Description
【０００１】[0001]
本考案は、特に三次元測定器のような高速で動く精密機器を支持するのに好 適な空気ばね装置に関する。 The present invention relates to an air spring device suitable for supporting precision instruments that move at high speed, such as a coordinate measuring machine.
【０００２】[0002]
従来から一つの空気室を備えた空気ばね本体を、底板により下端開口面を気 密に閉塞した中空ゴム体により構成し、この空気ばね本体に配管を介して高さ調 整弁を連結し、この高さ調整弁に空気源を連結してなる空気ばね装置がある。 この空気ばね装置は、空気ばね本体と高さ調整弁とを並列配置し、空気ばね本 体の空気室内に圧縮空気を封入し空気室上に定盤を介して機器等を支承するよう にして使用される。使用時、定盤の高さの変動に応じて高さ調整弁により空気室 内の空気を給排し定盤の高さを常時一定に維持している。 Conventionally, an air spring body with one air chamber is composed of a hollow rubber body whose bottom end opening surface is hermetically closed by a bottom plate, and a height adjusting valve is connected to this air spring body via a pipe. There is an air spring device in which an air source is connected to the height adjusting valve. In this air spring device, an air spring body and a height adjustment valve are arranged in parallel, compressed air is enclosed in the air chamber of the air spring body, and equipment etc. is supported on the air chamber via a surface plate. used. During use, the height of the surface plate is adjusted by the height adjustment valve to supply and exhaust air in the air chamber to maintain the height of the surface plate constant at all times.

しかしながら、このような従来の空気ばね装置においては、機器等の荷重を 支持した状態において何等かの原因により空気室内の空気が抜けた場合は、中空 ゴム体の側部がゴムであることから大きくたわみ、併設されている高さ調整弁に 機器等の大荷重が移行して同高さ調整弁を損傷させてしまうことがある。これを 防止するため中空ゴム体の一定以上の上下振幅を押さえる振幅制御台を空気ばね 本体および高さ調整弁と共に併設することが行われているが、設置スペースの小 さい所では不向きである。 However, in such a conventional air spring device, when the air in the air chamber escapes for some reason while supporting the load of the equipment, etc. Deflection may cause a large load of equipment or the like to be transferred to the side-by-side height adjustment valve and damage the same height adjustment valve. In order to prevent this, an amplitude control table that suppresses the vertical amplitude above a certain level of the hollow rubber body is installed together with the air spring body and the height adjustment valve, but this is not suitable in places where the installation space is small.
【０００４】 また一つの空気室を備えた空気ばね装置により三次元測定器のような高速で動 く精密機器を支持した場合は、高さ調整弁より排出される圧縮空気が前記空気室 内に送り込まれてハンチングが発生し易いという難点がある。Further, when a precision instrument such as a three-dimensional measuring instrument that moves at high speed is supported by an air spring device having one air chamber, compressed air discharged from the height adjustment valve enters the air chamber. There is a drawback that hunting is likely to occur after being sent.
【０００５】 本考案は、このような従来の難点を解消すべくなされたもので、設置スペース が小さくハンチングが起こり難い空気ばね装置を提供することを目的とする。The present invention has been made in order to solve such a conventional problem, and an object thereof is to provide an air spring device having a small installation space and in which hunting hardly occurs.

本考案の空気ばね装置は、下端が開口した中空ゴム体とこの中空ゴム体の下 端開口面を気密に閉塞した底板とにより空気室を形成してなる空気ばね本体と、 一方の配管を介して前記空気ばね本体に連結されかつ他方の配管を介して空気源 に連結された高さ調整弁とを備えた空気ばね装置において、前記空気ばね本体の 空気室内に、前記ゴム状弾性体の一定以上の上下振幅を押さえる振幅制御台を配 設し、前記空気ばね本体と前記高さ調整弁との間の配管に、前記空気ばね本体内 の空気室より小さな容積の空気タンクを設けたことを特徴とするものである。 The air spring device of the present invention comprises an air spring body having an air chamber formed by a hollow rubber body having an open lower end and a bottom plate which hermetically closes the lower end opening surface of the hollow rubber body, and one of the pipes. A height adjusting valve connected to the air spring body and connected to an air source via the other pipe, a constant amount of the rubber-like elastic body is provided in the air chamber of the air spring body. An amplitude control table for suppressing the above vertical amplitude is provided, and an air tank having a smaller volume than the air chamber in the air spring body is provided in the pipe between the air spring body and the height adjusting valve. It is a feature.

本考案においては、振幅制御台により中空ゴム体の一定以上の振幅を押さえ 、空気ばね本体内の空気室より小さな容積の空気タンクにより空気ばね本体内で のハンチングの発生を防止し搭載機器の高速移動による初期変位を低減する。 In the present invention, the amplitude control block suppresses the amplitude of the hollow rubber body above a certain level, and the air tank having a smaller volume than the air chamber in the air spring body prevents the occurrence of hunting in the air spring body, thereby increasing the speed of the mounted equipment. The initial displacement due to movement is reduced.
【０００８】[0008]
以下、本考案の空気ばね装置を図に示した実施例に従い説明する。 図１は本考案の一実施例を示す概略図である。図１において空気ばね本体１０ は、下端が開口した中空円筒形の中空ゴム体１０ａとこの中空ゴム体の下端開口 面を気密に閉塞した底板１０ｂとにより一つの空気室１１が形成されている。 空気ばね本体１０の内部に、中空ゴム体１０ａの一定以上の上下振幅を押さえ る振幅制御台１２が配設されている。振幅制御台１２は底板１０ｂに立設された 脚部１３により支承されている。 中空ゴム体１０ａの側面には通気路１４が設けられ、この通気路１４に配管１ ５ａ、１５ｂ、１５ｃを介してそれぞれ空気タンク１６、高さ調整弁１７および 空気源１８が連結されている。空気タンク１６の容積は空気ばね本体の空気室１ １の容積より小さくされている。高さ調整弁１７は通常使用されている周知構造 のものであり、中空ゴム体１０ａ上に載置された定盤１９の底面に常時当接して おり、定盤１９の高さに応じて空気ばね本体１０に対する適当な空気の給排を行 うものである。空気タンク１６の両側の配管１５ａ、１５ｂにオリフィス２０ａ 、２０ｂが設けられている。 The air spring device of the present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 is a schematic view showing an embodiment of the present invention. In FIG. 1, the air spring main body 10 has one air chamber 11 formed by a hollow cylindrical hollow rubber body 10a having an open lower end and a bottom plate 10b that hermetically closes the open end of the lower end of the hollow rubber body. Inside the air spring body 10, an amplitude control table 12 for suppressing the vertical amplitude above a certain level of the hollow rubber body 10a is arranged. The amplitude control table 12 is supported by legs 13 standing on the bottom plate 10b. An air passage 14 is provided on the side surface of the hollow rubber body 10a, and an air tank 16, a height adjusting valve 17, and an air source 18 are connected to the air passage 14 via pipes 15a, 15b, 15c, respectively. The volume of the air tank 16 is smaller than the volume of the air chamber 11 of the air spring body. The height adjusting valve 17 has a commonly used well-known structure and is always in contact with the bottom surface of the surface plate 19 placed on the hollow rubber body 10a. The air is appropriately supplied to and discharged from the spring body 10. Orifices 20a, 20b are provided in the pipes 15a, 15b on both sides of the air tank 16.
【０００９】 本考案の空気ばね装置は上記のように構成され、空気ばね本体の空気室１１内 に圧縮空気を封入し定盤１９上に機器等を支承するようにして使用される。使用 時、定盤１９の高さの変動に応じて作動する高さ調整弁１７により空気室１１内 の空気を給排し定盤１９の高さを常時一定に維持している。空気室１１と高さ調 整弁１７との間を流通する空気は、比較的容積の小さい空気タンク１６および配 管１５ａ、１５ｂに設けられたオリフィス２０ａ、２０ｂを通過することにより ダンピングされる。このためハンチングの発生が防止されて定盤１９上に搭載さ れた機器等の高速移動による初期変位を半減する作用をする。また中空ゴム体１ ０ａが一定以上に上下振幅したときは、空気ばね本体１０の内部に設けられた振 幅制御台１２に当接して振幅が押えられる。The air spring device of the present invention is constructed as described above, and is used by enclosing compressed air in the air chamber 11 of the air spring main body and supporting equipment or the like on the surface plate 19. At the time of use, the height adjusting valve 17 that operates according to the height variation of the surface plate 19 supplies and exhausts the air in the air chamber 11 to constantly maintain the height of the surface plate 19 constant. The air flowing between the air chamber 11 and the height adjustment valve 17 is damped by passing through the air tank 16 having a relatively small volume and the orifices 20a and 20b provided in the pipes 15a and 15b. Therefore, the occurrence of hunting is prevented and the initial displacement due to the high speed movement of the equipment mounted on the surface plate 19 is halved. Further, when the hollow rubber body 10a oscillates above and below a certain level, it abuts on the amplitude control base 12 provided inside the air spring body 10 and the amplitude is suppressed.

以上説明したように本考案によれば、空気ばね本体の空気室内に、中空ゴム体 の一定以上の上下振幅を押さえる振幅制御台を配設したことにより、設置スペー スを縮小可能でありかつ空気ばね本体の一定以上の振幅を押さえることができる 。また空気ばね本体と高さ調整弁との間の配管に、空気ばね本体内の空気室より 小さな容積の空気タンクを設けたことにより、定盤上の機器の高速移動時におけ る初期変位を大幅に低減しうる。 As described above, according to the present invention, the installation space can be reduced and the installation space can be reduced by disposing the amplitude control table for suppressing the vertical amplitude of the hollow rubber body above a certain level in the air chamber of the air spring body. Amplitude above a certain level of the spring body can be suppressed. In addition, by installing an air tank with a smaller volume than the air chamber inside the air spring body in the pipe between the air spring body and the height adjustment valve, the initial displacement during high-speed movement of equipment on the surface plate can be greatly reduced. Can be reduced to
