Variable-frequency control drill machine

Abstract

The invention relates to the drilling machine field and discloses a frequency conversion and speed regulation drilling machine which comprises a motor and a mainshaft; the drilling machine also comprises a frequency conversion and speed regulation system; the frequency conversion and speed regulation system is connected with the motor; the rotation speed of the motor is adjusted by adjusting the frequency of AC which is used for supplying the power for the motor; the drilling machine can precisely adjust the rotation speed of the motor only by rotating a knob when adopting the frequency conversion and speed regulation system; furthermore, the rotation speed is smoothly transitional, the operation is extremely simple and convenient, the time for speed regulation by workers is greatly reduced, and the working efficiency is improved further.

Description

A frequency conversion speed regulation drilling machine technical field The invention relates to the field of drilling machines, in particular to a variable frequency speed regulating drilling machine. Background technique Drilling machines are widely used in people's lives, especially in recent years with the development of industrial modernization and the improvement of people's living standards, factories, enterprises and even ordinary families will use them. The drilling machine has also developed from the initial simple function to the current complex operation requirements suitable for people's various processing requirements. But as the core of the drilling machine, the transmission transmission system is still a belt transmission, or a slightly advanced mechanical transmission. These variable speed systems have many disadvantages, resulting in complicated operation and reduced efficiency. It is increasingly unable to adapt to the faster and faster pace of life o...

Problems solved by technology

The most common speed change method for drilling machines at home and abroad is belt speed change, which can only realize point-to-point speed change, but cannot achieve smooth transition, and every time the speed change needs to be opened with a tool to adjust the belt, it is time-consuming and laborious, which is very troublesome

Some can achieve a relatively smooth mechanical speed change effect through the tension and speed regulation of two pulleys, but the requirements for the belt are high, and the mechanical pressure regulation is not accurate, the operation is inconvenient, and it cannot adapt to the flexible and changeable needs of modern society. , causing great inconvenience to users
