Description

Technical Field

[0001] The invention relates to the field of laser welding, in particular to a welding fixture for flat plate butt laser welding. Background Art

[0002] In the scientific research experiment of flat plate butt welding, in order to ensure the welding quality, it is usually necessary to keep the two planes at the same level and clamp them. However, in the actual welding working condition, due to the uneven ground, the welding fixture will also tilt as a whole, which will cause a large assembly error, especially when the weldment itself is very thin, the slight unevenness will seriously affect the welding accuracy and welding quality. In order to solve this problem, the present invention provides a new technical solution to solve the current technical defects. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a welding fixture for laser butt welding of flat plates.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a welding fixture for flat plate butt laser welding, comprising a support column, a support plate, a lower pressure plate, a first movable bolt, and a second movable bolt, wherein the two support plates are located above the six support columns, the upper and lower end surfaces of the support column have threaded holes, the support plate is also provided with two through holes, and the six first movable bolts are located below the six support columns and connected through the threaded holes. The lower pressure plate is located above the support plate, and the second movable bolt is located above the lower pressure plate.

[0005] Furthermore, the first movable bolt and the second movable bolt have the same size, and the corners on the same side of the lower pressure plate are provided with arc cutouts, and the arc cutouts have the same size as the threaded hole and the through hole.

[0006] Furthermore, an anti-skid pad is provided on the end surface of the first movable bolt, and a scale is provided on the surface of the lower pressure plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] See also Figure 1 In an embodiment of the present invention, a welding fixture for flat plate butt laser welding includes a support column 1, a support plate 2, a lower pressing plate 3, a first movable bolt 4, and a second movable bolt 5. The two support plates 2 are located above the six support columns 1. The upper and lower end surfaces of the support column 1 are provided with threaded holes 6. The support plate 2 is also provided with two through holes 7. The six first movable bolts 4 are located below the six support columns 1 and connected through the threaded holes 6. The welding plate is placed on the support plate 2, and then the lower pressing plate 3 is placed on the welding plate. The second movable bolt 5 passes through the support plate 2 and the lower pressing plate 3 and is connected to the threaded hole 6 inside the support column 1. The second movable bolt 5 is rotated to clamp.

[0012] The first movable bolt 4 and the second movable bolt 5 have the same size. The corners on the same side of the lower pressing plate 3 are provided with a circular arc notch 7. The circular arc notch 7 has the same size as the threaded hole (6) and the through hole (7). The end surface of the first movable bolt 4 is provided with an anti-slip pad 8, and the surface of the lower pressing plate 3 is provided with a scale 9. The height of the support column 1 is adjusted by rotating the six first movable bolts 4, so that the two plates for butt welding are further in the same horizontal plane.
