The utility model aim is to overcome the deficiencies of the prior art and provide a kind of honeycomb sandwich panel boring core tool.
The technical problem solved by the utility model is implemented by the following technical solutions:
The lower pole of a kind of honeycomb sandwich panel boring core tool, including knife bar and cylindrical type milling cutter, knife bar is equipped with cylinder with it
Type milling cutter, the radius of clean-up of cylindrical type milling cutter is depending on the boring core depth of honeycomb sandwich panel；It is located at cylinder on knife bar shaft
The upper and lower position of type milling cutter is respectively equipped with positioning splint and lower positioning splint, is formed between upper positioning splint and lower positioning splint
The located space of honeycomb sandwich panel.
Further, upper positioning splint is identical as the structure of lower positioning splint, and upper positioning splint includes circular base, in circle
The centre of matrix is equipped with knife bar via hole, protruding upward equipped with hollow with externally threaded cylinder, cylinder around the periphery of knife bar via hole
The body spiro of body is connected to nut.
Further, the cylinder is imperfect cylinder, and cylinder is made of four round petals.
The utility model structure is simple, can operate it is strong, compared with prior art, accurately control honeycomb boring core width and
Depth, the careless slightly risk for causing to scrap with regard to injuring part, greatly improves honeycomb sandwich panel when avoiding manual processing
The processing quality and processing efficiency of boring core.

Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Embodiment 1, referring to Fig. 1 --- a kind of honeycomb sandwich panel boring core tool shown in fig. 6, including knife bar 1 and cylindrical type
The blade type of milling cutter 2, the generally hard alloy material of cylindrical type milling cutter 2, cylindrical type milling cutter 2 can be excellent according to cellular material selection
It is selected as cylinder " pineapple " type milling cutter, cylindrical type milling cutter 2, the radius of clean-up root of cylindrical type milling cutter 2 are equipped with the lower pole of knife bar 1
Depending on the boring core depth of honeycomb sandwich panel, in this way when knife bar encounters the edge of the upper and lower plate of honeycomb sandwich panel, cutter can not
Milling is deeper, and cellular boring core depth meets processing request at this time, and the upper bottom of cylindrical type milling cutter 2 is located on 1 shaft of knife bar
It sets and is respectively equipped with positioning splint 3 and lower positioning splint 4, form honeycomb sandwich panel between upper positioning splint 3 and lower positioning splint 4
Located space.
Further, upper positioning splint 3 is identical as the structure of lower positioning splint 4, and upper positioning splint 3 includes circular base 31,
It is equipped with knife bar via hole in the centre of circular base 31, it is protruding upward equipped with hollow with externally threaded around the periphery of knife bar via hole
Cylinder 32, the body spiro of cylinder 32 are connected to nut 5, and nut 5 can be hex nut 5, in order to facilitate the operation of butterfly is also replaced by
Shape nut.
Further, the cylinder 32 is imperfect cylinder 32, and cylinder 32 is made of four round petals.
A kind of boring core method of honeycomb sandwich panel, it includes the following steps:
The first step adjusts one of positioning splint at a distance from cylindrical type milling cutter 2, and the distance is made to be equal to honeycomb sandwich panel
The thickness of single side plate, tightening nut are locked at the positioning splint on knife bar,
Second step adjusts another piece of positioning splint, and the one side for the cylinder 32 for deviating from the positioning splint is bonded another piece of list
The outer surface of panel material, and tightening nut are locked at the positioning splint equally on knife bar,
The knife handle of 1 upper end of knife bar is clamped on hand-held pneumatic drill by third step, and opening pneumatic drill can start to carry out honeycomb boring
Core.
