Design And Performance Analysis Of High-speed Motorized Spindle For Woodworker

High speed carving and milling is one of main wood working styles. The main transmission system of CNC carving and milling machine for woodworking extensively uses motorized spindle. There are many special requirements for the spindle working on the wood. This paper introduces the development of woodworker spindle at home and abroad firstly, and then analyzes the special requirements for the motorized spindle based on the principle of the wood-working, especially the requirements on the heat dissipation, balancing, bearing lubrication and preload control of the spindle. At last, discusses the main questions and measures on the design of the motorized spindle.First of all text versus woodworker with high-speed motorized spindle proceed oversee detailing, avail PROE erect carpentry with high-speed motorized spindle three-dimensional analysis model, adopt finite-element analysis law versus high-speed motorized spindle activity state characteristic proceed oversee analytical study for of.Concretion content includes:1. through the medium of flush joint compose Design middle some main technical problems (as bearing electrotype, dynamic balance Design, geometric accuracy Design, spindle modular construction parameter static state estimate wait) solution of decide, finish design woodworker with high-speed motorized spindle physical .2. versus high-speed motorized spindle cell standard technological procedure parameter down spindle station suffer cutting resistance, main shaft bearing static rigidity, spindle cell primary structure parameter and high-speed motorized spindle cell critical speed isoparametric proceed oversee static state estimate.3.both versus high-speed motorized spindle proceed three-dimensional static state and dynamic finite element modeling, by ansys, derive oversee motorized spindle static rigidity.
