MACHINE TOOL FOR MOUNTING TOOL RELATIVE TO BLANK Russian patent published in 1997 - IPC

FIELD: machine engineering. SUBSTANCE: machine tool includes pair of mutually spaced platforms. One platform (2,20,125,54,100,87) may carry working member such as tool in spindle; other platform (1,19,120,111,89,104) - worked object such as part to be worked. Said mutually spaced platforms are joined by means of six extensible supports (9-14, 24-29, 46-51, 90-95, 107,122,124,127-129) provided with power drive and connected with respective platform by ball joints. Length values of said supports are adjusted separately for changing position of platforms and therefore worked objects and working member one relative to another along six axes. Said supports with power drive may be in the form of hydraulic cylinders (9-14) or they may be moved by means of ball type leading screw (31, 134, 135). Distance between platforms may be measured with use of separate tool holding levers (81, 82, 112) connecting platforms. Said tool holding levers may use digital mounting apparatus (166, 168) for measuring lengthening and shortening of tool holding levers or interferometer including laser light source may be used for the same purpose. Change of length values of tool holding levers may be used for generating signals controlling lengthening or shortening degree of moved supports. Method of converting orders of unit for matching partial program to orders for changing length of moved supports is also considered. EFFECT: improved design. 8 cl, 21 dwg
