Standby corresponding performance parameter.In existing rotary expansion wing plate ground-testing plant, electrodynamic analogy is not yet set and launches dress
Put.In the early stage of ground-testing plant is debugged, rotate by folded state when storing merely with manually completing wing plate
The work of deployed condition when expanding into normal work, therefore, during the combined test of ground-testing plant, deposits
In many deficiencies:
The most it is not provided that the kinestate of continuous-stable, it is impossible to realize the dynamic debugging of ground-testing plant；
2., in the debugging stage, the data discrete that test obtains is excessive, and cannot reappear；
3. the cycle of equipment combined test is long, inefficiency.
According to interconnection internet retrieval result, do not find the rotary expansion wing plate ground-testing plant electrodynamic analogy of similar structures
Expanding unit.

In order to overcome the deficiencies in the prior art, the present invention provides a kind of rotary expansion wing plate ground-testing plant electrodynamic analogy
Expanding unit, solves the combined test problem of rotary expansion wing plate ground-testing plant, optimizes the overall performance of equipment,
Reduce experimentation cost, improve the technical-economic index that equipment runs.
The technical solution adopted for the present invention to solve the technical problems is: include slider-crank mechanism O 〃 BA and trans
Four-bar mechanism O ＇ CBO 〃, described slider-crank mechanism O 〃 BA using hinge O 〃 as the fixing centre of gyration,
Described trans four-bar mechanism O ＇ CBO 〃 is using hinge O ＇ as the centre of gyration, and hinge O ＇ still rotates exhibition simultaneously
Open the centre of gyration of wing plate；Servomotor drives slide block A to move along the rail by feed screw nut, and slide block A passes through connecting rod
AB drives the crank BO 〃 of slider-crank mechanism to rotate around centre of gyration O 〃, and crank BO 〃 passes through hinge B with anti-
The connecting rod BC of formula four-bar mechanism connects, and then drives rocking bar CO ＇ D to rotate around centre of gyration O ＇, rocking bar CO ＇
D drives wing plate drive pin to rotate around centre of gyration O ＇, by wing plate rotary expansion to operating position by hinge D.
The invention has the beneficial effects as follows:
1) wing plate that can provide continuous-stable launches kinestate, conveniently realizes the dynamic debugging of equipment；
2) the test data stabilization that commissioning device obtains, repeatability is preferably；
3) compared with the dynamic debugging carried out with product, simplify debugging routine, reduce debugging cost；
4) shortening the combined test cycle of equipment, work efficiency is improved.

Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings, and the present invention includes but are not limited to following embodiment.
This device is arranged on rotary expansion wing plate ground-testing plant, utilizes driven by servomotor, by the rotary expansion wing
Plate is by the deployed condition that collapsed state when storing is normal work.
As it is shown in figure 1, the principle sketch of rotary expansion wing plate ground-testing plant electrodynamic analogy expanding unit, hinge O ＇,
O 〃 is two fixing centres of gyration of device, and this device is by slider-crank mechanism O 〃 BA and trans four-bar mechanism O ＇
CBO 〃 combines.When servomotor (not marking in figure) drives slide block A by feed screw nut, along guide rail H-H
Move along a straight line from left to right, by A0Move to A1Time, drive crank BO 〃 along counterclockwise around revolution through connecting rod AB
Center O 〃 rotates, and crank BO 〃 is connected with connecting rod BC by hinge B, and drives rocking bar CO ＇ D along clockwise
Rotate around centre of gyration O ＇, then driven wing plate drive pin to rotate around centre of gyration O ＇ by hinge D, wing plate is rotated
It is expanded to operating position.Centre of gyration O ＇ is the centre of gyration of rotary expansion wing plate.Letter mark subscript 0 generation in figure
The meter apparatus initial position when wing plate is in folded state, subscript 1 represents device when wing plate is in deployed condition
Final position.
Debugging needs according to equipment, by changing the control parameter of servomotor, slide block A can obtain different fortune
Row state and velocity variations rule, thus wing plate obtains corresponding running status when rotary expansion.
Running state parameter when master control system is by the wing plate rotary expansion loading rule parameter different from charger is entered
After row is appropriately combined, ground-testing plant is achieved with testing required various service datas.
The relation of each assembly relevant parameter:
The length of connecting rod: CO ＇=B O 〃
As it is shown in figure 1, this device uses the drive system that two kinds of four-bar mechanisms combine, the input of mechanism, output
Having uniqueness, the designing points of Tu Zhong mechanism each several part is described below:
1) structure of hinge is connected: as in figure 2 it is shown, hinge pin axial limiting mode uses split-type shaft block ring to tie
Structure, such as patent 201420503997.6 disclosure of that.
2) electrodynamic analogy expanding unit is combined by slider-crank mechanism O 〃 BA and trans four-bar mechanism O ＇ CBO 〃
Forming, the straight-line displacement input of slide block A becomes monotropic function between exporting with wing plate rotary expansion angle, i.e. corresponding position
Shifting relation has uniqueness.
3) ball screw assembly, of slide block A is driven to bear tension in the working region of wing plate rotary expansion.
The mechanism size of the embodiment of the present invention is as follows:
Centre of gyration O ＇ is the centre of gyration of rotary expansion wing plate.
The relative position of the connecting rod centre of gyration: X=310, Y=360.
Length of connecting rod: CO ＇=B O 〃=205mm, BC=353.6mm, BC=370mm, DO=82mm.
The relevant parameter that device is chosen is:
Slide block A stroke: A0A1=370mm；
Rocking bar CO ＇ D corner: ∠ C0O ＇ C1=90 °；
Hinge pin between connecting rod: diameter phi 25, axial limit structure uses split-type shaft block ring patent；
The feed screw nut of driving slide block A is: ball screw assembly, FF5010-5.
