Abstract
Damper is loaded the present invention relates to a kind of slight torque calibrating weight, scale pan with a placement counterweight, one suspension hook, the scale pan two ends are connected with suspension hook, the scale pan lower end connects aluminium sheet, and aluminium sheet bottom is suspended between two damping sheets, and described two damping sheet middle lower portions are adsorbed with magnet steel, so that the aluminium sheet 14 produces opposite eddy current magnetism, reducing mechanism concussion.The counterweight is placed on the scale pan upper end.Described two damping sheets are fixed on mounting bracket.The slight torque calibrating weight loading damper of the present invention uses noncontact（Hysteresis damper）Method reduce because place counterweight produce concussion, make the fast quick-recovery stable state of system.
Description
Technical field
The present invention relates to a kind of small torque calibration device, particularly a kind of slight torque calibrating weight loading damper.
Background technology
In small torque calibration device, when placing counterweight mechanism can be made to produce concussion, influence the stability of mechanism, enter
And the precision of whole system is influenceed, and the fast quick-recovery stable state of mechanism after counterweight is placed to enable, the concussion of reducing mechanism, because
This is, it is necessary to which a kind of principle of use hysteresis damper applies the slight torque calibrating weight in counterweight load maintainer to load damping
Device.
The content of the invention
Hindered it is an object of the invention to the defect existed for prior art there is provided a kind of loading of slight torque calibrating weight
Buddhist nun's device, reduces the concussion of the mechanism because caused by placing counterweight so that system can fast quick-recovery stable state.
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that：
A kind of slight torque calibrating weight loads damper, and the scale pan with a placement counterweight a, suspension hook is described
Scale pan two ends are connected with suspension hook, and the scale pan lower end connects aluminium sheet, and aluminium sheet bottom is suspended between two damping sheets, described
Two damping sheet middle lower portions are adsorbed with magnet steel so that the aluminium sheet 14 produces opposite eddy current magnetism, reducing mechanism concussion.
The counterweight is placed on the scale pan upper end.Described two damping sheets are fixed on mounting bracket.
Compared with prior art, the present invention has the advantages that：
The slight torque calibrating weight loading damper of the present invention uses noncontact（Hysteresis damper）Method reduce because putting
The concussion of counterweight generation is put, makes the fast quick-recovery stable state of system.
Brief description of the drawings
Fig. 1 loads the dimensional structure diagram of damper for the slight torque calibration of the present invention；
Fig. 2 loads the front view of damper for the slight torque calibration of the present invention.
Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
Referring to Fig. 1 ~ Fig. 2, this slight torque calibrating weight loading damper, including suspension hook 10, scale pan 12, counterweight 11,
Aluminium sheet 14, damping sheet 15, magnet steel 16, mounting bracket 13；The counterweight 11 is placed on the upper end of scale pan 12, the scale pan 12
Two ends are connected with suspension hook 10, and lower end is connected with aluminium sheet 14；The magnet steel 16 is adsorbed in the middle of described two damping sheets 15, the resistance
Buddhist nun's plate 15 is fixed by screws on mounting bracket 13.
Referring to Fig. 1 ~ Fig. 2, the aluminium sheet 14 is connected by screw in the lower end of scale pan 12, through the mounting bracket 13
It is suspended between two damping sheets 15.
When counterweight 11 is placed on the scale pan 12, the suspension hook 10, scale pan 12, counterweight 11 will produce shake
Swing, installed in the lower end of scale pan 12 aluminium sheet 14 will swing, because the magnetic field 17 that magnet steel 16 and damping sheet 15 are produced makes
The aluminium sheet 14 produces opposite eddy current magnetism, the power of generation is with the swaying direction of aluminium sheet 14 on the contrary, and then realizing reducing mechanism
The function of concussion.
The slight torque calibrating weight loading damper of the present invention, it is necessary to carry out counterweight in slight torque calibration process
Loading, scale pan and its accessory system produce vibration so that calibration data reading is difficult, and counterweight value is very during due to loading
It is small, usually g or mg grades of loading, it is therefore desirable to which scale pan is rapid static and stably, after the hysteresis damper mechanism, reading
More stablize, time of measuring can be reduced, improve accuracy of measurement.The design has simple in construction, ingenious in design, stability good
Advantage.
