The slide construction of this machine tool dragging plate is mainly to offer guide slide by the medial surface at rail plate, pressing plate is positioned at the inner side of rail plate, at the lower limb of pressing plate, guiding rib is set, this guiding rib coordinates slip with guide slide, pressing plate is built-in with respect to rail plate, saved the horizontal space of lathe, lathe head of a bed transmission case body span diminishes, and has improved the life-span of machining accuracy and lathe.
In the slide construction of above-mentioned a kind of machine tool dragging plate, the arris place, interior long limit of described rail plate offers corner groove, above-mentioned planker lower surface offer relative with above-mentioned corner groove connect against step, described be connected in the groove of corner against step guiding.
In the slide construction of above-mentioned a kind of machine tool dragging plate, be provided with the triangle oblique rail that leads at the above-mentioned wherein upper surface of a rail plate, the lower surface of planker be provided with above-mentioned triangle lead oblique rail coordinate slide triangle gathering sill, described triangle gathering sill is connected to triangle and leads on oblique rail.
In the slide construction of above-mentioned a kind of machine tool dragging plate, the lead outer surface of oblique rail of described triangle is provided with graphite linings.The main purpose that graphite linings is set is to contribute to the lead slip of spigot surface of oblique rail of triangle gathering sill and triangle, improves both slide coefficients.
Compared with prior art, the slide construction of this machine tool dragging plate mainly offers respectively guide slide at the medial surface of two rail plates, the lower surface of planker is installed with two pressing plates corresponding with above-mentioned rail plate, the lower limb of pressing plate has the guiding rib that can be connected in guide slide, and guiding rib is connected in above-mentioned guide slide; The utility model, simple in structure, save the horizontal space of lathe, lathe head of a bed transmission case body span diminishes, and has improved machining accuracy, long service life.
