Abstract
The invention relates to a machining method suitable for removing honeycomb cores at positions, ranging from 5 mm to 10 mm, of the edges of a honeycomb plate, and belongs to the technical field of composite material machining. All work is done on one horizontal working table, the posture of a flat edge trimmer is adjusted, it is guaranteed that a check ring of the flat edge trimmer is perpendicular to the horizontal working table, and the honeycomb plate is fixed to a specially-manufactured auxiliary horizontal tool; and the honeycomb cores are milled by horizontally moving the flat edge trimmer. According to the machining method, core removing is achieved through the handheld flat edge trimmer, the specially-manufactured auxiliary horizontal tool is used in a matched manner to position and clamp the honeycomb plate, and the honeycomb cores at the positions, ranging from 5 mm to 10 mm, of the edges of the honeycomb plate are removed.
Description
Technical field
The present invention relates to a kind of processing method being suitable for removing cellular board edge 5-10mm honeycomb core, belong to composites processing technology field.
Background technology
Composite cellular board has obtained abundant, extensive, a large amount of, ripe application at aerospace field, and the floor applications especially on medium or large passenger plane, transporter, occupies leading position especially, and in continuous ascendant trend.Cellular board not only has the feature of high specific strength, high specific stiffness, also has the features such as low-density, good combustion-supporting performance, excellent insulating properties and excellent corrosion resistance.Cellular board is by upper and lower panel, and therebetween honeycomb core combines, and honeycomb core periphery exposes, and for reducing environment to the corrosion of honeycomb core, design can require need remove 5-10mm honeycomb core at cellular board periphery, then stick with glue agent and carry out edge sealing.Because cellular board is all thinner, and can not excessively clamp, therefore general coring work can not adopt numerical control, machine adding method implements coring work.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of processing method being suitable for removing cellular board edge 5-10mm honeycomb core, by adopting Handheld edge trimming machine coring, be equipped with the method for special subsidiary level tool locating clamping cellular board the honeycomb core that cellular board edge 5-10mm measures is removed, quality, cost, efficiency are all taken into account, wherein cost is down to minimum, and can reach the designing requirement of product.
The present invention adopts following technical proposals to realize.A kind of processing method being suitable for removal cellular board edge 5-10mm honeycomb core, all working carries out on a horizontal table, the attitude of adjustment trimmer, guarantee that trimmer back-up ring is vertical with horizontal table, cellular board is fixed in special subsidiary level frock, require subsidiary level frock to be placed on horizontal table and will have certain steadiness, not easily promoted easily, honeycomb core milling is carried out by moving horizontally trimmer, milling depth is 5-10mm, honeycomb core thickness is not limit, there is the milling cutter mating diameter with honeycomb core, can disposable milling complete, do not mate milling cutter, cellular board needs turn-over to process at twice.
The present invention obtains application at present in the processing and manufacturing of aircraft honeycomb sandwich construction composite, and has achieved well processing and result of use.

Fig. 4 is schematic diagram after removal honeycomb core.
In figure: 1-backing plate, 2-trimmer, 3-milling cutter, 4-back-up ring, 5-glued membrane, 6-honeycomb core, 7-panel, 8-subsidiary level frock, 9-horizontal table, 10-cellular board.
Detailed description of the invention
Below in conjunction with Fig. 1,2,3,4, processing method of the present invention is described.
Concrete implementation step is as follows:
1, cellular board location
Cellular board-10 is clamped in special subsidiary level frock-8, needs cellular board-10 edge snap frock edge of coring.Cellular board-10 and subsidiary level frock-8 are placed on a horizontal table-9 in the lump.
2, trimmer location
Trimmer-2 is put on horizontal table-9, according to the difference in level of trimmer front end back-up ring-4 with trimmer rear end, by adding backing plate-1 in trimmer rear end and fixing mode, make the height of trimmer front end back-up ring-4 and trimmer rear end in same level.Trimmer milling cutter-3 height should higher than cellular board lower panel 0.5mm-1mm.
3, trimmer feeding depth adjustment
Milling cutter-3 exposes back-up ring 5mm-10mm, back-up ring is close to cellular board-10 and subsidiary level frock-8.
4, milling
Start trimmer-2, back-up ring-4 is close to cellular board-10 and subsidiary level frock-8 edge, and move on horizontal table-9 with certain speed promotion trimmer-2, first milling is close to the bonding honeycomb of subsidiary level frock-8 one faceplate panels-7 with cellular board-10, after processing, cellular board-10 turn-over, the honeycomb that processing another side is bonding with cellular board-10 panel-7.If honeycomb core-6 is highly less, have the milling cutter of optional diameter, this coring work can disposablely complete.
5, coring
With round spade, the honeycomb of milling is scooped up to other end from cellular board one end, honeycomb core is removed.If two multiple value of milling cutter diameter are greater than honeycomb core height, then after twice milling, honeycomb core is removed, does not need to carry out coring again.
