Abstract

A back-milling chamfer forming milling cutter comprises a cutter handle and a mounting seat, wherein the rear end of the cutter handle is connected with the mounting seat; the front end of the cutter handle is connected with a cutter bit; the cutter bit is shaped like an inverted triangle; the front end of the cutter handle is the vertex angle of the inverted triangle; the inverted triangle is divided into a left cutter bit and a right cutter bit which are in central symmetry about the center line of the cutter handle; each of the top surface of the left cutter bit and the bottom surface of the right cutter bit is provided with a blade slot; and a hard alloy sheet is arranged on each blade slot. The back-milling chamfer forming milling cutter provided by the utility model is capable of effectively machining the chamfer of the inner side of a key slot.

Description

The anti-chamfering profile milling cutter that mills

Technical field

The utility model relates to a kind of profile milling cutter.

Background technology

When the inboard chamfering of processing one place's keyway, because this chamfering space, inboard is less, can not carry out front processing, there is interference problem in processing.

Summary of the invention

In order to overcome existing profile milling cutter since the space less can't process the inboard chamfering of keyway deficiency, the utility model provides the anti-chamfering profile milling cutter that mills of the inboard chamfering of a kind of effective processing keyway.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of anti-chamfering profile milling cutter that mills, comprise handle of a knife and mount pad, the rear end of described handle of a knife is connected with mount pad, described handle of a knife front end is connected with cutter head, described cutter head is del, and described handle of a knife front end is the drift angle of described del, and described del is arranged symmetrically with centered by described handle of a knife center line and is divided into left cutter head and right cutter head, the end face of described left cutter head and the bottom surface of right cutter head are provided with insert groove, on the described insert groove hard metal tip are installed.

The beneficial effects of the utility model are mainly manifested in: effectively process the inboard chamfering of keyway.

Description of drawings

Fig. 1 is the anti-schematic diagram that mills the chamfering profile milling cutter.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the anti-stereogram that mills the chamfering profile milling cutter.

The specific embodiment

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

With reference to Fig. 1～Fig. 3, a kind of anti-chamfering profile milling cutter that mills, comprise handle of a knife 1 and mount pad 2, the rear end of described handle of a knife 1 is connected with mount pad 2, and described handle of a knife 1 front end is connected with cutter head 3, and described cutter head 3 is del, described handle of a knife front end is the drift angle of described del, described del is arranged symmetrically with centered by described handle of a knife center line and is divided into left cutter head and right cutter head, and the end face of described left cutter head and the bottom surface of right cutter head are provided with insert groove, and hard metal tip 4 is installed on the described insert groove.

The tool bit part dimension width of the present embodiment can not surpass keyway gap size to be processed,, length direction can not be greater than keyway length.The cutter neck can not be greater than width of keyway.Cutter is cut flat prescription to considering side compact form handle of a knife clamping direction and machining center main shaft orienting station.

Process is: cutter X-axis, Y-axis navigate to the keyway center, and main shaft directed (the cutter length and width are consistent with the keyway length and width) enters keyway inside.Arrive emplacement depth → main shaft forward → feed speed rollback be worked into chamfering width dimensions → X axis back and forth feeding be worked into keyway length dimension → Z axis withdrawing to the safe place (because be counter milling, depth direction advances 1mm) → get back to keyway center → main shaft orientation → cutter to return security plane → process finishing.

The milling cutter of the present embodiment is counter to be milled around contour machining, both saves process time, can reach technological requirement again.

Claims

1. anti-chamfering profile milling cutter that mills, comprise handle of a knife and mount pad, the rear end of described handle of a knife is connected with mount pad, it is characterized in that: described handle of a knife front end is connected with cutter head, described cutter head is del, and described handle of a knife front end is the drift angle of described del, and described del is arranged symmetrically with centered by described handle of a knife center line and is divided into left cutter head and right cutter head, the end face of described left cutter head and the bottom surface of right cutter head are provided with insert groove, on the described insert groove hard metal tip are installed.
