Drilling machine capable of relieving dill bit damage

Abstract

The invention discloses a drilling machine capable of relieving dill bit damage. The drilling machine comprises a base; universal wheels are movably connected to the two sides of the bottom of the base through brackets; a vertical column is movably connected to the left side of the top of the base; a workbench is fixedly connected to the right side of the top of the base; the top of the workbench is provided with a clamping device; a rocker arm is fixedly connected to the top of the vertical column; a liquid box is fixedly connected to the left side of the top of the rocker arm; and a machine box is fixedly connected to the right side of the bottom of the rocker arm. According to the cooling liquid circulation drilling machine, cooling liquid self circulation arrangement is adopted, the situations of drill bit abrasion, scrap splashing and seizing up of a drill bit and a machined workpiece in the operation process are decreased, thus, damage to the drill bit is relieved, and the production efficiency is improved; and by arranging water blocking plates on the two sides of the top of the workbench, the effect that cooling liquid used in the machining process is effectively recycled is ensured, and pollution of the cooling liquid to an operation platform is avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a drilling machine for reducing drill bit damage. Background technique [0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes on a workpiece. Usually, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The drilling machine has a simple structure and relatively low machining accuracy. It can drill through holes, blind holes, and replace special tools. , can be expanded, countersinked, reamed or tapped. Due to the lack of use of coolant in the machining process of ordinary drilling machines, the drill bit wears a lot during the machining of the workpiece, and it is easy to make the drill bit and the machining The parts are stuck, causing the common occurrence of drill bit damage and reducing labor productivity. Contents of the invention [0003] The purpose of t...
