Due to processing costs and trial production cycles, it is impossible to purchase mass production rapid positioning tooling. In the past, the trial production of steering knuckles used self-made fixtures, and alignment was required piece by piece during the processing process, resulting in problems such as long trial production cycles and unstable processing accuracy.

[0003] The utility model patent application document with publication number "CN209319294U" discloses a clamping and positioning tool for a steering knuckle, which belongs to the technical field of CNC machining tooling for automobile parts, and includes a base plate, a spiral arc centering block, a first cylindrical support block, a second cylindrical support block, a third cylindrical support block and a clamping mechanism; the height difference of the first cylindrical support block, the second cylindrical support block and the third cylindrical support block is the same as the height difference of the three corresponding process bosses on the steering knuckle, and the clamping mechanism includes a pad bolt, a stud and a pressure plate, the stud is screwed into the base plate, the pad bolt is located at the bottom of the stud and above the base plate, the pressure plate is located on the upper part of the stud, and the position of the pressure plate on the stud can be adjusted up and down; this technical solution solves the problem that the automobile steering knuckle cannot be quickly positioned and clamped during the trial production process. By using the tooling of the utility model, the steering knuckle can be quickly positioned, the processing efficiency is improved, and the operation is simple, the precision is high, and the cost is extremely low.

[0004] The clamping and positioning tooling for the steering knuckle disclosed in the above document has the following defects: after the steering knuckle is fixed, the technical solution cannot adjust the angle of the steering knuckle to a direction that is convenient for work, and has low flexibility, thereby reducing work efficiency.

[0005] It can be seen from this that the existing clamping and positioning tooling for the steering knuckle does not have a good rotatable structure, and it is necessary to improve the existing deficiencies and provide a clamping tooling for the pin hole of the steering knuckle.
