Description
Technical field
The utility model relates to the regulation and control of grinding accuracy, especially a kind of precision monitoring of centerless grinder.
Background technology
Existing centerless grinder such as MT1040, MT1020 etc., its machining accuracy is 0.002mm under normal running conditions (friction, wearing and tearing etc.), simultaneously its guide wheel has-1～3 ℃ angle of revolution in horizontal plane, but therefore trimming wheel or the guide wheel workpiece of grinding certain taper scope just not.Abrasive dust enters the feed mechanism guide rail or other reasons has produced wearing and tearing or wheel frame vibration but work as, the capital causes mechanical type feed mechanism dial amount of feeding sign value and actual grinding volume production to give birth to difference, thereby grinding accuracy can not accurately be controlled, and the converted products qualification rate descends.
The utility model content
The purpose of this utility model provides a kind of precision supervising device of centerless grinder, realize the direct monitoring of the centerless grinder feed mechanism amount of feeding, the amount of feeding that operation is regulated can reflect actual grinding amount exactly, guarantee grinding accuracy, can realize indirect control and supervision simultaneously the vibration of centerless grinder wheel frame.
Centerless grinder precision supervising device of the present utility model comprises that signals collecting and processing, result show two parts.Signals collecting and processing section are made up of contact orthoscopic displacement transducer, sectional fixture, index dial and the L bracket of falling; Sensor passes the horizontal through hole of sectional fixture, and is fixedly clamped by it, and the vertical axis of sectional fixture bottom is mounted in the centre bore of index dial, and sectional fixture can turn round in this centre bore, drives sensor simultaneously and turns round in horizontal plane; Index dial is installed on two parallel slots parallel with the direction of feed of feed mechanism of grinding machine of the horizontal component of falling the L bracket by screw, can move along parallel slot in the horizontal direction; The vertical component of L bracket of falling is fastened on the grinder bed end face with the feeding structure homonymy with screw.Tangent displacement sensor contact plane remains face with the guide rail end surface of feed mechanism of grinding machine and contacts, it is linked in sequence by contact grating chi, differential amplifier circuit, shaping circuit and frequency multiplication segmentation gate circuit and forms, with the horizontal signal of feed mechanism of grinding machine change into the signal of telecommunication and through amplify and handle after the input results display part.The display part is made up of forward-backward counter and digital display as a result, directly shows the amount of feeding of feed mechanism.
Because contact linear displacement transducer of the present utility model can move horizontally in the direction of feed of feed mechanism, can turn round at horizontal plane by sectional fixture again, and keep identical angle of revolution with the wheel frame of grinding machine, therefore the contact that can guarantee sensor remains face with the guide rail end surface of feed mechanism and contacts, realized the direct demonstration of the amount of feeding on digital display device of feed mechanism, can directly regulate the amount of feeding of feed mechanism according to this show value, improve transmission accuracy, realize accurately location, thereby the amount of feeding that has overcome the feed mechanism dial that existing centerless grinder may exist is regulated sign value and the defective that actual grinding amount is not inconsistent, and makes the grinding accuracy all-the-time stable be controlled at 0.002mm; Unstable if digital display device shows numeral in addition, reflect that then the grinding machine wheel frame has vibration, can eliminate vibration by searching reason, thereby can realize the indirect control and supervision of wheel frame vibration is beneficial to and guarantees grinding accuracy.
The utility model apparatus structure is simply compact simultaneously, and cost is lower, and the monitoring amount of feeding is intuitively quick, and monitor data is reliable and stable.Improve slightly, also can be used for the precision monitoring of other grinding machines.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The precision supervising device of centerless grinder MT1040A comprises that signals collecting and processing, result show two parts.Signals collecting and processing section are made up of contact orthoscopic displacement transducer 1, sectional fixture 15, index dial 2 and the L bracket 3 of falling.Sensor 1 passes the horizontal through hole of sectional fixture 15, and it is clamped fixing, the vertical axis 17 of sectional fixture 15 bottoms is installed in the centre bore of index dial 2, adjust sectional fixture 15 in horizontal plane the angle of revolution and the angle of revolution of grinding machine wheel frame 19 in full accord after, with holding screw 16 sectional fixture 16 is fastened in the centre bore of index dial 2.Index dial 2 is installed in down in two parallel slots 5 of L bracket 3 horizontal components by 4 screws 4, parallel slot 5 is parallel with the direction of feed of feed mechanism of grinding machine 7, move horizontally index dial 2, make the contact plane of sensor 1 be adjacent to the guide rail end surface 8 of feed mechanism, and after compacted, lock 4 screws 4.The vertical component of L bracket 3 of falling then is fixed on the grinder bed end face 18 with feeding grinder structure 7 homonymies by screw 6.
Sensor 1 is linked in sequence and is formed by contact grating chi 9, differential amplifier circuit 10, shaping circuit 11, frequency multiplication segmentation gate circuit 12.Because sensor 1 can be with index dial 2-5 °～+ 5 ° of horizontal plane revolutions, can move with the direction of feed of index dial 2 simultaneously at feed mechanism 7, so when adjusting the amount of feeding, and in Grinding Process, the contact plane that can guarantee sensor 1 remains face with the guide rail end surface 8 of feed mechanism 7 and contacts, thereby realizes the reliable and stable monitoring to feed mechanism 7 amount of feeding.
The display part is made of forward-backward counter 13 and D80 digital display device 14 as a result, and both can be used as integrative-structure.
During the work of the utility model device, by contact grating chi 9 the feed mechanism of grinding machine horizontal displacement signal of accepting is converted into the signal of telecommunication, after differential amplifier circuit 10 amplifies, change square-wave signal into by shaping circuit 11, input forward-backward counter 13 carries out step-by-step counting after being changed into burst pulse and carried out the frequency multiplication segmentation by frequency multiplication segmentation gate circuit 12 again, and directly show the amount of feeding of feed mechanism 7 by digital display device 14, the operator then directly regulates feed mechanism 7 according to show value, eliminate driving error, realize accurately location, thereby reach the accurate control of converted products size.
Through the grinding experiment and the production of hard alloy bar, the grinding accuracy all-the-time stable of workpiece is at 0.002mm, and product percent of pass has improved 12%, reaches more than 95%.
The demonstration of digital display device 14 numeral is eliminated vibration by searching reason, thereby can be realized the indirect control and supervision of wheel frame vibration if occur beating, when unstable, reflect that then the grinding machine wheel frame has vibration, improves the stability of grinding accuracy.
