Description

Technical Field

[0001] This utility model relates to the field of valve welding technology, and more specifically, to a welding device based on automated valves. Background Technology

[0002] Valves are one of the most widely used fluid control devices. As an important part of the pipeline system, valves come in many specifications and types and have different functions. The manufacturing process of valves directly affects the safe operation of pipeline equipment, and valve welding is one of the key processes in the entire manufacturing process. To accommodate the connection of extra-long rod parts, it is often necessary to weld three parts. During the welding process, if unevenness or protrusions appear in the middle part and are not detected in time, after one end is welded, the weld joint at the other end cannot be welded due to misalignment and needs to be readjusted. During welding, if the centers of two parts are not concentric, the center line will be wavy, which will prevent the subsequent parts from being assembled and affect the later installation. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a welding device based on an automated valve. To achieve the above objectives, this utility model provides a welding device based on an automated valve, including a positioning body. A main rotating wheel is rotatably connected inside the positioning body, and a roller is rotatably arranged inside the positioning body. The main rotating wheel and the roller maintain a gap and do not contact each other, together forming a load-bearing structure for supporting ultra-long rod parts. A welding device is provided on one side of the positioning body; A support assembly is provided on the side of the positioning body away from the welding equipment. The positioning body and the support assembly work together to form a double bracket structure, which is used to radially limit and fix the extra-long rod. An adjustment component is provided at the center position between the positioning body and the support assembly. The adjustment component includes a pre-tightening fastener, which is slidably disposed along the surface of the adjustment component and can move toward the extra-long rod and abut against the surface of the extra-long rod, thereby forming an axial limit on the surface of the extra-long rod. The pre-tightening fastener can rotate synchronously with the rotation of the extra-long rod. A motor is fixedly connected to the end of the main rotating wheel, and the motor shaft at the output end of the motor passes through the inner wall of the positioning body and is connected to the main rotating wheel.

[0004] The main rotating wheel rotates under the drive of the motor, which in turn drives the extra-long rod to rotate, providing stable rotational power for welding. The rollers rotate synchronously with the extra-long rod, which not only help to support the extra-long rod, but also work with the main rotating wheel to ensure that the extra-long rod rotates smoothly and avoids deviation during rotation.

[0005] As a further improvement to this technical solution, the support assembly includes a support frame, which is disposed on one side of the positioning body. The support frame is rotatably connected to two support rollers, and a gap is formed between the two support rollers. The inner wall of the gap is used to support the extra-long rod, so as to cooperate with the positioning body to achieve stable support for the extra-long rod. The other end of the extra-long rod is supported by the support frame and two internal support rollers, forming a double bracket structure in conjunction with the positioning body. This further enhances the radial support capacity of the extra-long rod. The support rollers rotate synchronously with the extra-long rod, providing stable support without interfering with its rotation, thus ensuring the smoothness of welding the extra-long rod.

[0006] As a further improvement to this technical solution, the adjustment assembly includes a connecting frame located between the positioning body and the support assembly. The surface of the connecting frame is provided with a groove. The surface of the pre-tightening fastener slides on the inner wall of the groove. The pre-tightening fastener includes a slide frame slidably connected to the inner wall of the groove. A pre-tightening wheel is rotatably connected inside the slide frame. The surface of the pre-tightening wheel is used to abut against the surface of the extra-long rod so that the rotation of the pre-tightening wheel cooperates with the rotation of the extra-long rod. A lead screw is rotatably connected inside the connecting frame. A knob is fixedly connected to the top of the lead screw. The thread on the surface of the lead screw is threadedly connected to the inner wall of the pre-tightening fastener.

[0007] The pre-tightening fixing component slides along the slide groove through the connecting frame, lead screw, knob and other structures, so that the pre-tightening wheel abuts against the surface of the extra-long rod, thereby achieving axial limit of the extra-long rod. The pre-tightening wheel rotates synchronously with the extra-long rod, which not only ensures the axial limit effect, but also avoids interference with the rotation of the extra-long rod, ensuring that the welding process is smooth.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: In this automated valve-based welding equipment, a double-bracket structure is formed by the positioning body and the support assembly. The main rotating wheel and rollers jointly support the extra-long rod. With the axial limiting of the pre-tightening fixing component in the adjustment assembly, the extra-long rod can be fixed from multiple dimensions, radially and axially. During the welding process, the extra-long rod can rotate stably, effectively avoiding positional displacement caused by welding vibration. This reduces the problem of the center line becoming wavy due to the misalignment of the two parts, ensuring the concentricity of the welded parts and facilitating the connection and installation of related parts later. The structural design of maintaining a gap and not contacting between the main rotating wheel and the rollers allows the device to adapt to extra-long rod parts of different diameters without the need for frequent equipment changes or structural adjustments for different specifications of parts, enhancing the versatility and flexibility of the device. Because the device can ensure stable rotation and precise positioning of the extra-long rod during welding, it can promptly detect any protrusions or unevenness in the intermediate parts. The pre-tightening fixing component rotates synchronously with the extra-long rod without interfering with its rotation. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0013] Please see Figures 1-5 As shown, this embodiment provides a welding device based on an automated valve, including a positioning body 1. A main rotating wheel 10 is rotatably connected inside the positioning body 1, and a roller 11 is rotatably arranged inside the positioning body 1. The main rotating wheel 10 and the roller 11 maintain a gap and do not contact each other, together forming a load-bearing structure for supporting ultra-long rod parts. Welding equipment 2 is installed on one side of the positioning body 1; A support component 3 is provided on the side of the positioning body 1 away from the welding equipment 2. The positioning body 1 and the support component 3 work together to form a double bracket structure, which is used to radially limit and fix the extra-long rod. An adjustment component 4 is provided at the center position between the positioning body 1 and the support component 3. The adjustment component 4 includes a pre-tightening fastener 43. The pre-tightening fastener 43 is slidably disposed along the surface of the adjustment component 4, and can move toward the direction of the extra-long rod and abut against the surface of the extra-long rod, thereby forming an axial limit on the surface of the extra-long rod. The pre-tightening fastener 43 can rotate synchronously with the rotation of the extra-long rod. The extra-long rod to be welded is placed between the main rotating wheel 10 and the roller 11 of the positioning body 1, and at the corresponding bearing position of the support assembly 3. The adjustment assembly 4 is operated so that the pre-tightening fixing part 43 slides along the surface of the adjustment assembly 4 and moves towards the extra-long rod until it abuts against the surface of the extra-long rod. The welding equipment 2 is started and put into a ready-to-work state. At the same time, the main rotating wheel 10 starts to rotate. Since the extra-long rod is placed between the main rotating wheel 10 and the roller 11, the rotation of the main rotating wheel 10 will drive the extra-long rod to rotate accordingly. The roller 11 will also rotate accordingly with the rotation of the extra-long rod. The pre-tightening fixing part 43 rotates synchronously with the rotation of the extra-long rod to avoid interference with the rotation of the extra-long rod. During the stable rotation of the extra-long rod, the welding equipment 2 begins to perform welding operations on the welding part of the extra-long rod.

[0014] The improvement in this embodiment is as follows: Considering the connection of extra-long rod components, which often requires welding three parts, unevenness in the middle parts can occur during welding. If this is not detected immediately, after welding one end, the weld at the other end may fail due to misalignment, requiring recalibration. Furthermore, misalignment between two parts during welding can cause the centerline to become wavy, preventing the assembly of subsequent components and affecting later installation. Therefore, a double-bracket structure is formed between the positioning body 1 and the support assembly 3. The main rotating wheel 10 and roller 11 jointly support the extra-long rod. Combined with the axial limiting of the pre-tightening fixing part 43 in the adjustment assembly 4, the extra-long rod can be fixed from multiple dimensions, radially and axially. During welding, the extra-long rod can rotate stably, effectively avoiding... To prevent positional shifts caused by welding vibrations, the device reduces the problem of wavy centerlines caused by misalignment between two parts, ensuring the concentricity of the welded parts and facilitating the connection and installation of related components later. The structure design that maintains a gap and does not contact between the main rotating wheel 10 and the roller 11 allows the device to adapt to extra-long rod parts of different diameters without the need for frequent equipment changes or structural adjustments for parts of different specifications, enhancing the device's versatility and flexibility. Since the device ensures stable rotation and precise positioning of the extra-long rod during welding, it can promptly detect any protrusions or unevenness in the intermediate parts. The pre-tightening fixing part 43 rotates synchronously with the extra-long rod without interfering with its rotation.

[0015] In order to enable the main rotating wheel 10 to rotate, a motor 12 is fixedly connected to the end of the main rotating wheel 10. The motor shaft at the output end of the motor 12 passes through the inner wall of the positioning body 1 and is connected to the main rotating wheel 10. The operation of the motor 12 can drive the main rotating wheel 10 to rotate, thereby driving the extra-long rod to rotate, so that the roller 11 rotates synchronously.

[0016] In order for the support assembly 3 to cooperate with the positioning body 1 to support the extra-long rod, the support assembly 3 includes a support frame 31, which is disposed on one side of the positioning body 1. The support frame 31 is rotatably connected to two support rollers 32, and a gap is formed between the two support rollers 32. The inner wall of the gap is used to support the extra-long rod, so as to cooperate with the positioning body 1 to achieve stable support for the extra-long rod. One end of the extra-long rod is placed between the main rotating wheel 10 and the roller 11 of the positioning body 1, and the other end is placed in the gap between the two support rollers 32 of the support assembly 3. The inner wall of the gap is in contact with the surface of the extra-long rod, providing support for the extra-long rod. When the extra-long rod rotates with the main rotating wheel 10, the contact between the extra-long rod and the two support rollers 32 will drive the two support rollers 32 to rotate synchronously inside the support frame 31, thereby continuously providing stable support for the extra-long rod without affecting its rotation, and working with the positioning body 1 to ensure the stability of the extra-long rod during the welding process.

[0017] In order to allow the pre-tightening fastener 43 to slide along the inner wall of the adjustment assembly 4, it is necessary to further disclose the parts of the adjustment assembly 4. Therefore, the adjustment assembly 4 includes a connecting frame 41 located between the positioning body 1 and the support assembly 3. The surface of the connecting frame 41 is provided with a groove 410, and the surface of the pre-tightening fastener 43 slides on the inner wall of the groove 410.

[0018] In order to allow the pre-tightening fastener 43 to slide on the inner wall of the slide groove 410, a lead screw 42 is rotatably connected inside the connecting frame 41, a knob 420 is fixedly connected to the top of the lead screw 42, and the thread on the surface of the lead screw 42 is threadedly connected to the inner wall of the pre-tightening fastener 43. The knob 420 on the top of the lead screw 42, which is rotatably connected inside the rotating connecting bracket 41, drives the lead screw 42 to rotate synchronously. Since the thread on the surface of the lead screw 42 is connected to the thread on the inner wall of the pre-tightening fastener 43, the rotation of the lead screw 42 is converted into the linear motion of the pre-tightening fastener 43. Driven by the lead screw 42, the pre-tightening fastener 43 slides along the inner wall of the slide groove 410 and moves toward the direction of the extra-long rod.

[0019] To ensure that the pre-tensioning fastener 43 can rotate in coordination with the rotation of the extra-long rod when it approaches and contacts the rod, the pre-tensioning fastener 43 includes a carriage 430 slidably connected to the inner wall of the slide groove 410. A pre-tensioning wheel 431 is rotatably connected inside the carriage 430. The surface of the pre-tensioning wheel 431 abuts against the surface of the extra-long rod, so that the rotation of the pre-tensioning wheel 431 coordinates with the rotation of the extra-long rod. The carriage 430 slides along the inner wall of the slide groove 410 towards the extra-long rod. As the carriage 430 moves, its internal rotatable connection... The preload wheel 431 gradually approaches the extra-long rod until its surface abuts against the surface of the extra-long rod, thus completing the axial preload positioning of the extra-long rod. During the rotation of the extra-long rod driven by the main rotating wheel 10, since the preload wheel 431 and the surface of the extra-long rod remain in contact, the rotation of the extra-long rod will drive the preload wheel 431 to rotate synchronously inside the carriage 430. This rotational engagement relationship ensures that the preload fixing member 43 applies axial preload force to the extra-long rod to ensure its stability, while not hindering the rotation of the extra-long rod due to its own fixation.

[0020] In practical use, the welding equipment based on automated valves of this utility model places one end of the extra-long rod part to be welded between the main rotating wheel 10 and the roller 11 of the positioning body 1, and the other end in the gap formed by the two supporting rollers 32 in the support assembly 3. The operator rotates the knob 420 on the top of the lead screw 42 in the adjustment assembly 4, causing the lead screw 42 to rotate inside the connecting frame 41. The rotation of the lead screw 42 is converted into the linear sliding of the slide 430 along the inner wall of the slide groove 410 on the surface of the connecting frame 41. The slide 430 moves closer to the extra-long rod, and the preload wheel 431 rotatably connected inside it moves closer until the surface of the preload wheel 431 abuts against the surface of the extra-long rod, completing the welding process. The axial pre-tightening positioning of the extra-long rod is initiated, and the welding equipment 2 is started to be in a ready-to-work state. At the same time, the motor 12, which is fixedly connected to the end of the main rotating wheel 10, is started. The motor shaft at the output end of the motor 12 drives the main rotating wheel 10 to rotate. The rotation of the main rotating wheel 10 causes the extra-long rod to rotate synchronously. The roller 11 rotates along with it due to the friction of the extra-long rod. While the extra-long rod is rotating, it drives the two support rollers 32 in contact with it in the support assembly 3 to rotate synchronously inside the support frame 31. The pre-tightening wheel 431 also rotates synchronously inside the slide 430 under the drive of the extra-long rod. During the process of the extra-long rod rotating in a stable state, the welding equipment 2 is started and welding operations are performed on the welding parts of the extra-long rod.
