By ring-shaped cylinder cover, annular piston, the outer cylinder component of circular cylinder composition, 2 sealing rings the 4th and a Yx RunddichtringO are housed in the groove of the inside and outside circle of annular piston respectively, 2 sealing rings the 3rd are housed in the groove of the seam inside and outside circle of ring-shaped cylinder cover bottom respectively, in " U " groove of circular cylinder, circular end face has 4 piston holes, 4 piston rods are loaded in this hole, the upper surface of piston rod contacts with the lower surface of annular piston, the lower surface of piston rod contacts with the upper surface of annular gland, and with the screw threads for fastening of piston-rod lower end together, when pressure oil is from the upper oil cavitie of oilhole outer ring oil cylinder, annular piston is descending, promote piston rod, four fork-shaped tension covers, axle the 3rd is descending, butterfly spring sub-assembly compresses, clamping force between locking plate in holder and swiveling head assembly is cancelled, now servomotor rotates, drive worm screw rotation on one side, while carry out indexing operation around the axis rotation of worm gear, after calibration terminates, the hydraulic oil off-load of outer ring oil cylinder, the resilience of butterfly spring group, ring-like pushing is coiled, piston rod, annular piston resets, again holder 901 and the locking plate in swiveling head assembly are clamped simultaneously.
4. the high accuracy pentahedron milling head of a kind of arbitrary indexing according to claim 1, it is characterized in that: described weight relief arrangement comprises together with ring-shaped cylinder cover is fixed by screws in revolving body, the step of circular cylinder endoporus is equipped with thrust bearing, locking nut matches with the screw thread on ring-shaped cylinder cover top, in order to adjustment and locking thrust bearing; The weight of all parts that revolving body is installed all is delivered on the step in circular cylinder endoporus by thrust bearing, so by circular cylinder by weight transmitting on holder; And the gap between holder and locking plate can be undertaken adjusting and locking by locking nut, after clamping force between holder and locking plate is cancelled, its gravity is born by thrust bearing, owing to being rolling friction when thrust bearing rotates, so resistance is very little during calibration, avoid worm and gear operationally because of the stressed elastic deformation caused too greatly, ensure that the high accuracy of calibration.
5. the high accuracy pentahedron milling head of a kind of arbitrary indexing according to claim 1, it is characterized in that: radial bearing has been installed on the top that described milling head afterbody reinforcing mechanisms is included in vertical major, when main shaft tail end uses belt transmission, radial load is delivered on ring-shaped cylinder cover by radial bearing, and ring-shaped cylinder cover and swiveling head body pass through together with screw attachment, and swiveling head assembly when lathe works and holder be clamped together, therefore radial bearing obtains enough support stiffnesses; Therefore namely this pentahedron milling head can drive with motor shaft direct connection, also can by belt radial drive from the side.
6. the high accuracy pentahedron milling head of a kind of arbitrary indexing according to claim 1, is characterized in that: employ ring-like inner cylinder assembly and guide pin bushing, briquetting in described vertical major cutter-exchange mechanism and have vertical major and the four claw mechanisms of oblong aperture;
Inner cylinder assembly is by circular cylinder, ring-shaped cylinder cover, annular piston, piston rod, sealing ring first, Yx RunddichtringO, sealing ring second formed, annular piston is arranged in " U " connected in star of circular cylinder, 2 sealing rings first are housed in the groove of annular piston endoporus and cylindrical respectively, a Yx RunddichtringO, two symmetrical circular holes are had in " U " connected in star of circular cylinder, 2 piston rods are installed in hole, piston rod part contacts with the lower plane of annular piston, the upper plane contact of lower plane and guide pin bushing, annular piston and piston rod are fixed together by screw the 9th, 2 piston rods and its installing hole mating surface are sealed by 4 sealing rings the 5th, the lower plane of guide pin bushing endoporus and the upper plane contact of briquetting, move up and down in the oblong aperture that briquetting can have on main shaft, when pressure oil enters the upper oil cavitie of inner cylinder along oilhole, promote annular piston together with piston rod, guide pin bushing, briquetting is down pressed in axle first together, promote vertical four claw mechanisms descending simultaneously, handle of a knife " is spued ", otherwise when pressure oil enters the lower oil cavitie of inner cylinder, piston stroking upward, handle of a knife, under the effect of butterfly spring, is strained by four claw mechanisms.
