Impact tool

Номер: US20120024555A1
Автор: Hikaru Kamegai, Masanori Furusawa, Yoshio Sugiyama
Принадлежит: Makita Corp

Representative impact tool according to the invention includes a reaction force transmitting member 161 that receives a striking reaction force caused when a tool bit 119 strikes a workpiece, a first elastic member 163 that biases the reaction force transmitting member 161 forward, and a second elastic member 171 that is pushed by the reaction force transmitting member 161 and compressively deforms, thereby cushioning the striking reaction force, when the reaction force transmitting member 161 moves rearward by receiving the striking reaction force. When a user presses the tool bit 119 against the workpiece, the reaction force transmitting member 161 is pushed by the tool bit 119 and compresses the first elastic member 163, and also comes in contact with the second elastic member 171 in an incompressible state, so that the reaction force transmitting member 161 is placed in a predetermined working position in the longitudinal direction, and when the reaction force transmitting member receives the striking reaction force in the working position, the reaction force transmitting member moves rearward in the axial direction of the tool bit and compressively deforms the second elastic member 171, thereby cushioning the striking reaction force.

A hand tool impacting device may include, a drive shaft with an aperture, an impaler disk, and a floating pin positioned within the aperture of the drive shaft. A set of circular ramps on the outer edge of the impaler disk may interact with a stationary pin insert to translate the drive shaft and create an impacting motion. A pair of springs placed against either side of the floating pin may allow a specialized tool bit to engage or disengage the impaler disk, thereby allowing selective use of translational impacting motion, or rotational torque. An impact bit for engaging the impaler disk may include, a tool head configured to engage a work piece and a tool shaft configured to be inserted into a hollow drive shaft to engage a floating pin. According to one embodiment, the impact bit includes a number of sleeves to guide the tool head during operation.

A suction extraction device has a fan, a suction head, a channel leading from the suction head to the fan, a dust filter and a collection container to hold the dust that has been deposited on the dust filter. The suction head has a tubular cavity that is arranged around the working axis and that serves to accommodate the connection section of the suction drill bit. Arranged in the cavity is a flow sensor that has a sensor surface facing the working axis and that serves to emit a measuring signal that is indicative of the air flow that is striking the sensor surface. An evaluation unit emits an error signal in response to the measuring signal if the measuring signal is lower than a threshold value for at least a prescribed period of time, whereas it suppresses the error signal if the measuring signal exceeds the threshold value during the prescribed period of time.
