[0002] Patent authorization publication number CN113211144B discloses a jig for drilling kingpin holes in steering knuckles with arms. The jig comprises a base and a positioning device mounted on the base, a positioning body, and a clamping device. The positioning body is provided with a positioning surface for positioning the steering knuckle disc, and the positioning surface is provided with a positioning hole for positioning the steering knuckle journal. The angle between the positioning surface and a horizontal plane is equal to the angle between the steering knuckle disc and the axis of the steering knuckle kingpin hole. One side of the positioning body is also provided with a steering knuckle arm positioning portion for positioning the steering knuckle arm. During positioning, the steering knuckle journal is inserted into the positioning hole until the steering knuckle disc contacts the positioning surface. The steering knuckle arm is then positioned using the steering knuckle arm positioning portion. Finally, the steering knuckle is secured to the positioning body by the clamping device. This jig has the advantages of good stability, high positioning accuracy, simple clamping process, high production efficiency, and high drilling accuracy. However, in the prior art, when the device clamps the steering knuckle kingpin, the kingpin may vibrate slightly during drilling, causing the clamping of the knuckle kingpin to loosen.

[0006] In addition, a preferred structure is that a sliding groove is provided inside the support, and the sliding groove is slidably connected to the slide rod. By providing the sliding groove, the movement of the slide rod is guided.

[0007] In addition, a preferred structure is that a slider is fixedly connected to the lower end of the clamping block, and the slider is slidably connected to the support. By providing the slider, auxiliary support is provided for the clamping block.

[0008] In addition, a preferred structure is that one end of the spring is fixedly connected to the support, and the other end of the spring is fixedly connected to the friction ring. By providing the spring, the friction ring is easy to reset.

[0009] In addition, a preferred structure is that a bevel block is welded to the end of the cylinder rod of the cylinder, and the bevel block is in contact with the friction ring. By providing the bevel block, the friction ring is pressed down.

[0010] The beneficial effects of the utility model are:

[0011] The motor drives the turntable to rotate, so that the guide groove and the sliding pin cooperate, so that the sliding rod drives the clamping block to move, so that the clamping block can be adjusted to clamp the steering knuckle kingpins of different sizes, and the cylinder drives the inclined block to move, so that the friction ring can be pressed against the turntable, so that the turntable is limited, and the steering knuckle kingpin is clamped stably.
