Description
Technical field
The utility model belongs to Aviation Test frock clamp field, relates to a kind of device for disk spring rigidity rating test.
Background technology
At undercarriage, fall, in shimmy test, some testing requirements Reality simulation fuselage mode and the local rigidity of supporting, this just needs application simulation device simulation rigidity, contain a lot of different size disk springs, and most of criteria of right and wrong part needs processing in simulator.And disk spring is after processing, need in Material Testing Machine, to each disk spring, carry out rigidity demarcation, owing to there is no the caliberating device of special-purpose fixedly disk spring in Material Testing Machine, at timing signal, easily there is bias in disk spring, the rigidity test data of measuring have error, be difficult to warranty test quality, and install take a lot of work, time-consuming, inefficiency.
Utility model content
The purpose of this utility model: a kind of easy adjusting, disk spring rigidity rating test device that precision is higher are provided.
The technical solution of the utility model: a kind of disk spring rigidity rating test device, it comprises circular upper bed-plate, circular lower bottom base, locating shaft, wherein, the cylindrical section part of circular upper bed-plate and circular lower bottom base is connected with lower chuck with the upper chuck in Material Testing Machine respectively, described locating shaft is positioned in the middle of circular upper bed-plate and circular lower bottom base, on axis in the two cylindrical section, and disk spring is positioned at the pilot hole place of circular lower bottom base by locating shaft.
The beneficial effects of the utility model: the utility model disk spring rigidity rating test device is by changing the locating shaft of different size, can realize a covering device rigidity demarcation that just can complete plurality of specifications disk spring is once installed in Material Testing Machine, for the rigidity of disk spring in demarcation, occur and computational data error amount larger, can find in time and do rational adjustment.This device can make the trueness error of disk spring rigidity test be reduced in 3% by 10% original left and right, to guarantee the high-quality test that completes.The utility model has not only improved the precision of disk spring rigidity test but also has improved work efficiency, also has compact conformation, easy to use, the feature of low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Structural representation when Fig. 2 is the utility model work.
Wherein, the circular upper bed-plate of 1-, 2-locating shaft, the circular lower bottom base of 3-, 4-butterfly spring, 5-upper chuck, 6-lower chuck.
Embodiment
Below by embodiment, the utility model is described in further detail:
Refer to Fig. 1, it is that the utility model is for the apparatus structure schematic diagram of butterfly spring rigidity rating test.Described disk spring rigidity rating test device comprises circular upper bed-plate 1, circular lower bottom base 3, locating shaft 2, wherein, the cylindrical section part of circular upper bed-plate 1 and circular lower bottom base 3 is connected with lower chuck 6 with the upper chuck 5 in Material Testing Machine respectively, to guarantee the location of disk spring 4 in Material Testing Machine.Described locating shaft 2 is positioned in the middle of circular upper bed-plate 1 and circular lower bottom base 3, and on the axis in the two cylindrical section, disk spring 4 is positioned at the pilot hole place of lower bottom base 2 by locating shaft 2.
Described locating shaft 2 is made into multiple different specification according to the specification of butterfly spring.
It is motionless that the circular upper bed-plate 1 of the utility model timing signal and circular lower bottom base 3 are connected with Material Testing Machine, only need can realize the covering device rigidity that once installation just can complete plurality of specifications disk spring in Material Testing Machine by the locating shaft of replacing different size and demarcate.For the rigidity of disk spring in demarcation, occur and computational data error amount larger, can find in time and do rational adjustment.This device can make the trueness error of disk spring rigidity test be reduced in 3% by 10% original left and right, to guarantee the high-quality test that completes.The utility model has not only improved the precision of disk spring rigidity test but also has improved work efficiency, also has compact conformation, easy to use, the feature of low cost of manufacture.
