DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 The utility model provides a technical solution: an automatic welding machine adapted to steel pipes of different diameters, comprising a workbench 1, a mounting frame 2 arranged on one side of the upper part of the workbench 1, a side plate 5 arranged on the other side of the upper part of the workbench 1, and a welding machine 6 arranged on the side plate 5, wherein the welding machine 6 is adjustable and arranged on the side plate 5 through an electric slide rail 61, and further comprising:

[0027] An adjustment unit 4 is arranged on the mounting frame 2;

[0028] The fixing unit 3 is arranged on the adjusting unit 4, and is driven by the adjusting unit 4 to fix steel pipes of different sizes;

[0029] The clamping unit 7 is arranged on the side plate 5 and is used to fix the steel pipe.

[0030] It should be noted that, during operation, the two sections of steel pipes to be welded are placed on the fixing unit 3 and the clamping unit 7 respectively, and then the fixing unit 3 is adjusted by the adjusting unit 4 so that the fixing unit 3 fixes the steel pipe, and then the fixing unit 3 adjusts the position of the steel pipe so that the steel pipe on the fixing unit 3 moves toward the side close to the clamping unit 7, and then the welding points of the two steel pipes are fitted together, and then the welding machine 6 is turned on to weld the steel pipe, and the welding machine 6 is driven by the electric slide rail 61 to rotate along the steel pipe to weld and fix the steel pipe.

[0031] In one embodiment, the adjusting unit 4 includes a screw rod 41 that passes through the mounting frame 2 and has its bottom disposed on the upper part of the workbench 1, a center block 46 that is sleeved on the middle of the screw rod 41, and screw rod sleeves 43 that are symmetrically disposed on both sides of the center block 46 and threadedly connected to the screw rod 41. The screw rod sleeves 43 are connected to the fixing unit 3, and the screw rod 41 is located on both sides of the center block 46 with opposite rotation directions of the threads.

[0032] With this design, by rotating the screw rod 41, the screw rod sleeve 43 moves symmetrically about the center block 46, thereby driving the two fixing units 3 to move closer to or away from each other about the center block 46, so that the center of the steel pipe is always aligned with the center block 46. The screw rod 41 adjusts the installation position of the fixing unit 3, so that the fixing unit 3 can fix steel pipes of different sizes, so that the welding machine 6 can be used to weld steel pipes of different sizes, and the position of the welding machine 6 can be manually adjusted according to the size of the steel pipe.

[0033] In one embodiment, a slider 44 is disposed on one side of the fixing unit 3 close to the mounting frame 2, a guide rod 45 is disposed on the mounting frame 2, and the slider 44 is sleeved on the guide rod 45;

[0034] A rotating disk 42 is disposed on the upper portion of the screw rod 41 .

[0035] With such a design, when the screw rod 41 drives the fixing unit 3 to move up and down, the slider 44 slides on the guide rod 45, and the guide rod 45 can limit the movement state of the fixing unit 3, so that the fixing unit 3 can move up and down smoothly, avoiding the fixing unit 3 from tilting when moving up and down, thereby improving the stability of the fixing unit 3 fixing the steel pipe.

[0036] In one embodiment, the fixing unit 3 includes a mounting plate 31 connected to the slider 44, a first motor 32 arranged on the mounting plate 31, a rotating shaft 33 arranged at the power output end of the first motor 32, a gear 34 sleeved on the rotating shaft 33, and a chain 35 sleeved on the gear 34 and meshed with the gear 34, and a track clamp 36 for fixing the steel pipe is arranged on the chain 35.

[0037] With this design, the first motor 32 is started, the rotating shaft 33 is driven to drive the gear 34 to rotate, so that the chain 35 drives the track clamp 36 to move, and then the steel pipe clamped between the two sets of track clamps 36 is moved, so that the position of the steel pipe can be easily adjusted, so that the welding points of the two steel pipes are in contact.

[0038] In one embodiment, the track clamping blocks 36 are symmetrically arranged about the center block 46 , and grooves are formed on the track clamping blocks 36 .

[0039] With such a design, when the steel pipe needs to be fixed, the turntable 42 is rotated so that the screw rod 41 moves the two sets of track clamps 36 away from each other, and then the steel pipe is placed between the two sets of track clamps 36. The turntable 42 is then rotated to drive the two sets of track clamps 36 to move toward each other, so that the track clamps 36 clamp and fix the steel pipe.

[0040] In one embodiment, the clamping unit 7 includes a fixing frame 71 arranged on the side plate 5, a second motor 72 arranged on the upper part of the fixing frame 71, a screw rod 73 arranged at the power output end of the second motor 72, a connecting block 76 sleeved on the screw rod 73, and a clamping claw 75 arranged on the side of the adjusting rod 74 away from the fixing frame 71, the upper part of the adjusting rod 74 is connected to the connecting block 76, and the inner side of the clamping claw 75 is connected to the fixing frame 71 through a rotating rod.

[0041] With this design, the second motor 72 drives the screw rod 73 to rotate, so that the screw rod 73 drives the connecting block 76 to move upward on the screw rod 73, and then the adjusting rod 74 drives the two clamping jaws 75 to move closer to each other, so that the clamping jaws 75 clamp the steel pipe tightly.

[0042] In addition, if there are descriptions involving "first", "second", etc. in the embodiments, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying the importance of the relative description or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
