Description
Technical field
The utility model relates to machining equipment, particularly a kind of improvement lathe with boring bar, and described lathe can be transformed the processing to realize double end bearing socket on engine lathe.
Background technology
Much small-sized machine processing enterprise is subject to equipment of itself condition restriction to be only furnished with common lathe and there is no boring machine, when the double end bearing socket 14 of processing as shown in Fig. 1～2, because the bearing saddle bore 12 at its two requires high to axiality, the conventional machining method of existing engine lathe can not meet processing request, can only deliver to the place processing of boring machine outward, not only easily affect the manufacturing schedule of enterprise, and improve production cost, in addition own also idle cannot the making full use of of engine lathe of enterprise.In addition, the good central shaft hole 13 of double end bearing socket preprocessing before the bearing saddle bore at Boring two, this is prior art.
Utility model content
The technical assignment the utility model proposes is to overcome existing engine lathe cannot require high double end bearing socket by working axiality, can only send processing outside easily affects this enterprise manufacturing schedule, improves production cost, the idle technological deficiency that cannot make full use of of existing lathe, a kind of improvement lathe with boring bar is provided, described lathe possesses the ability of processing double end bearing socket, meet the high-axiality requirement of bearing saddle bore, and the utility model is easy to transformation realization on existing engine lathe.
The technical scheme that the utility model technical solution problem adopts: a kind of improvement lathe with boring bar, comprise a band middle carriage, the conventional lathe of rotary chuck and tailstock center, it is characterized in that fixing a base plate on described middle carriage, on base plate, have and can fix the installing hole of workpiece and be furnished with corresponding bolt, the horizontal boring bar of fixing between rotary chuck and tailstock center, boring bar left end is clamped in rotary chuck, the end face of boring bar right-hand member is opened centre bore and is withstood tailstock center, on boring bar, be provided with along its length two dismountable boring cutters, two boring cutters lay respectively at a left side for the corresponding boring bar in boring bar both sides, right two ends.By transforming existing engine lathe, on lathe, increase the special boring bar of making and guarantee that the bearing saddle bore at two ends, left and right meets coaxial requirement, existing engine lathe is made full use of, originally being completed by boring machine of task is converted into lathe processing, realize processing double end bearing socket, ensure enterprise self scheduling of production and progress, and then reduce production costs, effectively solve enterprise's processing difficulties, further improve productivity effect.When the utility model work, first before use double end bearing socket centering to be processed is fixed by bolts on base plate, then the central shaft hole of boring bar being held successfully in advance through hole seat, boring bar two ends are fixed with rotary chuck and tailstock center respectively, then start makes lathe spindle rotation, the rotation of drive boring bar, drives by the automatic walking of lathe saddle, carries out boring processing.In addition, lathe needs to pull down upper slide rest (knife rest) part before using; While processing the seat hole of double end bearing socket either side, only need on boring bar, load onto the boring cutter of a corresponding side, during as the right hole of boring, only fill boring bar right side boring cutter; Size Control method in processing is identical with common boring machine method, prior art in addition.
As further improving and supplementing technique scheme, the utility model adopts following technical measures, on described boring bar, have left dress tool bore and the right dress tool bore of corresponding two boring cutter installation positions, place, boring cutter and left and right dress tool bore are all used screw fastening, have the radial screw hole corresponding with screw on boring bar.The fastening employing screw of boring cutter on boring bar, simple in structure, convenient processing, when use inserts boring cutter dress tool bore, is then screwed into screw fastening; When boring cutter need to be dismantled, as long as screw out screw, just can pull down boring cutter.
Described left dress tool bore and right dress tool bore on boring bar side by side or shift to install.When two dress tool bores are side by side time, two hole lines are parallel to the axis of boring bar; In the time of two dress tool bore dislocation, two hole lines are the helix on boring bar surface.Due to when work boring bar rotatablely move, drive boring cutter to carry out bore hole, two dress tool bores can be side by side or the structure of dislocation, select that distribution mode to need and convenience does flexible adjustment according to reality processing.
The utility model is by the existing engine lathe of transformation, made full use of, originally being completed by boring machine of task is converted into lathe processing, realize processing double end bearing socket, ensure enterprise self scheduling of production and progress, and then reduce production costs, effectively solve enterprise's processing difficulties, further improve productivity effect.
