Support frame for additive manufacturing device

The utility model relates to the field of additive manufacturing, in particular to a supporting frame for an additive manufacturing device, which comprises a placing plate, supporting legs are fixed on two sides of the bottom of the placing plate, a bearing plate is arranged on the right side of the top of the placing plate, and a first electric push rod is fixed on the right side of the bottom of the placing plate. The first electric push rod can drive the bearing plate to ascend and descend, so that the position can be adjusted, meanwhile, the first high-precision distance sensor is matched, position information of the bearing plate can be effectively fed back, accurate adjustment can be achieved, meanwhile, equipment is placed in the groove, the clamping plate is driven by the second electric push rod to conduct clamping, and the clamping efficiency is improved. And a second high-precision distance sensor can feed back the position of a limiting plate, the position of the limiting plate is adjusted accordi
