Automatic guiding, locking and aligning device for precise instrument

The utility model discloses an automatic guiding, locking and aligning device for a precise instrument. The automatic guiding, locking and aligning device comprises a mounting plate (1), at least one locking mechanism (2) and at least one guiding mechanism (3), the locking mechanism (3) is arranged in the middle of each side of the mounting plate (1); and the guide mechanisms (3) are arranged at four corners of the mounting plate (1). Four groups of guide mechanisms (3) are arranged at four corners of the mounting plate, so that the whole device is effectively guided to stably lift in a narrow space, four groups of centrally arranged locking mechanisms (2) are used for locking and aligning, a loaded heavy object is effectively prevented from overturning and unbalance at a working position, spatial position alignment is automatically completed, and the problem that the working position is not influenced on the premise of no manual intervention is solved. The precise instrument is automatically guided to enter
