Non-magnetic drill collar boring device

The invention provides a non-magnetic drill collar boring device, and belongs to the technical field of boring devices. The device comprises an operation platform, a mounting frame and a non-magnetic drill collar, a speed reduction driving mechanism is arranged above the mounting frame, a lifting mechanism for controlling the speed reduction driving mechanism to ascend and descend is arranged at the lower end of the mounting frame, and a clamping mechanism for clamping the non-magnetic drill collar is arranged on the upper side wall of the operation platform. A branch noise reduction assembly; the screw is driven by the double-shaft motor, the boring diameter can be adjusted according to the boring requirement, when the extending distance of the boring cutter is increased, the connecting rod can pull the limiting baffle to move to enlarge the opening of the liquid outlet end, and the cooling liquid flow can be automatically adjusted to meet the cooling and lubricating requirements of boring holes of different
