Description
Technical field
The invention discloses a kind of experimental provision for the vibration of round cross-section rod basic excitation, belongs to mechanical oscillation experiment
Vibration experiment clamping device under technical field, more particularly to a kind of round cross-section rod basic excitation for tackling different cross section size.
Background technology
In vibration-testing, the fixed clamp clamp of test specimen is typically necessary design and manufacture, and round cross-section rod is by base
The fixture of plinth excitation has a wide range of applications.Realized for the rod member of different cross section diameter by changing some part in fixture
Coordinate clamping, rather than re-start global design, this bring conveniently for experiment.In order to meet fixture to different chis
The requirement of very little rod member versatility, the fixture of suitable different size rod members is designed with meaning energetically.
The content of the invention
In order to meet the needs of fixture is to different size rod member versatilities, it is used to adapt to different cut the invention provides one kind
The vibration tong device of face diameter rod member clamping, the fixture can effectively be clamped to different cross section size rod member, carry out base
Vibration experiment under plinth excitation.
To realize purpose that fixture clamps to different size rod members, the present invention is divided into three parts, respectively base rack
(1), pipe clamp (2,3) and fastening bolt (4,5,6).In order to reach the purpose of different size rod members clamping, the first pipe clamp (2) and
Second pipe clamp (3) uses standard component, on the basis of rod member pilot hole (7) center, is coaxially mounted on base rack (1).According to
The pipe clamp (2,3) that rod member used in experiment (9) selection adapts to.It is correspondingly provided with base rack (1) and fixes the first pipe clamp (2) and second
The pipe clamp mounting hole (8) of pipe clamp (3), the first pipe clamp (2) and the second pipe clamp (3) are co-axially mounted on the basis of rod member pilot hole (7)
On base rack (1).Pipe clamp mounting hole (8) is engaged with pipe clamp fastening bolt (5), is provided with base rack (1) multigroup
The pipe clamp mounting hole (8) of different pore size, for installing various sizes of pipe clamp (2,3).The level at a pair of pipe clamp mounting hole centers
Distance matches with the distance of pipe clamp bolt hole.Therefore, be drilled with base rack multigroup different-diameter, varying level distance into
To pipe clamp mounting hole (8).Base rack (1) is fixed on vibration table surface, and basic branch is fixed with basic fastening bolt (4)
Frame (1) is on vibration table surface.Rod member is realized by rod member pretension bolt (6) through rod member pilot hole (7) and fastened.First pipe clamp
(2) the coaxial fastening on 2 points is carried out to rod member with the second pipe clamp (3), and basis is fixed to by pipe clamp fastening bolt (5)
On support (1).
Base rack (1) uses 304 steel, and the first pipe clamp (2) and the second pipe clamp (3) use duralumin, hard alumin ium alloy.
The present invention technical advantage be：By the size of rod member needed for experiment, different pipe clamps is selected to implement clamping, not
Realized in the case of changing base rack and the purpose clamped is realized to various sizes of rod member, fixture is versatile.Meanwhile save
The expense of design iterations manufacture.
