【摘要】：車(chē)齒法是一種高效率高精度的齒輪加工工藝,相比傳統(tǒng)的滾齒、插齒加工工藝效率更高,且應(yīng)用范圍非常廣,特別是對(duì)于非貫通的螺旋內(nèi)齒輪加工,具有明顯的優(yōu)勢(shì)。車(chē)齒刀具作為車(chē)齒工藝中關(guān)鍵的組成部分,其設(shè)計(jì)方法的研究是推進(jìn)車(chē)齒工藝向前發(fā)展的最重要因素之一。鑒于此種情況,本文針對(duì)車(chē)齒工藝進(jìn)行了研究,提出了一種適用于車(chē)齒加工工藝的通用刀具結(jié)構(gòu)形式和刃形的設(shè)計(jì)方法,在此基礎(chǔ)上開(kāi)發(fā)了車(chē)齒刀CAD軟件,并通過(guò)VERICUT仿真軟件對(duì)所設(shè)計(jì)的車(chē)齒刀具進(jìn)行了驗(yàn)證。首先,本文基于空間交錯(cuò)軸齒輪嚙合原理,建立了車(chē)齒刀切削內(nèi)齒圓柱齒輪的數(shù)學(xué)模型;由曲面共軛原理,建立刀具與工件的嚙合方程,并與工件齒面方程聯(lián)立得到嚙合線方程;利用坐標(biāo)變換矩陣,得出了與工件齒面相嚙合的曲面,即刀具齒面的數(shù)學(xué)模型;然后選擇合適的前刀面與刀具齒面求交,所得的空間曲線即為車(chē)齒刀具的主刃刃形。其次,根據(jù)上述車(chē)齒刀具設(shè)計(jì)的理論基礎(chǔ),以Visual C++6.0為開(kāi)發(fā)工具,通過(guò)AutoCAD的二次開(kāi)發(fā)軟件工具Auto LISP,利用ODBC技術(shù),完成了車(chē)齒刀CAD軟件的開(kāi)發(fā)。本系統(tǒng)采用模塊化的軟件開(kāi)發(fā)原理,將系統(tǒng)分為參數(shù)輸入模塊、設(shè)計(jì)計(jì)算模塊、CAD繪圖模塊、數(shù)據(jù)庫(kù)管理模塊,通過(guò)這四大模塊之間的數(shù)據(jù)交換,最終輸出了車(chē)齒刀具的設(shè)計(jì)工程圖。最后,通過(guò)Pro/E構(gòu)建車(chē)齒機(jī)床和車(chē)齒刀具模型,并導(dǎo)入VERICUT軟件中完成車(chē)齒加工仿真實(shí)驗(yàn),利用軟件自帶的自動(dòng)對(duì)比功能得出仿真實(shí)驗(yàn)結(jié)果。通過(guò)分析仿真結(jié)果驗(yàn)證了該車(chē)齒刀具刃形設(shè)計(jì)方法的正確性,為進(jìn)一步對(duì)車(chē)齒工藝的研究提供了指導(dǎo)意義。
[Abstract]:Turning gear method is a kind of gear machining technology with high efficiency and high precision. Compared with traditional gear hobbing, gear shaper machining is more efficient and has a wide range of applications, especially for non-through spiral internal gear machining, which has obvious advantages. As a key part of the wheel gear process, the research of the design method is one of the most important factors to promote the development of the wheel tooth process. In view of this situation, this paper has carried on the research to the lathe tooth craft, has proposed one kind of general tool structure form and the blade shape design method which is suitable for the turning tooth processing technology, and has developed the lathe tooth cutter CAD software on the basis of this. The designed tool is verified by VERICUT simulation software. First of all, based on the meshing principle of spatial staggered shaft gears, the mathematical model of cutting inner cylindrical gears with wheel teeth cutter is established, and the meshing equation between cutting tool and workpiece is established according to the principle of surface conjugation. The meshing line equation is obtained with the tooth surface equation of the workpiece, the mathematical model of the surface meshing with the tooth surface of the workpiece is obtained by using the coordinate transformation matrix, and then the proper front cutter surface and the tooth surface of the cutter are selected to obtain the intersection. The space curve obtained is the main edge shape of the tool. Secondly, according to the theoretical basis of the design of the lathe tooth cutter, the development of the CAD software of the lathe tooth cutter is accomplished by using the ODBC technology, taking Visual C 6.0 as the development tool, through the secondary development software tool Auto list of AutoCAD. The system is divided into parameter input module, design and calculation module CAD drawing module, database management module, data exchange between the four modules, the system is divided into parameter input module, CAD drawing module and database management module. Finally, the design engineering drawing of the tool is output. Finally, the model of the lathe tooth machine tool and the lathe tooth tool is constructed by Pro/E, and the simulation experiment is completed in the VERICUT software, and the simulation results are obtained by using the automatic contrast function of the software. The correctness of the design method is verified by analyzing the simulation results, which provides guidance for the further study of the wheel tooth technology.
