Description
Technical field
The utility model belongs to Metal Cutting Machine Tool technical field, especially relates to a kind of follow-rest device for gantry horizontal lathe.
Background technology
In tradition engine lathe, knife rest is fixed on little supporting plate, then little supporting plate, horizontal supporting plate, big palette are layering on bed ways again, cause maximum machining diameter on knife rest to only have half of maximum machining diameter on lathe bed slightly many, are unfavorable for the processing of thick major axis.The movable gantry type numerical control lathe occurring at present can increase processing bar diameter range, but when processing longaxones parts, working ability is subject to certain limitation, and its less stable has especially affected machining accuracy and the scope of application of lathe.
Summary of the invention
The purpose of this utility model is: for the problem of above-mentioned existence, provide a kind of longaxones parts good stability, follow-rest device for gantry horizontal lathe that machining accuracy is high processed.
The technical solution of the utility model is: comprise portal frame, portal frame is arranged on two horizontal guide rails on lathe bed, and gantry feed arrangement is housed between portal frame and lathe bed, and gantry feed arrangement drives portal frame to move along the horizontal guide rail on lathe bed; One side of portal frame is equipped with follow-rest, follow-rest comprises follow-rest seat, rotating handles, positioning sleeve, screw rod, guide pillar, fore-set, follow-rest seat hangs the side that is arranged on portal frame, follow-rest seat top and portal frame are fixed, the bottom of follow-rest seat in the direction perpendicular to axis of workpiece, be equipped with that two groups of rotating handleses, positioning sleeve, screw rod, guide pillar, fore-set form with cutter bracing or strutting arrangement, guide pillar is by thread connection screw rod, guide pillar is installed in the pilot hole in follow-rest seat, rotating handles and screw rod are connected, and fore-set is arranged on the top of guide pillar.
Further, follow-rest seat top is arranged on portal frame by fixing pin, one group of rotating handles, positioning sleeve, screw rod, guide pillar, fore-set be arranged on workpiece above, another group rotating handles, positioning sleeve, screw rod, guide pillar, fore-set be arranged on workpiece after.
The beneficial effects of the utility model are: the utility model adopts follow-rest to hang the side that is arranged on portal frame, portal frame is arranged on the guide rail above lathe bed, gantry feed arrangement drives portal frame and follow-rest along the horizontal guide rail transverse shifting on lathe bed, portal frame moves flexibly, and while follow-rest is followed portal frame and moved.During work, by handling rotating handles, drive bolt rotary, thereby promote guide pillar and fore-set motion, fore-set is close on workpiece.When the knife rest on portal frame is processed feeding along axis of workpiece direction, follow-rest withstands workpiece on the rightabout of cutting force, prevents the flexural deformation that affects machining accuracy that long-axle workpieces occurs under the effect of Tool in Cutting power.The utility model had both increased the diameter range of processing bar, had strengthened again stability and the machining accuracy of processing longaxones parts, had increased the scope of application of lathe, controlled easy maintenance, and manufacture and use cost are cheap, was convenient to manufacture in batches and promote.
