Abstract

The utility model relates to an eccentric milling cutter which comprises a knife handle and a cutting head, wherein the cutting head is fixed on the bottom surface of the knife handle through a cutter arbor, the cutter arbor is in a columnar structure, the center of the cutter arbor in the columnar structure deviates from the center of the knife handle, one side of the cutting head is welded with the cutter arbor, an upper blade is arranged at the top end of the cutting head, and a lower blade is arranged at the bottom end of the cutting head. The eccentric milling cutter has the beneficial effects that, the cutting head can be probed into a hole first, then, the knife handle is translated, the cutter arbor and the knife handle are probed into the hole, and the upper and lower surfaces in the hole can be milled through the upper and lower blades, so that the work efficiency is improved.

Description

Eccentric milling cutter

Technical field

The utility model relates to milling tool field, particularly a kind of milling cutter.

Background technology

In some industrial products, contain cavernous structure, for the part in hole, being difficult to milling cutter can enter, even have milling cutter can probe hole in, also have no idea the area beyond under circular hole to carry out milling processing, so these products adopt the mode of production of " connecing after first milling " more, reduce production efficiency.

Summary of the invention

The purpose of this utility model is in order to address the above problem, and has designed a kind of eccentric milling cutter.Specific design scheme is:

A kind of eccentric milling cutter, comprise handle of a knife, cutter head, described cutter head is fixed on the bottom surface of described handle of a knife by knife bar, described knife bar is column structure, and the misalignment of described knife bar column structure is in the center of described handle of a knife, one side of described cutter head and the welding of described knife bar, the top of described cutter head is provided with cutter, and the bottom of described cutter head is provided with bottom knife.

Described handle of a knife is cylindrical structure.

Described cutter, bottom knife all deviate from the cross section of described handle of a knife bottom surface.

The eccentric milling cutter obtaining by technique scheme of the present utility model, its beneficial effect is:

Described eccentric milling cutter can be first by described cutter head probe hole, translation handle of a knife then, then by knife bar and handle of a knife probe hole, and by cutter and bottom knife, the upper and lower surface in hole is carried out to milling processing, increase work efficiency.

Accompanying drawing explanation

Fig. 1 is the structural representation of eccentric milling cutter described in the utility model;

Fig. 2 is the structural representation of looking up of eccentric milling cutter described in the utility model;

In figure, 1, handle of a knife; 2, cutter head; 3, knife bar; 4, cutter; 5, bottom knife.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is specifically described.

Fig. 1 is the structural representation of eccentric milling cutter described in the utility model; Fig. 2 is the structural representation of looking up of eccentric milling cutter described in the utility model, as shown in Figure 1 and Figure 2, a kind of eccentric milling cutter, comprise handle of a knife 1, cutter head 2, described cutter head 2 is fixed on the bottom surface of described handle of a knife 1 by knife bar 3, and described knife bar 3 is column structure, and the misalignment of described knife bar 3 column structures is in the center of described handle of a knife 1, one side of described

cutter head

2 and 3 welding of described knife bar, the top of described cutter head 2 is provided with cutter 4, and the bottom of described cutter head 2 is provided with bottom knife 5.

Described handle of a knife 1 is cylindrical structure.

Described cutter 4, bottom knife 5 all deviate from the cross section of described handle of a knife 1 bottom surface.

During use, first the center of described cutter head 2 is aimed to the center of circular hole, after cutter head 2 is probeed in circular hole, again described handle of a knife 1 is carried out to translation, make the center of the center aligning circular hole of described handle of a knife 1, and then described handle of a knife 1 is probeed into circular hole, and and carrying out milling by the upper surface in space in 5 pairs of circular holes of bottom knife, the lower surface by space in 4 pairs of circular holes of described cutter carries out milling.

Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art have all embodied principle of the present utility model to some changes that wherein some part may be made, within belonging to protection domain of the present utility model.
