Description

Technical Field

[0001] This application relates to the field of wire harness processing, and in particular to a punching and braiding mechanism. Background Technology

[0002] Currently, braided wires are widely used in various fields of modern manufacturing due to their high strength, flexibility, and aesthetics, such as electronics, automotive, aerospace, and everyday consumer goods. As market demand for braided wire products continues to grow, the requirements for their production efficiency, precision, and quality are also increasing. Many braided wire products need to be cut to specific lengths during the production process to meet the needs of different application scenarios. For example, in the electronics industry, braided wires are often used as components of internal connecting wires or cables, and the lengths of these connecting wires or cables must be precisely controlled to ensure they can be correctly installed in equipment.

[0003] The related technology wire harness braiding and cutting assembly includes a frame and a punching assembly. A cutting cavity is formed within the frame. The frame has a first panel facing the wire harness, and a feeding channel is provided on the first panel. The feeding channel divides the first panel into a first baffle and a second baffle. The wire harness passes through the feeding channel and enters the cutting cavity, where the braid contacts and adheres to the inner surface of the first panel. The punching assembly includes a first punching member and a second punching member, which are movably mounted within the cutting cavity. The first punching member is positioned opposite the first baffle, and the second punching member is positioned opposite the second baffle. When the braid contacts and adheres to the inner surface of the first baffle, the first punching member punches towards the first baffle to cut the braid. When the braid contacts and adheres to the inner surface of the second baffle, the second punching member punches forward to cut the remaining braid. The frame is composed of six panels, forming a cutting cavity within the frame. Two panels, positioned opposite each other, are designated as the first panel and the second panel. The first panel has a feed channel running vertically through it, dividing it into a first baffle and a second baffle. The width of the feed channel is greater than the diameter of the longest weave. The cutting cavity contains a first punch and a second punch that can move back and forth. The first punch is positioned opposite the first baffle, and the second punch is positioned opposite the second baffle. The first punch is used to cut half of the weave, and the second punch is used to cut the other half, thus completing the circumferential cutting of the entire weave.

[0004] The related wire harness braiding and cutting assembly has a frame enclosed by six panels, forming a fixed cutting cavity inside. The first panel has a feeding channel divided into first and second baffles. Inside the cutting cavity, first and second punching components, which can move back and forth, are positioned opposite the two baffles, achieving circumferential cutting of the braid through step-by-step punching. However, during the punching and braiding process, the frame and cutting cavity structure are fixed, and the step-by-step punching method for circumferential cutting makes it difficult to flexibly adapt to the cutting needs of various wire types. For different specifications of wire, there may be problems such as inconvenient adjustment of the cutting position and poor equipment versatility, making it impossible to efficiently and conveniently complete the cutting operation of braids of various wire types. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a punching and weaving mechanism.

[0006] The punching and weaving mechanism provided in this application adopts the following technical solution:

[0007] A punching and braiding mechanism includes a base, a wire clamping mechanism, a moving mechanism, a clamping mechanism, and a braiding and cutting mechanism. The base provides a support platform. The wire clamping mechanism is mounted on the base and is used to clamp and fix the wire to be processed. The moving mechanism is mounted on the base and is used to adjust the position of the braiding and cutting mechanism according to different types of wire. The clamping mechanism is mounted on the moving mechanism and is used to clamp and fix the wire. The braiding and cutting mechanism is mounted on the moving mechanism and is used to cut the braided wire to a standard length.

[0008] By adopting the above technical solution, the punching and braiding mechanism of this application provides a support platform through the base, the wire clamping mechanism clamps and fixes the wire to be processed, the moving mechanism can adjust the position of the braiding and cutting mechanism according to different types of wire, the clamping mechanism further clamps and fixes the wire, and the braiding and cutting mechanism cuts the braided wire to a standard length, so that the device can flexibly adjust the cutting position according to different types of wire, effectively solving the problems of poor equipment versatility and inconvenient cutting position adjustment in related technologies, and can efficiently and conveniently complete the cutting operation of braiding various types of wire.

[0009] Optionally, the moving mechanism specifically includes a sliding seat and a first cylinder; the sliding seat slides with the base, the support is fixed on the base, the cylinder body of the first cylinder is fixed on the base, the extended end of the piston rod of the first cylinder is fixedly connected to the sliding seat, and the first cylinder is used to drive the sliding seat to move in the horizontal direction.

[0010] By adopting the above technical solution, the moving mechanism is configured with a sliding seat that slides into the base. A first cylinder, fixed to the base, has its piston rod extended end fixedly connected to the sliding seat, allowing the first cylinder to drive the sliding seat to move horizontally during operation. This enables the braiding and cutting mechanism to move horizontally along with the sliding seat, allowing for flexible and precise adjustment of the cutting position according to different wire types. This effectively improves the device's adaptability to different wire specifications and enhances the convenience and efficiency of the cutting operation.

[0011] Optionally, the clamping mechanism includes a lifting component and a clamping component; the lifting component is disposed on the base, the lifting component is used to drive the clamping component to move up and down, and the clamping component is used to clamp the wire.

[0012] By adopting the above technical solution, the lifting component is mounted on the base and used to drive the clamping component to move up and down, while the clamping component is responsible for clamping the wire. This allows the clamping mechanism to flexibly adjust the height of the clamping component according to the position of the wire or the cutting requirements, thereby ensuring the stability and accuracy of the wire during the cutting process and improving the adaptability of the device to different cutting scenarios and the cutting quality.

[0013] Optionally, the lifting assembly includes a support seat, a lifting seat, and a first lifting cylinder; the support seat is fixed to the base, the bottom end of the first lifting cylinder is fixedly connected to the upper surface of the support seat, and the piston rod of the first lifting cylinder is fixedly connected to the lifting seat for driving the lifting seat to move up and down.

[0014] By adopting the above technical solution, the bearing seat is firmly fixed on the base, providing basic support for the entire lifting assembly. The bottom end of the first lifting cylinder is fixedly connected to the upper surface of the bearing seat, and its piston rod is connected to the lifting seat. Through the extension and retraction of the cylinder piston rod, the lifting seat can be driven to perform lifting operations, so that the clamping assembly can be lifted and lowered together with the lifting seat. This allows for flexible adjustment of the clamping height according to the actual situation of the wire or cutting requirements, ensuring stable clamping of the wire during the cutting process and effectively improving the adaptability and cutting accuracy of the device.

[0015] Optionally, the clamping assembly includes a linkage component, a second lifting cylinder, a first moving component, a second moving component, a linkage rod, a first clamping component, and a second clamping component. The linkage component includes a lifting block, and the lifting seat has a lifting groove and a sliding groove that communicate with each other. The lifting block slides in conjunction with the lifting groove. The second lifting cylinder is fixed to the lifting seat, and the piston rod of the second lifting cylinder is fixedly connected to the lifting block. The first moving component slides in conjunction with the sliding groove, and the second moving component slides in conjunction with the sliding groove. The linkage rod is fixedly connected to the lifting block. The side wall of the first moving component has a first arc-shaped groove, and the side wall of the second moving component has a second arc-shaped groove. One end of the linkage rod passes through the first arc-shaped groove and slides in conjunction with it, and the other end of the linkage rod passes through the second arc-shaped groove and slides in conjunction with it. The first clamping component is fixed to the first moving component, and the second clamping component is fixed to the second moving component. The first clamping component and the second clamping component are used to clamp the wire.

[0016] By adopting the above technical solution, the lifting block slides and engages within the lifting groove of the lifting seat, the second lifting cylinder drives the lifting seat to rise and fall, the first and second moving parts slide within the sliding groove at the bottom of the lifting seat, and the linkage rod passes through the lifting block and is fixed thereto, realizing the linkage between the first and second moving parts. The first and second clamping parts are respectively fixed to the lower surfaces of the first and second moving parts for clamping wires. This allows the clamping assembly to not only rise and fall with the lifting seat as a whole to adjust its height, but also to move the first and second moving parts synchronously through the linkage rod, thereby driving the first and second clamping parts to flexibly adjust their clamping positions, thus efficiently and accurately clamping wires of different specifications and positions, improving the flexibility of the device and the efficiency and quality of the cutting operation.

[0017] Optionally, the braiding and cutting mechanism includes a sliding rod, a first cutting cylinder, a second cutting cylinder, and a second cylinder; a sliding hole is provided on the support seat, the sliding rod slides into the sliding hole, and the piston rod of the second cylinder is fixedly connected to the end of the sliding rod for driving the sliding rod to move; the first cutting cylinder and the second cutting cylinder are respectively disposed on the sliding rod and the wire clamping assembly for cutting the wire; a cutting hole is provided at the end of the first cutting cylinder, the diameter of which is smaller than the outer diameter of the second cutting cylinder; a cutting chamfer is provided at the end of the second cutting cylinder facing the first cutting cylinder, and when the first cutting cylinder moves toward the direction close to the second cutting cylinder, the annular edge of the end of the first cutting cylinder tightly abuts against the surface of the cutting chamfer, and the first cutting cylinder and the second cutting cylinder cooperate to realize the circumferential cutting of the wire.

[0018] By adopting the above technical solution, the sliding rod slides and engages with the sliding hole on the support seat, and the sliding rod is driven to move by the second cylinder, so that the first cutting cylinder set on the sliding rod can move toward the second cutting cylinder set on the wire clamping assembly. The diameter of the cutting hole at the end of the first cutting cylinder is smaller than the outer diameter of the second cutting cylinder, and the end of the second cutting cylinder facing the first cutting cylinder is provided with a cutting chamfer. When the first cutting cylinder moves toward the second cutting cylinder, its end ring-shaped edge tightly abuts against the cutting chamfer surface. The first cutting cylinder and the second cutting cylinder can work closely together to accurately and efficiently realize the circumferential cutting of the wire, ensure the cutting quality, and at the same time improve the adaptability and flexibility of the device to different wire cutting operations.

[0019] Optionally, the second cutting tube includes a first half-tube and a second half-tube; the first half-tube is fixed to the first clamping member, and the second half-tube is fixed to the second clamping member; the first half-tube and the second half-tube are respectively provided with a semi-circular first through hole and a second through hole, and when the first half-tube and the second half-tube abut together, the first through hole and the second through hole combine to form a through-hole, through which the wire can pass.

[0020] By adopting the above technical solution, the first half-tube is fixed on the first clamping member, and the second half-tube is fixed on the second clamping member. The movement of the clamping components realizes the contact and separation of the first half-tube and the second half-tube. When the two half-tubes contact each other, the semi-circular first through hole and the second through hole opened on them respectively combine to form a through-hole, allowing the wire to pass through smoothly. This not only facilitates the threading and positioning of the wire, but also, during cutting, the first cutting tube and the combined second cutting tube (first and second half-tubes) cooperate to achieve circumferential cutting, which not only ensures the accuracy and efficiency of cutting, but also makes the entire cutting process more flexible and controllable, effectively improving the adaptability of the device to cutting wires of different specifications and the convenience of operation.

[0021] Optionally, the end of the first clamping member is provided with a first positioning groove for limiting the wire, and the end of the second clamping member is provided with a second positioning groove for limiting the wire.

[0022] By adopting the above technical solution, when the first clamping member and the second clamping member cooperate to clamp the wire, the wire can be accurately limited within the space formed by the first positioning groove and the second positioning groove, which effectively enhances the stability of the wire during the cutting process, prevents the wire from shifting or shaking during cutting, thereby ensuring the accuracy of the cutting position and improving the cutting quality. At the same time, it also enables the device to better maintain cutting accuracy and stability when processing wires of different specifications, enhancing the reliability and applicability of the device.

[0023] Optionally, one end of the first movable member is integrally formed with a second guide block, and the second movable member has a first guide groove on its side wall facing the first movable member. The first guide groove extends along a first direction, and both ends of the first guide groove are open. The second guide block is located in the first guide groove, and the second guide block slides and engages with the first guide groove.

[0024] By adopting the above technical solution, a second guide block is integrally formed at one end of the first moving part, and a first guide groove extending in the first direction and open at both ends is opened on the side wall of the second moving part facing the first moving part. The second guide block is located in the first guide groove and slides with it, providing precise guidance for the relative movement of the first and second moving parts. This ensures that the two maintain the correct relative position and movement trajectory during the movement, avoiding problems such as unstable clamping or inaccurate cutting caused by movement deviation. This effectively improves the accuracy and reliability of the clamping component's action, thereby enhancing the working performance and cutting quality of the entire punching and weaving mechanism.

[0025] Optionally, a hopper is fixedly installed on the sliding seat, the top and bottom of the hopper are both open, and the hopper is located directly below the weaving and cutting mechanism; a waste box is also fixedly installed on the upper surface of the base, and the waste box is located below the hopper.

[0026] By adopting the above technical solution, a hopper with openings at both the top and bottom is fixedly installed on the sliding seat and positioned directly below the weaving and cutting mechanism. Waste generated during the cutting process can fall directly into the hopper, while a waste box fixedly installed on the upper surface of the base is located below the hopper and can receive the waste falling from the hopper. This achieves centralized collection of waste, avoids the mess and cleaning difficulties caused by scattered waste, not only helps to keep the work area clean and improve work efficiency, but also facilitates the unified treatment of waste in the future.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By setting up a moving mechanism, the braiding and cutting mechanism can flexibly adjust its position according to different types of wires, which solves the problems of poor equipment versatility and inconvenient adjustment of cutting position in related technologies. It can efficiently and conveniently complete the cutting operation of braiding various types of wires, and improve the adaptability of the device to different specifications of wires and the convenience and efficiency of the cutting operation.

[0029] 2. Through the coordinated work of the lifting component and the clamping component, the clamping mechanism not only realizes the flexible adjustment of the height of the clamping component, but also enables the first and second moving parts to move synchronously through the linkage rod, so as to drive the first and second clamping parts to accurately clamp wires of different specifications and positions. At the same time, the positioning grooves at the ends of the first and second clamping parts further enhance the stability of the wires during the cutting process, prevent the wires from shifting or shaking, ensure the accuracy of the cutting position, and improve the cutting quality.

[0030] 3. A hopper is installed on the sliding seat and positioned directly below the weaving and cutting mechanism. Waste generated during the cutting process can fall directly into the hopper and be collected by the waste box located below the hopper. This achieves centralized collection of waste, avoids the mess and cleaning difficulties caused by scattered waste, helps maintain the cleanliness of the work area, improves work efficiency, and facilitates the unified treatment of waste in the future.

Detailed Implementation

[0039] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0040] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Unless otherwise defined, the technical or scientific terms used in this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0041] For ease of understanding, in this embodiment, the length direction of the wire is defined as the first direction in the horizontal direction, and the direction perpendicular to the first direction is defined as the second direction. The punching and braiding equipment is described based on this.

[0042] This application discloses a punching and weaving mechanism. (Refer to...) Figure 1 The punching and braiding equipment includes a base 1, a wire clamping mechanism 2, a moving mechanism 3, a holding mechanism, and a braiding and cutting mechanism 6. The wire clamping mechanism 2 is mounted on the base 1 and is used to clamp and fix the wire to be processed. The moving mechanism 3 is mounted on the base 1 and adjusts the position of the cutting mechanism along a first direction according to different wire types. The clamping mechanism is used to simultaneously clamp and fix multiple wires, and the cutting mechanism is used to cut the braided wire to a standard length.

[0043] Reference Figure 1The base 1 includes a base plate 11, a top plate 12, and two support plates 13. The two support plates 13 are parallel to each other. The bottom end of each support plate 13 is fixedly connected to the upper surface of the base plate 11, and the top end of each support plate 13 is fixedly connected to the lower surface of the top plate 12. By setting two parallel support plates 13, the base 1 securely connects the base plate 11 and the top plate 12, forming a stable support structure, which provides a reliable mounting platform for the wire clamping mechanism 2, the moving mechanism 3, the clamping mechanism, and the weaving and cutting mechanism 6.

[0044] Reference Figure 1 and Figure 2 The moving mechanism 3 includes a sliding seat 31, a support 32, and a first cylinder 33. The sliding seat 31 is slidably engaged with the top plate 12. The support 32 is fixed to the top plate 12, and the first cylinder 33 is fixed to the support 32. The piston rod of the first cylinder 33 is fixedly connected to the end of the sliding seat 31. When different types of wire need to be processed, the piston rod is driven to extend and retract by the first cylinder 33, which facilitates the movement of the sliding seat 31 along the second direction. This facilitates the simultaneous movement of the clamping mechanism and the braiding and cutting mechanism 6 along the second direction, thereby enabling the cutting of braids of various types of wire. Of course, the first cylinder 33 can also be an electric push rod. Electric push rods have the characteristics of smooth operation and high precision, and can more accurately control the moving distance and speed of the sliding seat 31, which has obvious advantages in situations where high positional accuracy is required.

[0045] Reference Figure 2 A slider 35 is fixedly provided on the lower surface of the sliding seat 31, and a guide rail 15 is fixedly provided on the upper surface of the base 1. The guide rail 15 extends along the first direction and passes through the slider 35. The slider 35 and the guide rail 15 slide together, which increases the stability of the sliding seat 31 moving along the first direction.

[0046] Reference Figure 1 In this embodiment, there are two clamping mechanisms, both of which are mounted on the sliding base 31 and are arranged at intervals along the first direction. Each clamping mechanism includes a lifting component 4 and a clamping component 5. The lifting component 4 is mounted on the base 1 and is used to drive the clamping component 5 to move up and down.

[0047] Continue to refer to Figure 1Furthermore, the lifting assembly 4 includes a lifting seat 41, a support seat 42, and a first lifting cylinder 43 for the lifting seat. The support seat 42 is fixed to the upper surface of the top plate 12, the bottom end of the first lifting cylinder 43 is fixedly connected to the upper surface of the support seat 42, and the piston rod of the first lifting cylinder 43 is fixedly connected to the lifting seat 41. The first lifting cylinder 43 is used to drive the lifting seat 41 to rise and fall. The clamping assembly 5 is disposed on the lifting seat 41. When it is necessary to adjust the height of the clamping assembly 5, the first lifting cylinder 43 starts to work, and its piston rod extends and retracts to drive the lifting seat 41 to rise and fall. Since the clamping assembly 5 is disposed on the lifting seat 41, the height of the clamping assembly 5 is automatically adjusted to adapt to the processing position of different wires.

[0048] Continue to refer to Figure 1 A guide seat 44 is fixedly provided on the upper surface of the support seat 42. A second guide groove 45 is provided at the top of the guide seat 44 and extends vertically. A first guide block 46 is fixedly provided on the lower surface of the lifting seat 41 and extends vertically. The bottom end of the first guide block 46 is inserted into the second guide groove 45. The first guide block 46 slides and engages with the second guide groove 45, which increases the stability of the lifting seat 41 and the clamping assembly 5.

[0049] Reference Figure 1 , Figure 3 and Figure 4 The clamping assembly 5 includes a linkage 51, a second lifting cylinder 52, a first moving member 53, a second moving member 54, a first clamping member 55, and a second clamping member 56. The lifting seat 41 has a lifting groove 47 at its top and a sliding groove 48 at its bottom, extending along a first direction. Both ends of the sliding groove 48 are open, and the bottom of the lifting groove 47 communicates with the sliding groove 48. The linkage 51 includes a lifting block 511 located within the lifting groove 47, slidingly engaging with it. The second lifting cylinder 52 is fixed to the outer wall of the lifting seat 41, and its piston rod is fixedly connected to the lifting seat 41. The second lifting cylinder 52 drives the lifting block 511 to rise and fall. The first moving part 53 and the second moving part 54 are both located in the sliding groove 48. The first moving part 53 and the second moving part 54 are both slidingly engaged with the sliding groove 48. The machining accuracy of the sliding groove 48 is IT7 grade. The clearance between the moving part and the sliding groove 48 is controlled between 0.02-0.05mm.

[0050] Reference Figure 4The linkage component 51 also includes a linkage rod 512, which extends along a second direction, passes through the lifting block 511, and is fixedly connected to the lifting block 511. The side wall of the first moving component 53 has a first arc-shaped groove 531, and the side wall of the second moving component 54 has a second arc-shaped groove 541. The first arc-shaped groove 531 and the second arc-shaped groove 541 intersect each other. The linkage rod 512 includes a first linkage post 5121 and a second linkage post 5122 fixedly connected. The diameter of the first linkage post 5121 is smaller than the diameter of the second linkage post 5122. The first linkage post 5121 passes through the first arc-shaped groove 531, and the first linkage post 5121 slides into the first arc-shaped groove 531, with the clearance controlled between 0.01 and 0.03 mm. The second linkage post 5122 passes through the second arc-shaped groove 541, and the second linkage post 5122 and the second arc-shaped groove 541 slide and engage, with the engagement clearance also controlled between 0.01-0.03mm. The first clamping member 55 is fixed to the lower surface of the first moving member 53, and the second clamping member 56 is fixed to the lower surface of the second moving member 54. The first clamping member 55 and the second clamping member 56 are made of rubber, and the surfaces of the clamping blocks that contact the wire are frosted. The first clamping member 55 has a first positioning groove 551 for limiting the wire at one end facing the second clamping member 56, and the second clamping member 56 has a second positioning groove 561 for limiting the wire at one end facing the first clamping member 55. The width of the first positioning groove 551 and the second positioning groove 561 is 0.2-0.3mm larger than the wire diameter, and the depth is 1.2-1.5 times the wire diameter.

[0051] Reference Figure 1 , Figure 3 and Figure 4 When clamping the wire, the second lifting cylinder 52 drives the lifting seat 41 to rise and fall, thereby driving the linkage 51 to move. The lifting block 511 of the linkage 51 slides in the lifting groove 47, while the linkage rod 512 moves with the lifting block 511. Since the first linkage post 5121 of the linkage rod 512 passes through the first arc-shaped groove 531 and the second linkage post 5122 passes through the second arc-shaped groove 541, and the first arc-shaped groove 531 and the second arc-shaped groove 541 intersect each other, the movement of the linkage rod 512 causes the first moving member 53 and the second moving member 54 to slide in the sliding groove 48 along the first direction. The movement of the first moving member 53 and the second moving member 54 then drives the first clamping member 55 and the second clamping member 56 to move, respectively. When the first clamping member 55 and the second clamping member 56 approach each other, the first positioning groove 551 and the second positioning groove 561 will gradually limit the wire, ultimately achieving stable clamping of the wire. This mechanism, through the cooperation of the linkage rod 512 and the arc-shaped groove, transforms the lifting motion of the lifting seat 41 into the horizontal motion of the first moving part 53 and the second moving part 54, thereby enabling the clamping block to clamp the wire. It has an ingenious structure, is easy to operate, and can meet the precise clamping requirements of different wires.

[0052] Reference Figure 4 One end of the first moving member 53 is integrally formed with a second guide block 532. The second moving member 54 has a first guide groove 542 on its side wall facing the first moving member 53. The first guide groove 542 extends along the first direction and both ends of the first guide groove 542 are open. The second guide block 532 is located in the first guide groove 542. The second guide block 532 slides and engages with the first guide groove 542, which increases the stability of the first moving member 53 and the second moving member 54 moving along the first direction.

[0053] Reference Figure 2 , Figure 5 and Figure 6 In this embodiment, there are two knitting and cutting mechanisms 6, which are arranged at intervals along a first direction. Specifically, each knitting and cutting mechanism 6 includes a sliding rod 61, a first cutting cylinder 62, a second cutting cylinder 63, and a second cylinder 64. Each bearing seat 42 has a sliding hole 49 at its end, which extends along a second direction and is open at both ends. The sliding rod 61 is located inside the sliding hole 49 and slides in conjunction with the sliding hole 49. The second cylinder 64 is fixed to the sliding seat 31, and the piston rod of the second cylinder 64 is fixedly connected to the end of the sliding rod 61. A fixing rod 611 is integrally formed at the end of the sliding rod 61 facing the clamping assembly 5. A through cutting hole 621 is opened at the end of the cutting cylinder, and the cutting cylinder is sleeved on the fixing rod 611 and fixedly connected to the fixing rod 611.

[0054] Reference Figure 5 and Figure 6 The second cutting cylinder 63 includes a first half-cylinder 631 and a second half-cylinder 632. The first half-cylinder 631 is fixed to the side wall of the first clamping member 55 near the support block, and the second half-cylinder 632 is fixed to the side wall of the second clamping member 56 near the support block. When the end of the first clamping member 55 abuts against the end of the second clamping member 56, the side wall of the first half-cylinder 631 abuts against the side wall of the second half-cylinder 632, and the two combine to form a cylindrical second cutting cylinder 63. A semi-circular first through hole 634 is opened on the side wall of the first half-cylinder 631 near the second half-cylinder 632, and a semi-circular second through hole 635 is opened on the side of the second half-cylinder 632 near the first half-cylinder. Both the first through hole 634 and the second through hole 635 extend along a second direction. When the side wall of the first half-cylinder 631 abuts against the side wall of the second half-cylinder 632, the first through hole 634 and the second through hole 635 combine to form a through-hole, through which the wire can pass.

[0055] Reference Figure 5It is worth noting that the diameter of the cutting hole 621 is smaller than the outer diameter of the second cutting tube 63, and the diameter of the cutting hole 621 is 0.5 mm larger than the diameter of the wire. The inner diameter of the threading hole is also 0.5 mm larger than the diameter of the wire. Both the first half-tube 631 and the second half-tube 632 have a cutting chamfer 633 at their ends facing the first cutting tube 62, with an angle of 30°. When the first cutting tube 62 and the second cutting tube 63 are engaged to cut the wire, their coaxiality error does not exceed 0.05 mm, and their perpendicularity error does not exceed 0.1 mm. When the first cutting tube 62 moves towards the second cutting tube 63, and its end abuts against the cutting chamfer 633, the first cutting tube 62 and the second cutting tube 63 together complete the circumferential cutting of the wire.

[0056] Reference Figure 2 , Figure 5 and Figure 6 When wire cutting is required, the second cylinder 64 starts working, and its piston rod extends and retracts, causing the sliding rod 61 to slide in the sliding hole 49 along the second direction. Since the cutting cylinder is sleeved on the fixed rod 611 and fixedly connected to the fixed rod 611, the movement of the sliding rod 61 will cause the cutting cylinder to move together. The wire passes through the through hole formed by the combination of the first half-cylinder 631 and the second half-cylinder 632 and is in the position to be cut. At this time, the first cutting cylinder 62 moves towards the second cutting cylinder 63 under the drive of the second cylinder 64. When the annular edge of the end of the first cutting cylinder 62 is tightly attached to the surface of the cutting chamfer 633, since the diameter of the cutting hole 621 is smaller than the outer diameter of the second cutting cylinder 63, and with the reasonable design of the cutting chamfer 633 and the high-precision fit between the two, the first cutting cylinder 62 and the second cutting cylinder 63 cooperate with each other to apply pressure to the wire, thereby realizing the circumferential cutting of the wire.

[0057] Reference Figure 1 Each sliding seat 31 has a hopper 34 fixedly installed at one end facing the clamping mechanism. The top and bottom of the hopper 34 are open, and the hopper 34 is located directly below the braiding and cutting mechanism 6. Two waste boxes 14 are also fixedly installed on the upper surface of the base plate 11. The waste boxes 14 correspond one-to-one with the hoppers 34. The waste boxes 14 are located directly below the hoppers 34, and the top of the waste boxes 14 is open. When the braiding and cutting mechanism 6 cuts the wire, the cut waste will fall through the top of the hopper 34 into the waste box 14 located directly below it, thereby collecting the cutting waste.

[0058] The implementation principle of the above embodiment is as follows: In actual operation, firstly, according to the model of the wire to be processed, the piston rod is driven to extend and retract by the first cylinder 33, which drives the sliding seat 31 to move along the first direction and adjusts the cutting component to a suitable position; then, the lifting seat 41 is driven to rise and fall by the first lifting cylinder 43 to adjust the clamping component 5 to a suitable height; then, the wire is passed through the through hole formed by the combination of the first half-cylinder 631 and the second half-cylinder 632; then, the lifting seat 41 is driven to rise and fall by the second lifting cylinder 52, so that the first clamping member 55 and the second clamping member 56 move closer to each other. Under the cooperation of the linkage rod 512 and the arc groove, the first moving member 53 and the second moving member 54 move in the sliding groove 48, thereby driving the first clamping member 55 and the second clamping member 56 to stably clamp the wire; finally, the sliding rod 61 is driven to move by the second cylinder 64, pushing the first cutting cylinder 62 to move toward the second cutting cylinder 63, and the cutting hole 621 and the cutting chamfer 633 are used to complete the cutting of the wire braid.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
