Middle plate machining drilling device

The utility model discloses a drilling device for machining a middle plate, which comprises a mounting base used for mounting all parts. According to the drilling device for middle plate machining, through mutual cooperation of the mounting base, the mounting plate, the drilling mechanism, the clamping mechanism, the cleaning mechanism and the supporting legs, after drilling is completed, a clamping motor rotates reversely to enable a clamping frame to be loosened, a cleaning motor rotates to drive a cleaning threaded rod to rotate, a connecting block moves rightwards, and a T-shaped push plate pushes a middle plate out of the clamping frame; chippings on the surface of the middle plate are cleaned through a brush frame, the chippings leak into a lower mounting base through a mounting plate, meanwhile, in the right moving process of a connecting block, the chippings on the inner wall of the scraper mounting base are scraped and finally pushed into a collecting box, the chippings are collected in a centralized
