辽宁科技大学本科生毕业设计（论文）第I页镶片式齿轮滚刀结构设计摘要本文对滚刀结构、工作原理进行分析。设计的基本思路是：在刀体上开出容屑槽，槽的一面和刀片的底部各有一定角度的斜面。在热处理后，刀槽与刀片的精度较高均需磨削过，然后把刀片压入刀槽内，再压入楔片紧固，并在滚刀的两头磨出刀片和刀体共有两个圆柱形凸肩，再把压紧环加热到一定温度，套到凸肩上去，压紧环冷却后，孔径减小，因而紧紧地把刀片压在刀体上，然后再用螺栓把压紧环紧压在刀体的端面上。对于滚刀的测量装置，设计的测量滚刀的齿形误差，检测装置的横向和纵向运动的实现，采用步进电机驱动丝杠，带动工作台运动；检测装置精度的保证，采用斜轨道来测量夹角；被测滚刀分度精度，采用脉冲电机保证分度精度。关键词：滚刀、测量装置、设计、工艺制造辽宁科技大学本科生毕业设计（论文）第II页ImbeddedgearhobdesignABSTRACTThispapercarriesontheanalysistothestructure,workingprincipleofhob.Thebasicideais:onthecutterbodyopengroove,bevelgrooveononesideandthebottomofthebladeisinacertainangle.Afterheattreatment,theknifegroovecontactwiththebladegrindingarerequired,andthenpressedintotheknifebladegroove,ispressedintothewedgefastening,andthetwohobgrindingbladeandcutterbodyconsistsoftwocylindricalconvexshoulder,theclampringisheatedtoacertaintemperature,toshoulderthepressingringup,aftercooling,theporesizedecreases,sotightlytothebladeontheknifebody,andthenusethebolttothepressingringispressedontheendsurfaceoftheknifebody.Forthemeasurementofgearhobs,toothprofileerrormeasurementofhobdesign,torealizethedetectiondeviceofthehorizontalandverticalmotion,usingthesteppermotortodrivethescrew,drivetheworkbenchmovement;ensurethedetectiondevicetomeasureprecision,Tomeasuretheinclinedorbitangleinclinedorbit;themeasuredhobindexingaccuracy,usingpulsemotorindexingaccuracy.KeyWords:ManufacturingHob,MeasuringDevice,Design,Process辽宁科技大学本科生毕业设计（论文）第III页目录1绪论................................................................................................................11.1选题背景及目的..............................................................................................................11.2滚刀技术的发展..............................................................................................................11.3课题研究方法..................................................................................................................21.4课题研究内容..................................................................................................................22滚刀分析........................................................................................................32.1齿轮滚刀优缺点..............................................................................................................32.2齿轮滚刀的工作原理......................................................................................................32.3齿轮滚刀的结构形式......................................................................................................42.4对齿轮滚刀的几何形状要求..........................................................................................52.5滚刀的最小长度应满足三个要求..................................................................................52.6滚刀计算长度还需要进行修正......................................................................................63齿轮滚刀的结构设计与计算.........................................................................73.1设计参数..........................................................................................................................73.2齿轮滚刀结构设计与计算..............................................................................................73.2.1齿形部分设计与计算................................................................................................73.2.2刀体部分设计............................................................................................................93.2.3刀片部分设计..........................................................................................................123.2.4楔片设计..................................................................................................................134齿轮滚刀刀体制造........................................................................................144.1刀体毛坯的选择............................................................................................................144.1.1毛坯尺寸确定..........................................................................................................144.1.2刀体余量部分..........................................................................................................154.2刀体机械加工工艺规程拟定........................................................................................164.3刀体加工工序分析........................................................................................................175齿轮滚刀检验标准........................................................................................365.1齿轮滚刀的检验标准....................................................................................................36辽宁科技大学本科生毕业设计（论文）第IV页6检测装置的设计............................................................................................376.1检测装置总体方案设计................................................................................................376.1.1系统运动方式确定..................................................................................................376.1.2伺服系统的选择......................................................................................................376.1.3执行机构的确定..................................................
