Technical field
The utility model relates to the machining apparatus technical field, relates in particular to a kind of Digit Control Machine Tool.
Background technology
In traditional Digit Control Machine Tool; The last slide carriage of lathe is carrying the bistrique frame and on the direction vertical with workpiece spindle box of edge, is moving; Its positioning accuracy direct relation the machining accuracy of workpiece, so the fit structure of itself and middle slide plate is one of important factor in order of machine finish.At present, said bindiny mechanism of going up between slide carriage and the lathe middle slide plate has three types: one type is bilateral dovetail guide groove; Another kind of is a side dovetail groove, the hard rail of a side rectangle; Also have one type to be that a side adopts " V " type groove guide rail and the hard rail of opposite side employing rectangle.Preceding two types dove-tail form guide-track groove positioning accuracy is relatively poor, and it in use makes fit clearance increasing owing to constantly wear and tear, and needs the wedge structure in special elimination gap; This makes troubles to use; Wherein second type because a side is used the hard rail of rectangle, and when operating force is big, the vertical component of its operating force will go up on the slide carriage easily and lift; This has not only limited grinding wheel speed, and bite is also had than limitations.The 3rd type because a side is used the hard rail of rectangle, has limited rotation at a high speed and full depth amount grinding action equally, and in use for some time, because the V-type groove is inharmonious with rectangular channel traffic direction after wearing and tearing, can cause the increase of machine tooling error.The common defects of above-mentioned three types of bindiny mechanisms be can not be in use compensate for wear amount automatically, and make progressively variation of positioning accuracy.
The utility model content
The technical problem that the utility model will solve is, a kind of new Digit Control Machine Tool is provided, and the syndeton between its middle slide plate and the last slide carriage has the automatic backlash compensate function, therefore can guarantee the grinding turning accuracy of bistrique frame and knife rest.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of Digit Control Machine Tool; Comprise middle slide plate, be located at the last slide carriage on said middle slide plate top and be located at the said bistrique frame of going up on the slide carriage; Its characteristics are; Said middle slide plate top is provided with two " V " type grooves in the axis normal direction of edge and said bistrique frame, and said bottom of going up slide carriage is provided with two " V " type guide rails that match with said two " V " type grooves, and said " V " type guide rail and said " V " type groove are slidingly connected.
The beneficial effect of the utility model is: owing to adopt two " V " type guide rail structures; Its guiding accuracy is high; Steering capability is good; Occur under the situation of trace wearing and tearing in use for some time, the gravity of slide carriage and bistrique frame can be realized the self-compensating function in the utilization, makes it have good positioning accuracy retentivity.This structure is in grinding process in addition, in the bite scope that allows, and the stock removal of emery wheel, perhaps the cutter bite is big more, and compressing of V-type groove is good more, so this stability of structure is good, can improve the machining accuracy of lathe greatly.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, said " V " type guide rail is provided with the right angle shoulder, and said right angle shoulder is provided with pressing plate, and said pressing plate is fixed on the said middle slide plate.
Adopt the beneficial effect of above-mentioned further scheme to be, can adjust the compressing degree of guide rail and groove through pressing plate.
Further, the two sides and the right angle shoulder of said " V " type guide rail are provided with the guide rail band.
Adopt the beneficial effect of above-mentioned further scheme to be, adopt wear-resisting guide rail band can reduce the frictional force between guide rail and the groove, and can effectively prevent the wearing and tearing of guide rail and groove.
Further, said going up on the slide carriage also is provided with knife rest.
Adopt the beneficial effect of above-mentioned further scheme to be, make this lathe have grinding and turning processing dual-use function.
Further, the said slide carriage bottom of going up is provided with vertical ball-screw drive unit.
Adopt the beneficial effect of above-mentioned further scheme to be, this configuration can cooperate the jockey of the utility model effectively to guarantee the grinding carriage positioning accuracy.
