The standard electromagnetic brakes are ingeniously utilized and simply combined to realize control on rotation and swing of the comprehensive test rotary table of the gyroscopic instrument, so that quick conversion between swing and rotation test states of the rotary table can be realized.
Description
Technical field
The present invention relates to a kind of clutch and brake mode of gyroscope instrument compbined test turntable and wave and spinning top instrument compbined test turntable.
Background technology
Original gyroscope instrument compbined test turntable is divided into and waves and spinfunction, and gyroscope instrument compbined test turntable operationally rotates and the conversion of waving has the problem of three aspects.One is that toothed clutches its wearing and tearing under long-term work patten transformation can bring the decline of precision; Two is that operationally velocity of rotation is slower due to turntable, error during flute profile occlusion can cause the delay of time, operationally the requirement rotating speed of turntable is generally 0.1 degree/second, but can gap be produced during flute profile engagement, the delay of 5-20 second when will cause conversion, bring great inconvenience to measurement, and easily cause error; Three is that precision owing to engaging flute profile is high, thus part to add technology level requirement in man-hour high, cost and the difficulty of processing of product can be increased, and when assembling, the requirement of technology and environment is high, generally not easily completes.
Summary of the invention
The present invention seeks to invent a kind of a kind of mode of braking of gyroscope instrument compbined test turntable and wave and spinning top instrument compbined test turntable.
The braking method of gyroscope instrument compbined test turntable, it is utilization two groups of electromagnetic brakes, through being combined into electromagnetic clutch, one of them electromagnetic brake controls upper table surface, another one electromagnetic brake controls mair motor, and send by embedded computer the break-make that electric signal controls upper and lower two groups of electromagnetic brakes, make gyroscope instrument compbined test turntable realize rotating and the high precision rapid translating waved.
Use the gyroscope instrument compbined test turntable of described braking method, it has upper and lower two groups of electromagnetic brakes, two groups of electromagnetic brakes are through being combined into electromagnetic clutch, the upper table surface of one of them electromagnetic brake joint test turntable and upper cover control upper table surface, and the mair motor of another one electromagnetic brake control linkage test turntable and the chain-wales be made up of pallet control mair motor.
The present invention adopts an electromagnetic brake to connect mair motor and chain-wales, and another connects upper table surface and upper cover, by working independently of two groups of electromagnetic brakes, realizes the function of waving and rotating.By reasonably designing the connection of detent.1. solve the problem delayed switching time in the past, can ensure that turntable is in quick, the high-precision conversion rotated and under waving.2. solve problem too high to technical requirement in process, save processing cost, shorten erection debug time.3. solve the problem that equipment is easy to wear, extend the serviceable life of equipment.
Error when reducing power and energy by changing detent and other element connected modes extends serviceable life.Just based on this method, be connected with other assemblies by control brake, form the brake system of turntable, will service precision and the serviceable life of equipment be improved, and enable turntable meet the requirement of product test.This technology not only can realize a turntable and possess the basic function of waving and rotating, and turntable is freely changed at work; And gyroscope instrument compbined test turntable can be made to realize waving and rotate under two states quick, accurately change, gyro sort instrument (the directional gyro in aviation can be widely used in, Horizon table), accelerometer, slip indicator, the inertia such as turn meter unit, device and inertia system detect.
The present invention uses two groups of detents cleverly, through being simply combined into electromagnetic clutch, makes gyroscope instrument compbined test turntable can realize rotating and the high precision rapid translating waved.Overcome the time delays that profile of tooth engagement clutch mode causes when the slow-speed of revolution works, gyroscope instrument compbined test turntable can be made to enter into detected state fast.
Accompanying drawing explanation
Figure is this present invention gyroscope instrument compbined test turntable cut-away view.
Figure number illustrates: 1, upper table surface; 2, index dial; 3, upper cover; 4, upper detent; 5, conducting ring; 6, pot; 7, pallet; 8, electric disc; 9, lower conducting ring; 10, mair motor; 11, set collar; 12 times detents; 13, slide block group; 14, push-rod electric machine; 15, slideway frame; 16, coupling shaft; 17, support is waved.
Embodiment
Gyroscope instrument compbined test turntable embodiment of the present invention as shown in the figure.It has the electric disc 8 for fixing mair motor 10, compresses mair motor 10 make it be fixed tightly on electric disc 8 by four long spiro nails with set collar 11.
Gyroscope instrument compbined test turntable mair motor main shaft is connected by key, and mair motor main shaft is direct and pallet is directly fastening, ensures pallet synchronous axial system when machine operation.
Pallet is embedded with a slide block group 13, outside pallet, being fixed with a push-rod electric machine 14 with a pot 6 is connected with outside slide block group 13, under the effect of push-rod electric machine 14, ensure slide block group 13 and pot 6 synchronous slide, the precision that push-rod electric machine is synchronous with slide block here does not affect potentiometric precision.Be embedded with a bearing in slide block and ensure drive axis, be embedded with an oscillating bearing within the bearing, to ensure that rotational plane can meet tilt requirements.
Install detent 12 in coupling shaft 16 and pallet 7 joint, during energising, the attracting rotatable platform that realizes of lower detent 12 rotates with mair motor; Rotary motion is uploaded to upper table surface by coupling shaft by rotatable platform, and whole like this turntable just realizes planar rotational movement.When instantly braking 12 device power-off, upper detent 4 is energized, lower detent is separated, and provides order, combine with push-rod electric machine 14 and pot 6 by embedded computer, realize upper table surface 1 to tilt in the optional position at 0-10 degree angle, at this moment mair motor drives rotatable platform to rotate, and upper table surface 1 drives upper table surface 1 oscillating motion by the coupling shaft 16 tilted, because upper detent 4 is energized, index dial 2 maintains static, upper table surface 1 makes upper table surface to rotate under the effect of swaying base 17, realizes waving.
Be equipped with detent 4 above coupling shaft and between upper cover 3, in this product, two detents only allow a brake operation.During detent power-off instantly, upper brake guaranties, can realize rotatable platform and housing fixes, and under the effect of pallet and swaying base, realizes waving of rotatable platform.Instantly brake guaranties, during upper detent power-off, can realize the rotation of rotatable platform.
