继续教育学院 毕业论文 题目：X5032立式学生姓名： 赵海 学 号： 班 级: 专 业： 机电一体化 指导教师： 200 年 月 X5032立式铣床的数控化改造 摘 要 　 THE X5032 VERTICAL MILLING MACHINE NUMERICAL CONTROL TRANSFORMATION ABSTRACT 　　The aim would be to the characteristics of the X5032 milling machine, and to meet production, under the prerequisite of the milling machine to do as little change, use of numerical control system, realize the milling machine movement X, Y, Z axis control and any of the three coordinates the linkage of the three axis control, improve the machining precision of the milling machine and automatic level and complete the milling machine numerical control reform . 　　According to the principle of economy and the needs of the production, the overallscheme of the for the machine table: remove the X, Y, Z axis in the system. Will be sliding ball screw vice replacement for ball screw pair, and modified the reduction gear box, the reduction gear, step motor. The stepping motor the reduction gear drive the ball screw rotation, and through the ball screw nut pair worktable rotate. Drive First cutting force calculation, and then according to the size of the cutting force calculation ball screws strength, stiffness, coupled with the calculation efficiency checking the selected ball screw. Choose the right ball screw installation. After gear transmission mechanism design, according to the selected the step motor step distance Angle, pulse equivalent, combined with the formula to calculate the slowdown, than to choose the appropriate gear, according to the selected gear parameters calculated the gear rotating inertia, combine the inertia of a ball screw, calculate general inertia. The last of the torque and computing load and load of maximum torque, according to the maximum torque select match stepping motor.
