This utility model discloses a metal ring laser engraving machine, which includes a machine base and a worktable. The machine base is fixedly mounted with a mounting frame, on which a laser emitting device is slidably mounted. The worktable is located on the machine base and below the laser emitting device, and includes a tiltable mounting base and a turntable. The turntable is rotatably mounted on the tiltable mounting base, and has multiple placement slots spaced along its circumference. Each placement slot has a fixed positioning post, and an arc-shaped clamping plate slidably mounted on its inner sidewall, connected to the slot wall by a spring. The multiple placement slots on the turntable can simultaneously hold multiple metal rings. A first motor drives the turntable to rotate, causing the metal rings to sequentially enter the laser engraving area, eliminating the need for frequent loading and unloading and improving processing efficiency. The combination of positioning posts, arc-shaped clamping plates, and springs forms an adaptive clamping structure. The circumferential placement slots of the turntable and the motor drive design enable automated batch processing, further improving work efficiency.
