Abstract
The invention relates to a high-precision overstable numerically controlled milling machine. The longmen bracket and the machine body of the well-known numerically controlled milling machine are usually made of metal; an electric main shaft sliding plate and a workbench sliding plate slide on a beam linear guide rail on the bracket and a machine-body linear guide rail on the machine body; and as the metal has larger deformation because of temperature variation and load increase and decrease, mould processing precision is greatly affected. The longmen bracket and the machine body of the milling machine of the invention are both integrally cast and shaped by marble, the beam linear guide rail and the machine-body linear guide rail are respectively inlaid in a marble beam and the marble machine body so as to reduce deformation of the milling machine, and realize high precision and strong shock resistance. The numerically controlled milling machine has the advantages of high precision, small deformation, favorable stability, strong load capability and the like.
Description
Technical field
The present invention relates to a kind of high accuracy, overstable CNC milling machine, be specially adapted to the high-precision mold manufacture field.
Background technology
At present, known milling machine generally all is to make shell and support with metal, especially the crossbeam in the portal frame, support and lathe bed, big and load increase and decrease amount has produced certain deformation greatly the time in variations in temperature, some deformation that surpasses elastic limit then becomes permanent deformation, influence the precision of milling machine, to the product processed influence greatly, thereby people wish to have a kind of milling machine that can overcome above-mentioned shortcoming to come out.
Summary of the invention
For the support that solves CNC milling machine produces the problem of permanent deformation with temperature and load increase and decrease amount when big, the invention provides a kind of novel numerical control milling machine.
To achieve these goals, technical scheme of the present invention comprises that electric main shaft, electric main shaft, electric main shaft slide plate, crossbeam, column, lathe bed, lathe bed linear guides, table slide, rotary table, crossbeam linear guides constitute.The lathe bed and the portal frame of milling machine are all adopted the marble integral casting forming, and the lathe bed linear guides is embedded among the marble lathe bed, and the crossbeam linear guides is embedded among the marble crossbeam.
Advantage such as the present invention has that precision height, deformation are little, good stability, load capacity are strong.
Description of drawings
Accompanying drawing 1 is master's TV structure schematic diagram of the present invention.
Accompanying drawing 2 is that A-A in the accompanying drawing 1 is to cutaway view.
Accompanying drawing 3 is plan structure schematic diagram of the present invention.
In the accompanying drawing, 1 is electric main shaft, and 2 is electric main shaft slide plate, and 3 is crossbeam, and 4 is column, and 5 is lathe bed, and 6 is the lathe bed linear guides, and 7 is table slide, and 8 is rotary table, and 9 is the crossbeam linear guides.
The specific embodiment
The present invention is applied to the VMH200 Mould Machining with among the high-speed precision digital control milling machine, at first, establishment and correct input and debugging routine are in computer control device, secondly mould is correctly located, is clamped on the rotary table 8, the 3rd, under the driving of program, 1 rotation and the upper and lower motion of electricity main shaft, 2 side-to-side movements on crossbeam linear guides 9 of electricity main shaft slide plate have table slide 7 front and back motion on lathe bed linear guides 6 of rotary table 8, finish three-shaft linkage or four-axle linked processing.Because crossbeam 3, column 4 and the lathe bed 5 artificial marble integral casting forming of portal frame among the present invention, thereby crossbeam 3 and support 4 vary with temperature that the deformation ratio metal system portal frame that produces under the situation with the load increase and decrease and lathe bed are little must be a lot, thereby improved the precision of milling machine.And the portal frame of marble integral manufacturing and lathe bed 5 are stronger than metal shock resistance, have improved the stability of milling machine.Crossbeam linear guides and lathe bed linear guides are embedded in respectively among marble crossbeam 3 and the marble lathe bed 5, have reduced the deformation of track, have improved the precision of track.Greatly improved the precision of CNC milling machine by design of the present invention.
