FIELD: process engineering. ^ SUBSTANCE: invention relates to impact tool, namely, to vibration damper in mechanised toll with linear drive of the tip. Proposed tool comprises motor, rotary shaft, swinging element, tool drive and counterweight. Motor-driven rotary shaft is arranged parallel with the tip axial direction. Swinging element is supported by rotary shaft to swing axially driven by rotary shaft. Tool drive mechanism is coupled with swinging element upper part in vertical direction. Tool drive mechanism causes linear displacement in the tip axial direction due to swinging element swings that linearly drive the tip. Counterweight is arranged in area above swinging element lower end in vertical direction that crosses rotary shaft axis. Counterweight is coupled with swinging element lower end. Counter weight is elongated upward from connection between counterweight and swinging element and has pivot point at elongated end section. ^ EFFECT: reduced vibration of tip in axial direction. ^ 9 cl, 17 dwg |
