Detailed description of the invention
Embodiment, as shown in Figure 1: fast positioning clip clamping unit, comprising: the parts such as body 10, base 20, charged piston 30, upper end cover 40, pulling piston 50, blind rivet 60, top cover 70.Concretely:
This body 10 has upper and lower penetrating inner chamber.This inner chamber is followed successively by the first annular seal space 11, the second annular seal space 12, the 3rd annular seal space 13 from bottom to up.Wherein, the cross-sectional area of this second annular seal space 12 is less than the cross-sectional area of this first annular seal space 11, is also less than the cross-sectional area of the 3rd annular seal space 13.Preferably, the cross-sectional area of this second annular seal space 12 is the half of the cross-sectional area of this first annular seal space 11.
The lower ending opening of these base 20 these the first annular seal spaces 11 of sealing.Such as, this base 20 is fixed on the bottom of this body 10 by attachment screw, and this base 20 is fixed on the workbench of lathe.
This charged piston 30 has the major part piston 31 and the superposed microcephaly's piston 32 that are positioned at bottom.This major part piston 31 is compatible with this first annular seal space 11, this microcephaly's piston 32 is compatible with this second annular seal space 12.That is, what these major part piston 31 sealings were slided is positioned at this first annular seal space 11, and what these microcephaly's piston 32 sealings were slided is positioned at this second annular seal space 12.
The upper end open of this upper end cover 40 sealing the 3rd annular seal spaces 13, and the axial line place of this upper end cover 40 be sealed and matched be provided with steel ball sleeve 41.Certainly, the middle part of this upper end cover 40 is penetrating, and this steel ball sleeve 41 can be connected with this upper end cover 40 by attachment screw.The axial line place of this steel ball sleeve 41 is provided with centre bore 42, and the sidewall of this centre bore 42 is provided with the steel ball 43 of the sidewall that runs through this centre bore 42., this steel ball 43 can inside and outsidely slide.Certainly, the diameter of this steel ball 43 is greater than the thickness of the sidewall of this centre bore 42.
This pulling piston 50 is positioned at the 3rd annular seal space 13 and the 3rd annular seal space 13 matches.Meanwhile, the middle part of this pulling piston 50 is provided with upwardly extending boss 51, and the axial line place of this boss 51 is provided with lower jack 52, and is provided with butterfly spring 53 between this pulling piston 50 and this upper end cover 40.Meanwhile, the steel bead groove 54 that the sidewall of this lower jack 52 is provided with and this steel ball 43 matches., this steel ball 43 can be stuck in this steel bead groove 54 after outwards sliding.
What this blind rivet 60 was sealed and matched runs through this centre bore 42, and the bottom of this blind rivet 60 is injected in this lower jack 52.Certainly, this upper end cover 40 tops are stretched out in the upper end of this blind rivet 60.Meanwhile, the cannelure 61 that the lower sides of this blind rivet 60 is provided with and this steel ball 43 matches.Two limit walls up and down of this cannelure 61 are skewed.That is, the part that this steel ball 43 is positioned at the sidewall of this lower jack 52 is stuck in this cannelure 61, and the sidewall of 2 inclinations can push this steel ball 43 and makes it outside movement.And this steel ball 43 has free gap in this cannelure 61 on above-below direction.
This top cover 70 is between the lower surface of this blind rivet 60 and the bottom of this lower jack 52, and this top cover 70 has up and down gap.This free gap is approximately 3mm left and right.
And the space forming between this base 20 and this charged piston 30 is communicated with compressed air source (not shown on figure) by check valve (not shown on figure).In the space forming between this charged piston 30 and this pulling piston 50, be filled with hydraulic oil.
Optimize, on the upper surface of this upper end cover 40, be distributed with dowel hole 44, and all dowel holes 44 are mal-distribution.So-called mal-distribution refers to any two dowel holes 44 not with the center line symmetry of this upper end cover 40.Such asymmetric design anti inert.
In sum: this base is connected with workbench, this charged piston doubles compressed-air actuated pressure, pass to pulling piston by hydraulic oil, this disk spring is fixed between this pulling piston part and this upper end cover, and this pulling piston can move up and down in the 3rd annular seal space.Move up while withstanding this upper end cover when hydraulic oil promotes this pulling piston, this steel ball can be retracted in the steel bead groove on this pulling piston.Now, this top cover can be by this blind rivet jack-up 1-2mm, thereby user can easily take workpiece away.Under the effect of check valve, this pulling piston remains on this position and changes after new workpiece, bleed off compressed air, this pulling piston moves down under the effect of butterfly spring, after this steel ball moves inward, is pressed on the conical surface of blind rivet, will tightly hold this blind rivet and form self-locking.Certainly, can be using this fast positioning clip clamping unit as special fixture thereby can adjust by adjusting the width of this cannelure the size of clamping force.Meanwhile, this clamping unit is without the complex component such as pipeline and hydraulic fluid tank, thereby comparatively simple, cost is lower.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
