Abstract
The invention relates to a compound guide rail which comprises a body (9). An upper roller guide rail (3) and a lower roller guide rail (8) are installed at the two ends of the body (9), and a roller screw rod (5) is installed in the middle. A tightness adjusting device is also installed on the body (9) between the upper roller guide rail (3) and the lower roller guide rail (8). A crossbeam supporting device (2) and a vertical adjusting device (4) are installed on the upper roller guide rail (3) and the lower roller guide rail (8). The compound guide rail greatly improves the sensitivity, rigidity, antivibration force, carrying capacity and blending moment resistance ability of the relative movement between the crossbeam and a sliding saddle. Therefore, the compound guide rail is simple and reliable; ensures that moving parts not only respond sensitively, but also have high rigidity and good vibration damping property; and can meet the need of different processing environment such as heavy cutting and finishing process and so on.
Description
Technical field
The invention belongs to the Digit Control Machine Tool field of components, particularly relate to a kind of guide rail.
Background technology
The most important performance characteristic of lathe is exactly precision, rigidity, stability and service life.And guide rail is in important position to Effect on Performance always, present technology of Machine Tool field, there is multiple new structure to occur, as from the extensive use of spherical guide, roller guide several years ago, inlay strip structure, new working media and the research of lubriation material to up-to-date automatic adjustment degree of tightness, gap.As the guide rail of machine tool functional component, the structure which type of selects for use is being brought into play very important effect to realizing lathe function.
Guide rail must have higher guiding accuracy, high rigidity, high-wearing feature, characteristic such as lathe does not vibrate when high speed feed, do not creep during the low speed feeding.The guide rail of Digit Control Machine Tool use at present mainly contains 3 kinds: plastics rail plate, rolling guide and hydrostatic slideway.
1, plastics rail plate
At present, the employed rail plate material of Digit Control Machine Tool is a cast iron to plastics or edge steel to the plastics rail plate.Guide rail plastics polytetrafluoroethylene (PTFE) guide-soft-band commonly used and wear-resisting guide rail coating two classes of epoxy type.
(1) characteristics of polytetrafluoroethylene (PTFE) guide-soft-band
1) frictional behavior is good: the sound friction factor of metal-polytetrafluoroethylene (PTFE) guide-soft-band is constant substantially.
2) antiwear characteristic is good:
3) vibration damping is good: the damping capacity of plastics is good, and the better performances of its effectiveness in vibration suppression, noise elimination helps improving movement velocity.
4) good manufacturability: can reduce hardness and surface quality requirement, and plastics are easy to processing (mill, dig,, scrape), make the good surface quality of guideway contact-making surface acquisition to the metallic matrix of pasting plastics.
But rail plate is not lubricated smooth, and load is more greatly the phenomenon that may occur creeping, so the polytetrafluoroethylene (PTFE) guide-soft-band is widely used in the motion guide rail of middle-size and small-size Digit Control Machine Tool.
2. rolling guide
(1) structure of straight-line rolling guide set and characteristics rolling guide have following characteristics as a class of rolling friction pair: 1. friction factor little (0.003-0.005), motion are flexibly; 2. dynamic and static friction factor is basic identical, thereby starting reactance is little, creeps and be difficult for producing; 3. can pretension, the rigidity height; 4. the life-span is long; 5. precision height; 6. lubricated convenient, can adopt grease lubrication, once to load, oil lubrication also can be adopted regularly, quantitatively be carried out to long-term the use; 7. produce by the special manufacturer, can outsourcing select for use.Therefore rolling guide-rail pairs is widely used on precision machine tool, Digit Control Machine Tool and the measuring machine.
The major defect of rolling guide-rail pairs is that the ability of resistance to shock loads and antidetonation is relatively poor, and rolling guide-rail pairs is responsive to dust bits end etc., and the favorable protection cover should be arranged.
3. hydrostatic slideway
To be the fluid that will have a certain pressure be transported to the oil pocket of guide pass through flow controller to hydrostatic slideway, forms the carrying oil film, and the metal surface that is in contact with one another is separated, and realizes fluid friction.The friction factor of this guide rail little (about 0.0005), the mechanical efficiency height: owing between guide pass one deck oil film is arranged, absorbing is good; Guide pass is not in contact with one another, and can not wear and tear, and the life-span is long, and operation also is difficult for producing creeping under low speed.
But the hydrostatic slideway complex structure, the pressure adjustment bothers relatively, and is that higher to the lathe requirement of shelter, total manufacturing cost is higher.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple, reliable, make moving-member not only respond sensitivity, and rigidity is strong, and shock absorption is good, satisfies the composite guide rails of different processing environment needs such as heavy cut and fine finishining.
A kind of composite guide rails, comprise body (9), two of body (9) be equipped with respectively roller guide (3) and, following roller guide (8), roller screw mandrel (5) is equipped with in the centre, be positioned on the described body (9) between roller guide (3) and the following roller guide (8) slack adjuster also is housed, described going up on roller guide (3) and the following roller guide (8) is equipped with crossbeam holding device (2) and vertical adjusting device (4).
Described crossbeam holding device (2) is a briquetting.
Described vertical adjusting device (4) is an adjusting pad.
Described slack adjuster is by filler rod (6) and adjust screw (7) formation.
Beneficial effect
Crossbeam of the present invention will relatively move with saddle, effectively utilized and be the function that the linear roller guide of the big specification of vertically arranged two groups is born guiding, off-load and born live load, ball-screw transmits moment of torsion, and uses the filler rod between two roller guides and adjust secondary vibration resistance, rigidity and the operating load ability of strengthening of rail plate that screw is formed.With vertically arranged linear roller guide rail is that the basis adds filler rod and adjusts the secondary composite guide rails of forming of rail plate that screw is formed, and improves sensitivity, rigidity, antivibration power, load force and the bending resistance square ability of relative motion between crossbeam and the saddle greatly; So the present invention is simple, reliable, make moving-member not only respond sensitivity, and rigidity is strong, shock absorption is good, satisfies the needs of different processing environments such as heavy cut and fine finishining.
