FIELD: machine building.SUBSTANCE: cross support table of a metal-cutting lathe comprises an upper support 1 and a lower 2 on guides 3 of a stand, an intermediate device between them in the form of a slide plate 4 with guides 5 along inner guides 6 of the stand. The slide plate via an elastic element 7, for instance, a cylindrical spring, is connected by a leash 8 with an upper support, having a through T-shaped slot 9 for the length of its travel. In the slot there is a coupled rectangular head 10 of the leash. The leash has the shape of the rod of alternating cross section with thread at the end, on which a nut 11 is screwed at the bottom of the slide plate. The compression spring 7 is installed on the leash between the slide plate and the nut. According to the other version, the elastic element is made in the form of a sheet spring with a root sheet in the form of a ski 12, which has at least one of slide plate guides. For convenience of adjustment the nut has a toothed crown, and the slide plate - a roller gear 14 engaged with it, with a head for a key.EFFECT: support table provides for take-up of clearances in all connections, even wear of guides and continuous compensation of wear.4 cl, 5 dwg |
