Abstract
The utility model is related to a kind of aviation fasteners cubings, including cubing ontology, the cubing ontology includes several piecemeals, it is both provided with arc surface on the piecemeal, the piecemeal both ends are interconnected so that arc surface is surrounded cylindrical space, dismountable connector is connected between the piecemeal, the connector surface is provided with limit protrusion；The utility model has the advantages that：The distance between limit protrusion is set to by calculating the allowable tolerance of fastener, the length of fit of adjusting connector and piecemeal can adjust the internal diameter of cubing ontology, if fastener cannot be inserted into when cubing ontology internal diameter is adjusted to minimum, fastener can be fully inserted into when internal diameter is adjusted to maximum, then fastener opening diameter sizes are qualified, and detection is easy, improve working efficiency, i.e. replaceable various sizes of connector after fixture block is removed, the scope of application is increased.
Description
Technical field
The utility model is related to cubing fields, and in particular to a kind of aviation fasteners cubing.
Background technology
Fastener connection is that aircraft application is most extensive, and most important connection method is also to ensure that aircaft configuration and system base
The premise and basis of this function.Current fastener is mostly rivet, needs to be detected its diameter.
Automatic detection instrument is with high costs at present, and general universal check tool such as slide calliper rule are inconvenient for use, less efficient, therefore,
Need a kind of convenient and general cubing of aviation fasteners.
Invention content
The utility model aim is：A kind of aviation fasteners cubing is provided.
The technical solution of the utility model is：A kind of aviation fasteners cubing, including cubing ontology, the cubing ontology
Including several piecemeals, arc surface is both provided on the piecemeal, the piecemeal both ends are interconnected so that arc surface is surrounded cylinder
Shape space is connected with dismountable connector between the piecemeal, and the connector surface is provided with limit protrusion.
Further：Wearing layer is coated on the arc surface, the wearing layer is nano-ceramic layer or or modified resin
Layer.
Further：The connector is screw, and the piecemeal side is provided with step screw hole, the step screw hole
Central shaft and the piecemeal central shaft it is perpendicular, the step screw hole includes the large diameter hole interconnected and diameter holes,
There are two limit protrusion, one of limit protrusion is located in the large diameter hole, and another for each connector surface setting
It is a to be then located on the outside of the piecemeal.
Further：The length of the large diameter hole is more than the spacing between described two limit protrusions.
Further：The step screw hole side adjacent with piecemeal outer surface is provided with fixture block, and the fixture block is embedded
On the piecemeal, the fixture block is matched with piecemeal to form step screw hole.
Further：The diameter of the connector is less than the thickness of the piecemeal.
Further：It is fixed on the outside of the piecemeal convenient for hand-held handle.
Compared with prior art, the utility model has the advantages that：The distance between limit protrusion is set to by calculating
The length of fit of the allowable tolerance of fastener, adjusting connector and piecemeal can adjust the internal diameter of cubing ontology, if cubing ontology
Fastener cannot be inserted into when internal diameter is adjusted to minimum, and fastener can be fully inserted into when internal diameter is adjusted to maximum, then fastener opening diameter sizes
Qualification, detection is easy, improves working efficiency, removes i.e. replaceable various sizes of connector after fixture block, increase the scope of application.
Description of the drawings
The utility model is further described with reference to the accompanying drawings and embodiments：
Fig. 1 is the stereoscopic schematic diagram of the utility model；
Fig. 2 is the cooperation schematic diagram of screw and step screw hole in the utility model；
Wherein：1, piecemeal；2, arc surface；3, screw；4, limit protrusion；5, step screw hole；6, large diameter hole；7, path
Hole；8, handle；9, fixture block.
Specific implementation mode
Embodiment：In conjunction with Fig. 1 and a kind of aviation fasteners cubing shown in Fig. 2, including cubing ontology, the cubing sheet
Body includes two piecemeals 1, is both provided with arc surface 2 on the piecemeal 1, be coated with wearing layer on the arc surface 2 (does not draw in figure
Go out), wearing layer is nano-ceramic layer in the present embodiment.1 both ends of the piecemeal are interconnected so that arc surface 2 is surrounded cylindrical empty
Between, connector is connected between the piecemeal 1, the connector is screw 3, and the diameter of screw 3 is less than the thickness of the piecemeal 1
Degree.There are two limit protrusions 4 for the setting of 3 surface of screw.
1 side of the piecemeal is provided with step screw hole 5, the central shaft of the step screw hole 5 in the piecemeal 1
Mandrel is perpendicular, and the step screw hole 5 side adjacent with 1 outer surface of piecemeal is provided with fixture block 9, and the fixture block 9 is embedded
On the piecemeal 1, the fixture block 9 is matched with piecemeal 1 to form step screw hole 5.The step screw hole 5 includes mutually being connected
Logical large diameter hole 6 and diameter holes 7, one of limit protrusion 4 are located in the large diameter hole 6, and another is then located at described point
1 outside of block.The length of the large diameter hole 6 is more than the spacing between described two limit protrusions 4.
1 outside of the piecemeal is fixed with convenient for hand-held handle 8.
Operation principle：The distance between limit protrusion 4 is set to by calculating the allowable tolerance of fastener to be detected,
Adjusting screw 3 and the length of fit of piecemeal 1 can adjust the internal diameter of cubing ontology, if cubing ontology internal diameter is adjusted to fasten when minimum
Part cannot be inserted into, and fastener can be fully inserted into when internal diameter is adjusted to maximum, then fastener opening diameter sizes are qualified, remove fixture block 9 then
Screw 3 can be taken out to replacement from piecemeal 1, corresponding screw 3 is replaced for different fasteners, it is applied widely.
Certain above-described embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with this
The people of technology can understand the content of the utility model and implement according to this, and the protection model of the utility model can not be limited with this
It encloses.Any modifications made in accordance with the spirit of the main technical solutions of the utility model should all cover the guarantor in the utility model
