Auxiliary positioning device of drilling machine

Relates to the technical field of drilling machine machining, and discloses a drilling machine auxiliary positioning device which comprises a base and a fixing column arranged at the top end of the base, a drilling machine is arranged on one side of the fixing column, telescopic assemblies are arranged on the two sides of the drilling machine, and pressing assemblies are arranged at the bottom ends of the telescopic assemblies. The pressing assembly comprises a pressing plate, a limiting plate is fixedly mounted in the pressing plate, and a plurality of pressing rods are arranged in the limiting plate; the door frame fixing device is simple in structure, when the extrusion rods make contact with the special-shaped end faces, the extrusion rods can move upwards, the pressing rings can be driven to compress the second springs, the different extrusion rods can independently stretch out and draw back at different depths, and therefore when the door frame with the conical or arch-shaped end face is encountered, th
