Description
Technical field
The utility model belongs to the surveying instrument field, especially the big machinery force measuring machine.
Background technology
As everyone knows, the large-scale high-precision force measuring machine uses high precision standard test weight (each 1t) usually, when weighing reaches tens of ton hours, because of the volume of counterweight is big, requires high to use equipment and environmental baseline.This class force measuring machine is bulky, highly reaches a few floor height, and weight reaches tens tons even more than 100 ton, involves great expense.
A kind of common comparison formula force measuring machine is arranged, after the hydraulically operated equipment (HOE) pressurization, measure as standard by single high-precision weighing sensor.Because inevitably to be subjected to the significant impact of hydraulic power source motor oscillating, hydraulic pressure fluctuation and hydraulic leak, and the restriction of single LOAD CELLS error, this type of force measuring machine precision is lower.Simultaneously because of the maximum distortion of LOAD CELLS own only about 0.3mm, have any problem with the mode control survey precision of mechanical-force-transmission screw press.Demarcate because the limitation of this mechanism principle, this force measuring machine can only be carried out force measuring machine as standard by single high-precision weighing sensor, and can not define the accuracy class of force measuring machine with directly demarcating with the high precision standard test weight.
Have one with reference to patent, can be used as high precision does not have hydropress tool force measuring machine:
ZL99 2 59068.0, a kind of LOAD CELLS appliance special for detecting: the LOAD CELLS appliance special for detecting is made up of body, frame, LOAD CELLS, actuating unit pressing mechanism and operation instrument.Between frame and bearing platform table top, the compression displacement of being made up of some springs increases a times mechanism; The actuating unit of forming by controllable motor and cycloidal-pin wheel speed reduction unit, when the pressing mechanism that drive is made up of screw rod and nut pressurizes automatically, the spring that compression displacement increases in times mechanism shrinks under pressure, and the frame displacement is big than the tens of multiplications of sensor distortion itself, thereby carries out pressure control easily.Simultaneously, between the base of body and bearing platform, form sensor groups, can significantly improve measuring accuracy with some LOAD CELLS.
Find in the practice, when the actuating unit of being made up of controllable motor and cycloidal-pin wheel speed reduction unit directly drives the pressing mechanism of being made up of screw rod and nut and pressurizes automatically, this mechanism's complexity and very big; At this moment the cycloidal-pin wheel speed reduction unit is run counter to design general knowledge and is squeezed installation, and the not smooth equipment of lubricant passage way damages easily; The actuating unit that controllable motor and cycloidal-pin wheel speed reduction unit are formed is placed in the underground dell, and installation, maintenance is extremely inconvenient; Because weighing is very big, volume was very huge when the compression displacement of being made up of some springs that above-mentioned patent adopts increased in times mechanism the common stage clip of use.When frame and complete machine become one, pretty troublesome in cubing timing signal dismounting frame; In detecting cargo handling process manual adjustment up and down between jig position dimension labour intensity very big.
Summary of the invention
For being squeezed to install easily, damages by cycloidal-pin wheel speed reduction unit in the dynameter that overcomes above-mentioned ZL99 2 59068.0, significant deficiency such as actuating unit installation, maintenance inconvenience, and the invention provides a kind of high precision does not have hydropress tool force measuring machine.The actuating unit that the stepper motor of this force measuring machine and cycloidal-pin wheel speed reduction unit are formed is placed on the support top of body outside, and the cycloidal-pin wheel speed reduction unit is by design general knowledge normal mounting, and the unimpeded equipment of lubricant passage way is not fragile; The equipment installation, maintenance is extremely convenient.Use whole fast-assembling frame can make the staking-out work of force measuring machine rapider.Motorized adjustment jig position mechanism is installed on housiung separator, has been alleviated working strength of workers.
The technical scheme that its technical matters that solves the utility model adopts is:
High precision does not have hydropress tool force measuring machine, mainly by body, frame, LOAD CELLS group, actuating unit, pressing mechanism, compression displacement increase times mechanism and the operation instrument form; Body is made up of base and bearing platform, and the LOAD CELLS group is placed between base and the bearing platform; Base and bearing platform are controlled the bearing platform horizontal shift with spacing sheet steel; Between four column frames and bearing platform table top, the compression displacement of being made up of the disk spring group increases a times mechanism; Actuating unit is made of stepper motor and cycloidal-pin wheel speed reduction unit and is fixed on above the body base; Pressing mechanism is made up of pressurization screw rod and nut, and is subjected to force direction with the force transferring lever change; The disk spring that increases in times mechanism in the displacement of pressure lower compression shrinks, and makes the displacement of fast-assembling frame big than the tens of multiplications of sensor distortion itself, helps measuring accuracy is carried out accurate automatic indexing, has also dwindled compression displacement and has increased a times mechanism.
Motorized adjustment jig position mechanism is installed: comprise adjustment screw rod, handle, go up anchor clamps on housiung separator, automatically control by controllable motor drive speed reducer structure according to testee adjusted size relevant position, and can make electronic crane scale do 360 ° of revolutions around the appliance special for detecting axle center by the electronic crane scale detection rules of country's promulgation.Above all parts of bearing platform table top comprise that four column frames, compression displacement increase times mechanism and motorized adjustment jig position mechanism is formed whole fast-assembling frame.With being placed on above the bearing platform with the high precision standard test weight after the whole fast-assembling frame dismounting this machine is directly demarcated.
Good effect of the present utility model is:
After pressing mechanism used the force transferring lever change to be subjected to force direction, the cycloidal-pin wheel speed reduction unit met design general knowledge normal mounting, and the unimpeded equipment of lubricant passage way is not fragile; The actuating unit that controllable motor and cycloidal-pin wheel speed reduction unit are formed is placed on the body outside, and installation, maintenance is convenient; Make the output torque of required cycloidal-pin wheel speed reduction unit and reduction gear ratio only for intrinsic 1/5 simultaneously in the installation of force transferring lever, stepper motor of selecting for use and cycloidal-pin wheel speed reduction unit volume-diminished are 2/5 of former patent; The installation of force transferring lever has also reduced the required ratio of compression of mechanism's stroke, and 1/16 the when compression displacement of using disk spring to form this moment increases times mechanism and makes this volume be kept to the common stage clip of former use carries out accurate automatic indexing number to measuring accuracy and can reach 6.4 * 10
5
Base and bearing platform can further improve mechanism stability with the displacement of spacing sheet steel controlling level; Motorized adjustment jig position mechanism is installed, can be improved the automatization level of force measuring machine; Use whole fast-assembling frame that demarcation force measuring machine required time is shortened greatly, also improved the bearing accuracy when repeating frame is installed.This force measuring machine can directly be demarcated with the high precision standard test weight, and the precision that more traditional force measuring machine is demarcated with high-precision sensor significantly improves.
The utility model reduces the volume and weight of force measuring machine significantly, has improved the precision of force measuring machine, has reduced cost.
