摘要:
An impact driver (1) with a vibration mechanism (90) includes a vibration switching ring (97) externally fitted to a second cam (93) in the forward position in such a manner that an inner protrusion (99) on the inner circumference is latched a protrusion (96) on the outer circumference of the second cam (93) so that the rotation of the second cam (93) is restricted. Further, a coil spring (100) is provided for biasing the vibration switching ring (97) to the forward position. A link plate provided between the mode switching ring (64) and the vibration switching ring (97) latches onto the front surface of the vibration switching ring (97) and engages an engaging protrusion (105) at the rear end with the mode switching ring (64). The link plate moves forward or backward to a first position where the vibration switching ring (97) moves to the forward position or a second position where the vibration switching ring (97) moves to the backward position.

A power tool includes a housing, a motor supported in the housing, a chuck assembly (30) having a chuck body (34) rotatable about a central axis in response to torque received from the motor, and a plurality of jaws (42) supported in the chuck body. Each of the jaws includes a front portion (82) operable to grasp a tool element and a rear portion (86) positioned outside the chuck body (34). The power tool also includes a hammer (170) mechanism operable to impart movement to the chuck assembly (30), in a direction parallel to the central axis, during rotation of the chuck assembly (30) about the central axis.
摘要:
A hammer drill/driver (10) with a motor (14) having an output member (20), a planetary transmission (16), a clutch assembly (18) and a clutch bypass. The planetary transmission, which includes a ring gear (310), receives rotary power from the output member (44) and produces a rotary output (460). The clutch assembly (18) has a clutch profile (316), which is coupled to the ring gear (310), and a first pin assembly (702) having a first follower (740), a first pin member (720) and a first spring (722) that biases the first follower (740) into contact with the clutch profile (316). The clutch bypass (18b) has a bypass profile, which is coupled to the ring gear (316), and second pin assembly having a second follower, a second pin member, a third spring, which biases the second follower away from the bypass profile, and a fourth spring, which biases the second follower away from the second pin member. A method for operation of a hammer drill/driver is also provided.

A power tool has an application mechanism (300) for connection to the output of an epicyclic gearbox provided with a torque control ring. The mechanism has a body (310) journalling a chuck spindle (302). Outside the body is a clutch control arrangement comprising balls (334,336) pressed against the torque control ring by individual springs (330) controlled by a control ring (322) threaded on the body. The mechanism includes a hammer arrangement having rotary and fixed ratchet plates (378,376) and cam ring (308) operable to engage and separate the plates by a lever (360) which projects between the springs (330).

Das Gerät zum Eintreiben von Befestigungselementen (12) in harte Werkstoffe weist eine Drehbohreinrichtung (1) und eine Bolzensetzeinrichtung (2) auf. Auf die Befestigungselemente (12) wird zum Erstellen eines Sackloches im Werkstoff in einer ersten Phase eine Drehbewegung mit gegebenenfalls überlagerter Schlagbewegung übertragen. Im Anschluss daran werden in einer zweiten Phase die Befestigungselemente (12) mittels hochgespannter Gase in ihre Endlage im Werkstoff eingetrieben.
摘要:
An impactor is externally securable to a container of flowable material to break up bridging or clumping of the material in the container. The impactor comprises a strike plate mountable to an outlet hopper or the like and a drive which axially reciprocally moves the hammer, such that operation of the drive causes the hammer to impact the strike plate to thereby pass vibrations into the container.
