Referring to Fig. 1, a kind of device of weapon 12 is guided in label 10 total expressions, and the firing line of this weapon is with 14 expressions.Weapon is installed on the bascule 16, and operator 20 seat 18 also is installed on this bascule.The operator wears the helmet 22, is furnished with alignment clamp 24 on the helmet, and its boresight is with 26 expressions.
Bascule 16(comprises weapon 12 and seat 18) be installed at the fixing end 28, the driving mechanism of being made up of two servo motors is used for changing adjustable height and the rotational angle of bascule with respect to base respectively.30 is one of gudgeon among the figure, and bascule 16 then can change its elevation angle when this gudgeon rotates.
In the back of seat 18, a carriage 32 that is fixed together with bascule 16 is arranged, between the carriage 32 and the helmet 22, an angle detection mechanism 34 is arranged, its rear end links to each other with carriage 32, and front end is connected to the behind of the helmet 22.
Referring to Fig. 2-5.Above-mentioned angle detection mechanism 34 comprises that of being positioned at its front end has the connector 36 of low-carbon (LC) steel disk 38 and the connecting rod 40 of an end stretched that extends to carriage 32 from connector 36.Connecting rod 40 is connected respectively on connector 36 and the carriage 32 by first articulated joint 42 and second articulated joint 44.First articulated joint 42 allows connecting rod 40 around mutually perpendicular two hinge axes 46.1 and 46.2 rotations of tying connector 36 mutually, on the position of each hinge axes 46.1 and 46.2, a linear potentiometer 48.1 and 48.2 is installed respectively.As following to set forth, these linear potentiometers are connected with a circuit, so that the electric signal output of the angles of rotating around hinge axes 46.1 and 46.2 corresponding to connecting rod 40 can be provided.Second articulated joint 44 allows connecting rod around mutually perpendicular two hinge axes 50.1 and 50.2 rotations of doing with respect to carriage 32.Equally, this is in a linear potentiometer 52.1 and 52.2 also is installed respectively on each hinge axes 50.1 and 50.2.They provide corresponding to connecting rod 40 and export around the electric signal of hinge axes 50.1 and 50.2 rotational angles respectively.
The line 46.3 of Fig. 3 is datum lines, it with respect to the helmet 22 fixing and parallel (see figure 1) with boresight 26, and line 50.3 also is a datum line, it is fixed with respect to bascule 16, and parallels (see figure 1) with aiming 26.
Articulated joint 42 and 44 layout can make its hinge axes 46.1 and 50.1 always locate at grade, and this plane parallels with the rotation of bascule 16.And articulated joint 42 and 44 layout can make its hinge axes 46.2 and 50.2 always locate at grade again, and this plane parallels with the lifting axis of bascule 16.Hinge axes 46.2 and 50.2 is fixed with respect to connecting rod 40, and parallel each other.This has just simplified control circuit widely, below with reference to Fig. 6 this point is described.
At the neck place of steel helmet 22 near the operator, be fixed with three blocks of permanent magnets 54 with coplane flat pole face, therefore, low-carbon (LC) steel disk 38 can be fixed on the magnet 54 by magnetic.The plane of above-mentioned pole-face is perpendicular to line 46.3, therefore also perpendicular to boresight 26.
Connecting rod 40 and articulated joint 42 and 44 are entangled by a flexible sleeve, and this flexible sleeve can be the corrugated tube of being made by rubber or the airtight layer material of other similar flexible 58.One end of corrugated tube 58 is fixed to connector 36 ends and forms on the end block 60 of a part of connector 36.Its relative other end then is connected on the end block 61, to form a comparatively airtight overcoat.
Two parts of connecting rod 40 can be done telescopic moving relative to one another by shown in Fig. 3 arrow A, but, syndeton between these two parts makes them not do rotation respect to one another around the longitudinal axis of connecting rod, the rotation that the structure of connector 36 then can make dish 38 do with respect to articulated joint 42 around axis 46.3 is shown in Fig. 3 arrow B.This just allows operator's head to do motion fully freely in the scope that connecting rod 40 is reached.
The detailed structure of connecting rod 36 as shown in Figure 4 and Figure 5.End block 60 recited above is made by aluminium or other nonmagnetic substance.Dish 38 has the plane 62 and the frustoconical axle sleeve 63 of annular, and axle sleeve 63 covers does not have friction bearing 64 and 66, and this assembly is clipped together by circlip 68 and gib screw 70, and screw 70 is covered by plastic cap 72.The position of three blocks of magnet 54 when Fig. 5 illustrates said modules and helmet 38 and works in coordination together.
Referring to Fig. 6, pot 48.2 and 52.2 connects together mutually according to back-to-back mode on the circuit, and their vernier is linked on the summing amplifier 74.1.Because pot back-to-back is electrically connected, so the output of summing amplifier 74.1 poor around the angles of hinge axes 46.2 and 50.2 rotations respectively just with respect to connecting rod 40.Therefore, no matter the angles that connecting rod 40 rotates around hinge axes 46.2 and 50.2 how, as long as axis 46.3 and 50.3 is parallel, always the output of summing amplifier 74.1 just equals zero.The output of summing amplifier 74.1 is delivered in the servo power amplifier 78.1 by another summing amplifier 76.1, and servo power amplifier 78.1 is connected to again on the servo motor 80.1 to drive servo motor 80.1.Can make during servo motor 80.1 work on the bascule around of the motion of lifting axis do with respect to base 28.
Summing amplifier 74.1 and 76.1 and first channel 82.1 of power amplifier 78.1 built-up circuits, circuit also has second channel 82.2, and it comprises summing amplifier 74.2 and 76.2 and the power amplifier 78.2 that is connected to servo motor 80.2.80.2 working times of servo motor can make bascule 16 around the motion of rotation do with respect to base 28.The input signal of second channel 82.2 is from not shown among pot 48.1 and 52.1(Fig. 4), layout herein also be to make no matter connecting rod 40 around the rotational angle of hinge axes 46.1 and 50.1 how, as long as axis 46.3 and 50.3 is parallel, the output of summing amplifier 74.2 always equals zero.
Articulated joint 42 and 44 particular topology can realize using two simple and independent channels or control loop, and one is used to control servo motor 80.1, and another then is used to control servo motor 80.2.
No matter when, as long as angle detector 34 detects the skew that any angle is arranged between axis 46.3 and 50.3, one or two servo motor 80.1,80.2 will start, thereby and orders about bascule 16(and make axis 50.3) move according to the side-play amount of angle.If operator's eyes are kept a close watch on the target that weapon will be shot all the time, above-mentioned action will make offset minus to zero.Make in this way, firing line 14 will followed boresight 26.
Summing amplifier 76.1 and 76.2 has one second input 84.1 and 84.2 respectively.This second input comes the operating rod control system, and the operator adjusts the relation of guiding angle and trajectory by this system.
Air can enter or leave the enclosure space that is formed by corrugated tube 58 and end block 61,62 from the opening (not shown) of a qualification on the end block 61 for example, this just might produce damping effect to testing agency 34, so that their too fast motions are played buffer action and avoid resonance problem.
In order to prevent that servo motor 80.1,80.2 from driving weapon and moving down, the connector 36 and the helmet 22 should be taken apart and taken off, a tongue element 86 is installed on connector 36, and like this, the contact of connector or disconnection just depend on whether magnet 54 contacts with low-carbon (LC) steel disk 38.Tongue element 86 is connected on the control circuit 82.1,82.2 by following method, and promptly when magnet 54 separated with dish 38, servo motor 80.1 and 80.2 quit work.
As can be seen, it doesn't matter for the fixed reference coordinate that the work of angular detection and the helmet 22 and weapon are 12, it directly is connected the helmet and bascule 16(weapon is installed in the top of it firmly) between, a benefit is arranged like this, that is to say that any variation of any non-linear and loop gain of control circuit etc. can not influence operating accuracy.Therefore, for example might replace expensive synchronizer, and the precision of device is not influenced by the inexactness of rotation and lifting axis verticality can with cheap pot.
Because linkage interface and boresight 26 that the helmet 22 and angle detection mechanism are 34 are perpendicular, the helmet is easy to unload fast or hangs down new installation and do not influence performance accuracy.When detecting again and structure when being connected on the helmet 22, as long as align with the pole-face of magnet 54 in the plane 62 of dish 38, deviation any rotation or translation does not influence operating accuracy.And, when unloading testing agency 34, the helmet 22 do not need to unscrew with any fastened tools yet, only need simply they to be drawn back mutually when unloading then can.This point is having an accident or other is in emergency circumstances particularly important.
