Description

Technical Field

[0001] The utility model relates to the technical field of pipe winding, in particular to a pipe winding tool and a capillary pipe winding device formed by the tool. Background Art

[0002] As a regulating component for throttling and reducing pressure, the capillary tube needs to maintain a set length during the refrigerant circulation process of the air conditioner. However, due to the size limitation of the air conditioner, the capillary tube of a specific length needs to maintain a suitable installation size to facilitate the installation of the capillary tube in the air conditioner. Usually, the capillary tube needs to be designed to be wound so that its structure after winding meets the installation requirements of the air conditioner.

[0003] like Figure 1 As shown, a winding tube structure including two windings is shown, in which three parameters including the radii R1 and R2 of the two windings and the center distance L1 between the two windings are designed.

[0004] like Figure 2 As shown, a winding tube structure including three windings is shown, in which five parameters including the radius R1, R2 and R3 of the three windings and the center distance L1 and L2 between the two windings are designed. It should be noted that a one-way valve is provided between the two ends of the capillary tube after the winding, so the two ends of the capillary tube need to be in opposite directions after the winding, and the winding tube structure including three windings is a symmetrical structure.

[0005] When winding the capillary, parameters such as the winding, winding radius, and distance between different windings are designed. Since the lengths of capillaries vary greatly in different models, there are various sizes for the number of winding turns, winding radius, and center distance between windings. In the prior art, the winding tooling needs to correspond one-to-one to the winding structure. When one of the parameters changes, it is necessary to switch to another winding tooling for winding, which makes production switching time-consuming and labor-intensive. Utility Model Content

[0006] In order to overcome the problems existing in the related technology, one of the purposes of the utility model is to provide a pipe winding tool, which uses a first positioning sleeve and a second positioning sleeve that can slide to realize capillary winding of different structures, thereby realizing the unification of the pipe winding tool, avoiding frequent tool switching, and improving the pipe winding efficiency.

[0007] A pipe winding tool, comprising:

[0008] A first slide groove is provided with a first positioning sleeve that can slide along the first slide groove;

[0009] The second slide groove is provided with a second positioning sleeve capable of sliding along the second slide groove,

[0010] The extension directions of the first sliding groove and the second sliding groove do not overlap.

[0011] The present application has a simple structure, and the center distance can be adjusted according to actual needs, thereby improving the applicability of the pipe winding tooling, avoiding the frequent replacement of the pipe winding tooling in the prior art, and improving the pipe winding efficiency.

[0012] In a preferred technical solution of the present utility model, the first slide groove and the second slide groove are located in the same plane, and the extension direction of the first slide groove is perpendicular to the extension direction of the second slide groove.

[0013] The reason why the first slide groove and the second slide groove are arranged vertically in the present application is to facilitate the adjustment of the spacing between the first positioning sleeve and the second positioning sleeve. If the angle between the first slide groove and the second slide groove is less than 90 degrees, when adjusting the distance between the first positioning sleeve and the second positioning sleeve, the sliding distance of the first positioning sleeve and the second positioning sleeve needs to be larger, which also means that the length of the first slide groove and the second slide groove becomes larger, thereby making the size of the positioning plate larger, which is not conducive to the miniaturization design of the pipe winding tooling. The present application arranges the first slide groove and the second slide groove to be arranged vertically, which can make the length of the first slide groove and the second slide groove the shortest on the basis of satisfying the adjustment of the spacing between the two positioning sleeves, thereby making the size of the positioning plate smaller.

[0014] In a preferred technical solution of the present invention, the first slide groove and the second slide groove are located in the same plane, and the first slide groove and the second slide groove form an L-shaped slide groove, a T-shaped slide groove, or a cross-shaped slide groove.

[0015] In a preferred technical solution of the utility model, a first positioning column capable of sliding along the first sliding groove is provided in the first sliding groove, a first positioning sleeve is nested on the outer side of the first positioning column, and the first positioning sleeve is detachably connected to the first positioning column.

[0016] The present application designs the first positioning sleeve and the first positioning column as a detachable structure in order to facilitate the adjustment of the outer diameter of the first positioning sleeve so as to meet the needs of different winding tube structures. In view of the fact that the parameters of the winding tube structure include the coil radius and the center distance between the two coils, the coil radius can be adjusted by replacing the first positioning sleeve, and the center distance between the two coils can be adjusted by changing the position of the first positioning column in the first slide slot, thereby realizing the winding of different winding tube structures, improving the application scope of the winding tube tooling, and improving the winding efficiency.

[0017] In a preferred technical solution of the present utility model, the outer diameter of the first positioning sleeve is one of 25 mm, 30 mm, 35 mm, and 40 mm.

[0018] In a preferred technical solution of the utility model, the first slide groove is located in the positioning plate, an external thread is provided on the outer side of the first positioning column, an internal thread is provided in the first positioning sleeve, the first positioning column is arranged perpendicular to the first slide groove, and the two ends of the first positioning column are respectively connected to the positioning nut and the first positioning sleeve.

[0019] The present application realizes the fixation and loosening between the first positioning column and the first slide groove through the external thread of the first positioning column and the tightening and loosening relationship between the positioning nut and the internal thread of the first positioning sleeve, ensuring that the first positioning column can slide along the first slide groove during the position adjustment process and can be fixed relative to the first slide groove after the position is determined, which helps to improve the parameter adjustment of different winding tube structures.

[0020] In a preferred technical solution of the utility model, a second positioning column capable of sliding along the second sliding groove is provided in the second sliding groove, a second positioning sleeve is nested on the outer side of the second positioning column, and the second positioning sleeve is detachably connected to the second positioning column.

[0021] The second positioning sleeve and the second positioning column are designed as a detachable structure in this application in order to facilitate the adjustment of the outer diameter of the second positioning sleeve so as to meet the needs of different winding tube structures. In view of the fact that the parameters of the winding tube structure include the coil radius and the center distance between the two coils, the coil radius can be adjusted by replacing the second positioning sleeve, and the center distance between the two coils can be adjusted by changing the position of the second positioning column in the second slide slot, thereby realizing the winding of different winding tube structures, improving the application scope of the winding tube tooling, and improving the winding efficiency.

[0022] In a preferred technical solution of the utility model, the outer diameter of the second positioning sleeve is one of 25mm, 30mm, 35mm, and 40mm;

[0023] The second slide groove is located in the positioning plate, an outer side of the second positioning column is provided with an external thread, an inner thread is provided in the second positioning sleeve, the second positioning column is arranged perpendicular to the second slide groove, and both ends of the second positioning column are respectively connected to the positioning nut and the second positioning sleeve.

[0024] The present application realizes the fixation and loosening between the second positioning column and the second slide groove through the tightening and loosening relationship between the external thread of the second positioning column and the internal thread of the positioning nut and the second positioning sleeve, ensuring that the second positioning column can slide along the second slide groove during the position adjustment process and can be fixed relative to the second slide groove after the position is determined, which helps to improve the parameter adjustment of different winding tube structures.

[0025] In a preferred technical solution of the present invention, scale lines are arranged on the sides of the first slide groove and the second slide groove, and the scale lines are respectively distributed along the extension directions of the first slide groove and the second slide groove.

[0026] The scale lines provided in the present application can conveniently define the positions of the first positioning sleeve and the second positioning sleeve in the first slide groove and the second slide groove. After the position of the first positioning sleeve is fixed, the position of the second positioning sleeve can be conveniently calculated with the help of the scale lines, which can increase the moving speed of the second positioning sleeve, avoid using a ruler to continuously measure the distance between the first positioning sleeve and the second positioning sleeve, and increase the adjustment speed of the pipe winding tooling.

[0027] A capillary tube winding device comprises the tube winding tool as described above.

[0028] By using the capillary winding device provided in the present application to wind the capillary, the defect of frequently switching the winding device when the winding structure changes can be avoided, the applicability of the winding device can be improved, and the winding efficiency can be improved.

[0029] The second purpose of the utility model is to provide a capillary tube winding device, including the tube winding tool as described in the above item.

[0030] The beneficial effects of the utility model are:

When it is necessary to wind the pipe, the center distance between the two windings is determined, and the position of the first positioning sleeve in the first slide and the position of the second positioning sleeve in the second slide is changed, so that the distance between the first positioning sleeve and the second positioning sleeve is adjusted to the center distance between the two windings, and then the capillary and other pipes are wound between the first positioning sleeve and the second positioning sleeve in sequence, and the final pipe winding structure can be obtained. The structure of the present application is simple, and the center distance can be adjusted according to actual needs, which improves the applicability of the pipe winding tool, avoids the frequent replacement of the pipe winding tool in the prior art, and improves the pipe winding efficiency.

[0044] Example 1

[0045] The present application provides a pipe winding tool, comprising:

[0046] The first slide groove 13 is provided with a first positioning sleeve 14 that can slide along the first slide groove 13;

[0047] The second slide groove 21 is provided with a second positioning sleeve 22 which can slide along the second slide groove 21.

[0048] The extension directions of the first sliding groove 13 and the second sliding groove 21 do not overlap.

[0049] Since the first positioning sleeve 14 and the second positioning sleeve 22 can move along the first slide groove 13 and the second slide groove 21 respectively, the spacing between the first positioning sleeve 14 and the second positioning sleeve 22 is adjustable, and the adjustment of different coil center distance parameters can be achieved. In other words, the pipe winding tooling of the present application can achieve pipe winding structures with different center distances.

[0050] When it is necessary to wind the pipe, the center distance between the two windings is determined according to the final winding structure, and the distance between the first positioning sleeve 14 and the second positioning sleeve 22 is adjusted to the center distance between the two windings by changing the position of the first positioning sleeve 14 in the first slide groove 13 and the position of the second positioning sleeve 22 in the second slide groove 21, and then the pipes such as capillaries are wound between the first positioning sleeve 14 and the second positioning sleeve 22 in sequence to obtain the final winding structure. In the winding process, the number of turns of the pipe wound around the outside of the first positioning sleeve 14 and the number of turns of the pipe wound around the outside of the second positioning sleeve 2222 are both determined in advance.

[0051] For example, if the winding structure includes two turns, and needs to be wound 3.5 turns on the first positioning sleeve 14 and half a turn on the second positioning sleeve 22, the pipe can be firstly wound 3.5 turns on the outside of the first positioning sleeve 14, and then the pipe can be extended to the position of the second positioning sleeve 22 and wound half a turn. Since the positions of the first positioning sleeve 14 and the second positioning sleeve 22 are determined according to the distance between the two turns in the winding structure, after the winding of the first positioning sleeve 14 is completed, the pipe can be directly extended to the position of the second positioning sleeve 22 to meet the spacing between the two turns.

[0052] The present application has a simple structure, and the center distance can be adjusted according to actual needs, thereby improving the applicability of the pipe winding tooling, avoiding the frequent replacement of the pipe winding tooling in the prior art, and improving the pipe winding efficiency.

[0053] Example 2

[0054] like Figure 3 and Figure 4 As shown, a pipe winding tool provided in the present application includes a positioning plate 12, in which a first slide groove 13 and a second slide groove 21 are provided, and the extension directions of the first slide groove 13 and the second slide groove 21 do not overlap.

[0055] The first sliding groove 13 is provided with a first positioning sleeve 14 that can slide along the first sliding groove 13 ; the second sliding groove 21 is provided with a second positioning sleeve 22 that can slide along the second sliding groove 21 .

[0056] Specifically, in the present application, the positioning plate 12 is a planar plate-shaped structure, the first slide groove 13 and the second slide groove 21 arranged in the positioning plate 12 are located in the same plane, and the extension direction of the first slide groove 13 is perpendicular to the extension direction of the second slide groove 21 .

[0057] The reason why the first slide groove 13 and the second slide groove 21 are arranged vertically in the present application is to facilitate the adjustment of the spacing between the first positioning sleeve 14 and the second positioning sleeve 22. If the angle between the first slide groove 13 and the second slide groove 21 is less than 90 degrees, when adjusting the distance between the first positioning sleeve 14 and the second positioning sleeve 22, the sliding distance of the first positioning sleeve 14 and the second positioning sleeve 22 needs to be larger, which also means that the length of the first slide groove 13 and the second slide groove 21 becomes larger, thereby making the size of the positioning plate 12 larger, which is not conducive to the miniaturization design of the pipe winding tooling. The present application arranges the first slide groove 13 and the second slide groove 21 to be arranged vertically, which can make the length of the first slide groove 13 and the second slide groove 21 the shortest on the basis of satisfying the adjustment of the spacing between the two positioning sleeves, thereby making the size of the positioning plate 12 smaller.

[0058] like Figure 3As shown, the ends of the first slide groove 13 and the second slide groove 21 in the positioning plate 12 are connected to form an L-shaped structure. In order to facilitate the operator to perform the pipe winding operation, the present application can design the positioning plate 12 as a vertical plate, and specifically, the positioning plate 12 can be fixed in the pipe winding platform 11. When the pipe needs to be wound, the staff only needs to hold the pipe and wrap it in the first positioning sleeve 14 and the second positioning sleeve 22 in sequence according to the set number of turns.

[0059] In the present application, in addition to the adjustable spacing between the two coils, the outer diameters of the first positioning sleeve 14 and the second positioning sleeve 22 can also be adjusted, so as to meet the requirements of different coil radii.

[0060] Specifically, a first positioning column that can slide along the first sliding groove 13 is provided in the first sliding groove 13, and a first positioning sleeve 14 is embedded in the outer side of the first positioning column. The first positioning sleeve 14 is detachably connected to the first positioning column.

[0061] In the present application, the first positioning sleeve 14 and the first positioning column are detachably connected, and the first positioning column is always located in the first slide groove 13. There can be multiple first positioning sleeves 14, and they are respectively set to structures with different outer diameters. When the winding radius of the winding tube structure needs to be changed, the first positioning sleeve 14 can be removed and replaced with a first positioning sleeve 14 with a different outer diameter.

[0062] The first positioning sleeve 14 and the first positioning column are designed as detachable structures in this application in order to facilitate the adjustment of the outer diameter of the first positioning sleeve 14 so as to meet the needs of different winding tube structures. In view of the fact that the parameters of the winding tube structure include the winding radius and the center distance between the two windings, the adjustment of the winding radius can be achieved by replacing the first positioning sleeve 14, and the adjustment of the center distance between the two windings can be achieved by changing the position of the first positioning column in the first slide groove 13, thereby achieving the winding of different winding tube structures, improving the application range of the winding tube tooling, and improving the winding efficiency.

[0063] For example, four first positioning sleeves 14 can be designed, and the outer diameters of the four first positioning sleeves 14 are 25 mm, 30 mm, 35 mm, and 40 mm, respectively. These four sizes already include the common outer diameters of the winding coils, and the corresponding first positioning sleeves 14 can be selected according to the parameters of the winding tube structure and fixedly connected to the first positioning column.

[0064] In the present application, in addition to being able to slide in the first slide groove 13, once the position of the first positioning column is determined, it is also necessary to achieve the fixation of the first positioning column and the first slide groove 13. That is to say, in the process of adjusting the position of the first positioning column, the first positioning column can slide relative to the first slide groove 13. Once the position of the first positioning column is fixed, it is necessary to ensure that the position between the first positioning column and the first slide groove 13 is fixed, so as to avoid the sliding of the first positioning column during the pipe winding process, which causes the parameters of the pipe winding structure to change.

[0065] Specifically, in the present application, the first slide groove 13 is located in the positioning plate 12, an external thread is provided on the outer side of the first positioning column, an internal thread is provided in the first positioning sleeve 14, the first positioning column is arranged perpendicular to the first slide groove 13, and the two ends of the first positioning column are respectively connected to the positioning nut 15 and the first positioning sleeve 14.

[0066] Among them, the outer diameter of the positioning nut 15 is greater than the width of the first slide groove 13, the positioning nut 15 is fixed at one end of the positioning plate 12, and the other end of the first positioning column passes through the first slide groove 13 and extends perpendicular to the extension direction of the first slide groove 13. The outer side of the first positioning column is provided with an external thread, one end of the external thread is connected to the positioning nut 15, and the other end of the external thread is used to connect the internal thread inside the first positioning sleeve 14. The outer diameter of the first positioning column is smaller than the width of the first slide groove 13. When the first positioning column needs to slide along the first slide groove 13, the first positioning sleeve 14 is not installed on the first positioning column, or the first positioning sleeve 14 is installed on the first positioning column but does not abut against the positioning plate 12. At this time, there is a gap between the first positioning sleeve 14 and the positioning plate 12 or the positioning nut 15 and the positioning plate 12, and the first positioning column cannot be fixed in the positioning plate 12, that is, the first positioning column can slide along the first slide groove 13. When the position of the first positioning column in the first slide groove 13 is determined, tighten the first positioning sleeve 14 or the positioning nut 15 so that the first positioning sleeve 14 or the positioning nut 15 moves from both ends of the positioning plate 12 toward the positioning plate 12 until there is no gap between the positioning nut 15, the positioning plate 12 and the first positioning sleeve 14. At this time, the positioning nut 15 and the first positioning sleeve 14 respectively tighten the first positioning column from both ends of the first positioning column, thereby fixing the first positioning column in the positioning plate 12.

[0067] The present application realizes the fixation and loosening between the first positioning column and the first slide groove 13 through the external thread of the first positioning column and the tightening and loosening relationship between the positioning nut 15 and the internal thread of the first positioning sleeve 14, ensuring that the first positioning column can slide along the first slide groove 13 during the position adjustment process and can be fixed relative to the first slide groove 13 after the position is determined, which helps to improve the parameter adjustment of different winding tube structures.

[0068] Similarly, a second positioning column that can slide along the second sliding groove 21 is provided in the second sliding groove 21, and a second positioning sleeve 22 is embedded in the outer side of the second positioning column. The second positioning sleeve 22 is detachably connected to the second positioning column.

[0069] In the present application, the second positioning sleeve 22 and the second positioning column are detachably connected, and the second positioning column is always located in the second slide groove 21. The second positioning sleeve 22 can be multiple, and are respectively set to structures with different outer diameters. When the winding radius of the winding tube structure needs to be changed, the second positioning sleeve 22 can be removed and replaced with a second positioning sleeve 22 with a different outer diameter.

[0070] The second positioning sleeve 22 and the second positioning column are designed as a detachable structure in this application in order to facilitate the adjustment of the outer diameter of the second positioning sleeve 22 so as to meet the needs of different winding tube structures. In view of the fact that the parameters of the winding tube structure include the coil radius and the center distance between the two coils, the coil radius can be adjusted by replacing the second positioning sleeve 22, and the center distance between the two coils can be adjusted by changing the position of the second positioning column in the second slide groove 21, thereby realizing the winding of different winding tube structures, improving the application range of the winding tube tooling, and improving the winding efficiency.

[0071] For example, the second positioning sleeves 22 can be designed to be four, and the outer diameters of the four second positioning sleeves 22 are 25 mm, 30 mm, 35 mm, and 40 mm, respectively. These four sizes already include the common outer diameters of the winding coils, and the corresponding second positioning sleeves 22 can be selected according to the parameters of the winding tube structure and fixedly connected to the second positioning column.

[0072] In the present application, in addition to being able to slide in the second slide groove 21, once the position of the second positioning column is determined, it is also necessary to achieve the fixing of the second positioning column and the second slide groove 21. That is, in the process of adjusting the position of the second positioning column, the second positioning column can slide relative to the second slide groove 21. Once the position of the second positioning column is fixed, it is necessary to ensure that the position between the second positioning column and the second slide groove 21 is fixed, so as to avoid the sliding of the second positioning column during the pipe winding process, which causes the parameters of the pipe winding structure to change.

[0073] Specifically, in the present application, the second slide groove 21 is located in the positioning plate 12, an external thread is provided on the outer side of the second positioning column, an internal thread is provided in the second positioning sleeve 22, the second positioning column is arranged perpendicular to the second slide groove 21, and the two ends of the second positioning column are respectively connected to the positioning nut 15 and the second positioning sleeve 22.

[0074] Among them, the outer diameter of the positioning nut 15 is greater than the width of the second slide groove 21, the positioning nut 15 is fixed at one end of the positioning plate 12, and the other end of the second positioning column passes through the second slide groove 21 and extends perpendicular to the extension direction of the second slide groove 21. The outer side of the second positioning column is provided with an external thread, one end of the external thread is connected to the positioning nut 15, and the other end of the external thread is used to connect the internal thread inside the second positioning sleeve 22. The outer diameter of the second positioning column is smaller than the width of the second slide groove 21. When the second positioning column needs to slide along the second slide groove 21, the second positioning sleeve 22 is not installed on the second positioning column, or the second positioning sleeve 22 is installed on the second positioning column but does not abut against the positioning plate 12. At this time, there is a gap between the second positioning sleeve 22 and the positioning plate 12 or the positioning nut 15 and the positioning plate 12, and the second positioning column cannot be fixed in the positioning plate 12, that is, the second positioning column can slide along the second slide groove 21. When the position of the second positioning column in the second slide groove 21 is determined, tighten the second positioning sleeve 22 or the positioning nut 15 so that the second positioning sleeve 22 or the positioning nut 15 moves from both ends of the positioning plate 12 toward the positioning plate 12 until there is no gap between the positioning nut 15, the positioning plate 12 and the second positioning sleeve 22. At this time, the positioning nut 15 and the second positioning sleeve 22 respectively tighten the second positioning column from both ends of the second positioning column, thereby fixing the second positioning column in the positioning plate 12.

[0075] The present application realizes the fixation and loosening between the second positioning column and the second slide groove 21 through the tightening and loosening relationship between the external thread of the second positioning column and the internal thread of the positioning nut 15 and the second positioning sleeve 22, ensuring that the second positioning column can slide along the second slide groove 21 during the position adjustment process, and can be fixed relative to the second slide groove 21 after the position is determined, which helps to improve the parameter adjustment of different winding tube structures.

[0076] Furthermore, in the present application, scale lines are arranged on the sides of the first slide groove 13 and the second slide groove 21 , and the scale lines are respectively distributed along the extension directions of the first slide groove 13 and the second slide groove 21 .

[0077] The scale lines provided in the present application can conveniently define the positions of the first positioning sleeve 14 and the second positioning sleeve 22 in the first slide groove 13 and the second slide groove 21. After the position of the first positioning sleeve 14 is fixed, the position of the second positioning sleeve 22 can be conveniently calculated with the help of the scale lines, which can increase the moving speed of the second positioning sleeve 22, avoid using a ruler to continuously measure the distance between the first positioning sleeve 14 and the second positioning sleeve 22, and increase the adjustment speed of the pipe winding tooling.

[0079] The present application provides a pipe winding tool, which includes a positioning plate 12 , in which a first slide groove 13 and a second slide groove 21 are provided, and the extension directions of the first slide groove 13 and the second slide groove 21 do not overlap.

[0080] The first sliding groove 13 is provided with a first positioning sleeve 14 that can slide along the first sliding groove 13 ; the second sliding groove 21 is provided with a second positioning sleeve 22 that can slide along the second sliding groove 21 .

[0081] Specifically, in the present application, the positioning plate 12 is a planar plate-shaped structure, the first slide groove 13 and the second slide groove 21 arranged in the positioning plate 12 are located in the same plane, and the extension direction of the first slide groove 13 is perpendicular to the extension direction of the second slide groove 21 .

[0082] The difference from the second embodiment is that in this embodiment, the center points of the first slide groove 13 and the second slide groove 21 in the positioning plate 12 intersect to form a cross-shaped structure, such as Figure 5 shown.

[0083] In this structure, two or more first positioning columns can be set in the first slide groove 13, and two or more second positioning columns can be set in the second slide groove 21. A set of pipe winding devices is formed at the upper left part of the cross-shaped structure, and another set of pipe winding devices is formed at the lower right part of the cross-shaped structure. Two pipes can be wound at the same time to improve the pipe winding efficiency.

[0087] Specifically, in the present application, the positioning plate 12 is a planar plate-shaped structure, the first slide groove 13 and the second slide groove 21 arranged in the positioning plate 12 are located in the same plane, and the extension direction of the first slide groove 13 is perpendicular to the extension direction of the second slide groove 21 .

[0088] The difference from the second embodiment is that in this embodiment, the center point of the first slide groove 13 in the positioning plate 12 intersects with the end of the second slide groove 21 to form a T-shaped structure. Figure 6 shown.

[0089] In this structure, two or more first positioning columns can be set in the first slide groove 13, and two or more second positioning columns can be set in the second slide groove 21. A set of pipe winding devices is formed at the lower left part of the cross-shaped structure, and another set of pipe winding devices is formed at the lower right part of the cross-shaped structure. Two pipes can be wound at the same time to improve the pipe winding efficiency.

[0090] Example 5

[0091] The pipe winding tool in Example 2 is used to wind the Figure 1 When the winding tube structure is shown, first determine that the diameters of the two winding coils of the winding tube structure are both 25 mm, one of the winding coils is half a coil, the other winding coil is 3.5 coils, and the center distance between the two winding coils is 128 mm.

[0092] The specific winding method is:

[0093] A first positioning sleeve 14 with an outer diameter of 25 mm is selected and installed in the first positioning column;

[0094] Move the second positioning column in the second slide groove 21 to ensure that the distance between the first positioning column and the second positioning column is 128 mm; select a second positioning sleeve 22 with an outer diameter of 25 mm and install it in the second positioning column;

[0095] One end of the capillary is wound around the outside of the first positioning sleeve 14 for 3.5 turns, then extended to the outside of the second positioning sleeve 22, and then wound half a turn to complete the winding.

[0096] Example 6

[0097] The pipe winding tool in Example 2 is used to wind the Figure 2 When the winding tube structure is shown, first determine that the diameters of the two coils at both ends of the winding tube structure are 40 mm, the diameter of the middle coil is 30 mm, and the distances L1 and L2 from the middle coil to the coils at both ends are 77 mm.

[0098] The specific winding method is:

[0099] A first positioning sleeve 14 with an outer diameter of 40 mm is selected and installed in the first positioning column;

[0100] Move the second positioning column in the second slide groove 21 to ensure that the distance between the first positioning column and the second positioning column is 77 mm; select a second positioning sleeve 22 with an outer diameter of 30 mm and install it in the second positioning column;

[0101] One end of the capillary is wound around the outside of the first positioning sleeve 14 for a set number of turns, then extended to the outside of the second positioning sleeve 22, and then wound around the set number of turns;

[0102] The winding on the outer side of the first positioning sleeve 14 is removed and rotated 180°, and then the winding is continued to be wound around the first positioning sleeve 14 for a set number of turns to form a complete winding structure with symmetrical windings on both sides.

[0103] As another replaceable structure, the pipe winding tooling of the present application can also increase the number of slide grooves, and set corresponding positioning columns and positioning sleeves in the slide grooves, directly forming a linear structure of three positioning sleeves, which is directly used for winding a pipe winding structure with three coils.

[0104] It should be noted that when the winding pipe structure is a symmetrical structure, it can be completed with the help of two positioning sleeves. When the winding pipe structure is an asymmetrical structure, it can be achieved by adding a third slide groove and a corresponding third positioning sleeve. The third slide groove and the first slide groove 13 can be vertically arranged at the two ends of the second slide groove 21 respectively.

[0105] The present application also provides a capillary tube winding device, including the above-mentioned tube winding tooling. Using the capillary tube winding device provided by the present application to wind the capillary tube can avoid the defect of frequently switching the tube winding device when the tube winding structure changes, improve the applicability of the tube winding device, and improve the tube winding efficiency.
