The fixing hole of one correspondence, described fixing hole is blind hole, described head and described afterbody utilize securing member pass through second step hole and
Fixing hole is fixed.
Preferably, the end of described head has concave character type connecting portion and cannelure, has sealing gasket in described cannelure
Circle, 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 this utility model is reached:
Main shaft of the present utility model grinds mainly for the inner circle with taper knife handle, it is possible to increase working (machining) efficiency and processing essence
Degree.In order to convenient is processed manufacture to main shaft, main shaft is set to dismountable head and afterbody；

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for this is clearly described
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
As Figure 1-4, a kind of grinding machine inner circle grinds main shaft, including dismountable head and afterbody, the center tool of head
Having taper installing hole 11, afterbody 2 center to have the first step hole 21 coaxial with taper installing hole 11, it is right that such design is easy to
Head with taper installing hole 11 is processed, and 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,
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, head
Portion 1 and afterbody 2 utilize securing member 3, such as screw, are fixed by second step hole 12 and fixing hole 22.Also there is outside afterbody 2 key
Groove.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, afterbody 2 in cannelure 13
Front end there is 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 preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and deformation, these change
