The invention discloses an electric vehicle-mounted air conditioner compressor production and machining auxiliary device. The device comprises a bottom plate, fixing plates, a fixing frame, a bar-shaped groove, limit sleeves, screws, first nuts, second nuts, an electric push rod, a panel, an air pump, an air pipe, an air inflation shell, first mounting holes, second mounting holes, slide blocks and slide grooves. The electric vehicle-mounted air conditioner compressor production and machining auxiliary device is reasonable in structure, when an air conditioner compressor is perforated, a drillrod used for perforation can be positioned through the limit sleeves, perforating operation of working staff is convenient and fast, the labor intensity of the working staff is relieved, and the perforating time of the working staff is shortened; through the screws, the first nuts and the second nuts, the positions of the limit sleeves in the fixing frame can be changed, and the device is suitable for various perforation hole locations; and during perforating, assistance can be provided for perforation through the electric push rod, the labor intensity of the working staff is relived, after perforation, chippings produced during perforation can be blown off through the air pump, the air pipe and the air inflation shell, and the working staff do not need to sweep and clean a clamp mountedon the panel.
