Description
The present invention is the instrument that belongs to the cutting force when measuring metal and nonmetal cutting.
Though existing piezoelectric type cutting dynamometer dynamic property improves a lot than other type dynamometer, but structure is complicated, volume is bigger, the piezoelectric force transducer quantity that needs is more, and (for example the 9257A of Switzerland Kistler company force plate/platform will be with 4 three-way piezoelectrics quartz force transducers, the 9263A turning dynamometer needs 3 two-way 3 unidirectional totally 6 piezoelectric quartz force sensors), and this sensor process complexity, the technical requirement height, be difficult to make, cost is very high, and (as 86 years prices of 9257A dynamometric system is 21590 dollars so the dynamometer cost that makes with such sensor is also very high, amounted to 60450 yuan of Renminbi at that time).In addition,, have than big difference, will cause dynamic measurement error with actual cutting tool state because most dynamometer quality are bigger.Owing to above reason, present dynamometer is many to be used in the laboratory, is difficult to be applied in the actual production.
The objective of the invention is to develop the piezoelectric type turning dynamometer that a kind of volume is little, in light weight, structure is simple and direct, dynamic property is good.Whole dynamometer such as same the normal cylindrical lathe tool, only form by elastic cutter bar and the quartzy force sensing element of three-way piezoelectric of a high rigidity, make that dynamometer is static to improve a lot with dynamic property, reach the one cutting council of the international production engineering of international CIRP-TSCC(research association) " dynamically type cutting dynamometer " standard of regulation.In addition, because simple in structure, save many expensive piezoelectric force transducers, so this dynamometer cost also can reduce greatly.It is suitable for the dynamic and instantaneous cutting force of online precision measurement, also the static cutting force of energy measurement.
Concrete implementation step method of the present invention and technology
