Embodiment 1

[0094] Embodiment 1 of the present invention provides a vibrating fixture, which is a combined flipping vibrating fixture, used to fix the product to be tested in the vibration test, including a fixture main body with at least one mounting surface and detachably fixed by a locking structure The connector at the mounting surface of the fixture main body, on which the product to be tested is detachably fixed, the fixture main body has three bottom surfaces, one of which is detachably fixed on the vibrating device (in In this embodiment, it is a vibrating table), the bottom surface is a plane, and the three bottom surfaces are adjacent to each other and are perpendicular to each other. The main body of the fixture also has three adjacent surfaces. At least one of the surfaces is the installation surface, and the three surfaces are respectively opposed to the three bottom surfaces, and the three surfaces are respectively arranged along three directions perpendicular to each other, ...

Embodiment 2

[0127] In the second embodiment, the product to be tested is an electronic throttle. The second embodiment is mainly different from the first embodiment at the installation station of the product.

[0128] In the first embodiment, the installation station is a plane, and there is a fourth installation hole on the plane, and the electronic throttle is fixed on the connecting piece 2 through the fourth installation hole. combine Figure 9-10 , In the second embodiment, a different installation station is provided. The installation station has an L-shaped groove in cross section, and the L-shaped groove matches the size of the electronic throttle. That is to say, Embodiment 2 provides another way of setting up the installation station. In addition, the vibrating fixture is also provided with a gantry unit for fixing the product wiring harness. For the introduction of the gantry unit, please refer to Embodiment 6 of the present invention. In addition, other technical solutions a...

Embodiment 3

[0130] In this embodiment, compared with the first embodiment, the structure of the connector 2 is changed to standardize the direction of the product wiring harness.

[0131] A plurality of the connectors 2 have the same size. In this example, if Figure 11 As shown, the connector 2 includes a first plate 8 and a second plate 9 that are detachably fixedly connected to the first groove 3, the first plate 8 and the second plate 9 are integrated, and the first The plate 8 has one side fixed in the first groove 3 and the other side fixedly connected with the second plate 9 on which the product to be tested is fixed.

[0132] In this embodiment, the first plate 8 and the second plate 9 are both rectangular plates, and the first groove 3 is a U-shaped groove, please refer to Figure 5 and Figure 11, the interior of the first groove 3 has two parallel sides, which are the first side 31 and the second side 32, and the second plate 9 has the third side 91 and the fourth side 92 pa...

Abstract

The invention provides a vibration clamp. The vibration clamp includes a clamp body with at least two installation surfaces and a connecting piece fixed to the installation surfaces via a locking structure and used to fix a product, the clamp body includes three bottom sides connected to vibration equipment, the three bottom sides are adjacent pairwise and vertical pairwise, the clamp body also includes three surfaces which are adjacent pairwise, at least two of the three surfaces are installation surfaces, the three surfaces are opposite to the three bottom sides respectively, the three surfaces are arranged along three directions vertical to one another, any bottom side is adjacent to the other two bottom sides and two surfaces, and the weights of the clamp body, the locking structure and the connecting piece are set so that the distances between the whole gravity center of the clamp body, locking structure and connecting piece and the three bottom sides are equivalent. The vibration clamp and vibration test method provided by the invention can satisfy installation requirements of various products, time of direction replacement is shorter, the transfer sequence of a vibration force is reasonable, and the product is not damaged due to repeated mounting and dismounting.

Description

technical field [0001] The invention relates to the field of vibration testing, in particular to a vibration fixture and a vibration testing method. Background technique [0002] When the product installed on the vehicle is driven on the road, it will be excited by the random vibration caused by the rough road along with the vehicle. In addition, the product installed on the engine will also be excited by the sinusoidal vibration from the engine at the same time. Therefore, it is necessary to conduct a vibration test on the product on the vehicle to assess the structural fatigue strength of the product, that is, whether the product will cause fatigue failure and damage due to the simulated actual working conditions. [0003] When performing vibration tests on products on vehicles, it is often necessary to perform vibration tests on products belonging to the EMS (Automotive Engine Management System). EMS is mainly composed of air management system, electronic controller, fue...
