Floating taper positioning sleeve, which floats, is displaced maximum.
Preferably, the floating taper positioning sleeve includes being integrally formed and having to match centre bore with the screw mechanism
Taper sheath top and cylinder lower part, wherein the taper sheath top extends outwardly and forms the edge of a wing, the edge of a wing and clamp seat it
Between the elastic component is set, the cylinder lower part and the inner hole glade plane space that clamps cooperate.
It is furthermore preferred that cylinder lower part is less than 0.01mm with the fit clearance for clamping an inner hole.
Preferably, the elastic component is below floating taper sheath and to clamp the pressure between seat with circumference equidistantly distributed
Contracting spring.
It is furthermore preferred that there are four the compressed spring sets.
Preferably, the standard round that cooperation is docked with vertical surrounding processing center machine tool is processed into the lower part for clamping seat
Cylindricality.
Preferably, it is described clamp to be additionally provided on seat protrude its surface and the diamond shape with the parts to be processed position matching
Step positioning pin.
Preferably, the gasket is opening gasket.
Compared with the prior art, the present invention has following improvement:
(1) 7 processes can be merged into a process by vertical (four axis) machining center clamp in the present invention only needs one
Secondary clamping is just capable of processing molding, and process is simple and convenient, labour's intensity is small, turnover process is short, high production efficiency；(2) it uses
The circular conical surface of floating taper positioning sleeve is in contact positioning with parts to be processed orifice chamfer face；(3) diamond shape step pin, constraint are used
The rotary freedom of parts to be processed；(4) clamping module lower half portion is standard cylindrical, can be with the scroll chuck of four axis lathes
Easily docking is fixed；(5) clamping all components in module is alloy steel plus reasonable heat treatment process, service life
It is longer；(6) hatch frame is arranged in the gasket in clamping component, only need to first unclamp pinching screw during changing the outfit part, presss from both sides
Tight screw, which does not have to back-out completely, to be come, and removes gasket, it can be achieved that Quick universal.
Compared with prior art, the invention has the following advantages that
(1) high in machining efficiency: the yield of traditional processing mode per tour is 20, qualification rate 86.4%, vertical (four axis)
Machining center clamp, the yield of per tour are 180, qualification rate 97.8%.
