Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

In figure：1st, handle of a knife；2nd, knife bar；3rd, cutter head；4th, cutter head relief angle；5th, cutter head cutting edge inclination；6th, fixed pan.

Embodiment

The utility model is explained in detail below in conjunction with the accompanying drawings.

A kind of eccentric nonstandard boring cutter as shown in Figure 1, including facilitate handle of a knife 1 that machine clamped, conveniently stretch into workpiece Knife bar 2 and the cutter head 3 that is processed to workpiece, described handle of a knife 1 be located at the one end of knife bar 2, described cutter head 3 is located at knife bar 2 other end, described cutter head 3 are located at the side of the end of knife bar 2, and the end of knife bar 2 at the described rear portion of cutter head 3 is cutter head relief angle 4, cutter head 3 is located at the side of knife bar 2, realizes the processing to endoporus side, described conveniently in internal orifice dimension to the processing on direction Cutter head relief angle 4 is 3 °~10 °, in order to ensure not interfering with the bottom surface of endoporus during processing, after further preferred cutter head The angle at angle 4 is 5 °, described cutter head 3 in 1/4 it is spherical be fixed on knife bar 2, ensure that the upper fillet of dowel, lower fillet with And the disposable machine-shaping of semi arch, described cutter head cutting edge inclination 5 improve the rigidity of cutter by arc transition, and upwards Smooth chip removal.

Further, described handle of a knife 1 is not conllinear with the axis of knife bar 2, is rotated after machine clamps handle of a knife 1 so that knife Bar 2 surrounds the center rotating of handle of a knife 1, the increase of the rotation amplitude of cutter head 3, and when use, machine first passes through endoporus and positioned, by knife Bar 2 is put into endoporus, is moved handle of a knife 1 afterwards and is caused cutter head 3 to be located at required position, and the handle of a knife 1 of machine driving afterwards is rotated, Cutter head 3 is processed to dowel, and machine drives handle of a knife 1 to move up and down and completes the processing of whole piece dowel, meanwhile, when cutter head 3 During positioned at dowel least significant end, the bottom circular arc of cutter head 3 completes the processing to lower fillet, when cutter head 3 is located at dowel top, The circular arc on the top of cutter head 3 completes the processing to upper fillet.Knife bar 2 be located at handle of a knife 1 position can be designed as it is adjustable, according to Its size for needing to process endoporus is adjusted, and the regulation of position can use manual mode or automatic mode to adjust, position The regulation put can increase or reduce the size that the diameter that cutter head 3 rotates adapts to the diameter of endoporus with this, improve cutter The scope of application.

Further, clamping unit is set on the cylinder of handle of a knife 1, for clamping handle of a knife 1, its frame mode is in handle of a knife 1 The fixed pan 6 of milling one on cylinder, and clamped by the fixture relative with the fixed pan 6；The form of clamping unit has more Kind various, such as the form such as keyway, swelling and buckle, its main function has two, and first, prevent cutter from turning relative to fixture It is dynamic, second, for cutter to be fixed on into fixture.

According to real work needs, the radius of cutter head 3 is defined as 1.5mm, the convenient top to dowel and bottom fillet Processing.

In manufacturing process, handle of a knife 1, knife bar 2 and cutter head 3 are integral, are process using hard alloy, and hard closes Gold is wolfram steel, and hard alloy has high hardness, wear-resisting, intensity and a series of premium properties such as toughness is preferable, heat-resisting, corrosion-resistant, The particularly protrusion of its high rigidity and wearability, therefore relatively it is used for cutter.It is better using the cutter of hard alloy, its rigidity Good, machining accuracy is higher.

To sum up, the special tool of design is used to add aviation assisted engine gas distribution part dowel semi arch Work, the semi arch of dowel is processed by the middle part of cutter head 2, the upper fillet of dowel is processed by the top of cutter head 2, passes through cutter head 2 Bottom processes the lower fillet of dowel, and whole process can be saved big with one-shot forming semi arch, upper fillet and lower fillet Measure time and cost.

It is emphasized that：It the above is only preferred embodiment of the present utility model, not the utility model appointed What formal limitation, every any simple modification made according to the technical essence of the utility model to above example, etc. With change and modification, in the range of still falling within technical solutions of the utility model.
