Description
Technical field
The present invention relates to a kind of improvement of pentahedral machining machine tool, specifically, relate to a kind of high-precision pentahedral machining machine tool.
Background technology
The guide rail of existing high-precision pentahedral machining machine tool is bilinear rolling guide or three linear rolling track structures; Bilinear rolling guide structure when load-carrying is big, the table surface easy deformation; For installation three linear rolling track structures, its bed piece, the necessary coplane of table surface, this has just proposed higher requirement to the machining accuracy of bed piece, workbench, and its processing cost also will improve.
The right-angle milling head of existing pentahedron machining center lathe needs ram to run to ad-hoc location when tool changing, could realize with the auxiliary cutter-removing mechanism that is installed on the column; Because right-angle milling head is subjected to unidirectional external force during tool changing, can the precision of lathe be impacted for a long time; Need right-angle milling head and tool magazine accurate positioning simultaneously, the necessary accurate positioning of right-angle milling head and auxiliary tool changing device simultaneously is so assembly difficulty is big, interchangeablity is poor.
A storehouse housing of existing pentahedron machining center lathe is directly to expose from column, strengthens changing a stroke and taking up room of lathe, has strengthened transverse beam casting parts length and guide rail stroke, makes to change a speed reduction.
Summary of the invention
Main purpose of the present invention is at the problems referred to above, the high-precision pentahedral machining machine tool that provide a kind of machining accuracy height, can cut down finished cost.
Another object of the present invention is at the problems referred to above, stable accuracy is provided, assembles the good high-precision pentahedral machining machine tool of interchangeability easy, machine part.
A further object of the present invention is at the problems referred to above, and a kind of taking up room, shorten transverse beam casting parts length and guide rail stroke, improving speed of changing head and the high-precision pentahedral machining machine tool of saving cost of lathe of reducing is provided.
Main purpose of the present invention is achieved in that and comprises bed piece, workbench, crossbeam, left column, right column, electric control box, console, main transmission box, ram, planker, tool magazine, automatic head storehouse, right-angle milling head and chip cleaner; Be provided with guide rail between bed piece and the workbench; The automatic head lab setting is on right column; Guide rail comprises the linear rolling track that is arranged at the bed piece left and right side respectively and is arranged at a middle edge steel rolling guide of bed piece; Be provided with the workbench stopping means between bed piece and the workbench and regulate screw mandrel; Edge steel rolling guide comprises the fixed block of inlaying bloom, scroll box and scroll box, and the edge bloom is fixed on the pedestal of bed piece, and scroll box is fixed on the fixed block of scroll box, and the fixed block of scroll box is fixed on the downside table top of workbench; Between the downside table top of the fixed block of scroll box and workbench, be provided with adjusting pad.
Another object of the present invention is achieved in that right-angle milling head includes right-angle milling head housing and right-angle milling head main shaft, the right-angle milling head main shaft is fixedly installed in the right-angle milling head housing by bearing, bearing holder (housing, cover), be provided with the pull bar of sheathed butterfly spring at the center of right-angle milling head main shaft, the right-hand member of this pull bar connects claw; Also include the oil cylinder device for loosing knife, the oil cylinder device for loosing knife comprises gland, piston, end cap, cylinder block and plane bearing; Cylinder block is fixed in bearing holder (housing, cover), and end cap and cylinder block suit are fixed, and are provided with spacer between gland and piston; The gland that is connected on the piston promotes to be connected with the plane bearing of the left end installing of pull bar, and constitutes the structure that oil cylinder hydraulic promotes piston, piston drive gland pushing drawing rod pine cutter.
A further object of the present invention is achieved in that head-shield support and the head-shield that the automatic head storehouse comprises cylinder, places right-angle milling head in the storehouse housing, slides near switch, along support guide; Storehouse case lid is provided with dust cap, and cylinder is provided with dust cover; Storehouse housing comprises a storehouse portion and an embedding part, embedding part insert lathe right column perforate and constitute the syndeton that an embedding part of storehouse housing is embedded in right column inside.
The invention has the beneficial effects as follows:
1), the bilinear rolling guide or the three linear rolling track structures of X-axis guide rail different from the past, it has set up an edge steel rolling guide in the centre of two linear rolling tracks; With respect to bilinear rolling guide structure, the structure of an edge steel rolling guide had bigger rigidity in the middle of both sides bilinear rolling guide added, and can effectively prevent the table top distortion when load-carrying is big; With respect to three linear rolling track structures, solved the lathe bed that three guide rails are installed, the problem of the necessary coplane of table surface, under same installation processing conditions, X-axis precision and rigidity can not descend, simultaneously, the cost of edge steel rolling guide is also much lower than the cost of linear rolling track;
2), owing to be provided with the oil cylinder device for loosing knife, could loose cutter so do not need to arrive ad-hoc location, so assembling interchangeability easy, machine part is good;
3), because the automatic head storehouse has half to be in the inside of right column, outsidely only expose a square storehouse portion; This storehouse can realize whether on the throne from the action of moving head-shield and right-angle milling head if can detect head-shield and right-angle milling head; Owing to be positioned at the position before the right column, make the volume-diminished that exposes in a storehouse, the position at close lathe center also makes a stroke that changes of lathe reduce, and has reduced taking up room of lathe, shortened transverse beam casting parts length and guide rail stroke, improved the speed of changing head and saved cost.
Thereby the present invention has the machining accuracy height, assembles the advantage that takes up room, improves the speed of changing head that interchangeability easy, machine part is good, reduce lathe.
The invention will be further described for following embodiment accompanying drawings.
