Abstract

The utility model relates to a high-precision force loading device, which comprises a force application portion and a force sensor (1), and is characterized in that the force application portion includes a rapid oil charging device (4) and a microscale oil charging device (5), the rapid oil charging device (4) stops working when a loading force value of the force sensor (1) approaches to a preset loading force value, and then the microscale oil charging device (5) is started to perform microscale loading for the force sensor (1), so that loading for the force sensor (1) can be realized. Besides, high-precision loading for the force sensor (1) can be realized by the aid of precision microscale loading. The loading device is simple in structure and easy in control, and can improve loading efficiency and calibration precision by means of combination of a rapid loading device and a precision loading device.

Description

The charger of high-precision force
Technical field
The utility model relates to the charger of high-precision force, particularly relates to the charger that is used for high precision high-precision force that force transducer is demarcated.
Background technology
Calibration force cell usual way is to utilize standard test weight directly to lie on the force transducer (as pressure transducer), the longitudinal pressure that the sensor senses counterweight is subjected to, produce pressure signal and output to signal conditioner, by the measured value of data acquisition unit or tensimeter output, calculate the calibration error thus corresponding to the sensor of standard brick sign indicating number.This kind method principle is simple, and is feasible.But limited and discontinuous owing to the number of standard test weight with the power value of counterweight, so can only demarcate and can not demarcate to limited discrete power value to power value continuous in the range ability.And will add by hand and subtract counterweight, inconvenient operation wastes time and energy.Another kind method is to utilize the rocker-type dynamometer to demarcate, utilize the rocking bar on hand a kind of physical construction to apply power, this method is required great effort equally, hand is shaken easily in applying the process of power, make the power value instability that applies, it is bigger to fluctuate, and causes force transducer calibration error to increase, and it can not satisfy standard and the requirement that must be compared by the school sensor in the measurement and calibration process under stable identical conditions.If the power of calibration is very big, just becomes more difficult by the manual application of force of people and even may not.In addition, more than two kinds of methods all need hand computation calibration result, thereby do not have robotization.
Summary of the invention
The purpose of this utility model provides the charger of loading efficiency height, stated accuracy height, simple in structure, the high precision high-precision force that is easy to control.
For solving the problems of the technologies described above, the utility model is taked following technical scheme: the charger of high-precision force, comprise force part and force transducer, and it is characterized in that: described force part comprises quick recharging oil device and micro-recharging oil device; Described quick recharging oil device quits work during near predetermined loading force value in the loading force value of force transducer, then starts described micro-recharging oil device the trace that described force transducer carries out is loaded, thereby realize loading to described force transducer.
Preferably, described force part also comprises pressue device, and described pressue device comprises push rod (2) and large tank (3).
Preferably, the charger of described high-precision force also comprises oil inlet pipe and scavenge pipe, described quick recharging oil device (4) is connected with described large tank (3) with scavenge pipe by described oil inlet pipe with described micro-recharging oil device (5), and described force transducer is added on the described push rod 2.
Described charger is simple in structure, be easy to control, and can improve loading efficiency and stated accuracy by the mode that described quick charger and precision charger combine.
Description of drawings
Fig. 1 is the structural representation of the charger of high precision high-precision force.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated.
As shown in Figure 1, wherein 1 is force transducer, and 2 is push rod, and 3 is large tank, and 4 is quick recharging oil device, and 5 is micro-recharging oil device.
Fig. 1 shows the structural representation of the device in the utility model, and as shown in Figure 1, described charger is made of force part and force transducer 1.
Described force part comprises pressue device, quick recharging oil device 4 and micro-recharging oil device 5; Described pressue device comprises push rod 2 and large tank 3, when described quick recharging oil device 4 and/or micro-recharging oil device 5 in described large tank 3 during oiling, described large tank 3 drives described push rod 2 and loads test pressure to described force transducer 1.
Described quick recharging oil device 4 is connected with described large tank 3 with scavenge pipe by oil inlet pipe with micro-recharging oil device 5, and unidirectional reverse checkvalve is installed respectively on described oil inlet pipe and scavenge pipe, guarantees to add the one-way of unloading and the leakproofness of liquid.
Described quick charger comprises slippage pump 4 and oil feeding reservoir 5; When loading, force transducer is added on the push rod 2, slippage pump 4 by oil inlet pipe to large tank 3 oilings, thereby make described push rod 2 beginning fast rise, in that the loading force value of force transducer is very approaching when needing the loading force value, slippage pump 4 quits work.
When loading, force transducer is added on the push rod 2.To large tank 3 oilings, push rod 2 begins fast rise to recharging oil device 4 by oil pipe fast, and when the very approaching need of the loading force value of force transducer loading force value, recharging oil device 4 quits work fast.Trace recharging oil device 5 begins by oil pipe to large tank 3 oilings, drives push rod 2 and carries out microfeed, and by controlling the repairing speed of micro-recharging oil device, therefore size that can control loaded power value can carry out the loading of high-precision power to sensor.
