Problems solved by technology

First of all, the tool holder must be hollow, which limits the selectivity of the tool holder to a certain extent
Secondly, the cavity volume of the tool holder is fixed, so the number of internal particles is limited, and the damping effect produced will also be limited to a certain range
[0007] To sum up, in the prior art, there is still no effective solution to the problem of reducing the chatter of the turning tool holder

Abstract

The invention discloses a scattering type periodic structure damping vibration reducing lathe cutter rod. By means of the scattering type periodic structure damping vibration reducing lathe cutter rod, the problem of lathe cutter vibration in lathing is solved, vibration energy can be made to be attenuated in the lathing process, propagation of mechanical waves is inhibited, noise is reduced, themachining stability is improved, and the scattering type periodic structure damping vibration reducing lathe cutter rod is made to have vibration isolation performance within the forbidden band frequency range utilizing the frequency band gap characteristic of a periodic structure. The technical scheme of the scattering type periodic structure damping vibration reducing lathe cutter rod is that the scattering type periodic structure damping vibration reducing lathe cutter rod comprises a cutter rod base body and a cutter head which are connected into a whole, the peripheral surface of the cutter rod base body is evenly provided with multiple rows and columns of damping scattering bodies in a period distribution manner, the cutter rod base body and the damping scattering bodies form the scattering type periodic structure, in the lathing process, the vibration energy generated at the cutter head position is delivered to the damping scattering bodies, inhibiting effect is performed on elastic waves within the forbidden band range utilizing the damping scattering bodies, so that the vibration energy is converted into heat dissipation to realize inhibiting of lathing vibration.

Description

Technical field [0001] The invention relates to the technical field of cutting tools, in particular to a scatter type periodic structure damping vibration reduction turning tool bar. Background technique [0002] With the increasing requirements for product quality and precision in the machinery manufacturing industry, metal cutting methods have also been rapidly developed. Turning, which is the main processing method of metal processing, has also improved its technology in various aspects to achieve better processing quality and higher processing accuracy. Therefore, the requirements for processing tools have naturally increased. In the cutting process, the tool bar produces bending and chattering vibration under the action of cutting force, which makes the processing stability worse, seriously affects the processing quality and processing accuracy of the workpiece and reduces the service life of the tool. For general tool holders, when the ratio of length to diameter (L / D) exc...
