The invention provides a special front shaft
machining clamp capable of automatically aligning a
caster angle and an inward camber. The
caster angle and the inward camber of a workblank are automatically aligned within a certain amount of deformation of the workblank of a front shaft, a front shaft
leaf spring face is directly milled after alignment is performed, and a coordinated
system using the aligned front shaft
leaf spring face as the positioning basis is built and used as the basis during subsequent
machining. According to the scheme, the clamp comprises a front shaft H-
shaped beam portion auxiliary supporting structure, an H-
shaped beam portion auxiliary clamping structure, a clamping H-
shaped beam portion, a wedge iron self-locking clamping unit, a manual thread clamping unit, a floating supporting device and an inward camber correcting unit, wherein the front shaft H-shaped beam portion auxiliary supporting structure can abut against the front shaft H-shaped beam portion so as to play a supporting role, the H-shaped beam portion auxiliary clamping structure can compress the portion above the front shaft H-shaped beam portion, the clamping H-shaped beam portion is matched with the H-shaped beam portion auxiliary supporting structure, the wedge iron self-locking clamping unit is arranged at the rear portion of the front shaft
leaf spring face, the manual thread clamping unit is arranged at the front portion of the front shaft leaf spring face and used in cooperation with the wedge iron self-locking clamping unit to clamp the front shaft leaf spring face portion, the floating supporting device is arranged at the lower portion of the front shaft leaf spring face, and the inward camber correcting unit is arranged at the position of a front shaft left
fist face and used for correcting the front shaft inward camber.
