Abstract
The invention discloses a vibration signal-based automatic tool setting device for a full-automatic motor rotor balance calibrating machine. A motor rotor is fixed on a baseplate through a fixture, a cutting tool is arranged on a rotating spindle of a cutting head and is driven by a moving workbench fixed on the base plate, and a vibration acceleration sensor is fixed on a shell of the cutting head and is connected with a signal processing circuit through a vibration signal transducer. During work, the moving workbench drives the cutting head and further drives the cutting tool to feed to the motor rotor vertically, and when the cutting tool contacts the motor rotor, cutting force is generated instantly. Because the cutting force is alternating, the cutting head is vibrated, the vibration acceleration sensor senses the vibration, and the output vibration signal is processed by the vibration signal transducer and the signal processing circuit to form a tool setting signal. An insulating board is eliminated to avoid breakover interference of cut scrap iron; and the device is suitable for a full working condition period, can adapt to continuous automatic production, and reduces requirements on maintenance and machine adjustment.
Description
Technical field
The present invention relates to the device of automatic tool preset, especially relate to the full-automatic balance straightener of a kind of rotor automatic tool preset device based on vibration signal.
Background technology
Motor is important production and daily necessities, and rotor wherein is the important process parts of motor., reasons such as shape asymmetric, process and assemble error inhomogeneous owing to material, the rotor of harsh output exists amount of unbalance inevitably.In the operation process of motor, the dynamic loading that amount of unbalance produces will act on stationary parts, thereby cause vibration, noise and properties of product degeneration.Therefore must carry out dynamic balancing to rotor.
Rotor dynamic balancing calibration equipment in the production can be divided into two big classes, promptly manual rotor dynamic balancing machine and the full-automatic rotor dynamic balancing machine proofreaied and correct.Manual correction dynamic balancing machine cost is low, but its production efficiency is low, equilibrium process relies on workman's experience, general balance quality is not high, and its cutting quantity to rotor is more, cause the rotor electric property to weaken easily motor performance is degenerated, so be difficult to satisfy the production needs of the rotor of high-efficiency high-quality.In contrast to this, full-automatic rotor dynamic balancing machine production efficiency height, the balance quality height can carry out quality optimization to the rotor cutting, but the machine price is more expensive relatively.Along with the development of China's motor industry, adopt full-automatic rotor dynamic balancing machine to become inexorable trend at present.
Full-automatic rotor dynamic balancing machine in working angles, the problem of cutting tool that key issue is cutting tool and rotor that solve.Particularly, when the rotor cutting goes to weigh, judge cutting tool and rotor position contacting first exactly, i.e. tool setting point, and as reference point, thereby control cutting tool amount of feeding control cutting quality.Therefore tool setting point determines that cutting precision is had fundamental influence.
For general machining apparatus, as lathe and milling machine etc., what adopt usually is that the trial cut method is determined the tool setting point.Promptly under the manual method of operation, slowly travelling table, and the situation that contacts of observing cutting tool and workpiece, wait to find have iron filings to fly out, and can hear after the sound, think that then cutter has contacted with workpiece, write down this point as tool setting point or processing basic point, carry out follow-up processing.This mode can't realize in enormous quantities and high-precision production because the existence of artifact can't realize automation, and repeatable accuracy is lower.For Digit Control Machine Tool and automatically processing device, what adopt usually is acquiescence tool setting point.Promptly, get one of them and carry out artificial tool setting, find the tool setting point same batch workpiece, later on all workpiece all with this tool setting point as datum mark.Because the wearing and tearing of the influence of form and position tolerance own and out-of-roundness or anchor clamps all can make actual tool setting point depart from this acquiescence tool setting point between the workpiece, so adopt acquiescence can't guarantee cutting precision to cutter mechanism.
" a kind of full-automatic balancing machine automatic positioning equipment " of Chinese patent ZL200720113068.9 proposed insulation board and separated cutter (together with the base of tool) and rotor, and utilizes both to contact the method that conduction is judged tool setting point.This method is simple and practical, but in actual applications, and the iron filings that cut can be attached on the insulation board and occur misleading, and need clear up iron filings termly, and this can interrupt the continuity of work and lower efficiency.Document " research of heavy system and key technology thereof is gone in the dynamic balancing numerical control ", " electromechanical engineering " 2005 22 volumes 5 phase 4-8 pages or leaves, the method that provides is to utilize bearing to rotate the formed oil film electric capacity in back, adopts the driving voltage of high frequency to measure changes in capacitance, and judges the tool setting point of cutter with this.Owing to adopt high-frequency excitation signal, introduced High-frequency Interference simultaneously, influenced the reliability of signal.In addition, when just bringing into use, bearing, after the break-in of using longer a period of time, just enters stable working condition because there is the phenomenon that misleads equally in the microcosmic out-of-flatness on surface.Chinese patent 200920295380 has provided the method that a kind of dynamic oil film that utilizes bearing carries out tool setting.The shortcoming of this method is to be the clean grease of bearing replacing termly, uses inconvenient.
Summary of the invention
The object of the present invention is to provide the full-automatic balance straightener of a kind of rotor automatic tool preset device based on vibration signal, be for the full-automatic balance straightener of rotor provide do not cut in a kind of accurate positioning, simple in structure, the course of work that iron filings disturb can operation steady in a long-term the device of automatic tool preset
