Description
Technical field
The present invention relates to detection field, specifically a kind of ultrasonic tool detection devices.
Background technology
Application of the ultrasonic wave added Machining Technology for Cutting in national economy productive life is increasingly extensive.With traditional processing not
Together, in ultrasonic wave added machining cutter while doing cutting movement, bearing cutting force, also in the driving of ultrasonic vibration system
Under do the vibration of the multi-forms such as high frequency stretching/compressing, torsion, swing.Dither is to cutter quality, particularly tool surface
Integrality proposes high requirement, if there are micro-crack or other manufacturing defect in cutter interior, under high frequency forced vibration,
Crack Extension then can occur causes cracking of cutter damaged, easily causes the part to be processed even damage of lathe.Therefore, in reality
Before machining, cutting performance is tested, it is necessary for will have defective cutter detection scrapping.
Both at home and abroad Patents are segmented into following a few classes：1. existed using the stress of supersonic frequency change, tested
Test specimen on, apply the alternate stress of high frequency in the short time to exemplar, observe test specimen fracture or surface topography situation sentencing
Whether disconnected exemplar reaches standard.For example a kind of temperature checking method patent suitable for cutter fatigue damage, by detection
The features such as the linear coefficient for being excited resonance wave that Ultrasonic machining instrument sends when by being motivated by ultrasound, the material and knot to instrument
Structure makes fatigue damage detection.The ultrasonic cutter that the less efficient inapplicable mass detection of this detection method is dispatched from the factory.2. it is similar to
The Cleaning Principle of sound emission, by launching certain frequency, the ultrasonic signal of phase place to test specimen.By surpassing that collection is reflected
Acoustic signals are judging the crackle of test specimen, or defect situation.If not having the defects such as crackle when cutter just begins to use,
And simply metallographic structure insufficient strength, also result in cutter and rupture in the loaded situation of high frequency band.So use the party
Rule cannot accurately detect ultrasonic cutter.3. fall-of-potential method detects specimen crack, and the detection detection method is used for pipe over long distances
The crack detection aspect in road, such as a kind of fatigue at low temperatures crack growth rate experimental rig is detected using direct current potential drop method
The crack Propagation state of metal material.If simple occur the crack detection aspect that fall-of-potential method is used in ultrasonic cutter
Larger error.Because cutter is in the case of non-vibrating, crackle does not stress, and does not have in closure state, resistance and normal condition
There is too big difference.And ultrasonic cutter can cause the opening and closing of crackle under stress, Vibration Condition, so this patent is made changing
Enter, allow it in stress, vibrational state tests its electrical quantity, improve the accuracy rate of detection.
This patent combines frequency and amplitude detection using the ultrasonic tool detection devices of designed, designed, and fall-of-potential method is detected,
Free Modal, the method for pressure Modal detection, by a complete testing process, improves ultrasonic cutter quality testing accurate
Rate, reduces the probability that fracture failure occurs in process in the ultrasonic cutter that dispatches from the factory, improves production efficiency and process safety
