Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and more specifically, to a tooling for processing steering knuckles. Background Technology

[0002] The steering knuckle, commonly known as the "steering knuckle," is a core connecting component between the steering and driving systems of a vehicle. Widely used in cars, trucks, buses, and other motor vehicles, its structure and performance directly determine the vehicle's steering handling and driving safety. Visually, a steering knuckle is typically an irregularly shaped cast or forged steel part, integrating several key functional components, including the journal for mounting the wheels, the steering arm connecting the steering system, and the lower control arm connecting hole supporting the suspension. Some models also integrate brake caliper mounting brackets or brake drum connecting surfaces. The entire steering knuckle must possess high strength, high rigidity, and good fatigue resistance. The machining of steering knuckles... Tooling is an indispensable auxiliary device in the machining of automotive steering system components. It is mainly used to achieve precise positioning, reliable clamping and stable support of the steering knuckle during the machining process, ensuring machining accuracy (such as hole diameter and flatness) and efficiency. Its components usually include positioning elements (such as positioning pins), clamping elements (such as clamping plates and clamping seats), guiding elements (such as guide rails), clamping bodies (such as bases) and auxiliary support structures. Since the machining of steering knuckles involves multiple processes such as drilling, milling, and grinding, the clamping angle requirements of the steering knuckles are different in different machining steps. Therefore, tooling must have the ability to adjust the angle.

[0003] In related technologies, during the use of steering knuckle machining fixtures, the steering knuckle is generally clamped by moving the clamping plate in the clamping element, and then the clamping plate is positioned by the positioning pin in the positioning element, so that the clamping element clamps and supports the steering knuckle stably, thus enabling its use.

[0004] However, in the current use of steering knuckle machining fixtures, after clamping the steering knuckle with clamping elements, when the steering knuckle needs to be turned for subsequent machining steps, the operator needs to clamp and loosen the steering knuckle to adjust the angle before clamping it again. The entire adjustment process relies on repeated manual operation, making the steering knuckle machining clamping operation cumbersome and inconvenient. Moreover, it can only meet the clamping requirements of a single angle or a few fixed angles. For steering knuckles that are processed in multiple processes and at multiple angles, frequent clamping and loosening operations will significantly increase the working time, and multiple clamping can easily lead to steering knuckle positioning deviation, affecting machining accuracy and the flexibility and adaptability of the fixture's clamping use.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figures 1-4 This utility model provides a technical solution: a steering knuckle processing fixture, including a base 1 and a steering clamping mechanism. A clamping seat 2 is installed on the rear side of the top of the base 1, and a clamping plate 3 is installed on the front side of the top of the base 1. After the clamping seat 2 and the clamping plate 3 clamp the external steering knuckle, the fixture provides a medium for the user to adjust the angle of the workpiece after clamping. This avoids the situation where it is difficult to clamp and adjust the steering knuckle when the clamping seat 2 and the clamping plate 3 are used, thus improving the clamping flexibility and adaptability of the clamping plate 3 and the clamping seat 2.

[0021] Reference Figures 1-4 In a preferred embodiment, the clamping and steering mechanism includes a steering housing 4, which is fixedly connected to the bottom of the clamping seat 2. A steering seat 5, which is fixedly connected to the base 1, is movably connected inside the steering housing 4. A connecting hole 6 is opened inside the steering housing 4, and a connecting seat 7, which is threadedly connected to the steering seat 5, is movably connected inside the connecting hole 6. A steering positioning mechanism is fixedly connected to the bottom left side of the steering seat 5. After the clamping seat 2, in conjunction with the clamping plate 3, clamps the external steering knuckle stably, the steering adjustment operation of the clamped steering knuckle workpiece can be performed through the steering housing 4 in conjunction with the clamping seat 2 and the clamping plate 3. The steering housing 4 rotates around the connecting seat 7, and the connecting seat 7 rotates in opposite directions. The steering mechanism provides a pivot for steering between the steering housing 4 and the steering seat 5. The steering positioning mechanism includes a positioning frame 8, a positioning head 9, and a positioning groove 10. The positioning frame 8 is fixedly connected to the bottom left side of the steering seat 5, and the positioning head 9 is movably connected inside the positioning frame 8. Several positioning grooves 10 are opened on the outer periphery of the steering housing 4. The right side of the positioning head 9 can be inserted into the interior of the positioning groove 10. This provides a medium for the user to position the steering housing 4 and the steering seat 5 after adjustment, so that the user can perform positioning operations between the steering housing 4 and the steering seat 5 after the steering adjustment of the mating clamp 2 and the clamp 3. This improves the convenience of steering positioning of the steering housing 4.

[0022] Reference Figures 2-3In a preferred embodiment, a translation port 11 is provided on the front side of the positioning frame 8. A translation column 12, which is threadedly connected to the positioning head 9, is movably connected inside the translation port 11. This allows for translational connection between the positioning head 9 and the positioning frame 8 to prevent offset, thus preventing the positioning head 9 from detaching from the positioning frame 8 during use. This improves the connection effect between the positioning head 9 and the positioning frame 8. Push grooves 13 are provided on the inner wall of the positioning frame 8 and the left side of the positioning head 9. A spring 14 is provided inside the positioning frame 8. The two ends of the spring 14 are connected to the inner walls of the two push grooves 13, respectively. This can apply a rightward insertion push force to the positioning head 9, preventing the positioning head 9 from easily detaching from the positioning groove 10 during operation. This improves the insertion stability of the positioning head 9. A locking block for matching the positioning groove 10 is provided on the side of the positioning head 9 that is biased towards the positioning groove 10. Preferably, the locking block is trapezoidal in shape.

[0023] Reference Figures 2-3 In a preferred embodiment, an insert frame 15 is fixedly connected to the top left side of the positioning frame 8, and an insert post 16 is magnetically connected inside the insert frame 15. This allows for the insertion and positioning of the positioning head 9 and the positioning frame 8 during operation, preventing the positioning head 9 from being difficult to position and thus improving the working stability of the positioning head 9. A force-receiving port 17 is opened at the bottom left side of the positioning frame 8, and a force-receiving frame 18 fixedly connected to the positioning head 9 is movably connected inside the force-receiving port 17. The bottom of the insert post 16 is inserted into the left side of the top of the force-receiving frame 18, providing a medium for the insert post 16 to apply insertion and positioning force to the positioning head 9. This prevents the insert post 16 from being unable to effectively insert and position the positioning head 9 and the positioning frame 8 during operation, thus improving the insertion and positioning effect of the insert post 16 on the positioning head 9.

[0024] Reference Figure 2 In a preferred embodiment, the clamping plate 3 is movably mounted on the steering shell 4 on the opposite side of the clamping seat 2. Guide openings 19 are provided on both sides of the bottom of the clamping plate 3, and guide rails 20 are movably connected inside the guide openings 19. The bottom of the guide rails 20 is fixedly connected to the top of the steering shell 4, which guides the clamping movement between the clamping plate 3 and the steering shell 4, preventing the clamping plate 3 from shifting during operation and thus improving the working stability of the clamping plate 3. A threaded hole 21 is provided through the clamping plate 3, and a lead screw 22 is threaded inside the threaded hole 21. The rear side of the lead screw 22 is rotatably connected to the front side of the clamping seat 2, and the front end of the lead screw 22 passes through the threaded hole 21 and is connected to a crank rocker arm. This provides a medium for the user to apply clamping force to the clamping plate 3, preventing difficulties in moving and clamping the clamping plate 3 during use, thus improving the ease of operation for moving and clamping the clamping plate 3.

[0025] Specifically, the working process or principle of this steering knuckle machining fixture is as follows: During use, the steering knuckle to be machined and clamped is moved to the top of the steering housing 4, and the workpiece is positioned inside the clamping seat 2 and clamping plate 3. Then, the crank rocker arm on the front side of the lead screw 22 is held to rotate the lead screw 22 in conjunction with the threaded hole 21, applying a rearward threaded thrust to the clamping plate 3. At this time, the guide rail 20 moves inside the guide opening 19, providing a guiding connection between the clamping plate 3 and the steering housing 4, allowing the clamping plate 3 to work in conjunction with the clamping seat 2 to clamp and stabilize the steering knuckle workpiece. The inner side of plate 3 is equipped with a clamping pad, which can clamp and protect the workpiece during clamping and prevent slippage. Then, according to the actual machining angle requirements of the steering knuckle workpiece, rotating the steering housing 4 drives the clamping seat 2 and the clamping plate 3 to rotate, thereby adjusting the steering of the clamped steering knuckle workpiece. When rotation is required, first remove the insert 16 to release the lock of the positioning head 9. Since the locking block on the right side of the positioning head 9 is trapezoidal, as the steering housing 4 rotates, the positioning groove 10 applies a tilting force to the left to the positioning head 9, causing the positioning head 9 to disengage from the positioning groove 10. During this process, the positioning head 9 can flow... After the steering head 9 moves out of the positioning groove 10, the spring 14 contracts under the influence of the moving force of the positioning head 9. After the steering housing 4 drives the clamp 2 and the clamp 3 to adjust the steering of the steering knuckle workpiece, the contracted spring 14 applies a rightward push to the positioning head 9, causing the positioning head 9 to enter the positioning groove 10. This allows for the insertion and pre-positioning of the steering housing 4 and the steering seat 5 after the operation. During this process, the translation column 12 moves with the positioning head 9 inside the translation port 11, guiding the translation between the positioning head 9 and the positioning frame 8. At the same time, the force-bearing frame 18 follows the positioning head 9. Positioning head 9 moves inside force-receiving port 17; when the steering knuckle rotates to the target angle, the steering housing 4 stops rotating; when positioning head 9 enters positioning groove 10 under the influence of spring 14, it indicates that insert post 16 is aligned with the top slot of force-receiving frame 18. Then, insert post 16 can be held and moved downward to insert into the top slot of force-receiving frame 18, so that insert post 16 can perform stable positioning work between positioning head 9 and positioning frame 8 through force-receiving frame 18, so that positioning head 9 cooperates with positioning groove 10 to stably position steering housing 4, ensuring the stability of steering housing 4.
