Abstract
The utility model relates to a novel boring tool, which comprises a taper shank and a positioning clamp groove. The taper shank is inserted into a machine tool, a boring bar of a finish boring tool is disposed below the taper shank, the finish boring tool is mounted on the boring bar of the finish boring tool, a boring bar of a heavy boring tool is arranged below the boring bar of the finish boring tool, the diameter of the boring bar of the heavy boring tool is smaller than that of the boring bar of the finish boring tool, the heavy boring tool is mounted on the boring bar of the heavy boring tool, and both the finish boring tool and the heavy boring tool are movably connected onto the boring bar of the finish boring tool and the boring bar of the heavy boring tool respectively. When the novel boring tool is used for machining a hole with a large aperture, the heavy boring tool mounted on the smaller-diameter boring bar of the heavy boring tool is firstly used for heavy boring, then the finish boring tool mounted on the larger-diameter boring bar of the finish boring tool realizes finish boring, accordingly, the surface roughness of a machined hole meets requirements, abrasion of the boring tools is reduced, and the service life of the novel boring tool is prolonged.
Description
Technical field
The utility model relates to a kind of cutter, refers in particular to a kind of novel boring cutter that is used for hole processing, belongs to the metal cutting processing technique field.
Background technology
In machining, during the hole that multiple aperture is bigger processes,, cause processing capacity excessive if adopt a boring cutter directly to process, the wearing and tearing of boring cutter are bigger, influence the service life of boring cutter.
And the vibratory output that boring bar produces in process is big, and the surface in the hole that processes is prone to ripple, influences the crudy in hole, can't reach the requirement of product surface roughness.
The utility model content
The utility model purpose is to provide a kind of when bigger hole, processing aperture for the deficiency that overcomes prior art, the high and novel boring cutter that can prolong cutter life of machining accuracy.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of novel boring cutter comprises the taper shank and the locating groove that insert lathe; The below of said taper shank is provided with the fine boring cutter boring bar; On the said fine boring cutter boring bar fine boring cutter is installed; Said fine boring cutter boring bar below is provided with the diameter heavy boring cutter boring bar littler than fine boring cutter boring bar; On the said heavy boring cutter boring bar heavy boring cutter is installed.
Preferably, said fine boring cutter and heavy boring cutter all are installed in respectively on fine boring cutter boring bar and the heavy boring cutter boring bar through flexibly connecting.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The novel boring cutter of the utility model; In the wide-aperture hole of processing; At first adopt the heavy boring cutter that is installed on the less heavy boring cutter boring bar of diameter to carry out heavy boring, carrying out right boring through the fine boring cutter that is installed on the bigger fine boring cutter boring bar of diameter then, the surface roughness in the feasible hole that processes reaches requirement; And the less wear extent of boring cutter has prolonged service life.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the stereogram of the novel boring cutter of the utility model;
Accompanying drawing 2 is the cutaway view of the novel boring cutter of the utility model;
Wherein: 1, taper shank; 2, locating groove; 3, fine boring cutter boring bar; 4, fine boring cutter; 5, heavy boring cutter boring bar; 6, heavy boring cutter.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Like accompanying drawing 1, the described a kind of novel boring cutter of the utility model shown in 2, comprise the taper shank 1 and locating groove 2 that insert lathe; The below of said taper shank 1 is provided with fine boring cutter boring bar 3; On the said fine boring cutter boring bar 3 fine boring cutter 4 is installed; Said fine boring cutter boring bar 3 belows are provided with the diameter heavy boring cutter boring bar 5 littler than fine boring cutter boring bar 3; On the said heavy boring cutter boring bar 5 heavy boring cutter 6 is installed; Said fine boring cutter 4 all is installed in respectively on fine boring cutter boring bar 3 and the heavy boring cutter boring bar 5 through flexibly connecting with heavy boring cutter 6.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The novel boring cutter of the utility model; In the wide-aperture hole of processing; At first adopt the heavy boring cutter that is installed on the less heavy boring cutter boring bar of diameter to carry out heavy boring, carrying out right boring through the fine boring cutter that is installed on the bigger fine boring cutter boring bar of diameter then, the surface roughness in the feasible hole that processes reaches requirement; And the less wear extent of boring cutter has prolonged service life.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
