The present invention relates to the Machine Tools Electric automation control system, is a kind of surface grinding machine digital control system with concavo-convex grinding function specifically.
(2) background technology:
When workpiece such as machine tool guideway, grinding tool being carried out grinding with surface grinding machine, usually need on the basis of flat surface grinding, carry out vertical concave-convex curved surface grinding of trace, way is traditionally, the lengthwise movement of numerical control plane Grinder bench and the vertical feed of emery wheel are moved by the numerical control axle and are driven control, to realize described concave-convex curved surface grinding.
But present surface grinding machine, though especially the feeding of Large Plane Grinder emery wheel is the numerical control axle, promote by oil cylinder by hydraulic system but the length travel of workbench is many, but not pass through motor-driven, therefore the grinding machine digital control system can't realize the concave-convex curved surface grinding owing to can't judge vertical Working position that workpiece is current on the longitudinal grinding direction of workpiece.
(3) summary of the invention:
The invention provides a kind of surface grinding machine digital control system that realizes the vertical concavo-convex grinding of workpiece with concavo-convex grinding function.
Realize the key of vertical concave-convex curved surface grinding on the plane numerical controlled grinding machine of oil cylinder push work platform, be to make the PLC digital control system can detect workpiece (workbench) present located longitudinal grinding Working position and moving direction by induction installation, by the perpendicular grinding amount of feeding of PLC digital control system instruction emery wheel vertical feed driving device controls emery wheel, reach the purpose of the vertical concavo-convex grinding of workpiece again.
Can realize the surface grinding machine digital control system with concavo-convex grinding function of above-mentioned purpose, comprise the PLC numerical control device, by the emery wheel vertical feed drive unit of PLC numerical control device control with by the workbench that vertically moves of hydraulic oil cylinder driving, different is to comprise that also the testing platform vertically moves the induction installation of distance and direction, and described induction installation connects the PLC numerical control device by circuit.
Described induction installation has three kinds of versions:
1, described induction installation is the combination of proximity transducer and tooth bar.
Described tooth bar longitudinally is installed on the workbench, a proximity transducer is installed at least on lathe bed, and the inductive head of each proximity transducer is near tooth bar.
When workbench carries workpiece when doing lengthwise movement, tooth bar lengthwise movement simultaneously, along with tooth root on the tooth bar, tooth top is alternately through proximity transducer, proximity transducer can send pulse signal, this pulse signal has reflected that tooth root or tooth top move through the T/A of proximity transducer, the PLC numerical control device receives this pulse signal, tooth pitch according to tooth bar calculates workbench (workpiece) present located longitudinal grinding Working position and moving direction, send the feeding control signal according to default concave-convex curved surface grinding parameter, control emery wheel vertical feed drive unit is adjusted the perpendicular grinding amount of feeding of emery wheel at any time, thereby realizes the grinding of concave-convex curved surface.
Described tooth bar and proximity transducer can be installed by transposition, can detect the present bit shifting state of workpiece equally, realize the grinding of concave-convex curved surface.
2, described induction installation is the combination of rotary encoder and tooth bar.
Described tooth bar longitudinally is installed on the workbench, and described rotary encoder is installed on the lathe bed, and the wheel and rack in the rotary encoder rotating shaft is meshed.
When workbench carries workpiece when doing lengthwise movement, tooth bar lengthwise movement simultaneously, the driven rotary encoder rotates, make rotary encoder send pulse signal, after the PLC numerical control device receives this pulse signal, calculate workbench (workpiece) present located longitudinal grinding Working position and moving direction according to the tooth pitch of tooth bar and the resolution ratio of rotary encoder, send the feeding control signal according to default concave-convex curved surface grinding parameter, control emery wheel vertical feed drive unit is adjusted the perpendicular grinding amount of feeding of emery wheel at any time, thereby realizes the grinding of concave-convex curved surface.
Described tooth bar and rotary encoder also can be installed by transposition, can detect the present bit shifting state of workpiece equally, realize the grinding of concave-convex curved surface.
3, described induction installation is the backguy encoder, and the pull wire head of backguy encoder is fixed on the workbench, and the backguy encoder is installed on the lathe bed; Or pull wire head is fixed on the lathe bed, and the backguy encoder is installed on the workbench.
Pulse signal is sent in the rotation of pulling rotary encoder during working table movement, after the PLC numerical control device receives this pulse signal, resolution ratio according to rotary encoder calculates workpiece present located longitudinal grinding Working position and moving direction, send the feeding control signal according to default concave-convex curved surface grinding parameter, control emery wheel vertical feed drive unit is adjusted the perpendicular grinding amount of feeding of emery wheel at any time, thereby realizes the grinding of concave-convex curved surface.
Advantage of the present invention:
The present invention has the surface grinding machine digital control system of concavo-convex grinding function by the induction installation of testing platform displacement and direction is set, send pulse signal by induction installation and give the PLC numerical control device, control the emery wheel vertical feed by the concave-convex curved surface grinding parameter that the PLC numerical control device is provided with, thereby on the general NC surface grinding machine of oil cylinder push work platform, realize complicated concave-convex curved surface grinding, can reach the technology acuracy requirement of numerical-controlled grinder special fully, and the present invention is simple in structure, with low cost, stable and reliable for performance, be easy to safeguard.
