Machining device for door furniture axial central holes for civil defense

Abstract

The invention relates to the technical field of civil defense protection equipment and discloses a machining device for door furniture axial central holes for civil defense. The machining device includes a drill bit, a lifting rod is fixedly installed on the front surface of the drill bit, a supporting plate is fixedly connected to the portion, on the right side of the lifting rod, of the bottom of the drill bit, a worktable is fixedly connected to the portion, at the bottom of the drill bit, of the left side of the supporting plate, and a fixed clamping plate is fixedly connected to the portion, at the bottom of the drill bit, of the top of the worktable. According to the machining device for the door furniture axial central holes for civil defense, through arrangement of two triangular head anti-declination blocks, after a movable clamping plate and the fixed clamping plate are both in contact with an object to be machined, a turntable is still selected at that time, and the left ends of the triangular head anti-declination blocks can be clamped to the inner walls of anti-declination grooves. Since the two triangular head anti-declination blocks are symmetric and a left structureis triangular, the fixed clamping plate is relatively parallel to the movable clamping plate, and a problem that the axial central holes are eccentric since clamping is not stable is solved.

Description

technical field [0001] The invention relates to the technical field of civil defense protection equipment, in particular to a processing device for an axis hole of a civil defense door fitting. Background technique [0002] The civil air defense door is the door of the entrance and exit of the civil protection project. The classification of the civil air defense door is relatively clear. There are ordinary single, double-leaf protective airtight doors and airtight doors, living threshold single, double-leaf protective airtight doors and airtight doors and other civil air defense equipment. Civil air defense is also called Civil defense, civil defense is an international general term, it is the activities that the government mobilizes and organizes the masses, adopts anti-airstrike, disaster relief measures, implements rescue operations, and prevents and mitigates disasters. [0003] The emergence of civil air defense doors can guarantee our personal safety under special circ...
