Description

一种用于电子测量仪振动实验的夹具A fixture for vibration experiments of electronic measuring instruments 技术领域Technical field

电子测量仪由于大多为手持式，在进行测量时会产生抖动，因此在生产过程中，需要对电子测量仪振动状态的测量精度进行试验。Since most electronic measuring instruments are handheld, they will vibrate when measuring. Therefore, during the production process, it is necessary to test the measurement accuracy of the vibration state of the electronic measuring instruments.
然而在实际试验过程中，现有的对电子测量仪的安装大多为螺栓或螺钉等刚性夹持连接，在振动过程中，容易造成测量仪外壁的挤压变形，而现有的柔性夹持为气囊充气式的夹持，这样的夹持容易使得气囊造成对振动幅度的缓冲，从而降低振动幅度，影响测量仪在振动过程中的检测精度，使得试验的数据不具有参考性。However, in the actual test process, most of the existing electronic measuring instruments are installed with rigid clamping connections such as bolts or screws. During the vibration process, it is easy to cause extrusion and deformation of the outer wall of the measuring instrument. However, the existing flexible clamping is Air bag inflatable clamping, such clamping can easily cause the air bag to buffer the vibration amplitude, thereby reducing the vibration amplitude, affecting the detection accuracy of the measuring instrument during the vibration process, making the test data non-referential.
