摘要针对圆柱的孔进行专用钻机的设计与建模，通过电机高速旋转，带动钻头，实现旋转运动，将电机安装在安装座上，气缸推动安装座，这样就可以实现直线运动，因为是通孔，因此气缸行程只要满足大于孔的最大深度即可，因此需要设计专用夹具进行夹持。本文设计利用气缸带动 V 型块对圆柱零件进行定位夹紧，结构简单易操作，本文重点对电机、气缸以及夹具进行分别计算与设计，包括电机的功率与选型、气缸的缸径与行程的计算、夹具的夹紧与定位等，然后对该钻孔机进行建模与装配，完成专用钻孔机的设计。关键词： 专用钻机；高速电机；气缸；三维建模IABSTRACTDesign and modeling dedicated rig for cylindrical bore, high-speed rotary motor, drive the drill to achieve rotational movement, the motor is mounted on the mount, pushing the cylinder mount, so you can achieve linear motion, because it is a through hole, Therefore, as long as the cylinder stroke is greater than the maximum depth of the hole can be, and therefore need to design special jig holding. This design driven by an air cylinder V-block clamp is positioned on cylindrical parts, simple structure, easy to operate, this article focuses on the motor, cylinder and fixture calculate and design, including the calculation and selection of electrical power, the cylinder bore and stroke etc., clamping fixture and positioning, and the drilling machine modeling and assembly, to complete special drilling machine design.
