[0002] Tractor flat floor seat frame frame such as Figure 3 As shown, positioning this structure during welding is difficult, which can easily lead to dimensional deviations in the welded seat frame, affecting subsequent assembly processes. Furthermore, when welding manually by hand, the workpiece lacks stability and is prone to shaking during the welding process, affecting welding quality and causing defects such as uneven welds, incomplete welds, and missed welds, thus reducing the product yield. Moreover, after welding, the workpiece is difficult to lift due to limitations in some tooling structures, impacting overall production efficiency. Therefore, this application proposes a welding fixture for a tractor flat floor seat frame to solve these problems. Summary of the Invention

[0003] The technical problem to be solved by this application is to overcome the existing defects and provide a welding fixture for the frame of a tractor flat floor seat, which can effectively solve the problems in the background art.

[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0014] Please see Figure 1-4 This application provides a technical solution for welding fixtures for tractor flat floor seat frames: a welding fixture for tractor flat floor seat frames includes a base plate 1 and a side plate 2, with two base plates 1 and two side plates 2, and two connecting plates 3 are provided between the two base plates 1.

[0015] Furthermore, an adjusting baffle 11 is provided on the base plate 1. The adjusting baffle 11 includes a screw 12, an internal hexagonal head 13, a stop block 14, and a slide groove 15. The slide groove 15 is provided on the base plate 1. The screw 12 is rotatably connected in the slide groove 15. One side of the screw 12 is connected to the internal hexagonal head 13. The internal hexagonal head 13 is rotatably connected to one side of the base plate 1. The outer side of the screw 12 is connected to the stop block 14 through a nut.

[0016] Specifically, the stop 14 can slide within the slide groove 15, and the stop 14 can limit the end of the square support column. By rotating the internal hexagon head 13, the screw 12 can be rotated, thereby adjusting the position of the stop 14.

[0017] Two base plates 1 are connected to the connecting plate 3 by fasteners. Side plates 2 are welded to the base plates 1, and the tilt angle of the side plates 2 is consistent with the tilt angle of the tilting parts on the flat floor seat frame workpiece.

[0018] One of the connecting plates 3 is equipped with an adjustment limit group, and the outer side of the base plate 1 is equipped with no less than two positioning blocks 4. An adjustment fixing plate 5 is provided on the side of the base plate 1 away from the positioning blocks 4.

[0019] Furthermore, the adjusting fixing plate 5 includes a fixing plate 6, a first nut 7 and a first bolt 8. The first nut 7 is provided on one side of the fixing plate 6, and the first bolt 8 is threadedly connected inside the first nut 7.

[0020] Specifically, the fixing plate 6 is welded to the base plate 1. The fixing plate 6 is installed on the base plate 1 away from the positioning block 4, and the fixing plate 6 and the two positioning blocks 4 form a triangular fixation to prevent the square support column from shaking during the welding process, which could lead to welding errors.

[0021] A side plate 2 is inclinedly provided on the outer side of the base plate 1, and a clamping plate 9 is installed on the side plate 2.

[0022] Furthermore, the clamping plate 9 is L-shaped, and a second nut 22 is provided on the lower surface of the clamping plate 9. A second bolt 23 is connected to the inside of the second nut 22 by a thread. The end of the second bolt 23 is polished smooth to avoid damaging the side column.

[0023] Specifically, the clamping plate 9 is welded to the side plate 2, and a limiting space is formed between the clamping plate 9 and the side plate 2, so as to position the side column of the flat floor seat frame. By rotating the second bolt 23, the second bolt 23 can be moved toward the side column to fix the side column to the side plate 2.

[0024] A rotating mounting assembly 10 is provided on one side of the upper surface of the side plate 2.

[0025] Furthermore, the rotating mounting assembly 10 includes a support plate 16, a movable plate 17, a pressure plate 18, and a mounting plate 19. The support plate 16 is mounted on the upper surface of the side plate 2. The movable plate 17 is rotatably connected inside the support plate 16. One side of the movable plate 17 is connected to the pressure plate 18. Mounting plates 19 are provided on both sides of the pressure plate 18. Mounting through holes are provided on the mounting plates 19.

[0026] Specifically, the mounting through holes on the mounting plate 19 are consistent with the holes on the connecting part of the flat floor seat frame, and the connecting part is fixed to the mounting plate 19 by bolts. The pressure plate 18 between the two mounting plates 19 contacts the side column, which makes it easier for workers to weld the connecting part to the side column.

[0027] After welding is completed, loosen the bolts of the fixed connection part, and then move the handle to make the movable plate 17, pressure plate 18 and mounting plate 19 rotate along the hinge point between the movable plate 17 and the support plate 16, so as to remove the mounting plate 19 from the connection part, thereby making it easier for workers to hoist the flat floor seat frame frame.

[0028] Furthermore, a handrail 20 is provided on the upper surface of the movable plate 17, and a limiting plate 21 is provided between the two support plates 16 to limit the rotation angle of the connecting plate, and the limiting plate 21 is provided on the lower surface of the movable plate 17.

[0029] like Figure 3 The flat floor seat frame mainly consists of two square support columns, side columns, connecting parts, and connecting shells. The square support columns can be placed on the base plate 1 and positioned by the positioning block 4. The adjusting fixing plate 5 fixes the square support columns. The side columns are positioned by the cooperation of the clamping plate 9 and the side plate 2, and are fixed by the second bolt 23 on the clamping plate 9. The connecting parts are installed on the side columns, and the connecting parts are limited and fixed by the rotating installation group 10, which facilitates the workers to weld the connecting parts and the side columns.

[0030] In use: First, adjust the position of the stop block 14. Insert the hex wrench into the internal hex head 13 and rotate the internal hex head 13 to rotate the screw 12, thereby adjusting the position of the stop block 14. Then, place the square support column on the base plate 1 and push it to the stop block 14. The side of the square support column contacts the positioning stop block 4. Rotate the first bolt 8 to move the first bolt 8 toward the square support column, thereby fixing the square support column to the positioning stop block 4 by the first bolt 8. Then, place the side column between the clamping plate 9 and the side plate 2, and fix the side column with the second bolt 23 on the clamping plate 9. The connecting part is fixed to the mounting plate 19 by bolts. The pressure plate 18 between the two mounting plates 19 contacts the side column, thereby facilitating the worker to weld the square support column, the side column and the connecting part.

[0031] After welding is completed, loosen the bolts of the fixed connection part, and then move the handle to make the movable plate 17, pressure plate 18 and mounting plate 19 rotate along the hinge point between the movable plate 17 and the support plate 16, so as to remove the mounting plate 19 from the connection part, thereby making it easier for workers to hoist the flat floor seat frame frame.
