The utility model discloses an automatic drilling device for a
guitar inner ring, which belongs to the technical field of
guitar production devices, and comprises a bottom frame, a plurality of supporting columns are fixedly connected to the top surface of the bottom frame, and a tray frame is fixedly connected among the top ends of the supporting columns; and the fixing
assembly comprises a main gear, a side gear, a movable
rotating disc, a plurality of movable columns, an upper
rotating disc and a plurality of movable parts, and the movable
rotating disc is rotationally connected to the top face of the tray frame. According to the automatic drilling device for the
guitar inner ring, the rotary air cylinder drives the upper rotary disc to rotate, the connecting rod drives the fixing plate to linearly move, and therefore the guitar inner ring is fixed, the drilling
machine punches the fixed guitar inner ring, the air cylinder retreats, the rotary motor drives the movable rotary disc to rotate, and the guitar inner ring rotates; and the positioning effect is better, meanwhile, the drilling efficiency is higher, and production operation is facilitated.
