System performs.The structure and function of used each component can refer to previous embodiment in the present embodiment.
In assembling, two ends floor can be individually positioned on two end floor supporting devices first, then again will
Two side bars are individually positioned in the side bar support device of chassis assembling framework both sides, finally hang in middle floor, and welded.
Specifically, can the adjustment of all parts position and welding be realized by turnover device.It, can be according in welding
By the intermediate sequence to both sides, the junction of intermediate side bar and middle floor is welded, then the end floor to both sides first
Junction and end floor and the junction of side bar between middle floor are welded, and can ensure chassis total quality.
Further, before each junction on opposite end floor, side bar and middle floor is welded, the vehicle bottom
Rack-mounted method of completing the square can also include：Amount of deflection is applied to the part contacted in the side bar with the middle floor.
A part for the side bar is contacted with middle floor, and another part is contacted with end floor.In the present embodiment, need to apply
Amount of deflection is that part contacted in side bar with the middle floor, and the another part contacted with the end floor does not need to apply
Add amount of deflection.
Wherein, amount of deflection is applied to the part contacted in the side bar with the middle floor, can specifically included：On the side
Increase height adjustment pad between side bar supporting block and side bar in beam support device, to realize the application of opposite side beam deflection.
Due to the requirement of vehicle carrying amount of deflection, need to realize amount of deflection in ship type chassis, in order to realize the amount of deflection of ship type chassis
It is required that needing to apply vertical deflection value in entire chassis, specific implementation position is the side bar supporting block institute in side bar support device
In position, implementing direction is longitudinal direction, implements the longitudinal length that length is middle floor.The size of the deflection value of application can be according to reality
Border needs and the material and size of chassis each component are set.Height adjustment pad in side bar supporting block is bonded journey with side bar

Even on height adjustment pad can not be increased in most central side bar supporting block.After the completion of assembling, chassis can be overturn
Come over, the amount of deflection for thereby realizing side bar middle section is larger, more smaller toward both sides amount of deflection.
Assuming that the side bar support device for needing to apply amount of deflection is per each 9 of side, successively referred to as supporting block 1,2,3 ..., 9,
Both sides totally 18.By applying the prefabricated amount of deflection in longitudinal direction in the side bar supporting block of side bar support device, entire chassis can be realized
The amount of deflection of frame.
Wherein, it is maximum with the deflection value applied at 5 corresponding center of supporting block in side bar, with continuous with the distance at center
Increase, the deflection value that the corresponding side bar of each supporting block of surrounding applies everywhere are also gradually reduced, in side bar with supporting block 1 and supporting block
Farthest with side bar centre distance at 9 corresponding two, the deflection value of application is also minimum, disclosure satisfy that the chassis after the completion of assembling
Amount of deflection demand.
Further, the method can also include：On the side of part for being used to support side bar and being contacted with the end floor
Pressing device is installed in beam support device.The pressing device is used to compress that contacted with the end floor in side bar
Point.
It further, can also be described after each junction on opposite end floor, side bar and middle floor is welded
The assembling partition wall and edge sealing between floor and the middle floor are held, and the partition wall and edge sealing are welded, improves chassis
Quality.
Floor underframe for vehicle assembly method provided in this embodiment, by successively by the end floor of chassis, side bar and middle floor,
It places on end floor supporting device, side bar support device and chassis assembling framework respectively, and the end of side bar is made to fall into end ground
The overlap joint interface of plate, middle floor are assembled with side bar grafting, facilitate each connection on direct opposite end floor, side bar and middle floor
Place is welded, and meets the matching requirements of ship type chassis, effectively increases efficiency of assembling and assembling quality.
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
