Abstract
The utility model discloses a face milling cutter connection structure, relates to the field of a machining cutter, and provides a face milling cutter connection structure which is convenient to assemble. The face milling cutter connection structure comprises a face milling cutter and a positioning mandrel, wherein a positioning hole is formed in the face milling cutter, the positioning mandrel is inserted into the positioning hole, the outer side of the positioning hole in the face milling cutter is provided with a guide hole which is coaxial with the positioning hole, and the diameter of the guide hole is greater than that of the positioning hole. Through the guide hole, a gap between the guide hole and the positioning mandrel is large, and thus the positioning mandrel is easily installed in the guide hole. After the positioning mandrel is installed in the guide hole, the swinging of the positioning mandrel can be prevented by the guide hole, so that the positioning mandrel is conveniently installed in the positioning hole, and the face milling cutter connection structure is particularly applicable to the situation that the gap between the positioning hole and the positioning mandrel is small.
Description
Technical field
The utility model relates to machine tool field, relates in particular to a kind of face milling cutters syndeton.
Background technology
The locating core axis hole of existing index plane milling cutter interface is a straight hole that precision is H7.The positioning cylinder that this locating core axis hole is h7 with a precision is connected cooperation, reaches high-precision location, guarantees the normal use of face milling cutters.But in actual use, milling cutter mostly is multiple tooth cutting tool, and mating holes and the shaft clearance of H7/h7 are larger, and the Accuracy of therefore cutter circumference being beated is very large, in the time of limit tolerance to cutter circumference jumping effect at 0.12mm～0.072mm, affected greatly life-span and the use etc. of cutter.And while changing aperture and shaft clearance, install inconveniently because most of milling cutter weight causes more greatly, and and overexert and can damage, scratch location basal plane, even pull out burr, thereby make precision lose the use that has had influence on cutter.
Utility model content
The technical problems to be solved in the utility model is: a kind of face milling cutters syndeton of being convenient to assembling is provided.
For the technical scheme that addresses the above problem employing is: face milling cutters syndeton comprises face milling cutters and positioning core axle, face milling cutters inside is provided with locating hole, positioning core axle inserts locating hole, the inherent locating hole arranged outside of face milling cutters has the pilot hole coaxial with locating hole, and the diameter of pilot hole is greater than the diameter of locating hole.
Further: locating hole dimensional tolerance is H6, pilot hole dimensional tolerance is F7, and positioning core axle dimensional tolerance is h6.
Further: the pilot hole degree of depth is 3-5mm.
The beneficial effects of the utility model are: be provided with pilot hole, pilot hole and positioning core axle gap are larger, and it is easy that positioning core axle packs pilot hole into.Positioning core axle packs into after pilot hole, pilot hole prevent positioning core axle swing, pack locating hole into thereby be convenient to positioning core axle, be particularly useful for locating hole and positioning core axle gap compared with hour.
Brief description of the drawings
Fig. 1 is face milling cutters syndeton cutaway view;
In figure, be labeled as: pilot hole 1, locating hole 2, positioning core axle 3, face milling cutters 4.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Face milling cutters syndeton comprises face milling cutters 4 and positioning core axle 3, face milling cutters 4 inside are provided with locating hole 2, positioning core axle 3 inserts locating hole 2, and inherent locating hole 2 arranged outside of face milling cutters 4 have the pilot hole 1 coaxial with locating hole 2, and the diameter of pilot hole 1 is greater than the diameter of locating hole 2.
Pilot hole 1 is larger with positioning core axle 3 gaps, and it is easy that positioning core axle 3 packs pilot hole 1 into.Positioning core axle 3 packs into after pilot hole 1, and pilot hole 1 prevents that positioning core axle 3 from swinging, and packs locating hole 2 into thereby be convenient to positioning core axle 3, is particularly useful for locating hole 1 and positioning core axle 3 gaps hour.
Connect precision in order to improve face milling cutters syndeton, locating hole dimensional tolerance is H6, and pilot hole dimensional tolerance is F7, and positioning core axle dimensional tolerance is h6.In the situation that basic deviation is constant, improve the grade of tolerance of locating hole 2 and positioning core axle 3, the limit deviation (locating hole is of a size of upper limit while positioning core axle and is of a size of down in limited time) of locating hole 2 and positioning core axle 3 sizes reduces greatly, cutter circumference is beated and is reduced, and has reached technically the life-span and the machining accuracy texts that improve cutter.Although the grade of tolerance has improved one-level, completely no problem in 6 grades of tolerances of existing processing.
For easy to assembly, should require the surface roughness of locating hole 2 and positioning core axle 3 to be not more than Ra0.8 pilot hole 1 surface roughness and require lowlyer can be not more than Ra1.6.
Pilot hole 1 should be too not shallow, and too shallow guiding (preventing that positioning core axle 3 from swinging) effect is bad; Pilot hole 1 should be too not dark yet, too deeply reduces locating hole 2 degree of depth, is unfavorable for location.It is 3-5mm that the utility model is recommended pilot hole 1 degree of depth, takes into account pilot hole 1 guide effect and locating hole 2 locating effects.
Claims (3)
