[0002] Acceleration is an important parameter for calculating the instantaneous dynamic load and spatial position of aircraft, rockets and ships. An accelerometer is an instrument that measures acceleration and can measure acceleration continuously.

[0003] For accelerometers used in aerospace systems, special considerations need to be made in design and manufacturing. For example, the high temperature resistance of the accelerometer should reach 705°C. Therefore, the accelerometers used in aerospace systems need to be tested for their high temperature resistance after production. However, in the prior art, when the accelerometer core high temperature resistance initial test device tests multiple accelerometers at one time, it is usually to first install multiple accelerometers in sequence on a whole core tooling block, and then use a heating plate to heat the core tooling block, and set a heat preservation cover on the outside of the core tooling block to perform the accelerometer core high temperature resistance test. This method requires the accelerometer core to be installed on the core tooling block one by one during each test, and after the test is completed, the accelerometer cores need to be disassembled one by one, which is time-consuming, resulting in a small number of accelerometer cores tested by the initial test device within a limited working time, and low test efficiency.

In this embodiment, the heating plate is arranged in the middle of the core tooling block 2, and the plane where the heating plate is located is parallel to the plane where the core tooling block 2 is located. This arrangement can achieve an equal distance between the accelerometer core 5 to be tested and the heating plate, and the heating is uniform, so that the test temperature will not be met, and the accelerator core will not be damaged due to excessively high test temperature, and the measurement accuracy can be guaranteed.

[0034] In the present embodiment, the number of the watch movement mounting plates 4 is specifically four, and in actual situations, it can be specifically set according to the size of the heat preservation cover 3 and the watch movement tooling block 2.

[0035] The high-efficiency accelerometer core high temperature resistance initial testing device of this embodiment has a core mounting plate 4 capable of mounting a plurality of accelerometer cores 5 to be tested. During testing, the core mounting plate 4 can be replaced as a whole on the core tooling block 2 for testing, thereby reducing the time spent on installing and disassembling the accelerometer core on the core tooling block 2 during testing and improving the testing efficiency.

The test plate 41 is provided with a plurality of movement mounting holes 411 and a plurality of heat transfer holes 412, and the movement mounting holes 411 are used to mount the accelerometer movement 5.

[0037] Specifically, in this embodiment, the heat transfer holes 412 are multiple in one row, and the watch movement mounting holes 411 are multiple in two rows. The heat transfer holes 412 are located between the two rows of watch movement mounting holes 411, which can increase the heat transfer efficiency to the acceleration watch movement.

At the same time, the control module controls the sensor to work, collects the internal temperature of the thermal insulation cover 3, and sends the collected temperature signal to the display for display.

[0043] The high-efficiency accelerometer core high temperature resistance initial test device of this embodiment can prepare two sets of core mounting plates 4 in advance, and before the measurement of a batch of accelerometer cores installed on one set of core mounting plates 4 is completed, the other accelerometer cores 5 to be tested can be fixed to the other set of core mounting plates 4 in advance.
