[0019] The technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0020] Please refer to Figs. 1-3The utility model provides a technical scheme: a kind of metal pipe automatic welding mechanism, including support seat 1, clamping device 2 and limit tube sleeve 3, limit tube sleeve 3 is fixedly arranged in the center of support seat 1, clamping device 2 is equipped in support seat 1 both sides, clamping device 2 includes clamping arm 4 and the cylinder 5 being connected with clamping arm 4, clamping arm 4 is close to the side of limit tube sleeve 3 and is provided with clamping jaw 6, limit hole 7 is opened on clamping arm 4, and limit block 8 for the limit of clamping arm 4 is arranged in limit hole 7, support seat 1 is also provided with the support ring 9 corresponding with limit tube sleeve 3, three support top rod 10 are also fixedly arranged in support ring 9, support top rod 10 abuts limit tube sleeve 3, limit support ring 9 bottom is fixedly connected with fixed seat 11, and fixed seat 11 is fixed on support seat 1 by bolt.

[0021] Specifically, the inner width of the clamping jaw 6 corresponds to the width of the limit tube sleeve 3, and the clamping jaw 6 is inclined downward by about 30° along the clamping arm 4 in the direction of the limit sleeve. Through the above arrangement, the metal pipe can be stably fixed during welding, thereby improving the welding quality and efficiency, and the clamping jaw 6 can more accurately clamp the limit tube sleeve 3.

[0022] Specifically, the bottom of the support seat 1 is provided with a U-shaped groove 12 on both sides, and the width of the U-shaped groove 12 is greater than the width of the cylinder 5. By arranging the U-shaped groove 12, the installation of the cylinder 5 in the clamping device 2 is more convenient, and adjusting the position of the cylinder 5 does not easily affect the support seat 1. In addition, the design of the U-shaped groove 12 can also increase the strength and stability of the support seat 1.

[0023] Specifically, the three support top rods 10 in the support ring 9 are evenly distributed, and the included angle between the three support top rods 10 is about 120°. Through the above arrangement, the limit tube sleeve 3 can be uniformly supported during welding to prevent deformation under high temperature during welding, so as to ensure that the limit tube sleeve 3 can be stably fixed on the support top rod 10 during welding, thereby ensuring the welding precision.

[0024] One specific application example of the embodiment is as follows:

[0025] When using the device, first place the metal pipe to be welded in the limit tube sleeve 3, then start the clamping device 2, the cylinder 5 pushes the clamping arm 4 to move, so that the clamping jaw 6 clamps the metal pipe. Since the clamping jaw 6 is inclined downward by about 30° along the clamping arm 4 in the direction of the limit sleeve, it can more effectively clamp the metal pipe to prevent displacement during welding.

[0026] Then, the operator can adjust the position of the supporting top rod 10, ensure that the limiting tube sleeve 3 is in close contact with the supporting top rod 10, so as to provide stable support during the welding process. Since the supporting top rods 10 are uniformly distributed, the included angle between the three supporting top rods 10 is about 120°, the limiting tube sleeve 3 can be uniformly supported at high temperature during welding, and deformation is avoided.

[0027] Finally, when everything is ready, the welding equipment is started, and the metal pipe can be kept stable under the joint action of the clamping device 2 and the supporting top rod 10, so as to realize automatic welding of high quality. After welding, the air cylinder 5 is retracted, the clamping jaw 6 releases the metal pipe, and the operator can easily take out the welded metal pipe for the next processing or inspection.
