Description
Technical field
The utility model relates to a kind of confined space bush press-fit device, belongs to a kind of fitting device.
Background technology
Aircraft complex connector lining many places are positioned at confined space, and the pressing of lining is installed very difficult, and directly pressing bushing device lacks directional guide, due to application of force insufficient space, lining discontinuity, easily deforms, breakage, and precision falls flat.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of confined space bush press-fit device, and this device is realized the conversion in application of force space, makes lining in the directed pressing of confined space, and improves efficiency and the precision of bush press-fit.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of confined space bush press-fit device, in the through hole of cushion block, be provided with limiting stand, limiting stand is provided with the self-aligning thrust roller bearing of coaxial setting, the outer end of self-aligning thrust roller bearing is provided with nut, the inner hole thread connecting mandrel of nut, and the inner end of mandrel stretches out cushion block, and be flexibly connected limited block, on limited block, be flexibly connected clamp.
Described mandrel end is provided with cushion block convex shoulder.
The structure that this confined space bush press-fit device adopts threaded mandrel to be connected with nut, can be by the rectilinear motion that rotarily drives mandrel of nut, and drives lining to moving to inner bore of part by clamp, thereby realizes the object of gland; This device adopts the structure of self-aligning thrust roller bearing, the force of sliding friction producing can be converted to force of rolling friction in screw thread rotation process.
Be provided with cushion block convex shoulder in mandrel end, prevent that lining rotation effective protection from press-fiting lining part and not being scratched.
Brief description of the drawings
Fig. 1 is the structural representation of slip-off preventing elastic locating mechanism.
Detailed description of the invention
As shown in Figure 1, a kind of confined space bush press-fit device, in the through hole of cushion block 4, be provided with limiting stand, limiting stand is provided with the self-aligning thrust roller bearing 3 of coaxial setting, to bear axial force and radial load, the outer end of self-aligning thrust roller bearing 3 is provided with nut 2, the inner hole thread connecting mandrel 1 of nut 2, and rotating nut 2 can be realized the rectilinear motion of mandrel 1; The inner end of mandrel 1 stretches out cushion block 4, and is flexibly connected limited block 8, is flexibly connected clamp 7 on limited block 8, the movement of the interior restriction lining 6 of clamp 7, and promote lining 6 to pressing in the endoporus of part 5.
Described mandrel 1 end is provided with cushion block convex shoulder 9, and the diameter of this cushion block convex shoulder 9 equates with the internal diameter of part 5, and one end of lining 6 and cushion block convex shoulder 9 end faces are to it, the planes overlapping of the other end and clamp 7.
When this confined space bush press-fit device work, cushion block 4, self-aligning thrust roller bearing 3, nut 2 and mandrel 1 are assembled, then the inner of mandrel is inserted into treating in pressing sleeve hole of part 5; Limited block 8 and clamp 7 are coordinated, then lining 6 is inserted on limited block 8, then limited block 8 and cushion block convex shoulder 9 are threaded.Rotating nut 2, band moving mandrel moves backward, and clamp 7 drives lining 6 to move in hole in piece part, thereby realizes the bush press-fit in confined space.
Claims (2)
1. a confined space bush press-fit device, it is characterized in that: in the through hole of cushion block (4), be provided with limiting stand, limiting stand is provided with the self-aligning thrust roller bearing (3) of coaxial setting, the outer end of self-aligning thrust roller bearing (3) is provided with nut (2), the inner hole thread connecting mandrel (1) of nut (2), the inner end of mandrel (1) stretches out cushion block (4), and is flexibly connected limited block (8), the upper clamp (7) that is flexibly connected of limited block (8).
