Problems solved by technology
Usually, the residual glue on the inner wall of the blind hole on the composite molding die is cleaned using a pneumatic drill. Although the pneumatic drill has high cleaning efficiency, it is difficult to control due to its high speed and large cutting force, and it is easy to damage the inner wall of the blind hole, resulting in the failure of composite parts. Reduced assembly accuracy

Embodiment Construction
[0010] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0011] The composite mold blind hole cleaning device of the present invention has been successfully applied in the manufacture of a flat tail composite material part of a certain type of helicopter. Layer and glue coating, resulting in residual glue on the inner wall of the blind hole of the composite material forming mold, which needs to be cleaned. There are 3 φ10mm positioning holes and 3 φ10mm detection holes on the FRP forming mold. The depth of these 6 blind holes 20mm. Usually, the residual glue on the inner wall of the blind hole on the composite molding die is cleaned using a φ10mm pneumatic drill. The high speed of the pneumatic drill and the large cutting force are difficult to control, resulting in the frequent cutting of the inner wall of the blind hole, so that the φ10mm positioning hole and detection hole Deformation, affecting t...

The invention discloses a cleaning device for blind holes of composite dies and relates to the technical field of cleaning of die blind holes, in particular to cleaning of blinds holes of composite dies. The cleaning device is composed of a handheld part, a cylindrical rotary part and a groove, wherein the cylindrical rotary part is connected with one end of the handheld part, and the groove is arranged along the axis of the cylindrical rotary part from a free end to the handheld part on the cylindrical rotary part, the groove is used for clamping sheet type cleaning materials for cleaning the blind holes and wrapping the sheet type cleaning materials onto the surface of the cylindrical rotary part. By the aid of the cleaning device, assembly accuracy of composite parts is guaranteed, damage to the inner walls of the blind holes during cleaning of the blind holes of the composite dies is reduced, and since no electric tools are used, cost for cleaning the blind holes of the composite dies is reduced.
Description
technical field [0001] The invention relates to the technical field of cleaning blind holes of molds, in particular to the technical field of cleaning blind holes of composite material molds. Background technique [0002] With the development of composite material technology, the amount of composite materials used on aircraft is increasing continuously. At the same time, the assembly accuracy requirements of composite material parts are also getting higher and higher, and the assembly accuracy of composite material The accuracy of the blind hole on the mold is guaranteed. Due to the particularity of composite material molding, that is, multiple layers and glue application are required during the molding process, resulting in residual glue on the inner wall of the blind hole of the composite material molding mold, which needs to be cleaned. Usually, the residual glue on the inner wall of the blind hole on the composite molding die is cleaned using a pneumatic drill. Although...
