[0001] The utility model relates to the technical field of excavators, in particular to a welding tool for excavator body beams. Background Art

[0002] The excavator body beam is one of the components of the excavator frame assembly. It is mostly composed of two guide wheel plates and a bracket connecting the two guide wheel plates. The guide wheel plates are used to install guide wheels for installing crawler tracks, and the bracket not only connects and fixes the two guide wheel plates, but also supports the excavator's control panel.

[0003] During the manufacture of the excavator body beam, the bracket needs to be welded to the guide wheel plate. However, due to the large variety of excavator models, the sizes of the guide wheel plate and the bracket also vary. This also makes it difficult for the welding tooling to adapt to the splicing and welding operations of guide plates and brackets of different sizes. Moreover, the guide wheel plate is mostly welded to the bracket in a direction perpendicular to the base surface of the bracket. This also means that the guide wheel plate needs to be kept stable during welding to prevent the guide wheel plate from being dislocated or moved, which affects the overall forming effect of the excavator body beam. Summary of the Invention

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-Figure 4 A welding fixture for an excavator body beam comprises a base 1. Mounting holes are provided at the corners of the base 1. When in use, bolts can be taken through the mounting holes to fix the base 1 with bolts.

[0024] like Figure 1 and Figure 2 As shown, fixing parts are provided at both ends above the base 1, and the two sets of fixing parts are arranged opposite to each other, and slide rails 2 are installed on both sides of the top of the base 1, wherein the fixing parts are connected to the slide rails 2 through sliders, and connecting plates 13 are installed on both sides of the fixing parts, and locking bolts 14 are threadedly connected to the connecting plates 13. The ends of the locking bolts 14 correspond to the base 1, so that the two fixing parts can move relative to each other on the base 1, and after moving, the locking bolts 14 can be turned to make the locking bolts 14 rest on the base 1, so that the fixing parts can be firmly fixed on the base 1, so as to tighten the fixing parts after the position is adjusted.

[0025] like Figure 1 and Figure 4 As shown, each set of fixing members includes two parallel beams 3, which are arranged along the length direction of the slide rail 2, and the sliders are fixed to the bottom of the beams 3. There are at least two sliders at the bottom of each beam 3, and the sliders are fixed to the beams 3 at intervals, so that the beams 3 can be stably slidably installed on the slide rail 2. The connecting plate 13 is fixed to the side of the beam 3. The longitudinal beams 4 are provided at both ends above the beam 3. The ends of the longitudinal beam 4 are connected to the beam 3 through the connecting frame 5.

[0026] Two oppositely arranged splints 8 are provided at both ends between the two longitudinal beams 4, and a pushing mechanism 9 is vertically installed on the relatively distant side of the two splints 8. The pushing mechanism 9 is fixed to the longitudinal beam 4 through a mounting seat 10. In actual use, the pushing mechanism 9 is one of an electric push rod, a hydraulic cylinder, and an air cylinder. Under the operation of the pushing mechanism 9, the splint 8 can move in a straight line, so that after the guide wheel plate is placed between the two longitudinal beams 4, the splint 8 can be abutted against the guide wheel plate to clamp and fix the guide wheel plate; a buffer pad 11 is installed on the side of the splint 8 away from the pushing mechanism 9. The buffer pad 11 is an elastic rubber pad with a rough surface. It can be deformed after the splint 8 contacts the guide wheel plate and provide elastic force to the guide wheel plate. In addition, the roughness of the surface of the buffer pad 11 can further improve the fixing effect of the splint 8 and the guide wheel plate, and prevent the guide wheel plate from sliding between the splints 8.

[0027] Furthermore, a guide shaft 12 is provided parallel to the side of the pushing mechanism 9, one end of the guide shaft 12 is fixed on the splint 8, and the other end of the guide shaft 12 slides through the mounting seat 10, providing guidance for the movement of the splint 8, making the movement of the splint 8 more stable.

[0028] It should be noted that a support frame 6 is provided between the two cross beams 3, the end of the support frame 6 is connected to the cross beam 3, and a number of spaced support seats 7 are vertically installed on the top of the support frame 6; the support seat 7 is a columnar block, and a support platform is installed on the top of the support seat 7, and the surface area of ​​the support platform is larger than the top surface area of ​​the support seat 7. When the guide wheel plate is placed between the two longitudinal beams 4, the bottom of the guide wheel plate can be placed on the support seat 7, thereby providing upward support for the guide wheel plate, which not only ensures the stability of the guide wheel plate when it is fixed, but also allows the guide wheel plate to be raised and leave a gap between the base 1 to facilitate the installation of equipment on the guide wheel plate.

[0029] Specifically, when in use, first fix the base 1 on the support table, then take the guide wheel plate and place it in the two fixing parts for installation, then move the fixing parts to adjust the distance between the two guide wheel plates, and adjust it to the position corresponding to the bracket connecting the guide wheel plates, finally tighten the locking bolt 14, take the bracket and place it on the guide wheel plate to start welding.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
