摘要： A powered hammer includes a housing, a tool holder coupled to the housing and configured to hold a tool, a motor within the housing, a piston slideably mounted within the housing, a drive mechanism that converts rotary output of the motor into a reciprocating motion of the piston, a ram slideably mounted forward of the piston and that is reciprocatingly driven by the piston, and a beat piece support mounted in the housing forward of the ram. A beat piece is slideably supported by the beat piece support. The beat piece is repetitively struck by the ram and that in turn repetitively strikes an end of a tool when the tool is held in the tool holder to transfer the momentum of the ram to a tool. The beat piece support includes a seal that is slidingly engaged by the beat piece. The seal includes an absorbent material.

摘要： A powered hammer includes a housing coupled to a tool holder having a front end, and including a motor, a cylinder, and a piston is slideably received within the cylinder. A drive mechanism converts rotary output of the motor into a reciprocating motion of the piston within the cylinder. A ram, slideably mounted within the cylinder forward of the piston, is reciprocatingly driven by the piston. A beat piece support structure supports a beat piece. The beat piece is repetitively struck by the reciprocating ram, which repetitively strikes an end of the tool to transfer momentum of the ram to the tool. The beat piece support structure allows the beat piece to slide between a first forward position and a second rearward position. When the powered hammer is not in operation, a first end of a rod having indicia located a predetermined distance from the first end can be inserted into the tool holder to slide the beat piece to the second rearward position so that a distance between the front end of the tool holder and the indicia indicates an amount of wear on the beat piece.

摘要： A powered hammer includes a housing, a tool holder coupled to the housing and configured to hold a tool, a motor within the housing, a cylinder disposed within the housing, and a piston slideably mounted within the cylinder. A drive mechanism converts rotary output of the motor into a reciprocating motion of the piston. The drive mechanism includes a crank shaft rotationally driven by the motor, a drive pin eccentrically mounted on the crank shaft, and a con rod with a first end connected to the drive pin and a second end connected to the piston. A ram is slideably mounted forward of the piston that is reciprocatingly driven by the piston. A beat piece is slideably mounted forward of the ram. The beat piece is repetitively struck by the reciprocating ram, which in turn repetitively strikes an end of the tool when held in the tool holder to transfer the momentum of the ram to the tool. Lubrication fluid covers at least part of the drive mechanism. A rear piston chamber is formed within an end of the cylinder, rearward of the piston, the volume of which repetitively changes as the piston moves within the cylinder, causing air within the housing to be at least one of drawn into and blown out of the rear piston chamber. The movement of air causes the lubrication fluid to move within the housing. A longitudinal passageway defined in at least one of the crank shaft and the drive pin enables passage of air and the lubricating fluid to assist in movement of the lubrication fluid within the housing.

摘要： A vibration reduction and lubricating mechanism for a powered hammer includes a power driven piston in a cylinder that reciprocatingly drives a ram, which repetitively strikes a beat piece, which repetitively strikes a tool received in a tool holder. The vibration reduction and lubricating mechanism includes a first chamber defined in a housing of the powered hammer. A second chamber is defined within an end portion of the cylinder facing the beat piece, forward of the ram. A passageway is in communication with the first and second chambers. A counter mass is mounted for oscillating movement within the first chamber. When the hammer is operated, the counter mass is caused to oscillate to counteract vibration in the housing and to cause lubrication fluid to move between the first and second chambers.

摘要： A motorized hammer has a body and a tool holder which is mounted on the front of the body and is capable of imparting impacts via the tool in the holder. A rear handle is, moveably mounted to the rear of the body via at least one movement control mechanism which is capable of moving towards or away from the body. A biasing mechanism biases the rear handle away from the body and each movement control mechanism includes a first mount. A rod having a longitudinal axis is rigidly connected at one of it ends to the first mount. A second mount slidingly engages with the rod at two distinct points only along its length to allow the rod to slide relative to the second mount in a direction parallel to the longitudinal axis. The second mount prevents the rod from moving in a direction perpendicular to the longitudinal axis.

摘要： A tool holder for a powered hammer includes a tool holder housing. An actuator is coupled to the tool holder housing and is moveable among a range of operating positions that include a first position where the actuator locks a tool within the tool holder by engaging a rib on the tool, a second position where the actuator locks a tool within the tool holder by engaging a recess in the tool, and a third position where the actuator allows a tool to be released from the tool holder. An actuator locking mechanism releasably locks the actuator in at least the third position.
