストッパー。
(2)エァシリンダのピストンロッド外周にブレーキ部材をかんごうし、該ブレーキ部材の外周にゴム製のチュウーブを装着し、該チューブの外周を加圧するタイプの、エァシリンダ用ブレーキ装置。
【0003】
[発明が解決しようとする課題]
本願発明の課題は、複雑、且つ、任意の形状に倣うために、狭い範囲に独立した多数の支持点を可能とする、新規な極めて小型のストッパー機構を提供することである。
【0004】
[課題を解決しようとするための手段]
ストッパーピンの外周に、隙間嵌めで装着する薄肉チューブの端面にフランジ部を一体構造で設けて、このフランジ部にも加圧することにより、薄肉チューブに軸方向の引っ張り弾性変形を生じさせ、この引っ張り弾性変形に基づくチューブ内径の減少を利用し、且つ、薄肉チューブの軸方向の固定を確実にする。又、このフランジ部の弾性変形に伴う、チューブ内径の変形を、ストッパーピンとの固定と開放の両方に有効に利用する。
【0005】
[発明の実施の形態]
図面にしたがつて説明する。
図1は、本願発明の多点支持装置の、部分断面拡大図であり、実際は、ストッパーピン1が等間隔(8mm間隔)に多数並んでいる。
ストッパーピン1はハウジング7にガイドされて、且つ、スプリング3に逆らって軸方向に移行する、5はストッパーである。
ゴム製の薄肉チューブ2は、その内径が、ストッパーピン1の外径と隙間嵌めの状態で、ハウジング7に加工された加圧室8に組み込まれている。
又、薄肉チューブ2の両端面には、エァ圧を受けるフランジ部が、一体構造で設けられている。ここで、薄肉チューブ2の材質について述べると、請求の範囲等に記した、ゴム製とは、ウレタンゴム、ニトリルゴム、等に代表される材質であるが、他の条件次第では、ナイロン等の合成樹脂の使用も考えられる。次に、動作について述べる。
給排気口9から排気された状態では、ストッパーピン1と薄肉チューブ2は隙間嵌めの状態であり、スプリング4により、ストッパー5によって拘束されるまで飛び出している。この状態で、多数のストッパーピン1の上に、複雑な形状のワークをセットすると、それぞれのストッパーピン1が複雑な形状に倣って引っ込む。この状態で、給排気口9から加圧すると、薄肉チューブ2は、軸方向に引っ張られると同時に径方向に圧縮される。
このことで、ストッパーピン1の外周と薄肉チューブ2の内周が摩擦力で固定され、且つ、薄肉チューブ2のフランジ部3がハウジング7の加圧室の端面に、弾性変形を伴って、エァ圧により押し付けられる。
よって、薄肉チューブ2即ちストッパーピン1がハウジング7に、それぞれ、ワークの形状に倣った位置で固定されることになる。
この状態で、ワークの逆面、ストッパーピンと逆側の面に、印刷、配線、溶着、はんだ付け、等が安定して出来ることになる。
次に、ワークを取り外した状態で、給排気口9から排気すると、薄肉チューブ2のチューブ部自体の弾性とフランジ部3の弾性が共に、チューブの内径が広がる方に働き、最初の隙間嵌めの状態になる。
【0006】
[実施例]
ストッパーピンの外径 4mm、 薄肉チューブの肉厚 0・5mm、
チューブのフランジ部外径 7mm、 チューブの軸方向長さ 10mm、
スプリング4の反発力 0・04〜0・06N、 ストッパーピンのストローク12mm、
以上のものを、2列で28本組み込んだ装置で、供給エァ圧 0・4MPaで、実施した結果、それぞれのストッパーピンの支持力として、0・5Nを確認した。
【0007】
[発明の効果]
1、極めて狭い間隔で、多数のピンをそれぞれ任意の位置で固定することが出来き、複雑な形状に倣った支持が可能となる。
2、薄肉チューブに、径方向と同時に軸方向にも加圧することで、安定した弾性変形の繰返しが可能となり、且つ、軸方向のガタの無い固定を可能とする。
3、装置全体の小型化及び、コストの低減に貢献する。

[0001]
[Industrial application fields]
Fields relating to, for example, printing, wiring, welding, etc., where it is required to support a thin plate having an arbitrary complicated shape while avoiding deformation.
[0002]
[Conventional technology]
(1) A multi-point stopper in which a taper portion is provided on the rod, and a steel ball is bitten into the taper portion.
(2) A brake device for an air cylinder in which a brake member is attached to the outer periphery of the piston rod of the air cylinder, a rubber tube is attached to the outer periphery of the brake member, and the outer periphery of the tube is pressurized.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide a novel and extremely small stopper mechanism that enables a large number of independent support points in a narrow range in order to follow complicated and arbitrary shapes.
[0004]
[Means to try to solve the problem]
A flange part is provided on the end surface of the thin tube that is fitted with a clearance fit on the outer periphery of the stopper pin. The reduction of the inner diameter of the tube based on elastic deformation is used, and the axial fixation of the thin tube is ensured. Further, the deformation of the inner diameter of the tube accompanying the elastic deformation of the flange portion is effectively used for both fixing and opening with the stopper pin.
[0005]
[Embodiment of the Invention]
This will be described with reference to the drawings.
FIG. 1 is an enlarged partial cross-sectional view of the multi-point support device of the present invention. Actually, a large number of stopper pins 1 are arranged at regular intervals (8 mm intervals).
The stopper pin 1 is guided by the housing 7 and moves in the axial direction against the spring 3. Reference numeral 5 denotes a stopper.
The rubber thin-walled tube 2 is incorporated in the pressurizing chamber 8 processed into the housing 7 with the inner diameter of the rubber tube 2 fitted to the outer diameter of the stopper pin 1.
Moreover, the flange part which receives an air pressure is provided in the both end surfaces of the thin wall tube 2 by integral structure. Here, the material of the thin-walled tube 2 will be described. In the claims, rubber is a material typified by urethane rubber, nitrile rubber, etc., but depending on other conditions, such as nylon The use of synthetic resins is also conceivable. Next, the operation will be described.
In a state where the air is exhausted from the air supply / exhaust port 9, the stopper pin 1 and the thin tube 2 are in a state of being fitted with a gap, and are protruded by the spring 4 until being restrained by the stopper 5. In this state, when a workpiece having a complicated shape is set on a large number of stopper pins 1, each stopper pin 1 retracts following the complicated shape. When pressure is applied from the air supply / exhaust port 9 in this state, the thin tube 2 is pulled in the axial direction and simultaneously compressed in the radial direction.
As a result, the outer periphery of the stopper pin 1 and the inner periphery of the thin tube 2 are fixed by friction force, and the flange portion 3 of the thin tube 2 is elastically deformed on the end surface of the pressurizing chamber of the housing 7. Pressed by pressure.
Therefore, the thin tube 2, that is, the stopper pin 1 is fixed to the housing 7 at a position following the shape of the workpiece.
In this state, printing, wiring, welding, soldering, and the like can be stably performed on the reverse surface of the workpiece and the surface opposite to the stopper pin.
Next, when the work is removed and the air is exhausted from the air supply / exhaust port 9, both the elasticity of the tube portion itself of the thin tube 2 and the elasticity of the flange portion 3 work in the direction in which the inner diameter of the tube is widened. It becomes a state.
[0006]
[Example]
Stopper pin outer diameter 4mm, thin tube thickness 0.5mm,
Tube flange outer diameter 7mm, tube axial length 10mm,
Spring 4 repulsive force 0.04 to 0.06N, stopper pin stroke 12mm,
As a result of carrying out the above-mentioned apparatus with 28 devices in two rows at a supply air pressure of 0.4 MPa, 0.5 N was confirmed as the supporting force of each stopper pin.
[0007]
[The invention's effect]
1. It is possible to fix a large number of pins at arbitrary positions at extremely narrow intervals, and support according to a complicated shape becomes possible.
2. By applying pressure to the thin tube in the axial direction as well as in the radial direction, stable elastic deformation can be repeated, and fixing without backlash in the axial direction is possible.
3. Contributes to downsizing of the entire device and cost reduction.
