図5は従来の打込機の一例を示すものである。従来の打込機は、トリガ2の操 作により動作するスイッチ3と、該スイッチ3により開閉動作するヘッドバルブ 4と、シリンダ7内を往復動して止具5を打撃するピストン6からなり、駆動部 は蓄圧室8、シリンダ室9、戻り室10の3つの空気室からなり、蓄圧室8と戻 り室10はシリンダプレート11によって分割され、該シリンダプレート11は 止めワッシャ12によって固定されていた。 FIG. 5 shows an example of a conventional driving machine. A conventional driving machine includes a switch 3 which is operated by operating a trigger 2, a head valve 4 which is opened and closed by the switch 3, and a piston 6 which reciprocates in a cylinder 7 to strike a stopper 5. The drive unit consists of three air chambers, a pressure storage chamber 8, a cylinder chamber 9, and a return chamber 10. The pressure storage chamber 8 and the return chamber 10 are divided by a cylinder plate 11, and the cylinder plate 11 is fixed by a stop washer 12. It was

図5に示す駆動部を備えた打込機では、使用する止具5の大きさや被打込材に 打込むのに必要な出力等から蓄圧室8、シリンダ室9、戻り室10の3つの空気 室の容積が決まってしまい、該3つの空気室の容積を小さくするのが困難なため 結果的に打込機を小型軽量化するのが困難であった。 本考案の目的は、上記問題点を解決し、小型軽量の打込機を提供することであ る。 In the driving machine equipped with the driving unit shown in FIG. 5, three types of pressure accumulating chamber 8, cylinder chamber 9 and return chamber 10 are selected depending on the size of the stopper 5 used and the output required for driving the material to be driven. Since the volumes of the air chambers are determined and it is difficult to reduce the volumes of the three air chambers, it was difficult to reduce the size and weight of the driving machine as a result. An object of the present invention is to solve the above problems and provide a compact and lightweight driving tool.

上記目的は前記シリンダプレートを上下摺動可能に設けると共に、該シリンダ プレートを常時蓄圧室側に押圧するスプリングを設置することにより達成される 。 The above object can be achieved by providing the cylinder plate so as to be slidable in the vertical direction and installing a spring for constantly pressing the cylinder plate toward the pressure accumulating chamber.
【0005】[0005]
上記のように構成された駆動部において、ピストン上昇時(打撃前)シリンダ プレートは戻り室側に移動し、止具打撃に必要な所定の蓄圧室容積を確保する。 またピストン下降時(打撃後)シリンダプレートは蓄圧室側に移動し、ピストン が戻るのに必要な所定の戻り室容積を確保する。 In the drive unit configured as described above, the cylinder plate moves to the return chamber side when the piston rises (before striking), and secures a predetermined accumulator chamber volume necessary for striking the stopper. The cylinder plate moves to the pressure accumulator side when the piston descends (after striking), and secures the predetermined return chamber volume necessary for the piston to return.

本考案の一実施例を図1〜図4を用いて説明する。 図において、打込機本体1内には円筒状のシリンダ7が設けられており、シリ ンダ7内には上下摺動可能にピストン6が設けられている。更にピストン6外周 にはピストンリング14を設け、シリンダ7とピストン6との間をシールしてい る。またシリンダ7上端にはヘッドバルブ4を有しており、トリガ2を引いてス イッチ3が入るとヘッドバルブ4が上昇してシリンダ7上端が開き蓄圧室8とシ リンダ室9が連通すると共に排気部15が閉じシリンダ室9と大気を遮断する。 またトリガ2を戻してスイッチ3が切れるとヘッドバルブ4が下降して、シリン ダ7上端が閉じて排気部15が開き、シリンダ室9のピストン6上部が大気に連 通する。 An embodiment of the present invention will be described with reference to FIGS. In the figure, a cylindrical cylinder 7 is provided in the driving machine body 1, and a piston 6 is provided in the cylinder 7 so as to be vertically slidable. Further, a piston ring 14 is provided on the outer circumference of the piston 6 to seal between the cylinder 7 and the piston 6. Further, a head valve 4 is provided at the upper end of the cylinder 7, and when the trigger 2 is pulled and the switch 3 enters, the head valve 4 rises, the upper end of the cylinder 7 opens, and the accumulator chamber 8 and the cylinder chamber 9 communicate with each other. The exhaust unit 15 is closed to shut off the air from the cylinder chamber 9. When the trigger 2 is returned and the switch 3 is turned off, the head valve 4 descends, the upper end of the cylinder 7 closes and the exhaust part 15 opens, and the upper part of the piston 6 in the cylinder chamber 9 communicates with the atmosphere.
【0007】 一方シリンダ7下部周囲には戻り室10があり、該戻り室10とシリンダ室9 は通路16により連通しており、更に戻り室10とシリンダ室9はシリンダ室9 から戻り室10へ一方向のみ空気が通過する通路17により連通している。また シリンダ7外周には、蓄圧室8と戻り室10を隔離するためのシリンダプレート 11が設けてあり、シリンダプレート11は通路17と止めワッシャ12間を摺 動可能に設置されていると共に、スプリング13により蓄圧室8側に常時押圧さ れている。シリンダプレート11は本体1を空気圧縮機等の圧縮空気源につなぎ 、蓄圧室8に圧縮空気が充填されるとスプリング13の押圧力より蓄圧室8圧力 が大となり、シリンダプレート11は戻り室10側に移動する。またピストン6 下降時は蓄圧室8の圧力より戻り室10内の圧力とスプリング13押圧力の合力 が大となり、シリンダプレート11は蓄圧室8側に移動する。On the other hand, there is a return chamber 10 around the lower part of the cylinder 7, and the return chamber 10 and the cylinder chamber 9 communicate with each other through a passage 16. Further, the return chamber 10 and the cylinder chamber 9 are transferred from the cylinder chamber 9 to the return chamber 10. The passages 17 allow air to pass in only one direction. A cylinder plate 11 for isolating the pressure accumulating chamber 8 and the return chamber 10 is provided on the outer periphery of the cylinder 7, and the cylinder plate 11 is slidably installed between the passage 17 and the stopper washer 12 as well as the spring. It is constantly pressed to the pressure accumulating chamber 8 side by 13. The cylinder plate 11 connects the main body 1 to a compressed air source such as an air compressor, and when the pressure accumulating chamber 8 is filled with compressed air, the pressure of the pressure accumulating chamber 8 becomes larger than the pressing force of the spring 13, and the cylinder plate 11 becomes the return chamber 10 Move to the side. Further, when the piston 6 descends, the resultant force of the pressure in the return chamber 10 and the pressing force of the spring 13 becomes larger than the pressure in the pressure accumulating chamber 8, and the cylinder plate 11 moves to the pressure accumulating chamber 8 side.
【0008】 上記した構造において動作を説明する。図2は本体1を圧縮空気源につないで いない状態を示すものであり、シリンダプレート11はスプリング13の押圧力 により蓄圧室8側に移動している。次に図3に示すように本体1を圧縮空気源に つなぐと、スプリング13の押圧力より蓄圧室8内に充填された圧力が大となり 、シリンダプレート11が戻り室10側に移動して蓄圧室8が止具5を打込むの に必要な所定の容積となる。The operation of the above structure will be described. FIG. 2 shows a state in which the main body 1 is not connected to the compressed air source, and the cylinder plate 11 is moved to the pressure accumulating chamber 8 side by the pressing force of the spring 13. Next, as shown in FIG. 3, when the main body 1 is connected to the compressed air source, the pressure filled in the pressure accumulating chamber 8 becomes larger than the pressing force of the spring 13, and the cylinder plate 11 moves to the return chamber 10 side to accumulate the pressure. The chamber 8 has a predetermined volume required to drive the stopper 5.
【0009】 図4は止具5を打込んだ時の状態を示すものであり、トリガ2を引くとスイッ チ3が入りヘッドバルブ4が上昇して蓄圧室8とシリンダ室9が連通し、蓄圧室 8内の圧縮空気がシリンダ室9内に急速に流入してピストン6が下降し止具5を 打撃する。一方シリンダ室9内のピストン6下側の空気は通路16から戻り室1 0に流入し、ピストンリング14が通路17を通過すると、シリンダ室9内に流 入した圧縮空気が通路17から戻り室10に流入するため、蓄圧室8の圧力より 戻り室10の圧力とスプリング13の合力が大となり、シリンダプレート11は 蓄圧室8側に移動して、ピストン6を戻すのに必要な戻り室10の容積が確保さ れる。次にトリガ2を戻すとスイッチ3は切れてヘッドバルブ4が下降し、排気 部15からシリンダ7内のピストン6上側の圧縮空気が排気される。ピストン6 は通路16を通った戻り室10の圧縮空気により押し戻される。戻り室10内の 圧力が下がるため、スプリング13の押圧力より蓄圧室8の圧力が大となり、シ リンダプレート11は戻り室10側に移動し図3の状態となる。FIG. 4 shows a state in which the stopper 5 is driven in. When the trigger 2 is pulled, the switch 3 enters and the head valve 4 rises so that the pressure accumulating chamber 8 and the cylinder chamber 9 communicate with each other. The compressed air in the pressure accumulating chamber 8 rapidly flows into the cylinder chamber 9 and the piston 6 descends to strike the stopper 5. On the other hand, the air below the piston 6 in the cylinder chamber 9 flows into the return chamber 10 from the passage 16, and when the piston ring 14 passes through the passage 17, the compressed air flowing into the cylinder chamber 9 returns from the passage 17 to the return chamber. Since the pressure flows into the pressure accumulating chamber 8, the pressure in the return chamber 10 and the resultant force of the spring 13 become larger than the pressure in the accumulating chamber 8, and the cylinder plate 11 moves to the pressure accumulating chamber 8 side and is necessary to return the piston 6 to the return chamber 10. The volume of is secured. Next, when the trigger 2 is returned, the switch 3 is turned off, the head valve 4 is lowered, and the compressed air above the piston 6 in the cylinder 7 is exhausted from the exhaust portion 15. The piston 6 is pushed back by the compressed air in the return chamber 10 passing through the passage 16. Since the pressure in the return chamber 10 is lowered, the pressure in the pressure accumulating chamber 8 becomes larger than the pressing force of the spring 13, and the cylinder plate 11 moves to the return chamber 10 side and becomes the state of FIG.

本考案によれば、シリンダプレートが移動する容積を蓄圧室と戻り室で共有で きるようにしたので、共有できる容積分、蓄圧室及び戻り室を小さくすることが でき、打込機を小型軽量化することができる。また蓄圧室と戻り室を従来の大き さのまま本考案を採用した場合、従来の打込機の出力と比較して共有できる容積 分出力を上げることができる。 According to the present invention, since the volume in which the cylinder plate moves can be shared by the pressure accumulating chamber and the return chamber, the pressure accumulating chamber and the return chamber can be made smaller by the amount that can be shared, and the driving tool is small and lightweight. Can be converted. Further, when the present invention is adopted with the accumulator chamber and the return chamber being the same size as the conventional one, it is possible to increase the volumetric output that can be shared as compared with the output of the conventional driving machine.
