Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a multi-angle tooling and fixture for a steering knuckle. Background Technology

[0002] The steering knuckle, also known as the "steering knuckle," is a crucial component of the steering axle in automobiles or electric vehicles. Its primary function is to transmit and bear the load from the front of the vehicle, while simultaneously supporting and driving the front wheels to rotate around the kingpin, enabling the vehicle to steer smoothly. During vehicle operation, the steering knuckle must withstand varying impact loads, thus requiring extremely high strength and stability.

[0003] In the machining of steering knuckles, tooling fixtures play a crucial role. They secure the steering knuckle, ensuring its stability during machining and guaranteeing machining accuracy and product quality. However, traditional steering knuckle tooling fixtures have some significant drawbacks. For example, an improperly designed fixture may prevent the steering knuckle from being positioned quickly and accurately during machining, affecting not only machining efficiency but also potentially reducing machining accuracy. Furthermore, traditional fixtures often only allow for single-angle fixation, failing to meet the needs of multi-angle machining, which to some extent limits the machining range and flexibility of the steering knuckle.

[0033] Please see Figure 1-5 This utility model provides a technical solution: a multi-angle tooling fixture for a steering knuckle, including a movable plate 1, a plurality of first fixed seats 3 detachably connected to the top surface of the movable plate 1, a first bearing seat 4 provided on the top surface of the plurality of first fixed seats 3, the first bearing seat 4 being used to position the steering knuckle body 2, the top surfaces of the first fixed seats 3 and the first bearing seat 4 being inclined, a plurality of first hydraulic cylinders 5 adapted to the first fixed seats 3 being installed on the bottom surface of the movable plate 1, a first piston rod 6 being connected to the output direction on the first hydraulic cylinder 5, the end of the first piston rod 6 away from the first hydraulic cylinder 5 penetrating the top surface of the base, the first fixed seat 3 and the second bearing seat 14 being sleeved on the first piston rod 6, and a first limiting component 7 being sleeved on the first piston rod 6;

[0034] Multiple second fixed seats 13 are detachably connected to the bottom surface of the movable plate 1. A second bearing seat 14 is provided on the top surface of the multiple second fixed seats 13. The second bearing seat 14 is used to position the steering knuckle body 2. The top surfaces of the second fixed seats 13 and the second bearing seat 14 are both flat. Multiple second hydraulic cylinders 15 adapted to the second fixed seats 13 are installed on the top surface of the movable plate 1. A second piston rod 16 is connected to the output direction of the second hydraulic cylinder 15. The end of the second piston rod 16 away from the second hydraulic cylinder 15 passes through the bottom surface of the base. The second fixed seats 13 and the second bearing seats 14 are sleeved on the second piston rod 16. A second limiting component 17 is also sleeved on the second piston rod 16.

[0035] In this technical solution, both ends of the movable plate 1 are connected to a rotating mechanism, and the movable plate 1 can rotate with the rotating mechanism. When the movable plate 1 rotates, the multiple second fixed seats 13 that were originally located on its bottom surface will move to the top surface of the movable plate 1.

[0036] When the steering knuckle body 2 needs to be processed, multiple steering knuckle bodies 2 are first sequentially mounted and fixed on multiple first fixed seats 3 and second fixed seats 13. When the steering knuckle body 2 is installed on the first fixed seat 3, the bearing hole on the steering knuckle body 2 is first passed through the first piston rod 6 and assembled onto the bearing seat on the top surface of the first fixed seat 3, ensuring that the bearing hole and the first bearing seat 4 form a release clearance fit. At the same time, the first fixed seat 3 and the first bearing seat 4 are tilted in the same direction. After the steering knuckle body 2 is installed on the first bearing seat 4, it is also tilted, thus exposing all the angles of the multiple parts of the steering knuckle body 2 that need to be processed. Then, the first limiting component 7 is mounted on the first piston rod 6, and the first oil cylinder 5 is activated. The first oil cylinder 5 controls the second piston rod 16 to change from an extended state to a telescopic state. During the retraction of the first piston rod 6, the first limiting component 7 is pressed. Under the combined action of the first limiting component 7 and the first fixed seat 3, the steering knuckle body 2 is clamped and fixed.

[0037] Meanwhile, since different vehicle models require different steering knuckle machining dimensions, the steering knuckle body 2 can be mounted on the second fixed seat 13. By operating the rotating mechanism, the movable plate 1 can rotate, which brings two key changes: the multiple first fixed seats 3 originally located at the top of the movable plate 1 will rotate to the bottom, while the multiple second fixed seats 13 originally located at the bottom will move to the top position. Subsequently, using a similar principle to mounting the steering knuckle body 2 onto the first fixed seat 3, the steering knuckle body 2 can be easily mounted onto the second fixed seat 13. It is worth noting that since the second fixed seat 13 and its matching second bearing seat 14 are both designed to be flat, the steering knuckle body 2 will also be flat after forming a clearance fit with the second bearing seat 14.

[0038] According to the size processing requirements of the steering knuckle body 2, multiple steering knuckle bodies 2 can be installed in batches on multiple first fixed seats 3 and multiple second fixed seats 13. This allows multiple angles that need to be processed on the steering knuckle body 2 to be displayed simultaneously, reducing the number of clamping operations and improving processing accuracy. At the same time, the steering knuckle bodies 2 installed on the first fixed seats 3 and the second fixed seats 13 can be quickly and accurately positioned and clamped and fixed by the first limiting component 7 and the second limiting component 17, respectively.

[0039] In this embodiment: the first limiting component 7 includes a first limiting block 71 and a second limiting block 72. The first limiting block 71 is provided with multiple first pressure rods 75, and the top surface of the first limiting block 71 abuts against the bottom surface of the second limiting block 72.

[0040] The second limiting component 17 includes a third limiting block 171 and a fourth limiting block 172. The third limiting block 171 is provided with multiple second pressure rods 175, and the bottom surface of the third limiting block 171 abuts against the top surface of the fourth limiting block 172.

[0041] During assembly, multiple steering knuckle bodies 2 are first fitted with the first bearing housing 4 and the second bearing housing 14 with clearance. Then, in sequence, the first limiting block 71 and the second limiting block 72 are installed onto the first piston rod 6, while the third limiting block 171 and the fourth limiting block 172 are installed onto the second piston rod 16. Multiple positioning holes are pre-set on the steering knuckle bodies 2 for precise positioning. At this point, the first pressure rod 75 on the first limiting block 71 and the second pressure rod 175 on the third limiting block 171 are precisely inserted into the positioning holes on their respective steering knuckle bodies 2. This design not only allows for quick and accurate positioning of the steering knuckle bodies 2, but also effectively prevents the first limiting block 71 and the third limiting block 171 from loosening through the insertion of the pressure rods, ensuring the overall structural stability.

[0042] In this embodiment: a first limiting rod 73 is provided on the top surface of the first bearing seat 4. One end of the first limiting rod 73 is connected to the top surface of the first bearing seat 4, and the other end extends upward. The first limiting block 71 and the second limiting block 72 are provided with a first limiting hole 74 that is adapted to the first pressure rod 75.

[0043] The top surface of the second bearing seat 14 is provided with a second limiting rod 173. One end of the second limiting rod 173 is connected to the top surface of the second bearing seat 14, and the other end extends downward. The third limiting block 171 and the fourth limiting block 172 are provided with second limiting holes 174 that are adapted to the second pressure rod 175.

[0044] After multiple steering knuckle bodies 2 achieve clearance fit with the first bearing seat 4 and the second bearing seat 14 respectively, in sequence, the first limiting block 71 and the second limiting block 72 are installed on the first piston rod 6, and the third limiting block 171 and the fourth limiting block 172 are installed on the second piston rod 16. During this process, the first limiting holes 74 opened on the first limiting block 71 and the second limiting block 72 pass through the first limiting rod 73 respectively, and the second limiting holes 174 opened on the third limiting block 171 and the fourth limiting block 172 pass through the second limiting rod 173 respectively, so as to achieve the purpose of quickly and accurately positioning the steering knuckle bodies 2.

[0045] In this embodiment: the end of the first piston rod 6 away from the first oil cylinder 5 is connected to a first threaded rod 8, and a first bolt 9 is threaded on the first threaded rod 8;

[0046] The end of the second piston rod 16 away from the second oil cylinder 15 is connected to a second threaded rod 18, and a second bolt 19 is threaded onto the second threaded rod 18.

[0047] In this technical solution, a first through hole is provided on the first limiting block 71, and the diameter of the first through hole is larger than the diameter of the first threaded rod 8 and the first piston rod 6. A second through hole is provided on the second limiting block 72, and the diameter of the second through hole is larger than the diameter of the first threaded rod 8 and smaller than the diameter of the first piston rod 6. An opening communicating with the second through hole is provided on the second limiting block 72, and the diameter of the first bolt 9 is larger than the diameter of the second through hole.

[0048] The third limiting block 171 has a third through hole, and the diameter of the third through hole is larger than the diameter of the second threaded rod 18 and the second piston rod 16. The fourth limiting block 172 has a fourth through hole, the diameter of the fourth through hole is larger than the diameter of the second threaded rod 18 and smaller than the diameter of the second piston rod 16. The fourth limiting block 172 has an opening that communicates with the fourth through hole. The diameter of the second bolt 19 is larger than the diameter of the second through hole.

[0049] After the first limiting hole 74 and the second limiting block 72 are fitted onto the first piston rod 6, the first hydraulic cylinder 5 can be activated. The first hydraulic cylinder 5 controls the first piston rod 6 to change from an extended state to a retracted state. During this process, the first piston rod 6 will synchronously pull the first threaded rod 8 and the first bolt 9 connected to it downwards. This movement will continue until the bottom surface of the first bolt 9 contacts the top surface of the second limiting block 72 and generates a resisting force. At this time, combined with the action of the first fixed seat 3, the upper and lower sides of the steering knuckle body 2 will be firmly clamped and fixed. Subsequently, by operating the rotating mechanism, the movable plate 1 can be rotated, and the second fixed seat 13 on the movable plate 1 changes from facing downwards to facing upwards. Then, the second hydraulic cylinder 15 is activated. The second hydraulic cylinder 15 operates on the same principle as the first hydraulic cylinder 5, thereby clamping and fixing the steering knuckle body 2 onto the second fixed seat 13.

[0050] In this embodiment: the movable plate 1 is provided with a plurality of first threaded holes 10, and the bottom surfaces of the plurality of first fixed seats 3 and the second fixed seats 13 are provided with a plurality of second threaded holes 11 that are adapted to the first threaded holes 10. The plurality of first threaded holes 10 and the second threaded holes 11 are all threaded with a third threaded rod 12.

[0051] After excessive use, the first fixed seat 3, the first bearing seat 4, the second fixed seat 13, and the second bearing seat 14 will wear out. In order to ensure the tightness of the steering knuckle body 2 during the processing, the worn first fixed seat 3, the first bearing seat 4, the second fixed seat 13, and the second bearing seat 14 need to be replaced. This can be done by rotating the third threaded rod 12 to remove it from the first threaded hole 10 and the second threaded hole 11, thereby removing the first fixed seat 3, the first bearing seat 4, the second fixed seat 13, and the second bearing seat 14 from the movable plate 1 for replacement.

[0052] In this embodiment: the top surface of the movable plate 1 is also provided with a plurality of first positioning components 20, and the plurality of first positioning components 20 are respectively adjacent to a plurality of first fixed seats 3;

[0053] The bottom surface of the movable plate 1 is also provided with a plurality of second positioning components 21, and the plurality of second components are adjacent to a plurality of second fixing seats 13 respectively.

[0054] When assembling the steering knuckle body 2, the mounting holes on the steering knuckle body 2, which is mounted on the first fixed seat 3 and the first bearing seat 4, are aligned with the first limiting component 7. Similarly, the mounting holes on the steering knuckle body 2, which is mounted on the second fixed seat 13 and the second bearing seat 14, are aligned with the second limiting component 17. This installation method not only effectively limits the range of motion of the steering knuckle body 2, but also significantly enhances the stable positioning of the steering knuckle body 2 in the device, thereby helping to improve the accuracy of the machining operation.

[0055] In this embodiment: the first positioning component 20 includes a first mounting base 201 and a first positioning rod 202. The first mounting base 201 is mounted on the top surface of the movable plate 1, and the first positioning rod 202 is connected to the top surface of the first mounting base 201. Both the top surface of the first mounting base 201 and the first positioning rod 202 are inclined.

[0056] The second positioning component 21 includes a second mounting base 211 and a second positioning rod 212. The second mounting base 211 is mounted on the top surface of the movable plate 1, and the second positioning rod 212 is connected to the top surface of the second mounting base 211. Both the top surface of the second mounting base 211 and the second positioning rod 212 are inclined.

[0057] When the steering knuckle body 2 is assembled onto the inclined first fixed seat 3 and the first bearing seat 4, it will also adopt an inclined posture accordingly. Simultaneously, the mounting holes on the steering knuckle body 2 will be inclinedly fitted onto the similarly inclined first positioning rod 202. When the steering knuckle body 2 is assembled onto the planar second fixed seat 13 and the second bearing seat 14, it will also adopt a planar posture accordingly. Simultaneously, the mounting holes on the steering knuckle body 2 will be planarly fitted onto the similarly planar second positioning rod 212.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
