A device for composite material cover sinking

Abstract

The invention belongs to the field of composite material cover bodies, and particularly relates to a device for sinking of the composite material cover body. The device is composed of a pressing rod,a main body frame, a quick-release screw a, a push rod assembly, a quick release screw b, a cutter a, a cutter b, a quick release screw c and a sliding block, wherein a threaded hole is formed in themain body frame, the pressing rod is installed in the threaded hole of the main body frame and is screwed, the push rod assembly is placed in a positioning groove of the main body frame, a sliding groove is formed in the side face of the push rod assembly, and the sliding block is arranged in the sliding groove; the push rod assembly is fixed on the main frame through the quick release screw c, two cutter placing grooves which are perpendicular to each other are formed in the push rod assembly, the cutter placing groove of the cutter a is used for cutting the sinking width boundary of the cover body, and the cutter placing groove of the cutter b is used for cutting the sinking width and depth of the cover body; and the cutter a is fixed through the quick release screw b, and the cutter b is fixed through the quick-release screw a. The device has the advantages that the structure is simple, the operation is convenient, the application range is wide, and good quality benefits and economic benefits are obtained.

Description

technical field [0001] The invention belongs to the field of composite material covers. In particular, it relates to a device for repairing and subsidence of a composite material cover body. Background technique [0002] Many types of composite material covers such as LZ40H and LZ90A3 have sunken structures, which are used to connect with other composite material covers or aircraft skins, machine frames, etc.; the depth and width of the sinking directly affect the assembly steps and gaps The level of precision. [0003] Under the existing technical conditions, CNC machining is generally used for some small-sized composite material covers, but for larger-sized composite material covers such as LZ40H and LZ90A3, due to the limitation of the stroke of the CNC machine tool, it is impossible to perform CNC machining. The method of adding (LZ90A3 sinks on the side of the film surface, and cannot be added by machine). In this case, the subsidence of the synthetic material cover ...

AI Technical Summary

Problems solved by technology

Using the method of manually repairing the sag, the width and depth of the sag of the composite material cover are difficult to control. After connecting with other composite material covers or aircraft skins, machine frames, etc., the phenomenon of step difference and clearance is often caused.
