Portable efficient drilling machine

Abstract

The invention discloses a portable efficient drilling machine. The drilling machine comprises a bottom plate; a motor box is fixedly connected in the middle of the top of the bottom plate; a motor mounting platform is fixedly connected at the bottom of the inner wall of the motor box; a first motor is fixedly connected at the top of the motor mounting platform; an output shaft of the first motor is fixedly connected with a first conical wheel; the first conical wheel is connected with a second conical wheel in a meshing manner; the second conical wheel is fixedly connected with a threaded shaft through a flat key; the outer wall of the threaded shaft is sleeved with a sliding block; and a fastening screw is arranged in the middle of one side of the sliding block. The invention relates to the technical field of engineering machinery. With the portable efficient drilling machine, the purpose that the drilling machine is adjustable vertically and horizontally, drill bits are replaceable, workpieces at different heights on a workbench can be perforated, and workpieces with relatively large horizontal sizes can be machined are achieved, the purpose of changing the bits quickly is achieved, the high working efficiency is guaranteed, light rays required during working can be supplemented, and the working quality can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a portable high-efficiency drilling machine. Background technique [0002] There are mainly two integral forms of the traditional drilling machine, the cast box column or the round steel tube column. The former is more common in large drilling machines, and the latter is more common in small vertical drills or bench drills, radial drills, etc. The columns of these two types of drilling machines are mostly vertical columns, and the worktable is slidably set on the column. This structure makes the working space narrow and the shape is relatively old. Holes, but not adjustable in the horizontal direction, it is difficult to process workpieces with large horizontal dimensions. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a portable high-efficiency drilling rig, which solves the problem that the drilli...
