Abstract
The invention discloses a floating double-cutter cutting lathe which comprises a lathe body, a big trailing bar and a lathe chuck. The big trailing bar is arranged on the lathe body, and the lathe chuck clamps workpieces. The floating double-cutter cutting lathe further comprises knife rests, knife rest trailing bars, a knife rest trailing bar lead screw and a knife rest trailing bar lead screw adjustment handle disc. The knife rest trailing bars are arranged on the big trailing bar, the knife rests are arranged on the knife rest trailing bars, and a set of the knife rest and the knife rest trailing bar at the front portion is symmetrical with a set of the knife rest and the knife rest trailing bar at the rear portion, that is, the front knife rest and the front knife rest trailing bar are symmetrical with the rear knife rest and the rear knife rest trailing bar. Identical cutting knifes are arranged on the positions, where the circle section of the workpiece is equally divided in a 180-degree mode, of the front knife rest and the rear knife rest to guarantee equal and balance force when the two cutting knifes conduct cutting. According to floating double-cutter cutting lathe, the single-knife machining method in the prior art is replaced by a double-knife machining method, cutting machining efficiency is increased twice on the premise that workpieces can bear the force, and machining accuracy can be improved due to that fact that vibration becomes smaller.
Description
Technical field
The invention belongs to axle class or class Machining of Shaft-type Parts machine tool technology field, be specifically related to a kind of lathe that carries out cylindrical or outer face high-efficient cutting for shaft-like workpiece.
Background technology
At present, carry out class axle class slender piece add man-hour with engine lathe, because such workpiece rigidity is less, the radial load that cutting produces and peripheral force make workpiece produce distortion, then cause vibration; Have to adopt and reduce the methods such as cutting speed and reduce vibration and carry out machining.This has not only reduced production efficiency, also affects machining accuracy simultaneously; Particularly add the more outstanding of performance in man-hour at slender axles.
Summary of the invention
The above-mentioned technical problem existing in order to overcome prior art field, the object of the invention is to, and a kind of Double-cutter head Cutting lathe that floats is provided, production efficiency is high, the vibration of effectively having avoided processing to cause, is ensureing, under the prerequisite of machining accuracy, to have improved significantly production efficiency simultaneously.
Unsteady Double-cutter head Cutting lathe provided by the invention, it comprises parts more than former engine lathe saddle, it also comprises knife rest, tool rest carriage, tool rest carriage leading screw and tool rest carriage leading screw are adjusted handle chassis, described tool rest carriage is arranged on saddle, described knife rest is arranged on tool rest carriage, before knife rest and tool rest carriage are symmetrically arranged with, latter two groups: front rest and front rest planker, back tool rest and back tool rest planker, before described, back tool rest is separately installed with an identical bite in the position of 180 ° of equal portions of workpiece section circle, guarantee two bites when cutting stressed to isoequilibrium, the footpath outward force being subject to reach balance workpiece.
Unsteady Double-cutter head Cutting lathe, described tool rest carriage leading screw adjustment handle chassis is arranged on the front end of tool rest carriage leading screw; Described tool rest carriage leading screw is arranged between tool rest carriage and saddle, tool rest carriage leading screw is provided with screw thread and axial location facility, screw thread is arranged on the two ends of tool rest carriage leading screw, wherein one end is set to left-hand thread, the other end is set to right-hand thread, swivelling tool-holder planker leading screw is adjusted handle chassis (if on numerically controlled lathe, numerical control feeding device also can be installed), and forward and backward tool rest carriage can enter and move back in lathe radial direction equidimension simultaneously.
The axial location facility arranging on described tool rest carriage leading screw is floating control mechanism, floating control mechanism can be arranged on front portion, the middle part of tool rest carriage leading screw, any place at three places, rear portion, can make screw mandrel keep fixing or move about by the adjustment handle of this mechanism, when in fixed position, ensure that forward and backward two knife rests initially equate lathe spindle heart center; When adjusting to can move about time, can make tool rest carriage screw mandrel move forward and backward vertically certain distance, make forward and backward two knife rests drive two bites to move about simultaneously, make the shape of two bites or the radial load difference that dress cutter error produces, be tending towards substantially equating and acting on the dynamic balance on workpiece.
Described forward and backward knife rest is provided with general handle of a knife clamping position, limit, left and right, and two bites can be faster installed, and point limit, left and right installation, can meet to the needs of head of a bed direction or the processing of tailstock direction.
Unsteady Double-cutter head Cutting lathe provided by the invention, its beneficial effect is, reduces the radial load that processing produces, thereby has reduced processing vibration, then can improve cutting speed; Become double-pole processing from original hilted broadsword processing, the machining efficiency that can be enhanced about more than once under the prerequisite of the stressed license of workpiece, and because vibration is little, can improve machining accuracy; Owing to having increased the dress cutter facility of reverse feed processing, carry out anti-feed processing for slender rod type workpiece, the vibration that the unstability after can avoiding elongate rod stressed produces, can further improve working (machining) efficiency.
