  • Fig. 4 is an elevation view of the adaptor of Fig. 3.
  • Figs. 5(A) to (F) are various views of components of a cutting tool assembly including an adaptor according to another embodiment of the invention. Description of Preferred Embodiments
  • the cutting tool assembly shown in Figs. 1 and 2 includes a shank 10, a head 12 on which is mounted a cutting insert 14, and an adaptor 16.
  • the shank 10 has a square cross-section and at its operative end includes a transverse groove in a side face thereof defined by side walls 18 which slope towards each other to a base surface 20.
  • a bore 19 passes through the shank 10, from an opposite side face to that containing the transverse groove, to the base surface 20 of the transverse groove and this bore 19 includes an enlarged portion 21 for reception of the head of a draw bolt as will be described below.
  • the groove defined by side walls 18 and base surface 20 is for receiving a male bearing portion of the adaptor 16 to be more fully described below.
  • the adaptor 16 includes a body formed to provide a rearwards male bearing portion 22 and having a groove in the form of female slideway 24 formed therein in a forwards surface.
  • the male bearing portion 22 comprises side surfaces 26 which slope towards each other and an end surface 28.
  • the included angle of surfaces 26 is preferably 60° and equals the included angle of sloping side walls 18 of the transverse groove in the shank 10.
  • the female slideway 24 is orthogonally orientated relative to the bearing portion 22 and comprises side walls 30 which slope inwardly to a base 32.
  • the included angle of side walls 30 is preferably 60°.
  • the adaptor also includes means in the form of a locating plate 34 (see Figs. 1 and 2 - not shown in Figs. 3 and 4) which is attached to an end face 36 of the bearing portion 22 (see Fig. 4) by set screws 38 engaging in tapped holes 39.
  • a bore 40 extends through adaptor 16 from end surface 28 of bearing portion 22 to base 32 of female slideway 24.
  • the locating plate 34 ensures bores 19 and 40 are aligned when the adaptor 16 is assembled with shank 10. Any suitable means may be provided on the adaptor 16 for locating it relative to a shank 10 for aligning the bores 19 and 40.
  • the male bearing portion 22 of the adaptor 16 provides a first connection means for mounting the adaptor on the shank 10 and the female slideway 24 provides a second connection means for a head to be mounted on the adaptor as will now be described.
  • Head 12 is the same as described in Application No. PCT/AU96/00234 and reference should be made to this prior application for a full description of the head.
  • the bearing portion 42 of head 12 includes sloping surfaces which match walls 30 of slideway 24 and an end surface which is spaced a small distance from the base 32 of the slideway 24.
  • a draw bolt 44 is passed through bore 19 in shank 10 and bore 40 in adaptor 16 and screwed into engagement with an adjusting mechanism of the head 12 (as fully described in PCT/AU96/00234) to clamp the head 12 to the adaptor 16 and the adaptor 16 to the shank 10.
  • Tightening bolt 44 brings its head into engagement with the shoulder in bore 19 at the junction with bore 21 and this causes the bearing portion 42 of head 12 to be drawn into and wedged within female slideway 24 of adaptor 16 and concomitantly for bearing portion 22 of adaptor 16 to wedge within the groove 18-20 in shank 10.
  • the shank 10 may be configured to provide for quick assembly and quick disassembly of a head 12, adaptor 16 and bolt 44 combination. This may be provided by converting bore 19-21 in the shank 10 into a groove which is open at the top surface (with reference to Fig. 1) of the shank 10. Thus, quick disassembly is achievable by simply loosening draw bolt 44 and then relatively lifting the head 12/adaptor 16/bolt 44 combination off the shank 10.
  • a shank which provides this facility is more fully described in Application No. PCT/AU97/00695 and reference should be made to this application for further details. As illustrated by Fig. 1 , the described combination provides for a cutting insert 14 to be located in a plane parallel to that of the shank 10.
  • the cutting insert 14 is adjustable in a direction parallel to the longitudinal axis of the shank.
  • the head 12 may also be mounted directly on the shank 10 (by engagement of its bearing portion 42 in the transverse groove defined by walls 18-20) which will locate the cutting insert 14 in an orthogonal plane to that of the shank 10.
  • the adaptor 16 increases the versatility of a cutting tool assembly as it provides a wider range of set up and adjustment options.
  • FIG. 5(A) shows a head 12 having a cutting insert 14 which is generally similar to the head of figures 1-4 and is a head as described in PCT/AU96/00234.
  • Figs 5(C) and (D) show two forms for a shank 10 which include a quick assembly and disassembly groove as described above, which is indicated by reference 46.
  • the shanks 10 are for mounting in the tool post of a cutting machine.
  • the shank of Fig. 5(C) provides for mounting of an adaptor 16 (see Figs 5(B), (E) and (F) at an angle to the axis of the shank rather than orthogonally as in the Fig. 5(D) shank.
  • the adaptor 16 (shown in top plan view in Fig. 5(B), side elevation in Fig. 5(E) and end elevation in Fig. 5(F) is generally similar to that of Figures 1- 4 except that it has a circular cross section body 48 (see Fig. 5(F)). Body 48 can be extended longitudinally to give a larger separation between male bearing portion 22 and female slideway 24. Similarly, the adaptor of figures 1- - 6 -
  • the orthogonally directed female slideway 24 may be angled relative to the longitudinal axis of the adaptor, for example in the plan view of Fig. 5(B), the slideway 24 may be orientated such that head 12 is angled at 45° to the longitudinal axis of adaptor 16.
  • the shank may have a cross- section which is other than square or the first connection means may have a female instead of a male form and correspondingly the second connection means may have a male instead of a female form.
  • Other variations, modifications and/or additions may also be made and it is to be understood that the invention includes all such variations, modifications and/or additions which fall within the scope of the following claims.

Abstract

L'invention porte sur un adaptateur pour un ensemble outil coupant utilisé dans des opérations de découpe du métal telles que le tournage, le saignage, le filetage, l'alésage, le dressage, etc. Cet adaptateur (16) permet d'avoir une meilleure souplesse d'utilisation du manche (10) et de la tête amovible (12) supportant un élément d'insertion coupant (14) de l'ensemble outil coupant. En montant l'adaptateur entre le manche et la tête, l'orientation de la tête par rapport au manche se modifie facilement. L'adaptateur comprend une partie (22) de raccordement mâle qui se coince dans une gorge (18) du manche, et une glissière (24) dans laquelle s'emmanche une partie (42) support de la tête lors du montage de l'outil. La partie de raccordement mâle et la glissière de l'adaptateur sont orientées pratiquement orthogonalement de façon à modifier l'orientation de la tête par rapport au manche de pratiquement 90°. Un ensemble outil coupant à montage et démontage rapides est également décrit et revendiqué.
