Title:
HAND WORK INSTRUMENT DRIVEN BY ELECTRICITY
Document Type and Number:
Japanese Patent JPS5810469
Kind Code:
A
Abstract:
An electrically-operated manual device, such as a nail driver, has an electric motor for actuating an axially-movable impact body. The motor is a vibrating armature AC motor having a single-sided movably arranged vibrating armature which, in dependence of the power supply frequency, acts with a high impact frequency on a low-mass impact body. The impact body is located in a stationary cylinder connected to a housing of the device and has a detachable adapter sleeve which receives a plunger activated via the impact body on a part to be driven. The configuration of the device makes it possible to construct a nail driver or the like with an extremely compact structure since the cylinder equipped with the impact body can be arranged immediately adjacent the vibrating armature AC motor. The power losses are negligible because the vibrating armature, swinging about an axis, acts directly on the low-mass impact body. In addition, it is possible to construct adapter sleeves for connection to the cylinder for different driving applications.
