[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figures 1-4 As shown, this utility model provides an automatic welding device for a support frame, including a base plate 1, a rotating plate 2 rotatably connected to the top of the base plate 1, T-shaped frames 3 placed at both ends of the rotating plate 2, an intermittent component 4 between the top of the base plate 1 and the bottom of the rotating plate 2, the intermittent component 4 being used to drive the rotating plate 2 to rotate intermittently, an L-shaped plate 5 fixedly connected to the top of the base plate 1 near the rotating plate 2, a sliding plate 6 slidably engaged with the side of the L-shaped plate 5 near the rotating plate 2, an mounting plate 7 fixedly connected to one side of the sliding plate 6, a welding machine 8 fixedly mounted at the bottom of the mounting plate 7, the welding pipe of the welding machine 8 corresponding to the weld seam of the T-shaped frame 3, and a welding drive component 9 provided on the top of the base plate 1 near the intermittent component 4, the welding drive component 9 being used to drive the welding machine 8 to move vertically.

[0018] The intermittent component 4 includes a gear 41, which is fixedly connected to the outside of the rotating shaft of the rotating plate 2. A connecting rod 42 is fixedly connected to the outside of the rotating shaft of the rotating plate 2 and above the gear 41. Both ends of the connecting rod 42 are provided with arc-shaped grooves 43. A half gear 44 is rotatably connected to the top of the base plate 1 near the connecting rod 42. The teeth of the half gear 44 mesh with the gear 41. An arc-shaped block 45 is fixedly connected to the outside of the rotating shaft of the half gear 44 and above the half gear 44. The side of the arc-shaped block 45 fits against the inner wall of the arc-shaped groove 43. A servo motor 46 is fixedly installed at the top of the base plate 1. The drive end of the servo motor 46 is fixedly connected to the rotating shaft of the turntable 91.

[0019] By adopting the above technical solution, the servo motor 46 drives the half gear 44 and the arc block 45 to rotate. When the half gear 44 rotates to the point where the toothed part meshes with the gear 41, it drives the gear 41, the connecting rod 42 and the rotating plate 2 to rotate 180 degrees. When the arc block 45 rotates into the inside of the arc groove 43, the gear 41 and the half gear 44 no longer mesh. The rotation of the half gear 44 will not drive the rotating plate 2 to rotate, thereby achieving a short pause of the rotating plate 2.

[0020] The welding drive assembly 9 includes a turntable 91, which is fixedly connected to the top of the rotating shaft of the half gear 44. A rotating rod 92 is rotatably connected to one side of the top of the turntable 91. A guide plate 93 is fixedly connected to the top of the base plate 1 near the turntable 91. A telescopic rod 94 is movably passed through the top of the guide plate 93. The end of the rotating rod 92 away from the turntable 91 is rotatably connected to one end of the telescopic rod 94. The welding drive assembly 9 also includes two symmetrically distributed fixed plates 95, which are fixedly connected to the bottom of the slide plate 6. An inclined groove 96 is provided on the bottom of each fixed plate 95. A transverse rod 97 is fixedly connected to the end of the telescopic rod 94 away from the rotating rod 92. The two ends of the transverse rod 97 are movably engaged in the corresponding inclined groove 96.

[0021] By adopting the above technical solution, when the half gear 44 rotates, it drives the turntable 91 to rotate. Utilizing the connecting action of the rotating rod 92, it simultaneously drives the telescopic rod 94 to move laterally back and forth along the top of the guide plate 93, and drives the transverse rod 97 to move laterally back and forth. Utilizing the cooperation between the inclined groove 96 and the transverse rod 97, it simultaneously drives the fixed plate 95 and the sliding plate 6 to move vertically, thereby driving the welding machine 8 to move vertically back and forth, realizing the vertical welding operation of the T-shaped frame 3.

[0022] Limiting fixtures 10 are provided on both sides of the top of the rotating plate 2, and the T-shaped frame 3 is snapped into the limiting fixtures 10.

[0023] By adopting the above technical solution, the component plates of the T-shaped frame 3 are placed inside the limiting fixture 10, and the position of the T-shaped frame 3 is limited by the limiting fixture 10.

[0024] Working principle: When automatically welding the T-shaped support frame, the component plates of the T-shaped frame 3 are placed inside the limiting fixture 10. The limiting fixture 10 limits the position of the T-shaped frame 3. Then, the servo motor 46 drives the half gear 44 and the arc block 45 to rotate. When the half gear 44 rotates to the point where the toothed part meshes with the gear 41, it drives the gear 41, the connecting rod 42 and the rotating plate 2 to rotate 180 degrees. When the arc block 45 rotates into the arc groove 43, the gear 41 and the half gear 44 no longer mesh. The rotation of the half gear 44 will not drive the rotating plate 2 to rotate, thus achieving a short pause of the rotating plate 2.

[0025] When the half gear 44 rotates, it drives the turntable 91 to rotate. Utilizing the connecting action of the rotating rod 92, when the rotating plate 2 rotates, it drives the telescopic rod 94 and the transverse rod 97 to move away from the fixed plate 95. Utilizing the cooperation between the inclined groove 96 and the transverse rod 97, it simultaneously drives the fixed plate 95 to move downwards. When the rotating plate 2 is in a resting phase, the turntable 91 continues to rotate with the half gear 44, while simultaneously driving the telescopic rod 94 to move to one side of the fixed plate 95, pushing the fixed plate 95 upwards. At the same time, the welding machine 8 performs welding operations on the T-shaped plate from bottom to top.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
