The utility model belongs to machining class technology, relates to a kind of matching used bolt disassembling tool, removes the problem that decollation bolt easily destroys center piece body when solving center piece fatigue test.Matching used bolt disassembling tool of the present utility model comprises actuating member and force transmission element; Wherein, actuating member comprises dismounting nut and at least one dismounting joint, and dismounting joint is column, and end, two ends all starts there is screw thread; The screw thread of dismounting nut inner thread and end, described dismounting joint two ends matches; Described force transmission element comprises the force transmitting board in wedge shape.Bolt disassembling tool of the present utility model utilizes screw thread operation principle, is the axis top power of demounting bolt, thus is removed the translating rotation of screw thread by bolt, and structure is simple, easy to operate, can dismantle the central damper bolt of broken end in less space.
Description
Technical field
The utility model belongs to machining class technology, relates to a kind of matching used bolt disassembling tool.
Background technology
Many large, honeycombs are when carrying out the fatigue test of Helicopter Main Hub center piece, and except examining center piece body, damper construction bolt fatigue life is emphasis content of examination equally.
Center piece damper auricle and test load fixture and are connected by damper construction bolt, and in fatigue test process, damper bolt bears larger shearing, can crack, even rupture at dangerouse cross-section place.From result of the test in the past, mainly bolt end cracks and ruptures.Damper construction bolt is when testpieces is installed, and screw-down torque is 180-210Nm, and the spacing of nut and center piece auricle is too small, is inconvenient to dismantle, and needs when dismantling to ensure not produce destruction to center piece body.
Utility model content
The technical problems to be solved in the utility model: propose a kind of matching used bolt disassembling tool, removes the problem that decollation bolt easily destroys center piece body when solving center piece fatigue test.
The technical solution of the utility model:
A kind of matching used bolt disassembling tool, comprises actuating member and force transmission element; Wherein, described actuating member comprises:
At least one dismounting joint, described dismounting joint is column, and end, two ends all starts there is screw thread;
Dismounting nut, the screw thread of internal thread and end, described dismounting joint two ends matches;
Described force transmission element comprises the force transmitting board in wedge shape.
Alternatively, described dismounting joint periphery is provided with the disassembling part identical with described dismounting nut exterior contour.
Alternatively, described force transmitting board comprises dismounting backing plate, stripper, dismounting top board.
The beneficial effects of the utility model: matching used bolt disassembling tool of the present utility model utilizes screw thread operation principle, be the axis top power of demounting bolt by the translating rotation of screw thread, thus bolt is removed, structure is simple, easy to operate, the central damper bolt of broken end can be dismantled in less space.

Detailed description of the invention
Below in conjunction with accompanying drawing, the matching used bolt disassembling tool involved by the utility model is described in further details.
As shown in Fig. 1,2,3,4,5,6, the device of dismounting decollation bolt of the present utility model, comprises actuating member and force transmission element.
Wherein actuating member comprises dismounting nut 6 and at least one dismounting joint 5; Dismounting joint 5 is in column, and end, two ends all starts there is screw thread; Dismounting nut 6 has the internal thread matched with the screw thread of end, dismounting joint 5 two ends.Force transmission element comprises the force transmitting board in wedge shape.Particularly, force transmitting board can comprise dismounting backing plate 2, stripper 3 and dismounting top board 4, can certainly select more quantity as required, such as increase the quantity of stripper 3.
Stripper 3 is usually located between center piece 1 and dismounting top board 4, fits with a surface of dismantling top board 4 with center piece 1 surface respectively and design in two surfaces of dismounting backing plate 2.
Dismounting top board 4 is usually located between stripper 3 and nut 7, and one of them surface of dismounting top board 4 is consistent with the profile of stripper 3 contact surface, all has certain angle, and with its laminating, the surperficial and nut 7 of another of dismounting top board 3 is fitted.
Dismounting backing plate 2 is usually located between center piece 1 and damper bolt 10, and dismounting backing plate 2 upper surface is fitted by center piece profile design and center piece 1 surface, and dismounting backing plate 2 lower surface and dismounting joint 5 are fitted.
Dismounting joint 5 forms screw pair with dismounting nut 6, and dismounting joint 5 one end is that screw thread screws with dismounting nut 6, and the other end is that polished rod contacts with dismounting backing plate 2.
During use, as shown in Figure 4, first by stripper 3 and dismounting top board 4 as between center piece 1 and damper bolt 10, knock dismounting top board 4, damper bolt 10 can not be rotated, rotating nut 7, only to breaking end concordant with damper bolt 10, continue to knock dismounting top board 4, side force is changed into the axial force of bolt.
Continue rotating nut 7, after nut 7 and packing ring 8 depart from damper bolt 10 smoothly, use dismounting backing plate 2 instead, dismounting backing plate 2 and center piece 1 are fitted, regulates the screwing length of dismounting joint 5 and dismounting nut 6, as shown in Figure 5, dismounting joint 5 is contacted with dismounting backing plate 2, dismounting nut 6 contacts with damper bolt 10, rotates dismounting joint 5, slowly ejected by damper bolt 10 with spanner.The quantity of dismounting joint 5 can select the number be applicable to as required, and equally, dismounting nut 6 is determined according to the quantity of dismounting joint 5.When screw can not rotate time, dismounting joint 5 is exited, gets same dismounting joint 5 and contact with damper bolt 10, for spreading provision for disengagement, continue dismounting according to the method described above, until damper bolt 10 and center piece 1 and load fixture 9 and depart from completely.
Matching used bolt disassembling tool of the present utility model utilizes screw thread operation principle, be the axis top power of demounting bolt by the translating rotation of screw thread, thus removed by bolt, structure is simple, easy to operate, the central damper bolt of broken end can be dismantled in less space.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the original prerequisite of the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
