Description
Technical field
The utility model relates to mechanical production devices, z axle composite guide rail structure in the lathe.
Background technology
Same group of guide rail of Digit Control Machine Tool generally is all rail plate or is all rolling guide.Digit Control Machine Tool is exactly good, enough rigidity of guiding accuracy height, precision stability and good frictional behavior to the basic demand of guide rail.Wherein frictional behavior is exactly not only to want coefficient of friction little, also wants static and dynamic friction coefficient approaching as far as possible, to reduce frictional resistance and guide rail thermal deformation, makes motion light, and low speed does not have creeps.For satisfying above-mentioned requirements, Digit Control Machine Tool generally adopts the rail plate or the rolling guide of the sticking wear-resistant plastic of edge.
The rail plate of the sticking plastics of edge has good rigidity, vibration resistance height, and wearability, the anti-tear ability of wound are strong, and processability and chemical stability are good, technology is simple, cost is low, and good advantages such as self-lubricating are arranged, but the situation of creeping relatively easily appears, and the relative positioning precision of moving component is lower.
Rolling guide and rail plate major advantage Comparatively speaking is:
1, sensitivity is good, and the lag time that drives between signal and mechanical action is extremely short, the response speed and the sensitivity that help improving digital control system.
2, the power of drive motors is descended significantly, driving power is equivalent to about 1/10th of common rail plate.It is compared with the rectangle rail plate, and coefficient of friction can descend about 40 times.
3, the lathe of be applicable at a high speed, high accuracy being processed, instantaneous velocity can improve about 10 times than rail plate, thereby can realize the lathe requirement of high position precision and repetitive positioning accuracy.
4, can realize not having the gap motion, improve the kinematic accuracy of feed system.
When 5, rolling guide uses in pairs, have the error leveling effect, thereby reduce basic part (guide rail installed surface) requirement on machining accuracy, reduce the machine-building cost and the difficulty of basic part.
The guide rail structure of existing lathe feed shaft is as shown in Figure 1: lathe main guide rail 1 and teach rail 7 to be all rail plate, on rail plate 1 edge of the bed ways 7 on top and bottom, all paste wear-resistant plastic 4, the upper surface of bed ways 7 and guide rail 1 at grade, fixedly wedge 3 is located on the edge in the bed ways 7 on saddle 2 corresponding tops, and at saddle 2 corresponding guide rail stile end places, with same structure fixedly wedge 6 and pressing plate 5, wedge 10 and pressing plate 9.
Summary of the invention
The purpose of this utility model provides a kind of composite guide rail structure of lathe feed shaft, and configuration is slided and the two kinds of guide rails that roll on the same feed shaft of lathe, and the advantage separately of comprehensive two kinds of guide rails is optimized machine tool feed guide rail structure and performance.
The composite guide rail structure of this lathe feed shaft, there are leading screw, top that saddle is arranged in the middle of the bed ways, the bed ways upper level that it is characterized in that the leading screw outside does not wait, bottom lathe bed main guide rail is made as rail plate, interior along placing fixedly wedge down, the rolling guide of rail is taught on top, lathe bed inclined-plane by the fixing conduct of guide rail clip; Relatively wear-resistant plastic is pasted at the guide rail position on the saddle, the wedge place is screwed pressing plate relatively, the rolling guide place is by the fixing rolling guide groove of adjustment member relatively, and the driven by motor leading screw drives saddle moves the realization lathe on two guide rails axial feed.
The composite guide rail structure of lathe feed shaft: present most of numerically controlled lathe feed shaft generally is furnished with two and is all rail plate or rolling guide, saddle moves axially in the guide rail upper edge, characteristics of the present invention are that the guidance rail on bed piece top is set to rolling guide, lathe bed bottom main guide rail is set to rail plate, and are furnished with guide rail and adjust link.Lathe when if cutting force is less than a certain numerical value in the turner process rolling guide play a major role and overcome cutting force, cutting force during greater than a certain numerical value rail plate and rolling guide work simultaneously and overcome cutting force, lathe hour can be brought into play high speed, the high accuracy characteristic of rolling guide at cutting force like this, can bring into play the high rigidity and the high stability of rail plate when cutting force is big.
This composite guide rail structure combines the advantage separately of two kinds of guide rails, has optimized the structure and the service behaviour of lathe.
