Description

Technical Field

[0001] This invention relates to the field of welding technology for the outer cylinder of a level gauge, specifically a circumferential welding device for machining the outer cylinder of a level gauge. Background Technology

[0002] The machining and welding of the outer cylinder of the level gauge is a key process to ensure the performance of the level measurement equipment. During machining, high-quality stainless steel and other materials are selected first, and the outer cylinder body is formed through processes such as cutting and rolling to ensure the roundness and dimensional accuracy of the cylinder body. The welding process is particularly important and is carried out by certified welders in a clean environment. During welding, parameters such as current and welding speed are controlled to avoid defects such as burn-through and porosity, ensuring that the weld is uniform, smooth, and has strong sealing. After welding, pressure resistance testing and non-destructive testing (such as penetrant testing) are required, and the weld is ground and polished to improve corrosion resistance and appearance quality. This process directly affects the measurement accuracy and service life of the level gauge and must be strictly followed in accordance with process specifications. Patent application CN118218862B discloses a liquid level gauge outer cylinder processing equipment, including a base plate, a base frame fixedly connected to the top of the base plate, a rectangular frame on the top of the base frame, an outer cylinder body on the top of the rectangular frame, and flanges on one side and the top of the outer cylinder body. Through the design of the welding mechanism, the outer cylinder body is placed on the top of the rectangular frame. During assembly and welding with the flanges, welding mechanisms on different outer ring plates can be used to weld the ends and outer sides of the outer cylinder body to the flanges respectively. During the welding process, clamping plates clamp and fix the flanges, ensuring they remain in close contact with the outer cylinder body. Then, by controlling the rotation of the inner ring plate, the welding torch can perform circumferential welding on the connection parts. The aforementioned patent features a base plate with a base frame fixedly connected to its top. A rectangular frame is positioned on top of the base frame, and an outer cylinder body is positioned on top of the rectangular frame. Flanges are provided on one side and the top of the outer cylinder body. However, a large amount of fumes are inevitably generated during the welding process. These fumes permeate the welding area, interfering with the operator's vision or affecting the detection accuracy of the automatic welding sensor. This may lead to weld position displacement or reduced welding quality. Conventional fixed exhaust or blowing devices are difficult to effectively and in real-time remove the fumes generated near the welding point during the circumferential welding process while the workpiece is rotating, causing the fumes to accumulate around the workpiece. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a circumferential welding device for machining the outer cylinder of a level gauge, thereby solving the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a circumferential welding device for processing the outer cylinder of a level gauge, comprising a placement frame, a welding component fixedly connected to the top of the placement frame, a power component fixedly connected to the inner top of the placement frame, the top of the power component being rotatably connected to a worktable, and a guide mechanism fixedly connected to the top of the placement frame. The guiding mechanism includes: The slide rail is fixedly connected to the top of the placement frame. The electric slider in the guide mechanism can slide back and forth along the fixed slide rail. This allows the fan, airflow pipe and airflow differential assembly fixed on it to move with the welding process or the position of the workpiece. This dynamic adjustment capability ensures that the airflow guidance and fume adsorption can cover the area above different welding positions of the liquid level gauge outer cylinder on the workbench. This solves the problem of coverage dead angles that may exist in fixed dust removal devices and significantly increases the effective treatment range and treatment efficiency of the equipment for welding fumes. An electric slider, which is slidably connected to the outer wall of the slide rail; The fan is fixedly connected to the outer wall of the electric slider. A guiding mechanism consisting of the fan, airflow pipe, and airflow differential assembly is provided. The equipment can actively generate and guide airflow near the welding point. The airflow generated by the fan blows directly through the airflow pipe to blow the welding fumes away from the welding area. On the other hand, the airflow is introduced into the airflow chambers on both sides. Utilizing Bernoulli's principle, the high-speed airflow in the airflow chamber forms a negative pressure area through the airflow holes on its wall, effectively adsorbing and collecting the fumes in the external space, drawing them into the airflow chamber and finally discharging them. This dual effect significantly reduces the diffusion and settling of welding fumes around the workpiece, reduces the adverse effects of fumes on the welding line of sight and weld quality, and improves the working environment. An airflow differential assembly is fixedly connected to the outer wall of the fan.

[0005] Preferably, the workbench extends through the placement frame and is located at the top of the placement frame, and a heat dissipation component is fixedly connected to the outer wall of the power component.

[0006] Preferably, an airflow pipe is also fixedly connected to the outer wall of the fan.

[0007] Preferably, the airflow differential assembly includes two airflow chambers located on both sides of the worktable, and each airflow chamber has an airflow hole on its outer wall.

[0008] Preferably, a guide block is fixedly connected to the top of the placement rack, and the airflow chamber moves and rubs against the guide block.

[0009] Preferably, an auxiliary mechanism is fixedly connected to the side of the placement rack.

[0010] Preferably, the auxiliary mechanism includes a storage box, which is fixedly connected to the side of the placement frame. A door panel is rotatably connected to the outer wall of the storage box. Both the outer walls of the storage box and the door panel are provided with filter holes. The auxiliary mechanism located on the side of the placement frame, especially the storage box and door panel with filter holes, provides a terminal treatment solution for the welding fumes collected and transported by the guided mechanism. The diameter of the filter holes is designed to be smaller than the diameter of the fume particles, which can effectively intercept the fume particles and collect them in the internal space of the storage box. The door panel design allows the storage box to be easily opened for cleaning and removal of the accumulated fume waste after the welding work is completed.

[0011] Preferably, a limiting block is fixedly connected to the outer wall of the storage box, a limiting rod is slidably connected to the outer wall of the limiting block, and a toggle block is fixedly connected to the outer wall of the limiting rod.

[0012] Preferably, a spring is fixedly connected between the limiting rod and the limiting block. When the airflow differential assembly moves with the electric slider, the vibrating plate fixed thereon periodically contacts and disengages from the actuating block fixed to the outer wall of the storage box. This contact actuates the limiting rod, which slides within the limiting block and is reset by the spring, generating continuous slight vibration. This vibration acts directly on the airflow chamber, effectively reducing the adhesion and accumulation of dust particles on its inner wall and at the airflow holes. On the other hand, the vibration is transmitted to the storage box through the limiting block, helping to prevent the filter holes from clogging. The buffering effect of the spring ensures smooth actuation and avoids jamming. The vibrating plate is fixedly connected to the outer wall of the airflow chamber, and the actuating block is in active contact with the vibrating plate.

[0013] This invention provides a circumferential welding device for machining the outer cylinder of a level gauge. It has the following beneficial effects: 1. This circumferential welding equipment for machining the outer cylinder of a level gauge utilizes a guiding mechanism consisting of a fan, airflow pipes, and an airflow differential assembly. The equipment actively generates and guides airflow near the welding point. The airflow generated by the fan blows directly through the airflow pipes, removing welding fumes from the welding area. Simultaneously, the airflow is guided into airflow chambers on both sides. Utilizing Bernoulli's principle, the high-speed airflow within the chambers creates a negative pressure zone through airflow holes on their walls, effectively adsorbing and collecting fumes from the external space, drawing them into the chambers, and ultimately discharging them. This dual effect significantly reduces the diffusion and settling of welding fumes around the workpiece, minimizing the adverse effects of fumes on the welding line of sight and weld quality, while also improving the working environment.

[0014] 2. The circumferential welding equipment used for processing the outer cylinder of the level gauge can slide back and forth along a fixed slide rail via an electric slider in the guide mechanism. This allows the fan, airflow pipe, and airflow differential assembly fixed on it to move with the welding process or the position of the workpiece. This dynamic adjustment capability ensures that the airflow guidance and fume adsorption can cover the area above different welding positions of the outer cylinder of the level gauge on the workbench, solving the problem of dead corners that may exist in fixed dust removal devices, and significantly increasing the effective treatment range and treatment efficiency of the equipment for welding fumes.

[0015] 3. This circumferential welding equipment for processing the outer cylinder of a level gauge provides a terminal treatment solution for welding fumes collected and transported by the guided mechanism by setting auxiliary mechanisms located on the side of the placement frame, especially storage boxes and door panels with filter holes. The diameter of the filter holes is designed to be smaller than the diameter of the fume particles, which can effectively intercept the fume particles and collect them in the internal space of the storage box. The door panel design allows the storage box to be easily opened for cleaning and removal of accumulated fume waste after the welding work is completed.

[0016] 4. The circumferential welding equipment used for processing the outer cylinder of the level gauge works by periodically contacting and disengaging a vibrating plate fixed to the airflow differential assembly with a moving block fixed to the outer wall of the storage tank when the airflow differential assembly moves with the electric slider. This contact actuates the limit rod, which slides within the limit block and is reset by a spring, generating continuous slight vibration. This vibration acts directly on the airflow chamber, effectively reducing the adhesion and accumulation of dust particles on its inner wall and at the airflow holes. On the other hand, the vibration is transmitted to the storage tank through the limit block, which helps prevent the filter holes from clogging. The buffering effect of the spring ensures smooth actuation and avoids jamming. Attached Figure Description

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0021] Example 1, please refer to Figure 1-6 The present invention provides a technical solution: a circumferential welding device for processing the outer cylinder of a level gauge, comprising a placement frame 1, a welding component 2 fixedly connected to the top of the placement frame 1, a power component 3 fixedly connected to the inner top of the placement frame 1, the top of the power component 3 being rotatably connected to a worktable 4, a guide mechanism 6 fixedly connected to the top of the placement frame 1, the placement frame 1 being set at the required position, the welding component 2 being set on the placement frame 1, the outer cylinder of the level gauge to be welded being placed on the worktable 4, the power component 3 being powered on and started will drive the worktable 4 to rotate, thereby changing the welding position of the outer cylinder of the level gauge, thus achieving circumferential welding of the outer cylinder of the level gauge; Guiding organization 6 includes: Slide rail 61 is fixedly connected to the top of the placement rack 1; Electric slider 62 is slidably connected to the outer wall of slide rail 61; Fan 63 is fixedly connected to the outer wall of electric slider 62; Airflow differential assembly 65 is fixedly connected to the outer wall of fan 63.

[0022] The workbench 4 passes through the placement rack 1 and is located at the top of the placement rack 1. The outer wall of the power unit 3 is fixedly connected to the heat dissipation unit 5. The placement rack 1 is set in the required position, the welding component 2 is set on the placement rack 1, the outer cylinder of the level gauge to be welded is placed on the workbench 4, the power component 3 is powered on and started to drive the workbench 4 to rotate, and then change the welding position of the outer cylinder of the level gauge, thus achieving the circumferential welding of the outer cylinder of the level gauge.

[0023] An airflow pipe 64 is also fixedly connected to the outer wall of the fan 63; When the blower 63 is powered on, it blows air through the airflow pipe 64, which guides the fumes generated during the welding process away, reducing the impact of fumes on welding accuracy.

[0024] The airflow differential assembly 65 includes two airflow chambers 651, which are located on both sides of the workbench 4. Each airflow chamber 651 has an airflow hole 653 on its outer wall.

[0025] A guide block 652 is fixedly connected to the top of the placement rack 1, and the airflow chamber 651 moves and rubs against the guide block 652.

[0026] The blower 63 also blows air into the air chamber 651. The air is discharged from the other end of the air chamber 651. When the air flows in the air chamber 651, the outer wall of the air chamber 651 has an air vent 653. According to Bernoulli's principle, the greater the air velocity, the lower the pressure. Therefore, the air velocity in the air chamber 651 is high. The air velocity outside the air vent 653 is greater than that inside the air chamber 651. So, under pressure, the smoke and dust will be squeezed into the air chamber 651 and then discharged from the other end of the air chamber 651. When the electric slider 62 is powered on, it moves back and forth on the slide rail 61, which in turn drives the fan 63 to move. The movement of the fan changes the position of the airflow pipe 64 and the airflow difference component 65 in treating the dust, thus increasing the treatment of dust in more locations. The airflow chamber 651 is placed on the guide block 652, which restricts the range of motion of the airflow chamber 651.

[0027] Example 2, please refer to Figure 1-8 Based on Embodiment 1, the present invention provides a technical solution: An auxiliary mechanism 7 is fixedly connected to the side of the placement rack 1.

[0028] The auxiliary mechanism 7 includes a storage box 71, which is fixedly connected to the side of the placement rack 1. A door panel 72 is rotatably connected to the outer wall of the storage box 71. Filter holes 73 are provided on the outer walls of both the storage box 71 and the door panel 72.

[0029] A limiting block 77 is fixedly connected to the outer wall of the storage box 71, a limiting rod 76 is slidably connected to the outer wall of the limiting block 77, and a toggle block 75 is fixedly connected to the outer wall of the limiting rod 76.

[0030] A spring 78 is fixedly connected between the limiting rod 76 and the limiting block 77. A vibrating plate 74 is fixedly connected to the outer wall of the airflow chamber 651. The actuating block 75 is in active contact with the vibrating plate 74. The storage box 71 is located on the side of the placement rack 1. The smoke and dust guided by the airflow pipe 64 and the airflow chamber 651 move towards the storage box 71. The filter holes 73 on the storage box 71 and the door panel 72 filter the smoke and dust. The diameter of the filter holes 73 is smaller than the diameter of the smoke and dust. After the work is completed, the smoke and dust stored in the storage box 71 can be taken out by opening the door panel 72; During the movement of the airflow chamber 651, the vibrating plate 74 will move. The vibration plate 74 and the toggle block 75 will move against each other, which will cause the limit rod 76 and the airflow chamber 651 to vibrate, reducing the adhesion of smoke and dust in the airflow chamber 651. The vibration of the limit rod 76 is transmitted to the storage box 71 through the limit block 77, causing the storage box 71 to vibrate. The limit rod 76 and the limit block 77 are slidably connected and set by the spring 78, so that when the toggle block 75 and the vibrating plate 74 are stuck, the spring 78 can elastically buffer.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
