The dynamometer has the advantages of simple structure, favorable performance, low cost and high precision, and the two three-way piezoelectric force sensing elements can reach an international specified dynamic cutting dynamometer standard. The present invention can carry out accurate measurement and static, dynamic and on-line measurement and has wide purposes.
Description
The invention belongs to cutting metal and when nonmetal, measure the surveying instrument of cutting force.
Though existing piezoelectric type dynamometer dynamic property increases than other type dynamometer, complex structure mostly is fabricated structure.The piezoelectric force transducer that needs during measurement is more, and for example the 9257A of Switzerland Kistler company dynamometer will be with 4 three-way piezoelectrics quartz force transducers, and this sensor process complexity, the technical requirement height, and difficulty is manufactured, and cost is very high.So the dynamometer cost made from such sensor is also very high.
The objective of the invention is to develop a kind of simple in structure, dynamometer is cut in the good piezoelectric type milling of dynamic property.Dynamometer adopts the two resilient ring symmetrical structures of monoblock type, only need with two triaxial pressure photosensitive elements, can reach the standard code of " the dynamically type cutting dynamometer " of international CIRP-TSCC (international production engineering research association---the cutting council) regulation, dynamometer has higher static state and dynamic property.Since simple in structure, the expensive pressure transducer of half saved, so this dynamometer cost reduces greatly.It has higher power-photoelectric transformation efficiency, can measure static state, dynamic cutting force, also can online precision measurement instantaneous cutting force.
Technical scheme of the present invention is a piezoelectric quartz monoblock type three-dimensional mill Milling Force instrument, and by dynamometer body 1, piezoelectricity three-dimensional force sensing element 2 is formed.Its dynamometer body 1 is a monoblock type left-right symmetric structure, a is square in the middle of dynamometer body 1 is shaped as, respectively there is the resilient ring b of a symmetry square both sides, there are two semi-ring holes and elongate slots to communicate in each resilient ring b, two piezoelectric quartz three-dimensional force sensing elements, 2 difference clampings in the elongate slots of resilient ring b, are leaned on magnitude of interference pretension.The above and below of force sensing element is by fluid sealant 4 sealings, and three direction extension lines 3 on the piezoelectric quartz force sensing element are by outside hollow screw 7 lead bodies.The top of two resilient ring b is by upper cover plate 5 sealing, and the bottom is with lower cover 6 integral sealings, upper and lower cover plate 5 and 6 and the dynamometer body between with electron beam or laser welded seal.The fixed head c in the resilient ring b outside is used for fixing dynamometer, and groove is arranged on the plate, and mounting screw can penetrate fixedly dynamometer body.Be contained in two piezoelectricity three-dimensional force sensing elements 2 in the elongate slots by the X0 that bears the tension and compression effect ° cut type, bear Y0 ° of cut type of shearing effect and form, can measure F

ZThe power of three directions.After two quartz wafers were connected in parallel, lead 3 was outside hollow screw 7 lead bodies.Several equally distributed threaded holes that is used to install workpiece are arranged on the square a of dynamometer body 1.
During use, earlier part is fixed on the dynamometer with screw and pressing plate, the dynamometer that part will be housed then is fixed on the worktable of lathe.During cutting, act on the cutting force on the part, just the plane effect that passes through two resilient rings is decomposed into F through force sensing element with acting force automatically on force sensing element

ZThree mutually perpendicular direction outputs can determine cutting force.
Static force when the present invention can be used to measure grinding, Milling Process, dynamic force and transient force also can be used as on-Line Monitor Device or adaptive control system feedback element.The measuring accuracy height, long service life, of many uses.
Accompanying drawing 1 is the front view of dynamometer, and wherein: a is a square block, and b is a resilient ring, and c is a fixed head.
Accompanying drawing 2 is cut-open views of dynamometer, wherein: the 1st, dynamometer body, the 2nd, pressure three-dimensional force sensing element, the 3rd, extension line, the 4th, fluid sealant, the 5th, upper cover plate, the 6th, lower cover, the 7th, hollow screw.
Accompanying drawing 3 is two piezoelectricity three-dimensional force sensing element circuit diagrams.
Most preferred embodiment as shown in Figure 1, dynamometer body material is an alloy steel, forges after solution treatment.The geometric parameter of elasticity semi-ring is selected to guarantee that each phase rigidity is identical.Magnitude of interference when force sensing element is packed dynamometer into generally is taken as 0.3～0.5mm, and pretightning force is 8000～13000N.For guaranteeing each to a minimum principle of horizontal interference, the position to force sensing element in elongated slot will accurately be debugged during assembling.During measurement, workpiece is fixed on the dynamometer body, measuring instrument is fixed on the worktable of lathe.When cutting, cutting force can conveniently be measured by force sensing element.Easy to use, accurately reliable.
