Description
Technical field
The utility model is related to helicopter parts mounting technology field, and in particular to a kind of tail-rotor main shaft of helicopter is auxiliary
Help positioning target.
Background technology
In the assembling process of helicopter, the connection main shaft of tail-rotor and fuselage must be carried out when installing axle centralized positioning to prevent
Center deviation.The positioning of calibration elsewhere in current helicopter assembling typically uses angle iron, centrally disposed in angle iron
It is red, be aligned red point on the center and angle iron that need to calibrate during calibration to realize positioning, the red point at angle iron center compared with
Greatly, difficulty is larger when calibration is installed, and the installation place of tail-rotor main shaft is not particularly suited for the installation of angle iron, when positioning here
Specific purpose tool is there is no at present, it is too high to the mounting technology skill requirement of assembly crewman.
In the prior art, Patent No. ZL201520700359.X utility model patent and application publication number is
CN105127937A application for a patent for invention, the consistent title of content is《A kind of positioning target of copter engine》, it is public
The auxiliary positioning target that a kind of helicopter is used when installing engine has been opened, but the main shaft installation position of helicopter tail rotor is with sending out
Motive difference is very big, and the structure design of the prior art is applied to the rotational positioning of engine center axle and is not suitable for vertical flat
Face is positioned, it is impossible to solve the problems, such as the plane positioning faced when tail-rotor main shaft is installed.
Utility model content
The purpose of this utility model aims to provide a kind of tail-rotor main shaft auxiliary positioning target of helicopter, overcomes prior art
Deficiency, realize fast and accurately plane positioning in helicopter tail rotor main shaft installation process.
To achieve the above object, the tail-rotor main shaft auxiliary positioning target of a kind of helicopter of the present utility model, including install
Seat, center target and battery case, mounting seat are integrally set to " ⊥ " type, the centrally disposed through hole of mounting seat, on mounting seat is positive
Portion sets mounting groove, and the left and right ends of mounting seat set mounting hole in vertical direction, and center target is fixedly installed in mounting seat
In central through hole, one side of the center target with target center scale is placed in the front of mounting seat, and battery case is fixedly installed on mounting seat
In the mounting groove of front upper, the power switch of battery case is arranged at the upper rear portion of mounting seat, and center target is provided with backlight, in
The backlight of heart target is electrically connected with battery case, and backlight can illuminate the target center scale of center target when opening.
In use, mounting seat bottom is put at the installation calibrating of tail-rotor main shaft, mounting seat is parallel with mounting surface and target center
With the center superposition of main shaft installation place, mounting seat is fixed by the mounting hole of mounting seat both sides, battery case power switch is opened,
Light target center and carry out the positioning calibration of tail-rotor spindle eccentricity.
A kind of tail-rotor main shaft auxiliary positioning target of helicopter of the present utility model has have as follows compared with prior art
Beneficial effect：Mounting seat is integrally set to " ⊥ " type and sets mounting hole in left and right ends vertical direction so that mounting seat can fix perpendicular
Directly be installed at the tail-rotor main shaft installation calibrating of helicopter, the design of backlight center target cause target center it is bright be easy to observation and
Calibration positioning, so as to solve the problems, such as that the plane positioning that helicopter tail rotor main shaft is installed provides a kind of specific purpose tool, improve
Assembling accuracy and efficiency of assembling.

Describe in detail.
The tail-rotor main shaft auxiliary positioning target of helicopter shown in Fig. 1, Fig. 2, including mounting seat 1, center target 2 and battery
Box 3, mounting seat 1 is overall to be set to " ⊥ " type, and the centrally disposed through hole of mounting seat 1, the positive top of mounting seat 1 sets mounting groove 4,
The left and right ends of mounting seat 1 set mounting hole 5 in vertical direction, and center target 2 is fixedly installed in the central through hole of mounting seat 1
In, one side of the center target 2 with target center scale is placed in the front of mounting seat 1, and battery case 3 is fixedly installed on the front of mounting seat 1
In the mounting groove 4 on top, the power switch 6 of battery case 3 is arranged at the upper rear portion of mounting seat 1, and center target 2 is provided with backlight,
The backlight of center target 2 is electrically connected with battery case 3, and backlight can illuminate the target center scale of center target 2 when opening.
In use, the bottom of mounting seat 1 is put at the installation calibrating of tail-rotor main shaft, mounting seat 1 is parallel with mounting surface and target
The heart and the center superposition of main shaft installation place, mounting seat 1 is fixed, turn on the power switch 6 by the mounting hole 5 of the both sides of mounting seat 1,
