Description

Technical Field

[0001] This invention relates to the field of pump and valve casting welding technology, and in particular to a welding device for easily adjustable and positioned metal pump and valve castings. Background Technology

[0002] Metal pump and valve castings are widely used in industrial production, especially in fluid control systems where they play a crucial role. When welding metal pump and valve castings, they typically need to be fixed on a welding worktable to allow for precise welding operations by the welding equipment.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0022] refer to Figure 1-10 This invention provides an easily adjustable and positioned metal pump valve casting welding device, which mainly includes a base 1, a casting adsorption component 2, an air cooling component 3, and a monitoring component.

[0023] The base 1 primarily serves as a mounting and support structure, providing a carrier for the corresponding components. The casting adsorption assembly 2 is mainly used to fix the casting, facilitating subsequent welding operations. The air-cooling assembly 3 is mainly used to dissipate heat from the casting, reducing thermal deformation during welding. The monitoring assembly is mainly used to monitor the position and status of the casting adsorption assembly 2 and the casting, as well as to collect the casting's contour information.

[0024] Specifically, such as Figure 1 and Figure 6 As shown, the bottom of the base 1 is fixedly connected to multiple support legs 11, which are used to support the entire device on the ground to ensure that the device is placed stably. The base 1 has multiple through holes 12, which are used in conjunction with the air-cooling component 3 to achieve air-cooling and cooling of the welding area.

[0025] It should be noted that the base 1 has reserved installation areas on both sides. The installation areas are used to install parts for welding, such as gantry frames, modules and welding equipment. These parts, equipment and corresponding installation methods are all existing technologies and are not shown in detail in this embodiment.

[0026] In addition, such as Figure 1-5 and Figure 7-8 As shown, the casting adsorption assembly 2 is mounted on the base 1 and is used to adsorb and fix the metal pump valve casting.

[0027] The casting adsorption assembly 2 includes multiple adsorption modules 21, multiple sets of angle adjustment components 23, and multiple connecting plates 22. Each adsorption module 21 includes a support plate 211 and multiple adsorption components 212 disposed on the support plate 211.

[0028] The support plate 211 has multiple mounting holes 2111 spaced apart along its length. In the initial state, the axis of the mounting holes 2111 is vertical. The mounting holes 2111 mainly serve the purpose of installation, with multiple adsorption components 212 corresponding one-to-one with the multiple mounting holes 2111, and the adsorption components 212 are fixedly installed in the corresponding mounting holes 2111.

[0029] It should be noted that the support plate 211 is a long strip-shaped plate structure. The mounting holes 2111 are evenly distributed on the support plate 211, and the spacing between adjacent mounting holes 2111 can be designed according to the size of the casting and the adsorption requirements.

[0030] In addition, such as Figure 5 and Figure 8 As shown, the adsorption component 212 can be an annular electromagnet, and an annular stepped portion 2112 is provided inside the mounting hole 2111. The stepped portion 2112 is an annular protrusion structure inside the mounting hole 2111, used to support and position the electromagnet, and the electromagnet is fixedly connected to the top of the stepped portion 2112 by bolts.

[0031] Furthermore, the electromagnet is concentrically positioned on the step portion 2112, and the inner diameter of the electromagnet is greater than or equal to the inner diameter of the step portion 2112. This structural design allows the step portion 2112 to support the electromagnet, making its installation more secure and stable.

[0032] The top of the electromagnet is flush with the top of the corresponding support plate 211, making the working surface of the electromagnet level with the upper surface of the support plate 211. This shortens the distance between the electromagnet and the casting, reduces hard contact between them, and helps protect the surfaces of both the electromagnet and the casting. The electromagnet is connected to a control power supply via wires, enabling it to be magnetized when energized and demagnetized when de-energized, facilitating the installation and removal of the casting.

[0033] In addition, such as Figure 3 As shown, the connecting plate 22 is disposed between two adjacent support plates 211, and multiple connecting plates 22 are used to connect multiple support plates 211 into a whole.

[0034] In this embodiment, two connecting plates 22 are configured between two adjacent support plates 211, and the two connecting plates 22 are respectively disposed at both ends of the corresponding support plate 211. The two ends of the connecting plates 22 are rotatably connected to the end faces of the corresponding two adjacent support plates 211. This rotatable connection method allows the support plates 211 to have a certain amount of room for movement when adjusting the angle, while maintaining overall stability.

[0035] The connecting plate 22 serves as the connecting hub for multiple support plates 211. It is arranged between adjacent support plates 211, integrating the dispersed support plates 211 into a coordinated and interconnected adsorption unit. This ensures the integrity of the structure without restricting the attitude adjustment of individual support plates 211.

[0036] The above design not only provides sufficient space for the angle and height adjustment of the support plate 211 to avoid jamming and deformation caused by rigid connection, but also prevents excessive offset of a single support plate 211 through the linkage constraint at both ends, so as to always maintain the continuity and stability of the overall adsorption surface and adapt to the fitting requirements of complex curved surface castings.

[0037] In addition, such as Figure 2 As shown, multiple sets of angle adjustment components 23 correspond one-to-one with multiple support plates 211, and are used to adjust the height and tilt angle of the corresponding support plate 211. Each set of angle adjustment components 23 includes at least two angle adjustment components 23. By activating the angle adjustment components 23 at different positions, the height and tilt angle of the corresponding support plate 211 can be adjusted to adapt to the lower surface contour of the casting.

[0038] Specifically, such as Figure 3 and Figure 9 As shown, the angle adjustment assembly 23 includes a cylinder 231, a Hooke hinge 232, and a second Hooke hinge 233. Cylinder 231 is the driving component, capable of generating push-pull force to drive the support plate 211 to rise, fall, and adjust its angle. The cylinder body of cylinder 231 is fixedly connected to the base 1 via the first Hooke hinge 232, which allows for rotational connection at any angle, providing flexibility in the installation angle of cylinder 231. The telescopic end of cylinder 231 is fixedly connected to the bottom of the support plate 211 via the second Hooke hinge 233, which also allows for rotational connection at any angle, enabling the telescopic direction of cylinder 231 to adapt to the adjustable posture of the support plate 211.

[0039] Each set of angle adjustment components 23 includes at least two angle adjustment components 23. In this embodiment, each set of angle adjustment components 23 includes two angle adjustment components 23. The two cylinders 231 are respectively arranged at different positions on the support plate 211, for example, at both ends of the support plate 211.

[0040] In use, when the height of the support plate 211 needs to be adjusted, the extension and retraction of the two cylinders 231 can be controlled simultaneously to make the support plate 211 rise and fall as a whole. Since the two adjacent support plates 211 are connected by the connecting plate 22, and the cylinder 231 is connected to the bottom of the corresponding support plate 211 by the Hooke hinge 233, the support plate 211 will also rotate under the restraint of the adjacent support plate 211 and the connecting plate 22 while it is rising and falling. This allows the upper surface of the support plate 211 to fit more closely to the lower surface contour of the casting, thereby better adsorbing and fixing the casting.

[0041] As an optional embodiment, each set of angle adjustment components 23 includes multiple angle adjustment components 23, and the multiple angle adjustment components 23 are spaced apart along the length direction of the corresponding support plate 211. This can increase the support plate 211 with more support points, improve the load-bearing capacity of the support plate 211, and is suitable for use in heavy-duty pump and valve castings, thus improving the applicability of the device.

[0042] As an optional embodiment, the angle adjustment assembly 23 includes a servo electric push rod, a cross hinge seat one and a cross hinge seat two. The cylinder part of the electric push rod is fixedly connected to the base 1 through the cross hinge seat one, and the telescopic part of the electric push rod is fixedly connected to the bottom of the support plate 211 through the cross hinge seat two.

[0043] Electric linear actuators offer advantages such as higher control precision, stronger stroke controllability, no risk of pneumatic leakage, and lower noise; they are suitable for high-precision welding, cleanrooms, and quiet operating environments, and can be used for positioning precision pump and valve castings.

[0044] As an optional embodiment, the angle adjustment assembly 23 includes a hydraulic cylinder, a spherical hinge one, and a spherical hinge two. The cylinder body of the hydraulic cylinder is fixedly connected to the base 1 through the spherical hinge one, and the telescopic part of the hydraulic cylinder is fixedly connected to the bottom of the support plate 211 through the spherical hinge two.

[0045] Compared to pneumatic cylinders and electric actuators, hydraulic cylinders offer greater driving capacity and exceptional stability. Furthermore, the spherical hinge provides a wider adjustment range and more flexible steering, making them suitable for ultra-heavy-duty metal pump and valve castings and heavy-duty welding positioning applications.

[0046] As an optional embodiment, the connecting plate 22 can employ an elastic damping hinge. During adjustment, the elastic damping hinge can buffer and reduce vibration, minimizing the impact of the support plate 211 rapidly deflecting and striking the casting surface, thus protecting the casting surface. The elastic damping hinge can be a spring-damped hinge or other suitable hinges. Of course, other suitable connecting components can also be used for the connecting plate 22.

[0047] Furthermore, such as Figure 7As shown, a water-cooling channel 2113 is formed along the length of the support plate 211. The water-cooling channel 2113 is located at the edge of the support plate 211 to avoid the mounting hole 2111. Inlet and outlet pipes, respectively, are provided at both ends of the water-cooling channel 2113, communicating with the outside. Both the inlet and outlet pipes are located at the bottom of the corresponding support plate 211. Cooling water flows through the water-cooling channel 2113, which can cool the support plate 211 and the electromagnet during the welding process, preventing excessive temperature from affecting the magnetic properties of the electromagnet or causing heat deformation of the casting.

[0048] In addition, such as Figure 6 As shown, the air-cooling component 3 is installed inside or at the bottom of the base 1 and is used to cool the welding area with air.

[0049] The air-cooled assembly 3 includes multiple fans 31, each corresponding to a specific through hole 12. The fans 31 are fixedly installed within their respective through holes 12 to blow air onto the support plate 211. In this embodiment, the fans 31 are preferably centrifugal fans or axial fans, capable of generating sufficient airflow and pressure to blow air towards the support plate 211 and the welding area of ​​the casting, carrying away heat from the support plate 211. The air-cooled assembly 3, in conjunction with the water-cooled channel 2113, achieves a highly efficient dual cooling effect.

[0050] In addition, such as Figure 8 As shown, the monitoring component is mainly used to monitor the position and status of the casting adsorption component 2 and the casting, as well as to collect the contour information of the casting. The monitoring component includes multiple pressure sensors 4 and multiple cameras.

[0051] Pressure sensor 4 corresponds one-to-one with multiple electromagnets, and is fixedly connected to the top of the corresponding electromagnet to monitor the pressure between the electromagnet and the casting. When the electromagnet attracts the casting, pressure sensor 4 can detect the magnitude of the attraction force in real time and feed the signal back to the control system. The control system adjusts the magnetism of the electromagnet according to the feedback signal to maintain a stable attraction force. Pressure sensor 4 can be a miniature thin-film pressure sensor or a piezoresistive sensor, or other suitable pressure sensors.

[0052] The cameras are mounted on the base 1. Specifically, multiple cameras can be partially fixed to the base 1 via brackets and located below the support plate 211, while other parts can be fixed to the base 1 via brackets and located diagonally above the support plate 211. This allows for more comprehensive monitoring and information collection of the casting adsorption assembly 2 and the casting. The cameras can be industrial cameras or vision sensors, capable of capturing images of the lower surface of the casting. The control system uses image processing algorithms to identify the contour of the casting and automatically adjusts the angle adjustment assembly 23 based on the identification results, ensuring that the adsorption surface of the support plate 211 matches the contour of the casting. The image processing algorithm can employ existing technology.

[0053] In addition, as an optional embodiment, such as Figure 9 and Figure 10 As shown, the adsorption component 212 includes multiple vacuum suction cups 2121 and a lifting component 2122.

[0054] A vacuum suction cup 2121 is installed within the corresponding mounting hole 2111. That is, within the mounting hole 2111, the vacuum suction cup 2121 replaces the electromagnet, forming a sealed space with the surface of the casting. By drawing a vacuum, a negative pressure is created between the vacuum suction cup 2121 and the casting, achieving adsorption and fixation. In this way, the device can adapt to the adsorption needs of castings of different materials and in different locations.

[0055] Specifically, the lifting assembly 2122 is disposed at the bottom of the corresponding support plate 211 and is used to drive the vacuum suction cup 2121 to move axially along the mounting hole 2111. The lifting assembly 2122 includes a U-shaped frame 21221, a cylinder 21222, and a connecting frame 21223.

[0056] The U-shaped frame 21221 is fixedly connected to the bottom of the corresponding support plate 211, and its opening faces the corresponding support plate 211. The U-shaped frame 21221 includes two longitudinal beams and one transverse beam. The two longitudinal beams are arranged parallel to each other, and one end of the longitudinal beam is fixedly connected to the bottom of the corresponding support plate 211. The two ends of the transverse beam are fixedly connected to the other ends of the two longitudinal beams, respectively. The overall shape of the U-shaped frame 21221 is U-shaped, which can provide stable mounting support for cylinder 21222.

[0057] The cylinder body of cylinder 21222 is fixedly connected to the crossbeam, and the axis of the telescopic end of cylinder 21222 is collinear with the axis of the corresponding mounting hole 2111, ensuring that the telescopic movement direction of cylinder 21222 is consistent with the axial direction of the mounting hole 2111. The telescopic end of cylinder 21222 is fixedly connected to the corresponding vacuum suction cup 2121, and is used to drive the vacuum suction cup 2121 to perform lifting and lowering movements.

[0058] The connecting frame 21223 is used to connect the telescopic end of the cylinder 21222 and the vacuum suction cup 2121. The connecting frame 21223 includes a connecting ring 21224, a drive plate 21225 and multiple connecting posts 21226.

[0059] A connecting ring 21224 is concentrically fixed to the outside of the vacuum suction cup 2121 pipe. A drive plate 21225 is concentrically spaced from the connecting ring 21224, and one side of the drive plate 21225 is fixedly connected to the telescopic end of the cylinder 21222. Both ends of multiple connecting posts 21226 are fixedly connected to the connecting ring 21224 and the drive plate 21225, respectively. A clearance space is formed between the connecting posts 21226, the connecting ring 21224, and the drive plate 21225 to facilitate the connection of the external pipe to the vacuum suction cup 2121 pipe for vacuum extraction.

[0060] In use, initially, the vacuum suction cup 2121 is located inside the mounting hole 2111. When it is necessary to adsorb the casting, the cylinder 21222 drives the vacuum suction cup 2121 to rise, so that it contacts the lower surface of the casting. Then, the air inside the vacuum suction cup 2121 is extracted by an external vacuum pump to form a negative pressure, thereby achieving adsorption.

[0061] When it is necessary to remove the casting, first release the negative pressure in the vacuum suction cup 2121, and then the cylinder 21222 drives the vacuum suction cup 2121 to descend and separate from the casting.

[0062] The invention also includes a control system and multiple temperature sensors. These temperature sensors are fixedly installed at intervals on the bottom of the support plate 211 to collect the ambient temperature around the support plate 211. The control system is electrically connected to the pressure sensor 4, camera, cylinder 231, cylinder 21222, welding components and equipment, the external air pump of the vacuum suction cup 2121, fan 31, temperature sensors, and the external water pump corresponding to the water cooling channel 2113. The control system can receive and analyze information from the pressure sensor 4, camera, and temperature sensors, and control the cylinder 231, cylinder 21222, welding components and equipment, the external air pump of the vacuum suction cup 2121, fan 31, and the external water pump corresponding to the water cooling channel 2113 to perform corresponding operations.

[0063] Working principle: Step 1: Place the metal pump valve casting to be welded in the middle position above the support plate 211 of the casting adsorption assembly 2.

[0064] Step 2: Activate the camera to collect the contour information of the lower surface of the casting and transmit the information to the control system.

[0065] Step 3: Based on the collected contour information, the control system calculates the angle and height that the support plate 211 needs to be adjusted, and then controls the cylinder 231 in each angle adjustment component 23 to extend and retract accordingly, adjusting the tilt angle and height of the support plate 211 so that the upper surface of the support plate 211 fits the contour of the lower surface of the casting.

[0066] Step four: The electromagnet is energized and magnetized, generating a magnetic force to attract the ferromagnetic parts of the casting. Simultaneously, pressure sensor 4 monitors the adsorption pressure in real time, and the control system adjusts the electromagnet's magnetism based on the monitoring results to ensure stable adsorption force.

[0067] Step 5: During the welding process, activate the air-cooling component 3 and the water-cooling channel 2113 as needed to cool the welding area and prevent overheating.

[0068] Step six: After completing the above positioning steps, welding can be performed on the casting.

[0069] Step 7: After welding is completed, first turn off the power to the electromagnet to demagnetize and release the casting; for the vacuum adsorption part, release the negative pressure in the vacuum chuck 2121, and then the cylinder 21222 drives the vacuum chuck 2121 to descend and remove the casting.

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.
