MACHINE TOOL WITH TURNABLE MOVABLE SECTION

Title:

MACHINE TOOL WITH TURNABLE MOVABLE SECTION

Document Type and Number:

WIPO Patent Application WO/2007/148620

Kind Code:

A1

Abstract:

A high rigidity tilt function is achieved while the advantage of tandem drive is sustained without increasing the control shafts more than the number of shafts corresponding to tandem shafts. Feeding of the movable section of a parallel mechanism having two-degree-of-freedom is achieved. A first movable section base (12) is screwed to a first feed screw shaft (14) and a second movable section base (22) is screwed to a second feed screw shaft (24). A spindle head (31) is coupled with the first movable section base (12) to oscillate freely by a supporting shaft (18). A linking shaft (33) at the distal end of a lever (32) extending downward from the spindle head (31) is coupled rotatably with the guide piece (29) of an oblique linear guide (28) provided on the second movable section base (22) and linked with the second movable section base (22).
