Detailed Embodiment

[0028] The following will be combined with the drawings and embodiments to detail the implementation manner of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0029] Such as Figures 1 - 5As shown in the figure, the welding tooling for an automotive seat bracket includes a workbench 1 and a pressing mechanism used in conjunction with the workbench 1. The pressing mechanism can limit and fix the bracket to be welded located on the workbench 1. The pressing mechanism includes four first electric telescopic rods 2 and four second electric telescopic rods 3. Both the first electric telescopic rod 2 and the second electric telescopic rod 3 are equipped with a pushing block 8 through a top rod 14. Below the pushing block 8, there is a pressing arm 9 respectively. The pressing arm 9 is threadedly engaged with a pressing block 11 and a pressing head 13 for product pressing and limiting through a double screw rod 15 or a threaded column 16 respectively. The first electric telescopic rod 2 and the second electric telescopic rod 3 can push out the top rod 14 by telescoping, so that the position of the pressure application point at the bottom of the pushing block 8 rotatably connected to the top rod 14 changes. Furthermore, the position of the pressure application of the pressing arm 9 below it can be changed. In this way, the pressing arm 9 can press or release the bracket through the pressing block 11 or the pressing head 13. On one side of the pressing arm 9 located on the first electric telescopic rod 2, there is a limit connecting plate 10. The double screw rod 15 passes through the limit connecting plate 10 and is threadedly engaged with it. The lower half of the double screw rod 15 is threadedly engaged with the pressing block 11. The width of the pressing block 11 is greater than that of the pressing arm 9. The double screw rod 15 can be rotated, so that the pressing block 11 can be adjusted up and down on it. When the pressing block 11 is adjusted to a certain position, it can abut against the surface of the pressing arm 9, and then its position can be limited and fixed. In this way, the first electric telescopic rod 2 can use the pressing block 11 to press the bracket. On one side of the pressing arm 9 located on the second electric telescopic rod 3, there is an upper fixing plate 17 and a lower fixing plate 18. The threaded columns 16 are threadedly engaged with both the upper fixing plate 17 and the lower fixing plate 18. The threaded columns 16 pass through the upper fixing plate 17 and the lower fixing plate 18. The pressing head 13 is fixedly arranged at one end of the threaded column 16. The threaded column 16 is threadedly engaged with a nut. Similarly, the upper fixing plate 17 and the lower fixing plate 18 can be installed on the pressing arm 9 located on the second electric telescopic rod 3, so that the threaded column 16 can be threadedly engaged with both of them from the lower end. When the upper half of the threaded column 16 is exposed, a nut can be installed for it to limit the position of the threaded column 16. Then the second electric telescopic rod 3 can use the pressing head 13 to press the bracket.

[0030] The workbench 1 includes a clamping base 102, a limiting base 103, and a connecting base 101 for placing the first electric telescopic rod 2 and the second electric telescopic rod 3. One end of the clamping base 102 is clamped and connected with a seat bracket 5. The limiting base 103 is used for placing the flat piece of the seat bracket 5. The pressing block 11 and the pressing head 13 are respectively located above the limiting base 103 and the clamping base 102. The seat bracket 5 to be processed can be placed in a limited way through the clamping base 102 and the limiting base 103. At the same time, the heights of each clamping base 102 and the limiting base 103 are different to adapt to seat brackets 5 of a fixed model. At the same time, the first electric telescopic rod 2 and the second electric telescopic rod 3 can use the connecting base 101 to increase their own heights, so that each pressing block 11 and the pressing head 13 can be located above the clamping base 102 and the limiting base 103.

[0031] Further, as Figure 2 and Figure 3 shown, the ejector rod 14 is fixedly connected to the output ends of the first electric telescopic rod 2 and the second electric telescopic rod 3. A connecting screw rod 7 is screwed on the side of the ejector rod 14 away from the output end. The ejector rod 14 is screwed with an auxiliary rotating rod 6 and a pushing block 8 through the connecting screw rod 7. The auxiliary rotating rods 6 are located on the opposite sides of the upper half of the pushing block 8. One end of the auxiliary rotating rod 6 away from the connecting screw rod 7 is rotatably connected to an adapter base 12 through a rotating shaft. The adapter base 12 and the connecting base 101 are screwed together by bolts. One end of the pressing arm 9 is rotatably connected to the adapter base 12 through a rotating shaft. When the first electric telescopic rod 2 and the second electric telescopic rod 3 are turned on, a pushing force can be applied to the ejector rod 14, so that the ejector rod 14 can push the pushing block 8. However, the lower half of the pushing block 8 rotates with the pressing arm 9. Therefore, only the upper half of the pushing block 8 swings when it is subjected to the pushing force, and its lower half presses the pressing arm 9, so that the pressing arm 9 can press and limit or release the seat bracket 5 through the pressing block 11 or the pressing head 13. At the same time, the upper half of the auxiliary rotating rod 6 abuts against the two sides of the upper half of the pushing block 8, so that the auxiliary rotating rod 6 can play a certain auxiliary role after the pushing block 8 is stressed, avoiding the upper half of the pushing block 8 from not swinging smoothly. Moreover, the adapter base 12 can not only provide rotation for the auxiliary rotating rod 6 and the pressing arm 9 through the rotating shaft, but also provide a gap for position adjustment for the pressing arm 9. And the staff can also remove 8 and 6 by disassembling 7. Among them, the middle part of 7 can be smooth, so that 8 can rotate.

[0032] Further, as Figures 2 - 4As shown in the figure, a connecting bracket is fixedly arranged at one end of the connecting base 101. The connecting bracket is threadedly connected to the first electric telescopic rod 2 and the second electric telescopic rod 3 through threaded connecting rods. The height of each connecting base 101 is different. When the orientation of the first electric telescopic rod 2 or the second electric telescopic rod 3 needs to be adjusted, the staff can disassemble the threaded connecting rod, so that the first electric telescopic rod 2 or the second electric telescopic rod 3 can rotate inside the two opposite connecting brackets, thereby facilitating the staff to adjust the orientation of the first electric telescopic rod 2 or the second electric telescopic rod 3. At the same time, the threaded connecting rod can also be disassembled to separate the first electric telescopic rod 2 or the second electric telescopic rod 3 from the connecting base 101. At the same time, the connecting bases 101 with different heights can make the first electric telescopic rod 2 and the second electric telescopic rod 3 adapt to the heights of the clamping base 102 and the limiting base 103.

[0033] Further, as Figure 1 and Figure 5 shown in the figure, the workbench 1 further includes a mounting base 104 and a fixing base 4. One end of the mounting base 104 away from the workbench 1 is clamped and connected with a welding bracket 501. One end of the fixing base 4 is fixedly provided with a limiting plate 401 for limiting the position of the welding bracket 501. Through the mounting base 104, the welding bracket 501 to be welded to the seat bracket 5 can be clamped and placed, so as to facilitate the staff to weld the two. At the same time, the staff can pull the limiting plate 401, so that the pressing plate arranged on the limiting plate 401 can be used to press and limit the welding bracket 501.

[0034] Furthermore, as Figure 1 shown in the figure, one end of each of the connecting base 101, the clamping base 102, the limiting base 103 and the mounting base 104 is magnetically attracted to the workbench 1 through strong magnetism. By means of magnetic attraction, the positions of the connecting base 101, the clamping base 102, the limiting base 103 and the mounting base 104 can be adjusted, so as to adapt to different models of seat brackets 5.

[0035] As Figures 1 - 5 shown in the figure, the principle of the automotive seat bracket welding tooling provided in this embodiment is as follows:

[0036] The first electric telescopic rod 2 and the second electric telescopic rod 3 can push out the ejector rod 14 by telescoping, so that the position of the pressure application point at the bottom of the ejecting block 8 rotatably connected to the ejector rod 14 changes. Furthermore, the position of the pressure application on the pressing arm 9 below it can be changed. In this way, the pressing arm 9 can press or release the frame body through the pressing block 11 or the pressing head 13. At the same time, the double screw rod 15 can be rotated, so that the pressing block 11 can be adjusted up and down on it. When the pressing block 11 is adjusted to a certain position, it can abut against the surface of the pressing arm 9, and then its position can be limited and fixed. In this way, the first electric telescopic rod 2 can use the pressing block 11 to press the frame body. Similarly, a fixed plate 17 and a lower fixed plate 18 can be installed on the pressing arm 9 located on the second electric telescopic rod 3, so that the threaded column 16 can be connected to both of them by screwing in from the lower end. When the upper half of the threaded column 16 is exposed, a nut can be installed on it to limit the position of the threaded column 16. Then, the second electric telescopic rod 3 can use the pressing head 13 to press the frame body.
