[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figure 1-5The hydraulic tooling for horizontal machining of steering knuckles according to this utility model includes a base 1, on which a center positioning mechanism 2 is provided. The cavity of the center positioning mechanism 2 matches the shape of the steering knuckle housing. The center positioning mechanism 2 is used for center positioning of the steering knuckle housing. Several air ports 21 are provided around the center positioning mechanism. The air ports 21 are used to blow away the debris generated during the machining of the steering knuckle housing and then remove the housing to avoid metal debris falling into the center positioning mechanism 2, which would cause misalignment. The tooling is also provided with a steering knuckle housing ear fixing mechanism. The fixing mechanism includes a main pressure head 3 and a corresponding support head 31. An angular positioning head 4 is also provided on the base 1 corresponding to the steering knuckle ear. The angular positioning head 4 is used to fix the steering knuckle housing to prevent it from tilting.

[0025] The support head 31 includes a support portion 311 and a drive portion 312. The drive portion 312 moves up and down to drive the support portion 311 to extend and retract left and right. Figure 3 The support part 311 is provided with an oblique groove 3111, and the drive part 312 is provided with an oblique block 3121 that cooperates with the groove 3111. The drive part 312 moves up and down to drive the support part 311 to extend and retract left and right.

[0026] The drive unit 312 is powered by the bottom hydraulic cylinder.

[0027] The base 1 is also provided with an oblique auxiliary support head 5 that matches the shape of the steering knuckle housing.

[0028] The telescopic head of the angular positioning head 4 is set obliquely upward, perpendicular to the contact surface of the steering knuckle housing ear.

[0029] The auxiliary support head 5 and the angular positioning head 4 are driven by hydraulic cylinders.

[0030] Working principle:

[0031] Place the steering knuckle housing into the center positioning mechanism 2, such as the lug of the steering knuckle housing. Figure 1 The main pressure head 3 and the corresponding support head 31 are placed between them. Then, the pressure head 3 extends under the drive of the hydraulic cylinder and firmly clamps the ear of the steering knuckle housing. At the same time, the auxiliary support head 5 extends under the drive of the hydraulic cylinder and abuts against the opposite side of the steering knuckle housing. The angular positioning head 4 extends under the drive of the hydraulic cylinder and abuts against the ear of the steering knuckle housing at an angle, thus completing the clamping and fixing of the steering knuckle housing.
