Description

Technical Field

[0001] This utility model relates to the field of welding processing technology, and in particular to an electromagnetic flowmeter welding device. Background Technology

[0002] Electromagnetic flowmeter welding equipment is a specialized device used to connect electromagnetic flowmeter sensors to pipelines. It is mainly used for welding flanges or process connections made of materials such as stainless steel and carbon steel. Welding methods typically include argon arc welding or laser welding, suitable for high-temperature, high-pressure, or corrosive media conditions. Some devices are equipped with cooling systems to prevent damage to the electrodes and lining inside the flowmeter from the high temperatures of welding. After welding, an airtightness test is required to ensure that the sealing performance meets industry standards.

[0003] Electromagnetic flowmeter welding devices are primarily used to reliably connect sensors to pipelines, based on high-precision welding technology. During welding, inert gas shielded welding or laser welding is employed, molten metal at high temperatures to achieve a metallurgical bond while preventing oxidation. Some systems are equipped with temperature monitoring and cooling devices to prevent overheating and damage to internal flowmeter components. After welding, airtightness testing ensures a tight seal, meeting industrial leak-proof requirements. The entire process requires controlled heat input to minimize deformation and guarantee measurement accuracy.

[0004] In existing technologies, some electromagnetic flowmeter welding devices generate spatter during operation. The spatter is hot and fast, and can splash around the equipment, easily damaging surrounding objects. If workers are not adequately protected, the spatter can instantly burn their skin, causing redness, blisters, or even deep burns. Therefore, an electromagnetic flowmeter welding device is proposed to solve the above problems. Utility Model Content

The spatter is hot and fast, and can splash around the equipment, easily damaging surrounding objects. When workers are not adequately protected, the spatter can instantly burn their skin, causing redness, blisters, or even deep burns.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] The outer side of the connecting shaft is rotatably connected to the inside of the frustum, and the upper and lower sides of the four corner blocks are rotatably connected to the inside of the frustum.

[0012] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the protective cover is installed behind the workbench. The starting motor drives the four corner rotating blocks to rotate via the connecting shaft, pushing the moving rod to slide and causing the linkage rod to move outward. The linkage rod causes the support block to expand and fix the cover, while simultaneously compressing the spring to store energy. When the motor is restarted and reversed, the four corner rotating blocks reset, and the spring releases energy to drive each component back to its original position, achieving quick assembly and disassembly. This design effectively blocks welding spatter, sparks, harmful radiation, and dust and moisture, protecting personnel and equipment safety and ensuring stable operation.

[0024] 2. In this utility model, after the work is completed, the electric push rod is started, which drives the connecting block to push the sliding plate to move along the slide rail, so that the sliding column drives the rotating rod to rotate around the Z-shaped rod, thereby adjusting the left and right angle of the air nozzle. The air nozzle sprays air during the swinging process to remove welding slag, debris and dust on the welding arm, ensuring the cleanliness of the welding point and welding arm, and ensuring the welding quality.

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an electromagnetic flowmeter welding device, including a workbench 1. The workbench 1 serves as the basic load-bearing structure of the entire device, providing a platform for the installation and operation of other components, ensuring the stability of each component during operation, and also providing an operating platform for the welding arm 22. Two frustums 2 are fixedly connected inside the workbench 1, and each frustum 2 has a fixing ring 3 fixedly connected to its top. The fixing ring 3 is used to securely mount a motor 4, ensuring that the motor 4 will not shake or shift during operation, thus guaranteeing the stable operation of the motor 4.

[0033] A motor 4 is fixedly connected to the inner side of the fixing ring 3. The motor 4 is the core power source for the disassembly components inside the entire protective cover 24. When the motor 4 starts, its drive end drives the connecting shaft 5 to rotate. The drive end of the motor 4 is fixedly connected to the connecting shaft 5, which transmits the power of the motor 4 to the four corner rotating blocks 6. The bottom end of the connecting shaft 5 is fixedly connected to the four corner rotating blocks 6. Multiple moving rods 7 are slidably connected inside the frustum 2. After the four corner rotating blocks 6 rotate, the moving rods 7 slide along the outer side of the four corner rotating blocks 6. Due to the undulating structure of the four corner rotating blocks 6, the moving rods 7 can retract inward or slide outward, which is a key component for fixing the protective cover 24 to the support block 10.

[0034] Multiple movable rods 7 are fixedly connected to springs 8 on their outer sides. During the installation of the protective cover 24, the springs 8 are compressed, undergo elastic deformation, and store elastic potential energy. During disassembly, the springs 8 release the stored elastic potential energy, causing the movable rods 7 to slide and reset. Multiple movable rods 7 are fixedly connected to their top ends by linkage rods 9, which transmit the movement of the movable rods 7 to the support block 10. The other end of the linkage rod 9 is fixedly connected to the support block 10. A protective cover 24 is installed on the outer side of the support block 10. The protective cover 24 prevents spatter generated by the welding arm 22 during operation from injuring surrounding objects or personnel. The interior of the protective cover 24 is equipped with cleaning components for cleaning spatter from welding equipment.

[0035] Reference Figure 1 , Figure 2 , Figure 4 The cleaning assembly includes a fixing block 11, which is fixedly connected to the inner wall of the protective cover 24. The fixing block 11 provides a stable mounting base for subsequent components such as the electric push rod 12, allowing the entire cleaning assembly to be reliably integrated inside the protective cover 24. The electric push rod 12 is fixedly connected inside the fixing block 11. The electric push rod 12 is the core power component of the cleaning assembly, converting electrical energy into mechanical energy for contraction movement. A connecting block 13 is fixedly connected to the drive end of the electric push rod 12. The connecting block 13 serves as the connection hub between the electric push rod 12 and the sliding plate 14, stably transmitting the power of the electric push rod 12 to the sliding plate 14, ensuring that the sliding plate 14 can move in accordance with the movement of the electric push rod 12. The top of the connecting block 13 is fixedly connected to the sliding plate 14, allowing the sliding plate 14 to move vertically under the drive of the connecting block 13.

[0036] Meanwhile, the sliding rod 15, fixedly connected to the rear bottom end of the sliding plate 14, cooperates with the slide rail 16, allowing the sliding plate 14 to slide horizontally along the slide rail 16. The sliding rod 15 is fixedly connected to the rear bottom end of the sliding plate 14, and the slide rail 16 is slidably connected to the outer side of the sliding rod 15. The sliding rod 15 can slide freely inside the slide rail 16, which provides precise guidance, ensuring the stability of the sliding plate 14 during horizontal movement. A sliding column 17 is slidably connected inside the sliding plate 14, and a rotating rod 18 is fixedly connected to the bottom end of the sliding column 17. The sliding column 17 can slide back and forth inside the sliding plate 14, providing a movable connection point for the rotating rod 18.

[0037] A Z-shaped rod 19 is fixedly connected to the bottom end of the rotating rod 18. The Z-shaped rod 19 transmits power to the air nozzle 20 and drives it to rotate. The air nozzle 20 is fixedly connected to the bottom end of the Z-shaped rod 19. An external pipe 21 is fixedly connected to the other end of the air nozzle 20. The air nozzle 20 is connected to an external air source through the external pipe 21. When the air nozzle 20 reaches the designated cleaning position driven by other components, the external air source delivers high-pressure gas to the air nozzle 20 through the external pipe 21. The air nozzle 20 sprays out the high-pressure gas and uses the impact force of the airflow to blow off the spatter on the surface of the welding equipment.

[0038] Reference Figure 1 , Figure 3 , Figure 4 The outer side of the connecting shaft 5 is rotatably connected to the inside of the frustum 2, forming a stable radial support, so that the driving torque of the motor 4 can be efficiently transmitted to the four corner rotating blocks 6. The upper and lower sides of the four corner rotating blocks 6 are rotatably connected to the inside of the frustum 2. The other end of the spring 8 is fixedly connected to the inside of the frustum 2. The outer side of the four corner rotating blocks 6 is in contact with the side of the moving rod 7 that is close to it. Through the synergistic action of the spring 8 and the four corner rotating blocks 6 on the moving rod 7, the moving rod 7 can slide outward or inward.

[0039] A transparent plate 23 is fixedly connected inside the protective cover 24, allowing operators to clearly observe the equipment's operating status. A welding arm 22 is fixedly connected to the top of the workbench 1; the welding arm 22 is the actuator for welding the electromagnetic flowmeter, and the bottom of the protective cover 24 contacts the top of the workbench 1. A groove is formed inside the sliding plate 14, and the outer side of the sliding column 17 is slidably connected inside the groove, providing the sliding direction and track for the sliding column 17. When the angle of the air nozzle 20 needs to be adjusted, the sliding of the sliding column 17 drives the rotating rod 18 to rotate around the rotation connection point with the fixed block 11, and the rotating rod 18 then drives the Z-shaped rod 19 to rotate.

[0040] The bottom end of the slide rail 16 is fixedly connected to the inside of the fixed block 11, and the bottom end of the sliding plate 14 is slidably connected to the top end of the slide rail 16. The outer side of the Z-shaped rod 19 is rotatably connected to the inside of the fixed block 11. Its rotation changes the orientation and position of the air nozzle 20. The air nozzle 20 is connected to an external air source through an external pipe 21. After reaching the designated cleaning position, high-pressure gas is ejected from the air nozzle 20, using the airflow impact force to blow off the spatter on the surface of the welding equipment, completing the cleaning work. The bottom end of the rotating rod 18 is rotatably connected to the inside of the fixed block 11.

[0041] Working principle: The operator installs the protective cover 24 on the workbench 1 and starts the motor 4. The motor 4 starts moving and drives the connecting shaft 5, which is fixedly connected to its drive end, to move. The movement of the connecting shaft 5 drives the four corner rotating blocks 6 to rotate. The movement of the four corner rotating blocks 6 causes the moving rod 7 to slide along the outside of the four corner rotating blocks 6, so that the moving rod 7 drives the linkage rod 9 to move outward. At the same time, the movement of the moving rod 7 drives the spring 8 to move, causing the spring 8 to undergo elastic deformation and store elastic potential energy. The movement of the linkage rod 9 drives the support block 10 to move outward, thus fixing the protective cover 24. When the motor 4 is started again, the motor 4 drives the four corner rotating blocks 6 to move in the opposite direction. At this time, the force applied to the connecting shaft 5 disappears, the connecting shaft 5 releases elastic potential energy and drives the connected parts to return to their original positions, realizing convenient disassembly of the protective cover 24. The easily disassembled protective cover 24 can effectively block the spatter, sparks and harmful radiation generated during the welding process, protect the safety of the operator and the critical parts of the equipment from damage, extend the service life of the device, and also prevent dust and moisture, reduce the adverse effects of the external environment on the welding device, and ensure the stable operation of the equipment.

[0042] After the work is completed, the electric push rod 12 starts and begins to move, driving the connecting block 13 fixedly connected to its drive end to move. The movement of the connecting block 13 causes the sliding plate 14 to slide on the track of the slide rail 16 via the sliding rod 15. The movement of the sliding plate 14 causes the sliding column 17 to move, causing the rotating rod 18 to rotate around the Z-shaped rod 19 as the axis, realizing the change of the direction of the Z-shaped rod 19. The movement of the Z-shaped rod 19 drives the air nozzle 20 to move left and right, realizing the angle adjustment of the air nozzle 20. While the air nozzle 20 is moving, it blows air to remove the residual welding slag, metal debris and fumes on the welding arm 22, effectively keeping the welding point and welding arm 22 clean and avoiding impurities from affecting the welding quality.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
