[0014] Figure 2 This is a schematic diagram of the overall structure of an embodiment of the present application Figure 2 . DETAILED DESCRIPTION

[0015] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0016] The manual welding platform in this embodiment includes a column frame, a lifting structure and a welding platform structure. Figure 1 and Figure 2The structure of this application is described in detail.

[0017] The column frame 1 serves as the support for the entire structure and consists of two vertical columns 11, a guide frame 12 fixed to the vertical columns 11, and a movable base frame 13 located at the bottom of the two vertical columns 11. The guide frames 12 are fixed to both sides of the vertical columns 11 for connection to the welding platform structure. A through hole 111 is provided in the center of the vertical column 11.

[0018] The lifting structure 2 includes a lifting synchronization mechanism and a lifting power mechanism. Figure 2 As shown, the lifting synchronization mechanism includes two sets of synchronous wheels 211, two synchronous belts 212, and a set of synchronous shafts 213. Each set of synchronous wheels 211 is respectively mounted at the upper and lower ends of the same vertical column 11, and the two sets of synchronous wheels 211 are respectively mounted on different vertical columns 11. Each set of synchronous wheels 211 is connected by a synchronous belt 212. The synchronous shaft 213 is connected to the two synchronous wheels located at the lower ends of the two vertical columns. The lifting power mechanism 22 is connected to one of the synchronous wheels 211 at the lower end of one of the vertical columns to drive the rotation of each synchronous belt 212.

[0019] The welding platform structure 3 includes two groups of connecting blocks 31, a rotating frame 32, a positioning mechanism 33, a table 34 and a rotating power mechanism 35. Among them, the two groups of connecting blocks 31 are hollow frame structures, and holes 311 are provided on both sides of the connecting blocks 31. The guide frame 12 passes through the holes 311, so that the connecting blocks 31 can only move up or down along the guide frame 12. A tooth plate (not shown in the figure) is fixed to the inner side of the connecting block 31 by bolts, and a rack is provided on the synchronous belt 212, and the rack is engaged with the tooth plate. When the lifting power mechanism 22 rotates with the synchronous wheel 211, the synchronous belt 212 engages with the tooth plate in the connecting block 31, and then drives the connecting block 31 to move up or down along the guide frame. The two ends of the rotating frame 32 are connected to the two groups of connecting blocks 31 through a rotating rod 321 and a seat bearing 322. The rotating rod 321 passes through the through-hole 111 of the vertical post 11. The distal end of the rotating rod 321 is fixed to the connecting block 31 via a fixed shaft 323. The other end of the rotating rod 321 is connected to the bearing of a seated bearing 322. The seated bearing 322 is bolted to the rotating frame 32. As the rotating rod 321 rotates, the seated bearing 322 drives the rotating frame 32. The rotating frame 32 can rotate 360° relative to the connecting block 31, allowing adjustment to different welding surfaces. A table 34 is fixed to the rotating frame 32 to hold the material to be welded. A positioning mechanism 33 is located at one end of the rotating frame 32 to determine the rotation angle of the rotating frame 32. As shown in the figure, the positioning mechanism 33 is a circular disk with several adjustment holes 331. Positioning holes are provided on the corresponding columns 11. Positioning is achieved by positioning bolts inserted through the positioning holes in the columns 11 and the adjustment holes 331 in the circular disk. The rotating power mechanism 35 is fixed on a connecting block 31 and is connected to one of the rotating rods 321 . The rotating power mechanism 35 drives the connecting blocks 31 on opposite sides of the rotating frame 32 to rotate.

[0020] A pressing mechanism 4 is provided on the rotating frame 32 and is located above the table 34. The pressing mechanism 4 includes a rotating bracket 41 and a pressing member 42 fixed to the rotating bracket 41.

The fixing plate 421 is connected to the rotating bracket 41 and is vertically downward. The mounting plate 422 is locked to the surface of the fixing plate 421. The mounting plate 422 is provided with a connecting groove 4231 and a positioning ring 4232. The handle 423 is connected to the connecting groove 4231 via a connecting shaft. The top of the clamping member 423 is connected to the handle 423, and the bottom of the handle 423 is connected to the top of the connecting rod 425. The connecting rod 425 passes through the positioning ring 4232, and the bottom of the connecting rod 425 is connected to the corrugated pressing head 426. When the handle 423 is pressed downward, the clamping member 423 pushes the connecting rod 425 downward as the handle 423 moves downward, thereby pushing the corrugated pressing head 426 to press the material 5 to be welded. The corrugated pressure head 426 is screwed into the bottom of the connecting rod 425 through a screw, and can be adjusted to different heights to adapt to materials 5 to be welded with different curvatures.

[0022] The rotating bracket 41 includes a support rod 411, a locking block 412, and an arm 413. The locking block 412 is rotatably connected to the top of the support rod 411. It is connected to one end of the arm 413 and serves to support the pressing member 42. The locking block 412 is provided with a positioning structure that locks the rotational position of the locking block relative to the rotating rod. The arm 413 is fastened to the locking block 412 via bolts, allowing for multiple angle adjustments.

[0023] In addition, if Figure 2 As shown, a slide table 6 is fixed above the rotating frame 32, and a slide rail is provided on the surface of the slide table 6. A slider is provided at the bottom of the pressing mechanism to cooperate with the slide rail to achieve the sliding of the pressing mechanism.

[0024] In summary, the present application can assist the material to be welded to achieve vertical lifting and rotation at various angles. It is easy to operate and can meet the needs of multi-faceted and multi-posture welding.
