[0027] See also Figure 1-5 The present invention provides a technical solution: a multi-angle processing tool for automobile steering knuckles, comprising a base 1 and a movable plate 5, the top surfaces of the base 1 are connected with numerical control indexing plates 2 at opposite ends, the top surfaces of the two numerical control indexing plates 2 are installed with supporting seats 3 at opposite surfaces, the numerical control indexing plates 2 and the supporting seats 3 are connected through a rotating shaft, one end of the rotating shaft is connected to the inner hole of the output plate of the numerical control indexing plate 2, and the other end is fixedly connected to the supporting seat, the opposite surfaces of the two supporting seats 3 are installed with connecting plates 4, and the two ends of the movable plate 5 are detachably connected to the two connecting plates 4 respectively; The top surface of the movable plate 5 is detachably connected with a plurality of first support seats 10, and the top surfaces of the plurality of first support seats 10 are provided with a first bearing seat 11, and the first bearing seat 11 is used to position the steering knuckle 9. The top surfaces of the first support seat 10 and the first bearing seat 11 are both inclined, and the bottom surface of the movable plate 5 is installed with a plurality of first oil cylinders 12 adapted to the first support seat 10, and the output direction of the first oil cylinder 12 is connected with a first piston rod 13, and one end of the first piston rod 13 away from the first oil cylinder 12 passes through the top surface of the base 1, and the first support seat 10 and the second bearing seat 21 are sleeved on the first piston rod 13, and the first piston rod 13 is also sleeved with a first limit assembly 14; The bottom surface of the movable plate 5 is detachably connected to multiple second support seats 20, and the top surfaces of the multiple second support seats 20 are provided with second bearing seats 21. The second bearing seat 21 is used to position the steering knuckle 9. The top surfaces of the second support seats 20 and the second bearing seats 21 are both planar. The top surface of the movable plate 5 is equipped with multiple second cylinders 22 that are compatible with the second support seats 20. The output direction of the second cylinder 22 is connected to the second piston rod 23, and the end of the second piston rod 23 away from the second cylinder 22 passes through the bottom surface of the base 1. The second support seat 20 and the second bearing seat 21 are sleeved on the second piston rod 23, and the second piston rod 23 is also sleeved with a second limit assembly 24.

[0028] When the steering knuckle 9 needs to be processed, firstly, multiple steering knuckles 9 are sequentially sleeved and fixed on multiple first support seats 10 and second support seats 20. When the steering knuckle 9 is installed on the first support seat 10, firstly, the bearing hole on the steering knuckle 9 is passed through the first piston rod 13 and assembled to the bearing seat on the top surface of the first support seat 10 to ensure that the bearing hole and the first bearing seat 11 form a released clearance fit. At the same time, the first support seat 10 and the first bearing seat 11 are inclined in the same direction. After the steering knuckle 9 is installed on the first bearing seat 11, it is also inclined, so that the angles of multiple parts of the steering knuckle 9 that need to be processed are fully exposed. Then, the first limiting assembly 14 is sleeved on the first piston rod 13, and the first oil cylinder 12 is started. The first oil cylinder 12 controls the second piston rod 23 to change from an extended state to a telescopic state. During the contraction of the first piston rod 13, the first limiting assembly 14 is pressed. Under the joint action of the first limiting assembly 14 and the first support seat 10, the steering knuckle 9 is clamped and fixed; At the same time, since the processing size requirements of the steering knuckle 9 required by different models are different, the steering knuckle 9 can be installed on the second support seat 20. By operating the CNC indexing plate 2, the CNC indexing plate 2 can drive the rotating shaft to rotate, and the rotating shaft drives the supporting seat 3 and the connecting plate 4 to rotate synchronously. The supporting seat 3 and the connecting plate 4 drive the movable plate 5 to rotate. This action will bring about two key changes: the multiple first supporting seats 10 originally placed on the top of the movable plate 5 will rotate to the bottom, and the multiple second supporting seats 20 originally at the bottom will move to the top position. Subsequently, the steering knuckle 9 can be easily installed on the second supporting seat 20 using a principle similar to that of installing the steering knuckle 9 on the first supporting seat 10. It is worth noting that since the second supporting seat 20 and its matching second bearing seat 21 are both designed to be planar, the steering knuckle 9 will also present a planar state after forming a clearance fit with the second bearing seat 21.

[0029] Among them, the staff can install the steering knuckle 9 to be processed on two different forms of mounting seats according to the processing size requirements: one is the inclined first support seat 10 and the first bearing seat 11, and the other is the horizontally arranged second support seat 20 and the second bearing seat 21, and the first limit assembly 14 and the second limit assembly 24 can ensure that the steering knuckle 9 is accurately positioned on the first bearing seat 11 or the second bearing seat 21, thereby improving the processing accuracy of the steering knuckle 9. In addition, when the steering knuckle 9 is installed on the inclined first support seat 10 and the bearing seat, multiple angles on the steering knuckle 9 that need to be processed can be exposed at the same time, thereby reducing the number of clamping times of the steering knuckle 9 during the processing process, thereby improving the processing efficiency; The CNC indexing plate 2 can control the rotation of the movable plate 5 to achieve the position exchange of multiple steering knuckles 9 installed on the top and bottom of the movable plate 5. This function greatly facilitates the processing of the steering knuckle 9 by the processing equipment, making the entire processing process smoother and more efficient, meeting the requirements of different processing sizes, and significantly improving the processing efficiency and convenience.

[0030] In this embodiment: a plurality of first threaded holes 6 are provided on the bottom surfaces of the two connecting plates 4, a plurality of second threaded holes 7 corresponding to the first threaded holes 6 are provided at both ends of the movable plate 5, the second threaded holes 7 penetrate the movable plate 5 longitudinally, and the first threaded holes 6 and the second threaded holes 7 are matched and fixed to each other in a threaded connection manner through a first threaded rod 8.

[0031] During the processing, since the steering knuckles 9 used in vehicles of different brands and models have different specifications, it is necessary to match the first support seat 10 and the second support seat 20 of the corresponding specifications on the movable plate 5 for the processing requirements of each steering knuckle 9. In order to achieve this matching, when the specifications and models of the steering knuckle 9 need to be replaced, we also need to replace the movable plate 5 accordingly. In the specific operation, the first threaded rod 8 can be easily unscrewed from the original first threaded hole 6 and the second threaded hole 7 by rotating it, so as to remove the current movable plate 5. Subsequently, a new movable plate 5 matching the specifications of the new steering knuckle 9 is installed, and the first threaded rod 8 is rotated again to thread it back into the first threaded hole 6 and the second threaded hole 7, thereby completing the entire replacement process. The need to prepare a complete set of positioning tooling for each specification of the steering knuckle 9 is avoided, effectively reducing the production cost.

[0032] In this embodiment: the first limiting assembly 14 includes a first limiting block 141 and a second limiting block 142, a plurality of first pressing rods 145 are arranged on the first limiting block 141, and the top surface of the first limiting block 141 is in conflict with the bottom surface of the second limiting block 142; The second limiting assembly 24 includes a third limiting block 241 and a fourth limiting block 242 . A plurality of second pressing rods 245 are disposed on the third limiting block 241 . The bottom surface of the third limiting block 241 abuts against the top surface of the fourth limiting block 242 .

[0033] During the assembly process, firstly, the multiple steering knuckles 9 are clearance-matched with the first bearing seat 11 or the second bearing seat 21, and then the first limit block 141 and the second limit block 142 are installed on the first piston rod 13, or the third limit block 241 and the fourth limit block 242 are installed on the second piston rod 23. The steering knuckle 9 is preset with multiple positioning holes. At this time, the first pressure rod 145 equipped with the first limit block 141 and the second pressure rod 245 equipped with the third limit block 241 will be accurately inserted into the positioning holes on the matching steering knuckle 9. This design not only enables the steering knuckle 9 to be positioned quickly and accurately, but also effectively prevents the first limit block 141 and the third limit block 241 from loosening through the insertion of the pressure rod, thereby ensuring the stability of the overall structure.

[0034] In this embodiment: a first limiting rod 143 is disposed on the top surface of the first bearing seat 11, one end of the first limiting rod 143 is connected to the top surface of the first bearing seat 11, and the other end extends upward, and a first limiting hole 144 adapted to the first pressing rod 145 is opened on the first limiting block 141 and the second limiting block 142; A second limiting rod 243 is provided on the top surface of the second bearing seat 21 , one end of the second limiting rod 243 is connected to the top surface of the second bearing seat 21 , and the other end extends downward. A second limiting hole 244 adapted to the second pressure rod 245 is opened on the third limiting block 241 and the fourth limiting block 242 .

[0035] After multiple steering knuckles 9 are respectively clearance-matched with the first bearing seat 11 and the second bearing seat 21, in the process of installing the first limit block 141 and the second limit block 142 on the first piston rod 13 and installing the third limit block 241 and the fourth limit block 242 on the second piston rod 23 in sequence, the first limit holes 144 opened on the first limit block 141 and the second limit block 142 respectively pass through the first limit rod 143, and the second limit holes 244 opened on the third limit block 241 and the fourth limit block 242 respectively pass through the second limit rod 243, so as to achieve the purpose of quickly and accurately positioning the steering knuckle 9.

[0036] In this embodiment: the end of the first piston rod 13 away from the first oil cylinder 12 is connected to the first adjusting rod 15, and the first adjusting rod 15 is threadedly sleeved with a first bolt 16; One end of the second piston rod 23 away from the second oil cylinder 22 is connected to a second adjusting rod 25 , and a second bolt 26 is threadedly sleeved on the second adjusting rod 25 .

[0037] In the technical solution, a first through hole is provided on the first limit block 141, and the diameter of the first through hole is larger than the diameter of the first adjusting rod 15 and the first piston rod 13, a second through hole is provided on the second limit block 142, the diameter of the second through hole is larger than the diameter of the first adjusting rod 15 and smaller than the diameter of the first piston rod 13, an opening communicating with the second through hole is provided on the second limit block 142, and the first bolt 16 is larger than the diameter of the second through hole; The third limit block 241 is provided with a third through hole, and the diameter of the third through hole is larger than the diameters of the second adjusting rod 25 and the second piston rod 23. The fourth limit block 242 is provided with a fourth through hole, and the diameter of the fourth through hole is larger than the diameter of the second adjusting rod 25 and smaller than the diameter of the second piston rod 23. The fourth limit block 242 is provided with an opening connected to the fourth through hole, and the diameter of the second bolt 26 is larger than the diameter of the second through hole. After the first limiting hole 144 and the second limiting block 142 are sleeved on the first piston rod 13, the first oil cylinder 12 can be started, and the first oil cylinder 12 controls the first piston rod 13 to change from an extended state to a contracted state. During this process, the first piston rod 13 will synchronously pull the first threaded rod 8 and the first bolt 16 connected thereto to move downward together, and this movement will continue until the bottom surface of the first bolt 16 contacts the top surface of the second limiting block 142 and generates a resistance force. At this time, combined with the action of the first support seat 10, the upper and lower sides of the steering knuckle 9 will be firmly clamped and fixed. Subsequently, by operating the rotating mechanism, the movable plate 5 can be rotated, so that the second support seat 20 on the movable plate 5 changes from downward to upward, and then the second oil cylinder 22 is started. The second oil cylinder 22 is the same as the first oil cylinder 12 in the same principle of starting, so that the steering knuckle 9 is clamped and fixed on the second support seat 20.

[0038] In this embodiment: a plurality of third threaded holes 17 are provided on the movable plate 5, a plurality of fourth threaded holes 18 matching the third threaded holes 17 are provided on the bottom surfaces of the plurality of first support seats 10 and the second support seats 20, and a second threaded rod 19 is threadedly connected in the plurality of third threaded holes 17 and the fourth threaded holes 18.

[0039] After being used too many times, the first support seat 10, the first bearing seat 11, the second support seat 20 and the second bearing seat 21 will be worn. In order to ensure the tightening state of the steering knuckle 9 during the processing, it is necessary to replace the worn first support seat 10, the first bearing seat 11, the second support seat 20 and the second bearing seat 21. The third threaded rod can be rotated to remove the second threaded rod 19 from the third threaded hole 17 and the fourth threaded hole 18, so that the first support seat 10, the first bearing seat 11, the second support seat 20 and the second bearing seat 21 can be removed from the movable plate 5 for replacement.

[0040] In this embodiment: a plurality of first positioning components 27 are further disposed on the top surface of the movable plate 5 , and the plurality of first positioning components 27 are respectively adjacent to the plurality of first supporting seats 10 .

[0041] When the steering knuckle 9 is assembled to the first support seat 10 and the first bearing seat 11, the mounting hole on the steering knuckle 9 mounted on the first support seat 10 and the first bearing seat 11 is aligned with the first limit assembly 14, which not only effectively limits the range of motion of the steering knuckle 9, but also significantly enhances the stable positioning of the steering knuckle 9 in the device, thereby helping to improve the accuracy of the processing operation.

[0042] In this embodiment: the first positioning assembly 27 includes a first mounting seat 271 and a first positioning rod 272. The first mounting seat 271 is mounted on the top surface of the movable plate 5, and the first positioning rod 272 is connected to the first mounting seat on the top surface. The top surface of the first mounting seat 271 and the first positioning rod 272 are both inclined.

[0043] When the steering knuckle 9 is assembled on the first support seat 10 and the first bearing seat 11 in an inclined shape, it itself will also present an inclined posture accordingly. At the same time, the mounting hole on the steering knuckle 9 will also be sleeved on the first positioning rod 272 which is also inclined in an inclined manner.

[0044] In this embodiment: a plurality of second positioning components 28 are further disposed on the bottom surface of the movable plate 5 , and the plurality of second components are adjacent to the plurality of second supporting seats 20 respectively.

[0045] When the steering knuckle 9 is assembled to the second support seat 20 and the second bearing seat 21, the mounting hole on the steering knuckle 9 mounted on the second support seat 20 and the second bearing seat 21 is aligned with the second limiting assembly 24, which not only effectively limits the range of motion of the steering knuckle 9, but also significantly enhances the stable positioning of the steering knuckle 9 in the device, thereby helping to improve the accuracy of the processing operation.

[0046] In this embodiment: the second positioning assembly 28 includes a second mounting seat 281 and a second positioning rod 282. The second mounting seat 281 is mounted on the top surface of the movable plate 5, and the second positioning rod 282 is connected to the second mounting seat on the top surface. The top surface of the second mounting seat 281 and the second positioning rod 282 are both inclined.

[0047] When the steering knuckle 9 is assembled to the second support seat 20 and the second bearing seat 21 in a planar shape, it itself will also present a planar posture accordingly. At the same time, the mounting hole on the steering knuckle 9 will also be sleeved on the first positioning rod 272 that is equally inclined in a planar manner.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
