Description

Angle head for milling machine {ANGLE HEAD FOR MILLING MACHINE}

The present invention relates to an angle head, and more particularly, to an angle head for a milling machine that can be installed to the cutting machine horizontally to the angle head installed in a conventional milling machine to process the material.

In general, a milling machine widely used in the machining field is a device mainly used to cut the surface of the material, in addition to such a smoothing operation is used to process grooves or steps on the surface of the material.

In the conventional milling machine, the table is moved horizontally and vertically while the material is fixedly mounted on the horizontal table while the rotating tool is vertically arranged at the bottom of the vertically arranged spindle. It is configured to process the material while moving to.

However, the conventional milling machine does not matter when the size of the material is small when processing grooves or steps in the material, but when the size of the material is large, it is impossible to fix the material between the cutting tool and the table. There was a problem in that a groove or a step could not be processed.

Accordingly, the present invention for solving the above problems is to provide an angle head for a milling machine that can be easily processed by installing a cutting tool horizontally in the lower portion of the angle head.

An angle head having a spindle and a cutting tool installed on the spindle and capable of processing a groove of a material at a lower end thereof, comprising: a first shaft vertically installed inside the angle head and rotating according to rotation of the spindle; A coupling coupled to the first shaft and the spindle in a state of being fitted to the first shaft and the spindle, and a first bevel gear and the first bevel gear installed at the lower end of the first shaft and rotating according to the rotation of the first shaft. A second bevel gear installed to engage the bevel gear and rotating according to the rotation of the first bevel gear, a second shaft installed to penetrate the second bevel gear and rotating according to the rotation of the second bevel gear, and the cutting To provide an angle head for a milling machine, characterized in that the tool is inserted and one side comprises a holder installed on one end of the second shaft.

According to the present invention, by installing a holder in which a cutting tool is horizontally inserted at one end of a second shaft installed under the angle head, the workpiece and the cutting tool can be coaxially positioned, thereby moving the workpiece to the workpiece. It is effective to process grooves and steps horizontally.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a three-dimensional view showing the configuration of an angle head for a milling machine of the present invention, Figure 2 is a cross-sectional view showing the configuration of an angle head for a milling machine of the present invention.

1 and 2, the angle head 10 for a milling machine of the present invention is installed on a conventional milling machine and installed on a spindle 40 that rotates with external power. At this time, the spindle 40 is installed and fixed to the spindle head 38.

Meanwhile, the first shaft 12 is vertically installed inside the angle head 10. The first shaft 12 rotates according to the rotation of the spindle 40 and rotates the cutting tool 36 to be described later. At this time, the method of fixing the first shaft 12, the coupling 42 is inserted into the spindle 40 and the first shaft 12 and the first shaft 12 and the coupling 42 to the key ( 14) and the spindle 40 and the coupling 42 are configured to be fixed with the keys 16, respectively.

On the other hand, a bearing 18 is provided in the space between the angle head 10 and the first shaft 12. The bearing 18 allows the first shaft 12 to rotate smoothly.

A first bevel gear 20 is installed at a lower end of the first shaft 12, and a second bevel gear 24 is engaged with the first bevel gear 20 at a lower end of one side of the first bevel gear 20. Is installed.

The first bevel gear 20 rotates according to the rotation of the first shaft 12 and rotates the second bevel gear 24.

The second bevel gear 24 rotates according to the rotation of the first bevel gear 20.

At this time, the second bevel gear 24 is installed so that the second shaft 24 penetrates on both sides. The second shaft 24 rotates in accordance with the rotation of the second bevel gear 24.

In addition, a bearing 26 is installed between the second shaft 24 and the angle head 10. The bearing 26 allows the second shaft 24 to rotate smoothly.

Meanwhile, a holder 34 is installed at one end of the second shaft 24, and a cutting tool 36 is fitted into the holder 34.

The holder 34 rotates according to the rotation of the second shaft 24 and rotates the cutting tool 36.

The cutting tool 36 rotates by the holder 34 and processes the side of the material 46 moving by the table 44.

Hereinafter, the operation of the angle head for a milling machine consisting of the above configuration will be described with reference to FIG.

First, when external power is applied, the spindle 40 installed in the milling machine rotates.

Subsequently, when the spindle 40 rotates, the first shaft 12 connected to the spindle 40 and the coupling 42 rotates, and accordingly, the first bevel gear installed at the lower end of the first shaft 12 ( 20) rotates.

Subsequently, when the first bevel gear 20 rotates, the second bevel gear 28 meshed with the first bevel gear 20 rotates, thereby rotating the second shaft 24.

Thereafter, when the second shaft 24 rotates, the holder 34 installed at one end of the second shaft 24 rotates, and thus the cutting tool 36 fitted to the holder 34 rotates.

Thereafter, when the table 44 moves in the direction in which the cutting tool 36 is located, the workpiece 46 fixed on the table 44 moves and thus the workpiece 46 rotates. Processed by In this case, the cutting tool 36 processes a groove or a hole or a step in the material 46.
