Description

Technical Field

[0001] The utility model relates to the technical field of loader oil tanks, in particular to a welding tool for a loader oil tank. Background Art

[0002] The loader fuel tank is an important part of the loader. The fuel tank body is mainly welded by the rear sealing plate, the outer side plate and the rear side plate. It is used to store fuel. Its material is usually strong and durable, and can withstand various environmental influences. It plays a key role in the stable operation and safety of the loader.

[0003] In the prior art, the current assembly and welding of loader oil tanks mainly relies on manual marking and positioning of templates. Manual marking can easily lead to errors between products, resulting in poor product consistency. The assembly gap cannot be guaranteed to be consistent, which in turn affects the quality of the oil tank welds. For some oil tanks with larger assembly gaps, the formed welds will cause gaps in the weld parts due to errors, resulting in poor air tightness of the loader oil tank. When the welded oil tank is tested for air tightness, it will be found that there are unclosed gaps in the oil tank. The staff who have unclosed gaps need to repair the welds on the tested oil tanks. The repair welding workload is large for the staff, which increases the labor intensity of the staff and also affects the production efficiency of the oil tank. Utility Model Content

[0005] Preferably, the outer wall of the rolling rod is rollingly connected to the rear sealing plate of the fuel tank, the outer wall of the rear sealing plate of the fuel tank is slidably connected to the outer wall of the sealing plate positioning block, the top of the rear sealing plate of the fuel tank is slidably connected to the outer side plate of the fuel tank, the outer wall of the outer side plate of the fuel tank is slidably connected to the rear side plate of the fuel tank, the outer wall of the top of the outer side plate of the fuel tank is slidably connected to the corner positioning block, the side wall of the corner positioning block is slidably connected to the outer wall of the rear side plate of the fuel tank, the outer wall of the rear side plate of the fuel tank is slidably connected to the side plate positioning block, the top of the side plate positioning block and the bottom of the corner positioning block are both fixedly connected to the outer wall of the transversely welded positioning seat. By providing the rolling rod and the anti-scratch groove, it is convenient to fit the various components of the fuel tank while also making the contact area between the components and the tooling smaller, thereby reducing the friction area between the fuel tank and the tooling after the welding is removed, which not only makes it convenient for the staff to move the fuel tank during the production process, but also makes fewer friction marks left inside the fuel tank.

[0006] Preferably, a first manual reversing valve is arranged above the welding base, a second manual reversing valve is arranged below the welding base, and a third manual reversing valve is arranged on the left side of the welding base. The outer wall of the first manual reversing valve is fixedly connected to a transverse clamping cylinder through an air pump connecting pipe, the outer wall of the second manual reversing valve is fixedly connected to a rotational positioning clamping cylinder through an air pump connecting pipe, and the outer wall of the third manual reversing valve is fixedly connected to a vertical clamping cylinder through an air pump connecting pipe. By setting up the welding tool, various parts of the oil tank are positioned and fitted separately, waiting for welding. Since the positioned and assembled oil tank components are squeezed, the gaps between the components are compressed, so that the subsequent welding makes the weld of the oil tank smaller.

[0007] The beneficial effects of the utility model are as follows:

[0008] 1. The utility model positions and fits the various parts of the fuel tank respectively by setting the welding tool, and then waits for welding. Since the positioned and assembled fuel tank parts are squeezed, the gaps between the various parts are compressed, so that the subsequent welding makes the weld of the fuel tank smaller and the airtightness better, thereby reducing the number of fuel tanks that need to be repaired.

[0009] 2. The utility model provides rolling rods and anti-scratch grooves, which facilitate the fitting of various components of the fuel tank and also reduce the contact area between the components and the tooling, thereby reducing the friction area between the fuel tank and the tooling after the welding is removed. This not only makes it convenient for workers to move the fuel tank during the production process, but also reduces the friction marks left inside the fuel tank, thereby improving the quality of the fuel tank product.

When it is necessary to assemble the various parts of the fuel tank During welding, it is necessary to assemble the fuel tank rear cover plate 18, the fuel tank rear side plate 14 and the fuel tank outer side plate 9 in sequence. For the fuel tank rear cover plate 18, it is selected to perform three-point positioning by welding on the welding base 1, the cover plate positioning block 6 and the vertical welding positioning seat 3. For the positioning of the fuel tank rear side plate 14, it is selected to complete the three-point positioning of the fuel tank rear side plate 14 through the fixed fuel tank rear cover plate 18, the side plate positioning block 13, the corner positioning block 12, and the vertical welding positioning seat 3.

[0018] Working principle:

[0019] When using the loader tank welding fixture, the welding base 1 vertically fixes the vertical welding positioning seat 3 through the connecting plate 2, and then the horizontal welding positioning seat 4 is fixed on the vertical welding positioning seat 3 to form the main structure of the welding fixture. When it is necessary to weld and assemble the various parts of the tank, it is necessary to assemble the tank rear sealing plate 18, the tank rear side plate 14 and the tank outer side plate 9 in sequence. For the tank rear sealing plate 18, it is selected to perform three-point positioning of welding on the welding base 1, the sealing plate positioning block 6 and the vertical welding positioning seat 3, and by rotating the second manual reversing valve 10, the rotary positioning clamping cylinder 11 is driven to press down and clamp the tank rear sealing plate 18, so that the tank rear sealing plate 18 is positioned and fixed;

[0020] For positioning of the rear side plate 14 of the oil tank, the three-point positioning of the rear side plate 14 of the oil tank is completed by fixing the rear sealing plate 18 of the oil tank, the side plate positioning block 13, the corner positioning block 12, and the vertically welded positioning seat 3. When the positioning is completed, the staff rotates the third manual reversing valve 15, thereby driving the vertical clamping cylinder 16 to move and clamp the rear side plate 14 of the oil tank;

[0021] For the outer plate 9 of the fuel tank, the three-point positioning of the outer plate 9 of the fuel tank is completed by fixing the rear sealing plate 18 of the fuel tank, the top of the corner positioning block 12, the vertical welding positioning seat 3 and the horizontal welding positioning seat 4. The staff turns the first manual reversing valve 7 to make the horizontal clamping cylinder 8 clamp the outer plate 9 of the fuel tank downward. At the same time, under the limit of the outer plate 9 of the fuel tank by the rotating positioning clamping cylinder 11, the entire positioning of the fuel tank component structure is completed, so as to facilitate subsequent welding. By positioning and clamping the rear sealing plate 18 of the fuel tank, the outer plate 9 of the fuel tank and the rear side plate 14 of the fuel tank, the relative position and size of the plates of the box body are guaranteed. At the same time, by using cylinder clamping, some deformed plates can be corrected and welded, ensuring the close fit between the plates, thereby improving the welding quality and welding air tightness of the fuel tank, and reducing the subsequent repair welding parts.

[0022] After welding is completed, release the rotary positioning clamping cylinder 11, so that the oil tank welded body can be easily withdrawn from the tooling through the rolling rod 5, and the positioning step can be performed again. The base is designed with a rolling rod 5, so that the staff can easily push the rear cover plate 18 of the oil tank into the tooling for positioning, and after welding is completed, the entire oil tank body can be easily withdrawn from the tooling, which reduces the labor intensity of the workers and improves the production efficiency of the loader oil tank. At the same time, the rolling rod 5 and the anti-scratch groove 17 reduce the contact surface between the tooling and the box structure, so that the box is less scratched when withdrawn.
