Abstract
The utility model discloses a kind of aerospace parts disassembling fixture for belonging to maintenance tool scope.The frock is to expand the following of guide housings to be sleeved on outside conical surface expansion piece, and one end of guide spiro rod is flexibly connected with conical surface expansion piece center protrusion cylinder, and guide spiro rod is threadedly coupled with torque nut；The other end of guide spiro rod is fixed after passing through torque nut by attaching nut and guide rod, and centre bore and the guide rod outside diameter of counterweight are slidably matched, and guide rod top is screwed with fixing nut.Turn torque nut, pulling conical surface expansion piece is upward, its conical surface expands outwardly the circular arc pawl of expansion guide housings, will be sleeved on workpiece outside expansion guide housings and expands, smoothly removes workpiece.Meanwhile disassembling fixture imbalance is produced during counterweight Torque-adjusting nut turn, workpiece unbalance stress is avoided, causes workpiece deflection, causes weak part to be damaged, the aviation accessory for ensureing to be disassembled will not secondary injury.This disassembling fixture is simple in structure, easy to operate, and accommodation is extensive.
Description
Technical field portion
The utility model belongs to maintenance tool scope, more particularly to a kind of aerospace parts disassembling fixture.
Background technology
It is conventional to be dismantled using to workpiece heating and screwdriver cooperation when aviation accessory repairs, heating and screwdriver
Compounding practice, is easily damaged parts, and often resulting in workpiece deformation cannot use, and workpiece is dismantled using lever principle,
Unbalance stress is easily caused, caused workpiece deflection, makes the weak part of workpiece deform, and workpiece may be caused secondary broken
It is bad；Therefore, the present inventor designs a kind of aviation accessory disassembling fixture for having the function of to increase torque, overcomes existing heating and spiral shell
The deficiency of silk knife compounding practice.
Utility model content
The purpose of this utility model is a kind of aerospace parts disassembling fixture of deficiency proposition for above-mentioned existing disassembling fixture,
It is characterized in that, the structure of the aviation accessory disassembling fixture is to expand the following of guide housings to be sleeved on outside conical surface expansion piece,
One end of guide spiro rod is flexibly connected with conical surface expansion piece center protrusion cylinder, and guide spiro rod passes through to be set above expansion guide housings
It is threadedly coupled after putting cylindrical center's pilot hole with torque nut；The other end of guide spiro rod pass through torque nut after by connecting spiral shell
Mother fixes with guide rod, and centre bore and the guide rod outside diameter of counterweight are slidably matched, and guide rod top is screwed with fixing nut.
The conical surface internal diameter and conical surface expansion piece outer circumferential surface sliding fit of the expansion guide housings lower part, and it is split into 4-6 circle
Arc pawl, expands and cylindrical center's pilot hole and guide spiro rod outside diameter sliding fit is set above guide housings.
For the torque nut in guide spiro rod turn, pulling conical surface expansion piece is upward, its conical surface makes expansion guide housings
Circular arc pawl expand outwardly, will be sleeved on expansion guide housings outside workpiece expand, smoothly remove workpiece.
The utility model beneficial effect is moved on the guide bar by counterweight, is avoided workpiece unbalance stress, is caused workpiece
Deflection, causes weak part to be damaged, ensure the aviation accessory that is disassembled will not secondary injury, the letter of this disassembling fixture structure
Single, easy to operate, accommodation is extensive.
Brief description of the drawings
Fig. 1 is disassembling fixture structural upright schematic diagram.
Fig. 2 is the profile of Fig. 1.
Embodiment
The utility model proposes a kind of aerospace parts disassembling fixture, it is explained below in conjunction with the accompanying drawings.
Fig. 1, Fig. 2 show disassembling fixture structure diagram.The structure of aviation accessory disassembling fixture shown in figure is expansion
The following of guide housings 6 is sleeved on the outside of conical surface expansion piece 7,8 one end of guide spiro rod and the protrusion cylinder activity of 7 center of conical surface expansion piece
Connection, guide spiro rod 8 are threadedly coupled after setting cylindrical center's pilot hole above through expansion guide housings 6 with torque nut 5；Lead
Fixed after passing through torque nut 5 to the other end of screw rod 8 by attaching nut 4 and guide rod 2, the centre bore and guiding of counterweight 3
2 outside diameter of bar is slidably matched, and 2 top of guide rod is screwed with fixing nut 1.Wherein, in the conical surface for expanding 6 lower part of guide housings
Footpath and 7 outer circumferential surface sliding fit of conical surface expansion piece, and 4-6 circular arc pawl is split into, expansion guide housings 6 set cylindrical center to lead above
To hole and 8 outside diameter sliding fit of guide spiro rod.When torque nut 5 is in turn on guide spiro rod 8, pull conical surface expansion piece 7 to
On, its conical surface expands outwardly the circular arc pawl of expansion guide housings, will be sleeved on workpiece outside expansion guide housings and expands, smoothly takes
Lower workpiece.Meanwhile counterweight 3 is slided on guide rod 2, Torque-adjusting nut 5 produces disassembling fixture in turn on guide spiro rod 8
Imbalance, avoids workpiece unbalance stress, causes workpiece deflection, causes weak part to be damaged, and ensures that the aviation that is disassembled is attached
Part will not secondary injury.
