中心孔打孔机的设计说明书

1、中心孔打孔机的设计说明书文档仅供参考湘潭大学兴湘学院专业课程设计说明书题目中心孔打孔机的设计专业机械设计制造及其自动化班级 机械6班学号 964406姓名 方海军指导教师陈睿完成日期年01月22日中心打孔机,包括机壳、电机座、电机导轨和两个压杆,所述机壳内 具有推块,机壳的顶部具有螺母，螺杆的一端经过螺母穿过机壳的顶部与 推块相连，电机导轨与机壳固定连接，电机座经过电机导轨与机壳滑动连 接，电机座内具有电机，电机的输出端连接有动力头;所述推块的下端具有 滚轮,推块的中部两侧对称开有向上的两个斜槽，每个压杆的一端装有导 向轮,导向轮在斜槽内滑动，每个压杆的中部经过回转销与机壳转动连接, 每个压杆

2、的另一端也均装有滚轮。本实用新型的中心打孔机，不但能快 速的夹紧工件，三点快速夹紧，自动定心，实现自动打中心孔的目的。中、长圆钢工件，加工时圆跳动大，一般须预先钻好中心孔后，再 用顶尖定位一端进行车削加工。本设计的目的在于设计一种专用的中 心孔钻孔设备，可方便地对圆钢工件进行中心孔钻孔操作。关键字：中心钻孔；中心定位；带传动；花键传动AbstractCenter punch, including chassis, motor, rail, and two compressive bar inside the casing has stated push block, the top of th
