摘要： PROBLEM TO BE SOLVED: To provide a chisel handheld machine tool such as a handheld hammer drill or a handheld crusher, and a machine tool adapted to the handheld machine tool and suppressing a vibration impact.SOLUTION: A handheld machine tool includes a tool attachment port 2 for attaching a chisel tool on a motion axis 10. A pneumatic hammer mechanism 6 includes: an exciter 12 which reciprocates at a prescribed stroke 24 between a dead point 22 positioned apart from the tool rather than a motor 5 and a dead point 23 positioned near the motor; a hammer 13 which reciprocates on the motion axis 10 between a reversal point 29 positioned apart from the tool and an impact point 28; and an air chamber 15 which is sealed by the exciter 12 and the hammer 13, and transmits the motion of the hammer 13 to the motion of the exciter 12. When the exciter 12 moves to a direction in which the exciter progresses toward the dead point 22 positioned apart from the tool and approximates the dead point 22 positioned apart from the tool by a distance not reaching a half of an entire stroke 24, a control device 39 raises pressure in the air chamber 15.

摘要： PROBLEM TO BE SOLVED: To provide a portable or handheld machine tool for suppressing a vibration impact including a hammer mechanism which operates by compressed air such as an electric hammer drill and an electric chipper.SOLUTION: A handheld machine tool includes a tool attachment port for attaching a chisel tool on an operation axis 10. An air pressure hammer mechanism includes a hammer 13 which moves on the operation axis 10, and an air chamber 15 which is sealed by an exciter 12 and the hammer 13, and transmits the motion of the exciter 12 to the hammer 13. The exciter 12 is driven by a motor, and reciprocates between a front dead point positioned apart from the tool and a dead point positioned near the tool. A control device includes a supercharger 19 and a controlled output valve 32. When the exciter 12 approximates the dead point positioned apart from the tool, the controlled output valve 32 permits the flow-in of air into the air chamber 15 from the supercharger 19.

摘要： PROBLEM TO BE SOLVED: To provide a hand-held tool with an electromagnetic hammering mechanism achieving high impact energy efficiency in a relative lifetime. SOLUTION: A hand-held tool at least partly generating a hammering motion of a tool 3 along the oscillation axis A is provided with an electromagnetic hammering mechanism 1 with a stator, at least one coil 4a and a free piston arranged as a yoke 10 within the magnetic flux and restrictively movable along the oscillation axis A. The free piston has at least one penetrating area 11 consisted of soft magnetic ferromagnetic materials. At least one magnet 5a is arranged on the stator of the electromagnetic hammering mechanism 1 for being magnetized along the oscillation axis A, while being arranged along at least one segment of the coil 4a defined on the end of the stator. The coil 4a has the central axis B which is vertically extending against the oscillation axis A.

摘要： PURPOSE: To remarkably reduce the cost of a hammer drill by connecting one complete construction unit formed by an intermediate shaft and a hammering mechanism driving device and the other construction unit formed by a miter gear to each other through a second intermediate shaft. CONSTITUTION: A mechanical driving device for a drill hammer 1 is divided into two construction units 31, and a first construction unit of these construction units is formed by a hammering mechanism 3, a motion converting transmission device 16 and a first intermediate shaft 4. Further, a second construction unit 31 is formed by a miter gear 30, and these two construction units 31 are connected to each other through a second intermediate shaft 23 for torque transmission. The second intermediate shaft 23 is disposed parallel to the first intermediate shaft 4 on the side directing the hammering mechanism 3 of the first intermediate shaft 4.

摘要： PURPOSE: To provide strong striking force without utilizing a large-output motor by providing a nonuniform-velocity means setting the velocity of a piston larger in its forward path than in its return path. CONSTITUTION: A switch handle is operated with the tip of a drill bit 8 kept in contact with a bored face and with its rear end kept in contact with a striker 33 to operate a small-output motor 2, and the rotation of the motor 2 is transferred to the drill bit 8 from an intermediate shaft 23 via a spindle 31 and a key 39 to rotate the bit 8. A piston 4 is reciprocated by the cam action of the positive motion cam (constituted of the cam groove 56 of a rotor 55 and the roller 57 of the piston 4) of a motion converting member 5 concurrently serving as a nonuniform-velocity means 6. The velocity of the piston 4 is set larger in its forward path than in its return path, the striker 33 is driven by a hammer 41 with strong striking force, the striking force is transferred to the drill bit 8, and a large-diameter hole is bored on a work.
