However, in actual use, when facing excavator front frame components of different sizes, since the first positioning assembly and the second positioning assembly are fixedly arranged on the supporting plate, it is impossible to adjust the corresponding clamping positioning position according to the excavator front frame components of different sizes, which is inconvenient for the staff to operate and use and the subsequent welding work of the excavator front frame components of different sizes, thereby easily narrowing the adaptability range of the entire device. Therefore, it is necessary to improve a welding fixture for excavator front frame components. Utility Model Content

At this time, since the fixing of the pressing frame 412 is released, the No. 1 spring 418 contracts, and then drives the support blocks 417 on both sides to move inward, so that the support blocks 417 is no longer in contact with the horizontal slot plate 3, and then the moving block 411 is pulled to move the moving block 411 along the guide in the slot of the horizontal slot plate 3, thereby driving the pressing mechanism 5 to move, and when it reaches the appropriate position, it stops, and then by pressing the pressing frame 412, the pressing frame 412 is completely inserted into the moving block 411, and at the same time, the pressing frame 412 drives the push rod 413 to move downward, so that the push rod 413 pushes the front and rear expansion rods 415 to move downward, so that during the downward movement of the expansion rod 415, the expansion rods 415 are respectively The connecting rods 414 on both sides are driven to rotate with the connection point of the moving block 411 as the axis, thereby driving the supporting blocks 417 on both sides to move outward, so that the supporting blocks 417 on both sides are again in contact with the inner wall of the horizontal groove plate 3, thereby completing its fixation. At the same time, when the pressing frame 412 moves downward, the inclined surface of the inclined block 421 contacts the pressing frame 412, thereby driving the inclined block 421 to move outward during the pressing process of the pressing frame 412. When the pressing frame 412 is completely reset, the inclined block 421 is re-locked under the elastic force of the No. 2 spring 423.

When the adjustment is completed, the clamping mechanism 5 is set, and the rotating handle 54 is rotated. The rotating handle 54 drives the screw 53 to rotate, and then the screw 53 drives the pressing plate 56 to move downward, so that the pressing plate 56 is guided downward along the sliding column 55 to press the welding parts to be welded.
