Advantage of the present utility model and good effect are:

1. welding effect is good, the quality height.Left and right pressure roller and the contact roller on the forward and backward compression beam in the utility model all can be pressed onto on the welded blank up or down, laser head is positioned at the working region scope that left and right pressure roller and contact roller surround, can guarantee gap and flatness between thin and thick two plates, realize the high quality welding effect.

2. the sheet material that is fit to different-thickness.The utility model respectively drives cylinder and all is connected with pressure valve, difference according to sheet metal thickness, can change the down force pressure of left and right pressure roller and contact roller by the high speed pressure valve, guarantee the flatness of sheet material, and make the gap between the soldered thin and thick sheet material reach minimum, satisfy the laser stitch welding requirement, and then avoid the harm that takes place because of the sheet material problems of welded quality.

3. working stability, reliable is simple in structure, easy to operate.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Wherein: 1 is laser head, 2 be Y to slide unit, 3 is right pressure roller, 4 is first to drive cylinder, 5 is mount pad, 6 is left pressure roller, and 7 is the second driving cylinder, and 8 is preceding compression beam, and 9 is the 3rd driving cylinder, 10 is the back compression beam, and 11 is the 4 wheel driven dynamic air cylinder, and 12 is welded blank, and 13 is contact roller.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figures 1 and 2, the utility model is installed on the portal frame, comprises that laser head 1, Y are to slide unit 2 and forward and backward compression beam 8,10.Forward and backward compression beam 8,10 can be arranged at the top of portal frame workbench up or down, lays respectively at the both sides, front and back of laser head 1.The two ends of preceding compression beam 8 are connected with its 3rd driving cylinder 9 that moves up and down of control, and the two ends of back compression beam 10 are connected with its 4 wheel driven dynamic air cylinder 11 that moves up and down of control.Be evenly equipped with a plurality of contact rollers 13 respectively on the forward and backward compression beam 8,10.Be installed in Y on the portal frame crossbeam to slide unit 2 between forward and backward compression beam 8,10, can be at Y to moving back and forth, Y is provided with the first driving cylinder 4 to a side of slide unit 2, its output is connected with and is installed on moving back and forth up and down of right pressure roller 3, the first driving cylinder 4 control right pressure rollers 3 of Y on slide unit 2.Y is provided with laser head 1 and mount pad 5 to the opposite side of slide unit 2, and mount pad 5 is provided with second and drives cylinder 7, and its output is connected with the left pressure roller 6, the second that is installed on the mount pad 5 and drives moving back and forth up and down of the cylinder 7 left pressure rollers 6 of control.Laser head 1 and left and right pressure roller 6,3 Y under the drive of slide unit 2 with its interlock.Laser head 1 between left and right pressure roller 6,3, X that can be in diagram to and Z to moving back and forth; The contact roller 13 of left and right pressure roller 6,3 and forward and backward both sides has surrounded the working region of laser head 1.
