Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Embodiment of the present invention: adopt the present invention, a numerically controlled cutting tool system that utilizes microscopic friction and mass distribution to provide shock absorption. The inner and outer walls of the member 7 expand and deform. The expansion and deformation of the inner wall of the hydraulic fastener 7 squeezes the powerful spring 6, thereby forming the clamping and fixing of the knife bar structure. The pressure of the hydraulic grease 13 is indicated by the hydraulic gauge 8, and a suitable hydraulic grease pressure is selected according to different cutting forces.

[0023] The strong spring 6 is made up of several thin-walled parts, and the thin-walled parts assembly joint surface 11 is formed between several thin-walled parts. By adjusting the expansion deformation of the inner wall of the hydraulic ...

Abstract

The invention discloses a clamp and tool bar system for providing the vibration reduction performance of a numerical control tool by utilizing a microcosmic friction phenomenon in combination with a modal coupling method for mass distribution and mass vibration reduction of the numerical control tool under the premise that macroscopic assembly sliding is not caused. By regulating forward pressure, static rigidity, a vibration reduction coefficient and dynamic rigidity on each assembly combination surface, the vibration reduction performance of an overall tool structure is optimized. A tool bar structural member 4 is made from a material with high elastic coefficient and high density ratio, and a tool bar connecting piece 5 is made from a material with high elastic coefficient, so that the vibration modal frequency and the vibration reduction efficiency are improved. By utilizing modal coupling, the vibration reduction performance of a mass vibration reduction unit is further improved, and the torsional vibration resistance and the bending vibration resistance of the tool are improved. According to the technical solution, by virtue of a modular tool bar, the ratio of extended length to diameter in a using process of the numerical control tool can be improved, and the vibration reduction performance of a tool structure is improved.

Description

Technical field: [0001] The invention relates to a fixture and tool holder system for improving the shock-absorbing performance of CNC tools by using microscopic friction phenomena and mass distribution methods, which belongs to the manufacture of CNC tool tool holders for turning, milling, drilling, grinding, etc., and the clamping parts of CNC tools In the field of manufacturing technology, but not limited to the use on machining tools. The main purpose is to improve the dynamic stiffness of the mechanical structure by adjusting the microscopic friction phenomenon and mass distribution, thereby suppressing the vibration phenomenon during the machining process. technical background: [0002] During the use of CNC turning tools, the chattering phenomenon of the tool will be caused by the low shock absorption performance of the tool mechanical structure. Traditional cutting tools do not have a design for shock absorption, so the ratio of overhang length to diameter is usuall...
