A radial drilling machine for air defense doors

Abstract

The invention relates to a radial drilling machine for civil air defense doors, which includes a bottom plate, a connecting plate is vertically fixed near the side of the bottom plate, a top plate is fixed horizontally to the top of the connecting plate, and the top plate is vertically arranged on the side facing the ground There is a fixed shaft, and a rocker arm is connected with rotation on the fixed shaft. A slide rail is provided on the rocker arm, and a punching mechanism is slidably connected to the slide rail. The sliding assembly that moves; the punching mechanism includes a shell that is slidably connected with the slide rail, and a chute that cooperates with the slide rail to slide is provided on the side wall of the shell, and a drive motor is arranged in the shell, and a For the drill bit, the drilling mechanism is also provided with a lifting assembly for driving the drill bit to lift, and the bottom of the fixed shaft is also provided with a drilling platform for carrying the drilling material. The invention has the effect of improving the working range of the drilling machine and further drilling large raw materials.

Description

technical field [0001] The invention relates to the technical field of drilling machines, in particular to a radial drilling machine for air defense doors. Background technique [0002] Civil air defense door, as the name implies, is the door used for the entrance and exit of people's protection works. When the civil air defense door is processed, the door panel needs to be punched. [0003] Such as figure 1 As shown, the existing radial drilling machine includes a base 6, a column 61 is vertically fixed on the base 6, and a working arm 62 is rotatably connected to the column 61, and the working arm 62 is arranged horizontally. Hole mechanism 63. The drilling mechanism 63 includes a drilling motor 64 and a drill bit 35 . The base 6 is also provided with a workbench 65 for drilling the plate 5 below the drill bit 35 . When the staff is using the radial drilling machine, at first the raw material to be drilled is placed on the workbench 65, then the working arm 62 is rota...

AI Technical Summary

Problems solved by technology

[0004] However, in actual use, the working range of the existing radial drilling machine is only the fan-shaped area where the front working arm 62 of the drilling machine body can rotate, and because the column 61 is erected on one side, the central angle of the fan-shaped area is less than 180 degrees

And the door panel of civil air defense door is generally bigger, and when the staff is punching four corners of civil air defense door, need to frequently adjust the position of civil air defense door on workbench 65, thus caused inconvenience
