Description
Technical field
The utility model relates to Control System Design field, especially relates to a kind of machine vibration online monitoring system.
Background technology
The vibration that lathe produces in process, not only can affect lathe dynamic accuracy and part to be processed quality, but also production efficiency and tool life will be reduced, even lathe usability can be reduced when vibrating violent, can affect the health of machine operators with vibrating the noise sent, machine vibration is divided into forced vibration and autovibration.On lathe, milling machine and grinding machine, vibration is passed to lathe by ground by vibration source, turns round the forced vibration that the mass unbalance of parts, the foozle of driving member and cutting vibration all can cause lathe simultaneously.The autovibration type that lathe occurs is more, such as there are the torsion of rotary main shaft (or contacting with workpiece or with cutter) system or bending autovibration, the support members such as bed piece, column, crossbeam bending or rock autovibration, relaxation friction self-excited vibration (common name is creeped) also having the moving-members such as worktable to occur when slow running etc.
Machine vibration not only causes geometric configuration and the scale error of workpiece, but also chatter mark will be left on machined surface, reduce workpiece accuracy and surface smoothness, the chill situation of aggravation matallic surface layer, during vibration, cutting wear also will sharply decline, blade is even caused to crumble, this is concerning particularly serious the more crisp carbide-tipped tool of character and pottery money cutter, after lathe vibrates, operator is often forced to reduce cutting data, thus reduce the throughput rate of lathe, economic benefit also can be had a strong impact on simultaneously.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and the machine vibration online monitoring system that a kind of structure is simple, easy to operate, fiduciary level is high is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of machine vibration online monitoring system, comprise controller, touch-screen, warning horn, printing equipment, lathe main frame, spindle drive motor, signal pickup assembly, bearing seat acceleration transducer, fixture acceleration transducer, workholder and main shaft rolling bearing, described printing equipment is connected with controller respectively with signal pickup assembly, described warning horn is connected with controller by touch-screen, described spindle drive motor is connected with controller by lathe main frame, described workholder is connected with signal pickup assembly by fixture acceleration transducer, described bearing seat acceleration transducer is connected with signal pickup assembly by main shaft rolling bearing.
Described signal pickup assembly comprises the signal picker, filter amplifier and the A/D converter that connect successively, and described signal picker is connected with fixture acceleration transducer and bearing seat acceleration transducer respectively, and described A/D converter is connected with controller.
Described controller is programmable logic controller (PLC).
Described warning horn comprises hummer and warning light.。
Compared with prior art, the utility model has the following advantages:
1, structure is simple, manufactures easy maintenance;
2, automaticity is high, adopts PLC programming Control, saves human resources, increases work efficiency;
3, flexible strong, the requirement of the part processing different accuracy is adapted to by programming change warning variate-value;
4, reliability is high, both take into account the autovibration larger on main shaft impact, has contemplated the impact of external vibration on workholder, prevent the uncertainty of single vibration, improve product qualified rate.
