[0022] A hydraulic clamp for clamping a car steering knuckle 1, wherein the steering knuckle 1 has a through hole 11 in the middle, such as... Figures 1 to 4As shown, it includes: a base plate 2, on which bolts are provided for fixing to a machine tool; a first clamp 3, which is disposed on the base plate 2, and includes a first positioning mechanism 31 and a first clamping mechanism 32. The first positioning mechanism 31 is used to position the steering knuckle 1, and the first clamping mechanism 32 is used to clamp the steering knuckle 1 after positioning; the first clamping mechanism 32 includes multiple edge clamping devices 321 and a central clamping device 322. The edge clamping devices 321 include an edge clamping device body 3211 and a first jaw 3212 disposed on the top of the edge clamping device body 3211. The first jaw 3212 can rotate counterclockwise and downward. The pressure is applied to fix the steering knuckle 1; the central clamping device 322 includes a columnar central clamping device body 3221 and a plurality of second clamping claws 3222 disposed on the side wall of the central clamping device body 3221 and centrally symmetrically distributed. The second clamping claws 3222 are rotatably fixed on the clamping device body and can rotate downward to fix the through hole 11 of the automotive steering knuckle 1; the second clamp 4 is disposed on the base plate 2 and includes a second positioning mechanism that is mirror-symmetrical in shape and distribution to the first positioning mechanism 31 and a second clamping mechanism that is mirror-symmetrical in shape and distribution to the first clamping mechanism 32.

[0023] Specifically, the second clamping mechanism also includes multiple second edge clamping devices 321 and a second central clamping device 322. The second edge clamping device 321 includes a second edge clamping device body 3211 and a third gripper disposed on the top of the second edge clamping device body 3211. Unlike the first clamping mechanism 32, the rotation direction of the third gripper is opposite to that of the first gripper 3212, rotating clockwise and pressing down, thereby fixing the steering knuckle 1. The second central clamping device 322 includes a columnar second central clamping device body 3221 and multiple fourth grippers disposed on the side wall of the second central clamping device body 3221 and symmetrically distributed centrally. The fourth grippers are rotatably fixed to the second clamping device body and can rotate downward, thereby fixing the through hole 11 of the vehicle steering knuckle 1. Specifically, the first clamp 3 can position and install one of the automotive steering knuckles 1, and the second clamp 4 can simultaneously position and install another automotive steering knuckle 1, that is, it can position and install two steering knuckles 1 at the same time. The first clamp 3 and the second clamp 4 are synchronously controlled by machine tool signals. After positioning by the first positioning mechanism 31 and the second positioning mechanism, the first clamping mechanism 32 and the second clamping mechanism receive a given signal from the machine tool. The two first jaws 3212 rotate counterclockwise by 90° and press down, and the two third jaws rotate clockwise by 90° and press down. The three second jaws 3222 and the central clamping device body 3221 are rotatably connected, and the three fourth jaws and the second central clamping device body 3221 are rotatably connected. After receiving a signal, the third jaws and fourth jaws rotate synchronously, tilt downward and lock, thereby completing the fixing of the central through hole 11 of the automotive steering knuckle 1.

[0024] As an optional implementation, the first positioning mechanism 31 includes a plurality of positioning surfaces 311, the number of which matches the number of the second grippers 3222. The positioning surfaces 311 are disposed at the bottom of the second grippers 3222 and are used to cooperate with the second grippers 3222 to perform surface positioning of the steering knuckle 1.

[0025] Specifically, the positioning surface 311 is semi-circular, with a raised first positioning point 3111 at the top. The positioning surface 311 being located at the bottom of the second gripper 3222 means that the first positioning point 3111 and the second gripper 3222 are coaxial in the vertical direction. In use, the steering knuckle 1 is first positioned using the positioning block 313 and the anti-deviation device 315 to prevent the workpiece from being misaligned. Then, surface positioning is performed using the positioning surface 311 and the surface positioning pin 312 to place the workpiece at a suitable height. Finally, angular positioning is performed using the corner positioning pin 314. After complete positioning, the first clamping mechanism 32 clamps the steering knuckle 1.

[0026] As an optional implementation, the first positioning mechanism 31 further includes a plurality of surface positioning pins 312, the number of which matches the number of the first grippers 3212. The surface positioning pins 312 are disposed at the bottom of the first grippers 3212 and are used to cooperate with the first grippers 3212 to perform surface positioning on the steering knuckle 1.

[0027] Specifically, the top of the face positioning pin 312 is provided with a raised second positioning point. The fact that the face positioning pin 312 is located at the bottom of the first gripper 3212 means that the second positioning point and the first gripper 3212 are coaxial in the vertical direction.

[0028] As an optional implementation, the first positioning mechanism 31 further includes a plurality of positioning blocks 313, each positioning block 313 including an arc-shaped surface 3131, the arc-shaped surface 3131 matching the shape of the steering knuckle 1.

[0029] Specifically, the arc-shaped surface 3131 of the positioning block 313 is located on the side near the central clamping device 322. The second clamp 4 is provided with a plurality of second positioning blocks 313 symmetrically distributed with the positioning block 313. In a preferred embodiment, one of the positioning blocks 313 is located on the axis of symmetry between the first clamp and the second clamp 4. The positioning block 313 and its corresponding second positioning block 313 can be two separate, independent positioning blocks 313, or they can be a single, integrated positioning block 313.

[0030] As an optional implementation, the first positioning mechanism 31 further includes a plurality of corner positioning pins 314, which are close to the arc-shaped surface 3131 and can cooperate with the positioning block 313 to perform angular positioning of the steering knuckle 1.

[0031] Specifically, the corner positioning pin 314 has a raised third positioning point on its top. The corner positioning pin 314 is circular and close to the arc-shaped surface 3131, and the two are tangent to each other.

[0032] As an optional implementation, the first positioning mechanism 31 further includes an anti-deviation device 315, which is used to prevent the steering knuckle 1 from deviating.

[0033] As an optional implementation, there are two edge clamping devices 321.

[0034] Specifically, there are two edge clamping devices 321, with the line connecting the central clamping mechanism and the second central clamping mechanism serving as a dividing line, and the devices located at different ends above and below the dividing line. The edge clamping mechanisms at both ends can clamp the steering knuckle 1 evenly.

[0035] As an optional implementation, there are three second grippers 3222.

[0036] Specifically, there are at least three grippers, which can stably fix the central through hole 11 of the steering knuckle 1.

[0037] By adopting the above technical solution, a hydraulic clamp for automotive steering knuckle 1 is provided, which is equipped with two clamps, each including a positioning mechanism and a clamping mechanism, capable of simultaneously positioning and clamping two different steering knuckles 1. The clamping mechanism includes multiple edge clamping mechanisms and a central clamping mechanism, capable of simultaneously clamping the through hole 11 in the center of the steering knuckle 1 and the side edges. First, the steering knuckle 1 is positioned surface-wise and angularly by the positioning mechanism, and then clamped by the clamping device, thereby fixing the steering knuckle 1 on the clamp, completing one loading operation. The positioning is accurate and the operation is simple.
