Description

Technical Field

[0001] This utility model relates to the field of valve press-fitting technology, and in particular to a valve core press-fitting mechanism. Background Technology

[0002] In the valve manufacturing industry, the press-fitting of valve cores is a crucial process to ensure valve sealing performance, structural stability, and service life. Its press-fitting accuracy and operational efficiency directly impact the overall quality of valve products and production efficiency. With the acceleration of industrialization, various valves are increasingly widely used in petroleum, chemical, water conservancy, and municipal industries. The market is placing higher demands on the automation level, finished product quality stability, and production continuity of valve production. As a core production equipment, the performance optimization of valve core press-fitting mechanisms has become an important direction for technological upgrading in the industry. Currently, traditional valve core pressing mechanisms suffer from two prominent problems during operation. Firstly, in the pressing and positioning stage, existing mechanisms often use simple tooling to roughly fix the lower module, lacking precise limiting and locking structures. When the pressing device applies pressure to the valve body, the lower module is prone to displacement due to the force, causing a deviation in the relative position between the valve body and the lower module. This results in inconsistent core pressing depth and loose sealing surfaces, severely affecting pressing accuracy and increasing the rate of defective products. Secondly, in the finished product collection stage, after the pressing device resets and the upper module rises, the finished valve typically falls directly from a height onto the support plate or worktable. Due to the lack of a buffer structure, the valve body is easily subjected to significant impact during the fall, potentially leading to valve deformation, seal damage, and other quality problems. Furthermore, manual collection not only increases labor costs but also reduces production continuity due to the intermittent nature of manual operation, making it difficult to meet the demands of efficient mass production. To address these technical problems, this application proposes a valve core pressing mechanism. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a valve core pressing mechanism. This device precisely locks the lower module position by embedding a limiting post into the bearing plate and using base bolts, ensuring no misalignment between the valve body and the lower module during pressing and guaranteeing pressing accuracy. Through the linkage of a rotating rod, gears, and racks, the buffer box automatically pours the finished product into the receiving box during stamping and accurately receives new finished products during resetting, reducing manual intervention and improving continuity. Furthermore, the buffer box's collection groove can stably hold the finished product, avoiding impact damage from direct drops in traditional operations and ensuring quality stability.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a valve core pressing mechanism, including an operating table, with guide columns fixedly connected to the left and right sides of the top of the operating table, a top plate fixedly connected to the top of the guide columns, a movable plate slidably connected to the outer wall of the guide columns, a stamping device inside the movable plate, connecting plates fixedly connected to the left and right sides of the bottom of the movable plate, a rotating rod one at the bottom of the left connecting plate, a rotating rod two at the bottom of the right connecting plate, a buffer box between the rotating rod one and the rotating rod two, a rotating component at the outer wall of the rotating rod one, a moving component at the outer wall of the rotating rod two, and a receiving box at the rear of the top of the operating table.

[0005] Furthermore, the rotating assembly includes a gear disposed on the outer wall of a rotating rod, a rack is meshed with the outer wall of the gear, a support plate is fixedly connected to the outer wall of the rack, a rack is fixedly connected to the top outer wall of the support plate, and the bottom of the support plate is fixedly connected to the top of the operating table.

[0006] Furthermore, the moving component includes a slider disposed on the outer wall of the rotating rod two, a support plate two fixedly connected to the top right side of the operating table, a groove opened on the left side of the support plate two, and the outer wall of the slider being slidably connected to the inside of the groove.

[0007] Furthermore, the stamping device is provided with an upper module at the bottom, and the upper module contains a valve body.

[0008] Furthermore, a limit post is fixedly connected to the top of the operating table, and bases are fixedly connected to the left and right sides of the front end of the top of the operating table. Bolts are provided on the top of the bases, and a bearing plate is provided on the top of the bases.

[0009] Furthermore, a lower module is provided inside the bearing plate, and the limiting post is located inside the bearing plate.

[0010] Furthermore, a collection groove is provided at the bottom of the buffer box for collecting the valve body.

[0011] This utility model has the following beneficial effects: In this utility model, the device precisely locks the position of the lower module by embedding the limiting post into the bearing plate and combining it with the base bolts, ensuring that the valve body and the lower module do not deviate during pressing, thus guaranteeing the pressing accuracy. At the same time, with the help of the linkage design of the rotating rod, gear and rack, the buffer box automatically pours the finished product into the receiving box during stamping, and can accurately receive the new finished product during resetting, reducing manual intervention and improving the continuity of operation.

[0012] In this invention, when the stamping device resets and the upper module rises, the buffer box rotates forward through the cooperation of gear and rack, accurately receiving the valve body that slides down from the upper module. Its collection groove can stably hold the finished product, avoiding the impact damage caused by the finished product falling directly onto the bearing plate in traditional operations, thus ensuring quality stability.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-4This utility model provides an embodiment of a valve core pressing mechanism, including an operating table 1. Guide columns 2 are fixedly connected to the left and right sides of the top of the operating table 1. A top plate 3 is fixedly connected to the top of the guide columns 2. A movable plate 5 is slidably connected to the outer wall of the guide columns 2. A stamping device 4 is installed inside the movable plate 5. Connecting plates 19 are fixedly connected to the left and right sides of the bottom of the movable plate 5. A rotating rod 12 is installed at the bottom of the left connecting plate 19, and a rotating rod 27 is installed at the bottom of the right connecting plate 19. A buffer box 11 is installed between the rotating rod 12 and the rotating rod 27. A gear 13 is provided on the outer wall of the operating platform 12. A rack 15 is meshed with the outer wall of the gear 13. A support plate 14 is fixedly connected to the outer wall of the rack 15. A rack 16 is fixedly connected to the top outer wall of the support plate 14. The bottom of the support plate 14 is fixedly connected to the top of the operating platform 1. A slider 18 is provided on the outer wall of the rotating rod 17. A support plate 21 is fixedly connected to the right side of the top of the operating platform 1. A groove 23 is opened on the left side of the support plate 21. The outer wall of the slider 18 is slidably connected to the inside of the groove 23. A receiving box 20 is provided on the rear side of the top of the operating platform 1. An upper module 7 is provided at the bottom of the stamping device 4. A valve body 22 is provided inside the upper module 7. A limit post 8 is fixedly connected to the top of the operating platform 1. A base 9 is fixedly connected to the left and right sides of the front end of the top of the operating platform 1. A bolt 10 is provided on the top of the base 9. A bearing plate 6 is provided on the top of the base 9. A lower module 24 is provided inside the bearing plate 6. The limit post 8 is located inside the bearing plate 6. The bottom of the buffer box 11 is provided with a collection groove 25 for collecting the valve body 22.

[0017] Specifically, when using this device, the valve body 22 to be pressed is placed inside the lower module 24, which is then placed in the support plate 6. The bolts 10 on the base 9 are fixed to the operating table 1, providing stable support for the support plate 6. The limiting post 8 is embedded in the support plate 6 to ensure accurate positioning of the lower module 24 and prevent displacement during pressing. When the stamping device 4 is started and drives the moving plate 5 to move downward along the guide post 2, the rotating rod 12 and the rotating rod 27 move downward with the connecting plate 19. The gear 13 of the rotating rod 12 meshes with the rack 15 at the middle of the support plate 14. The gear 13 rotates in the opposite direction, causing the rotating rod 12 to rotate in the opposite direction, causing the bottom of the buffer box 11 to rotate backward, pouring the valve body 22 in the collection trough 25 into the receiving box 20 on the rear side of the top of the operating table 1, thus realizing the automatic collection of the finished product after stamping. During this movement, the slider 18 on the outer wall of the rotating rod 17 always slides within the groove 23 inside the support plate 21. Even when the buffer box 11 is not in contact with the rack, its movement trajectory remains stable and will not deflect, always staying away from the stamping area. The groove 23 is enlarged at the corresponding locations where the rotating rod 17 and slider 18 need to rotate, to prevent the groove 23 from obstructing the slider 18 and causing jamming. The rotating rod 12 and the connecting plate 19 are hinged by bearings to ensure unobstructed rotation. The positioning function of the limit post 8 and the base 9 ensures the pressing accuracy and improves product quality.

[0018] After pressing, the stamping device 4 drives the moving plate 5 to reset upward along the guide column 2, and the connecting plate 19 drives the rotating rod 12 and the rotating rod 17 to move upward. At this time, the gear 13 on the outer wall of the rotating rod 12 first meshes with the rack 16 at the top of the support plate 14. The rotation of the gear 13 drives the rotating rod 12 to rotate, causing the bottom of the buffer box 11 to rotate forward. At this time, the valve body 22, which has been stamped inside the upper module 7, will slide into the collection groove 25 of the buffer box 11 during the upward process. The buffer box 11 avoids the valve body 22 from falling directly onto the bearing plate 6 and causing damage. Through the cooperation of the gear 13, rack 15 and rack 16, the buffer box 11 can rotate back and forth, thereby realizing the buffer support of the stamped finished product, avoiding product damage, and automatically pouring the product into the receiving box 20, realizing automated collection, so that the operator can continue the subsequent installation and improve work efficiency.

[0019] Working principle: When the device is working, the valve body 22 to be pressed is first placed in the lower module 24, which is placed on the support plate 6. The base 9 is fixed to the operating table 1 by bolts 10, providing stable support for the support plate 6. The limiting post 8 is embedded in the support plate 6 to ensure accurate positioning of the lower module 24. The pressing device 4 is started, which drives the moving plate 5 to move downward along the guide post 2. The connecting plate 19 then drives the rotating rod 12 and rotating rod 27 to move downward. The gear 13 of rotating rod 12 meshes with the rack 15 at the middle of the support plate 14. The gear 13 rotates in the opposite direction, causing rotating rod 12 to rotate in the opposite direction. The bottom of the buffer box 11 rotates backward, pouring the valve body 22 in the collection trough 25 into the collection box 20 to achieve automatic collection. At the same time, the slider of rotating rod 27... 18 slides within the groove 23 of the support plate 21 to ensure stable movement of the buffer box 11 and keep it away from the stamping area; after pressing, the stamping device 4 drives the moving plate 5 to reset upwards, and the connecting plate 19 drives the rotating rod 12 and the rotating rod 27 to move upwards. The gear 13 of the rotating rod 12 first meshes with the rack 26 at the top of the support plate 14. The rotation of the gear 13 causes the rotating rod 12 to rotate, and the bottom of the buffer box 11 rotates forward. The valve body 22, which has been stamped in the upper module 7, slides into the collection groove 25 of the buffer box 11 during the upward process, achieving buffering and avoiding damage. Through the cooperation of the gear 13, rack 15 and rack 26, the buffer box 11 rotates back and forth, which not only completes the buffering and receiving but also achieves automatic collection, improving work efficiency and product quality.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
