The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheel to rotate around the kingpin to steer the car. The shape of the steering knuckle is relatively complex, and it concentrates the structural characteristics of four types of parts such as shaft, sleeve, disc ring, and fork frame. It is mainly composed of three parts: supporting journal, flange, and fork frame. The structural shape of the supporting journal is a stepped shaft. Its structural characteristics are a rotating body composed of coaxial outer cylindrical surface, conical surface, threaded surface, and shoulder, transition fillet and end face perpendicular to the axis; the flange includes flange surface, evenly distributed connecting bolt through holes and threaded holes for steering limit; the fork frame is composed of the upper and lower ears and flange surface of the steering knuckle to form the fork frame shape.

[0054] A hydraulic power source 5 , wherein the hydraulic power source 5 is connected to the adjusting component 3 , and the hydraulic power source 5 is used to drive the adjusting component 3 to operate.

[0055] In the present technical solution, the transmission assembly 4 is used to adjust the positions of multiple clamps 2 at the same time when the hydraulic power source 5 moves up and down, so that the multiple clamps 2 can clamp and release the steering knuckle, and the up and down movement of the hydraulic lifting rod 51 is used to provide power for the rotation of the threaded column 31, which is more precise than the traditional motor transmission control, thereby ensuring the clamping accuracy of the steering knuckle. At the same time, multiple clamps 2 can increase the contact area with the steering knuckle, and each clamp 2 can be manually controlled to move, which makes it easier to adapt to irregular-shaped steering knuckles and makes the clamping of the steering knuckle more stable.

[0056] The support frame 1 includes a support platform 11 and a reinforcement base plate 12 . The support platform 11 is disposed above the reinforcement base plate 12 . The support platform 11 and the reinforcement base plate 12 are connected via a plurality of support columns 13 .

[0058] The adjusting assembly 3 includes a threaded column 31, the threaded column 31 is rotatably connected to the inner wall of the support platform 11, and a movable plate 32 is threadedly connected to the surface of the threaded column 31;

[0059] One end of the threaded column 31 is connected to a power gear 33, and a side of the power gear 33 is meshedly connected to a moving rack 34, and the moving rack 34 is slidably connected to the support platform 11, and the lower end of the moving rack 34 is connected to the transmission assembly 4;

[0060] The top of the moving plate 32 is connected to the bottom of the clamping member 2 .

[0061] In the present technical solution, the position of the clamping member 2 can be adjusted by using the adjusting assembly 3 , so that the steering knuckle can be clamped and released by using the adjusting assembly 3 .

[0062] When in use, the hydraulic power source 5 drives the moving rack 34 to move, thereby driving the power gear 33 to rotate, and then driving the corresponding threaded column 31 to rotate. When the threaded column 31 rotates, the transmission assembly 4 can drive other threaded columns 31 to rotate;

[0063] When the threaded column 31 rotates, it can drive the moving plate 32 and the anti-deflection strip 35 to move, thereby driving the clamping member 2 to move in the same direction, so that multiple clamping members 2 can fix the steering knuckle from multiple positions, thereby increasing the stability of the steering knuckle when clamping.

At this time, the secondary rotating shaft 312 will not drive the main threaded shaft 311 to rotate, and the clamping member 2 here will not move, thereby increasing the flexibility of the clamping member 2 when in use.

[0068] Anti-deflection strips 35 are fixedly connected to both sides of the movable plate 32 , and the anti-deflection strips 35 are slidably connected to the inner side wall of the support platform 11 .

[0074] In the present technical solution, the transmission assembly 4 is used to allow the multiple threaded columns 31 to rotate simultaneously, thereby allowing the multiple clamping members 2 to move simultaneously.

[0075] When the power gear 33 drives the threaded column 31 to rotate, it can drive the corresponding side bevel gear 42 to rotate, thereby driving the center bevel gear 41 to rotate. At this time, it can drive other side bevel gears 42 to rotate, thereby driving other threaded columns 31 to rotate, so that multiple clamping parts 2 can move at the same time to complete the clamping or releasing operation of the steering knuckle.

[0076] The hydraulic power source 5 includes a hydraulic lifting rod 51, the hydraulic lifting rod 51 and a follower plate 52, and the hydraulic lifting rod 51 is installed on the bottom surface of the support platform 11;

[0077] The bottom end of the hydraulic lifting rod 51 is connected to a follower plate 52 , and the top of the follower plate 52 is connected to two pairs of movable racks 34 .

[0078] In the present technical solution, the hydraulic power source 5 can provide driving force for the movement of the movable rack 34 .

[0079] When in use, the hydraulic lifting rod 51 is used to drive the follower plate 52 to move up and down, thereby driving the follower plate 52 to move in the same direction, and further driving the moving rack 34 to move in the same direction.

[0080] A track shaft 37 is fixedly connected to the inner side of the fixed frame plate 36 , and the surface of the track shaft 37 is slidably connected to the movable rack 34 .

[0081] In the present technical solution, the track shaft 37 can be used to limit the moving track of the moving rack 34 to prevent the moving rack 34 from shaking greatly when moving.

[0083] In this technical solution, the support portion 14 can be used to support the structure of the reinforced bottom plate 12 .

[0084] The support portion 14 may be a fixed support leg, a movable wheel or other structure that enables the reinforced bottom plate 12 to have a certain distance from the ground.

[0085] The top of the fixed frame plate 36 is connected to the top plate 6 or is not connected to any structure. When the top plate 6 is connected, the fixed frame plates 36 on both sides can be further fixed.
