In industrial production, they are used to hold and transport chemical raw materials and coolants; in medical equipment, they serve as containers for storing and transporting pharmaceutical solutions and dialysis fluids; in laboratory research, they are used to store and distribute various experimental reagents; and in electronics manufacturing, they are used to store and transport special liquids such as etching solutions and cleaning solutions. Currently, the practical application of fluid manifold tank welded components typically requires the following technologies:

[0003] 1. Suitable welding materials must be compatible with the main material of the hydraulic tank to ensure welding strength and corrosion resistance;

[0004] 2. Advanced welding processes, such as argon arc welding and laser welding for metal materials, and hot plate welding and ultrasonic welding for plastic materials, ensure weld quality and sealing.

[0005] 3. High-precision machining technology ensures accurate dimensional accuracy and fit of welded parts;

[0007] 5. Excellent surface treatment technology enhances the corrosion resistance and aesthetics of welded parts.

[0008] Currently, various equipment and methods are employed to realize the functionality of welded components in hydraulic system tanks. Some manufacturers use traditional manual welding equipment, where welders rely on experience and skill to weld components using handheld welding torches. Other manufacturers use automated welding equipment, where welding paths and parameters are pre-programmed, and robotic arms drive welding torches to improve welding efficiency and consistency. Still others use robotic welding systems, leveraging the high precision and flexibility of robots to weld complex shapes and positions.

[0009] However, the above method has a prominent hardware structure problem. When manually welding, positioning the external thread base and the housing plate often relies on multiple manual measurements, markings, and adjustments. This operation is cumbersome and time-consuming. The positioning achieved by manual operation often requires multiple position adjustments, which takes a long time and affects the subsequent overall processing flow. Utility Model Content

[0010] To address the shortcomings of existing technologies, this utility model provides a welded component for a hydraulic circuit tank, which solves the problem that in manual welding operations, positioning the external threaded base and the tank plate often relies on multiple manual measurements, markings, and adjustments, which is cumbersome and time-consuming. In other words, the positioning achieved by manual operation often requires multiple position adjustments, which is time-consuming and affects the subsequent overall processing flow.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A welded component for a liquid circuit tank includes a rectangular mounting plate. The outer surface of the rectangular mounting plate is provided with a fixing mechanism for adhesion and adsorption. The fixing mechanism includes two round rods and two rubber suction cups. The two round rods are fixedly connected to the outer surface of the rectangular mounting plate, and the two rubber suction cups are threadedly connected to the outer surfaces of the two round rods. The outer surface of the rectangular mounting plate is provided with a quick-positioning sleeve mechanism. The sleeve mechanism includes two T-shaped arc-shaped mounting blocks and a notched ring. The two T-shaped arc-shaped mounting blocks are fixedly connected to the outer surface of the rectangular mounting plate, and the notched ring is rotatably connected to the outer surfaces of the two T-shaped arc-shaped mounting blocks. A handle is fixedly connected to the outer surface of the rectangular mounting plate.

[0013] Preferably, the notched annulus has a T-shaped groove inside.

[0014] Preferably, the outer surfaces of the two rubber suction cups are provided with a housing plate.

[0015] Preferably, the outer surface of the housing plate is fixedly connected to an external threaded base.

[0016] Preferably, the outer surface of the external threaded base is threaded with a valve.

[0017] Preferably, a set of reinforcing pads is provided on the outer surface of the box panel, and a horizontal plate is provided on the outer surface of the box panel.

[0018] Preferably, an internally threaded mounting seat is fixedly connected to the outer surface of the cross plate, and a Z-shaped rotating block is rotatably connected inside the internally threaded mounting seat.

[0019] Preferably, the internal threaded mounting base and the Z-shaped rotating block are internally threaded with a threaded rod, and the threaded rod is internally rotatably connected with a U-shaped abutment plate.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Align the center of the notched ring with the center of the inlet / outlet opening on the housing plate, then align the external threaded base with the center of the notched ring. Use the notch of the notched ring to perform preliminary welding positioning of the external threaded base. After preliminary positioning, screw the notched ring to adjust the position of the notch. Perform preliminary welding positioning of the external threaded base at multiple points in different positions. After completing multi-point positioning, remove the rectangular mounting plate as a whole. At this point, the external threaded base and the housing plate are stably attached, and the weld can be completed. This achieves rapid welding positioning of the external threaded base on the housing plate. The whole process is smooth, avoiding the trouble of repeatedly adjusting the position or repositioning, reducing the time wasted due to positioning operations, and enabling efficient and continuous welding work, thus speeding up the welding and installation process of the external threaded base on the housing plate.

[0022] 2. By screwing the threaded rod, the threaded transmission pushes the U-shaped contact plate to slide along the slide rail on the surface of the horizontal plate, so that the two U-shaped contact plates slide and press against the reinforcing pads at both ends. This limits the reinforcing pads during welding, ensuring accurate welding position and enhancing welding effect. If the U-shaped contact plate is too far from the reinforcing pad, the Z-shaped rotating block can be pulled to rotate, so that the threaded rod loses its upper limit. At this time, the threaded rod can be quickly pushed to slide, so that the U-shaped contact plate can quickly approach the reinforcing pad, achieving the purpose of convenient operation.

Detailed Implementation

[0029] This application provides a welding component for a hydraulic tank, effectively solving the problem of cumbersome and time-consuming manual positioning of the threaded base and the tank plate during manual welding. This often requires multiple manual measurements, markings, and adjustments, hindering the subsequent processing. The solution involves aligning the center of the notched ring with the center of the inlet / outlet opening on the tank plate, then inserting the threaded base into the center of the notched ring. The notch in the ring is used for initial welding positioning. After initial positioning, the notched ring is screwed to adjust the notch position, allowing for multi-point initial welding positioning of the threaded base at different locations. After multi-point positioning, the rectangular mounting plate is removed, resulting in a stable fit between the threaded base and the tank plate, completing the weld. This achieves rapid welding positioning of the threaded base on the tank plate, a smooth process that avoids repeated adjustments or repositioning, reduces time wasted on positioning operations, and enables efficient and continuous welding, accelerating the welding and installation process of the threaded base on the tank plate.

[0030] Example

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that in manual welding operations, positioning the external thread base and the housing plate often relies on multiple manual measurements, markings, and adjustments, which is cumbersome and time-consuming. That is, the positioning achieved by manual operation often requires multiple position adjustments, and the positioning process is time-consuming, affecting the subsequent overall processing flow. The overall idea is as follows: A hydraulic tank welding component includes a rectangular mounting plate 11. The outer surface of the rectangular mounting plate 11 is provided with a fixing mechanism for adhesion and adsorption. The fixing mechanism includes two round rods 12 and two rubber rods 13. The rubber suction cup 13 and two round rods 12 are fixedly connected to the outer surface of the rectangular mounting plate 11. The two rubber suction cups 13 are threaded to the outer surfaces of the two round rods 12 respectively. The outer surface of the rectangular mounting plate 11 is provided with a quick positioning sleeve mechanism, which includes two T-shaped arc-shaped mounting blocks 14 and a notched ring 15. The two T-shaped arc-shaped mounting blocks 14 are fixedly connected to the outer surface of the rectangular mounting plate 11, and the notched ring 15 is rotatably connected to the outer surface of the two T-shaped arc-shaped mounting blocks 14. A handle rod 16 is fixedly connected to the outer surface of the rectangular mounting plate 11, and the notched ring 15 is internally open. A T-shaped groove 17 is provided, and two T-shaped arc-shaped mounting blocks 14 are both set inside the T-shaped groove 17. A housing plate 18 is provided on the outer surface of two rubber suction cups 13. An external threaded base 19 is fixedly connected to the outer surface of the housing plate 18. The external threaded base 19 is set inside the notched ring 15. When welding the external threaded base 19 onto the surface of the housing plate 18, the center of the notched ring 15 is aligned with the center of the inlet and outlet opening of the housing plate 18. The rectangular mounting plate 11 is adsorbed onto the surface of the housing plate 18 by means of the rubber suction cups 13. At this time, the external threaded base 19 is aligned and inserted into the notched ring. At the center of ring 15, the external thread base 19 is initially welded and positioned through the notch of the notched ring 15. During welding, it is necessary to keep away from the surface of the notched ring 15 to avoid welding the notched ring 15 to the housing plate 18 as a whole. When performing the positioning welding operation, the notched ring 15 is screwed to rotate and adjust the position of the notch. After the initial welding and positioning is completed at multiple points, the rectangular mounting plate 11 is removed as a whole, which achieves the effect of quickly welding and positioning the external thread base 19. The notched ring 15 does not need to be attached to the surface of the housing plate 18, but only needs to be positioned where the external thread base 19 can fit.

[0032] The outer surface of the external threaded base 19 is threaded with a valve 21, and a set of reinforcing pads 22 are provided on the outer surface of the box plate 18. The six box plates 18 are combined to form a liquid circuit box. Reinforcing pads 22 are welded and installed at the corners of the liquid circuit box for reinforcement.

[0033] A horizontal plate 23 is provided on the outer surface of the housing plate 18. An internally threaded mounting seat 24 is fixedly connected to the outer surface of the horizontal plate 23. A Z-shaped rotating block 25 is rotatably connected inside the internally threaded mounting seat 24. A threaded rod 26 is threadedly connected inside the internally threaded mounting seat 24 and the Z-shaped rotating block 25. A U-shaped abutment plate 27 is rotatably connected inside the threaded rod 26. The U-shaped abutment plate 27 is slidably connected to the outer surface of the horizontal plate 23. During the welding operation of the housing plate 18 and the reinforcing pad 22, the U-shaped abutment plate 27 is pushed to slide by turning the threaded rod 26. The two U-shaped abutment plates 27 slide and abut against the two ends of the reinforcing pad 22. The fixed pad 22 and the U-shaped abutment plate 27 have a groove at one end near the horizontal plate 23. The horizontal plate 23 is equipped with a slide rail to limit the sliding trajectory of the U-shaped abutment plate 27. When the threaded rod 26 is turned to push the U-shaped abutment plate 27 to slide, if the U-shaped abutment plate 27 is too far away from the reinforcing pad 22, the Z-shaped rotating block 25 can be pulled to rotate. At this time, the threaded rod 26 loses its upper limit and can be quickly pushed to slide so that it quickly approaches the reinforcing pad 22. The Z-shaped rotating block 25 is turned to reset, and the threaded rod 26 is restored to its limit in the Z-shaped rotating block 25 and the internal thread mounting seat 24.

[0034] To address the problems existing in the prior art, this utility model provides a welding component for a hydraulic tank. The center of the notched ring 15 is aligned with the center of the inlet / outlet openings on the tank plate 18. The external threaded base 19 is then inserted into the center of the notched ring 15. Using the notch in the notched ring 15, the external threaded base 19 is initially positioned for welding. After initial positioning, the notched ring 15 is screwed down, and its rotation adjusts the notch position. Multiple points are used for initial welding positioning of the external threaded base 19 at different locations. After completing multi-point positioning, the rectangular mounting plate 11 is removed as a whole. At this point, the external threaded base 19 and the tank plate 18 are stably fitted, completing the weld joint. This achieves rapid welding positioning of the external threaded base 19 on the tank plate 18. The entire process is smooth, avoiding the hassle of repeated adjustments or repositioning, reducing time wasted due to positioning operations, and enabling efficient and continuous welding work, thus accelerating the welding and installation process of the external threaded base 19 on the tank plate 18.

[0035] Rectangular mounting plate 11: As the basic load-bearing component of the entire positioning auxiliary structure, it provides an installation position for the fixing mechanism and the sleeve mechanism. Through the fixing mechanism, it adheres to the surface of the box plate 18 and provides a stable operating platform for the welding positioning of the external thread base 19.

[0036] Round rod 12: Makes the rubber suction cup 13 firmly installed on the rectangular mounting plate 11, and cooperates with the rubber suction cup 13 to connect the rectangular mounting plate 11 to the box plate 18, ensuring the adsorption stability of the rectangular mounting plate 11 on the surface of the box plate 18, and creating stable conditions for the welding positioning of the external thread base 19.

[0037] Rubber suction cup 13: Utilizing its own adsorption properties, when facing a smooth and rust-proof metal box plate 18 such as stainless steel or aluminum alloy, it can stably adsorb the rectangular mounting plate 11 onto the surface of the box plate 18, providing a stable support base for the welding positioning of the external thread base 19. During welding, be careful to keep away from the rubber suction cup 13 to avoid high temperature affecting its integrity. Adjust the position of the notched ring 15 to ensure that its adsorption function is not affected, so that the positioning structure can be reused.

[0038] T-shaped arc mounting block 14: enables the notched ring 15 to rotate relative to the rectangular mounting plate 11, providing the possibility of angle adjustment for multi-point welding positioning of the external thread base 19, and cooperating with the notched ring 15 to achieve preliminary welding positioning of the external thread base 19 at different positions, improving positioning accuracy and flexibility;

[0039] Notched ring 15: It is rotatably connected to the outer surface of the rectangular mounting plate 11 by cooperating with the T-shaped arc mounting block 14. Its center is aligned with the center of the inlet and outlet opening of the box plate 18, providing a center reference for the positioning of the external thread base 19. It uses its own notch to perform preliminary welding positioning of the external thread base 19. The notch position can be adjusted by turning and rotating to achieve multi-point preliminary welding positioning, ensuring that the external thread base 19 and the box plate 18 are stably attached and achieving rapid welding positioning.

[0040] Handle rod 16: It is fixedly connected to the outer surface of the rectangular mounting plate 11, which makes it convenient for the operator to hold and move the entire positioning structure, so as to accurately place the rectangular mounting plate 11 at the target position of the box plate 18. The position and angle can be flexibly adjusted during the positioning process, making the operation more convenient and efficient.

[0041] T-groove 17: Provides a track and support for the rotation of the notched ring 15 relative to the rectangular mounting plate 11, ensuring the stability and accuracy of the rotation of the notched ring 15, and ensuring the accuracy of the multi-point welding positioning of the external thread base 19;

[0042] Box plate 18: It is a component of the liquid circuit box. Six box plates 18 are combined to form the liquid circuit box. Its surface is used to install components such as external thread base 19 and reinforcing pad 22, providing a mounting base for the functional components of the liquid circuit box. Together with other box plates 18, it forms a space to contain liquid.

[0043] External threaded base 19: It works with valve 21 to realize the function of liquid inlet and outlet flow inside the liquid circuit tank. During installation, it is accurately positioned and welded to the tank plate 18 with the help of notched ring 15 to ensure a firm connection with the tank plate 18 and withstand the operating pressure of the liquid circuit system.

[0044] Valve 21: It serves to allow water to enter and exit, enabling the flow of liquid inside the liquid circuit tank. It is a key component for controlling the flow of liquid in the liquid circuit tank.

[0045] Reinforcing pad 22: Installed at the corner of the liquid circuit tank, it is fixedly connected to the tank plate 18 by welding to enhance the structural strength of the liquid circuit tank, improve the stability of the liquid circuit tank under liquid pressure, external vibration and other conditions, and extend its service life.

[0046] Horizontal plate 23: Fixed on the outer surface of the box plate 18, providing an installation position for the internal thread mounting seat 24. The slide rail mounted on its surface cooperates with the slide groove opened on the U-shaped abutment plate 27 to limit the sliding trajectory of the U-shaped abutment plate 27, so that the U-shaped abutment plate 27 slides in a straight line, ensuring accurate positioning of the reinforcing pad 22 when welding.

[0047] Internal thread mounting base 24: It is fixedly connected to the outer surface of the horizontal plate 23, internally rotatably connected to the Z-shaped rotating block 25, and threadedly connected to the threaded rod 26. It provides the mounting and movement base structure for the threaded rod 26 and the Z-shaped rotating block 25. Through the threaded engagement with the threaded rod 26, the rotational motion is converted into the linear motion of the threaded rod 26, which pushes the U-shaped abutment plate 27 to slide, thereby achieving tight fixing of the reinforcing pad 22 and ensuring the accurate position of the reinforcing pad 22 during welding.

[0048] Z-shaped rotating block 25: Rotatably connected inside the internal threaded mounting base 24, threadedly connected to the threaded rod 26, plays a key role in adjusting the position of the U-shaped contact plate 27. Normally, it works with the internal threaded mounting base 24 to limit the threaded rod 26, ensuring that the threaded rod 26 can rotate smoothly in a straight line. When the U-shaped contact plate 27 is too far from the reinforcing pad 22, the Z-shaped rotating block 25 is pulled to rotate, causing the threaded rod 26 to lose its upper limit, which makes it easier to quickly push the threaded rod 26 to slide, allowing the U-shaped contact plate 27 to quickly approach the reinforcing pad 22. After that, the Z-shaped rotating block 25 is rotated to reset, restoring the limit on the threaded rod 26, so as to accurately adjust the position of the U-shaped contact plate 27.

[0049] Threaded rod 26: By turning, the threaded transmission pushes the U-shaped contact plate 27 to slide along the slide rail on the surface of the horizontal plate 23, pressing against the reinforcing pad 22. It plays a positioning and fixing role when welding the reinforcing pad 22. With the cooperation of the Z-shaped rotating block 25, the distance between the U-shaped contact plate 27 and the reinforcing pad 22 can be flexibly adjusted to meet different positioning requirements.

[0050] U-shaped contact plate 27: Pushed by threaded rod 26, it slides and abuts against the reinforcing pads 22 at both ends. When welding box plate 18 and reinforcing pad 22, it limits the reinforcing pad 22, ensuring accurate welding position and enhancing welding effect. A groove is opened at one end near the horizontal plate 23 to cooperate with the slide rail on the surface of the horizontal plate 23, ensuring the linearity and stability of the sliding. Similar to notched ring 15, it positions and restricts the welding parts during welding. After the initial welding positioning, it is removed. At this time, the reinforcing pad 22 has completed the positioning, and the device can be reused.

[0051] Working principle:

[0052] The first step involves assembling six tank plates 18 to form a liquid circuit tank. To enhance the structural strength of the liquid circuit tank, reinforcing pads 22 are welded and installed at the corners. Two external threaded bases 19 are welded into the tank for threaded installation of valves 21. The two valves 21 respectively serve as inlet and outlet water, thus enabling flow within the liquid circuit tank. During the welding of the tank plates 18 and reinforcing pads 22, an adjustment structure consisting of a horizontal plate 23, an internal threaded mounting base 24, a Z-shaped rotating block 25, a threaded rod 26, and a U-shaped contact plate 27 is used. For auxiliary fixing, the horizontal plate 23 is fixed to the outer surface of the box plate 18, the internal thread mounting seat 24 is fixed to the outer surface of the horizontal plate 23, the Z-shaped rotating block 25 is rotatably connected to the inside of the internal thread mounting seat 24, the threaded rod 26 is threadedly connected to both the internal thread mounting seat 24 and the Z-shaped rotating block 25, and the U-shaped abutment plate 27 is rotatably connected to the inside of the threaded rod 26 and slidably connected to the outer surface of the horizontal plate 23. By turning the threaded rod 26, the threaded transmission pushes the U-shaped abutment plate 27 to slide along the slide rail on the surface of the horizontal plate 23, so that the two U-shaped abutment plates 27 slide and abut against the two... The reinforcing pad 22 at the end serves as a limiter during welding, ensuring accurate welding position and enhancing welding effect. If the U-shaped abutment plate 27 is too far from the reinforcing pad 22 while the threaded rod 26 is being turned to push it, the Z-shaped rotating block 25 can be pulled to rotate, causing the threaded rod 26 to lose its upper limit. At this point, the threaded rod 26 can be quickly pushed to slide, allowing the U-shaped abutment plate 27 to quickly approach the reinforcing pad 22. Once the U-shaped abutment plate 27 is close to the reinforcing pad 22 at the appropriate position, the Z-shaped rotating block 25 can be turned to reset. The threaded rod 26 is re-threaded into the Z-shaped rotating block 25 and the internal thread mounting seat 24, restoring the limit on the threaded rod 26. This allows for continued precise adjustment of the position of the U-shaped abutment plate 27 by screwing the threaded rod 26, ensuring the stable fixation of the reinforcing pad 22 during the welding process. Both the U-shaped abutment plate 27 and the notched ring 15 are used to position and restrict the welding components during welding. Although they may cause some obstruction during the welding operation, they can be removed after the initial welding positioning. At this point, all components have been positioned, and the device can be reused.

[0053] The second step, before welding the external threaded base 19 installed on the surface of the housing plate 18, involves first attaching the rectangular mounting plate 11 to the surface of the housing plate 18 using a fixing mechanism. Specifically, this is achieved using two round rods 12 and two rubber suction cups 13 in the fixing mechanism. (The rubber suction cups 13 can stably adhere to the surface of smooth metal materials such as stainless steel and aluminum alloy, which have good rust-resistant properties. The welding position should be far away from the rubber suction cups 13. For example, welding positioning can be performed at the notch of the notched ring 15.) Located at a 90-degree angle to the rubber suction cup 13, after welding at this point, it is rotated half a turn. At this time, it remains at a 90-degree angle to the rubber suction cup 13, away from it, to avoid affecting the integrity of the rubber suction cup 13 due to welding temperature. Welding is only for positioning; prolonged welding is not permitted, otherwise the surface temperature of the housing plate 18 will still affect the rubber suction cup 13. The rubber suction cup 13 is threaded onto the outer surface of the round rod 12. In this way, the rectangular mounting plate 11 is adhered and adsorbed onto the surface of the housing plate 18, providing a stable foundation for subsequent positioning. The notched ring... Align the center of ring 15 with the center of the inlet / outlet opening of the housing plate 18, and then align the external thread base 19 with the center of the notched ring 15. The notched ring 15 is rotatably connected to two T-shaped arc-shaped mounting blocks 14 on the outer surface of the rectangular mounting plate 11 through a sleeve mechanism. The T-shaped groove 17 inside the notched ring 15 cooperates with the T-shaped arc-shaped mounting blocks 14, allowing the notched ring 15 to rotate relative to the rectangular mounting plate 11. Use the notch of the notched ring 15 to perform preliminary welding and positioning of the external thread base 19. During welding, care should be taken to keep it away from the surface of the notched ring 15 to prevent it from... The external thread base 19 is welded together with the housing plate 18. After initial positioning, the notched ring 15 is screwed on and the position of the notch is adjusted by rotating it. The external thread base 19 is initially welded and positioned at multiple points in different positions. After the multi-point positioning is completed, the rectangular mounting plate 11 is removed as a whole. At this time, the external thread base 19 and the housing plate 18 are stably attached, and the weld can be completed. This achieves rapid welding and positioning of the external thread base 19 on the housing plate 18. The notched ring 15 only needs to provide enough position for the external thread base 19 to fit, and does not need to be attached to the surface of the housing plate 18.

[0054] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
