Abstract

A milling cutter disclosed by the utility model belongs to the technical field of milling cutters, and particularly relates to a milling cutter for machining upper and lower flanged exhaust outlets of air conditioner compressors. The technical problem to be solved is to provide the milling cuter which slightly vibrates in the process of machining and can guarantee good annular plane roughness. In the adopted technical scheme, the milling cutter comprises a cutter arbor and a cutter bit, the cutter bit comprises two planar edges and an annular edge, the annular edge is positioned on the frontmost end of the cutter bit, the two planar edges are positioned on both sides of the annular edge, annular grooves are respectively arranged at positions on the two planar edges, which abut against the annular edge, one of the two planar edges is provided with a crescent, and the other planar edge is provided with two crescents. Since the planar edges of the milling cutter are provided with the three crescents, vibration is reduced in the process of machining, so that the roughness of the annular planes of the annular raised parts of the upper and the lower flanged exhaust outlets of an air conditioner compressor can become good, and thereby the tightness of the air conditioner compressor can meet the requirement.

Description

A kind of milling cutter

Technical field

A kind of milling cutter of the utility model belongs to the milling cutter technical field, particularly relates to a kind of milling cutter of processing lower flange exhaust outlet on the compressor of air conditioner.

Background technology

To use milling cutter during the ring plain of ring-like bossing of lower flange exhaust outlet on the processing compressor of air conditioner, and plain cutter, blade is longer, add man-hour because the stiff problem of machine tool system, tend to produce vibration, so just have influence on the roughness of the ring plain of annular portions, make the sealing property variation of workpiece, thereby influence product quality.

The utility model content

The utility model overcomes the deficiencies in the prior art, and technical problem to be solved makes the good milling cutter of ring plain roughness for providing in a kind of process vibration little.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of milling cutter, comprise knife bar and cutter head, cutter head comprises that the plane blade divides and annular blade branch, and annular sword is positioned at cutter head foremost, and two plane swords are positioned at the both sides of annular sword, position near annular sword on two plane swords has cannelure, described two plane swords have a crescent on the plane sword, have two crescents on another plane sword.

The beneficial effect that the utility model is compared with prior art had is:

The utility model has been driven 3 crescents on the sword of the plane of milling cutter, so just reduced the working (finishing) area of each blade, also reduced the vibration in the process, the roughness of the ring plain of the ring-like bossing of lower flange exhaust outlet on the compressor of air conditioner has been improved, thereby make sealing reach requirement.

Description of drawings

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

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

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

Among the figure: 1 is knife bar, and 2 is cutter head, and 3 is crescent, and 4 is cannelure, and 5 is the plane sword, and 6 is annular sword.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of milling cutter of the utility model, comprise knife bar 1 and cutter head 2, cutter head 2 comprises plane sword 5 parts and annular sword 6 parts, and annular sword 6 is positioned at cutter head 2 foremost, and two plane swords 5 are positioned at the both sides of annular sword 6, position near annular sword 6 on two plane swords 5 has cannelure 4, described two plane swords 5 have a crescent 3 on one of them plane sword 5, have two crescents 3 on another plane sword 5.

Claims (1)

1. milling cutter, comprise knife bar (1) and cutter head (2), cutter head (2) comprises plane sword (5) part and annular sword (6) part, annular sword (6) is positioned at cutter head (2) foremost, two plane swords (5) are positioned at the both sides of annular sword (6), the position of going up near annular sword (6) at two plane swords (5) has cannelure (4), it is characterized in that: described two plane swords (5), have a crescent (3) on the plane sword (5), have two crescents (3) on another plane sword (5).
