Fixed mount is multidiameter structure, and by front spindle nose, window housing location-plate, steel pipe, backboard, rear axle head group becomes, and front spindle nose, steel pipe, backboard, rear spindle nose weld together successively, and window position plate is welded on steel pipe.
Front spindle nose is the axle with flange disk, and the axle of flange face front end is processed with screw thread, screw thread and nut and pad with the use of, flange disk in the past frame posterior medial support before frame, nut and pad and threaded engagement in the past frame front outsides compress front frame;
Window housing location-plate is rectangular configuration, is welded on steel pipe, and its center is processed with groove, has screwed hole in groove, the tapped through hole in the boss on the screwed hole in groove and window housing cover plate with the use of; During welding, window housing cover plate is placed in window housing, by screwed hole preset in two tapped through holes preset on window housing cover plate and bolt and window position plate upper groove, window housing cover plate is fixed on window housing location-plate, plays the effect supporting stationary window housing cover plate;
Backboard is the disk of band boss, preset lightening core and four screwed holes on backboard, and the boss diameter of backboard is slightly less than the internal diameter of after-frame, and at inner support after-frame, backboard disk diameter is greater than after-frame external diameter, is convenient to after-frame bottom surface and falls within disk; Rear spindle nose is cylindrical structure, is used for titanium alloy cover body laser weld Deformation control frock to be fixed on jig;
Outer sleeve is hollow disc structure, its disc face is processed with four through holes, and through hole is corresponding with four screwed hole positions on backboard; Outer sleeve internal diameter is greater than after-frame external diameter and is less than backboard disk external diameter, during use, after outer sleeve being enclosed within after-frame boss, is fixed on backboard by after-frame by four bolts.
First be fixed on jig by fixed mount by rear spindle nose during use, then successively by the after-frame of titanium alloy cover body, conically shaped, front frame is arranged on fixed mount.After-frame is fixed by bolt and pad with outer sleeve afterwards; With nut and pad, front frame is compressed, finally window housing is arranged on conically shaped opening, and be fastened on window position plate with by window housing cover plate.Can weld after installation.
The welding of the titanium alloy cover body that this frock is carried out, effectively can control longitudinal contraction and the torsional deflection of cylindrical shell, ensures the axiality requirement of titanium alloy cover body.
