DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0019] See also Figure 1 , Figure 2 and Figure 3This patent provides a technical solution: a pipe welding bracket that is easy to clamp, including a base 1, a clamping mechanism is provided on both the left and right sides of the top of the base 1, and pipes are provided inside the two clamping mechanisms;

[0020] The clamping mechanism includes a vertical plate 2 and a bearing 5. The bottom end of the vertical plate 2 is fixedly mounted on the top of the base 1. A circular hole 3 is provided in the middle of the vertical plate 2. An annular groove 4 is provided on the inner wall of the circular hole 3. The outer wall of the outer ring of the bearing 5 is fixedly mounted on the inner wall of the annular groove 4. A swivel 6 is fixedly mounted on the inner wall of the inner ring of the bearing 5. A connecting column 7 is fixedly mounted on the left side of the bottom end of the inner wall of the swivel 6. A lower clamping plate 8 is integrally formed on the top of the connecting column 7. Two pipelines are respectively located on the two lower clamping plates 8. A cylinder 9 is fixedly mounted on the left side of the top end of the outer wall of the swivel 6. The bottom end of the piston rod of the cylinder 9 passes through the swivel 6 and is fixedly mounted on an upper clamping plate 10. The outer wall of the swivel 6 on the left side is provided with tooth grooves 11 distributed continuously in a circle.

[0021] A rotating cylinder 12 is fixedly mounted on the top left end of the base 1. An oil circuit switch for controlling the rotating cylinder 12 is provided on the top of the base 1. A disc 13 is fixedly mounted on the left end of the rotating shaft of the rotating cylinder 12. A gear 14 is fixedly mounted on the side wall of the disc 13. The top end of the gear 14 is meshed with the tooth groove 11 on the bottom side.

[0022] Specifically, a start switch for controlling the cylinder 9 is installed on the outer side wall of the swivel 6 .

[0023] Since the air cylinder 9 is installed on the swivel 6 and needs to rotate simultaneously with the swivel 6, if the driving component of the air cylinder 9 is set in a fixed position, the line is easy to curl.

[0024] Specifically, the top of the lower clamping plate 8 and the bottom of the upper clamping plate 10 are both provided with an arc groove 15, and the inner curvature of the arc groove 15 matches the curvature of the outer wall of the pipe.

[0025] The arc groove 15 matching the curvature of the outer wall of the pipeline is provided to increase the clamping area of ​​the pipeline.

[0026] Specifically, a rubber pad is embedded in the arc groove 15, and the curvature of the rubber pad matches the curvature of the outer wall of the pipe.

[0027] The rubber pad can increase the friction fixing effect on the pipe.

[0028] Specifically, the vertical plate 2 includes a first plate body 16 and a second plate body 17. The inner walls of the first plate body 16 and the second plate body 17 are both provided with semi-annular grooves, and the two semi-annular grooves are combined into an annular groove 4. The right side surface of the first plate body 16 and the left side surface of the second plate body 17 are connected.

[0029] like Figure 3As shown, by dividing the vertical plate 2 into the first plate body 16 and the second plate body 17 , the annular groove 4 can be conveniently divided into two parts, which is convenient for opening the annular groove 4 in the early stage and also convenient for installing the bearing 5 in the annular groove 4 .

[0030] Specifically, mounting holes 18 are provided at both upper and lower ends of the right side surface of the second plate body 17 , and screw rods 19 are integrally formed at both upper and lower ends of the right side surface of the first plate body 16 . The right end of the screw rod 19 passes through the mounting hole 18 and is screwed with a nut 20 .

[0031] Working principle: Figure 2 As shown, the end welding positions of the two pipes are aligned together, and the upper clamping plate 10 is controlled by the cylinder 9 to move downward, and the pipe is clamped with the lower clamping plate 8, so that the pipe and the swivel 6 are integrated into one. The welder can weld the end of the pipe on the front side of the base 1, and then the gear 14 can be controlled to rotate by the rotating cylinder 12 to drive the swivel 6 to rotate, which can drive the pipe to rotate, and then change the welding position. There is no need for the welder to frequently change positions, which is convenient to operate and reduces labor intensity.
