The collection tank 29 can be cylindrical in shape matching the size of the through hole to prevent waste chips from entering the gap between the collection tank 29 and the side wall of the through hole.

[0021] The working principle of the auxiliary assembly device for aerospace parts provided by the present technical solution is as follows: first, place the nut to be assembled in the nut groove, place the shaft 19 to be assembled on the clamping mechanism, and then lower the clamping mechanism to drive the shaft to be assembled to descend, and at the same time drive the push-pull plate 6 to move downward, thereby driving the annular piston 5 to move downward to push the gas in the outer ring chamber 23 to flow to the inner ring chamber 24 through the gas delivery hole 31, and then be discharged from the exhaust pipe 4 to flow to the nut groove, so that the air in the nut groove flows to blow and clean the nut groove. When the shaft 19 to be assembled continues to descend and is inserted into the nut to be assembled for assembly, the annular piston 5 continues to descend synchronously to blow air into the nut groove, thereby blowing out the waste chips generated during the assembly of the shaft and the nut out of the nut groove. , the blown waste chips or dust fall into the collecting tank 29 through the leakage hole or the mesh on the support frame 22; after the shaft and nut are assembled, the clamping mechanism is moved upward, driving the push-pull plate 6 to move upward, and then driving the annular piston 5 to move upward. At this time, negative pressure is generated in the outer ring chamber 23, the inner ring chamber 24, and the air inlet pipe 28. Under the action of the external air pressure, the external gas enters the inner ring chamber 24 from the air inlet pipe 28 and enters the outer ring chamber 23 through the air delivery hole 31, so that the air pressure inside and outside the support body 3 remains balanced. At the same time, the gas around the air inlet end of the air inlet pipe 28, including the gas at the nut groove above it, is disturbed, thereby disturbing the waste chips left at the nut groove, causing the waste chips to enter the collecting tank 29 from the leakage hole, thereby realizing further collection of the waste chips.

At the same time, the gas around the air inlet end of the air inlet pipe 28, including the gas at the nut groove above it, is disturbed, thereby disturbing the waste chips left at the nut groove, causing the waste chips to enter the collecting tank 29 from the leakage hole, so as to further collect the waste chips. That is, the present invention exhausts air through the exhaust pipe 4 and inhales air through the air inlet pipe 28, so that a downward airflow is generated at the nut groove, blowing away the waste chips generated during assembly, and the waste chips enter the collecting tank 29 through the mesh holes and the leakage holes to complete the collection, so as to avoid the waste chips affecting the assembly accuracy of the next assembly part; the air inlet end of the air inlet pipe 28 is detachably provided with a filter screen 27 to isolate the waste chips and prevent the air inlet pipe 28 from being blocked.
