  • Publication number: 20240189884
    Abstract: A tube expansion tool includes a female screw member that rotates by an electric motor. A screw shaft engages the female screw member to move in a front-rear direction. A front-end position sensor detects that the screw shaft has reached a front-end position. The screw shaft stops moving forward by a braking operation. A controller controls the braking operation of the electric motor. When the controller determines that the screw shaft has reached the front-end position based on a signal from the front-end sensor, the controller performs the braking operation. Also, when the controller detects that the screw shaft stops, the controller rotates the electric motor in a reverse direction to move the screw shaft rearward.

  • Publication number: 20230226588
    Abstract: A tube expansion tool that expands an end portion of a synthetic resin made fluid pipe includes an electric motor that is housed in a main body housing. A screw shaft is located in the main body housing and is movable in a front-rear direction. A female screw member is configured to move the screw shaft in the front-rear direction by engaging with and rotating around the screw shaft. A gear that engages the female screw member transmits a rotation output of the output shaft of the electric motor to the female screw member. A wedge extends forward from the screw shaft. A plurality of jaws are coupled to the main body housing so as to be openable/closable. When the wedge moves forward integrally with the screw shaft, the plurality of jaws are pushed by the wedge so as to be opened radially outward relative to each other.

  • Publication number: 20230141074
    Abstract: A pipe expanding tool includes a wedge, a plurality of jaws, a spring and a first rotary member. The wedge is movable in a reciprocating manner between a first position and a second position along a first axis. The jaws are rotatable around the first axis and movable to a closed position and to an open position. The jaws are configured to move from the closed position to the open position as the wedge moves from the first position to the second position, and to move from the open position to the closed position as the wedge moves from the second position to the first position. The first rotary member is engaged with the jaws such that the first rotary member is integrally rotatable with the jaws, and is configured to be rotated only in one direction around the first axis by an elastic force of the spring.

  • Patent number: 11504764
    Abstract: A fastening tool includes a motor, a fastening mechanism, a tool body and a main handle. The motor includes a motor body and a motor shaft. The fastening mechanism is configured to fasten workpieces via a fastener by pulling a pin of the fastener rearward relative to a tubular part of the fastener along a driving axis defining a front-rear direction of the fastening tool. The tool body houses the motor and the fastening mechanism. The main handle extends in a direction crossing the driving axis and connected to the tool body such that the main handle and the tool body together form an annular part. A rotational axis of the motor shaft extends parallel to the driving axis. A portion of the main handle is located in a rear space extending behind the motor body.

  • Publication number: 20220324012
    Abstract: A fastening tool includes a housing, a handle, an anvil, a pin-gripping part, a motor, and a driving mechanism. The driving mechanism is configured to move the pin-gripping part along a first axis defining a front-rear direction, relative to the anvil. The driving mechanism includes a rotary member, a movable member, a driving gear and an idler gear. The rotary member has a driven gear formed on its outer periphery and is rotatable around the first axis. The movable member is connected to the pin-gripping part and configured to be linearly moved in the front-rear direction by rotation of the rotary member. The driving gear is configured to be rotated around a second axis extending in parallel to the first axis below the first axis. The idler gear is engaged with the driving gear and the driven gear.
