Description

Technical Field

[0001] The utility model relates to the technical field of composite material manufacturing, in particular to a honeycomb sandwich panel inlay installation workbench. Background Art

[0002] Composite honeycomb sandwich panels are composed of upper and lower fiberboards and a honeycomb core. The honeycomb core and the fiberboards are bonded together by adhesive film. This type of honeycomb sandwich structure composite material is light, high in rigidity, corrosion-resistant and flame-retardant. It also has certain vibration and wave absorption functions, and has certain applications in aerospace and satellite antennas. Among them, the passenger and cargo compartment floors of various large passenger aircraft also mostly use sandwich panels of this type of structure.

[0003] Before composite honeycomb sandwich panels are processed into passenger and cargo compartment floors, in addition to being processed in shape according to the digital model of the passenger and cargo compartment floor products, they also need to be edge-sealed around the perimeter and inlaid with parts at the connection between the passenger and cargo compartment floor and the floor beams to prevent the honeycomb core inside the floor from getting damp and damaged, and to ensure that the entire floor can be installed, fixed and withstand a certain amount of force.

[0007] In the present invention, the height and diameter of the guide column on the limit block, the height h of the three bosses, and the distance from the guide column axis are designed according to the outer contour diameter of the inlay installed on the honeycomb sandwich panel, the diameter of the middle through hole, and the overall height. It is required that the three bosses are at equal distances from the guide column on the side close to the guide column surface, and on the basis of ensuring sufficient support for the inlay, the base is subjected to a certain surface reduction treatment to reduce the contact area with the inlay, which is conducive to visual inspection of the contact between the inlay and the base, and ultimately achieves the design requirement that the protrusion of the inlay from the upper surface of the honeycomb sandwich panel is not greater than the height h of the boss.

[0008] In the utility model, a supporting foot is installed at the bottom of the supporting leg.

[0009] In the present invention, the three bosses are arranged in a Y shape.

[0010] In the utility model, a storage box for storing the main line of the automatic telescopic wire take-up device is provided on the reinforcement baffle.

[0011] In this utility model, the specific use is as follows:

[0012] Place the honeycomb sandwich panel with the completed inlay installation hole processing on the table, with the upper surface of the honeycomb sandwich panel facing downward, that is, the upper surface of the honeycomb sandwich panel is placed in contact with the table, and then place the inlay into the inlay installation hole, with the side of the inlay with the glue injection hole facing upward. Then, starting from one side of the honeycomb sandwich panel, use limit blocks to position the side of each inlay without the glue injection hole. When positioning, according to the position and number of the inlays, a certain number of limit blocks are pulled out of the automatic telescopic take-up at the corresponding position to a certain length for easy operation, and finally ensure that the height of the inlay protruding from the upper surface of the honeycomb sandwich panel does not exceed h. Use limit blocks to position the inlay on the table. After the adhesive gels, lift the honeycomb sandwich panel as a whole, use the automatic telescopic take-up to retract the limit blocks, and keep the limit blocks clean.

[0013] Beneficial effects: The utility model utilizes an automatic telescopic take-up device and a limit block to complete the installation of inlays on the honeycomb core sandwich panel, so as to ensure that the amount of the inlays protruding from the upper surface of the floor after installation meets the design requirements, thereby effectively improving the installation efficiency; it has been applied in the processing of passenger and cargo cabin floor panels with honeycomb sandwich structures of large passenger aircraft, and has achieved good processing results.
