High-precision vertical Linear guide rail of lathe of the prior art mechanism, its mounting means is too simple, and its installed surface is all in same plane, and the support stiffness of this installation is poor, can not embody the kinematic accuracy of line slideway, thereby the precision of processing parts is exerted an influence.
Utility model content
The utility model provides a kind of NC vertical lathe guiding rail mechanism, its objective is the support stiffness and the stability that improve guide rail.
To achieve these goals, the technical scheme that the utility model is taked is:
NC vertical lathe guiding rail mechanism of the present utility model, described vertical lathe comprises crossbeam, knife rest, and described guiding rail mechanism comprises three line slideways and setting parallel to each other, and described knife rest moves on crossbeam by described three line slideways; Three described line slideways are not in same plane.
In three described line slideways two, be arranged on crossbeam just before, parallel distribution before and after its guide rail mating surface becomes, and the guide rail mating surface of straight line guide rail is below positioned at the inclined to one side anterior position of crossbeam, the guide rail mating surface of straight line guide rail is above positioned at the straight line guide rail below position after partially, forms ladder and distributes;
Straight line guide rails assembling is directly over crossbeam in addition, and the guide rail mating surface of its guide rail mating surface and aforementioned two line slideways forms vertical relation.
Described be arranged on crossbeam directly over the height of line slideway, higher than two remaining straight lines guide rail.
The utility model adopts technique scheme, strengthened the joint stiffness between guide rail, guaranteed rigidity, stability and the kinematic accuracy of knife rest in rectilinear motion process, thereby dwindled to greatest extent kinematic error, realized high accuracy transmission, the machining accuracy that effectively raises knife rest, has improved operating efficiency, has met the needs of high-precision numerical-control vertical lathe.
Accompanying drawing explanation
Below the expressed content of each width accompanying drawing of this description and the mark in figure are briefly described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of structure shown in Fig. 1;
Fig. 3 is the guide rail mating surface of three guide rails distribution map on its cross section.
In figure, be labeled as:
1, crossbeam, 2, knife rest, 3, servomotor, 4, shaft coupling, 5, motor cabinet, 6, ball screw, 7, bearing block, 8, line slideway, 9, guide rail mating surface.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technical scheme.
Expressed structure of the present utility model, is a kind of NC vertical lathe guiding rail mechanism as shown in Figure 1, Figure 2, and described vertical lathe comprises crossbeam 1, knife rest 2, servomotor 3, shaft coupling 4, motor cabinet 5, ball screw 6, bearing block 7; Servomotor 3 is arranged on motor cabinet 5,7 of motor cabinet 5 and bearing blocks be arranged on crossbeam 1 before, for supporting and fixing ball screw 6; Servomotor 3 is given power transmission to be fixed on crossbeam 1 ball screw 6 above by shaft coupling 4, thereby drives knife rest 2 moving linearly on crossbeam 1.High-precision numerical-control vertical lathe combined type guiding rail mechanism is one of the most indispensable parts in modernization high-precision vertical lathe structure member.
In order to solve the problem of prior art existence and to overcome its defect, realize and improve the support stiffness of guide rail and the goal of the invention of stability, the technical scheme that the utility model is taked is:
As shown in Figure 1 and Figure 2, NC vertical lathe guiding rail mechanism of the present utility model, described guiding rail mechanism comprises three line slideways 8 and setting parallel to each other, described knife rest 2 moves on crossbeam 1 by described three line slideways 8; Three described line slideways 8 are not in same plane.
Combined type line slideway is main element of the present utility model, between knife rest 2 and crossbeam 1, by three line slideways 8, connect, and these three guide rails is each other in the same space plane,
The position relationship of these three line slideways 8, has fully guaranteed stationarity, motion rigidity and the reliability of knife rest 2 when rectilinear motion, thereby has dwindled to greatest extent kinematic error just, has realized high accuracy transmission.This structural relation has strengthened the joint stiffness between guide rail greatly, has also just guaranteed motion rigidity and the precision of knife rest 2 in motion process.
Referring to Fig. 3:
In three described line slideways 8 two, be arranged on crossbeam 1 just before, 9 one-tenth parallel distributions in front and back of its guide rail mating surface, and the guide rail mating surface 9 of straight line guide rail 8 is below positioned at the inclined to one side anterior position of crossbeam 1, the guide rail mating surface 9 of straight line guide rail 8 is above positioned at the straight line guide rail 8 below position after partially, forms ladder and distributes;
In addition straight line guide rail 8 be arranged on crossbeam 1 directly over, 9 one-tenth vertical relations of guide rail mating surface of its guide rail mating surface 9 and aforementioned two line slideways 8.
9 one-tenths of guide rail mating surfaces that connect three line slideways 8 between knife rest 2 and crossbeam 1 are parallel to each other and vertical relation, wherein two line slideways 8 be arranged on crossbeam 1 just before, 9 one-tenth front and back of guide rail mating surface are parallel, and lower height, upper low ladder relation; Other one be mounted in crossbeam 1 directly over, guide rail mating surface 9 with above two become vertical relation.
As shown in Figure 3: described be arranged on crossbeam 1 directly over the height of line slideway 8, higher than two remaining straight lines guide rail 8.
Article three, line slideway 8 is separately fixed at its slide block and guide rail on knife rest 2 slides and crossbeam 1 with screw and the voussoir of M16.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
