Abstract
Description
Technical Field
[0001] This utility model belongs to the field of valve assembly technology, and specifically relates to a valve assembly anti-misalignment structure. Background Technology
[0002] Valve assembly is the process of combining, positioning, and connecting components such as valve body, valve cover, valve core, valve stem, seals, and drive device according to design requirements to form a complete mechanical device with functions such as cutting off, regulating, or controlling fluids. It covers parts inspection, cleaning, precise installation, sealing debugging, and performance testing. Its quality directly affects the valve's sealing performance, opening and closing function, and adaptability to operating conditions, and is a key manufacturing link to ensure the safe and reliable operation of valves in industrial pipeline systems.
[0003] However, while traditional manual installation methods are flexible, they have significant limitations when faced with precision anti-misalignment requirements during valve assembly. Manual operation is affected by factors such as individual skill level and fatigue, making it difficult to maintain high-precision positioning during component docking and installation. This can easily lead to deviations and misalignment of sealing surfaces, which not only reduces assembly efficiency but may also extend the production cycle due to rework.
[0004] To address the aforementioned issues, this application proposes a valve assembly anti-misalignment structure. Utility Model Content
[0005] To address the aforementioned problems in the existing technology, this utility model provides a valve assembly anti-misalignment structure, which has the characteristic of preventing misalignment during valve assembly.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve assembly anti-misalignment structure, comprising a support plate, a controller, two brake motors, and two sets of first electric push rods respectively disposed on the upper surface of the support plate, two first slot frames fixedly connected to the upper surface of the support plate, two sliding blocks slidably connected inside each first slot frame, a second slot frame fixedly connected to the upper surface of each set of sliding blocks, the telescopic end of each first electric push rod fixedly connected to the side of each set of sliding blocks that is away from each other, a sliding frame slidably connected inside each second slot frame, a threaded rod rotatably connected to the inner wall of each second slot frame, the outer surface of each threaded rod threadedly connected to the inner wall of the sliding frame, the power output end of each brake motor fixedly connected to the left end of the threaded rod, two electric telescopic columns fixedly connected to the upper surface of each sliding frame, a second electric push rod disposed at the telescopic end of each electric telescopic column, and a limit plate fixedly connected to the telescopic end of each second electric push rod.
[0007] As a preferred embodiment of this utility model, the bottom surface of the support plate is fixedly connected to two sets of support columns, and the bottom end of each support column is fixedly connected to a support base.
[0008] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the bottom surface of the controller, and the bottom surface of the connecting plate is fixedly connected to the upper surface of the support plate.
[0009] As a preferred technical solution of this utility model, each group of first electric push rods has a fixed frame fixedly connected to the ends of the first electric push rods that are far apart from each other, and the sides of the fixed frames that are close to each other are fixedly connected to the front and back of the support plate, respectively.
[0010] As a preferred embodiment of this utility model, each of the brake motors is fixedly connected to a connecting seat on its bottom surface, and the right side of each connecting seat is fixedly connected to the left side of the second slot frame.
[0011] As a preferred embodiment of this utility model, each of the electric telescopic columns has a connecting frame fixedly connected to its telescopic end, and the inner wall of each connecting frame is fixedly connected to the outer surface of the second electric push rod.
[0012] As a preferred technical solution of this utility model, each of the connecting frames is fixedly connected to a reinforcing ring on one of its opposite sides, and the inner wall of each reinforcing ring is fixedly connected to the outer surface of the second electric push rod.
[0013] As a preferred technical solution of this utility model, a protective pad is fixedly connected to one side of each group of limiting plates that are close to each other, and each protective pad is made of rubber.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the integrated control of the controller, the collaborative operation of each execution component can be precisely scheduled. At the same time, the telescopic movement of the second electric push rod can drive the two sets of limit plates to move closer or further away synchronously, and the valve component to be assembled can be stably fixed through flexible clamping. Then, the height adjustment function of the electric telescopic column can be used to adapt to the assembly height requirements of different work positions. Meanwhile, the brake motor drives the threaded rod to rotate through forward and reverse rotation, and drives the sliding frame to slide linearly in the second slot frame through thread transmission, realizing fine adjustment of the horizontal position. The first electric push rod pushes the sliding block to slide in the first slot frame, thereby driving the entire assembly mechanism to move in the horizontal direction to complete the component docking. This structure, through the precision control of multi-axis linkage, realizes spatial position calibration and error compensation during valve assembly, effectively avoiding the misalignment problem caused by positioning deviation in traditional manual assembly, and significantly improving the assembly accuracy.

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. Example
[0022] Please see Figure 1-4This utility model provides the following technical solution: a valve assembly anti-misalignment structure, including a support plate 1, with a controller 2, two brake motors 8, and two sets of first electric push rods 7 respectively arranged on the upper surface of the support plate 1. Two first slot frames 3 are fixedly connected to the upper surface of the support plate 1, and two sliding blocks 9 are slidably connected inside each first slot frame 3. A second slot frame 15 is fixedly connected to the upper surface of each set of sliding blocks 9. The telescopic end of each first electric push rod 7 is fixedly connected to the side of each set of sliding blocks 9 that is away from each other. Each slot frame 15 has a sliding frame 13 slidably connected inside. Each second slot frame 15 has a threaded rod 12 rotatably connected to its inner wall. The outer surface of each threaded rod 12 is threadedly connected to the inner wall of the sliding frame 13. The power output end of each brake motor 8 is fixedly connected to the left end of the threaded rod 12. Each sliding frame 13 has two electric telescopic columns 14 fixedly connected to its upper surface. Each electric telescopic column 14 has a second electric push rod 16 at its telescopic end. Each second electric push rod 16 has a limit plate 19 fixedly connected to its telescopic end.
[0023] In this embodiment, the threaded rod 12 and the sliding frame 13 are connected by a precision trapezoidal thread pair. When the brake motor 8 drives the threaded rod 12 to rotate clockwise or counterclockwise, the sliding frame 13 will achieve bidirectional linear motion along the axis of the threaded rod 12 based on the thread transmission principle.
[0024] Specifically, two sets of support columns 6 are fixedly connected to the bottom surface of the support plate 1. Each support column 6 is fixedly connected to a support base 4 at its bottom end. In this embodiment, the support column 6 is used to fix the support base 4 to the support plate 1, and the support base 4 increases the contact area to make the support plate 1 stable.
[0025] Specifically, a connecting plate 5 is fixedly connected to the bottom surface of the controller 2. The bottom surface of the connecting plate 5 is fixedly connected to the upper surface of the support plate 1. In this embodiment, the controller 2 can be fixed by the connecting plate 5. At the same time, the controller 2 adopts a PLC programmable logic controller, which is a digital computing and operating electronic system designed for industrial automation control scenarios. It stores instructions through a programmable memory and can perform functions such as logical operations, sequential control, timing, counting and arithmetic operations, and control various industrial equipment or production processes in digital or analog form.
[0026] Specifically, each set of first electric push rods 7 has a fixed bracket 11 fixedly connected to the ends of the first electric push rods 7 that are far apart from each other, and the sides of each set of fixed brackets 11 that are close to each other are fixedly connected to the front and back of the support plate 1 respectively. In this embodiment, the fixed bracket 11 is used to anchor the first electric push rods 7 to the support plate 1 to ensure the stability of their extension and retraction.
[0027] Specifically, each brake motor 8 has a connecting seat 10 fixedly connected to its bottom surface, and the right side of each connecting seat 10 is fixedly connected to the left side of the second slot frame 15. In this embodiment, the connecting seat 10 is used to support the brake motor 8, which is a power device integrating an electromagnetic braking device. The electromagnetic brake at the rear end of its stator housing is linked to the main shaft through a mechanical structure.
[0028] Specifically, each telescopic column 14 is fixedly connected to a connecting frame 18 at its telescopic end. The inner wall of each connecting frame 18 is fixedly connected to the outer surface of the second electric push rod 16. In this embodiment, the connecting frame 18 serves as a transmission connector, enabling the electric telescopic column 14 to drive the second electric push rod 16 to move synchronously.
[0029] Specifically, each set of connecting frames 18 has a reinforcing ring 17 fixedly connected to one of its opposite sides. The inner wall of each reinforcing ring 17 is fixedly connected to the outer surface of the second electric push rod 16. In this embodiment, the second electric push rod 16 can be reinforced to the connecting frame 18 by means of the reinforcing ring 17, thereby improving the firmness of the second electric push rod 16.
[0030] Specifically, each set of limiting plates 19 has a protective pad 20 fixedly connected to one side of each other. Each protective pad 20 is made of rubber. In this embodiment, the rubber protective pad 20 can provide buffer protection when fixing the valve to avoid damage to the workpiece surface.
[0031] The working principle and usage process of this utility model are as follows: During use, the operator first places the valve component to be assembled, such as the valve body or valve cover, between the two sets of limiting plates 19. The equipment is started via controller 2, and the second electric push rod 16 is adjusted. Its telescopic end drives the limiting plate 19 to move inward, using the rubber protective pad 20 to flexibly clamp the component. Simultaneously, the electric telescopic column 14 is adjusted via controller 2 to adjust the vertical position of the limiting plate 19 according to the workstation height, completing the initial positioning. Subsequently, the operator starts the brake motor 8 via controller 2, driving the threaded rod 12 to rotate, causing the sliding frame 13 to move precisely along the axis within the second slot frame 15. Simultaneously, the first electric push rod 7 is manipulated to push the sliding block 9 to slide within the first slot frame 3, causing the entire assembly mechanism to move laterally and precisely align and position the two valve structures. During the assembly process, the controller 2 coordinates the linkage of each component to calibrate the positional deviation. After positioning is completed, the brake motor 8 is de-energized and self-locked to prevent component displacement. Subsequently, bolt tightening and other operations are performed. After assembly is completed, the controller 2 controls each push rod to reset, and the equipment returns to its initial state. This process, through the precise control of the controller 2, achieves the docking and positioning of valve components, effectively avoiding the misalignment problem of manual assembly and improving assembly accuracy and efficiency.
