Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding or cutting equipment or process, in particular to a filter ring seam welding device. BACKGROUND

[0002] In the existing filter processing and manufacturing process, the welding link is one of the most important processes. Especially between the end cover and the shell of the filter, or between the filter body and the support frame, ring seam welding is often needed to ensure its sealing and firmness. However, the filter welding device widely used at present is mostly based on the principle of fixed-point welding or local welding, that is, through the electrode or welding head at the fixed position, the workpiece is spot welded, and then the workpiece is rotated by the worker or the simple rotating mechanism, so as to complete the overall welding in the circumferential direction. This method has obvious shortcomings: on the one hand, the fixed-point welding is difficult to guarantee the precision and consistency, and the ring seam is easy to appear virtual welding or uneven welding, which directly affects the sealing effect and service life of the filter; on the other hand, the rotation of the workpiece depends on the simple mechanical structure, and the positioning is not accurate enough, especially when the size of the filter is diversified, it takes a lot of time and effort to replace and debug the device, which is difficult to meet the batch production needs of different specifications of products. In addition, such device has single function, and can only realize ring seam welding in a single direction, lacks pre-processing ability, and cannot meet the welding requirements when the surface state of the filter is different.

[0003] More prominent problem is that the existing filter ring seam welding device generally lacks the function of pre-welding treatment of the workpiece. In actual production, the filter may be attached with oxide skin, rust, water vapor or oil stains due to transportation, storage or preliminary processing, and these impurities are easy to cause porosity, slag inclusion or insufficient welding strength in the welding process if not removed in advance, which seriously reduces the product quality. However, the existing equipment directly places the filter on the welding fixture, lacks the cooperation of pre-processes such as rust removal, drying and cleaning, and thus it is necessary to set up independent processes in the production process, which not only increases the labor and equipment cost, but also reduces the production efficiency. At the same time, the welding position of the existing device is mostly fixed at the top of the device, and the welding posture is single, which is not conducive to adjusting the welding angle and welding position according to different product structures, resulting in narrow application range of the device. Especially in the background of various types of filters and complex structures, such fixed-position welding device is difficult to meet the actual needs of various situations, and there is an urgent need for an improved filter ring seam welding device that can consider pre-welding treatment, welding flexibility and welding quality.

DETAILED DESCRIPTION

[0032] In order to make the above objectives, features and advantages of the present application more apparent and comprehensible, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0033] As Figures 1-10As shown, a filter core ring seam welding device includes a base 1, a drive box 2, a rotating jaw 3, a fixed rotating shaft 4, an adjusting assembly 5, a moving platform 6, an installation platform 7, and a welding mechanism 8. The device takes the base 1 as the main frame, which is installed on the ground to provide stable support for the entire device and avoid affecting the welding precision due to vibration or deviation during the welding process. The drive box 2 is installed above the base 1 and has a driving component inside to provide power support for rotating and welding actions. The output end of the drive box 2 is installed with the rotating jaw 3, which is used to clamp and drive the filter core workpiece to rotate, thereby ensuring that the workpiece can achieve continuous and uniform ring seam welding during welding. In order to improve the stability and adaptability of the device, the fixed rotating shaft 4 is also installed above the base 1, which can limit the position of the workpiece to keep it balanced during rotation and avoid shaking or deviation.

[0034] In terms of the design of the adjusting mechanism, the device is provided with three adjusting assemblies 5, which are installed on the side of the fixed rotating shaft 4, the side of the moving platform 6, and the side of the installation platform 7. Through the cooperation of the three adjusting assemblies 5, the workpiece clamping angle, the welding mechanism 8 position, and the platform moving range can be flexibly adjusted to meet the welding needs of filter core workpieces of different sizes and structures. The moving platform 6 is installed above the base 1 and can slide along the horizontal track of the base 1, which facilitates the adjustment of the relative position between the workpiece and the welding head and helps to achieve precise weld positioning. The installation platform 7 is fixed above the moving platform 6 and serves as the bearing platform of the welding mechanism 8, providing a stable installation foundation for the welding process.

[0035] As shown in Figure 3 The welding mechanism 8 is installed above the installation platform 7 and has a rotating assembly 83 inside. The rotating assembly 83 can rotate under the drive of the driving gear 825 to flexibly adjust the position distribution of the welding work assembly 85. Through this design, the movement trajectory of the welding head on the ring seam can be effectively controlled, and the synchronous driving of the rotating jaw 3 is matched to keep the welding mechanism 8 at a stable welding angle and uniform heat input while the filter core workpiece is rotating. This not only ensures the continuity and strength of the weld, but also allows for adaptive adjustment of different specifications of the filter core, improving the versatility and flexibility of the device. Overall, the device can achieve efficient, stable, and highly adaptable ring seam welding of filter cores through the stable support of the base 1, the power output of the drive box 2, the workpiece rotation of the rotating jaw 3, the flexible adjustment of the adjusting assembly 5, and the precise control of the welding mechanism 8, significantly improving the problems of single function, fixed welding position, and insufficient adaptability of traditional equipment.

[0036] The welding mechanism 8 comprises a mounting base plate 81, a fixing assembly 82, a rotating assembly 83, a connecting assembly 84 and a working assembly 85. The mounting base plate 81 serves as the load-bearing structure of the entire welding mechanism 8 and is firmly mounted above the mounting platform 7 and stably constrained by the double-sided clamping fixation of the mounting platform 7. This structure can effectively avoid the problem of uneven welds caused by vibration or deviation during welding, ensuring welding precision and reliability. The fixing assembly 82 is arranged above the mounting base plate 81 and provides installation space and support for the rotating assembly 83. The rotating assembly 83 is installed inside the fixing assembly 82 and can achieve smooth rotational motion inside the fixing assembly 82, thereby driving the connecting assembly 84 and the working assembly 85 below to adjust the angle. Through the design of the rotating assembly 83, the working assembly 85 can flexibly change the welding angle and welding path, so that the device can not only complete single-position welding, but also perform ring seam or local multi-angle welding operations according to the structure of the workpiece.

[0037] Further, the connecting assembly 84 is installed on the inner side of the rotating assembly 83. The connecting assembly 84 provides installation interfaces for different working assemblies 85, enabling the entire device to have good compatibility and expandability. By replacing different working assemblies 85, the welding mechanism 8 can adapt to various production process requirements. The working assembly 85 is installed inside the connecting assembly 84. Typically, the working assembly 85 is mainly configured as a welding component to complete the ring seam welding of the filter element. According to actual process requirements, the working assembly 85 can also be replaced by a rust remover spray head, a high-pressure spray head or a hot air spray head to achieve rust removal, impurity blowing and pre-welding drying of the filter element surface, respectively. This multifunctional design greatly improves the application range of the welding mechanism 8, enabling the device not only to complete high-quality welding, but also to undertake key steps in pre-welding processing, thereby improving the continuity and production efficiency of the overall process.

[0038] As Figure 5As shown, the fixed assembly 82 is integrally arranged in a circular ring structure, which mainly includes a fixed ring 821, a limiting groove 822, a rotating groove 823, a mounting groove 824, a drive gear 825, and an extension electric pole 826, etc. The fixed ring 821, as the main part of the fixed assembly 82, is firmly mounted above the mounting bottom plate 81 by welding, so as to ensure sufficient stability and bearing capacity during work, and will not be loose due to external force or mechanical vibration. The fixed ring 821 plays a role of core frame in the overall structure, and the limiting groove 822 and the mounting groove 824 are formed in the inside, and the rotating groove 823 is formed in the inner side. The limiting groove 822 and the rotating groove 823 are arranged in a ring structure, and the ring design facilitates the containment and limitation of the rotating assembly 83, so that the rotating assembly 83 can rotate stably under the constraint of the fixed ring 821 and will not deviate or fall off. At the same time, the limiting groove 822 is not only used to limit the movement track of the rotating assembly 83, but also can further position and fix the rotating assembly 83 under the cooperation of the extension electric pole 826, so as to improve the accuracy of the overall operation.

[0039] The mounting groove 824 is also formed in the inside of the fixed ring 821, and the mounting groove 824 and the limiting groove 822 are in communication, providing a mounting space for the arrangement of the drive gear 825. The drive gear 825 is installed in the inside of the mounting groove 824, and the position is close to one side of the limiting groove 822, so as to directly mesh with the rotating teeth 832 arranged on the rotating ring 831. Through this gear transmission mode, when the micro motor in the inside of the fixed ring 821 starts, it can drive the drive gear 825 to rotate, and then drive the rotating ring 831, so that the rotating assembly 83 rotates stably according to the preset track, so as to realize the angle adjustment of the working assembly 85 and the continuity of the girth seam welding. The design structure is compact, the transmission efficiency is high, and the energy loss can be effectively reduced and the synchronization of rotation can be ensured.

[0040] In addition, the fixed assembly 82 is also provided with the extension electric pole 826, which can perform extension and retraction movement in the limiting groove 822, and one end of the extension electric pole 826 is connected with a micro air cylinder. Through the driving action of the micro air cylinder, the extension and retraction adjustment of the electric pole can be realized. The extension electric pole 826 can not only provide auxiliary support for the rotating assembly 83 during operation, but also can lock and release the rotating assembly 83 when necessary, so as to improve the flexibility and safety of the device under different working conditions. Overall, the fixed assembly 82 realizes the stable driving and multi-angle adjustment function of the rotating assembly 83 through the stable support of the fixed ring 821, the accurate constraint of the limiting groove 822 and the rotating groove 823, the efficient transmission of the drive gear 825, and the auxiliary positioning of the extension electric pole 826, which provides a solid guarantee for the reliable operation of the welding mechanism 8.

[0041] The limiting groove 822 and the rotating groove 823 are in communication with each other, and the cross-sectional shape formed by the combination of the two is designed as a "convex" structure. The geometric feature of the "convex" shape can provide multi-directional limiting support during the rotation of the rotating assembly 83, so that the rotating assembly 83 always operates within the predetermined track and does not shake or deviate due to inertia or external disturbance. This not only ensures the continuity and stability of the weld during welding, but also enables the rust removal, cleaning, drying and other preparation work before welding to be smoothly completed, further improving the integrity and reliability of the overall process.

[0042] In terms of fixation, the cross-sectional shape of the telescopic electric pole 826 is designed as a cross shape. Compared with ordinary circular or rectangular cross sections, the cross-shaped cross section is easier to achieve precise clamping and alignment with the control hole 833 and the cross-shaped groove 834, thereby effectively improving the firmness of the fixation. The telescopic electric poles 826 are distributed in a circumferential array inside the fixing ring 821, and by simultaneously acting on the rotating assembly 83 through multiple telescopic electric poles 826, uniform support and constraint in different directions of the rotating assembly 83 can be provided, avoiding eccentric rotation phenomenon. This design not only significantly improves the stability of the rotating assembly 83 during operation, but also plays a key role in improving the uniformity of the weld and the welding quality, providing structural support for the realization of high-precision and high-reliability ring seam welding of the whole machine.

[0043] As shown in Figures 6-8 The rotating assembly 83 mainly consists of a rotating ring 831, rotating teeth 832, a control hole 833 and a cross-shaped groove 834. The rotating ring 831 is installed inside the fixing assembly 82 and is the main part of the rotating assembly 83. Its main function is to rotate smoothly under the drive of the drive gear 825, thereby moving different types of working assemblies 85 one by one to the appropriate working position. In this way, the device can flexibly switch different functional modules, such as welding parts, rust removal nozzles or drying nozzles, on the same platform to meet the continuous processing needs of different processes. In order to realize reliable transmission, the outer surface of the rotating ring 831 is uniformly provided with rotating teeth 832, and the rotating teeth 832 form a meshing relationship with the drive gear 825. When the drive gear 825 rotates, it can effectively drive the rotating ring 831 to rotate and ensure the stability and synchronization of its rotation, thereby avoiding the phenomenon of slipping or uneven rotation.

[0044] In terms of positioning and fixing, a plurality of control holes 833 are formed on the outer surface of the rotating ring 831, and a cross-shaped groove 834 is further arranged on the inner side of each control hole 833. This design enables the control hole 833 and the cross-shaped groove 834 to be used together with the telescopic electric pole 826. When the rotating ring 831 completes a rotation of a predetermined angle and rotates the target work assembly 85 to a specified working position, the telescopic electric pole 826 can be extended under the control instruction and clamped into the control hole 833 and the cross-shaped groove 834. Due to the special geometric shape of the cross-shaped groove 834, a multi-directional limiting effect can be provided, so that the telescopic electric pole 826 can form a firm locking effect on the rotating ring 831 after clamping, preventing displacement due to vibration or stress during welding or pre-welding treatment. This structure not only effectively ensures the stability of the welding process, but also improves the uniformity of the welding seam and the reliability of the process. Overall, the rotating assembly 83 realizes the quick switching and stable fixing of the work assembly 85 between different workstations through the design of "driving rotation + precise positioning + reliable locking", which provides important support for the multifunctionalization and high-precision welding of the device.

[0045] As shown in Figure 9 , the rotating assembly 83 further includes mounting holes 835, cooling channels 836, and conductive columns 837, and other additional structures for further enhancing the versatility and working stability of the rotating assembly 83. Specifically, the mounting holes 835 are formed on the inner side of the rotating ring 831, and the mounting holes 835 provide a reliable mounting position for the connecting assembly 84, so that the connecting assembly 84 can be stably embedded therein, thereby facilitating the replacement and installation of different work assemblies 85. Through this structural arrangement, the versatility and expandability of the rotating assembly 83 during assembly can be effectively improved, meeting the needs of various welding and pre-welding treatment processes.

[0046] In order to avoid performance degradation of the rotating assembly 83 due to temperature rise in a long-time working state, a cooling channel 836 is arranged inside the rotating assembly 83. The cooling channel 836 is arranged in a circular ring shape, and can be filled with water or other high-thermal-conductivity liquids, such as cooling oil, liquid metal coolant, etc. These high-thermal-conductivity liquids can quickly absorb and conduct the heat generated during operation of the rotating assembly 83, thereby achieving cooling treatment of the entire rotating assembly 83. Through the cooling cycle of the cooling channel 836, the stability of the temperature of the rotating assembly 83 can be effectively guaranteed, avoiding damage to electronic components or precision decline due to overheating, thereby ensuring that the internal electrical parts are in a long-term high-efficiency running state, greatly improving the durability and continuous working ability of the device.

[0047] In addition, the rotating assembly 83 is also designed with a conductive column 837 inside, which is installed in the mounting hole 835 and coated with an insulating waterproof layer outside, so as to ensure the transmission of electric energy while avoiding safety hazards such as short circuit or electric leakage. The two ends of the conductive column 837 are communicated with the mounting hole 835 and the control hole 833 respectively, and through this arrangement, the electrical connection between the working assembly 85 and the fixed assembly 82 can be realized. Since the working assembly 85 needs to rotate with the rotating ring 831 during use, if the traditional power supply line mode is adopted, it is easy to affect the service life due to cable twisting, winding or excessive bending, and even cause power interruption. The present scheme innovatively pre-buries the power supply line in the interior of the fixed assembly 82, and at the same time, a wire is arranged in the middle of the telescopic pole 826, and the extension and docking of the conductive path are completed through the conductive column 837. In this way, when the telescopic pole 826 cooperates with the connecting assembly 84 and the working assembly 85, the electric energy can be transmitted to the working assembly 85 in time and stably, realizing the continuous power supply of the welding parts or the spray head parts.

[0048] In summary, the rotating assembly 83 realizes efficient docking with the connecting assembly 84 through the mounting hole 835, realizes accurate control of the overall temperature through the cooling flow channel 836, and solves the problem of rotating power supply through the conductive column 837 combined with the internal wiring mode. This design not only ensures the long-term stable operation of the rotating assembly 83 under complex working conditions, but also enables the working assembly 85 to maintain a reliable working state in a high-intensity continuous operation environment, thereby significantly improving the welding quality and the service life of the whole device.

[0049] As shown in Figure 10 The connecting assembly 84 mainly includes a connecting sleeve 841, a mounting clamping block 842 and a conductive block 843. The connecting sleeve 841 is installed inside the rotating assembly 83 and serves as the main structure for bearing and positioning, which can provide a stable mounting basis for different working assemblies 85. The mounting clamping block 842 is arranged on the inner side surface of the connecting sleeve 841 and is used to limit and clamp the inserted working assembly 85, so that it does not shake or fall off during work, ensuring the stability of welding and pretreatment operation. The conductive block 843 is installed at the bottom of the connecting sleeve 841 and realizes reliable electrical connection with the conductive column 837, so as to smoothly transmit electric energy to the interior of the working assembly 85 and provide continuous and stable power support for the welding parts or other functional spray heads.

[0050] The installation clamping block 842 is arranged in an arched structure, and the arched design can achieve a more tightly and stably clamped effect when cooperating with the clamping groove 854, thereby effectively avoiding loosening caused by vibration or stress during work, and further improving the overall stability and reliability of the working assembly 85. The installation clamping block 842 is evenly distributed on the inner side of the connecting sleeve 841 in a ring array manner. This arrangement not only ensures that each clamping block is evenly stressed and prolongs the service life, but also provides more convenient operation space when disassembling or installing. The upper surface of the conductive block 843 is covered with a conductive coating, which can reduce the contact resistance and enhance the conductivity, thereby ensuring stable transmission of current. The conductive coating is reliably electrically connected with the shell column 851, so that the electric energy can be efficiently transmitted to the working assembly 85, thereby providing continuous and stable power supply support for it, and ensuring that the entire device can maintain an efficient and safe working state during operation.

[0051] The working assembly 85 includes three parts of the shell column 851, the working head 852 and the clamping nut 853. The shell column 851 is the main part of the working assembly 85, which has good strength and stability as a whole, and can provide reliable support for each component during operation. The lower part of the shell column 851 is designed as a power supply part, and the bottom surface is made of a high-conductivity conductor material, so that stable transmission of electric energy is achieved when in contact with the conductive block 843, and the working head 852 can continuously obtain the required electric energy. The working head 852 is installed at one end of the shell column 851 and can be replaced flexibly according to different process requirements. For example, when it is arranged as a welding head, it can realize efficient welding of the filter ring seam; when it is arranged as a water jet head, it can clean or rust the workpiece; and when it is arranged as a high-pressure air gun head, it can quickly complete the drying operation of the workpiece surface, realizing multi-functional process support. The clamping nut 853 is installed on the outer side of the shell column 851, and its main function is to limit and fix the working assembly 85, so as to avoid deviation or loosening during work, and ensure that the entire device can maintain a stable, safe and efficient operating state.

[0052] The working assembly 85 further comprises a clamping groove 854 and a through groove 855, which are matched with each other to realize quick installation and stable fixation of the working assembly 85. Specifically, the clamping groove 854 is arranged on the outer surface of the shell column 851 and is designed as an annular groove structure, which can provide a precise limiting position for the installation clamping block 842, so as to ensure that the shell column 851 does not deviate during the working process. The through groove 855 is arranged below the clamping groove 854 and extends along the axial direction of the shell column 851 to the bottom surface thereof. During installation, the installation clamping block 842 can be smoothly inserted through the through groove 855, then enter the inside of the clamping groove 854, and then be tightly clamped and fixed according to the geometric shapes of the two. This design not only improves the installation and disassembly efficiency of the working assembly 85, but also greatly improves the reliability of the connection. At the same time, after the shell column 851 is fixed in the clamping groove 854, the bottom surface thereof is in close contact with the upper surface of the conductive block 843, thereby completing the electrical connection, so that the electrical energy can be efficiently transmitted to the inside of the working assembly 85, and the stable operation of the working assembly 85 under different working conditions is ensured.

[0053] During the working process of the present application, the working process of the filter core ring seam welding device mainly includes workpiece installation, work position adjustment, welding and pre-welding treatment, and the rotating assembly 83 drives the working assembly 85 to complete the ring seam welding. First, the filter core workpiece to be welded is placed in the rotating clamp jaw 3, and the workpiece is clamped and fixed by the rotating clamp jaw 3, and the rotating shaft 4 is fixed to provide additional positioning support, so as to ensure that the workpiece remains stable during rotation. The moving platform 6 can be adjusted in the transverse sliding direction by the adjusting assembly 5 according to the size of the workpiece, and the installation platform 7 carries the welding mechanism 8 and is positioned with high precision, so that the relative position between the welding mechanism 8 and the workpiece reaches the best state.

[0054] In the welding or pretreatment process, the worker first determines the adaptive scheme according to the condition of the filter element, sets the working head 852 of the working assembly 85 to the corresponding rust remover spray head, high-temperature air gun head and welding head, starts the rust remover spray head and high-temperature air gun head to process the filter element joint, and then starts the welding head to weld. Before welding, the position of the welding point needs to be determined. First, the telescopic electric pole 826 is started to be separated from the control hole 833 and the cross slot 834, and the drive gear 825 is started to drive the rotating ring 831 to rotate, so that the working assembly 85 moves continuously in the circumferential direction. After the working assembly 85 is positioned at the specified position, the power supply of the drive gear 825 is suspended, the telescopic electric pole 826 is extended and clamped into the control hole 833 and the cross slot 834, and the circuit connection of the "telescopic electric pole 826-conductive column 837-conductive block 843-outer shell column 851-working head 852" is realized, so that the working assembly 85 is powered. The welding or spraying process can be stably carried out. The cooling flow channel 836 inside the rotating assembly 83 circulates high-thermal-conductivity liquid to ensure the temperature stability of the rotating assembly 83 and avoid overheating of electronic components. After rotation, the telescopic electric pole 826 is clamped into the control hole 833 and the cross slot 834 to lock and fix the working assembly 85, further improving the welding precision; during welding, the rotating claw 3 and the fixed rotating shaft 4 drive the filter element workpiece to rotate synchronously, so that the girth seam is welded.

[0055] The working principle of the present application is based on the cooperative movement of the rotating assembly 83 and the working assembly 85. The rotating ring 831 is driven by the drive gear 825 to move the working assembly 85 along the circumference of the filter element, and the welding or pretreatment operation is completed by the outer shell column 851 and the working head 852. At the same time, electric energy is transmitted to the working assembly 85 through the conductive column 837, the conductive block 843 and the built-in wire, realizing efficient power supply of the welding head or the spray head; the telescopic electric pole 826 provides positioning and fixing functions, and the cooling flow channel 836 ensures the temperature stability of the system, so as to realize high-precision welding and multifunctional processing of the girth seam of the filter element. The overall process emphasizes the synchronization of workpiece rotation, working assembly 85 movement and power supply to ensure welding quality and device reliability.
