Abstract
The utility model provides an aerial rudder locking device. The appearance of a bottom plate imitates a mounting surface of a steering engine. A threaded hole and a through hole are machined and are placed in the bottom plate. The type and the position of the threaded hole are corresponding to the type and the position of a threaded hole in the mounting surface of the steering engine. The steering engine is installed on the bottom plate through coordination between a bolt and the threaded hole, and the position of the through hole is opposite to the position of a piston rod of the steering engine. A screw thread is arranged at one end of a standard column, and a column section is placed on the other end of the standard column. A connection hole is placed at one end of a column section. The boundary dimension of the connection hole is the same with the boundary dimension of a connection hole of the piston rod of the steering engine, and the connection hole of the column section is connected with a transmission mechanism of the steering engine. One end of the screw thread penetrates through the through hole in the bottom plate and is fixed on the bottom plate through a nut. The length of the standard column determines the locking position of an aerial rudder. The aerial rudder locking device is simple in structure, low in cost and convenient to install.
Description
Technical field
The invention belongs to the assembling field tests, relate to a kind of locking device.
Background technique
In certain Flight Vehicle Structure, steering wheel is installed on the body of cabin, and its piston rod is connected with airvane by driving mechanism.During steering wheel work, its piston rod can move along a straight line, and drives the rotation of airvane by driving mechanism, and the extrusion of steering wheel piston rod has determined the angle of swing of airvane.In the aircraft development stage, need to carry out uncontrolled flight test, to obtain various test parameters.Airvane need to be locked in a certain angular orientation during the uncontrolled flight test, be directly to adopt the steering wheel of fixed piston rod to lock airvane at present.This method needs the steering wheel of supporting special producing, produce and easily cause state of the art chaotic during assembling, and steering wheel is with high costs, and the manufacture cycle is long, brings very large inconvenience to development and the test of aircraft.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of airvane locking device, simple in structure, with low cost, easy for installation.
The technical solution adopted for the present invention to solve the technical problems is: comprise base plate, standard column and screw, nut, the base plate profile is copied the attachment face of steering wheel, be processed with tapped hole and through hole on the base plate, the type of tapped hole and position are corresponding with tapped hole on the steering wheel attachment face, steering wheel is installed on the base by the cooperation of screw and tapped hole, the position of through hole is corresponding with the position of steering wheel piston rod, standard column one end is screw thread, the other end is shell of column, shell of column one end has attachment hole, the boundary dimension of attachment hole is consistent with the attachment hole of steering wheel piston rod, be connected with the driving mechanism of steering wheel, screw thread one end passes the through hole on the base plate, is fixed on the base plate by nut, and the length of standard column has determined the locked position of airvane.
The invention has the beneficial effects as follows: (1) is simple in structure, and is with low cost.Whole device is totally 5 parts and 1 standard piece, and part can adopt common iron processing.And the complex structure of prior art steering wheel is with high costs, is generally some ten thousand yuan.
(2) easy for installation, reliability is high.Apparatus parts quantity is few, and relatively baroque steering wheel is installed more conveniently, and reliability is higher.
(3) with short production cycle.Whole device can be produced and finish in several days, had improved greatly manufacturing efficiency, had shortened the lead time.
Description of drawings
Fig. 1 is the structural representation of airvane locking device;
Fig. 2 is the embodiment schematic diagram of airvane locking device;
Among the figure, 1-nut, 2-standard column, 3-screw, 4-base plate, 5-airvane, 6-cabin body, 7-driving mechanism.
Embodiment
The present invention adopts installation and the Placement of a unit simulation steering wheel, fixes its active part, with reach the simulation steering wheel effect, and the locking airvane.This device is comprised of 3 kinds of structural members and 1 standard piece, and structural member is base plate, standard column and screw, and standard piece is nut, with reference to Fig. 1, respectively their relation and effect is described by function.
Base plate is the attachment face of simulation steering wheel, its profile with reference to steering wheel profile and simplify so that produce and assembling.Be processed with tapped hole and through hole on the base plate, the type of tapped hole and relative position relation are corresponding with tapped hole on the steering wheel attachment face, guarantee that base plate can be installed on the body of cabin smoothly.The position of through hole is corresponding with the position at steering wheel piston rod center, is used for the installation code post.
Standard column is the piston rod of simulation steering wheel, and an end is screw thread, and the other end is shell of column.Be designed with the attachment hole that is connected with driving mechanism at shell of column, the profile of attachment hole is consistent with the attachment hole of steering wheel piston rod with size.The standard column threaded end passes the through hole on the base plate, is fixed on the base plate by nut.The attachment hole center of standard column to the shell of column root apart from the conversion of size by driving mechanism, just can guarantee that airvane is locked in some angular orientations.For the requirement of different airvane locking angular orientations, by the drive connection conversion of driving mechanism, the different length dimension of post can settle the standard.
Screw directly adopts installs the screw that steering wheel is used, and is used for base plate is installed on the body of cabin.
This device using method is: the first step is passed through hole on the base plate with the standard column thread section, then is fixed on the base plate by nut.Second step is that standard column is connected with driving mechanism, and Placement is consistent with the Placement of steering wheel.The 3rd step was installed to base plate on the body of cabin by screw.Whole device has guaranteed the lock state of airvane for being rigidly connected.
The present invention is further described below in conjunction with drawings and Examples.
This embodiment is with reference to Fig. 2.Take certain aircraft as example, driving mechanism is installed on the body of cabin, and an end is connected with airvane, and the other end can be connected with the airvane locking device.This model aircraft requires airvane is locked on the zero-bit position, and the shell of column length that calculates standard column by geometrical relationship is 44mm, and screw thread is defined as M12.Base plate is sized to 110mm * 80mm * 10mm, guarantees to be convenient to install, and enough strength and stiffness are arranged.Through hole on the base plate is φ 12, and the screw of tapped hole and mounting base is M10, and screw length is 130mm.Nut adopts common standard nut M12.The standard column of airvane locking device, will have an end of attachment hole to be connected with driving mechanism by the pin that steering wheel is installed and put in place after base plate is fixing by nut.Then with 3 mounting screws base plate is fixed on the body of cabin.This moment, whole device was in the Complete Bind state, had guaranteed the locking of airvane.
According to the structural type of this aircraft, the shell of column length of standard column is value in 19mm～69mm scope, airvane can be locked in+30 °～-30 ° of angle ranges in the arbitrary position, to satisfy different locking requirements.
This device cost of production is less than 1% of steering wheel, and is with short production cycle, and the installation time shortened in 5 minutes, and installation and check are convenient, and reliability is high.This device used repeatedly at certain model aircraft, and through the flight test checking, satisfied usage requirement.
