Description

Technical Field

[0001] This application relates to the field of wire winding machine technology, and in particular to a device for manufacturing double-helix metal wire. Background Technology

[0002] Industrial X-ray inspection is increasingly used in production and daily life, leading to the widespread application of microfocus X-ray sources in these applications. The double-helix filament is the core component of a microfocus X-ray source.

[0003] Double-helix filaments are manufactured as follows: A "single-helix filament" is first made by winding a tungsten wire with a diameter less than 0.08 mm in a single spiral around a molybdenum wire with a diameter less than 0.15 mm. (See reference...) Figure 1A and Figure 1B As shown; then the "single spiral filament" is wound into a double spiral to finally create a "double spiral filament", see reference. Figure 2A and Figure 2B As shown.

[0004] refer to Figure 1A As shown, this single-helix filament can be formed, for example, by spirally winding a tungsten wire around a middle portion of a molybdenum wire. (Reference) Figure 2A As shown, the double-helix filament can be formed, for example, by spiraling the middle portion of a single-helix filament.

[0005] The details of a single winding of a miniature double-helix filament are indistinguishable to the naked eye and require microscopic observation due to their minute size. Most filament winding machines on the market are single-helix winding devices and cannot perform double-helix winding.

[0006] There is currently no effective solution to the technical problem that most existing wire winding machines are single-helix winding devices and cannot complete double-helix winding. Utility Model Content

[0007] This invention provides a double-helix metal wire manufacturing device, which at least solves the technical problem that most existing wire winding machines are single-helix winding equipment and cannot complete double-helix winding work.

[0008] According to one aspect of this application, a double-helix metal wire manufacturing apparatus is provided, comprising: a frame, a first spindle box and a second spindle box, a slide assembly, and a drive mechanism. The first and second spindle boxes are fixed to the frame, and a first spindle of the first spindle box and a second spindle of the second spindle box are arranged along the same axis for fixing a first metal wire along the axial direction. The slide assembly is movably mounted on the frame, and a first wire-feeding assembly and a second wire-feeding assembly are fixed on the slide assembly. The first and second wire-feeding assemblies are arranged on opposite sides of the axis and are used to supply metal wire in the axial direction. The drive mechanism is mounted on the frame and connected to the first spindle box, the second spindle box, and the slide assembly. During the manufacturing of the helical metal wire, it drives the first and second spindles to rotate synchronously, and simultaneously drives the slide assembly to move along the axial direction.

[0009] Therefore, according to the technical solution of this embodiment, the same equipment can be used to wind single-helix metal wires and process double-helix metal wires. Thus, double-helix filaments of microfocus X-ray sources can be prepared using only one piece of equipment, thereby solving the technical problem that most existing wire winding machines are single-helix winding equipment and cannot complete double-helix winding work.

[0027] Figures 3-6 This is a schematic diagram of the apparatus for manufacturing a double-helix metal wire according to this application. (Reference) Figures 3-6 As shown, this embodiment provides a double-helix metal wire manufacturing device, including: a frame 3, a first spindle box 2a and a second spindle box 2b, a slide assembly 4, and a drive mechanism. The first spindle box 2a and the second spindle box 2b are fixed to the frame 3, and the spindles 25a of the first spindle box 2a and 25b of the second spindle box 2b are arranged along the same axis for fixing a first metal wire 7 along the axial direction. The slide assembly 4 is movably mounted on the frame 3, and a first wire-feeding assembly 43 and a second wire-feeding assembly 44 are fixed on the slide assembly 4. The first wire-feeding assembly 43 and the second wire-feeding assembly 44 are arranged on both sides of the axis for supplying metal wire in the axial direction. The drive mechanism is mounted on the frame 3 and connected to the first spindle box 2a, the second spindle box 2b, and the slide assembly 4, for driving the spindles 25a and 25b of the first spindle box 2a and the second spindle box 2b to rotate synchronously, and simultaneously driving the slide assembly 4 to move along the axial direction.

[0028] As described in the background section, the details of a single winding of a miniature double-helix filament are indistinguishable to the naked eye and require microscopic observation due to its minute size. Most filament winding machines on the market are single-helix winding devices and cannot perform double-helix winding.

[0029] In view of this, this application provides an apparatus for manufacturing a double-helix metal wire. Thus, when manufacturing a double-helix metal wire, reference is made to... Figures 3-5As shown, firstly, the first metal wire 7 is fixed to the main shaft 25a of the first spindle box 2a and the main shaft 25b of the second spindle box 2b. This tightens the first metal wire 7 between the main shafts 25a and 25b. Then, the second metal wire 5 is deployed to the first and / or second wire-feeding assembly, with one end of the second metal wire 5 suspended from a pendant and the other end fixed to the first metal wire 7. Driven by the drive mechanism, the main shafts 25a and 25b of the first and second spindle boxes 2a and 2b rotate synchronously, thus driving the first metal wire 7 to rotate while simultaneously winding the second metal wire 5 around it. Simultaneously, the drive mechanism drives the slide assembly 4 to translate along the axial direction of the main shafts 25a and 25b (i.e., along the first metal wire 7), thereby adjusting the supply position of the second metal wire 5 during the winding process. In this way, the winding of the single-helix metal wire 8 is completed.

[0030] The single-helix metal wire 8 formed is shown in Figure 1. In this application, the single-helix metal wire 8 is a single-helix filament. It is made by winding a tungsten wire with a diameter of less than 0.08 mm as the second metal wire 5 in a single helix on a molybdenum wire with a diameter of less than 0.15 mm as the first metal wire 7.

[0031] Then, refer to Figure 6 As shown, a single-helix metal wire 8 is loaded onto the first spinning assembly 43 and the second spinning assembly 44. Then, a mandrel 9 for secondary spiraling is installed on the main shaft 25b of the second spindle box 2b, and the groove on the end face of the mandrel 9 is coupled to the single-helix metal wire 8. Then, the main shaft 25b of the second spindle box 2b is driven to rotate by a drive mechanism, simultaneously driving the slide plate assembly 4 to move, thereby completing the secondary spiraling of the single-helix metal wire 8, forming a spiral as shown in the diagram. Figure 2A The double-helix metal wire 10 is shown. In this application, the double-helix metal wire 10 may be, for example, a double-helix filament used in a microfocus X-ray source.

[0032] Therefore, according to the technical solution of this embodiment, the same equipment can be used to wind single-helix metal wires and process double-helix metal wires. Thus, double-helix filaments of microfocus X-ray sources can be prepared using only one piece of equipment, thereby solving the technical problem that most existing wire winding machines are single-helix winding equipment and cannot complete double-helix winding work.

[0033] Further, refer to Figures 3-5 As shown, during the first spiral process, the first wire-spinning assembly 43 or the second wire-spinning assembly 44 can be used to supply the second metal wire 5 in the axial direction, thereby spirally winding the second metal wire 5 onto the first metal wire 7. During the second spiral process, the first wire-spinning assembly 43 and the second wire-spinning assembly 44 can supply the single spiral metal wire 8 in the axial direction, thereby producing the double spiral metal wire 10.

[0034] Optionally, it also includes a mandrel 9, which can be detachably mounted to the second spindle 25b, and the end of the mandrel 9 is provided with a groove. See also... Figure 6 and Figure 7 As shown, when creating a double-helix wire 10 by secondary spiraling of a single-helix metal wire 8, the single-helix metal wire 8 is loaded onto the first spinning assembly 43 and the second spinning assembly 44. Then, the mandrel 9 is installed on the second spindle 25b, and the single-helix metal wire 8 is held in place by the groove on the end face of the mandrel 9. The second spindle 25b is then driven to rotate, which in turn drives the mandrel 9 to rotate, thus achieving double-helix winding. Finally, the extended portion is manually cut off, and the shape is adjusted to obtain the attached... Figure 2A The double-helix metal wire shown.

[0035] Optionally, the drive mechanism includes a main drive mechanism 1 and a feed mechanism 6. The main drive mechanism 1 drives the first spindle 25a and the second spindle 25b to rotate, and also drives the feed mechanism 6 to move the slide plate assembly 4. Thus, during operation, the slide plate assembly 4 is dragged by the feed mechanism 6 and slides on the frame 3, thereby precisely controlling the wire tension and maintaining stable wire spinning. The feed mechanism 6 accurately controls the wire spinning position, ensuring consistent pitch. This uniformly winds the first metal wire 5 onto the thicker metal wire 7, forming a single-helix metal wire 8.

[0036] Optionally, refer to Figure 8 As shown, the main transmission mechanism 1 includes: a handwheel 11, a first drive synchronous pulley 12a, a first main shaft synchronous belt 13a, a first support base 14, a transmission shaft 15, a first fixed base 16, a second main shaft synchronous belt 13b, a second drive synchronous pulley 12b, a feed synchronous belt 17, and a third drive synchronous pulley 18. The first support base 14 and the first fixed base 16 are connected and fixed to the frame 3. The handwheel 11 is connected to the transmission shaft 15. One end of the transmission shaft 15 is axially fixed to the first fixed base 16, and the other end is supported on the first support base 14. The first drive synchronous pulley 12a, the second drive synchronous pulley 12b, and the third drive synchronous pulley 18 are fixed to the transmission shaft 15 and rotate synchronously with the transmission shaft 15. The first drive synchronous pulley 12a is connected to the first main shaft 25a via the first main shaft synchronous belt 13a, driving the first main shaft 25a to rotate synchronously. The second active synchronous pulley 12b is connected to the second main shaft 25b via the second main shaft synchronous belt 13b, driving the second main shaft 25b to rotate synchronously. The third active synchronous pulley 18 is connected to the feed mechanism 6 via the feed synchronous belt 17, driving the feed mechanism 6 to move the slide plate assembly 4.

[0037] Therefore, during the operation of the device, the operator only needs to crank the handwheel 11 to rotate the drive shaft 15, which in turn drives the first drive synchronous pulley 12a, the second drive synchronous pulley 12b, and the third drive synchronous pulley 18. Then, the first drive synchronous pulley 12a can drive the first main shaft 25a to rotate via the first main shaft synchronous belt 13a, and the second drive synchronous pulley 12b can drive the first main shaft 25b to rotate via the second main shaft synchronous belt 13b, thereby driving the clamped first metal wire 7 to rotate, or driving the spindle 9 to rotate. Simultaneously, the third drive synchronous pulley 18 can drive the feed mechanism via the feed synchronous belt 17, moving the slide plate assembly 4.

[0038] In this way, the operator can simultaneously drive the first spindle box, the second spindle box, and the sliding plate assembly by turning the handwheel, thus facilitating operation. Furthermore, it allows for precise coordination between spindle rotation and the translation of the sliding plate assembly.

[0039] Optionally, refer to Figure 9 As shown, the feeding mechanism 6 includes: a second support base 61, a lead screw 62, a lead screw nut 63, a second fixed base 64, and a feeding timing pulley 65. The second support base 61 and the second fixed base 64 are connected and fixed to the frame 3. One end of the lead screw 62 is axially fixed on the second fixed base 64, and the other end is supported on the second support base 61. The feeding timing pulley 65 is fixed on the lead screw 62 and is connected to the third driving timing pulley 18 through the feeding timing belt 17. The lead screw nut 63 is fixedly connected to the slide plate assembly 4 and coupled to the lead screw 62.

[0040] In this way, the slide assembly 4 can be driven to move along the axial direction by rotating the lead screw 62 of the feed mechanism 6.

[0041] Furthermore, in this invention, the selected transmission ratios for the first winding and the second winding are different, requiring the complete replacement of the feed timing belt 17, the third driving timing pulley 18, and the feed timing pulley 65 to achieve the selected transmission ratio.

[0042] Optionally, refer to Figure 10A and Figure 10BAs shown, the first spindle box 2a includes: a first conical core 21a, a first positioning sleeve 22a, a first spindle timing pulley 23a, a first spindle box body 24a, a first spindle 25a, a first fixed plate 26a, and a first locking plate 27a. The first spindle 25a is rotatably mounted on the first spindle box body 24a, and a first through hole 251a extending along the axial direction is provided at the center of the first spindle 25a. The first spindle timing pulley 23a is fixed on the first spindle 25a and connected to the first driving timing pulley 12a via a first spindle timing belt 13a. The first fixed plate 26a is fixed to one end of the first spindle 25a, and the first locking plate 27a is pressed onto the first fixed plate 26a by locking screws to clamp the first metal wire 7. One end of the first positioning sleeve 22a is inserted into the first through hole 251a from the other end of the first spindle 25a, and a second through hole 221a for constraining the first metal wire 7 is provided. The other end of the first positioning sleeve 22a is provided with a first tapered hole 222a corresponding to the first tapered core 21a, and the first tapered hole 222a communicates with the second through hole 221a. The first tapered core 21a is inserted into the first tapered hole 222a, and a third through hole 211a corresponding to the second through hole 221a is provided at the center of the first tapered core 21a.

[0043] Therefore, when manufacturing the single-spiral metal wire, the first metal wire 7 can be passed through the first through hole 251a of the first spindle 25a. Then, the first conical core 21a first clamps the first metal wire 7 onto the first positioning sleeve 22a through its conical surface, and then the first locking disc 27a is pressed onto the first fixed disc 26a by the locking screw, thereby completing the working clamping of the first metal wire. In this way, the first metal wire 7 is securely clamped onto the first spindle 25a.

[0044] Compared with this invention, the existing wire winding device has a larger chuck structure, which cannot stably clamp the axis of small-diameter metal wires and cannot complete the operation of winding miniature single-helix filaments. This invention achieves the clamping of small-diameter metal wires (diameter less than 0.15mm), improves the support rigidity of metal wires with large aspect ratios (aspect ratio greater than 500), and enables precise winding of small-diameter metal wires (diameter less than 0.08mm) through the above structure.

[0045] Optionally, refer to Figure 11A and Figure 11BAs shown, the second spindle box 2b includes: a second conical core 21b, a second positioning sleeve 22b, a second spindle timing pulley 23b, a second spindle box body 24b, a second spindle 25b, a second fixed plate 26b, and a second locking plate 27b. The second spindle 25b is rotatably mounted on the second spindle box body 24b, and a fourth through hole 251b extending along the axial direction is provided at the center of the second spindle 25b. The second spindle timing pulley 23b is fixed to the second spindle 25b and connected to the second drive timing pulley 12b via a second spindle timing belt 13b. The second fixed plate 26b is fixed to one end of the second spindle 25b, and the second locking plate 27b is pressed onto the second fixed plate 26b by locking screws to clamp the first metal wire 7. One end of the second positioning sleeve 22b is inserted into the fourth through hole 251b from the other end of the second spindle 25b, and a fifth through hole 221b for constraining the first metal wire 7 is provided. The other end of the second positioning sleeve 22b is provided with a second conical hole 222b corresponding to the second conical core 21b, and the second conical hole 222b communicates with the fifth through hole 221b. The second conical core 21b is inserted into the second conical hole 222b, and a sixth through hole 211b corresponding to the fifth through hole 221b is provided at the center of the second conical core 21b.

[0046] Therefore, when manufacturing the single-spiral metal wire, the first metal wire 7 can be passed through the second through hole 251b of the second spindle 25b. Then, the second conical core 21b first presses the first metal wire 7 against the second positioning sleeve 22b through its conical surface to achieve initial clamping. Then, the second locking disc 27b is pressed against the second fixed disc 26b by the locking screw, thereby completing the working clamping of the first metal wire. In this way, the first metal wire 7 is securely clamped on the second spindle 25b.

[0047] Optionally, refer to Figure 12 As shown, the slide block assembly 4 includes: a slide block 41, a wire nut seat 42, a first wire feeding assembly 43, a second wire feeding assembly 44, and a center frame 45. The slide block 41 is movably mounted on the frame 3 and can translate along the axial direction; the wire nut seat 42 is fixedly connected to the wire nut 63; the first wire feeding assembly 43 and the second wire feeding assembly 44 are fixedly mounted on the slide block 41 and positioned on opposite sides of the axial direction, with the first wire feeding assembly 43 being closer to the first spindle box 2a than the second wire feeding assembly 44; the center frame 45 is mounted on the slide block 41 at a position corresponding to the axial direction, and the center frame 45 has a groove corresponding to the axial direction.

[0048] refer to Figure 3-5 As shown, during one winding process, the second metal wire 5 can be fed by attaching one end of the second metal wire 5 to the hammer Z and loading the other end onto the first metal wire 7 via a pulley and a wire-feeding assembly. Furthermore, the center frame 45 can further stabilize the first metal wire 7.

[0049] In addition, see reference Figure 6 and Figure 12 As shown, during the secondary winding process, the two ends of the single spiral metal wire 8 can be hung with the hanging weights Z respectively, thereby loading them onto the two wire-spinning assemblies.

[0050] In this way, a single spiral operation and a double spiral operation can be achieved through the sliding component 4, thereby producing a double spiral wire 10.

[0051] Optionally, the first spinning assembly 43 includes a first pulley 431 and a first spinning frame 432, wherein the first spinning frame 432 extends between the first pulley 431 and the axis and is provided with a thread groove corresponding to the first pulley 431; and the second spinning assembly 44 includes a second pulley 441 and a second spinning frame 442, wherein the second spinning frame 442 extends between the second pulley 441 and the axis and is provided with a thread groove corresponding to the second pulley 441.

[0052] Thus, the supply of the second metal wire or the single spiral metal wire can be achieved more smoothly through the pulleys and the wire feeding frame, and the stretching direction of the second metal wire or the single spiral metal wire can be smoothly changed.

[0053] Optionally, the side of the first spinning assembly 43 and the second spinning assembly 44 that is closer to the axis is closer to the first spindle box 2a than the side that is farther away from the axis.

[0054] Thus, this utility model achieves the following technical effects:

[0055] 1. The synchronous dual-spindle structure greatly improves the rotational rigidity of molybdenum wires with small diameter (diameter less than 0.15mm) and large length-to-diameter ratio (length-to-diameter ratio greater than 500).

[0056] 2. The structure of the wire feeder being close to the rotating molybdenum wire greatly reduces the bending deformation of the molybdenum wire.

[0057] 3. The combination of the positioning sleeve and the conical core enables the centering and initial clamping of small-diameter (less than 0.15mm) metal wires; the combination of the locking disc and the fixing disc enables its working clamping. Distributing the required centering and clamping functions to different components not only solves the problem of clamping small-diameter (less than 0.15mm) metal wires, but also reduces the manufacturing difficulty of parts and compresses the volume of structural components.

[0058] 4. A double-spinning frame structure with two front and rear spinning frames allows one machine to complete both single-helix and double-helix spinning.

[0059] 5. The tension of the metal wire is controlled by the gravity of the plumb bob, resulting in accurate and stable tension control.

[0060] Therefore, compared with existing wire winding machines, this invention has the following advantages:

[0061] 1) Compact size, 300mm long * 150mm high * 200mm deep, suitable for the production of miniature filaments.

[0062] 2) The combination fixture can achieve centering and clamping of metal wires with a diameter of less than 0.2mm.

[0063] 3) One machine can complete both single-helix winding and double-helix winding.

[0064] 4) The tension of the metal wire is accurately and stably controlled during winding.
