[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, in the embodiment of the present invention, an automatic welding device for a fire truck tank body includes a base plate 1. In the middle of the top of the base plate 1, there is a distance adjustment mechanism 2. Above the distance adjustment mechanism 2, there is a clamping mechanism 4. The clamping mechanism 4 includes a positioning disk 41. On the surface of one end of the positioning disk 41, a plurality of guiding grooves 410 are equidistantly arranged. Inside the guiding grooves 410, a clamping plate 43 is slidably connected. At the outer edge of the surface of one end of the clamping plate 43, a limiting post block 49 is fixedly connected. At one end of the clamping plate 43, there is an adjusting turntable 44. On the surface of one end of the adjusting turntable 44, push arc grooves 48 matching the number of the clamping plates 43 are equidistantly arranged. The limiting post block 49 can be slidably connected with the push arc grooves 48. In the middle of the bottom end of the adjusting turntable 44, a second gear 47 is meshed and connected. In the middle below one end of the positioning disk 41, there is a fixed arc plate 46. Through the middle of the fixed arc plate 46, there is a second electric telescopic rod 45. At the top of the second electric telescopic rod 45, a supporting hoop arc plate 411 is fixed. The fixed arc plate 46 is fixedly connected with the top of one end of the supporting plate 23.

[0026] In this embodiment: When clamping, the second electric telescopic rod 45 drives the supporting hoop arc plate 411 fixedly connected to the top to move up an appropriate height, so that the middle of one end of the tank body can be aligned with the middle of the positioning disk 41. Place the tank body above the supporting hoop arc plate 411, so that the bottom of the tank body is stuck on the upper surface of the supporting hoop arc plate 411, and the left and right ends of the tank body are respectively stuck in the middle of the corresponding positioning disk 41. Then, the rotating second gear 47 drives the adjusting turntable 44 meshed and connected to the top to rotate. The rotating adjusting turntable 44 will drive the push arc grooves 48 arranged on the surface to rotate synchronously, so that the position of the push arc grooves 48 close to the middle of the adjusting turntable 44 slowly slides onto the limiting post block 49 fixedly connected to one end of the clamping plate 43. Thus, the clamping plate 43 fixed to one end of the limiting post block 49 is pushed through the limiting post block 49 to slide on the surface of the tank body under the guidance of the guiding grooves 410, so that the suction cup fixed to the lower surface of the limiting post block 49 is clamped to the tank body, thereby completing the clamping and fixing of the tank body.

[0027] Please refer specifically to Figure 1 , Figure 2 and Figure 6 , the distance adjustment mechanism 2 includes a sliding groove 21. The sliding groove 21 is arranged in the middle of the upper surface of the base plate 1. Inside the sliding groove 21, a sliding block 25 is slidably connected. Through the middle of the sliding block 25, there is a screw rod 22. The left and right ends of the screw rod 22 are respectively rotatably connected to the left and right ends inside the sliding groove 21. At the position where the left end of the screw rod 22 penetrates through the middle of one end of the base plate 1, a first gear 24 is fixed. In the middle of the top end of the sliding block 25, a supporting plate 23 is fixedly connected.

[0028] In this embodiment: When adjusting the distance, the rotating first gear 24 drives the screw rod 22 fixedly connected to the middle of one end to rotate. At this time, the thread on the outside of the screw rod 22 interacts with the thread on the inside of the slider 25, thereby pushing the slider 25 to translate a specified distance along the chute 21 towards one end. During the process of the slider 25 sliding and translating towards one end, it drives the support plate 23 fixedly connected to the middle of the top of the slider 25 to synchronously slide and translate a specified distance, so that the distance between the support plate 23 fixedly connected above the slider 25 and the support plate 23 fixedly connected to the middle of one end of the top of the base plate 1 reaches the specified spacing size, facilitating the adjustment of the distance between the clamping mechanisms installed above the support plate 23 and facilitating the clamping and fixing of containers of different sizes.

The rotating fourth gear 57 drives the first gear 24 meshed at the bottom end to rotate. When it is necessary to drive the drive gear 55 to rotate, the first electric telescopic push rod 31 drives the motor 56 provided at the top of the mounting plate 34 fixedly connected to one end to move towards one end through the mounting plate 34 fixedly connected to one end. At the same time, the motor 56 pushes the fourth gear 57 fixedly connected to the output end to move below the third gear 52.

When the fourth gear 57 is stuck to the bottom of the third gear 52, the pushing block 35 will be synchronously stuck to the lower surface of one end of the limiting disk 53. At this time, when the first electric telescopic push rod 31 continues to push the motor 56, the fourth gear 57 and the pushing block 35 to move towards one end through the mounting plate 34, the pushing block 35 will drive the shaft rod 51 fixedly connected to the middle through the clamped limiting disk 53 to move towards one end by an appropriate distance under the restriction of the guiding slide rod 32. When the annular slot 59 opened on the surface of the appropriate shaft rod 51 reaches the position of the block fixed inside the second gear 47, the pushing ring block 510 fixed on the surface of the appropriate shaft rod 51 is stuck to the block fixed inside the fifth gear 58, which is convenient for adjusting the position of the fourth gear 57 and is convenient for driving the screw rod 22 and the shaft rod 51 to rotate respectively.
