Description

Technical Field

[0001] This utility model relates to the field of head support frame technology, and in particular to a combined adjustable-size internal head support frame. Background Technology

[0002] An end cap is a component used to seal the end of a container and isolate the internal and external media. It is also called an end cap and is a part of the container. It is connected to the cylinder by welding and is suitable for various containers. After the end cap is manufactured, it is essential to grind it. It is a surface modification technology. It generally refers to a processing method that uses a rough object to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. The support device used for grinding is to hold the end cap in place, provide support for the end cap, and ensure that the end cap does not collapse or tilt, thus ensuring successful grinding.

[0003] For example, patent number CN216828110U discloses a head stamping support device. The adjustment mechanism and the support platform work together to adjust the position of the head plate so that the head plate can be aligned directly below the stamping position of the hydraulic press. At the same time, the structural shape of the connecting seat matches the support platform and the support seat, which facilitates the removal of the stamped head and ensures the stability of the support platform during the stamping process, while not affecting the removal of the oxide scale that falls off the head plate. For example, patent number CN211218416U discloses a support structure for processing end cap structures. Through the arrangement of a support base, an electric push rod, a tray, and a buffer layer, the electric push rod can be lifted upwards to lift the end cap placed on the buffer layer, separating the end cap from the support base. This avoids the situation where the end cap is stuck with the support base, making it impossible to remove the end cap, thus facilitating the removal of the bottom end cap. Through the arrangement of a cylinder, push block, moving rod, support rod, slider, sliding sleeve, clamping block, fastening layer, bolts, and tightening nut, if end caps are stacked and stuck, two sets of clamping blocks can be fastened to the end cap, and then the cylinder can be activated to lift the clamped end cap, thus separating the end cap. This simplifies the removal of stacked end caps.

[0004] However, most existing head support frames are fixed structures, while the sizes of the heads to be processed vary. The support frames cannot be quickly adjusted and adapted to different sizes of heads, which affects the efficiency of head processing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a modular adjustable-size internal support frame for end caps, which solves the problem that most existing end cap support frames are fixed structures, while the sizes of the end caps to be processed vary, and the support frame cannot be quickly adjusted and adapted to different sizes of end caps, thus affecting the work efficiency of end cap processing.

[0006] The technical solution of this utility model is as follows: a combined adjustable-size head inner support frame, including a support base and a head seat. Displacement seats are movably connected to the outer sides of the four ends of the head seat on the top surface of the support base. A transmission assembly is provided below the displacement seats on the inner side of the support base. The transmission assembly is used to connect the displacement seats and the support base. A buffer seat is fixedly connected to the top of the displacement seat. A buffer rod is movably connected to the inner side of the buffer seat. A connecting seat is provided at the top of the buffer rod. When the head seat is connected to the displacement seat, the head seat is connected to the displacement seat through the connecting seat. Buffer blocks are provided on both sides of the buffer rod on the inner side of the buffer seat. When the head seat is subjected to pressure and moves downward, the buffer rod distributes the pressure of the head seat to the two buffer blocks. The transmission assembly includes a servo motor. A transmission ring is fixedly connected to the output end of the servo motor. A transmission rod is rotatably connected to the outer side of the transmission ring. The top of the transmission rod extends to the outer side of the bottom end of the displacement seat. When the servo motor drives the transmission ring to rotate, the transmission ring, in conjunction with the transmission rod, drives the buffer seat to move on the top surface of the support base.

[0007] Preferably, a control panel is fixedly connected to the front end of the support base. The control panel is electrically connected to the transmission component. When the support base is powered on, the transmission component can be started through the control panel.

[0008] Preferably, the top of the connecting seat is provided with a screw hole, and when the end cap seat is connected to the connecting seat, the end cap seat can be fixedly connected to the connecting seat by bolts.

[0009] Preferably, a guide groove is provided on the top surface of the support base below the displacement seat, and the bottom end of the displacement seat extends to the inner side of the guide groove. When the displacement seat moves, the displacement seat moves inside the guide groove.

[0010] Preferably, there are four displacement seats, and the number of transmission rods is the same as the number of displacement seats. The transmission rods correspond one-to-one with the displacement seats. The top of the transmission rod is provided with a rack on the outside of the displacement seat. Both ends of the transmission rod are provided with transmission gears. The two transmission gears are respectively connected to the rack and the transmission ring. When the transmission ring drives the transmission rod to rotate, the transmission rod, in conjunction with the transmission gears and the rack, drives the displacement seat to perform displacement movement.

[0011] Preferably, the buffer rod and the contact block are an integral structure, and both ends of the contact block and the intersection of the buffer block and the contact block are inclined surfaces, so that the buffer block fits into the contact block through the inclined surfaces.

[0012] Preferably, a movable groove is provided below the buffer block on the inner side of the displacement seat, the bottom end of the buffer block extends to the inner side of the movable groove, and a connecting spring is fixedly connected to the inner wall of the movable groove. The buffer block is movably connected to the displacement seat through the connecting spring.

[0013] The beneficial effects of this utility model are: This modular adjustable-size head support frame uses a servo motor-driven transmission mechanism to achieve synchronous radial movement of four displacement seats. It can quickly and accurately adapt to the inner cavity of heads with different diameters, supporting various specifications of heads without replacing parts, significantly improving the equipment's versatility and efficiency. The four displacement seats are arranged circumferentially and symmetrically, with a synchronous transmission structure to ensure that the head seat is always centered and evenly stressed, effectively avoiding uneven loading or local stress concentration, improving support reliability. Furthermore, the mechanical buffer structure using inclined guides and compression springs effectively prevents the inner wall of the head from being crushed or deformed during operation.

Detailed Implementation

[0016] 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.

[0017] Please see Figures 1-4This utility model provides an embodiment: a combined adjustable-size head inner support frame, including a support base 1 and a head seat 3. Displacement seats 5 are movably connected to the outer sides of the four ends of the head seat 3 on the top surface of the support base 1. A transmission assembly is provided below the displacement seats 5 on the inner side of the support base 1, for connecting the displacement seats 5 and the support base 1. A buffer seat 6 is fixedly connected to the top of the displacement seat 5, and a buffer rod 7 is movably connected to the inner side of the buffer seat 6. A connecting seat 8 is provided at the top of the buffer rod 7. When the head seat 3 is connected to the displacement seat 5, the head seat 3 connects to the displacement seat 5 via the connecting seat 8. The shift seat 5 is connected, and buffer blocks 9 are provided on both sides of the buffer rod 7 inside the buffer seat 6. When the end cap 3 is subjected to pressure and moves downward, the buffer rod 7 distributes the pressure of the end cap 3 to the two buffer blocks 9. The transmission assembly includes a servo motor 10. The output end of the servo motor 10 is fixedly connected to a transmission ring 11. A transmission rod 12 is rotatably connected to the outside of the transmission ring 11. The top end of the transmission rod 12 extends to the outside of the bottom end of the shift seat 5. When the servo motor 10 drives the transmission ring 11 to rotate, the transmission ring 11 cooperates with the transmission rod 12 to drive the buffer seat 6 to move on the top surface of the support base 1.

[0018] Please see Figures 1-2 In this embodiment, a control panel 2 is fixedly connected to the front end of the support base 1. The control panel 2 is electrically connected to the transmission component. When the support base 1 is powered on, the transmission component can be started through the control panel 2. A screw hole is provided at the top of the connecting seat 8. When the end cap 3 is connected to the connecting seat 8, the end cap 3 can be fixedly connected to the connecting seat 8 by bolts. A guide groove 4 is provided below the displacement seat 5 on the top surface of the support base 1. The bottom end of the displacement seat 5 extends to the inner side of the guide groove 4. When the displacement seat 5 moves, the displacement seat 5 moves inside the guide groove 4. Wear-resistant slide rails or ball bearing guide sleeves are provided on the inner walls of both sides of the guide groove 4. A slider or roller is correspondingly provided at the bottom end of the displacement seat 5 to reduce the frictional resistance during the displacement process and improve the adjustment accuracy and service life.

[0019] Please see Figures 3-4In this embodiment, four displacement seats 5 are provided, and the number of transmission rods 12 is the same as the number of displacement seats 5. Each transmission rod 12 corresponds to one displacement seat 5. A rack 14 is provided at the top of the transmission rod 12 on the outside of the displacement seat 5. Transmission gears 13 are provided at both ends of the transmission rod 12. The two transmission gears 13 are respectively connected to the rack 14 and the transmission ring 11. When the transmission ring 11 drives the transmission rod 12 to rotate, the transmission rod 12, in conjunction with the transmission gears 13 and the rack 14, drives the displacement seat 5 to move. The buffer rod 7 and the contact block 16 are an integral structure. Both ends of the contact block 16 and the intersection of the buffer block 9 and the contact block 16 are inclined surfaces. The buffer block 9 fits against the contact block 16 through the inclined surfaces. The outer surface of the contact block 16 is covered with a flexible buffer layer made of rubber or polyurethane material. This flexible buffer layer is used to reduce the rigid impact on the inner wall of the head during the support process and prevent scratches or deformation. The buffer block 9 is provided with a movable groove 17 on the inner side of the displacement seat 5. The bottom end of the buffer block 9 extends to the inner side of the movable groove 17. A connecting spring 18 is fixedly connected to the inner wall of the movable groove 17. The buffer block 9 is movably connected to the displacement seat 5 through the connecting spring 18. The connecting spring 18 is a compression spring with adjustable preload. When the contact block 16 is subjected to the reaction force of the inner wall of the head, the buffer block 9 overcomes the elastic force of the connecting spring 18 and retracts downward to achieve secondary buffering and improve the stability and safety during the support process.

[0020] When in operation, the power is turned on and the device is started. The servo motor 10 drives the transmission ring 11, which is fixedly connected to its output end, to rotate. The transmission ring 11 meshes with the rack 14 on the transmission rod 12 through the transmission gears 13 at both ends, so that the four transmission rods 12 rotate synchronously. The rack 14 generates linear motion under the drive of the transmission gears 13, pushing the corresponding displacement seat 5 to move radially outward (or inward) along the guide groove 4 on the top surface of the support base 1. Since the four displacement seats 5 are arranged circumferentially symmetrically and have the same transmission structure, the buffer seats 6 move synchronously, and the end cap 3 is always centered and evenly stressed. When the outer edge of the end cap 3 contacts the inner wall of the end cap, the position of the displacement seat 5 is further finely adjusted until the end cap 3 is completely... The head seat 3 is fitted to the curved surface of the end cap, allowing for the fixation and stable support of end cap seats 3 of different sizes. During the processing or handling of the end cap, if the end cap seat 3 is subjected to external pressure and displaces downward, the pressure is transmitted to the buffer rod 7 through the connecting seat 8. The buffer rod 7 moves downward in conjunction with the contact block 16, and its two inclined surfaces press against the buffer block 9, causing the buffer block 9 to slide downward along the movable groove 17. The buffer block 9 also compresses the connecting spring 18 below, absorbing the impact energy and achieving primary elastic buffering. The flexible buffer layer (rubber or polyurethane) further alleviates local stress concentration and prevents damage to the inner wall of the end cap. When the external force is removed, the restoring force of the connecting spring 18 pushes the buffer block 9 to reset, causing the contact block 16 and the end cap seat 3 to return to their original positions. Compared to the prior art document CN216828110U, a head stamping support device, the position of the head plate is adjusted by the cooperation of the adjustment mechanism and the support platform, so that the head plate can be aligned directly below the stamping position of the hydraulic press. At the same time, the structural shape of the connecting seat is matched with the support platform and the support seat, which facilitates the removal of the stamped head on the one hand, and ensures the stability of the support platform during the stamping process on the other hand, without affecting the removal of the oxide scale that falls off the head plate. CN211218416U describes a support structure for processing end cap structures. Through the inclusion of a support base, electric push rod, pallet, and buffer layer, the electric push rod can be lifted upwards to lift the end cap placed on the buffer layer, separating the end cap from the support base. This avoids the situation where the end cap is stuck with the support base, making it impossible to remove the end cap, thus facilitating the removal of the bottom end caps. Furthermore, through the inclusion of a cylinder, push block, moving rod, support rod, slider, sliding sleeve, clamping block, fastening layer, bolts, and tightening nut, if end caps become stuck and cannot be separated, two sets of clamping blocks can be fastened to the end caps, and then the cylinder can be activated to lift the clamped end caps, thus separating them. This simplifies the removal of stacked end caps. This application utilizes a servo motor-driven transmission mechanism to achieve synchronous radial movement of four displacement seats. This enables rapid and precise adaptation to the inner cavities of end caps of different diameters, supporting various end cap specifications without the need to replace parts. This significantly improves the equipment's versatility and efficiency. The four displacement seats are arranged circumferentially and symmetrically, working in conjunction with a synchronous transmission structure to ensure that the end cap seats are always centered and evenly stressed, effectively avoiding uneven loading or localized stress concentration, thus improving support reliability. Furthermore, the use of a sloping guide combined with a compression spring mechanical buffer structure effectively prevents the inner wall of the end cap from being damaged or deformed during operation.

[0021] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
