I本科毕业设计论文题目自动防盗门开锁机构设计系别机电信息系专业机械设计制造及其自动化班级姓名学号指导教师2013年4月II自动防盗门开锁机构设计摘要随着社会物质则富的日益增长,安全防盗已成为社会热点问题自古以来锁就是把守门户的铁将军,是人们则富和安全的忠实守护神。现代社会,人们对防盗锁的要求越来越高,既要安全可靠,又要使用方便,这也是制锁者长期以来研制的主题。随着电子、机电与信息技术的应用,防盗锁已进入电子时代,原有的弹子锁由于结构上的局限已难以满足当前社会管理和防盗要求,本设计在机械锁的基础上加以改进,用机械手控制机械锁,实现开锁的目的机械手开锁机构锁保密好、使用方便,适用于多种用途,不仅增加了锁的种类,而且传统的制锁业能够应用电气、机电技术而获得新生。关键词机械手开锁机构机电技术IIDesignofautomaticantitheftdoorUnlockingmechanismAbstractWiththegrowingsocialandmaterialwealth,securityhasbecomeasthehotsocialissuessinceaccountedforsincethelockisguardedportalsofironwillThearmyisthepeople,richandsafefaithfulpatronsaint.Inmodernsociety,peopleTheantitheftlockoftheincreasinglyhighdemand,bothsafeandreliable,butalsoEasytouse,thisisthelockhavelongdevelopmenttheme.WiththeApplicationofelectronic,electricalandinformationtechnology,hasenteredtheelectricityantitheftlockAge,theoriginallockbecausethestructureoflimitationshasbeendifficulttofull.Thecurrentsocialmanagementandsecurityrequirements,thisdesignbasedonmechanicallock.Improvement,manipulatorcontrolmechanicallock,torealizetheunlockingpurposethelockmechanismofmanipulatorlockgoodsecurity,easytouse,suitableforavarietyofpurposes,notonlyincreasedthelocktype,butthetraditionalThelockcanbeusedelectrical,mechanicalandelectricaltechnologywasborn.KeywordmanipulatorUnlockingmechanismElectromechanicalTechnologyIII目录1绪论..............................................................................................................................11.1研究的目的和意义....................................................................................................12自动防盗门开锁机构的机械手设计.................................................................22.1开锁机构机械手整体的设计要求............................................................................22.2开锁机构机械手零件的基本要求及参数................................................................22.3本章小结....................................................................................................................33自动防盗门开锁机构的原理分析、方案确定及材料选择.......................43.1驱动方式....................................................................................................................43.1.1液压驱动.............................................................................................................43.1.2电机驱动.............................................................................................................43.2传动方式....................................................................................................................53.2.1带传动.................................................................................................................53.2.2链传动.................................................................................................................53.2.3齿轮传动.............................................................................................................63.2.4蜗杆传动.............................................................................................................63.3开锁机构机械手结构................................................................................................63.4材料选择....................................................................................................................83.4.1机械材料选用原则.............................................................................................83.4.2材料的工艺要求.................................................................................................93.4.3零部件材料选择要求.......................................................................................103.5本章小结..................................................................................................................114开锁机构的机械手计算......................................................................................124.1机械手零件尺寸及强度计算及校核......................................................................124.1.1开锁力的估算................................................................................................124.1.2机械手爪的受力分析.......................................................................................124.1.3丝杠的尺寸计算...............................................................................................134.2齿轮的选择及计算..................................................................................................134.2.1选定齿轮的类型、精度等级、材料及齿数...................................................134.2.2按齿面接触强度设计.......................................................................................144.2.3按齿根弯曲强度设计.......................................................................................15IV4.2.4几何尺寸计算...................................................................................................164.3本章小结..................................................................................................................175开锁机构机械手锥齿轮几何尺寸设计计算.................................................185.1大端模数..................................................................................................................185.2其他参数................
