Description

Technical Field

[0001] This application relates to the field of steering knuckle machining equipment technology, and more specifically, to tooling for machining the center hole of a steering knuckle. Background Technology

[0002] As the core load-bearing component of the automotive steering system, the machining accuracy of the steering knuckle directly determines the vehicle's driving safety and handling stability. The center hole, as the reference positioning element for subsequent multi-process machining of the steering knuckle, is a prerequisite for ensuring the machining accuracy of key parts such as the lever and fork lug. Therefore, the performance of the center hole machining tooling plays a decisive role in the overall production quality of the steering knuckle.

[0003] In related technologies, to prevent phenomena such as misalignment, uneven allowance, and warping of the disc in the forged blank, for example, the patent with publication number CN201807915U provides a machining fixture for the center hole of the vertical forging steering knuckle. This machining fixture uses both the V-block on the rod and the V-block on the ear to simultaneously center the vertical forging steering knuckle. For vertical forging steering knuckles with misalignment, it balances the center of the fork ear and the shaft end, ensuring both the machining allowance of the rod and the machining allowance of the fork ear end. The effect is more obvious for some larger vertical forging steering knuckles that are difficult to form, greatly reducing the scrap rate. Moreover, the structure is simple and easy to manufacture and adjust.

[0004] Although the existing technical solutions mentioned above can center the steering knuckle by setting V-blocks, the tooling compatibility is poor. The V-blocks on the lugs can only be adjusted in a limited range of angles and positions through the connecting grooves. When faced with steering knuckle models with different fork lug spacing and rod lengths, it is often difficult to achieve precise adaptation.

[0005] In view of this, we propose a tooling for machining the center hole of the steering knuckle. Utility Model Content

[0017] The present application will be further described in detail below with reference to the accompanying drawings.

[0018] Reference Figure 1 and Figure 2 This application discloses a tooling for machining the center hole of a steering knuckle, including a base 1. A horizontal plate 11 is fixedly disposed on the outer side of the base 1. A V-shaped block A2 is slidably disposed on the top of the horizontal plate 11. Two positioning posts 3 are symmetrically disposed on the top of the horizontal plate 11. The positioning posts 3 are located on one side of the V-shaped block A2. Several V-shaped blocks B4 are slidably disposed on the top of the horizontal plate 11 away from the V-shaped block A2. Several vertical plates B17 are disposed on both the side of the horizontal plate 11 located on the V-shaped block A2 and the side of the V-shaped block B4.

[0019] The fixture is fixed on the machine tool by the base 1. According to the specifications of the steering knuckle to be processed, the positions of V-block A2, positioning pin 3 and V-block B4 are adjusted respectively so that the rod part of the steering knuckle fits against V-block A2, and the fork lug part is supported and positioned by positioning pin 3 and V-block B4. After ensuring stable positioning, the machine tool can be started to process the center hole. This achieves the effect of flexibly adjusting the positioning structure to be compatible with the processing of multiple steering knuckle models.

[0020] Reference Figure 1 , Figure 2 and Figure 3The top of the horizontal plate 11 has a T-slot A12. A positioning plate A21 is fixedly installed at the bottom of the V-block A2. A T-block A22 is fixedly installed at the bottom of the positioning plate A21. The T-block A22 slides with the T-slot A12. Connecting plates A23 are fixedly installed on both sides of the positioning plate A21. Vertical plates A13 are fixedly installed on both sides of the connecting plate A23 at the top of the horizontal plate 11. A threaded moving ring A24 is fixedly installed on the inner side of one of the connecting plates A23. A screw A25 is provided on the inner thread. One end of the screw A25 is rotatably mounted on the inner side of the corresponding vertical plate A13. A bearing A26 is provided on the outer side of the screw A25. The inner ring of the bearing A26 is fixedly mounted to the screw A25, and the outer ring of the bearing A26 is fixedly mounted on the inner side of the corresponding vertical plate A13. A knob A251 is fixedly mounted on the other end of the screw A25. A limit post A14 is fixedly mounted between the two vertical plates A13 on the other side. The corresponding connecting plate A23 is slidably mounted on the outer side of the limit post A14.

[0021] By rotating the knob A251, the screw A25 is driven to rotate. Since the screw A25 is threadedly engaged with the threaded moving ring A24 and the threaded moving ring A24 is fixed on the connecting plate A23, the rotation of the screw A25 is converted into the linear motion of the connecting plate A23. The connecting plate A23 drives the positioning plate A21 and the V-block A2 to move synchronously. T-block A22 slides along T-slot A12, providing guidance for the movement of V-block A2 and preventing deviation. Limiting post A14 forms a limiting guide for connecting plate A23 on the other side, further improving movement stability. Bearing A26 reduces friction between screw A25 and vertical plate A13, ensuring smooth rotation. By observing the scale line 18 on horizontal plate 11, the movement distance of V-block A2 can be precisely controlled, adapting to steering knuckles with different rod lengths.

[0022] Reference Figure 1 and Figure 2 The base 1 has a mounting hole 15 on its top. The positioning pin 3 is set on the top of the mounting hole 15 through the fixing plate 31. The two positioning pins 3 are driven by external force to move closer or further apart. The two sides of the top of the fixing plate 31 are fixedly provided with connecting plates B32. A bidirectional screw 33 is rotatably provided on the inner side of one of the connecting plates B32. One end of the bidirectional screw 33 passes through the other connecting plate B32 and is fixedly provided with a knob B331. Both sides of the bidirectional screw 33 are threaded with threaded moving rings B34. A moving plate 35 is fixedly provided on the outer side of the threaded moving rings B34. The top of the moving plate 35 is fixedly provided with the positioning pin 3. A limit pin B36 is fixedly provided between the two connecting plates B32. The moving plate 35 is slidably provided on the outer side of the limit pin B36.

[0023] By rotating the knob B331, the bidirectional lead screw 33 is rotated. The threads on both sides of the bidirectional lead screw 33 rotate in opposite directions, causing the two threaded moving rings B34 to move closer or further away from each other along the bidirectional lead screw 33. The threaded moving rings B34 drive the moving plate 35 and the top positioning pin 3 to move synchronously, thereby adjusting the distance between the two positioning pins 3. The movable plate 35 slides along the limiting post B36, providing guidance for the movement of the positioning post 3, ensuring that the two positioning posts 3 always move in parallel, ensuring accurate support and positioning of the steering knuckle fork lugs, and adapting to steering knuckle models with different fork lug widths.

[0024] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The top of the base 1 has a T-slot B16. The bottom of the V-block B4 is fixedly equipped with a positioning plate B41. The bottom of the positioning plate B41 is fixedly equipped with a T-block B42. The T-block B42 and the T-slot B16 are slidably arranged. The inner side of the positioning plate B41 is equipped with a bearing B43. The outer ring of the bearing B43 is fixedly arranged with the inner side of the positioning plate B41. The inner ring of the bearing B43 is fixedly equipped with a threaded moving ring C44. The inner side of the threaded moving ring C44 is threaded with a screw B45. The outer side of the threaded moving ring C44 is fixedly equipped with a connecting ring 46. The outer side of the connecting ring 46 is fixedly equipped with a knob C47. The top of the base 1 is fixedly equipped with upright plates B17 on both sides of the screw B45. The screw B45 is fixedly arranged with the upright plates B17.

[0025] Rotating knob C47 causes the connecting ring 46 and the threaded moving ring C44 to rotate synchronously. Since the screw B45 is fixed between the vertical plates B17 and threadedly engaged with the threaded moving ring C44, the rotation of the threaded moving ring C44 is converted into the linear motion of the positioning plate B41. The positioning plate B41 drives the V-block B4 to slide along the T-slot B16. The T-block B42 engages with the T-slot B16 to provide guidance. The bearing B43 reduces the friction between the threaded moving ring C44 and the positioning plate B41, making rotation adjustment easier. By adjusting the position of multiple V-blocks B4, it can adapt to the fork lug structure with different spacing of the steering knuckle, ensuring stable support.

[0026] In summary, when using the steering knuckle center hole machining fixture disclosed in this application embodiment, the fixture is first securely installed on the machining machine tool through the mounting hole 15 on the base 1 to complete the equipment fixation; Next, according to the specific specifications of the steering knuckle to be processed, activate each adjustment mechanism: rotate knob A251 to adjust the front and rear position of V-block A2 so that it matches the length of the steering knuckle rod; the cooperation between T-block A22 and T-slot A12 and the guiding effect of limit post A14 ensure that V-block A2 moves accurately; rotate knob B331 to adjust the distance between the two positioning posts 3 so that they fit the inner width of the steering knuckle fork lug; rotate knob C47 corresponding to each V-block B4 to adjust the position of V-block B4 so that it matches the outer contour of the steering knuckle fork lug; During the adjustment process, the movement distance of each component can be visually read through the scale line 18 on the horizontal plate 11, improving adjustment efficiency and accuracy. After each positioning structure is adjusted to the correct position, the steering knuckle is placed on the tooling, so that the rod fits into the V-groove of the V-block A2. The inner side of the fork ear is supported by the positioning pin 3, and the outer side is limited by the V-block B4, achieving multi-point positioning. Then, the hydraulic clamping device of the machine tool is activated to clamp and fix the steering knuckle, preventing displacement during processing. During processing, the tooling achieves precise adaptation to steering knuckles of different specifications through multiple sets of adjustable positioning structures, effectively avoiding the positioning deviation problem caused by the limited adjustment range of traditional tooling, ensuring accurate machining position of the center hole. For steering knuckles of the same batch and model, only the above adjustment needs to be completed and each knob locked for the first time. Subsequent processing can be carried out directly, greatly shortening the production preparation time and achieving the effect of compatible processing of multiple models and improving processing efficiency.
