Abstract

The utility model discloses an anti - finish boring sword of eccentric formula in big drop aperture for work piece machine tooling, this boring cutter be including side stationary handle of a knife, anti - boring cutter pole, finish boring head and mount pad, anti - boring cutter peak of the staff end is eccentric to be connected side stationary handle of a knife, the mount pad is located anti - boring cutter pole bottom, an installing hole is arranged in the installing base, the finish boring head is located and through the peripheral fix with screw of finish boring head in the mounting hole. This boring cutter utilizes eccentric formula structure to increase cutter arbor diameter and width, effectively improves the mechanical rigidity of cutter arbor, and the vibrations avoiding the work in -process and arouse because the cutter rigidity is not enough have improved the machining precision and the efficiency of work piece.

Description

For the anti-fine boring cutter of the mach large drop aperture centering type of workpiece
Technical field
The utility model relates to a kind of for the anti-fine boring cutter of the mach large drop aperture centering type of workpiece.
Background technology
Boring cutter is the one of cutting tool for boring, is generally circle handle, also has larger workpiece user knife bar, and the most frequently used occasion is exactly inner hole of workpiece processing, and reaming, profiling etc., are specifically designed to and carry out roughing, semifinishing or accurately machined cutter to existing hole.Boring cutter can use on boring machine, lathe or milling machine.But when the anti-bore hole of work pieces process, when processing anti-bore hole footpath and via hole aperture differs greatly, traditional boring cutter diameter is owing to being subject to the restriction in via hole aperture, process very easily produces cutter phenomenon of shaking., affect the processing in workpiece aperture, reduce the machining accuracy of workpiece, even cause scrapping of workpiece.Some workpiece is owing to being subject to the restriction in knife bar diameter and anti-bore hole footpath and via hole aperture simultaneously, is difficult to commercially find suitable cutter, causes great difficulty, improve the processing cost of workpiece to processing.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of for the anti-fine boring cutter of the mach large drop aperture centering type of workpiece, this boring cutter utilizes eccentric type structure to increase knife bar diameter and width, the mechanical rigid of effective raising knife bar, the vibrations avoiding work in-process to cause because cutter rigidity is not enough, improve machining accuracy and the efficiency of workpiece.
For solving the problems of the technologies described above, the utility model is used for the anti-fine boring cutter of the mach large drop aperture centering type of workpiece and comprises side-strengthened handle of a knife, reverse boring cutter bar, fine boring head and mount pad, described reverse boring cutter masthead end bias connects described side-strengthened handle of a knife, described mount pad is located at described reverse boring cutter bar bottom, described mount pad is provided with installing hole, and described fine boring head is positioned at described installing hole and is fixed by the screw of fine boring head periphery.
Further, described reverse boring cutter masthead end radial direction is provided with clinoplain and bias is inserted in described side-strengthened handle of a knife, and described reverse boring cutter bar and side-strengthened handle of a knife are fixed by fastening bolt.
Technique scheme is have employed because the utility model is used for the anti-fine boring cutter of the mach large drop aperture centering type of workpiece, namely this boring cutter comprises side-strengthened handle of a knife, reverse boring cutter bar, fine boring head and mount pad, described reverse boring cutter masthead end bias connects described side-strengthened handle of a knife, described mount pad is located at described reverse boring cutter bar bottom, described mount pad is provided with installing hole, and described fine boring head is positioned at described installing hole and is fixed by the screw of fine boring head periphery.This boring cutter utilizes eccentric type structure to increase knife bar diameter and width, effectively improves the mechanical rigid of knife bar, and the vibrations avoiding work in-process to cause because cutter rigidity is not enough, improve machining accuracy and the efficiency of workpiece.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is that the utility model is for the anti-fine boring cutter structural representation of workpiece mach large drop aperture centering type.
Detailed description of the invention
Embodiment as shown in Figure 1, the utility model is used for the anti-fine boring cutter of the mach large drop aperture centering type of workpiece and comprises side-strengthened handle of a knife 1, reverse boring cutter bar 2, fine boring head 3 and mount pad 4, described reverse boring cutter bar 2 top bias connects described side-strengthened handle of a knife 1, described mount pad 4 is located at described reverse boring cutter bar 2 bottom, described mount pad 4 is provided with installing hole 41, and described fine boring head 3 is positioned at described installing hole 41 and is fixed by the screw 5 of fine boring head 3 periphery.
Preferably, described reverse boring cutter bar 2 top radial direction is provided with clinoplain 21 and bias is inserted in described side-strengthened handle of a knife 1, and described reverse boring cutter bar 2 is fixed by fastening bolt 6 with side-strengthened handle of a knife 1.
In workpiece machined, classical inverse fine boring cutter is limited by the impact needing aperture difference between anti-bore hole and anti-boring via hole, between the maximum 20mm of both hole differences, and this large anti-fine boring cutter of drop aperture centering type, both holes are poor maximum reaches 60mm, embodies " large drop " design.
When workpiece machining operation, can the size in root root work pieces process aperture and the degree of depth in hole, according to the corresponding change design size of the principle of this boring cutter, by redesigning the length of the eccentric distance of side-strengthened handle of a knife and reverse boring cutter bar, diameter and reverse boring cutter bar, the diameter, the minimum tool length that increase cutter according to workpiece of maximum likelihood, avoid the generation of shake cutter phenomenon, thus ensure that the machining accuracy of workpiece, improve machined efficiency and stability; This boring cutter structure is simple simultaneously, and easy to make, cost is low, and has good practicality.
