Description
Technical field
The invention belongs to field of flight vehicle design, specifically devises a kind of propeller phase lock mechanism.
Background technology
Conventional aircraft flies in atmosphere, its dynamical system propeller etc. is usually changeless, and diving flies
Machine will not only navigate by water in atmosphere, also navigate by water in water.More than 800 times of the density difference of air and water, becomes diving aircraft in sky
The flow dynamics that gas is neutralized in water differ greatly.Under the conditions of current technology, diving aircraft navigates by water under water and sky
Middle navigation cannot use same set of dynamical system.Therefore for the requirement for meeting to navigate by water with navigate by water in water in the air at the same time, diving
Aircraft needs suitably to change configuration.In view of water takeoff and the requirement of aerial navigation, the propeller for aerial power
When needing to be placed in outside fuselage, and navigating by water under water, which needs to be accommodated in fuselage, to reduce the resistance of underwater navigation
Power.In order to enable propeller to be accommodated in fuselage, it is necessary to which propeller is fixed on a certain phase.
The content of the invention
To solve the above problems, the present invention proposes a kind of propeller phase lock mechanism, meet diving aircraft storage spiral shell
Requirement when revolving paddle to locking screw paddle phase.
Propeller phase lock mechanism of the present invention, guide pin is fixedly mounted on propeller motor;Guide pin is shuttle-type knot
Structure, middle part opposite sides are straight flange, as spacing cooperation side, coordinate with the guide rod of elongation and realize that propeller motor exports
The rotation limitation of axis.Guide rod is driven by start servo driving, and multi-connecting-rod mechanism is driven the rotation of start steering engine output shaft
Movement is changed into linear motion, drives the stretching motion in guide sleeve.
When the upward motion contact of guide rod is to guide pin, driving guide pin rotation, so as to drive spiral shell by machine shaft
Revolve paddle to rotate, when guide rod is bonded with the spacing cooperation side of guide pin, guide pin and propeller stop operating, propeller
Phase is locked.
The advantage of the invention is that:
1st, propeller phase lock mechanism of the present invention, guide rod is not by the shaft of fusiformis guide pin, during start
Without dead point.
2nd, propeller phase lock mechanism of the present invention, it is versatile, it can apply to most motor helical paddle phase locks
It is fixed.
3rd, propeller phase lock mechanism of the present invention, reliable stabilization, lightweight construction are of low cost.

Embodiment
Specifically name is done further to the present invention below in conjunction with the accompanying drawings.
Propeller phase lock mechanism of the present invention, including guide pin 1, motor rack 2, start steering engine 3, pilot sleeve 4, lead
To bar 5 and multi-jointed gear unit 6, as shown in Figure 1.
The guide pin 1 has center section 101, left half 102 and right half 103, as shown in Figure 2.Wherein, it is middle
Part 101 for rectangle up and down side be limited position coordinate side 104, left and right side respectively with 103 phase of left half 102 and right half
Connect.Left half 102 and 103 symmetrical configuration of right half, are the triangle of end taper;Thus it is in fusiformis knot to make overall guide pin 1
Structure.Guide pin 1 is connected by the perforate on 101 center of center section and is installed in the shaft of propeller motor 7;Then
Propeller 8 also is secured in the shaft of propeller motor 7, and make the center section of guide pin 1 about 101 side parallel to
The blade of propeller 8.Above-mentioned propeller motor 7 is supported fixation by the motor support 201 of 2 top design of motor rack, makes spiral shell
7 output shaft of rotation paddle motor is set along horizontal x-axis direction.
3 output shaft of start steering engine is set along space y-axis direction, is fixedly installed in the left and right of 2 lower part of motor rack design
Side sheet room, positioned at 7 lower rear position of propeller motor.
The guide rod 5 is placed in being set along vertical z-axis direction along pilot sleeve 4 for motor rack top installation;Pilot sleeve
4 are located at 7 lower front of propeller motor, and are in 1 position directly below of guide pin.
The multi-connecting-rod mechanism 6 is used for connecting start steering engine 3 and guide rod 5, by multi-connecting-rod mechanism 6 by start steering engine 3
The rotary motion of output shaft is changed into linear motion, drives guide rod 5 to move up and down in pilot sleeve 4.
The multi-connecting-rod mechanism 6 includes steering engine rocking arm 601, first connecting rod 602, second connecting rod 603 and third connecting rod 604.
Wherein, 601 input terminal of steering engine rocking arm is fixedly installed on 3 output shaft of start steering engine;601 output terminal of steering engine rocking arm and first connects
602 input terminal of bar is hinged, and 602 output terminal of first connecting rod is hinged with 603 input terminal of second connecting rod;603 output terminal of second connecting rod with
604 input terminal of third connecting rod is hinged, and 604 output terminal of third connecting rod is hinged with 5 bottom of guide rod.The axis of above-mentioned each articulated shaft
Along the y-axis direction, and wherein 603 center of second connecting rod is connected on 2 lower part side plate of motor rack by shaft, is formed and turned
Dynamic pair.
After propeller 8 stalls, guide rod 5 is driven to move upwards by start steering engine 3,5 upward motion process of guide rod
In, top touches 1 side wall of guide pin first, promotes guide pin 1 to rotate by guide rod 5 at this time, so as to pass through propeller motor
7 shaft drives propeller 8 to rotate.It is subsequently directed to bar 5 to continue to move up, is eventually led to 5 side wall of bar and 1 center section of guide pin
Side wall is close to, and guide pin 1 and propeller 8 stop operating at this time, and 8 phase of propeller is locked, as shown in Figure 3;Propeller at this time
8 blade is along the z-axis direction.In the above process, the movement of guide rod 5 is not by the shaft of guide pin 1, so that in start process
In avoid dead point.
