Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an air compressor. Background Art

[0002] The aircraft engine is a highly complex and sophisticated thermal machine. As the heart of the aircraft, it is not only the driving force for the aircraft to fly, but also an important driving force for the development of aviation. Every important change in the history of human aviation is inseparable from the technological progress of aircraft engines. The compressor is a very important component of the aircraft engine, which is mainly responsible for compressing the air and delivering it to the combustion chamber. The blade structure is one of the important components of the compressor;

[0003] However, the existing compressor and the blade structure installed thereon are basically completely fixed. When the blade mechanism is damaged, it is necessary to repair it directly in the compressor. Due to limited space, maintenance is inconvenient and it is difficult to replace, and it does not change in use. For this reason, we propose a compressor. Utility Model Content

[0011] Preferably, a right wing knife is fixedly connected to a position near the center of the upper end of the end wall, and a notch is provided at the lower end of the end wall.

[0012] By adopting the above technical solution, the restriction of the first bolt on the fixing plate is cancelled by rotating the first bolt, and then the rotating wheel is rotated so that the rotating wheel, under the cooperation of the gear and the tooth block, drives the slide plate to slide downward inside the sliding box, so that the clamping block is separated from the installation box, and then the end wall is slid into the installation box, and then the rotating wheel is rotated again, and the clamping block is passed through the installation box through the cooperation of the slide plate, and inserted into the groove to fix the end wall, and then the first bolt is rotated again so that the first bolt restricts the fixing plate, and vice versa, so that the compressor can quickly load and unload the end wall, which is convenient for repairing and replacing the device above the end wall, and improves the replacement efficiency of the compressor;

[0013] By adopting the above technical scheme, the second bolt is rotated so that the fixation of the compressor blade by the second bolt disappears, and then the compressor blade is pulled out from the second bolt. After the compressor blade is replaced, the compressor blade is inserted into the fixing box, and then the second bolt is rotated to fix the compressor blade again. Moreover, through the cooperation of the right wing knife and the left wing knife, a certain pressure relief and turbulence effect is achieved on the secondary horseshoe vortex, thereby avoiding the formation of the secondary horseshoe vortex, and through the cooperation of the rotating drum and the third bolt, the angle of the left wing knife can be adjusted to a certain extent, thereby achieving different pressure relief and anti-flow effects according to the situation, so that the compressor can quickly replace the compressor blades, and the angle of the left wing knife can be adjusted to a certain extent, thereby improving the functionality of the compressor.

[0025] When in use, by rotating the first bolt 14, the restriction of the first bolt 14 on the fixing plate 13 is cancelled, and then the runner 12 is rotated to make the runner 12 drive the gear 10 to rotate through the fixing block 11. At this time, when the gear 10 rotates, it will drive the slide plate 8 to slide downward inside the sliding box 7 through the tooth block 9 on the right side of the slide plate 8. At this time, when the slide plate 8 slides, it will drive the connecting plate 15 and the block 16 to be fixed together, so that the block 16 is disengaged from the installation box 6, and then the end wall 17 is slid into the installation box 6, and then the runner 12 is rotated again, so that the block 16 passes through the installation box 6 and is inserted into the slot 25 to fix the end wall 17, and then the first bolt 14 is rotated again to restrict the fixing plate 13 by the first bolt 14.
