[0027] Example 1:

[0028] like Figure 1-4 This invention provides a welding positioning fixture, including a welding worktable 1, a fixing plate 2, a fixing frame 5, a first baffle 3, and a second baffle 4. A support assembly is provided on the bottom surface of the welding worktable 1, and the fixing plate 2 is provided on the surface of the welding worktable 1. The fixing plate 2 is detachably connected to the welding worktable 1. The first baffle 3 and the second baffle 4 are respectively provided on the left and right sides and the front and rear sides of the surface of the fixing plate 2. The fixing frame 5 is provided on the surface of the fixing plate 2 outside the first baffle 3 and the second baffle 4. An adjustment assembly is provided on the outer side of the first baffle 3 and the second baffle 4, allowing the first baffle 3 and the second baffle 4 to slide on the surface of the fixing plate 2. The adjustment assembly includes a sleeve 21, a screw 22, and a handle 23. The sleeve 21 is fixed to the side of the first baffle 3 and the second baffle 4, and a threaded hole is provided on the surface of the fixed frame 5 at the position corresponding to the sleeve 21. The screw 22 is provided inside the sleeve 21, and the other end of the screw 22 passes through the threaded hole and is fixedly connected to the handle 23. The user can rotate the handle 23 through the threaded connection between the screw 22 and the threaded hole, thereby rotating the screw 22 and adjusting the position of the first baffle 3 and the second baffle 4 on the surface of the fixed plate 2, so that the welding cavity 9 formed by the two first baffles 3 and the two second baffles 4 can change according to the different welding workpieces.

[0029] A first sliding plate 6 and a second sliding plate 7 are respectively provided at both ends inside the first baffle 3 and the second baffle 4. The first sliding plate 6 and the second sliding plate 7 are slidably connected to the first baffle 3 and the second baffle 4, respectively. Through the cooperation of the first sliding plate 6 and the second sliding plate 7, the two first baffles 3 and the two second baffles 4 can form a closed welded cavity 9 regardless of their position on the surface of the fixed plate 2. Slotted through holes 13 are provided at both ends of the top surface of the first baffle 3 and the second baffle 4. Sleeve rods 14 are provided upwardly at the positions of the first sliding plate 6 and the second sliding plate 7 corresponding to the positions of the slotted through holes 13. A sliding rod 15 is provided inside the sleeve rod 14 and is slidably connected to the sleeve rod 14. The other end of the sliding rod 15 passes through the slotted through hole 13 and is fixedly connected to the circular plate 16. The slotted through hole 13 is located on the surface of the first baffle 3 and the second baffle 4. The circular plate 16 has slots 17 on both sides. A fixing block 18 is set on the bottom of the circular plate 16 corresponding to the slot 17. A first magnetic sheet 19 is bonded to the bottom of the fixing block 18. A second magnetic sheet 20 is bonded to the bottom of the slot 17. After the positions of the first baffle 3 and the second baffle 4 are adjusted, the user can control the extension of the first slide plate 6 and the second slide plate 7 by sliding the circular plate 16, so that the two first baffles 3 and the two second baffles 4 form a complete sealed welding cavity 9. After the first slide plate 6 and the second slide plate 7 have slid, the user can press down the circular plate 16 to make the sliding rod 15 extend into the sleeve rod 14 and make the first magnetic sheet 19 on the bottom of the fixing block 18 and the second magnetic sheet 20 at the bottom of the slot 17 magnetically connected, thereby fixing the positions of the first slide plate 6 and the second slide plate 7 and forming a stable welding cavity 9.

[0030] A first partition 10 and a second partition 11 are respectively provided inside the welding cavity 9. The first partition 10 and the second partition 11 are perpendicularly connected to each other. A first extension plate 24 and a second extension plate 25 are respectively provided at both ends of the first partition 10 and the second partition 11, and are slidably connected to the first partition 10 and the second partition 11. A retaining plate 26 is horizontally provided at the top of both ends of the first extension plate 24 and the second extension plate 25. A retaining groove 27 is provided at the top of the inner side of the first baffle 3 and the second baffle 4 corresponding to the position of the retaining plate 26. After the welding cavity 9 is formed, the user can pull the first extension plate 24 and the second extension plate 25 out from inside the first partition 10 and the second partition 11 to make the first... The card plates 26 at the top of both ends of the extension plate 24 and the second extension plate 25 are embedded in the corresponding slots 27 on the inner sides of the first baffle 3 and the second baffle 4, so that the first partition 10 and the second partition 11 can divide the welding cavity 9 into four core cavities 12. After welding is completed, there is a certain gap around the workpiece, which facilitates the subsequent injection of potting compound and eliminates internal voids. The heat dissipation coefficient of the potting compound after curing is greater than that of the film, which facilitates the heat dissipation of the workpiece. Furthermore, the first slide plate 6 has plate slots 8 at both ends. The plate slots 8 do not penetrate the first slide plate 6. During welding, the user can put the electrode plate into the plate slot 8 so as not to affect the normal welding work.

[0031] Example 2:

[0032] like Figure 5-6 In this embodiment, a protective cover 28 is provided on the surface of the welding workbench 1. A plurality of limiting protrusions 34 are provided at equal intervals on the bottom surface of the protective cover 28, and a plurality of limiting grooves 35 are correspondingly provided on the surface of the welding workbench 1. The protective cover 28 and the welding workbench 1 are detachably connected by the cooperation of the limiting protrusions 34 and the limiting grooves 35, which facilitates use. Ventilation holes 29 are provided on both sides of the protective cover 28, and an air-cooling component is provided on the top of the protective cover 28. The air-cooling component includes a fan 33, a rotating shaft 32 and a drive motor 31. The drive motor 31 drives the rotating shaft 32 to rotate, thereby causing the fan 33 to rotate. The fan 33 cools the welded workpiece, further accelerating its cooling and heat dissipation speed and improving efficiency.

[0033] Example 3:

[0034] like Figure 7 In this embodiment, the support assembly located on the bottom surface of the welding workbench 1 includes a vertical rod 36, a column 37, and a support foot 38. The vertical rod 36 is vertically arranged, and its top end is fixedly connected to the bottom surface of the welding workbench 1. A column 37 is provided on the outer side of the bottom end of the vertical rod 36, and the vertical rod 36 is threadedly connected to the column 37. A support foot 38 is fixedly connected to the bottom end of the column 37. When using the workbench, the user can adjust the height of the welding workbench 1 by rotating the column 37, which makes it more convenient for the user to use.

[0035] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing common knowledge technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
