[0002] Needle guides are an important accessory in the textile industry, used in textile machinery such as double-cylinder sock knitting machines. Their main function is to guide and fix the knitting needles, ensuring accurate movement and positioning of the needles within the machine, thereby enabling the weaving and shaping of the fabric.

[0003] In the production process of guide pin sheets, the positioning part of the guide pin sheet needs to be bent and then milled flat before it can be put into use. However, in existing production equipment, bending and milling processes are usually separate steps, which is very unfavorable for the production of guide pin sheets. Summary of the Invention

[0066] Referring to Figures 1 to 3 and Figure 8, the guide pin milling machine according to the first aspect of this application includes: a frame 10, a feeding mechanism 20, a milling mechanism 30, and a drive mechanism 40. A feeding mechanism 20 is mounted on the frame 10 and is used to feed the guide pin 1. A milling mechanism 30 is slidably mounted on the frame 10 and located on one side of the feeding mechanism 20. The milling mechanism 30 is used to bend and mill a portion of the structure of the guide pin 1 fed by the feeding mechanism 20. The milling mechanism 30 includes a bending wheel 31 and a milling wheel 32. The bending wheel 31 and the milling wheel 32 are located in the same plane. The bending wheel 31 and the milling wheel 32 bend and mill the guide pin 1 by passing through a portion of the structure of the guide pin 1, respectively. A driving mechanism 40 is mounted on the frame 10 and is connected to the feeding mechanism 20 and the milling mechanism 30, respectively. The driving mechanism 40 is used to drive the feeding mechanism 20 to feed the guide pin 1. The driving mechanism 40 can also be used to drive the milling mechanism 30 to move on the guide pin 1. The bending wheel 31 and the milling wheel 32 are used to bend and mill the guide pin 1, respectively.

[0067] Specifically, this application discloses a guide pin sheet bending and milling integrated machine, mainly comprising a frame 10, a feeding mechanism 20, a bending and milling mechanism 30, and a drive mechanism 40. The frame 10 serves as the basic support structure of the entire equipment, bearing the feeding mechanism 20, the bending and milling mechanism 30, and the drive mechanism 40. The frame 10 needs to have sufficient strength and stability to ensure the stability and accuracy of the entire equipment during operation. The feeding mechanism 20 is mounted on the frame 10 and can automatically feed the guide pin sheet 1. The feeding mechanism 20 can use existing automatic feeding devices, such as roller feeding devices, belt feeding devices, etc., as long as they can achieve continuous and stable feeding of the guide pin sheet 1. The bending and milling mechanism 30 includes a bending wheel 31 and a milling wheel 32. The bending and milling mechanism 30 is translatably mounted on the frame 10 and located on one side of the feeding mechanism 20. The bending wheel 31 and the milling wheel 32 are located in the same plane to ensure precise bending and milling of the guide pin sheet 1. The bending wheel 31 is mainly used to bend part of the guide pin 1, while the milling wheel 32 is used to mill the guide pin 1. The drive mechanism 40 is mounted on the frame 10 and is connected to the feeding mechanism 20 and the bending and milling mechanism 30 respectively. The main function of the drive mechanism 40 is to drive the feeding mechanism 20 to convey the guide pin 1, drive the feeding mechanism 20 to convey the guide pin 1 to the bending and milling mechanism 30, and drive the bending and milling mechanism 30 to move on the guide pin 1, so that the bending wheel 31 and the milling wheel 32 move on the guide pin 1 to realize the bending and milling operations.

[0068] In this embodiment, when the feeding mechanism 20 delivers the guide pin 1 to the bending wheel 31 and milling wheel 32 of the milling mechanism 30, the bending wheel 31 first bends the part of the guide pin 1 that needs to be bent, and then the milling wheel 32 mills the protruding part of the guide pin 1. These two operations can be completed continuously in the same feeding process, thereby greatly improving production efficiency. In addition, the positions of the bending wheel 31 and the milling wheel 32 can be changed to meet the processing requirements of milling before bending. It is understood that the drive mechanism 40 can adopt a drive system composed of a motor, reducer, transmission device, etc., to achieve synchronous control of feeding and milling. By controlling the speed and direction of the motor, the feeding speed and the moving speed and position of the milling mechanism 30 can be precisely controlled.

[0069] The integrated bending and milling machine for guide needles according to the embodiments of this application has at least the following beneficial effects: the bending wheel 31 and the milling wheel 32 on the bending and milling mechanism 30 sequentially bend the protruding part of the guide needle 1 and then mill the bent part flat, thus processing the guide needle 1 to meet the production requirements of textiles. The integrated setting of bending and milling can avoid repeated feeding of the guide needle 1, and at the same position reference, the guide needle 1 can be bent and milled, thereby avoiding the processing error caused by different references after multiple feedings. Furthermore, it can also avoid the guide needle 1 being unsuitable for stacking after bending, which would make it inconvenient for further milling processing. In addition, the integrated bending and milling machine for guide needles of this application realizes automatic feeding, precise bending and milling processing of the guide needle 1 through the cooperation of the frame 10, the feeding mechanism 20, the bending and milling mechanism 30 and the drive mechanism 40. The integrated bending and milling machine for guide needles of this application has a compact structure, is easy to operate and has high production efficiency, and can also be widely used in the processing of other knitting needles in the textile industry.

[0070] Referring to Figures 4 to 6, in some embodiments of this application, the feeding mechanism 20 includes a feeding assembly 21 and a rotatable conveying ratchet 22. Both the feeding assembly 21 and the conveying ratchet 22 are mounted on the frame 10. The feeding assembly 21 is located on one side of the conveying ratchet 22 and is used to store the guide pin 1. The conveying ratchet 22 is provided with a plurality of receiving slots, which are spaced apart on the periphery of the conveying ratchet 22. The length direction of the receiving slots is parallel to the axial direction of the conveying ratchet 22. The receiving slots are used to receive the guide pin 1. The feeding assembly 21 is used to convey the guide pin 1 to the conveying ratchet 22. The rotation of the conveying ratchet 22 can cause the guide pin 1 in the receiving slots to flip.

[0071] Specifically, the feeding mechanism 20 consists of a feeding assembly 21 and a conveying ratchet 22. The feeding assembly 21 stores a large number of guide pin pieces 1, which can be pushed one by one into the receiving slots of the conveying ratchet 22 via structures such as push rods or vibratory feeders. This ensures a continuous supply of guide pin pieces 1 and automates the feeding process, greatly improving production efficiency. The conveying ratchet 22 has multiple receiving slots spaced apart on its circumference. The length direction of these receiving slots is parallel to the axis of the conveying ratchet 22 to stably accommodate the guide pin pieces 1. When the guide pin piece 1 is pushed into the receiving slot, it is driven to flip as the conveying ratchet 22 rotates. During rotation, the spaced receiving slots flip sequentially, moving the guide pin piece 1 to the milling mechanism 30.

[0072] It should be noted that the flipping action exposes the machining surfaces of the guide pin pieces 1 directly below the milling mechanism 30, facilitating comprehensive machining by the subsequent bending wheel 31 and milling wheel 32. Furthermore, the rotation speed and angle of the feed ratchet 22 can be precisely controlled by the drive mechanism 40, ensuring that each guide pin piece 1 receives accurate and consistent machining. In this embodiment, the coordinated operation of the feeding assembly 21 and the feed ratchet 22 automates and continuously feeds the guide pin pieces 1, significantly improving production efficiency and machining accuracy. Simultaneously, this design reduces the need for manual intervention, lowers labor intensity, and enhances production safety.

[0073] It should also be noted that the conveying ratchet 22 in this embodiment is equipped with a ratchet and a pawl (not shown in the figure). The ratchet has a receiving groove, which cooperates with the pawl to fix the guide pin 1 in the receiving groove. During the feeding process of the guide pin 1, the ratchet achieves the separation and transfer of the guide pin 1 one by one through the meshing of its teeth and the pawl. Its specific structure is a conventional technology well known to those skilled in the art, and will not be described in detail here. It can realize the sequential and orderly feeding of the guide pin 1 into the next process of the production line.

[0074] Referring to Figures 6 to 7 and Figure 9, in some embodiments of this application, the feeding assembly 21 includes a hopper 211 and a feeding platform 212. The hopper 211 is vertically mounted on the frame 10 and is used to hold the guide pin 1. The feeding platform 212 is slidably mounted on the frame 10 and located on one side of the bottom of the hopper 211. A pusher 2121 is provided on the feeding platform 212. The end of the pusher 2121 near the bottom of the hopper 211 is a contoured end that matches the shape of the guide pin 1. The pusher 2121 reciprocates at the bottom of the hopper 211.

[0075] Specifically, the feeding assembly 21 consists of a hopper 211 and a feeding platform 212, which work together to achieve an efficient and stable feeding process. The hopper 211 is vertically mounted on the frame 10 and is used to hold a large number of guide pin pieces 1. The vertically mounted hopper 211 takes into account the shape and size of the guide pin pieces 1 to ensure that the guide pin pieces 1 can be stably stacked within it. At the same time, the bottom of the hopper 211 is designed to be open so that the pusher piece 2121 on the feeding platform 212 can push the bottommost guide pin piece 1 onto the conveying ratchet 22 on one side. The feeding platform 212 is slidably mounted on the frame 10 and is located on one side of the bottom of the hopper 211, so that the feeding platform 212 can drive the pusher piece 2121 to move closer to or away from the hopper 211 as needed. The pusher piece 2121 reciprocates at the bottom of the hopper 211 to achieve automatic feeding of the guide pin pieces 1.

[0076] It should be noted that the end of the pusher piece 2121 near the bottom of the hopper 211 is designed as a contoured end, which matches the shape of the guide pin piece 1. This ensures that the pusher piece 2121 fits tightly against the guide pin piece 1 when pushing it, preventing displacement or jamming during the pushing process. At the same time, the contoured end design also reduces friction between the pusher piece 2121 and the guide pin piece 1, reducing wear and noise.

[0077] In this embodiment, when feeding is required, the feeding platform 212 moves closer to the hopper 211, ensuring that the contoured end of the pusher 2121 fits tightly against the bottom guide pin 1. Then, the pusher 2121 reciprocates, pushing the guide pin 1 out of the hopper 211 and into the receiving groove of the conveying ratchet 22. After feeding is complete, the feeding platform 212 returns to its original position, awaiting the next feeding. Therefore, it can be understood that the feeding assembly 21 not only improves production efficiency but also reduces labor intensity and the need for manual intervention, providing reliable material support for the bending and milling of the guide pin 1.

[0078] Referring to Figures 4 and 6, in some embodiments of this application, a drive wheel 221 is provided at one end of the conveying ratchet 22. The drive wheel 221 is connected to the conveying ratchet 22, and the drive wheel 221 drives the conveying ratchet 22 to rotate intermittently. A drive rod 222 is connected to one side edge of the drive wheel 221. The drive rod 222 is driven by the drive mechanism 40. The other end of the drive rod 222 is connected to the output end of the drive mechanism 40. A rotating gear 223 is provided at the outer end of the drive wheel 221. A locking member 2211 is engaged between the teeth of the rotating gear 223. The drive rod 222 can push the locking member 2211 to disengage from between the teeth of the rotating gear 223.

[0079] The conveying ratchet 22 is a key component in the integrated milling and bending machine for intermittently conveying the guide pin 1. Specifically, a drive wheel 221 is provided at the front end of the conveying ratchet 22. The drive wheel 221 is tightly connected to the conveying ratchet 22 and rotates coaxially to ensure that the two can rotate synchronously. The drive wheel 221 is cam-shaped, with connecting parts on both sides of its edge. One edge is used to connect to the drive mechanism 40, and a drive rod 222 is connected to the other edge. The drive rod 222 is driven by the drive mechanism 40. More specifically, the other end of the drive rod 222 is connected to the output end of the drive mechanism 40. When the drive mechanism 40 is working, it pushes the drive wheel 221 through the drive rod 222, thereby causing the conveying ratchet 22 to rotate intermittently.

[0080] To ensure the precise intermittent rotation of the conveying ratchet 22, a rotating gear 223 is provided at the outer end of the drive wheel 221. A locking member 2211 engages between the teeth of this rotating gear 223. This design allows for precise control and adjustment of the rotation of the conveying ratchet 22. In this embodiment, when the drive rod 222 is pushed by the drive mechanism 40, the drive rod 222 further pushes the locking member 2211 to the right, causing the driving force of the drive rod 222 to temporarily disengage the locking member 2211 from the teeth of the rotating gear 223, thus allowing the drive wheel 221 and the conveying ratchet 22 to rotate. When the drive rod 222 retracts to the left, the locking member 2211 re-engages between the teeth of the rotating gear 223, thereby locking the positions of the drive wheel 221 and the conveying ratchet 22 until the next push of the drive rod 222. Through the engagement of the snap-fit ​​component 2211, the conveying ratchet 22 can achieve precise intermittent rotation, thereby ensuring that each guide pin 1 is conveyed to the bending wheel 31 and the milling wheel 32 for processing at the correct time and position. This precise control not only improves production efficiency but also ensures the processing quality of each guide pin 1. Therefore, it can be understood that the components at the front end of the conveying ratchet 22 provide stable and reliable material conveying support for the bending and milling processing of the guide pin 1.

[0081] Furthermore, in some embodiments of this application, as can be seen from the above embodiments, if a drive rod 222 is connected to one side edge of the cam-shaped drive wheel 221, a rotatable thrust member 2212 can also be provided on the other side edge of the drive wheel 221. One end of the thrust member 2212 is rotatably disposed on the drive wheel 221, and the other end of the thrust member 2212 can be engaged between the teeth of the rotating gear 223. Specifically, a rotatable thrust member 2212 is provided on the other side edge of the drive wheel 221. In order to further increase the stability and accuracy of the rotation of the conveying ratchet 22, one end of the thrust member 2212 is rotatably disposed on the drive wheel 221, and the other end can be engaged between the teeth of the rotating gear 223. When the thrust member 2212 is engaged between the teeth of the rotating gear 223, it can effectively prevent the drive wheel 221 and the conveying ratchet 22 from rotating unexpectedly during non-drive periods. When the drive rod 222 pushes the drive wheel 221 to rotate, the drive wheel 221 rotates clockwise, and the thrust member 2212 will automatically disengage from the teeth of the rotating gear 223 due to the rotation of the drive wheel 221; when the drive wheel 221 stops rotating, the thrust member 2212 will re-engage from the teeth of the rotating gear 223 under the action of gravity or other reset mechanisms, thereby locking the position of the drive wheel 221.

[0082] The thrust stop 2212 further enhances the rotational stability and accuracy of the feed ratchet 22. The presence of the thrust stop 2212 effectively prevents accidental rotation of the feed ratchet 22 during non-working periods, thus ensuring that each guide pin 1 is fed to the bending wheel 31 and milling wheel 32 for processing at the correct time and position. This not only improves production efficiency but also further ensures the processing quality of the guide pin 1. Therefore, the thrust stop 2212 makes the overall performance of the guide pin milling machine superior, better suited to the demands of efficient and precise production.

[0083] Referring to Figures 6 and 7, in some embodiments of this application, the feeding mechanism 20 further includes a material-pushing assembly 23. The material-pushing assembly 23 is disposed on the frame 10 and located above the conveying ratchet 22. The material-pushing assembly 23 includes a clamp 231 and a sliding mechanism 232. The clamp 231 is slidably disposed above the conveying ratchet 22, and the sliding direction of the clamp 231 is along the axial direction of the conveying ratchet 22. The jaws on the clamp 231 are used to engage with the guide pin 1, and the clamp 231 is used to drive the guide pin 1 to slide in the receiving groove of the conveying ratchet 22. The sliding mechanism 232 includes a slide rod and a slide rail. The slide rod is slidably disposed on the slide rail, and the clamp 231 is disposed at one end of the slide rod. The slide rod drives the clamp 231 to slide on the slide rail. The feeding mechanism 20 further includes the material-pushing assembly 23. The material-pushing assembly 23 is disposed on the frame 10 and located above the conveying ratchet 22. The feeding assembly 23 is used to ensure that the guide pin 1 slides correctly and stably in the receiving groove of the conveying ratchet 22.

[0084] Specifically, the feeding assembly 23 mainly consists of two parts: a clamp 231 and a sliding mechanism 232. The clamp 231 is designed to be slidably mounted above the conveying ratchet 22, with its sliding direction along the axis of the conveying ratchet 22, i.e., the front-to-back direction shown in the figure. When the clamp 231 slides, the guide pin 1 can be slid to the underside of the bending wheel 31 and the milling wheel 32. That is, the sliding mechanism 232 enables the clamp 231 to precisely control the position of the guide pin 1 in the receiving groove. The clamp 231 is also provided with jaws, which are specially designed to engage with the protruding part of the guide pin 1, thereby ensuring the stability of the guide pin 1 during sliding. Therefore, when the conveying ratchet 22 drives the guide pin 1 to rotate, the protruding part of the guide pin 1 can be engaged in the jaws of the clamp 231 by the jaws. Therefore, in this way, the caliper 231 can effectively drive the guide pin 1 to slide in the receiving groove of the conveying ratchet 22 to meet the subsequent processing requirements.

[0085] To enable the sliding function of the caliper 231, the material-feeding assembly 23 also includes a sliding mechanism 232. The sliding mechanism 232 consists of a sliding rod and a slide rail. The sliding rod is designed to be slidably mounted on the slide rail, ensuring both smoothness and precision of the sliding motion. The caliper 231 is mounted at one end of the sliding rod, so that when the sliding rod slides on the slide rail, it can drive the caliper 231 to slide as well. In this embodiment, when it is necessary to move the guide pin 1, the sliding mechanism 232 drives the sliding rod to slide on the slide rail, thereby driving the caliper 231 to slide. The caliper 231 then engages with the guide pin 1 through its jaws, ensuring that the guide pin 1 can move stably and accurately to the target position during the sliding process in the forward and backward direction. The material-feeding assembly 23 provides reliable material positioning support for the bending and milling of the guide pin 1, not only improving production efficiency but also further ensuring the processing accuracy and quality of each guide pin 1.

[0086] Referring to Figures 4 and 7, in some embodiments of this application, the feeding mechanism 20 further includes a discharging assembly 24, which is disposed on the other side of the conveying ratchet 22. The discharging assembly 24 includes a discharging platform 241, one end of which abuts against the conveying ratchet 22. The discharging platform 241 is used to receive the milled guide pin 1 in the conveying ratchet 22. The feeding mechanism 20 also includes the discharging assembly 24. The discharging assembly 24 is carefully disposed on the other side of the conveying ratchet 22, that is, on the opposite side of the feeding assembly 21 located on one side of the conveying ratchet 22. It can be understood that the main function of the discharging assembly 24 is to receive the milled guide pin 1 in the conveying ratchet 22.

[0087] Specifically, the unloading assembly 24 mainly consists of an unloading platform 241. One end of the unloading platform 241 is in close contact with the conveying ratchet 22 to ensure that the guide pin 1 output from the conveying ratchet 22 can slide smoothly and accurately onto the unloading platform 241. This design not only simplifies the material flow path but also greatly improves production efficiency. In this embodiment, after the guide pin 1 has completed milling on the conveying ratchet 22, it will be conveyed to the position where it contacts the unloading platform 241 as the conveying ratchet 22 rotates. During the unloading process, a mechanism for unloading can be provided on the lower side of the unloading platform 241 to remove the guide pin 1 from the receiving groove of the conveying ratchet 22; the height difference and tilt angle between the unloading platform 241 and the conveying ratchet 22 can also be set so that the guide pin 1 can slide smoothly onto the unloading platform 241 and be arranged in a certain order. Therefore, it should be noted that the specific structural form of the feeding component 24 is not limited, as long as the feeding component 24 provides reliable material feeding support for the bending and milling of the guide pin 1.

[0088] Referring to Figures 7 to 9, in some embodiments of this application, the milling mechanism 30 further includes a slide 33, a bending wheel 31 and a milling wheel 32 slidably disposed on the slide 33. The slide 33 includes a slide table that can slide along a first direction and a second direction. The first direction and the second direction are perpendicular to each other. The first direction extends horizontally along the axial direction of the conveying ratchet 22, and the second direction extends horizontally along the radial direction of the conveying ratchet 22.

[0089] In the guide pin bending and milling integrated machine, the bending and milling mechanism 30 is responsible for performing the bending and milling operations of the guide pin 1. To improve operational flexibility and precision, the bending and milling mechanism 30 is equipped with a slide 33. The slide 33 allows the bending wheel 31 and the milling wheel 32 to slide on the slide 33 under the drive of the drive mechanism 40. The slide 33 provides greater operational freedom, allowing the bending wheel 31 and the milling wheel 32 to move precisely to the appropriate position as needed, while also satisfying the requirement of the drive mechanism 40 to drive the slide 33 to slide to perform bending and milling tasks.

[0090] Specifically, the slide 33 includes a slide table that can slide along a first direction and a second direction. These two directions are perpendicular to each other, providing greater operational flexibility. The first direction extends horizontally along the axial direction of the conveying ratchet 22, i.e., the front-to-back direction shown in the figure, so the bending wheel 31 and the milling wheel 32 can be finely adjusted in this direction to accommodate guide pin pieces 1 of different lengths or with different protrusion positions. The second direction extends horizontally along the radial direction of the conveying ratchet 22, i.e., the left-to-right direction shown in the figure, which allows the bending wheel 31 and the milling wheel 32 to move closer to or further away from the conveying ratchet 22, thereby driving the bending wheel 31 and the milling wheel 32 to slide in the left-to-right direction, and thus driving the bending wheel 31 and the milling wheel 32 to bend and mill the guide pin piece 1, respectively.

[0091] It should be noted that, to achieve this bidirectional sliding function, the slide 33 can be equipped with a high-precision guide rail and slider system, as well as the necessary locking mechanism, to ensure the positional stability of the bending wheel 31 and the milling wheel 32 during machining. The slide 33 greatly improves the flexibility and precision of the bending and milling mechanism 30, enabling the integrated bending and milling machine with guide pins to adapt to a wider range of machining needs and improve machining quality and efficiency. This bidirectional sliding function also makes the machine exhibit greater adaptability and flexibility when dealing with complex or customized machining tasks.

[0092] Furthermore, in some embodiments of this application, referring to Figures 7 to 9, the milling mechanism 30 further includes a drive member 34. The drive member 34 is disposed on one side of the milling wheel 32, and its output end is connected to the milling wheel 32. The drive member 34 drives the milling wheel 32 to rotate. To ensure that the milling wheel 32 can perform milling operations stably and efficiently, the milling mechanism 30 also includes a drive member 34. The drive member 34 is carefully disposed on one side of the milling wheel 32 to ensure that the driving force can be directly and effectively transmitted to the milling wheel 32. The output end of the drive member 34 is tightly connected to the milling wheel 32. The connection can be achieved through a coupling, a transmission belt, or other suitable transmission mechanism to ensure smooth transmission of the driving force. In this embodiment, the drive member 34 can be a motor, a hydraulic motor, or other type of driver. However, it is not specifically limited, as long as it provides a stable and controllable power source for the milling wheel 32, enabling the guide pin milling machine to perform milling operations efficiently and accurately.

[0093] Referring to Figure 8, in some embodiments of this application, multiple bending wheels 31 are provided, arranged sequentially at intervals. The axial directions of the multiple bending wheels 31 are all perpendicular to the bending direction of the guide pin 1, and the heights of the axes of the multiple bending wheels 31 rise or fall sequentially. In the guide pin milling and bending machine, the bending operation is a key step. To ensure that the guide pin 1 can be accurately bent in the predetermined bending direction, the milling and bending mechanism 30 may be equipped with multiple bending wheels 31.

[0094] Specifically, the bending wheels 31 are arranged at intervals to ensure that the guide pin 1 can complete the bending operation gradually and continuously during the transmission process. The axial directions of the multiple bending wheels 31 are all perpendicular to the bending direction of the guide pin 1, which allows the bending wheels 31 to apply a uniform bending force along the width direction of the guide pin 1, thereby ensuring the accuracy and consistency of bending. To further improve the flexibility and precision of bending, the height of the axes of the multiple bending wheels 31 increases or decreases sequentially. This gradient arrangement allows the guide pin 1 to gradually change its bending angle and direction when passing through bending wheels 31 at different heights, thereby achieving gradual and continuous bending. This design not only improves the flexibility of bending but also enables the integrated machine to adapt to the bending requirements of more types of guide pin 1. The gradient arrangement of the multiple bending wheels 31 and the design of the perpendicular axial direction enable the guide pin milling and bending integrated machine to achieve high-precision and high-flexibility bending operations. This design not only improves production efficiency but also greatly expands the application range of the machine, enabling it to adapt to the processing requirements of more types of guide pin 1.

[0095] Referring to Figures 7 and 9 to 10, in some embodiments of this application, the bending and milling mechanism 30 further includes a fixing component 35. The fixing component 35 is disposed at the other end of the conveying ratchet 22 and located below the bending wheel 31 and the milling wheel 32. The fixing component 35 includes a fixing seat 351 and a second clamping block 353. The fixing seat 351 is fixed on the frame 10, and a first clamping block 352 is disposed at the upper end of the fixing seat 351. The second clamping block 353 is slidably disposed on the fixing seat 351 and located on one side of the first clamping block 352, and the second clamping block 353 is close to the first clamping block 352 to clamp and fix the guide pin 1. In order to ensure the stability and machining accuracy of the guide pin 1 during bending and milling, the bending and milling mechanism 30 is also equipped with a fixing component 35. The fixing component 35 is carefully disposed at the other end of the conveying ratchet 22 and located below the bending wheel 31 and the milling wheel 32. This layout ensures that the guide pin 1 can be immediately fixed after delivery, providing stable support for subsequent bending and milling operations.

[0096] Specifically, the fixing assembly 35 mainly consists of a fixing base 351, a first clamping block 352, and a second clamping block 353. The fixing base 351 is firmly mounted on the frame 10, serving as the foundation of the entire fixing assembly 35. The first clamping block 352 is fixed at the upper end of the fixing base 351 and is used to cooperate with the second clamping block 353 to clamp the guide needle piece 1. It should be noted that a contoured groove is provided on the side of the first clamping block 352 facing the second clamping block 353. This contoured groove matches the shape of the guide needle piece 1, which can better fix the guide needle piece 1. The second clamping block 353 is slidably mounted on the fixing base 351 and located on one side of the first clamping block 352. Therefore, the second clamping block 353 can move closer to or further away from the first clamping block 352 as needed to accommodate guide needle pieces 1 of different widths and thicknesses; in addition, the second clamping block 353 can be driven away from or closer to the first clamping block 352 by the driving mechanism 40 to clamp and fix the guide needle piece 1. When the second clamping block 353 approaches the first clamping block 352, they together form a clamping space to securely fix the guide pin 1 and prevent it from moving or deforming during bending and milling.

[0097] Furthermore, to enable the sliding function of the second clamping block 353, the fixed base 351 may be equipped with a guide rail or a slide groove, while the second clamping block 353 is fitted with a matching slider or roller. In addition, a reset component (not shown in the figure) such as a spring, cylinder, or electric push rod may also be provided to drive the sliding reset of the second clamping block 353, facilitating the clamping operation of the next guide pin 1.

[0098] Referring to Figures 7 and 9, in some embodiments of this application, the fixing component 35 further includes a limiting groove 354, which is disposed between one side of the first clamping block 352 and one end of the conveying ratchet 22. The opening of the limiting groove 354 is aligned with the receiving groove on the conveying ratchet 22, and the guide pin 1 can be inserted into the opening of the limiting groove 354.

[0099] Furthermore, the fixing component 35 not only fixes the guide pin 1 but also provides precise positioning of the guide pin 1 to ensure its positional accuracy during processing. To this end, the fixing component 35 is also equipped with a limiting groove 354. The limiting groove 354 is located between one side of the first clamping block 352 and one end of the conveying ratchet 22, ensuring that the guide pin 1 can smoothly enter the limiting groove 354 when it is transferred from the conveying ratchet 22 to the fixing component 35. The opening of the limiting groove 354 is aligned with the receiving groove on the conveying ratchet 22. When the guide pin 1 is transferred from the conveying ratchet 22 to the fixing component 35, it can accurately slide from the receiving groove into the opening of the limiting groove 354, thereby ensuring the accuracy of the guide pin 1's position and the smoothness of its transfer. In addition, the guide pin 1 can pass through the opening of the limiting groove 354; the opening not only serves as a limiting element but also ensures the stability of the guide pin 1 during processing. When the guide pin 1 is fixed between the first clamping block 352 and the second clamping block 353, the limiting groove 354 prevents it from moving laterally during processing, thus ensuring the accuracy and quality of the processing. The design of the limiting groove 354 not only improves the accuracy and quality of processing but also reduces the scrap rate, providing a strong guarantee for the mass production of the guide pin 1. At the same time, the alignment of the limiting groove 354 with the receiving groove of the conveying ratchet 22 also ensures the smoothness and accuracy of the entire process from conveying to fixing the guide pin 1.

[0100] Referring to Figures 1 to 3 and Figure 11, in some embodiments of this application, the drive mechanism 40 includes a drive source 41, which is mounted on the frame 10. The drive source 41 is connected to the feeding mechanism 20 and the milling mechanism 30 via a first drive assembly 42 and a second drive assembly 43, respectively. In the guide pin milling integrated machine of this application, the drive mechanism 40 ensures the efficient and stable operation of the entire device. The drive mechanism 40 includes a drive source 41. The drive source 41 is securely mounted on the frame 10 to ensure that it can provide stable and continuous power output during device operation. This drive source 41 may be an electric motor, a hydraulic motor, or other types of drive, the specific choice depending on the actual needs of the device and the working environment.

[0101] Specifically, to achieve precise control of the feeding mechanism 20 and the milling mechanism 30, the drive source 41 is connected to the feeding mechanism 20 via the first drive assembly 42 and simultaneously connected to the milling mechanism 30 via the second drive assembly 43. This dual-connection design allows the drive source 41 to simultaneously and independently control the operation of the feeding mechanism 20 and the milling mechanism 30. More specifically, the first drive assembly 42 and the second drive assembly 43 may include a transmission belt, chain, gear, or other suitable transmission mechanism to ensure that the driving force can be smoothly and accurately transmitted to the feeding mechanism 20 and the milling mechanism 30. Of course, these drive assemblies may also be equipped with necessary control systems, such as frequency converters, sensors, etc., to achieve precise control of the feeding and milling processes. In this embodiment, when the drive source 41 is started, the drive source 41 drives the feeding mechanism 20 to run via the first drive assembly 42, gradually feeding the guide pin 1 into the milling area. At the same time, through the second drive assembly 43, the drive source 41 also controls the milling mechanism 30 to perform precise bending and milling operations.

[0102] Therefore, it is understandable that the design of the drive mechanism 40 enables the guide pin milling machine to achieve efficient and stable automated production. By controlling the feeding mechanism 20 and the milling mechanism 30 simultaneously through a single drive source 41, the feeding mechanism 20 and the milling mechanism 30 can cooperate with each other, which not only simplifies the structure of the equipment, but also improves production efficiency and machining accuracy.

[0103] Referring to Figures 11 to 13, in some embodiments of this application, the drive mechanism 40 includes a first drive assembly 42. The drive source 41 is connected to the feeding mechanism 20 through the first drive assembly 42. The first drive assembly 42 includes a first drive cam 421 and a first rocker arm 422. One end of the first rocker arm 422 is rotatably mounted on the frame 10, and the other end is connected to the loading platform 212. The outer side of the first drive cam 421 abuts against the first rocker arm 422. The first drive cam 421 drives the first rocker arm 422 to swing, and the first rocker arm 422 drives the pusher piece 2121 on the loading platform 212 to reciprocate. The drive mechanism 40 precisely controls the movement of the feeding mechanism 20 through the first drive assembly 42, ensuring that the guide pin piece 1 can be stably and accurately fed into the milling area.

[0104] Specifically, the first drive assembly 42 includes a first drive cam 421 and a first rocker arm 422. One end of the first rocker arm 422 is rotatably mounted on the frame 10, so the first rocker arm 422 can periodically oscillate when driven by the first drive cam 421. The other end of the first rocker arm 422 is connected to the loading platform 212, and when the first rocker arm 422 oscillates, it can directly drive the loading platform 212 to perform corresponding actions. The outer side of the first drive cam 421 abuts against the first rocker arm 422. When the drive source 41 drives the first drive cam 421 to rotate, due to its special cam profile shape, it will periodically push the first rocker arm 422 to oscillate. This oscillating action is further transmitted to the loading platform 212, thereby driving the pusher plate 2121 to reciprocate.

[0105] When the pusher plate 2121 slides to the right, it pushes the guide pin plate 1 into the receiving groove of the conveying ratchet 22; when the pusher plate 2121 slides to the left, it prepares for the next feeding action and causes the guide pin plate 1 in the hopper 211 to fall to the right side of the pusher plate 2121 under the action of gravity.

[0106] It is important to note that, to ensure the smooth and precise sliding motion of the pusher piece 2121, the design of the first drive cam 421 and the first rocker arm 422 needs to be extremely precise to ensure that the amplitude, speed, and timing of each swing are consistent. The design of the first drive cam 421 and the first rocker arm 422 enables the feeding mechanism 20 to achieve efficient and stable automatic feeding. Through the ingenious cooperation of the first drive cam 421 and the first rocker arm 422, the reciprocating sliding motion of the pusher piece 2121 is ensured to be both smooth and precise, thus meeting the stringent requirements for feeding accuracy of the guide pin milling machine.

[0107] Further referring to Figures 11 to 13, in some embodiments of this application, the first drive assembly 42 further includes a second drive cam 423 and a second rocker arm 424. The outer side of the second drive cam 423 abuts against the second rocker arm 424. One end of the second rocker arm 424 is rotatably mounted on the frame 10, and the other end of the second rocker arm 424 is connected to the conveying ratchet 22. The second drive cam 423 drives the second rocker arm 424 to swing, and the second rocker arm 424 drives the conveying ratchet 22 to rotate. As can be seen from the above embodiments, in addition to controlling the feeding platform 212 of the feeding mechanism 20 through the first drive cam 421 and the first rocker arm 422, the rotation of the conveying ratchet 22 is also precisely controlled through the second drive cam 423 and the second rocker arm 424, thereby realizing the continuous and stable conveying of the guide pin 1.

[0108] Specifically, the second drive cam 423 and the second rocker arm 424 constitute another drive structure of the first drive assembly 42. Similar to the first drive assembly 42, one end of the second rocker arm 424 is rotatably mounted on the frame 10 to ensure it can swing freely. The other end of the second rocker arm 424 is connected to the drive rod 222 at the front end of the conveying ratchet 22. When the second drive cam 423 rotates under the drive of the drive source 41, its outer side periodically abuts against the second rocker arm 424, thereby driving the second rocker arm 424 to swing. This swinging motion is further transmitted to the drive rod 222 of the conveying ratchet 22, which drives the drive wheel 221 to rotate, thus causing the conveying ratchet 22 to rotate periodically. The rotation of the conveying ratchet 22 is the key to achieving continuous conveying of the guide needle 1.

[0109] It should be noted that the precise mechanism of the second drive cam 423 and the second rocker arm 424 ensures that the conveying ratchet 22 rotates at a constant speed and with a stable torque. It also ensures the appropriate timing for the conveying ratchet 22 to deliver the guide pin 1, thus preventing problems such as jamming, slippage, or insufficient needle material during the conveying process. To ensure the accuracy, stability, and timing of the conveying, the design of the second drive cam 423 and the second rocker arm 424 also requires high precision. Their shape, size, and material selection directly affect the rotational performance of the conveying ratchet 22 and the conveying effect of the guide pin 1. Therefore, the precise coordination of the second drive cam 423 and the second rocker arm 424 ensures the stable rotation of the conveying ratchet 22, thereby achieving continuous and stable conveying of the guide pin 1. Furthermore, the design of the second drive cam 423 and the second rocker arm 424 not only improves production efficiency but also guarantees the positional accuracy and machining quality of the guide pin 1 during the milling process.

[0110] Furthermore, referring to Figures 4, 7, and 11 to 12, in some embodiments of this application, the first drive assembly 42 further includes a fifth drive cam 425 and a fifth rocker arm 426. The fifth drive cam 425 is connected to the fifth rocker arm 426 via a connecting rod 427. One end of the fifth rocker arm 426 is rotatably mounted on the frame 10, and the other end is connected to the feeding mechanism 20. The fifth drive cam 425 drives the fifth rocker arm 426 to reciprocate. As can be seen from the above embodiments, in addition to controlling the loading platform 212 of the feeding mechanism 20 through the first drive cam 421 and the first rocker arm 422, and precisely controlling the rotation of the conveying ratchet 22 through the second drive cam 423 and the second rocker arm 424, the first drive assembly 42 also includes a fifth drive cam 425 and a fifth rocker arm 426. This combination is used to precisely control the feeding assembly 23 on the feeding mechanism 20. The feeding assembly 23 plays a key role in the feeding process of the guide pin 1. The feeding assembly 23 can ensure that the guide pin 1 is accurately fed from the receiving groove of the conveying ratchet 22 into the area below the bending wheel 31 and the milling wheel 32.

[0111] Specifically, the fifth drive cam 425 is connected to the fifth rocker arm 426 via a connecting rod 427. When the fifth drive cam 425 rotates under the drive of the drive source 41, it drives the fifth rocker arm 426 to reciprocate through the connecting rod 427. One end of the fifth rocker arm 426 is rotatably mounted on the frame 10, and the other end is connected to the sliding mechanism 232 of the feeding mechanism 20's feeding assembly 23. The feeding assembly 23 is used to ensure that the guide pin 1 slides correctly and stably in the receiving groove of the conveying ratchet 22 and to accurately feed the guide pin 1 from the receiving groove of the conveying ratchet 22 into the area below the bending wheel 31 and the milling wheel 32. The specific structure of the feeding assembly 23 can be referred to in the aforementioned embodiments, and will not be described in detail here.

[0112] It should be noted that, to ensure the precise and reliable operation of the feeding assembly 23, the design of the fifth drive cam 425 and the fifth rocker arm 426 also needs to be very precise. Their shape, size, and fit directly affect the performance of the feeding assembly 23 and the accuracy of the feeding timing of the guide pin 1. Furthermore, the design of the connecting rod 427 is also crucial. It needs to ensure that the rotation of the fifth drive cam 425 is accurately converted into the reciprocating oscillation of the fifth rocker arm 426, while also withstanding the corresponding loads and impacts and having appropriate rotational connections. Through the precise cooperation of the fifth drive cam 425, connecting rod 427, and fifth rocker arm 426, the stable and accurate operation of the feeding assembly 23 can be ensured, thereby achieving precise feeding of the guide pin 1. This design not only improves production efficiency but also guarantees the positional accuracy and processing quality of the guide pin 1 during the processing.

[0113] Referring to Figures 6 and 11 to 13, in some embodiments of this application, the drive mechanism 40 further includes a second drive assembly 43. The drive source 41 is connected to the milling mechanism 30 through the second drive assembly 43. The second drive assembly 43 includes a third drive cam 431 and a third rocker arm 432. One end of the third rocker arm 432 is connected to the slide block 33 of the milling mechanism 30, and the other end is connected to the third drive cam 431. The third drive cam 431 drives the third rocker arm 432 to reciprocate the milling mechanism 30. The second drive assembly 43 is the key part of the drive mechanism 40 responsible for driving the milling mechanism 30. Through the cooperation of the third drive cam 431 and the third rocker arm 432, the second drive assembly 43 achieves precise control of the milling mechanism 30.

[0114] Specifically, one end of the third rocker arm 432 is connected to the slide 33 of the milling mechanism 30, and the movement of the third rocker arm 432 can be directly transmitted to the milling mechanism 30. The other end of the third rocker arm 432 is connected to the third drive cam 431. When the third drive cam 431 rotates under the drive of the drive source 41, due to its special cam profile shape, it will drive the third rocker arm 432 to swing accordingly. The swing of the third rocker arm 432 can be further converted into the reciprocating movement of the milling mechanism 30 on the slide 33. The corresponding reciprocating movement can drive the bending wheel 31 and the milling wheel 32 to move reciprocally above the guide pin 1, so as to continuously bend and mill the guide pin 1.

[0115] It should be noted that, to ensure the precise and stable movement of the milling mechanism 30, the design of the third drive cam 431 and the third rocker arm 432 needs to be extremely precise. Their shape, size, and material selection directly affect the movement performance, machining quality, and timing of the milling mechanism 30. Furthermore, to further improve the system's stability and accuracy, auxiliary devices such as guide rails and sliders may be needed on the slide block 33 to ensure the stability and accuracy of the milling mechanism 30 during movement. Therefore, through precise control of the second drive assembly 43, the milling mechanism 30 can be ensured to perform precise and stable reciprocating movement when machining the guide pin 1, thereby meeting the accuracy requirements for bending and milling the guide pin 1. The design of the third drive cam 431 and the third rocker arm 432 not only improves production efficiency but also guarantees machining quality, enabling the integrated milling and bending machine for guide pins to meet the high standards of modern industrial production.

[0116] Further, referring to Figures 6 and 11 to 13, in some embodiments of this application, the second drive assembly 43 further includes a fourth drive cam 433 and a fourth rocker arm 434. The middle part of the fourth rocker arm 434 is rotatably mounted on the frame 10. One end of the fourth rocker arm 434 abuts against the outer side of the fourth drive cam 433, and the other end of the fourth rocker arm 434 abuts against the fixing assembly 35 of the milling mechanism 30. The fourth drive cam 433 drives the fourth rocker arm 434 to abut against the fixing assembly 35 of the milling mechanism 30. As can be seen from the above embodiments, in addition to controlling the sliding of the milling mechanism 30 through the third drive cam 431 and the third rocker arm 432, the second drive assembly 43 also includes a fourth drive cam 433 and a fourth rocker arm 434. This combination is used to precisely control the fixing assembly 35 of the milling mechanism 30 to ensure the stable fixation of the guide pin 1 during bending and milling.

[0117] Specifically, the fourth rocker arm 434 is rotatably mounted on the frame 10, allowing it to swing freely when driven. One end of the fourth rocker arm 434 abuts against the outer side of the fourth drive cam 433. When the fourth drive cam 433 rotates under the drive of the drive source 41, it periodically pushes the fourth rocker arm 434 to swing. The other end of the fourth rocker arm 434 abuts against one end of the second clamping block 353 of the fixing component 35 of the milling mechanism 30. This fixing component 35 may be a clamp, pressure plate, or other form of fixing device used to fix the guide pin 1 during processing. The specific structure can be referred to the fixing component 35 in the milling mechanism 30 of the aforementioned embodiment, and will not be described in detail here. When the fourth rocker arm 434 swings under the drive of the fourth drive cam 433, it abuts against the second clamping block 353 of the fixing component 35, thereby achieving stable fixing of the guide pin 1.

[0118] It should be noted that, to ensure the reliability and stability of the fixing effect, the design of the fourth drive cam 433 and the fourth rocker arm 434 also needs to be very precise. Their shape, size, and fit directly affect the performance of the fixing component 35, the machining quality of the guide pin 1, and the timing of clamping the guide pin 1. In addition, auxiliary devices such as springs and buffers may be provided to ensure that the fixing component 35 and the guide pin 1 are not subjected to excessive impact or damage during the pressing process. Through the precise fit of the fourth drive cam 433 and the fourth rocker arm 434, the fixing component 35 of the milling mechanism 30 can stably fix the guide pin 1 during machining, thereby improving machining quality and efficiency. The design of the fourth drive cam 433 and the fourth rocker arm 434 not only simplifies the fixing operation but also improves the automation and safety of the production process.

[0119] Referring to Figures 11 to 13, in some embodiments of this application, the drive source 41 includes a transmission rod 44, which connects the drive source 41 to the first drive assembly 42 and the second drive assembly 43. In the guide pin milling integrated machine of this application, the drive source 41 is connected to the first drive assembly 42 and the second drive assembly 43 via the transmission rod 44, making the entire drive system more compact and efficient. The transmission rod 44, as the output end of the drive source 41, transmits the driving force to the first drive assembly 42 and the second drive assembly 43. This connection method simplifies the structure of the drive mechanism 40 and improves the energy transfer efficiency.

[0120] In this embodiment, the transmission rod 44 can be a rigid rod or a flexible transmission shaft, depending on specific design requirements and spatial layout. The transmission rod 44 is connected to the drive source 41 via a chain or belt, and is connected to the input ends of the first drive assembly 42 and the second drive assembly 43 via a connector or bevel gear to split or change direction. When the drive source 41 starts, it transmits power to both the first drive assembly 42 and the second drive assembly 43 simultaneously via the transmission rod 44.

[0121] Specifically, in the first drive assembly 42, the power from the drive source 41 drives the first drive cam 421 and the second drive cam 423 respectively, which in turn controls the intermittent feeding of the pusher plate 2121 and the intermittent rotation of the conveying ratchet 22 via the first rocker arm 422 and the second rocker arm 424 respectively. In addition, the drive source 41 can also drive the fifth drive cam 425, which in turn drives the fifth rocker arm 426 via the connecting rod 427 to control the caliper 231 on the feeding assembly 23 to intermittently slide the guide pin plate 1 under the bending wheel 31 and the milling wheel 32. Similarly, in the second drive assembly 43, the power from the drive source 41 transmitted by the transmission rod 44 drives the third drive cam 431 and the fourth drive cam 433, which in turn control the translational movement of the slide 33 of the bending and milling mechanism 30 and the clamping action of the second clamping block 353 of the fixing assembly 35 of the bending and milling mechanism 30 via the third rocker arm 432 and the fourth rocker arm 434 respectively.

[0122] It should be noted that, to ensure smooth and accurate transmission, the transmission rod 44 may need to be equipped with auxiliary devices such as bearings and couplings to reduce friction and energy loss. Furthermore, to cope with potential overload or malfunction situations, a safety clutch or overload protection device can be installed in the transmission system.

[0123] It should also be noted that the rotation cycles of the first drive cam 421, the second drive cam 423, and the fifth drive cam 425 in the first drive assembly 42, and the third drive cam 431 and the fourth drive cam 433 in the second drive assembly 43, are all coordinated to ensure that the guide pin 1 is precisely fed and processed at the appropriate time. Therefore, it can be understood that by transmitting the power of a single drive source 41 to both the first drive assembly 42 and the second drive assembly 43 simultaneously via the transmission rod 44, precise control of the feeding mechanism 20 and the milling mechanism 30 is achieved. This design not only simplifies the structure of the drive mechanism 40 but also improves energy transfer efficiency and the overall reliability of the machine.

[0124] Furthermore, in some embodiments of this application, referring to Figures 11 to 13, an adjusting wheel 45 is provided at one end of the transmission rod 44. The adjusting wheel 45 is used to adjust the rotation angle of the transmission rod 44. The adjusting wheel 45 can conveniently adjust the rotation angle of the transmission rod 44, thereby realizing the feeding of the feeding mechanism 20 and the milling mechanism 30 and the fine adjustment of the processing accuracy.

[0125] Specifically, the adjusting wheel 45 is typically tightly engaged with the end of the transmission rod 44 via threads, keyways, or other connection methods to ensure that relative slippage or loosening does not occur during adjustment. The outer edge of the adjusting wheel 45 is usually provided with graduations or markings so that the operator can accurately control and record the rotation angle. In this embodiment, when it is necessary to fine-tune the position or movement of the feeding mechanism 20 or the milling mechanism 30, the operator can change the rotation angle of the transmission rod 44 by rotating the adjusting wheel 45. This adjustment may be for compensating for mechanical wear, calibrating the machining position, or adapting to the machining requirements of guide pins 1 of different specifications. At the same time, the design of the adjusting wheel 45 also considers the convenience and accuracy of operation. Its surface may be made of anti-slip material or designed with anti-slip textures to ensure a good feel and prevent slippage during operation.

[0126] According to the second aspect of this application, the guide pin 1 bending and milling method is applied to the guide pin bending and milling integrated machine of any of the first aspects described above. The guide pin 1 bending and milling method includes the following steps: feeding the guide pin 1, placing the guide pin 1 into one side of the feeding mechanism 20, and the feeding mechanism 20 conveying the guide pin 1 to the bending and milling mechanism 30; bending the guide pin 1, with the bending wheel 31 passing over the protruding structure of the guide pin 1 and bending the structure to one side; milling the guide pin 1, with the milling wheel 32 passing over the protruding structural part of the guide pin 1 and milling the protruding part of the guide pin 1 flat; unloading the guide pin 1, with the feeding mechanism 20 sending the guide pin 1 back from the processing station to the feeding mechanism 20, and the feeding mechanism 20 unloading the processed guide pin 1 to the other side of the feeding mechanism 20.

[0127] Specifically, based on the specific structure of the integrated milling and bending machine for the guide pin sheet provided in the first aspect embodiment above, the milling and bending method for the guide pin sheet 1 is now described in detail as follows:

[0128] Feeding of guide pin 1:

[0129] First, the operator places the guide pin 1 to be processed into the hopper 211 of the feeding mechanism 20. Then, driven by the drive source 41, the feeding mechanism 20, controlled by the first drive cam 421 and the first rocker arm 422 of the first drive assembly 42, uses the pusher plate 2121 on the loading platform 212 to stably and sequentially feed the guide pin 1 into the receiving groove of the conveying ratchet 22 of the feeding mechanism 20. Next, driven by the drive source 41, and controlled by the second drive cam 423 and the second rocker arm 424 of the first drive assembly 42, the feeding mechanism 20 uses the rotation of the conveying ratchet 22 to flip the guide pin 1 in the receiving groove below the milling mechanism 30. Then, driven by the drive source 41, the feeding mechanism 20, controlled by the fifth drive cam 425 and the fifth rocker arm 426 of the first drive assembly 42, pushes the guide pin 1 to the underside of the bending wheel 31 and the milling wheel 32, i.e., the processing position, using the clamp 231 in the feeding assembly 23. Furthermore, driven by the drive source 41, the milling mechanism 30, controlled by the fourth drive cam 433 and the fourth rocker arm 434 of the second drive assembly 43, clamps and fixes the guide pin 1 to the fixing assembly 35 of the milling mechanism 30, awaiting bending and milling by the bending wheel 31 and the milling wheel 32 of the milling mechanism 30, respectively.

[0130] Bending and milling of guide pin 1:

[0131] When the guide pin 1 reaches below the bending wheel 31 and milling wheel 32 of the milling mechanism 30, the slide 33 of the milling mechanism 30, driven by the drive source 41 and controlled by the third drive cam 431 and the third rocker arm 432 of the second drive assembly 43, moves the bending wheel 31 and milling wheel 32 above the protruding structure of the guide pin 1. During the sliding process of the slide 33, the protruding structure of the guide pin 1 is bent and milled according to the sequential positions of the bending wheel 31 and the milling wheel 32. The bending wheel 31 applies downward pressure, bending the protruding structure to one side to achieve a predetermined bending angle and shape. The milling wheel 32, driven by the drive mechanism 40, moves to the protruding part of the guide pin 1 and mills the protruding part of the protruding structure until it is flat.

[0132] Guide pin 1 blanking:

[0133] After bending and milling are completed, the feeding mechanism 20 restarts. First, driven by the drive source 41, and controlled by the fourth drive cam 433 and the fourth rocker arm 434 of the second drive assembly 43, the processed guide pin 1 is released from the fixing assembly 35. Next, driven by the drive source 41, and controlled by the fifth drive cam 425 and the fifth rocker arm 426 of the first drive assembly 42, the feeding mechanism 20 uses the clamp 231 in the feeding assembly 23 to push the guide pin 1 into the receiving groove of the conveying ratchet 22. Then, driven by the drive source 41, and controlled by the second drive cam 423 and the second rocker arm 424 of the first drive assembly 42, the feeding mechanism 20 uses the rotation of the conveying ratchet 22 to flip the guide pin 1 in the receiving groove to one side of the unloading platform 241. Finally, it is collected by the operator.

[0134] Therefore, the milling method for the guide needle sheet 1 according to the embodiments of this application has at least the following beneficial effects: by using the bending wheel 31 and the milling wheel 32 on the milling mechanism 30 to sequentially bend the protruding part of the guide needle sheet 1 and mill the protruding part flat, the guide needle sheet 1 is processed to meet the production requirements of textiles. The integrated setting of bending and milling can avoid repeated feeding of the guide needle sheet 1, and at the same position reference, the guide needle sheet 1 can be bent and milled, thereby avoiding the processing error caused by different references after multiple feedings. Furthermore, it can also avoid the problem that the bent guide needle sheet 1 is not conducive to stacking and is not convenient for further milling processing.

[0135] Furthermore, in some embodiments of this application, multiple bending wheels 31 are provided, and the multiple bending wheels 31 are arranged sequentially at intervals. The axial direction of the multiple bending wheels 31 is perpendicular to the bending direction of the guide needle plate 1. The height of the axial direction of the multiple bending wheels 31 decreases sequentially along the bending direction of the guide needle plate 1. The bending step of the guide needle plate 1 includes the following steps: the protruding part of the guide needle plate 1 passes through the bending wheels 31 arranged at intervals in sequence, and the outer side of the bending wheels 31 abuts against the protruding part of the guide needle plate 1 from high to low in sequence, and bends the protruding part step by step.

[0136] Specifically, in the guide pin milling machine, the bending mechanism is specially designed to include multiple bending wheels 31, which are arranged at intervals. The axial direction of each bending wheel 31 is perpendicular to the bending direction of the guide pin 1. Furthermore, the height of the axes of the multiple bending wheels 31 decreases sequentially along the bending direction of the guide pin 1, forming a stepped arrangement. This allows the protruding portion of the guide pin 1 to pass through these spaced-apart bending wheels 31 in sequence. As the protruding portion passes each bending wheel 31, the outer side of the bending wheel 31 abuts against the protruding portion of the guide pin 1 from high to low, thereby bending the protruding portion step by step.

[0137] The specific implementation steps are as follows: Initial bending: First, the protruding part of the guide needle plate 1 will contact the first bending wheel 31, which is located at its highest position. Under the action of the drive mechanism 40, the first bending wheel 31 will perform an initial bending of the protruding part. Step-by-step bending: Subsequently, the guide needle plate 1 will continue to move forward, and the protruding part will pass through the subsequent bending wheels 31 in sequence. Since the height of these bending wheels 31 decreases sequentially, they will further bend the protruding part step by step until the required bending angle and shape are achieved. Completion of bending: After being processed by all the bending wheels 31, the protruding part of the guide needle plate 1 completes the entire bending process and achieves the predetermined bending effect.

[0138] This design, employing multiple bending wheels 31 for progressive bending, allows for more precise control of the bending process of the guide pin 1, improving bending accuracy and consistency. Furthermore, this design is adaptable to guide pins 1 of varying thicknesses and materials, offering a degree of versatility and flexibility. The aforementioned guide pin 1 bending and milling method, by utilizing multiple bending wheels 31 for progressive bending, achieves efficient and precise bending of the protruding portion of the guide pin 1, further enhancing the processing performance and product quality of the integrated guide pin bending and milling machine.

[0139] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
