Abstract
The utility model relates to a straight line rolling damping vibration attenuation guide rail, which comprises a guide pair composed of a steel flat guide and roller slide blocks, characterized in that a damping block arranged between the roller slide blocks of the guide pair is a flat rail plate which is fixed with a moving component. The surface of the damping block that engaged with the steel flat guide is adhered with an abrasion-proof guide soft strip, the damping block is engaged with the steel flat guide to form a clearance of 0.02-0.03 mm and is drilled with an oil hole, and an extruding oil film is formed between the guide and the damping block. The straight line rolling damping vibration attenuation guide rail has obvious vibration damping function, improves crash safety performance, has great versatility, and is applicable for various flat guides, simple in manufacturing and convenient for spreading and applying in machine tool industry.
Description
Technical field
The utility model relates to a kind of accurate linear rolling track of lathe that is used for and pays the straight-line rolling damping vibration attenuation guide rail of the precision of raising lathe guided bearing and the resistance to shock of motion.
Background technology
In recent years, more and more higher to the requirement of lathe guidance system along with Digit Control Machine Tool and precision machined development, it is the decision key factor in machine finish, operating efficiency and service life.Many equipment choosing linear rolling tracks are as guided bearing.Because it is that gapless ball or roller slide block are paid as contacting with pretension that linear rolling track uses the guide rail that hardens, have that coefficient of friction is little, bearing capacity is big, the characteristics of good rigidly, long service life, can reach very high feed speed and positioning accuracy, now the straight-line rolling parts produced of some professional machine tool functional component factories form series, type selecting is easy, easy for installation, has been widely used on machine-tool industry and all kinds of guiding mechanism.But rolling guide is compared with traditional planar slide guide rail, and because of its rolling contact-making surface is point or line, damping property is less better relatively.For this reason, the guide rail manufacturer that has once adopted the method that increase preloads to the rolling guidance system to improve damping property, yet actual tests shows this method DeGrain.Increase preloads and has just changed resonant frequency, and vibration damping is not had much improvement; On the contrary,, strengthened the distortion of rolling element, thereby increased the guiding mechanism resistance to displacement, contact surface abrasion is accelerated, influenced the working life of director element owing to increased preloading of rolling guidance system.Another oscillation damping method is to realize by echoing damping element, as German INA company supporting a kind of damping slide on the straight line roller guide of being produced in recent years, its inner surface configuration is identical with guide rail, and sprayed a kind of sliding bearing material, during manufacturing with the guide rail match grinding that matches, make this layer sliding bearing material and pairing guide rail surface form the gap of 0.03mm, during use, in this lamellar spacing, add lubricating oil, formed oil film can play the effect of an extruding shock absorber, but planting the damping slide can only be supporting with the guide rail of INA model, and other linear rolling track can't use, and price is very expensive.
Summary of the invention
The purpose of this utility model is in order to improve the damping property of linear rolling track, to carry a kind of straight-line rolling damping vibration attenuation guide rail with good resistance to shock of being furnished with damping block of arch.
The technical solution of the utility model is finished like this, it comprises that steel flat guide and several roller slide blocks form guide rail and pay, its characteristics are: be equipped with damping block between the roller slide block that guide rail is paid, damping block is a discontiguous planar slide guide rail, it and moving component fix, its with surface that the steel flat guide cooperates on post wear-resisting guide-soft-band, join work and form 0.02～0.03mm gap with the steel flat guide, and on damping block, being drilled with oilhole, the injection of oil makes between steel flat guide and the damping block and forms squeeze film.
First effect of the straight-line rolling damping vibration attenuation guide rail that is equipped with damping block and constitutes between the roller slide block that guide rail is paid is that tangible damping effect is arranged, because 0.02～0.03mm oil film that damping block and steel guide rail surface form can play the effect of a squeeze film shock absorber, can reach the favorable damping effect; And, can produce capillarity because the oil film of this layer 0.03mm is very thin, so oil consumption is seldom, only needs timing in oilhole, to splash into and get final product.Another effect of using straight-line rolling damping vibration attenuation guide rail is to restrain the plastic deformation that bump produces, because only there is the gap of 0.02～0.03mm on damping block and steel guide rail surface, after being impacted, the rolling element that is adjacent deflection to arrive this numerical value, and therefore this deflection value reduces mechanism and damages within the rolling element regime of elastic deformation.Additional advantage of the present utility model is a highly versatile, is applicable to each sharp putting down and guide rail, and manufacturing is simple, and economically feasible is convenient to apply in machine industry.

The specific embodiment
By shown in Figure 1, straight-line rolling damping vibration attenuation guide rail, it comprises that steel guide rail 1 forms guide rails with several roller slide blocks 2 and pay, between the roller slide block 2 that guide rail is paid, be equipped with damping block 3, damping block is a discontiguous planar slide guide rail, can adopt steel or cast iron to make matrix, it and moving component 6 fix, in the present embodiment, moving component 6 is a machine tool dragging plate, damping block 3 is fixing with screw 5 with machine tool dragging plate, its with surface that the steel flat guide cooperates on post wear-resisting guide-soft-band, guide-soft-band adopts TURCITE soft strip material or other wear-resisting soft band, joins with the steel flat guide and does and form 0.02～0.03mm gap 7, and being drilled with oil filler point 4, the injection of oil makes between steel flat guide and the damping block and forms squeeze film.Steel guide rail 1 shown in Figure 1 is the rectangle steel guide rail, and it also can be San shape guide rail, circular guideway, " V " font guide rail etc., the damping block of the configurable respective shapes of these guide rails, as shown in Figure 2 be the damping block of " V " font guide rail and respective shapes.
