| 摘要 |
<p>The present invention relates to an isoparallelometre with at least a tool holding support, comprising: a base (1); a load bearing column (2) mounted on the base (1); a central block (3) engaged to the load bearing column (2); at least an arm (38) engaged to the central block (3); and at least a tool holding support (41) engaged to the arm (38). The central block (3) is translatable along the load bearing column (2), between a first position (5a) wherein the central block (3) is situated in correspondence with the base (1), and a second position (5b) wherein the central block (3) is situated in correspondence with an end (6) of the load bearing column (2) opposite to the base (1). The arm (38) is slidingly translatable in a horizontal plane and is free to rotate in a horizontal plane. Actuating means (7) are provided to translate the central block (3) between the first position (5a) and the second position (5b). The actuating means (7) comprise: a support element (8); a lead screw (9), having its own vertical longitudinal axis; and rotation means (10) to rotate the lead screw (9) about its own axis. The lead screw (9) is rotatorily sustained by the support element (8) and is operatively engaged in a corresponding nut screw (11) obtained in the central block (3). The tool holding support (41) is rigidly mounted to one extremity of the arm (38), and a second tool holding support (42) is provided, rigidly mounted to the other extremity of the arm (38), the tool holding supports serving as stops for the translation of the arm (38). The tool holding support (41) is free to move according to independent cylindrical coordinates.</p> |
