Description

本発明は、温度、湿度等の雰囲気的環境試験を行う環境試験装置に用いられる環境試験用治具に関する。 The present invention relates to an environmental test jig used in an environmental test apparatus that performs an atmospheric environmental test such as temperature and humidity.

従来、電気・電子分野などの比較的小型な部品等から航空・宇宙分野などの比較的大型の製品等について、様々な振動条件の下で振動試験を行わせることにより、部品や製品の耐震性や耐久性を評価する装置として、加振機が知られている（例えば、特許文献１）。かかる加振機としては、温度、湿度等を調整した雰囲気的環境試験を行うための恒温槽と、振動等の物理的環境試験を行うための加振機とを備え、恒温槽で再現した雰囲気的環境と加振機で再現した物理的環境とを組み合わせて各種複合環境を再現して試験する複合環境加振機が知られている。 Conventionally, the vibration resistance of parts and products is made by conducting vibration tests under various vibration conditions for relatively small parts such as electrical and electronic fields to relatively large products such as aerospace and space. As a device for evaluating the durability, a vibrator is known (for example, Patent Document 1). As such a shaker, a thermostatic chamber for performing an atmospheric environmental test with adjusted temperature, humidity, etc., and a shaker for performing a physical environmental test such as vibration, an atmosphere reproduced in a thermostatic bath A complex environment shaker that reproduces and tests various complex environments by combining a dynamic environment and a physical environment reproduced by a shaker is known.

ところで、この複合環境加振機において、恒温槽内に設置された供試体を移動させたり、随時操作が必要な場合がある。
そこで、特許文献１記載の複合環境加振機は、恒温槽の開口部にシールした状態で恒温槽内に挿入される耐熱性のシリコンゴム手袋を備え、ユーザがそのシリコンゴム製の手袋を恒温槽内で着用することにより、試験中に供試体を移動させたり、操作することができるようになっている。
特開２００３−１９４６６４号公報 By the way, in this complex environment vibration exciter, a specimen installed in a thermostatic chamber may be moved or an operation may be necessary at any time.
Therefore, the composite environmental vibrator described in Patent Document 1 includes a heat-resistant silicone rubber glove that is inserted into the thermostatic chamber in a state of being sealed in the opening of the thermostatic bath, and the user can use the silicone rubber glove in the thermostatic chamber. By wearing it in the tank, the specimen can be moved and operated during the test.
JP 2003-194664 A

しかしながら、上記構成の複合環境加振機を用いる環境試験において、供試体の移動或いは操作を行う場合には、ユーザが試験中に恒温槽内に両手を挿入することとなるので、供試体の操作を長時間行う場合、高温試験時においては熱さに耐えることができず、また低温試験時においては凍傷になるおそれがある。また、恒温槽内に挿入されるシリコンゴム製の手袋も耐熱温度に限界があるため、高温環境下或いは低温環境下において供試体の操作を長時間行うことは困難であるという問題点があった。 However, when the specimen is moved or operated in an environmental test using the combined environmental vibrator with the above configuration, the user inserts both hands into the thermostatic chamber during the test. If the test is carried out for a long time, it cannot withstand heat during the high temperature test, and may cause frostbite during the low temperature test. In addition, the silicon rubber gloves inserted in the thermostatic chamber have a limit in heat-resistant temperature, so that it is difficult to operate the specimen for a long time in a high temperature environment or a low temperature environment. .

そこで、本発明の課題は、恒温槽内の雰囲気的環境に影響を受けることなく、ユーザが供試体の操作を長時間行うことができる環境試験用治具を提供することである。 Accordingly, an object of the present invention is to provide an environmental test jig that allows a user to operate a specimen for a long time without being affected by the atmospheric environment in the thermostat.

請求項１記載の発明によれば、開口部に挿通され、箱体内の供試体を操作するための棒状部材と、棒状部材を弾性支持し、棒状部材の先端部を供試体に対して直交３軸方向に相対的に移動自在とするとともに、箱体内の気密を保持する気密保持手段とを備えるので、箱体内の気密が保持された状態で、ユーザが箱体の外部から棒状部材を操作することによって供試体の移動或いは操作を行うことができる。従って、箱体内の雰囲気的環境に影響を受けることなく、ユーザが供試体の操作を長時間行うことができる。
また、気密保持手段は、棒状部材に貫通されるシリンダと、棒状部材とシリンダとの間の気密を保持するシール部材と、内周端部がシリンダに気密固定されるとともに、外周端部が壁部に気密固定され、棒状部材の移動に応じて弾性変形するベロフラムとを備えるので、棒状部材の移動方向に応じてベロフラムが弾性変形しながら棒状部材を弾性支持する。したがって、棒状部材の先端部のより微妙な操作が可能となる。 According to the first aspect of the present invention, the rod-shaped member that is inserted through the opening and operates the specimen in the box, and elastically supports the rod-shaped member, and the tip of the rod-shaped member is orthogonal to the specimen. Since it is relatively movable in the axial direction and has an airtight holding means for holding the airtightness in the box, the user operates the rod-shaped member from the outside of the box while the airtightness in the box is held. Thus, the specimen can be moved or operated. Therefore, the user can operate the specimen for a long time without being affected by the atmospheric environment in the box.
The airtight holding means includes a cylinder penetrating the rod-shaped member, a seal member for retaining airtightness between the rod-shaped member and the cylinder, an inner peripheral end portion being hermetically fixed to the cylinder, and an outer peripheral end portion being a wall. And a bellowram that is hermetically fixed to the portion and elastically deforms in accordance with the movement of the rod-shaped member. Therefore, the bellophram elastically supports the rod-shaped member while being elastically deformed in accordance with the moving direction of the rod-shaped member. Therefore, a more delicate operation of the tip end portion of the rod-like member is possible.

請求項２記載の発明によれば、開口部に挿通され、箱体内の供試体を操作するための棒状部材と、棒状部材を弾性支持し、棒状部材の先端部を供試体に対して直交３軸方向に相対的に移動自在とするとともに、箱体内の気密を保持する気密保持手段とを備えるので、箱体内の気密が保持された状態で、ユーザが箱体の外部から棒状部材を操作することによって供試体の移動或いは操作を行うことができる。従って、箱体内の雰囲気的環境に影響を受けることなく、ユーザが供試体の操作を長時間行うことができる。
また、気密保持手段は、棒状部材を弾性支持する弾性支持部と、壁部に気密固定され、弾性支持部を支持する支持部とを備え、棒状部材と弾性支持部との間及び弾性支持部と支持部との間の気密を保持するので、棒状部材をより安定した状態で操作することができる。
さらに、弾性支持部は棒状部材に貫通されるシリンダと、棒状部材とシリンダとの間の気密を保持するシール部材と、内周端部がシリンダに気密固定されるとともに、外周端部が支持部に気密固定され、棒状部材の移動に応じて弾性変形するベロフラムとを備えるので、棒状部材の移動方向に応じてベロフラムが弾性変形しながら棒状部材を弾性支持する。したがって、棒状部材の先端部のより微妙な操作が可能となる。 According to the second aspect of the present invention , the rod-shaped member that is inserted through the opening and operates the specimen within the box and elastically supports the rod-shaped member, and the tip of the rod-shaped member is orthogonal to the specimen. Since it is relatively movable in the axial direction and has an airtight holding means for holding the airtightness in the box, the user operates the rod-shaped member from the outside of the box while the airtightness in the box is held. Thus, the specimen can be moved or operated. Therefore, the user can operate the specimen for a long time without being affected by the atmospheric environment in the box.
The airtight holding means includes an elastic support portion that elastically supports the rod-like member, and a support portion that is airtightly fixed to the wall portion and supports the elastic support portion, and between the rod-like member and the elastic support portion and the elastic support portion. Since the airtightness between the support member and the support portion is maintained, the rod-like member can be operated in a more stable state.
Furthermore, the elastic support portion includes a cylinder penetrating the rod-shaped member, a seal member that maintains airtightness between the rod-shaped member and the cylinder, an inner peripheral end portion is hermetically fixed to the cylinder, and an outer peripheral end portion is the support portion. And a bellowram that is elastically deformed according to the movement of the rod-shaped member, and the bellophram elastically supports the rod-shaped member while being elastically deformed according to the moving direction of the rod-shaped member. Therefore, a more delicate operation of the tip end portion of the rod-like member is possible.

請求項３記載の発明によれば、請求項１又は２記載の発明と同様の効果が得られるのは無論のこと、特に、シリンダは、棒状部材を貫通させる貫通孔を有する本体部と、本体部の内周面の一部が切り欠かれて形成され、シール部材を収容する切欠溝と、切欠溝に収容されたシール部材を押え付けて本体部に固定されるシール部材押え板とを備えるので、棒状部材を箱体外に引っ張った場合でもシール部材が切欠溝から外れることがない。 According to the invention described in claim 3, it is needless to say that the same effect as that of the invention described in claim 1 or 2 can be obtained. In particular, the cylinder has a main body portion having a through-hole through which a rod-shaped member passes, A part of the inner peripheral surface of the part is formed by notching, and includes a notch groove that accommodates the seal member, and a seal member presser plate that presses the seal member accommodated in the notch groove and is fixed to the main body part. Therefore, even when the rod-shaped member is pulled out of the box, the seal member does not come off from the notch groove.

請求項４記載の発明によれば、請求項１〜３の何れか一項に記載の発明と同様の効果が得られるのは無論のこと、特に、箱体の開口部に挿入されるとともに、棒状部材の先端部を移動自在に内包するスリーブ部材を備えるので、箱体内の気密性を格段に向上させることができるとともに、棒状部材を安定して操作できる。 According to the invention of claim 4, it is natural that the same effect as that of any one of claims 1 to 3 can be obtained, in particular, inserted into the opening of the box, Since the sleeve member that includes the tip of the rod-shaped member in a movable manner is provided, the airtightness in the box can be remarkably improved and the rod-shaped member can be stably operated.

以下、図を用いて本発明に係る環境試験用治具の実施の形態について詳細に説明する。
図１は、本発明に係る環境試験用治具を適用した複合環境加振機の断面側面図、図２は、図１の環境試験用治具の要部を拡大して示した断面側面図、図３は、図２の環境試験用治具の棒状部材を恒温槽内に押し込んだ状態を示す断面側面図、図４は、図２の環境試験用治具の棒状部材を恒温槽外に引っ張った状態を示す断面側面図である。
環境試験装置としての複合環境加振機１は、例えば、図１に示すように、箱体としての恒温槽２と、恒温槽２内に設けられる加振部３等を備え、恒温槽２の壁部４には環境試験用治具１０が着脱自在に取り付けられている。 Hereinafter, embodiments of an environmental test jig according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a cross-sectional side view of a composite environmental shaker to which an environmental test jig according to the present invention is applied, and FIG. 2 is an enlarged cross-sectional side view showing a main part of the environmental test jig of FIG. 3 is a cross-sectional side view showing a state in which the rod-shaped member of the environmental test jig of FIG. 2 is pushed into the thermostatic chamber. FIG. 4 is a diagram illustrating the rod-shaped member of the environmental test jig of FIG. It is a cross-sectional side view which shows the state pulled.
For example, as shown in FIG. 1, a combined environmental shaker 1 as an environmental test apparatus includes a thermostatic chamber 2 as a box, a vibration unit 3 provided in the thermostatic chamber 2, and the like. An environmental test jig 10 is detachably attached to the wall 4.

恒温槽２は、内部空間を有する箱状体であって、該恒温槽２の壁部４には円形にくり貫かれた開口部５が形成されている。また、開口部５の上方には窓部６が設けられており、恒温槽２の外部から恒温槽２の内部を観察できるようになっている。恒温槽２内の温度及び湿度は所定の値に調整が可能である。
加振部３は、恒温槽２の下部に設けられており、供試体Ｓが載置され、供試体Ｓに振動を与える加振台３ａと、加振台３ａを振動させる加振力を発生させる振動発生機構部３ｂ等を備えている。 The thermostat 2 is a box-shaped body having an internal space, and an opening 5 is formed in the wall 4 of the thermostat 2 so as to penetrate in a circular shape. A window 6 is provided above the opening 5 so that the inside of the thermostat 2 can be observed from the outside of the thermostat 2. The temperature and humidity in the thermostat 2 can be adjusted to predetermined values.
The vibration part 3 is provided in the lower part of the thermostat 2, and the specimen S is placed thereon, and the vibration table 3a that vibrates the specimen S and the vibration force that vibrates the vibration table 3a are generated. The vibration generating mechanism 3b and the like are provided.

環境試験用治具１０は、図２に示すように、供試体Ｓを操作するための棒状部材１１と、棒状部材１１を弾性支持するとともに、恒温槽２内の気密を保持する気密保持手段としての弾性支持部２０及び支持部３０を備えている。 As shown in FIG. 2, the environmental test jig 10 is a rod-like member 11 for operating the specimen S, and an airtight holding means that elastically supports the rod-like member 11 and holds the airtightness in the thermostat 2. The elastic support part 20 and the support part 30 are provided.

棒状部材１１は、恒温槽２の開口部５に挿入されるスポンジゴム１２を介して挿通されており、一端部に供試体Ｓを操作するための先端部１１１が、他端部にはユーザが掴む掴み部１１２が設けられている。即ち、先端部１１１が恒温槽２内に位置するとともに、掴み部１１２が恒温槽２外に位置するようになっており、恒温槽２内の供試体Ｓを先端部１１１で操作できるようになっている。また、環境試験用治具１０の取付け時には棒状部材１１が恒温槽２の壁部４に直交するように構成されている。 The rod-shaped member 11 is inserted through a sponge rubber 12 inserted into the opening 5 of the thermostatic chamber 2, and a distal end portion 111 for operating the specimen S is provided at one end portion, and a user is provided at the other end portion. A grip portion 112 for gripping is provided. That is, the tip 111 is positioned inside the thermostat 2 and the grip 112 is positioned outside the thermostat 2 so that the specimen S in the thermostat 2 can be operated by the tip 111. ing. Further, the rod-shaped member 11 is configured to be orthogonal to the wall portion 4 of the thermostatic chamber 2 when the environmental test jig 10 is attached.

棒状部材１１は、供試体Ｓの移動或いは操作を行う部材であるため、例えば、アルミニウムにより構成され、中空部１１３を有している。また、棒状部材１１の掴み部１１２は、試験中の供試体Ｓの操作に伴う熱伝導を防ぐための断熱部材により構成されている。なお、棒状部材１１の先端部１１１は、供試体Ｓを操作し易い形状に加工されているものが好ましい。 Since the rod-shaped member 11 is a member that moves or operates the specimen S, for example, it is made of aluminum and has a hollow portion 113. Moreover, the grip part 112 of the rod-shaped member 11 is comprised with the heat insulation member for preventing the heat conduction accompanying operation of the test body S under test. Note that the tip 111 of the rod-shaped member 11 is preferably processed into a shape that allows the specimen S to be easily operated.

スポンジゴム１２は、恒温槽２の開口部５に挿入されるとともに、棒状部材１１の先端部１１１を移動自在に内包するスリーブ部材として機能する。このスポンジゴム１２は、断熱性及び気密性を有するので、恒温槽２内の気密をより確実に保持できるようになっている。 The sponge rubber 12 functions as a sleeve member that is inserted into the opening 5 of the thermostatic chamber 2 and that includes the tip 111 of the rod-shaped member 11 so as to be movable. Since the sponge rubber 12 has heat insulating properties and airtightness, the airtightness in the thermostat 2 can be more reliably maintained.

弾性支持部２０は、恒温槽２外に設けられており、棒状部材１１に貫通されるシリンダ２１と、棒状部材１１とシリンダ２１との間の気密を保持するシール部材としてのメインパッキン２２と、内周端部がシリンダ２１に気密固定されるとともに、外周端部が支持部３０に気密固定されているベロフラム２３等を備えている。 The elastic support portion 20 is provided outside the thermostat 2, and includes a cylinder 21 that penetrates the rod-shaped member 11, a main packing 22 as a seal member that maintains airtightness between the rod-shaped member 11 and the cylinder 21, The inner peripheral end portion is hermetically fixed to the cylinder 21, and the outer peripheral end portion is airtightly fixed to the support portion 30.

シリンダ２１は、略円筒形状を成しており、棒状部材１１を貫通させる貫通孔２１１ａを有する本体部２１１と、本体部２１１の内周面の一部が切り欠かれて形成され、メインパッキン２２を収容する切欠溝２１２とから構成されている。シリンダ２１の本体部２１１には、切欠溝２１２に収容されるメインパッキン２２を押え付けるシール部材押え板としてのパッキン押え板２４が固定されている。 The cylinder 21 has a substantially cylindrical shape, and is formed by cutting out a main body portion 211 having a through hole 211 a through which the rod-shaped member 11 passes, and a part of the inner peripheral surface of the main body portion 211. It is comprised from the notch groove 212 which accommodates. A packing presser plate 24 as a seal member presser plate for pressing the main packing 22 accommodated in the notch groove 212 is fixed to the main body 211 of the cylinder 21.

メインパッキン２２は、例えば、シリコンゴムにより構成されており、棒状部材１１の径より僅かに小さい径を有している。即ち、メインパッキン２２は、棒状部材１１に挿入されることにより、半径方向外方に弾性変形して、棒状部材１１の外周面に密着するようになっている。 The main packing 22 is made of, for example, silicon rubber and has a diameter slightly smaller than the diameter of the rod-shaped member 11. That is, the main packing 22 is elastically deformed outward in the radial direction by being inserted into the rod-shaped member 11, and comes into close contact with the outer peripheral surface of the rod-shaped member 11.

また、メインパッキン２２は、棒状部材１１の外周面に密着した状態で、シリンダ２１の切欠溝２１２に収容されている。この切欠溝２１２の径は、メインパッキン２２の径より僅かに小さいので、メインパッキン２２は切欠溝２１２に押え付けられることとなり、シリンダ２１とメインパッキン２２との間の気密を保持できるようになっている。 The main packing 22 is accommodated in the notch groove 212 of the cylinder 21 in a state of being in close contact with the outer peripheral surface of the rod-shaped member 11. Since the diameter of the notch groove 212 is slightly smaller than the diameter of the main packing 22, the main packing 22 is pressed against the notch groove 212, and the airtightness between the cylinder 21 and the main packing 22 can be maintained. ing.

パッキン押え板２４は、本体部２１１の貫通孔２１１ａとほぼ同径の孔部を有する円盤状の板である。このパッキン押え板２４は、シリンダ２１の切欠溝２１２に収容されているメインパッキン２２を押え付けて、本体部２１１にねじ固定されている。そして、棒状部材１１を恒温槽２外に引っ張ったときにメインパッキン２２が切欠溝２１２から外れないようになっている。即ち、シリンダ２１を手で固定しておいて、所定の力以上の力で棒状部材１１を押し込み動作或いは引っ張り動作を行うと、メインパッキン２２内を棒状部材１１がその動作方向へ摺動できるようになっている。 The packing retainer plate 24 is a disk-shaped plate having a hole portion having substantially the same diameter as the through hole 211 a of the main body portion 211. The packing pressing plate 24 presses the main packing 22 accommodated in the notch groove 212 of the cylinder 21 and is screwed to the main body 211. The main packing 22 is prevented from being removed from the notch groove 212 when the rod-shaped member 11 is pulled out of the thermostat 2. That is, when the cylinder 21 is fixed by hand and the rod-shaped member 11 is pushed or pulled with a force greater than a predetermined force, the rod-shaped member 11 can slide in the operation direction in the main packing 22. It has become.

ベロフラム２３は、例えば、シリコンゴムにより構成されている。このベロフラム２３は、シリンダ２１の本体部２１１に気密固定される内周端部としての第一固定部２３１と、第一固定部２３１の周縁部から棒状部材１１の掴み部１１２側に対して折り返して形成される折り返し部２３２と、折り返し部２３２から外方に延在して、支持部３０に気密固定される外周端部としての第二固定部２３３とから一体的に構成されている。
ベロフラム２３の第一固定部２３１とシリンダ２１の本体部２１１とは、棒状部材１１の径よりやや大きい径を有する円盤状のシリンダ押え板２５を介してねじ固定されている。シリコンゴムは、耐熱性及び耐冷性を有する弾性体であるため、ベロフラム２３の材質として好適である。 The bellophram 23 is made of, for example, silicon rubber. The bellophram 23 is folded back from the peripheral portion of the first fixing portion 231 to the grip portion 112 side of the rod-like member 11 as an inner peripheral end portion hermetically fixed to the main body portion 211 of the cylinder 21. The folded portion 232 is formed integrally with a second fixed portion 233 that extends outward from the folded portion 232 and is hermetically fixed to the support portion 30.
The first fixing portion 231 of the bellophram 23 and the main body portion 211 of the cylinder 21 are fixed by screws via a disk-shaped cylinder pressing plate 25 having a diameter slightly larger than the diameter of the rod-shaped member 11. Since silicon rubber is an elastic body having heat resistance and cold resistance, it is suitable as a material for the belofram 23.

このベロフラム２３は、例えば図３、図４に示すように、第一固定部２３１が移動するにつれて折り返し部２３２の長さが変化して、棒状部材１１がストローク移動できるようになっている。
即ち、棒状部材１１を所定の方向に移動させると、その移動に応じてベロフラム２３が弾性変形しながら棒状部材１１を弾性支持することにより、棒状部材１１の先端部１１１によって供試体Ｓの移動或いは操作を行うことができるようになっている。 For example, as shown in FIGS. 3 and 4, the bellowram 23 is configured such that the length of the folded portion 232 changes as the first fixing portion 231 moves so that the rod-shaped member 11 can move by a stroke.
That is, when the rod-shaped member 11 is moved in a predetermined direction, the bellowram 23 is elastically deformed in accordance with the movement of the rod-shaped member 11 and elastically supports the rod-shaped member 11. The operation can be performed.

支持部３０は、弾性支持部２０を支持するとともに、恒温槽２の壁部４に気密固定されている。この支持部３０は、略円盤状に形成され、中央部に孔部を有しているベロフラム支持部材３１と、ベロフラム支持部材３１の周縁部に設けられているスペーサ３２とから構成される。
具体的には、ベロフラム支持部材３１の一方の面の孔部近傍に、ベロフラム２３の第二固定部２３３が気密固定されている。この気密固定は、ベロフラム支持部材３１の径とほぼ同じ径を有する円盤状のベロフラム押え板２６によりベロフラム２３の第二固定部２３３を押え、ねじ固定することによりなされる。また、ベロフラム支持部材３１の他方の面の周縁部には、環状のスペーサ３２が気密固定されている。 The support portion 30 supports the elastic support portion 20 and is airtightly fixed to the wall portion 4 of the thermostatic chamber 2. The support portion 30 is formed in a substantially disc shape, and includes a bellophram support member 31 having a hole in the center portion, and a spacer 32 provided on the peripheral portion of the bellophram support member 31.
Specifically, the second fixing portion 233 of the bellophram 23 is airtightly fixed in the vicinity of the hole on one surface of the bellophram support member 31. This hermetic fixing is performed by pressing the second fixing portion 233 of the bellophram 23 with a disk-shaped bellophram pressing plate 26 having substantially the same diameter as that of the bellophram supporting member 31 and screw fixing. An annular spacer 32 is airtightly fixed to the peripheral edge portion of the other surface of the bellophram support member 31.

スペーサ３２は、恒温槽２の開口部５の径とほぼ同じ大きさの径を有しており、サブパッキン３３でシールされてベロフラム支持部材３１に気密固定されている。また、スペーサ３２の壁部４側の面も、同様にサブパッキン３３でシールされており、恒温槽２内の気密を保持できるようになっている。このスペーサ３２を設けることによって、恒温槽２の壁部４にスポンジゴム１２を挿入した状態においても、棒状部材１１のストローク移動を確保できるようになっている。 The spacer 32 has a diameter substantially the same as the diameter of the opening 5 of the thermostatic chamber 2, is sealed by the sub-packing 33, and is airtightly fixed to the bellophram support member 31. Also, the wall 4 side surface of the spacer 32 is similarly sealed by the sub-packing 33 so that the airtightness in the thermostatic chamber 2 can be maintained. By providing the spacer 32, the stroke movement of the rod-shaped member 11 can be secured even when the sponge rubber 12 is inserted into the wall portion 4 of the thermostatic chamber 2.

サブパッキン３３は、例えば、シリコンゴムにより構成され、スペーサ３２の径とほぼ同じ大きさの径を有する環状のパッキンである。
そして、ベロフラム支持部材３１及びスペーサ３２を恒温槽２の壁部４とねじ固定することにより、支持部３０が恒温槽２の壁部４に気密固定されるようになっている。 The sub-packing 33 is an annular packing made of, for example, silicon rubber and having a diameter substantially the same as the diameter of the spacer 32.
The support 30 is hermetically fixed to the wall 4 of the thermostat 2 by screwing the belofram support member 31 and the spacer 32 to the wall 4 of the thermostat 2.

上記のように環境試験用治具１０を構成することにより、棒状部材１１と弾性支持部２０との間及び弾性支持部２０と支持部３０との間の気密が保持されることとなる。 By configuring the environmental test jig 10 as described above, the airtightness between the rod-shaped member 11 and the elastic support portion 20 and between the elastic support portion 20 and the support portion 30 is maintained.

次に、上記構成の環境試験用治具１０を取り付けた複合環境加振機１を用いて行う複合環境試験の一例について詳細に説明する。
先ず、環境試験用治具１０の棒状部材１１を、スポンジゴム１２に貫通させておく。次いで、複合環境加振機１の恒温槽２の壁部４に装着されている開口部５のカバー（図示省略）を取り外す。次いで、恒温槽２の壁部４の開口部５に、環境試験用治具１０を取り付ける。 Next, an example of a combined environmental test performed using the combined environmental shaker 1 to which the environmental test jig 10 having the above configuration is attached will be described in detail.
First, the rod-like member 11 of the environmental test jig 10 is passed through the sponge rubber 12. Next, the cover (not shown) of the opening 5 attached to the wall 4 of the thermostatic chamber 2 of the complex environment shaker 1 is removed. Next, an environmental test jig 10 is attached to the opening 5 of the wall 4 of the thermostat 2.

具体的には、先ず、棒状部材１１が貫通しているスポンジゴム１２を、開口部５に挿入させる。次いで、環境試験用治具１０のベロフラム支持部材３１及びスペーサ３２と、壁部４とをねじ止めする。スペーサ３２の両側にはサブパッキン３３がシールされているので、このねじ止めによってスペーサ３２と壁部４との間の気密は保持される。そして、恒温槽２内を所定の温度、湿度になるよう調節して、所定の雰囲気的環境に設定するとともに、振動発生機構部３ｂによる加振台３ａの振動の物理的環境試験を組み合わせて複合環境試験を行う。 Specifically, first, the sponge rubber 12 through which the rod-shaped member 11 passes is inserted into the opening 5. Next, the belofram support member 31 and the spacer 32 of the environmental test jig 10 and the wall portion 4 are screwed. Since the sub-packings 33 are sealed on both sides of the spacer 32, the airtightness between the spacer 32 and the wall portion 4 is maintained by this screwing. Then, the inside of the thermostatic chamber 2 is adjusted to a predetermined temperature and humidity so as to be set to a predetermined atmospheric environment, and combined with a physical environment test of vibration of the vibration table 3a by the vibration generating mechanism 3b. Conduct environmental tests.

ユーザは、複合環境加振機１によって試験を実施する際に、例えば、供試体Ｓを移動させたり、何らかの操作を加える必要がある場合、加振部３による加振を停止させてから、環境試験用治具１０によって、供試体Ｓの移動或いは操作を行う。
このとき、ユーザは、棒状部材１１の掴み部１１２を掴み、恒温槽２の窓部６越しに恒温槽２内の供試体Ｓを確認しながら、棒状部材１１の先端部１１１を手操作で所望の方向へ移動させることにより、供試体Ｓの移動或いは操作を行う。 When the user performs a test using the composite environment shaker 1, for example, when the specimen S needs to be moved or some operation needs to be performed, The specimen S is moved or operated by the test jig 10.
At this time, the user manually grasps the tip 111 of the rod-shaped member 11 while grasping the grip portion 112 of the rod-shaped member 11 and confirming the specimen S in the thermostatic chamber 2 through the window portion 6 of the thermostatic chamber 2. The specimen S is moved or operated by moving in the direction of.

例えば、棒状部材１１を恒温槽２内に押し込むと、図３に示すように、押し込み動作に伴って、棒状部材１１を支持しているシリンダ２１がその押し込み方向へ移動するので、シリンダ２１が固定されているベロフラム２３の第一固定部２３１が押し込み方向へ移動する。即ち、折り返し部２３２の長さは短くなる。また、スポンジゴム１２も棒状部材１１の押し込み動作に応じて弾性変形する。 For example, when the rod-shaped member 11 is pushed into the thermostat 2, as shown in FIG. 3, the cylinder 21 supporting the rod-shaped member 11 moves in the pushing direction along with the pushing operation, so that the cylinder 21 is fixed. The first fixing portion 231 of the bellophram 23 is moved in the pushing direction. That is, the length of the folded portion 232 is shortened. The sponge rubber 12 is also elastically deformed in response to the pushing operation of the rod-shaped member 11.

逆に、棒状部材１１を恒温槽２外に引っ張ると、図４に示すように、引っ張り動作に伴って、棒状部材１１を支持しているシリンダ２１がその引っ張り方向へ移動するので、シリンダ２１が固定されているベロフラム２３の第一固定部２３１が引っ張り方向へ移動する。即ち、折り返し部２３２の長さは長くなる。また、スポンジゴム１２も棒状部材１１の引っ張り動作に応じて弾性変形する。つまり、この棒状部材１１の押し込み及び引っ張り動作によって、ユーザから見て棒状部材１１の先端部１１１が供試体Ｓに対して前後方向に移動することとなる。 On the contrary, when the rod-shaped member 11 is pulled out of the thermostat 2, as shown in FIG. 4, the cylinder 21 supporting the rod-shaped member 11 moves in the pulling direction along with the pulling operation. The first fixing portion 231 of the fixed bellophram 23 moves in the pulling direction. That is, the length of the folded portion 232 becomes longer. The sponge rubber 12 is also elastically deformed according to the pulling operation of the rod-shaped member 11. That is, by pushing and pulling the bar-shaped member 11, the distal end portion 111 of the bar-shaped member 11 moves in the front-rear direction with respect to the specimen S as viewed from the user.

また、例えば図５に示すように、棒状部材１１を傾斜させて、先端部１１１を供試体Ｓのより下方に接触させて、供試体Ｓの移動或いは操作を行う。このとき、ベロフラム２３の折り返し部２３２及びスポンジゴム１２は、その傾斜動作に伴って弾性変形する。なお、逆に棒状部材１１の先端部１１１を供試体Ｓの上方に接触させることも無論可能である。つまり、棒状部材１１の傾斜動作によって、ユーザから見て棒状部材１１の先端部１１１が供試体Ｓに対して上下方向に移動することとなる。 For example, as shown in FIG. 5, the rod-shaped member 11 is inclined, and the tip 111 is brought into contact with the lower side of the specimen S, so that the specimen S is moved or operated. At this time, the folded portion 232 and the sponge rubber 12 of the belofram 23 are elastically deformed along with the tilting operation. On the contrary, it is of course possible to bring the tip 111 of the rod-shaped member 11 into contact with the upper side of the specimen S. That is, the tip portion 111 of the rod-shaped member 11 moves in the vertical direction with respect to the specimen S as viewed from the user by the tilting operation of the rod-shaped member 11.

また、棒状部材１１を恒温槽２の壁部４に直交する平面内を移動させて、棒状部材１１の先端部１１１を所望の位置に移動させて、供試体Ｓの移動或いは操作を行う。このとき、ベロフラム２３の第一固定部２３１及びスポンジゴム１２がその移動動作に伴って弾性変形する。つまり、棒状部材１１の移動動作によって、ユーザから見て棒状部材１１の先端部１１１が供試体Ｓに対して左右方向に移動することとなる。 Moreover, the specimen S is moved or operated by moving the rod-shaped member 11 in a plane orthogonal to the wall 4 of the thermostat 2 and moving the tip 111 of the rod-shaped member 11 to a desired position. At this time, the first fixing portion 231 and the sponge rubber 12 of the belofram 23 are elastically deformed along with the moving operation. That is, the movement of the rod-shaped member 11 causes the tip 111 of the rod-shaped member 11 to move in the left-right direction with respect to the specimen S as viewed from the user.

さらに、必要に応じて、上述した棒状部材１１の移動動作を組み合わせて、供試体Ｓの移動或いは操作を行う。
例えば、棒状部材１１を供試体Ｓに対して前後方向に移動させながら、上下方向に傾斜させることも可能である。また、棒状部材１１を供試体Ｓに対して上下方向に傾斜させながら、左右方向に移動させることも可能である。また、棒状部材１１を供試体Ｓに対して左右方向に移動させながら、前後方向に移動させることも可能である。 Furthermore, the specimen S is moved or operated in combination with the above-described movement of the rod-shaped member 11 as necessary.
For example, the bar-shaped member 11 can be tilted in the vertical direction while moving in the front-rear direction with respect to the specimen S. Further, it is possible to move the rod-shaped member 11 in the left-right direction while inclining the sample-shaped member 11 in the up-down direction. Further, the rod-shaped member 11 can be moved in the front-rear direction while moving in the left-right direction with respect to the specimen S.

このように、棒状部材１１の移動に応じて、棒状部材１１を弾性支持しているベロフラム２３が弾性変形するので、棒状部材１１の先端部１１１を供試体Ｓに対して、前後方向、左右方向、上下方向に移動させることが可能である。即ち、供試体Ｓに対して直交３軸方向に、相対的に移動可能であるといえる。 In this way, as the rod-shaped member 11 is elastically deformed, the bellophram 23 that elastically supports the rod-shaped member 11 is elastically deformed. It is possible to move in the vertical direction. That is, it can be said that it can move relative to the specimen S in the three orthogonal directions.

また、環境試験用治具１０を複合環境加振機１に取り付けた後、環境試験用治具１０の操作前における棒状部材１１の位置を変えたい場合には、環境試験用治具１０のシリンダ２１を手で動かないように固定しておいて、棒状部材１１を恒温槽２内に所定の力以上の力で押し込む或いは恒温槽２外に引っ張る操作をする。この押し込み或いは引っ張り動作によって、メインパッキン２２内を棒状部材１１がその動作方向に摺動する。そして、棒状部材１１を所望の位置まで摺動させたら、押し込み或いは引っ張り動作を止めて、図６に示すようにその摺動後の位置でメインパッキン２２を棒状部材１１に密着させる。 When the position of the rod-shaped member 11 before the operation of the environmental test jig 10 is to be changed after the environmental test jig 10 is attached to the composite environmental shaker 1, the cylinder of the environmental test jig 10 is used. 21 is fixed so as not to move by hand, and the rod-like member 11 is pushed into the thermostat 2 with a force greater than a predetermined force or pulled out of the thermostat 2. By this pushing or pulling operation, the rod-shaped member 11 slides in the operation direction in the main packing 22. When the rod-shaped member 11 is slid to a desired position, the pushing or pulling operation is stopped, and the main packing 22 is brought into close contact with the rod-shaped member 11 at the position after the sliding as shown in FIG.

棒状部材１１の先端部１１１で供試体Ｓの移動或いは操作を行った後に、再度供試体Ｓに対して加振部３によって加振を付与し、複合環境試験を続行する。
複合環境試験終了後は、環境試験用治具１０の支持部３０と、恒温槽２の壁部４とのねじ固定を解除し、次いで棒状部材１１が貫通しているスポンジゴム１２を恒温槽２の開口部５から取り外す。そして、開口部５にカバーを装着して、次回の環境試験に備える。 After moving or operating the specimen S at the tip 111 of the rod-shaped member 11, the vibration is applied to the specimen S again by the vibrator 3, and the combined environmental test is continued.
After the completion of the combined environmental test, the screw fixing between the support portion 30 of the environmental test jig 10 and the wall portion 4 of the thermostatic chamber 2 is released, and then the sponge rubber 12 through which the rod-shaped member 11 penetrates the thermostatic chamber 2. Remove from the opening 5. Then, a cover is attached to the opening 5 to prepare for the next environmental test.

以上説明した環境試験用治具１０によれば、恒温槽２外に設けられる弾性支持部２０と、弾性支持部２０を支持するとともに、恒温槽２の壁部４に気密固定される支持部３０とを備え、弾性支持部２０は、棒状部材１１に貫通されるシリンダ２１と、棒状部材１１とシリンダ２１との間の気密を保持するメインパッキン２２と、内周端部がシリンダ２１の本体部２１１に気密固定されるとともに、外周端部がベロフラム支持部材３１に気密固定され、棒状部材１１の移動に応じて弾性変形するベロフラム２３とを備えているので、複合環境加振機１の恒温槽２内の気密を保持しつつ、ユーザが棒状部材１１を操作して、供試体Ｓを容易に移動させたり操作させたりできる。従って、恒温槽２内の雰囲気的環境に影響を受けることなく、ユーザが恒温槽２内の供試体Ｓの操作を長時間行うことができる。 According to the environmental test jig 10 described above, the elastic support 20 provided outside the thermostat 2 and the support 30 that supports the elastic support 20 and is airtightly fixed to the wall 4 of the thermostat 2. The elastic support portion 20 includes a cylinder 21 penetrating the rod-shaped member 11, a main packing 22 that maintains airtightness between the rod-shaped member 11 and the cylinder 21, and an inner peripheral end portion of the main body portion of the cylinder 21. Since the outer peripheral end is hermetically fixed to the bellophram support member 31 and is elastically deformed in accordance with the movement of the rod-shaped member 11, the thermostatic chamber of the combined environmental vibration exciter 1 is provided. The user can operate the rod-shaped member 11 and easily move or operate the specimen S while maintaining the hermeticity in 2. Therefore, the user can operate the specimen S in the thermostat 2 for a long time without being affected by the atmospheric environment in the thermostat 2.

また、棒状部材１１の移動方向に応じてベロフラム２３が弾性変形しながら棒状部材１１を弾性支持するので、棒状部材１１の先端部１１１のより微妙な操作が可能となる。
また、弾性支持部２０は、壁部４に気密固定されている支持部３０に支持されているので、棒状部材１１をより安定して操作することができる。 Further, since the belofram 23 elastically deforms and elastically supports the rod-shaped member 11 in accordance with the moving direction of the rod-shaped member 11, a more delicate operation of the distal end portion 111 of the rod-shaped member 11 is possible.
Moreover, since the elastic support part 20 is supported by the support part 30 airtightly fixed to the wall part 4, the rod-shaped member 11 can be operated more stably.

また、シリンダ２１は、棒状部材１１を貫通させるための貫通孔２１１ａを有する本体部２１１と、本体部２１１の内周面の一部が切り欠かれて形成され、メインパッキン２２を収容する切欠溝２１２を備えており、切欠溝２１２に収容されたメインパッキン２２はパッキン押え板２４により押し付けられてねじ固定されているので、棒状部材１１を恒温槽２外に引っ張った場合でもメインパッキン２２が切欠溝２１２から外れることがない。
また、恒温槽２の開口部５には、スポンジゴム１２が挿入されているので、棒状部材１１を安定した状態で操作できるとともに、恒温槽２内の気密性を格段に向上させることができる。 The cylinder 21 has a main body portion 211 having a through-hole 211 a for allowing the rod-like member 11 to pass therethrough, and a cutout groove that accommodates the main packing 22 by forming a part of the inner peripheral surface of the main body portion 211. 212. Since the main packing 22 accommodated in the notch groove 212 is pressed and fixed by the packing retainer plate 24, the main packing 22 is notched even when the rod-shaped member 11 is pulled out of the thermostat 2. It does not come off from the groove 212.
In addition, since the sponge rubber 12 is inserted into the opening 5 of the thermostatic chamber 2, the rod-shaped member 11 can be operated in a stable state, and the airtightness in the thermostatic chamber 2 can be significantly improved.

（変形例）
図７は、図１の環境試験用治具１０の変形例の要部を拡大して示した断面側面図である。図７に示す環境試験用治具１００は、複合環境加振機１の恒温槽２の壁部４に、棒状部材１１を弾性支持するベロフラム４０が気密固定されている。 (Modification)
FIG. 7 is an enlarged cross-sectional side view showing a main part of a modified example of the environmental test jig 10 of FIG. In an environmental test jig 100 shown in FIG. 7, a bellophram 40 that elastically supports the rod-shaped member 11 is airtightly fixed to the wall portion 4 of the thermostatic chamber 2 of the composite environmental shaker 1.

ベロフラム４０は、図２に示す環境試験用治具１０のベロフラム２３とほぼ同様の構成を成しており、シリンダ２１の本体部２１１に気密固定される内周端部としての第一固定部４０１と、第一固定部４０１の周縁部から棒状部材１１の掴み部１１２側に対して折り返して形成される折り返し部４０２と、折り返し部４０２から外方に延在して、壁部４に気密固定される外周端部としての第二固定部４０３とから一体的に構成されている。 The bellophram 40 has substantially the same configuration as the bellophram 23 of the environmental test jig 10 shown in FIG. 2, and a first fixing portion 401 as an inner peripheral end portion that is airtightly fixed to the main body portion 211 of the cylinder 21. A folded portion 402 formed by folding back from the peripheral portion of the first fixed portion 401 toward the grip portion 112 side of the rod-shaped member 11, and extending outward from the folded portion 402 to be hermetically fixed to the wall portion 4. It is comprised integrally from the 2nd fixing | fixed part 403 as an outer peripheral edge part.

具体的には、ベロフラム４０の第二固定部４０３の一端部から他端部までの長さが、壁部４の開口部５の径より大きく形成されており、その第二固定部４０３の端部がベロフラム押え板２６により壁部４に気密固定されている。即ち、ベロフラム４０を支持する支持部を設けることなく、ベロフラム４０を直接壁部４に気密固定している点で、環境試験用治具１０と異なっている。また、棒状部材１１のストローク移動を確保するため、壁部４の開口部５にスポンジゴム１２は挿入されていない。なお、環境試験用治具１０と同様の構成、動作については同一の符号を付し、詳細な説明を省略する。 Specifically, the length from the one end portion to the other end portion of the second fixing portion 403 of the bellophram 40 is formed to be larger than the diameter of the opening portion 5 of the wall portion 4, and the end of the second fixing portion 403 is formed. The portion is hermetically fixed to the wall portion 4 by a bellophram press plate 26. That is, it differs from the environmental test jig 10 in that the bellophram 40 is directly and airtightly fixed to the wall portion 4 without providing a support portion for supporting the bellophram 40. Further, in order to ensure the stroke movement of the rod-shaped member 11, the sponge rubber 12 is not inserted into the opening 5 of the wall 4. In addition, the same code | symbol is attached | subjected about the structure and operation | movement similar to the jig | tool 10 for environmental tests, and detailed description is abbreviate | omitted.

環境試験用治具１００は、例えば、棒状部材１１をユーザの前方向に移動させた場合は、ベロフラム４０の第一固定部４０１がその方向に移動し、恒温槽２の開口部５内をベロフラム４０の折り返し部４０２の内側が移動することとなる。即ち、開口部５が空間となっているので、ベロフラム４０は棒状部材１１の移動に応じてその開口部５内で弾性変形できるようになっている。即ち、環境試験用治具１００においては、シリンダ２１、メインパッキン２２、ベロフラム４０が気密保持手段として機能することとなる。 In the environmental test jig 100, for example, when the rod-shaped member 11 is moved in the forward direction of the user, the first fixing portion 401 of the bellophram 40 moves in that direction, and the inside of the opening 5 of the thermostat 2 is bellophram. The inside of the 40 folded portions 402 will move. That is, since the opening 5 is a space, the belofram 40 can be elastically deformed in the opening 5 in accordance with the movement of the rod-shaped member 11. That is, in the environmental test jig 100, the cylinder 21, the main packing 22, and the belofram 40 function as an airtight holding means.

この環境試験用治具１００によれば、恒温槽２の壁部４とベロフラム４０を直接気密固定して、部品点数を最小限にすることにより、コストを抑えることができる。また、その他にも環境試験用治具１０と同様の効果が得られる。 According to the environmental test jig 100, the wall portion 4 of the thermostat 2 and the belofram 40 can be directly hermetically fixed to minimize the number of parts, thereby reducing the cost. In addition, the same effects as the environmental test jig 10 can be obtained.

なお、本発明に係る環境試験用治具は、上述した実施形態に限られるものではない。上記実施例においては、環境試験用治具を複合環境加振機に適用しているが、これに限るものではなく、内部に配置された供試体に所定の温度環境及湿度環境のうち、少なくとも何れか一方を付与可能な箱体を備え、該箱体の壁部に開口部を有する環境試験装置であれば適用することができる。 The environmental test jig according to the present invention is not limited to the above-described embodiment. In the above embodiment, the environmental test jig is applied to the composite environmental shaker. However, the present invention is not limited to this, and at least of a predetermined temperature environment and humidity environment in the specimen placed inside. Any environmental test apparatus including a box that can be provided with either one and having an opening in the wall of the box can be applied.

また、上記実施形態においては、恒温槽の開口部にスポンジゴムを挿入することに伴って、支持部にスペーサを設けて、棒状部材のストローク移動を確保しているが、スペーサを設ける代わりに、スポンジゴムの一部を切り欠いて、棒状部材のストローク移動を確保して、棒状部材を供試体方向に移動させることも可能である。
その他、支持部やスペーサ等の孔部の径、恒温槽の開口部の大きさや、メインパッキンの気密固定の仕方、環境試験用治具を複合環境加振機に取り付ける工程の順序についても、本発明の趣旨を逸脱しない範囲で適宜変更可能である。 Further, in the above embodiment, along with the insertion of sponge rubber into the opening of the thermostatic chamber, a spacer is provided in the support portion to ensure the stroke movement of the rod-shaped member, but instead of providing the spacer, It is also possible to cut out a part of the sponge rubber to ensure the stroke movement of the rod-like member and move the rod-like member in the direction of the specimen.
In addition, the diameter of the holes such as the support and spacer, the size of the opening of the thermostatic chamber, how to fix the main packing in an airtight manner, and the order of the steps for attaching the environmental test jig to the combined environmental shaker It can change suitably in the range which does not deviate from the meaning of invention.
