[0042] Combine the following Figures 1 to 4 The floor seat positioning and installation device of the utility model is described. The floor seat positioning and installation device can realize the positioning of the mounting seat on the floor of the rail vehicle, which is convenient for welding the mounting seat. The floor of the rail vehicle is usually approximately a rectangular structure, and one side thereof is provided with a plurality of slide grooves extending along the length direction, and a plurality of floor seats are welded in each slide groove. For example, there are 8 slide grooves, and 21 floor seats need to be welded in each slide groove. The mounting seats in each slide groove need to be aligned horizontally. Although the slide groove can position the floor seat horizontally, it cannot achieve longitudinal positioning. Therefore, when welding the floor seat, the floor seat needs to be pressed in the positioning position for positioning welding, and then welding is performed. This causes the operator to spend a lot of energy on operations such as positioning, pressing, and positioning welding of the floor seat one by one. In order to solve this problem, the utility model provides a floor seat positioning and installation device. The floor seat positioning and installation device provided by the utility model is exemplarily introduced below.

[0043] Combination Figure 1 and Figure 2According to the floor seat positioning and installation device provided in this embodiment, it includes a crossbeam 100, a pair of adsorption mechanisms 200 and a plurality of clamps 300. The pair of adsorption mechanisms 200 are respectively disposed at both ends of the crossbeam 100, and the adsorption mechanisms 200 are suitable for being adsorbed and fixed to the floor. The plurality of clamps 300 are arranged at intervals along the crossbeam 100, and the plurality of clamps 300 are suitable for switching between a downward pressing state and a raised state, and the pressure rods 301 of the plurality of clamps 300 are located on the same side of the crossbeam 100.

[0044] Specifically, a pair of adsorption mechanisms 200 are symmetrically arranged about the mid-vertical plane of the beam 100. When the pair of adsorption structures are adsorbed on the floor, the beam 100 is parallel to the floor. The multiple clamps 300 on the beam 100 are arranged along the length direction of the beam 100. Therefore, it is only necessary to position the two ends of the beam 100 to achieve the positioning of the multiple clamps 300. After the positioning of the beam 100 is completed, the floor seats at the corresponding positions can be respectively compressed by the multiple clamps 300 to achieve the positioning and clamping of the floor seats. At this time, welding can avoid the movement of the floor seats. Therefore, through the floor seat positioning and installation device of the embodiment of the utility model, the positioning and clamping of multiple floor seats can be quickly achieved to facilitate welding. It is also possible to omit the welding and grinding processes of the positioning welding, and directly perform welding, further reducing the workload of the operators and improving production efficiency.

[0045] The presser 300 in this embodiment can be flexibly designed according to the number of floor seats in the same row of the floor, and is not specifically limited here.

[0046] In some embodiments, the floor seat positioning and installation device further includes a first locking structure, and the presser 300 is adapted to be adjusted along the length direction of the cross beam 100 and positioned by the first locking structure. Thus, adaptive adjustment can be conveniently performed according to the different spacings of the floor seats in different vehicle models, meeting the positioning requirements of the floor seats of different vehicle models, and having better applicability.

[0048] Specifically, the first groove 101 extends along the length direction of the crossbeam 100 and penetrates the crossbeam 100 along the length direction of the crossbeam 100. The first groove 101 forms an opening on the upper side of the crossbeam 100, and the opening width of the first groove 101 on the upper side of the crossbeam 100 is smaller than the width inside the first groove 101 to form a T-shaped groove structure. The head of the first bolt 104 is located in the first groove 101, and the screw rod portion passes through the opening of the first groove 101 on the upper side of the crossbeam 100, thereby, the crossbeam 100 forms an axial limit for the first bolt 104. The base 308 of the clamp 300 is located on the upper side of the crossbeam 100, and is provided with a through hole for the screw rod portion of the first bolt 104 to pass through. The first positioning nut is located on the upper side of the base 308 of the clamp 300 and is threadedly connected with the first bolt 104. When the first positioning nut is tightened, the clamp 300 can be fixed, and the position of the clamp 300 can be adjusted by rotating the first positioning nut in the opposite direction. The first groove 101 penetrates the cross beam 100 , and can facilitate the first bolt 104 to slide in or out from both ends of the cross beam 100 , thereby realizing the disassembly and assembly of the clamp 300 , and further realizing the quantity adjustment according to the quantity of floor seats in different vehicle models.

[0049] The plurality of first bolts 104 and the first positioning nuts in the first locking structure are arranged at intervals along the length direction of the crossbeam 100, and the plurality of first bolts 104 and the first positioning nuts simultaneously fix the base 308 of the presser 300 to improve stability. For example, as shown in the figure, the first locking structure includes two first bolts 104 and two first positioning nuts, and the two first bolts 104 and the two first positioning nuts simultaneously fix the presser 300.

[0050] In some embodiments of the present invention, the floor seat positioning and installation device further includes a positioning member 400, which is disposed on the cross beam 100. The positioning member 400 includes a plurality of positioning plates 402, which are vertically disposed on the lower side of the cross beam 100 and are evenly spaced along the length direction of the cross beam 100. The plurality of positioning plates 402 correspond to the plurality of pressers 300. The positioning plates 402 can be used to abut against the floor seat, thereby limiting the floor seat in the longitudinal direction.

[0051] The positioning member 400 further includes a fixing plate 401 , which is fixed to the lower side of the crossbeam 100 , and a positioning plate 402 is vertically fixed to the fixing plate 401 .

[0052] In an optional manner, the fixing plate 401 extends along the length direction of the beam 100, and a plurality of positioning plates 402 are arranged on the same fixing plate 401.

[0055] Specifically, the lower side of the cross beam 100 is provided with a second groove 102, and the second groove 102 is a T-shaped groove. The second groove 102 forms an opening on the lower side of the cross beam 100, and the width of the opening is smaller than the inner width of the second groove 102, so as to form a T-shaped groove structure. The second groove 102 extends along the length direction of the cross beam 100 and penetrates the cross beam 100. The second locking structure includes a plurality of second bolts 106 and second nuts 107 corresponding to the plurality of second bolts 106. The heads of the second bolts 106 are located in the second groove 102, and the screw parts of the second bolts 106 pass downward through the openings of the second groove 102. A through hole is provided on the fixing plate 401 of the positioning member 400, and the second bolts 106 are penetrated through the through holes on the fixing plate 401. The second nuts 107 are located on the lower side of the fixing plate 401 and threadedly cooperate with the second bolts 106 to install the fixing plate 401 on the lower side of the cross beam 100.

[0056] In this embodiment, since the fixing plate 401 and the cross beam 100 are fixed by bolts, when it is necessary to weld the floor seat of different models, the positioning member 400 can be easily removed and replaced with a size suitable for the model, and the position of the positioning member 400 can also be easily adjusted along the cross beam 100.
