Abstract
The utility model discloses a kind of airplane horizontal survey ruler head, including connecting rod (4), the different scale of the mountable range in one end of connecting rod (4), connecting rod (4) other end is equipped with universal end (2), universal end (2) is connected with connecting rod (4) by interference fit, and it can be rotated relative to connecting rod (4), universal end (2) top is equipped with cone and installs point, universal end (2) side is additionally provided with 3 cone installations point (1) and extension device (5), extension device (5) top is equipped with the installation point for the cone (3) that can retreat.For the airplane horizontal survey in ruler head, there is separation error between eliminating structure in the part cooperation of tight fit, guarantee that measurement accuracy again can flexible rotating；Replacement length of the scale can realize heterogenous measurement demand；Point is installed using the cone of all directions, measurement point position, angle change can be rapidly adapted to, by extension device and the cone that can retreat, it can be achieved that Point Measurement in small space, deep hole.
Description
Technical field
The utility model belongs to aviation flight test field technology, is related to the big intensity of aircraft and takes a flight test front and back remaining deformation
Measuring tool more particularly to a kind of airplane horizontal survey ruler head.
Background technique
In flight test process, the front and back remaining deformation that needs to take a flight test to aircraft big intensity is measured and is assessed, with
This guarantees safety to monitor strength of aircraft.It takes a flight test in the previous big intensity of aircraft and uses in the remaining deformation measurement process of front and back
Airplane horizontal survey had the following problems with scale: scale Fit Models are single, can not be suitable for heterogenous；The ruler of scale
Head uses spring compression to connect between etalon, and there are sagging risks, and error is caused to increase；Because of measurement point in measurement process
The reasons such as position, peripheral space lead to more difficult arrival measurement point；Because of position reason, it may cause mark related scale and recognize between reader
Angle is excessive, and data is caused to be difficult to read.
Utility model content
In view of the above situation of the prior art, the utility model aim is to provide a kind of airplane horizontal survey ruler head, makes
Scale can it is widely applicable, error is small, read efficiency and to enhance the man-machine performance used to improve to recognize.
The above-mentioned purpose of the utility model is realized by following technical solutions:
A kind of airplane horizontal survey ruler head, including connecting rod, the different scale of one end replacing range of connecting rod, even
The other end of extension bar is provided with universal end, and universal end is connected with connecting rod by interference fit, and can be relative to connecting rod
Rotation, universal end top are axially arranged with measurement cone installation point along connecting rod, and universal end side is additionally provided with 3 surveys
Amount installs point and extension device with cone, and 3 measurements install point with cone and extension device is the setting of 90 degree of interval, prolongs
Long part top is along the direction axially vertical with connecting rod, the installation point equipped with the measurement cone that can retreat.
Further, the extension device is provided with weight loss groove, so as to the weight of alleviator.
Further, universal end and extension device are that all-in-one machine adds.
Further, the advance and retreat for the measurement cone that can retreat are realized by being threadedly engaged.
Structure is eliminated with the part of tight fit cooperates in ruler head, inside ruler head in the airplane horizontal survey of the utility model
Between exist separation error, further ensure measurement accuracy and meet flexible rotating demand again；The first end of ruler is mounted on by replacement
Length of the scale, it can be achieved that heterogenous measurement demand；Point is installed by the measurement cone of ruler head all directions, can quickly be fitted
Measurement point position, angle change are answered, while by extension device and measurement cone can be retreated, it can be achieved that in small space, deep hole
Point Measurement.
Detailed description of the invention
Fig. 1 is the knot for indicating the airplane horizontal survey ruler head of the utility model in the state of installing measurement cone
The schematic diagram of structure.
Specific embodiment
With reference to the accompanying drawing, with reference to specific embodiment, the airplane horizontal survey that the utility model is further described is used
Ruler head.
Fig. 1 schematically illustrates the airplane horizontal survey ruler head of the utility model in the state of installing measurement cone
Structure.As shown, the ruler head includes that connecting rod 4, one end length of the scale that can be spirally connected of connecting rod 4 are replaceable, that is, range
Different scales (not shown in Fig. 1).The other end of connecting rod 4 is provided with universal end 2, and universal end 2 and connecting rod 4 pass through
Interference fit connection, and can be rotated relative to connecting rod 4, universal 2 top of end is axially arranged with measurement cone along connecting rod 4 and pacifies
Decorate position.The side of universal end 2 is additionally provided with 3 measurement cone installation points 1 and extension device 5,3 installations point
1 and extension device 5 be interval 90 degree be arranged.5 top of extension device is along the direction axially vertical with connecting rod 4, equipped with the survey that can retreat
The amount installation point of cone 3 is in the present embodiment to realize the advance and retreat for the measurement cone 3 that can retreat by being threadedly engaged
, when measuring the point in small space or deep hole, can be retreated measurement cone 3 by precession/back-out, to reach measurement point
The advance and retreat that other modes realize the measurement cone 3 that can retreat can also be used in the purpose of position certainly.
In the present embodiment, the extension device 5 is provided with weight loss groove, so as to the weight of alleviator.In addition, in order to add
Work is convenient, and universal end 2 and extension device 5 can be what all-in-one machine added.
Measurement can be standardized production with cone, so as to quick-replaceable, reduce because the abrasion of measurement cone is led
Cause the generation of measurement error.The airplane horizontal survey of the utility model with ruler head when in use, can as the case may be, measurement
It is mounted on from the appropriate installation point selected in each optional installation point of ruler head with cone.
Structure is eliminated with the part of tight fit cooperates in ruler head, inside ruler head in the airplane horizontal survey of the utility model
Between exist separation error, further ensure measurement accuracy and meet flexible rotating demand again.The first end of ruler is mounted on by replacement
Length of the scale, it can be achieved that heterogenous measurement demand, realize from flivver, such as trainer aircraft, general-purpose aircraft to big aircraft, such as bombing
The measurement demand of the heterogenous such as machine, transporter.By as needed, the peace of the measurement cone of universal end all directions is selected
Position, and the universal end of rotation are decorateeed, measurement point position, angle change can be rapidly adapted to, realizes surveyors' staff face face always
Gauger, convenient accurate reading data.In addition, by extension device and measurement cone can be retreated, it can be achieved that in small space, deep hole
Point Measurement, greatly improve service efficiency and man-machine performance.
