Description of drawings:
Fig. 1 is the A-A view (front view) of a kind of planet milling cutter of the present invention.
Fig. 2 is the B-B view (vertical view) of a kind of planet milling cutter of the present invention.
The specific embodiment:
The following stated is merely preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
The planet milling cutter is seen Fig. 1, Fig. 2, comprises main spindle box 1, rotary main shaft 2, apotting spindle 3, trip bolt 4, center bearing bracket 5, support bracket bolt 6, round nut 7, divides cutter spindle 8, planet sleeve 9, gland screw 10, bearing gland 11, oil sealing 12, bearing 13, rotary head 14, support inner oil seal 15, bolt 16, cover plate 17 and support outer oil seal 18.Among the present invention: apotting spindle 3 is arranged in the hole of rotary main shaft 2, rotary head 14; 3 centering of rotary head 14 usefulness apotting spindles; Be connected with rotary main shaft 2 through trip bolt 4; Center bearing bracket 5 is connected with main spindle box 1 through support bracket bolt 6; The bolt 16 that cover plate 17 is arranged through 12 horizontal circumference equal intervals is connected with rotary head 14; Planet sleeve 9 is connected with rotary head 14, cover plate 17 through laterally zygomorphic pair of bearings 13; Pair of bearings 13 is compressed by the laterally zygomorphic bearing gland 11 of correspondence respectively up and down; Metal (upper gland 11 is that the gland screw 10 that is uniformly distributed with on the horizontal circumference of the centre of gyration is fastening with cover plate 17, rotary head 14 respectively by the six roots of sensation with the axis of minute cutter spindle 8 respectively, between planet sleeve 9 and the gland 11 oil sealing 12 is housed, and planet sleeve 9 is connected with center bearing bracket 5 through gear pair; Divide cutter spindle 8 to insert in the planet sleeve 9, divide cutter spindle 8 in the taper hole of planet sleeve 9 bottoms, to locate, rely on the flat transmission milling moment of cutting of taper shank bottom by taper shank; Divide cutter spindle 8 to be connected with planet sleeve 9, divide the outside, cutter spindle 8 bottoms that the spiral cutting sword of dextrorotation is arranged, between center bearing bracket 5 and the rotary head 14 support inner oil seal 15 is housed by the round nut 7 that two end faces are in contact with one another; Between center bearing bracket 5 and the cover plate 17 support outer oil seal 18 is housed, by two round nuts 7, divide assembly that cutter spindle 8, planet sleeve 9,12 gland screws 10, pair of bearings gland 11, a pair of oil sealing 12, pair of bearings 13 form the axis that equidistantly is arranged in rotary main shaft 2 of totally six groups and these six groups of assemblies be on the horizontal circumference of the centre of gyration.There is the beveled gear teeth of a circle dextrorotation in the outside, center bearing bracket 5 bottoms.Dividing cutter spindle 8 middle parts is taper shank, cuts flatly between taper shank and the spiral cutting sword, and there is screw thread in the outside, upper end.There is the left-handed beveled gear teeth of a circle in the outside, planet sleeve 9 middle parts, and lower inside has taper hole, and the taper hole lower inside is cut flat.
Under the drive of the rotary main shaft 2 that rotates continuously; Rotary head 14 rotates continuously; Element round nut 7 on the rotary head 14, branch cutter spindle 8, planet sleeve 9, gland screw 10, bearing gland 11, oil sealing 12, bearing 13, bolt 16, cover plate 17 are all with the axis rotation of rotary head 14 around rotary main shaft 2; And center bearing bracket 5 is connected with main spindle box 1; Therefore center bearing bracket 5 does not rotatablely move; Being that center bearing bracket 5 is static, is again that gear pair is connected between planet sleeve 9 and the center bearing bracket 5, so planet sleeve 9 and the branch cutter spindle 8 that is connected with it are except that also rotating around self axis around the axis rotation of rotary main shaft 2 is; Divide cutter spindle 8 bottoms to have the spiral cutting sword to accomplish cutting; The rotary processing of planet milling cutter motion is the resultant motion that rotatablely moves that rotatablely moves and divide cutter spindle 8 of rotary head 14 like this, and the six roots of sensation divides cutter spindle 8 except that also around self axis rotation around the axis rotation of rotary main shaft 2, and slabbing is accomplished in the feed motion of the rotary processing resultant motion cooperation platen of planet milling cutter jointly.
Oil sealing 12, support inner oil seal 15, support outer oil seal 18 all seal.The round nut 7 that adopts two end faces to be in contact with one another connects branch cutter spindle 8 and mainly plays the locking effect of friction with planet sleeve 9.
The dextrorotation beveled gear teeth engagement in the left-handed beveled gear teeth in the outside, planet sleeve 9 middle parts and the outside, center bearing bracket 5 bottoms; Not only can reduce the shock and vibration of engagement itself; And during planet milling cutter main story; More than two gear teeth engagements can produce downward additional axial force; This additional axial force can be divided the axial cutting force that make progress of cutter spindle 8 in cutting process by partial equilibrium; This axial cutting force and branch cutter spindle 8 have directly passed to main spindle box 1 at the partial vibration that cutting process produces through center bearing bracket 5, have reduced these power and the influence of vibration to rotary head 14 and alternation of hosts's axle 2 effectively, thereby have improved the machining accuracy of whole planet milling cutter.
Since cutting be accomplish by the spiral cutting sword of minute cutter spindle 8 bottoms and cut workpiece while rotate; So straight sword is directly cut workpiece and has been reduced cutting force effectively, reduced heat in metal cutting; Simultaneously to divide cutter spindle 8 to be interrupted cutting workpiece be every branch cutter spindle 8 to the six roots of sensation in process cutting workpiece time and cutting workpiece time is not arranged all; This helps heat radiation; The planet milling cutter has promptly reduced cutting force and has reduced not only heat in metal cutting radiating effect but also good simultaneously like this, realizes the high efficiency milling so under the situation of same lathe output torque, can strengthen cutting data.
