Description
Technical field
The utility model relates to the cutter holder field of rotating cutting tool, is specially a kind of for cutting tool and the rigidly connected handle of a knife of rotating shaft.
Background technology
Common equipment when stock-removing machine is machining, during use, cutting tool is connected with the rotating shaft of stock-removing machine by handle of a knife, and rotating shaft carry its tools rotates to implement machining to workpiece.The smooth enforcement of connection to machining of visible cutting tool and stock-removing machine main shaft plays an important role.But at present for the handle of a knife parts that cutter is connected with rotating shaft, poor rigidity when also there is connection, transmission is unstable, positioning precision is low, tool changing operation is loaded down with trivial details, baroque defect, have impact on the smooth operation of machining.
Utility model content
In order to overcome the defect of prior art, providing that a kind of structure is simple, easily manufactured, rigidity is large, stable transmission, replacing is convenient, precision is high cutter cutter holder, the utility model discloses a kind of for cutting tool and the rigidly connected handle of a knife of rotating shaft.
The utility model reaches goal of the invention by following technical solution:
One is used for cutting tool and the rigidly connected handle of a knife of rotating shaft, comprises the cutter hub for fixing cutting tip, it is characterized in that: also comprise branch sleeve and screw,
The front end of cutter hub is blade clamp body, and the rear end of cutter hub is clamping part, and blade clamp body and the central axis both clamping part overlap mutually and as the central axis of cutter hub;
The center of clamping part rear end face has screw, described screw is blind hole, the lateral surface of clamping part cuts out parallel to each other and and two locating surfaces of clamping part centerline axis parallel, namely on the cross section of clamping part, locating surface is as two strings parallel to each other on clamping part cross section;
The center of branch sleeve front end face has blind hole, and the blind hole of branch sleeve and the outer rim of clamping part match each other; The center of branch sleeve rear end face has screw, the screw of branch sleeve and the blind hole of branch sleeve through;
Cutter hub clamping part is enclosed within the blind hole of branch sleeve, and screw screws in the screw of clamping part rear end face again after the screw of branch sleeve rear end face penetrates, and the front end face of branch sleeve props up the rear end face of cutter hub blade clamp body.
Described for cutting tool and the rigidly connected handle of a knife of rotating shaft, it is characterized in that: on the cross section of cutter hub clamping part, locating surface is as two strings parallel to each other on clamping part cross section, and the action of described string is 1/3 ~ 1/2 of clamping part thickness;
The nominal diameter of clamping part screw is 1/2 of clamping part external diameter.
When the utility model uses, the blade clamp body of cutter hub is used for fixing cutting insert, and branch sleeve is fixed on lathe, cutter hub and branch sleeve is connected and fixed by screw, thus cutter hub is fixed on lathe, achieve being rigidly connected rotating shaft and cutter and transmission.
The utility model tool has the following advantages:
1. achieve being rigidly connected of handle of a knife and main shaft, strained by internal thread, carry out transmission by locating slot, meet the rigid demand of cutter when High Rotation Speed;
2. have higher repetitive positioning accuracy, cutter need not self-locking, changes cutter rapidly convenient;
3. simply, cost of manufacture is low, and the life-span is long for handle of a knife and main axle structure.
The beneficial effects of the utility model are: structure is simple, easily manufactured, and rigidity is large, stable transmission, and it is convenient to change, and precision is high, long service life.

Detailed description of the invention
The utility model is further illustrated below by way of specific embodiment.
Embodiment 1
A kind of be used for cutting tool and the rigidly connected handle of a knife of rotating shaft, comprise for the cutter hub 1 of fixing cutting tip, branch sleeve 2 and screw 3, as shown in Figure 1 to 4, concrete structure is:
The front end of cutter hub 1 is blade clamp body 11, and the rear end of cutter hub 1 is clamping part 12, and blade clamp body 11 and the central axis both clamping part 12 overlap mutually and as the central axis of cutter hub 1;
The center of clamping part 12 rear end face has screw, described screw is blind hole, the lateral surface of clamping part 12 cuts out parallel to each other and and two locating surfaces 13 of clamping part 12 centerline axis parallel, namely, on the cross section of clamping part 12, locating surface 13 is as two strings parallel to each other on clamping part 12 cross section;
As shown in Figure 3 and Figure 4, the center of branch sleeve 2 front end face has blind hole to branch sleeve 2, and the blind hole of branch sleeve 2 and the outer rim of clamping part 12 match each other; The center of branch sleeve 3 rear end face has screw, the screw of branch sleeve 2 and the blind hole of branch sleeve 2 through;
Cutter hub 1 clamping part 12 is enclosed within the blind hole of branch sleeve 2, and screw 3 screws in the screw of clamping part 12 rear end face again after the screw of branch sleeve 2 rear end face penetrates, and the front end face of branch sleeve 2 props up the rear end face of cutter hub 1 blade clamp body 11.
On the cross section of cutter hub 1 clamping part 12, locating surface 21 is as two strings parallel to each other on clamping part 2 cross section, and the action (value of action is the difference of radius of circle and distance from the chord to the centre) of described string is 1/3 ~ 1/2 of clamping part 12 thickness, and the present embodiment gets 1/2; The nominal diameter of clamping part 12 screw is 1/2 of clamping part 2 external diameter.
When the present embodiment uses, the blade clamp body 11 of cutter hub 1 is for fixing cutting insert, and branch sleeve 2 is fixed on lathe, cutter hub 1 and branch sleeve 2 is connected and fixed by screw 3, thus cutter hub 1 is fixed on lathe, achieve being rigidly connected rotating shaft and cutter and transmission.
