【摘要】：行星架作為行星減速器的重要部件,它的質(zhì)量對行星減速器地運行有著決定性的作用。本文通過研究行星減速器的工作原理和行星架的基本結(jié)構(gòu),對行星架的加工工藝提出了數(shù)控化改進方案,并對行星架的加工裝備提出了優(yōu)化方案,同時對行星架的加工進行仿真分析和實際加工實驗,最終驗證了改進后的加工工藝和裝備的可行性。本文通過對國內(nèi)外行星架的結(jié)構(gòu)特點和加工方式進行分析,發(fā)現(xiàn)了行星架傳統(tǒng)加工工藝和裝備中存在的問題,并提出了相應(yīng)的優(yōu)化方案。根據(jù)數(shù)控機床的特點和行星架的結(jié)構(gòu)特點,本文發(fā)現(xiàn)了行星架傳統(tǒng)加工工藝的不足,論證了傳統(tǒng)加工工藝進行數(shù)控化改進的可行性,同時提出了行星架加工的優(yōu)化工藝,并對部分工藝進行數(shù)控化改進,從而縮短了行星架的加工工藝流程。針對傳統(tǒng)行星架加工裝備中的不足,本文提出了鏜刀、銑刀、輔具以及夾具地改進方案,通過與傳統(tǒng)加工裝備進行對比,論證了改進方案的可行性。本文建立了行星架的實體模型,對行星架上的孔、壓板槽、壓板槽上的底孔以及吊環(huán)孔的加工進行仿真,驗證了優(yōu)化方案的合理性。最后,采用傳統(tǒng)加工方法和優(yōu)化方案對行星架進行實際加工實驗,并對加工后的零件進行檢測,通過對比表明,采用優(yōu)化方案加工出的零件在各方面都優(yōu)于傳統(tǒng)方案加工出的零件,從而驗證了優(yōu)化方案的正確性。
[Abstract]:As an important part of planetary reducer, the mass of planetary rack plays a decisive role in the operation of planetary reducer. In this paper, by studying the working principle of planetary reducer and the basic structure of planetary frame, the improvement scheme of machining technology of planetary frame is put forward, and the optimization scheme of processing equipment of planetary frame is put forward. At the same time, the machining process of the planetary frame is simulated and tested, and the feasibility of the improved processing technology and equipment is finally verified. Based on the analysis of the structural characteristics and machining methods of the planetary frame at home and abroad, the problems existing in the traditional processing technology and equipment of the planetary frame are found, and the corresponding optimization scheme is put forward. According to the characteristics of CNC machine tools and the structural characteristics of planetary frames, this paper finds out the shortcomings of the traditional machining technology of planetary frames, proves the feasibility of improving the traditional machining technology by numerical control, and puts forward the optimization technology of planetary frame machining. Part of the process is improved by numerical control, which shortens the processing process of the planetary frame. In view of the shortcomings of the traditional planetary frame processing equipment, this paper puts forward the improvement scheme of boring cutter, milling cutter, accessory and fixture, and proves the feasibility of the improved scheme by comparing it with the traditional processing equipment. In this paper, the solid model of the planetary frame is established, and the machining of the holes in the planetary rack, the bottom hole in the pressure plate slot and the hole in the hanger ring are simulated, and the rationality of the optimization scheme is verified. Finally, the traditional machining method and optimization scheme are used to carry out practical machining experiments on the planetary frame, and the processed parts are tested, and the comparison shows that, The parts machined by the optimization scheme are superior to the parts manufactured by the traditional scheme in every aspect, which verifies the correctness of the optimized scheme.
