Description
Technical field
The present invention relates to a kind of force transducer verification system, relate in particular to a kind of superposition type wide region power that is used for force standard machines and load and measurement mechanism.
Background technology
At present, to the verification system of force transducer mainly be to adopt force standard machines to carry out, force standard machines can be divided into dead weight formula, lever, fluid pressure type and superposing type etc. by structure.Dead Weigh Force Standard Machine is that the masterpiece that produces with counterweight is a scale load; The lever force standard machines be the power that produces with counterweight after lever amplifies as scale load; Hydraulic Standard Force Meter be the power that produces with counterweight after hydraulic system is amplified as scale load; Superposing type force standard machine is that the masterpiece that produces with hydraulic pressure or mechanical system is a scale load, is added on the checking matter through drawing or press charger by predefined value.
Dead weight formula, lever and fluid pressure type formula force standard machines basically all directly or indirectly produce power through counterweight, and that the progression of counterweight can distribute is very thin, so the range ability of this type of force standard machines is than broad, but have the low shortcoming of degree of accuracy.Though superposing type force standard machine have easily can operate, cheap price, degree of accuracy advantages of higher; But when work, depend critically upon the standard transducer of its use; And the lower limit of standard transducer uses generally about 15%, has so just restricted the range ability of superposing type force standard machine, can only the special plane special use; The waste resource, and improved user's operation cost.
Summary of the invention
The present invention is intended to the deficiency to prior art, provides a kind of superposition type wide region power to load and measurement mechanism, and it can effectively expand the range of superposing type force standard machine, realizes making full use of of resource, reduces user's operation cost.
For reaching the foregoing invention purpose, the present invention has adopted following technical scheme:
A kind of superposition type wide region power loads and measurement mechanism, comprises oil cylinder, intermediate piston; Inner carrier, intermediate piston force transducer, inner carrier force transducer; Intermediate piston connects bearing plate, and inner carrier connects bearing plate, and intermediate piston can come and go vertically in oil cylinder and move; Inner carrier can come and go vertically in intermediate piston and move, and the intermediate piston force transducer is installed on the intermediate piston, and intermediate piston connects bearing plate and the intermediate piston force transducer links; The inner carrier force transducer is installed on the inner carrier, and inner carrier connects bearing plate and the inner carrier force transducer links, and inner carrier connects bearing plate and is pressed on the intermediate piston connection bearing plate.
Preferably, said intermediate piston force transducer is generally the standard transducer more than three, on the intermediate piston end face, is uniformly distributed with installation, height such as contact point.
Preferably, said inner carrier force transducer is generally an above standard transducer, installs in inner carrier end face centre.
Preferably, the oil-feed of said inner carrier is to enter in the oil pocket of inner carrier through the oilhole on the intermediate piston after entering in the oil groove on the oil cylinder inner wall by the oilhole on the oil cylinder again.
This superposition type wide region power loading and measurement mechanism are in use; Especially when a small amount of journey; Drive inner carrier by inner carrier and inner carrier force transducer and connect bearing plate work, because the inner carrier area is generally 1/3 of intermediate piston area, the range of inner carrier force transducer is generally 1/3 of equipment full scale; The equipment that guaranteed the like this 1/3*15% (be full scale 5%) of full scale that can effectively work, thus the lower limit of equipment significantly expanded.
Have prior art to compare, the present invention has following advantage at least: apparatus structure is simple, easy operating, and highly versatile is suitable for various testing machines and uses.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the present invention, and each assembly and Reference numeral thereof are respectively among the figure: 1-oil cylinder, 2-intermediate piston; The 3-inner carrier, 4-intermediate piston force transducer, 5-inner carrier force transducer; The 6-intermediate piston connects bearing plate, and the 7-inner carrier connects bearing plate.
Embodiment
Understand the present invention for those skilled in the art can more be known, and can implement, technical scheme of the present invention is further explained below in conjunction with a preferred embodiment and accompanying drawing according to the content of instructions.
Consult Fig. 1; This superposition type wide region power loads and measurement mechanism comprises that oil cylinder 1, intermediate piston 2, inner carrier 3, intermediate piston force transducer 4, inner carrier force transducer 5, intermediate piston connect bearing plate 6 and inner carrier connects bearing plate 7; Intermediate piston can move up and down in oil cylinder, and inner carrier is in intermediate piston; Can in intermediate piston, move up and down; The intermediate piston force transducer is installed on the intermediate piston, and intermediate piston connects bearing plate and the intermediate piston force transducer links, and the inner carrier force transducer is installed on the inner carrier; Inner carrier connects bearing plate and the inner carrier force transducer links, and inner carrier connects bearing plate on intermediate piston connects bearing plate.
The intermediate piston force transducer is generally the standard transducer more than three, on the intermediate piston end face, is uniformly distributed with installation, height such as contact point.
The piston force sensor is generally more than one standard transducer, installs in inner carrier end face centre.
Intermediate piston connects the bearing plate center and has the hole, and the diameter in hole is greater than the diameter of inner carrier, and inner carrier can pass intermediate piston connection bearing plate and do rising or decline to-and-fro movement.
Intermediate piston connects bearing plate and inner carrier connection bearing plate is superimposed; Inner carrier connects bearing plate on intermediate piston connects bearing plate; When inner carrier connects bearing plate work; Intermediate piston connects bearing plate does not work, and when intermediate piston connected bearing plate work, inner carrier connected that bearing plate is passive works together.The oil-feed of inner carrier is to enter in the oil pocket of inner carrier through the oilhole on the intermediate piston after entering in the oil groove on the oil cylinder inner wall by the oilhole on the oil cylinder again.
