When piston be to move upwards, clamping force F=P* π * (D/2)2, relative to the piston of pull-down, clamping force F=P* π * (D2/4-
d2/ 4), in same volume, this structure clamping force is bigger.3, it clamps and uses hydraulic control, clamping force size is controllable, together
When the stability of clamping force can be monitored by monitoring pressure.Guaranteed when release by mechanical spring, more compared to hydraulic unlock
Stablize, mother's pin is forcibly taken away from male pin when avoiding because not unclamping, and is damaged to it.More succinct (the road binders, all the way of pipeline simultaneously
Gas).4, male and female pin unclamp when, have top through-hole and the circular hole of side 6 simultaneously blow, can be effectively ensured to positioning surface progress
Mass flow air cleaning.5, female pin is positioned with exchangeable workbench by straight mouth, can be hit big, position is not easy to change.6, exist
In binding clasp position fixing process, due to female pin center be it is empty, when dropping process starts, allow and one biggish bias of male pin
Amount, (and the binding clasp of blind rivet structure, blind rivet must be by male pin centre bores then without so big eccentricity).Falling to one
When half trip, a coarse positioning, gap 0.2mm can be carried out with the cylindrical side at the top of male pin on the upside of female finger setting face.Such energy
It effectively reduces in dropping process because of the impact and abrasion of positioning surface caused by eccentric.
