Technical Field
[0001] This utility model relates to the field of welding equipment technology, specifically to an automatic tank welding device. Background Technology
[0002] In many industries such as chemical, food, and pharmaceutical, tanks are commonly used storage and reaction equipment, and their welding quality plays a key role in the tank's sealing performance, pressure resistance, and service life.
[0003] However, current tank welding equipment suffers from several problems. First, the level of automation is generally low, requiring manual assistance for tank positioning and manual adjustment of welding angles and speeds during the welding process. This not only increases the labor intensity for workers but also makes human error highly susceptible to unstable welding quality, resulting in uneven welds and incomplete welds. Second, the applicable range is narrow; existing equipment often only supports welding tanks of specific sizes. When welding tanks of different diameters and lengths, numerous tooling fixtures need to be changed, making the adjustment process cumbersome and time-consuming, severely impacting production efficiency. Third, welding accuracy is poor. Due to the lack of effective positioning and clamping mechanisms, the tank is prone to displacement or shaking during welding, causing weld misalignment and failing to meet the requirements of high-precision welding.
[0004] Therefore, it is necessary to design an automatic tank welding device to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this utility model is to provide an automatic tank welding device to solve the problems of low automation, limited applicability, and insufficient welding precision in the existing tank welding process, so as to achieve efficient, precise and convenient operation of tank welding.
[0006] To achieve the above objectives, this utility model provides the following technical solution: An automatic tank welding device includes a welding platform, a control device, a tank clamping assembly, a vertical adjustment assembly, and a welding assembly.
[0007] Furthermore, the welding platform serves as the basic support structure for the entire device, providing an installation carrier for each component and ensuring the overall stability of the device.
[0008] Furthermore, the control device is fixedly installed on the top of the welding platform and electrically connected to the tank clamping assembly and the welding assembly, respectively. It is used to receive operation commands and control the coordinated operation of each component. The control device is equipped with control buttons and a touch screen display, allowing operators to input welding parameters through the control buttons and touch screen display, enabling convenient control and real-time monitoring of the welding process.
[0009] Furthermore, the tank clamping assembly is located above the welding platform and is used for positioning and clamping the tank to be welded. It includes a clamping cylinder, an annular clamping mold, a guide rail, a guide slide rod, a locking platform, a damping and shock-absorbing mechanism, and an end plate. The telescopic end of the clamping cylinder is fixedly connected to the rear side of the annular clamping mold. The left and right sides of the bottom of the annular clamping mold are slidably connected via corresponding sliders and the guide rail. A guide slide rod is fitted onto the center of the bottom of the annular clamping mold. Through the dual guiding action of the guide rail and the guide slide rod, the annular clamping mold moves smoothly under the drive of the clamping cylinder. The locking platform is located at the end of the guide rail, and the side furthest from the annular clamping mold is fixedly installed on the welding platform via an end plate on the same side. The damping and shock-absorbing mechanism is located between the locking platform and the end plate on the same side. This mechanism includes a damper and a shock-absorbing spring, both positioned between the locking platform and the end plate. It provides buffering and shock absorption during tank clamping, preventing excessive clamping force from damaging the tank.
[0010] Furthermore, the vertical adjustment component is located on one side of the tank clamping component and is used to adjust the vertical height of the welding component. It includes an adjusting handwheel, a ball screw, a limiting slide rod, a screw nut, and a support base. The bottom of the support base is connected to the welding platform, the top of the ball screw is connected to the output end of the adjusting handwheel, the bottom of the ball screw is rotatably connected to the top of the support base, the screw nut is engaged with the ball screw, and the left and right sides of the screw nut are slidably engaged with the limiting slide rod. By rotating the adjusting handwheel, the ball screw is rotated, causing the screw nut to move up and down along the ball screw and the limiting slide rod, thereby achieving precise adjustment of the welding component height.
[0011] Furthermore, the welding assembly is mounted on the vertical adjustment assembly and is used for welding operations on the tank body. It includes a welding head, a connecting wire, and welding equipment. The welding head is detachably mounted on the vertical adjustment assembly, facilitating the replacement of different types of welding heads according to welding requirements. The input end of the welding head is electrically connected to the output end of the welding equipment via the connecting wire, and the welding equipment provides the welding head with the energy and materials required for welding.
[0012] This invention achieves automated control of the tank welding process by coordinating the operation of the tank clamping assembly and the welding assembly through a control device, and by combining the vertical adjustment assembly for precise adjustment of the welding position, effectively improving welding efficiency and welding quality.
[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through the provision of an automatic tank welding device, achieves the following effects: 1. By electrically connecting the control device to the tank clamping assembly and the welding assembly, the device can automatically control the clamping of the tank and the movement of the welding assembly, eliminating the need for excessive manual intervention, reducing the labor intensity of workers, ensuring stable welding quality, and reducing problems such as uneven welds and incomplete welds; the control device is equipped with control buttons and a touch screen display, facilitating the input of welding parameters by operators, making operation simple and intuitive, reducing operational difficulty, and enabling workers to quickly learn and use it; 2.

The tank clamping assembly, through structures such as clamping cylinders and ring clamping molds, effectively positions and clamps the tank, preventing displacement or shaking of the tank during welding, ensuring accurate weld position, and meeting the requirements of high-precision welding; 4. The damping and shock absorption mechanism in the tank clamping assembly can play a buffering role during the tank clamping process, avoiding excessive clamping force from damaging the tank or device, and improving the stability and safety of the device.

[0017] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are provided. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete. Example 1
[0018] Please see Figure 1 This embodiment provides a basic automatic tank welding device, which includes a welding platform 1, a control device 2, a tank clamping assembly 3, a vertical adjustment assembly 4, and a welding assembly 5. The components work together to achieve automatic welding of the tank. Example 2
[0019] Please see Figure 1 Based on Example 1, this embodiment further specifies that the welding platform 1 is made of Q235 low carbon steel plate and has a rectangular plate structure to enhance the stability of the device when it is placed and avoid the welding accuracy being affected by the shaking of the platform during the welding process. The welding platform 1 serves as the basic support carrier of the entire device and provides a stable installation reference for the control device 2, the tank clamping assembly 3, and the vertical adjustment assembly 4. Example 3
[0020] Please see Figure 2 Based on Embodiment 1, this embodiment further specifies that the control device 2 is fixedly installed on one side edge of the top of the welding platform 1 by bolts. The outer shell of the control device 2 is made of ABS engineering plastic, which has certain dustproof and splashproof functions. The control device 2 is electrically connected to the clamping cylinder 31 in the tank clamping assembly 3 and the welding equipment 53 in the welding assembly 5 through the connecting wire 52, which can realize the linkage control of the clamping action and the welding action. At the same time, the control device 2 integrates control buttons and a touch screen. The operator can input welding parameters such as welding current, welding voltage, and welding speed through the touch screen, and can also realize the start, stop, and emergency stop of the device through the control buttons. The touch screen can also display the working status of each component in real time, which is convenient for the operator to monitor. Example 4
[0021] Please see Figure 4This embodiment, based on embodiment 1, further defines the tank clamping assembly 3 as located in the central area above the welding platform 1. It is used to position and clamp the tank to be welded, preventing displacement during welding. It includes a clamping cylinder 31, an annular clamping mold 32, a guide rail 33, a guide slide rod 34, a locking platform 35, a damping and shock absorption mechanism 36, and an end plate 37. The clamping cylinder 31 is a standard double-acting cylinder, its cylinder body fixed to the welding platform 1 by a cylinder bracket. The telescopic end of the clamping cylinder 31 is fixedly connected to the rear center of the annular clamping mold 32 via a flange. A high-temperature resistant rubber pad is pasted on the inner wall of the annular clamping mold 32, and the surface of the rubber pad has anti-slip textures. This prevents scratches on the tank surface during clamping and enhances the friction between the pad and the tank, improving clamping stability. Slider blocks are welded to the left and right sides of the bottom of the annular clamping mold 32. The sliders slide in cooperation with the guide rail 33 fixed to the welding platform 1. Extending axially along the tank body, the annular clamping mold 32 has a sliding hole at the bottom center. The sliding hole is fitted onto the outside of the guide slide rod 34. The guide slide rod 34 is parallel to the guide rail 33 and its two ends are fixed to the welding platform 1 by brackets. Through the dual guidance of the guide rail 33 and the guide slide rod 34, the annular clamping mold 32 is ensured to move smoothly in a straight line under the drive of the clamping cylinder 31. The clamping platform 35 has an L-shaped plate structure. Its horizontal section is fixed to the end of the guide rail 33 by bolts, and its vertical section faces the annular clamping mold 32 for contact and positioning with the end of the tank body. The end plate 37 is a rectangular steel plate, fixed to the welding platform 1 by bolts and located on the side of the clamping platform 35 away from the annular clamping mold 32. A damping and shock absorption mechanism 36 is disposed between the clamping platform 35 and the end plate 37. It includes a damper and a shock-absorbing spring. The two ends of the damper are respectively hinged to the vertical section of the clamping platform 35 and the end plate 37 by pins. The shock-absorbing spring is sleeved on the outside of the damper. When the annular clamping mold 32 pushes the tank to move towards the clamping platform 35 and abuts against it, the damper and the shock-absorbing spring can buffer the impact force of the tank on the clamping platform 35, and prevent the tank or the clamping platform 35 from being damaged by rigid collision. Example 5
[0022] Please see Figure 3Based on Embodiment 1, this embodiment further specifies that the vertical adjustment component 4 is disposed on one side of the tank clamping component 3, and is used to adjust the vertical height of the welding component 5 to adapt to the welding requirements of tanks with different diameters. It includes an adjusting handwheel 41, a ball screw 42, a limiting slide rod 43, a screw nut 44, and a bearing seat 45. The bearing seat 45 consists of a base and a top bearing seat. The base is fixedly connected to the welding platform 1 by bolts, and a deep groove ball bearing is installed inside the bearing seat. The bottom of the ball screw 42 is rotatably connected to the top bearing seat of the bearing seat 45 via a bearing, and the top of the ball screw 42 is fixedly connected to the output end of the adjusting handwheel 41 via a flat key. The outer circumference of the adjusting handwheel 41 is provided with a rubber anti-slip sleeve for easy rotation and adjustment by the operator. The screw nut 44 is connected to the ball screw 42 by a threaded engagement. Sliding holes are opened on the left and right sides of the screw nut 44, and a limiting slide rod 43 is fitted inside the sliding holes. The two ends of the limiting slide rod 43 are fixedly connected to the base and the top bearing seat of the bearing seat 45, respectively, and the limiting slide rod 43 is arranged parallel to the ball screw 42. When the adjusting handwheel 41 is rotated... At this time, the ball screw 42 drives the screw nut 44 to move up and down along the ball screw 42 and the limit slide 43 to achieve vertical position adjustment. Example 6
[0023] Please see Figure 2 Based on Embodiment 1, this embodiment further defines the welding assembly 5: it is set on the vertical adjustment assembly 4 and used to realize the welding operation of the tank. It includes a welding head 51, a connecting line 52, and a welding device 53. The welding head 51 is a gas metal arc welding torch. The tail of the welding head 51 is fixedly connected to the lead screw nut 44 in the vertical adjustment assembly 4 through a detachable structure. The detachable structure makes it easy to replace different models of welding heads 51 according to welding requirements. The welding device 53 is a corresponding gas metal arc welding machine, placed on one side of the welding platform 1 or at a designated external position. The input end of the welding head 51 is electrically connected to the output end of the welding device 53 through the connecting line 52. Under the control of the control device 2, the welding device 53 provides welding wire, shielding gas, and welding power to the welding head 51 to realize the welding operation.
[0024] The working process of this utility model is as follows: When using the automatic tank welding device, the operator first confirms the status of each component: checking whether the welding platform 1 is stable, whether the touch screen and control buttons of the control device 2 respond normally, whether the extension and retraction function of the clamping cylinder 31 in the tank clamping assembly 3 and the smooth sliding cooperation between the guide rail 33 and the slider are smooth, whether the rotation flexibility of the adjusting handwheel 41 in the vertical adjustment assembly 4 and the normal cooperation between the ball screw 42 and the screw nut 44 are normal, whether the connection between the welding head 51 and the connecting line 52 in the welding assembly 5 is firm, and whether the welding equipment 53 is in standby mode. After ensuring that each component is fault-free, proceed to the next step. Then, the operator places the tank to be welded between the annular clamping mold 32 and the clamping table 35 of the tank clamping assembly 3, adjusts the position of the tank so that the axial direction of the tank is consistent with the extension direction of the guide rail 33, and the end of the tank faces the vertical section of the clamping table 35, preparing for subsequent clamping and positioning. The operator then controls the device 2... The welding parameters, including welding current, welding voltage, and welding speed, are input into the touch screen. (For Example 2, preset welding parameters for the same tank specification can be directly called without re-entering.) After setting the parameters, the parameters are confirmed to be correct via the control button and the device enters the standby state. After pressing the start button of the control device 2, the control device 2 sends an action signal to the clamping cylinder 31 of the tank clamping assembly 3. After receiving the signal, the clamping cylinder 31 extends and pushes the annular clamping mold 32 to move smoothly along the guide rail 33 and guide slide rod 34 towards the clamping platform 35. Until the annular clamping mold 32 is in contact with the outer wall of the tank, the tank is clamped between the annular clamping mold 32 and the clamping platform 35. At this time, the damping and shock absorption mechanism 36 (including damper and shock absorption spring) between the clamping platform 35 and the end plate 37 plays a buffering role to avoid rigid collision damage between the tank and the clamping platform 35. After the clamping action is completed, the control device 2 receives the clamping in place signal, and then the operator rotates the vertical adjustment assembly 4. The adjusting handwheel 41 drives the ball screw 42 to rotate. Since the screw nut 44 cooperates with the ball screw 42 and is limited by the limiting slide rod 43, the screw nut 44 moves up and down along the ball screw 42 and the limiting slide rod 43. The welding head 51 of the welding assembly 5 connected to the screw nut 44 moves synchronously with the screw nut 44 until the nozzle of the welding head 51 is aligned with the welding position of the tank. After the welding head 51 is in position, the operator issues a welding start command through the control button of the control device 2. The control device 2 sends a working signal to the welding equipment 53 of the welding assembly 5, the welding equipment 53 starts, and supplies welding wire, shielding gas, and welding energy to the welding head 51 through the connecting line 52.Welding head 51 begins welding the tank body; simultaneously, the operator monitors the welding status (such as welding parameters and welding progress) in real time via the touch screen display of control device 2. When the welding operation is completed (triggered by a preset welding time or limit switch), control device 2 sends a stop signal to welding equipment 53, which stops working, and welding head 51 stops outputting; subsequently, control device 2 sends a reset signal to clamping cylinder 31, which retracts, causing the annular clamping mold 32 to move in the opposite direction along guide rail 33 and guide slide rod 34, releasing the tank body; the operator removes the welded tank body from between the annular clamping mold 32 and the clamping table 35, completing a single welding process.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
