Description

[0001] The present invention relates to a two-way work type angle head,

[0001] The present invention relates to an angle head, and more particularly, to an angle head in which, when cutting a workpiece, the inner surface of one side or one side of the workpiece is cut, then the cutting tool coupled to one side of the angle head is removed, And a cutting tool is provided on both sides of the angle head to improve the efficiency and productivity of the cutting operation. [0002] The present invention relates to an angle head, .

Angle head is used when the direction of the main spindle of the machine tool and the direction of approach of the cutting tool are different in the process of machining using machine tools such as machining center, milling machine, boring machine, etc. Which means one of the tools.

That is, an angle head can be used when the end milling is performed in the horizontal direction on the side surface of the workpiece using a machining center or a milling machine in which the direction of the spindle is formed in the vertical direction.

The angle head, which is mounted on the spindle of the machine tool when machining the inner diameter of the workpiece horizontally in the structure as described above, is constructed by modifying a milling machine or the like to process the inner diameter portion of the metal bearing used for the grinder spindle, And then the tool is horizontally mounted on the stern, and the rotational force is transmitted to the tool.

In the case of adopting such a machining method, a separate index device is installed in the milling machine to control an arbitrary position, and the machining range of the inner diameter is limited, so that only the designated inner diameter is used, It is impossible to apply the structure.

Therefore, it is difficult to secure the various types of grinder spindle structure due to the difficulty of machining due to the structural limitation of the metal bearings used in the grinding machine in the present machine tool maker.

In addition, in the case of an angle head having various types of structures as well as such a structure, there is a limitation that a cutting tool is mounted on only one side. For example, after the machining of the inner side or the inner side of the workpiece is completed, So that the machining of the other inner side or the other side of the inner diameter which is not cut is completed.

However, when the above process is performed, the cutting process of the angle head is completed and then the work process is stopped for a predetermined time. Then, the cutting tool of the angle head is removed and mounted to the other side, or the angle head itself is rotated, After the work process, the uncut surface of the workpiece is processed.

As a result, it is impossible to avoid the problem that the work is stopped while the cutting tool is rotated or removed and the mounting process is performed, and the cutting tool is mounted in a range exceeding the tolerance due to immaturity or mistake in the process of mounting the cutting tool newly There is a possibility that the cutting process of the workpiece may occur, which may cause a problem in workability and a work efficiency to be greatly deteriorated, and a reliability in work may be deteriorated.
