Offer a tie rod hole 620 at the center of piston 600, in the periphery of tie rod hole 620, there is tapered knife
Pedestal positioning ring groove 630.
Cavity between piston 600 and end cap 500 constitutes a hydraulic pressure oil sump 800.Additionally at tool rest 300
Mounting flange 310 in offer oilhole (not shown), the inner of this oilhole and hydraulic pressure oil sump
800 connections, are provided with a pressurizing adaptor 810 with non-return valve function on the outer end of this oilhole.
The cutter hydraulic machinery clamping head be given in figure also has a tapered knife pedestal 700, this tapered knife
Pedestal 700, from the point of view of profile, has one in order to extension and in the flange portion 710 and installed
Outer extension, interior extension is a cylindrical portion 720, and outer extension is head 730.
Flange portion 710 is fixed on the barrel 320 of tool rest 300 by securing member such as bolt 711
On end face and seal.Cylindrical portion 720 extends towards piston 600 direction, and is inserted into the cone of piston 600
In shape tool post positioning ring groove 630.
This tapered knife pedestal 700 has a centre bore 740, and centre bore 740 is divided into three sections, a section
It is pulling claw accommodating hole 741 in tapered knife pedestal 700 inner terminal, one section of taper being positioned at head 730
Handle of a knife hole 743, middle one section is an expanding hole 742, pulling claw accommodating hole 741 and tapered knife delthyrium 743
Connected by expanding hole 742.The internal diameter in expanding hole 742 is more than the internal diameter of pulling claw accommodating hole 741.Should
Tapered knife pedestal 700 is provided with a radial end face 744 at the root of cylindrical portion 720.In cylindrical portion 720
On be cased with a reseting elastic element making piston 600 reset, the two ends of this reseting elastic element respectively with
Radial end face 744 on tapered knife pedestal 700 and piston 600 are towards that of tapered knife pedestal 700
Face 620 contacts.This reseting elastic element is formed by stacking by some butterfly springs 900.
The cutter hydraulic machinery clamping head be given in figure also has a pull bar 910 and a pulling claw 920,
Pulling claw 920 overwhelming majority is positioned at pulling claw accommodating hole 741, and pulling claw accommodating hole 741 is near piston 600
One end be connected with pull bar 910, pulling claw 920 outwardly claw 921 drops into expanding hole 742

Rod aperture 620 is threaded, and is also configured with sealing ring between pull bar 910 and piston 600.At pawl
The inner side in portion 921 is provided with to clamp the clamping part 922 of the blind rivet 1010 on knife bar 1000.
The operation principle of above-mentioned cutter hydraulic machinery clamping head is:
When the oiling joint in mobile tool magazine docks with the pressurizing adaptor 810 with non-return valve function and not
During oiling, the pressurizing adaptor 810 with non-return valve function is open-minded, to the oil pressure in hydraulic pressure oil sump 800
Carrying out pressure release, after the oil pressure in hydraulic pressure oil sump 800 declines, some butterfly springs 700 release energy, drive
Piston 600 moves to facing head 400 direction, and piston 600 drives pull bar 910 to facing head 400
Moving in direction, pull bar 910 pulls pulling claw 920 also to move to facing head 400 direction, pulling claw accommodating hole
741 compressing claw 921 inward collapsibles so that the clamping part 922 inside claw 921 clamps knife bar 1000
On blind rivet 1010 and drive blind rivet 1010 to facing head 400 direction move so that knife bar 1000
On taper handle of a knife 1020 enter into the tapered knife delthyrium 743 of tapered knife pedestal 700 and realize tight fit
And fix knife bar 1000.If desired tool changing, then carry out oiling by the pressurizing cylinder in mobile tool magazine,
By oiling joint and pressurizing adaptor 810 oiling in hydraulic pressure oil sump 800 with non-return valve function,
Oil pressure in hydraulic pressure oil sump 800 raises, and after the resistance overcoming some butterfly springs 700, promotes and lives
Plug 600 moves to principle facing head 400 direction, and piston 600 also drives pull bar 910 to the flat rotation of principle
