Method for precisely locating laser beam space

The invention relates to a method for precisely locating a laser beam space, wherein at least one laser beam is incident to a first reflector; the first reflector reflects the laser beam to a second reflector; the second reflector reflects the reflected laser beam; therefore, the laser beam reflected by the second reflector passes through a tooling hole in a corresponding tooling set; the preciselocation of the laser beam is realized; the number of the laser beams is same as the number of the tooling sets; the tooling set comprises a first tooling and a second tooling; the hole centre of thefirst tooling and the hole centre of the second tooling are on the same straight line; and the straight line is vertical to the hole bottom surface of the first tooling.
