摘　　要：为解决缫丝过程中给茧机内存在无绪茧且靠人工抓取的问题,设计了一种给茧机无绪茧自动抓取装置。传动部分由减速电机通过两个传动路线将动力传送至给茧机和横移滑轨机构。详细分析了横移滑轨机构所包含的曲柄滑块机构和齿轮齿条直线差动增倍机构运动特性,通过计算确定最佳抓取节点。最后介绍了末端抓取机构,并规划抓取后放置无绪茧和装置复位的时间节拍。分析表明给茧机无绪茧自动抓取装置结构合理可行,研究结果为给茧机无绪茧的处理提供一种新思路。The cocoon and silk industry is not only traditional national industry,important livelihood industry and international competitive advantage industry,but also a cultural symbol of China's diplomacy as a major country.At present,the development of the cocoon and silk industry is facing great pressure,mainly from the industry's low profits,high labor costs,and strong mobility of silk reelers,which brings great pressure to enterprises.In recent years,with the continuous progress of science and technology,most manufacturing industries have improved production automation,reduced manual participation production costs and improved production efficiency.In the 21 st century,China has successively launched Feiyu 2000 Preferred,Feiyu 2000 New Era,and Feiyu 2008 Automatic Silk Reeling Machines.The degree of mechanization has been continuously improved,but thedegree of automation has been.The problem of grabbing cocoons without end in the supplier of correct end cocoons has not been solved effectively,which seriously affects the quality of raw silk.In order to solve the problem that there are cocoons without end in supplier of correct end cocoons during silk reeling and the cocoons without end are grabbed manually,an automatic grabbing device for cocoons without end in supplier of correct end cocoons is designed.The transmission part transmits the power to the supplier of correct end cocoons and the transverse sliding rail mechanism through two transmission routes by the deceleration motor.The motion characteristics of the slider-crank mechanism and the linear differential doubling mechanism of gear and rack contained in the transverse sliding rail mechanism are analyzed in detail.The quantitative relationship between them is analyzed and the equation of motion is listed.The equation of motion is a transcendental equation containing an unknown trigonometric function and cannot be solved by algebraic geometry.MATLAB programming is applied to determine the best grasping node.Finally,the end-grabbing mechanism is introduced,and
