半自动钻床设计

摘要

台式钻床的简称为台钻，现已普遍于零件加工，以及机械修理的应用。但是此类的缺陷在于需要手动进给，非常影响生产效率。根据现有的台钻的基础上，来增加两个装置来激发此类钻床的潜力。一是自动进给装置能够做出“快速进给，工作进给，快速退回，停留”的动作，二是在主轴上安装多轴装置来提升产能。从而也可以降低劳动者的工作强度，降低成本。

本文首先介绍了台式钻床的国内外发展情况。其次根据课题需要，确定了此钻床的基本构造。选择电机传动为主要驱动机构，通过带轮传动和凸轮传动带动旋转。对凸轮辊进行了设计计算和校核，然后对带轮传动、齿轮传动进行了部分计算和校核。

Abstract

The drilling machine is referred to as bench drill, has generally to the parts processing, and the application of mechanical repair. But this kind of defect is the need for manual feeding, greatly affected the production efficiency. Based on the existing bench drill, to increase two to stimulate the potential of drilling device. One is the automatic feeding device can make rapid feed, feed, quick return, stay "in action, two multi axis device is mounted on the spindle to improve productivity. It can also reduce the work intensity of workers, reduce the cost.

This paper firstly introduces the development situation of the drilling machine at home and abroad. Secondly, according to the need of the subject, the basic structure of this drilling machine. Select the drive motor is the main drive mechanism, rotate by the belt wheel transmission and cam drive. The cam roller is designed and calculated and checked, and then the calculation and check of the belt drive, gear drive.

Keywords: bench drilling machine，automatically feed ，porous drilling
