Therefore, the combined knife sleeve capable of automatically matching is provided.
The utility model aims at realizing through the following technical scheme:
the utility model discloses an automatic matching combined knife pouch, which comprises a knife pouch body, a plurality of movable sleeves and a reset spring, wherein the front end of the knife pouch body is provided with a large-size inner hole, the movable sleeves are spliced layer by layer and axially limited in the large-size inner hole of the knife pouch body, and the reset spring is respectively arranged at the rear end of each movable sleeve; each movable sleeve is an annular sleeve with different inner diameters, the outer diameter of each movable sleeve is matched with the inner diameter of the outer movable sleeve, and the outer diameter of the outermost movable sleeve is matched with the inner diameter of the large-size inner hole of the cutter sleeve body; the side wall of each movable sleeve is radially provided with a screw through hole, and the side wall of the front end of the knife sleeve body is radially provided with a screw connecting hole; when all the movable sleeves are in a forward axial limiting state, the screw through holes in the side wall of each movable sleeve are aligned with the screw connecting holes in the side wall of the front end of the cutter sleeve body;
the front end of the combined cutter sleeve is pushed into the rear end of the cutter bar to be assembled, the movable sleeve with the diameter smaller than that of the cutter bar to be assembled backwards compresses the return spring corresponding to the movable sleeve, and the screw through hole of the outer cutter sleeve is left, so that the movable sleeve with the matched inner diameter is sleeved at the rear end of the cutter bar to be assembled; and a locking screw penetrates through a screw connecting hole in the side wall of the front end of the cutter sleeve body and screw through holes in the side walls of all the movable sleeves which are not compressed backwards, so that the cutter bar to be assembled is pressed and fixed.
The rear end of the sliding hole of the knife pouch body is encapsulated by a plug cover fixed by threads; the inboard face of blanking cover is equipped with spring mount pad, sets up the reset spring of each movable sleeve rear end passes through spring mount pad is connected the inboard face of blanking cover.
And connecting key structures are processed between the outer wall of each movable sleeve and the inner wall of the outer movable sleeve and between the outermost movable sleeve and the inner wall of the front end of the cutter sleeve body, so that the screw through holes in the side wall of each movable sleeve are circumferentially positioned with the screw connecting holes in the front end of the cutter sleeve body.
The front end surfaces of the movable sleeves are inclined planes which incline inwards, so that the rear ends of the cutter bars to be assembled slide towards the centers of the movable sleeves through the inclined planes.
Advantageous effects
The utility model discloses a combination knife pouch, simple structure, convenient to use can match the assembly of different diameter cutter arbor automatically, not only saves assembly cost, has improved assembly efficiency simultaneously, is applicable to big batch processing and uses.

Detailed Description
The contents of the present invention will be further explained with reference to the drawings and examples.
Examples
As shown in fig. 1 and 2, an automatic matching combined tool holder comprises a tool holder body 1 with a large-size inner hole at the front end, two movable sleeves inserted layer by layer and axially limited in the large-size inner hole of the tool holder body 1, and return springs 6 respectively arranged at the rear ends of the two movable sleeves; the two movable sleeves are annular sleeves with different inner diameters, the outer diameter of the inner movable sleeve 3 is matched with the inner diameter of the outer movable sleeve 2, and the outer diameter of the outer movable sleeve 2 is matched with the inner diameter of a large-size inner hole of the knife sleeve body 1; the side walls of the two movable sleeves are radially provided with screw through holes, and the side wall of the front end of the knife sleeve body 1 is radially provided with screw connecting holes; when the two movable sleeves are in a forward axial limiting state, the screw through holes in the side walls of the two movable sleeves are aligned with the screw connecting holes in the side wall of the front end of the knife sleeve body 1;
