Description

Technical Field

[0001] The present invention relates to the field of launch technology, in particular to an automatic pitch and knock device for a composite material launch box and a cleaning method thereof. Background Art

[0002] In the aerospace, navigation, and other fields, domestic and international storage and transportation launch case products are primarily divided into metal launch cases and composite launch cases. Composite launch cases are increasingly used for launching aircraft. As a storage, transportation, and launch vehicle, launch cases must be free of any excess material, such as metal shavings, residual glue, or unnecessary fasteners, during final assembly and delivery acceptance.

[0003] At present, the cleaning of excess materials in domestic launch boxes mainly relies on personnel entering the narrow and long launch box for cleaning, or manually knocking on the load-bearing parts such as the metal support frame outside the launch box, or using a crane to lift and tilt the launch box to shake off and remove the excess materials. There are problems such as high labor intensity, small operating space in the box, low efficiency of excess material cleaning, and poor consistency of excess material cleaning. The above-mentioned process methods have the disadvantages of inconsistent knocking force and uneven knocking frequency, as well as hidden dangers such as excessive unilateral knocking force damaging the composite material box and improper operation causing accidental damage to the composite material box, all of which have potential adverse effects on the quality of the composite material box of the launch box.
