【摘要】：分别建立了刀倾型弧齿锥齿轮铣齿机和双转台五轴加工中心的运动学模型,进行运动转换求解时,选择原点和z轴分别与齿坯设计交叉点和齿坯轴线重合的坐标系作为描述运动的基础坐标系,调整两类机床的基础坐标系使其相对于各自的齿坯和刀盘分别具有相同的位姿,从而建立两类机床运动模型之间的联系.将刀盘相对于基础坐标系的位姿与齿坯相对于基础坐标系的转速分开求解,根据等效转化的原则求解五轴加工中心的各轴运动;根据挂轮滚比计算出产形轮与被切制齿轮的速比.实现了切齿运动由刀倾型弧齿锥齿轮铣齿机向五轴加工中心的实时转换,因而可以用五轴加工中心切制出与刀倾型弧齿锥齿轮铣齿机切制的齿型一致的齿轮,VERICUT切齿仿真得到的齿型证明了这一点.
[Abstract]:The kinematics models of the milling machine and the five-axis machining center of double-rotating table are established, and the kinematic transformation is carried out. The coordinate system, in which the origin and z axis coincide with the design point and axis of the billet respectively, is chosen as the basic coordinate system to describe the motion, and the basic coordinate system of the two kinds of machine tools is adjusted so that they have the same position and pose in relation to their respective billets and cutters, respectively. Thus the relationship between the two kinds of machine tool motion models is established. The position and orientation of the cutter head relative to the basic coordinate system and the rotation speed of the tooth blank relative to the basic coordinate system are solved separately, and each axis motion of the five-axis machining center is solved according to the principle of equivalent transformation. The speed ratio of the production gear and the cut gear is calculated according to the roll ratio of the hanging wheel. The real time conversion of tooth cutting motion from cutter tilting spiral bevel gear milling machine to five axis machining center has been realized. It is proved that the gear profile with the same profile as that made by the cutter tilting spiral bevel gear milling machine can be produced by the five-axis machining center cutting. The simulation results obtained by VERICUT have proved this point.
