Description

A kind of linear guide isothermal normalizing heating furnace
Technical field
The present invention relates to a kind of linear guide isothermal normalizing heating furnaces.
Background technique
Linear guide is also known as line rail, sliding rail, linear guides, linear slide rail, is used for straight reciprocating motion occasion, and can hold Certain torque is carried on a shoulder pole, can realize high-precision linear motion in high-load situations, this.Depending on frictional property, linear motion Guide rail can be divided into the types such as sliding friction guide rail, rolling friction guide rail, elastic-friction guide rail, fluid friction guide rail.Linear axis Hold be used primarily on automated machine compare it is more, as the lathe of German import, bending machine, laser-beam welding machine etc., certain straight line Bearing and linear axis are matched.As linear guide mainly in the relatively high mechanical structure of required precision, straight line is led Do not have to intermediate medium between the moving element and fixing element of rail, and uses rolling steel balls.
Sliding block-makes movement by profile changeover straight line.Guide track system makes lathe can get fast feed speed, turns in main shaft In the identical situation of speed, the characteristics of fast feed is linear guide.For linear guide as flat guide, there are two substantially first Part;One is fixing element as guiding, the other is moving element.Since linear guide is standarized component, to lathe system Make the depth of parallelism of the plane for only processing an installation guide rail and tune-up guide rail that for factory uniquely to be done.Certainly, in order to guarantee The precision of lathe, lathe bed or a small amount of scraping of column be it is essential, in most cases, installation is fairly simple.Make Guide rail for guiding is hardened steel, is placed on mounting plane through fine grinding.Compared with flat guide, linear guide cross section it is several What shape, more complicated than flat guide, complicated reason is because needing to process groove on guide rail, in favor of the shifting of sliding members It is dynamic, the shape and quantity of groove, depending on the function to be completed of lathe.Such as: one had not only been born linear function power, but also has born top The guide track system for covering torque is very different in design compared with the guide rail for being subjected only to linear function power.
The basic function of the fixing element (guide rail) of linear rail system installs the bracket of steel ball, shape such as bearer ring For " v " font.Bracket is wrapped in the top and two sides of guide rail.In order to support the workpiece of lathe, a set of linear guide is extremely It is few that there are four brackets.It is used to support large-scale workpiece, the quantity of bracket can be more than four.
When the workpiece of lathe is mobile, steel ball is just circulated in bracket groove, and the abrasion loss of bracket is shared On each steel ball, to extend the service life of linear guide.In order to eliminate the gap between bracket and guide rail, preload energy The stability of guide track system is improved, the acquisition of preloading is that overdimensioned steel ball is installed between guide rail and bracket.Steel ball is straight Diameter tolerance be ± 20 microns, with 0.5 micron for increment, steel ball sifting sort is respectively pivoted on guide rail, preload it is big It is small, depending on acting on the active force on steel ball.If the active force acted on steel ball is excessive, it is subjected to preloading time mistake It is long, cause support motion resistance to enhance, with regard to will appear balanced action problem;In order to improve the sensitivity of system, movement resistance is reduced Power will correspondingly reduce preloading, and in order to improve the retentivity of kinematic accuracy and precision, it is desirable that there are enough pre-add negative Number, this is contradictory two aspect.
Working time is too long, and steel ball is begun to wear out, and the preload acted on steel ball starts to weaken, and lathe is caused to work The reduction of component kinematic accuracy.If keeping initial precision, it is necessary to replace rail brackets, or even replacement guide rail.If guide rail System has preload effect.System accuracy has been lost, and unique method is replacement rolling element.
The design of guide track system makes every effort to have maximum contact area between fixing element and moving element, this can not only be mentioned The bearing capacity of high system, and system can bear intermittent cut or gravity impact force caused by cutting, and active force is expanded extensively It dissipates, expands the area of endurance.To achieve it, the groove shape of guide track system is there are many multiplicity, it is representative There are two types of, a kind of referred to as Gothic (gothic arch), shape is the extension of semicircle, and contact point is vertex;Another kind be it is arc-shaped, together Sample can serve identical.
It in the processing technology to linear guide raw material, needs to be heat-treated material, heat treatment generally includes to add Heat, heat preservation, cooling three processes.Wherein, heating temperature is different with processed metal material and heat treatment purpose, but heats Purpose typically to make prevent can undergo phase transition.Since tissue inter-variable needs certain process, it is heated to material It after predetermined temperature, needs to be kept for the temperature regular hour, phase transformations is waited to carry out cooling treatment again after the completion;Cooling control also ten Point important, cooling velocity often will affect the hardness of material.
