Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a wheel excavator engine support welding tooling. Background Art

[0002] Wheel excavators are wheeled excavators with wheeled travel mechanisms, primarily used in agriculture, municipal engineering, and construction. Due to the complex structure of the engine support grille, welding is challenging and requires extremely strict tolerances. To improve product precision and ensure first-pass pass rates, the quality of the welding fixtures for the engine grille is particularly important. Welding fixtures refer to specialized tools or equipment used to secure and position the equipment to be welded.

[0003] For example, the prior art announcement number CN219900734U is a wheel excavator engine hood welding tool. This utility model replaces the traditional processing table with a steel frame, and the engine hood is supported by a support frame, so that the bottom of the engine hood can be exposed. At this time, the worker can lie flat on the pallet and use a welding gun to weld the welding parts at the bottom of the engine.

[0004] However, the above-mentioned prior art still has the following problems when in use: when the worker drills to the bottom of the engine to perform welding operations, since the body is lying flat, the operation is very inconvenient and also dangerous. Based on this, the utility model provides a wheel excavator engine support welding tool with adjustable welding position. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Refer to the instruction manual Figure 1-6 The present invention provides a wheel excavator engine support welding tool, comprising a fixed tool 1 and a support assembly 2 for supporting the wheel excavator engine air intake grille, the fixed tool 1 comprising a wheel excavator contact plate 101, a hatch contact plate 102 fixedly welded to the top of the wheel excavator contact plate 101, a form-position reinforcing rib 103 and a neutral plate support frame 104 fixedly welded to the top of the hatch contact plate 102, and one end of the neutral plate support frame 104 is arranged on the inner side of the form-position reinforcing rib 103, and a form-position reinforcing rib 105 fixedly welded to the rear end of the neutral plate support frame 104;

[0026] The support assembly 2 includes a mounting base 201, which is detachably fixed to the bottom of the wheel excavator contact plate 101. A rotating rod 202 is fixedly passed through the interior of the mounting base 201. Both ends of the rotating rod 202 are sleeved with support plates 203. A reduction motor 204 is fixed on one of the support plates 203. One end of the output shaft of the reduction motor 204 passes through the support plate 203 and is fixed to one end of the rotating rod 202. The reduction motor 204 is used to drive the mounting base 201 to rotate, which saves time and effort in use.

[0027] In addition, an electric flatbed trolley 3 is provided at the bottom of each of the two support plates 203. A groove 4 is provided on the top of the electric flatbed trolley 3. The bottom ends of the two support plates 203 are fixed to the inner wall of the bottom of the groove 4. The electric flatbed trolley 3 is used to support the two support seats, so as to facilitate the movement and transportation of the wheel excavator engine. A handrail 8 is fixed on the top of one side of the electric flatbed trolley 3. The handrail 8 is provided on the outside of the support plate 203 to facilitate the staff to manually push the electric flatbed trolley 3.

[0028] When in use, the staff first places the wheel excavator engine air intake grille to be welded on the fixed tooling 1. The fixed tooling 1 is composed of a hatch contact plate 102, a form-position reinforcement rib 103, a neutral plate support frame 104, an added form-position reinforcement rib 105 and a wheel excavator contact plate 101. After the wheel excavator engine air intake grille is fixed with bolts, it can be welded. During the welding process, the staff can also use the reduction motor 204 to drive the rotating rod 202 to rotate, and use the rotating rod 202 to drive the fixed tooling 1 and the wheel excavator engine air intake grille on the mounting seat 201 to rotate, and adjust the position of the wheel excavator engine air intake grille, so as to facilitate the staff to perform welding operations, with high safety, and meet the welding requirements of different positions of the wheel excavator engine air intake grille.

[0029] It is worth mentioning that, based on the three-dimensional model of the wheel excavator engine air intake grille support, the profiling process is used to simulate the design of the dimensions of the wheel excavator contact plate 101, the hatch contact plate 102, the form and position reinforcement ribs 103, the neutral plate support frame 104 and the added form and position reinforcement ribs 105, so as to accurately ensure the welding dimensions and flatness, verticality, position and other requirements of the components.

The wheel excavator contact plate 101, the hatch contact plate 102, the form and position reinforcement ribs 103, the neutral plate support frame 104 and the added form and position reinforcement ribs 105 are assembled and manufactured through the positioning slots and lines. After completion, the joints are welded using carbon dioxide gas shielded welding, and then the fixed tooling 1 is leveled and shaped to ensure that the overall size of the fixed tooling 1 is qualified and the deformation is reduced.

[0030] Refer to the instruction manual Figure 1-6, the inner wall of the two support plates 203 close to one side is provided with an arc-shaped sliding groove 5, and the two arc-shaped sliding grooves 5 are slidably provided with arc-shaped sliders 6, and the two arc-shaped sliders 6 are respectively fixed on both sides of the mounting seat 201.

[0031] Two arc-shaped openings 7 are formed on the outer walls of the two support plates 203 , and the two arc-shaped openings 7 are symmetrically distributed on the support plates 203 , which can reduce the strength of the support plates 203 .

[0032] By arranging arc-shaped sliders 6 on both sides of the mounting seat 201, the arc-shaped sliders 6 follow the mounting seat 201 to slide in the arc-shaped slide groove 5, thereby improving the stability of the mounting seat 201 when driving the wheel excavator engine air intake grille to rotate, and two openings are arranged on the two support plates 203, which can reduce the weight of the support plates 203 and facilitate the staff to observe between the two support plates 203.
