Profile processing device for passive aluminum alloy doors and windows

The invention discloses a passive aluminum alloy door and window profile machining device which comprises a profile body, a seat plate, a feeding mechanism, a cutting mechanism, a fixing seat, a clamping mechanism, a right-angle positioning chuck, a calibration mechanism and a spraying device. The head of the section bar body is positioned and fixed through the right-angle positioning chuck, the middle of the section bar body is fixed through the clamping mechanism, then the section bar is driven by the feeding mechanism to move from right to left, in the process, chamfering cutting machining is conducted through the cutting device, chamfering machining can be conducted on a plurality of section bar bodies at the same time, and machining efficiency is improved. The machining efficiency is improved, bending of a cutting line can be effectively avoided, the chamfering forming effect is improved, the cutting position of the profile body can be adjusted through the calibration device, machining of all profile bod
