| 摘要 |
<p>The present invention refers to a machine for tooling internal grooves comprising a structural body (E) on which a set of two superimposed carriages (1 and 2) is mounted having synchronized movement one in relation to the other according to axial and transversal directions in respect of the structural body (E), the set of carriages (1 and 2) being responsible for the fastening of a spindle (F) to be internally grooved, said spindle (F) being retained together with the set of carriages (1 and 2) by a caliper (3) mounted in a dragging tube (7), said dragging tube being in its turn mounted inside the set of carriages (1 and 2); actuation of the caliper (3) being provided by a lever (8) controlled by a hydraulic cylinder (9) which acts against the effort of resilient means (10), said dragging tube (7) being axially displaceable in respect of said structure (E), and caliper (3) being rotatable in 360° in respect of said longitudinal or axial shaft of the structural body (E).</p> |
