[0002] After a period of rapid development in the railway sector, the EMU manufacturing industry has now entered a stable phase, with various orders featuring small-batch, multi-model alternating production.

[0003] Each aluminum alloy car body has left and right side walls, which need to be processed on large-scale FOOKE processing centers for windows, doorways, end face interfaces and C-shaped grooves. The processing time is long. Therefore, two sets of reverse processing tooling are required to process the side walls of each model. However, FOOKE processing centers are expensive. If there are many models in production, more processing centers will inevitably be occupied, which is not conducive to reducing the utilization rate of the workshop area and arranging production plans. If the tooling is replaced as a whole, there will be problems with how to store and replace a large number of tooling and how to be efficient.

[0113] It should be noted that the side wall inversion processing device of the embodiment of the present application has the following technical details during its actual design and production:

[0114] The side wall inversion processing device adopts a flexible, multi-point forming and modular design concept. It uses the bottom linear guide rail 1 laid on the machining center as the installation basis. The crossbeam 2 can move longitudinally along the bottom linear guide rail 1 and is locked by the rack locking device 3 to ensure that the crossbeam 2 does not move.

[0115] The crossbeam 2 is equipped with an upper side beam positioning seat 4, an upper side beam nylon support block 5, a lower side beam positioning seat 6, a lower side beam nylon support block 7, a pneumatic support device 8, an automatic deflection adjustment device 9, a hydraulic top deflection device 10 and a lower side beam positioning seat stopping device 11.

[0116] Among them, the upper side beam nylon support block 5, the lower side beam nylon support block 7 and the pneumatic support device 8 are contoured to the outer contour of the side wall. By replacing different side beam nylon support block structures, different side wall outer contours can be contoured.

[0117] The position of the upper side beam positioning seat 4 is positioned by the automatic deflection adjustment device 9, and the deflection during side wall processing is achieved by the hydraulic top deflection device 10 horizontally pushing the lower side beam positioning seat 6;

[0118] The side wall is pressed by the hydraulic pressure arm 12 of the upper side beam positioning seat and the hydraulic pressure arm 13 of the lower side beam positioning seat.

[0119] Furthermore, the upper side beam nylon support block 5 and the lower side beam nylon support block 7 are both inserted into the positioning groove horizontally to achieve accurate positioning and quick replacement. The pneumatic support device 8 can automatically rise and fall in the vertical direction to press against the side wall window plane. The three cooperate to imitate the contour of the side wall. By replacing the upper and lower side beam nylon support blocks corresponding to different side walls, flexible contour transformation can be achieved.

[0120] In addition, the automatic deflection adjustment device 9 and the lower side beam positioning seat stop device 11 can automatically rotate the turntables of the two devices 90° in one direction under the push of the hydraulic cylinder to replace the deflection plates of different side walls and change the position of the upper side beam positioning seat 4, thereby realizing the side wall inversion processing device to automatically adjust different side wall deflection values to meet the side wall product processing requirements.

[0121] Specifically, the crossbeam 2 can move longitudinally along the bottom linear guide rail 1, and is pressed down by the screw 16 of the rack locking device 3, so that the rack of the rack locking device 3 is engaged with the rack composed of the bottom linear guide rail 1, locking and ensuring that the crossbeam 2 does not move, so as to realize changes in different side wall lengths and window positions, and ensure that the side wall inversion processing device can reliably support and press the side wall.

[0122] Specifically, the pneumatic support device 8 is used to support the window portion of the side wall. It uses a pneumatic motor 25 to drive the movable support head 30 to rise, and automatically stops after it touches the side wall.

[0123] As shown in the accompanying drawings Figure 1 As shown, it is the side wall structure of the EMU;

[0124] The side walls of the EMU are made of multiple aluminum profiles welded together. The profile length ranges from 20 meters to 26 meters, and the cross-section shape is irregular. The outer surface is smooth with multiple curves and the inner surface has a C-shaped groove. The parts that need to be processed are windows, doorways, C-shaped grooves, end face interfaces, etc.

[0125] As shown in the accompanying drawings Figure 2 and Figure 3 As shown, the side wall inversion processing device provided in the embodiment of the present application is used to position and support the side wall, eject the side wall deflection required by the side walls of different vehicle models, and ensure that the side wall does not shift or vibrate during the entire processing process.

[0126] As shown in the accompanying drawings Figure 3 As shown, the tooling is adjusted according to the side wall vehicle model to be produced, the lower side beam positioning seat 6 retreats to the final position horizontally to the right, the pneumatic support device 8 drops to the lowest position, the upper side beam positioning seat hydraulic pressure arm 12 and the lower side beam positioning seat hydraulic pressure arm 13 are opened, the overhead crane lifts the side wall in an inverted state and drops it onto the side wall inversion processing device, the hydraulic top-bending device 10 is started to push the side wall horizontally to the left against the upper side beam nylon support block 5, the upper side beam positioning seat hydraulic pressure arm 12 and the lower side beam positioning seat hydraulic pressure arm 13 are pressed down, the pneumatic motor 25 is started, and the pneumatic support device 8 rises and presses against the outer contour surface of the side wall. At this point, the side wall pressing and fixing work is completed and the processing begins.

[0127] As shown in the accompanying drawings Figure 4 and Figure 5 As shown, this is the replacement method of the upper side beam positioning seat 4 and the lower side beam positioning seat 6. The upper side beam nylon support block 5 and the lower side beam nylon support block 7 both adopt a quick-change structure that is inserted horizontally into the positioning groove. If the vehicle model needs to be changed, the worker only needs to pull out the upper and lower side beam nylon support blocks horizontally and then push them in. At the same time, as shown in the accompanying drawings of the specification Figure 3 As shown, when the side wall is squeezed, under the lateral action of the hydraulic top-flexing device 10, the lower side beam nylon support block 7 and the upper side beam nylon support block 5 can fit well with the side wall side beam to ensure positioning accuracy.

[0128] As shown in the accompanying drawings Figure 1 、 Figure 6 and Figure 7 As shown in the figure, this is the structure of the rack locking device 3. The crossbeam 2 can move along the linear guide 14 and slider 140 of the bottom linear guide 1. The locking rack block 17, guide screw 18 and locking pull shaft 19 are assembled together. The nut 20, stop screw 21 and locking sleeve 15 are assembled together. The screw 16 rotates and presses downward to drive the locking rack block 17 to engage with the lower rack 22 of the bottom linear guide 1, thereby fixing the crossbeam 2.

[0129] On the contrary, the screw 16 is rotated and lifted, the engaged rack is disengaged, and the crossbeam 2 can be easily moved to the use position. This structure is simple and reliable, and can make this side wall inversion processing device applicable to the side walls of all models.

[0130] It should be noted that the crossbeam 2 can be a cast iron part.

[0131] As shown in the accompanying drawings Figure 8 and Figure 9 As shown, this is the structure of the pneumatic support device 8. In the structure of the pneumatic support device 8:

[0132] The bottom shaft 26 and the transmission screw 27 are connected together by a pin;

[0133] The nut shaft 24 and the movable support head 30 are connected together by a pin shaft. The movable support head 30 can swing to a certain angle to adapt to the changes in the side wall profile, ensuring that the movable support head 30 can completely adhere to the side wall profile;

[0134] The transmission screw 27 and the nut shaft 24 form a T-shaped threaded transmission pair. The nut shaft 24 can move up and down along the guide sleeve 31, and the guide block 29 can prevent the nut shaft 24 from rotating.

[0135] The working principle of the pneumatic support device 8 is that the pneumatic motor 25 is ventilated, driving the transmission screw 27 to rotate, thereby driving the movable support head 30 to move up and down. After the movable support head 30 is abutted against the side wall surface and a certain pressure is generated, it automatically stops and the air source is turned off. At this time, the side wall can be fully supported and will not vibrate. This structure has been proven to ensure the processing quality and effectively reduce the noise generated by vibration. The entire structure is installed on the cast iron beam 2 through the support base plate 32, and the position can be easily adjusted. It is suitable for the processing of side walls of all models.

[0139] It should be noted that the mark A in the drawings of the specification of the embodiment of the present application corresponds to the side wall.
