Description
Technical field
The utility model belongs to aircraft manufacturing mounting technology field, relates to a kind of rivet pruning length of measuring and cuts.
Background technology
Aircaft configuration is in assembling process or in Flight Line Maintenance process, and riveting method is the mode often used.Due to the accumulation of finished parts thickness deviation, or surface roughness affect, or the impact of fit-up gap, sometimes the length of rivet of erecting yard is much larger than union piece thickness, need, by pruning the length of rivet, to ensure that manufactured head is unlikely to oversize too greatly, guarantee riveting quality.Therefore need a kind of rivet easy to use of design to cut, allow assembly crewman can prune the length of rivet as required quickly and easily.
Summary of the invention
In order to solve the problem, the utility model provides a kind of rivet pruning length of measuring to cut.The technical scheme of this utility model is: a kind of rivet pruning length of measuring is cut, comprise left handle, right handles, upper shearing rotating disk, down cut rotating disk, shear through hole, stop ledge, loose slot and fixed axis, left handle and down cut rotating disk connect together, right handles and upper shearing rotating disk connect together, upper down cut rotating disk is shaped with the shearing through hole of corresponding different-diameter, its size and conventional various rivet are directly through corresponding, minimum straight warp is 2.5mm, maximum straight warp is 6mm, upper down cut center of turntable is hinged by fixed axis, it is characterized in that: described upper shearing rotating disk thickness is 1mm, described down cut rotating disk thickness is 2mm, the thickness of upper down cut rotating disk is as the gage shearing the length of rivet.Described upper down cut disk edge is provided with stop ledge and loose slot mutually, and the stop ledge of a shearing rotating disk moves in the loose slot that another shears rotating disk, the opening angle that restriction rivet is cut.
The utility model structure is simple, easy to use, and assembly crewman can prune the length of rivet quickly and easily as required.
Accompanying drawing explanation
Fig. 1 is the utility model external form figure.
Fig. 2 is the utility model structure chart.
In figure: 1-left handle, 2-right handles, 3-shears rotating disk, 4-down cut rotating disk, and 5-shears through hole, 6-stop ledge, 7-loose slot, 8-fixed axis.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
As accompanying drawing 1, shown in 2, a kind of rivet pruning length of measuring is cut, comprise left handle 1, right handles 2, upper shearing rotating disk 3, down cut rotating disk 4, shear through hole 5, stop ledge 6, loose slot 7 and fixed axis 8, left handle 1 and down cut rotating disk 4 connect together, right handles 2 and upper shearing rotating disk 3 connect together, upper down cut rotating disk 3, the shearing through hole 5 of corresponding different-diameter is shaped with on 4, its size and conventional various rivet are directly through corresponding, minimum straight warp is 2.5mm, maximum straight warp is 6mm, upper down cut rotating disk 3, 4 centers are hinged by fixed axis 8, described upper shearing rotating disk 3 thickness is 1mm, described down cut rotating disk 4 thickness is 2mm, all components are by 30CrMnSiA steel making.The failure by shear load of the LY10 aluminium rivet of diameter 6mm is 6965N, and the singlehanded grip of operator can reach 200N, so should be greater than 35 to the distance at fixed axis 8 center and shearing through hole 5 center to the ratio of the distance at fixed axis 8 center bottom left and right handle 1,2.When pruning rivet, rotate left and right handle 1, 2 make two shearing rotating disks 3, shearing through hole 5 on 4 aligns, the rivet needing to shear is loaded the through hole corresponding with rivet diameter, if desired the length of rivet of 1mm is cut off, then by rivet tail end with 1mm thickness is sheared rotating disk 3 outer surface and aligns, firmly rotate left and right handle 1, 2, the length of rivet can be cut off 1mm, if desired the length of rivet of 2mm is cut off, then rivet tail end is alignd with 2mm thickness down cut rotating disk 4 outer surface, firmly rotate left and right handle 1, 2, the length of rivet can be cut off 2mm, if desired other length are cut off, 1mm and 2mm length by shearing varying number is respectively carried out combination and is realized.
