The connecting member has a connecting end connected to the Z-axis endless adjustment structure and a follow-up end located outside the X-axis endless adjustment structure. The positioning support member is provided on the follow-up end, so that the cab bottom plate placed on the positioning support member can be avoided from the Z-axis endless adjustment structure. The X-axis endless adjustment structure is used to drive the Y-axis endless adjustment structure to move along the X-axis. The Y-axis endless adjustment structure is used to drive the Z-axis endless adjustment structure to move along the Y-axis.

[0054] It should be noted that the follow-up end located outside the X-axis endless adjustment structure 2 means that the overhead projection of the follow-up end is located outside the X-axis endless adjustment structure 2.

[0055] Using the white body flexible positioning support device in the present application, a plurality of white body flexible positioning support devices are respectively installed on both sides of the clamp BASE plate, and then the floor of the cab is placed above the plurality of white body flexible positioning support devices, so that the plurality of positioning support members 6 respectively extend into the plurality of positioning holes pre-set on the cab floor, so as to realize the positioning and support of the cab floor.

[0056] When the different cab bottoms are positioned and supported, according to the preset positioning holes on the cab bottom plate, the X-axis endless adjusting structure 2 adjusts the Y-axis endless adjusting structure 3, so that the Y-axis endless adjusting structure 3 drives the Z-axis endless adjusting structure 4, the connecting member 5 and the positioning and supporting member 6 to move along the X-axis to the required position, the Y-axis endless adjusting structure 3 adjusts the Z-axis endless adjusting structure 4, so that the Z-axis endless adjusting structure 4 drives the connecting member 5 and the positioning and supporting member 6 to move along the Y-axis to the required position, and the Z-axis endless adjusting structure 4 adjusts the connecting member 5, so that the connecting member 5 drives the positioning and supporting member 6 to move along the Z-axis to the required position, so that the positioning and supporting member 6 can position and support the cab bottom plate of different vehicle models, thereby increasing the flexibility of the flexible body-in-white positioning and supporting device.

[0057] At the same time, the phenomenon that the flexible body-in-white positioning and supporting device needs to be replaced or a new production line needs to be built when the cab bottom plate of different vehicle models is positioned and supported is avoided, so that the cabs of multiple vehicle models can be produced in line, thereby reducing the production cost of light trucks.

[0058] In addition, since the Z-axis endless adjusting structure 4 is arranged at the side of the Y-axis endless adjusting structure 3, the positioning and supporting member 6 can move in a larger range in a limited space, thereby further increasing the flexibility of the flexible body-in-white positioning and supporting device, so that the flexible body-in-white positioning and supporting device can position and support the cab bottom plate of more vehicle models.

[0059] In addition, since the Z-axis endless adjusting structure 4 is arranged at the side of the Y-axis endless adjusting structure 3, the positioning and supporting member 6 can move in a larger range in a limited space, thereby further increasing the flexibility of the flexible body-in-white positioning and supporting device, so that the flexible body-in-white positioning and supporting device can position and support the cab bottom plate of more vehicle models.

In other embodiments, the positioning and supporting member 6 can also be a positioning pin or other structure that can extend into the preset positioning hole of the cab bottom plate.

[0061] In a preferred embodiment, referring to Figure 3 , Figure 8 and Figure 9The positioning support member 6 has a fixed section connected to the connecting member 5 and a positioning section capable of being penetrated through the cab floor, the fixed section is provided with a mounting plate 61, the mounting plate 61 is provided with a proximity switch 611 with the detection end facing upward.

[0062] Since the mounting plate 61 is provided with the proximity switch 611, the cab floor can be detected whether it is in place or not, so that the next processing procedure can be carried out, and the phenomenon that some of the positioning support members 6 of the flexible positioning support device for the body-in-white do not support the cab floor and the next processing procedure is carried out can be avoided, so that the safety during the production of the cab is increased.

[0063] It can be understood that the cylinder body of the pin-cylinder constitutes the fixed section, the piston rod of the pin-cylinder constitutes the positioning section, and after the proximity switch 611 detects that the cab floor is installed in place, the pin-cylinder clamps the cab floor.

Since the first transmission block 23 is threadedly connected with the first lead screw 22, and the first transmission block 23 is fixedly connected with the Y axis stepless adjustment structure 3, the first transmission block 23 moves along the axial direction of the first lead screw 22 under the action of the rotation of the first lead screw 22, so as to realize the adjustment of the body-in-white flexible positioning support device on the X axis. Furthermore, by arranging the first servo motor 24, the first lead screw 22 and the first transmission block 23, the body-in-white flexible positioning support device can be steplessly adjusted on the X axis, so as to ensure the flexibility of the body-in-white flexible positioning support device.
