DRIVING DEVICE, DRIVING MACHINE AND DRIVING METHOD
To provide a driving device, a driving machine and a driving method capable of reducing the possibility of contamination around the driving device during the driving work of a driving object.SOLUTION: A driving device 2 comprises a hammer portion 21, which has a striking piston in a cylinder that can reciprocate in the axial direction using compressed air as a power source, a movable joint portion 23, which is inserted into the hammer portion 21 so as to move forward and backward, and a chuck portion 25 having a connecting portion with the movable joint portion 23 and a sandwiching portion capable of sandwiching the object to be driven. The movable joint portion 23 has a connecting shaft to be fitted and inserted into the cylinder and a connected portion provided at the tip of the connecting shaft. The connecting shaft is provided with a first ventilation path in which a first opening hole communicating with the outside of the cylinder and a second opening hole opened in the opposite direction are formed, and a second ventilation path in which a third opening hole communicating with the first ventilation path and a fourth opening hole communicating with the gap between the connecting shaft and the fitting insertion portion are formed.SELECTED DRAWING: Figure 1
【課題】打設対象物の打設作業時における打設装置の周囲の汚染可能性を低減可能な打設装置、打設機及び打設方法を提供する。【解決手段】打設装置２は、圧縮空気を動力源として軸方向に往復動可能な打撃ピストンをシリンダー内に有するハンマ部２１、ハンマ部２１に進退動可能に嵌挿された可動継手部２３、及び、可動継手部２３との接続部及び打設対象物を挟持可能な挟持部を有するチャック部２５を備える。可動継手部２３は、シリンダー内に嵌挿する接続軸及び該接続軸の先部に設けられた被接続部を有し、接続軸には、シリンダー外に連通した第１開口孔及びその反対方向に開口した第２開口孔が形成された第１通気路と、第１通気路と連通した第３開口孔及び接続軸と被嵌挿部の間の空隙と連通した第４開口孔が形成された第２通気路が設けてある。【選択図】図１
