[0021] refer to Figure 1 As shown, an embodiment of the present utility model is:

[0022] The rotary welding table includes a base 1, on which a drive motor 2 is provided. The output shaft of the drive motor 2 is connected to a rotary welding plate 4 through a connecting flange 3. A plurality of support arms 5 are provided on the base 1 on the outside of the drive motor 2. A roller 6 is installed at the upper end of the support arm 5, and the roller 6 is in contact with the lower end of the rotary welding plate 4.

[0023] Furthermore, a welding gun holder 7 is mounted on the outer side wall of the base 1 through an extension plate. A lifting slider 8 is provided on the welding gun holder 7. A welding gun mounting plate 9 is provided on the side of the lifting slider 8 facing the rotary welding plate 4.

[0024] The rotary welding plate 4 is driven to rotate by the driving motor 2 to realize automatic rotation of the welding rotary platform. The welding gun can be fixed on one side of the rotary welding plate 4 to realize automatic welding, which can effectively reduce the work intensity of workers and improve production efficiency.

[0025] The support arm 5 cooperates with the roller 6 to further support the rotary welding plate 4, thereby improving the stability of the rotary support plate.

[0026] In this embodiment, a lifting screw 10 is installed on the upper end of the welding gun frame 7 through a connecting plate, and a screw nut 11 adapted to the lifting screw 10 is provided on the lifting slider 8.

[0027] The lifting screw is connected to the external drive mechanism, and the lifting slider 8 is driven by the screw, which has a simple structure and is easy to implement. When the processing machine is fixed for a long time, the locking screw connected to the side wall of the lifting slider 8 can be used to lock and fix it to improve stability.

[0028] In this embodiment, in order to facilitate the installation and centering of the plates before welding, an annular positioning piece is provided in the middle of the rotary welding plate 4, and a plurality of L-shaped outer ring limit blocks 12 are evenly provided on the rotary welding plate 4 on the outside of the annular positioning piece. A support pad 13 is provided on the rotary welding plate 4 between the annular positioning piece and the L-shaped outer ring limit block bracket 12.

[0029] The annular positioning member includes a plurality of surrounding inclined positioning blocks 14 , and the thickness of the support pad 13 is consistent with the thickness of the side wall of the L-shaped outer ring limiting block 12 .

[0030] The annular positioning piece can achieve the centering of the inner ring plate more quickly, and the L-shaped outer ring limit block can achieve the positioning of the outer ring, thereby improving welding efficiency.

[0031] Furthermore, in order to prevent the outer ring plate from rotating relative to each other before welding, a mounting notch 15 is provided on the rotary welding plate 4 on the outside of the L-shaped outer ring limit block 12, and a mounting shaft is provided on the mounting notch 12, and an L-shaped outer ring clamping plate 16 is installed on the mounting shaft, and a strip hole 17 adapted to the mounting shaft is provided on one side plate of the L-shaped outer ring clamping plate 16, and a protective pad 18 is bonded to the other side plate of the L-shaped outer ring clamping plate 16.

[0032] Through the design of the strip hole 17, after the panel is placed, the L-shaped outer ring pressure plate can be flipped over so that the other side plate of the L-shaped outer ring pressure plate 16 is pressed against the top of the panel, ensuring the stability of the position of the panel and improving the installation efficiency. The provided protective pad 18 can increase the friction with the panel while avoiding damage to the panel.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
