Problems solved by technology
[0004] For this reason, both the L-shaped beam quality characteristic tooling and the frame tooling have shortcomings, especially the adjustment of the center of mass position, the measurement accuracy of the moment of inertia is not high, and the operation process is time-consuming and laborious. Improvement, replaced by a light-weight adjustable product quality characteristic measuring device to meet the needs of measuring and improving the measurement accuracy of the moment of inertia

Embodiment Construction
[0021] Such as figure 1 As shown, the light-duty adjustable product quality characteristic measuring device consists of an inner frame assembly 1, a rotation drive mechanism assembly 2, an outer frame assembly 3, a support column 4, a first rotation adjustment mechanism assembly 5, a lifting adjustment mechanism assembly 6, and a second rotation adjustment mechanism assembly. The mechanism assembly 7, the rotary joint mechanism 8, the product body 9 and the counterweight 10 are composed.
[0022] in such as figure 1 Among the inner frame assembly 1 and the outer frame assembly 3, the inner frame assembly 1 is composed of a polygonal frame, and the inner frame material is made of light carbon brazing material. The inner frame assembly is composed of eight frames connected by screws, and the inner frame assembly can adjust the polygonal side length arbitrarily according to the size of the product, so as to adapt to the use of products of different sizes. At the same time, the ...

Description
technical field [0001] The invention relates to a product quality characteristic measuring device, more specifically, relates to an adjustable product quality characteristic measuring device. Background technique [0002] At present, the test devices for measuring product quality characteristics at home and abroad mainly use: product quality characteristic test tooling (commonly known as L-beam), frame tooling, vertical tooling and other tooling combinations for testing. [0003] The measurement of the moment of inertia around the Z axis is realized by using vertical tooling, and the measurement of the moment of inertia around the X axis and the Y axis is realized by using a frame tooling plus an L-shaped beam quality characteristic tooling. After the rotating mechanism of the product quality characteristic testing tool is docked with the product, the rotation of the product on the L-shaped beam and the realization of various on-orbit attitude angles can be realized through ...
