[0002] Metal pipe fittings are tubular components made of metal materials and are widely used in pipeline transportation, machinery manufacturing and other fields. With their high strength, corrosion resistance, good sealing and thermal conductivity, metal pipe fittings have become a key component in various fluid transportation systems and mechanical assemblies. Their quality and specifications directly affect the stability and safety of the entire system.

[0003] Currently, in practical applications, due to the need for extended pipe fittings, new pipe fittings are formed by welding the base pipe fitting and the extended pipe fitting together, and then this pipe fitting is used in subsequent production. Existing pipe fitting welding is mostly done manually, which connects two pipe fittings into a whole.

[0004] However, in manual welding of pipe fittings, different operators have different welding techniques, resulting in different welding effects and thus different welding quality. At the same time, manual welding is time-consuming, labor-intensive, and inefficient, affecting the production rate of pipe fittings. Therefore, an adjustable circumferential weld device for pipe fittings is proposed to improve the existing problems. Utility Model Content

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0033] Please see Figures 1-5 The present invention provides the following technical solution:

[0034] Example 1, see Figure 1 An adjustable circumferential welding device for pipe fittings includes a welding assembly 1. A first clamping assembly 2, two sets of auxiliary assemblies 3, and a second clamping assembly 4 are sequentially arranged on one side of the welding assembly 1. A pipe body assembly 5 is arranged above the auxiliary assemblies 3.

[0035] See Figure 3 The pipe assembly 5 includes a pipe fitting 51, and a connector 52 is provided at one end of the pipe fitting 51.

[0036] The first clamping component 2 is used to clamp the pipe fitting 51, the two sets of auxiliary components 3 are used to assist the normal progress of welding work, and the second clamping component 4 is used to clamp the connector 52. By adjusting the first clamping component 2 and the second clamping component 4 towards each other, the pipe fitting 51 and the connector 52 can be connected, which facilitates the normal progress of subsequent welding work.

[0037] The connection between the pipe fitting 51 and the connector 52 is welded using welding assembly 1. The specific structure of welding assembly 1 is as follows:

[0038] See Figure 2 and Figure 3 The welding assembly 1 includes a third electric slide rail 13, a mounting bracket 14 is provided on one side of the third electric slide rail 13, and a welding head 15 is provided at the bottom of the mounting bracket 14.

[0039] See Figure 2 and Figure 3 The welding assembly 1 also includes a support frame 16, a first electric slide rail 11 is provided above the support frame 16, a second electric slide rail 12 is provided above the first electric slide rail 11, and a third electric slide rail 13 is provided on one side of the second electric slide rail 12.

[0040] The working principle of the first electric slide rail 11, the second electric slide rail 12, and the third electric slide rail 13 is to use a motor to provide power, and convert the rotational motion of the motor into linear motion through a reducer, a synchronous belt, and a ball screw, thereby driving the slider on the slide rail to move along the slide rail.

[0041] Activating the first electric slide rail 11 enables the second electric slide rail 12, the third electric slide rail 13, the mounting bracket 14, and the welding head 15 to move horizontally in the left and right directions. Activating the second electric slide rail 12 enables the third electric slide rail 13, the mounting bracket 14, and the welding head 15 to move horizontally in the front and back directions. Under the action of the third electric slide rail 13, the mounting bracket 14 and the welding head 15 can move vertically. Therefore, the first electric slide rail 11, the second electric slide rail 12, and the third electric slide rail 13 can enable the welding head 15 to move in all directions, facilitating the adjustment of the position of the welding head 15 during subsequent welding operations.

[0042] The pipe fitting 51 is the base part, and the connector 52 is the extension part. A new workpiece can be formed by welding the pipe fitting 51 and the connector 52 together. During the welding process, the pipe fitting 51 and the connector 52 need to be clamped separately to reduce the welding of the pipe fitting 51 and the connector 52 during the welding process. The first clamping component 2 is set to facilitate the clamping of the pipe fitting 51.

[0043] The specific structure of the first clamping component 2 is as follows:

[0044] See Figure 4 The first clamping assembly 2 includes an electric clamping plate 26, and the tube 51 is disposed in the middle position of the electric clamping plate 26.

[0045] See Figure 2 The first clamping assembly 2 also includes a worktable 21, on the top of which is a transfer cylinder 22, and the output end of the transfer cylinder 22 is connected to a sliding frame 24.

[0046] See Figure 4 The top of the workbench 21 is provided with a rail 25, which slides relative to the sliding frame 24. A rotary motor 23 is provided on one side of the sliding frame 24.

[0047] See Figure 2 The output end of the rotary motor 23 passes through the sliding frame 24 and is connected to the electric chuck 26. The electric chuck 26 and the sliding frame 24 are rotatably connected.

[0048] Among them, the electric chuck 26 is an automated clamping device driven by electricity. The electric chuck 26 includes a clamping motor, a gripper, and a housing. The clamping motor can drive the movement of the gripper. The outer side wall of the housing is rotatably connected to one side of the sliding frame 24. The output end of the rotary motor 23 passes through one side of the sliding frame 24 and is connected to one end of the housing.

[0049] The pipe 51 can be clamped by the electric clamp 26. Starting the rotary motor 23 can drive the electric clamp 26 to rotate, and then the pipe 51 will follow the electric clamp 26 to rotate.

[0050] In addition, the output end of the transfer cylinder 22 is connected to one side of the sliding frame 24, and the bottom of the sliding frame 24 slides relative to the track 25. Therefore, when the transfer cylinder 22 is activated, the transfer cylinder 22 can drive the sliding frame 24 to slide along the track 25, thereby adjusting the position of the sliding frame 24. As a result, the track 25 can follow the sliding frame 24 to adjust its position, which facilitates the docking of the pipe fitting 51 and the connector 52, and facilitates the normal progress of subsequent welding work.

[0051] Since both the pipe fitting 51 and the connector 52 are cylindrical, and the welding point between the pipe fitting 51 and the connector 52 is an annular welding point, the pipe fitting 51 and the connector 52 are first spot welded, and then the rotary motor 23 is started to drive the track 25 and the pipe fitting 51 to rotate as a whole to achieve the annular welding of the welding point.

[0052] Based on the above structure, a second clamping assembly 4 is provided to clamp and transfer the connector 52, facilitating the normal progress of subsequent welding work. The specific structure of the second clamping assembly 4 is as follows:

[0053] See Figure 5 The second clamping assembly 4 includes a clamping mechanism 43, and a connector 52 is disposed in the middle position of the clamping mechanism 43.

[0054] See Figure 2 The second clamping assembly 4 also includes a placement platform 41, a fourth electric slide rail 42 is provided on the top of the placement platform 41, a sliding plate 44 is provided above the fourth electric slide rail 42, and a clamping mechanism 43 is provided on the top of the sliding plate 44.

[0055] The working principle of the fourth electric slide rail 42 is to use a motor to provide power, and through a reducer, synchronous belt and ball screw, the rotational motion of the motor is converted into linear motion, which drives the slider on the slide rail to move along the slide rail.

[0056] The fourth electric slide rail 42 is provided with a sliding plate 44 on its top, and a clamping mechanism 43 is provided on the top of the sliding plate 44. When the fourth electric slide rail 42 is started, the fourth electric slide rail 42 can drive the sliding plate 44 and the clamping mechanism 43 to move horizontally as a whole.

[0057] The clamping mechanism 43 is used to clamp the connector 52. The clamping mechanism 43 includes a clamping cylinder and a jaw. The jaw is composed of multiple sets of connecting rods. Under the drive of the clamping cylinder, the jaw can open and close. When the jaw opens, the connector 52 can be released. When the jaw closes, the connector 52 can be clamped.

[0058] Based on the clamping mechanism 43 clamping the connector 52, the connector 52 can be moved horizontally by the fourth electric slide rail 42, which facilitates the docking of the pipe 51 and the connector 52, and further facilitates the normal progress of subsequent welding work.

[0059] In the actual welding process, auxiliary component 3 can be set up to assist the normal welding operation of pipe fitting 51 and connector 52. The specific structure of auxiliary component 3 is as follows:

[0060] See Figure 2 The auxiliary component 3 includes a support base 31, and an auxiliary structure 32 is provided above the support base 31.

[0061] See Figure 3 The auxiliary structure 32 includes a placement seat 321, which is located on the top of the support seat 31. Two sets of auxiliary wheels 322 are symmetrically arranged in the middle of the placement seat 321, and the two sets of auxiliary wheels 322 are rotatably connected to the placement seat 321.

[0062] The combination of the support base 31 and the auxiliary structure 32 can support the pipe 51 and reduce the swaying of the pipe 51 when it is suspended. At the same time, since the pipe 51 is located in the middle of the two sets of auxiliary wheels 322, and the two sets of auxiliary wheels 322 are rotatably connected to the placement base 321, when the pipe 51 and the connecting piece 52 are rotated to adjust their positions, the two sets of auxiliary wheels 322 move with the pipe 51, reducing the displacement difference of the pipe 51 and facilitating the normal progress of welding work.

[0063] Specifically, the robotic arm places the pipe fitting 51 and the connector 52 into the middle positions of the electric chuck 26 and the clamping mechanism 43, respectively. The electric chuck 26 and the clamping mechanism 43 clamp the pipe fitting 51 and the connector 52. Then, the transfer cylinder 22 and the fourth electric slide rail 42 are activated, and the pipe fitting 51 and the connector 52 move towards each other under the drive of the transfer cylinder 22 and the clamping mechanism 43, thereby achieving the docking of the pipe fitting 51 and the connector 52. Then, the first electric slide rail 11, the second electric slide rail 12, and the third electric slide rail 13 are activated. Under the adjustment of the first electric slide rail 11, the second electric slide rail 12, and the third electric slide rail 13, the welding head 15 is aligned with the pipe fitting 51 and the connector 52. Corresponding to the spot welding points, the welding head 15 is started to weld the spot welding points. After the spot welding is completed, the mounting bracket 14 is started. Driven by the third electric slide rail 13, the welding head 15 is moved away from the pipe fitting 51 and the connector 52. The clamping mechanism 43 is started to release the connector 52. The connection between the pipe fitting 51 and the connector 52 is solidified under the drive of the rotary motor 23. The rotation of the position of the pipe fitting 51 and the connector 52 makes it easier to expose the unwelded points. The third electric slide rail 13 is started again to drive the welding head 15 to move down. The welding head 15 is started to continue to weld the pipe fitting 51 and the connector 52. This process is repeated until all the welding points of the pipe fitting 51 and the connector 52 are welded, realizing the ring welding of the pipe fitting 51 and the connector 52.

[0064] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
