【摘要】：隨著科學技術(shù)的快速發(fā)展和市場競爭的日益激烈,企業(yè)的技術(shù)創(chuàng)新能力、新產(chǎn)品的開發(fā)能力和開發(fā)速度正成為企業(yè)核心競爭力的重要體現(xiàn)。低成本高效率地開發(fā)出新產(chǎn)品,成為贏得市場競爭的首要因素。 本文針對中小民營企業(yè)技術(shù)開發(fā)力量不足的現(xiàn)狀,以南通XX羅茨鼓風機有限公司新產(chǎn)品的開發(fā)為例,首先介紹了一種基于數(shù)控程序的產(chǎn)品反求設(shè)計方法。該方法分為：零件近似幾何圖形的獲取、高次曲線的反求和優(yōu)化設(shè)計三個階段。在此基礎(chǔ)上,以3L4系列羅茨風機轉(zhuǎn)子反求設(shè)計為例,詳細介紹了從數(shù)控程序到轉(zhuǎn)子近似幾何圖形的獲得、從圓弧擬合圖形到真實漸開線方程的生成以及轉(zhuǎn)子線型的最終優(yōu)化設(shè)計,為中小企業(yè)反求設(shè)計提供技術(shù)指導和支持；其次,提出了一種基于均半徑圓弧擬合和誤差抵消的轉(zhuǎn)子刨削加工方法。針對普通牛頭刨床刀架系統(tǒng)剛性不足的問題,提出采用誤差抵消的方法在數(shù)控程序中進行補償。以3L5系列羅茨風機轉(zhuǎn)子為例,詳細介紹了均半徑圓弧擬合轉(zhuǎn)子漸開線的過程；在此基礎(chǔ)上,對產(chǎn)生誤差區(qū)域進行局部偏移進行二次修正,以保證轉(zhuǎn)子最終加工精度；最后,開發(fā)了基于Solid works的羅茨風機參數(shù)化設(shè)計系統(tǒng),以便中小企業(yè)能夠進行系列化快速設(shè)計,滿足客戶的多樣化和快速需求。
[Abstract]:With the rapid development of science and technology and the increasingly fierce market competition, the technological innovation ability, new product development ability and development speed of enterprises are becoming an important embodiment of the core competitiveness of enterprises. Low-cost and high-efficiency development of new products has become the first factor to win market competition. In view of the lack of technical development power in small and medium-sized private enterprises, taking the new product development of Nantong XX Roots Blower Co., Ltd as an example, this paper first introduces a reverse design method of product based on numerical control program. The method can be divided into three stages: obtaining approximate geometry of parts, reverse seeking of high order curve and optimizing design. On this basis, taking the rotor reverse design of 3L4 series Roots fan as an example, the acquisition of approximate geometry from numerical control program to rotor is introduced in detail. From the arc fitting figure to the generation of real involute equation and the final optimal design of rotor profile, it provides technical guidance and support for the reverse design of small and medium-sized enterprises. In this paper, a rotor planing method based on mean radius arc fitting and error canceling is proposed. Aiming at the shortage of rigidity of the tool holder system of ordinary oxhead planer, an error offset method is proposed to compensate in numerical control program. Taking the rotor of 3L5 series Roots fan as an example, the process of fitting the involute of rotor with mean radius arc is introduced in detail, on the basis of which, the local offset of producing error region is modified twice to ensure the final machining accuracy of rotor. A parameterized design system for Roots fan based on Solid works is developed so that SMEs can carry out serial and rapid design to meet the diverse and rapid needs of customers.
