Description
Technical field
The present invention relates to a kind of numerically controlled lathe accessory, specifically the two X-axis of a kind of numerically controlled lathe is rebored slide saddle member.
Background technology
Along with the fast development of modern mechanical manufacturing industry, industry-by-industry, especially engineering machinery and Aero-Space industry propose requirements at the higher level to the boring deep hole machining of macrotype axes series parts on numerically controlled lathe (hereinafter referred to as lathe):
1, for improving machining accuracy, requiring that a deep hole boring puts in place, avoiding the secondary clamping error that workpiece reverses end for end to bring;
2, on a machine tool, complete many sequence processing such as boring deep hole, turning of workpiece as far as possible with clamped one time, while guarantee working (machining) efficiency, ensure the axiality of hole and cylindrical;
3, for raising the efficiency, the requirement of boring processing cutting-in and cutting feeding is improved day by day.
Existing numerically controlled lathe, adopt and on indexable cutter tower (hereinafter referred to as cutter tower), assemble lathe tool and boring bar to meet above requirement simultaneously, but the drawback of this kind of scheme is apparent: on the one hand, along with the degree of depth in boring hole strengthens, the length of required boring bar increases thereupon, under the basic norm meeting boring bar draw ratio, require that boring bar diameter also strengthens thereupon; On the other hand, on machine tool tower, the size of boring cutter bar mount pad is directly by the restriction of cutter tower size and thickness, and cutter tower often specification determine, cannot strengthen.This just brings the contradiction between the demand of large boring bar diameter and clamping length increasing and limited Installing machine tool ability, and constrain the increasing of boring bar length and clamping length on lathe, it is following unfavorable that this just brings to the boring deep hole machining on lathe:
1, boring bar length limited, if workpiece needs the darker blind hole of boring, then cannot process;
2, boring bar length limited, if workpiece needs boring comparatively deep via, means that workpiece can not machine by clamped one time, and can only adopt the method for tune processing, workpiece accuracy cannot ensure;
3, comprise various lathe tool, drill bit, screw tap, boring bar all cutters be installed on cutter tower, interfere with each other, restriction lathe workpiece adaptability; Especially long boring bar, it is longer that it takies Z axis stroke, operates careless slightly, very easily and main spindle box, protect between, the interference such as workpiece, because long boring bar is often very expensive, once collide, will bring about great losses;
4, due to boring bar diameter and clamping length limited, when overhanging longer, often vibration resistance significantly reduces, for preventing the cutter that shakes, existing way be reduce cutting-in and cut feeding, therefore working (machining) efficiency is extremely low.
The present invention designs and has invented the two X-axis of a kind of numerically controlled lathe and to rebore slide saddle member, thoroughly solves above problem.
Summary of the invention
Technical problem to be solved by this invention is, for the deficiencies in the prior art, the two X-axis of a kind of numerically controlled lathe is provided to rebore slide saddle member, it adopts modularized design, reliably simple for structure, convenient operation, while retaining traditional numeric-control lathe tool tower function completely, significantly can improve numerically controlled lathe deep hole heavy duty boring performance, machining accuracy, working (machining) efficiency and the range of work.
The present invention solves the problems of the technologies described above adopted technical scheme: the two X-axis of numerically controlled lathe is rebored slide saddle member, comprise cutter tower saddle, cutter tower slide carriage, indexable cutter tower, first X-axis driving mechanism, to rebore saddle, to rebore slide carriage, to rebore tool rest and the second X-axis driving mechanism, described cutter tower saddle is provided with the first parallel slide rail along lathe X-direction, described cutter tower slide carriage is assemblied on described cutter tower saddle and also can slides along the first described slide rail, described indexable cutter tower is arranged on described cutter tower slide carriage, the output of the first described X-axis driving mechanism is connected with described cutter tower slide carriage, described saddle of reboring is fixedly connected on the right side of described cutter tower saddle, described saddle of reboring is provided with the second parallel slide rail along lathe X-direction, described slide carriage of reboring is assemblied on described saddle of reboring and also can slides along the second described slide rail, described tool rest of reboring is arranged on described rebores on slide carriage, the output of the second described X-axis driving mechanism is connected with described slide carriage of reboring, the bottom of described cutter tower saddle and described saddle of reboring is provided with the parallel guide groove along machine Z-axis direction, described guide groove is suitable with the guide rail being arranged on bed piece, after installation, two X-axis slide saddle member of reboring is assemblied in bed piece and is connected with machine Z-axis screw mandrel.
