Description

Technical Field

[0001] The utility model relates to the technical field of flange welding, in particular to a flange welding butt-jointing robot. Background Art

[0002] Flange is an important component for connecting pipes, valves, pipe fittings and other equipment. It is usually used in pipeline systems. Flange connection usually adopts bolt connection. Bolts, washers and nuts are installed at both ends of the flange to achieve connection, ensuring tight connection and preventing leakage. The connection between flange and pipeline is usually welded. Welding is performed at the ends of the flange connection to ensure safe and reliable operation of the pipeline system.

[0003] However, after the existing flange welding butt robot welds the pipe and the flange, the pipe and the flange will be affected by residual stress. Generally, water cooling treatment can be performed to eliminate the influence of residual stress. However, water cooling treatment in a single direction will cause local cooling of the welding position, which will further damage the welding structure. The two ends of the flange and the pipe are respectively fixed by the flange welding butt robot, so it is inconvenient to perform circumferential uniform water cooling on the welding position. Moving the welded pipe and flange to the water cooling area is not only inconvenient, but also easy to damage the pipe and the flange. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a flange welding butt joint robot, which can solve the problem that the existing flange welding butt joint robots are inconvenient to perform circumferential uniform water cooling treatment on the flange to eliminate residual stress. The flange can be water cooled without moving the flange to eliminate the influence of residual stress, and at the same time will not hinder the stable progress of subsequent welding work.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flange welding butt joint robot, comprising a support seat, a motor is installed at the bottom of the support seat, one end of the motor is connected to a rotating shaft, a transposition assembly is arranged at the upper end of the rotating shaft, the transposition assembly comprises a dial, a ratchet and a base, the dial is fixedly connected to the rotating shaft, an active pawl and a non-return pawl are connected to the upper surface of the dial, the active pawl and the non-return pawl are respectively connected to the ratchet, a connecting shaft is arranged on the outer surface of the ratchet, and the other end of the connecting shaft is connected to the base;

[0008] A flange fixing machine and a water cooling assembly are arranged above the support seat. The water cooling assembly includes a water tank. A fixing block is installed on the upper surface of the water tank. A disc is connected to one side of the fixing block. A water pipe is connected to the inside of the disc. A nozzle is arranged on the outer surface of the water pipe.

[0009] Through the above technical solution, the positions of the flange fixing machine and the water cooling component can be converted by using the transposition component, so that after the flange and the pipeline are welded, water cooling treatment is performed through the water cooling component.

[0010] Furthermore, a welding arm is provided on the upper surface of the support seat, and the welding arm is symmetrically distributed about the longitudinal center line of the support seat. A pipeline fixing machine is provided on the upper surface of the support seat.

[0011] Through the above technical solution, the pipeline fixing machine is used to fix the pipeline, and the welding arm is used to weld the pipeline and the flange.

[0012] Furthermore, a fixed shaft is fixedly connected to the upper surface of the dial, and a positioning assembly is arranged at the upper end of the fixed shaft.

[0013] Through the above technical solution, the dial can drive the adjustment component to operate through the fixed shaft, which is beneficial to the integrated movement of the device.

[0014] Furthermore, the positioning assembly includes a gear, a rack and a load-bearing seat. The upper end of the fixed shaft is fixedly connected to the gear, the rack is fixedly connected to the load-bearing seat, and the rack and the load-bearing seat are respectively distributed in a centrally symmetrical manner about the center of the gear.

[0015] Through the above technical solution, the positioning assembly is used to drive the flange fixing machine and the water cooling assembly to adjust their positions, thereby preventing the flange fixing machine and the water cooling assembly from colliding with the pipeline and the flange during the position exchange process.

[0016] Furthermore, the connection method between the base and the support seat is a rotational connection, and the length of the base is smaller than the distance between the pipe fixing machine and the flange fixing machine.

[0017] Through the above technical solution, the base can exchange the positions of the flange fixture and the water cooling assembly by rotating, and because the length of the base is smaller than the distance between the pipe fixture and the flange fixture, sufficient space is left for the rotation of the base.

[0018] Furthermore, a slide groove is provided on the upper surface of the base, a sliding block is provided inside the slide groove, and the sliding block is fixedly connected to the load-bearing seat.

[0019] Through the above technical solution, the slider and the slide groove guide the movement of the load-bearing seat, which is conducive to ensuring that the load-bearing seat drives the flange fixing machine and the water-cooling component to move linearly.

[0020] Furthermore, the flange fixing machine and the water tank are all connected to the base in a fixed manner, and the flange fixing machine and the disc are symmetrical about the longitudinal center line of the base.

[0021] With the above technical solution, since the flange fixing machine and the disc are symmetrical about the longitudinal center line of the base, after the base is rotated, the centers of the flange fixing machine and the disc are accurately located at the center of each other.

[0022] Furthermore, the nozzles are distributed at equal distances on one side of the water pipe, a plurality of water pipes are provided, and the water pipes are distributed at equal angles with respect to the center of the disc.

[0023] Through the above technical solution, the nozzle can spray water on the welding point between the pipe and the flange, so as to achieve the purpose of water cooling treatment to eliminate the influence of residual stress.

[0024] Compared with the prior art, the utility model provides a flange welding and docking robot, which has the following beneficial effects:

[0025] In the utility model, the positions of the flange fixing machine and the water cooling component can be converted by using a position conversion component, so that after the flange and the pipeline are welded, the pipeline and the flange welding point can be uniformly water-cooled circumferentially by the water cooling component without moving the position of the pipeline and the flange, so as to eliminate the influence of residual stress. In this process, the position adjustment component can drive the flange fixing machine and the water cooling component to adjust the position, so as to avoid the flange fixing machine and the water cooling component from colliding with the pipeline and the flange during the position exchange process.

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.

[0035] See also Figure 1-Figure 7 The utility model provides a technical solution: a flange welding butt robot, including a support base 1, a motor 4 is installed at the bottom of the support base 1, one end of the motor 4 is connected to a rotating shaft 5, a transposition component is arranged on the upper end of the rotating shaft 5, and the transposition component includes a dial 6, a ratchet 9 and a base 12, the dial 6 is fixedly connected to the rotating shaft 5, an active pawl 7 and a non-return pawl 8 are connected to the upper surface of the dial 6, the active pawl 7 and the non-return pawl 8 are respectively connected to the ratchet 9, a connecting shaft 10 is arranged on the outer surface of the ratchet 9, and the other end of the connecting shaft 10 is connected to the base 12, a welding arm 2 is arranged on the upper surface of the support base 1, the welding arm 2 is symmetrically distributed about the longitudinal center line of the support base 1, and a pipe fixing machine 3 is arranged on the upper surface of the support base 1;

[0036] The principle of being able to transpose the flange fixing machine 18 and the water cooling component is: when welding the pipe and the flange, the pipe can be fixed by the pipe fixing machine 3, the flange can be fixed by the flange fixing machine 18, and then the pipe and the flange are welded by the welding arm 2. After welding, the motor 4 first drives the rotating shaft 5 to rotate forward, the rotating shaft 5 drives the dial 6 to rotate, the dial 6 drives the gear 13 to rotate through the fixed shaft 11, the gear 13 drives the rack 14 to move, the rack 14 drives the bearing seat 15 to move, and the two bearing seats 15 respectively drive the flange fixing machine 18 and the water tank 19 to move, so that the flange fixing machine 18 and the water tank 19 respectively move relative to the center of the base 12, and in this process During the process, the flange fixing machine 18 will release the fixation on the flange, so that the flange fixing machine 18 is separated from the flange, ensuring that there is a sufficient distance between the flange fixing machine 18 and the flange, and then the motor 4 drives the rotating shaft 5 to reverse, the rotating shaft 5 drives the dial 6 to reverse, the dial 6 drives the gear 13 to reverse through the fixed shaft 11, the gear 13 drives the rack 14 to move in the opposite direction, so that the rack 14 drives the flange fixing machine 18 and the water tank 19 to move in the opposite direction through the load-bearing seat 15, and at the same time, the dial 6 drives the ratchet 9 to rotate through the active pawl 7 and the check pawl 8, and the ratchet 9 drives the base 12 to rotate through the connecting shaft 10. After the base 12 rotates 180°, the position of the flange fixing machine 18 and the water cooling component is swapped.

[0037] See also Figure 1-Figure 3 A flange fixing machine 18 and a water cooling assembly are arranged above the support seat 1. The water cooling assembly includes a water tank 19. A fixing block 20 is installed on the upper surface of the water tank 19. A disc 21 is connected to one side of the fixing block 20. A water pipe 22 is connected to the inside of the disc 21. A nozzle 23 is arranged on the outer surface of the water pipe 22. The nozzles 23 are distributed at equal distances on one side of the water pipe 22. There are multiple water pipes 22, and the water pipes 22 are distributed at equal angles about the center of the disc 21.

[0038] The principle of water cooling the flange is as follows: a water pump is installed inside the fixed block 20, and the water pump sprays the water in the water tank 19 out through a nozzle 23 connected to a water pipe 22, and the nozzle 23 sprays water on the welding point between the pipe and the flange, thereby achieving the purpose of water cooling treatment to eliminate the influence of residual stress.

[0039] See also Figure 1-Figure 6 The upper surface of the dial 6 is fixedly connected with a fixed shaft 11, and a positioning assembly is provided at the upper end of the fixed shaft 11. The positioning assembly includes a gear 13, a rack 14 and a load-bearing seat 15. The upper end of the fixed shaft 11 is fixedly connected with the gear 13, the rack 14 is fixedly connected with the load-bearing seat 15, and the rack 14 and the load-bearing seat 15 are respectively distributed in a centrally symmetrical manner about the center of the gear 13.

[0040] The function of the positioning component is: the positioning component is used to drive the flange fixing machine 18 and the water cooling component to adjust the position, so as to avoid the flange fixing machine 18 and the water cooling component colliding with the pipeline and the flange during the position exchange process.

[0041] See also Figure 1-Figure 4 The connection between the base 12 and the support base 1 is a rotating connection. The length of the base 12 is less than the distance between the pipe fixing machine 3 and the flange fixing machine 18. The connection between the flange fixing machine 18 and the water tank 19 and the base 12 is a fixed connection. The flange fixing machine 18 and the disc 21 are symmetrical about the longitudinal center line of the base 12.

[0042] It is worth mentioning that the base 12 can exchange the positions of the flange fixture 18 and the water cooling assembly by rotating, and since the length of the base 12 is smaller than the distance between the pipe fixture 3 and the flange fixture 18, sufficient space is left for the rotation of the base 12.

[0043] See also Figure 1-Figure 4 A slide groove 17 is provided on the upper surface of the base 12 , a slider 16 is provided inside the slide groove 17 , and the slider 16 is fixedly connected to the load-bearing seat 15 .

[0044] It should be noted that: since the slider 16 and the slide groove 17 are slidably connected, the slider 16 and the slide groove 17 can guide the movement of the load-bearing seat 15, which is beneficial to ensure that the load-bearing seat 15 drives the flange fixing machine 18 and the water-cooling component to move linearly.
