On guide rail, which includes grating scale, grating measuring apparatus, processor, lower skateboard, the lead screw connecting with lower skateboard and servo electricity
Machine, the front end of the lower skateboard are equipped with the grinding carriage of corresponding grinding wheel mechanism, and being equipped with above lower skateboard can swing in certain amplitude
Fixing lug boss, the fixing lug boss is equipped with guide wheel mechanism；Processor respectively with grating measuring apparatus and servo motor communication link
It connects.
The grating scale is also known as grating rule displacement sensor, is the dress that feedback is measured using grating optical principle
It sets, is usually used in the position detection of lathe straight-line displacement.After the grating measuring apparatus is mounted on grinding mechanism, can be to grinding after
On-line Product real-time measurement size.
Further, the fixing lug boss is set there are two the kidney slot with certain radian, and lower skateboard is equipped with vertical point
Not Cha Ru two kidney slots positioning pin.Lower skateboard is generally rectangular cross-section, and fixing lug boss can be in certain amplitude relative to lower skateboard
It swings, the straight line including horizontal direction is swung, rotation, or the combination for swinging and rotating.
As advanced optimizing for the utility model, fixing lug boss can rotate within a certain angle relative to lower skateboard.Institute
Camber line where stating two kidney slots corresponds to the identical center of circle.
Further, the lower skateboard lower surface is equipped with sliding slot, and grinding machine is equipped with the incision guide rail cooperated with sliding slot.In order to
Guarantee certain transmission accuracy and stationarity, minimize frictional force, servo motor and lead screw select high-precision ball-screw
Pair of nut.Servo motor is equipped with encoder and Nd-Fe-B permanent magnet material.
Further, the fixing lug boss is equipped with the fin with guide wheel mechanism limit cooperation, keeps guide wheel mechanism and fixation convex
Platform is closely linked.
Guide rail is the double triangle guide rail of bilateral symmetry formula, can compensate abrasion loss automatically, and sideshake can compensate automatically,
It is adjusted without panel.To guarantee certain guiding performance, while frictional force is reduced, the apex angle of triangular guide rail is 90 ~ 100 °
For the frictional force for reducing bottom guide track, the contact surface of the guide rail and sliding slot is equipped with made of polytetrafluoroethylene material
Buffer layer.
The utility model has the advantages that the utility model is based on grating measuring apparatus measurement converted products size after processor is handled, pass through
Servo motor drives the feeding of wheel frame, compensates the amount of feeding, eliminates mismachining tolerance, forms closed-loop control.The device it is swingable
Fixing lug boss meets the requirement of different grinding entrance angles, and Guide Rail Design is stablized accurately, guarantees the long-term operation of grinding machine.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the assembling schematic diagram of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of coreless grinding machine autocompensation installation is set on guideway of grinding machine 1, which includes gliding
Plate 2, fixing lug boss 3, grinding carriage 4, introduction mechanism 5, lead screw 6, feed screw nut 7, servo motor 8, grating scale 9, grating measuring apparatus
14 and processor.
Grinding machine incision guide rail 1 is the two groups of convex ridge structures for being divided into 6 two sides of lead screw and extending along feedstock direction, apex angle 90
~100°.Lower skateboard 2 is rectangular plate, is equipped with sliding slot 10 compatible with its ridge-shape, and cross sectional shape is M shape.Lower skateboard
2 lower performances are fixed with feed screw nut 7, match with lead screw 6, move back and forth under the transmission of servo motor 8 along feed direction.Servo
Motor 8 is connect with processor communication.Servo motor is equipped with encoder 15 and Nd-Fe-B permanent magnet material.
The front end of lower skateboard 2 is equipped with grinding carriage assembled plate 11, for installing the grinding carriage 4 of corresponding grinding wheel mechanism.Lower skateboard 2
Top is equipped with the fixing lug boss 3 that can be swung in certain amplitude, and fixing lug boss 3 is equipped with introduction mechanism 5.Grating scale 9 is set to down
2 side of slide plate, connect with processor communication, can be to the product after grinding after grating measuring apparatus 14 is mounted on grinding mechanism
On-line sampling system size.Grating scale is measured to the actual location of measured axis, and positioning can be quickly obtained by handling through software
Error curve and position precision data (i.e. the shift position positioning of fixing lug boss).
The working principle of grating scale and its measuring instrument is: interference mirror is fixed on spindle end, and main spindle's is kept to fix, and swashs
The distance of light device and interference mirror is fixed, and reflecting mirror is fixed on the table, with movable workbench.Laser emitter is by occurring light
It is reflected through reflecting mirror, by measuring since operating position changes the interference fringe number that reflected light generates, inside laser
Processing circuit carries out processing measuring and calculating to striped, obtains position error curve data.
Fixing lug boss 3 is set there are two the kidney slot with certain radian, and lower skateboard 2 is equipped with vertical two waists of insertion respectively
The positioning pin 12 of shape slot.Fixing lug boss 3 can be rotated relative to lower skateboard 2 in certain amplitude.Camber line where two kidney slots
The corresponding identical center of circle.Fixing lug boss 3 is equipped with the fin 13 that cooperation is limited with introduction mechanism 5, makes introduction mechanism 5 and fixing lug boss
3 are closely linked.For the frictional force for reducing bottom guide track 1, the contact surface of guide rail 1 and sliding slot 10 is equipped with polytetrafluoroethylene (PTFE) material
Buffer layer made of expecting.
The standard size of workpiece after having set processing is preset in computer processor, i.e. the diameter tolerance of bar allows model
It encloses, the discharging region of centerless grinding machine is mounted with the grating measuring apparatus for measuring diameter of rod.In the process of centerless grinding machine work
In, workpiece to be processed passes through wheel grinding first, and horse back workpiece enters grating measuring apparatus after being ground, and is surveyed by grating measuring apparatus
Diameter after its processing out, signal is sent into computer processor by the diameter data measured, if grinding wheel or guide wheel produce mill
Damage, then the diameter of workpiece has small increase, then the data measured are just and oneself data that are set produce deviation, at this time
Signal is issued from computer processor to servo motor, by servo motor driving wheel frame feeding, makes guide wheel, bracket is to grinding wheel position
It is mobile, restore reasonable grinding gap again.To make up abrasion of grinding wheel bring outer diameter deviation.The essence of guide wheel workbench
Really grating scale is located through to be positioned.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
