【摘要】：石油鉆井完井時需要用射孔槍打開油層,內(nèi)盲孔射孔槍具有良好的定向性和爆破效果。但由于射孔槍屬于深孔工件,在深孔內(nèi)壁處直接進(jìn)行盲孔加工較難實現(xiàn),通常會采用在工件外壁打通孔后進(jìn)行焊堵來得到盲孔,該方法加工的工件會出現(xiàn)焊接處強(qiáng)度不夠的問題。本文以深孔內(nèi)壁盲孔加工刀具為研究對象,以原有深孔內(nèi)壁盲孔加工系統(tǒng)為基礎(chǔ),通過對其進(jìn)行優(yōu)化設(shè)計,改善系統(tǒng)的加工性能�；诩庸は到y(tǒng)設(shè)計目標(biāo),改進(jìn)設(shè)計加工系統(tǒng)整體結(jié)構(gòu),通過對系統(tǒng)部分結(jié)構(gòu)進(jìn)行優(yōu)化,提高了系統(tǒng)的加工范圍。介紹了深孔內(nèi)壁盲孔加工刀具工作原理,并根據(jù)其原理,對刀具整體結(jié)構(gòu)進(jìn)行優(yōu)化設(shè)計。對刀具內(nèi)部傳動結(jié)構(gòu)進(jìn)行了改進(jìn),詳細(xì)設(shè)計了主運動傳動零件結(jié)構(gòu),并利用有限元分析,分析了該設(shè)計結(jié)構(gòu)的強(qiáng)度,同時運用運動仿真,探討了設(shè)計的主運動傳動副的合理性。進(jìn)行深孔內(nèi)壁盲孔加工試驗,研究了加工平臺的加工精度,并進(jìn)行深孔內(nèi)壁鍵槽銑削試驗,研究了加工刀具的工藝擴(kuò)展性。通過試驗,得到了較好的盲孔精度,并完成了鍵槽加工,為以后的刀具設(shè)計提供了新的思路。
[Abstract]:It is necessary to open the reservoir with perforating gun in oil drilling and completion. The perforating gun with inner blind hole has good directionality and blasting effect. However, because perforating gun belongs to deep hole workpiece, it is difficult to process blind hole directly at the inner wall of deep hole. The blind hole can be obtained by welding after the outer wall of the workpiece is plugged, and the workpiece machined by this method will have the problem of insufficient welding strength. In this paper, the deep hole inner blind hole machining tool is taken as the research object. Based on the original blind hole machining system of deep hole, by optimizing the design, the machining performance of the system is improved. Based on the design goal of the machining system, the whole structure of the machining system is improved, and the partial structure of the system is optimized. The working principle of the deep hole inner blind hole machining tool is introduced, and according to the principle, the overall structure of the tool is optimized, and the internal transmission structure of the tool is improved. The structure of the main moving transmission part is designed in detail, and the strength of the designed structure is analyzed by using finite element analysis. At the same time, the rationality of the designed main motion transmission pair is discussed by using the motion simulation, and the machining test of blind hole in the deep hole inner wall is carried out. The machining accuracy of the machining platform is studied, and the milling test of deep hole inner wall keyway is carried out, and the process expansibility of the machining tool is studied. Through the experiment, a better blind hole precision is obtained, and the keyway machining is completed. It provides a new idea for tool design in the future.
