Description

Technical Field

[0001] The utility model relates to a welding tool, in particular to an adjustable welding workpiece clamping frame. Background Art

[0002] During welder on-the-job training and examinations, welders need to perform all-position welding according to the corresponding rules and frequently adjust the welding position and angle of the weld. The previous practice was to make temporary simple brackets for adjustment. The disadvantage is that multiple brackets need to be made, which wastes resources. In addition, they need to be replaced many times during the application process, which is time-consuming and labor-intensive. At the same time, they are often restricted by the site and their own posture, and many welding processes in special positions cannot be performed. Utility Model Content

[0005] The upright column is made of a stud, and the sleeve is fixed by two upper and lower lock nuts.

[0006] The cross section of the cantilever guide rail is in the shape of an I, and the slider is fixed to the cantilever guide rail by using a fastening bolt I.

[0007] The cantilevered horizontal support rod is provided with a plurality of pin holes evenly arranged along its length direction, and the lower end of the diagonal support rod is connected to the cantilevered horizontal support rod by using a pin.

[0008] The upper end of the clamping claw is provided with a jaw, and a fastening bolt II is provided on one side of the jaw.

[0009] The advantages and positive effects of the present invention are as follows: the height of the weldment can be adjusted by adjusting the height of the sleeve, the deflection angle of the weldment can be adjusted by adjusting the deflection angle of the cantilever guide rail, the horizontal distance between the weldment and the column can be adjusted by adjusting the position of the slider, and the inclination angle of the diagonal support rod can be adjusted by adjusting the position of the lower end of the diagonal support rod, thereby adjusting the inclination angle of the clamping claw and the welding angle. In summary, the application of the present invention can easily and quickly realize flexible adjustment of different welding positions, and even adjust to special angles, ensuring that all-position welding can be performed, which is very suitable for professional on-the-job training and examinations for welders.
