Abstract
The utility model discloses a conduit drilling tool. The conduit drilling tool comprises a tool handle, a toolbar, a reamer and a drilling tool sequentially connected end to end, wherein the tool handle, the toolbar, the reamer and the drilling tool form an integrated structure; and the toolbar is an elongated toolbar. The conduit drilling tool not only can improve the product quality, but also can improve the production efficiency.
Description
Technical field
The utility model relates to field of machining, especially relates to a kind of conduit drilling tool.
Background technology
Existing a kind of length is 64 millimeters wear resistance castings conduit, because of instructions for use is had relatively high expectations to the linearity of its endoporus.Present general production method is by cutting with scissors two procedures after the subdrilling, at first adopt drill bit to hole on raw material, and then uses reamer to carry out reaming and repair the hole.Because boring is to be divided into two independent steps to carry out with repairing the hole in operating process, even same processing personnel also are difficult to guarantee the linearity of endoporus, so the product quality that processes is uneven, produces substandard products unavoidably.In addition,,, still adjust lathe, or adjust the processing personnel, all need spended time, have influence on working (machining) efficiency no matter be to the lathe tool changing owing to all will carry out the different operation in two roads at every turn.
The utility model content
At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of conduit drilling tool, and it has the crudy height, characteristics such as production efficiency height.
To achieve these goals, the technical scheme that the utility model adopted is: the conduit drilling tool is characterized in that it comprises end to end successively handle of a knife, knife bar, reamer and bore cutter, described handle of a knife, knife bar, reamer and bore cutter are structure as a whole, and described knife bar is the extended type knife bar.
Preferably, described reamer is that alloy material is made.
Preferably, described cutter axle center offers the oilhole that runs through whole cutter.
After adopting cutter of the present utility model, because drill bit and reamer are positioned on the same cutter, wear resistance castings conduit raw material is being added man-hour, it at first is the bore cutter contact raw material manufacturing procedure of holing, finish the boring back and continue to keep feed, the reamer follow-up touches the part of having holed on the raw material and carries out reaming and repair the hole process, can disposablely finish boring and repair the process in hole, the error of avoiding multi-pass operation to produce, the linearity that can guarantee the endoporus of wear resistance castings conduit reaches requirement, improved product processing quality, reduce substandard products and produce, also reduced by a procedure simultaneously, avoided operations such as tool changing and adjustment lathe, save a large amount of time, improved production efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of conduit drilling tool of the present utility model;
Fig. 2 is the cut-away view of conduit drilling tool of the present utility model.
Among the figure: 10, handle of a knife; 20, knife bar
30, reamer; 40, bore cutter;
50, oilhole.
The specific embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, see that Fig. 1 is to shown in Figure 2:
The utility model is a kind of conduit drilling tool, and it comprises end to end successively handle of a knife 10, knife bar 20, reamer 30 and bore cutter 40, and described handle of a knife 10, knife bar 20, reamer 30 and bore cutter 40 are structure as a whole, and described knife bar 20 is an extended type knife bar 20.Cutter of the present utility model, because drill bit and reamer 30 are positioned on the same cutter, wear resistance castings conduit raw material is being added man-hour, at first be the bore cutter 40 contact raw materials manufacturing procedures of holing, finish the boring back and continue to keep feed, reamer 30 follow-ups touch the part of having holed on the raw material and carry out reaming and repair the hole process, can disposablely finish boring and repair the process in hole, the error of avoiding multi-pass operation to produce, the linearity that can guarantee the endoporus of wear resistance castings conduit reaches requirement, improved product processing quality, reduce substandard products and produce, also reduced by a procedure simultaneously, avoided operations such as tool changing and adjustment lathe, save a large amount of time, improved production efficiency.
Since reaming with repair in the process of hole, reamer 30 is very easy to wearing and tearing, therefore described reamer 30 is made for alloy material, makes that the life-span of cutter is longer.Holing and repairing in the process of hole, cutter can cut a lot of iron filings from raw material inside, influence processing easily, therefore described cutter axle center offers the oilhole 50 that runs through whole cutter, can inject hydraulic oil in the oilhole 50 of handle of a knife 10 ends by pipeline man-hour adding, wash away iron filings from oilhole 50 ejections of bore cutter 40 after hydraulic oil enters in the oilhole 50 and clear up, avoided too much influencing processing because of iron filings.
Conduit drilling tool of the present utility model not only can improve the quality of products, and can also enhance productivity.
Claims (3)
