    DETAILED DESCRIPTION OF THE MODALITIES [0020] The present invention is further described in detail together with the attached drawings:
    6/12 [0021] As shown in Figure 1, a flexible frame for multiveicular co-production line described by the present invention comprises a robotic welding system, a high-speed transport system 3, an intelligent flexible positioning system of floor panel 2, and a flexible side panel positioning and switching system 1. The robotic welding system is used to weld the positioned vehicle body, and is the ultimate mechanism for carrying out the procedure; the high-speed transport system 3 is responsible for transferring the blank automotive body in order to automatically enter the next procedure from the previous one; the intelligent flexible floor panel positioning system 2 cooperates with the high speed transport system 3, and is responsible for positioning and securing the body floor panel in order to process the body floor panel in a flow; the flexible side panel positioning and switching system 1 cooperates with the intelligent floor panel 2 flexible positioning system, positions and secures the body side panel before automatic welding, while maintaining a flexible line joint multiveicular co-production, to improve the applicability of the frame.
    [0022] The robotic welding system consists of a servo-robot for spot welding and an adaptive integral welding servo-gun. The robotic welding system is the system for implementing the welding process, making the welding by the spot welding servo robot with the welding servo gun, which is the last processing stage of the procedure, and then the bodywork. welded automotive would be automatically sent to the next procedure.
    [0023] The high-speed transport system 3 mainly uses a roller conveyor and a trolley in mutual cooperation to transport the blank body, where the high-speed transport process can use a high-grade coding ruler
    7/12 precision and a rail encoder to form a double closed loop control, the coding ruler feeds back the trolley position, and the encoder feeds back the trolley speed. Under the double loop action of speed and position, the speed and position accuracy of the trolley is precisely controlled, and at present a position accuracy of ± 0.7 mm and a 4.7 s transport cycle can be achieved. achieved in this way, both reaching the international advanced level.
    [0024] The intelligent flexible positioning system of floor panel 2 is correspondingly connected to a transfer rail of the high-speed transport system 3, and comprises a high-speed roller belt 4 and eight intelligent positioning units 5. The side panel 1 flexible switching and positioning system comprises a side panel instrument consolidation system 6, an instrument storage system 7, and a switch system and instrument rails 8. The side panel instrument consolidation system 6 corresponds to the side of the intelligent flexible floor panel positioning system 2, and the instrument storage system 7 is connected to the side panel instrument consolidation system 6 by the switching system and instrument rails 8. The positioning system flexible floor panel 2 and flexible panel positioning and switching system el lateral 1 cooperatively position the floor panel and the side panel of the body in white.
    [0025] As shown in Figure 2, the side panel instrument consolidation system comprises a sliding table 11, a side panel instrument positioning platform 12, and a base 10. The side panel instrument positioning platform 12 is fixed on the base 10, corresponds to the side of the intelligent flexible positioning system of the floor panel, and performs the
    8/12 last three-dimensional position adjustment and control over a side panel instrument 14, ensuring the accuracy of instrument positioning. The sliding table 11 is connected to the base 10, and can slide in relation to the base 10. To facilitate positioning and sliding control, the sliding direction of the sliding table 11 is perpendicular to the intelligent flexible positioning system of the floor panel. A support rail 13 for supporting the side panel instrument 14 is fitted on the slide table 11, and the slide table 11 can transfer the received side panel instrument 14 to the side panel instrument positioning platform 12, and exert pressure vertical over the side panel instrument 14, ensuring the reliability of the instrument positioning.
    [0026] The instrument storage system is mainly used to store auxiliary side panel instruments, to ensure that the welding process can be carried out efficiently, quickly, and rhythmically. The instrument storage system comprises two tetrahedral rolling tables, and since a free site is required to replace the side panel instrument at any time, the two tetrahedral rolling tables can simultaneously carry seven side panel instruments. The two tetrahedral rolling tables are correspondingly distributed on two sides of the side panel instrument consolidation system in the direction of transfer of the high speed transport system, where the free site on a tetrahedral rolling table is used to receive the panel instrument. machined finished side, while the other tetrahedral rolling table is used to provide a machined finished side panel instrument, and auxiliary side panel instruments can be adjusted and replaced at any time by rolling the rolling table. As shown in Figure 3, four stations are on a tetrahedral rolling table 20, a rotation rail 21 for switching the panel instrument
    Lateral 9/12 14 is established in each station, respectively, and the side panel instrument 14 is positioned and connected on the rotation rail 21, where the station on the lower front side of the rolling table 20 is an exit site, the from which the auxiliary side panel instrument is produced. The station on the upper rear side of the rolling table 20 is an entry site for receiving or exchanging a new side panel instrument.
    [0027] To ensure that the auxiliary side panel instrument can be replaced easily, a switching system and instrument rails are also fitted between the instrument storage system and the side panel instrument consolidation system. As shown in Figure 4, the switching system and instrument rails comprise four instrument switching rivets 30, an instrument switching transport rail 31, and an instrument return rail 32. The instrument switching transport rail 31 is fixed to the floor, and attached to an exit rotation rail 22 at the exit sites of the two tetrahedral rolling tables 20 and to the support rail 13 of the sliding table 11 in the side panel instrument consolidation system; the instrument return rail 32 is fixed suspended, and joined to an input rotation rail 23 at the entrance sites of the two tetrahedral rolling tables 20, thus forming a closed rail system composed of the instrument switching transport rail 31, the instrument return rail 32, the support rail 13, the input rotation rail 23, and the output rotation rail 22, so that an effective connection is formed between the systems, which ensures the supply and continuous use of side panel instruments. The process of replacing the side panel instrument is triggered by the four instrument switch riveters 30, which are rail transfer rivets driven by friction wheels, and set the riveter's body in motion by the frictional force created by the friction wheels. and the rail. The four instrument switch riveters 30 are located
    10/12 correspondingly on the closed track of the entry and exit sites of the two tetrahedral rolling tables 20, respectively, providing a power tool for the process of adjusting and replacing the side panel instruments at the entry and exit sites.
    [0028] As shown in Figure 5, to maintain coordination and stability, the high-speed roller track 4 and eight intelligent positioning units 5 in the floor panel intelligent flexible positioning system are fixed on the base 10 of the system for consolidating the side panel instrument, respectively, the high-speed roller track 4 corresponds to the high-speed conveyor system, to receive the blank body floor panel in transfer, and the sliding table sliding direction in the system side panel instrument consolidation unit is perpendicular to the transmission direction of the high speed roller belt 4. The intelligent positioning units 5 are uniformly distributed on two sides of the high speed roller belt 4 in two columns, and consist of one fixing mechanism for triaxial positioning, which performs a three-dimensional position adjustment on the floor panel ho received from the body in white, to satisfy the position requirement of different types of vehicles, and to ensure that the positioning process runs smoothly.
    [0029] As shown in Figures 1 and 4, in real operation, the blank body floor panel is first transferred to the high speed roller track 4 by the high speed transport system 3, and positioned after the position adjustment made by the triaxial positioning fixing mechanism of the intelligent positioning units 5; then, the side panel instrument at the exit site of the tetrahedral rolling table 20 is transported to the support rail 13 of the sliding table 11 through a respective instrument switch riveter and the instrument switch transport rail 31, a
    11/12 sliding table 11 transfers the received side panel instrument to the side panel instrument positioning platform in the vertical direction, the side panel instrument positioning platform performs the last position adjustment and positioning on the side panel instrument , and then the positioning of the instrument panel and the floor panel of the bodywork is finished. The robotic welding system welds the floor panel and the side panel, and with this, the blank body welding process is finished. Finally, the side panel instrument positioning platform opens, and the side panel instrument retracts next to the slide table 11, and is attached to the instrument switching transport rail 31 again. The side panel instrument is sent back to the free site of the tetrahedral rolling table 20 under the action of the instrument switching riveter. At the same time, after the intelligent positioning units 5 open, the blank welded body is placed on the high speed roller belt 4, and transferred to the next machining site via the high speed transport system 3, and then, the blank body welding process is finished.
    [0030] Since seven different side panel instruments can be simultaneously transported on the two tetrahedral rolling tables, the instrument switching process can be carried out synchronously in the welding process. For example, when the system receives an instruction from the factory to use the type B vehicle, the system first identifies the type B vehicle instrument, and then determines the specific location to store the type B vehicle instrument and whether the type B vehicle is at the exit site for instrument switching, and at the same time, determine whether the other exit site is a free site. If not, the system launches an instruction for the tetrahedral rolling tables to turn the side panel instrument with the type B vehicle to one of the exit sites, and, at the same time, to rotate the free site.
    12/12 to the other exit site. The free site is used to receive the side panel instrument at work, and the side panel instrument for the type B vehicle is used as an auxiliary instrument for the next time. With this, the adjustment of the side panel instrument is completed, with no impact on the normal automatic welding process. Of course, if it is necessary to adjust the position of the two auxiliary side panel instruments, the instrument return rail and the free site at the exit site can also be used to adjust the position of the side panel instruments between the two tetrahedral rolling tables, thus significantly increasing the flexibility and convenience of using the flexible side panel positioning and switching system, and truly performing a flexible assembly of a multiveicular co-production line.
