Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts, and in particular relates to a high-efficiency clamping and positioning device for an automobile steering knuckle and a use method thereof. Background Art

[0002] The steering knuckle, also known as the "ram's horn", is one of the important parts in the steering axle of the car. It can make the car run stably and transmit the driving direction sensitively. The function of the steering knuckle is to transmit and bear the load in front of the car, support and drive the front wheel to rotate around the kingpin to turn the car. When the car is in motion, it is subjected to variable impact loads, so it is required to have high strength. The steering knuckle is also the hinge for wheel steering, generally in the shape of a fork. The upper and lower forks have two coaxial holes for installing the kingpin, and the steering knuckle journal is used to install the wheel. The two ears of the pin hole on the steering knuckle are connected to the fist-shaped parts at both ends of the front axle through the kingpin, so that the front wheel can deflect a certain angle around the kingpin to turn the car.

The above scheme positions and clamps the car steering knuckle through the first positioning part, the second positioning part and the third positioning part; however, the clamping efficiency of this scheme is low, and after the positioning and clamping is completed, the processing content of the car steering knuckle is less.

[0004] Therefore, the present invention provides an efficient clamping and positioning device for an automobile steering knuckle and a method for using the same, which are used to solve the technical problems existing in the above-mentioned background technology. Summary of the invention
