DETAILED DESCRIPTION

[0017] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0018] like Figure 1-3As shown, a positioning welding platform for sheet metal processing includes a base frame 1, a workbench 3, a rotating plate 4 and an adjusting mechanism. The workbench 3 is connected to the base frame 1, and the adjusting mechanism is connected to the side of the base frame 1. One end of the workbench 3 is provided with an upwardly open rectangular groove 301, and the output end of the adjusting mechanism extends into the rectangular groove 301. One end of the rotating plate 4 is hinged in the rectangular groove 301, and the other end of the rotating plate 4 is in contact with the output end of the adjusting mechanism up and down; the flatness error of the surfaces of the workbench 3 and the rotating plate 4 is low, and the plates to be welded can be seamlessly fitted when placed on the workbench 3 and the rotating plate 4, thereby ensuring seamless splicing between the plates; the output end of the adjusting mechanism is used to make the rotating plate 4 drive the plates to be lifted to a certain angle, so that the plates to be welded are abutted against each other, and the plates are clamped with a universal clamp, and then the welding operation can be carried out.

[0019] 7021 , the guide post 10 is fixedly connected to the vertical plate 702 . One end of the screw rod 8 is provided with a crank 9, which can be rotated by shaking it, which is convenient and quick. One end of the rotating plate 4 is provided with an arc surface, which abuts against the inclined plate 701, so that the sliding connection between the rotating plate 4 and the inclined plate 701 is smoother when the inclined plate 701 moves back and forth, avoiding sharp corners from wearing the inclined plate 701. One end of the rotating plate 4 is provided with a groove 401, and a clamping plate 6 is slidably connected in the groove 401. The bottom of the groove 401 and the clamping plate 6 are connected by a tension spring 5. The upper end of the clamping plate 6 is perpendicular and protrudes from the upper end surface of the rotating plate 4; the tension spring 5 can pull the clamping plate 6, and through the clamping plate 6, the plate is pulled to the surface of the rotating plate 4, so that the plate is tightly abutted against one end of the plate of the workbench 3, thereby improving the connection strength after welding.

[0020] The workbench 3 and the rotating plate 4 are both provided with screw holes 12 on their surfaces for positioning and installing universal fixtures to facilitate the fixing of the plates. The lower end of the base frame 1 is provided with a support leg 2, which is provided with a positioning hole 201. This allows the workbench 3 to be raised for easier processing and cleaning under the base frame 1. The positioning hole 201 is used to lock the expansion screw.

[0021] Description of the working method of this utility model:

[0022] Place the two plates to be welded on the workbench 3 and the rotating plate 4 respectively. After the two plates are abutted, shake the crank 9 to move the adjusting plate 7 forward, and support the rotating plate 4 through the inclined plate 701 of the adjusting plate 7; measure the lifting angle of the rotating plate 4 through the angle measuring tool. After the lifting angle meets the welding requirements, the plate placed on the workbench 3 is tightly abutted against one end of the plate on the rotating plate 4. At this time, the plate placed on the rotating plate 4 opens the clamp 6 and pulls the tension spring 5 to ensure the tightness between the two plates. Then, the universal clamp can be used to lock the screw holes 12 on the workbench 3 and the rotating plate 4, and the two plates are locked separately. Then spot welding and arc welding operations are carried out to achieve the processing requirements of sheet metal weldments with a certain angle.
