Reason is abundant, after time processing shaping, its position error very little, and its amendment position error is more convenient.
Adjusting screw by two position errors of adjustment can correct position error, it is also possible to file amendment elasticity
Pillar body reaches the purpose for correcting position error with file amendment aluminum reed.
Another of the present invention it is critical that using the strong magnetic of ultra low temperature coefficient as permanent magnet,
And the lever amplification ratio of elastomer is increased, make the volume and weight of magnet steel preposition not as good as architomia
Formula weighs a quarter for passing big device.
Another of the present invention is it is critical that adopt in built-in optical electric position governor motion.It is built-in
Photoelectricity governor motion includes a photoelectricity frame that can be positioned in soft magnetic bodies magnet steel cap, thereon equipped with double
Silicon photocell and electroluminescent lamp.The upper-lower position of photoelectricity frame can up and down be adjusted by four set screws,
To adjust the balance point position of sensor.
The present invention another it is critical that photoelectricity governor motion, solenoid, permanent magnet,
Soft magnetic bodies magnet steel, the combination of soft magnetic bodies magnet steel cap are 40mm in a diameter, the cylinder of height 35mm it
It is interior, and this cylinder is inlaid in completely within integrated elastic body.So make the whole of sensor
Body, aesthetic property are greatly reinforced.
Another of the present invention is it is critical that the spacing groove by soft magnetic bodies magnet steel of overload and magnet steel hat
Into a square shaped gap lever is carried out up and down it is spacing, and overshoot protection catch coordinates Zhi Chong
Shell fragment can prevent excessive impact from causing damage to sensor.During normal weighing, lever is to touch
To the spacing place of magnet steel.When overloading or being impacted, lever can encounter spacing place, make elastomer
Deformation no longer increase, so as to protect elastomer.And in fact, the elastomer of this kind of structure, even if
Lever is not carried out it is spacing, when weight a shell fragment encounter overshoot protection catch when, elastomer also exists completely
Elasticity can be recovered completely in region.All these measures, can greatly prevent sensor because transport or
Improper use is damaged.
Another of the present invention is it is critical that as a result of larger lever amplification multiple and magnetic
Higher permanent magnet so that the driving current needed for solenoid is greatly reduced so that match therewith
The lower power consumption of control panel of electronic balance, caloric value reduces.This not only lowers the unit of control panel
Device purchase cost, reduces the area of control panel, and temperature rise when can reduce the work of whole machine,
Reduce the temperature drift of electronic balance.
Another of the present invention is it is critical that integrated elastic body is for the requirement of processing mechanical apparatus
It is not high.If screw thread is machined by tapping, the minimum requirements of processing equipment is only that a band is moved certainly
The high accuracy milling machine machining center of 2.5 axles of knife function (tool magazine capacity at least only needs seven) and one
Non- linkage high accuracy right angle turntable.If using completely 3 axle machines and bigger tool magazine capacity, can
Screw thread also time processing shaping, and profile fineness can be made it is very beautiful.In the minimum of machinery
Under configuration, still integrated elastic body clamped one time can be shaped, considerably reduce human error,
So that product can carry out large-scale production, labor productivity is drastically increased, and make product
Uniformity be greatly enhanced.
Implement the weighing sensor suitable for electronic balance of the present invention, have the advantages that：It is whole
Body is strong, and rugged construction, sensor is hardly damaged in transport and assembling process, and good looking appearance,
Weighing sensory field such that it is able to be able in electronic balance is widely used.
