The first table surface is arranged in a plane perpendicular to the inclined main spindle and the second table surface is arranged in a horizontal plane.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method of arranging a main shaft at an angle, machining a workpiece with respect to the inclined main shaft,
The present invention relates to a machine tool in which a work is set and a product is taken out by rotating a table.

[0002]

2. Description of the Related Art Conventionally known machine tools, such as a column traverse type or a vertical type drilling tapping machine, generally have a main shaft holding a processing tool at a tip thereof arranged vertically, and machining a work with respect to the main shaft. The table for setting the work and taking out the product has a horizontal table surface, and the table is arranged to rotate horizontally for processing the work, setting the work and taking out the product. Such a machine tool is disclosed in, for example, JP-A-8-318.
No. 448. A major problem with conventionally known machine tools in which the processing table surface is configured horizontally is that
The chips generated by the processing fall and accumulate on the table surface, and the chips cannot be removed properly. In addition, since the tool magazine containing multiple processing tools is mounted in a state inclined forward with respect to the vertical main shaft, it is necessary to adopt a structure that receives the weight of the tool magazine and does not displace the main shaft. Therefore, it is necessary to make the structure around the main axis complicated and have a structure having sufficient strength.

[0003]

SUMMARY OF THE INVENTION According to the present invention, it is possible to satisfactorily remove cutting debris from a processing table surface when processing a work, and to provide an inclined surface orthogonal to a main axis at which a table surface for processing a work is inclined. It is an object of the present invention to set a workpiece and take out a product on a horizontal table surface.

[0004]

In order to solve the above-mentioned problems, the present invention adopts a first table in which a main axis is arranged at a desired angle with respect to a vertical axis to form a machining area. A turntable having a surface and a second table surface which is located outside the machining region and which constitutes a work attachment and product takeout region, is rotatably provided on a rotating shaft positioned at the center of both surfaces; The surface is arranged on a plane orthogonal to the inclined main axis, and the second table surface is arranged on a horizontal plane.

[0005] A tool magazine accommodating a plurality of working tools is vertically arranged, and the space above the second table surface is opened as a space. Further, the turntable is characterized in that it can be rotated 180 degrees back and forth.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below. The drawing shows a vertical drilling tapping machine, (1) is a spindle, (2) is a tool magazine, and both are inclined angles such that the tool magazine (2) is positioned vertically, and the spindle (1) is Attached to column (3). The column (3) is mounted on the saddle (4) so as to be movable back and forth. A plurality of machining tools (5) are stored in the tool magazine (2) as conventionally known, and the tool magazine (2) is rotated to determine a desired tool (5), and the tool is attached to the tip of the spindle (1). It can be mounted and exchanged freely. By arranging the tool magazine (2) having a considerable weight vertically by accommodating a plurality of tools, the weight of the tool magazine (2) is added only in the vertical direction. Since no weight is applied, the support of the tool magazine (2) and the structure or strength around the main axis can be simplified,
There is an advantage that cost can be reduced.

A turntable (6) has a first table surface (6a) and a second table surface (6b), and the first table surface (6a) is located below the main shaft (1). And has an inclined angle perpendicular to the main axis. The second table surface (6b) is located outside the machining area below the spindle (1),
It is positioned on a horizontal plane. That is, the turntable (6) has two table surfaces (6a) (6) at the center.
b), and the two table surfaces are inclined at an angle to each other. A turning shaft (7) is attached to the center of the turntable (6), that is, the boundary between the two table surfaces inclined with respect to each other, and the turntable (6) is capable of rotating back and forth by 180 °. A first table surface (6a) located below the main spindle (1) is located in a work processing area of a work by a processing tool (5) attached to a tip of the main spindle (1), and a second table surface located horizontally. The table surface (6b) is located in a work mounting and product take-out area. Due to the rotation of the turntable (6), the second table surface (6b) positioned horizontally moves below the main spindle (1), and conversely, the first table surface (6a) moves to a horizontal plane. Thus, the machining area is replaced with the area for attaching the work and the area for taking out the product. Above the second table surface (6b)
Since the tool magazine (2) is disposed vertically, the tool magazine (2) is opened as a large space as compared with the conventional tool magazine (2) that is disposed inclined forward, and as a result, the second table is opened. There is an advantage that the work can be easily attached to the surface (6b) or the product can be easily taken out. The turntable (6) is not necessarily required to be reciprocally rotatable 180 °, but may be rotatable in the same direction.

Since the first table surface (6a) which is located below the main spindle and holds the work and forms a machining area is a surface which is inclined in accordance with the inclination of the main spindle, the processing tool (5)
The cutting chips generated by the cutting process fall down along the inclined surface, and do not remain on the table surface, so that the cutting chips can be easily removed. Further, since the second table surface (6b) constituting the work mounting and product take-out area is located on a horizontal plane, it is easy to mount the work and take out the product. Note that the terms first and second table surfaces are not terms indicating a specific surface of the table, but the surface located in the processing area is expressed as the first table surface, and the first and second table surfaces are used in the work mounting and product removal areas. This is an abstract term in which the located surface is expressed as a second table surface, and the surfaces expressed in terms of the first and second table surfaces differ depending on the rotation of the table (6). .

[0009]

According to the present invention, since the table surface forming the machining area is inclined, it is easy to remove cutting chips, and the table surface located in the work mounting and product removal area is horizontal. As a result, the workability of attaching the work and taking out the product is improved.
