Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a special fixture for processing automobile suspension holes comprises a shaft connecting spacer 1, a base 2, a suspension 3, an adjustable clamping plate 4, a cylinder shaft 5, a mandril 6, a right connecting block 7, a right clamping plate 8, a right cylinder 9, a main cylinder 10, a left cylinder 11, a suspension outer edge 12, a left clamping plate 13, a vertical reinforcing plate 14, a vertical plate 15, a left connecting block 16 and a main cylinder spacer 17.

This device adopts the modularization manufacturing, the left and right sides becomes the symmetry, used spare part is all the same, base 2 comprises two the same bottom plates, be equipped with riser 15 respectively about on the bottom plate, there is upright reinforcing plate 14 on riser 15's central line, guarantee the use strength of reinforcing plate, it is equipped with the mounting hole respectively to lean on the edge on the riser about, the hole on the riser is pressed from both sides through right cylinder 9 and left cylinder 11's cylinder axle 5, axle connecting spacer 1 passes through the bolt with right cylinder 9 and left cylinder 11 and presss from both sides tight riser fixed position, cylinder axle 5 is connected with left splint 13 and right splint 8 respectively and is used for fixed suspension outward flange 12.
