Description

Technical Field

[0001] This utility model relates to the technical field of pressure vessel welding machines, specifically a multi-functional pressure vessel welding machine that facilitates quick replacement of welding torches. Background Technology

[0002] A pressure vessel is a sealed container that can withstand pressure. Pressure vessels have a wide range of applications and play an important role in many sectors such as industry, civil use, military industry, and scientific research. When manufacturing pressure vessels, the vessel body and the cover need to be welded together. During the welding process, the two are in a sealed state. Pressure vessel welding machines are required during the welding process.

[0003] The prior art, disclosed in CN222843379U, provides a metal pressure vessel welding device, relating to the field of welding equipment technology. This invention includes a base, a rotating mechanism on the surface of the base, a controller fixedly mounted on the top surface of the base, and a fixing component fixedly mounted on the top surface of the rotating part of the rotating mechanism, which is used to fix the metal pressure vessel. This invention places the metal pressure vessel to be welded on the top surface of the rotating mechanism, fixes it using the fixing component, and adjusts the position of the welding head to the welding point of the metal pressure vessel using a primary and secondary adjustment mechanism, aligning the welding head with the weld seam. Welding is then performed on the metal pressure vessel via the welding head. Simultaneously, the rotating mechanism drives the metal pressure vessel on top to rotate at a uniform speed, thereby achieving uniform welding of the metal pressure vessel via the welding head.

[0004] In the aforementioned patent, the pressure vessel to be welded is secured using fixing components on both sides. However, this method of securing the pressure vessel can only be used on pressure vessels that have already been basically secured. This results in the need for additional fixing devices to secure the two components to be welded before welding can proceed, making the entire welding process cumbersome and reducing the practicality of the metal pressure vessel welding device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-functional pressure vessel welding machine that facilitates quick and easy replacement of welding torches, thus solving the aforementioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional pressure vessel welding machine that facilitates quick torch replacement, comprising a clamping assembly for fixing and rotating a lower pressure vessel, a welding assembly for supporting and welding the pressure vessel fixedly connected above the clamping assembly, a controller fixedly installed on one side of the welding assembly, and an upper clamping assembly for holding the upper pressure vessel fixedly installed at the end of the welding assembly away from the clamping assembly. The upper clamping assembly includes a vertically movable top plate, with a placement slot for storing the upper pressure vessel at its center. Multiple opposing movable components are movably mounted on the top plate, used to centrally fix the upper pressure vessel. This centralized fixing of the upper pressure vessel by the movable components allows the multi-functional pressure vessel welding machine to fix two pressure vessels to be welded together, improving its practicality.

[0007] Furthermore, the upper clamping assembly includes a hydraulic cylinder fixedly mounted on the welding assembly. The hydraulic cylinder is connected to the controller. The top plate is fixedly mounted on the telescopic end of the hydraulic cylinder. A first motor is fixedly mounted on one side of the top plate. The control box of the first motor is electrically connected to the controller. A bidirectional lead screw is fixedly connected to the output end of the first motor. Multiple movable components are respectively installed in different threaded grooves of the bidirectional lead screw. An auxiliary shaft is fixedly mounted on the side of the top plate away from the bidirectional lead screw. The movement limit of the movable components is installed within the auxiliary shaft. The movement limit of the movable components is installed within the auxiliary shaft, so that the movement of the movable components is directly limited by the auxiliary shaft, improving the accuracy of the internal structure movement of the multi-functional pressure vessel welding machine that facilitates quick welding torch changes.

[0008] Furthermore, the movable component includes movable plates on both sides, located on a bidirectional lead screw and an auxiliary shaft, respectively. A fixed shaft is fixedly installed at the center of the movable plate, and an arc plate for conforming to the upper pressure vessel is fixedly installed on the fixed shaft. The arc plate is located within a placement slot. The arc plate's location within the placement slot allows for more stable fixation of the upper pressure vessel stored in the slot, improving the stability of the upper pressure vessel fixation in the multi-functional pressure vessel welding machine, which facilitates quick welding torch changes.

[0009] Furthermore, the rotary clamp assembly includes a base plate, on which a second motor is fixedly mounted at one end near the welding assembly. The control box of the second motor is electrically connected to the controller. A turntable is fixedly mounted on the output shaft of the second motor. The pressure vessel below is located at the center of the turntable. The central axis of the turntable and the central axis of the placement slot are on the same straight line. Sub-controllers are fixedly mounted on both sides of the turntable. The sub-controllers are remotely connected to the controller. A first electric push rod is fixedly mounted on one opposite end of each of the multiple sub-controllers. The first electric push rod is electrically connected to the sub-controller. A clamping plate for clamping the pressure vessel below is fixedly mounted on the end of the first electric push rod away from the sub-controller.

[0010] Furthermore, the welding assembly includes a support plate, a slide rail fixedly mounted on one side of the support plate, a nylon cloth covering the outer surface of the slide rail, a hollow movable plate movably mounted on the slide rail, and a second electric actuator fixedly mounted on the upper end of the hollow movable plate. The second electric actuator is electrically connected to the controller. This electrical connection allows the controller to directly control the second electric actuator, enhancing the intelligence of the multi-functional pressure vessel welding machine, which facilitates quick welding torch replacement.

[0011] Furthermore, a support frame is fixedly installed at the telescopic end of the second electric actuator. A gun barrel is provided at the end of the support frame away from the second electric actuator. A welding head for welding is fixedly installed at the end of the gun barrel near the pressure vessel. A shaft is fixedly installed at the top of the support frame. A swing bar is oscillatingly connected to the shaft. A fixing member is detachably installed at the end of the swing bar away from the shaft. The fixing member is used to fix the support frame. A screw for pressing down and fixing the gun barrel is movably installed at the center of the top of the swing bar.

[0012] Furthermore, multiple rubber rods are fixedly installed at the end of the arc plate away from the fixed axis. This increases the frictional force between the movable components and the upper pressure vessel, improving the stability of the multi-functional pressure vessel welding machine for quickly changing welding torches.

[0023] Example

The clamping assembly 4 includes a base plate 41. A second motor 42 is fixedly mounted on one end of the base plate 41 near the welding assembly 2.

The pressure vessel below is located at the center of the turntable 46. The central axis of the turntable 46 is on the same straight line as the central axis of the placement groove 15. Sub-controllers 43 are fixedly mounted on both sides of the turntable 46. The sub-controllers 43 are remotely connected to the controller 3. A first electric actuator 45 is fixedly mounted on one opposite end of each of the multiple sub-controllers 43. The first electric actuator 45 is electrically connected to the sub-controllers 43. A clamping plate 44 for holding the pressure vessel below is fixedly installed at the end of the component 5 away from the controller 43. The welding assembly 2 includes a support plate 21. A slide rail 223 is fixedly installed on one side of the support plate 21. Nylon cloth is provided on the outer surface of the slide rail 223.

[0025] The working principle of controller 3 can be divided into four basic steps: input, processing, output, and feedback. First, controller 3 receives input signals from external devices or users, such as button presses or sensor detection information. Next, controller 3 processes the input signals, performs calculations and judgments according to the set algorithms and logic, and then generates corresponding output signals based on the processing results to control the working status and display information of external devices. Since both controller 3 and sub-controller 43 have microcontroller chips and Bluetooth modules, and controller 3 and sub-controller 43 are remotely connected via Bluetooth, and because all the electronic components inside the multi-functional pressure vessel welding machine that facilitates quick welding torch replacement are electrically connected to controller 3 or sub-controller 43, controller 3 can control all the electronic components inside the multi-functional pressure vessel welding machine that facilitates quick welding torch replacement, thus improving the intelligence of the operation of the multi-functional pressure vessel welding machine that facilitates quick welding torch replacement.

[0026] It should be noted that the electrical components and control components in this application are all connected to an external controller and are all existing technologies. This application has not improved them and does not affect the integrity of this application. Furthermore, the parts not involved or not disclosed in detail are the same as or implemented using existing technologies.

[0027] The welding head 234 and the barrel 236 together form a welding torch. The welding torch operates on the principle of combustion, controlling fuel ignition to produce a directional flame. Utilizing the high current and high voltage of the welding machine, heat is concentrated at the torch tip, melting the welding wire. The molten wire penetrates the area to be welded, and after cooling, the welded objects are firmly joined together. This multi-functional pressure vessel welding machine, which allows for quick torch replacement, only requires the welding head 234 and barrel 236 to be activated to weld objects at the end of the welding head 234.

[0028] The screw 232 penetrates the swing bar 233. Therefore, when the screw 232 rotates, it moves downward and eventually fixes the barrel 236. When the user needs to replace the welding gun, he only needs to remove the fixing piece 231 from the support frame 235, and then swing the swing bar 233 to place the new welding gun in the support frame 235 and press it down to fix it. This makes it easier and faster for the user to replace the welding gun.

[0029] Since the outer surface of the slide rail 223 is made of frictional nylon cloth, the hollow movable plate 221 can be directly fixed in that position after sliding on the slide rail 223. This makes the hollow movable plate 221 more firmly located in the sliding position after sliding, improving the practicality of the multi-functional pressure vessel welding machine that facilitates quick replacement of welding torches.

[0030] The outer support frame 235 for fixing the welding torch is directly fixed to the second electric push rod 224. Therefore, the user can quickly adjust the welding position of the welding torch by sliding the hollow movable plate 221 in the slide rail 223 and by extending and retracting the second electric push rod 224. This improves the adjustability of the internal components of the multi-functional pressure vessel welding machine, which facilitates quick replacement of the welding torch.

[0031] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the multi-functional pressure vessel welding machine, which facilitates quick torch replacement, are threaded. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the figure. When using the multi-functional pressure vessel welding machine, the user places the lower pressure vessel to be welded on the turntable 46 and uses the first electric push rod 45 to extend the clamping plate 44 for center clamping. The user aligns the upper pressure component with and places it against the lower pressure vessel. At this time, the upper pressure component is in the placement slot 15. The user starts the first motor 13 to rotate the bidirectional lead screw 14, causing the two movable components 16 to move closer together. At this time, the arc... Plate 164 and rubber rod 163 clamp the pressure vessel. Then, the user starts the welding head 234 and the gun barrel 236 to perform center foundation welding on the upper and lower pressure vessels. After the two can be fixed in place, the user starts the second motor 42 to make the welding head 234 and the gun barrel 236 perform center circumferential welding on the upper and lower pressure vessels. Through the cooperation of the above structure, the multi-functional pressure vessel welding machine that facilitates quick welding gun replacement can not only complete the entire welding process of two pressure vessels, but also quickly replace and fix the welding gun without the need for other external fixing equipment to fix the foundation first, thus improving the practicality and versatility of the multi-functional pressure vessel welding machine that facilitates quick welding gun replacement.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
