The utility model relates to the technical field of
laser carving code scanning machines, in particular to a positioning device for a
laser carving code scanning
machine, which mainly comprises a supporting plate, a rotating adjusting frame is mounted in the middle of the top end of the supporting plate, a
rotating disc is mounted at the top end of the rotating adjusting frame, a carrier is arranged at the top end of the
rotating disc, and a guide positioning
assembly comprises a
butt joint frame. A protection plate is arranged on the inner side of the butt-joint frame, the end of the protection plate is connected with an extending plate, the positioning adjusting
assembly comprises a butt-joint clamping plate, and a moving plate is arranged on the inner side of the butt-joint clamping plate. According to the positioning device for the
laser etching code scanning
machine, when the
machining position of a carrier is adjusted through rotation of the
rotating disc, the extending plate on the outer side is pushed inwards and clamped to the inner side of the positioning clamping groove, the inserting edge is provided with a
radian, guiding input of the extending plate is facilitated, the rotating position of the rotating disc can be accurately controlled after inserting, and the
machining precision of the carrier is improved. And deviation is avoided, the
machining accuracy of the equipment is improved, and the product quality is ensured.
