Abstract

The utility model relates to a tool for cutting metals, in particular relates to a drilling and milling compound T type tool. Convex parts protruding outwards towards the diameter are arranged on a tool bit of the tool and is outwards provided with a cutting blade A5, the tool bit at two sides of the convex parts is respectively outwards provided with a cutting blade A4 and a cutting blade A6, connecting parts of the convex parts and the tool bit are respectively provided with a forward cutting blade A2 and a backward cutting blade A3, the front end of the tool bit is provided with a cutting blade A1, the cutting blades A1 and A2 have the function of a drilling and milling blade and also have the function of a end surface milling blade, the cutting blade A3 is the end surface milling blade, and the cutting blades A4, A5 and A6 are milling blades. According to the drilling and milling compound T type tool disclosed by the utility model, the technical problems of long machining time and low efficiency because a groove in a hole is machined by using a straight-flute tool and the T-type tool in the prior art are mainly used, the two original tools are changed into one tool, and thus the machining efficiency is increased by one time, and the manufacture cost is greatly reduced.

Description

A kind of brill mills compound T type cutter

Technical field

The utility model relates to the stage property of cutting metal, and particularly a kind of brill mills compound T type cutter.

Background technology

In some aluminum alloy part, in the hole, design a groove (like Fig. 1) through regular meeting; And the technology of the existing processing of this type groove mainly is; Process identical straight trough cutter with the aperture (like Fig. 2,3) to the hole with one earlier, use a T type cutter (like Fig. 4,5) to come working groove through walking the circular interpolation milling again through the numerical control machining center machine.

Above-mentioned defective workmanship is when the hole of manuscript 1, to have two cutters to process, and long processing time can influence to produce and render a service like this, increases production cost.

The utility model content

The purpose of the utility model is to provide a kind of brill to mill compound T type cutter; Mainly solve prior art machining hole inside groove and need use straight trough cutter and T type cutter; Long processing time, inefficient technical problem; It becomes two original cutters into one, and working (machining) efficiency doubles, and reduces manufacturing cost greatly.

For realizing above-mentioned purpose, the utility model is to realize like this.

A kind of brill mills compound T type cutter; It is characterized in that: the protuberance that is provided with protrusion beyond diameter at cutter cutter head place; This protuberance outwards has cutting edge A5; Outwards have cutting edge A4, A6 on the cutter head of protuberance both sides respectively, described protuberance and cutter head connecting portion also have respectively forward and backward cutting edge A2 and A3, and the cutter head front end also has cutting edge A1; Wherein, described cutting edge A1, A2 are that the drilling sword also has face milling sword function simultaneously, and cutting edge A3 is the face milling sword, and described cutting edge A4, A5, A6 are milling edges.

Described brill mills compound T type cutter, it is characterized in that: the diameter at described cutter cutter head place is φ d, and the diameter of protuberance is φ d1, and part to be processed aperture is φ D, and the groove in the hole directly is φ D1; φ d1-φ d=φ D1-φ D.

The utility model is compared with existing mechanism, has following advantage.

The brill of the utility model mills compound T type cutter, when on Digit Control Machine Tool, using, owing to be to bore to mill compound T type cutter, two original cutters is become one, and working (machining) efficiency doubles, and reduces manufacturing cost greatly.

The specific embodiment

See also Fig. 6-7, the utility model discloses a kind of brill and mill compound T type cutter.As shown in the figure: the protuberance that is provided with protrusion beyond diameter at cutter cutter head place; This protuberance outwards has cutting edge A5; Outwards have cutting edge A4, A6 on the cutter head of protuberance both sides respectively; Described protuberance and cutter head connecting portion also have respectively forward and backward cutting edge A2 and A3, and the cutter head front end also has cutting edge A1; Wherein, described cutting edge A1, A2 are that the drilling sword also has face milling sword function simultaneously, and cutting edge A3 is the face milling sword, and described cutting edge A4, A5, A6 are milling edges.

The diameter at described cutter cutter head place is φ d, and the diameter of protuberance is φ d1, and part to be processed aperture is φ D, and the groove in the hole directly is φ D1; φ d1-φ d=φ D1-φ D.

Processing like the hole of the said part of Fig. 1 in during the groove structure; Cutter came drilling with cutting edge A1, A2, A3 before this, get into prescribed depth after, cutter is by A4, A5, three sword millings of A6; Walk circular interpolation through Digit Control Machine Tool and carry out milling, be processed into the hole and the groove of figure one shape at last.

Being merely the preferred embodiment of the utility model in sum, is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be the technological category of the utility model.

Claims

1. a brill mills compound T type cutter; It is characterized in that: the protuberance that is provided with protrusion beyond diameter at cutter cutter head place; This protuberance outwards has cutting edge A5; Outwards have cutting edge A4, A6 on the cutter head of protuberance both sides respectively, described protuberance and cutter head connecting portion also have respectively forward and backward cutting edge A2 and A3, and the cutter head front end also has cutting edge A1; Wherein, described cutting edge A1, A2 are that the drilling sword also has face milling sword function simultaneously, and cutting edge A3 is the face milling sword, and described cutting edge A4, A5, A6 are milling edges.
