The invention discloses a
cutting tool device with an eccentric balance mechanism. The
cutting tool device with the eccentric balance mechanism comprises a power mechanism, an eccentric wheel mechanism, a connecting rod
assembly and a
cutting tool. The power mechanism is in transmission connection with the eccentric wheel mechanism, the eccentric wheel mechanism is connected with the cutting toolthrough the connecting rod
assembly, and the eccentric wheel mechanism is provided with the balance mechanism. In the
cutting tool device with the eccentric balance mechanism, a spindle motor transmits rotation motion through a gear or a synchronous belt, the eccentric wheel mechanism converts the rotation motion into
reciprocating motion through the connecting rod
assembly, large-
stroke reciprocating motion is realized, and thud the production efficiency is improved. As the eccentric wheel mechanism is provided with the balance mechanism, the
resultant force
gravity center point C of a firstbalance
gravity center A which is composed of the connecting rod assembly in cup joint with an eccentric
inertia shaft and a first balancing weight block and a second balance
gravity center B which iscomposed of the first balance gravity center A and a
balance wheel device is always located on the circle center of an eccentric spindle, the unbalanced force on the eccentric
inertia shaft is eliminated, and the vibration and
noise caused by
centrifugal force during high-speed rotation are reduced.
