Abstract

The utility model belongs to aviation product processing field relates to a double-sided machining dish milling cutter. The cutter comprises a cutter bar and a cutter head, wherein the cutter head is embedded with a cutter blade, the diameter of the cutter head is larger than that of the cutter bar, the cutter blade is divided into odd teeth and even teeth, the angles of the odd teeth and the even teeth are respectively the same as those of parts to be machined on two sides of a disc, and the odd teeth and the even teeth are designed in a staggered manner; the blade length is greater than the blade seat length. The two-sided chamfer can be simultaneously processed once, the processing time is saved, the processing quality is improved, and the problem of limited space can be solved simultaneously because the milling cutter is disc-shaped.

Description

Double-side processing disc milling cutter

Technical Field

The utility model belongs to aviation product processing field relates to a double-sided machining dish milling cutter.

Background

For a disc with two sides needing to be processed with chamfers, the conventional processing method is to respectively perform turning processing on the front side and the back side or use a chamfer cutter to perform machining on the front side and the back side, the double-side chamfers are processed by the method twice, two parts of clamping, alignment, pressing, processing and measurement are required, time is wasted, and the two processing methods are difficult to process under the condition that the disc is positioned inside a part and at an inlet. The cutting force is offset by the bidirectional simultaneous machining.

SUMMERY OF THE UTILITY MODEL

Aiming at the disc with two sides needing to be processed with chamfers, a disc milling cutter with two sides processed is developed.

Technical scheme

A double-sided processing disc milling cutter comprises a cutter bar and a cutter head, wherein a blade is inlaid on the cutter head, the diameter of the cutter head is larger than that of the cutter bar, the cutter head is divided into odd-numbered teeth and even-numbered teeth, the angles of the odd-numbered teeth and the even-numbered teeth are respectively the same as those of parts to be processed on two sides of a disc, and the odd-numbered teeth and the even-numbered teeth are designed in a staggered mode; the blade length is greater than the blade seat length.

Technical effects

The two-sided chamfer can be simultaneously processed once, the processing time is saved, the processing quality is improved, and the problem of limited space can be solved simultaneously because the milling cutter is disc-shaped.

Detailed Description

The double-sided machining disc milling cutter comprises a cutter bar and a cutter head, wherein a blade is inlaid on the cutter head, the diameter of the cutter head is larger than that of the cutter bar, the cutter head is divided into odd teeth and even teeth, the angles of the odd teeth and the even teeth are respectively the same as those of parts to be machined on two sides of a disc, and the odd teeth and the even teeth are designed in a staggered mode, so that the disc milling effect is better, and errors are reduced; the blade length is greater than the blade seat length.

The double-sided machining disc milling cutter is made of steel, so that the overall rigidity of the cutter is good.

The blade is replaceable, and does not need to be integrally replaced after being worn, so that the economical efficiency is good.

The thickness of tool bit is according to the length design of tool bit, guarantees that the rigidity is good.

The blade thickness is 4 mm.

The blade is made of alloy, and the hardness of the blade is high.

After the cutter rotates, the track formed by the two teeth is the same as the angle of two sides to be machined, and the machining program can be adjusted according to the size of a disc to be machined.
