本発明は各種自動機械に使用される各種支持台
のエアースライド及び静止用支持台に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air slide and a stationary support for various types of support used in various automatic machines.
各種自動機械にあつてはワークあるいは治具、
工具類をスライド（移動）させ、さらに所定位置
に静止させる必要が生ずる。 Workpieces or jigs for various automatic machines,
It becomes necessary to slide (move) the tools and then keep them stationary at a predetermined position.
上記スライドにはモーターあるいはシリンダー
等が使用されるが、所定位置に完全に静止させる
ことが困難であつた。 A motor or cylinder is used for the slide, but it is difficult to keep it completely stationary at a predetermined position.
本発明は上記のごとき欠点を除去してなるもの
で、無接触状態でワークあるいは治具、工具類を
載置した支持台をスライドさせ、所定位置に完全
に静止させるよう構成したものである。 The present invention eliminates the above-mentioned drawbacks, and is constructed so that a support base on which a workpiece, jig, or tools are placed can be slid without contact and completely stopped at a predetermined position.
本発明では支持台のスライド時には支持台の下
面からエアーが噴射され、支持台を支持している
ベースとの間に空気膜を構成して支持台を無接触
状態としてスライドさせることができる。 In the present invention, when the support table is slid, air is injected from the lower surface of the support table, and an air film is formed between the support table and the base supporting the support table, so that the support table can be slid in a non-contact state.
したがつて、摺動面の摩耗を全く除去できると
ともに摺動面への潤滑、給油が全く不要となるも

定位置にスライドさせてクランプ装置を働かせ、
支持台を完全に静止させることができる。 Therefore, wear on the sliding surfaces can be completely eliminated, and there is no need to lubricate or oil the sliding surfaces.Furthermore, the force required to slide the support base is small.For example, small, high-precision pulse A motor or the like can be used, making it possible to downsize the device and reduce the cost of the device. Furthermore, slide the support stand into place and activate the clamping device.
The support base can be kept completely still.
本発明では上記クランプ装置として吸着機構が
採用される。 In the present invention, a suction mechanism is employed as the clamp device.

クロン程度浮上させられる。 As a result, compressed air is supplied to the bottom groove 5 through the compressed air supply source 8, piping 10, switching valve 9, piping 13, and vent hole 6, and the support base 1 is floated by about 3 to 5 microns.
その際にはエジエクターポンプ７はもとより、
可撓性シール部材３には給気が行われない。 At that time, not only the ejector pump 7 but also
The flexible seal member 3 is not supplied with air.
したがつて可撓性シール部材３は扁平状に収縮
しており、支持台１のスライドを邪魔することは
ない。 Therefore, the flexible seal member 3 is contracted into a flat shape and does not interfere with the sliding of the support base 1.
支持台１のスライドは第５図示のごとく、タイ
ミングベルト１６を使用してもよく、第７図示の
ごとく手動でもよく、さらに第６図示のごとく、

Ｂに圧着する。 As a result, the supply of compressed air to the groove 5 is stopped, the support stand 1 is placed on the base B, and the compressed air is supplied to the edge via the compressed air supply source 8, piping 10, switching valve 9, and piping 11. It is supplied to the supply nozzle 7a of the Ector pump 7, and further supplied to the interior of the flexible seal member 3 via the piping 12 and the vent hole 4, inflating the flexible seal member 3 and press-fitting it to the base B.
そして、その後の圧縮空気は全てエジエクター
ポンプ７の供給ノズル７ａに供給され、その内部
の隔室７ｂが負圧となる。 All of the compressed air thereafter is supplied to the supply nozzle 7a of the ejector pump 7, and the internal compartment 7b becomes negative pressure.
その結果、管路１４、通気孔６を介して溝５部
の空気が吸気され、支持台１の底面がベースＢに
吸着し完全静止させられるものである。 As a result, the air in the groove 5 is sucked in through the conduit 14 and the ventilation hole 6, and the bottom surface of the support base 1 is attracted to the base B, making it completely stationary.
上記吸着は従来の可撓性部材からなる吸盤と異
