Description

Technical Field

[0001] This utility model relates to the field of steering knuckle processing technology, and in particular to an aluminum chassis steering knuckle positioning component and chassis parts processing equipment. Background Technology

[0002] As a core component of the automotive steering system, the aluminum chassis steering knuckle is made of aluminum alloy or aluminum-based composite materials. Its lightweight design significantly reduces the vehicle's unsprung mass, improving acceleration performance, handling agility, and fuel economy. Furthermore, the excellent heat dissipation properties of aluminum alloy extend the component's lifespan.

[0003] Currently, existing aluminum chassis steering knuckle processing equipment typically possesses basic processing functions, but it lacks flexibility in meeting the diverse processing needs of the steering knuckle body. It cannot allow the steering knuckle body to rotate flexibly at different angles and directions, making it difficult to accurately adjust the position and angle according to its shape and changing processing requirements. When faced with complex curved surface processing, drilling and cutting at specific angles, it often falls short, resulting in limited processing range, inconsistent processing quality, and low finished product qualification rate. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, which is that the steering knuckle body cannot flexibly achieve rotation at different angles and directions, resulting in limited processing range, inconsistent processing quality and low finished product qualification rate. Therefore, this utility model proposes an aluminum chassis steering knuckle positioning component and chassis parts processing equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An aluminum chassis steering knuckle positioning assembly includes:

[0007] The system comprises a fixed base and a steering knuckle body. The front side of the fixed base has three grippers that slide in a ring shape. A geared disc is rotatably mounted inside the fixed base. An adjusting head is rotatably mounted on the outer side of the fixed base. A gear is fixedly mounted at one end of the adjusting head inside the fixed base. The gear meshes with the geared disc for transmission. A helical groove is formed on the front side of the geared disc. Helical protrusions are formed on the rear sides of the three grippers. The helical protrusions of the three grippers are all located in the helical groove on the front side of the geared disc. The steering knuckle body can be fixedly clamped by the three grippers.

[0008] A chassis parts processing equipment, comprising:

[0009] A frame, wherein a rotating column is rotatably provided through the side of the frame, and a U-shaped frame is fixedly provided at the front end of the rotating column;

[0010] The U-shaped frame is equipped with an adjustment mechanism, which is used to adjust the position and angle of the steering knuckle body during machining.

[0011] In one possible design, the adjustment mechanism includes the same rotating frame rotatably mounted on both sides of the inner wall of the U-shaped frame. The front side of the rotating frame is rotatably connected to the fixed base. A placement compartment is opened on the top of one side of the U-shaped frame, and a servo motor I is fixedly mounted in the placement compartment. The output shaft of the servo motor I is fixedly connected to one side of the rotating frame. A working compartment is opened on the rear side of the rotating frame, and a servo motor II is fixedly mounted in the working compartment. The output shaft of the servo motor II is fixedly connected to the fixed base.

[0012] In one possible design, a drive motor I is fixedly installed on one side of the top of the frame, and synchronous pulleys are fixedly installed on the outer rear end of both the drive motor I and the rotating column, and the two synchronous pulleys are externally driven by the same synchronous belt.

[0013] In one possible design, a movable frame is slidably mounted on the top of the frame, and a lead screw I is rotatably mounted on the top of the frame below the movable frame. The lead screw I is threadedly connected to the bottom of the movable frame. A drive motor II is fixedly mounted on the rear side of the frame, and the output shaft of the drive motor II is fixedly connected to one end of the lead screw I.

[0014] In one possible design, a mounting base is slidably provided on the inner side of the movable frame, and a lead screw II is rotatably provided inside the movable frame below the mounting base. The lead screw II is threadedly connected to the bottom of the mounting base. A drive motor III is fixedly provided on one side of the movable frame, and the output shaft of the drive motor III is fixedly connected to one end of the lead screw II.

[0015] In this application, when starting to use the equipment, first connect the entire device to the power supply. Then, place the bearing hole of the steering knuckle body between the three jaws on the fixed seat. Next, insert the tool into the adjusting head and rotate it. Since a gear is fixedly installed at one end of the adjusting head inside the fixed seat, and the gear meshes with the rotating gear disk inside the fixed seat, rotating the adjusting head will drive the gear to rotate, which in turn will cause the gear disk to rotate. Since the spiral protrusions on the rear side of the three jaws are all located in the spiral groove on the front side of the gear disk, when the gear disk rotates, the three jaws will slide outward along the annular track on the front side of the fixed seat until they abut against the inner wall of the bearing hole of the steering knuckle body, thereby firmly fixing and clamping the steering knuckle body. After the steering knuckle body is fixed, the processing tools are installed. The processing tools to be used, such as cutting, drilling or grinding tools, are installed on the sliding mounting seat inside the moving frame. After the processing tools are installed, the processing of the steering knuckle body can begin. During the processing, the position of the steering knuckle body and the processing tools needs to be adjusted according to the actual situation.

[0016] To adjust the machining distance between the machining tool and the steering knuckle body, start the drive motor II fixed at the rear of the frame. The output shaft of drive motor II will drive lead screw I to rotate, causing the moving frame to slide on the top of the frame, moving the machining tool on the mounting base closer to or further away from the steering knuckle body to adjust its machining position. To move the machining tool laterally to adjust its machining position, start the drive motor III fixed on one side of the moving frame. The output shaft of drive motor III will drive lead screw II to rotate, causing the mounting base to slide inside the moving frame, thereby moving the machining tool laterally to adjust its machining position.

[0017] When the position of the U-shaped frame needs to be adjusted to change the machining angle of the steering knuckle body, the drive motor I fixed on one side of the top of the frame is started. Since the drive motor I and the rear end of the rotating column are both fixed with synchronous pulleys, and the external transmission sleeves of the two synchronous pulleys are equipped with the same synchronous belt, the drive motor I will drive the rotating column to rotate after starting, and then drive the U-shaped frame to rotate, so as to realize the adjustment of the position of the steering knuckle body by the U-shaped frame.

[0018] When adjusting the position or angle of the steering knuckle body to be machined, servo motor I and servo motor II can be started respectively. When servo motor I is started, its output shaft will drive the rotating frame to rotate on the U-shaped frame, thereby causing the steering knuckle body to shift and adjust its position or angle to be machined. When servo motor II is started, its output shaft will drive the fixed seat to rotate, thereby causing the steering knuckle body to rotate and adjust its position or angle to be machined. By using servo motor I and servo motor II to drive the steering knuckle body to rotate at different angles and directions, the position and angle of the steering knuckle body can be precisely adjusted to meet the machining requirements.

[0019] This utility model has the following beneficial effects:

[0020] This invention, through the setting of an adjustment mechanism, allows the steering knuckle body to flexibly rotate at different angles and directions. This enables operators to adjust the position and angle of the steering knuckle body according to its shape and the varied processing requirements. Whether facing complex curved surface processing or drilling and cutting operations at specific angles, it can easily cope with these tasks, greatly expanding the processing range of the equipment, effectively improving processing quality and finished product qualification rate, and providing a solid guarantee for completing diverse processing tasks efficiently and with high quality.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In one embodiment

[0029] Reference Figure 4-5 An aluminum chassis steering knuckle positioning assembly includes:

[0030] The fixed seat 7 and the steering knuckle body 12 are provided. Three grippers 11 are evenly and uniformly slidably arranged in a ring on the front side of the fixed seat 7. These three grippers 11 can slide along the front side of the fixed seat 7. A geared disc 8 is rotatably installed inside the fixed seat 7. The geared disc 8 can rotate around its own axis within the fixed seat 7. An adjusting head 9 is rotatably embedded in the outside of the fixed seat 7. A gear 10 is fixedly installed at one end of the adjusting head 9 inside the fixed seat 7, and the gear 10 meshes with the geared disc 8 for transmission. When the adjusting head 9 is rotated, the adjusting head 9 drives the gear 10 to rotate, and the gear 10 drives the geared disc 8 to rotate. A spiral groove is opened on the front side of the geared disc 8, and a spiral protrusion is correspondingly provided on the rear side of the three grippers 11. The spiral protrusions of the three grippers 11 are all located in the spiral groove on the front side of the geared disc 8. When the geared disc 8 rotates, through the cooperation of the spiral groove and the spiral protrusion, the three grippers 11 can be driven to slide inward or outward simultaneously, thereby realizing the fixed clamping or releasing operation of the steering knuckle body 12.

[0031] In another embodiment

[0032] Reference Figure 1-4 A chassis parts processing equipment, comprising:

[0033] The frame 1 serves as the supporting structure for the entire equipment. A rotating column 2 is rotatably mounted through the side of the frame 1. The rotating column 2 can rotate around its own axis on the side of the frame 1. A U-shaped frame 3 is fixedly installed at the front end of the rotating column 2. The U-shaped frame 3 rotates as the rotating column 2 rotates.

[0034] An adjustment mechanism is provided on the U-shaped frame 3. This mechanism is used to adjust the position and angle of the steering knuckle body 12 during machining. The adjustment mechanism includes the same rotating frame 4 rotatably mounted on both sides of the inner wall of the U-shaped frame 3. The rotating frame 4 can rotate around its own axis on both sides of the inner wall of the U-shaped frame 3. The rear side of the fixed seat 7 is rotatably connected to the front side of the rotating frame 4, so that the fixed seat 7 can rotate relative to the rotating frame 4. A placement compartment is opened on the top of one side of the U-shaped frame 3. A servo motor I5 is fixedly installed in the placement compartment. The output shaft of the servo motor I5 is fixedly connected to one side of the rotating frame 4. When the servo motor I5 is started, its output shaft drives the rotating frame 4 to rotate, thereby driving the fixed seat 7 and the steering knuckle body 12 to rotate around the axis of the rotating frame 4, realizing the angle adjustment of the steering knuckle body 12. A working compartment is opened on the rear side of the rotating frame 4. Servo motor II6 is fixedly installed, and the output shaft of servo motor II6 is fixedly connected to the fixed base 7. When servo motor II6 starts, its output shaft drives the fixed base 7 to rotate, which in turn drives the steering knuckle body 12 to rotate around the axis of the fixed base 7, further realizing angle adjustment (servo motor I5 and servo motor II6 are both model: ACL60200M4-2500M-24-14-BK. This model of servo motor works in FVC mode through the driver, and uses encoder feedback to detect changes in motor speed and position to achieve zero-speed hovering, i.e., electric shaft locking. When an external force is applied to the motor shaft, the electromagnetic torque generated by the motor can balance the external torque generated by the external force, thereby keeping the motor shaft stationary. This shaft locking method does not require additional mechanical structure and has the characteristics of fast response speed and high locking accuracy).

[0035] To enable the rotation of the rotating column 2, a drive motor I13 is fixedly installed on one side of the top of the frame 1. Both the drive motor I13 and the rear end of the rotating column 2 are fixedly equipped with synchronous pulleys 14. The two synchronous pulleys 14 are externally driven by the same synchronous belt 15. When the drive motor I13 starts, its output shaft drives the synchronous pulley 14 connected to it to rotate. Through the transmission of the synchronous belt 15, the synchronous pulley 14 at the rear end of the rotating column 2 is driven to rotate, thereby causing the rotating column 2 to rotate. Finally, the U-shaped frame 3 and the steering knuckle body 12 are driven to rotate, thus realizing position adjustment.

[0036] In addition, a movable frame 16 is slidably mounted on the top of the frame 1. The movable frame 16 can slide along a specific direction on the top of the frame 1. A lead screw I 17 is rotatably mounted on the top of the frame 1 below the movable frame 16. The lead screw I 17 is threadedly connected to the bottom of the movable frame 16. A drive motor II 18 is fixedly mounted on the rear side of the frame 1. The output shaft of the drive motor II 18 is fixedly connected to one end of the lead screw I 17. When the drive motor II 18 is started, its output shaft drives the lead screw I 17 to rotate. Since the lead screw I 17 is threadedly connected to the movable frame 16, the movable frame 16 is driven to slide on the top of the frame 1, thereby realizing the position movement of the movable frame 16.

[0037] A mounting base 19 is slidably provided on the inner side of the movable frame 16. The mounting base 19 is used to install processing tools (such as cutting, drilling or grinding tools) to meet different processing needs. A lead screw II 21 is rotatably provided inside the movable frame 16 below the mounting base 19. The lead screw II 21 is threadedly connected to the bottom of the mounting base 19. A drive motor III 20 is fixedly provided on one side of the movable frame 16. The output shaft of the drive motor III 20 is fixedly connected to one end of the lead screw II 21. When the drive motor III 20 is started, its output shaft drives the lead screw II 21 to rotate. Since the lead screw II 21 is threadedly connected to the mounting base 19, it drives the mounting base 19 to slide on the inner side of the movable frame 16, thereby moving the position of the mounting base 19 and adjusting the position of the processing tool so as to perform precise processing on the steering knuckle body 12.

[0038] This application can be used in the technical field of aluminum chassis steering knuckle positioning components and chassis parts processing equipment, and can also be used in other fields applicable to this application.

[0039] However, as is well known to those skilled in the art, the working principles and wiring methods of servo motor I5, servo motor II6, drive motor I13, drive motor II18 and drive motor III20 are all conventional methods or common knowledge, and will not be described in detail here.

[0040] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations.
