Abstract
The utility model relates to a small size vertical machining center having new structure, which is characterized in that an open type spindle unit is used for cooling, without using a constant temperature cooling box; an upright column has a frame hollow structure; central wiring is adopted as the wiring mode between the upright column and a spindle box; a lathe bed, the upright column, the spindle box, a slide carriage and an operating platform are all in symmetrical structures; and all moving parts are driven centrally. The characteristics of symmetric structure and symmetric heat source are achieved, thereby solving the problems of influencing the precision of machine tool, such as asymmetric heat source, asymmetric deformation, vibration, and the like, caused by the asymmetric machine tool structure, and efficiently lowering the cost of machine tool and comprehensively promoting the property of the machine tool.
Description
● technical field
The utility model relates to a kind of new structure minitype vertical type machining center.
● background technology
At present, known minitype vertical type machining center structure is generally C font layout structure, and column is fixed on the lathe bed, and main spindle box moves up and down on column, and slide is the front and back motion on lathe bed, and workbench is side-to-side movement on slide.Motor lines on the main spindle box and cooling tube, lubrication management etc. are all by the main spindle box side and even are connected with column by tank.Mutual motion between column and main spindle box, slide and lathe bed, workbench and the slide is driven by the servomotor ball screw assembly,, servo-drive is in the center symmetric position a bit, some is in the non-centrosymmetry position, drive for non-centrosymmetry, and the above Wiring structure that uses, because structure is asymmetric, thermal source asymmetric, there is the deflection moment of torsion when causing the parts moving linearly motion, increased friction, the vibration between the moving component and the precision of lathe is reduced.In addition, the cooling of present known inner electric machine main axle unit is generally the independently circulation cooling that is driven by the constant temperature cooler bin, the cost height of lathe.
● the utility model content
In order to solve since the asymmetric thermal source that causes of machine tool structure asymmetric, stress deformation is asymmetric, vibration etc. is to the influence of machine tool accuracy, the problem of aspects such as lathe cost height, this utility model provides a kind of novel minitype vertical type machining center structure, reached the complete symmetrization of structure, the symmetrization that pipeline connects, the symmetrization of thermal source, and reduced the cost of lathe by the cool cycles mode that changes the inner electric machine main axle unit.
The technical solution of the utility model is: column adopts the framework hollow structure, and the cabling mode between the column main spindle box adopts the intermediate traces mode, is not with tank to connect; Column, slide, lathe bed, main spindle box structure all adopt the left-right symmetry structure; The center of gravity type of drive is all adopted in the driving of moving component; The open cycle type of cooling is adopted in the main axle unit cooling, does not need the constant temperature cooler bin.
The middle-size and small-size vertical machining centre of a kind of new structure is made of column, pipeline, drive system, cooling water inlet, coolant outlet, bearing, workbench, lathe bed, axis system, forms the structure of vertical machining centre.It is characterized in that: the open type of cooling is adopted in the main shaft cooling; Column main spindle box cabling mode adopts the intermediate traces mode; Drive and all adopt the center of gravity type of drive; Design of part adopts symmetrical structure.
Column adopts the framework hollow structure, and pipeline is in the motion of the center hollow position of column, and its tache motorice is fixed on the axis system, and stiff end is fixed on the rear end of column, and pipeline is sagging naturally, moves up and down with axis system;
The bearing type of cooling in the axis system is entered by cooling water inlet, bearing is cooled off the back flowed out by coolant outlet, flows to whole lathe inner loop system, enters circulation.
Drive system all is in the position of centre of gravity that is driven part and drives, and adopts the center of gravity type of drive.
Column, workbench, lathe bed and axis system all adopt the maximization symmetrical structure.
The beneficial effects of the utility model are: the utility model solved since the machine tool structure asymmetric thermal source that causes asymmetric, stress deformation is asymmetric, vibration etc. is to the influence of machine tool accuracy, the problem of aspects such as lathe cost height, this utility model has reached the complete symmetrization of structure, the symmetrization that pipeline connects, the symmetrization of thermal source, and, reduced the cost of lathe by changing the cool cycles mode of inner electric machine main axle unit.
