介绍了机床夹具设计中圆偏心夹紧机构的运动规律和实用设计方法,为企业夹具设计人员提供了偏心夹紧机构设计的新思路,从理论研究角度有效分析推算出偏心夹紧机构可靠性的自锁条件及最大偏心楔角的一般公式。大大提高了偏心夹紧机构设计的效率,缩短了新型偏心夹具的开发周期,提高了夹具设计的质量。为该产品的预评价、生产加工提供了重要依据。
This paper introduces the movement rule and practical design method of circular eccentric clamping mechanism in the design of machine tool fixture, provides a new idea for the design of eccentric clamp mechanism for enterprise fixture designers, and effectively analyzes and deduces the reliability of eccentric clamping mechanism from the theoretical research point of view Self-locking conditions and the maximum eccentric wedge angle of the general formula. Greatly improve the efficiency of the eccentric clamping mechanism design, shorten the development cycle of new eccentric fixture, improve the quality of fixture design. For the pre-evaluation of the product, production and processing provides an important basis.
