DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] In the embodiment, it is given by Figure 1 A welding fixture for the rear load floor of an automobile, optionally but not limited to including: a load-bearing main body 1;

[0038] A first adjustment mechanism 2, arranged on the load-bearing main body 1, for laterally adjusting the rear load floor;

[0039] A second adjustment mechanism 3 arranged on the first adjustment mechanism 2, which includes two cylinders 33, symmetrically arranged on the first adjustment mechanism 2; a sliding plate 36, arranged between the output ends of the two cylinders 33;

[0040] An adsorption mechanism 4, arranged on the upper end surface of the sliding plate 36, for adsorbing and limiting the rear load floor.

[0041] In this embodiment, a welding fixture for the rear load floor of an automobile according to the present invention is given. By placing the rear load floor to be welded on the adsorption mechanism 4, the adsorption mechanism 4 will adsorb the rear load floor, and then the first adjustment mechanism 2 can drive the rear load floor to perform lateral adjustment, and the second adjustment mechanism 3 can drive the rear load floor to perform longitudinal adjustment, so that when the rear load floor is welded to the vehicle frame, it is ensured that the rear load floor can be better aligned with the vehicle frame, avoiding the need to re-clamp the rear load floor and affecting the welding efficiency of the rear load floor.

[0042] More specifically, as Figure 1 shown, an installation groove 11 is formed on the load-bearing main body 1.

[0043] Furthermore, as Figure 2 shown, the first adjustment mechanism 2 in the preferred embodiment of the present invention includes an installation sleeve 21, arranged inside the installation groove 11; a guide rod 22, arranged inside the installation sleeve 21; a servo motor 23, arranged outside the installation sleeve 21; a lead screw 24, arranged at the output end of the servo motor 23; and a moving block 25, arranged outside the lead screw 24.

[0044] Furthermore, the inner side of the moving block 25 is threadedly connected to the outside of the lead screw 24, and the moving block 25 is also slidably arranged outside the guide rod 22.

[0045] More specifically, one end of the lead screw 24 away from the servo motor 23 is rotatably arranged inside the mounting sleeve 21, so that the stability of the lead screw 24 is better when it rotates.

[0046] In this embodiment, multiple preferred embodiments of the first adjustment mechanism 2 are given. The servo motor 23 drives the lead screw 24 to rotate. The rotating lead screw 24 drives the moving block 25 to move. Since the moving block 25 also slides outside the guide rod 22, the moving block 25 will not rotate with the lead screw 24. In this way, the moving block 25 moves horizontally, thereby adjusting the horizontal position of the second adjustment mechanism 3.

[0047] Furthermore, as Figures 2 - 3 shown, in the preferred embodiment of the present utility model, the second adjustment mechanism 3 includes a mounting plate 31 arranged on the upper end surface of the moving block 25, and two cylinders 33 are symmetrically arranged outside the mounting plate 31; a sliding groove 32 is opened on the mounting plate 31, and a sliding plate 36 is located in the sliding groove 32; two T-shaped sliding grooves 34 are symmetrically opened inside the sliding groove 32; two T-shaped sliding blocks 35 are symmetrically arranged outside the sliding plate 36.

[0048] More specifically, the two T-shaped sliding blocks 35 are also respectively slidably arranged in the two T-shaped sliding grooves 34.

[0049] In this embodiment, multiple preferred embodiments of the second adjustment mechanism 3 are given. By setting the two cylinders 33, the sliding plate 36 can move longitudinally, thereby adjusting the longitudinal position of the adsorption mechanism 4, ensuring that the rear load floor on the adsorption mechanism 4 can be accurately docked with the vehicle frame, avoiding the need to clamp the rear load floor multiple times to adjust the position of the rear load floor. At the same time, the sliding plate 36 slides in the two T-shaped sliding grooves 34 through the T-shaped sliding blocks 35 on both sides, so that the sliding plate 36 has better stability when sliding.

[0050] Furthermore, as Figure 5 shown, in the preferred embodiment of the present utility model, the adsorption mechanism 4 includes a mounting frame 41 arranged on the upper end surface of the sliding plate 36; four electric push rods 42 are symmetrically arranged in two groups at the lower end surface of the mounting frame 41; four connecting plates 43 are respectively arranged at the output ends of the four electric push rods 42; a vacuum suction cup 44 is arranged on the upper end surface of the connecting plate 43.

[0051] Preferably, the number of vacuum suction cups 44 arranged on the upper end surfaces of the four connecting plates 43 is several.

[0052] In this embodiment, multiple preferred embodiments of the adsorption mechanism 4 are given. By placing the rear load floor to be welded on the upper end surfaces of the four connecting plates 43, the vacuum suction cups 44 on the connecting plates 43 will adsorb the rear load floor, thereby fixing the rear load floor and ensuring its stability during welding.

[0053] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.
