Laser quenching device for wear hardening treatment of drill pipe thread surface

Abstract

This utility model belongs to the field of drill pipe processing equipment application technology, and particularly relates to a laser quenching device for wear-resistant hardening treatment of drill pipe thread surfaces. It includes a frame and a laser generator mounted on the frame. The laser generator is connected to a laser beam assembly. A drill pipe clamping and rotating mechanism is mounted on the frame, with the mechanism located near one end of the frame. A drill pipe support frame is also mounted on the frame to support the drill pipe. This utility model addresses the need for laser quenching of drill pipes of different lengths by using a drill pipe clamping and rotating mechanism at one end of the frame, allowing the drill pipe to be rotatably mounted on the frame and slidably mounted on the drill pipe support frame using a sliding seat. This allows for laser quenching of drill pipes of different diameters by using a lifting frame, and the use of a rotary motor to tilt the laser beam assembly at an angle to meet the needs of internal thread drill pipes, thus solving the laser quenching requirements of various types of existing drill pipes.
