Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0012] Referring to Figure (1), a high-precision circuit board drilling positioning device includes a positioning module 1, a positioning groove 11 for placing the circuit board is opened on the top of the positioning module 1, and a plurality of limit grooves 12 are opened on the bottom of the positioning module 1. The limit grooves 12 are connected to the positioning grooves 11 through drilling grooves 13. A lifting plate 3 is arranged below the positioning module 1, and a drilling rig 2 is installed on the top of the lifting plate 3. The body of the drilling rig 2 can be extended into the limit groove 12 and is slidably connected with the limit groove 12. The drill bit 21 of the drilling rig 2 is slidably connected with the drilling groove 13. A pressing plate 4 is arranged above the positioning module 1, and the top of the pressing plate 4 and the bottom of the lifting plate 3 are respectively connected to the telescopic ends of the second telescopic machine 41 and the first telescopic machine 31.
