Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber capillary wire arrangement, in particular to a glass fiber multi-capillary wire arrangement clamp. Background Art

[0002] In developing X-ray microbeam technology, standard borosilicate glass tubes are first stretched to the millimeter level on specialized equipment. These tubes are then tightly arranged and secured in a jig with a hexagonal cross-section. The tubes are then further stretched on a wire drawing machine and secured in a jig until the diameter of each tube is reduced to the micrometer level.

[0003] During this process, multiple thinned glass filaments are fixed in a capillary wire arrangement fixture system and repeatedly stretched and arranged until they meet the established standards. Given the requirements of the wire arrangement process, the design of the wire arrangement fixture must overcome several key technical challenges:

[0004] 1. The fixture needs to firmly fix the hexagonal cross-section cube structure composed of multiple capillaries while minimizing damage to the glass fiber capillaries;

[0005] 2. After the fixture body is installed on the special wire drawing equipment, the axis should be allowed to rotate to facilitate automatic centering adjustment. Once the adjustment is completed, the axial direction should have a locking function;

[0006] 3. The fixture should be easy to disassemble for reuse.

[0007] In the past, fixtures were typically cylindrical, with one end having a smaller diameter for securing to the three-jaw chuck of the wire drawing equipment. The other end had a larger diameter, hollowed out with a regular hexagonal cross-section. This could also be hollowed through to the smaller end. The two ends were connected by a threaded connection. Screw holes were punched into the outer wall of the larger end, lined with a thin iron sheet. After the glass tube to be drawn was inserted into the hexagonal hole, screws were used to press against the iron sheet inside, compressing the glass bundle. The tube was then heated and drawn.

[0008] However, this type of clamp poses a safety hazard during use. First, although the threaded connection between the shaft and the base allows both to rotate along the axis, there is no axial limit and there is a risk of falling off. Secondly, the use of screws to fix only achieves point contact, and the fixing effect is poor. Even if it is fixed through the iron sheet, it will cause uneven force on the iron sheet, which may cause the glass tube to break and be damaged. In fact, in the process of fixing it to the drawing device for heating and drawing, due to equipment tolerances and other reasons, the equipment may be slightly twisted during the elongation process, resulting in torsional asymmetry of the hexagonal side of the final product. Such a finished product cannot ensure that the outer wall of each glass tube is fully fitted during the next wire arrangement process, thus affecting the quality of the final product. Utility Model Content

[0009] The purpose of the present utility model is to provide a wire arranging fixture for glass fiber multi-capillaries. By adopting a split-assembled wire arranging fixing part and an automatic centering part, free rotation between the two without falling off is achieved. This design ensures that the wire drawing machine can be automatically adjusted during operation to prevent the product from twisting. In addition, the wire arranging fixing part adopts an opening and closing pressing mechanism of two components, which not only ensures that the inner wall side of the structure contacts the product when pressing the wire arrangement, thereby increasing the contact area to ensure uniform force, but also avoids the wire arrangement damage that may be caused by the point contact of traditional screw fixing.

[0010] To achieve the above object, the present utility model provides the following technical solutions:

[0011] A wire arranging fixture for glass fiber multi-capillaries, which is characterized in that: it includes a split-assembled wire arranging fixing part and an automatic centering part, and the two only have the freedom of relative concentric rotation; wherein: the wire arranging fixing part adopts an opening and closing pressing structure, and when it is pressed, a wire arranging fixing hole with a hexagonal cross-section can be formed; in the clamping state, the wire arranging fixing hole is in surface contact with the capillary wire arranging bundle.

[0012] Furthermore, the wire arranging fixing part includes an upper cover and a base, and the two can be connected by fixing screws. An upper notch is opened downward on the upper cover, and a lower notch is opened upward on the base; when the upper cover and the base are in a connected state, the upper notch and the notch together enclose the wire arranging fixing hole.

[0013] Furthermore, an upper docking platform is formed on the upper cover, and a through hole is opened on the upper docking platform; a lower docking table is formed on the base, and screw holes are opened on the lower docking table corresponding to the through holes one by one.

[0014] Furthermore, an installation ring is integrally formed at one end of the upper cover or the base. The automatic centering part includes a rotating shaft, and one section of the rotating shaft is assembled in the central hole of the installation ring through an anti-detachment structure.

[0015] Furthermore, a plurality of limiting holes are radially opened on the outer ring surface of the installation ring, and an annular limiting groove is opened on the section of the rotating shaft located in the central hole corresponding to the limiting holes; the anti-detachment structure includes a set screw, and the set screw extends into the limiting groove through the limiting hole to ensure that the rotating shaft can only rotate around its axis.

[0016] Furthermore, an adjusting hole is radially opened on the outer ring surface of the installation ring, and an adjusting screw is arranged in the adjusting hole, and the adjusting screw is used to abut against the rotating shaft to adjust the rotation damping of the rotating shaft.

[0017] Furthermore, both the fixing screw and the set screw are hexagon socket head cap screws, while the adjusting screw is a wing screw.

[0018] Furthermore, the height of the hexagonal cross-section of the wire arranging and fixing hole is 0.2 - 0.5 mm less than the height of the hexagonal cross-section of the capillary wire arranging bundle.

[0019] Compared with the prior art, the remarkable effects of the present utility model are as follows:

[0020] (1) By adopting a split-assembled wire arranging and fixing part and an automatic centering part, free rotation between the two without falling off is achieved. This design ensures that the wire drawing machine can be automatically adjusted during operation, preventing the product from twisting.

[0021] (2) The wire arranging and fixing part adopts an opening and closing pressing structure, and a hexagonal wire arranging and fixing hole is designed. This innovative design not only increases the contact area with the capillary wire arranging bundle but also makes the force more uniform. When pressing the wire arrangement, the inner wall side of the structure is in close contact with the product, effectively avoiding the problem of wire arrangement damage that may be caused by the point contact of traditional screw fixing. At the same time, the hexagonal cross-section design also improves the clamping stability and accuracy of the fixture.

[0022] (3) The upper cover and the base are connected by fixing screws, an upper docking platform and a through hole are provided on the upper cover, and a lower docking platform and a screw hole are provided on the base. These designs make the assembly and disassembly of the fixture more convenient and fast. At the same time, the anti-detachment structure design between the mounting ring and the rotating shaft also ensures the stability and reliability of the rotating shaft during rotation.

[0023] (4) The fixing screw, the set screw, and the adjusting screw all adopt easy-to-operate specifications and shapes (such as hexagon socket head cap screws and wing screws), enabling users to easily adjust and maintain during use. At the same time, the height of the hexagonal cross-section of the wire arranging and fixing hole is slightly less than the height of the hexagonal cross-section of the capillary wire arranging bundle. This design not only ensures the clamping stability but also avoids the clamping effects of being too tight or too loose. Description of the Drawings

Detailed implementation manner

[0033] In order to make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0034] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it should not be construed as a limitation to the present utility model. In addition, in the description of the present utility model, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0035] Figures 1 to 7The first embodiment of the present utility model is shown: A glass fiber multi-capillary wire arranging fixture includes a wire arranging fixing part and an automatic centering part that are assembled separately, and the two only have the freedom of relative concentric rotation; wherein: the wire arranging fixing part adopts an opening and closing pressing structure, and when it is pressed together, it can form a wire arranging fixing hole 1 with a hexagonal cross-section; in the clamping state, the wire arranging fixing hole 1 is in surface contact with the capillary wire arranging bundle.

[0036] As Figure 2 shown, in specific implementation, the wire arranging fixing part includes an upper cover 2 and a base 3, and the two can be connected by fixing screws 4. An upper notch 5 is opened downward on the upper cover 2, and a lower notch 6 is opened upward on the base 3; when the upper cover 2 and the base 3 are in a connected state, the upper notch 5 and the notch together enclose the wire arranging fixing hole 1. An upper docking platform is formed on the upper cover 2, and a through hole 7 is opened on the upper docking platform; a lower docking platform is formed on the base 3, and screw holes 8 are opened on the lower docking platform corresponding to the through holes 7 one by one.

[0037] In this embodiment, at least four through holes 7 are provided and are distributed at the four corners of the upper cover 2, and four screw holes 8 are also correspondingly provided and are distributed at the four corners of the base 3. The fixing screws 4 can pass through the through holes 7 and be threadedly connected with the corresponding screw holes 8 to realize the alignment and pressing of the upper cover 2 and the base 3, so as to ensure the stable clamping of the capillary wire arranging bundle and avoid damage to the capillary wire arranging bundle.

[0038] From Figure 1 and Figure 2 it can be seen that in actual use, an installation ring 9 is integrally formed at one end of the base 3, and the automatic centering part includes a rotating shaft 10. One section of the rotating shaft 10 is assembled in the central hole of the installation ring 9 through an anti-detachment structure. In some other embodiments, the installation ring 9 can also be integrally formed at the end of the upper cover 2. Preferably, in order to limit the freedom of the rotating shaft 10, a plurality of limiting holes 11 are radially opened on the outer ring surface of the installation ring 9, and a circular limiting groove 12 is opened on the section of the rotating shaft 10 located in the central hole corresponding to the limiting holes 11; the anti-detachment structure includes a set screw 13, and the set screw 13 extends into the limiting groove through the limiting hole 11 to ensure that the rotating shaft 10 can only rotate around its axis.

[0039] From Figures 1 to 3 it can be seen that in order to facilitate the user to adjust the rotation damping of the rotating shaft 10 to meet the wire drawing requirements, an adjustment hole 14 is also radially opened on the outer ring surface of the installation ring 9, and an adjustment screw 15 is arranged in the adjustment hole 14, and the adjustment screw 15 is used to abut against the rotating shaft 10 to adjust the rotation damping of the rotating shaft 10.

[0040] Specifically, both the fixing screw 4 and the set screw 13 are hexagon socket head cap screws, while the adjusting screw 15 is a wing screw. The height of the hexagonal cross-section of the wire arranging fixing hole 1 is 0.2 - 0.5 mm less than the height of the hexagonal cross-section of the capillary wire arranging bundle.

[0041] To more comprehensively understand the operating principle and its advantages of the present utility model, the above-mentioned embodiments will be further elaborated below, and discussions will be carried out in combination with possible actual application scenarios.

[0042] In the first embodiment, the design of the glass fiber multi-capillary wire arranging fixture not only takes into account the clamping stability, but also takes into account the flexibility and convenience of adjustment. In particular, the split opening and closing pressing structure adopted by the wire arranging fixing part forms a hexagonal wire arranging fixing hole 1 with precise dimensions through the combination of the upper cover 2 and the base 3. This design ensures that the capillary wire arranging bundle can maintain a stable shape during clamping and effectively avoid damage to the material.

[0043] In addition, the connection between the upper cover 2 and the base 3 adopts the method of threading the fixing screw 4 through the through hole 7 and the threaded hole 8. This connection method is not only simple and easy to implement, but also can ensure the firmness of the connection. At the same time, the number and positions of the through hole 7 and the threaded hole 8 are carefully considered, which not only ensures the connection stability, but also facilitates the user to install and disassemble the operation.

[0044] In the design of the automatic centering part, the present utility model cleverly utilizes the combination of the rotating shaft 10 and the mounting ring 9 to achieve the automatic centering function of the capillary wire arranging bundle. The rotating shaft 10 is fixed in the limiting hole 11 and the limiting groove of the mounting ring 9 through the set screw 13, ensuring that the rotating shaft 10 can only rotate around its axis, so that it can not only rotate adaptively during the wire drawing process, but also prevent the rotating shaft 10 from shifting, thereby achieving precise adjustment of the capillary wire arranging bundle. At the same time, the setting of the adjusting screw 15 provides the user with the convenience of adjusting the rotation damping of the rotating shaft 10, so that the user can accurately match the damping of the rotating shaft 10 according to the wire drawing requirements.

[0045] It should be noted that this embodiment is also very careful in detail processing. For example, both the fixing screw 4 and the set screw 13 are hexagon socket head cap screws. This design is not only convenient for the user to tighten the operation, but also can effectively prevent the screw from loosening. The adjusting screw 15 is a wing screw. This design is not only beautiful and generous, but also convenient for the user to quickly adjust without using tools.

[0046] In practical applications, the glass fiber multi-capillary wire arranging fixture of the present utility model can be widely applied to various occasions that require precise control of the morphology of the capillary wire arranging bundle. For example, in the glass fiber manufacturing industry, this fixture can be used for precise arrangement and fixation of the glass fiber wire bundle, thereby improving the product quality and production efficiency. In addition, in the fields of scientific research experiments, teaching demonstrations, etc., this fixture can also be used as an important auxiliary tool.

[0047] In summary, through its unique design and innovative structure, the glass fiber multi-capillary wire arranging fixture of the present utility model has successfully solved the problems and deficiencies existing in the prior art. It not only has the advantages of stable clamping, flexible adjustment, and simple operation, but also has high practical value and broad application prospects.
