Abstract

The utility model discloses a realize three axial vibration's test fixture simultaneously, including the transitional coupling bottom plate, the transitional coupling bottom plate passes through the bolt and is connected with the shaking table, be equipped with at least one counter bore on the transitional coupling bottom plate, weld two mutually perpendicular's L shape riser on the transitional coupling bottom plate respectively. The utility model discloses a realize three axial vibration's test fixture simultaneously, simple structure, the design ingenious, easy dismounting, when carrying out the experiment of three axial vibration, not needing three sets of vibration test anchor clamps of manufacturing and designing, reducing manufacturing cost, economic nature is high.

Description

A kind of test fixture simultaneously realizing three-axial vibration
Technical field
This utility model belongs to test fixture technical field, particularly to a kind of test fixture realizing three-axial vibration simultaneously.
Background technology
Vibration test is a kind of common environmental test in engineering field, mainly finds the defect during product development by the excitation of vibration test, thus improves product design, improves the reliability of product.
Vibration test is generally realized by vibration mechine, and test products is connected by test fixture with vibration table, thus is delivered on product by the vibrational energy on vibration table.What vibration mechine was common is all the vibration table of single shaft excitation at present, traditional test fixture and test method can only carry out vibration test in an axial direction, when carrying out three-axial vibration test when there being typical products in mass production to need, need to manufacture and design three set vibration test fixtures, the most less economical.
Summary of the invention
This utility model is to solve existing vibration test fixture to be not applied for the technical problem of three-axial vibration test, proposes a kind of test fixture simultaneously realizing three-axial vibration.
For solving the problems referred to above, this utility model adopts the technical scheme that: a kind of test fixture simultaneously realizing three-axial vibration, and including transition connecting bottom board, described transition connecting bottom board is connected with vibration table by bolt;Described transition connecting bottom board is provided with at least one counterbore;Two pieces of orthogonal L-shaped risers it are respectively welded on described transition connecting bottom board.
Preferably, described L-shaped riser is provided with screwed hole.
Preferably, in described screwed hole, inlay steel lining, strengthen intensity, extend screwed hole service life.
Preferably, described L-shaped riser weld avoids the counterbore on transition connecting bottom board.
Preferably, described transition connecting bottom board roughness grade is not less than 6.3.
Compared with prior art, the beneficial effects of the utility model are:
A kind of test fixture simultaneously realizing three-axial vibration that this utility model provides, simple in construction, is skillfully constructed, easy accessibility;When carrying out three-axial vibration test, it is not necessary to manufacture and design three set vibration test fixtures, reducing manufacturing cost, economy is high.
Accompanying drawing explanation
Fig. 1 is a kind of test fixture structural representation simultaneously realizing three-axial vibration.
Drawing reference numeral: 1, transition connecting bottom board;11, counterbore;2, L-shaped riser;21, screwed hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is done more detailed description.
Seeing accompanying drawing 1, a kind of test fixture simultaneously realizing three-axial vibration, including transition connecting bottom board, described transition connecting bottom board is connected with vibration table by bolt;Described transition connecting bottom board is provided with at least one counterbore;Two pieces of orthogonal L-shaped risers it are respectively welded on described transition connecting bottom board.
Further, use duralumin as rapidoprint, by actual size, transition connecting bottom board is processed into circle.
Further, described transition connecting bottom board roughness grade is not less than 6.3.
Further, described L-shaped riser is provided with screwed hole.
Further, in described screwed hole, inlay steel lining, strengthen intensity, extend screwed hole service life.
Further, described L-shaped riser weld avoids the counterbore on transition connecting bottom board.
Listed above is only specific embodiment of the utility model.Obviously, this utility model is not limited to above example, it is also possible to have many similar reshapings.All deformation that those of ordinary skill in the art can directly derive from this utility model disclosure or associate, are all considered as this utility model scope of the claimed.
