Description

A kind of high accuracy line slideway special purpose grinder
Technical field
The present invention relates to digit ctrol machine tool field, more particularly to a kind of high accuracy line slideway special purpose grinder.
Background technology
Line slideway special purpose grinder generally carries out finishing grinding to workpiece using emery wheel, and the finishing of emery wheel is using shaping gold Firm pair of rollers emery wheel is repaired, and installs direct dimensional accuracy, the morpheme to product of site error of emery wheel burring machine Error, roughness produce influence.Existing emery wheel burring machine has two kinds of frame modes:
1) emery wheel burring machine is installed on the table, and positioning finishing emery wheel is carried out using movable workbench, in order to Positioning precision is reached generally using fro hydraulic driving machinery positioning and lead screw transmission servo-positioning, and fro hydraulic driving machinery positioning is taken Between the defect such as long, positioning precision is poor;Lead screw transmission servo-positioning machine tool movement speed is slow, leading screw quick abrasion.
2) emery wheel burring machine is arranged on double bistrique both sides, and install trimmer in double bistrique both sides does not have to dimensional accuracy Secure, the finishing inner side grinding of emery wheel outside cannot ensure product space error.
And, existing guide rail is moved using line slideway, and transverse shifting guide rail is now with two kinds of mobile forms:
1) line slideway movement
Frictional force when line slideway movement solves mobile, improves feed accuracy, but produced when lathe is ground Vibrations cannot effectively discharge, easily produce resonance during grinding, make grinding workpiece surface produce shake line, influence surface essence Degree.
2) rectangular slide guide rail movement
This guide rail movement can solve the discharge of grinding vibrations, but frictional force is very big when mobile, and upper rail lower guideway rubs It is when wiping that power is different to make machine tool feed asynchronous up and down, it is ensured that not feed accuracy.
The lathe of both the above structure all cannot accomplish error free autogenous grinding, it is necessary to be ground using frock is installed additional to workpiece mounting surface Head is ground, and is taken a lot of work, is not reached required precision arduously.
In sum, the frictional force of existing high accuracy line slideway special purpose grinder is big, damping effect is bad, it is impossible to ensure Product Precision, low precision, defect rate is high, reduces operating efficiency.
The content of the invention
The invention aims to provide a kind of high accuracy line slideway special purpose grinder, make its degree of accuracy high, damping effect It is good, high working efficiency, low cost.
To solve the above problems, the present invention provides a kind of high accuracy line slideway special purpose grinder, including lathe bed, workbench, Magnechuck, emery wheel, bistrique, roll dresser main shaft, roll dresser and KK modules, described lathe bed are provided with workbench, Magnechuck is installed, grinding work piece is fixed on magnechuck on workbench, crossbeam is additionally provided with lathe bed, be provided with crossbeam Mounting seat, center is provided with KK modules in mounting seat, and bistrique slide plate is provided with crossbeam, and vertical cunning is provided with bistrique slide plate Pillow, is installed with bistrique and motor on vertical ram, the lower end of bistrique is provided with emery wheel, and the centre of two bistriques is provided with roller Trimmer main shaft, the lower end of roll dresser main shaft is provided with roll dresser.
Further, described crossbeam upper end is provided with steel guide rail two and rolling guide block, and the upper end of bistrique slide plate is fixed with Pressing plate, steel guide rail two and rolling guide block are located between pressing plate and crossbeam, by pressing plate and rolling between bistrique slide plate and crossbeam Way block is connected, and steel guide rail one is provided between the horizontal plane of the lower end of bistrique slide plate and crossbeam, and steel guide rail one is provided with rolling and leads Rail block.
After such design, the present invention at least has advantages below:
Realize that Installing machine tool surface is ground by roll dresser main shaft itself, the design of double abrasive wheel can be carried out to work side Repair simultaneously, it is ensured that workpiece mounting table face is vertical with roll dresser main shaft, while ensure that double abrasive wheel grinding same contour On position, solve the contour error of transverse direction when existing lathe is ground, the degree of accuracy is high, at the same can improve operating efficiency 30% with On.
The reduction of machine tool movement coefficient of friction can be made using this technology, it is ensured that mobile steady, feeding is accurate, is capable of achieving feeding Rate 0.001mm, being combined with glass hard steel guide rail using roller scroll box can make machine tool accuracy keep longer, while being led using slip The transmission vibrations of rail faying face can make grinding quality higher.
