A high precision electric drill

Abstract

The invention relates to a high precision electric drill which comprises a main body and a drill bit, wherein the drill bit is arranged horizontally; the drill bit is mounted on one side of the main body; a control mechanism is arranged on the main body; the main body is internally provided with a cooling mechanism; the control mechanism comprises a movement component and two limiting components;the movement component comprises a movement plate, a movement ring, a measurement ruler and two connecting units; the connecting units comprise polished rods, springs and support blocks; the cooling mechanism comprises a power component and a cooling component; the cooling component comprises a nozzle, a connecting pipe, a connecting box and an extrusion plate; and the nozzle is arranged above thedrill bit. According to the high precision electric drill, the machining precision is improved by the control mechanism; and in addition, a cooling effect is further achieved by the cooling mechanism.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to an electric drill with high precision. Background technique [0002] Electric tools are tools that generate driving force through electric energy and are convenient for users to complete tasks such as processing or assembly. Among them, electric drills are a type of electric tools, and electric drills are drilling tools that use electricity as power. They are the most demanded electric tool products. , which is mainly used for punching holes. [0003] When the existing electric drill drills a non-through hole, the depth of the hole cannot be accurately controlled, which greatly reduces the accuracy of the workpiece processing. Not only that, but when the electric drill is running, due to the rapid rotation of the drill bit, the temperature of the drill bit will rise sharply. When the temperature of the drill bit is too high, built-up edge is formed, which not only aggravates the we...

[0003] When the existing electric drill drills a non-through hole, the depth of the hole cannot be accurately controlled, which greatly reduces the accuracy of the workpiece processing. Not only that, when the electric drill is running, due to the rapid rotation of the drill bit, the temperature of the drill bit will rise sharply. When the temperature of the drill bit is too high, built-up edge is formed, which not only increases the wear of the drill bit, but also greatly reduces the service life
