Slide cover apparatus for machine tool

摘要

A slide cover apparatus for partitioning a machining head unit from a workpiece support unit comprises first and second cover assemblies. A main board and plural sub-boards of the first cover assembly are telescopically movable in a first horizontal direction, and the main board is formed with a vertically extending rectangular window. A center board and plural sub-boards of the second cover assembly which cover the rectangular window are guided by the main board for vertical movement. The main board is connected with a cross slide table of the machining head unit which is movable in the first horizontal direction, so as to be moved bodily by the cross slide table, while the center board is connected to be moved by a spindle head of the machining head unit. The spindle head on which a tool spindle is rotatably carried extending in a second horizontal direction perpendicular to the first horizontal direction is guided for vertical movement by a column, which is movable on said cross slide table in the second horizontal direction. The center board is formed with a tool-path hole which permits the tool spindle to pass therethrough, whereby the machining head unit is partitioned from the workpiece support unit except for the tool-path hole.
