Abstract
The utility model relates to a kind of many auricles crossing point holes pressure and pulls out bush tool, male connection is provided with in one end of guide post, male connection is connected with and pulls out sleeve, the one end of pulling out sleeve is provided with the internal thread hole corresponding with male connection, internal thread hole is threaded with male connection, gland axle is provided with, wherein guide post and external diameter and the bushing inner diameter consistent size of pulling out sleeve, the external diameter of gland axle and Outer Diameter of lining consistent size at the other end pulling out sleeve; On the outer face of gland axle, contact has extension rod.This frock well can ensure that the clearance requirement between the axiality of the rear crossing point holes of docking and fork ear, ensure that the moving-mass of parts.
Description
Technical field
The utility model relates to a kind of many auricles crossing point holes pressure and pulls out bush tool, belongs to frock field.
Background technology
After Large Aircraft Components docking, lower aerofoil has 14 groups of intersection points, and intersection point total length is 2100mm, often organizes intersection point and coordinates for pitching ear, and for ensureing the motion state of parts, the clearance requirement between docking back vent ear is not less than 0.3mm.Because intersection point part is weldment, after part machinery processing, welding and heat treatment, the position of 14 auricles has deviation relative to theoretical value, two parts are become at intersection point Assembly of the parts, after pressing the docking of benchmark auricle again, gap between 14 groups of fork ears is often less than 0.3mm, even interfere, need by designing requirement, convex shoulder lining to be replaced with flange lining, to ensure movement clearance for this reason.Because now intersection point part has been assembled into two parts, distance between two auricles is only 84mm, processing space is very narrow and small, it is the axiality requirement of crossing point holes after guarantee fine finishining simultaneously, intersection point axiality more after resleeve is not more than 0.4mm, therefore adopt traditional pressure to pull out bush tool method, cannot meet design requirement.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of many auricles crossing point holes pressure and pulls out bush tool, and this frock well can ensure that the clearance requirement between the axiality of the rear crossing point holes of docking and fork ear, ensure that the moving-mass of parts.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of many auricles crossing point holes pressure pulls out bush tool, male connection is provided with in one end of guide post, male connection is connected with and pulls out sleeve, the one end of pulling out sleeve is provided with the internal thread hole corresponding with male connection, internal thread hole is threaded with male connection, gland axle is provided with at the other end pulling out sleeve, wherein guide post and external diameter and the bushing inner diameter consistent size of pulling out sleeve, the external diameter of gland axle and Outer Diameter of lining consistent size; On the outer face of gland axle, contact has extension rod.
Described extension rod can form by many.
Described guide post and pulling out between sleeve is connected by taper thread.
This many auricles crossing point holes pressure is pulled out bush tool and is adopted split type guide post, pulls out sleeve and extension rod structure, can carry out plug process targetedly, make the process of lining more quick and precisely, thus increase work efficiency pending lining.
Accompanying drawing explanation
Fig. 1 is the explosive view that many auricles crossing point holes pressure pulls out bush tool.
Fig. 2 be many auricles crossing point holes pressure pull out bush tool pull out lining duty.
Fig. 3 is the pressure lining duty that many auricles crossing point holes pressure pulls out bush tool.
Detailed description of the invention
As shown in Figure 1, a kind of many auricles crossing point holes pressure pulls out bush tool, male connection 2 is provided with in one end of guide post 1, male connection 2 is connected with and pulls out sleeve 3, the one end of pulling out sleeve 3 is provided with the internal thread hole 4 corresponding with male connection 2, and internal thread hole 4 is threaded with male connection 2, is provided with gland axle 5 at the other end pulling out sleeve 3, wherein guide post 1 and external diameter and the bushing inner diameter consistent size of pulling out sleeve 3, the external diameter of gland axle 5 and Outer Diameter of lining consistent size; On the outer face of gland axle 5, contact has extension rod 6.
Described extension rod 6 can form by many, to ensure to exert a force in outside myopia.
Described guide post 1 and pulling out between sleeve 3 is connected by taper thread, thus ensures the axiality that coordinates.
Its course of work is: when parts docking occurs that auricle is interfered or gap hour, the intersection point lining at the little place of component interference or gap need be changed, need to extract the method for lining as shown in Figure 2: the position residing for auricle choose suitable dimension guide post 1, pull out sleeve 3 and extension rod 6, from auricle to be processed last notch, guide post is installed, after auricle to be processed, a notch is installed and is pulled out sleeve 3, then guide post 1 with pull out sleeve 3 and be threaded connection, now gland axle 5 inner face is fitted on the end face of lining; The outside of extension rod 6 is applied impulsive force, and namely gland axle 5 promotes gland and auricle departs from.
After lining is removed, the method press-fited is as shown in Figure 3: first install guide post 1 from the last notch of auricle to be processed, gland axle 3 overlaps the lining after changing, and from auricle notch to be processed, gland axle 3 is installed, guide post 1 is threaded with gland axle 5, and now guide post 1 should be arranged in last group of crossing point holes of auricle to be processed, pull out sleeve 3 be positioned at treat pressure lining on rear side of, in side of never regarding sb. as an outsider to extension rod 6 one impulsive forces, by gland axle 5 by auricle corresponding for lining press-in.
