[0002] Aluminum alloy car bodies are welcomed by urban transportation companies and railway transportation departments around the world because of their advantages of light weight, corrosion resistance, good appearance flatness and easy manufacturing of complex and beautiful curved car bodies. Currently, there are more than 30,000 aluminum alloy urban rail vehicles and railway transportation vehicles in operation, and some developing countries are also vigorously developing aluminum alloy car bodies and have the ability to mass-produce aluminum alloy car bodies.

[0003] With the increasing output, on-site construction efficiency needs to be improved, especially the positioning requirements for the installation holes of aluminum alloy subway roof components are high. Previously, separate roof panels were processed and then welded together. However, due to the welding shrinkage of the roof assembly, the installation holes of the components after the single profile processing and welding could not meet the dimensional accuracy, and the production efficiency could not be improved.

[0004] Therefore, the roof needs to be processed after assembly welding, and the component mounting holes of the welded roof need to be processed as a whole to ensure the accuracy of the processing dimensions. This requires the design of special processing tooling to meet the technical requirements to ensure the processing accuracy and production efficiency of the component mounting holes.

[0026] The names of the messages or information exchanged between multiple devices in the implementation manner of the present utility model are only used for illustrative purposes, and are not used to limit the scope of these messages or information. Example

[0027] like Figure 1-4 As shown, a subway car roof integral processing tool includes a base 1, slideways are arranged on both sides of the upper end surface of the base 1, a clamping component is arranged on the slideways, and pulleys are arranged on the lower end surfaces of the clamping component. The pulleys can be used to move on the slideways, so that the clamping component can be conveniently arranged on a boss 2 near the middle position of the base 1, and a middle positioning reference block 3 is arranged on the boss 2.

[0028] A positioning groove 4 is provided in the middle of the upper end surface of the boss 2, and a positioning protrusion 5 is provided in the middle of the lower end surface of the middle positioning reference block 3. The middle positioning reference is fixed in the positioning groove 4 on the boss 2 by the positioning protrusion 5.

[0029] The middle positioning reference block 3 is provided with a vehicle roof 6 to be processed, and both sides of the upper end surface of the middle positioning reference are provided with a weld avoidance groove 7 for avoiding the weld on the vehicle roof 6 to be processed.

[0030] The clamping device assembly includes a first clamping device assembly 8 and a second clamping device assembly 9. The first clamping device assembly 8 and the second clamping device assembly 9 can slide left and right on their respective corresponding slideways.

[0031] The first clamping device assembly 8 is provided with a first clamping device 10 and a side anti-shape block 11, the upper end surface of the side anti-shape block 11 includes a first curved surface and a first plane, the first curved surface and the first plane are an integrated structure, and two first bolt holes 12 are provided on the lower end surface of the side anti-shape block 11, and the side anti-shape block 11 is fixed to the first clamping device assembly 8 by using the first bolts through the first bolt holes 12. The side anti-shape block 11 is placed in a position close to the boss 2, and the first curved surface is close to the boss 2. The curvature of the first curved surface matches the curvature of the roof 6 it contacts, so that one side of the roof 6 to be processed is placed on the side anti-shape block 11 for convenience.

[0032] The second clamping device assembly 9 is provided with a second clamping device 13 and a second side anti-shape block 14. The upper end surface of the second side anti-shape block 14 includes a second curved surface and a second plane. The second curved surface and the second plane are an integrated structure. Two second bolt holes 15 are provided on the lower end surface of the second side anti-shape block 14. The second side anti-shape block 14 is fixed to the second clamping device assembly 9 by means of second bolts through the second bolt holes 15. The second side anti-shape block 14 is placed in a position close to the boss 2, and the second curved surface is close to the boss 2. The curvature of the second curved surface matches the curvature of the roof 6 it contacts, so that the other side of the roof 6 to be processed is placed on the second side anti-shape block 14 for convenience.

[0033] A plane step 16 is arranged on the second plane. The second plane and the plane step 16 are an integrated structure. The plane step 16 is used to limit the position of the vehicle roof 6 to be processed to prevent the processing position from being offset.

[0034] The overall straightness of the middle positioning reference block when placed is equal to 1 mm, and the overall straightness of the two side protection blocks when placed is also equal to 1 mm.

[0035] When using this tooling for processing, first check the tooling according to the standard contour template 17, adjust the straightness of the middle positioning reference block 3 and the second side anti-shape block 14 of the tooling, and fix them after adjustment. The specific adjustment is: place the standard contour template 17 vertically on the middle positioning reference block 3, and then align the template center line 18 on the standard contour template 17 with the reference center line 19 on the middle positioning reference block 3 to adjust and ensure that the straightness of the middle positioning reference block 3 is equal to 1, and then move the second clamping component to make it close to the boss 2, and use the position of the flat step 16 on the second side anti-shape block 14 on it to resist the standard contour template 17, so that the left end face of the standard contour template 17 and the right end face of the flat step on the second side anti-shape block face it, so as to ensure that the straightness of the second side anti-shape block is equal to 1. After adjustment, the overall straightness is equal to 1, and then fix the second clamping component so that it cannot move, and the first side anti-shape block 11 and the boss 2 can leave a certain width according to the standard contour template 17. There are about 20 sets of such tooling on site, which are calibrated in turn. After the calibration, the standard contour template 17 is removed, and the roof 6 to be processed is hoisted. One side of the roof 6 is placed on the arc-shaped plane on the second side anti-shape block 14, and the end of the roof 6 close to the plane step is aligned with the vertical surface of the plane step 16. After placing it, the corresponding pneumatic clamping arm is controlled, and the second clamping device 13 is used to clamp the upper end surface of the roof 6 on the corresponding side, and then the first clamping component is moved so that the arc-shaped plane on the side anti-shape block on the first clamping component is in contact with the contour of the roof 6. Then the corresponding pneumatic clamping arm is controlled, and the first clamping device 10 is used to clamp and fix the other side of the roof 6 to prevent the tool from shaking. After fixing, the tool alignment processing is started. The overall structure is simple, which effectively meets the conditions for the overall processing of the roof 6, better guarantees the positioning accuracy of the mounting holes of the roof 6 components, and improves the production efficiency.
