Abstract
A macro and micro double-stage final motion adjusting device based on a harmonic reducer relates to the technical filed of displacement precision adjustment, and aims to solve the problems that most of existing displacement platforms achieving macro and micro double-stage final motion adjusting achieve precision displacement adjustment through the combination of two one-dimensional displacement adjusting devices, so that the displacement platforms are increased in volume, small in bearing capacity, relatively strict in application environment, and difficult to be applied to the occasions which are strict in requirement for space and size, large in bearing capacity and poor in application condition. An outer circle surface on the left side of an adjusting knob is embedded in an inner sleeve, and a lock screw is arranged at the right end of a shell. An output end of a low speed shaft of a harmonic gear reducer is arranged on the left side of the adjusting knob, and an input end of a high speed shaft of the harmonic gear reducer is arranged on the right side of the adjusting knob. The macro and micro double-stage final motion adjusting of the macro and micro double-stage final motion adjusting device based on the harmonic reducer is arranged on the same axial line, so that the problems of complex structure, large size and high manufacturing cost which are caused by a common macro and micro double-stage final motion adjusting device is solved.

At present, micro-displacement apparatus commonly used mainly contains following several:
1) motor+lead screw guide rails is secondary: traditional mechanical transmission-type micro-displacement apparatus, use also comparatively extensive the earliest.Its frame mode is mainly that to adopt motor be driving element, with leading screw as web member, with rail plate as support platform.The precision of this structure shift device directly is subject to electronic self constraint, because of the magnetic pole of motor can't do less, limited the raising of bearing accuracy.
2) based on the micro-displacement apparatus/voice coil motor of linear electric motors+piezoelectric ceramics: this is that a kind of linear electric motors and piezoelectric ceramics of utilizing is as the micro-displacement apparatus of actuation element.Compare with traditional lead screw guide rails micro-displacement apparatus, this micro-displacement apparatus has higher displacement accuracy, has simultaneously the advantages such as response speed is high, low in energy consumption, thereby is paid close attention to widely and use.The grand motion of the device of the type is adopted linear electric motors to drive guide rail and is realized feeding, and micromotion drives flexible hinge by piezoelectric ceramics or voice coil motor is realized feeding.But due to the restriction of its flexible hinge version, this micro-displacement apparatus working range is limited, usually at several microns in tens micrometer ranges, and tangentially without load-bearing capacity, applied environment is stricter.
So far, the overwhelming majority realizes that the displacement platform of grand little two-stage displacement accurate adjustment is all to combine by two one dimension displacement adjusting gears to realize the precise displacement adjustment, increased the volume of displacement platform and load-bearing capacity is little, applied environment is stricter greatly like this, be difficult to be applied in strict to bulk, bearing capacity is large, application conditions is poor, and requires the occasion realize that fast high-resolution displacement is adjusted.
Summary of the invention
The purpose of this invention is to provide a kind of grand little two-stage micro-positioning regulators device based on harmonic speed reducer, realize that in order to solve existing great majority the displacement platform of grand little two-stage displacement accurate adjustment is all to combine by two one dimension displacement adjusting gears to realize the precise displacement adjustment, and existence has increased the volume of displacement platform and load-bearing capacity is little, applied environment is stricter, is difficult to be applied in the occasion strict to bulk, that bearing capacity is large, application conditions is poor.
Described purpose realizes by following scheme: described a kind of grand little two-stage micro-positioning regulators device based on harmonic speed reducer is comprised of housing, lock-screw, harmonic gear reducer, bearing, adjustment knob, vernier adjustment knob;
Described housing is drum type, is inlaid with bearing on the inner headed face on the left of housing; Described adjustment knob is drum type, the periphery in adjustment knob left side is embedded in the inner sleeve of bearing, the right-hand member of housing is provided with lock-screw, the inner headed face gap on the periphery of adjusting the knob right side and housing right side is relative, make lock-screw and the periphery phase apical grafting of adjusting the knob right side after the downward precession of lock-screw, make and adjust knob and can not relatively rotate with housing, not when adjusting the periphery phase apical grafting on knob right side, the adjustment knob can relatively rotate with housing at lock-screw; It is inboard that harmonic gear reducer is arranged on the adjustment knob, and the shell of harmonic gear reducer is connected with the inner headed face of adjusting knob, the slow-speed shaft output terminal of harmonic gear reducer is arranged on the left side of adjusting knob, the high speed shaft input end of harmonic gear reducer is arranged on the right side of adjusting knob, is connected with vernier adjustment knob on the high speed shaft input end of harmonic gear reducer.
The present invention has the following advantages: grand little two-stage adjustment of displacement of the present invention is positioned at same axis, solved the problem that complex structure, volume are large, manufacturing cost is high that common grand little two-stage displacement adjusting device brings, install simple and conveniently, and the present invention has realized big speed ratio, fast offset adjustment.Work as employing
Harmonic DriveThe high precision harmonic gear reducer, the ratio of gear of high precision harmonic gear reducer is: during 100:1, grand inching is than being 100:1.And have advantages of simple in structure, volume is little, easy maintenance cost is cheap.
