Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
The main folder head body device of the present invention, as Figure 1-3, including the main collet body 2 of hollow, described main collet body 2
Mid portion is provided with the flange face 21 extended radially inward, and broaching tool 1 inserts from one end of main collet body 2 and is held on described flange
The side in face 21, connecting rod 3 inserts the opposite side being held on described flange face 21 from the other end of main collet body 2, described in draw
Cutter 1 and connecting rod 3 all parts are stretched out and are positioned at outside described main collet body 2.The main collet body 2 of described flange face 21 opposite side
Sidewall be provided with at least one perforate 22 radially extended along main collet body 2, described perforate 22 is near described main folder head
The junction of body 2 and connecting rod 3, described perforate 22 exposes described connecting rod 3, and described connecting rod 3 is relative with described perforate 22
The position answered is provided with the groove 31 radially extended internally, contiguous block 32 from the sidewall of described main collet body 2 to interpolation
Enter to be positioned at described groove 31 and perforate 22, therefore block described connecting rod 3 and main collet body 2 so that connecting rod 3 will not
Drop out from the other end of main collet body 2, the described connecting rod 3 of fixing connection and main collet body 2.
The other end of described connecting rod 3 is exposed to described main collet body 2 and is inserted into base of the carrier head 4 from side, its another
End is exposed to the opposite side of described base of the carrier head 4, and is cased with packing ring 41 and nut 42 on this other end by connecting rod 3 and chuck
Seat 4 is fixedly connected, and described main collet body 2 is just held on outside the side of described base of the carrier head 4, so can be by main collet body 2
It is fixed on described base of the carrier head 4.
At least one it is additionally provided with along main collet body 2 through hole 23 radially on the sidewall of the main collet body 2 of described flange face 21 side
It is communicated on described broaching tool 1, and the lateral wall of the main collet body 2 of the side of described through hole 23, as shown is through hole 23
Lower section main collet body 2 lateral wall on, be provided with one along main collet body 2 radially extend and with described through hole 23 even
Logical recess 24, the size of fixture block 5 matches with described through hole 23 and recess 24 and is positioned at described recess 24 and through hole
In 23, described broaching tool 1 position corresponding with described through hole 23 is provided with the fixture block recess 11 matched with through hole 23, described
Fixture block 5 is inwardly inserted into from through hole 23 and is stuck in described fixture block recess 11 and through hole 23, with fixing described broaching tool 1 and main collet body
2.And the part of described fixture block 5 is positioned at through hole 23, another part is positioned at recess 24, described recess 24 and described card
Being additionally provided with spring 6 between block 5, described spring 6 makes fixture block 5 the most outwards have and emerges in becoming of described fixture block recess 11
Gesture, and then make described fixture block unclamp described broaching tool 1 and main collet body 2 the most all the time.
One sliding sleeve 7 is placed on the outside of described main collet body 2, and the internal diameter of this sliding sleeve 7 matches with the external diameter of main collet body 2, because of
This compresses fixture block 5 and contiguous block 32 in lateral so that main collet body 2 interfixes more with broaching tool 1 and connecting rod 3
Add firmly.
And described sliding sleeve 7 extenal fixation has a rotary sleeve 8, the rotation of this rotary sleeve 8 can drive and slide over outside main collet body 2
Rotating, position corresponding with described fixture block 5 on the inner surface of described rotary sleeve 8 is provided with sliding sleeve recess 71 radially,
The most described fixture block 5 and described sliding sleeve recess 71 are positioned at the described the most same height of main collet body 2, when sliding sleeve 7 rotates to fixture block 5
When described sliding sleeve recess 71, described fixture block 5 can move out under the effect of spring 6 and emerge in described fixture block recess 11,
And then unclamp main collet body 2 and broaching tool 1, and when sliding sleeve 7 rotation makes fixture block 5 emerge in sliding sleeve recess 71, described fixture block 5
Broaching tool 1 and main collet body 2 is locked under the pressuring action of sliding sleeve 7.
Preferably, it is also possible to omit this rotary sleeve 8, as long as sliding sleeve 7 can rotate, it would however also be possible to employ other drive dress
Put, as oil cylinder, cylinder etc. drive rotary sleeve 8 or the rotation of sliding sleeve 7.
Main collet body, in the case of ensureing original main collet body precision and rigidity, is divided by the main folder head body device of the present invention
Solution becomes some, has both alleviated overall weight, easy to loading and unloading fast, only need to remove sliding sleeve 7, it is possible to the lightest
Take out remaining various piece, complete the dismantlement work of main folder head unit, reduce labor intensity and the difficulty of operator, improve
Work efficiency.
Although the preferred embodiments of the present invention described in detail above, it is to be clearly understood that for this area
For technical staff, the present invention can have various modifications and variations.All made within the spirit and principles in the present invention appoint
What amendment, equivalent, improvement etc., should be included within the scope of the present invention.
