Description
Technical field
The present invention relates to a kind of match grinding method, particularly automatic locating and grinding method for general cylindrical grinding machine.
Background technology
The rolling guide pillar of rotating shaft and bearing, valve and valve body, mould etc. all is a mating part, and its gap or interference are to be obtained by the match grinding processing that datum hole is joined axle.
Known trial cut match grinding method is measured the actual size in each aperture earlier before match grinding, with same size grouping, numbering, tabulation, by the fiting property requirement, with trial cut method repeatedly spouse's diameter of axle is milled to ideal dimensions, the shortcoming of this method be processing with measure extremely loaded down with trivial details, the location is inaccurate, easily goes out waste product.
The match grinding that document " " PMKZ-2 match grinding with initiatively measuring and controlling " specification " discloses 55 research institutes of Ministry of ordnance Industry is with measuring and controlling initiatively, this device adds a cover by hole measuring device on automatic or semi-automatic grinding machine, survey shaft device, " match grinding is the measuring and controlling initiatively " that controller is formed, to survey accurate aperture size signal by hole measuring device earlier and be defeated by controller, in grinding process, survey shaft device and also diameter of axle change in size signal is defeated by controller, two signals compare, when reaching predefined fiting property, just send and stop emery wheel feeding signal, the inductance sensor that hole measuring device is close with surveying each free two performance of shaft device is formed, the match grinding size is limited to endoporus Φ 4～Φ 40mm, hole depth 2～40mm scope.The deficiency that this device exists is: the size-constrained system of match grinding; Need the OLRT gaging hole footpath and the diameter of axle, adjust cumbersome; And the flexibility that grinding machine encloses the cloth hole measuring device, surveys shaft device, controller must reduce grinding machine, be unfavorable for that medium or small factory adopts.
Summary of the invention
In order to overcome the size-constrained system of prior art match grinding, the deficiency that needs the OLRT gaging hole footpath and the diameter of axle and reduce the grinding machine flexibility the invention provides a kind of automatic locating and grinding method for general cylindrical grinding machine, can realize same size aperture grouping location match grinding automatically.
The present invention solves the technical scheme that its technical problem takes: a kind of automatic locating and grinding method for general cylindrical grinding machine, it is characterized in that, and comprise the steps:
1) adjustable push rod 6 is fixed on the pivoted arm 5, pivoted arm 5 is connected with support 4 by hinge, support 4 is fixed on the grinding carriage 3, with adjustable push rod 6 and sensor 9 gauge head centerings, sensor 9 is fixed on the lathe bed, and primary coil is electrically connected with multivibrator 8, and secondary coil is electrically connected with differential rectifier 10, after power interface 12 and cylindrical grinder are carried out electrical equipment KM and fast backward button SB and be electrically connected, pass through K switch

The circuit diagram of Fig. 2 automatic locating and grinding method for general cylindrical grinding machine of the present invention
Among the figure: 1-workpiece, 2-emery wheel, 3-grinding carriage, 4-support, 5-pivoted arm, the adjustable push rod of 6-, 7-dc source, 8-multivibrator, 9-sensor, 10-differential rectifier, 11-digital panel meter, 12-power interface.
The specific embodiment
With reference to Fig. 1～2, the present invention is made up of dynamo-electric two parts, and mechanical part comprises support 4, pivoted arm 5 and adjustable push rod 6; Control device comprises dc source 7, multivibrator 8, sensor 9, differential rectifier 10, digital panel meter 11 and power interface 12.Support 4 is fixed on the grinding carriage 3, pivoted arm 5 is connected with support 4 by hinge, adjustable push rod 6 is the micrometer heads that scale value is 0.01mm, it is fixed on the pivoted arm 5, be used to change the adjusting of processing diameter, support 4, pivoted arm 5, adjustable push rod 6 and sensor 9 gauge head centerings, the grinding carriage 3 that tightens up after mixing up with feeding moves.Sensor 9 is fixed on the lathe bed, and is constant, and its primary coil is electrically connected with multivibrator 8, and secondary coil is electrically connected with differential rectifier 10.When grinding carriage 3 feedings, push rod 6 touches the gauge head of sensor 9, moves it the electromagnetic induction signal variation takes place, and through differential rectifier 10 voltage signal is delivered to digital panel meter 11, demonstrates grinding carriage 3 residing position and variations thereof.All be defined as zero as cutting endpoint signal with any basic size workpiece, and drive pin PM by the A/D7107 negative polarity of digital panel meter 11 and send signal, when the demonstration number that digital panel meter 11 occurs when grinding carriage 3 feedings, sensor 9 gauge head displacements is zero, the A/D7107 negative polarity of digital panel meter 11 drives pin PM and just sends automatic location withdrawing signal, drives lathe execution electrical equipment KM by power interface 12 and finishes the automatic withdrawal action.
It is ± 1mm to be the not differential transformer of the distinguishable 0.1 μ m of displacement enlargement signal that the stroke of sensor 9 is calculated from symmetrical centre.
By ZL
1The dc source 7 of rectification is supplied with multivibrator 8 through integrated regulator 7909 voltage stabilizing one-tenth-9V earlier, supplies with digital panel meter 11 through integrated regulator 7905 voltage stabilizing one-tenth-5V again.Multivibrator 8 produces the approximate square wave of about 2000Hz, the primary coil that offers sensor 9 is excitatory, and the pulsation induced voltage that its twice levels produce becomes direct current differential voltage signal through differential rectifier 10, directly supply with digital panel meter 11, show that the displacement of sensor 9 changes.
The automatic location of cutting terminal point and withdrawing drive pin PM control by the A/D7107 negative polarity of digital panel meter 11, and its effect is that switched voltage polarity is crossed " 0 " change "-" or its opposite process by "+", with
1/
2Position light emitting diode g stroke is electrically connected, and drives pin PM from the A/D7107 negative polarity and draws a branch road in addition, and light emitting diode and power interface 12 couplings by photoisolator MOC3081 make its promotion lathe carry out electrical equipment KM and realize the automatic withdrawal action.The A/D7107 negative polarity drives pin PM and is controlled by logic level, appears at the zero crossing of polarity transformation, only " 0
+" to " 0
-" or its inverse process switching; Because chip A/D7107 inside is provided with the auto-zero circuit, zero drift error is very little, can be little with its resetting error of raising of resolving power to ± 0.1 μ m, be better than the voltage comparator positioning performance.
The iron core of sensor 9 has a unlimited continuous equilbrium position, and it is masked as the input voltage V of digitizing tablet 11
In=0, can be with its framing signal as the cutting terminal point, the switching that drives pin PM by the A/D7107 negative polarity realizes location and withdrawing function automatically.The potentiometer W of aforementioned equilbrium position and differential rectifier 10
