Material extravehicular exposure apparatus

The invention relates to a material extravehicular exposure apparatus. The apparatus comprises: a base; a test box detachably mounted on a locking and supporting mechanism; a rotary lifting device mounted in the middle of the base, connected with the locking and supporting mechanism and driving the locking and supporting mechanism to rotate and lift; a positioning device which is driven by the rotary lifting device to rotate and lift, can be elastically supported on the base and is used for detecting the position state of the rotary lifting device in the rotary lifting process; and an inspection mechanism installed on the base and capable of moving within a preset range in the circumferential direction of the base. The exposure device disclosed by the invention can provide extravehicular exposure resources for materials such as metal materials, non-metal materials, composite materials and the like, the on-orbit rapid replacement of a material exposure sample device is realized, closedprotection is provided fo
