Description
【0001】[0001]
この考案は、加圧オイル等の作動流体をシリンダに流出入させることにより平 行に開閉する平行開閉装置に関する。 The present invention relates to a parallel opening / closing device that opens and closes in a horizontal direction by letting a working fluid such as pressurized oil flow into and out of a cylinder.
【0002】[0002]
従来、前記平行開閉装置として、それぞれの歯が単一のピニオンと歯合する一 組のラックにそれぞれ作動部材が固定されて、該作動部材の一方がシリンダ内を 摺動する一つのピストンの作動軸に連結されたものがある。 前記開閉装置は、ピストンの摺動に応じて、該ピストンの作動軸に連結された 一方の作動部材および該作動部材に固定された一方のラックがピストンと同方向 に動き、そのラックと歯合するピニオンの回転により、他方のラックおよびその ラックに固定された他方の作動部材が、前記一方の作動部材とは反対方向に動い て両作動部材が平行に開閉する。 Conventionally, as the parallel opening / closing device, an operating member is fixed to a pair of racks, each tooth of which meshes with a single pinion, and one operating member slides in a cylinder to operate one piston. Some are connected to the shaft. In the opening / closing device, one operating member connected to an operating shaft of the piston and one rack fixed to the operating member move in the same direction as the piston in accordance with sliding of the piston, and mesh with the rack. The rotation of the pinion causes the other rack and the other actuating member fixed to the rack to move in the opposite direction to the one actuating member so that both actuating members open and close in parallel.
【0003】[0003]
しかし、前記の平行開閉装置にあっては、一つのピストンの摺動による直接の 力は作動部材の一方のみに加わり、他方の作動部材にはラックおよびピニオンを 介した間接的な力しか加わらない。そのため、両作動部材に加わる力は均等にな りにくく、ラックとピニオン部分にねじれの力が発生して作動部材が円滑に開閉 しないことが往々にしてあった。 そこでこの考案は、常に円滑に開閉する平行開閉装置の提供を目的とする。 However, in the parallel opening / closing device described above, the direct force by the sliding of one piston is applied only to one of the operating members, and the other operating member is only indirectly applied via the rack and the pinion. .. As a result, the forces applied to both actuating members are less likely to be uniform, and the actuating members often do not open and close smoothly due to the twisting force generated in the rack and pinion portions. Therefore, an object of the present invention is to provide a parallel opening / closing device that always opens and closes smoothly.
【0004】[0004]
前記目的を達成するため、この考案は、作動流体の流出入口を中央部と両端部 に有する単一のシリンダ内に二つのピストンが互いに接近離間するように配置さ れ、前記ピストンの各作動軸がそれぞれの作動部材と連結されて、前記各作動部 材にそれぞれの歯部が単一のピニオンと歯合するラックがそれぞれ設けられた構 成の平行開閉装置としたのである。 In order to achieve the above-mentioned object, the present invention is arranged such that two pistons are arranged close to and away from each other in a single cylinder having a working fluid outlet / inlet at a central portion and both end portions, and each working shaft of the piston is disposed. Is connected to each operating member, and each operating member is provided with a rack in which each tooth portion meshes with a single pinion.
【0005】[0005]
この考案の平行開閉装置にあっては、作動部材の各々がピストン各々の作動軸 と連結されている。そのため、作動部材各々には、ピストン各々の摺動による力 が均等に加わり、ラックおよびピニオン部でねじれの力が発生しにくく、作動部 材が円滑に開閉する。 In the parallel opening / closing device of the present invention, each of the operating members is connected to the operating shaft of each piston. Therefore, the force caused by the sliding of each piston is evenly applied to each of the operating members, and the twisting force is unlikely to be generated in the rack and the pinion portion, so that the operating member can be smoothly opened and closed.

The cylinder 12 has inlets, outlets 22, 23 and 24 for working fluid such as pressurized oil at the center and both ends of the upper part, and two pistons 26 and 28 are arranged inside the cylinder 12 so as to approach and separate from each other. Has been done. The facing surfaces of the two pistons 26, 28 are smaller than the inner diameter of the cylinder 12 so that the pistons 26, 28 do not block the working fluid outflow port 22 at the center of the cylinder when the pistons 26, 28 approach each other. It has become. Further, on the opposite surfaces of the two pistons 26, 28, operating shafts 30, 32 extending in the longitudinal direction of the cylinder 12 are provided. The ends of the operating shafts 30 and 32 respectively project from the operating shaft insertion holes at both ends of the cylinder 12 to the outside of the cylinder 12 and are connected to the operating members 34 and 36. The actuating members 34, 36 are plate-shaped members having a substantially L-shaped cross section with the lower ends bent inward, and the bent portions of the lower ends constitute the article gripping parts 35, 37. In the figure, 38 is a piston packing and 40 is a gasket.
【0008】 ラック14,16は、互いの歯がピニオン18に歯合するようにして、シリン ダ12と平行に摺動可能に設けられている。そして一方のラック14の一端部1 5が一方の作動部材36に、他方のラック16の反対端部17が他方の作動部材 34に各々連結されている。また、作動部材34,36に連結されていないラッ ク端部19,21は、各々の側に位置する作動部材34、36に形成されたラッ ク挿通穴42,44を通ってその作動部材34,36外側に伸びている。 なおピニオン18は、その回転軸が前記シリンダ12と直交してボディ11に 軸支されている。The racks 14 and 16 are slidably provided in parallel with the cylinder 12 so that the teeth of the racks 14 and 16 mesh with the pinion 18. One end portion 15 of one rack 14 is connected to one operating member 36, and the opposite end portion 17 of the other rack 16 is connected to the other operating member 34. The rack end portions 19 and 21 that are not connected to the actuating members 34 and 36 pass through the rack insertion holes 42 and 44 formed in the actuating members 34 and 36 located on the respective sides, and the actuating member 34. , 36 extends outward. The pinion 18 has its rotation axis orthogonal to the cylinder 12 and is pivotally supported by the body 11.
【0009】 また、二つのガイドロッド46,48は、作動部材34,36を、その開閉時 にガイドするためのもので、前記ラック14,16と平行にボディ11を貫通し て、一端が作動部材34,36に固定されている。The two guide rods 46 and 48 are for guiding the operating members 34 and 36 when opening and closing them, and penetrate the body 11 in parallel with the racks 14 and 16 so that one ends thereof are operated. It is fixed to the members 34 and 36.
【0010】 このようにしてなる平行開閉装置10は、把持部35,37で物品を把持する 際に、図1のようにシリンダ12上部の両端にある作動流体流出入口23,24 から加圧オイル等の作動流体50,50が、シリンダ12内のピストン26,2 8背部に流入される。それによりピストン26,28が作動流体50,50によ り背部から押されて、作動軸30,32とともにシリンダ12内の中央方向へ摺 動する。そしてその作動軸30,32と連結した作動部材34,36もシリンダ 12中央方向へ移動する。それにより作動部材端部の把持部35,37間隔が小 さくなって、その把持部35,37間で物品が把持される。 またその際、二つのピストン26,28間に存在していた作動流体52は、シ リンダ12中央の作動流体流出入口22からシリンダ12外へ流出される。In the parallel opening / closing device 10 thus configured, when gripping an article with the grip portions 35 and 37, pressurized oil is supplied from the working fluid outflow ports 23 and 24 at both ends of the upper portion of the cylinder 12 as shown in FIG. Working fluid 50, 50, etc., flows into the back of the piston 26, 28 in the cylinder 12. As a result, the pistons 26, 28 are pushed from the back by the working fluids 50, 50 and slide together with the working shafts 30, 32 toward the center of the cylinder 12. The operating members 34 and 36 connected to the operating shafts 30 and 32 also move toward the center of the cylinder 12. As a result, the gap between the grips 35 and 37 at the end of the operating member is reduced, and the article is gripped between the grips 35 and 37. At that time, the working fluid 52 existing between the two pistons 26, 28 flows out of the cylinder 12 through the working fluid outflow port 22 at the center of the cylinder 12.
【0011】 一方、把持部35,37による物品の把持解除を行なう際には、図2のように シリンダ12中央の作動流体流出入口22から加圧オイル等の作動流体52が、 シリンダ12内の二つのピストン26,28間に流入される。それにより二つの ピストン26,28が、作動流体52によりシリンダ12両端方向に押されて作 動軸30,32とともにシリンダ12両端方向へ摺動し、作動部材34,36端 部の把持部35,37が開く。 また、それまでピストン26,28背部のシリンダ12内に存在していた作動 流体50は、シリンダ両端の作動流体流出入口23,24からシリンダ12外に 流出される。On the other hand, when the gripping of the article by the gripping portions 35 and 37 is performed, the working fluid 52 such as the pressurized oil is discharged from the working fluid outlet / inlet 22 in the center of the cylinder 12 as shown in FIG. It is introduced between the two pistons 26 and 28. As a result, the two pistons 26, 28 are pushed by the working fluid 52 toward both ends of the cylinder 12 and slide together with the operating shafts 30, 32 toward both ends of the cylinder 12, and the grips 35, 37 opens. The working fluid 50, which has been present in the cylinder 12 at the back of the pistons 26, 28, flows out of the cylinder 12 through the working fluid outflow ports 23, 24 at both ends of the cylinder.
【0012】 前記物品の把持時および把持解除時、両作動部材34,36にはピストン26 ,28から作動軸30,32を介して均等に力が加わるため、作動部材34,3 6が円滑に開閉する。また、ラック14,16とピニオン18は、両作動部材3 4,36の開閉のタイミングを調節するととともに、その開閉時に両作動部材3 4,36のガイドをするため、それによっても両作動部材34,36が円滑に開 閉することになる。At the time of gripping and releasing the grip of the article, force is evenly applied from the pistons 26 and 28 to the operating members 34 and 36 via the operating shafts 30 and 32, so that the operating members 34 and 36 are smoothly moved. Open and close. Further, the racks 14 and 16 and the pinion 18 adjust the opening and closing timings of both operating members 34 and 36, and guide the operating members 34 and 36 at the time of opening and closing, so that both operating members 34 and 36 are also guided. , 36 will open and close smoothly.
