A fully automatic clamping and alignment tool for axle housing and a method of using the same

Abstract

The present invention provides a fully automatic clamping and alignment tool for a bridge housing and a method for using the same. The method includes: A. Synchronous jaw clamping: using the reciprocating motion of the clamping oil cylinder to drive the slider, gear and rack to realize the synchronous clamping and loosening of the jaws formed by the clamp arm A and the clamp arm B; B. Synchronous elastic support: using four slide columns and the springs and cores therein to make the four positioning support points rise and fall synchronously; C. Clamping of the automatic alignment device: using a lifting oil cylinder to realize two actions: the lifting oil cylinder connects the wedge block to move up and down, and limits the up and down travel of the auxiliary plate through two inclined grooves on the bracket. When the auxiliary plate rises to the working height and no longer rises, the lifting oil cylinder drives the wedge block to continue to rise. At this time, the two support blocks are opened simultaneously along the positive and negative directions of X to realize the alignment of the bridge housing center and the tool center, and tighten the inner hole; D. After the synchronous jaws and automatic alignment actions are completed, the four tightening oil cylinders are started and tighten the outer surface of the middle part of the bridge housing. The present invention has a simple structure, is easy to use, is fast to clamp, and can automatically align after clamping, has no error, and is conducive to cooperating with drilling and milling processes.
