Description

Technical Field

[0001] This invention relates to the field of valve core welding technology, specifically to a welding workbench for a low-leakage solenoid valve core. Background Technology

[0002] Solenoid valves play a crucial role in industrial automation, intelligent control, and many other fields that require precise fluid control; however, manual welding is prone to defects.

[0003] Patent CN222711213U discloses an automatic valve core welding device, comprising a worktable, a support base, support frames, a robotic arm, a chuck, a fixture, and a welding mechanism. The support base is fixedly connected to the worktable. Multiple support frames are mounted on the support base to support multiple valve core bodies. A limiting groove, V-shaped, is formed at the top of each support frame, with the valve core body located inside the limiting groove and in contact with its wall. The device supports multiple valve core bodies to be welded on the respective support frames for welding. The valve core body is fed into a support frame with a V-shaped limiting groove on the top. This allows the valve core body to be stored and positioned by the groove wall while the support frame supports it. The valve core body can also slide along the limiting groove, facilitating the adjustment of the distance between adjacent valve core bodies. However, this device is not suitable for welding multiple valve cores at the same time, resulting in low work efficiency and long welding time. Therefore, a low-leakage solenoid valve core welding workbench is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a welding workbench for a low-leakage solenoid valve core, which addresses the shortcomings of the prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a welding workbench for a low-leakage solenoid valve core, comprising a welding table, a control console fixedly connected to the top of the welding table, a welding machine fixedly connected to the top of the welding table, a motor fixedly connected to the front side of the welding table, a threaded rod fixedly connected to the output end of the motor, a U-shaped rod threadedly connected to the circumferential surface of the threaded rod, a limiting mechanism for preventing displacement and loosening provided on both sides of the U-shaped rod, a cleaning mechanism for cleaning the surface provided on the outer surface of the limiting mechanism, a moving plate fixedly connected to the top of the U-shaped rod, and a placement plate fixedly connected to the inner wall of the moving plate; during welding, the placement plate is moved by the motor, reducing the number of welding operations and the overall welding time, further shortening the processing cycle, suitable for large-scale mass production, reducing production costs, and improving the versatility and production flexibility of the equipment; a clamping plate is slidably connected to the inner wall of the moving plate, and sliding... The welding table has a wheel, and an elastic telescopic rod is fixedly connected to the inner wall of the clamping plate. A pressure plate is fixedly connected to the elastic telescopic end of the elastic telescopic rod. A guide plate is fixedly connected to the top of the welding table. A door is rotatably connected to the left inner wall of the welding table. While adjusting the position of the valve core, the moving plate moves to drive the pressure plate to elastically clamp the valve core, preventing it from shifting due to external forces such as welding airflow and vibration during welding. This ensures the accuracy of the welding position, helps improve weld quality and valve core sealing performance, and also protects the valve core surface during clamping, preventing damage and ensuring the valve core's appearance quality and performance. The circumferential surface of the threaded rod is rotatably connected to the inner wall of the welding table, and the U-shaped rod is slidably connected to the inner wall of the welding table. Both sides of the moving plate contact the guide plate, and the inner wall of the guide plate has a sliding groove. The circumferential surface of the pulley contacts the sliding groove on the inner wall of the guide plate, and the bottom of the clamping plate contacts the top of the placement plate.

[0006] Preferably, the limiting mechanism includes a fixed block, and a sliding column is slidably connected to the inner wall of the fixed block via a spring. A limiting block is fixedly connected to the top of the sliding column. A slot is provided on the inner wall of the welding table. When the welded part is adjusted to the corresponding position, the U-shaped rod moves, causing the limiting block to move and contact the inner wall of the slot, thereby limiting the U-shaped rod and preventing weld deviation due to valve core position offset. This ensures that the welding size and shape meet the design requirements, thereby improving the sealing performance and performance of the valve core, preventing damage to the welding equipment due to abnormal contact, extending the service life of the equipment, and reducing equipment maintenance costs. The limiting column is fixedly connected to the inner wall of the U-shaped rod, and a reciprocating screw is rotatably connected to the inner wall of the U-shaped rod. A roller is fixedly connected to the circumferential surface of the reciprocating screw. The movable part is equipped with a scraper. After welding, the U-shaped rod moves, driving the scraper to reciprocate and clean the residue on the top of the welding table. This prevents the scraper from shifting or rotating during reciprocating movement. Cleaning the worktable avoids interference from impurities, ensuring a strong and well-sealed weld joint, improving the welding quality of the solenoid valve core, effectively protecting the worktable material, maintaining its structural integrity and surface precision, and extending the service life of the worktable. The fixed block is fixedly connected to both sides of the U-shaped rod. The outer surface of the limiting block contacts the inner wall of the slot. The circumferential surface of the first roller contacts the top of the welding table, and the first roller rotates through friction during movement. The bottom of the scraper contacts the top of the welding table, and the scraper is used to scrape the residue on the top of the welding table. The inner wall of the scraper contacts the circumferential surface of the limiting post.

[0007] Preferably, the cleaning mechanism includes a positioning block, the inner wall of which is rotatably connected to a striking rod via a torsion spring. An inclined block is fixedly connected to the top of the welding table. While cleaning the welding table, the scraper moves, causing the striking rod to strike the welding table, facilitating easier disassembly of components and improving the efficiency and convenience of the cleaning work, further enhancing the overall efficiency of the equipment. A telescopic rod is hinged to the right side of the machine door, and a sliding plate is hinged to the right side of the telescopic rod. A cleaning cylinder is rotatably connected to the inner wall of the sliding plate. Rollers are fixedly connected to the front and rear sides of the cleaning cylinder. A stop bar is fixedly connected to the inner wall of the welding table. When maintaining and cleaning the equipment, the machine door drives the cleaning cylinder to rotate and clean the inner wall of the welding table, preventing the cleaning cylinder from moving and causing damage. The offset effectively maintains the cleanliness of the workbench, creating a good environment for welding operations, ensuring stable equipment operation, reducing maintenance costs and downtime, extending the overall service life of the equipment, and improving the welding quality. The positioning block is fixedly connected to both sides of the scraper, and one end of the positioning block is provided with a torsion spring. The bottom of the striking rod contacts the top of the welding table, and the other end of the striking rod away from the welding table is provided with a torsion spring. The circumferential surface of the second roller contacts the bottom of the stop rod, and the stop rod is used to limit the movement of the second roller. The circumferential surface of the cleaning cylinder contacts the inner wall of the welding table, and the cleaning cylinder is used to clean the residue on the inner wall of the welding table. The cleaning cylinder contacts the inner wall of the sliding plate, and the second roller contacts the inner wall of the welding table.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This low-leakage solenoid valve core welding workbench, through the coordinated operation of the welding table, control console, welding machine, machine door, motor, threaded rod, U-shaped rod, moving plate, placement plate, clamping plate, pulley, guide plate, elastic telescopic rod, and pressure plate, allows the placement plate to move via the motor during welding, reducing the number of welding operations and overall welding time, further shortening the processing cycle. This makes it suitable for large-scale mass production, reducing production costs and improving the equipment's versatility and production flexibility. While adjusting the valve core position, the moving plate moves, causing the pressure plate to elastically clamp the valve core, preventing displacement due to welding airflow, vibration, or other external forces during welding. This ensures accurate welding position, improves weld quality and valve core sealing performance, and protects the valve core surface during clamping, preventing damage and ensuring the valve core's appearance quality and performance.

[0010] 2. The welding worktable for a low-leakage solenoid valve core utilizes the coordinated operation of a fixed block, sliding column, limiting block, and slot. When the welded part is adjusted to the corresponding position, the U-shaped rod moves, causing the limiting block to contact the inner wall of the slot, thereby limiting the U-shaped rod and preventing weld deviation due to valve core position offset. This ensures that the weld size and shape meet design requirements, thereby improving the sealing performance and usability of the valve core. It also prevents damage to the welding equipment due to abnormal contact, extends equipment service life, and reduces equipment maintenance costs.

[0011] 3. This low-leakage solenoid valve core welding worktable, through the coordinated operation of the reciprocating screw, limit post, roller, and scraper, after welding, the U-shaped rod moves to drive the scraper to reciprocate and clean the residue on the top of the welding table. This prevents the scraper from deviating or rotating during the reciprocating movement. Cleaning the worktable avoids interference from impurities, ensures a strong and well-sealed weld joint, improves the welding quality of the solenoid valve core, effectively protects the worktable material, maintains its structural integrity and surface precision, and extends the service life of the worktable.

[0012] 4. The welding workbench for the low-leakage solenoid valve core, through the coordinated operation of the positioning block, the striking rod, and the inclined block, cleans the welding table while the scraper moves to drive the striking rod to strike the welding table. It also makes it easier to disassemble the parts, improving the efficiency and convenience of the cleaning work, and further improving the overall working efficiency of the equipment.

[0013] 5. This low-leakage solenoid valve core welding workbench, through the coordinated operation of the sliding plate, cleaning cylinder, rollers, and stop bar, allows the machine door to drive the cleaning cylinder to rotate and clean the inner wall of the welding table during equipment maintenance and cleaning. This prevents the cleaning cylinder from shifting during movement, effectively maintaining the cleanliness of the workbench, creating a good environment for welding operations, ensuring stable equipment operation, reducing maintenance costs and downtime, extending the overall service life of the equipment, and improving the welding quality of the equipment.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-8 One embodiment of the present invention is: a welding workbench for a low-leakage solenoid valve core, including a welding table 1, a control console 2 fixedly connected to the top of the welding table 1, a welding machine 3 fixedly connected to the top of the welding table 1, a motor 7 fixedly connected to the front side of the welding table 1, a threaded rod 8 fixedly connected to the output end of the motor 7, a U-shaped rod 9 threadedly connected to the circumferential surface of the threaded rod 8, a limiting mechanism 5 for preventing displacement and loosening provided on both sides of the U-shaped rod 9, a cleaning mechanism 6 for cleaning the surface provided on the outer surface of the limiting mechanism 5, a moving plate 10 fixedly connected to the top of the U-shaped rod 9, and a placement plate 11 fixedly connected to the inner wall of the moving plate 10;

[0025] During welding, workers can place multiple solenoid valve cores onto the placement plate 11. Then, motor 7 can be started. Motor 7 drives threaded rod 8 to rotate via its output end. The rotation of threaded rod 8 drives U-shaped rod 9 through the threaded groove on its circumferential surface. U-shaped rod 9 then drives moving plate 10, which in turn moves placement plate 11. The movement of placement plate 11 brings the solenoid valve cores on the inner wall to their corresponding positions. Welding machine 3 is then started to weld the solenoid valve cores on placement plate 11. After welding the first row, motor 7 can drive placement plate 11 to move, allowing welding of subsequent solenoid valve cores. Multi-row welding allows for simultaneous welding of multiple parts, reducing the number of welding operations and overall welding time, further shortening the processing cycle. This is suitable for large-scale mass production. Adjusting the valve core position can accommodate the welding needs of various valve cores, eliminating the need for dedicated welding equipment for each type of valve core, reducing production costs, and improving the equipment's versatility and production flexibility.

[0026] A clamping plate 12 is slidably connected to the inner wall of the movable plate 10. Pulleys 13 are installed on both sides of the clamping plate 12. An elastic telescopic rod 15 is fixedly connected to the inner wall of the clamping plate 12. A pressure plate 16 is fixedly connected to the elastic telescopic end of the elastic telescopic rod 15. A guide plate 14 is fixedly connected to the top of the welding table 1. An organic door 4 is rotatably connected to the left inner wall of the welding table 1. The circumferential surface of the threaded rod 8 is rotatably connected to the inner wall of the welding table 1. The U-shaped rod 9 is slidably connected to the inner wall of the welding table 1. Both sides of the movable plate 10 are in contact with the guide plate 14, and the inner wall of the guide plate 14 is provided with a sliding groove. The circumferential surface of the pulley 13 is in contact with the sliding groove of the inner wall of the guide plate 14. The bottom of the clamping plate 12 is in contact with the top of the placement plate 11.

[0027] While adjusting the position of the valve core, the moving plate 10 moves, causing the clamping plate 12 to move. The clamping plate 12 then moves the pulley 13. The pulley 13 moves and contacts the inner wall groove of the guide plate 14 through its circumferential surface, causing the pulley 13 to move along the inner wall of the guide plate 14. This causes the pulley 13 to move the clamping plate 12 downward, which in turn moves the elastic telescopic rod 15 downward. The elastic telescopic rod 15 then moves the pressure plate 16 downward, allowing the pressure plate 16 to elastically clamp the valve core through the elastic telescopic end of the elastic telescopic rod 15. As the movement continues, the pulley 13 can move upward through the inner wall of the guide plate 14, thereby releasing the clamping of the solenoid valve core. This prevents the valve core from shifting due to external forces such as welding gas flow and vibration during welding, ensuring the accuracy of the welding position, improving weld quality and valve core sealing performance, and protecting the valve core surface during clamping. This prevents damage to the valve core surface and ensures the appearance quality and performance of the valve core.

[0028] Working principle: During welding, the motor 7 drives the placement plate 11 to move, thereby adjusting the multiple rows of welded parts, further shortening the processing cycle, making it suitable for large-scale mass production, and improving the equipment's versatility and production flexibility; while adjusting the valve core position, the moving plate 10 moves to drive the pressure plate 16 to elastically clamp the valve core, preventing it from shifting due to external forces such as welding airflow and vibration during the welding process, ensuring the accuracy of the welding position, not damaging the valve core surface, and ensuring the appearance quality and performance of the valve core.

[0029] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the limiting mechanism 5 includes a fixing block 51, the inner wall of the fixing block 51 is slidably connected to a sliding column 52 by a spring, the top of the sliding column 52 is fixedly connected to a limiting block 53, and the inner wall of the welding table 1 is provided with a slot 54.

[0030] When the welded part is adjusted to the corresponding position, the U-shaped rod 9 moves, driving the fixed block 51 to move. The fixed block 51 drives the sliding column 52 to move, and the sliding column 52 drives the limiting block 53 to move. The limiting block 53 moves and contacts the slot 54 through the inclined surface, thereby driving the slot 54 to move. When the slot 54 is in the corresponding slot 54, the sliding column 52 will move through the spring, and the sliding column 52 will drive the limiting block 53 to move. The limiting block 53 will contact the inner wall of the slot 54, thereby limiting the U-shaped rod 9, avoiding weld deviation due to valve core position offset, ensuring that the weld size and shape meet the design requirements, thereby improving the sealing performance and performance of the valve core, preventing damage to the welding equipment due to abnormal contact, extending the service life of the equipment, and reducing equipment maintenance costs.

[0031] The inner wall of the U-shaped rod 9 is fixedly connected to a limiting post 56, and the inner wall of the U-shaped rod 9 is rotatably connected to a reciprocating screw 55. The circumferential surface of the reciprocating screw 55 is fixedly connected to a roller 57, and the circumferential surface of the reciprocating screw 55 is movably connected to a scraper 58. The fixing block 51 is fixedly connected to both sides of the U-shaped rod 9. The outer surface of the limiting block 53 contacts the inner wall of the slot 54. The circumferential surface of the roller 57 contacts the top of the welding table 1, and the roller 57 will rotate by friction when it moves. The bottom of the scraper 58 contacts the top of the welding table 1, and the scraper 58 will be used to scrape the residue on the top of the welding table 1. The inner wall of the scraper 58 contacts the circumferential surface of the limiting post 56.

[0032] After welding, the U-shaped rod 9 moves, driving the reciprocating screw 55 to move. The reciprocating screw 55 drives the roller 57 to move. The roller 57 moves and contacts the top of the welding table 1 through its circumferential surface, thereby causing the roller 57 to rotate due to friction. The roller 57 drives the reciprocating screw 55 to rotate. The rotation of the reciprocating screw 55 drives the scraper 58 to move back and forth through the reciprocating groove on the circumferential surface. The scraper 58 moves back and forth to clean the residue on the top of the welding table 1. The limiting post 56 limits the scraper 58 to prevent it from deviating during reciprocating movement. Cleaning the worktable can avoid interference from impurities, ensure that the welded joint is firm and well-sealed, improve the welding quality of the solenoid valve core, effectively protect the worktable material, maintain its structural integrity and surface accuracy, and extend the service life of the worktable.

[0033] Working principle: When the welded part is adjusted to the corresponding position, the U-shaped rod 9 moves and drives the limiting block 53 to move and contact the inner wall of the slot 54, thereby limiting the U-shaped rod 9 and avoiding weld deviation caused by valve core position offset, thus improving the sealing performance and service performance of the valve core; after welding, the U-shaped rod 9 moves and drives the scraper 58 to move back and forth to clean the residue on the top of the welding table 1, ensuring that the welded joint is firm and well sealed, and improving the welding quality of the solenoid valve core.

[0034] The cleaning mechanism 6 includes a positioning block 61, and the inner wall of the positioning block 61 is rotatably connected to a striking rod 62 via a torsion spring. The top of the welding table 1 is fixedly connected to an inclined block 63.

[0035] While cleaning the welding table 1, the movement of the scraper 58 will drive the positioning block 61 to move, and the positioning block 61 will drive the striking rod 62 to move. As the striking rod 62 moves, it will contact the top inclined surface of the inclined block 63 through the bottom inclined surface, thereby driving the striking rod 62 to rotate. When the striking rod 62 leaves the inclined block 63, the striking rod 62 will be reset through the torsion spring connected to the inner wall of the positioning block 61, so that the striking rod 62 can strike the welding table 1, shake off the residue in the hole of the welding table 1, and make it easier to disassemble the parts, improve the efficiency and convenience of the cleaning work, and further improve the overall working efficiency of the equipment.

[0036] A telescopic rod 64 is hinged to the right side of the machine door 4, and a sliding plate 65 is hinged to the right side of the telescopic rod 64. A cleaning cylinder 66 is rotatably connected to the inner wall of the sliding plate 65. Rollers 67 are fixedly connected to the front and rear sides of the cleaning cylinder 66. A stop bar 68 is fixedly connected to the inner wall of the welding table 1. A positioning block 61 is fixedly connected to both sides of the scraper 58, and one end of a torsion spring is provided on the inner wall of the positioning block 61. The bottom of the striking rod 62 contacts the top of the welding table 1, and the other end of the torsion spring is provided on the end of the striking rod 62 away from the welding table 1. The circumferential surface of the roller 67 contacts the bottom of the stop bar 68, and the stop bar 68 is used to limit the roller 67. The circumferential surface of the cleaning cylinder 66 contacts the inner wall of the welding table 1, and the cleaning cylinder 66 is used to clean the residue on the inner wall of the welding table 1. The cleaning cylinder 66 contacts the inner wall of the sliding plate 65, and the roller 67 contacts the inner wall of the welding table 1.

[0037] When maintaining and cleaning the equipment, the operator manually pulls the machine door 4. The door 4 rotates, moving the telescopic rod 64 through the hinge point. The telescopic rod 64 then pulls the cleaning cylinder 66 through the hinge point, moving the cleaning cylinder 66. The cleaning cylinder 66 then moves the roller 67. The roller 67 contacts the bottom of the stop rod 68, causing friction and rotation. The roller 67 then rotates the cleaning cylinder 66 to clean the inner wall of the welding table 1. The stop rod 68 limits the movement of the cleaning cylinder 66, preventing it from shifting during movement. This effectively maintains the cleanliness of the workbench, creates a good environment for welding operations, ensures stable equipment operation, reduces maintenance costs and downtime, extends the overall service life of the equipment, and improves the welding quality.

[0038] Working principle: While cleaning the welding table 1, the scraper 58 moves, driving the striking rod 62 to strike the welding table 1, improving the efficiency and convenience of the cleaning work, and further improving the overall working efficiency of the equipment; when maintaining and cleaning the equipment, the machine door 4 drives the cleaning cylinder 66 to rotate and clean the inner wall of the welding table 1, preventing the cleaning cylinder 66 from shifting when moving, effectively maintaining the cleanliness of the workbench, creating a good environment for welding operations, making the overall service life of the equipment longer, and improving the welding quality of the equipment.
