The invention relates to an impact device for impact operation and a machine tool. The impact device comprises a power drive output part, an impact part, an impact transmission part, a guidance part and a biasing part, wherein the power drive output part provides power and is provided with a reciprocating motion part; the reciprocating motion part outputs reciprocating motion, so that the impact part is enabled to do reciprocating motion along the impact operation direction; a first acting force is applied onto the impact transmission part, so that the impact operation is implemented on a processed object; the guidance part at least guides the reciprocating motion part and the impact transmission part; the biasing part is associated with the reciprocating motion part; the biasing part is designed to enable the reciprocating motion part to apply a second acting force onto the impact transmission part directly or through the guidance part; and the direction of the second acting force is the same as the direction of the first acting force. By the adoption of the impact device for the impact operation and the machine tool, the hammering missing prevention capability can be improved, the impact counterforce is effectively absorbed, the service life is prolonged and the conformability is improved.
Description
technical field [0001] The present invention relates to an impact device, in particular to an impact device for performing impact operations and a machine tool provided with the impact device, especially a hand-held machine tool such as a hand-held hammer drill or an impact hammer. Background technique [0002] In the prior art, the impact device for impacting the processing object usually includes an element called an anvil (Anvil) or shim, which can be axially moved and guided in the guide part, And the guide part is usually relatively fixed with the whole machine tool and cannot produce relative movement in the impact direction, and contains a driving motor on the driving side, and the rotation of the driving motor is converted into the reciprocating motion of the piston through the reciprocating motion conversion mechanism. An impact hammer (Hammer) is set between the anvil iron or the shim iron, and a closed air spring can be formed between the impact hammer and the pis...
