The contact area of fingertip is little, so the pressure value passing to pressure transducer 3 will not be disperseed, pressure transducer 3 is by the pressure collecting
Power is transmitted to disconnecting switch pressure tester, carries out showing, analyzes.If the switch of measured high current, its fingertip number
Increase, fingertip spacing increases relatively, the moment of torsion in upset for the clamping force measuring device will be increased, that is, increased operating physical force, in order to
It is easy to clamping force measuring device and can conveniently insert measurement in fingertip, clamping force measuring device passes through scissors lifting mechanism, struts phase
To fingertip, then clamping force measuring device is stretched in fingertip, makes relatively fingertip just press against two arch surface, improve measurement efficiency,
Precision.
What small current, sensing finger pressure were little proceeds to formula switch, can be directly by measurement apparatus attended operation bar 20, by action bars
20 carry out upset simulation contact, and it is more convenient that measurement is got up.
The semicircular arc face of stripper plate 2 is provided with four bent plate installing holes 12(Referring to Fig. 2), bent plate installing hole 12 is screw thread
Hole is used for mounting angle plate 23, by installing bent plate 23, can measure the U-shaped static contact that spacing is 100mm or 160mm spacing.Lead
Four bent plate installing holes 16 are also provided with pressing plate(Referring to Fig. 3), four bent plate installing holes 16 are used for mounting angle plate 23 for screwed hole.
In measurement, pivot pin 4 passes through the pin hole 11 on pin hole 14 and stripper plate on pressure guide plate, by pressure transducer
3 are fixed in sensor mounting hole 10, and the roughness grade number between pin hole and pivot pin is high, are beneficial to and avoid measurement apparatus surveying
Stress during amount, and then make pivot pin 4 produce larger frictional force with pin hole, lead to pivot pin alternative sensor to bear a part
Power.Shown in Fig. 1, when being not added with adnexa, the measurement range of clamping force measuring device is 40mm~50mm, is switched according to different manufacturers
Contact size, can by adjusting screw 5 adjust the distance between stripper plate and pressure guide plate size.
The present invention is based on different adnexa additional in the structure of stripper plate and pressure guide plate(As bent plate, regulation pipe, pad
Block, action bars etc.), realize the disconnecting switch clamping force size of measurement different model, enable existing disconnecting switch industry and own
Clamp type, the measurement of scissor, convertible switch clamping force.
