In the accompanying drawings, for the sake of clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.
[0042] Combine Figures 1 to 11As shown, according to a specific embodiment of the present application, a processing device is provided, including: a pick-up and delivery mechanism 1, the pick-up and delivery mechanism 1 is connected to the pile driver 8, and a part of the pick-up and delivery mechanism 1 is movably arranged relative to the pile driver 8 along a first direction; a broach actuator 2, the broach actuator 2 is located at the top of the pick-up and delivery mechanism 1, the broach actuator 2 is connected to the pick-up and delivery mechanism 1, the broach actuator 2 has a press-fit position and a broach position, a part of the broach actuator 2 is movably arranged relative to the pick-up and delivery mechanism 1 along the first direction so that the broach actuator 2 moves to the press-fit position and the broach position, and the broach actuator 2 has a bushing mounting portion; a flipping mechanism 3, the flipping mechanism 3 is located at the top of the broach actuator 2, the flipping mechanism 3 is connected to the broach actuator 2, the flipping mechanism 3 has a steering knuckle mounting portion, and the flipping mechanism 3 has a rotational state of rotating the steering knuckle around the first axis.
[0043] By applying the technical solution of the present invention, the pick-up and delivery mechanism 1 and the broaching actuator 2 work in coordination, so that the processing device can realize pressing and broaching without manual handling of the steering knuckle, and the turning mechanism 3 realizes automatic turning of the steering knuckle, eliminating the need for an operator to manually turn the steering knuckle upright and place it in the device, thereby improving the processing efficiency of the processing device.
[0044] The technical solution of this application provides a flexible tooling mechanism and closed-loop detection device to address the aforementioned technical issues. The device enables workpiece flipping, clamping, and transfer. The top of the processing device is a flipping mechanism 3, the center is a sleeve and broach actuator 2, and the bottom is a workpiece transfer mechanism 1 and a buffer mechanism 5. The buffer mechanism 5 effectively reduces vibration during processing, effectively resolving safety hazards, low work efficiency, and waste of manpower associated with prior art operations.
[0045] Furthermore, the first direction is the length direction of the picking and delivering mechanism 1 , and / or the direction of the first axis is parallel to the second direction, and the second direction is the width direction of the picking and delivering mechanism 1 .
[0046] This design allows for more coordinated movement between the pick-up and delivery mechanism 1 and the flipping mechanism 3, improving machining accuracy and efficiency. It's suitable for machining scenarios requiring precise control of workpiece position and angle, such as the automated assembly of precision mechanical parts. In practical applications, this precise coordinate control ensures the knuckle and bushing maintain optimal machining posture during machining, effectively avoiding machining errors and ensuring high product quality.
[0047] The feeding and picking structure can perform two-station processing, with loading and unloading at the first station and workpiece processing at the second station. The first station uses a handheld crane to load and unload materials, which reduces labor loss and avoids safety hazards of manual loading and unloading.
[0048] The movement of the pick-up and delivery mechanism 1 enables rapid transfer of workpieces between different processing locations, improving processing efficiency. This design is suitable for automated production lines for automotive parts such as steering knuckles and bushings, enabling a continuous and efficient processing flow. This design effectively reduces the time and labor costs associated with workpiece handling, significantly improving the automation level and processing efficiency of the production line. This advantage is particularly evident in applications requiring continuous multi-step processing, such as automated steering knuckle assembly lines.
[0049] Further, if Figure 5 As shown, the flipping mechanism 3 includes: a shaft bracket 36, there is at least one shaft bracket 36, the shaft bracket 36 is connected to the broaching actuator 2, and a shaft mounting hole is provided in the shaft bracket 36; a connecting shaft 35, the first end of the connecting shaft 35 is located in the shaft mounting hole, and the first end of the connecting shaft 35 and the shaft bracket 36 are rotatably arranged relative to each other; a flap 38, the flap 38 is connected to the second end of the connecting shaft 35, the flap 38 has a steering knuckle mounting portion, the flap 38 has a loading state parallel to the horizontal plane, and the flap 38 has a pressing state perpendicular to the horizontal plane; wherein, when the flap 38 is in the pressing state and the broaching actuator 2 is in the pressing position, the pile driver 8 performs a pressing operation on the steering knuckle and the bushing.
[0050] The vertical and horizontal switching of flap 38 ensures the correct placement of the steering knuckle during different process steps, improving processing quality and production efficiency. This design is suitable for workpieces that need to be processed at different angles, such as in automated steering knuckle assembly lines. This design of flip mechanism 3 avoids the positioning errors and safety hazards associated with manual workpiece flipping. The increased level of automation makes the processing process smoother, reduces processing time, and increases production line throughput, which translates to higher economic benefits for large-scale manufacturing companies.
[0051] Further, if Figure 5 As shown, there are two shaft frames 36, which are respectively arranged on both sides of the broach actuator 2, and there are two connecting shafts 35, which are arranged in a one-to-one correspondence with the two shaft frames 36. The flap 38 is located between the two connecting shafts 35, and the first end of each connecting shaft 35 is passed through the shaft mounting hole in the corresponding shaft frame 36, and the second end of each connecting shaft 35 is respectively connected to the two sides of the flap 38, so that at least one of the two connecting shafts 35 drives the flap 38 to be rotatable around the first axis.
[0052] The dual-axis frame 36 and dual connecting shaft 35 design ensures more stable rotation of the flap 38, making it suitable for machining applications requiring high-precision rotation, such as automated assembly lines for automotive steering knuckles, ensuring precise alignment during press-fit and broaching. The stable rotation of the dual-axis frame 36 and dual connecting shaft 35 can withstand greater tilting loads, ensuring workpiece stability during the tilting process and avoiding machining errors caused by workpiece sway. This design is particularly suitable for the automated machining of heavy-loaded workpieces, such as large steering knuckles, further expanding the applicability and processing capabilities of the machining device.
[0053] Furthermore, if Figure 4 and Figure 5 As shown, the flipping mechanism 3 also includes: a driving part; a transmission structure, the transmission structure includes a rack 32 and a gear 33, the rack 32 is connected to the broach actuator 2, the gear 33 is mounted on the rack 32 and is arranged to be relatively engaged with the gear 33, the driving part is connected to the rack 32, the driving part is used to drive the rack 32 to move in a first direction to drive the gear 33 to rotate around its own central axis, and the gear 33 is connected to the connecting shaft 35.
[0054] The turning mechanism 3 can automatically turn the workpiece 90 degrees through the gear 33 and the rack 32, avoiding manual turning, improving efficiency and avoiding safety hazards.
[0055] Furthermore, if Figure 6 As shown, the processing device also includes a buffer mechanism 5, which includes at least one of a first buffer structure and a second buffer structure. One end of the first buffer structure is connected to the flipping mechanism 3, and the other end of the first buffer structure is connected to the broach actuator 2. One end of the first buffer structure is connected to the flipping mechanism 3, and the other end of the first buffer structure is connected to the pick-up and delivery mechanism 1.
[0056] The provision of buffer mechanism 5 effectively absorbs and reduces vibration and shock generated during machining, protecting equipment and workpieces, and improving machining stability and precision. This makes it suitable for applications requiring high-precision machining, such as automated assembly lines for precision mechanical parts. This design of buffer mechanism 5 reduces vibration and shock during machining, protecting equipment and workpieces from damage. This is particularly important in the machining of precision parts, significantly improving product dimensional accuracy and surface quality, reducing scrap rates, and lowering production costs.
[0057] Furthermore, at least one of the first buffer structure and the second buffer structure includes a buffer spring 51 , and the axis of the buffer spring 51 is parallel to the vertical direction.
[0058] When the bushing is press-fitted, the buffer spring 51 reduces the rigid collision between the flipping mechanism 3 and the broaching actuator 2, thereby reducing the vibration of the press-fitting device.
[0059] The design of buffer spring 51 ensures that buffer mechanism 5 has a strong vertical cushioning effect, making it suitable for processing scenarios requiring vertical cushioning, such as automated steering knuckle assembly lines, ensuring the stability and safety of the knuckle during press-fitting and broaching operations. The vertical design of buffer spring 51 effectively absorbs vertical impacts, particularly in the automated assembly of heavy-loaded workpieces such as steering knuckles. This prevents damage to equipment and workpieces caused by impact, ensures workpiece stability during processing, and further improves machining accuracy and production efficiency.
[0060] Furthermore, if Figure 3 As shown, the processing device also includes a self-aligning locking mechanism 4, which is connected to the flap 38 so that the self-aligning locking mechanism 4 can rotate around the first axis following the flap 38, and the self-aligning locking mechanism 4 includes: an angle cylinder 45, which is connected to the flap 38; a rotating frame 44, which is connected to the angle cylinder 45, and the angle cylinder 45 has a rotating state of driving the rotating frame 44 to rotate around the second axis, and the second axis is perpendicular to the plane where the flap 38 is located; a self-aligning clamp 46, a first end of the self-aligning clamp 46 is connected to the rotating frame 44, and the second end of the self-aligning clamp 46 is extended away from the rotating frame 44, and the second end of the self-aligning clamp 46 forms an alignment portion for positioning the steering knuckle.
[0061] Since the two forks of the steering knuckle are not at the same height, the self-aligning jaws 46 will automatically align themselves through the pin 47 when clamping, avoiding a gap between the fixture and the workpiece, which would cause the workpiece to vibrate during machining.
[0062] The setting of the self-aligning and locking mechanism 4 enables the steering knuckle to be automatically aligned and locked during the pressing and broaching processes without manual adjustment, thereby improving the degree of automation and precision of the processing. It is suitable for workpieces that require automatic alignment and locking, such as the automated assembly line of automobile steering knuckles, ensuring the precise alignment and stable fixation of the steering knuckle in each process. This innovative design of the self-aligning and locking mechanism 4 realizes the automatic alignment and locking of the workpiece, greatly reducing the intervention of manual operation, and improving the degree of automation and production efficiency of the processing. In particular, in the automated assembly of automobile steering knuckles, this design can ensure the precise alignment of the steering knuckle in different processes, avoid processing errors caused by workpiece position deviation, and has a significant effect on improving product consistency and productivity.
[0063] Furthermore, if Figure 2As shown, the broaching actuator 2 includes a sliding plate 22, which is arranged on the pick-up and delivery mechanism 1. Sliding blocks 21 are provided on both sides of the sliding plate 22. The sliding blocks 21 are used to provide a limit for the sliding plate 22. The sliding plate 22 is movably arranged along a first direction relative to the pick-up and delivery mechanism 1. A broaching cup 26 and a bushing cup 27 are provided on the sliding plate 22. The bushing cup 27 forms a bushing mounting portion, wherein the pile driver 8 has a press-fit working piece. When the broaching actuator 2 is in the press-fit position, the bushing cup 27, the press-fit working piece and the axial hole of the steering knuckle are arranged in a collinear manner. A broaching opening 28 is provided on the pick-up and delivery mechanism 1. When the broaching actuator 2 is in the broaching position, the broaching cup 26 and the broaching opening 28 are arranged relative to each other.
[0064] The design of the sliding plate 22 enables the broaching actuator 2 to move along the first direction on the pick-and-feed mechanism, enabling rapid positioning and switching of the workpiece. This design is suitable for workpieces that need to be processed at different locations, such as in automated steering knuckle assembly lines, ensuring precise alignment and efficient processing of the steering knuckle during the press-fit and broaching processes. The combination of the sliding plate 22 and the sliding block 21 enables rapid positioning and switching of the broaching actuator 2, significantly shortening the processing cycle and improving production efficiency. In automated steering knuckle assembly lines, this design ensures precise alignment of the workpiece between different processes, avoiding processing errors caused by workpiece position deviations, and significantly contributes to improving product quality and productivity.
[0065] The broaching actuator 2 drives the sliding plate 22 through the slide cylinder 23 to exchange the broaching cup 26 and the bushing cup 27, and the bushing waste can also be removed when the sliding plate 22 slides.
[0066] The movable design of the broaching actuator 2 enables the bushing pressing and broaching processes to be completed in the same workstation, reducing the number of workpiece handling times and lowering production costs. It is particularly suitable for situations where multiple processing steps are required, such as the automated assembly line for steering knuckles.
[0067] This design of the broach actuator 2 not only enables rapid switching of the workpiece between different processing positions, but also ensures the stability of the workpiece during the processing through the setting of the bushing mounting portion. It is suitable for occasions requiring high-precision and high-efficiency processing, such as the automated assembly line of automobile steering knuckles and bushings. It improves the flexibility and efficiency of processing, and reduces the position deviation caused by the transportation of the workpiece between different processes, ensuring the processing accuracy. Especially in the manufacture of high-performance automotive parts, it can significantly improve the quality and consistency of products.
[0068] The technical solution of the above embodiment improves the flexibility and efficiency of the automated assembly line. Furthermore, the provision of the bushing mounting portion ensures the stability of the workpiece during processing, avoiding machining errors caused by workpiece shaking, significantly improving product consistency and productivity. In particular, in the automated assembly of steering knuckles and bushings, this design can significantly improve assembly accuracy, reduce scrap rates, and increase production efficiency and economic benefits.
[0069] This processing device realizes the automated pressing and broaching of the steering knuckle and bushing by integrating the pick-up and delivery mechanism 1, the broaching actuator 2, the flipping mechanism 3, and the self-aligning locking mechanism 4, greatly improving production efficiency and processing accuracy. At the same time, by providing a buffer mechanism 5 and a limit frame, the stability and reliability of the equipment are further enhanced, making it suitable for various occasions requiring high-precision and high-efficiency processing, such as automobile manufacturing, mechanical processing and other industries. In addition, the device can also be modularly expanded according to specific needs, such as adding more workstations, adjusting the flipping angle, etc., to adapt to different types of workpieces and processing requirements, showing good adaptability and flexibility. In actual applications, these modular designs and adaptive adjustment capabilities enable the processing device to easily cope with the processing needs of steering knuckles and bushings of different models, which not only improves the utilization rate of the equipment, but also can quickly adapt to market changes, providing manufacturers with great production flexibility and market competitiveness.
[0070] Furthermore, if Figure 4 As shown, the flip mechanism 3 further includes a first limiting frame 34 , which is located on the top of the rack 32 . The first limiting frame 34 is used to limit the rack 32 in the height direction.
[0071] The first limiting frame 34 prevents the turning mechanism 3 from getting stuck due to the up and down bouncing of the rack 32 during movement.
[0072] The provision of the first limit frame 34 can ensure the stability of the rack in the height direction, prevent the rack from shaking during the transmission process, improve the processing accuracy and stability, and is suitable for occasions where high-precision processing is required, such as the automated assembly line for precision mechanical parts, to ensure the precise alignment and stable rotation of the steering knuckle during the pressing and broaching processes. The use of the first limit frame 34 effectively prevents the rack from shaking during the transmission process and ensures the accuracy of the transmission, which is crucial for precision mechanical parts that require high-precision processing. Especially in the automated assembly line for steering knuckles, this design can ensure the stability of the workpiece during rotation, avoid processing errors caused by uneven rotation loads, and improve the reliability and processing accuracy of the processing equipment.
[0073] A first limiter 34 is fixed to the top of the rack 32 to limit the range of motion of the rack 32, preventing damage from overload or loss of control. The limiting action of the first limiter 34 ensures the stability and safety of the flap 38 during the turning process, further improving the overall performance of the processing device.
[0074] In an optional embodiment, the processing device is a flexible tooling mechanism and a closed-loop detection device, including a pick-up and delivery mechanism 1, a broach actuator 2, a flipping mechanism 3, a self-aligning locking mechanism 4, a buffer mechanism 5, a detection mechanism 6, a hydraulic station 7, and a pile driver 8.
[0075] The pick-up and delivery mechanism 1 includes a base plate 11 , a linear bearing 12 , a pick-up and delivery cylinder 13 , a feeding base plate 14 , a cylinder fixing frame 15 , a connecting frame 16 , a second limiting frame, and a first dead stop iron 18 .

[0077] The damping cylinder 24 effectively avoids problems such as structural deformation caused by rigid collision and bolt loosening caused by vibration when the moving part moves quickly to a stop.
[0078] The discharge port 29 is used for press-fitting of the bushing. As an interference fit is adopted, the softer bushing will generate waste materials due to the chip generation during press-fitting. The discharge port will discharge the waste materials to avoid the accumulation of waste materials and cause equipment failure.

[0082] Detection mechanism 6 includes a switch holder 61, a 90-degree detection switch 62, a 0-degree detection switch 63, a bumper 64, a feed-in-place switch 65, a broach detection switch 66, and a slide detection switch. Detection mechanism 6 eliminates the need for a semi-closed-loop detection system based solely on the cylinder stroke in-place switch. By combining the cylinder stroke switch with the motion structure in-place detection switch, a fully closed-loop detection system is achieved to prevent malfunction.
[0083] The operator places the workpiece on the fixture using a handheld crane, the self-aligning and locking mechanism 4 clamps the workpiece, and the flipping mechanism 3 rotates the workpiece 90 degrees. After the switch detects that it is in place, the pick-up and delivery mechanism 1 sends the workpiece to the bottom of the press to press the bushing. After the press is completed, the broaching actuator 2 removes the bushing cup 27 and moves the broaching cup 26 to the top of the broaching mouth 28 to broach the inner diameter of the bushing. After the broaching is completed, the pick-up and delivery mechanism 1 returns the workpiece to the tool clamping station, the flipping mechanism 3 returns to the center, and the self-aligning and locking mechanism 4 releases the workpiece.
[0084] Optionally, the workpiece fixing frame 41 can be replaced according to the actual situation of the workpiece on site.
[0085] Optionally, the broach cup 26 and the bushing cup 27 can be replaced according to the actual workpiece on site.
[0086] Optionally, the self-aligning jaws 46 can be selected and replaced according to actual conditions.
[0087] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
[0088] While ensuring the processing technology, it is possible to reduce the workload of operators through multi-station processing. The broaching actuator 2 reduces the time between the bushing press-fitting and the pushing action by horizontally shifting the broaching cup 26 and the bushing cup 27, thereby improving processing efficiency. The flipping mechanism 3 rotates the workpiece 90 degrees by rotating it, avoiding manual reverse flipping. The buffer mechanism 5 includes a bottoming out rigid collision between the mechanisms, thereby avoiding loosening of the bolts caused by vibration. The detection mechanism 6 includes a function of achieving closed-loop detection through a detection switch to avoid malfunction of the equipment.
[0089] The design of the processing device in this application fully considers operational convenience, efficiency, and safety. The carefully designed transmission and connection mechanisms between the pick-up and delivery mechanism 1, the broach actuator 2, the tilting mechanism 3, the self-aligning and locking mechanism 4, and the buffer mechanism 5 enable efficient and precise press-fitting of the bushing and steering knuckle. In particular, the introduction of the self-aligning and locking mechanism 4 and the buffer mechanism 5 significantly improves the adaptability and stability of the device, reduces operational difficulty, and provides additional safety, making the entire press-fitting process smoother and safer.
[0090] This application introduces a self-aligning locking mechanism 4 and a buffer mechanism 5 by optimizing the mechanical structure design, which significantly improves the degree of automation and processing accuracy of the processing device. The self-aligning clamping jaw 46 of the self-aligning locking mechanism 4 ensures the precise alignment of the steering knuckle before press-fitting, reduces manual intervention, and improves production efficiency. The buffer spring 51 of the buffer mechanism 5 absorbs impact during the flipping and press-fitting process, prevents the workpiece and equipment from being damaged by excessive force, and extends the service life of the equipment. In addition, the transmission structure design of the rack 32 and the gear 33, as well as the coordination of the connecting shaft 35 and the flap 38, achieves smooth and precise control of the flipping mechanism 3, further improving the reliability of the device. Overall, the processing device of the present invention not only improves the efficiency and accuracy of the press-fitting operation, but also enhances the safety of operation and the durability of the equipment, providing a more optimized solution for the press-fitting operation of vehicle steering knuckle bushings.
