Lifting type indoor drilling machine capable of automatically replacing drill bit

Abstract

The invention discloses a lifting type indoor drilling machine capable of automatically replacing a drill bit. The lifting type indoor drilling machine comprises a machine shell, wherein a lifting positioning cavity with an upward opening is formed in the right side of the machine shell, a replacement positioning mechanism for controlling lifting positioning during drilling and replacing the drill bit is arranged in the lifting positioning cavity, a positioning support is arranged in the lifting positioning cavity and slidably connected with the wall of the cavity, the upper end of the positioning support extends out of the cavity, and a lifting groove with a leftward opening is formed in the left end of the positioning support. Through the replacement positioning mechanism in the device, drill bit replacement can be automatically carried out if needed when a target material is changed during drilling, lifting positioning can be effectively carried out during drilling, high-position and low-position work can be completed, and thus it is avoided that workers climb up and down. Positioning drilling can be carried out after a drilling mechanism is automatically calibrated, it is further guaranteed that drilling work is smoothly completed, multiple tedious and dangerous work tasks become safe and automatically integrated, and thus the working quality and efficiency are ensured.

Description

technical field [0001] The invention relates to the field of drilling, in particular to a lifting type indoor drilling machine for automatically changing drill bits. Background technique [0002] At present, there are endless drilling equipment, and there are various drilling machines suitable for various drilling operations. They use tools that are harder and sharper than the target object through rotary cutting or rotary extrusion, Cylindrical holes or holes are left. [0003] However, most of them are hand-held by manpower. When they need to adapt to different heights, they need to make workers climb up and down, and it will be very difficult and unstable to position off the ground, and it is very dangerous. Apostasy, thus needing to replace the drill bit also needs to be replaced several times up and down, making the construction process very cumbersome. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a lif...

[0003] However, most of them are hand-held by manpower. When they need to adapt to different heights, they need to make workers climb up and down, and it will be very difficult and unstable to position off the ground, and it is very dangerous. As a result, it is necessary to replace the drill bit with it, and it needs to be replaced several times up and down, which makes the construction process very cumbersome
