Disclosure of Invention
The invention provides a clamping device for an environment test of a gas generator, which aims to improve the environment test efficiency of the gas generator, save cost and reduce potential safety hazards. The nine-engine gas generator is clamped on the bottom plate through a pressing ring, and the pressing ring is tightly connected with the bottom plate through a fastening bolt. Each hole site on the bottom plate (including layer board, right side board, lower plate) is connected with corresponding test equipment. The fuel gas generator and the bottom plate only need to be installed and clamped once, repeated assembly and disassembly are not needed, and the environmental test requirements in all directions can be met by converting the installation mode of the bottom plate and the test equipment.
The realization process of the invention is as follows:
the invention discloses a clamping device for an environment test of a fuel gas generator, which consists of a bottom plate, a pressure ring, a fastening bolt and the fuel gas generator. Nine fuel gas generators are fixed on the bottom plate through the pressure ring, and the bottom plate is connected with the pressure ring through the fastening bolt. The bottom plate is formed by welding a supporting plate, a right side plate, a lower side plate and a reinforcing rib plate into a whole. Each hole site of the bottom plate corresponds to the position of the connecting hole site of the environmental test equipment.
The invention has the following advantages:
the nine-engine gas generator and the bottom plate are only required to be fastened and connected once, and are not required to be mounted, clamped and dismounted for multiple times, and vibration tests, impact tests and acceleration tests with specific direction requirements can be completed only by changing the mounting mode of the bottom plate and the test equipment.

Detailed Description
The invention is further illustrated with reference to the following figures and examples.
Example 1
The intended gasifier orientation is shown in fig. 1. The required test directions for each environmental test are shown in table 1. The requirements of the impact test direction are X +, the vibration test direction is Y and Z, and the acceleration test direction is X +/-minus or plus, Y +/-plus or minus and Z +/-are known.
The environmental test apparatus used was a bench top as shown in FIG. 2. And the hole sites on each table top are threaded holes for mounting and fixing the test device. The hole sites on the test device need to correspond to the hole sites on the test equipment table during installation.
As shown in fig. 3, a gasifier environmental test card loading device comprises: 1-bottom plate, 2-press ring, 3, fastening bolt, 4-gas generator. The nine-engine gas generator is fixed on a bottom plate 1 through a pressing ring 2, and the bottom plate 1 is connected with the pressing ring 2 through a fastening bolt 3. The bottom plate 1 is formed by welding a supporting plate, a right side plate, a lower side plate and a reinforcing rib plate into a whole. The reinforcing rib plate is used for fixing the supporting plate and the lower side plate.
The hole site design and function on the bottom plate of the card loading device is shown in fig. 4. The bottom plate is formed by welding a supporting plate, a right side plate, a lower side plate and a reinforcing rib plate, and can be fixedly connected with the vibration table, the impact table and the acceleration table through corresponding hole positions on the supporting plate, the right side plate and the lower side plate, and meanwhile, the test direction of the gas generator can be quickly changed.
The mounting mode of the gas generator environment test card installing device and the test equipment table surface when various environment tests are carried out is shown in figure 5. The gas generator and the clamping device are integrated, repeated disassembly is not needed, and the requirements of all tests and directions can be met only by changing the mounting mode of the gas generator and the test bed through the connecting holes. The invalid operation time in the test is greatly reduced, the potential safety hazard is reduced, and the environmental test efficiency is improved.
When carrying out Z to vibration test, through corresponding hole site and shaking table fastening connection on the layer board, when carrying out Y to vibration test, through corresponding hole site and shaking table fastening connection on the right side board, when carrying out X + direction impact test, through corresponding hole site and the impact table fastening connection on the lower side board, when carrying out X direction acceleration test, through corresponding hole site and the acceleration table fastening connection on the right side board, when carrying out Y direction, Z direction acceleration test, through corresponding hole site and the acceleration table fastening connection on the lower side board.
By adopting the invention, the environmental test examination of the gas generator in the batch production trial production process can be efficiently, quickly and safely carried out.
The above embodiments are only for illustrating the invention and are not to be construed as limiting the invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention, therefore, all equivalent technical solutions also belong to the scope of the invention, and the scope of the invention is defined by the claims.
