最近，中国的694一个标准高某型植物航天发展锁定钛螺栓，航天和航空系统评估组，由专家组成的评估过程中采用。这表明，植物持续3许多高钛合金年锁螺栓研制任务取得圆满成功，使高钛螺钉锁定了取得重大突破。

高锁螺栓和高锁螺母，其中包括高锁螺纹连接副具有重量轻，体积小，防松强，抗疲劳性能和装配效率高的特点可以实现单电机面紧缩行动在航天领域有广泛的用途。由于形状复杂，机械性能和更严格的要求和其他因素，钛高锁螺栓的发展结构是非常困难的。国外为了打破高科技制造业行业垄断和封锁锁紧固件，改善中国的标准水平，生产过程，工厂在2004年初开始了694的高钛紧固件锁定的审判工作。

三年，科学研究和技术人员作出不懈努力解决的技术问题一起路，克服技术上的一道道障碍，完成了高钛锁螺栓研究确定{dy}批试验任务，性能指标全部符合要求。这一问题的顺利发展，填补了国内高锁紧固件制造业的空白，打破了高锁紧固件垄断领域的国外厂商，以实现高锁紧固件的全面本地化的工作奠定了坚实的基础。

High-titanium alloy bolt lock made a breakthrough

Recently, China’s space development of 694 plants of a certain type of standard high-locked titanium bolts, adopted by the aerospace and aeronautical systems evaluation group composed of experts of the assessment process. This indicates that the plant lasted 3 years of many high-titanium alloy locking bolt mission to develop a complete success, so that the high titanium bolt lock made a major breakthrough was achieved.

high and high lock bolt lock nut, which comprises high-locked with thread connection Deputy light weight, small volume, anti-song strong, anti-fatigue performance and high efficiency characteristics of the assembly can realize a single-motor face tightening operation in the field of aerospace has a wide range of functions. Due to the structure of complex shape, mechanical properties and more stringent requirements and other factors, titanium locking bolts of the development of high-it is very difficult. Abroad in order to break the lock fasteners for high-technology manufacturing sector monopolies and blockade, improve China’s standard level of the manufacturing process, plant early in 2004 began a 694 high titanium fasteners lock the work of the trial.

3 years, scientific research and technical personnel make unremitting efforts to resolve the technical problems together Road, overcome the technical barriers to join Road to complete the first batch of high-titanium locking bolts research task identified tests, the performance index All meet the requirement. The successful development of the subject to fill the domestic high-lock fasteners manufacturing gap, breaking the foreign manufacturers in the field of high-lock fasteners monopoly, in order to realize high-lock fasteners comprehensive localization has laid a solid foundation .
