Tool shank retention mechanism with machine tool therefor

A simple, strong and fast acting tool retention subsystem is intended for both original equipment and retrofit applications in machining centers with automatic tool changer systems. A machining center incorporating the invention is described. The invention is compatible with ANSI standards for spindles, tapered tool shanks and knobs, and is configured to eliminate the tool chatter and tool shank taper unseating and release commonly occurring in conventional spring actuated tool retention subsystems when spiral fluted cutters are used. The tool shank is positively jam locked by a rotary bolt actuator means that generates a very high value of axial pre-load tension, comparable to that which was furnished by the very successful historic manual draw-in bolt retention subsystem used in milling machines. A bi-directional free wheeling impact motor drives the rotary bolt actuator means between open and closed positions of a maximally strong collet. Positive seating of the tool shank in the spindle nose taper is assured by the extremely high pre-load tension applied to the knob, which is supplied by the mechanical strain of the steel of the jam locked mechanism and the supporting spindle structure. Thus the tool retention is limited only by the yield strength of the materials and not by the bias of any coil or belleville spring, as is the current practice in the machining center industry.

Manual device for unclamping tool

A manual tool unclamping device is provided to prevent risk caused due to a rotation arm serving as a tool exchange unit during rotation of a cam. A manual tool unclamping device comprises a draw bar(30), a cam(110), a link(100), a link moving unit(25), a draw bar moving unit(20), and a link operation unit. The draw bar is movable in a vertical direction so as to unclamp a tool from a collet. The cam is automatically rotatable by a driving source. The link has a hinge shaft(102) which is pushed in an upward direction by the variation of the radius of the cam contacting a roller(101). The link moving unit is connected to the link, and converts rotation performed centering from the hinge shaft of the link into vertical motion. The draw bar moving unit moves the draw bar in a downward direction by the downward motion of the link moving unit. The link operation unit lifts the link so that the link is spaced apart from the cam. The manual tool unclamping device unclamps or clamps the tool from the collet by permitting one end of the link to be spaced apart from the cam and the other end of the link to press the link moving unit so that the draw bar moves in a downward direction by the draw bar moving unit.

Device for detachably fit tool to machine spindle

FIELD: mechanical engineering. SUBSTANCE: device is intended for fitting a tool in metal working machine spindle provided with precision hole concentric relative to the spindle axis. It has a precision journal entering the precision hole and is provided with two clamping pins mounted in the journal to move radially in opposite directions, with clamping member adopted to be displaced axially with the aid of clamping mechanism situated on the spindle side, with two wedge-shaped surfaces positioned from one side on the clamping member and from the other side on the clamping pin, inclined relative to the spindle axis and mating each other by pairs for radial displacement of the clamping pin between the released and clamped positions. To enable fitting of big tools with considerable clamping force even in case of relatively short axial path for the clamping mechanism situated on the spindle side, it is foreseen in the invention that the wedge-shaped surfaces of the clamping member and the clamping pin are provided with a groove limited by lateral sides. This groove divides the wedge-shaped surfaces respectively into two partial surfaces positioned at a definite distance from each other. With the device in the released position one partial surface comes in engagement with the opposite lateral groove following the pattern of gearing and with the device in the clamped position both wedge-shaped surfaces mate each other by pairs.

Diese zeichnet sich dadurch aus, dass die Spannvorrichtung (19) einen Zugbolzen (41) und ein diesen in axialer Richtung verlagerndes Exzenterelement (21) aufweist, wobei das Exzenterelement (21) über eine Umfangsfläche (17) des Zerspanungswerkzeugs (1) betätigbar ist. It is an interface between two sub-elements of a tool system, in particular a Zerspanungswerkzeugs (1), with a recess (31) having a holder (3) and one in the recess (31) insertable extension (33) comprehensive, in axial displacement to the holder (3) arranged replaceable head (5) and with a clamping device (19) for fixing the replaceable head (5) on the holder (3) proposed. This is characterized in that the tensioning device (19) has a tension bolt (41) and an eccentric element (21) displacing it in the axial direction, wherein the eccentric element (21) can be actuated via a peripheral surface (17) of the cutting tool (1).

Interface between two parts of a tool system

The invention relates to an interface between two parts of a tool system, in particular to a metal cutting tool ( 1 ). Said interface comprises a holder ( 3 ) provided with a cavity ( 31 ), an interchangeable head ( 5 ) which is arranged on the axial extension of the holder and provided with a projection ( 33 ) introducible into the cavity ( 31 ) and a clamping device ( 19 ) for fixing the interchangeable head ( 5 ) to the holder ( 3 ). The inventive interface is characterised in that the clamping device ( 19 ) is provided with a holding bolt ( 41 ) and an eccentric element ( 21 ) which axially displaces said bolt and is actuated through a peripheral surface ( 17 ) of the metal cutting tool ( 1 ).
