Structural representation when Fig. 2 is 0 ° of angle of two blocks of plates to be welded of the present utility model.
Structural representation when Fig. 3 is 90 ° of angles of two blocks of plates to be welded of the present utility model.
Fig. 4 is the connection diagram between locating piece of the present utility model and the base recess.
Among the figure, the 1st, pedestal 2 is locating pieces; The 3rd, dog screw 4 is that material 5 to be welded is materials to be welded; The 6th, laser welding system 11 is horizontal parts the 12, the 13rd, and vertical component effect 14 is that groove 15 is that caulking groove 22 is holding screws.
The specific embodiment
As shown in Figure 1 and Figure 4, these anchor clamps mainly contain Qian shape pedestal 1, two "-" shape locating pieces 2 and dog screws 3.Pedestal 1 comprises horizontal part 11 and vertical component effect 12 and 13, respectively has groove 14 on horizontal part 11 and vertical component effect 12,13, and the cross section of groove is trapezoidal.On vertical component effect 13, have caulking groove 15.Locating piece 2 its screws are connected with holding screw 22, are fixed in (see figure 4) in two grooves 14 of pedestal 1, and these locating piece 2 width are wideer than the groove of pedestal 1, and tested inclination material 4 to be welded is placed between two locating pieces 2.Locating piece 2 can have magnetic, on magnetic absorption pedestal 1.Dog screw 3 is positioned over pedestal vertical component effect 13 caulking grooves 15 tops, and the screw thread of dog screw 3 matches with the screwed hole of pedestal caulking groove 15, and level material 5 to be welded is positioned pedestal caulking groove 15 places.
As shown in Figure 2, when carrying out 0 ° of space angle laser weld of two kinds of materials to be welded, material 4 to be welded is placed on the level material 5 to be welded, level material 5 to be welded uses dog screw 3 to be located in pedestal 1 vertical component effect 13 caulking grooves 15 places.Material 4 to be welded uses the locating piece 2 on pedestal 1 vertical component effect 12 to position, locating piece 2 be positioned over material 4 to be welded below, material to be welded 4 is supported, and holding screw 22 (not shown)s are fixed on groove 14 place's (see figure 4)s on the pedestal vertical component effect 12 with locating piece 2.
As shown in Figure 3, when carrying out 90 ° of angle laser weld, at first use dog screw 3 to be located level material 5 to be welded in pedestal 1 vertical component effect 13 caulking grooves 15 places, then with the snap mutually of material 4 to be welded and level material 5 to be welded, two locating pieces 2 are placed on respectively above horizontal part 11 grooves 14 of pedestal 1 of material to be welded 4 both sides, and fixing by the holding screw 22 of locating piece 2, to support material 4 to be welded.
When the position of the angle that changes material 4 to be welded and material to be welded 5 between 0 °～90 °, can be realized by regulating two positions of locating piece 2 on pedestal 1:
When 0 °～45 ° angle orientation of test, at first use dog screw 3 to be located level material 5 to be welded in pedestal caulking groove 15 places.Two locating pieces 2 are placed on (see figure 1) on two vertical component effects 12 and 13 of pedestal 1 respectively, wherein the locating piece 2 on the vertical component effect 12 places material to be welded 4 tops, locating piece 2 on the vertical component effect 13 places material to be welded 4 bottoms, holding screw 22 is fixed on two locating pieces 2 groove 14 places of pedestal vertical component effect 12 and 13 respectively, and the material 4 to be welded that will tilt is fixed.When changing the angle of tilt material 4 to be welded and level material 5 to be welded, only need distinguish the position of running fix piece 2, thereby realize the angular transformation between material 4 to be welded and the level material 5 to be welded.
When 45 °～90 ° dimensional orientations of test, at first use dog screw 3 to be located level material 5 to be welded in pedestal caulking groove 15 places.Two locating pieces 2 are placed on respectively on the vertical component effect 12 and horizontal part 11 of pedestal 1, and wherein the locating piece 2 on the vertical component effect 12 places material to be welded 4 tops, and the locating piece 2 on the level 13 places the side of material 4 to be welded near pedestal 1 vertical component effects 13.The holding screw 22 of two locating pieces 2 is fixed on locating piece 2 groove 14 places of pedestal vertical component effect 12 and horizontal part 11 respectively, and the material 4 to be welded that will tilt is fixed.When changing the angle of tilt material 4 to be welded and level material 5 to be welded, only need distinguish the position of running fix piece 2, realize the angular transformation between material 4 to be welded and the level material 5 to be welded.
When laser weld was carried out to test material in the two kinds of different angles of material to be welded orientation, laser welding system 6 can put on the binding site of material 4 to be welded and 5, thereby can carry out the laser welding process experiment of two blocks of materials to be welded of different angles.
