Abstract
The utility model provides a step drilling cutter which comprises a drill installing base, a one-level cutter base and a two-level cutter base all of which are arranged in a step mode. A drill is installed on the drill installing base, the one-level cutter base and the two-level cutter base are provided with installing grooves axially distributed, and tool bits are installed on the installing grooves. The lower portion of the two-level cutter base is connected with an installing shaft. The step drilling cutter can directly drill to form a plurality of holes with different sizes under the condition that the cutter is not replaced and can also drill to form stepped holes at a time, wherein the formed stepped holes are more accurate in positioning.
Description
Technical field
The utility model relates to the cutting-tool engineering field, is specifically related to a kind of step drill spot facing cutter.
Background technology
All designed pore structure on many parts, be used for assembling or fastenings; Hole processing generally is divided into boring, fraising, reaming, several modes of bore hole; People use drilling machine and boring machine to come machining hole usually, and when holing with drilling machine, though speed is very fast, the inner surface in hole is very coarse, and each drill bit when the hole of other size of processing, needs more bit change only to process the hole of a size.And when using the boring machine machining hole, though machining accuracy is higher, the processing dimension in hole also can be regulated, and the boring cutter on the boring machine has only a cutting point, and the rotating speed of boring cutter is also slower, and described bore hole speed is slower.And usually need be to the Working position prebored hole before bore hole, process is more loaded down with trivial details, and working (machining) efficiency is lower.
Summary of the invention
At above problem, the utility model provides a kind of use on lathe, can a plurality of holes of disposable processing under without the situation of tool changing, and process velocity step drill spot facing cutter faster.
The technical scheme that its technical problem that solves the utility model adopts is: this step drill spot facing cutter comprises drill bit mount pad, the one-level base of tool, the secondary base of tool that ladder is arranged; On the described drill bit mount pad drill bit is installed, all designing on the described one-level base of tool, the secondary base of tool has uniform vertically mounting groove, on the described mounting groove cutter head is installed; Described secondary base of tool bottom is connected with installation shaft.
As preferably, described cutter head is fan-shaped, and described mounting groove is the right angle grooving; Four mounting grooves are respectively arranged on the described one-level base of tool, the secondary base of tool.
As preferably, described cutter head uses screw to be fastened on the mounting groove.
The beneficial effects of the utility model are: the cutter head that has drill bit and cutting usefulness on this step drill spot facing cutter, its surfaces of revolution is stairstepping, can be under the situation of not changing cutter, directly process the different hole of a plurality of sizes, and being separately installed with a plurality of cutter heads on the described one-level base of tool, the secondary base of tool, cutting speed is faster; This step drill spot facing cutter can also the disposable shoulder hole that processes, and the shoulder hole that processes location is more accurate.
Description of drawings
Fig. 1 is the perspective view of this step drill spot facing cutter.
Fig. 2 is that A among this step drill spot facing cutter Fig. 1 is to schematic diagram.
The specific embodiment
Further specify below in conjunction with the utility model of embodiment:
Shown in embodiment among Fig. 1 and Fig. 2, this step drill spot facing cutter comprises drill bit mount pad 1, the one-level base of tool 2, the secondary base of tool 3 that ladder is arranged; On the described drill bit mount pad 1 drill bit 4 is installed, all designing on the described one-level base of tool 2, the secondary base of tool 3 has uniform vertically mounting groove 5, on the described mounting groove 5 cutter head 6 is installed; The described secondary base of tool 3 bottoms are connected with installation shaft 7.Described installation shaft 7 is used for the cutter of lathe head assembling mutually being installed.
This step drill spot facing cutter mainly uses at drilling machine, on milling machine or the boring machine, be used for being the part processing hole, the cutter head 6 that has drill bit 4 and cutting usefulness on this utility model simultaneously, its surfaces of revolution is stairstepping, according to drill bit 4 diameters, and the one-level base of tool 2, the outer most edge diameter of described cutter head 6 surfacess of revolution is installed on the secondary base of tool 3, can be under the situation of not changing cutter, directly process the different hole of a plurality of sizes at part, and the described one-level base of tool 2, be separately installed with a plurality of cutter heads 6 on the secondary base of tool 3, with to use boring cutter to compare its cutting speed faster; This step drill spot facing cutter can also the disposable shoulder hole that processes, and the location of described shoulder hole determines by the assembling between drill bit mount pad 1, the one-level base of tool 2, the secondary base of tool 3 threes, and is more accurate.
As depicted in figs. 1 and 2, described cutter head 6 is fan-shaped, and described mounting groove 5 is the right angle grooving; Four mounting grooves 5 are respectively arranged on the described one-level base of tool 2, the secondary base of tool 3.During cutter head 6 machining holes on using the one-level base of tool 2, the secondary base of tool 3, have four cutter heads 6 cutting simultaneously like this, speed is faster.
As depicted in figs. 1 and 2, described cutter head 6 uses screw 8 to be fastened on the mounting groove 5.Use the screw location very convenient.
