Miscellaneous and production batch is small.If according to conventional fixation means design method, the huge number of fixture will be caused, bad adaptability,
Cost increases and management difficulty is big.
Utility model content
The technical problem that the utility model solves is, there is provided a kind of restructural, the adjustable ground plane repeated
Test model sheet metal part covering screw rod fixing device, while labour cost is reduced, improves ground plane test model
The efficiency of covering positioning.
The utility model is to be achieved through the following technical solutions：
A kind of ground plane test model sheet metal part covering screw rod fixing device, including it is fixed on determining for covering outer surface
Position support and the locating rod that is positioned to covering and skeleton, several are offered on described locating support crossbeam and supplies locating rod
The positioning hole passed through, locating rod are inserted into the rivet hole reserved on covering after passing through positioning hole.
Described locating support is made of δ=10mm aluminum component, and positioning hole is the φ 8 drilled on aluminum component bolt hole.
Interval between described positioning hole and positioning hole is at least maintained within 20mm.
Described locating rod is screw rod, and the bottom of locating rod is round end.
Described locating rod bottom is provided with the protective layer for preventing that covering is destroyed.
Described locating rod bottom is provided with the elastic protective layer for preventing that covering is destroyed.
Described elastic protective layer is rubber blanket or rubber ring.
Compared with prior art, the utility model has technique effect beneficial below：
Ground plane test model sheet metal part covering screw rod fixing device provided by the utility model, restructural, can be weighed
Polyphony section uses, and substantial amounts of time and cost is saved, without design iterations, strong applicability, while labour cost is reduced
Improve the efficiency of ground plane test model covering positioning.
Meanwhile the ground plane test model sheet metal part covering screw rod fixing device, more positioning can meet outside covering
The feature of shape, and only need to change the locus of support covering, it is possible to skin shape is positioned in diverse location, to covering
Surface is reserved rivet hole and riveted, and the screw rod fixing device of covering provides for more preferable positioning action.
Brief description of the drawings
Fig. 1 illustrates for ground plane test model sheet metal part covering screw rod fixture structure provided by the utility model
Figure.
Wherein, 1 is locating support；2 be locating rod；3 be positioning hole；4 be covering.
Embodiment
The utility model is described in further detail with reference to specific embodiment, described is to the utility model
Explanation rather than restriction.
Referring to Fig. 1, a kind of ground plane test model sheet metal part covering screw rod fixing device, including be fixed on outside covering
The locating support 1 on surface and the locating rod 2 positioned to covering and skeleton, if being offered on the described crossbeam of locating support 1
The dry positioning hole 3 passed through for locating rod, locating rod 2 are inserted into the rivet hole reserved on covering after passing through positioning hole.
Wherein, described locating support 1 is made of δ=10mm aluminum component, and positioning hole is the φ 8 drilled on aluminum component spiral shell
Keyhole.Interval between described positioning hole and positioning hole is at least maintained within 20mm, and described locating rod 2 is screw rod, fixed
The bottom of position bar is round end.
Further, the described bottom of locating rod 2 is provided with the protective layer for preventing that covering is destroyed, the so circle when screw rod
When head contacts with the rivet hole reserved on covering, covering can be prevented to be damaged or destroy.
It should be noted that the described bottom of locating rod 2 is provided with the elastic protective layer for preventing that covering is destroyed.Specifically
Described elastic protective layer is rubber blanket or rubber ring.
Specifically, due to covering blank after drawing and forming, it is necessary to the edge of covering 4 is removed, it is and pre- on covering
Rivet hole is stayed, the covering screw positioning device of the utility model research will enter screw rod and covering and skeleton during covering
Row positioning, the utility model, according to the profile and piecemeal of covering, can all be positioned with screw rod and filled using more positioning methods
Put positioning.
On the locating support that it is δ=10mm by aluminum component that ground plane test model sheet metal part covering screw rod fixing device, which is,
Drill φ 8 bolt hole, profile is positioned according to the profile difference of ground aircraft testing model, profile according to model not
Together, cutting profile uses NC laser cutting, and precision is accurate.
In operation, the most accurate mode of use is positioned by profile, according to the different sprocket bits of profile in position fixing process
Put, the interval of each positioning hole is at least maintained within 20mm, it is ensured that the covering at each position preferably can suit with skeleton
Complete, meet the theoretical profile of ground experiment model.
The purpose of this utility model is exactly on the basis of covering manufacture installation, develops a set of can be used for zero in riveting process
Part positioning, indeformable and adjustable screw device.Ground plane test model sheet metal part covering provided by the utility model
Screw rod fixing device, restructural, repeatable regulation use, and substantial amounts of time and cost are saved, without design iterations, applicability
By force, the efficiency of ground plane test model covering positioning is improved while labour cost is reduced.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
