The utility model discloses a positioning structure for machining a key groove of a broaching machine. Machining table, a loading block is welded to the middle of the bottom of the machining table. Abase is arranged on the upper surface of the loading block; a positioning cavity is formed in the bottom of the base; connecting plates are perpendicularly welded to the bottoms of the outer walls ofthe two sides of the base. Stand columns are perpendicularly welded to the edges of the two sides of the upper surface of the base. The two sets of stand columns are horizontally distributed. A welding groove is formed between the middle positions of the outer walls of the two sides of the stand column. An inner threaded sleeve is fixedly installed in the stand column through a welding groove, a first positioning block and a second positioning block are arranged on the upper surface of the base, the longitudinal section of the first positioning block and the longitudinal section of the secondpositioning block are both
