Description
Technical field
The present invention relates to Milling Force fields of measurement, and in particular to a kind of suitable for the folder with vibration-proof structure on dynamometer
Tool.
Background technology
Machining is widely used in the fields such as space flight, automobile, processing precision direct influence workpiece quality.And in milling
Cheng Zhong, Milling Force as one of parameter important in process of metal working, stability, workpiece of its size variation to process
The consumption of surface quality, cutter life and machine power has influence, is to design, manufacture one of fixture reference factor, therefore cutting force
Accurately measure there is extensive use in field of machining.The effect of fixture is to fix and limit processing work in process
The movement of part, and it is occupied correct locus, for secondary process or detection means.But common dynamometer fixture by
Cutter is subject in by process to be influenceed with work pieces process impact, and produces vibration therewith so as to the use band to dynamometer
Carry out detrimental effect.Traditional dynamometer fixture is without vibration absorber, it is therefore desirable to a kind of new dynamometer fixture, Ji Nengshi
Existing tradition dynamometer fixture is easy for installation, positioning is accurate, the steady basic function of fixation, and processing vibration can be as far as possible reduced again to dynamometer
Use the adverse effect for causing.
The content of the invention
The utility model is directed to existing dynamometer fixture without vibration absorber defect, and then aims at the existing dynamometer of solution
Fixture is influenceed without that can accurately measure Milling Force by cutting vibration factor, there is provided one kind is applied on dynamometer with vibration damping
The fixture of structure.
The utility model to achieve the above object, is realized by following technology:
A kind of fixture suitable for carrying vibration-proof structure on dynamometer, its composition includes:With vibration-proof structure jig main body,
It is described with rectangular cavities are provided with vibration-proof structure jig main body, the rectangular cavities are provided with permanent magnetic along central line
Iron, the permanent magnet is around with coil.
The cavity is rectangular seal cavity, and it is internal full of magnetic rheological liquid, and the coil is complete with the permanent magnet
Entirely in magnetic rheological liquid environment.
Described main body is in integrally I-shaped structure, and its two sides is machined with Baltimore groove, and the Baltimore groove is set along edge
There is workpiece positioning through hole.
Described workpiece positioning through hole be divided into 2 rows often arrange 6 it is parallel be distributed in the side of jig main body two, the workpiece positioning is logical
Bore dia is 8mm.
The jig main body upper surface is machined with the counterbore of fixed dynamometer, and the counterbore often arranges 3 distributions, institute in 2 rows
Counter bore hole diameters are stated for 12mm.
Described jig main body, its length, width and height are respectively 170mm, 120mm, 28mm.
Beneficial effect:
Overall structure advantages of simple of the present invention, and fixture function basic demand is disclosure satisfy that, the installation, positioning to workpiece are accurate
Really, clamping is consolidated, while jig main body two ends are provided with Baltimore groove, alleviates the total quality of fixture, is easily installed and dismounting.
The present invention is that a kind of vibration-proof structure that carries is applied to special fixture on dynamometer, and the vibration-proof structure that it is carried has very
Good effectiveness in vibration suppression.When dynamometer is used, hot-wire coil can produce corresponding magnetic field, and magnetic rheological liquid is in externally-applied magnetic field ring
There is sensitivity very high, its viscosity and density change under border, and then produce damping force, absorb the energy that vibration is produced,
Good effectiveness in vibration suppression is reached, the precision that dynamometer measures cutting force is improved.
Coil current size intensity controlled of the invention, and then control the rigidity value of magnetic flow liquid and the damping for producing
Power, with more preferable effectiveness in vibration suppression.
The present invention uses permanent magnet, improves inside cavity magnetic field environment, improves the excursion of magnetic field intensity, makes band
There is vibration-proof structure fixture effectiveness in vibration suppression more obvious.
