The space stated between blind rivet 8 and convex platform is connected, and the other end stretches in the leakage fluid dram 11.Correspondingly, the piston 2 is gone back
With the lower convex platform extended in the leakage fluid dram 11, the apocenosis passage is extended in the lower convex platform.To internal product
Liquid can be emitted into outside fast positioning clamping device by the apocenosis passage.
The positioning disk 9 is fastened on the centre bore, is on annulus shape and steel ball sleeve 6 with spring steel making outer
Shape is coincide, and inner hole is for positioning, and when the top surface of positioning disk 9 is depressed, inner hole can reduce, so as to eliminate between the cooperation of axis
Gap, remaining deformation will become spring force and then be held in position precision.The upper surface of the upper end cover 4, which offers, to be shifted to install
Location hole 91.Wherein, the purpose of the fool proof when workpiece positioning that the location hole 91 shifted to install is realized, is determined by what is shifted to install
Position hole 91 can realize the coarse positioning of workpiece.In one embodiment, the quantity of the location hole 91 is four, four location holes
Two in 91 shift to install, other two is shifted to install.
Meanwhile the positioning disk 9 can further eliminate the gap of assembly, be advantageously implemented the accurate positioning of workpiece.In addition,
Positioning pin 5 is additionally provided on the upper end cover 4, the positioning pin 5 is symmetrically distributed in the two sides of the blind rivet 8.
The spring 3 is set on the convex platform of the piston 2, and the both ends of the spring 3 and the upper end cover 4 and work
Plug 2 leans.To which the power of the piston 2 derives from compressed air, is also from the elastic acting force of the spring 3.
Preferably, the spring 3 is butterfly spring.
In order to realize the self-locking of blind rivet 8, the fast positioning clamping device further include: steel ball sleeve 6 and steel ball 10.Wherein,
The steel ball sleeve 6 is set on the blind rivet 8, and between the blind rivet 8 and upper end cover 4, the steel ball 10 is embedded in institute
Steel ball sleeve 6 is stated towards on the wall surface of the side of the convex platform inner space.In addition, the blind rivet 8 and convex platform inner space
Side on be provided with 10 slot of steel ball matched with the steel ball 10,10 slot position of steel ball on the side is in the blind rivet 8
On 10 slot of steel ball lower section.
To which the fast positioning clamping device of the utility model is in use, the pedestal 1 is connect with workbench, when piston 2
Lower part enters compressed air, which moves up.At this point, steel ball 10 can be in 10 slot of steel ball on setback side, the top cover
7 can jack up the blind rivet 8, can easily take workpiece away.
After changing new workpiece, compressed air is bled off, which moves down under the action of disk spring 3, the piston
Steel ball 10 can be pushed to center to be pressed in 10 slot of steel ball of the blind rivet 8 by 10 slot of steel ball in 2, then tightly hold blind rivet 8,
Realize the self-locking of blind rivet 8.Furthermore can also by adjusting 10 slot of steel ball of blind rivet 8 width and adjust the size of clamping force.
In conclusion the fast positioning clamping device of the utility model is while providing enough clamping forces, have compared with
Small volume.Meanwhile the fast positioning clamping device of the utility model also has the advantages that facilitate drain and registration.
