Abstract
The invention discloses a fixation method for an unmanned helicopter fuselage middle plate. The method includes the steps of: 1. processing an installation boss (9) that can contact the upper side and inner side of rack horizontal pipes (7) to support and fix a middle plate (4) on the same; 2. positioning the upper side and inner side of middle plate (4) and making the left side abut on a rack side pipe (6); and 3. welding the middle plate (4) to the rack (1). The fixation method for the unmanned helicopter fuselage middle plate provided by the invention has the advantages of reasonable design, simple structure, convenient installation, large bearing capacity and strong connection stability.
Description
Technical field
The present invention relates to helicopter parts assembling, in particular it relates in depopulated helicopter fuselage plate fixing meanss.
Background technology
For its power transmission form of single rotor unmanned helicopter and propeller rotational performance are to affect helicopter performance
Deciding factor.Single-rotor helicopter provides lift by main rotor, turns to helicopter by tail rotor.Therefore need to provide
The main shaft of main rotor rotation and indirectly two grades of axles of offer tail rotor rotation.Whether the fixation that can be stable of main shaft and two grades of axles
Decision helicopter flight stability will be connect.
The fixation of main shaft and two grades of axles at present, adopts more and is separately fixed in fuselage ring by different fixed plates
On, thus helicopter fixed plate whether safety and stability be fixed on fuselage ring it is critical that.
The content of the invention
It is an object of the invention to provide in a kind of depopulated helicopter fuselage plate fixing meanss, in the depopulated helicopter fuselage
The fixing meanss of plate are reasonable in design, simple structure, be easily installed, large carrying capacity, connective stability it is strong.
To achieve these goals, the invention provides in a kind of depopulated helicopter fuselage plate fixing meanss, including：
Step 1, formation is processed on the middle plate and can contact with the upside of frame transverse tube and inner side with plate in supporting and being fixed
Installation base；
Step 2, left side is caused on the upside of middle plate and inner side positioning and simultaneously to abut against on frame side pipe；
Step 3, by middle plate weld to frame.
Preferably, middle plate both sides are provided with bevel for welding.
Preferably, it is additionally included in before step 1 in frame and upper plate is installed.
Preferably, one-level bearing saddle bore, secondary bearing seat slot, one-level step and middle plate when in step 1, middle plate is processed
Contact plane and the plane that contacts with middle plate of secondary bearing seat be reserved with installation gap.
Preferably, frame and middle plate are made up of aluminum alloy materials.
Preferably, used in step 3 argon arc welding welding manner.
According to above-mentioned technical proposal, present invention enhances fixation of the middle plate on fuselage ring, what middle plate was processed at twice
Form can ensure that the depth of parallelism and the perpendicularity with middle plate of alignment of shafts axis and two grades of axle central axis.Ensure that aircraft
Flight stability and aircraft service life.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.

Specific embodiment
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that this place is retouched
The specific embodiment stated is merely to illustrate and explains the present invention, is not limited to the present invention.
Referring to Fig. 1, the present invention provides a kind of fixing meanss of plate in depopulated helicopter fuselage, including：
Step 1, on middle plate 4 (as shown in Figure 2) process formation can contact with the upside of frame transverse tube 7 and inner side with prop up
The installation base 9 (as shown in Figure 3) of plate 4 in supportting and being fixed；
Step 2, left side is caused on the upside of middle plate 4 and inner side positioning and simultaneously to abut against on frame side pipe 6；
Step 3, middle plate 4 is soldered in frame 1.
By above-mentioned technical proposal, present invention enhances fixation of the middle plate on fuselage ring, what middle plate was processed at twice
Form can ensure that the depth of parallelism and the perpendicularity with middle plate of alignment of shafts axis and two grades of axle central axis.Ensure that aircraft
Flight stability and aircraft service life.
In the present embodiment, in order that welding effect is more preferable, it is preferable that 4 both sides of middle plate are provided with bevel for welding 8.
In order to optimize erection sequence so that installation process is more smooth, it is preferable that be additionally included in frame 1 before step 1
Upper installation upper plate 2.
In order to the step centerline hole on plate in ensureing after welding, secondary bearing seat slot centrage are symmetrically put down in frame
On face and centering plate perpendicularity, in preferred steps 1 in plate 4 one-level bearing saddle bore, secondary bearing seat slot when processing, under one-level
The plane that bearing block is contacted with middle plate with the contact plane and secondary bearing seat of middle plate is reserved with installation gap.
In order to mitigate the weight of whole depopulated helicopter, preferred frame while frame 1 and middle 4 mechanical strength of plate is ensured
1 and middle plate 4 be made up of aluminum alloy materials.
In order to optimize welding effect, the welding manner of argon arc welding used in preferred steps 3.
The preferred embodiment of the present invention is described in detail above in association with accompanying drawing, but, the present invention is not limited to above-mentioned reality
The detail in mode is applied, in the range of the technology design of the present invention, various letters can be carried out to technical scheme
Monotropic type, these simple variants belong to protection scope of the present invention.
