Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for fiber winding process, specifically a positioning and guiding device for guiding fiber winding in composite gas storage cylinders. Background Technology

[0002] Composite gas cylinders, due to their advantages such as lightweight, high strength, corrosion resistance, and fatigue resistance, have been widely used in new energy vehicles, aerospace, and industrial gas storage and transportation. In their manufacturing process, fiber winding technology is a key process for achieving the structural performance of the cylinder. Traditional winding techniques typically rely on continuously laying fibers along a predetermined path on a smooth, regular cylinder surface, constructing a laminated structure that meets strength requirements through circumferential winding, helical winding, and polar winding. However, with the continuous expansion of composite gas cylinder applications in various scenarios, such as the emergence of complex and multifunctional products like water heater storage tanks, air-suspended gas cylinders, and brake gas cylinders, the cylinder surface often needs to integrate additional structures such as mounting brackets and waterproof valves, resulting in localized obstacles such as mounting posts and joints in the winding area.

[0003] During actual winding, yarns often slip, accumulate, or become suspended due to obstacles, disrupting the original stress transmission path and reducing the density between fiber layers and the consistency of mechanical properties. To address these issues, some technologies attempt to guide the flow by installing guide components in the obstacle area. However, these methods are limited by the fixing method of the guide components, such as the common threaded connection structure. Once the installation angle is determined, it is difficult to adjust, making it impossible to flexibly adapt to differences and changes in the obstacle's position. This results in limited flow guidance and makes it difficult to meet the quality requirements of complex bobbin winding.

[0004] Therefore, the existing technology lacks a flow guiding device that can flexibly adjust the flow direction according to the actual distribution of obstacles during the winding process and has stable positioning capabilities, so as to achieve the continuity and uniformity of the fiber winding path, improve the winding quality and the overall performance of the product. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a positioning and guiding device for guiding fiber winding in composite material gas storage cylinders, aiming to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A positioning and guiding device for guiding fiber winding in a composite material gas storage cylinder includes a diverter head body. A dividing plate is connected to the surface of the diverter head body, and a connecting post is provided on the surface of the diverter head body. A first positioning post is provided on the surface of the diverter head body, and a connecting threaded groove is formed at one end of the connecting post. A first through hole is formed on the surface of the dividing plate, and several first positioning holes and second positioning holes are respectively formed on the two ends of the dividing plate. A mounting base is connected to the surface of the dividing plate, and a second through hole is formed on the surface of the mounting base. A second positioning post and a mounting threaded post are respectively provided on the two ends of the mounting base. A third through hole is formed on the surface of the mounting threaded post, and a compression spring is provided inside the third through hole. A support block is connected to one end of the compression spring, and a connecting bolt is installed on the surface of the support block.

[0008] Furthermore, the connecting post, the first through hole, the second through hole, the third through hole, and the connecting bolt are all on the same axis, and the outer diameter of the connecting post is the same as the inner diameter of the first through hole and the second through hole.

[0009] Furthermore, the inner diameter of the connecting thread groove is the same as the outer diameter of the connecting bolt, and the connecting bolt is threaded inside the connecting thread groove.

[0010] Furthermore, the first positioning holes and the second positioning holes are distributed circumferentially along both ends of the indexing plate at equal intervals.

[0011] Furthermore, the first positioning hole and the second positioning hole provided on both sides of the indexing plate are offset from each other by 10 degrees in the circumferential direction.

[0012] Furthermore, the outer diameter of the first positioning post is the same as the inner diameter of the first positioning hole, and the outer diameter of the second positioning post is the same as the inner diameter of the second positioning hole.

[0013] Furthermore, the compression spring is sleeved on the outside of the connecting bolt, one end of the compression spring is connected to the surface of the support block, and the other end of the compression spring is connected to the surface of the mounting base.

[0014] This utility model provides a positioning and guiding device for guiding fiber winding in composite material gas storage cylinders, which has the following features:

[0015] Beneficial effects:

[0016] This invention, through the design of an adjustable-angle distributor head structure, combined with the first and second positioning holes at both ends of the indexing plate, and the first and second positioning posts, achieves two different angle adjustment methods. This solves the problem of fixed angles in traditional threaded installation methods, which cannot be flexibly adjusted according to winding requirements. Users can quickly adjust the angle of the distributor head and reliably position it according to the actual position of obstacles on the air tank, thereby guiding the yarn around local structures, achieving uniform distribution and stable laying of the yarn, effectively avoiding winding defects such as slippage, accumulation, and bridging, and improving fiber winding quality and the consistency and reliability of the air tank.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figures 1-4As shown in the figure, the present invention provides a positioning and guiding device for guiding fiber winding of composite material gas storage cylinder, including a diverter head body 1, an indexing plate 2 connected to the surface of the diverter head body 1, a connecting post 6 provided on the surface of the diverter head body 1, a first positioning post 13 provided on the surface of the diverter head body 1, a connecting thread groove 14 opened at one end of the connecting post 6, a first through hole 7 opened on the surface of the indexing plate 2, and a plurality of first positioning holes 9 and second positioning holes 15 respectively opened on the two ends of the indexing plate 2.

[0025] The indexing plate 2 is connected to the mounting base 3, and the mounting base 3 has a second through hole 8 on its surface. The two ends of the mounting base 3 are respectively provided with a second positioning post 10 and a mounting thread post 4. The outer diameter of the first positioning post 13 is the same as the inner diameter of the first positioning hole 9, and the outer diameter of the second positioning post 10 is the same as the inner diameter of the second positioning hole 15.

[0026] A third through hole is provided on the surface of the threaded post 4, and a compression spring 11 is installed inside the third through hole. The connecting post 6, the first through hole 7, the second through hole 8, the third through hole, and the connecting bolt 12 are all on the same axis. The outer diameter of the connecting post 6 is the same as the inner diameter of the first through hole 7 and the second through hole 8. The compression spring 11 is sleeved on the outside of the connecting bolt 12. One end of the compression spring 11 is connected to the surface of the support block 5, and the other end of the compression spring 11 is connected to the surface of the mounting base 3.

[0027] One end of the compression spring 11 is connected to a support block 5, and a connecting bolt 12 is installed on the surface of the support block 5. The inner diameter of the connecting thread groove 14 is the same as the outer diameter of the connecting bolt 12, and the connecting bolt 12 is threaded into the inside of the connecting thread groove 14.

[0028] The number of first positioning holes 9 and second positioning holes 15 is 18 each, and the first positioning holes 9 and the second positioning holes 15 are distributed circumferentially along both ends of the indexing plate at equal intervals. The first positioning holes 9 and the second positioning holes 15 on both sides of the indexing plate 2 are offset from each other by 10 degrees in the circumferential direction.

[0029] In one embodiment of this utility model, a positioning and guiding device for guiding fiber winding in a composite material air storage cylinder is installed by threading the mounting threaded post 4 to the composite material air storage cylinder connector, thus stably positioning the entire structure above the area to be wound in the air storage cylinder. This structure guides the fiber bundle winding path through the inclined surface of the diverter head body 1, solving problems such as yarn slippage, accumulation, and bridging caused by local protrusions such as mounting posts and waterproof valves on the cylinder surface, effectively improving the continuity and uniformity of fiber laying.

[0030] During the use of the device, when it is necessary to adjust the tilt direction of the diverter head body 1 to match the position of the obstacle, it can be adjusted in two ways. The first way is to simply pull up the diverter head body 1. At this time, since the diverter head body 1 is connected to the connecting bolt 12 through the connecting post 6, the pulling action will drive the connecting bolt 12 to move axially and overcome the tension of the compression spring 11, so that the first positioning post 13 disengages from the first positioning hole 9 on the indexing plate 2. The user can rotate the diverter head body 1 to the target angle and then release it. The compression spring 11 will reset and push the connecting post 6 back, so that the first positioning post 13 re-enters the other first positioning hole 9, thereby achieving angle locking.

[0031] The second method involves pulling up the entire structure of the diverter head body 1 and the indexing plate 2. This causes the connecting bolt 12 and the indexing plate 2 to move outward together, disengaging the second positioning pin 10 on the mounting base 3 from the second positioning hole 15 on the lower surface of the indexing plate 2. The user can rotate the diverter head body 1 and the indexing plate 2 to a new angular position. After release, the structure resets under spring force, and the second positioning pin 10 re-engages into the new second positioning hole 15 to complete the positioning. By providing two sets of first positioning holes 9 on the upper surface and second positioning holes 15 on the lower surface of the indexing plate 2, the device offers two angle adjustment methods to adapt to different usage needs, improving adjustment flexibility and operational convenience.

[0032] The two ends of the indexing plate 2 are respectively provided with a number of first positioning holes 9 and second positioning holes 15 at equal intervals along the circumference. The two sets of positioning holes are offset by 10 degrees in the circumference, thereby refining the angle adjustment resolution and making the two adjustment methods complementary, thus improving the accuracy and density of angle adjustment.

[0033] This structure is widely applicable to composite material air storage cylinders that experience local structural interference during the winding process, such as non-standard geometric containers in scenarios like water heaters, air suspension systems, and braking systems. By guiding the yarn, it smoothly bypasses obstacle areas, achieving a continuous, dense, and regular winding path, thereby significantly improving the winding quality, structural stability, and fatigue life of the product.

[0034] The positioning and guiding device provided by this utility model has a compact structure, is easy to install, has an adjustable angle, accurate positioning, and strong adaptability. It can not only meet the actual needs of complex winding scenarios in the current manufacturing of composite high-pressure vessels, but also provide important support for the improvement of the accuracy of subsequent automated winding systems. It has good engineering practicality and market application prospects.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
