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...

Abstract

The invention provides a device for cleaning a blind hole of a composite material mould, and relates to the field of a technology for cleaning the blind hole of the mould, in particular to the technical field for cleaning the blind hole of the composite material mould. The device comprises a handheld part, a cylindrical rotating part connected with one end of the handheld part, and a groove which is formed on the cylindrical rotating part along the axis from the free end to the handheld part; the groove is used for clamping a flaky cleaning material used for cleaning the blind hole and enabling the flaky cleaning material to be wrapped and attached on the surface of the cylindrical rotating part. After the device is used, the assembly accuracy of a composite material part is guaranteed, and the damage to the inner wall of the blind hole can be reduced in the cleaning process of the blind hole of the composite material mould; furthermore, any electric tool is not used, and the cleaning cost of the blind hole of the composite material mould can be 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...
