Tooling clamping plate positioning hole drill jig

The utility model belongs to the machining technology, and relates to a drill jig for machining an aircraft assembly tooling clamping plate positioning hole. The tooling clamping plate positioning hole drill jig is characterized by being composed of a drill plate (1), a pin (2), a positioning pin (3) and a jig bushing (4). A pin installation hole (1a), a positioning pin installation hole (1b) and a jig bushing installation hole are formed in the drill plate (1), the center distance between the pin installation hole (1a) and the positioning pin installation hole (1b) is equal to the center distance between a first bushing (6) on a tooling clamping plate (5) and a second bushing (7) on the tooling clamping plate (5), and the center distance between the positioning pin installation hole (1b) and the jig bushing installation hole is equal to the center distance between the second bushing (7) on the tooling clamping plate (5) and a positioning hole (8) to be drilled . The tooling clamping plate positioning hole drill jig has the advantages of being time-saving, labor-saving and unnecessary to disassemble the tooling clamping plate and a positioning piece on the tooling clamping plate, greatly improving production efficiency and reducing production cost.
