Woodworking Machinery High-speed Motorized Spindle Structure Design And Performance Analysis

As an advanced manufacturing technology of the 21st century. Processing technology of high speed machining. Has a very broad application prospects. Due to the advantages of high-speed machining machining technology. In the field of wood processing industry. Also has a very large applications. Its high speed,. Efficient performance can improve processing efficiency. Reduce machining cutting. Speed too low caused by a series of processing problems. Such as feed speed,. Tool break easily, and so on. The last couple of years. Due to domestic demand for furniture and decorative markets. Domestic wood engraving machine industry also help. Good opportunity gained rapid development. China engraving machine industry base in Shandong, Jinan, Shandong’s top priority is basically over 90% woodworking machine manufacturers gathered in Jinan.This topic based on this kind of background, carried on has used in the carpentry carving the engine bed the forced-air cooling high speed electricity main axle development and the performance analysis, and has carried on the finite element analysis, the confirmation design reliability. Is for the purpose of to carrying on the forced-air cooling high speed electricity main axle the design research and development to carry on the beneficial exploration.The topic main research content is as follows:(1) Pair of ceramic ball bearing structure and the computation correlation theories have conducted the research. As well as the hertz contact theory has carried on the analysis to the ceramic ball bearing union study. Has completed the bearing axial pre-tight and the rigidity relations computation analysis. Has provided the rationale to the following design calculation.(2) Right Electricity main axle Overall Structure Carried on Design。Has carried on the analysis to the electricity main axle heat source, designed new has dispersed the hot jacket. And has determined the electricity main axle coolant conditions design proposal according to the analysis result. Because the carpentry carves the engine bed regarding the sealing property request, passes through several kind of seal way characteristic to carry on the contrast, this plan has carried on the gas seal design to the electricity main axle seal structure, increased the seal reliability.(3) In order to confirm the electricity main axle the static rigidity, this plan has established the main axle three-dimensional model using the solidworks three dimensional software, and has carried on the static analysis using the finite element ANSYS software to the electricity main axle. Confirmed its static rigidity to satisfy the design request.(4) In order to confirm the electricity main axle the dynamically rigid characteristic, this plan has established the main axle three-dimensional model using the solidworks three dimensional software, and carried on using the finite element ANSYS software to the electricity main axle has traced condition the analysis. Confirmed its rigidity to satisfy the design request.
