【摘要】：不銹鋼電水壺的應(yīng)用市場越來越大,對電水壺拋光質(zhì)量的要求也越來越高。為了保證水壺壺嘴焊接處的加工質(zhì)量,文章對壺嘴焊接曲面處的拋光路徑進(jìn)行了規(guī)劃。為了便于電水壺壺嘴的數(shù)控加工,首先對電水壺進(jìn)行實體掃描,建立水壺模型后可以有效提取磨具的刀觸點集,得到磨具的刀位點軌跡。并對磨具進(jìn)行拋光行距分析以及磨具姿態(tài)的控制分析,得到磨具任意加工點處刀軸轉(zhuǎn)動角度公式。最后在磨具刀位點軌跡以及姿態(tài)分析的基礎(chǔ)上對電水壺回嘴焊接曲面的拋光加工做運動仿真分析,加工時磨具加工面與壺嘴焊接曲面充分相切接觸,在很大程度上可以提高加工效率和加工質(zhì)量。
[Abstract]:The application market of the stainless steel electric kettle is becoming more and more large, and the quality of the electric kettle polishing is becoming more and more demanding. In order to ensure the processing quality of the welding place of the pot mouth, the polishing path of the surface of the pot mouth is planned. In order to facilitate the NC machining of the kettle mouth, the solid scans of the electric kettle and the water kettle are set up first. After the model, the tool contact set of the grinding tool can be effectively extracted and the tool locus of the grinding tool is obtained. The grinding distance analysis of the grinding tool and the control analysis of the grinding tool attitude are analyzed. The rotation angle formula of the cutter shaft at any machining point at the grinding tool is obtained. Finally, the welding surface of the electric kettle is reopened on the basis of the locus of the tool loci and the attitude analysis of the grinding tool. The polishing process makes motion simulation analysis. The machining surface of the grinding tool is in full contact with the curved surface of the pot mouth, and the processing efficiency and quality can be improved to a great extent.
