Description

The invention relates to a machine tool industry and may find application in machine tools for protecting guide working bodies.

The aim of the invention is to expand the technological capabilities of the machine by expanding the range of standard sizes of machined parts by moving the guides of the sections.

FIG. 1 shows the device with the lowest position of the movable body, a general view; figure 2 - section aa in figure 1; ny FIG. 3 — device with the lowest position of the movable organ and raised sections, general view; figure 4 - the same, with the extreme upper position of the movable body.

The device contains guides 1 of a movable body - a support 2, telescopically connected sections 3-b of box-shaped form, placed in guide elements 7 mounted on the frame of the machine 8 with the possibility of longitudinal movement.

One extreme section 3 is fixed on the support 2, and on the frame 8 it is installed at

linear displacement waters, such as a ram cylinder 9, the movable element of which — the piston 10 — is rigidly connected with another extreme section 6, which is connected with the guide elements 7.

The device works as follows.

When the caliper 2 moves downward, the working fluid is supplied to the cavity of the power cylinder 9, the piston will move downwards. In this case, section 6 with guiding elements 7 will move to the lowest position, allowing support 2 to process the parts near the pin. When machining high parts, the caliper 2 rises (Figs. 3 and 4), the working fluid flows into the cavity on the other side of the piston, which, moving upwards, moves section 6 and guide elements 7 to the extreme upper position, freeing the working space for the part. This allows the caliper 2, carried along with sections 3-5, to rise up to its extreme upper position and to work the part as far as possible from the spindle (fig.4).
