概述了在新机试制过程中，大量采用储备工装标准件和组合夹具是缩短新机试制周期，节约设计工时、制造工时，提高经济效益的重要途径；介绍了开展储备工装标准化工作的做法；列举了采用储备工装，用组合夹具替代专用夹具所带来的经济效果；提出了拓宽储备工装的应用领域，扩大组合工艺装备范围等设想。 In the process of trial production of new machine, a large amount of use of reserve tooling standard parts and combination fixtures is an important way to shorten the trial period of new machine, save the design man-hours, manufacture man-hours and increase the economic benefits. The paper also introduces the practice of standardizing reserve tooling. The use of a stocking tool, the use of combination fixtures to replace the special fixture brought about by the economic effect; put forward to broaden the application areas of the reserve tooling, to expand the scope of the combination of technology and equipment ideas.
