The utility model relates to a beam expander switching device and laser processing equipment. The beam expander switching device comprises a driving part, a turntable and a plurality of beam expanders with different beam expanding multiplying power. A plurality of mounting holes are formed in the turntable along the circumferential direction at intervals; each beam expander is correspondingly mounted in one mounting hole, and the number of the mounting holes is larger than that of the beam expanders, so that vacant hole sites are reserved on the turntable. When the beam expander with a certain multiplying power needs to be used, the turntable is driven by the driving piece to rotate by a corresponding angle, so that the light beam passes through the beam expander with the corresponding angle, and the laser beam is expanded. The distance between the laser adjusting lenses does not need to be opened and closed, and the use convenience of the beam expander switching device is improved. When the beam expander is
