【摘要】:密封環(huán)是機械領(lǐng)域應用廣泛的一種零件,幾乎在每一臺機械設備上都有密封環(huán)的存在。本文需要研究的渦輪增壓器密封環(huán)是渦輪增壓器中重要的零部件之一,它存在于增壓器的渦輪端和壓氣機端,主要作用是封氣和封油,其質(zhì)量好壞直接影響到渦輪增壓器的使用壽命。 本文研究的密封環(huán)是在常溫常壓下進行加工的,其工作條件是高溫高壓,其技術(shù)要求的提出也是建立在受壓縮的高溫高壓的情況下。因此如何保證密封環(huán)符合技術(shù)要求就成了一件比較困難的事情。目前國內(nèi)增壓器密封環(huán)的生產(chǎn)工藝比較陳舊,生產(chǎn)成品率普遍不高。以某企業(yè)生產(chǎn)情況為例,密封環(huán)的成品率只有80%左右,剩下的次品報廢或者進行人工修磨,費時費力且人工修磨的成功率也并不高。 本文重點分析密封環(huán)裝配到增壓器后的側(cè)向間隙和開口間隙,討論對上述兩種間隙有影響的因素,進而對現(xiàn)有的加工工藝進行了改進,能夠使密封環(huán)的加工成品率有一定的提升。 為檢驗加工后的密封環(huán)是否符合技術(shù)要求,并能快速分揀出成品、可修磨品和廢品,本文利用CCD測量技術(shù)的原理,設計出了一套在自然狀態(tài)下密封環(huán)開口最小值的自動檢測方案,能夠自動測量出自然狀態(tài)下密封環(huán)的最小開口值。 盡管密封環(huán)的成品率有一定提高,但為了進一步減小報廢率,本文提出了一套對可修磨開口的密封環(huán)修口的專用機床總體方案,代替原先的人工修磨,從而提高生產(chǎn)效率、降低加工成本。 本文的創(chuàng)新之處在于: (1)優(yōu)化了現(xiàn)有的密封環(huán)加工工藝。 (2)設計出自動檢測密封環(huán)開口最小值的方案,自動快速分揀出成品、可修磨品和廢品。 (3)提出密封環(huán)修口專機總體方案,能夠進一步提高密封環(huán)的成品率。 本論文的研究內(nèi)容對國內(nèi)現(xiàn)有的密封環(huán)生產(chǎn)現(xiàn)狀具有實用價值,具有較強的可應用性。
[Abstract]:Sealing ring is one of the most widely used parts in the field of machinery and almost exists on every mechanical equipment. The seal ring of turbocharger is one of the important parts of turbocharger in this paper. It exists at the turbine and compressor end of the turbocharger, and its main function is to seal the gas and seal the oil. The quality of the turbocharger has a direct impact on the service life of the turbocharger. The sealing ring studied in this paper is processed under normal temperature and pressure, and its working conditions are high temperature and high pressure. The technical requirements are also based on the compression of high temperature and high pressure. Therefore, how to ensure that the seal ring meets the technical requirements has become a more difficult matter. At present, the production process ratio of the domestic turbocharger seal ring. Older. The production rate is generally not high. Take the production situation of a certain enterprise as an example, the finished product rate of the seal ring is only about 80%, and the remaining defective products are scrapped or manually milled. It takes time and effort and the success rate of manual grinding is not high. This paper focuses on the analysis of the side clearance and opening clearance after the seal ring is assembled to the supercharger, discusses the factors that affect the above two clearance, and then improves the existing processing technology. It can improve the finished product rate of seal ring. In order to verify whether the seal ring after processing meets the technical requirements and can quickly sort out finished products, repairable grinding products and waste products, the principle of CCD measurement technology is used in this paper. An automatic detection scheme for the minimum opening of the seal ring in natural state is designed, which can automatically measure the minimum opening value of the seal ring in the natural state. Although the finished product rate of the seal ring has been improved, in order to further reduce the scrap rate, this paper puts forward a set of special machine tool for repairing the seal ring with repairable opening instead of the original manual grinding. In order to improve production efficiency and reduce processing costs. The innovations of this paper are: The existing process of sealing ring is optimized. The scheme of automatic detecting the minimum value of seal ring opening is designed, and the finished product, repairable grinding product and waste product are sorted out automatically and quickly. 3) the overall scheme of seal ring repair machine is put forward, which can further improve the finished product rate of seal ring. The research content of this paper has practical value and strong applicability to the present production situation of seal ring in China.
