Drilling machine structure with short stroke and high operating safety

Abstract

The invention discloses a drilling machine structure with short stroke and high operating safety. The drilling machine structure comprises a base, a workbench, a lifting rod, a lifting platform, an electric machine, a rotating shaft, a drilling bit, a lifting rocker and a power switch, wherein the workbench and the lifting rod are arranged on the base; the lifting platform is sleeved on the lifting rod; the electric machine is fixedly arranged on the lifting platform; the rotating shaft of the electric machine passes through the lifting platform; the drilling bit is fixedly arranged on the rotating shaft; the lifting rocker is also arranged on the lifting platform; the power switch is arranged at the head part of the lifting rocker. The drilling machine structure has the beneficial effects that safety is relatively high and energy sources are saved.

Description

technical field

[0001] The invention relates to the field of mechanical processing, in particular to a drilling machine structure with safe row height for short-stroke operation. Background technique

[0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes on a workpiece. Usually the drill bit rotates as 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 and blind holes, replace special tools, expand, countersink, ream or tap. According to different types, drilling machines can be divided into bench drilling machines, vertical drilling machines, radial drilling machines, milling drilling machines, deep hole drilling machines, etc.

[0003] The working principle of the drilling machine is also very simple. The motor drives the brick to rotate at a high speed, and the lifting rocker is rotated to ma...
