Technical field
The present invention relates to a kind of internal grinder main shaft, be specifically related to a kind of handle of a knife inner circle mill main shaft.
Background technology
Internal grinder is a kind of for processing the cylinder of workpiece, cone or the bore area of other shape element line generateds and the grinding machine of end face thereof.Grinding machine spindle of the prior art is typically difficult to meet the requirement that metal surface is good, dimensional accuracy is high, particularly to handle of a knife, such as the grinding of the bore area of BT50 handle of a knife, is therefore badly in need of a kind of being specifically designed for the internal grinder main shaft with taper knife handle.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of grinding machine inner circle and grinds main shaft, and this main shaft grinds mainly for the inner circle with taper knife handle, it is possible to increase working (machining) efficiency and machining accuracy.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of grinding machine inner circle grinds main shaft, including dismountable head and afterbody, the center of described head has taper installing hole, described afterbody center has the first step hole coaxial with taper installing hole, the taper installing hole periphery of described head is circumferentially all provided with some second step holes, second step hole is through hole, the front end of described afterbody is provided with and described second step hole fixing hole one to one, described fixing hole is blind hole, and described head and described afterbody utilize securing member to be fixed by second step hole and fixing hole.
Preferably, the end of described head has concave character type connecting portion and cannelure, has seal washer in described cannelure, and the front end of described afterbody has the convex connecting portion that described concave character type connecting portion matches.
Preferably, inside main shaft, grinding core shape handle of a knife, pull head, pulling claw, pull bar and butterfly spring are treated in installation the most successively.
Preferably, the taper installing hole periphery of described head is circumferentially all provided with six second step holes.
Preferably, described securing member is screw class securing member.
Preferably, described lateral tail also has keyway.
Preferably, the vertical diameter in described second step hole is followed successively by: 51mm, 40mm, 30mm, 50mm.
The beneficial effect that the present invention is reached:
The main shaft of the present invention grinds mainly for the inner circle with taper knife handle, it is possible to increase working (machining) efficiency and machining accuracy.In order to convenient is processed manufacture to main shaft, main shaft is set to dismountable head and afterbody；
First step hole can be used for installing location, it is simple to the installation of screw, also can increase the intensity of head simultaneously.
Accompanying drawing explanation

Fig. 2 is the front view of spindle nose in Fig. 1；
Fig. 3 is main shaft tail side sectional view in preferred embodiment；
Sectional view after Fig. 4 Fig. 1 and Fig. 3 installation；
Fig. 5 is equipped with the main shaft side sectional view of handle of a knife and pull head, pulling claw, pull bar and butterfly spring；Wherein:
1. head, 11. taper installing holes, 12. second step holes, 13. cannelures, 14. concave character type connecting portions, 2. afterbody, 21. first step holes, 21. first step holes, 22. fixing holes, 23. convex connecting portions, 3. securing member, 4. treats grinding core shape handle of a knife, 5. pull head, 6. pulling claw, 7. pull bar.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
As Figure 1-4, a kind of grinding machine inner circle grinds main shaft, including dismountable head and afterbody, the center of head has taper installing hole 11, afterbody 2 center has the first step hole 21 coaxial with taper installing hole 11, such design is easy to be processed the head with taper installing hole 11, reduces the difficulty of processing of whole main shaft.
Taper installing hole 11 periphery of head 1 is circumferentially all provided with six second step holes 12, and second step hole 12 is through hole, and the vertical diameter in second step hole 12 is followed successively by: 51mm, 40mm, 30mm, 50mm.
The front end of afterbody 2 is provided with and fixing hole 22 one to one, described second step hole 12, and fixing hole 22 is blind hole, and head 1 and afterbody 2 utilize securing member 3, such as screw, is fixed by second step hole 12 and fixing hole 22.Also there is outside afterbody 2 keyway.This keyway is used for connecting the rotating mechanism being positioned at outside main shaft.
The end of head 1 has concave character type connecting portion 14 and cannelure 13, has seal washer in cannelure 13, and the front end of afterbody 2 has the convex connecting portion 23 that described concave character type connecting portion 14 matches.
Install the most successively inside main shaft and treat grinding core shape handle of a knife 4, pull head 5, pulling claw 6, pull bar 7 and butterfly spring.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, on the premise of without departing from the technology of the present invention principle; can also make some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention.
