Description

Technical Field

[0001] The utility model relates to a machining device, in particular to a machining device for an automobile steering knuckle, and belongs to the technical field of automobile steering knuckle machining equipment. Background Art

[0002] With the rapid development of the automobile industry, the requirements for the precision and quality of automobile parts are getting higher and higher. As one of the main parts on the steering axle of an automobile, the steering knuckle can make the car run stably and sensitively transmit the driving direction. The function of the steering knuckle is to bear the front load of the car, support and drive the front wheel to rotate around the kingpin to make the car turn.

[0003] In the prior art, when milling the normal holes and end faces of the steering knuckle, the processing is generally carried out in a divided process and multiple clamping manner. This processing method is not only inefficient, but also it is difficult to ensure the position accuracy of each processing part due to different clamping processes. In addition, the traditional processing method can generally only clamp one steering knuckle at a time. When clamping the face of the same steering knuckle or changing to another steering knuckle for processing, it is necessary to stop the machine for clamping, which seriously affects the processing efficiency and accuracy. In addition, due to the long knuckle arm of the steering knuckle, overcutting is very likely to occur during the cutting process due to vibration caused by excessive suspended area.
