Description
Technical field
The present invention relates to a kind of fixture, a kind of fixture for beams of metal vibration detection.
Background technology
Vibration test is the various Environmental Virbration Influences that artificial product is suffered from transportation, installation and use environment, this test
It is the various Environmental Virbration Influences that suffered under transportation, installation and use environment of analog equipment, is used for determining that product whether can
Bear the ability of various ambient vibration.Vibration test is that evaluation components and parts, parts and complete machine in intended transport and use environment
In resistivity.
One leads to detection thinks that most-often used mode of vibration can be divided into sinusoidal vibration and random vibration two kinds.Sinusoidal vibration is in laboratory
Through frequently with test method, rotate with simulation, pulse, shake (to be gone out on boats and ships, aircraft, vehicle, spacecraft
Existing) produced vibration and product structure resonance frequency analysis and resonance point is resident is verified as main, it is divided into again frequency sweep to vibrate
With determine frequency vibration two kinds, its harsh degree depends on frequency range, amplitude, duration of test runs.Random vibration is then with simulation
The assessment of product globality structure shock resistance and transport environment under packed state, its harsh degree depend on frequency range,
GRMS, duration of test runs and axially.
The fixture form being currently used for beams of metal vibration detection is various various, but the problem that the most generally there is the following aspects:
1, clamp structure or design parameter unreasonable (such as rigidity and quality etc.), cause beams of metal chucking appliance system at test model
Enclose the resonance that interior appearance causes because of fixture mismate.
2, chucking power is big not, and during detection, beams of metal easily occurs loosening with fixture junction.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of fixture for beams of metal vibration detection, improve fixture to gold
Belong to the chucking power of beam, it is to avoid vibration table produces resonance with fixture, be conducive to being more effectively transferred to the motion of vibration table
Beams of metal.
It is an object of the invention to use following technical proposals to realize:
A kind of fixture for beams of metal vibration detection that the present invention provides, described fixture includes base, riser and baffle plate, described
Base is horizontally set on vibration table, and described riser is vertically arranged on base, is vertically arranged gold between described riser and baffle plate
Belonging to beam, one end of described beams of metal and the upper surface of base, it thes improvement is that: described base sets with the angle of riser
There is the stiffener being respectively perpendicular described base and riser.
Wherein, described stiffener and base and riser are for being welded to connect, and described stiffener is provided with circle with the contact angle of base and riser
Arc perforate.
Wherein, described circular arc perforate is quadrant hole.
Wherein, described base top edge uses chamfered；Described base edge is the most vertically provided with eight countersunk head unthreaded holes.
Wherein, described vibration table is provided with the screw corresponding with described base.
Wherein, described base and vibration table are connected by screw；Described screw is provided with elastomeric pad.
Wherein, described riser is rectangle, and with described base for being welded to connect, described riser corner is provided with four countersunk head unthreaded holes.
Wherein, described baffle plate is provided with the unthreaded hole corresponding with described riser, and described baffle plate and riser are bolted.
Wherein, the contact surface of described riser and baffle plate and described beams of metal is that annular knurl processes.
Wherein, described base, stiffener, riser and baffle plate all use aluminum material, and its surface uses bead.
Compared with the prior art, the present invention reaches to provide the benefit that:
1, the parts in fixture all use the aluminum material that density is less, and under equal conditions gross mass is lighter.
2, stiffener makes riser preferable with the connection integrity of base.
3, use eight screws to be fixed on vibration table by base, and on screw, install elastomeric pad additional, make base and vibration
The connection of table top is the tightst, improves the rigidity that structure is overall.
4, the reduction of quality and increasing of rigidity, make fixture itself have higher natural frequency, it is to avoid vibration table and folder
Tool produces resonance, is conducive to the motion of vibration table is more effectively transferred to beams of metal.
5, the contact surface of riser and baffle plate and beams of metal all uses annular knurl to process, and adds the roughness on its surface, thus adds
Chucking power to beams of metal.
6, utilize securing member to be fixed between baffle plate and riser by beam, increase the fixture chucking power to beams of metal base plate, prevent it
Process of the test occurs loosen and affect Detection results.
7, a quadrant hole is had on the angle that stiffener contacts with base and riser, to control stiffener and riser, the end
Deflection during seat welding, it is ensured that the perpendicularity between riser and base upper surface.
8, compact conformation, surface is through bead, anticorrosion antiwear, good looking appearance.
9, simple installation, is greatly improved work efficiency.

Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in further detail.
As a example by the present embodiment fixture for beams of metal vibration detection, as shown in Figure 1 to Figure 3, the embodiment of the present invention provides
Fixture for beams of metal vibration detection includes: base 1, screw 2, stiffener 3, fastening bolt 4, riser 5, nut 6,
Baffle plate 7.
Base 1 is provided with eight through countersunk head unthreaded holes, is fixed on vibration table by base 1 by screw 2, and screw 2
On install elastomeric pad additional, make base 1 the tightst with the connection of vibration table, improve the rigidity of structure entirety；On base 1
Edge does chamfered, scratches skin when preventing installation from safeguarding.
Riser 5 is vertically welded on base 1, and stiffener 3 is connected by welding manner with base 1 and riser 5 respectively, puts more energy into
Plate 3 has a quadrant hole on the contact angle of base 1 and riser 5, to control stiffener 3 and riser 5 and base
Deflection during 1 welding, thus ensure the perpendicularity of riser 5 and base 1 upper surface；Stiffener 3 can increase the firm of fixture
Degree, improves the dynamic trait of fixture.
