Description
Technical field
The utility model relates to machine tool clamping field of components, is specifically related to a kind of Cutting tool installation manner and changes cutter chuck easily.
Background technology
The cutter chuck of current use comprises knife bar, collet chuck, nut substantially, and the handle of a knife of cutter inserts in collet chuck, and collet chuck clamping is in knife bar, nut is threaded with knife bar, collet chuck is pushed ahead by nut in the process of tightening, and makes collet chuck be forced to contracted diameter, thus is clamped by the handle of a knife of cutter.When changing cutter, need cutter chuck to disassemble from lathe, then nut, collet chuck are all being disassembled and could change cutter, process is more loaded down with trivial details, is also like this, greatly reduces operating efficiency during Cutting tool installation manner.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of Cutting tool installation manner and changes cutter chuck easily.
Realize the technical solution of the utility model as follows:
A kind of Cutting tool installation manner changes cutter chuck easily, comprise knife bar and collet chuck, described collet chuck is tapered collet, internal thread is provided with bottom collet chuck, the axial centre of described knife bar is provided with infundibulate central shaft hole, infundibulate central shaft hole be divided into cylindrical hole and and the bellmouth suitable with the external taper of tapered collet, collet chuck clamping is in bellmouth, the cross bar that can move axially is provided with in described cylindrical hole, the bottom of cylindrical hole is provided with spring, one end of cross bar is connected with collet chuck bottom thread, the other end and spring contact, circumferential wall on cross bar is provided with a ring annular groove, described knife bar is provided with and is communicated with and vertical screwed hole with described cylindrical hole, the latch segment suitable with described groove is provided with in screwed hole, latch segment is threaded with screwed hole.
Further, described channel section is that chamfer is trapezoidal, and described latch segment is divided into two sections, and epimere is cylindrical and is threaded with screwed hole, and hypomere is truncated cone-shaped and the gradient of the hypotenuse of the gradient of round platform sidewall and groove right-angled trapezium is coincide.
Further, the height of described round platform is not more than the height of groove right-angled trapezium.
Have employed above-mentioned scheme, be threaded by collet chuck with cross bar, by regulating the latch segment degree of depth thus drive cross bar mobile to realize the locking of cross bar or to unclamp in the axial direction in a groove, it is convenient that being installed on of cutter is changed.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the exploded view of Fig. 1;
In figure, 1 is knife bar, and 2 is collet chuck, and 3 is cylindrical hole, and 4 is bellmouth, and 5 is cross bar, and 6 is spring, and 7 is groove, and 8 is screwed hole, 9 latch segments.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1, 2, a kind of Cutting tool installation manner changes cutter chuck easily, comprise knife bar 1 and collet chuck 2, described collet chuck is tapered collet, internal thread is provided with bottom collet chuck, the axial centre of described knife bar is provided with infundibulate central shaft hole, infundibulate central shaft hole be divided into cylindrical hole 3 and and the bellmouth 4 suitable with the external taper of tapered collet, collet chuck clamping is in bellmouth, the cross bar 5 that can move axially is provided with in described cylindrical hole, the bottom of cylindrical hole is provided with spring 6, one end of cross bar is connected with collet chuck bottom thread, the other end and spring contact, circumferential wall on cross bar is provided with a ring annular groove 7, described knife bar is provided with and is communicated with and vertical screwed hole 8 with described cylindrical hole, the latch segment 9 suitable with described groove is provided with in screwed hole, latch segment is threaded with screwed hole.
Further, described channel section is that chamfer is trapezoidal, and described latch segment is divided into two sections, and epimere is cylindrical and is threaded with screwed hole, and hypomere is truncated cone-shaped and the gradient of the hypotenuse of the gradient of round platform sidewall and groove right-angled trapezium is coincide.
Further, the height of described round platform is not more than the height of groove right-angled trapezium.
During assembling, first cross bar is threaded with collet chuck, then by cutter clamping in collet chuck, then aforementioned structure is assembled in the central shaft hole of knife bar, now the hypomere of latch segment just contacts with groove, finally utilize the oblique between the round platform sidewall of latch segment and the hypotenuse of groove right-angled trapezium to regulate latch segment, thus make cross bar mobile with the object reaching locking collet chuck on knife bar axis direction, cutter is like this by tightly clamping.When changing cutter, unscrew latch segment, under the reset response of spring, cross bar moves on knife bar axis direction, and collet chuck is released, and cutter just can easily be changed.
The utility model structure is simple, reasonable in design, and being installed on of cutter is changed conveniently, substantially increases operating efficiency.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model namely openly in scope; still can do some revise or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
