Specific embodiment
The present invention is described in further detail below in conjunction with attached drawing embodiment.
As shown in Figures 1 to 5, which includes：
Pedestal 1, by pedestal 13 and the first end cap 14 and the second end cap 15 that are connected on 13 both sides of the face of pedestal.First end
Lid 14 connects pedestal 13 with the second end cap 15 by screw (not shown).
First end cap 14 is equipped with the intake tunnel 51 of connection cooling water source (not shown) and cooling-water duct 5；The
Two end caps 15 are equipped with connection cooling-water duct 5 and the out-of-bounds exhalant canal 52 of drainage arrangement (not shown).
The air cavity 2 of lateral direction penetrating is equipped in pedestal 13 along its length, the bottom surface of air cavity 2 is equipped with slot 21.
Length direction in pedestal 13 in the top of air cavity 2 along pedestal is equipped with longitudinally through stomata 3, and stomata 3 connects gas
Chamber 2 simultaneously exposes to pedestal upper surface.
Positioned at the outer surface of the both sides of stomata 3 respectively for the first supporting surface 11 and use of the first workpiece of positioning on pedestal
In the second supporting surface 12 of positioning second workpiece, the structure of the first supporting surface 11 and the second supporting surface 12 is mutually fitted with workpiece to be welded
Match somebody with somebody.The present embodiment is two orthogonal planes.
Multiple air admission holes 4 connected with air cavity 2, the present embodiment three are equipped at intervals on wall corresponding to first supporting surface 11
It is a；The axis of each air admission hole 4 is with respect to the horizontal plane into 30 °, and the outlet of air admission hole towards stomata 3, i.e., each air admission hole is by outer
