Abstract
One kind be the utility model is related in aircraft assembling process, realize and determine power instrument and the adapter of bolt and nut switching, the adapter, include link body (2), the both ends of the link body (2) are connected by bolt (4) and nut (5) with one end of link rod head (1) and connecting rod afterbody (3) respectively, the other end of the link rod head (1) coordinates with determining the cooperation of power instrument, the other end of the connecting rod afterbody (3) with the nut of pending pretension.The utility model with determining power Tool Room in nut by adding a fixable movable rod, the various angles being adapted with construction space can be converted rapidly, will be unable to determining that power instrument directly carries out pretension, the position of determining power is connected by connecting rod, exclude because construction space influence to carry out determining power the problem of.
Description
Technical field
A kind of switching device is the utility model is related to, more particularly to one kind, in aircraft assembling process, power instrument is determined in realization
With the switching device of bolt and nut switching.
Background technology
During aircraft manufacturing, it is to be bolted to have many positions, realizes its tension or shearing resistance stress.In order to protect
The fatigue strength of fuselage is demonstrate,proved, the stress of bolt must be uniform, so to carry out pretension to the bolt of installation, determine power (herein
Determine power to refer to：During aircraft manufacturing, the nut tightened is unclamped, power instrument is determined on request or comes to an agreement torque wrench
On force value, determine the arm of force of torque wrench by rotating, tighten nut with power wrench is determined, the operation untill hearing prompt tone).
At present, pretension is carried out to the bolt of installation, determining the length of the arm of force of the general power of determining instrument of power, to be only applicable to construction part open,
And without the position at any turning, still, many position construction spaces of fuselage are narrow and small, power instrument determined using general, it is difficult to complete
Into the narrow and small position of fuselage bolt and nut pretension and determine masterpiece industry.
Utility model content
In order to overcome the shortcomings of that the existing general power of determining instrument can not directly carry out nut pretension, determine power, the utility model carries
For a kind of adapter for changing pretension, determining power path, wanted with meeting the bolt and nut pretension at the narrow and small position of fuselage and determining masterpiece industry
Ask.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions：
A kind of adapter, comprising link body, the both ends of the link body are respectively by screw bolt and nut, with connecting rod head
Portion connects with one end of connecting rod afterbody, the other end of the link rod head and determine power instrument coordinate, the connecting rod afterbody it is another
End and the nut of pending pretension coordinate.
Further, the load partial cross sectional of the link rod head, link body and connecting rod afterbody is rectangle, is connected
Position connects for slotting ear formula, to better ensure that at work, can bear larger torsional forces.
Further, the link body is made up of two or more connected root connecting rods, so as to according to practical operation
Situation increases or shortened the length of adapter.
Further, the material of the link rod head, link body and connecting rod afterbody is 45# steel quenched materials, to ensure
With enough intensity.
Compared with prior art, the beneficial effects of the utility model are：By nut and determine power Tool Room add one can
Fixed movable rod, the various angles being adapted with construction space can be converted rapidly, will be unable to determining torque wrench or determine power work
The position that tool directly carries out pretension, determine power is connected by connecting rod, exclude because construction space influence to carry out determine power the problem of, conveniently soon
The pretension of the bolt and nut during aircraft manufacturing is completed promptly, determines power.The device simple installation, low cost, improving effect
While rate, reliable and stable operation is formed, reduces labor intensity.
Brief description of the drawings
Fig. 1 is the schematic diagram according to adapter of the present utility model.
Embodiment
Below with reference to the accompanying drawings, in conjunction with specific embodiments, adapter of the present utility model is described in further detail.
Fig. 1 is schematically illustrated according to adapter of the present utility model.As shown in fig. 1, adapter bag of the present utility model
Containing link body 2, the both ends of the link body 2 pass through the one of bolt 4 and nut 5 and link rod head 1 and connecting rod afterbody 3 respectively
End connection, the other end of the link rod head 1 coordinate with determining power instrument, for example can be inserted into box spanner or determine power instrument, described
The nut of the other end of connecting rod afterbody 3 and pending pretension coordinates, such as available for the collet head for installing nut or for installing
Four square bars of collet head.Box spanner determines power instrument applying power and passes to adapter, and the power that adapter is subject to passes to spiral shell again
Bolt nut.When construction space changes, by bolt 4 and nut 5, link rod head 1, link body 2 and connecting rod tail can be made
Portion 3 is transformed into rapidly the different spaces state being adapted with construction space, so as to realize the pretension of nut, determine power.In addition, connecting rod
Head 1, connecting rod afterbody 3 can carry out replacement of different sizes.
The load partial cross sectional of the link rod head 1, link body 2 and connecting rod afterbody 3 is rectangle, and connected position is
Slotting ear formula connects, and to better ensure that at work, can bear larger torsional forces.
The link body 2 can be made up of two or more connected root connecting rods, so as to be increased according to practical operation situation
Add or shorten the length of adapter.
The material of the link rod head 1, link body 2 and connecting rod afterbody 3 should have higher intensity, and preferably 45# steel is quenched
Fiery material.
In the present embodiment, bolt 4 and nut 5 be not less thanTighten screw bolt and nut.
For example, when the bolt to fuselage key position carries out determining power, the position of bolt is in fuselage into the angle less than 90 °
Position, it is front and rear less than there is other parts at 500mm, determine torque wrench and can not realize to determine power with general, now, from the utility model
Adapter, by the switching of connecting rod, guide the one end being connected with determining torque wrench into open position, bolt carried out to determine power.
Claims (4)
1. a kind of adapter, comprising link body (2), the both ends of the link body (2) pass through bolt (4) and nut respectively
(5) one end with link rod head (1) and connecting rod afterbody (3) is connected, and the other end of the link rod head (1) is matched somebody with somebody with determining power instrument
