Drilling machine

Abstract

The invention discloses a drilling machine. The drilling machine comprises a driving device; a dust collection box is movably mounted at the bottom of one side of the driving device; one side of the driving device is also fixedly connected with a worktable; the worktable comprises a worktable body and a positioning block; one side of the top of the driving device is also fixedly connected with a motor bracket through a connecting plate; a servo motor is mounted inside the motor bracket; the bottom of the servo motor is movably connected with the top end of a rotating shaft; the top of the rotating shaft is also fixedly connected with a differential speed changer; the bottom end of the rotating shaft is fixedly connected with a drill bit component through a flange. The drilling machine is simple in structure and reasonable in design, and has the advantages of preventing damages of a drill bit by regulating the rotating shaft to drive the rotating speed of the drill bit component, collecting scraps generated during a drilling process, saving the labor, preventing influences caused to the work progress by deviation, caused by position offset, of a drilling position of a pre-drilled work piece, increasing the cutting speed of the drill bit and improving the work efficiency of the drilling machine.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a drilling rig. Background technique [0002] Drilling machine is a kind of drilling machine powered by electric energy. Drilling machine refers to the use of tools that are harder and sharper than the target object to leave a cylindrical hole or Hole machinery and equipment collectively. [0003] Most of the existing drilling rigs do not have a differential transmission, and the rotating speed of the drill bit cannot be adjusted according to the hardness of the object, which may cause damage to the drill bit; most of the existing drilling rigs use twist-shaped drill bits, which have slow cutting speed and difficult Low efficiency; most of the existing drilling rigs are not equipped with positioning devices, which can easily lead to deviations in the drilling positions, resulting in processing failures and affecting work efficiency; and most of the existing dril...

Problems solved by technology

[0003] Most of the existing drilling rigs do not have a differential transmission, and the rotating speed of the drill bit cannot be adjusted according to the hardness of the object, which may cause damage to the drill bit; most of the existing drilling rigs use twist-shaped drill bits, which have slow cutting speed and difficult Low efficiency; most of the existing drilling rigs are not equipped with positioning devices, which can easily lead to deviations in the drilling positions, resulting in processing failures and affecting work efficiency; and most of the existing drilling rigs are not equipped with dust collection boxes. The object being drilled will drop a lot of debris, and the cleaning work after the falling debris has brought a lot of trouble to people, so we propose a drilling rig
