They have strong corrosion resistance, are not easy to oxidize, and are not easy to chemically react with some liquid substances. They are easy to bend and shape.

[0003] During the existing copper pipe welding operation, the welding process is generally carried out by manual operation in conjunction with equipment such as welding machines. During the welding process, unstable welding is prone to occur, which in turn affects the welding quality of the copper pipe. Utility Model Content

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0021] Reference Figure 1-2, a copper pipe welding and fixing device, including a base 1 and a clamping assembly and a support assembly installed on the base 1, the support assembly includes a telescopic frame 6, a fixed cylinder 7, a stud 8, a nut 9, a roller 10, a support frame 11, a movable seat 12, a second screw 13 and a second nut 14, the fixed cylinder 7 is two, respectively fixed at both ends of the telescopic frame 6, the support frame 11 is inserted into the fixed cylinder 7 through the stud 8, the nut 9 rotates on the stud 8 to limit the stud 8 from moving downward in the fixed cylinder 7, the roller 10 is fixed to the bottom of the fixed cylinder 7, the second screw 13 is fixed on the support frame 11, the movable seat 12 is two opposite, and is sleeved on the second screw 13, and the second nut 14 is rotatably installed on the second screw 13 to limit the corresponding one of the movable seats 12 from moving to one side;

[0022] The support components on both sides can be pushed and pulled by the telescopic frame 6, and the support components are moved by the roller 10 at the bottom thereof. Then, the height of the support frame 11 can be adjusted up and down, and the nut 19 on the stud 8 can be turned to limit the stud 8 from moving downward in the fixed cylinder 7. Then, the two copper tubes can be placed on a group of movable seats 12 for support, and one end of the two copper tubes is between the limit part 14 and the limit part 2 5, and then the screw 13 is turned to push the limit part 14 to clamp the ends of the two copper tubes. Then, the height of the support frame 11 can be fine-tuned according to actual conditions, and the nut 2 14 can also be loosened to adjust the position of the movable seat 12, and then the movable seat 12 is locked on the screw 2 13 by the nut 2 14. At this time, the middle position of the copper tube is in the middle position of the movable seat 12, thereby supporting the copper tube more stably. After the adjustment is completed, the ends of the copper tube can be welded. During this period, the limit part 14 can be loosened to adjust the welding position of the copper tube.

[0023] The clamping assembly includes a supporting part 2, a screw rod 3, a limiting part 4 and a limiting part 2 5. The screw rod 3 is rotatably installed on the supporting part 2, the limiting part 4 is rotatably installed on the end of the screw rod 3, and the limiting part 2 5 is fixed on the base 1 and is arranged corresponding to the limiting part 4; a groove is also provided in the middle of the limiting part 1 4 and the limiting part 2 5, and the two copper tubes can be clamped by the limiting part 1 4 and the limiting part 2 5, and the ends of the two copper tubes are placed in the groove in the middle, so that when the ends of the copper tubes are restricted, the ends of the copper tubes can expose more areas, which is convenient for the staff to weld them; it should be noted that the ends of the two copper tubes need to be placed between the limiting part 1 4 and the limiting part 2 5 so that they are completely corresponding to each other, so as to facilitate the subsequent welding of the copper tubes.

[0024] The telescopic frame 6 is a multi-stage telescopic structure, which can be stretched to both ends and retracted to the middle. When welding the copper tube, the telescopic frame 6 can be stretched to both sides, thereby supporting the copper tube through the movable seat 12. When the device is not in use, the two sides of the telescopic frame 6 can be retracted for easy storage of the device.

[0025] The limiting portion 1 4 and the limiting portion 2 5 are both L-shaped plate structures; the limiting portion 1 4 and the limiting portion 2 5 can clamp the copper tube and clamp the copper tube stably.

[0026] The movable seat 12 is a truncated cone-shaped structure with a threaded hole in the middle. The distance between the two movable seats 12 on the screw rod 13 can be adjusted according to the size of the copper tube so that the movable seat 12 supports the bottom of the copper tube. The movement of the movable seat 12 is restricted by the nut 14, so that the movable seat 12 can stably support the copper tube.

[0027] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
