Description

A Test Fixture Simultaneously Realizing Three-axis Vibration

technical field

The utility model belongs to the technical field of test fixtures, in particular to a test fixture capable of simultaneously realizing triaxial vibration.

Background technique

Vibration test is a common environmental test in the engineering field. It is mainly to find defects in the product development process through the excitation of vibration test, so as to improve product design and improve product reliability.

Vibration tests are usually carried out on a vibration test bench. The test product is connected to the vibration table through a test fixture, so that the vibration energy on the vibration table is transferred to the product. At present, the most common vibration test benches are single-axis excitation vibration tables. Traditional test fixtures and test methods can only perform vibration tests in one axis. Three sets of vibration test fixtures are expensive and economical.

Contents of the invention

In order to solve the technical problem that the existing vibration test fixture cannot be applied to the three-axis vibration test, the utility model proposes a test fixture that simultaneously realizes the three-axis vibration.

In order to solve the above problems, the technical solution adopted by the utility model is: a test fixture that realizes three-axis vibration at the same time, including a transition connection bottom plate, and the transition connection bottom plate is connected to the vibration table through bolts; There is at least one counterbore; two mutually perpendicular L-shaped vertical plates are respectively welded on the transition connection bottom plate.

Preferably, threaded holes are provided on the L-shaped vertical plate.

Preferably, the threaded hole is embedded with a steel bushing to enhance the strength and prolong the service life of the threaded hole.

Preferably, the welding position of the L-shaped vertical plate avoids the counterbore on the bottom plate of the transition connection.

Preferably, the surface roughness grade of the transition connection bottom plate is not lower than 6.3.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model provides a test fixture for simultaneously realizing three-axis vibration, which has simple structure, ingenious conception, and convenient disassembly and assembly; when performing a three-axis vibration test, it is not necessary to design and manufacture three sets of vibration test fixtures, which reduces manufacturing costs and is economical. high sex.

detailed description

Embodiments of the present utility model will be described in more detail below in conjunction with the accompanying drawings.

Referring to accompanying drawing 1, a kind of test fixture that simultaneously realizes three axial vibrations comprises a transition connection bottom plate, and the transition connection bottom plate is connected to a vibrating table through bolts; the transition connection bottom plate is provided with at least one counterbore; the transition connection bottom plate Two L-shaped vertical plates perpendicular to each other are respectively welded on the connection base plate.

Further, duralumin is used as the processing material, and the transition connection bottom plate is processed into a circle according to the actual size.

Further, the surface roughness grade of the transition connection bottom plate is not lower than 6.3.

Further, the L-shaped vertical plate is provided with threaded holes.

Further, the threaded hole is embedded with a steel bushing to enhance the strength and prolong the service life of the threaded hole.

Further, the welding place of the L-shaped vertical plate avoids the counterbore on the bottom plate of the transition connection.

What enumerated above is only the specific embodiment of the utility model. Apparently, the utility model is not limited to the above embodiments, and many similar modifications are also possible. All deformations that can be directly derived or associated by those skilled in the art from the content disclosed in the utility model should be considered as the protection scope of the utility model.
