Specific embodiment

The preferred embodiment of the adjustable cutter chuck of the utility model such as Fig. 2, shown in Figure 3, this cutter chuck 20 comprises:

One handle of a knife 21, comprise an instrument unit section of establishing 211 and connect a set of knives section of establishing 212, and this handle of a knife 21 has a through hole 213 that is run through vertically by this instrument unit section of establishing 211, this instrument unit section of establishing 211 is coniform and is provided with cooperating and is mounted on the tool station, and this set of knives section of establishing 212 has an end face 214, this set of knives section of establishing 212 is disposed radially plural number and radially adjusts screw 215, these a plurality of screws 215 of radially adjusting are to be made as three or four, and equal angles is located at this set of knives section of establishing 212, should respectively radially adjust screw 215 is connected with this through hole 213, and the end face 214 of this set of knives section of establishing 212 is provided with axially adjustment screw 216 of plural number vertically, it is to be made as three or four that this plural number is axially adjusted screw 216, the radially adjustment screw 215 of present embodiment all is set to four with axially adjusting screw 216, and is the end face 214 that five equilibrium is arranged at this set of knives section of establishing 212 and this set of knives section of establishing 212;

One adjusts seat 22, be tubular, and this adjustment seat 22 comprises an insertion section 221 and connects a Packing Section 222, this insertion section 221 is cylindric, the internal diameter of this Packing Section 222 is extended by an end flaring that connects this insertion section 221, make these Packing Section 222 inwalls have a tapering, and the outside of this Packing Section 222 is provided with screw thread, the outside of this adjustment seat 22 radially protrudes out around being provided with one again and supports sheet 223, this adjusts seat 22 inserts this handle of a knife 21 with this insertion section 221 through hole 213, and should support the end face 214 that sheet 223 can be resisted against this set of knives section of establishing 212, and should support the relative plural through hole 224 of axial adjustment screw 216 of setting and the end face 214 of this set of knives section of establishing 212 on the sheet 223;

One collet chuck 23, the outside have tapering and an end and have folder mouthful, and the tapering of the Packing Section 222 that the taper fit of this collet chuck 23 should adjustments seat 22 is placed in the Packing Section 222 of this adjustments 22, and this collet chuck 23 has an end that presss from both sides mouth and exposed by this Packing Section 222;

One nut 24, cooperate the screw thread in 222 outsides, Packing Section of this adjustment seat 22 to be arranged at the Packing Section 222 of this adjustments 22, when this nut 24 is locked this Packing Section 222, these nut 24 these collet chucks 23 of compressing, make Packing Section 222 intrinsic displacements of this collet chuck 23 toward this adjustment seat 22, this collet chuck 23 of tapering packing of these Packing Section 222 inside convergents then makes tight-lipped the contracting so that clamping one cutter A of folder of this collet chuck 23; And

Plural number is adjusted spiral shell spare 25, be respectively and radially adjust the identical plural number of screw 215 quantity with this and radially adjust spiral shell spare 251 and axially adjust the identical plural number of screw 216 quantity with this and axially adjust spiral shell spare 252, should each radially adjust the insertion section 221 of radially adjusting screw 215 and being resisted against this adjustment seat 22 that spiral shell spare 251 is arranged at the set of knives section of establishing 212 of this handle of a knife 21 respectively, this each axial spiral shell spare 252 of adjusting then is to pass this through hole 224 that supports sheet 223 respectively to be arranged at this axially adjustment screw 216, make these adjustments seat 22 generations axially or displacement radially simultaneously by adjusting this each degree of locking of radially adjusting spiral shell spare 251 and axially adjusting spiral shell spare 252, the adjustment spiral shell spare 25 of present embodiment is a countersink head screw.

When using this cutter chuck 20, this adjustment seat 22 cooperates this collet chuck 23 and nut 24 that this cutter A is set, when this nut 24 is in relaxation state and is not urged to this collet chuck 23 as yet, the folder mouth of this collet chuck 23 is open, just the cutter A that institute's desire is used can be inserted the folder mouth of this collet chuck 23 this moment, cutter A screws this nut 24 after inserting again, when this nut 24 screws, this nut 24 contracts the folder of this collet chuck 23 is tight-lipped, then this collet chuck 23 just can clamping be located this cutter A, and when if linearity is not enough after this cutter A clamping, as shown in Figure 4, the central axis of this cutter A is crooked and when not parallel with the central axis of this handle of a knife 21, so can cause the path of this cutter A feeding crooked, influence machining accuracy, at this moment, if the degree of locking that is arranged at the adjustment spiral shell spare 25 in the two relative axial adjustment screws 216 is inequality, should support sheet 223 can be than the end face 214 near this set of knives section of establishing 212 in adjusting the darker side of locking of spiral shell spare 25, and opposite side will be than the end face 214 away from this set of knives section of establishing 212 relatively, so will cause the angle of this adjustment seat 22 crooked, and the crooked angle that also just is equal to this cutter A of the angle of this adjustment seat 22 changes, and changes this cutter A correcting by this angle of adjusting seat 22.

In addition, as shown in Figure 5, adjustment is arranged at this and radially adjusts the concentricity that screw 215 interior adjustment spiral shell spares 25 just can be adjusted this cutter A and this handle of a knife 21, push against the insertion section 221 of the adjustment seat 22 in the through hole 213 that is inserted in this handle of a knife 21 by this adjustment spiral shell spare 25, push against the displacement that this insertion section 221 produces radially this adjustment seat 22, use the concentricity of adjusting this cutter A and this handle of a knife 21, when the concentricity of cutter A and handle of a knife 21 is not enough, continue under the situation of processing, manufacturing tolerance continues accumulation, make accumulated error increasing, when the concentricity that promotes cutter A and handle of a knife 21, just can eliminate the generation of accumulated error, machining accuracy is promoted relatively, radially adjust spiral shell spare 251 not only just in order to improve the concentricity of cutter A and handle of a knife 21 and adjust this, otherwise, directly radially adjusting spiral shell spare 251 by this is adjusted into this cutter A with this handle of a knife 21 and is eccentric state, then this cutter A just can carry out eccentric processing, convenient in the extreme, because this radially adjusts screw 215 is end faces 214 that five equilibrium is arranged at this set of knives section of establishing 212 and this set of knives section of establishing 212 with axially adjusting screw 216, therefore those adjust screw 215, the 216th, relative in twos, so adjusting this adjustment seat 22 o'clock, can reach balance easily, be more convenient for adjusting.

In sum, adjustable cutter chuck provided by the utility model can reach above-mentioned all function really, has met the patent application important document really, and the whence proposes patent application in accordance with the law, requests and gives examination and grant quasi patent early, and the true feeling moral just.
