A kind of column and knee type CNC milling machine with three axis rails
Technical field
This utility model relates to a kind of milling machine, a kind of column and knee type CNC milling machine with three axis rails.
Background technology
Milling machine refers mainly to the lathe using milling cutter to process kinds of surface on workpiece, generally milling cutter rotary motion is main motion, the movement of workpiece and milling cutter is feed motion, milling machine can process plane, groove, various curved surface, gear etc. can also be processed, can also process more complicated profile, efficiency relatively planer is high, is used widely in machine-building and repairing department.Along with the development of science and technology, people investigated CNC milling machine, uses the work process of program-control milling machine, and milling machine can be divided into column and knee type milling machine, the desk-top milling machine of planer-type milling machine, not lifting work, watchmaker's milling machine etc..Column and knee type CNC milling machine is a kind of milling machine that people commonly use, although existing column and knee type CNC milling machine meets the use demand of people, it is all to be supported by hard rail when but in existing CNC milling machine, workbench carries out reciprocating motion all around, the coefficient of friction of hard rail is big, it is difficult to the quick mobile of workbench, and workbench easily weares and teares, service life is short.
Summary of the invention
The purpose of this utility model is to provide a kind of column and knee type CNC milling machine with three axis rails, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of column and knee type CNC milling machine with three axis rails, including base, lathe bed, fixed plate, lifting platform, semi-girder, adjust head, milling head transmission case, digital control system and servomotor, described base is positioned at lowermost end, lathe bed is arranged on the upper end of base, the upper end of lathe bed is provided with semi-girder, adjust head and fixed plate is installed on semi-girder, servomotor is arranged on the upper end of fixed plate, wired rail is installed in fixed plate, in line rail, slide block is installed, milling head transmission case is connected with fixed plate by contiguous block, servomotor lower end is provided with ball-screw and ball-screw is connected with slide block, lifting platform is arranged on the front of lathe bed, workbench is arranged on the upper end of lifting platform by slide block, wired rail is installed between slide block and lifting platform, digital control system is arranged on lathe bed.
As further program of the utility model: be provided with main shaft on milling head transmission case, servomotor is arranged in fixed plate by support.
As further program of the utility model: between fixed plate and semi-girder, all fixed by screw between milling head transmission case and contiguous block.
Compared with prior art, the beneficial effects of the utility model are: this device is reasonable in design, failure rate is low, safety in utilization and good operation stability;Detachability is good, it is easily installed and operational maintenance, line rail and slide block is used between workbench and lifting platform, coefficient of friction when workbench is moved between X-axis, Y-axis and Z axis reduces, thus realize the quick mobile of workbench, accelerating work efficiency, extend the service life of workbench, using effect is good.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
nullRefer to Fig. 1-2,A kind of column and knee type CNC milling machine with three axis rails,Including base 1、Lathe bed 2、Fixed plate 11、Lifting platform 3、Semi-girder 6、Adjust head、Milling head transmission case 8、Digital control system 5 and servomotor 7,Described base 1 is positioned at lowermost end,Lathe bed 2 is arranged on the upper end of base 1,The upper end of lathe bed 2 is provided with semi-girder 6,Adjust head and fixed plate 11 is installed on semi-girder 6,Servomotor 7 is arranged on the upper end of fixed plate 11,Wired rail is installed in fixed plate 11,Slide block 10 is installed in line rail,Milling head transmission case 8 is connected with fixed plate 11 by contiguous block,Servomotor 7 lower end is provided with ball-screw and ball-screw and is connected with slide block 10,Lifting platform 3 is arranged on the front of lathe bed 2,Workbench 4 is arranged on the upper end of lifting platform 3 by slide block 10,Wired rail is installed between slide block 10 and lifting platform 3,Digital control system 5 is arranged on lathe bed 2.Being provided with main shaft 9 on milling head transmission case 8, servomotor 7 is arranged in fixed plate 11 by support.Between fixed plate 11 and semi-girder 6, all fixed by screw between milling head transmission case 8 and contiguous block.
Operation principle of the present utility model is: use line rail and slide block 10 in this device between workbench 4 and lifting platform 3, coefficient of friction when workbench 4 is moved between X-axis, Y-axis and Z axis reduces, thus realizing the quick mobile of workbench 4, coefficient of friction reduces the service life also extending workbench 4.This device is reasonable in design, failure rate is low, safety in utilization and good operation stability;Detachability is good, it is easily installed and operational maintenance, line rail and slide block 10 is used between workbench 4 and lifting platform 3, coefficient of friction when workbench 4 is moved between X-axis, Y-axis and Z axis reduces, thus realize the quick mobile of workbench 4, accelerating work efficiency, extend the service life of workbench 4, using effect is good.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art is possessed, it is also possible to various changes can be made on the premise of without departing from this patent objective.
