The invention discloses an electromagnetic equipment installation device and method. A box fixing assembly comprises third spur gears, fourth spur gears, second clamp bars, servo motors, second rotaryshafts, second mounting grooves, third rotary shafts, fixed blocks, supporting rods, eccentric wheels, reset springs, moving plates, moving grooves, insertion bars and clamping grooves. The corresponding two sides of the top of a base are both provided with the second mounting grooves. The servo motors are fixed to one sides of the bottoms of the second mounting grooves through bolts. Output shafts of the servo motors are connected with the corresponding third rotary shafts through couplings. The top ends of the third rotary shafts are sleeved with the third spur gears through keys correspondingly. The second rotary shafts are connected to the positions, located on one sides of the corresponding servo motors, of the bottoms of the corresponding second mounting grooves through bearings. The electromagnetic equipment installation device facilitates splicing and installation of a box, also facilitates integral installation and fixation of the box and is simple in structure and stable infixation.
