Abstract
The utility model discloses a composite deep hole guide boring cutter, which belongs to the technical field of a metal cutting tool and aims to solve the technical problems of high probability of vibration of a cutter body, poor stability and difficulty in guaranteeing of machining accuracy in case of long suspension of a cutter handle lengthening cutter in a deep hole machining process. The composite deep hole guide boring cutter is characterized in that a guide device is also arranged between the cutter body and the lengthening cutter handle, wherein the guide device has two forms, i.e., a guide ring form and a guide strip form; and the external diameter of the guide device is in movable fit with the aperture of a deep hole to be machined. Compared with the prior art, the guide device is arranged between the cutter body and the lengthening cutter handle, a middle supporting effect can be effectively achieved while deep hole machining is performed by the cutter, so that the suspension of the cutter is shortened, thereby reducing the vibration, enhancing the stability, meeting rough and fine boring machining requirements of deep holes within 10 times the diameter after connection of the cutter body and the lengthening cutter handle and guaranteeing the machining accuracy.
Description
Technical field
The utility model belongs to the metal-cutting machine tool technical field, relates to the deep hole machining boring cutter, is specifically related to a kind of rimmer knife handle combined type guiding boring cutter for deep hole machining.
Background technology
Boring cutter is a kind of of cutting tool for boring, and boring cutter can use at boring machine, lathe or milling machine, is used for roughing, semifinishing or fine finishining are carried out in existing hole.In the deep hole machining occasion, just simply with the handle of a knife lengthening of common boring cutter, form handle of a knife and lengthen boring cutter usually.But handle of a knife is connected simply with cutter hub, not only structure is single, be difficult for adjusting, and handle of a knife lengthening tool diameter is thin in the deep hole machining process, the aperture of deep hole is thick, and handle of a knife lengthens cutter and overhangs and longly occur the cutter hub vibration easily, thereby processing back deep hole size can not be guaranteed well, poor stability is difficult to satisfy the deep hole machining needs.
Summary of the invention
The purpose of this utility model is: provide a kind of not only being easy to adjust, and the combined type deep hole guiding boring cutter that is applicable to deep hole machining of good stability.
For achieving the above object, the technical scheme that adopts is: a kind of combined type deep hole guiding boring cutter, comprise the tool rest that lengthens handle of a knife, cutter hub and be connected and fixed with described cutter hub, be connected and fixed by short tapered joint mouth between described cutter hub and the described lengthening handle of a knife, its characteristics are: also be equipped with guider between described cutter hub and the described lengthening handle of a knife, described guider places the outside of described cutter hub, and the aperture of its external diameter and deep hole to be processed movingly.
Described guider is guide ring, and the internal diameter of described guide ring and described cutter hub external diameter are movingly.
Described guider is gib block, and described gib block quantity has a plurality of, and is axially uniform, is threaded fixing with described cutter hub.
Compared with prior art, the guider that is equipped with between the utility model cutter hub and the lengthening handle of a knife, when cutter carries out deep hole machining, can play the intermediate supports effect effectively, cutter is shortened overhang, thereby reduce vibrations, strengthen stability, can satisfy 10 times of footpaths with thick, the right boring processing request of interior deep hole after making described cutter hub and the lengthening handle of a knife being connected, guarantee machining accuracy.
Description of drawings
The utility model is described in further detail in explanation below by way of embodiments and drawings.
Fig. 1 is the structural representation of combined type deep hole guiding boring cutter;
Fig. 2 is that cutter hub is connected joint portion short tapered joint mouth sectional structure schematic diagram among Fig. 1 with the lengthening handle of a knife;
Fig. 3 is the A-A sectional structure schematic diagram (guide ring) of Fig. 1;
Fig. 4 is the A-A sectional structure schematic diagram (gib block, quantity are 3) of Fig. 1.
Among the figure, the 1-cutter hub; 2-lengthens handle of a knife; The 3-tool rest; The short tapered joint mouth of 4-; The 5-guider; The 6-guide ring; The 7-gib block.
The specific embodiment
Fig. 1 is the structural representation of combined type deep hole guiding boring cutter, and Fig. 2 is that cutter hub is connected joint portion short tapered joint mouth sectional structure schematic diagram among Fig. 1 with the lengthening handle of a knife, and Fig. 3 and Fig. 4 are respectively the sectional structure schematic diagrames of Fig. 1 guide ring and gib block.As seen from the figure: a kind of combined type deep hole guiding boring cutter, comprise the tool rest 3 that lengthens handle of a knife 2, cutter hub 1 and be connected and fixed with described cutter hub 1, be connected and fixed by short tapered joint mouth 4 between described cutter hub 1 and the described lengthening handle of a knife 2, its characteristics are: also be equipped with guider 5 between described cutter hub 1 and the described lengthening handle of a knife 2, described guider 5 places the outside of described cutter hub 1, and the external diameter of described guider 5 and the aperture of deep hole to be processed are movingly.
Described guider 5 is guide ring 6, and the internal diameter of described guide ring 6 and described cutter hub 1 external diameter are movingly.
Described guider 5 is gib block 7, and described gib block 7 quantity have a plurality of (gib block quantity is 3 among Fig. 4), and are axially uniform, are threaded fixing with described cutter hub 1.
During use, cutter hub 1 with lengthen handle of a knife 2 link installation and guide devices 5, and with lengthen handle of a knife 2 and lack tapered joint mouth 4 and be connected and fixed, finish grinded on guider 5 surfaces, and between the hole to be processed movingly, stay the gap slightly.When adjustable insert seat 3 was transferred to the dimensional requirement processing parts, cutter was deep into part to be processed inside, and guider 5 plays the intermediate supports effect therebetween, overhang thereby shorten cutter, made cutter minimizing vibration in the process, strengthened the cutter processing stability.During general heavy boring, guider 5 is selected for use and is guide ring 6, the external diameter of guide ring 6 and the aperture of deep hole to be processed, and the internal diameter of guide ring 6 and described cutter hub 1 external diameter are movingly, therefore guide ring 6 is when deep hole processing is rotated, can slide clockwise or counterclockwise, not only can not be stuck, and can play the intermediate supports effect well.The thin general Bian gib block 7 in during right boring because aperture, gib block 7 contacts with inner walls of deep holes single-point line, playing the intermediate supports effect simultaneously, also is not easy to be stuck, and can effectively protect the operation of boring cutter normal process.
