[0035] Reference Figures 1 to 3 According to the embodiment of the present invention, the bending and milling integrated mechanism includes: a frame, a bending and milling assembly 20 and a fixing assembly 30. The bending and milling assembly 20 is slidably arranged on the frame through a slide 21. The bending and milling assembly 20 includes a bending wheel 22 and a milling wheel 23. The bending wheel 22 is arranged on one side of the milling wheel 23. The bending wheel 22 and the milling wheel 23 are located on the same plane. The slidable bending wheel 22 and the milling wheel 23 pass through the protruding structure of the needle guide piece 1 to bend and mill the needle guide piece 1 respectively; the fixing assembly 30 is arranged on the frame and is located below the bending wheel 22 and the milling wheel 23. The fixing assembly 30 is used to clamp and fix the needle guide piece 1. The bending wheel 22 and the milling wheel 23 are slidably arranged above the needle guide piece 1. The bending wheel 22 and the milling wheel 23 are used to bend and mill the needle guide piece 1 respectively.

[0036] Specifically, the bending and milling integrated mechanism provided by the embodiment of the present invention includes a frame, a folding and milling assembly 20 and a fixing assembly 30. The frame is the basic part of the entire mechanism, providing a stable working platform and support structure. The design and manufacturing materials of the frame ensure its rigidity and stability to ensure that the frame will not deform or vibrate during high-precision processing, thereby ensuring processing accuracy. The folding and milling assembly 20 is slidably arranged on the frame through a slide 21. The sliding setting enables the folding and milling assembly 20 to be able to move flexibly on the frame to adapt to processing requirements at different positions and angles. The folding and milling assembly 20 includes a bending wheel 22 and a milling wheel 23, both of which are arranged on the same plane, and pass through the raised structure of the guide needle plate 1 by sliding to perform bending and milling operations.

[0037] In specific operation, as shown in the figure, the bending wheel 22 is set to the right of the milling wheel 23, and the bending wheel 22 first contacts the raised structure of the needle guide plate 1 and applies appropriate pressure to cause it to produce the required bending deformation. Subsequently, the milling wheel 23 performs precise milling processing on the raised structure to achieve the required shape and dimensional accuracy. It should be emphasized that if the milling wheel 23 is set to the right of the bending wheel 22, the milling wheel 23 first contacts the raised structure of the needle guide plate 1 and performs precise milling processing on the raised structure to achieve the required shape and dimensional accuracy. Subsequently, the bending wheel 22 then contacts the milled part of the needle guide plate 1 and applies appropriate pressure to the raised structure to cause it to produce the required bending deformation. Therefore, it can be imagined that different relative positions between the bending wheel 22 and the milling wheel 23 can be set according to different processing requirements.

[0038] Furthermore, a fixing assembly 30 is mounted on the machine frame, below the bending wheel 22 and milling wheel 23. Its function is to clamp and secure the slider 1, ensuring its stable position during machining and preventing movement or deflection, thereby ensuring machining accuracy. The design of the fixing assembly 30 takes into account the shape and size of the slider 1, firmly securing it while allowing the bending wheel 22 and milling wheel 23 to slide freely over it.

[0039] In summary, the integrated bending and milling mechanism achieves efficient and high-precision machining of the guide slider 1. In specific applications, parameters such as the position, pressure, and speed of the bending and milling wheels 22 and 23 can be adjusted as needed to accommodate the machining of different types and specifications of guide sliders 1. This integrated bending and milling mechanism not only improves the machining efficiency and precision of the guide slider 1 but also simplifies the machining process and reduces operational complexity, significantly facilitating the production of the guide slider 1.

[0040] The integrated bending and milling mechanism according to the embodiment of the present invention has at least the following beneficial effects: the convex portion of the guide slider 1 that needs to be bent can be bent and the guide slider 1 can be milled by the bending wheel 22 and the milling wheel 23 on the bending and milling assembly 20, so that the shape and required flatness of the guide slider 1 meet the use requirements of the guide slider 1. The integrated bending and milling process can avoid repeated stacking and loading of the guide slider 1, and can also allow the guide slider 1 to be bent and milled under the same position reference, thereby avoiding processing errors caused by different references after multiple loadings. Furthermore, it can also avoid the peculiar shape of the bent guide slider 1 that is not conducive to stacking and making it inconvenient for the guide slider 1 to undergo further milling.

[0041] Reference Figures 1 to 2 In some embodiments of the present invention, the slide 21 includes a slide 211 that slides along a first direction and a second direction. The first direction extends along the axis of the milling wheel 23, and the second direction lies in a horizontal plane and is perpendicular to the first direction. This design allows the bending wheel 22 and the milling wheel 23 to move precisely in multiple dimensions to accommodate different processing requirements and positions.

[0042] Specifically, the first direction extends along the axis of the milling wheel 23, allowing the bending wheel 22 and the milling wheel 23 to move in this axis direction (the front-to-back direction shown in the figure). The operator or automated system can then adjust the position of the bending wheel 22 and the milling wheel 23 based on the size and shape of the slider 1, aligning them with the protrusions on the slider 1 in the front-to-back direction to achieve optimal machining results. For example, if the protrusions on the slider 1 are located on one side of its surface, and the fixing assembly 30 is secured with the protrusions facing upward, the bending wheel 22 and the milling wheel 23 can be adjusted by sliding along the first direction, allowing them to precisely target the protrusions on the slider 1. The second direction lies within the horizontal plane and is perpendicular to the first direction. This allows the bending wheel 22 and the milling wheel 23 to move left and right within the horizontal plane. When the bending wheel 22 and the milling wheel 23 move left and right, machining can be performed on the protrusions on the slider 1.

[0043] In practice, slide 211 achieves high-precision sliding motion through precision transmission mechanical components such as servo motors, guide rails, and sliders. Precise control of the servo motors by a control system allows for fine-tuning of the positions of the bending and milling wheels 22 and 23 to meet diverse processing requirements. Furthermore, the design of slide 211 also takes stability and durability into consideration. The use of high-strength materials and precision manufacturing processes ensures that slide 211 maintains high precision and stability over long-term use.

[0044] In summary, by combining the sliding functions in the first and second directions, the integrated bending and milling mechanism provided by the present invention can flexibly adjust the positions of the bending wheel 22 and the milling wheel 23 in multiple dimensions to accommodate the processing requirements of guide sliders 1 of various shapes and sizes. This not only improves processing efficiency and precision, but also reduces operational difficulty, greatly facilitating the production of guide sliders 1.

[0045] Reference Figures 1 to 3 In some embodiments of the present invention, the folding and milling assembly 20 further includes a driving member 24, which is disposed on the slide 21 and located on one side of the milling wheel 23. The output end of the driving member 24 is connected to the milling wheel 23, and the driving member 24 drives the milling wheel 23 to rotate.

[0046] In a specific implementation, the drive member 24 can be an electric motor, in particular a servo motor or a stepper motor, which can provide a stable and controllable driving force. Of course, hydraulic motors or pneumatic motors can also be used as alternatives, and the specific choice depends on the actual application environment and requirements. The drive member 24 is connected to the milling wheel 23 through an appropriate transmission mechanism (for example, a belt drive, a chain drive, or a direct connection). When the drive member 24 is started, the driving force it generates is transmitted to the milling wheel 23 through the transmission mechanism, causing the milling wheel 23 to rotate at a predetermined speed and direction.

[0047] In general, by adding a driving member 24 and connecting it to the milling wheel 23, the bending and milling integrated mechanism not only realizes the integration of the two functions of bending and milling, but also can accurately control the rotation of the milling wheel 23, thereby greatly improving the flexibility and precision of processing.

[0048] Reference Figures 2 to 3 In some embodiments of the present invention, a plurality of bending wheels 22 are provided, and the plurality of bending wheels 22 are arranged in sequence at intervals. The axial directions of the plurality of bending wheels 22 are parallel to the first direction, and the heights of the axes of the plurality of bending wheels 22 rise or fall in sequence.

[0049] Specifically, the bending wheels 22 are spaced apart to ensure that the guide slider 1 can bend gradually and continuously during its transfer. The axes of the multiple bending wheels 22 are perpendicular to the bending direction of the guide slider 1, enabling them to apply a uniform bending force across the width of the slider 1, thereby ensuring accurate and consistent bending. To further enhance bending flexibility and precision, the axes of the multiple bending wheels 22 are positioned at increasing or decreasing heights. This gradient arrangement allows the guide slider 1 to gradually change its bending angle and direction as it passes through the bending wheels 22 at different heights, achieving gradual and continuous bending. This design not only enhances bending flexibility but also enables the machine to accommodate a wider range of guide slider 1 bending requirements. The gradient arrangement of the multiple bending wheels 22 and their perpendicular axis orientation enable the guide slider 1 bending and milling machine to achieve high-precision and highly flexible bending operations. This design not only improves production efficiency but also significantly expands the machine's application range, enabling it to accommodate a wider range of guide slider 1 processing requirements.

[0050] Further, refer to Figure 2 as well as Figure 3 In some embodiments of the present invention, the bending wheel set 22 formed by multiple bending wheels 22 is height-adjustable. The height of the bending wheel set 22 is adjustable, meaning it can be moved vertically away from or closer to the underlying guide slider 1. This allows the bending wheel set 22 to be moved away from or closer to the raised structure, thereby controlling the bending length of the raised structure and meeting a wider range of guide slider 1 bending requirements. In practice, a lifting mechanism (such as a hydraulic cylinder or electric push rod) can be used to adjust the height of the bending wheel set 22. A controller inputs commands to the lifting mechanism, which precisely adjusts the bending wheel set 22 to a predetermined height. To ensure accurate and stable adjustment, a position sensor and feedback system can be included to monitor the height of the bending wheel set 22 in real time and automatically adjust it. The operator can adjust the height of the bending wheel set 22 based on factors such as the thickness and material of the workpiece and the desired bending angle. This height-adjustable design not only expands the processing range of the mechanism but also makes the processing more flexible and efficient. At the same time, combined with the multi-point bending design of the above embodiment, high-precision and high-efficiency bending processing of the workpiece can be achieved.

[0051] Reference Figure 1 、 Figure 3 as well as Figure 4 In some embodiments of the present invention, the fixing assembly 30 includes a fixing base 31 and a second clamping block 32. The fixing base 31 is disposed on the frame, and a first clamping block 311 is disposed at the upper end of the fixing base 31; the second clamping block 32 is slidably disposed at the upper end of the fixing base 31 and is located on one side of the first clamping block 311. The second clamping block 32 is close to the first clamping block 311 and is used to clamp and fix the needle guide slider 1.

[0052] Specifically, the fixing assembly 30 primarily consists of a fixing base 31, a first clamping block 311, and a second clamping block 32. The fixing base 31 is securely mounted on the frame and serves as the foundation for the entire fixing assembly 30. A first clamping block 311 is provided at the upper end of the fixing base 31. The first clamping block 311 is fixed and cooperates with the second clamping block 32 to clamp the slider 1. It should be noted that a contoured groove (not shown) is provided on the side of the first clamping block 311 facing the second clamping block 32. This contoured groove matches the shape of the slider 1, thereby better securing the slider 1. The second clamping block 32 is slidably mounted on the fixing base 31, located to one side of the first clamping block 311. This allows the second clamping block 32 to move closer to or closer to the first clamping block 311 as needed to accommodate sliders 1 of varying widths and thicknesses. For example, a drive mechanism (not shown) can be used to drive the second clamping block 32 away from or toward the first clamping block 311 to secure the slider 1. When the second clamping block 32 is close to the first clamping block 311, they together form a clamping space for firmly fixing the guide slider 1 to prevent it from moving or deforming during the bending and milling processes. Furthermore, in order to realize the sliding function of the second clamping block 32, the fixed base 31 can be equipped with a structure such as a guide rail or a slide groove, and the second clamping block 32 can be equipped with a matching slider or roller. In addition, a reset member such as a spring, a cylinder, or an electric push rod (not shown in the figure) may also be equipped to drive the sliding reset of the second clamping block 32 to facilitate the clamping operation of the next guide slider 1.

[0053] Reference Figure 3 as well as Figure 4 Furthermore, in some embodiments of the present invention, the fixing assembly 30 also includes a limiting groove 33, which is arranged on one side of the fixing seat 31, and the notch at the upper end of the limiting groove 33 is aligned with the notch between the first clamping block 311 and the second clamping block 32, and the guide needle piece 1 can be inserted into the notch of the limiting groove 33.

[0054] Furthermore, the fixing assembly 30 not only fixes the needle guide piece 1, but also provides precise positioning of the needle guide piece 1 to ensure its position accuracy during the processing. To this end, the fixing assembly 30 is also equipped with a limiting groove 33. The limiting groove 33 is arranged on one side of the fixing seat 31, which can ensure that the needle guide piece 1 can smoothly enter the limiting groove 33 when it is transferred to the fixing assembly 30. The notch of the limiting groove 33 is aligned with the notch between the first clamping block 311 and the second clamping block 32. When the needle guide piece 11 accurately slides into the notch of the limiting groove 33, it can be accurately fed into the square groove between the first clamping block 311 and the second clamping block 32, thereby ensuring the accuracy of the position of the needle guide piece 1 and the smoothness of the transfer. In addition, the needle guide piece 1 can be inserted into the notch of the limiting groove 33. The notch not only plays a role of limiting, but also ensures the stability of the needle guide piece 1 during the processing. When the guide slider 1 is secured between the first clamping block 311 and the second clamping block 32, the retaining groove 33 prevents it from lateral movement during processing, thereby ensuring machining accuracy and quality. The design of the retaining groove 33 not only improves machining accuracy and quality but also reduces scrap rates, providing a strong guarantee for the mass production of the guide slider 1. Furthermore, the retaining groove 33 ensures smooth and accurate movement of the guide slider 1 from transport to securing.

[0055] Reference Figures 1 to 2 In some embodiments of the present invention, a protective cover 231 is provided on the outer periphery of the milling wheel 23. In the integrated bending and milling mechanism, a protective cover 231 is specifically provided on the outer side of the milling wheel 23 to ensure operational safety and prevent flying chips generated during processing. The protective cover 231 is designed to protect the operator from flying chips and ensure a clean processing area, thereby improving the overall working environment quality and operational safety.

[0056] In a specific implementation, the protective cover 231 can be made of metal, plastic or other wear-resistant and impact-resistant materials to ensure its strength and durability. The shape and structure of the protective cover 231 should be designed to adapt to the shape of the milling wheel 23 and be able to completely cover the outer peripheral side of the milling wheel 23 to prevent chips, dust or other impurities from splashing out of the processing area. In order to further improve safety, the protective cover 231 can be designed to be transparent or translucent so that the operator can observe the processing process without opening the protective cover 231. At the same time, appropriate ventilation holes or heat dissipation devices can also be provided on the protective cover 231 to ensure that the heat generated during the processing can be dissipated in time to avoid damage to the mechanism and workpiece caused by excessive temperature. In addition, the installation and removal of the protective cover 231 should be simple and quick to facilitate daily maintenance and cleaning. This goal can be achieved by providing a corresponding quick-release structure on the frame or using standard fasteners.

[0057] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
