Description

technical field [0001] The invention relates to a milling processing device for mechanical parts, in particular to a milling processing device for an assembly surface of an automobile rear torsion beam wheel hub connection bracket, belonging to the technical field of milling of special workpieces. Background technique [0002] Toe angle and camber are two important parameters for car wheel alignment. The toe angle means that when looking down at the wheel, the wheel does not point in a straight line to the forward direction, but has some inward or outward angles. The camber angle means that when the wheel is viewed from front to back, the wheel is not perpendicular to the ground, but has some inward or outward angles. [0003] The rear torsion beam of the automobile is a key component of the rear suspension assembly of the vehicle. It is connected with the body and rear wheels to carry the rear load of the automobile. as attached figure 1 The shown rear torsion beam 1 for ...
