Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of cutter chuck.
Realize technical scheme of the present invention as follows:
A kind of cutter chuck, comprise knife bar, collet chuck, nut, described collet chuck is divided into leading portion, back segment, collet chuck back segment outer surface is taper seat, described knife bar is axially arranged with the internal taper hole A suitable with the external taper of collet chuck back segment, the front portion of knife bar is provided with external screw thread A, collet chuck back segment clamping is in internal taper hole A, the axial centre of described nut is provided with through hole, the back segment of through hole is provided with internal thread A, nut is arranged on the front end of collet chuck and is threaded with the external screw thread A of knife bar by internal thread A, the outer surface of described collet chuck leading portion is taper seat, taper seat is provided with external screw thread B, described through hole leading portion is have internal thread B and the internal taper hole B suitable with collet chuck leading portion taper seat, collet chuck leading portion realizes being threaded with coordinating of internal thread B by external screw thread B with the through hole leading portion of nut, internal thread B on the through hole leading portion of described nut is contrary with the hand of spiral of the internal thread A on through hole back segment, and the hand of spiral of the through hole back segment of nut is contrary with the rotation direction of stage property chuck.
Further, annular groove is provided with between described collet chuck leading portion and the large end face of back segment.
Further, the through-hole wall between the through hole leading portion of described nut and back segment is provided with the circumferential clasp to through hole radial protrusion.
Have employed above-mentioned scheme, collet chuck leading portion is threaded with the through hole leading portion of nut, collet chuck rear end clamping is in the internal taper hole of knife bar, the through hole back segment of nut is threaded with knife bar, by two places be threaded realize cutter chuck respectively form between connective stability, when cutter chuck high-speed rotation, though produce larger vibration, the nut of cutter chuck also can not easily loosen, and effectively improves the chucking power of cutter chuck and the stability of clamping.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1 is knife bar, and 2 is collet chuck, and 3 is nut, and 4 is collet chuck leading portion, and 5 is collet chuck back segment, and 6 is internal taper hole A, and 7 is through hole leading portion, and 8 is through hole back segment, and 9 is annular groove, and 10 is circumferential clasp.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As Fig. 1, a kind of cutter chuck, comprise knife bar 1, collet chuck 2, nut 3, described collet chuck is divided into leading portion 4, back segment 5, collet chuck back segment outer surface is taper seat, described knife bar is axially arranged with the internal taper hole A6 suitable with the external taper of collet chuck back segment, the front portion of knife bar is provided with external screw thread A, collet chuck back segment clamping is in internal taper hole A, the axial centre of described nut is provided with through hole, through hole back segment 8 is provided with internal thread A, nut is arranged on the front end of collet chuck and is threaded with the external screw thread A of knife bar by internal thread A, the outer surface of described collet chuck leading portion is taper seat, taper seat is provided with external screw thread B, described through hole leading portion 7 is for having internal thread B and the internal taper hole B suitable with collet chuck leading portion taper seat, collet chuck leading portion realizes being threaded with coordinating of internal thread B by external screw thread B with the through hole leading portion of nut, internal thread B on the through hole leading portion of described nut is contrary with the hand of spiral of the internal thread A on through hole back segment.
In order to make the connection between collet chuck and nut more stable, annular groove 9 is provided with between described collet chuck leading portion and the large end face of back segment, through-hole wall between the through hole leading portion of described nut and back segment is provided with the circumferential clasp 10 to through hole radial protrusion, by the axial limiting realized between collet chuck and nut that cooperatively interacts of annular slot and circumferential clasp.In order to realize being threaded smoothly of collet chuck leading portion and nut leading portion, the broadband of annular slot is greater than the broadband of circumferential clasp.
Structure of the present invention is simple.During assembling, first by Cutting tool installation manner in collet chuck, then collet chuck leading portion is threaded with the through hole leading portion of nut, then by collet chuck rear end clamping in the internal taper hole of knife bar, last fastening nut makes the through hole back segment of nut be threaded with knife bar, thus make cutter tightly clamping in cutter chuck.Because the internal thread B on the through hole leading portion of described nut is contrary with the hand of spiral of the internal thread A on through hole back segment, and the hand of spiral of the through hole back segment of nut is contrary with the rotation direction of stage property chuck, while fastening nut, due to tightening of nut and coordinating of annular slot and circumferential clasp, collet chuck continuous screw propulsion forward in the internal taper hole of knife bar.
Because the hand of spiral of the through hole back segment of nut is contrary with the rotation direction of cutter chuck, when cutter chuck high-speed rotation, cutter chuck produces vibration, under the effect of vibration, collet chuck is for departing from knife bar, and be threaded between collet chuck with nut further tight, nut together rotates in company with collet chuck.In addition, because the internal thread B on the through hole leading portion of described nut is contrary with the hand of spiral of the internal thread A on through hole back segment, be threaded between nut with knife bar and become tight.By two places be threaded realize cutter chuck respectively form between connective stability, even if produce larger vibration, the nut of cutter chuck also can not easily loosen, and effectively improves the chucking power of cutter chuck and the stability of clamping.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
