[0002] Excavator cover is an important part of the excavator, usually used to protect the engine and other key components of the excavator, prevent dust, water and other debris from entering the machine, so as to maintain the normal operation of the machine and extend its service life.

[0003] Reference Figure 1 The excavator cover includes a bottom plate 1, four bottom positioning holes 2 are formed on the bottom plate 1, a square hole 3 is formed on the bottom plate 1, and an inner frame 4 is formed at the edge of the square hole 3. The excavator cover also includes two protrusion bodies 5, each of which has a protrusion positioning hole 6 formed thereon, and protrusion nuts 7 corresponding to the protrusion positioning holes 6 are resistance-welded on the two protrusion bodies 5. The operator needs to manually weld the two protrusion bodies 5 to the bottom plate 1, so that the finished excavator cover is a whole after welding.

[0004] During the welding process, it is difficult for the above-mentioned bracket to simultaneously fix the position of the bump body and the base plate and weld them as a whole, which makes it difficult to accurately locate the relative position of the bump body and the base plate, and the weld position is prone to deviation, resulting in uneven weld quality, which is time-consuming and labor-intensive and leads to low production efficiency. Summary of the invention

[0014] Through the above technical solution, the operator can use the horizontal rod to conveniently rotate the vertical rod, and the vertical rod drives the bump positioning column to rotate, so that the bump positioning column passes through the fixing frame and is threadedly connected to the bump nut, which saves time and effort while improving welding efficiency.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 2 This application is described in further detail.

[0030] The embodiment of the present application discloses a welding tool for an excavator cover plate.

[0031] Reference Figure 2The welding tooling for the excavator cover plate includes a base 8, and a plurality of weight-reducing holes 21 of different sizes are opened on the base 8. The design of the weight-reducing holes 21 can effectively reduce the overall weight of the base 8, reduce the physical exertion of the operator in moving the overall welding tooling, realize the lightweight of the overall structure, and facilitate transportation. The operator can centrally clean the welding slag on the base 8 through the weight-reducing holes 21, thereby improving work efficiency. In the embodiment of the present application, the base 8 can be split into a first bottom block 22 and a second bottom block 23 according to the actual use environment. The first bottom block 22 and the second bottom block 23 are connected by a connecting seat 24. The two ends of the connecting seat 24 are respectively bolted to the first bottom block 22 and the second bottom block 23, dividing the base 8 into two, realizing a detachable design. When the welding tooling is idle, it can be disassembled and stacked to save space.

[0032] Reference Figure 2 The base 8 is provided with a first fixing unit for fixing the bottom plate 1, and the first fixing unit includes a bottom positioning column 9 provided on the base 8 and matching the size of the bottom positioning hole 2. The bottom plate 1 is mounted on the base 8 and the bottom positioning column 9 passes through the bottom positioning hole 2. Two support frames 18 are plugged into the base 8, and the bottom plate 1 is mounted on the two support frames 18. The support frames 18 support the bottom plate 1, improve the stability of the bottom plate 1, and increase the distance between the bottom plate 1 and the base 8, which is convenient for the operator to clean the welding slag later, and improve the weld quality and welding efficiency.

[0033] Reference Figure 2 , a quick clamp 19 is provided on the base 8, and the base plate 1 is pressed between the clamp end of the quick clamp 19 and the base 8. The base plate 1 is pressed between the clamp end of the quick clamp 19 and the base 8 by the quick clamp 19, thereby reducing the possibility of shaking of the base plate 1, and achieving the stability of the base plate 1 while fixing the base plate 1 separately. A mounting bolt 20 is passed through the base 8 of the quick clamp 19, and a mounting hole is provided on the base 8. The mounting bolt 20 is threaded into the mounting hole. In the embodiment of the present application, a plurality of mounting holes are provided on the base 8, so that the operator can adjust the position of the quick clamp 19. The operator can remove the quick clamp 19 from the base 8 by disassembling the bolts, which is more flexible and convenient for subsequent replacement of different models of quick clamps 19.

[0034] Reference Figure 2The base 8 is also provided with a second fixing unit for fixing the two protrusion bodies 5 at the same time. The second fixing unit includes a mounting seat 10 provided on the base 8. Two support arms 11 are hinged on the mounting seat 10. A fixing frame 12 is provided between the two support arms 11. Two protrusion positioning columns 13 respectively matching the two protrusion nuts 7 are threadedly connected to the fixing frame 12. The two protrusion positioning columns 13 are respectively threadedly connected to the protrusion nuts 7. A reinforcing rib 14 is provided between the two support arms 11. The reinforcing rib 14 is located between the mounting seat 10 and the fixing frame 12. The design of the reinforcing rib 14 can increase the bearing capacity of the support arm 11, so that the support arm 11 is not easily deformed or broken when facing external force, thereby enhancing the stability of the fixing frame 12.

[0035] Reference Figure 2 , the ends of the two protrusion positioning columns 13 facing away from the base 8 are fixedly connected with a vertical rod 15, and the operator can use the vertical rod 15 to conveniently lift or lower the fixing frame 12, saving time and effort, and saving the time of taking and placing the protrusion body 5. The ends of the two vertical rods 15 facing away from the protrusion positioning column 13 are fixedly connected with a cross bar 16, and the operator can use the cross bar 16 to conveniently rotate the vertical rod 15, and the vertical rod 15 drives the protrusion positioning column 13 to rotate, so that the protrusion positioning column 13 passes through the fixing frame 12 and is threadedly connected to the protrusion nut 7, saving time and effort while improving the welding efficiency. Two blocks 17 are inserted on the surface of the fixing frame 12 facing the base 8, and the two protrusion bodies 5 are respectively located between the two blocks 17 and the inner frame 4. Therefore, the block 17 limits the position of the protrusion body 5 between the block 17 and the inner frame 4, reducing the possibility of the protrusion body 5 offset during welding, improving the stability of the placement of the protrusion body 5, and improving the welding quality.

[0036] The implementation principle of the embodiment of the present application is as follows: when it is necessary to weld the two convex block bodies 5 to the bottom plate 1, the operator sets the bottom plate 1 on the base 8, and makes the bottom positioning column 9 pass through the bottom positioning hole 2 of the bottom plate 1, so as to realize the positioning of the bottom plate 1, and the quick clamp 19 presses the bottom plate 1 between the clamp end of the quick clamp 19 and the base 8, so as to realize the fixation of the bottom plate 1; the two convex block bodies 5 are attached to both sides of the inner frame 4 of the bottom plate 1 in the length direction, so that the convex nut 7 of the convex block body 5 is placed toward the bottom plate 1, and the operator rotates the convex block body 5 to fix the convex block body 5. The block positioning column 13 allows the bump positioning column 13 to pass through the fixing frame 12 and then be threadedly connected to the bump nut 7, thereby fixing the bump body 5. Subsequently, the operator uses welding equipment to weld the end faces of the two bump bodies 5 that contact the base plate 1, uses the first fixing unit to fix the base plate 1, and uses the second fixing unit to fix the two bump bodies 5. This makes it convenient for the operator to perform welding operations, and the base plate 1 and the two bump bodies 5 are not prone to shaking during the welding process, thereby improving the weld quality and production efficiency.
