[0028] As Figures 1-6 shown, a robot welding mother-child quick-change tooling for a paver screed board includes a sub-tool for installing the screed board 15 and a mother tool for detachably installing the sub-tool.

[0029] The sub-tool includes a sub-tool main body 6. The lower end of the sub-tool main body 6 is connected to the bottom plate 18 through a connecting frame 17. A positioning backing plate 8, a height backing plate and a pressing assembly are installed on the sub-tool main body 6. The positioning backing plate 8 and the height backing plate are used for the positioning and support of the screed board 15, and the pressing assembly is used to press the screed board 15 on the sub-tool main body 6.

[0030] The mother tool includes a mother tool main body 1. A positioning assembly and a fastening assembly are installed on the mother tool main body 1. The sub-tool is installed on the mother tool main body 1 through the positioning assembly and fixed through the fastening assembly.

[0031] In some embodiments, such as Figure 5 , Figure 6As shown, the height pads include a rear height pad 13 and a left height pad 14. The two height pads and the positioning pad 8 have the same height. The positioning pad 8 is located on the front side of the sub-tool body 6. The installation position of the screed 15 is positioned by one positioning pad 8. The positioning pad 8 cooperates with the rear height pad 13 and the left height pad 14 to form a three-sided positioning support structure for installing the screed 15.

[0032] In some embodiments, as Figure 2 , Figure 5 and Figure 6 shown, the pressing assembly includes a pressing pad installed on the sub-tool body 6. A pressing plate 9 is installed on the pressing pad and fastened by a bolt 11. When it is necessary to press the screed 15, the bolt 11 is rotated to make the pressing plate 9 fasten the screed 15 on the positioning pad 8 or the height pad, so that the screed 15 is fixed on the sub-tool body 6.

[0033] In some embodiments, as Figure 2 , Figure 5 and Figure 6 shown, a gasket 10 is installed between the bolt 11 and the pressing plate 9. The gasket 10 makes it more convenient for the bolt 11 to rotate and press the pressing plate 9, improving the fastening property of the pressing plate 9.

[0034] In some embodiments, as Figure 2 , Figures 4-6 shown, the pressing assembly includes a front pressing assembly installed on the front side of the sub-tool body 6 and a rear pressing assembly installed on the rear side of the sub-tool body 6;

[0035] The front pressing assembly includes a front pressing pad 7, a pressing plate 9, a gasket 10 and a bolt 11. The rear pressing assembly includes a rear pressing pad 12, a pressing plate 9, a gasket 10 and a bolt 11. Relying on the provided front and rear pressing assemblies, the screed 15 can be fixed on the sub-tool body 6.

[0036] In some embodiments, as Figure 2 , Figure 3 and Figure 6 shown, guide posts 5 for guiding the installation of the sub-tool are installed on the master tool body 1. The number of guide posts 5 can be set to four, and they are arranged in a pairwise symmetric manner on the front and rear sides of the master tool body 1. On the front and rear sides of the bottom plate 18 below the sub-tool body 6, guide grooves cooperating with the guide posts 5 are correspondingly provided. Relying on the cooperation of the guide posts 5 and the guide grooves, it is convenient for the sub-tool body 6 to be quickly installed on the surface of the master tool body 1 from top to bottom, with high assembly accuracy and high efficiency. Further, as Figure 3 shown, the upper end of the guide post 5 is conical. Relying on the taper of the upper end of the guide post 5, it is ensured that the guide groove of the bottom plate 18 can be accurately installed on the surface of the master tool body 1 along the guide post 5.

[0037] In some embodiments, as Figure 2 , Figure 3 and Figure 6 shown, the positioning assembly includes a positioning shaft 3 installed on the main body 1 of the mother tooling and a positioning hole at the center of the bottom plate 18 below the main body 6 of the sub-tool. When the main body 6 of the sub-tool is installed in place on the main body 1 of the mother tooling, the positioning shaft 3 on the main body 1 of the mother tooling is stuck in the positioning hole of the main body 6 of the sub-tool to achieve front-back and left-right direction limiting. In addition, an anti-rotation pin 4 is provided on the right side of the main body 1 of the mother tooling, and a limiting groove 16 cooperating with the anti-rotation pin 4 is provided on the right side of the bottom plate 18. The anti-rotation pin 4 is cooperatively installed in the limiting groove 16 to prevent the main body 6 of the sub-tool from rotating relative to the main body 1 of the mother tooling.

[0038] In some embodiments, as Figure 2 , Figure 6 shown, the fastening assembly includes air cylinders 2 evenly distributed on the main body 1 of the mother tooling. The number of air cylinders 2 can be three, four, etc. After the main body 6 of the sub-tool is installed on the main body 1 of the mother tooling, the air cylinders 2 are closed, and the main body 6 of the sub-tool is clamped by the air cylinders 2. When the screed 15 needs to be replaced, the air cylinders 2 are opened, the sub-tool and the screed 15 are lifted by a lifting device, and then the newly replaced screed 15 and the new sub-tool are reassembled on the mother tooling.

[0039] During use, the screed 15 is hoisted onto the main body 6 of the sub-tool to make the bottom surface of the screed 15 closely attached to the positioning pad 8. At the same time, through the rear height pad 13 and the left height pad 14, the screed 15 is in a horizontal support state. Then, the bolt 11 is tightened to make the pressing plate 9 clamp the screed 15 on the positioning pad 8, the rear height pad 13, and the left height pad 14. The air cylinders 2 are opened, and the screed 15 and the main body 6 of the sub-tool are hoisted onto the main body 1 of the mother tooling, and the main body 6 of the sub-tool slides along the guiding column 5 on the main body 1 of the mother tooling until it is closely attached to the positioning shaft 3 and the anti-rotation pin 4. Then, the air cylinders 2 are closed to clamp the main body 6 of the sub-tool.

[0040] The robot welding mother-daughter quick-change tooling for the screed of the paver of the present utility model installs the screed on the sub-tool, and the sub-tool is detachably installed on the mother tooling. When the product needs to be switched, the screed and the sub-tool are directly separated from the mother tooling together, so as to realize the quick loading and unloading and die change of the screed workpiece. Using this tooling solves the problem of long die change time for welding workpieces of multiple types of screeds and improves the welding efficiency.

[0041] In addition, those skilled in the art can understand that although some of the embodiments described herein include certain features contained in other embodiments rather than other features, the combination of features of different embodiments also means that it is within the protection scope of the present utility model and forms different embodiments. For example, in the above embodiments, those skilled in the art can use them in a combined manner according to the known technical solutions and the technical problems to be solved by this application.
