Mutually parallel, nut is arranged in one end of strut, and nut is corresponding with bolt to be spirally connected, the level board of the lower section of a pair of bolts and a pair of of angle bar
Setting sealing hold-down mechanism between top；
The structure of the sealing hold-down mechanism are as follows: the upper surface of pair of horns molten iron plate is respectively provided with a pair of of bottom guard plate, bottom
The structure of portion's backplate is the integrally formed composition of sealing plate that inverted L-shaped is arranged in level board one end, the longitudinal direction of the sealing plate of the inverted L-shaped
Board bottom end is corresponding with one end of level board to be fixed, and is arranged on the upper surface of the bottom guard plate of the side of the sealing plate of inverted L-shaped solid
The round steel of cylindrical body, the diameter of round steel is consistent with the height of the inverted L-shaped sealing plate, the sealing plate of round steel and the inverted L-shaped it
Between gap in gasket is set, level board one end of bottom guard plate leaks out level board one end of angle bar, a pair of of bottom guard plate
It leaks out and is fixed between end by the way that bottom angle steel is corresponding, air inlet pipe is set in the cavity between bottom angle steel and a pair of of bottom guard plate；
Setting examination test plate (panel) between the bottom surface of a pair of bolts and the level board upper surface of inverted L-shaped sealing plate, examination test plate (panel) are logical
Cross bolt compression corresponding with the transverse plate upper surface of L shape sealing plate of bottom guard plate.
Working principle: welder qualification test test plate (panel) is placed in the upper surface of the transverse plate of the L-shaped sealing plate of bottom guard plate, so
After rotate bolt, by bolt will take an examination test plate (panel) it is corresponding with bottom guard plate compress, then using paper self-adhesive tape by examination test plate (panel) weld seam
Front is clung, by argon gas hose and air inlet pipe to connecting after, by air inlet pipe to examination test plate (panel) the following table second be filled with argon gas, so
Weld seam position adhesive tape to be welded is opened afterwards, feels there is cold air with the back of the hand, illustrates that argon gas has been substituted the bad for the good, adjusts argon flow
It is welded.
The utility model has the advantages that the utility model structure is simple, cost is relatively low, easy to operate, and chamber volume is small, back protecting effect
Preferably, argon gas is saved；And pass through repetition test, weld seam back shape effect is fine.
