AUTOMATIC EMBOSSING DRILLING MACHINE Mechanical Project

概要

钻孔是通过使用称为钻头的旋转刀具在工件上产生孔的过程。用于钻孔的机器称为钻孔机。通过钻孔机孔进行钻孔。

市场上有两种类型的钻床，用于进行钻井操作。

INTRODUCTION

We desired a drilling machine which will automatically index the job and gives automatic feed to the drill head. This machine is designed to perform drilling. Even though this is designed to drill a hole on circumference of a job, this can also perform a number of similar operations like drilling, remaining, boring, counter boring, counter sinking, tapping etc with slight alterations on the machine. We designed a drilling machine which uses only mechanical principles. Therefore it is very easy for maintenance and which improves the reliability of the machine.

该机器用于制造纺织工业中的雌性模具的主要目的。

工作准则

在三个子标题下解释了本机的操作原理。

1.驱动机制

2.饲料机制

3.索引机制

AUTOMATIC EMBOSSING DRILLING MACHINE Mechanical Project

1.驱动机制：

在驱动机构中，单相AC电动机用于驱动整个机器。虽然电机的速度较少，但它可以携带更多的负载。电机的电源为0.75汞量。通过链和链轮机构将电动机的旋转运动传递到齿轮箱中的蜗轮。车轮与蜗轮对齐，传动运动。

2.联合国机制：

齿轮内部的一侧连接到曲柄盘。曲柄盘的主要功能是将旋转运动转换为线性垂直运动以获得钻孔头的垂直进料。杠杆中的连杆机构连接曲柄盘和手钻机。它有助于将垂直进给传递到手钻机。

3. INDEXING MECHANISM:

从借助于连杆机构的帮助，动作被传递到爪子-1的连接臂。棘爪的运动是这样的一种方式，即它将在每个革命中推动两颗棘轮1的齿。之后，棘爪将回来并重复该过程。

索引作业的旋转运动：

棘轮-1的一侧连接到三个正齿轮，以减小速度，并且作业将根据棘轮的移动而旋转。因此，准确地诱导棘轮的旋转运动。

索引作业的水平运动：

One small rod is connected parallel to ratchet-1. One rod is also placed perpendicular to the ratchet-1 in such a way that after each revolution of rod 1 with respect to the ratchet wheel; it should strike on rod 1. Rod 2 is connected to one spring arrangement so that is should comeback to the initial position after the rod 1 get struck rod 2 once. As rod 2 moves up due to the striking of rod 1. This will cause the pawl 2 to push one tooth of ratchet-2, which is connected, to rack and pinion, which will cause it to push one teeth of the rack and pinion. Rack and pinion is connected to the horizontal slide and it moves. Hence after each revolution of Job one horizontal motion will be there.
