In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0042] Combination 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 a 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 broaching actuator 2, the broaching actuator 2 is located at the top of the pick-up and delivery mechanism 1, the broaching actuator 2 is connected to the pick-up and delivery mechanism 1, the broaching actuator 2 has a press-fitting position and a broaching position, a part of the broaching actuator 2 is movably arranged relative to the pick-up and delivery mechanism 1 along the first direction so that the broaching actuator 2 moves to the press-fitting position and the broaching position, and the broaching actuator 2 has a bushing mounting portion; a flipping mechanism 3, the flipping mechanism 3 is located at the top of the broaching actuator 2, the flipping mechanism 3 is connected to the broaching 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 a first axis.

[0043] By applying the technical solution of the present invention, the pick-up and delivery mechanism 1 and the broaching tool actuator 2 work in coordination, so that the processing device can realize pressing and broaching without manual handling of the steering knuckle, and the steering knuckle can be automatically flipped by the flipping mechanism 3, without the need for an operator to manually flip the steering knuckle upright and put it into the device, thereby improving the processing efficiency of the processing device.

[0044] By adopting the technical solution of the present application, a flexible tooling mechanism and a closed-loop detection device are provided to solve the above-mentioned technical problems. The device can realize the flipping, clamping and picking up of the workpiece. The top of the processing device is a flipping mechanism 3, the middle is a pressing sleeve and broaching actuator 2, and the bottom is a workpiece picking up and sending mechanism 1 and a buffer mechanism 5. The buffer mechanism 5 can effectively reduce the vibration of the device during processing, effectively solving the safety hazards, low work efficiency and waste of manpower in the prior art.

[0045] Further, 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 makes the movements of the pick-up and delivery mechanism 1 and the flip mechanism 3 more coordinated, improves the processing accuracy and efficiency, and is suitable for processing scenarios that require precise control of the position and angle of the workpiece, such as the automated assembly of precision mechanical parts. In practical applications, this precise coordinate control can ensure that the knuckle and bushing always maintain the best processing posture during the processing, effectively avoiding processing errors and ensuring the high quality of the product.

[0047] The feeding and picking structure can carry out 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] By moving the pick-up and delivery mechanism 1, the workpiece can be quickly transferred between different processing positions, improving the processing efficiency, and is suitable for the automated production line of automotive parts such as steering knuckles and bushings to achieve a continuous and efficient processing flow. This design of the pick-up and delivery mechanism effectively reduces the time and labor costs of workpiece handling, greatly improves the automation level and processing efficiency of the production line, especially in situations where multiple processes need to be processed continuously, such as the automated assembly line of steering knuckles, the advantages are more obvious.

[0049] Furthermore, if Figure 5 As shown, the flipping mechanism 3 includes: an axle frame 36, at least one axle frame 36 is connected to the broaching tool actuator 2, and axle frame 36 has an axle mounting hole; a connecting shaft 35, a first end of the connecting shaft 35 is located in the axle mounting hole, and the first end of the connecting shaft 35 and the axle frame 36 are relatively rotatable; 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 tool 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 state switching of the flap 38 can ensure the correct placement of the steering knuckle in different processes, improve the processing quality and production efficiency, and is suitable for workpieces that need to be processed at different angles, such as the automated assembly line of the steering knuckle. The design of this flip mechanism 3 avoids the positioning error and safety hazards caused by manual flipping of the workpiece. The improvement of the degree of automation makes the processing process smoother, while reducing the processing time and increasing the throughput of the production line, which means higher economic benefits for large manufacturing companies.

[0051] Furthermore, 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 one-to-one 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 inserted into 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 rotatably arranged around the first axis.

[0052] The design of the double-axis frame 36 and the double connecting shaft 35 makes the rotation of the flap 38 more stable, which is suitable for processing scenarios that require high-precision rotation, such as the automated assembly line of automobile steering knuckles, to ensure the precise alignment of the steering knuckles during the press-fitting and broaching processes. The stable rotation design of the double-axis frame 36 and the double connecting shaft 35 can withstand a larger flipping load, ensure the stability of the workpiece during the flipping process, and avoid processing errors caused by the shaking of the workpiece. It is particularly suitable for the automated processing of heavy-loaded workpieces, such as the manufacture of large steering knuckles, further improving the scope of application and processing capabilities of the processing device.

[0053] Furthermore, if Figure 4 and Figure 5 As shown, the flipping mechanism 3 also includes: a driving unit; 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 meshed with the gear 33, the driving unit is connected to the rack 32, the driving unit 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, thus 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 setting of the buffer mechanism 5 can effectively absorb and reduce the vibration and impact generated during the processing, protect the equipment and workpiece, improve the stability and accuracy of the processing, and is suitable for occasions where high-precision processing is required, such as the automated assembly line of precision mechanical parts. This design of the buffer mechanism 5 reduces the vibration and impact during the processing, protects the equipment and workpiece from damage, which is particularly important in the processing of precision parts, and can significantly improve the dimensional accuracy and surface quality of the product, reduce the scrap rate, and reduce production costs.

[0057] Further, 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 the buffer spring 51 enables the buffer mechanism 5 to have a good buffering effect in the vertical direction, and is suitable for processing scenarios that require buffering in the vertical direction, such as the automated assembly line of the steering knuckle, to ensure the stability and safety of the steering knuckle during the press-fitting and broaching processes. The vertical design of the buffer spring 51 can effectively absorb impacts in the vertical direction, especially in the automated assembly of heavy-loaded workpieces such as the steering knuckle, to avoid damage to equipment and workpieces caused by impacts, ensure the stability of the workpiece during processing, and further improve processing 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, so as to avoid a gap between the fixture and the workpiece and vibration of the workpiece during processing.

[0062] The setting of the self-aligning locking mechanism 4 enables the steering knuckle to be automatically aligned and locked in the pressing and broaching process without manual adjustment, thereby improving the automation and precision of the processing. It is suitable for workpieces that need automatic alignment and locking, such as the automated assembly line of automobile steering knuckles, to ensure the precise alignment and stable fixation of the steering knuckle in each process. This innovative design of the self-aligning locking mechanism 4 realizes the automatic alignment and locking of the workpiece, greatly reduces the intervention of manual operation, and improves the automation and production efficiency of the processing. Especially in the automated assembly of automobile steering knuckles, this design can ensure the precise alignment of the steering knuckle in different processes, avoid the processing error caused by the position deviation of the workpiece, and has a significant effect on improving the consistency and productivity of the product.

[0063] Furthermore, if Figure 2As shown, the broach actuator 2 includes a sliding plate 22, which is arranged on the pick-up and delivery mechanism 1. Sliding blocks 21 are arranged 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 broach cup 26 and a bushing cup 27 are arranged 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 broach actuator 2 is located at 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 colinear manner. A broach opening 28 is provided on the pick-up and delivery mechanism 1. When the broach actuator 2 is located at the broach position, the broach cup 26 and the broach 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-up and delivery mechanism, thereby realizing rapid positioning and switching of the workpiece. This design is suitable for workpieces that need to be processed at different positions, such as the automated assembly line of steering knuckles, to ensure accurate positioning and efficient processing of the steering knuckles during the pressing and broaching processes. The cooperation between the sliding plate 22 and the sliding block 21 realizes rapid positioning and switching of the broaching actuator 2, greatly shortening the processing cycle and improving production efficiency. Especially in the automated assembly line of steering knuckles, this design can ensure accurate positioning of the workpiece between different processes, avoiding processing errors caused by workpiece position deviations, and plays a significant role in improving product quality and productivity.

[0065] The broaching tool actuator 2 drives the sliding plate 22 through the slide plate cylinder 23 to exchange the broaching tool 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 press-fitting and broaching processes to be completed in the same station, 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 realizes the 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, and also ensures the stability of the workpiece during processing by setting the bushing installation part, avoiding processing errors caused by the shaking of the workpiece, and has a significant effect on improving the consistency and productivity of the product. In particular, in the automated assembly of the steering knuckle and the bushing, this design can significantly improve the assembly accuracy, reduce the scrap rate, and improve the 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, which greatly improves the production efficiency and processing accuracy. At the same time, by setting the buffer mechanism 5 and the limit frame, the stability and reliability of the equipment are further enhanced, and it is 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 practical applications, these modular designs and adaptive adjustment capabilities enable the processing device to easily cope with the processing requirements 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 , and 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 setting 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 that require high-precision processing, such as the automated assembly line of 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 avoids the shaking of the rack 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 of the steering knuckle, this design can ensure the stability of the workpiece during the rotation process, avoid processing errors caused by uneven rotation loads, and improve the reliability and processing accuracy of the processing device.

[0073] The first limit frame 34 is fixed on the top of the rack 32 to limit the range of motion of the rack 32 to prevent damage caused by overload or loss of control. The limiting effect of the first limit frame 34 ensures the stability and safety of the flap 38 during the flipping 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 comprises 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 .

[0076] The broach actuator 2 comprises a sliding block 21 , a sliding plate 22 , a slide plate cylinder 23 , a damping cylinder 24 , a second dead stop iron 25 , a broach cup 26 , a bushing cup 27 , a broach opening 28 , and a discharge opening 29 .

[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. Therefore, due to the interference fit, the softer bushing will produce waste due to the chip generation during press-fitting. The discharge port will discharge the waste to avoid the accumulation of waste and cause equipment failure.

The detection mechanism 6 avoids the semi-closed loop detection of only the cylinder stroke in-place switch, and achieves a full closed loop detection by combining the cylinder stroke switch with the motion structure in-place detection switch to prevent the equipment from malfunctioning.

[0083] The operator places the workpiece on the fixture by means of a handheld crane, the self-aligning and locking mechanism 4 clamps the workpiece, the flipping mechanism 3 rotates the workpiece 90 degrees, and after the switch detects that it is in place, the pick-up and delivery mechanism 1 delivers the workpiece to the bottom of the press to press-fit the bushing. After the press-fitting is completed, the broaching actuator 2 removes the bushing cup 27 and moves the broaching cup 26 above the broaching opening 28 to perform broaching on 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 flips it, 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] It can be achieved by multi-station processing while ensuring the processing technology, reducing the workload of operators. The broaching tool actuator 2 reduces the time between the bushing press-fitting and the pushing tool actions by horizontally shifting the broaching tool cup 26 and the bushing cup 27, thereby improving the processing efficiency. The flipping mechanism 3 rotates the workpiece 90 degrees by rotation, thereby avoiding reverse flipping by manpower. The buffer mechanism 5 includes a rigid collision between the mechanisms to avoid loosening of the bolts caused by vibration. The detection mechanism 6 includes a function of reaching a closed-loop detection through a detection switch to avoid malfunction of the equipment.

[0089] The processing device of the present application is designed with full consideration of the convenience, efficiency and safety of operation. The pick-up and delivery mechanism 1, the broach actuator 2, the flip mechanism 3, the self-aligning locking mechanism 4 and the buffer mechanism 5 are connected through a carefully designed transmission and connection mechanism, so as to realize the efficient and accurate press-fitting of the bushing and the steering knuckle. In particular, the introduction of the self-aligning locking mechanism 4 and the buffer mechanism 5 greatly improves the adaptability and stability of the device, reduces the difficulty of operation, and also provides additional safety protection, making the entire press-fitting process smoother and safer.

[0090] The present application introduces a self-aligning locking mechanism 4 and a buffer mechanism 5 by optimizing the mechanical structure design, which significantly improves the automation level and processing accuracy of the processing device. The self-aligning clamping claw 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 the impact during the flipping and press-fitting process, prevents the workpiece and equipment from being damaged due to excessive force, and prolongs 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, realize the smooth and precise control of the flipping mechanism 3, and further improve 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 the vehicle steering knuckle bushing.
