[0001] The present application relates to the technical field of sheet metal processing, and in particular to a clamping tool for an excavator support. Background Art

[0002] The excavator bracket is an important part of the excavator. It is mainly responsible for the support and stability of the excavator and is usually made of sheet metal. During the manufacturing process of the excavator bracket, the components need to be welded into a whole.

[0003] Reference Figure 1 The excavator support includes a bottom plate 1, which has two bottom positioning holes 2. The excavator support also includes a vertical plate body 3 and two short plate bodies 4. In the finished excavator support, the vertical plate body 3 is arranged perpendicular to the bottom plate 1, and two vertical plate positioning holes 5 are arranged on the vertical plate body 3. Two short plate bodies 4 respectively have two short plate positioning holes 6. Short plate nuts 7 corresponding to the short plate positioning holes 6 are respectively welded on the two short plate bodies 4. The operator needs to manually weld the two short plate bodies 4 to the side of the bottom plate 1 and vertically weld the vertical plate body 3 to the bottom plate 1, so that the finished excavator support is a whole after welding.

[0004] During the welding process of the above-mentioned excavator bracket, it is difficult to fix the bottom plate, the vertical plate body and the two short plate bodies at the same time and weld them into a whole, which makes it difficult to accurately locate the relative positions of the bottom plate, the vertical plate body and the two short plate bodies, and the weld position is prone to deviation, resulting in uneven quality of the weld, which is time-consuming and labor-intensive and leads to low production efficiency. Summary of the invention

[0005] In order to help solve the problem that it is difficult to simultaneously fix the base plate, the vertical plate body and the two short plate bodies in the existing welding process, and the welding efficiency is low, the present application provides a clamping tool for an excavator support, which adopts the following technical solution: it includes a base, the base is provided with a first fixing unit for fixing the base plate, the base is provided with a second fixing unit for fixing the vertical plate body and a third fixing unit for fixing the two short plate bodies, the first fixing unit includes a bottom positioning column arranged on the base and matching the bottom positioning hole, the base plate is mounted on the base and the bottom positioning column passes through the bottom positioning hole.

[0006] Through the above technical scheme, when it is necessary to weld the bottom plate, the vertical plate body and the two short plate bodies into a finished excavator bracket, the operator sets up the bottom plate on the base, passes the bottom positioning column through the bottom positioning hole of the bottom plate to realize the positioning of the bottom plate; places the vertical plate body perpendicular to the bottom plate, and uses the second fixing unit to fix the position of the vertical plate body, and then the operator uses the welding equipment to weld the end surface where the vertical plate body contacts the bottom plate; places the two short plate bodies against the side surface of the bottom plate, and uses the third fixing unit to fix the position of the short plate body, and the operator uses the welding equipment to weld the end surface where the two short plate bodies contact the bottom plate, which is convenient for the operator to perform welding operations, and at the same time, the bottom plate, the vertical plate body and the two short plate bodies are not easy to shake during the welding process, thereby improving the weld quality and production efficiency.

[0009] In a specific possible implementation manner, the pressing hole is a waist-shaped hole.

[0010] Through the above technical solution, the waist-shaped hole is convenient for adjusting the position of the second supporting bolt, which is more flexible and convenient for adjusting the clamping force of the pressure plate on the bottom plate.

[0011] In a specific possible implementation manner, a stopper is provided on the base, and the stopper is in contact with the bottom plate.

[0012] Through the above technical solution, the stopper limits the position of the bottom plate, reduces the possibility of the bottom plate being offset, and improves the stability of the bottom plate position.

[0014] Through the above technical solution, the operator places the vertical plate body perpendicular to the bottom plate, inserts the vertical plate positioning column through the vertical plate body and the fixing frame in sequence, then rotates the annular gasket to adjust the position of the annular gasket, and presses the vertical plate body between the fixing frame and the anti-dropping block to achieve the positioning of the vertical plate body. The vertical plate body is controlled separately by the second fixing unit, which reduces the possibility of shaking of the vertical plate body and improves the stability of the welding operation.

[0015] In a specific possible implementation mode, a support block is provided at one end of the fixing frame facing the vertical plate body, and the vertical plate body is mounted on the support block.

The base is provided with a plurality of mounting seats, and quick clamps are provided on the plurality of mounting seats. The two short plate bodies are respectively clamped between the clamping ends of the plurality of quick clamps and the positioning blocks.

[0018] Through the above technical solution, the short board body is pressed tightly between the clamp end of the quick clamp and the positioning block by the quick clamp, thereby reducing the possibility of shaking of the short board body, achieving independent fixation of the short board body and improving the stability of the placement of the short board body.

[0019] In a specific possible implementation scheme, four short board positioning columns matching the short board positioning holes are arranged on the base, and the four short board positioning columns are respectively passed through the positioning blocks and partially located in the short board nuts.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 2-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a clamping tool for an excavator support.

[0032] Reference Figure 2The clamping tooling for the excavator support includes a base 8, on which a plurality of weight-reducing holes 26 of different sizes are opened. The design of the weight-reducing holes 26 can effectively reduce the overall weight of the base 8, reduce the physical exertion of the operator in moving the overall clamping tooling, achieve lightweight overall structure, facilitate handling and improve work efficiency.

[0033] Reference Figure 2 The base 8 is provided with a first fixing unit for fixing the bottom plate 1. 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. The operator mounts the bottom plate 1 on the base 8 and allows the bottom positioning column 9 to pass through the bottom positioning hole 2 of the bottom plate 1 to achieve positioning of the bottom plate 1. Two stoppers 15 are bolted to the base 8. Both stoppers 15 are in contact with the bottom plate 1. The stoppers 15 limit the position of the bottom plate 1, reduce the possibility of the bottom plate 1 being offset, and improve the stability of the placement of the bottom plate 1.

[0034] Reference Figure 2 Three first support bolts 10 are welded on the base 8, and the three first support bolts 10 are evenly distributed on the bottom plate 1. The outer edges of the three first support bolts 10 are threadedly connected with a pressing plate 11, and a clamping hole 12 is opened on the pressing plate 11. The clamping hole 12 is a waist-shaped hole, and a second support bolt 14 is passed through the clamping hole 12. The outer edge of the second support bolt 14 is threadedly connected with a fixing nut 13, and the pressing plate 11 is pressed between the fixing nut 13 and the bottom plate 1.

[0035] Therefore, after the base plate 1 is mounted on the base 8, the operator rotates the fixing nut 13 to press the base plate 1 between the pressure plate 11 and the base 8, thereby reducing the possibility of shaking of the base plate 1 during welding and improving the weld quality and welding stability.

[0036] Reference Figure 2 and Figure 3 The base 8 is provided with a second fixing unit for fixing the vertical plate body 3. The second fixing unit includes a fixing frame 16 provided on the base 8 and two vertical plate positioning columns 17 matching the vertical plate positioning holes 5. The fixing frame 16 is bolted with a support block 20 at one end facing the vertical plate body 3. The vertical plate body 3 is mounted on the support block 20. The support block 20 supports the vertical plate body 3, thereby improving the stability of the placement of the vertical plate body 3 and facilitating subsequent welding operations. The two vertical plate positioning columns 17 are fixedly connected with an anti-slip block 18. The outer edge of the vertical plate positioning column 17 is threadedly connected with an annular gasket 19. The vertical plate positioning column 17 passes through the vertical plate body 3 and the fixing frame 16 in sequence, and the vertical plate body 3 is pressed tightly between the anti-slip block 18 and the annular gasket 19.

[0037] Therefore, the operator places the vertical plate body 3 perpendicular to the bottom plate 1, and sequentially passes the vertical plate positioning column 17 through the vertical plate body 3 and the fixing frame 16, and then rotates the annular gasket 19 to adjust the position of the annular gasket 19, and presses the vertical plate body 3 between the fixing frame 16 and the anti-dropping block 18 to achieve the positioning of the vertical plate body 3. The vertical plate body 3 is controlled separately by the second fixing unit, which reduces the possibility of shaking of the vertical plate body 3 and improves the stability of the welding operation.

[0038] Reference Figure 2 and Figure 3 The base 8 is provided with a third fixing unit for fixing the two short board bodies 4. The third fixing unit includes two positioning blocks 21 provided on the base 8. The two short board bodies 4 are respectively mounted on the two positioning blocks 21. The base 8 is provided with four mounting seats 22. In the embodiment of the present application, the four mounting seats 22 are respectively provided corresponding to the four short board nuts 7. The mounting seats 22 are provided with mounting bolts 25. The base 8 is provided with mounting grooves matching the mounting bolts 25. The mounting bolts 25 are threadedly connected in the mounting grooves.

[0039] Reference Figure 2 and Figure 3 , the four mounting seats 22 are all bolted with quick clamps 23, and the two short plate bodies 4 are respectively pressed between the clamp ends of the quick clamps 23 and the positioning blocks 21. Four short plate positioning columns 24 matching the short plate positioning holes 6 are threadedly connected to the base 8, and the four short plate positioning columns 24 are respectively passed through the positioning blocks 21 and partially located in the short plate nuts 7. The operator sets the short plate body 4 on the positioning blocks 21, so that the short plate positioning columns 24 are passed through the positioning blocks 21 and partially located in the short plate nuts 7, thereby realizing the positioning of the short plate body 4, improving the accuracy of the position of the short plate body 4, and thus improving the welding quality and welding efficiency.

[0040] The implementation principle of the embodiment of the present application is as follows: when it is necessary to weld the bottom plate 1, the vertical plate body 3 and the two short plate bodies 4 into a finished excavator bracket, 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. The operator rotates the fixing nut 13 to press the bottom plate 1 between the pressure plate 11 and the base 8, thereby realizing the positioning and fixing of the bottom plate 1; the vertical plate body 3 is placed perpendicular to the bottom plate 1, and the vertical plate positioning column 17 is sequentially passed through the vertical plate body 3 and the fixing frame 16, and then the annular gasket 19 is rotated to adjust the position of the annular gasket 19, and the vertical plate body 3 is pressed between the fixing frame 16 and the anti-dropping block 18 to realize the positioning of the vertical plate body 3, and then the operator uses the welding equipment to fix the vertical plate body 3. The plate body 3 is welded at the end surface where it contacts the bottom plate 1; finally, the two short plate bodies 4 are placed against the side surface of the bottom plate 1, and the short plate body 4 is mounted on the positioning block 21, so that the short plate positioning column 24 passes through the positioning block 21 and is partially located in the short plate nut 7, thereby realizing the positioning of the short plate body 4, and the short plate body 4 is pressed between the clamping end of the quick clamp 23 and the positioning block 21 by the quick clamp 23, thereby realizing the fixation of the short plate body 4, and the operator uses the welding equipment to weld the two short plate bodies 4 at the end surfaces where they contact the bottom plate 1; while facilitating the operator to perform welding operations, the bottom plate 1, the vertical plate body 3 and the two short plate bodies 4 are not prone to shaking during the welding process, thereby improving the weld quality and production efficiency.
