摘要： An air motor has a rotor rotatable in response to the pressure of pressurized air. A cylindrical rotary member is connected to the air motor for causing a rotation in synchronism with the rotation of the rotor. A rotary slider is slidable in the axial direction along the inner cylindrical wall of the rotary member. A rotational force transmitting mechanism is provided for transmitting the rotation of the rotary member to the rotary slider. A shaft has one end fixed to the rotary slider and the other end equipped with a piston and a driver bit holder. The rotational and axial motion of the rotary slider is transmitted to a driver bit held in the driver bit holder. And, a cylinder guides the axial slide movement of the piston responsive to the pressure of pressurized air applied on a pressure-receiving surface of the piston.

摘要： A main valve and a manual operating valve cooperatively control the compressed air supplied to an air motor and a piston. The main valve is responsive to the compressed air supplied from the manual operating valve via an air passage. An orifice is provided in the air passage to reduce the speed of the compressed air supplied to the main valve so that the shift movement of the main valve is delayed when the manual operating valve is closed.

摘要： A pneumatically operated screw driver ensuring a complete return of a piston to its top dead center. The screw driver has a compressed air return chamber for returning the piston to its top dead center by applying a compressed air in the return chamber to the piston. The piston includes a main piston and an auxiliary piston. The main piston is first reaches its bottom dead center, and then the auxiliary piston reaches its bottom dead center whereupon screw driving is terminated. Before the auxiliary piston reaches its bottom dead center, and after the main piston moves past a predetermined position, a compressed air is introduced into the return chamber. After the main piston reaches the bottom dead center, application of the compressed air pressure in the return chamber to the auxiliary piston is prevented.

摘要： A pneumatically operated screw driver driven by a compressed air to drive screws into a workpiece. A drive bit connecting portion is rotated in a right-hand direction by rotation of a pneumatic motor and is formed with a right-handed threaded hole. A drive bit is formed at one end with a right-handed male threaded screw and at the other end with an engagement tip that engages with screws that are to be screwed into the workpiece. The drive bit is engaged with the drive bit connecting portion through threading engagement of the right-handed threaded hole and the righted-handed male threaded screw. For detaching the drive bit from the drive bit connecting portion, a rotation prevention mechanism prevents free rotation of the drive bit connecting portion. In this state, the engagement tip of the drive bit is engaged with an external tool. By rotating the external tool in a counterclockwise direction while preventing the rotation of a main body of the screw driver, the drive bit is disengaged from the drive bit connecting portion.
摘要翻译：由压缩空气驱动的气动螺杆驱动器将螺丝驱动到工件中。驱动钻头连接部通过气动马达的旋转沿右手方向旋转，并且形成有右旋螺纹孔。驱动钻头在一端用右旋内螺纹螺钉形成，另一端用与要拧入工件的螺钉啮合的啮合末端形成。通过右旋螺纹孔和右旋内螺纹螺纹的螺纹接合，驱动钻头与驱动钻头连接部分接合。为了从驱动钻头连接部分拆下驱动钻头，防止旋转的机构阻止驱动钻头连接部分的自由旋转。在这种状态下，驱动钻头的啮合端与外部工具接合。通过在防止螺丝刀的主体的旋转的同时沿逆时针方向旋转外部工具，驱动钻头与驱动钻头连接部分脱离啮合。

摘要： Two guide members cooperatively constitute a chuck portion for holding a screw head. Opening and closing of the chuck portion is regulated depending on a mutual position between a machine body and a member into which a screw is driven. Guide pin portions of respective guide members engage with a stopper portion of a push lever until a screw is driven to a predetermined depth. The chuck potion tightly holds the screw head until a screw fastening operation is substantially finished, thereby suppressing the lifting of a machine body.

摘要： A compact and light-weight pneumatically operated screw driver providing high speed screw fastening with high operability. A rotary member rotationally driven by a pneumatic motor includes a main rotary member made from a plastic material and a sliding segment fixed to the main rotary member. A rotation slide member is axially slidably movable relative to the rotary member and is rotatable together with the rotation of the rotary member. A shut-off section is provided on which the rotation slide member is rotationally seated when the rotation slide member is moved toward the shut-off section. The rotation slide member is made from an elastic material. A sleeve like piston having a seal ring in sliding contact with a cylinder is provided. The seal ring shuts off a supply of compressed air to the pneumatic motor only by the seating of the rotation slide member onto the shut-off section.
