Abstract
The utility model provides a pointer type analogue instrument with eccentric driving. A driving catch plate is fixedly connected with the rotating shaft of a stepping motor, a driven catch plate is positioned on the driving catch plate, a sliding pin is fixed on the driving catch plate and inserted into the radial slideway of the driven catch plate, and the sliding pin drives the driven catch plate to rotate; an elastic friction device is arranged between the driving catch plate and the driven catch plate; a dial plate or a pointer is fixed on the central axle of the driven catch plate through a push pin and rotates along with the driven catch plate; an anti dazzling screen is fixedly installed on the central axle of the driven catch plate through a nut and rotates along with the driven catch plate; a photoelectric coupler is fixedly installed on a casing and corresponds to the position where the anti dazzling screen passes through. The photoelectric coupler is adopted to perform zero point detection to the pointer of the instrument, and the pointer can return the zero point according to the requirement. The pointer type analogue instrument has the advantages of low cost, high indication precision, repeated positioning of the pointer, and complete analogue functions.
Description
Technical field
The utility model is the improvement to existing pointer analogue instrument structure, a kind of pointer analogue instrument of eccentric driving is provided, be used for the repacking of various delivery vehicles (as aircraft, vehicle, tank, naval vessel etc.) emulation instrument, belong to the technology of instrument and meter field.
Background technology
In the training simulators technical field of delivery vehicle, the major tasks that passenger cabin (pilothouse) equipment simulating is, and passenger cabin (pilothouse) equipment is based on pointer instrument.Because driver's work habit, they prefer and the training simulators of being ready to accept to be equipped with the pointer instrument identical with real equipment.
On the existing driving simulator, the driving method that pointer analogue instrument is reequiped has: differential synchronizer driving, the driving of direct current generator servomechanism, the driving of alternating current generator servomechanism and step motor drive etc.In these modes, direct current and alternating current generator servomechanism type of drive are simple in structure, but higher to the accuracy requirement of analog drive signal, and simultaneously the index error of gauge pointer is bigger, and stepper motor can be realized open loop control, are easier to the interface ratio of computing machine.But also there is following problem: owing to the location and installation second time, be difficult to determine positioning reference, cause the disalignment of motor and needle pivot, cause rotation friction to increase, the step phenomenon occurs falling.Each double action (driving again) starting need be readjusted zero-bit.
Summary of the invention
The utility model provides a kind of pointer analogue instrument of eccentric driving, has solved that the pointer analog meter complex structure of existing repacking, repacking cost height, pointer precision are low, pointer resets problems such as difficulty.
Technical solution of the present utility model is as follows: initiatively dial is fixedlyed connected with the stepper motor rotating shaft, passive dial is located on the active dial, initiatively be fixed with sliding pin on the dial, sliding pin is inserted in the radial groove of passive dial, drives passive dial by sliding pin and rotates; Between active dial and passive dial, the elastic-friction device is housed; Dial plate or pointer are fixed on by thimble on the central shaft of passive dial, together rotate with passive dial; Being fixed with anti-dazzling screen by nut on the central shaft of passive dial also together rotates with passive dial; On the optocoupler fixed installation housing, corresponding with the position that anti-dazzling screen passes through.
The utility model removes true instrument impression part and gear train, drives the gauge pointer central shaft with stepper motor by dial, between active dial and passive dial the elastic-friction device is housed, and adopts photoelectrical coupler to finish indicator and return zero the detection.
Good effect of the present utility model is: adopt the method for stepper motor by dial driving gauge pointer central shaft, the excessive stepper motor that causes of second positioning mismachining tolerance falls the step when solving the instrument repacking, and then makes indicator rotate the difficult problem of inequality; Employing is equipped with the elastic-friction device between active dial and passive dial, solved the gap causes between sliding lock and the chute gauge pointer Rotation With Changing to the time the small problem of beating that occurs; Adopting photoelectrical coupler that the instrument indicator is carried out zero-bit detects, solved each double action (again drive) starting and need readjust the problem of zero-bit, thus developed successfully that cost is low, pointing accuracy is high, can resetting, pointer analogue instrument that analog functuion is complete.

Embodiment
As shown in Figure 1, the utility model is made of stepper motor 1, active dial 2, jackscrew 3, sliding pin 4, elastic-friction device 5, passive dial 6, nut 7, pointer 8, thimble 9, anti-dazzling screen 10, optocoupler 11, wherein, stepper motor 1 rotating shaft is fixedlyed connected by jackscrew 3 with active dial 2, on active dial 2, be fixed with sliding pin 4, sliding pin 4 is inserted in the radial groove of passive dial 6, drives passive dial 6 by sliding pin 4 and rotates.If when initiatively dial 2 did not overlap with passive dial 6 axis, sliding pin 4 can radially slide in the radial groove of passive dial 6.Between active dial 2 and passive dial 6, elastic-friction device 5 is housed, in order to eliminate Rotation With Changing to the time the small of indicator beat.Dial plate or pointer 8 are fixed on by thimble 9 on the central shaft of passive dial 6, together rotate with passive dial 6.Being fixed with anti-dazzling screen 10 by nut 7 on the central shaft of passive dial 6 also together rotates with passive dial 6.On the optocoupler 11 fixed installation housings, when anti-dazzling screen 10 passes through optocoupler 11 Baltimore grooves, give the zero-bit that principal computer can be determined indicator thereby produce high opening into signal.
