The installation condition of the product 30 to be tested in actual use can be well simulated, and multiple times of punching and thread processing can be carried out on the transition plate 11, the side plate or the bearing plate for repeated use, so that the test process is accelerated, and meanwhile, the manufacturing cost and the maintenance cost of the reliability test clamp 10 are reduced.
5. On the product 30 that will await measuring is fixed in the test anchor clamps that await measuring with the second installed part after the mounting hole counterpoint through second mounting hole and the product 30 that awaits measuring, the screw is specifically chooseed for use to the second mounting hole, and the second installed part specifically for example is screw or bolt, can improve the joint strength between product 30 and the reliability test anchor clamps 10 that await measuring, can transmit the vibration load of reliability test effectively to the product 30 that awaits measuring, has guaranteed experimental quality and experimental effect.
6. The magnesium-aluminum alloy plate is designed and manufactured in a light weight mode, the weight of the reliability test fixture 10 is reduced to the maximum extent, more products to be tested 30 can be installed for testing, and the test time and the test cost can be reduced.
7. The reliability test fixture 10 is of a frame structure, all components are connected through screws, and can be assembled in the later period, so that a sufficient product installation space is provided, and the product installation before the test, the product removal after the test and the maintenance operation of the product in the test process are facilitated.
In an embodiment, referring to fig. 8 again, a reliability testing apparatus includes the reliability testing jig 10 of any of the above embodiments, and further includes a vibration table 20 and a sensor 40. The transition plate 11 is installed on the vibration table 20. The sensor 40 is mounted on the reliability test jig 10. Specifically, the sensor 40 is fixed to the reliability test jig 10 by bonding.
When the reliability test device is used, the transition plate 11 is fixedly arranged on the vibration table 20, the product 30 to be tested is specifically a multi-group component product, the multi-group component product is divided into a plurality of single-group components, the plurality of single-group components are respectively and fixedly arranged on the transition plate 11, the first side plate 12, the second side plate 13 and the first bearing plate 14 according to the actual volume size, and then the vibration table 20 vibrates at the preset vibration frequency to simulate the actual working environment of the product 30 to be tested and develop the reliability test. When the transition plate 11 vibrates, the vibration load is synchronously transmitted to the first side plate 12, the second side plate 13 and the first bearing plate 14, so that the transition plate 11, the first side plate 12, the second side plate 13 and the first bearing plate 14 synchronously vibrate at a preset vibration frequency. Therefore, a proper clamp does not need to be machined and manufactured for each single component of a multi-component product, so that delay of progress can be avoided, and clamp cost is reduced; the reliability test of the single-unit component is not required to be carried out separately, the installation requirements of the test of the multi-unit component product can be met to a greater extent, the reliability test of the multi-unit component product can be synchronously carried out, the authenticity of the test result of the reliability test is higher, the test efficiency of the multi-unit component product can be improved, manpower and material resources are saved, and the test cost is reduced.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
