Problems solved by technology

It can be seen that when the vibration, frequency, and amplitude generated at different time stages are output by the fixture, it may actually be accompanied by multi-order resonance due to objective conditions (deterioration of fixture effectiveness, affected by data transmission rate, etc.), and the external influence cannot be uniform.

Embodiment 1

[0037] One end of the first elastic rod 3 away from the slide rail assembly is connected to a plurality of second elastic rods 4 through the conversion head 8.

[0038] The electric energy measuring instrument of this embodiment may be a single-phase electric energy meter.

[0040] In this embodiment, the connecting member shown may be a screw, and the first mounting hole 7 and the second mounting hole 11 are threaded holes.

[0042] Further, as shown in Figure 4, the slide rail assembly includes a clamp 2, a slide rail 5, and a slider 12, and the slide rail 5 is along the second direction

[0044] A number of sliders 12 are installed on each slide rail 5, and the number of the sliders 12 is determined according to the number of actual electric energy measuring instruments. exist

[0046] Further, as shown in FIG. 7, the inner side of the slider 12 forms a concave structure, and the side surface of the slider 12 is provided with a threaded hole to connect with the

[0047] Further,...

Embodiment 2

[0062] Step 3: place the cover plate 10 above the electric energy meter, and fix the cover plate 10 and the base 1 by screws.

Abstract

The invention discloses a vibration test fixing device and method for an electric energy measuring instrument. The technical proposal is as follows: a base is included, a plurality of first elastic rods are arranged symmetrically along the first direction of the base, and one end of the first elastic rod passes along the first direction of the base The slide rail assembly arranged in two directions is connected to the base; wherein, the second direction is perpendicular to the first direction; the other end of the first elastic rod is connected to a plurality of suction cups, and the first elastic rod can be bent so that the suction cups are adsorbed on the surface of the electric energy measuring instrument . The invention can keep the electric energy measuring instrument stable during the vibration test, and avoid distortion of the amplitude of the electric energy measuring instrument.

Description

A vibration test fixture and method for electric energy measuring instruments technical field The present invention relates to vibration test field, relate in particular to a kind of vibration test fixture for electric energy measuring instrument and methods. Background technique The mechanical vibration test of the electric energy meter adopts the shock, vibration, friction temperature etc. The vibration test is a key technical node to verify the reliability of the electric energy meter. During the test, the shaker fixture is a guarantee A pivot tool that reliably clamps the test piece and transmits energy to the shaking table movement. [0003] In general, most of the test pieces are often passively matched with the rigid locking of the fixture to meet the support strength or the clamping condition. Therefore, it can only be operated by manually tightening the screws; in this case, when the vibration changes speed according to a sinusoidal law The degree is equa...
